Technical Field

[0001] This utility model relates to the field of rope deployment and retraction, and in particular to a deployment and retraction support for mining ropes. Background Technology

[0002] When removing hydraulic supports from the working face in coal mines, the limited roadway conditions prevent the direct use of large shovels for retraction. A traction winch is needed to deploy steel cables to pull the supports away. However, the steel cables used are quite thick and heavy, and the maximum drag distance is the length of the working face. Afterward, the cables must be manually pulled to the hydraulic supports. During this manual pulling process, the pulling speed must match the speed at which the winch lowers the cables, requiring multiple people working together. The entire process is time-consuming, labor-intensive, and carries high safety risks. Utility Model Content

The technical solution of this utility model is as follows: A mining rope winding and unwinding support includes a fixing assembly comprising a base, a first support, and a drum. The base is fixed to a hydraulic support, the first support is connected to the base, and both ends of the drum are resting on the first support. A mining rope is wound around the drum for connection to the wire rope of a traction winch. A braking assembly is also included, with one side connected to one end of the drum. A driver is provided, with its output shaft connected to the other side of the braking assembly. A connecting frame is provided, with one end connected to the base and the other end positioned horizontally perpendicular to the base.

[0004] Optionally, the brake assembly includes a brake disc; a sleeve inserted at the center of the brake disc, one end of the sleeve being connected to the output shaft of the driver, and the other end of the sleeve being connected to one end of the drum; a brake pad attached to one side of the brake disc; and a brake handle connected to the brake pad.

[0005] Optionally, the brake assembly further includes a plurality of fastening pins inserted into a sleeve. The plurality of fastening pins are respectively disposed on both sides of the brake disc. The output shaft of the driver and one end of the drum are both connected to the sleeve and fixed by the fastening pins.

[0006] Optionally, it also includes a cover that covers the outer periphery of the brake assembly and is attached to the fixing assembly.

[0007] Optionally, a connecting hole is provided on the connecting frame, and the end of the mining rope passes through the connecting hole and is connected to the end of the wire rope of the traction winch.

Detailed Implementation

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0017] like Figures 1 to 6 As shown, this utility model provides a mining rope winding and unwinding support, including a fixing component 1, which includes a base 11, a first support 12, and a drum 13. The base 11 is fixed on a hydraulic support, the first support 12 is connected to the base 11, and both ends of the drum 13 are attached to the first support 12. A mining rope is wound on the drum 13 for connection with the wire rope of a traction winch. A brake component 2 is provided, with one side connected to one end of the drum 13. A driver 3 is provided, with its output shaft connected to the other side of the brake component 2. A connecting frame 4 is provided, with one end connected to the base 11 and the other end of the connecting frame 4 positioned horizontally perpendicular to the base 11. The connecting frame 4 is located below the drum 13, and the mining rope is connected to the connecting frame 4.

[0018] Specifically, this application does not limit the type of the drive 3. Due to the complex environment in coal mines, the use of electrically driven drives 3 should be avoided as much as possible. Therefore, a pneumatic pump is used in this embodiment. The pneumatic pump is provided with an air source port 31, which is connected to an external air source to provide power to the pneumatic pump.

[0019] Furthermore, in this embodiment, the base 11 is fixed to the push rod of the hydraulic support by bolts, which not only avoids affecting the daily operation of the hydraulic support, but also facilitates the installation and disassembly of this application on the hydraulic support.

[0020] In a specific implementation, when it is necessary to retract the hydraulic support, the driver 3 is started, which drives the drum 13 to rotate and lower the mining rope wound on the drum 13. When one end of the mining rope is close to the wire rope lowered by the traction winch, the driver 3 is turned off. The workers connect the mining rope to the wire rope and start the driver 3 again, which drives the drum 13 to reverse, thereby recovering the mining rope and moving the hydraulic support toward the traction winch.

[0021] By setting up a fixed component 1, a brake component 2, a drive unit 3, and a connecting frame 4, the lowering and retrieval of the mining rope are realized. The mining rope and wire rope are connected, and the mining rope is retrieved, thereby driving the retraction of the hydraulic support. The wire rope of the traction winch is relatively thick and heavy, and manual dragging poses certain safety risks. This application uses a mechanized rope lowering and retrieval frame, which avoids manual dragging of the wire rope throughout the process, saving labor and wire rope lowering and retrieval time, and improving work efficiency. In case of emergency, the brake component 2 is activated to achieve emergency stop and avoid safety accidents. In addition, by setting the drum 13 on the first support 12, the drum 13 is erected at a higher position, which is more conducive to the lowering and retrieval of the mining rope.

[0022] Optionally, the brake assembly 2 includes a brake disc 21; a sleeve 22 inserted at the center of the brake disc 21, one end of the sleeve 22 being connected to the output shaft of the driver 3, and the other end of the sleeve 22 being connected to one end of the drum 13; a brake pad 23 attached to one side of the brake disc 21; and a brake handle 24 connected to the brake pad 23.

[0023] In a specific implementation, in an emergency, the operator can lift the brake handle 24 upwards to make the brake pads 23 fit tightly against the surface of the brake disc 21. During the rotation of the brake disc 21, the brake pads 23 rub against the surface of the brake disc 21 to achieve braking of the brake disc 21, thereby achieving emergency braking of the drum 13.

[0024] By setting up the brake assembly 2, in the event of a sudden event and the driver 3 is unable to stop quickly, the brake assembly 2 can be used to achieve emergency braking and avoid the occurrence of safety accidents. By setting up the sleeve 22, the driver 3 and the drum 13 can be quickly connected and disconnected from the brake assembly 2, and it is also convenient to replace the brake disc 21 or the brake pad 23.

[0025] Optionally, the brake assembly 2 also includes a plurality of fastening pins 25, which are inserted into the sleeve 22. The plurality of fastening pins 25 are respectively disposed on both sides of the brake disc 21. The output shaft of the driver 3 and one end of the drum 13 are both connected to the sleeve 22 and fixed by the fastening pins 25.

[0026] Specifically, in this embodiment, there are two fastening pins 25, which are respectively located on both sides of the brake disc 21.

[0027] In a specific implementation, after the output shaft of the driver 3 and one end of the drum 13 are both connected to the sleeve 22, one fastening pin 25 passes through the sleeve 22 and the driver output shaft 3 from top to bottom, and the other fastening pin 25 passes through the sleeve 22 and one end of the drum 13 from top to bottom, so as to achieve a stable connection between the output shaft of the driver 3 and the sleeve 22, as well as a stable connection between the drum 13 and the sleeve 22.

[0028] By setting the fastening pin 25, the output shaft of the driver 3, one end of the drum 13, and the sleeve 22 can be securely connected to each other, preventing them from coming loose.

[0029] Optionally, it also includes a cover 5, which covers the outer periphery of the brake assembly 2 and is connected to the fixing assembly 1.

[0030] By setting up the cover 5, the brake assembly 2 can be covered inside, thereby preventing dust and particulate matter in the environment from falling on the surface of the brake disc 21 and affecting the braking performance.

[0031] Optionally, a connection hole 41 is provided on the connecting frame 4, and the end of the mining rope passes through the connection hole 41 and is connected to the end of the wire rope of the traction winch.

[0032] By opening a connection hole 41 on the connecting frame 4, the mining rope is threaded through the connection hole 41, ensuring that the mining rope is lowered more smoothly without jamming, and also preventing the mining rope from swaying during the retrieval and release process.

[0033] Optionally, the fixing component 1 also includes a second bracket 14, which is connected to the base 11, and the driver 3 is mounted on the second bracket 14.

[0034] By setting a second bracket 14 to fix the driver 3, the overall structure of this application is more integrated and the floor space is reduced.

[0035] Optionally, the fixing component 1 also includes a third bracket 15, which is connected to the base 11. The cover 5 is mounted on the third bracket 15, and the brake component 2 is located between the cover 5 and the third bracket 15.

[0036] By setting a third bracket 15 to fix the cover 5, the cover 5 is stably covered on the outer periphery of the brake assembly 2.

[0037] Furthermore, this application also includes a fourth bracket, one end of the brake handle 24 is fixedly connected to one side of the fourth bracket, the fourth bracket is rotatably connected to the third bracket 15, and the brake pad 23 is connected to the other side of the fourth bracket; when no force is applied to the brake handle 24, there is a gap between the brake pad 23 and the surface of the brake disc 21, and the brake disc 21 rotates normally; when the other end of the brake handle 24 is lifted upward, the fourth bracket rotates on the third bracket 15, so that the brake pad 23 and the surface of the brake disc 21 are tightly fitted, thereby realizing the braking of the brake disc 21.

[0038] Optionally, the driver 3 is provided with a first switch 32 and a second switch 33. The first switch 32 is used to control the drum 13 to rotate counterclockwise, and the second switch 33 is used to control the drum 13 to rotate clockwise.

[0039] By setting the first switch 32 and the second switch 33, the driver 3 is rotated counterclockwise or clockwise by controlling different switches, thereby causing the drum 13 to rotate in different directions, thus realizing the lowering and retrieval of the mining rope.

[0040] It should be noted that in this embodiment, controlling the first switch 32 causes the driver 3 to rotate counterclockwise, and the mining rope is lowered; controlling the second switch 33 causes the driver 3 to rotate clockwise, and the mining rope is retrieved.

[0041] In summary, this application, by setting up a fixing component 1, a braking component 2, a driver 3, and a connecting frame 4, realizes the lowering and retrieval of mining ropes, connects mining ropes and wire ropes, and retrieves mining ropes, thereby driving the movement of hydraulic supports, which facilitates the retraction of hydraulic supports. The entire process avoids manual dragging of wire ropes, saving labor and time for wire rope deployment and retrieval, reducing the number of manual interventions required, and improving work efficiency. In case of emergency, the braking component 2 is activated to achieve emergency stopping and avoid safety accidents.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
