Abstract
Description
Technical Field
[0001] The utility model relates to coal mine personnel transportation, in particular to a coal mine auxiliary monkey car disembarking device. Background Art
[0002] The monkey cart, also known as a coal mine overhead passenger vehicle, is a widely used auxiliary transportation device in coal mines, primarily for transporting personnel. The use of the monkey cart significantly shortens miners' commuting time and conserves their energy. To use it, the miner lifts the cart, allowing the cart's grip to engage the traction wire rope. The cart is then driven by the traction wire rope, allowing the miner to board. However, disembarking requires concentration to maintain steady footing, as the transition from motion to rest is brief. Otherwise, they risk falling forward due to inertia, posing a safety hazard. Therefore, a device to assist disembarkation is required. Utility Model Content

[0015] Figure 3 This is a schematic diagram of the monkey car. DETAILED DESCRIPTION
[0016] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.
[0017] like Figure 1 and Figure 2 As shown, a device for assisting a monkey car to get off a coal mine includes a main steel pipe 1, an I-beam 11, a hanger and a lever 14;
[0018] The I-beam 11 is set as No. 11 mining I-beam, and the I-beam 11 is buried on the tunnel roof 20; the top ends of multiple groups of hangers are fixed on the I-beam 11, and each group of hangers includes a main hanger 21 and a secondary hanger 13; the hangers are fixed on the I-beam 11 by bolts 12.
[0019] The middle part of the main steel pipe 1 is hinged to the lower end of the main hanger 21 through the first pin shaft 22; the main steel pipe 1 can rotate around the first pin shaft 22, and the front and rear end rotation limit positions of the main steel pipe 1 are limited by the limit rod 5; the limit rod 5 is HRB500 steel bar, and the limit rod 5 is set in the tunnel side 19.
[0020] The middle position of the lever 14 is hinged to the lower end of the auxiliary hanger 13 through the second pin 4; the front and rear ends of the lever 14 are hinged to the first connecting rod 9 and the second connecting rod 23 respectively;
[0021] like Figure 2, also includes a pawl 3, the tail end of the pawl 3 is hinged on the main hanger 21, the middle is connected to the spring 7 fixed to the main hanger 21, and the head is hinged to the lower end of the first connecting rod 9; the main steel pipe 1 is provided with a corresponding slot, and the spring 7 provides a downward pulling force for the head of the pawl 3, so that the head of the pawl 3 is stuck in the slot to prevent the main steel pipe 1 from rotating. The first connecting rod 9 is pulled upward to make the head of the pawl 3 disengage from the slot;
[0022] There is an inclined surface below the rear end of the main steel pipe 1. When the rear end of the main steel pipe 1 is pressed down, the inclined surface fits with the steel wire rope 16 of the monkey car below.
[0023] A groove is provided on the upper surface of the rear half of the main steel pipe 1, and a movable member 2 is provided in the groove. The movable member 2 can move up and down in the groove and is restricted in the groove. The movable member 2 is hinged to the lower end of the second connecting rod 23;
[0024] The front end of the main steel pipe 1 is connected to a pull rope 10, which extends to a disembarkation point through a fixed pulley 8 on the tunnel roof 20. The other end of the pull rope 10 is connected to a lifting ring 15 at the disembarkation point. A counterweight 6 is provided at the front end of the main steel pipe 1.
[0025] When getting off the vehicle, pull the lifting ring 15, which drives the front end of the main steel pipe 1 to rise through the pull rope 10. The rear end of the main steel pipe 1 drops due to the connection with the first pin 22, and drops to the lowest position of the limit rod 5. The pawl 3 is pulled downward by the spring 7 and clamps the groove of the main steel pipe 1, and the position of the main steel pipe 1 is locked. The first connecting rod 9 drives the front end of the lever 14 to move downward due to the downward movement of the pawl 3, and the rear end of the lever 14 tilts upward, and drives the movable part 2 to move upward in the groove through the second connecting rod 23 until it is clamped by the groove limit of the main steel pipe 1.
[0026] like Figure 3 As shown, the rope gripper 18 of the monkey car is arranged corresponding to the wire rope 16, and the rope gripper 18 is arranged on the seat 17. The seat 17 and the rope gripper 18 are arranged along Figure 1 When the rope grip 18 reaches the rear end of the main steel pipe 1, the inclined surface of the rear end of the main steel pipe 1 contacts the steel wire rope 16, and the rope grip 18 separates from the steel wire rope 16. The rope grip 18 is guided to move onto the main steel pipe 1, and the rope grip 18 locks the main steel pipe 1.
[0027] The rope gripper 18 and the seat 17 continue to move forward on the main steel pipe 1 under the action of inertia. The rope gripper 18 and the seat 17 move forward to the groove of the main steel pipe 1, and rely on their own weight to press down the movable part 2 in the groove. The downward movement of the movable part 2 drives the rear end of the lever 14 to rotate downward, and the front end to tilt upward, and the first connecting rod 9 drives the pawl 3 to overcome the tension of the spring 7. The head of the pawl 3 rotates upward and disengages from the slot of the main steel pipe 1, so that the rotation of the main steel pipe 1 is unconstrained. The front end of the main steel pipe 1 is affected by the counterweight 6, and the front end rotates downward to the position of the limit rod 5 to complete the reset. The rope gripper 18 and the seat 17 are restricted in movement in the groove of the main steel pipe 1 and reach a stationary state, allowing the assistant to get on and off the monkey car in a stationary state.
[0028] It can be seen that the effective advantages of the utility model are: reasonable design, simple structure, cost saving, easy operation, and can be achieved without excessive modification of the original monkey car system underground.
[0029] The above description is only the best embodiment of the present invention, and not a limitation thereof. Therefore, modifications to the technical solutions described in the aforementioned embodiments or equivalent replacement of some of the technical features therein still fall within the scope of the technical solutions of the embodiments of the present invention.
