Description

Technical Field

[0001] This utility model belongs to the field of cable trolley traveling wheel replacement technology, and in particular relates to a clamp for quickly replacing the traveling wheels of overhead crane cable trolleys. Background Technology

[0002] As a key component of the overhead crane system, the cable-hauling trolley is responsible for moving the flexible cable and ensuring its synchronous movement with the crane trolley mechanism, thereby achieving a continuous and stable power supply and signal transmission. A cable-hauling trolley typically has multiple traveling wheels symmetrically arranged on both sides of the I-beam track to ensure smooth movement along the track. However, with increasing service life, the outer edges and internal bearings of the traveling wheels inevitably wear down, affecting their support and movement functions, causing the traveling wheels to malfunction, and even triggering abnormal operation of the entire cable-hauling system.

[0003] Replacing the traveling wheels primarily relies on removing the bolts and nuts fixed to the trolley side plate. However, because the bolt heads are located inside the traveling wheel and face the I-beam rail, with a narrow gap in between, traditional tools are difficult to insert and securely fix the bolt heads. Therefore, when removing the nuts, the nuts and bolts often rotate synchronously, making the disassembly work extremely difficult. To solve this problem, maintenance personnel often need to take more complex procedures, such as first removing the trolley side plate on the side of the damaged traveling wheel, replacing the traveling wheel, and then restoring the side plate. This process is not only time-consuming and labor-intensive, but also prone to causing the trolley to detach from the rail, increasing operational risks, prolonging maintenance time, and affecting production efficiency. Utility Model Content

[0004] To address the problem in existing technology where the narrow gap between the traveling wheel and the I-beam rail makes it difficult to secure the bolt head, this invention aims to provide a clamp for quickly changing the traveling wheel of an overhead crane cable trolley. This clamp, by incorporating a bent portion, allows for more flexible insertion into the narrow gap between the traveling wheel and the I-beam rail, clamping the bolt head and preventing the nut and bolt from rotating synchronously, thus facilitating rapid wheel replacement.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A clamp for quickly changing the traveling wheel of a crane cable trolley, wherein the traveling wheel slides on an I-beam rail and is connected to the trolley by bolts; the head of the bolt is located between the traveling wheel and the I-beam rail, and the tail passes through the side plate of the traveling wheel and the trolley in sequence and is threadedly connected to a nut.

[0007] The clamp includes a clamping base and a clamping plate. The clamping base includes a hand-held part, a bending part, and a clamping part. The hand-held part and the clamping part are arranged parallel to each other, and the hand-held part and the clamping part are connected by the bending part. The bending part is a Z-shaped bend, which makes it easy for the clamp to extend into the gap between the traveling wheel and the I-beam rail.

[0008] Two spaced-apart clamping plates are mounted on the surface of the clamping part, and the two clamping plates are used to clamp the bolt head.

[0009] Furthermore, the handheld part is equipped with a non-slip rubber sleeve.

[0010] Furthermore, the bent portion is formed by connecting two arcs with opposite bending directions, allowing the clamp to more flexibly extend into the narrow gap between the traveling wheel and the I-beam rail.

[0011] Furthermore, the clamping base is a one-piece molded design.

[0012] Furthermore, the clamping seat has a length of 300mm and a width of 30mm.

[0013] Furthermore, the distance between the two clamping plates is 25mm.

[0014] Furthermore, the clamping plate is provided with anti-slip texture.

[0015] Furthermore, the clamping plate is provided with an anti-slip pad.

[0016] Furthermore, the clamping plate is bolted to the clamping seat.

[0017] Compared with the prior art, the clamp for quick replacement of overhead crane cable trolley wheels described in this utility model has the following advantages:

[0018] The clamp for quickly changing the traveling wheels of an overhead crane cable trolley, as described in this utility model, features a Z-shaped bend on the clamping seat. This allows the clamp to more flexibly extend into the narrow gap between the traveling wheel and the I-beam rail, improving its applicability, significantly shortening operation time, and increasing work efficiency. Regarding clamping and fixing, two clamping plates precisely clamp the bolt heads that secure the traveling wheels, providing a uniform and stable clamping force. When the operator uses this clamp to hold the bolt heads and attempt to remove the nuts, the bolt heads are firmly fixed due to the secure clamping plates, preventing synchronous rotation with the nuts. This ensures a smooth disassembly process and avoids operational difficulties and potential safety hazards caused by synchronous rotation of the bolts and nuts.

[0019] Using this clamp, the replacement of the traveling wheels can be completed independently without disassembling the side support plate of the trolley. The operator simply inserts the clamping seat into the gap between the traveling wheel and the I-beam rail, clamps the head of the fixing bolt using the clamping plate, and then proceeds with the normal disassembly process. Throughout the entire process, the clamp maintains a stable clamping position, effectively preventing the trolley from falling off the rail, greatly improving the safety and convenience of the operation.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 2 As shown, a clamp for quickly changing the traveling wheel of a crane cable trolley is provided. The traveling wheel slides on an I-beam rail and is connected to the trolley by bolts. The head of the bolt is located between the traveling wheel and the I-beam rail, and the tail passes through the side plate of the traveling wheel and the trolley in sequence and is threadedly connected to a nut.

[0030] The clamp includes a clamping base 1 and a clamping plate 2. The clamping base 1 includes a hand-held part 11, a bending part 12 and a clamping part 13. The hand-held part 11 and the clamping part 13 are arranged in parallel and are connected by the bending part 12. The bending part 12 is a Z-shaped bend, which facilitates the clamp to extend into the gap between the traveling wheel and the I-beam rail.

[0031] Two spaced clamping plates 2 are mounted on the surface of the clamping part 13, and the two clamping plates 2 are used to clamp the bolt head.

[0032] In a preferred embodiment of this utility model, the handgrip 11 is provided with an anti-slip rubber sleeve to increase the friction between the hand and the handgrip and prevent slippage during operation. The handgrip 11 is designed in an ergonomic shape such as cylindrical or wavy to ensure comfortable grip for the operator and reduce hand fatigue during prolonged use.

[0033] In a preferred embodiment of this utility model, the bending portion 12 is formed by connecting two arcs with opposite bending directions, which allows the clamp to more flexibly extend into the narrow gap between the traveling wheel and the I-beam rail, and adapt to gaps of different shapes and sizes, thereby expanding the range of applications of the clamp and improving its versatility.

[0034] In a preferred embodiment of this utility model, the clamping base 1 is a one-piece molded design, making the overall structure of the clamping base more stable and reliable. When subjected to the force applied by the clamping bolt head and the operator, it can maintain good shape and performance and is not easily damaged. Specifically, the clamping base 1 has a length of 300mm and a width of 30mm.

[0035] In a preferred embodiment of this invention, the distance between the two clamping plates 2 is 25mm. The distance between the clamping plates 2 can be designed according to the actual size of the bolt head.

[0036] In a preferred embodiment of this invention, the clamping plate 2 is provided with anti-slip texture. Specifically, during the operation of quickly changing the traveling wheels of the overhead crane cable trolley, the main function of the clamping plate 2 is to clamp the bolt head that fixes the traveling wheel. The anti-slip texture significantly increases the coefficient of friction between the clamping plate 2 and the bolt head. When the operator uses a clamp to hold the bolt head and attempts to remove the nut, the presence of the anti-slip texture increases the friction between the clamping plate 2 and the bolt head, allowing the clamping plate 2 to more firmly "grip" the bolt head and prevent relative slippage of the bolt head during nut removal.

[0037] In a preferred embodiment of this invention, an anti-slip pad is provided on the clamping plate 2. Specifically, the anti-slip pad generates significant friction when in contact with the bolt head, effectively preventing the bolt head from slipping during nut removal. Different models and specifications of overhead crane cable pulleys may use bolts of different sizes and shapes. The anti-slip pad design allows the clamping plate to better adapt to various bolt heads, improving the versatility of the clamp and eliminating the need for specialized clamps for different bolt specifications, thus reducing operating costs.

[0038] In a preferred embodiment of this invention, the clamping plate 2 is bolted to the clamping seat 1. Specifically, when the clamping plate 2 becomes worn, damaged, or needs to be replaced with a clamping plate of a different specification, the bolted connection allows for easy removal of the old clamping plate 2 and installation of the new clamping plate. This detachability makes the maintenance and repair of the clamp easier, reducing maintenance and time costs.

[0039] The clamping plate 2 and the clamping seat 1 are also connected by welding. During the replacement of the overhead crane cable trolley traveling wheel, the clamping plate needs to withstand a large external force and torque. The welding connection can ensure that the clamping plate and the clamping seat will not loosen or separate, thus ensuring the stability and reliability of the clamping.

[0040] The working principle of a clamp for quickly changing the traveling wheels of an overhead crane cable trolley:

[0041] The clamping part 13 of the clamping seat 1 is inserted into the gap between the traveling wheel and the I-beam rail, so that the two clamping plates 2 clamp the bolt heads used to fix the traveling wheel. The worker then removes the nut used to fix the traveling wheel, thereby replacing the traveling wheel. The two clamping plates 2 clamping the bolt heads can prevent the bolt and nut from rotating synchronously during the nut removal process. Using this clamp to replace the traveling wheel does not require disassembling the side support plate of the trolley, so no additional tools are needed to fix the entire trolley, thus preventing the trolley from falling off the rail.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
