Description

A kind of Catherine wheel mechanism applied to mine operation vehicle

Technical field

The utility model relates to dumper technical field more particularly to a kind of mine operation vehicle automatic unloading equipment, in particular to A kind of Catherine wheel mechanism applied to mine operation vehicle.

Background technique

It is well known that heavy-duty tipper, which has rollover to turn over two kinds with after, dumps form, the heavy-duty tipper for then turning over form is big Mostly use telescopic Multi-stage cylinder forward type lifting mechanism.Compared with middle lifting mechanism, there are vehicles for forward type lifting mechanism Center of gravity is higher, is easy to roll the shortcoming of rollover in lifting process, however common mine operation vehicle is due to being worked The influence of environment belongs to the relatively high vehicle in chassis on lesser body structure, is mainly set in using forward type at present Formula mainly uses rear turning type in order to avoid overturning.

Current rollover mechanism primary structure is the wagon box being hinged at chassis of vehicle body, is connected to wagon box bottom and chassis On lifting cylinder, and be mounted on the support leg of tray bottom, the use of support leg is primarily to improve chassis of vehicle body steady It is qualitative, the rollover that vehicle during cargo is toppled in rollover is placed, although which can be improved stability and place rollover, but simultaneously The troublesome operation in inclination cargo overshoot is increased, mine operation vehicle is mainly used for the rapid transport of coal or other ores, has It is swift in motion, mineral are needed rapid dump after mine transfer, then transported again, speed by the feature flexibly moved The advantages of degree and efficiency are substitution conventional rails transports, if increasing support leg in bottom, before coming down in torrents using traditional rollover mechanism The fixation for needing first to carry out bottom support leg, is then coming down in torrents, then increases the time come down in torrents, low efficiency, mine operation vehicle significantly Flexibly, feature quickly can not embody.

But in order to meet the needs of use space, it is mesh that rollover, which can reduce the height of wagon box during cargo comes down in torrents, What preceding mine operation vehicle needed, so mine operation vehicle Catherine wheel mechanism, and patent protection are researched and developed in my company's design.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of application for existing deficiencies in the technology In the Catherine wheel mechanism of mine operation vehicle, which can be realized wagon box rollover, reduce tipping bucket lifting Height can fast implement coming down in torrents for cargo, and the bottom supporting mechanism without the large-scale rollover vehicle of tradition, significantly drop shorten Unloading time improves the utilization rate of vehicle, and mine operation vehicle is flexible, quick operation mode embodies, and mine operation vehicle sheet Body stability is good, can arbitrarily topple in core carrying capacity allowed band, not will lead to the rollover of carbody.

The technical solution of the utility model is to provide a kind of following Catherine wheel mechanism applied to mine operation vehicle, Including being hinged at the wagon box on chassis of vehicle body, the chassis includes the body pillar frame for carrying wagon box, the body pillar Base of frame is equipped with floor stringer, and the floor stringer is welded on chassis of vehicle body, is equipped with and rises between the floor stringer and wagon box bottom Oil cylinder drops, and the lifting cylinder bottom and floor stringer are hinged, the lifting cylinder bottom and the hinged stress point of floor stringer and operation Level where the shaft of vehicle bottom wheel is consistent.Using the technical program, under the lifting cylinder bottom supporting point It moves, reduces the center of gravity point in lifting process, improve roll stability.

Preferably, the floor stringer bottom plane is located at wheel rear axle top.Guarantee that bump is not in vehicle driving It can be impacted with vehicle bottom chassis.

Preferably, the floor stringer is the frame body being welded by steel pipe or steel plate, the frame body includes two, The three or four vertically arranged connecting rods connecting with vehicle bottom chassis, the connecting rod bottom are welded with for disposing lifting oil The mounting platform of cylinder, the mounting platform are equipped with cylinder installation seat.

Preferably, the wheel rear axle is connect by damping spring plate with the floor stringer of chassis of vehicle body bottom.Connection is strong Degree is high, combines bearer connection operation, using effect is good.

Preferably, the lifting cylinder is two, it is separately positioned on chassis of vehicle body front and rear sides.

Preferably, the side that the chassis of vehicle body is hinged with wagon box is equipped with two supports being generally aligned in the same plane with chassis The outer ledge of side arm, the wagon box and support side arm is hinged.

Preferably, the cylinder installation seat is located at side of the floor stringer far from support side arm.

Preferably, the distance between articulated shaft of hinged wagon box and total width on the oil cylinder seat and support side arm The ratio between be 5 ~ 6:9.

Preferably, height of the wagon box hinged place apart from ground is 0.9-1m, total width 1.8-2m, wagon box maximum Tilt angle is 45 °.

Using the technical program the utility model has the advantages that the mine operation vehicle Catherine wheel mechanism can be realized wagon box rollover, reduction Tipping bucket adjustable height can fast implement coming down in torrents for cargo, and the bottom supporting mechanism without the large-scale rollover vehicle of tradition, significantly Drop shortens unloading time, improves the utilization rate of vehicle, and mine operation vehicle is flexible, quick operation mode embodies, and mine Operation Van stability itself is good, can arbitrarily topple in core carrying capacity allowed band, not will lead to the rollover of carbody.
