Description

Technical Field

[0001] This invention relates to the field of replacement tool technology, and more particularly to a belt replacement tool. Background Technology

[0002] In industrial and mining enterprises, belt conveyors are widely used to transport various solid lumps and powders, enabling continuous, high-efficiency, and steep-angle transport. The conveyor belt plays the role of carrying and transporting materials in the belt conveyor. After long-term use, problems such as longitudinal tearing, surface cracking, and belt surface damage are prone to occur, requiring replacement as needed.

[0003] In actual operation, for the convenience and operability of changing operations, the annular conveyor belt is generally composed of long strips of belt joined together at both ends; when assembling, the two ends of the belt (conveyor belt) are joined by buckles or by hot vulcanization joints.

[0004] When replacing a belt, one end of the new belt (the replacement belt) is usually fixed to the old belt (the belt to be replaced). The rotation of the old belt drives the new belt to be laid around the rollers on the belt conveyor. The old belt is removed in coordination with the operation of the belt conveyor's tensioning components. Then, the ends of the new belt are connected and the relative positions of the new belt and other components on the belt conveyor are adjusted before tensioning it, thus completing the belt replacement.

[0005] In the existing technology, the replacement of conveyor belts is mostly done manually. The operation is labor-intensive, requires the cooperation of multiple people, takes a long time, and has low efficiency, resulting in long downtime of the belt conveyor and thus affecting production operations. In existing technologies, when replacing belts, one end of the new belt needs to be fixed to the old belt and moved by the old belt. However, the new belt is heavier, and if the new and old belts are combined in a non-destructive way, the connection is less reliable and is prone to breakage at the connection point. If the new and old belts are fixed in a destructive way, although it is more secure, it will damage the new and old belts, affecting their service life and subsequent reuse.

[0006] Furthermore, if the belt conveyor is empty or the old belt has broken when the new belt is installed, it is impossible to use the old belt to pull the new belt. In addition, the working space at the work site is limited, making the work more difficult and labor-intensive, and the work efficiency is also lower.

[0007] Therefore, there is a need for a belt replacement tool that can assist operators in efficiently and conveniently completing belt replacement work on belt conveyors, requires no multiple people to work together during belt replacement, has low labor intensity, and even if the old belt cannot be used to pull the new belt, the actual operation difficulty is still low and the operation efficiency is still high.

The axial direction of the rotating shaft is the same as that of the horizontal rotating column 140, and it rotates under the coordinated control of the power component and the control unit. The clamping drive assembly is used to assist in the retrieval and deployment of the belt by clamping the belt with two conveyor belt structures arranged one above the other and pulling it to move it.

Both the top conveyor assembly 430 and the bottom conveyor assembly 440 are conveyor belt structures positioned on a rigid support. They are arranged opposite each other, one above the other. Each includes an annular belt and a horizontally placed roller for opening the annular belt and driving it to rotate. The axial direction of the roller is the same as the axial direction of the rotation shaft of the supporting rotating rod 300. The annular belts on the top conveyor assembly 430 and the bottom conveyor assembly 440 are made of non-metallic material. When the belt needs to be moved, insert the belt to be moved between the top conveyor assembly 430 and the bottom conveyor assembly 440, and then control the extension of the displacement telescopic body 420 so that the top conveyor assembly 430 and the bottom conveyor assembly 440 clamp the belt; at this time, control the top conveyor assembly 430 and the bottom conveyor assembly 440 to rotate synchronously so that the belt can be moved by friction. The auxiliary belt deployment assembly is used to deploy an auxiliary belt body on the belt conveyor as needed, including an auxiliary belt 510, a first take-up and release assembly 520, and a second take-up and release assembly 530. like Figure 7 As shown, the auxiliary belt 510 is made of metal or non-metal material, with a width of less than 30 cm and an overall weight of less than 5 kg. One end is positioned with an end positioning body 512. The auxiliary belt 510 can be detachably fixed to the end of the belt through the end positioning body 512. Both the first take-up and release assembly 520 and the second take-up and release assembly 530 are roll structures, and each has a fixing clip 522 positioned on its side wall. They are controlled to take up and release the auxiliary belt 510. The first take-up and release assembly 520 is positioned on the top of the U-shaped frame 410. The second take-up and release assembly 530 is positioned on the top of the base carrier 200. The fixing clip 522 is a manual or electric clip used to fix the end of the auxiliary belt 510.

[0031] Furthermore, the top conveying assembly 430 includes a support frame 431, a first rotating column 432, a second rotating column 433, and an annular belt 434. The support frame 431 is a rigid support that serves to bear and support the load, and is fixed to the bottom of the displacement telescopic body 420. The first rotating column 432 and the second rotating column 433 are both horizontally placed rollers, rotatably connected to the support frame 431, with a distance greater than 40 centimeters between them. At least one of them rotates under the coordinated control of the power assembly and the control unit. The support frame 431 is located above the first rotating column 432 and the second rotating column 433. The annular belt 434 is an annular belt that is sleeved on the first rotating column 432 and the second rotating column 433, and is stretched into an elongated shape by the first rotating column 432 and the second rotating column 433 and is always in a taut state.

[0032] Furthermore, the bottom conveying assembly 440 includes a support frame 441, a first carrier column 442, a second carrier column 443, and a matching belt 444. The support frame 441 is a rigid support that provides load-bearing support and is fixed to one end of the U-shaped frame 410 away from the displacement telescopic body 420, located below the first carrier column 442 and the second carrier column 443.

[0033] Preferably, the supporting rotating rod 300 is a telescopic rod structure, which can extend and retract under the coordinated control of the power component and the control unit, thereby adjusting the distance between the clamping drive component and the base vehicle 200 as needed, thus facilitating the belt replacement operation.

[0034] Preferably, the replacement belt 001 is formed into an annular belt body by belt buckles (metal buckles); both ends of the replacement belt 001 are fixed with a row of end buckles 010; the two rows of end buckles 010 are combined to form a belt buckle; the end buckle 010 is U-shaped in general, and its end is embedded and fixed in the belt; after the two rows of end buckles 010 at both ends of the replacement belt 001 are inserted into the gap between each other in an alternating manner, the metal wire can be passed through the two rows of end buckles 010 at the same time to realize the docking combination of the ends of the replacement belt 001, which is the prior art; the structure of the end positioning body 151 and the end positioning body 512 is a row of end buckles 010.

[0036] The power unit is used to provide power for the operation of each component of the belt changing tool of this application, and the control unit plays the role of controlling the coordinated operation of each component of the belt changing tool. Both of these are existing technologies and will not be described in detail here.

[0037] Preferably, the control unit includes a remote controller.

[0038] like Figure 8 As shown, when using the belt replacement tool of this application: First, push the base carriage 200 closer to the bottom of the belt conveyor; adjust the position of the clamping drive assembly so that it is close to one side of the belt conveyor; push the belt take-up and release assembly closer to the side of the base carriage 200 away from the belt conveyor. Control the operation of the belt conveyor so that the seam of the belt to be replaced 002 is close to the clamping drive assembly; wipe a clean area of ​​the top surface of the replacement belt 001 near the clamping drive assembly; control the first take-up and release assembly 520 to release part of the auxiliary belt 510 and use tape 511 to stick one end of the auxiliary belt 510 to the clean area of ​​the replacement belt 001. The belt conveyor is controlled to rotate the belt to be replaced 002, and the first take-up and release component 520 is controlled to release the auxiliary belt 510 synchronously. When the belt to be replaced 002 moves the auxiliary belt 510 to a position close to the base vehicle 200, the tensioning component 006 of the belt conveyor is controlled to operate, so that the belt to be replaced 002 is in a loose state. The belt pulling assembly is controlled to move laterally as a whole, so that the belt to be replaced 002 is inserted between the top conveyor assembly 430 and the bottom conveyor assembly 440. Then, the top conveyor assembly 430 is controlled to move down to clamp the belt to be replaced 002. Remove the end of the auxiliary belt 510 from the belt to be replaced 002 and secure it to the second take-up and release assembly 530; Disconnect the belt 002 to be replaced from the position near the base vehicle 200; control the operation of the top conveyor assembly 430 and the bottom conveyor assembly 440 to drag the disconnected belt 002 to be replaced and move it; fix the end of the belt 002 to be replaced near the clamping drive assembly to the belt take-up assembly; The coordinated operation of the clamping drive assembly and the rotation of the transverse rotating column 140 cause the belt 002 to be replaced to be gradually and completely wound onto the bearing tube 150. The vertical support rod 120 is shortened so that the coiled belt 002 that needs to be replaced contacts the ground; the fixing pin 141 is released from fixing the support tube 150 and the belt take-up and unwinding assembly is pushed to move laterally, so that the support tube 150 is separated from the horizontal rotating column 140. Transport away the roll of belt 002 that needs to be replaced; before transporting away, release the carrier tube 150 on the belt 002 that needs to be replaced from the belt 002 and pull it out directly, or remove the carrier tube 150 before the next use. Control the second take-up and unwind assembly 530 to take up the auxiliary tape 510, and control the first take-up and unwind assembly 520 to release the auxiliary tape 510 at the same time, so that the first take-up and unwind assembly 520 completely releases the auxiliary tape 510. The replacement belt 001, which is rolled up and has a carrying tube 150 as the inner core, is positioned and transported to a position close to the belt pulling assembly using the belt take-up and unwinding assembly. Control the horizontal rotating column 140 to rotate; insert one end of the replacement belt 001 into the clamping drive assembly; control the clamping drive assembly to run, causing the replacement belt 001 to pass through the clamping drive assembly; remove the end of the auxiliary belt 510 from the first take-up and release assembly 520 and fix it to the end of the replacement belt 001. The coordinated operation of the clamping drive assembly and the rotation of the transverse rotating column 140 cause the replacement belt 001 to gradually form a loop on the belt conveyor; the auxiliary belt 510 is removed from the end of the replacement belt 001; and the two ends of the replacement belt 001 are connected and combined together. Adjust the position of the replacement belt 001 by pushing or pulling it from the side to move it to the installation position (ensuring that the replacement belt 001 is not tilted or misaligned) and control the tensioning component 006 to tension the replacement belt 001 to complete the belt replacement; Then, the end of the auxiliary belt 510 is fixed to the first take-up and release assembly 520, and the first take-up and release assembly 520 and the second take-up and release assembly 530 work together to rewind the auxiliary belt 510 onto the first take-up and release assembly 520.

[0039] If there is no old belt on the belt conveyor (no need to replace belt 002) or the belt 002 to be replaced is broken when it is necessary to install and replace belt 001, the auxiliary belt 510 shall be laid manually. Because the auxiliary belt 510 is light and small in size, it is simple and convenient to lay and the labor intensity is low.

[0040] Preferably, a detachable sleeve 521 is detachably fixed to the first take-up and release assembly 520; after the detachable sleeve 521 is fixed to the first take-up and release assembly 520, it rotates under the drive of the first take-up and release assembly 520; the auxiliary belt 510 has various specifications, and the lengths of different specifications are different, thus adapting to belt conveyors of different lengths; the belt replacement tool of this application is equipped with multiple auxiliary belts 510 of different specifications, and also with multiple detachable sleeves 521; the detachable sleeves 521 correspond one-to-one with the auxiliary belts 510; the auxiliary belts 510 are normally wound on the detachable sleeves 521, and when in use, they are selected as needed and installed on the first take-up and release assembly 520.

[0041] Preferably, both the belt retraction assembly and the belt pulling assembly have a built-in travel system at their bottoms, enabling them to move in a controlled manner.

[0042] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: This invention solves the technical problems of high labor intensity, high operation difficulty, low operation efficiency, and the need for multiple people to cooperate when replacing conveyor belts in the existing technology; it realizes the technical effect that the belt replacement tool can assist operators to complete the belt replacement operation of the conveyor belt efficiently and conveniently, without the need for multiple people to cooperate and with low labor intensity.

[0043] Example 2

[0044] Considering the low efficiency, high labor intensity, and difficulty of manually adjusting the position of the replacement belt 001, this application embodiment optimizes and improves the structure of the top conveyor assembly 430 based on the above embodiment. The deformation of the top conveyor assembly 430 guides the correction of the position of the replacement belt 001. Specifically: like Figures 9 to 11 As shown, the first rotating column 432 and the second rotating column 433 have the same structure, both including a base column, a connecting column 435 and a matching column; the base column, the connecting column 435 and the matching column are combined to form a horizontally placed roller that can be extended and retracted as needed; The base column is a rigid cylinder; the connecting column 435 is a horizontally placed polygonal column, coaxial with the base column, and fixed to one end of the base column; the matching column is a rigid column with a deep hole at one end that matches the connecting column 435; the connecting column 435 is inserted into and slidably positioned within the matching column. The top conveyor assembly 430 has two annular belts 434, each with a width greater than 20 centimeters. Both the base column and the matching column have annular grooves positioned on their side walls to restrict the movement of the annular belt 434. Two annular belts 434 are respectively fitted onto two foundation columns and two matching columns, and are all in a taut state; The support frame 431 includes a horizontal frame 436 and two side frames 437; The horizontal frame 436 is a horizontally positioned rod-shaped frame that can extend and retract as needed. It includes a base section and sliding sections at both ends of the base section. Both sliding sections are slidably positioned on the base section and slide under the coordinated control of the power component and the control unit. During sliding, the entire horizontal frame 436 extends and retracts. The base section of the horizontal frame 436 is fixed on the displacement telescopic body 420. Both side frames 437 are U-shaped frames with downward openings, respectively positioned at both ends of the horizontal frame 436. The ends of the first rotating column 432 and the second rotating column 433 are respectively positioned on the two side frames 437. When the horizontal frame 436 extends and retracts, it drives the first rotating column 432 and the second rotating column 433 to extend and retract. Side limiting bodies are positioned at the bottom of both side frames 437; the main body of the side limiting body is a vertical column structure or a horizontal ring structure. When clamping the conveyor belt of the drive assembly, the side limiting bodies are located on both sides of the conveyor belt; during the clamping process of the conveyor belt of the drive assembly, the clamping of the belt is periodically loosened and the length of the horizontal frame 436 is gradually adjusted. The side limiting bodies apply pressure to the side of the belt, thereby gradually adjusting the relative position between the belt of the belt conveyor as a whole and other components of the belt conveyor during the belt movement; before the belt 001 is replaced and tensioned, the top conveyor assembly 430 is moved upward and the belt pulling assembly is moved horizontally so that the belt pulling assembly is disengaged from the belt conveyor. The first carrier post 442 and the second carrier post 443 of the bottom conveying assembly 440 are each provided with annular grooves on the side walls near the middle for limiting the matching belt 444; the width of the matching belt 444 is smaller than the width of the annular belt 434, and it is sleeved on the first carrier post 442 and the second carrier post 443.

[0045] Preferred, such as Figure 9 and Figure 10 As shown, the number of side limiting bodies is four or more, and at least one side limiting body is fixed to the bottom of each side frame 437; the side limiting body includes a vertically placed side limiting post 451 and a carrier body 452 for supporting and positioning the side limiting post 451; the side limiting post 451 is a cylinder with its axis perpendicular to the length direction of the annular belt 434, and is rotatably connected to the carrier body 452 around its own axis; the carrier body 452 is a rigid support and is fixed to the bottom of the side frame 437; the bottom end of the side limiting post 451 is 2 to 3 cm lower than the bottom surface of the annular belt 434; when clamping the conveyor belt of the drive assembly, the side limiting post 451 abuts against the side of the belt, applying pressure from both sides to gradually align it; before the replacement belt 001 is tensioned, the control top conveyor assembly 430 is moved upward and the belt pulling assembly is moved laterally as a whole so that the belt pulling assembly is disengaged from the belt conveyor.

[0046] Preferred, such as Figure 11 As shown, there are two side limiting bodies, namely limiting belts 453; the limiting belts 453 are non-metallic rings with rounded rectangular cross-sections; an annular groove for accommodating and limiting the limiting belts 453 is positioned on both the base column and the matching column; the annular groove for accommodating and limiting the limiting belts 453 is located near its own positioning end on the base column and the matching column; when clamping the conveyor belt of the drive assembly, the limiting belts 453 abut against the side of the belt, applying pressure from both sides to gradually align it.

[0047] Preferably, a laser positioning component 600 is positioned on the top of the clamping drive assembly; the laser positioning component 600 is a visible laser emitter, which projects multiple laser beams onto the replacement belt 001 and other components of the belt conveyor during operation, providing a reference for the position adjustment of the replacement belt 001 and the position adjustment of the clamping drive assembly, so as to improve the adjustment efficiency and accuracy of the replacement belt 001.

[0048] Preferably, during the process of adjusting the position of the replacement belt 001 using the side limiting body, such as Figure 12As shown, the replacement belt 001 is straightened by controlling the clamping drive assembly to rotate around the support rotating rod 300; after adjusting the position of the replacement belt 001, the clamping drive assembly is controlled to gradually loosen the replacement belt 001 while the tensioning assembly 006 is controlled to gradually straighten the replacement belt 001; before the replacement belt 001 is fully tensioned, the top conveyor assembly 430 is controlled to move upward and the belt pulling assembly is controlled to move laterally so that the belt pulling assembly is disengaged from the belt conveyor, thereby reducing the positional displacement of the replacement belt 001 during the tensioning process.

[0049] Considering that once the replacement belt 001 is tensioned, adjusting its position relative to other components of the belt conveyor is quite difficult; to address the above issues, such as... Figure 13 and Figure 14 As shown, preferably, the uppermost and horizontally positioned section of the U-shaped frame 410 is a telescopic section 411; the telescopic section 411 is a telescopic rod structure, preferably a multi-stage telescopic rod, which extends and retracts under the coordinated control of the power component and the control unit, and the length that can be extended is greater than the length of the first carrier column 442 of the bottom conveyor assembly 440; before the replacement belt 001 is tensioned, the control telescopic body 420 is contracted to avoid the presence of the side limiting body restricting the lateral movement of the bottom conveyor assembly 440, and the extension of the telescopic section 411 is controlled to push the base carrier 200 to move in the opposite direction at the same time, so that the bottom conveyor assembly 440 is pulled out from the space enclosed by the replacement belt 001; the top conveyor assembly 430 is controlled to move and deform, so that the side limiting body abuts against the replacement belt 001; the belt conveyor drives the replacement belt 001 to rotate, and gradually completes the tensioning operation of the replacement belt 001; because the side limiting body abuts against the replacement belt 001, the replacement belt 001 is less likely to deviate during the tensioning process.

For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
