Description

Technical Field

[0001] This utility model relates to the field of mining winch technology, specifically a mining emulsion-powered bidirectional winch. Background Technology

[0002] The equipment withdrawal operation in a fully mechanized longwall mining face is an important part of ensuring the continuity of coal mine production. In order to achieve safe and rapid withdrawal, various electromechanical equipment needs to be used in conjunction to complete the withdrawal operation.

[0003] When retracting the scraper conveyor equipment at the rear of the fully mechanized longwall face, a JSDB-30 dual-speed multi-purpose winch (50T winch) is required to retract the scraper chain, rear chute, and other equipment. Calculations show that φ38mm steel wire rope is needed for hauling. The weight of each meter of steel wire rope is 5.49kg / m, and the maximum hauling distance is 300m. The total weight of 300m of steel wire rope is 1647kg, which is quite heavy. It needs to be manually dragged above the rear scraper conveyor. Typically, the walking height is less than 1.5m, resulting in insufficient working space, a large hauling weight, and safety risks such as excessive gas levels, roof collapse, and coal slurry accumulation in the limited area behind the support. Prolonged high-intensity work poses a risk of safety accidents. Utility Model Content

[0011] Preferably, the outer surface of the outer cover is provided with a groove, and the outer surface of the groove is slidably connected to the outer surface of the rope pressing seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application utilizes the coordination between the motor, dual-directional mechanism, and drum to retract the rear scraper conveyor equipment from the tail side using a 50T winch. The emulsion-powered winch is securely positioned at the headstock frame, and the wire rope is fixed and wound at least three turns. Then, the spare operating valve of the tailstock frame is connected to the corresponding inlet and outlet of the hydraulic valve group of the emulsion-powered winch. The wire rope of the emulsion-powered winch is laid from the headstock to the tailstock and connected to the 50T winch wire rope. While the 50T winch rapidly releases the rope, the emulsion-powered winch is operated to drag the wire rope. When moving the equipment to its location, the emulsion-powered winch wire rope is simultaneously pulled to the tail side of the machine. The dual-directional mechanism ensures that the drum device rotates in reverse without jamming. When the emulsion-powered motor is reversed, the circuit routing of the dual-directional mechanism is changed simultaneously, thereby ensuring that the drum with the wire rope wound on it can rotate in reverse. This reduces the number of rope unloading steps, making it convenient and quick, and eliminating the risk of rope breakage or equipment damage due to asynchrony. It also greatly reduces the time that personnel spend working in the limited area behind the support, reducing the risk of poisoning, suffocation, and injury from the roof, and improving the safety factor of the operation.

[0014] 2. This application utilizes the cooperation between the outer cover, pressure plate frame, slide groove, rope pressing rod, and rope pressing seat. The outer cover provides protection for the internal drum and the wire rope wound on the drum surface. The slide rod is fitted with a conventional spring. Therefore, the pressure plate frame and rope pressing rod, through gravity and the thrust of the spring, firmly press the rope pressing rod against the wire rope wound on the drum surface. When the wire rope is retracted or released, it passes through the inner wall of the rope pressing seat, thereby causing the rope pressing seat to rotate left and right on the slide groove. Through the cooperation with the rope pressing rod, the purpose of fixing the wire rope and preventing the wire rope from bouncing is achieved. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-5As shown, this utility model provides a technical solution for a mining emulsion-powered bidirectional winch, including an emulsion-powered motor 1, a load-bearing plate 2 below the motor 1, a double-directional mechanism 3 above the load-bearing plate 2, a drum 4 on one side of the double-directional mechanism 3, a rope-pressing rod 5 above the drum 4, and a rope-pressing seat 6 on one side of the drum 4. When using a 50T winch to retract the rear scraper conveyor equipment from the tail side, the emulsion-powered winch is stably fixed at the head frame position, the wire rope is fixed and wound at least three turns, and then the spare operating valve of the tail frame is connected to the inlet and outlet of the hydraulic valve group 7 of the emulsion-powered winch, and the wire rope of the emulsion-powered winch is laid from the head to the... The tail section is connected to a 50T winch wire rope. While the 50T winch quickly releases the rope, the emulsion-powered winch is operated to drag the wire rope to the retraction equipment position. When transporting the equipment, the wire rope of the emulsion-powered winch is simultaneously moved to the tail side. The dual-directional mechanism 3 ensures that the drum 4 device rotates in reverse without jamming. When the emulsion-powered motor 1 is reversed, the circuit routing of the dual-directional mechanism 3 is changed at the same time, thereby ensuring that the drum 4 with the wire rope wound can rotate in reverse, thus reducing the rope release steps, making it convenient and quick, and eliminating the risk of rope breakage or equipment damage due to asynchronous operation. It greatly reduces the time that personnel work in the limited area at the rear of the support, reduces the risk of poisoning and suffocation, and injury from the roof, and improves the safety factor of the operation.

[0023] A hydraulic valve group 7 is fixedly installed on the outer surface of the motor 1, and a load-bearing frame 8 is fixedly installed on the outer surface of the motor 1. The outer surface of the load-bearing frame 8 is fixedly installed on the outer surface of the load-bearing plate 2. The hydraulic valve group 7 adopts the hydraulic valve group 7 system that is common to the working face support, and can realize the connection from the spare hydraulic valve group 7 of the support to provide a power source for the motor 1.

[0024] The output end of the motor 1 is fixedly mounted with an output shaft 9. The dual-directional mechanism 3 includes a connecting sleeve 301. The outer surface of the connecting sleeve 301 is fixedly mounted with the outer surface of the output shaft 9. A ratchet 302 is fixedly mounted on the outer surface of the connecting sleeve 301. When the motor 1 is running, it can drive the ratchet 302 to rotate through the connecting sleeve 301.

[0025] A connecting frame 303 is provided below the ratchet 302. The outer surface of the connecting frame 303 is fixedly installed on the outer surface of the load-bearing plate 2. A slide rail 304 is fixedly installed on the outer surface of the connecting frame 303. A pulley 305 is slidably connected to the outer surface of the slide rail 304. A movable plate 306 is rotatably connected to the outer surface of the pulley 305. A metal column 307 is fixedly installed on the outer surface of the movable plate 306. An electromagnet 308 is fixedly installed on the outer surface of the connecting frame 303 and the metal column 307. The connecting frame 303 can provide support for the movable plate 306 through the slide rail 304 and the pulley 305. When the motor 1 changes direction, the circuit to the electromagnet 308 is changed simultaneously through the central control device. When one of the electromagnets 308 is energized, the electromagnet 308 will quickly pull the metal column 307 and the movable plate 306 toward the electromagnet 308 and attach to it. The other electromagnet 308 will lose its magnetic force due to the power failure.

[0026] A guide rod 309 is fixedly installed on the outer surface of the movable plate 306. A limiting pawl 310 is rotatably connected to the outer surface of the guide rod 309. A torsion spring is sleeved on the outer surface of the guide rod 309. There are two limiting pawls 310. The outer surface of one of the limiting pawls 310 is in contact with the outer surface of the ratchet 302. A drive shaft 10 is fixedly installed on the outer surface of the ratchet 302. One end of the drive shaft 10 is fixedly installed on the outer surface of the drum 4. The torsion spring can continuously drive the limiting pawl 310 to reset. The limiting directions of the two limiting pawls 310 are opposite to each other. Therefore, when the left limiting pawl 310 contacts the ratchet 302, the ratchet 302 can only rotate clockwise, and vice versa.

[0027] An outer cover 11 is fixedly installed on the outer surface of the load-bearing plate 2. The inner side wall of the outer cover 11 is rotatably connected to the outer surfaces of both ends of the drum 4. A connecting plate 12 is fixedly installed on the outer surface of the outer cover 11. A sliding column 13 is fixedly installed on the outer surface of the connecting plate 12. A pressure plate frame 14 is slidably connected to the outer surface of the sliding column 13. The inner wall of the pressure plate frame 14 is rotatably connected to the outer surface of the pressure rope rod 5. The outer cover 11 can provide protection for the drum 4 inside and the wire rope wound on the surface of the drum 4. A conventional spring is sleeved on the surface of the sliding column 13. Therefore, the pressure plate frame 14 and the pressure rope rod 5 will press the pressure rope rod 5 firmly against the wire rope wound on the surface of the drum 4 through gravity and the thrust of the spring.

[0028] The outer surface of the outer cover 11 is provided with a groove 15. The outer surface of the groove 15 is slidably connected to the outer surface of the rope pressing seat 6. When the wire rope is retracted or released, it will pass through the inner wall of the rope pressing seat 6, thereby driving the rope pressing seat 6 to rotate left and right on the groove 15. Through the cooperation with the rope pressing rod 5, the purpose of fixing the wire rope and preventing the wire rope from bouncing is achieved.
