Description

Technical Field

[0001] This utility model relates to the field of air cushion conveyor technology, specifically to a telescopic joint structure for an air cushion belt conveyor. Background Technology

[0002] In air cushion belt conveyors used for long-distance transport, the thermal expansion and contraction of the equipment often leads to deformation, misalignment, and weld cracking. It can even cause serious concentricity deviation of the coupling shaft in the power unit. Therefore, it is necessary to install expansion joints to neutralize the offset caused by thermal expansion and contraction of the equipment in order to ensure the stable performance of the air cushion belt conveyor.

[0003] In existing air cushion belt conveyor expansion joints, the expansion joint is a retractable rubber sleeve. During installation, the expansion joint is locked to the mounting plate, which is then connected to the conveyor's flange. However, this connection structure makes it impossible to check the airtightness of the connection between the expansion joint and the mounting plate. When air leakage occurs, it cannot be detected in time, affecting the efficiency of the air cushion conveyor. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a telescopic joint structure for an air cushion belt conveyor. Through the cooperation of the telescopic joint assembly and the locking and sealing indicator assembly, the airtightness of the locking telescopic joint position can be monitored in real time during use. Once an air leak occurs, bubbles will be generated so that the user can check and observe, thus avoiding the problem of air leaks not being detected in time and affecting the efficiency of the conveyor.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a telescopic joint structure for an air cushion belt conveyor, comprising:

[0006] The expansion joint assembly includes an expansion section seal, an expansion section cover covering the outside of the expansion section seal, a middle section of the obstruction plate located in the middle section of the air cushion belt conveyor, expansion section support legs located on the bottom surface of the expansion section cover, drainage pipes of the middle section of the obstruction plate located in the upper and lower parts of the middle section of the obstruction plate, a cover plate of the obstruction plate located on the top surface of the air cushion belt conveyor, and an expansion joint connecting flange fixed to the side wall of the air cushion belt conveyor.

[0007] A locking and sealing indicator assembly includes a mounting plate disposed on the sealing side of the telescopic section, a square frame fixed to the side wall of the mounting plate, a threaded hole opened on the surface of the square frame, a transparent cover disposed above the square frame, a side plate fixed to the side wall of the transparent cover, a round hole opened on the side plate, and a pipe communicating with the transparent cover.

[0008] In a preferred embodiment of the telescopic joint structure of the air cushion belt conveyor described in this utility model, the telescopic section is sealed and inserted into the square frame, and locked by bolts through the threaded holes.

[0009] In a preferred embodiment of the telescopic joint structure of the air cushion belt conveyor described in this utility model, the transparent cover covers the threaded hole, and the transparent cover is locked by bolts through the circular hole, and water is injected into the transparent cover through a pipe.

[0010] In a preferred embodiment of the telescopic joint structure of the air cushion belt conveyor described in this utility model, the telescopic section seal is installed by locking the square frame to the large flange connecting the telescopic joint.

[0011] As a preferred embodiment of the telescopic joint structure of the air cushion belt conveyor described in this utility model, it further includes a leakage indicator component, which includes a threaded through hole opened on the outer surface of the telescopic section, a threaded pipe communicating with the threaded through hole, and an annular cover communicating with the threaded pipe.

[0012] As a preferred embodiment of the telescopic joint structure of the air cushion belt conveyor described in this utility model, the air leakage indicator component further includes a long rod inserted into the threaded pipe, a crossbar fixed to the top surface of the long rod, and a first baffle and a second baffle fixed to the part of the long rod.

[0015] As a preferred embodiment of the telescopic joint structure of the air cushion belt conveyor described in this utility model, the telescopic joint assembly further includes an upper idler wheel and a lower idler wheel, which are disposed at the inlet and outlet positions of the air cushion belt conveyor trough.

[0016] Compared with the prior art, the advantages of this utility model are:

[0017] 1. By cooperating with the expansion joint assembly and the locking and sealing indicator assembly, the airtightness of the locking expansion joint position can be monitored in real time during use. Once an air leak occurs, bubbles will be generated so that the user can check and observe, thus avoiding the problem of air leaks not being detected in time and affecting the efficiency of the conveyor.

[0018] Second, by embedding the air leakage component inside the telescopic section cover, in conjunction with the telescopic section seal, the overall sealing of the telescopic section can be monitored. Once an air leak occurs, the crossbar will rotate directly to alert the staff that an air leak has occurred at this location. In this way, users can observe whether there is an air leak through the cover, further improving the convenience of air leak detection. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] This utility model provides a telescopic joint structure for an air cushion belt conveyor. Through the cooperation of the telescopic joint component and the locking and sealing indicator component, the airtightness of the locking telescopic joint position can be monitored in real time during use. Once an air leak occurs, bubbles will be generated so that the user can check and observe, thus avoiding the problem of air leaks not being detected in time and affecting the efficiency of the conveyor.

[0036] Figures 1-9 The diagram shown is an overall structural schematic of one embodiment of the telescopic joint structure of an air cushion belt conveyor according to this utility model. Please refer to [link / reference]. Figures 1-9 The main structure of this embodiment includes: a telescopic joint assembly and a locking and sealing indicator assembly.

[0037] The expansion joint assembly is used in air cushion belt conveyors to achieve changes in conveyor belt length. Specifically, the expansion joint assembly includes an expansion section seal 1, an expansion section cover 2 covering the outside of the expansion section seal 1, a middle section of the obstruction plate 3 located in the middle section of the air cushion belt conveyor, an expansion section support leg 4 located on the bottom surface of the expansion section cover 2, a middle section drain pipe 7 located in the upper and lower parts of the middle section of the obstruction plate 3, a cover plate 8 located on the top surface of the air cushion belt conveyor, and an expansion joint connecting flange 9 fixed to the side wall of the air cushion belt conveyor.

[0038] The expansion joint assembly also includes an upper idler wheel 5 and a lower idler wheel 6, which are located at the inlet and outlet positions of the air cushion belt conveyor trough.

[0039] In practical use, the telescopic section seal 1 is a rubber sleeve connected to the telescopic joint connecting flange 9. While ensuring telescopic movement, it also ensures the sealing of the entire equipment. The telescopic section outer cover 2 is also installed on the telescopic joint connecting flange 9. At the same time, it is outside the telescopic section seal 1 and protects the telescopic section seal 1 from damage by external objects. The end face of the obstruction plate middle section 3 is in the form of upper and lower obstruction plates, which separates the air chamber of the middle section of the air cushion belt conveyor, ensuring the integrity of the air chamber and preventing air leakage. The telescopic section support legs 4 can be adjusted up and down to support the telescopic section on the ground and can move with the telescopic joint. The upper idler wheel 5 and the lower idler wheel 6 are set at the inlet and outlet of the air cushion belt conveyor trough. When the belt passes through the telescopic joint, it ensures smooth belt operation and prevents edge rubbing. The obstruction plate middle section drain pipe 7 is set at both the upper and lower air chambers of the obstruction plate middle section 3. If water vapor accumulates at the air chamber split, it can be discharged through the obstruction plate middle section drain pipe 7.

[0040] The locking and sealing indicator assembly helps users detect air leaks. Specifically, the locking and sealing indicator assembly includes a mounting plate 11 disposed on the side of the telescopic section seal 1, a square frame 12 fixed to the side wall of the mounting plate 11, a threaded hole 13 opened on the surface of the square frame 12, a transparent cover 14 disposed above the square frame 12, a side plate 15 fixed to the side wall of the transparent cover 14, a round hole 16 opened on the side plate 15, and a pipe 17 communicating with the transparent cover 14.

[0041] In practical use, the telescopic section seal 1 is inserted into the square frame 12 and locked by bolts through the threaded holes 13. Then, the transparent cover 14 is placed over the threaded holes 13 and locked by bolts through the round holes 16. Water is injected into the transparent cover 14 through the pipe 17. At this time, the liquid water covers the distributed threaded holes 13. In this way, when the telescopic section seal 1 leaks, bubbles will be generated in the liquid water, so that the user can check whether there is a leak.

[0042] Furthermore, it also includes a leakage indicator assembly, which includes a threaded through hole 21 opened on the surface of the telescopic section outer cover 2, a threaded tube 22 communicating with the threaded through hole 21, and an annular cover 23 communicating with the threaded tube 22; the leakage indicator assembly also includes a long rod 24 inserted into the threaded tube 22, a crossbar 25 fixed to the top surface of the long rod 24, a first baffle 26 and a second baffle 27 fixed to the rod portion of the long rod 24; the leakage assembly also includes a flat plate 28 fixed to the inner wall of the annular cover 23, a through hole 29 opened on the surface of the flat plate 28, and a fan blade 210 fixed to the end of the long rod 24;

[0043] In practical use, the threaded through hole 21 is connected to the threaded pipe 22, the long rod 24 passes through the through hole 29, and the first baffle 26 and the second baffle 27 are located on the upper and lower sides of the plate 28 respectively. When air leakage occurs in other parts of the telescopic section seal 1, the gas will impact inside the telescopic section outer cover 2. At this time, the fan blade 210 drives the long rod 24 to rotate, and the first baffle 26 and the second baffle 27 limit the rotation of the long rod 24 along the through hole 29. At this time, the crossbar 25 will also rotate. This can indicate whether the entire telescopic section seal 1 is leaking in real time, which is convenient for monitoring.

[0044] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
