Description

Technical Field

[0001] This utility model relates to a wire rope anti-falling support roller for a monkey car, belonging to the technical field of auxiliary equipment for coal mine conveying. Background Technology

[0002] The full name of the "monkey car" is an aerial cableway for mining, primarily used for auxiliary transportation of workers in underground mines. Steel wire ropes are installed on drive wheels, support wheels, pressure wheels, and detour wheels, and tensioned by a tensioning device. Power is then output from the drive unit to move the drive wheels and steel wire ropes, thus transporting miners. The purpose of using aerial cableways in underground mines is to shorten the travel time for miners going up and down the mine, and to reduce the physical exertion required for their descent.

[0003] During the operation of the underground manned tram, the wire rope may fall off the rotating support roller due to various factors. Especially at the point of change of slope, if multiple wire ropes fall off the support roller in succession, it will pose a great danger to the passengers. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wire rope anti-falling support wheel for a monkey car, so as to solve the technical problems existing in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a wire rope anti-fall support roller for a monkey car, including a second support roller, the second support roller being coaxially fixed with a first support roller, a second rope groove being provided on the outer periphery of the second support roller, the diameter of the end of the second support roller near the first support roller being smaller than the diameter of the end of the first support roller near the second support roller, and the diameter of the end of the second support roller away from the first support roller being greater than or equal to the diameter of the end of the first support roller near the second support roller.

[0006] Preferably, the second support roller is provided with a countersunk threaded hole arranged coaxially with the first threaded hole of the first support roller, and the second support roller is mounted on the first support roller by a countersunk bolt.

[0007] Preferably, the second support roller is made of 45# steel.

[0008] Preferably, the second support roller has a semi-annular protrusion at one end near the first support roller that mates with the semi-annular groove of the first support roller.

[0009] Preferably, a blind hole is provided on the end of the second support roller away from the first support roller.

[0010] Preferably, the diameter of the end of the second support roller furthest from the first support roller is 150-160mm, and the length in the axial direction is 30-40mm.

[0011] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model can be well assembled with the original monkey car support wheel, can support the steel wire rope that falls from the original support wheel, and does not affect the passage of the monkey car seat. It has a novel design, simple structure, convenient installation, safe and reliable use, can save labor and costs, and improve the safety of people riding in the monkey car.

[0015] The reference numerals in the accompanying drawings include: second support roller 1, semi-annular protrusion 2, blind hole 3, second rope groove 4, countersunk threaded hole 5, first support roller 6, first threaded hole 7, first rope groove 8, and semi-annular groove 9. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1:

[0018] Existing wire rope support roller structure for monkey buses, such as Figure 1 As shown: It includes a first support roller 6, which is rotatably connected to the frame. The outer periphery of the first support roller 6 is provided with a first rope groove 8, and the two ends of the first rope groove 8 are symmetrical. Two first threaded holes 7 are symmetrically provided on the first support roller 6, and a semi-annular groove 9 is provided on the right end of the first support roller 6.

[0019] A type of monkey bus with a steel wire rope anti-fall roller, such as Figures 2-3 As shown, the device includes a second support roller 1. The second support roller 1 has two countersunk threaded holes 5 coaxially arranged with the first threaded hole 7 of the first support roller 6. The second support roller 1 is mounted on the first support roller 6 using countersunk bolts, achieving coaxial fixation between the second support roller 1 and the first support roller 6, thus enabling the second support roller 1 to be rotatably connected to the frame. A second rope groove 4 is provided on the outer circumference of the second support roller 1. The diameter of the left end of the second support roller 1 is smaller than the diameter of the right end of the first support roller 6, and the diameter of the right end of the second support roller 1 is greater than or equal to the diameter of the right end of the first support roller 6. In this embodiment, the diameter of the right end of the second support roller 1 is 160mm, and its axial length is 40mm. The second support roller 1 is machined from 45# steel.

[0020] In this embodiment, a semi-annular protrusion 2 is provided on the end of the second support roller 1 near the first support roller 6, which mates with the semi-annular groove 9 of the first support roller 6. This facilitates the synchronous rotation of the first support roller 6 and the second support roller 1.

[0021] In this embodiment, a blind hole 3 is provided on the end of the second support roller 1 that is away from the first support roller 6. This saves materials and reduces costs.

[0022] Using the first threaded hole 7 on the first support roller 6, the second support roller 1 is installed on the first support roller 6. The second support roller 1 can support the wire rope that falls from the first support roller 6, effectively preventing the wire rope from falling and not affecting the passage of the monkey car seat. This utility model is very convenient to assemble and disassemble.

[0023] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
