Description

Technical Field

[0001] The utility model relates to the technical field of endless rope winches, in particular to an endless rope speed-regulating mechanical winch for mining. Background Art

[0002] The infinitely variable rope speed mechanical winch is a winch that uses a variable frequency speed regulator to control the motor speed, has higher control accuracy and faster speed. It is a common rail continuous transportation equipment pulled by a wire rope in the underground coal mine tunnel. It is suitable for direct transportation of materials and equipment such as working face drifts, up (down) mountains in mining areas and concentrated rail tunnels under long-distance, large-angle, variable slope and large-tonnage working conditions. It is an ideal equipment to replace the traditional small winch relay and pulling transportation mode to realize the transportation of integral hydraulic supports and various equipment in mines. It can also be used for underground tunnels and ground in metal mines, and rail transportation with small slopes and undulating changes.

[0003] However, since the winch is installed on a working surface with a certain slope, in order to prevent the steel wire rope from being affected by the slope and generating friction with the winch base and the ground, most of the existing winch bases are provided with a rope support wheel for lifting the steel wire rope, and the rope support wheel lifts the steel wire rope to adjust its height. However, since the slope of the working surface flume varies, and the position of the rope support wheel on the existing winch base is fixed, when the winch is used on a working surface with a large slope, it is easy to encounter the problem that the rope support wheel is too low to lift the steel wire rope away from the slope, which will still cause friction between the steel wire rope and the slope, affecting the service life of the steel wire rope. Therefore, those skilled in the art provide a mining infinite rope speed regulating mechanical winch to solve the problems raised in the above background technology. Utility Model Content

The outer wall of the threaded rod 25 is located above the first ear 23 and the second ear 24 and is provided with a limit nut 251. The two limit nuts 251 are threadedly installed on the outer wall of the threaded rod 25 and are respectively tightly attached to the upper end surfaces of the first ear 23 and the second ear 24. In addition, the upper end surface of the end plate 21 is provided with two symmetrically distributed limit plates 26, and the lifting seat 3 is slidably installed between the two limit plates 26. In one embodiment, when using the infinitely variable rope speed regulating mechanical winch, the threaded rod 25 can be directly screwed on the first support ear 23 to drive the second support ear 24 installed thereon through the threaded groove 241 to move, and then the displaced second support ear 24 drives the end plate 21 installed thereon to move, so that the end plate 21 is displaced up and down above the limit seat 2 through the cooperation of the sliding rod 211 and the sleeve 22, and then the displaced end plate 21 drives the lifting seat 3 installed thereon and the two rope supporting wheels 33 installed on the lifting seat 3 to move, so as to adjust the height of the wire rope installed between the two rope supporting wheels 33, and the height of the wire rope can be adjusted according to the slope change of the working surface groove, so that the wire rope is kept away from the slope surface, avoiding the trouble of friction between the wire rope and the slope surface caused by the low height of the rope supporting wheel 33.

[0024] Combination Figure 1 , Figure 2 and Figure 3As shown, the inner sides of the two limit plates 26 are provided with sliding grooves 261, and the two ends of the lifting seat 3 are respectively slidably installed in the two sliding grooves 261. The upper end surface of the lifting seat 3 is located between the two limit plates 26 and is provided with two vertical plates 31 which are symmetrically distributed. Two guide shafts 32 which are distributed up and down are provided between the two vertical plates 31. The outer walls of the two guide shafts 32 are slidably installed with rope supporting wheels 33 for limiting the position of the wire rope, and a first buffer spring 27 is provided between the lifting seat 3 and the end plate 21. The rope supporting wheel 33 located at the top is tightly attached to the upper end surface of the rope supporting wheel 33 located at the bottom, and a second buffer spring 34 is provided between the side wall of the vertical plate 31 and the rope supporting wheel 33 and around the outside of the guide shaft 32. An arc groove 331 is provided at the middle position of the rope supporting wheel 33, and the two rope supporting wheels 33 are respectively engaged at the upper and lower ends of the wire rope through the two arc grooves 331, and the two arc grooves 331 are spliced ​​to form a limiting groove for limiting the position of the wire rope.

[0025] In one embodiment, when the wire rope is installed between the two rope support wheels 33 for use, the wire rope can be pulled from the rope outlet of the winch, the wire rope can be passed through the limiting groove between the two rope support wheels 33, and the wire rope can be fixed on the traction shuttle car for use. The two rope support wheels 33 can be respectively engaged with the upper and lower ends of the wire rope through the arc-shaped grooves 331 to limit it, which can prevent the wire rope from shaking and causing it to detach from the rope support wheels 33 and rub against the winch base 1 and the slope, thereby achieving the limitation of the wire rope.

[0026] The first buffer spring 27 is used to buffer the pressure on the rope support wheel 33, thereby reducing the friction between the wire rope and the rope support wheel 33, avoiding the damage of the wire rope or the rope support wheel 33 due to the large friction between the wire rope and the rope support wheel 33, and realizing the protection of the wire rope and the rope support wheel 33.

[0027] The working principle of the utility model is as follows: when the infinitely variable rope speed regulating mechanical winch is used on a working surface with a certain slope, the wire rope can be pulled from the rope outlet of the winch, the wire rope can be passed through the limiting groove between the two rope supporting wheels 33, and the wire rope can be fixed on the traction shuttle car for use, and then the threaded rod 25 is twisted to drive the second support ear 24 installed thereon through the threaded groove 241 to move, and then the displaced second support ear 24 drives the end plate 21 installed thereon to move, so that the end plate 21 is displaced up and down above the limiting seat 2 through the cooperation of the sliding rod 211 and the sleeve 22, and then the displaced end plate 21 drives the lifting seat 3 installed thereon and the two rope supporting wheels 33 installed on the lifting seat 3 to move, so as to adjust the height of the wire rope installed between the two rope supporting wheels 33, and the height of the wire rope can be adjusted according to the slope change of the working surface groove, so that the wire rope is kept away from the slope, avoiding the inability to lift the wire rope due to the low height of the rope supporting wheel 33. The wire rope is away from the slope surface, which causes the trouble of friction between the wire rope and the slope surface, thereby extending the service life of the wire rope. In addition, when the wire rope shakes, the wire rope can drive the rope support wheel 33 to slide left and right on the guide shaft 32, and the rope support wheel 33 squeezes the second buffer spring 34 wrapped around the guide shaft 32, and the second buffer spring 34 buffers the tension on the rope support wheel 33, and then the wire rope presses the rope support wheel 33 downward, and the rope support wheel 33 presses the second buffer spring 34 connected to it. When the vertical plate 31 moves downward, the vertical plate 31 pushes the lifting seat 3 to move downward in the slide groove 261 on the two limit plates 26 and squeezes the first buffer spring 27. The first buffer spring 27 buffers the pressure on the rope support wheel 33, reducing the friction between the wire rope and the rope support wheel 33, avoiding the situation where the wire rope or the rope support wheel 33 is damaged due to the large friction between the wire rope and the rope support wheel 33, thereby protecting the wire rope and the rope support wheel 33.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
