Description

Technical Field

[0001] This utility model relates to the field of trolley head technology, specifically to a gravity-powered electric trolley head. Background Technology

[0002] Hydraulic motor-driven car pushers are widely used in coal and metal mine yards, primarily responsible for the scheduling and transportation of mine cars. The pusher head, as the direct connector between the mine car and the pusher, plays a particularly important role.

[0003] In existing technology, the horizontal or raised state of the pusher claw on the trolley head is controlled by a top block driven by a hydraulic cylinder or other components fixed in a ground position. Whether the pusher claw pushes the car and the direction of pushing are adjusted to suit the on-site operating environment, thereby controlling whether the mine car is pushed and the direction of pushing. This working method requires the trolley head to be in a fixed position to change its working state, increasing operational complexity. Due to the rapidly changing conditions in the mine yard, fixed control components cannot adapt to these changes, or require even more control components to barely meet the requirements. A gravity-powered electric trolley head is needed to solve the aforementioned problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gravity-powered electric trolley head to solve the problems mentioned in the background technology. This utility model has a reasonable structure, the push claw is easy to operate in horizontal or tilted state, and the position of the push claw in horizontal or tilted state can be randomly controlled, which can adapt to the ever-changing parking lot scheduling conditions.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gravity-powered electric trolley head, comprising:

[0006] The vehicle body is equipped with casters, and a pusher is rotatably mounted inside the vehicle body.

[0007] The vehicle body is equipped with a limiting partition for limiting the pusher to maintain a horizontal state. A guide seat is provided through the limiting partition. A return spring is provided inside the guide seat. A drive rod is sleeved inside the return spring and passes through the guide seat. An electric push rod is provided inside the vehicle body for pushing the drive rod to press the return spring and push the pusher to rotate from a raised state to a horizontal state.

[0011] Furthermore, the limiting partition includes an inclined plate disposed inside the vehicle body and inclined downward, a horizontal plate disposed at the bottom of the inclined plate, and a vertical plate disposed on the side wall of the horizontal plate;

[0012] When the pusher is in a horizontal state, the lower end face of the pusher head is flush with the upper end face of the horizontal plate;

[0013] When the pusher is in the raised state, the lower end face of the pusher counterweight is flush with the lower side of the inner wall of the vehicle body.

[0014] Furthermore, a mounting groove is formed between the side of the limiting partition near the electric push rod and the inner wall of the vehicle body, and the electric push rod, the battery and the wireless receiver controller are all located inside the mounting groove;

[0015] The side of the limiting partition away from the electric push rod forms a rotating groove between itself and the inner wall of the vehicle body, and the push claw is located inside the rotating groove.

[0016] Furthermore, the top of the vehicle body is provided with a cover plate for sealing the mounting groove.

[0017] Furthermore, the side wall of the vertical plate is provided with a through groove, and the guide seat is located inside the through groove;

[0018] A limiting hole is provided on the side of the guide seat near the electric push rod, and a guide hole communicating with the limiting hole is provided on the side of the guide seat away from the electric push rod.

[0019] The drive rod includes a pressure plate disposed inside the limiting hole and used to press the return spring. The end of the pressure plate is provided with a force-applying column that is inserted into the return spring and matches the guide hole, and the force-applying column passes through the guide hole.

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] like Figure 1 As shown, this utility model provides a technical solution: a gravity-powered electric trolley head, comprising:

[0035] The vehicle body 1 is equipped with movable wheels 2, and a pusher 10 is rotatably mounted inside the vehicle body 1.

[0036] The vehicle body 1 is equipped with a limiting partition 9 for limiting the pusher 10 to maintain a horizontal state. A guide seat 13 is provided through the limiting partition 9. A return spring 14 is provided inside the guide seat 13. A drive rod 12 that passes through the guide seat 13 is sleeved inside the return spring 14. An electric push rod 8 is provided inside the vehicle body 1 for pushing the drive rod 12 to press the return spring 14 and push the pusher 10 to rotate from the raised state to the horizontal state. This design uses an electric push rod 8 to drive a drive rod 12, which in turn rotates the pusher 10 from a raised position to a horizontal position. This avoids interference between the pusher 10 and the axle of the mine car, allowing the car body 1 to move the pusher 10 to the appropriate pushing position of the mine car. When the mine car needs to be pushed, the electric push rod 8 drives the drive rod 12 to stop pushing the pusher 10. At this time, the return spring 14 rebounds, and the pusher 10 returns to the raised position, facilitating connection with the axle of the mine car and pushing the mine car. The pusher 10 can be easily adjusted to be in a horizontal or raised position, and the adjustment of the horizontal or raised position is random, providing high flexibility and adaptability to rapidly changing yard scheduling conditions. The telescopic shaft of the electric push rod 8 is in contact with the end face of the drive rod 12.

[0037] Reference Figure 1 and Figure 7The vehicle body 1 is equipped with an antenna 4, and a wireless receiver controller 6 is installed inside the vehicle body 1. The antenna 4 is connected to an external remote control, the wireless receiver controller 6 is connected to the wireless receiver controller 6, and the wireless receiver controller 6 is connected to an electric push rod 8. A battery 5 is installed inside the vehicle body 1 to power the wireless receiver controller 6, the antenna 4, and the electric push rod 8. In this design, pressing a button on the remote control sends a signal to the antenna 4 via its internal wireless transmitter controller and built-in antenna. The antenna 4 receives the signal and transmits it to the wireless receiver controller 6. The wireless receiver controller 6 controls the electric push rod 8 to execute corresponding action signals, facilitating remote control of the electric push rod 8 to adjust the push claw 10 to a horizontal or tilted state; the action signal is the extension or retraction signal of the electric push rod 8. The antenna 4 is embedded in the top of the vehicle body 1.

[0038] Reference Figure 1 The pusher 10 includes a pusher head 101 and a pusher counterweight 102. The pusher head 101 is located on top of the pusher counterweight 102, and the pusher counterweight 102 is located inside the vehicle body 1.

[0039] A connecting pin 11 is provided between the pusher counterweight 102 and the vehicle body 1. This design ensures that the pusher head 101 remains in a raised state when the drive rod 12 does not apply force to the pusher 10, and the connecting pin 11 facilitates the rotation of the pusher 10.

[0040] Reference Figure 1 and Figure 3 The limiting partition 9 includes an inclined plate 91 that is installed inside the vehicle body 1 and tilts downwards. A horizontal plate 92 is provided at the bottom of the inclined plate 91, and a vertical plate 93 is provided on the side wall of the horizontal plate 92.

[0041] When the pusher 10 is in a horizontal position, the lower end face of the pusher head 101 is flush with the upper end face of the horizontal plate 92.

[0042] When the pusher 10 is in the raised state, the lower end face of the pusher counterweight 102 is flush with the lower side of the inner wall of the vehicle body 1. This design uses the horizontal plate 92 on the limiting partition 9 to facilitate the limiting of the pusher head 101, ensuring that the top of the pusher head 101 is in a horizontal state. The pusher counterweight 102 has an arc-shaped protrusion on the side near the drive rod 12, and the position of the drive rod 12 corresponds to the position of the arc-shaped protrusion, which facilitates the application of force to the pusher counterweight 102 to drive the pusher head 101 to a horizontal state.

[0043] Reference Figure 3 The side of the limiting partition 9 near the electric push rod 8 forms a mounting groove 1001 with the inner wall of the vehicle body 1. The electric push rod 8, the battery 5 and the wireless receiver controller 6 are all located inside the mounting groove 1001.

[0044] A rotating groove 1002 is formed between the side of the limiting partition 9 away from the electric push rod 8 and the inner wall of the vehicle body 1, and the push claw 10 is located inside the rotating groove 1002. This design facilitates the installation of the electric push rod 8, the battery 5, and the wireless receiver controller 6 through the mounting groove 1001; wherein, an explosion-proof connector is provided on the side of the vehicle body 1 near the antenna 4, and the explosion-proof connector is connected to the inner wall of the vehicle body 1 to facilitate the transmission of wires and connection to the electric push rod 8, the battery 5, and the wireless receiver controller 6.

[0045] Reference Figure 3 and Figure 4 The top of the vehicle body 1 is provided with a cover plate 7 for sealing the mounting groove 1001. This improves the rationality of the design.

[0046] Reference Figure 1 and Figure 2 The vertical plate 93 has a through groove 931 on its side wall, and the guide seat 13 is located inside the through groove 931;

[0047] A limiting hole 132 is provided on the side of the guide seat 13 near the electric push rod 8, and a guide hole 131 connected to the limiting hole 132 is provided on the side of the guide seat 13 away from the electric push rod 8.

[0048] The drive rod 12 includes a pressure plate 122 disposed inside the limiting hole 132 and used to press the return spring 14. The end of the pressure plate 122 is provided with a force-applying column 121 that inserts into the return spring 14 and matches the guide hole 131, with the force-applying column 121 penetrating through the guide hole 131. This design facilitates the movement of the force-applying column 121 along the guide hole 131 and the movement of the limiting plate along the limiting hole 132, improving the stability of the drive rod 12's movement. The diameter of the pressure plate 122 is larger than the diameter of the force-applying column 121, facilitating the pressing operation of the return spring 14, which is located inside the limiting hole 132. The pressure plate 122 is always located inside the limiting hole 132.

[0049] Reference Figure 1 , Figure 4 and Figure 5 On each of the opposite side walls of the vehicle body 1, there is a pair of connecting lugs 3. A connecting groove 31 is formed between the pair of connecting lugs 3 to connect with the frame of the mobile trolley 15. A mounting pin 32 is provided through the top of the pair of connecting lugs 3. This design facilitates the connection between the vehicle body 1 and the mobile trolley 15 through the connecting lugs 3, the limiting groove, and the mounting pin 32. Under the action of the mounting pin 32, the vehicle body 1 can turn around the mounting pin 32 and follow the mobile trolley 15.

[0050] Reference Figure 1 , Figure 5 and Figure 6The gravity-powered electric trolley heads are arranged in pairs symmetrically and connected to the end of the moving trolley 15. This design, through the symmetrical arrangement of the gravity-powered electric trolley heads, ensures that the push claws 10 on the paired gravity-powered electric trolley heads can perform bidirectional adjustment and conveying of the mine car.

[0051] Reference Figures 1-7 As one embodiment of this utility model: wherein, Figure 1 and Figure 3 The black dots at the joints of the components are weld points. The joint length of the guide hole 131 and the joint gap between the guide hole 131 and the force-applying column 121 meet the requirements of GB3836.2-2010 Explosive Atmospheres Part 2: Equipment protected by explosion-proof enclosures "d". When it is necessary to push the mine car, it is connected to the mobile trolley 15 through the car body 1. The mobile trolley 15 is composed of multiple parts and is equipped with multiple connecting columns. The distance between the multiple connecting columns matches the teeth of the gears. The mobile trolley 15 can be driven by the hydraulic motor and gears to move the car body 1.

[0052] The electric push rod 8 drives the drive rod 12 to apply force to the push claw counterweight 102 on the push claw 10. The push claw counterweight 102 rotates, causing the push claw head 101 to rotate from the raised state to the horizontal state, avoiding interference between the push claw 10 and the wheel axle of the mine car. When the car body 1 moves the push claw 10 to the appropriate pushing position of the mine car and it is necessary to push the mine car, the electric push rod 8 operates to retract its telescopic shaft, and the drive rod 12 loses its pushing force on the push claw 10. At this time, the return spring 14 rebounds and applies force to the pressure plate 122 of the drive rod 12. The pressure plate 122 drives the force-applying column 121 back to the initial position, and the push claw 10 returns to the raised state, which facilitates connection with the wheel axle of the mine car and pushes the mine car. It is easy to adjust the push claw 10 to be in the horizontal or raised state. The adjustment of the horizontal or raised state of the push claw 10 is random, highly flexible, and can adapt to the ever-changing mine yard scheduling conditions.
