Description

Technical Field

[0001] This utility model relates to a hanger for replacing conveyor belt rollers. Background Technology

[0002] Replacing the trough idlers and lower parallel idlers on the conveyor belt of the coal conveying system is a large-scale task. For conveyor belts with a belt width of 1000mm or more, the idlers weigh no less than 15KG. Daily replacement of idlers mainly relies on multiple people using methods such as prying and lifting the belt, which is labor-intensive and unsafe. Summary of the Invention

[0003] To solve the above problems, this utility model provides a hanger for replacing belt conveyor idlers.

[0004] The above objectives are achieved through the following scheme:

[0005] A bracket for replacing conveyor idler rollers comprises: an upper horizontal bar, two vertical bars and a connector. The upper horizontal bar is fixed above the two symmetrical vertical bars by the connector. Each vertical bar has a base fixed at its lower end. The left end of the base is threaded with two first tightening bolts, and the upper end of the base is threaded with two adjusting bolts.

[0006] The upper crossbar is fixed with a mini manual hoist, and the mini manual hoist and the round support rod are detachably connected by a steel wire rope.

[0007] The connector includes a horizontal sleeve, with a vertical connecting rod fixed to the lower end of the horizontal sleeve, and a protrusion at the upper end of the horizontal sleeve.

[0008] The connecting rod is inserted into the vertical rod to fix the upper horizontal bar above the two vertical rods.

[0009] The raised threaded connection is equipped with a second tightening bolt. Beneficial effects

[0010] 1. This utility model eliminates the need for multiple people to pry or lift the idler rollers. The belt can be lifted using a round support rod and a 0.5T mini manual hoist, reducing manpower input and physical exertion of manual operation.

[0011] 2. This utility model avoids the risks of roller slippage and personnel imbalance that may occur during manual operation. The stable support and fixation of the hanger ensures the safety of the replacement process.

[0012] 3. This utility model can be erected on the belt conveyor frame, and the angle can be adjusted by adjusting bolts, making it suitable for inclined sections of belt conveyors; by changing the position of the upper crossbar connector, it can be used for belt conveyors of different specifications such as 1400mm and 1600mm in width, meeting the needs of various scenarios.

[0020] Reference Figures 1-6 A replacement hanger for conveyor belt idlers includes: an upper horizontal bar 2, vertical bars 3, and a connecting piece 4. The upper horizontal bar is fixed above two symmetrical vertical bars via the connecting piece. A base 6 is fixed to the lower end of each vertical bar. The hanger is vertically fixed to a frame 9 via the base. Two first tightening bolts 8 are threaded to the left end of the base to tighten the frame and prevent the hanger from sliding. Two adjusting bolts 7 are fixed to the upper end of the base to adjust the verticality of the hanger.

[0021] The upper crossbar is fixed with a mini manual hoist 17, and the mini manual hoist and the round support rod 15 are detachably connected by a steel wire rope 16. The round support rod is used to support the tape.

[0022] The main body of the connector is a horizontal sleeve 18, with a vertical connecting rod 19 fixed at the lower end of the horizontal sleeve, and a protrusion 20 at the upper end of the horizontal sleeve.

[0023] The connecting rod is inserted into the vertical rod to fix the upper horizontal bar above the two vertical rods.

[0024] The raised threaded connection is equipped with a second tightening bolt 5, which stabilizes the connection between the horizontal sleeve and the upper crossbar.

[0025] By changing the position of the variable connector on the horizontal bar, it can be adapted to different models of belt conveyor frames with a bandwidth of 1400mm or 1600mm.

[0026] The frame is fixed with a trough-shaped idler roller 11 and a lower flat idler roller 10. A tape 13 is placed on the trough-shaped idler roller and B tape 14 is placed on the lower flat idler roller.

[0027] The mini manual hoist has a lifting capacity of 0.5T.

[0028] The second tightening bolt is a detachable bolt and is M14 in size.

[0029] Both the adjusting bolt and the first tightening bolt are detachable bolts, and both are M16.

[0030] The upper horizontal bar is made of DN32 pipe, the vertical bar is made of DN40 pipe, the connecting rod is made of DN25 pipe, and the horizontal sleeve is made of DN34 pipe.

[0031] Working principle: First, assemble the hanger 1. The upper crossbar is fixed above the vertical bar through the connecting rod of the connector. The horizontal sleeve of the connector is firmly connected to the upper crossbar through the second tightening bolt. After assembly, the hanger is vertically fixed to the frame through the base. The first tightening bolt at the left end of the base tightens the frame to prevent slippage. The adjusting bolt at the upper end adjusts the verticality of the hanger. The mini manual hoist of the upper crossbar is connected to the round support rod through the wire rope. Operating the mini manual hoist can drive the round support rod to lift the tape A, so that the tape A is separated from the original position 12 of the tape of the trough roller, thus safely and conveniently completing the replacement of the roller.
