Abstract
Description
Technical Field
[0001] This application relates to the technical field of idler replacement equipment, and in particular to a convenient replacement device for conveyor belt idlers. Background Technology
[0002] In mining, ports, metallurgy, and other fields, conveyor belts are the core equipment for continuous material transport. Idler rollers, as key components supporting the conveyor belt, are prone to wear and tear, such as delamination and breakage, during long-term operation. If not replaced in time, faulty idlers will exacerbate conveyor belt wear, leading to belt misalignment, material spillage, and in severe cases, conveying interruption, thus affecting the normal operation of the production system. Therefore, timely replacement of idlers is crucial.
[0003] When replacing idlers, tools such as chain hoists and wire ropes are needed to support the conveyor belt first to counteract the weight and tension of the conveyor belt, so that the conveyor belt and idlers are separated to a suitable height. Then, the old idlers are removed with a pry bar, and finally, the new idlers are lifted and installed in place by personnel.
[0004] When operating in open-air environments, there are usually no traction and fixing components such as frames above the conveyor belt, making it impossible to use tools such as chain hoists and wire ropes to stably support the conveyor belt. This results in limitations in the support operation of the conveyor belt, making it unsuitable for the spatial conditions of open-air sites, and thus affecting the efficiency of idler replacement. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a convenient replacement device for conveyor belt idlers, which solves the problem of difficulty in providing stable support for the conveyor belt due to the lack of traction components in open-air environments.

[0007] Fasteners;
[0008] A lifting member, one side of which is disposed on the fixing member;
[0009] A first support member is disposed on the side of the lifting member away from the fixing member;
[0010] The second support member is detachably mounted on the first support member to support the side of the conveyor belt.
[0011] In one feasible implementation, the fastener includes:
[0012] First fixed part;
[0013] An inclined portion, one end of which is connected to the first fixed portion;
[0014] The second fixing part is connected to the end of the inclined part away from the first fixing part, and one side of the lifting member is disposed on the second fixing part.
[0015] In one feasible embodiment, the fastener further includes a third fixing part, which is disposed on one side of the fastener and has a threaded hole, on which a screw is threadedly connected.

[0017] In one feasible implementation, the second support member includes:
[0018] A sleeve, which is slidably fitted onto the outside of the first support member;
[0019] A support rod is inclinedly mounted on the sleeve.
[0020] In one feasible implementation, the angle between the support rod and the sleeve is 30°-60°.
[0021] In one feasible implementation, the first support member is made of square steel, and the sleeve has a square hole, the inner circumference of which matches the outer circumference of the first support member.
[0022] In one feasible implementation, a traction member is detachably mounted on the first support member.
[0023] In one feasible implementation, the first support member is provided with at least one hook, and the traction member is attached to the hook.
[0024] In one feasible implementation, the number of hooks is two, and the two hooks are disposed on opposite sides of the first support member.
[0025] This utility model provides a convenient replacement device for conveyor belt idlers, which has the following advantages:
[0026] This invention fixes the fixing component to the idler frame. By operating the lifting component, the first support component supports the bottom of the conveyor belt, facilitating the replacement of the bottom idler. When replacing the side idler, the support rod is set on the first support component.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] In the following description, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more, and "at least one" means one or more.
[0037] Furthermore, in this application, directional terms such as "upper," "lower," "inner," and "outer" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.
[0038] To facilitate understanding of the technical solutions of the embodiments of this application by those skilled in the art, the technical terms involved in the embodiments of this application will be explained below.
[0039] A self-locking screw crane is a device that supports heavy objects based on the principle of screw transmission. Its core function is to stably lift and fix the position of heavy objects. Structurally, it typically includes a screw, a nut, a support base, and an operating handle. During operation, the screw is rotated by manually turning the handle, causing the nut to move along the screw's axis. This moves the upper load-bearing component upward and lifts the heavy object. Once the required support height is reached, the self-locking characteristic of the screw transmission prevents the screw and nut from rotating relative to each other due to the friction between the threads, keeping the heavy object stably held at the specified height without the need for additional fixing.
[0040] Currently, when replacing idlers, tools such as chain hoists and wire ropes are needed to first support the conveyor belt to counteract its weight and tension, separating the belt from the idlers to a suitable height. Then, a pry bar is used to remove the old idler, and finally, personnel lift and install the new idler. In open-air environments, there are usually no traction or fixing components above the conveyor belt, making it impossible to use chain hoists and wire ropes for stable support. This limits the support operation and makes it unsuitable for open-air spaces, thus affecting the efficiency of idler replacement.
[0041] In addition, the conveyor belt needs to maintain sufficient tension during normal operation and also has its own weight. When changing idlers, personnel need to overcome these two forces to achieve effective separation of the conveyor belt and the idlers. Therefore, it is difficult for a single person to support the conveyor belt, and it often requires the cooperation of multiple people, which means there are requirements for the number of personnel. The idlers that support the conveyor belt are usually bottom idlers and side idlers set on both sides of the bottom idlers. There are various types of idlers and large differences in weight. When the weight of the bottom idler is heavy, it is difficult for personnel to lift it, making it more strenuous to change the bottom idler.
[0042] This utility model provides a convenient replacement device for conveyor belt idlers, which solves the problems of difficulty in providing stable support for the conveyor belt due to the lack of traction components in open-air environments, as well as the current problems of requiring multiple people to work together to replace idlers and the laboriousness of replacing heavy bottom idlers.
[0043] The embodiments of this application will now be described with reference to the accompanying drawings.
[0044] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the conveyor belt, bottom idler, and side idler in the prior art, such as... Figure 1 As shown, the bottom idler 10 is rotatably mounted at the middle position of the top of the idler frame 7, and two side idlers 11 are rotatably mounted on the idler frame 7 and located on both sides of the bottom idler 10. The conveyor belt 9 is mounted on the bottom idler 10 and the two side idlers 11. The bottom idler 10 supports the bottom 902 of the conveyor belt, and the side idlers 11 support the side 901 of the conveyor belt. When the conveyor belt 9 moves, it drives the bottom idler 10 and the side idlers 11 to rotate.
[0045] Please see Figure 2 , Figure 2 The diagram shows a top view of the roller frame, the first connecting rod, and the second connecting rod in the prior art. Figure 2 As shown, two first connecting rods 701 can be installed on the roller frame 7, and a second connecting rod 702 can be installed on the two first connecting rods 701.
[0046] This application provides a convenient replacement device for conveyor belt idlers. Please refer to [link / reference]. Figure 3 , Figure 3 A three-dimensional structural diagram of a convenient replacement device for conveyor belt idlers provided in an embodiment of this utility model is shown below. Figure 3 As shown, the device includes: a fixing member 1, a lifting member 2, a first support member 3, and a second support member 4; the fixing member 1 is used to connect and fix with the idler frame 7 to provide a support base for the lifting member 2, the first support member 3, and the second support member 4; the lifting member 2 is used to drive the first support member 3 and the second support member 4 to move closer to or further away from the conveyor belt 9; when the bottom idler 10 is replaced, the lifting member 2 drives the first support member 3 to move to lift the bottom 902 of the conveyor belt; when the side idler 11 is replaced, the second support member 4 is placed on the first support member 3; when the lifting member 2 drives the first support member 3 to move, the first support member 3 drives the second support member 4 to move, so that the first support member 3 lifts and supports the bottom 902 of the conveyor belt, and the second support member 4 lifts and supports the side 901 of the conveyor belt.
[0047] Please see Figure 4 , Figure 4A three-dimensional structural diagram of a fastener for a convenient replacement device for conveyor belt idlers provided in an embodiment of this utility model is shown below. Figure 4 As shown, the fastener 1 includes: a first fixing part 101, an inclined part 102, and a second fixing part 103.
[0048] The first fixing part 101, the inclined part 102, and the second fixing part 103 can all be steel plates. The steel plate structure can ensure the strength of the device and ensure the stability of the support. One end of the inclined part 102 is connected to the first fixing part 101, and the second fixing part 103 is connected to the end of the inclined part 102 away from the first fixing part 101. The first fixing part 101 and the inclined part 102, and the inclined part 102 and the second fixing part 103 can all be fixed by welding. More specifically, the first fixing part 101 and the inclined part 102 can both be welded to round steel to achieve connection, thereby ensuring the integrity and stability of the fixing part 1.
[0049] In some embodiments, the angle between the inclined portion 102 and the second fixed portion 103 is 0°-90°. For example, the angle between the inclined portion 102 and the second fixed portion 103 can be 60°. When the angle is set to 60°, the high strength characteristics of the steel plate can enable the inclined portion 102 to form a stable support structure for the second fixed portion 103, avoiding deformation of the fixing member 1 caused by the gravity component of the conveyor belt 9 or the impact of materials.
[0050] Please see Figure 5 , Figure 5 A schematic diagram of the third fixing part of a convenient replacement device for conveyor belt idlers provided in an embodiment of this utility model is shown below. Figure 2 , Figure 4 and Figure 5As shown, the fixing member 1 also includes a third fixing part 104, which is disposed on one side of the fixing member 1. Specifically, the third fixing part 104 can be a right-angled steel plate, which can be disposed on the first fixing part 101 and on the same side as the second fixing part 103. A threaded hole 1041 is provided on the third fixing part 104, and a screw 8 is threaded into the threaded hole 1041. Specifically, the threaded hole 1041 is located on the side of the right-angled steel plate opposite to the first fixing part 101. When the first fixing part 101 is installed on the roller frame 7, the first fixing part 101 and the third fixing part 104 are engaged on the second connecting rod 702. The inner circumference of the groove formed by the first fixing part 101 and the third fixing part 104 matches the outer circumference of the second connecting rod 702. When fixing, the screw 8 is screwed into the threaded hole 1041 so that the end of the screw 8 abuts against the second connecting rod 702, thereby fixing the fixing part 1 on the roller frame 7. The matching of the inner circumference of the groove formed by the first fixing part 101 and the third fixing part 104 with the outer circumference of the second connecting rod 702, and the fastening of the fixing part 1 and the roller frame 7 by the screw 8, can effectively ensure the stability of the device and prevent the fixing part 1 from shifting relative to the roller frame 7 during use.
[0051] Please refer to this again. Figure 3 One side of the lifting member 2 is set on the fixing member 1, and the first support member 3 is set on the side of the lifting member 2 away from the fixing member 1. Specifically, one side of the lifting member 2 is set on the second fixing part 103. The lifting member 2 can be a self-locking screw crane. When the operator screws the screw of the self-locking screw crane, the self-locking screw crane can be moved to drive the first support member 3 to move towards the conveyor belt 9 or away from the conveyor belt 9.
[0052] The second support member 4 is detachably mounted on the first support member 3 to support the side 901 of the conveyor belt. When the bottom idler roller 10 needs to be replaced and the bottom 902 of the conveyor belt needs to be lifted for support, the second support member 4 is not mounted on the first support member 3. When the lifting member 2 is operated, the lifting member 2 drives the first support member 3 to move closer to the bottom 902 of the conveyor belt until the bottom 902 of the conveyor belt is lifted, and then the bottom idler roller 10 is replaced. When the side idler roller 11 needs to be replaced and the bottom 902 and side 901 of the conveyor belt need to be lifted for support, the second support member 4 is mounted on the first support member 3. When the lifting member 2 is operated, the second support member 4 is mounted on the first support member 3. When the lifting component 2 moves, it drives the first support component 3 to move towards the bottom 902 of the conveyor belt. When the first support component 3 moves, it simultaneously drives the second support component 4 to move towards the side 901 of the conveyor belt, until the first support component 3 lifts and supports the bottom 902 of the conveyor belt, and the second support component 4 lifts and supports the side 901 of the conveyor belt. Then, the personnel can replace the side idler roller 11. When using this device, it is only necessary to fix the fixing component 1 on the idler frame 7 and then operate the lifting component 2 to replace the idler roller. It does not require the traction fixing component above the conveyor belt 9. Therefore, it can be used in open-air environments where there is no frame or other traction fixing component, and it has good applicability.
[0053] Please see Figure 6 , Figure 6 A three-dimensional structural diagram of the second support member of a convenient replacement device for conveyor belt idlers provided in an embodiment of this utility model is shown below. Figure 3 and Figure 6 As shown, the second support member 4 includes a sleeve 401 and a support rod 402. The sleeve 401 is slidably sleeved on the outside of the first support member 3, and the support rod 402 is inclinedly disposed on the sleeve 401. The slidable connection between the sleeve 401 and the first support member 3 simplifies the installation and removal of the second support member 4 from the first support member 3. When the first support member 3 moves towards the conveyor belt 9, the first support member 3 drives the sleeve 401 to move towards the conveyor belt 9, and the sleeve 401 drives the second support member 4 to move synchronously, thereby causing the inclined support rod 402 to abut against the side 901 of the conveyor belt for support. After the rod 402 abuts against the side 901 of the conveyor belt, the conveyor belt 9 will generate a gravitational component force on the support rod 402 due to its own weight. This force is transmitted to the sleeve 401 along the inclined support rod 402, which counteracts the tendency of the sleeve 401 to slide outward along the first support member 3, thereby limiting the displacement of the sleeve 401 and preventing it from falling off. At the same time, although the sliding connection between the first support member 3 and the sleeve 401 simplifies the assembly and disassembly, the reverse force generated by the force on the support rod 402 just makes up for the lack of stability of the sliding connection, thus taking into account both convenience and reliability.
[0054] In some embodiments, the angle between the support rod 402 and the sleeve 401 is 30°-60°. More specifically, the angle between the support tube and the sleeve 401 can be 45°. This angle can avoid problems such as small contact area between the support rod 402 and the side of the conveyor belt 901, easy slippage of the conveyor belt 9 on the support rod 402, or insufficient lateral pressure.
[0055] In some embodiments, the first support member 3 is made of square steel, and a square hole 4011 is provided on the sleeve 401. The inner circumference of the square hole 4011 matches the outer circumference of the first support member 3, which can prevent the sleeve 401 from rotating relative to the first support member 3, ensure the stability of the support rod 402 when it abuts against the conveyor belt 9, further reduce the risk of the sleeve 401 falling off and enhance the overall support rigidity of the structure.
[0056] Please refer to Figures 1-4 The fixing member 1 can be set perpendicularly to the first support member 3 and the support rod 402. Since the second connecting rod 702 is set parallel to the idler frame 7, when the fixing member 1 is installed on the second connecting rod 702, that is, the fixing member 1 is set perpendicular to the second connecting rod 702 (the length direction of the fixing member 1 is perpendicular to the length direction of the second connecting rod 702), the first support member 3 and the second connecting rod 702 can be set parallel to each other, that is, the first support member 3 is set parallel to the first idler, so that the first support member 3 and the second support member 402 are perpendicular to the conveying direction of the conveyor belt 9, so that the lifting member 2 drives the first support member 3 and the support rod 402 to provide a better support effect for the conveyor belt 9.
[0057] Please refer to this again. Figure 3 In some embodiments, a traction member 5 is detachably provided on the first support member 3. For example, the traction member 5 can be a chain. When the bottom idler roller 10 is heavy and needs to be replaced, the traction member 5 can be wrapped around the new idler roller, and the operator can operate the lifting member 2 to lift the new idler roller while the first support member 3 is against the bottom 902 of the conveyor belt. This eliminates the need for personnel to hold the new idler roller for a long time. The old idler roller can be disassembled and the new idler roller can be installed, which saves labor and is convenient for installation.
[0058] In some embodiments, the first support member 3 is provided with at least one hook 6, and the traction member 5 is hung on the hook 6. There are two hooks 6, which are set on opposite sides of the first support member 3, so that the traction member 5 is more stably hung on the first support member 3. When replacing the heavier bottom idler roller 10, the traction member 5 can be evenly wound and lifted by the hooks 6 on both sides, avoiding the traction member 5 from shifting and causing the new idler roller to tilt. This further ensures that the stability of the new idler roller is improved at the same time when the first support member 3 hits the conveyor belt 9, which not only saves the physical exertion of personnel lifting for a long time, but also makes the installation of the idler roller more convenient and efficient.
[0059] This device fixes the fixing component 1 on the idler frame 7. By operating the lifting component 2, the first support component 3 supports the bottom 902 of the conveyor belt, which facilitates the replacement of the bottom idler 10. When replacing the side idler 11, the support rod 402 is set on the first support component 3. When the operator operates the lifting component 2, the first support component 3 can support the bottom 902 of the conveyor belt and the second support component 4 can support the side 901 of the conveyor belt, which facilitates the replacement of the side idler 11. This device does not require the use of traction and fixing components such as the frame above the conveyor belt 9, and can replace idlers even in open-air conditions. It has good applicability and improves the efficiency of replacing idlers.
[0060] Meanwhile, the installation of the fixing component 1 and the operation of the lifting component 2 can be completed by a single person, which is simple to operate and does not require multiple people to work together. When the bottom idler roller 10 is heavy, the new idler roller can be wound around the traction component 5. During the process of supporting the bottom 902 of the conveyor belt, the new idler roller can be lifted without the need for personnel to lift the bottom idler roller 10 for a long time, thus reducing the physical exertion of personnel.
[0061] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
