Description

Technical Field

[0001] This utility model belongs to the technical field of mining transportation equipment, specifically relating to an in-tank vehicle blocking device driven by an electric motor. Background Technology

[0002] Currently, with the development of mine hoisting technology, the automation level of mining equipment is receiving increasing attention. Most of the car stoppers used in mine cages are manually operated. During the hoisting and unloading operations at the mine entrance, the opening or closing of the car stopper requires manual operation, which is time-consuming, labor-intensive, and inefficient. This cannot adequately meet the mine hoisting efficiency requirements. In addition, manual car stoppers have a rough structure, a high failure rate, and high operational safety risks. The low hoisting efficiency at the mine entrance also affects the safe operation of the mine cars inside the cage during the hoisting and unloading process, posing certain safety risks. Utility Model Content

[0003] This invention provides a tank-mounted vehicle blocking device driven by an electric motor, which aims to solve the problem that existing vehicle blocking devices require manual opening or closing, resulting in low efficiency.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] This utility model relates to an electric vehicle stop device, which uses a transmission shaft to drive a pawl that swings left and right. The device primarily consists of a motor, a reducer, a coupling, a copper sleeve, a shaft seat, an upper cover for the shaft seat, a transmission shaft, pawls, a buffer spring, fixing screws, a fixed base plate, and an electrical control system. The fixed base plate is fixed inside the cage on the outside of the railway track. The reducer and shaft seat are bolted to the fixed base plate. The transmission shaft, pawls, buffer spring, and coupling are fixed via the shaft seat. The motor's rotation drives the pawls to swing left and right, thus blocking and allowing mine car wheels to pass. The motor is connected to an electrical control box, powered by a rechargeable battery, and its start and stop are controlled by a remote control.

[0006] The beneficial effects of this utility model are as follows: The motor-driven wheel stop device disclosed in this utility model is flexible in operation and convenient in maintenance, which greatly reduces the labor intensity of workers, saves maintenance time, improves the efficiency of cage lifting and unloading, and achieves high efficiency, safety and reliability.

Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0011] like Figure 1 and 2 As shown, a tank-mounted vehicle blocking device driven by an electric motor mainly includes a motor 5, a reducer 6, a coupling 7, a front shaft seat upper end cover 8, a front shaft seat 9, a copper sleeve 10, a blocking claw 11, a transmission shaft 12, a buffer spring 13, a limit nut 14, a rear shaft seat 15, a rear shaft seat upper end cover 16, and a fixed base plate 4.

[0012] First, install and fix the base plate 4 according to the positions of the cage bottom plate 1 and the railway 2 inside the cage. Install the front axle seat 9, motor 5, and reducer 6 on the fixed base plate. The pawl 11 is threaded onto the drive shaft 12 and fixed with a key. The front and rear shaft ends of the drive shaft 12 are fixed to the front axle seat 9 and the rear axle seat 15. Copper sleeves 10 are fitted on the shaft ends. The shaft is fixed on the axle seats by the upper end cover 8 of the front axle seat and the upper end cover 16 of the rear axle seat. The reducer 6 is connected to the drive shaft 11 through an internal gear coupling 7. A buffer spring 13 is installed on the drive shaft. There is an adjustable limit nut 14 at the rear of the spring to adjust the tension of the spring. The motor 5 is connected to the electrical control box and is powered by a rechargeable battery. The battery is fixedly installed in the cage. The start and stop of the motor are controlled by a remote control, which in turn controls the opening or closing of the pawl.

[0013] The specific working principle of this example is as follows: The operator controls the forward and reverse rotation of motor 5 via the remote control's car stop button. The rotation of motor 5 then drives the opening and closing of the stop claw 11. Before the mine car enters the cage, the stop claw 11 swings towards the side of the cage, the car stop opens, and the mine car wheel enters the cage along the internal railway. After the mine car enters the cage and enters the slot, the car stop is operated again, and the stop claw 11 swings towards the side of the cage railway, the stop claw engages with the cage railway, the car stop closes, and the mine car wheel is limited, preventing the mine car from moving forward.
