Please Focus on the Installation Method of Portable Belt Conveyor

Please Focus on  the Installation Method of Portable Belt Conveyor 

As an efficient and convenient transportation equipment, mobile belt conveyor has played an important role in the process of conveying bulk material, lump material and other materials.

Upon receipt of inquiry Mobile belt machine, our engineers according to the different needs of customers, design different bandwidth and different lengths.
However, due to the packaging volume of mobile belt conveyor is too large, in order to facilitate transport, we generally will demolish the mobile belt conveyor before shipment.Therefore,when customer received the equipment,they need to disassemble the mobile belt conveyor again.
It should be noted that, during the installation process, the core of the belt conveyor is installed to install the rope and belts.Whether they install the rope and belts correctly will impact directly on the lifting capacity and operational capabilities when using belt.
In order to allow customers to better put into use, our engineers attached the following drawings to show the installation of wire rope and belt toward:

What Should We Note During the Installation of Large Angle Belt Conveyor

Large angle belt conveyor can be transported with large inclination , it even can be vertical. It adopts sidewall belt as the main part. The advantages are: large conveying amount, small space occupation ,small noise etc. which is widely used for conveying powder, blocked material. Here PK Machinery will introduce the installation notes during installation:
1.Check whether the components of large angle belt conveyor are complete or not
Generally speaking, belt conveyor includes lots of components: head & tail frame, concave & convex segmental arc frame and middle frame, however, the quantity of trough roller frame, rollers and sealing cover is big, you need to check carefully and guarantee the components are transported to the right place.
2.Installation, positioning and welding of head and tail frame, concave and convex segmental arc frame
First of all, please find the center line of the belt conveyor by using a steel wire. When installation, please make the head & tail frame, concave & convex segmental arc frame subject to the center line.

 

3.Check belt running and adjust the belt if it runs off tracking
After installation of belt, trough roller, self-aligning roller and vertical roller, connect the power supply , run the belt and adjust the belt offset distance .
4.Installation of large dip Angle belt conveyor accessories and bolts
After adjusting the belt, you can start to install the sealing cover, head cover and fastening bolts.

Installation and Notes of Belt Conveyor Anti-rain Cover

1) Open cover and fixed cover are manufactured with the galvanized steel plate or the colorized coating steel plate. Generally ,there will be 1 piece of open cover and 7 pieces of fixed covers installed every 8 pieces covers, the 2 kinds covers also can be installed side by side alternately ( it also can be matched according to customer’s requirement). At first, fasten the fixed conveyor with drilling rivets and based on the line which is upward 30mm from the top of Z type steel, fix a mounting hole every 450mm, every piece of cover overlaps 2 wave crests. Open cover overlaps above the fixed covers in order to open conveniently.

2) The Z type steel or the connection angle iron which is the main support frame of the conveyor cover, the length is equal to the length of the installed conveyor cover
The Z type steel or the connection angle iron is welded on the channel steel or the little stiffening angle iron on both sides of the conveyor

3) Install the covers (fixed covers) from one side to another side along the conveyor, during installation, people are not allowed to stand on the covers and no hard beating and hitting is allowed.
4) Mount the fixed covers on the Z type steel with the drilling rivet. The mounting points are not less than 4 on every piece.

5) 1 piece of observation window cover could be installed every 10 pieces for convenient checking and inspecting. It is decided by users.

6) Salient point cover is only used for the salient points of the convex-concave of the conveyor. Deviation switch cover is only used for covering the deviation switch. These 2 kinds covers also can overlap the fixed covers.

4. Note

1) During the installation, please handle the anti-rain cover carefully and avoid scratching.

2) After installing the accessories, please clean the surface and paint the scratched points again.

Installation of Open Belt Conveyor Cover

View 1: Installation drawing of whole open –close type 

 

View 2: Installation drawing of half open –close type (double chip open- close type) 

 

1) installation of handle 
After overlapping the open cover and fixed cover, based on the center line of the cover, the location upward 250mm is the center line used for installing the handle (it can be adjustable according to height of the conveyor support frame). Put the handle straightly and drilling a 4－Φ5 hole, then fasten with the rivets.

2) installation of hinge 
Adjust one side of the cover up higher from the top of the Z type steel (angle iron) 5mm, inward 140mm from the front and back sides of the cover, and upward 27mm is the location of the hinge, then drill holes Φ5 and fasten with the rivet. Others holes are also fastened with the rivets. 

3) installation of the lock catch
After installing the hinge, on the other side of the cover, inward 185mm from front and back sides of the cover, then based on the bottom, upward 36mm and 77mm , drill holes Φ5 and fasten the lock with the rivet, next keeping the lock locking( clamp status), and then putting the lock nose on the Z type steel straightly and drilling hole to fasten.

4) installation of the open cover
Overlap the open cover on the bilateral fixed covers. The overlapped length should be the length of 2 pitches of waves, then put the other side of the hinge appressed on the angle iron and drill hole 4－Φ5 with the rivet fastened.

Installation of Belt Conveyor Cover Support Frame

 Belt conveyor cover is applicable to power plant, cement plant, mines and other major factories which is waterproof, dustproof and windproof, it plays a great role in reducing the loss during the process of conveying goods ,making the conveyor belt more safe and reliable in operation and purifying the environment .

As the main support frame of the conveyor cover, the length of Z type steel or the connection angle iron is equal to the length of the installed conveyor cover. Please weld the Z type steel or the connection angle iron on the channel steel or the little stiffening angle iron on both sides of the belt conveyor. If need the stiffening angle iron, at first, weld the stiffening angle iron on both sides of the conveyor, then weld the Z type steel or the connection angle iron on the stiffening angle iron, detailed steps are as following:
 1) first weld the little stiffening angle iron ∟40*40*100*4(just for reference, it also can be indicated by users) every 1.5m or 2 m on both sides of the belt conveyor ( eudipleural ). The height from the intermediate frame to the top of little stiffening angle iron should ≥50mm ( it also can be decided by users).
2) Then weld the Z type steel 30*50*30*(2.0~3.0),( just for reference, it also can be replace by angle iron) and fix it on both sides of the intermediate frame top, the inner size should be 10-20mm bigger than outside size of intermediate frame.
3) After being welded please remove welding slag then paint.
