Technical Field

The invention relates to a damping device for a falling frame of a dump truck after a hopper of the dump truck discharges.

Background

The tail end of a hopper of the underground ore-transporting truck is hinged with the tail end of the frame, a jacking mechanism is arranged between the front end of the hopper and the frame to jack the hopper, so that the tipping type discharging action of the hopper is realized, and the front end of the hopper is lapped on a supporting table surface of the frame supporting part when the jacking mechanism jacks and falls back. The jacking mechanism generally adopts an oil cylinder and utilizes the extension and retraction of a piston rod to complete the unloading and the falling. Because the underground ore-transporting truck runs in a rugged underground roadway for a long time, the hopper and the frame are made of rigid materials, the contact surface between the frame and the hopper is frequently impacted to accelerate the abrasion, the stable limit is not available, the hopper is easy to swing left and right or slide, and the hinge pin device of the frame is damaged to deform. If the oil cylinder is aged and the operation is unstable, the hopper can impact the plane of the frame when falling back.

For this reason, the patent document entitled "a shock pad for a cargo compartment of a mining dump truck" (document number CN105840730A) provides a technical solution, which includes a bottom plate (2) capable of being mounted on a frame, and a rubber pad (1) arranged on the surface of the bottom plate (2), wherein the rubber pad (1) is cast and molded on the bottom plate (2); the bottom plate (2) is provided with a plurality of bent feet (3), and the bent feet (3) extend into the rubber pad (1) and are integrally formed with the rubber pad (1). The scheme can solve the problem of alleviating the adverse effect of collision vibration on the vehicle, and the sliding state between the contact surface of the tipping bucket cargo compartment and the shock pad inevitably occurs in the constraint positioning between the shock pad and the tipping bucket cargo compartment, so that the service life of the shock pad is short, the shock pad needs to be frequently replaced, and meanwhile, the abrasion degree of a tilting hinge shaft rotating pair is not improved.

Disclosure of Invention

The invention aims to provide a limiting damping device of a hopper of an ore-transporting truck, which gives consideration to the damping between the hopper and a frame and avoids the sliding phenomenon between the hopper and the frame.

In order to achieve the purpose, the invention adopts the following technical scheme that a first seat and a second seat are respectively and correspondingly arranged on a hopper and a frame of a damping device of a hopper of an ore-transporting truck, and the damping device is characterized in that: the first seat and/or the second seat are/is provided with a shock pad, the first seat and the second seat form a fit type fit through the shock pad, and a limit fit for limiting the first seat and the second seat to slide along a fit surface is formed between the first seat and the second seat.

In the scheme, when the hopper is in a falling state, part of weight of the hopper is transmitted to the frame by the first seat and the second seat which are mutually attached and matched and is supported by the frame, and impact generated when the hopper falls is buffered by absorbing energy of the shock pad.

Detailed Description

Referring to fig. 1, a damping device for a hopper of an ore-carrying truck, a first seat 10 and a second seat 20 are respectively and correspondingly arranged on the hopper and a frame, a damping pad 30 is arranged on the first seat 10 and/or the second seat 20, the first seat 10 and the second seat 20 form a fitting type fit through the damping pad 30, and a limiting fit for limiting the sliding of the first seat 10 and the second seat 20 along a fitting surface is formed between the first seat 10 and the second seat 20.

The first seat 10 in the above solution can be connected to the bottom of the lifting end of the hopper when the hopper is inclined, and the second seat 20 is naturally arranged on the frame, or vice versa. The shock pad 30 is arranged between the hopper and the frame, so that the impact collision phenomenon can be buffered when the hopper falls back to the frame, and the phenomenon of direct rigid impact between the hopper and the frame is avoided. In addition, the limit fit between the first seat 10 and the second seat 20 limits the sliding between the two seats along the joint surface, namely, the swinging phenomenon of the hopper end, namely, the end far away from the tipping hinge shaft, in the vehicle width direction is limited. This contributes to an increase in the service life of the hinge shaft and the cushion 30, and also improves the stability of the vehicle during operation.

Preferably, the limit fit between the first seat 10 and the second seat 20 for limiting the sliding of the two seats along the abutting surface includes a rib 40 provided at the edge of the first seat 10 or the second seat 20, and the rib 40 extends toward the seat body on the opposite side and is blocked at the side of the seat body on the opposite side. In the above-mentioned solution, if the rib 40 is disposed on the first seat 10, when the rib 40 is engaged with the first seat 10, the rib is abutted against the side of the second seat 20, which is simple in structure and remarkable in limiting and restricting effect.

Preferably, the shock absorbing pad 30 is fixedly mounted on the second seat 20.

In the embodiment shown in fig. 1, the rim of the first seat 10 is provided with a rib 40 extending towards the side of the seat body of the second seat 20. The rib 40 is arranged on the first seat 10, so that the supporting table surface of the second seat 20 is ensured to be in a flush state as a whole, and the cleaning of collected dust or sundries on the supporting table surface is facilitated.

More preferably, the shock absorbing pad 30 is fixed to the shock absorbing pad plate 31, and the shock absorbing pad plate 31 and the second seat 20 form a detachable fixed connection. The shock pad 30 is a wearing part which is frequently stressed after all and needs to be replaced conveniently and timely, so that the shock pad 30 is conveniently disassembled and assembled with the second seat 20 in the form of a component fixedly connected to the shock pad plate 31, and even if the shock pad 30 body is damaged by crushing and the like, the shock pad plate 31 can be used for vulcanizing and replacing the shock pad 30 for later use.

In order to ensure and improve the limit constraint performance of the matching position of the hopper and the vehicle frame, limit guide strips 50 are respectively arranged on two sides of the opposite sides of the shock absorption backing plate 31. Namely, the limit guide strip 50 is arranged to realize the resisting fit with the flange 40, and the constraint fit is simple in structure and reliable.

The second seat 20 has a concave area surrounded by the protruding surrounding wall 21 for accommodating the assembly of the cushion pad 30 and the cushion pad 31, the cushion pad 31 and the bottom plate of the concave area are detachably connected, and the limiting guide strip 50 and the surrounding wall 21 on the opposite side are detachably connected. The above-mentioned peripheral wall 21, arranged in the vehicle length direction, constitutes a supporting abutment against the side of the cushion 30, ensuring the occurrence of severe deformations in this direction.

Referring to fig. 2, a spacer 60 is provided between the position-limiting guide strip 50 and the surrounding wall 21 on the opposite side. The first seat 10 matched with the first seat is provided with a flange 40 arranged in a splayed shape towards the opposite side, and the outer side surface of the limiting guide strip 50 is provided with an inclined surface matched with the flange 40.

The distance between the flanges 40 on the opposite sides is determined during welding and fixing during processing, how to ensure that a proper matching distance is formed between the side edges of the limiting guide strip 50 and the flanges 40 is adjusted by adding and subtracting a gasket 60 with proper thickness, so that the distance between the two flanges 40 and the limiting guide strip 50 on the corresponding sides is ensured to be in an optimal fit state, and after the limiting guide strip is used for a period of time, the size of a gap can be changed, therefore, the bolt 70 for connecting the limiting guide strip 50 and the surrounding wall 21 on the opposite sides is positioned in the horizontal direction, and the plate surface of the gasket 60 between the two flanges is E-shaped or U-shaped. When the adjusting is performed, the bolt 70 is loosened properly, so that the gasket 60 can be conveniently removed or inserted, the plate surface of the gasket 60 is E or U-shaped, and the plate surface can also be understood as a shape that one side of the strip-shaped gasket is provided with a U-shaped notch, and E can be understood as a structure formed by arranging a plurality of U-shapes in sequence.

The flanges 40 and the limiting guide bars 50 are located on both sides in the vehicle width direction. This is because the flanges 40 and the stopper guides 50 are disposed on both sides in the vehicle width direction to exert the most effective restriction and stopper in consideration that the tip-up and tip-up ends of the hopper can be regarded as free ends and there is a degree of freedom of swing in the vehicle width direction.
