Description
Technical Field
The utility model belongs to the technical field of the mine car, specifically speaking relates to a multi-link formula mechanism that opens and shuts for mine car.
Background
The underground mine car is mainly used in underground mines, mainly for loading, transporting and dumping, and is suitable for operation surfaces with severe working conditions, narrow and low operation sites and muddy operation. When the mine car works in the tunnel, the mine car is limited by the working environment, self-discharging cannot be completed, manual unloading is needed, and the mine car is manually pushed to overturn the carriage for ore discharging, so that the working efficiency is low, and the labor intensity is high. When the carriage is in a horizontal state, a gap is formed between the striker plate and the carriage, the striker plate cannot be closed tightly, and mineral leakage is easily caused; when the mine car travels, the rear door is not closed tightly, and the mine car can collide with the carriage to generate strong noise. Meanwhile, as the operators stand beside the turnover mine car to unload the mine, a large amount of dust generated during unloading the mine can seriously damage the health of the operators. Moreover, the operation personnel work near the well head of the ore sliding shaft, and have the danger of falling into the well, have great potential safety hazard.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the following description, together with the drawings of the present invention, clearly and completely describes the technical solution of the present invention, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without creative efforts shall all belong to the protection scope of the present application. In addition, directional terms such as "upper", "lower", "left", "right", etc. in the following embodiments are directions with reference to the drawings only, and thus, the directional terms are used for illustrating the present invention and not for limiting the present invention.
The present invention will be further described with reference to the accompanying drawings and preferred embodiments.
The first embodiment is as follows:
as shown in fig. 1 and 2, a multi-link type opening and closing mechanism for unloading mine is located above a frame 7, the opening and closing mechanism comprises a link assembly, a striker plate 3 and a back door pull rod 2, the link assembly comprises a first link 6 and a second link 5, the head end of the first link 6 is hinged with the tail end of the second link 5, the tail end of the first link 6 is fixed on a fixing groove 8 of the frame 7, the head end of the second link 5 is movably connected with the back door pull rod 2, the back door pull rod 2 is formed by extending from the top end of the striker plate 3 to the front direction of the frame, the striker plate 3 is located at a discharge opening of the carriage 1, the middle part of the back door pull rod 2 is rotatably connected with the outer wall of the carriage 1, when the carriage 1 is in a lifting and discharging state, the link mechanism pulls the striker plate 3 to cause an opening for material to fall to be formed between the striker plate 3 and the discharge opening of the carriage, when the, the back door pull rod 2 is closed with the striker plate 3.
As shown in fig. 2, when the carriage 1 is in a reset state, i.e. the tramcar is in a normal loading and transporting stage, the striker plate 3 is positioned at the discharge opening of the carriage 1 and the carriage 1 is wholly closed for convenient transportation; when the mine car travels to the freight destination and starts the unloading operation, the car 1 starts to perform the lifting and unloading action under the action of the hydraulic lifting column 4, because the front end of the rear door pull rod 2 is connected to the frame 7 by the connecting rod assembly, under the combined action of the lifting force of the carriage 1, the gravity of the front end and the rear end of the rear door pull rod and the pulling force of the connecting rod assembly, the rear door pull rod 2 is necessarily pulled by the connecting rod assembly and cannot synchronously act with the carriage 1, thereby causing the initial closing state between the rear door pull rod 2 and the port of the carriage 1 to be changed into the gradual occurrence of a fit clearance between the two, the carriage 1 continues to lift, the clearance between the striker plate 3 and the port of the carriage 1 is finally pulled by the pull rod mechanism to reach the degree of sufficient unloading, the automatic discharging device has the advantages that discharging operation is achieved, extra auxiliary discharging elements are not needed in the whole process, the whole process is automatic and convenient, work is safe and reliable, the structure is simple, and discharging efficiency is high.
In the embodiment, in order to pursue the unloading stability of the mine car, the connecting rod assemblies are symmetrically arranged on the outer wall of the carriage 1, meanwhile, the hydraulic lifting columns 4 arranged on the outer wall of the carriage 1 are hinged to the frame 7, and the piston rod ends of the hydraulic lifting columns are respectively pressed and hinged to the outer wall of the carriage 1, so that the force application balance of the connecting rod assemblies on the mine car is guaranteed when the carriage 1 is lifted, and finally the working performance of the connecting rod assemblies meets the actual requirement.
In order to realize the rotating connection relationship between the carriage 1 and the rear door pull rod 2, a pin shaft and a pin hole are arranged at the matching position of the outer wall of the carriage 1 and the rear door pull rod 2, and the pin hole and the pin shaft are arranged at the corresponding position on the rear door pull rod 2 and form rotating connection matching between the pin shaft and the pin shaft; considering that the direct fit between the pin hole and the pin shaft is necessarily accompanied with a large amount of friction and abrasion phenomena, a wear-resistant sleeve is clamped between the pin hole and the pin shaft, so that the service life of the wear-resistant sleeve is prolonged. Therefore, the phenomenon that the hinged point is broken by the ore due to the fact that the ore normally enters the bucket when the forklift truck is stopped for loading is avoided, the whole structure is compact, the operation is reliable and stable, and the market prospect is wide.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
