A torsion protection device for displacement of pressure roller of tubular belt conveyor

Abstract

This invention discloses a torsion protection device for the displacement of a tubular belt conveyor's pressure roller, comprising a support frame, an operation panel, an annular frame, and a tubular belt. The support frame is a rectangular structure with a bolt-fixed hopper mounted on the top left side. An operation panel connected by an electrical wire is mounted on the front left side of the support frame. A bolt-fixed mechanical limit sensor is mounted on the top right side of the operation panel. A sensing plate is mounted at the bottom of the mechanical limit sensor, and a fixedly connected pull wire is wound around the bottom of the sensing plate. The pull wire passes sequentially through the pressure roller displacement sensing device, which is fixed to the right surface of the annular frame and symmetrically distributed. A nested, slidingly connected tubular belt is mounted inside the annular frame. This invention's torsion protection device, through its rational design, can trigger an alarm and stop the belt operation when belt bulging causes the tubular belt to deviate or twist. Simultaneously, the pressure roller displacement sensing device has a stable structure, facilitating disassembly, assembly, and maintenance.

Description

Technical Field

[0001] This invention relates to a displacement anti-torsion protection device, and more particularly to a displacement anti-torsion protection device for a tubular belt conveyor pressure wheel. Background Technology

[0002] Tubular belt conveyors are a new type of belt conveyor that completely encloses and seals the materials being transported. However, due to the large belt lifting angle and long transport distance, the materials are prone to slipping during transport, causing the belt to bulge and leading to belt misalignment and twisting. Handling this requires a huge amount of manpower and resources and affects normal production. Therefore, a new type of tubular belt conveyor pressure wheel displacement anti-twist protection device is needed that can issue an alarm when the materials slip and bulge. Summary of the Invention

[0003] The purpose of this invention is to provide a torsion protection device for the displacement of the pressure wheel of a tubular belt conveyor, so as to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A torsion protection device for pressure wheel displacement of a tubular belt conveyor includes an equipment support, a hopper, an operation panel, a mechanical limit sensor, a sensing plate, a pull wire, a pressure wheel displacement sensing device, an annular frame, and a tubular belt. The equipment support is a rectangular structure with a bolt-fixed hopper mounted on the top left side. An operation panel with an electrical connection is mounted on the front left side of the equipment support. A bolt-fixed mechanical limit sensor is mounted on the top right side of the operation panel. A sensing plate is mounted on the bottom of the mechanical limit sensor. A fixed pull wire is wound around the bottom of the sensing plate. The pull wire passes sequentially through the pressure wheel displacement sensing device. The pressure wheel displacement sensing device is fixed to the right end surface of the annular frame and symmetrically distributed. A nested slidingly connected tubular belt is mounted inside the annular frame.

[0006] Based on the above technical solution, the pressure roller displacement sensing device includes a nut, an adjusting rod, a spring, a bearing bracket, a bearing, a pulley, and a limiting screw. The adjusting rod is welded and fixed to the middle of the bottom end of the nut. A nested spring is installed on the circumferential surface of the adjusting rod. The bearing bracket is welded and fixed to the middle of the bottom end of the adjusting rod. A bearing is installed on the inner side of the bearing bracket. A pulley is installed on the circumferential surface of the bearing. The bearing and pulley are fixed to the inner side of the bearing bracket by the limiting screw.

[0007] Based on the above technical solution, the adjusting rod includes a sleeve, a first limiting plate, a second limiting plate, a buffer pad, a sleeve, a stepped internal thread, a threaded limiting cap, and a pressure plate. The top of the sleeve is equipped with an integral cylindrical first limiting plate, and the bottom of the sleeve is equipped with a threaded second limiting plate. The bottom of the second limiting plate is equipped with a fixed buffer pad. The sleeve and the bottom sleeve are slidably inserted together. The top of the sleeve has a stepped internal thread, which is threaded to the top threaded limiting cap. A pressure plate is installed on the bottom of the circumferential surface of the sleeve.

[0008] Compared with the prior art, the present invention has the following advantages: When the displacement anti-torsion protection device of the present invention encounters material sliding and swelling, the pulley at the end of the pressure roller displacement sensing device moves outward under force, causing the top pull wire to extend, and the sensing plate moves up to touch the mechanical limit sensor, thus issuing an alarm signal. At the same time, the pressure roller displacement sensing device adopts a split threaded connection method, which is convenient for installation and disassembly, and also facilitates the replacement of damaged parts, effectively reducing maintenance costs and further extending the service life of the equipment due to structural stability.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-3As shown, a torsion protection device for pressure wheel displacement of a tubular belt conveyor includes an equipment support 1, a hopper 2, an operation panel 3, a mechanical limit sensor 4, a sensing plate 5, a pull wire 6, a pressure wheel displacement sensing device 7, an annular frame 8, and a tubular belt 9. The equipment support 1 is a rectangular structure with a bolt-fixed hopper 2 installed on the top left side. The operation panel 3 with an electrical connection is installed on the front left side of the equipment support 1. The mechanical limit sensor 4 with a bolt is installed on the top right side of the operation panel 3. The sensing plate 5 is installed at the bottom of the mechanical limit sensor 4. The pull wire 6 is wound around the bottom of the sensing plate 5 and is fixedly connected. The pull wire 6 passes through the pressure wheel displacement sensing device 7 in sequence. The pressure wheel displacement sensing device 7 is fixed to the right end surface of the annular frame 8 and is symmetrically distributed. The tubular belt 9 with a nested sliding connection is installed inside the annular frame 8.

[0015] The pressure roller displacement sensing device 7 includes a nut 10, an adjusting rod 11, a spring 12, a bearing bracket 13, a bearing 14, a pulley 15, and a limiting screw 16. The adjusting rod 11 is welded and fixed to the middle of the bottom end of the nut 10. The spring 12 with a nested structure is installed on the circumferential surface of the adjusting rod 11. The bearing bracket 13 is welded and fixed to the middle of the bottom end of the adjusting rod 11. The bearing 14 is installed on the inner side of the bearing bracket 13. The pulley 15 is installed on the circumferential surface of the bearing 14. The bearing 14 and the pulley 15 are fixed to the inner side of the bearing bracket 13 by the limiting screw 16.

[0016] The adjusting rod 11 includes a sleeve 17, a first limiting plate 18, a second limiting plate 19, a buffer pad 20, a sleeve 21, a stepped internal thread 22, a threaded limiting cap 23, and a pressure plate 24. The top of the sleeve 17 is equipped with an integral cylindrical first limiting plate 18, and the bottom of the sleeve 17 is equipped with a threaded second limiting plate 19. The bottom of the second limiting plate 19 is equipped with a fixed and adhesive buffer pad 20. The sleeve 17 is slidably inserted into the sleeve 21 at the bottom. The top of the sleeve 21 has a stepped internal thread 22, which is threadedly connected to the threaded limiting cap 23 at the top. The bottom of the sleeve 21 is equipped with a pressure plate 24.

[0017] The working principle of this invention is as follows: When the material slides down and expands, the pulley at the end of the pressure roller displacement sensing device, which is in contact with the tubular belt, is forced to move outward. Then, the pulley at the end of the pressure roller displacement sensing device is displaced, and the bearing bracket drives the sleeve and the pressure plate compression spring to move outward. The top nut pulls the pull wire to extend, which in turn drives the sensing plate to move up and touch the mechanical limit sensor, and then sends an alarm signal. At the same time, the second limit plate and the threaded limit cover, which are connected to the sleeve and the rod by threads, facilitate the installation, disassembly and replacement of the two damaged parts. In addition, the buffer rubber pad provides buffer protection for the sleeve and the rod, further improving the service life of the equipment.

[0018] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
