Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of overhead crane fixed pulley inspection auxiliary devices, in particular to an overhead crane fixed pulley inspection special device. Background Art
[0002] During the operation of the overhead crane, the fixed pulley is an important component, and its normal operation is crucial to the stability and safety of the overhead crane. However, the traditional fixed pulley inspection method requires manual climbing to a high place for inspection, which has safety hazards and is inefficient. Therefore, it is necessary to design a device that can quickly and safely inspect the fixed pulley. Summary of the invention
[0003] The utility model aims to provide a special device for spot checking a fixed pulley of an overhead travelling crane, so as to solve the problems existing in the prior art.
[0004] The utility model solves the technical problem by adopting the technical solution of: a special device for checking the fixed pulley of an overhead crane, comprising a support rod, a handle welded on the top of the support rod, a pulley clamp welded obliquely on the bottom of the support rod, and a bolt clamp welded obliquely on the side wall of the support rod.
[0005] Furthermore, the pulley card is U-shaped, and the opening of the pulley card faces downward.
[0006] Furthermore, a slot is provided at one end of the bolt clamp, the shape of the slot matches the shape of the fixed pulley bolt, and one side of the slot is open and flared.
[0007] The utility model has the following beneficial effects:
[0008] 1. The utility model does not require climbing to a high place when inspecting the fixed pulley of the overhead crane, thereby reducing safety risks and improving inspection efficiency.
[0009] 2. The staff can stand in a safe position and hold a longer support rod for inspection, thus reducing safety risks.
[0010] 3. Check whether the pulley is shaking by the pulley card. The operation is simple and the inspection efficiency is improved.
[0011] 4. Check whether the bolts are loose by the bolt card and tighten them. It is easy to operate and further improves the inspection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the structure of the utility model.
[0013] Figure 2 This utility model Figure 1 Enlarged structural diagram at A in the middle.
[0014] Among them: 1. Support rod; 2. Handle; 3. Pulley clamp; 4. Bolt clamp; 5. Clamp slot. DETAILED DESCRIPTION
[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with specific embodiments and drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0016] like Figure 1-2 As shown, a special device for inspecting the fixed pulley of an overhead crane comprises a support rod 1, a handle 2 is welded on the top of the support rod 1, a pulley clamp 3 is welded obliquely on the bottom of the support rod 1, and a bolt clamp 4 is welded obliquely on the side wall of the support rod 1.
[0017] The pulley card 3 is U-shaped, with the opening of the pulley card 3 facing downward. The pulley card 3 is clamped on the pulley piece of the fixed pulley and shaken left and right to perform spot inspection of the pulley piece.
[0018] A slot 5 is provided at one end of the bolt clamp 4, and the shape of the slot 5 matches the shape of the fixed pulley bolt. One side of the slot 5 is open and flared. The bolt clamp 4 is clamped on the bolt of the fixed pulley, and the bolt is rotated to check whether it is loose.
[0019] The working principle of the utility model is:
[0020] When in use, hold the handle 2 and clamp the pulley clamp 3 on the pulley sheet of the fixed pulley, shake the utility model left and right, if the fixed pulley sheet shakes, it means that it needs to be repaired, otherwise it means that the fixed pulley is operating normally. After checking the pulley sheet, turn the utility model upside down, clamp the bolt clamp 4 on the bolt of the fixed pulley, and check whether it is loose by rotating the bolt. If the bolt is loose, you can use the utility model to tighten it, otherwise it means that it is operating normally.
[0021] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solution of the present invention shall fall within the scope of protection of the present invention.
[0022] The technology, shape and structure parts not described in detail in the present invention are all known technologies.
