Description

Technical Field

[0001] This utility model belongs to the field of coal mine winch equipment maintenance technology, and in particular relates to a tooling for underground coal mine winch maintenance. Background Technology

[0002] Currently, belt conveyors used in underground coal mines typically employ winches to tension the conveyor belt. However, when winch components, such as the winch motor, coupling, or reducer, malfunction and require repair, the wire rope on the winch is already taut over the conveyor belt. Immediately disassembling and repairing the winch can cause the winch drum to lose its restraint, leading to rapid rotation under the belt tension, resulting in belt slippage or even belt slippage, and potentially causing a safety accident. Summary of the Invention

[0003] The purpose of this utility model embodiment is to provide a tooling for maintaining winches in coal mines, aiming to solve the technical problems existing in the prior art mentioned in the background art.

[0004] This utility model embodiment is implemented as follows: a tooling for maintaining a winch in a coal mine, characterized in that the tooling includes a crossbeam connected to the winch frame, a fixed seat fixedly connected to the crossbeam, an arc-shaped fixed plate connected to the fixed seat via a fixed pin, an arc-shaped connecting plate fixedly connected to the arc-shaped fixed plate, and a plurality of through holes provided on the arc-shaped connecting plate, the through holes being positioned opposite to through holes provided on the side plate of the drum, so that the arc-shaped connecting plate and the side plate of the drum can be connected via fixed pins to restrict the rotation of the drum.

[0005] Preferably, there are two through holes on the arc-shaped connecting plate, located at both ends of the arc-shaped connecting plate, and the positions of the through holes on the arc-shaped connecting plate are distributed about the rotation center of the drum.

[0006] More preferably, the arc length between the two through holes on the arc connecting plate is an integer multiple of the arc length between two adjacent through holes on the side plate of the drum.

[0007] More preferably, the arc-shaped fixing plate is provided with several rows of screw holes arranged in an arc, and the arc-shaped connecting plate is also provided with several rows of screw holes arranged in an arc, so that the arc-shaped fixing plate and the arc-shaped connecting plate can be connected by bolts and screw holes.

[0008] More preferably, the screw holes are distributed around the rotation center of the drum.

[0009] The beneficial effects of this utility model are as follows: The drum is connected to the arc-shaped connecting plate, which is then connected and fixed to the arc-shaped fixing plate. The arc-shaped fixing plate is connected to the fixing seat, which in turn is fixed to the crossbeam. This forms a stable, approximately triangular structure, thus securing the drum. After fixing, when repairing or disassembling components such as the reducer, brake, or coupling, the drum will not rotate, ensuring that the wire rope wound on the drum will not loosen and the belt will not slip.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] It is understood that the terms “first,” “second,” etc., used in this application may be used herein to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0018] like Figures 1-5As shown, in one embodiment, a tooling for maintaining a winch in a coal mine is proposed. The tooling includes a crossbeam 2 connected to the winch frame 10. A fixed seat 3 is fixedly connected to the crossbeam 2. An arc-shaped fixed plate 5 is connected to the fixed seat 3 via a fixed pin 6. An arc-shaped connecting plate 4 is fixedly connected to the arc-shaped fixed plate 5. The arc-shaped connecting plate 4 has several through holes, the positions of which are opposite to through holes formed on the side plate of the drum 1. This allows the arc-shaped connecting plate 4 and the side plate of the drum 1 to be connected via the fixed pin 6, thereby restricting the rotation of the drum 1.

[0019] In this embodiment of the invention, when winch accessories (such as winch motor 7, winch coupling 8, winch reducer 9, etc.) are damaged, drum 1 will stop at any position. At this time, the arc-shaped fixing plate 5 and the arc-shaped connecting plate 4 can be easily fastened with bolts. At this time, the arc-shaped connecting plate 4, the arc-shaped fixing plate 5, and the fixing seat 3 form a stable triangular structure due to the connection and fastening effect of the fixing pin 6, which can firmly fix drum 1 when it stops at any position. Then, the winch accessories can be disassembled and repaired. Since the drum is fixed, drum 1 will not rotate when repairing or disassembling components such as the reducer, brake, and coupling, thus ensuring that the wire rope wound on drum 1 will not loosen and the belt will not fly off.

[0020] It should be noted that the drum 1, winch motor 7, winch coupling 8, winch reducer 9, and winch frame 10 in the accompanying drawings of this utility model are all original winch components and are not structures that this utility model seeks to protect. They are only used for illustration and explanation for the sake of completeness of the technical solution description.

[0021] like Figure 2 As shown, in a preferred embodiment of this utility model, two through holes are formed on the arc-shaped connecting plate 4, located at both ends of the arc-shaped connecting plate 4. The positions of the through holes on the arc-shaped connecting plate 4 are distributed about the rotation center of the drum 1. More preferably, the arc length between the two through holes on the arc-shaped connecting plate 4 is an integer multiple of the arc length between two adjacent through holes on the side plate of the drum 1.

[0022] In this embodiment of the utility model, the positions of the through holes on the arc connecting plate 4 are distributed about the rotation center of the drum 1, and the arc length between two through holes on the arc connecting plate 4 is an integer multiple of the arc length between two adjacent through holes on the side plate of the drum 1. This ensures that the drum 1 and the arc connecting plate 4 can be connected by the fixed pin 6 at any position.

[0023] like Figure 4 and Figure 5As shown, in a preferred embodiment of this utility model, the arc-shaped fixing plate 5 is provided with several rows of screw holes arranged in an arc, and the arc-shaped connecting plate 4 is also provided with several rows of screw holes arranged in an arc. The arc-shaped fixing plate 5 and the arc-shaped connecting plate 4 are connected by bolts and screw holes. The screw holes are all distributed around the rotation center of the drum 1, and the screw holes on the arc-shaped fixing plate 5 are preferably oblong holes.

[0024] In this embodiment of the utility model, the purpose of providing screw holes on the arc fixing plate 5 and the arc connecting plate 4 is to facilitate the connection between the two. Here, the number of screw holes on the arc fixing plate 5 is preferably two rows, and the number of screw holes on the arc connecting plate 4 is preferably at least two rows. In this way, the arc fixing plate 5 can be connected to screw holes at different positions on the arc connecting plate 4 to improve the adaptability to the drum 1.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.

[0027] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
