Description

Technical Field

[0001] This utility model belongs to the field of belt conveyor idler technology, and in particular relates to an auxiliary device for disassembling belt conveyor idlers. Background Technology

[0002] Belt conveyors are industrial devices used to transport materials, which are conveyed by rubber belts mounted on the conveyor. To ensure that the rubber belts have sufficient load-bearing capacity to support the materials during transport, multiple idler rollers are often installed on the conveyor frame along the length of the belt.

[0003] Most current idler structures are V-shaped, consisting of side idlers with two upward-facing sides and a horizontally positioned idler in the middle. This idler structure supports the edges of the belt inwards, creating a V-shape and preventing material from spilling from the belt edges.

[0004] However, since the idlers are constantly supported by the belt, most of the weight of the belt and the material rests on the idlers. As a result, the idlers are prone to damage over time, such as excessive wear and loosening. Because the idlers are supported by the belt, any damage to the idlers must be repaired immediately; otherwise, it will seriously affect the stability of the belt transmission and easily lead to belt misalignment and other malfunctions.

[0005] Therefore, in actual operation, idlers that malfunction need to be repaired or replaced. However, since the load of the idler is supported at the bottom of the belt, the belt obstructs the space during the repair or replacement process, making it difficult to operate the idler.

[0006] Therefore, to facilitate the operation of idler rollers, existing technologies use auxiliary tools such as support rods to lift the belt from both sides, detaching it from the idler roller and exposing more space for easier operation. However, this method has several drawbacks: First, the support rods require simultaneous operation from both sides to pry the belt up, demanding a high degree of coordination. Second, the lifting process often requires multiple adjustments to the lifting height to ensure sufficient exposure, making it cumbersome. Third, if the support rods detach during operation, the belt will immediately fall, potentially injuring the operators, thus posing a safety risk. Most importantly, the operation itself is extremely time-consuming. Utility Model Content

[0007] Based on the above background, the purpose of this utility model is to provide an auxiliary device for disassembling belt conveyor rollers.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A belt conveyor idler removal auxiliary device includes a belt lifting mechanism for lifting the belt.

[0010] The belt lifting mechanism includes a fixed bracket, and two ends of the fixed bracket are respectively hinged to a side-pushing structure for pushing the belt to the side; the side-pushing structure includes a side-pushing bracket, and the side-pushing bracket is hinged to an adjusting bracket, which is adjustablely mounted on the fixed bracket.

[0011] The outer end of the adjusting bracket is hinged to a support structure for a pusher side support.

[0012] The belt lifting mechanism also includes a lifting structure mounted on a fixed bracket for vertically lifting the belt.

[0013] Preferably, the fixed bracket has upwardly protruding bosses welded to both ends;

[0014] The adjusting bracket is mounted on the boss via a sliding adjusting structure.

[0015] Preferably, the sliding adjustment structure includes a pair of sliding adjustment screws welded and fixedly mounted on the adjustment bracket;

[0016] The sliding adjusting screw is slidably connected to the boss;

[0017] The sliding adjusting screw is threaded with a pair of locking nuts that lock onto both sides of the boss.

[0018] Preferably, the side push bracket has a pivot opening;

[0019] Several support shafts are rotatably connected inside the shaft opening, and the top surface of the support shaft protrudes from the top surface of the side push bracket.

[0020] Preferably, the side-push structure includes an electric push rod hinged to the outer end of the adjusting bracket;

[0021] The pushing end of the electric push rod is hinged to the bottom outer end of the side push bracket.

[0022] Preferably, a hinge bracket is fixedly connected to the bottom outer end of the side push bracket. The hinge bracket includes a bracket seat fixedly installed on the side push bracket, and a protruding hinge part is welded on the bracket seat.

[0023] A pin is fixedly connected to the hinge, and a hinge sleeve hinged to the pin is fixedly connected to the pushing end of the electric push rod.

[0024] Preferably, the support structure includes a support hydraulic cylinder fixedly installed at the bottom of the fixed bracket, and a support rod is fixedly connected to the piston rod of the support hydraulic cylinder, and the support rod is slidably connected to the center of the fixed bracket;

[0025] A horizontally arranged top beam is detachably installed on the top of the support rod.

[0026] Preferably, a cylinder support bracket is fixedly installed at the bottom of the cylinder barrel of the hydraulic cylinder, and support screws are threaded to both ends of the top of the cylinder support bracket, with the support screws threaded to the bottom of the fixed bracket.

[0027] Preferably, the bottom ends of the fixed bracket are detachably mounted with support brackets.

[0028] Preferably, the support bracket includes a support column, and a base is welded to the bottom of the support column;

[0029] The top of the support column is threaded with a height-adjustable support screw, and the bottom of the fixed bracket is fixedly connected with a screw mounting seat that mates with the support screw.

[0030] This utility model has the following beneficial effects:

[0031] 1. During operation, the operator inserts a fixing bracket into the gap between the belt and the conveyor frame at the front or rear end of the idler roller that needs maintenance. The fixing bracket spans both sides of the conveyor frame. Then, the belt is lifted vertically by the lifting structure. During the lifting process of the V-shaped belt, the belt edge extends to both sides. At this time, the side push brackets on both sides further push the belt edge towards the center of the belt, thereby raising the belt and bending the belt edge inward. Since the belt is made of rubber, the idler roller position is fully exposed after being raised, allowing the operator to easily maintain and disassemble the idler roller.

[0032] This method not only enables the belt to be lifted up in a simple and easy way during idler maintenance and disassembly, but also keeps the belt in a stable position after being lifted up, thus greatly improving the safety of the operation and increasing the efficiency of idler disassembly and maintenance.

[0033] 2. The distance between the side push brackets and the belt can be adjusted by a sliding adjustment structure, ensuring that the two sides of the belt can be fully supported on the side push brackets during the upward process.

[0034] 3. A pivot opening is provided on the side push bracket; according to the existing rotational connection method, several support pivots are rotatably connected in the pivot opening, and the top surface of the support pivot protrudes from the top surface of the side push bracket.

[0035] During the side-pushing of the belt via the support shaft, the bottom edge of the belt is supported on the support shaft, and rolling friction displacement occurs between the belt and the support shaft. This method protects the belt and reduces the resistance of pushing the belt sideways. Attached Figure Description

[0046] Example 1

[0047] like Figure 1-5 As shown, an auxiliary device for disassembling a conveyor belt idler includes a belt lifting mechanism. The belt lifting mechanism lifts the belt portion supported at the top of the idler during disassembly and maintenance, thereby exposing sufficient operating space for easier operation.

[0048] Specifically, the belt-lifting mechanism includes a fixed bracket 1, with side-pushing structures hinged to its left and right ends for pushing the belt to the side. Each side-pushing structure includes a side-pushing bracket 32, with an adjusting bracket 3 hinged to it (the lower end of the side-pushing bracket 32 ​​has a hinged interface, and the adjusting bracket 3 is connected to the hinged interface via a pin, allowing the side-pushing bracket 32 ​​to be hinged and rotated). The adjusting bracket 3 is adjustablely mounted on the fixed bracket 1; a support structure for pushing the side-pushing bracket 32 ​​is hinged to its outer end.

[0049] Meanwhile, the belt lifting mechanism also includes a lifting structure mounted on the fixed bracket 1 for vertically lifting the belt.

[0050] During operation, the operator inserts the fixing bracket 1 into the gap between the belt and the conveyor frame at the front or rear end of the idler roller that needs maintenance, and places the fixing bracket 1 across both sides of the conveyor frame. (In actual operation, in order to insert the fixing bracket 1 smoothly, the entire device can be inserted horizontally, adjusted, and then flipped to the normal position to avoid obstruction by the side push brackets 32 on both sides).

[0051] The belt is then lifted vertically using a lifting structure. During the lifting process of the V-shaped belt, the belt edge extends to both sides. At this time, the side push brackets 32 on both sides further push the belt edge towards the center of the belt, thereby raising the belt and bending the belt edge inward. Since the belt is made of rubber, the idler roller position is fully exposed after being raised, allowing the operator to easily maintain and disassemble the idler roller.

[0052] This method not only enables the belt to be lifted up in a simple and easy way during idler maintenance and disassembly, but also keeps the belt in a stable position after being lifted up, thus greatly improving the safety of the operation and increasing the efficiency of idler disassembly and maintenance.

[0053] Example 2

[0054] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, the front and rear ends of the top of the fixed bracket 1 are respectively welded with upward protruding bosses; the adjusting bracket 3 is installed on the bosses through a sliding adjustment structure.

[0055] The sliding adjustment structure includes a pair of sliding adjustment screws 31 welded and fixedly mounted on the adjustment bracket 3; the sliding adjustment screws 31 are slidably connected to the boss; and a pair of locking nuts 311 are threadedly connected to the sliding adjustment screws 31 and locked on both sides of the boss.

[0056] The distance between the side push brackets 32 and the belt can be adjusted by a sliding adjustment structure, ensuring that the two sides of the belt can be fully supported on the side push brackets 32 during the upward process. The adjustment method is as follows:

[0057] If it is necessary to increase the length of the support between the side push bracket 32 ​​and the belt, loosen the locking nut 311, push the side push bracket 32-adjusting bracket 3 inward, and then lock the locking nut 311 back into position.

[0058] During the process of the side push brackets 32 pushing the edge of the belt inward, in order to reduce the wear on the belt and reduce the resistance generated by pushing the belt, the belt is pushed by rolling friction (the belt and the side push brackets 32 slide relative to each other during the pushing process).

[0059] Specifically, the side push bracket 32 ​​has a pivot opening; according to the existing rotational connection method, a number of support pivots 321 are rotatably connected in the pivot opening, and the top surface of the support pivots 321 protrudes from the top surface of the side push bracket 32.

[0060] During the side-pushing of the belt via the support shaft 321, the bottom edge of the belt is supported on the support shaft 321 and undergoes rolling friction displacement with the support shaft 321. This method protects the belt and reduces the resistance of the side-pushing belt.

[0061] The aforementioned side-push structure includes an electric push rod 33 hinged to the outer end of the adjusting bracket 3; the pushing end of the electric push rod 33 is hinged to the bottom outer end of the side-push bracket 32.

[0062] Specifically, a hinge bracket 322 is fixedly connected to the bottom outer end of the side push bracket 32. The hinge bracket 322 includes a bracket seat fixedly installed on the side push bracket 32, and a protruding hinge part is welded on the bracket seat. A pin is fixedly connected to the hinge part, and correspondingly, a hinge sleeve hinged to the pin is fixedly connected to the pushing end of the electric push rod 33.

[0063] The electric push rod 33 mentioned above is a conventional electric telescopic rod disclosed in the prior art. Since the pushing force of the belt from the side to bend the belt towards the center does not require a very large pushing force, the edge of the belt can be pushed by the electric push rod 33.

[0064] Example 3

[0065] like Figure 1-5 As shown, this embodiment, based on the structure of embodiment 2, includes a support hydraulic cylinder 21 fixedly installed at the bottom of the fixed bracket 1. The reason for using the support hydraulic cylinder 21 to lift the belt is that the resistance to lifting the belt during the lifting process is mainly in the vertical direction. Furthermore, considering that in actual production, once the conveyor belt is in operation and needs to be stopped to replace the idlers, it is subjected not only to the resistance load of the belt but also to the weight load of the material on the belt, a hydraulic cylinder with higher pushing force is used as the lifting structure to lift the belt. In actual operation, especially for older conveyor belts, it is often necessary to stop for maintenance and replacement of idlers during operation. Therefore, considering all factors, the support hydraulic cylinder 21 is used to lift the belt.

[0066] A support rod 23 is fixedly connected to the piston rod of the hydraulic cylinder 21, and the support rod 23 is slidably connected to the center of the fixed bracket 1 (at the same time, the piston rod is slidably connected to the fixed bracket 1).

[0067] The top of the aforementioned support rod 23 is detachably fitted with a horizontally arranged top beam rod 24 (specifically, a threaded rod is welded to the center of the bottom of the top beam rod 24, and the threaded rod is connected to the top of the support rod). The top beam rod 24 provides horizontal support in the width direction of the belt.

[0068] The fixing method of the hydraulic cylinder 21 is as follows:

[0069] A cylinder support bracket is fixedly installed at the bottom of the cylinder barrel of the hydraulic cylinder 21. Support screws 22 are threaded to both ends of the top of the cylinder support bracket. The support screws 22 are threaded to the bottom of the fixed bracket 1 (this method enables the detachable installation of the hydraulic cylinder 21; specifically, a screw is welded to the bottom of the cylinder barrel of the hydraulic cylinder 21, and a through-hole for the screw is opened in the center of the cylinder support bracket; the screw passes through the through-hole and is then tightened with a nut). During operation, the strong supporting force of the hydraulic cylinder 21 lifts the belt of the conveyor belt idler. During the lifting process, the side-push bracket 32 ​​continuously pushes the edge of the belt towards the center, fully exposing the idler structure that needs to be disassembled.

[0070] Example 4

[0071] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 2, support brackets are detachably installed at both ends of the bottom of the fixed bracket 1 (the support brackets are in a separated state when the fixed bracket 1 is inserted into the gap between the belt and the frame). After the fixed bracket 1 is adjusted to a suitable position (near the location of the idler roller), the support brackets are reinstalled onto the fixed bracket 1.

[0072] Specifically, the support bracket includes a support column 4, the bottom of which is welded with a base; the top of the support column is threaded with a height-adjustable support screw 41 (the upper end of the support column 41 has a threaded groove of a certain depth), and the bottom of the fixed bracket 1 is fixedly connected with a screw mounting seat 11 that cooperates with the support screw 41 (the bottom of the screw mounting seat 11 has a threaded groove).

[0073] In actual operation, to facilitate the tightening of the support screw 41, a nut is welded to the upper end of the support screw. The hexagonal structure of the nut makes it easy for a wrench to be inserted. During operation, the wrench is inserted into the welded nut, and as the support screw 41 is raised, it is threaded onto the screw mounting seat 11 at the bottom of the fixed bracket 1, thus supporting the entire device on the ground.

[0074] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
