Description

Technical Field

[0001] The utility model relates to the technical field of man - riding hoist, and more specifically to a headstock of a man - riding hoist for mine use. Background Technique

[0002] The man - riding hoist is called an overhead passenger device. As a transportation equipment, it is mainly used in underground mines. Its conveying principle and function are as follows: First, the steel wire rope is installed on the driving wheel, supporting rope wheel, pressing rope wheel, double - towing wheel or double - pressing wheel, bypass wheel and tightened by a tensioning device. Then, the driving device outputs power to drive the driving wheel and the steel wire rope to run, thus realizing the principle of conveying miners. Using the man - riding hoist to convey miners aims to shorten the journey time of miners going up and down the well and reduce the physical energy consumption of miners going up and down the well. Thus, it can be seen that the man - riding hoist is one of the important personnel - transporting equipment required in coal mine sites, effectively solving the problem of long - distance and large - vertical - degree personnel transportation in underground mines and realizing long - time continuous transportation.

[0003] The man - riding hoist is driven by an electric motor installed at the headstock to drive the friction wheel on the speed reducer as the driving device, and uses an overhead endless steel wire rope as the traction and load - bearing. Thus, it can be seen that the headstock of the man - riding hoist is the key equipment for controlling the operation of the man - riding hoist. The existing structure of the headstock of the man - riding hoist is as Figure 1 shown.

[0004] With the existing installation structure, since the driving wheel adopts a single - groove structure, for the steel wire rope installed on the driving wheel, due to the small contact area between the steel wire rope and the driving wheel, the corresponding friction force is reduced, which easily causes the steel wire rope to slip. At the same time, due to the small wrap angle between the steel wire rope and the driving wheel, the contact arc length between the steel wire rope and the surface of the driving wheel becomes shorter. In this way, the total friction force generated between the contact surfaces is also smaller, and thus the steel wire rope will also slip due to the reduction of the friction force. In addition, during the operation of the steel wire rope, the steel wire rope may deviate due to other factors and needs to be adjusted in time. The existing adjustment method can only adjust the driving wheel, and adjust the steel wire rope by adjusting the driving wheel. With the existing adjustment method, it is necessary to stop the machine before adjustment. During the adjustment process, it is necessary to repeatedly rotate the driving wheel, which is not only troublesome to operate, increases the workload of the operator, but also affects the operation efficiency of the man - riding hoist. Therefore, in order to eliminate potential safety hazards, the structure of the existing headstock of the man - riding hoist needs to be improved to avoid affecting the normal operation of the man - riding hoist due to the slipping of the steel wire rope. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a headstock of a man - riding hoist with simple structure and convenient operation aiming at the problems in the background technique. By using this headstock of the man - riding hoist, it can effectively avoid affecting the normal operation of the man - riding hoist due to the slipping of the steel wire rope, thus eliminating potential safety hazards and ensuring its safe operation. More specifically, it is a headstock of a man - riding hoist for mine use.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a monkey car head for mines, including a frame, a head motor and a reducer installed on the frame, and a driving wheel installed in the frame, the head motor and the reducer are both installed on the top of the frame, the output shaft of the head motor is connected to the input end of the reducer, the output end of the reducer is connected to a connecting shaft that vertically passes through the frame downward, and the driving wheel is installed at the bottom of the frame, and the driving wheel is fixedly connected to the connecting shaft; a guide wheel is also installed at the bottom of the frame, the guide wheel is located directly below the head motor, and the driving wheel and the guide wheel are connected by a wire rope transmission.

[0007] Furthermore, the monkey car head for use in mines described in the utility model is also provided with a support frame at the bottom of the frame, and the support frame and the frame are fixed to form an integrated structure by welding. A bearing seat is provided in the support frame, and the bearing seat is equipped with a bearing and a bearing end cover matching the bearing. The bearing is installed on the bearing seat through the bearing end cover; the lower end of the connecting shaft passes through the bearing end cover and is matched with the bearing in the bearing seat; the driving wheel is fixed in the connecting shaft in a horizontal state.

Example 1

[0021] like Figure 2 and Figure 3 As shown, the head of a monkey car for mines described in this embodiment includes a frame 1, a head motor 2 and a reducer 3 installed on the frame 1, and a driving wheel 4 installed in the frame 1, wherein the head motor 2 and the reducer 3 are both installed on the top of the frame 1, and the output shaft of the head motor 2 is connected to the input end of the reducer 3, and the output end of the reducer 3 is connected to a connecting shaft 5 that vertically passes through the frame 1 downward, and the driving wheel 4 is installed at the bottom of the frame 1, and the driving wheel 4 is fixedly connected to the connecting shaft 5; a guide wheel 6 is also installed at the bottom of the frame 1, and the guide wheel 6 is located directly below the head motor 2, and the driving wheel 4 and the guide wheel 6 are connected by a steel wire rope (not shown in the figure). Among them, the driving wheel 4 is set to a double-slot structure, and the guide wheel 6 is set to a single-slot structure.

[0022] Further, by adopting a mine man-riding cableway headstock described in this embodiment, in order to facilitate the installation of a driving wheel 4 and a guiding wheel 6, a support frame 7 is further provided at the bottom of the frame 1. The support frame 7 and the frame 1 are fixed into an integral structure by welding. A bearing seat 8 is provided in the support frame 7. A bearing 9 is provided in cooperation with the bearing seat 8, and a bearing end cover 10 matching the bearing 9 is configured. The bearing 9 is installed on the bearing seat 8 through the bearing end cover 10. The lower end of the connecting shaft 5 passes through the bearing end cover 10 and is in fit connection with the bearing 9 in the bearing seat 8. The driving wheel 4 is horizontally fixed in the connecting shaft 5. At the same time, a support shaft 11 is provided in the support frame 7. The top of the support shaft 11 is connected to the frame 1. The guiding wheel 6 is configured with a bushing matching the support shaft 11. The guiding wheel 6 is installed in the support shaft 11 through the bushing and can rotate synchronously with the driving wheel 4 around the support shaft 11. Embodiment 2

[0023] Based on Embodiment 1, in this embodiment, in order to improve the load-bearing capacity of the steel wire rope, the wrap angle between the steel wire rope and the driving wheel 4 cannot be too small. It is required that the diameter of the guiding wheel 6 is not greater than that of the driving wheel 4. In this way, the wrap angle can be changed by the provided guiding wheel 6, and the friction between the driving wheel 4 and the steel wire rope can be increased. The steel wire rope is driven by the friction between the driving wheel 4 and the steel wire rope, and then the personnel are transported by the seats installed in the steel wire rope. The condition for the steel wire rope not to slip is that the component force of the steel wire rope along the reverse direction of the movement of the steel wire rope is not greater than the friction between the driving wheel 4 and the steel wire rope.

[0024] By adopting a mine man-riding cableway headstock described in the present utility model, the driving wheel 4 is arranged in a double-groove structure by installing the guiding wheel 6 in the frame 1. Through the cooperation of the guiding wheel 6 and the driving wheel 4, the steel wire rope is first installed in one groove of the driving wheel 4, then passes through the single groove of the guiding wheel 6, and then returns to the other groove of the driving wheel 4, and finally the steel wire rope is arranged according to the existing method. Since the steel wire rope contacts the driving wheel 4 through the double grooves, the contact area between the steel wire rope and the driving wheel 4 is increased, and the wrap angle between the steel wire rope and the driving wheel 4 can also be increased. In this way, the friction between the steel wire rope and the driving wheel 4 can be increased, and the phenomenon of the steel wire rope slipping can be effectively avoided. At the same time, the guiding wheel 6 can be used to adjust the deviated steel wire rope. Without adjusting the driving wheel 4, the steel wire rope can be adjusted, which greatly reduces the workload of the operator and does not affect the normal operation of the man-riding cableway.

[0025] In summary, by adopting the man-riding cableway headstock described in the present utility model, through the improvement of the existing structure, not only can the phenomenon of the steel wire rope slipping be prevented, but also the deviated steel wire rope can be conveniently adjusted, effectively avoiding the influence on the normal operation of the man-riding cableway due to the slipping of the steel wire rope, thereby eliminating potential safety hazards and ensuring its safe operation. Its overall structure is simple and is conducive to popularization and use.
