Description

Grab stone cleaning machine between sleepers

technical field

The invention relates to a railway machine, in particular to a stone cleaning machine with a grab bucket between sleepers.

Background technique

During the long-term use of railway sleepers, due to natural settlement and vibration, some railway sleepers sink and need to be maintained. Individual sleepers are damaged and need to be replaced in time. In the process of maintenance or sleeper replacement, it is necessary to clean the sleeper gravel between roadbeds. In the past, the subgrade rubble was manually cleaned, which was time-consuming and laborious, and the efficiency was low, and the work could not be completed within the effective train passage gap (commonly known as: skylight).

Contents of the invention

The purpose of the present invention is to provide a grab stone cleaner between sleepers, using the grab stone cleaner between sleepers to clean roadbed gravel, saving time and labor, and high working efficiency.

The present invention is composed of a rail car, a generator, an operation control box (with a fuel tank, an oil pump and various control valves inside), and a grab stone cleaning device. Moving, the generator, control operation box and grab stone cleaning device are set on the rail car, the generator provides power for the oil pump, and the grab stone cleaning device is composed of a beam, trolley, rotary table, lifting basic arm, lifting telescopic Boom, jib luffing cylinder, portal steel frame, grab opening and closing cylinder, afterburner plate, strut, grab, trolley moving drive cylinder, slewing support bearing and sector gear set, the beam is fixed on the railcar Above, guide rails are set on the front and rear sides of the beam, the trolley is located on the beam, the casters set on the trolley are placed in the guide rails on the beam, and the oil cylinder driving the trolley is set on the left side of the beam, and the outer end of the piston rod of the cylinder is in contact with the platform. The car is hinged, the piston rod of the oil cylinder is stretched to realize the movement of the trolley, the trolley and the slewing table are connected through the slewing support bearing, the oil motor meshes with the upper ring gear of the slewing support bearing to realize the rotation of the slewing table, and the basic lifting arm is articulated on the slewing table to lift The jib luffing cylinder is hinged between the front end of the basic arm and the slewing table, the lifting telescopic arm is set in the lifting basic arm, and the lifting telescopic arm is hinged between the lifting telescopic arm and the lifting basic arm by the cylinder piston The movement of the rod realizes expansion and contraction in the basic lifting arm; the front end of the lifting telescopic arm is hinged to the door-type steel frame, and the two sides of the door-type steel frame are symmetrically hinged to a pair of grab opening and closing cylinders, which are fixed to the piston rod of the grab opening and closing cylinder The reinforcement plate at the lower end is hinged with the buckets on both sides of the grab, the struts are respectively hinged with the buckets and the door-type steel frame on both sides of the grab, and the sector gear sets are fixedly connected to the buckets on both sides of the grab.

Working process and principle of the present invention are as follows:

The generator provides power for the oil pump, and the oil pump provides high-pressure oil. The rail car can be moved on the track with the help of manpower. The grab stone cleaning device installed on the trolley can move freely laterally by pushing and pulling the oil cylinder; the rotary table can move freely through the oil motor. Rotation; the lifting basic arm on the slewing table realizes the luffing by means of the lifting arm luffing cylinder, and the lifting telescopic arm moves in the lifting basic arm by means of the movement of the cylinder piston rod hinged between the lifting telescopic arm and the lifting basic arm. Telescopic: The symmetrically arranged double grab buckets suspended on the portal steel frame can be opened and closed through the action of the grab opening and closing cylinder, the afterburner plate and the support rod to release and grab gravel. Synchronous opening and closing is achieved by the meshing of sector gear sets.

The beneficial effects of the present invention are: the grab stone clearing device can be translated, lifted and rotated, and can quickly remove the gravel between the two sides of the sleeper. It is not only easy to operate, reliable in performance, high in mechanized operation rate, but also simple in structure and light in weight for two people. The complete machine can be lifted off the track conveniently, and the limited operating time for line repair "skylight" can be fully and rationally utilized.
