Description

Technical Field

[0001] The utility model relates to the technical field of pushers, in particular to a multifunctional device for pushing a mine car. Background Art

[0002] Pin-toothed trolley pushers are auxiliary trolley pushers widely used in the transportation of mine carts in mines. They replace manual trolley pushers and greatly reduce the labor intensity of on-site workers. Pin-toothed trolley pushers mainly include driving pin gears, pin-toothed chain links, trolley links and slideways. The slideways are arranged in the middle of the track on which the mine cart runs. The trolley links are connected through pin-toothed chain links and arranged in the slideways. The pin gears are meshed with the pin-toothed chain links. The driving pin gears are rotated to drive the pin-toothed chain links to drive the trolley links to move in the slideways. The axles of the mine carts are blocked by the blocking heads or push claws arranged on the trolley links, thereby pushing the mine carts to run.

[0003] At present, most of the push-grabbing structures of the existing cart pushers can basically only perform one-way cart pushing operations, such as the push-grabbing structure in patent number CN114852123A. This kind of single-phase cart pusher usually needs to be equipped with two slideways. When the mine car reverses and returns, it needs to be transferred to another slideway for rotation. However, in some narrow lanes, it is impossible to install double lanes, and the mine car can only be pulled back manually. Therefore, the use of one-way carts is limited and the efficiency is low.

[0004] Another example is the pusher machine that can push carts in both directions in patent numbers CN117622251A and CN108639919A. Its basic principle is to set two opposing push grips on the pusher section, and the mine cart axle is stuck between the two push grips, so as to achieve the two-way pushing of the mine cart that can both push and pull the cart, thereby improving the application scope and convenience of the pusher machine. However, the two push grip structures of such a two-way pusher machine are usually more complicated, require more parts, are costly and easy to damage; and setting two push grips on the pusher section also requires increasing the length of the pusher section, further increasing the manufacturing cost. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a cart pusher with a two-way connection resistance which can both push and pull a cart, and has the advantages of simple and durable structure and low cost.

[0006] The utility model is realized through the following technical scheme: a mine cart pusher machine-resistance multifunctional device, comprising a pusher section and a push plate, wherein the center of the push plate in the length direction is rotatably connected to the top of the pusher section, a driving mechanism for driving the push plate to rotate is fixedly arranged on the pusher section, the mine cart axle height of the mine cart is higher than the height of the rotation center of the push plate, and the mine cart axle is located on the rotation path of the push plate, a semicircular groove is opened on the top of the pusher section, the semicircular groove is adapted to the rotation path of the push plate, a limit column is arranged in the semicircular groove, and the limit column is located on the rotation path of the push plate.

[0007] The push plate described in this solution rotates around the center to form a circular rotation path. Since the height of the mine cart axle is higher than the height of the push plate's rotation center, when the push plate rotates to a horizontal state, the push cart can pass under the mine cart axle in an energy-saving manner. The moving path of the mine cart axle is located on the rotation path of the push plate. By driving the push plate to rotate forward and backward, the two sides of the push plate's rotation center can respectively block the mine cart axle. When one end of the push plate is pushing the mine cart, the mine cart will provide a force in the opposite direction to the push plate, and the limit column will limit the other end of the push plate to provide a supporting force to prevent the push plate from rotating and becoming disconnected from the mine cart, thereby realizing the functions of pushing and pulling the cart. This solution realizes two functional structures of pushing and pulling the cart through the forward and reverse rotation of a push plate, and the structure is simple and durable, with the advantages of easy maintenance and low cost.

[0008] As an optimization, the center of the semicircular groove and the rotation center of the push plate are coaxially arranged, and the radius of the semicircular groove and the rotation radius of the push plate are adapted. This optimization scheme reduces the height of the rotation center of the push plate by setting a semicircular groove, so that the push plate is half hidden in the semicircular groove, optimizes the product structure, and makes the structure more beautiful.

[0009] As an optimization, both ends of the push plate in the length direction are arc surfaces. This optimization solution facilitates the push plate to rotate in the semicircular groove, so that the end of the push plate is more closely fitted with the circular surface of the semicircular groove.

[0010] As an optimization, the limit column can be detachably installed in the semicircular groove. This optimization solution is convenient for personnel to disassemble, use and replace.

[0011] As an optimization, two limit grooves are provided on the same side end surface of the push plate, and the two limit grooves are symmetrically arranged on both sides of the rotation center of the push plate, and the limit column and the mine car axle are both located on the rotation path of the limit groove. The limit groove of this optimization solution engages the mine car axle, limits the axle, makes the connection between the push plate and the axle more stable, and further prevents the axle and the push plate from being disconnected.

[0012] As an optimization, the limit groove is an arc groove. The arc groove of this optimization solution is convenient for fitting with the circular axle.

[0013] As an optimization, the driving mechanism is a driving motor, a hinge shaft is fixedly connected at the center of the push plate in the length direction, the push plate is hinged to the pusher section through the hinge shaft, and the output end of the driving motor is fixedly connected to one end of the hinge shaft. This optimization scheme drives the hinge shaft to rotate through the driving motor to realize the forward and reverse rotation of the push plate.

[0014] The beneficial effects of the utility model are as follows: the solution realizes two functional structures of pushing and pulling carts by setting a push plate on the cart section, and continuously blocking the axle of the mine cart through the forward and reverse rotation of the push plate. Compared with the cart pusher that can only push carts in one direction, the application range is wider and the efficiency is higher. Compared with the existing cart pusher that pushes carts in both directions, the structure of the present application is novel, simple and durable, and has the advantages of easy maintenance and low cost.

[0015] The push plate is half hidden in the semicircular groove, which optimizes the product structure and makes it more beautiful. The push plate is supported by the limit column in the semicircular groove, and the push plate is engaged with the mine car axle through the limit groove to prevent the push plate from rotating and being out of touch with the mine car, which greatly improves the stability of use.

[0025] The pin-toothed trolley machine mainly includes a driving pin gear, a pin-tooth chain link, a trolley section 1 and a slideway 8. The slideway 8 is arranged in the middle of the track 7 on which the mine car 5 runs. The trolley section 1 is connected and arranged in the slideway 8 through the pin-tooth chain link. The pin gear is meshed with the pin-tooth chain link. The driving pin gear rotates to drive the pin-tooth chain link to drive the trolley section to move in the slideway. The trolley axle 51 of the mine car is blocked by the blocking head or the pushing claw arranged on the trolley section 1, so as to realize the operation of pushing the mine car 5. Usually, the top surface of the trolley section 1 and the track 7 are located on the same horizontal plane. The mine car 5 moves on the track 7, which is convenient for the push grip to contact the trolley axle 51. The push grip of the existing trolley section can only push the trolley in one direction with a single function, or the structure is complicated, the manufacturing cost is high and it is not convenient for maintenance. For this reason, the present application provides a trolley machine that can push the trolley in both directions and has a simple and durable structure.

[0026] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0027] like Figures 1 to 7 As shown, a mine cart pusher machine-resistance multifunctional device comprises a pusher section 1 and a push plate 2. The push plate 2 is rotatably connected to the top of the pusher section 1 at the center of the length direction. A driving mechanism for driving the push plate 2 to rotate is fixed on the pusher section 1.

[0028] Specifically, a hinge shaft 22 is fixedly connected at the center of the push plate 2 in the length direction, and the push plate 2 is hinged and rotated with the pusher section 1 through the hinge shaft 22. The driving mechanism is a driving motor 6. The driving motor 6 in this embodiment is a servo motor, which can drive the push plate 2 to rotate forward and reverse. The output end of the driving motor 6 is fixedly connected to one end of the hinge shaft 22.

[0029] The push plate 2 rotates around the hinge shaft 22 to form a circular rotation path, and a semicircular groove 3 adapted to the rotation path is opened on the top of the push car section 1. The center of the semicircular groove 3 is coaxially arranged with the rotation center of the push plate 2, and the radius of the semicircular groove 3 is adapted to the rotation radius of the push plate 2. In order to facilitate the rotation of the push plate 2 in the semicircular groove 3, the two end surfaces of the push plate 2 in the length direction are arc surfaces.

[0030] The height of the mine car axle 51 of the mine car is higher than the height of the rotation center of the push plate 2. When the push plate 2 rotates to a horizontal state, the push car section 1 can pass under the mine car axle 51. The mine car axle 51 is located on the rotation path of the push plate 2. When the push plate 2 rotates and stands upright, the push plate 2 can contact the mine car axle 51, and the push plate 2 is driven to rotate forward and backward, thereby realizing the function of pushing and pulling the car.

[0031] A limiting column 4 is provided in the semicircular groove 3, and the limiting column 4 is also located on the rotation path of the push plate 2. Specifically, the limiting column 4 is detachably installed in the semicircular groove 3, and the limiting column 4 is arranged just below the rotation center of the push plate 2. The limiting column 4 in this embodiment is a bolt, which is inserted into the semicircular groove 3 and is screwed and fixed to the cart section 1 by a fastening nut.

[0032] Two limit grooves 21 are provided on the same side end surface of the push plate 2, and the two limit grooves 21 are symmetrically arranged on both sides of the rotation center of the push plate 2. The limit column 4 and the mine car axle 51 are both located on the rotation path of the limit groove 21. The limit groove 21 is an arc groove, which is convenient for fitting with the circular mine car axle and the limit column.

[0033] Working principle: When the pusher section 1 pushes the cart forward, the pusher section 1 first moves to the rear of the mine cart 5, and the driving motor 6 drives the push plate 2 to rotate forward and stand upright, so that the side of the push plate 2 with the limit groove 21 faces the mine cart axle 51, and the pusher section 1 moves forward, so that the mine cart axle 51 is engaged in the limit groove 21, thereby pushing the mine cart 5 to move forward.

[0034] When the cart segment 1 needs to pull the cart backward, the push plate 2 is driven to reverse to a horizontal state, the cart segment 1 moves to the front of the mine cart 5, and the push plate 2 is driven to continue to reverse and stand up, so that the side of the push plate 2 with the limiting groove 21 faces the mine cart axle 51, and the cart segment 1 moves backward, so that the mine cart axle 51 is engaged in the limiting groove 21, thereby pushing the mine cart 5 to move backward.

The technical features not described in the present invention can be achieved by or by adopting the existing technology, which will not be repeated here.
