Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of anti-collision, particularly relates to a kind of anti-collision limit stop. BACKGROUND
[0002] The dumper is a large-scale unloading equipment, mainly used for unloading the bulk material loaded in the railway open wagon, such as coal, ore, etc. It has high working efficiency and can realize rapid unloading, reducing the residence time of the vehicle at the unloading point. The dumper generally has various types such as rotor type and side tilting type. Among them, the rotor type dumper is widely used. It drives the vehicle to be fixed on the rotor by motor, and then rotates about 160-180 degrees to make the material fall into the underground storage facility.
[0003] The dolly is mainly used for pushing the railway vehicle to move along the predetermined route. In the dumper operation process, the dolly plays a key role in accurately pushing the vehicle into the dumper. In the combined working environment of the dumper and the dolly, the vehicle may exceed speed or deviate during the pushing process due to various reasons (such as equipment failure, control system error, etc.), which may easily cause collision between the vehicle and the dumper or other equipment.
[0004] In the prior art, the anti-collision measures for the dumper mostly rely on traditional physical barriers or manual monitoring. However, these measures have many shortcomings. Although the physical barrier can play a protective role to a certain extent, long-term hard collision can easily damage the equipment and shorten its service life. Manual monitoring has the problem of reaction lag, which makes it difficult to timely discover and avoid potential collision risks. INVENTION CONTENTS

In use, the first supporting rod and the second supporting rod are arranged at the lower part of the front end of the dolly. After the dolly pushes the railway open wagon into the dumper, the end of the dumper touches the trigger assembly, driving the stop block to separate from the adsorption assembly. The controller obtains the signal through the proximity switch, stops the dumper and the dolly from moving, avoids the damage to the equipment caused by the physical barrier, and has rapid reaction.
[0008] Preferably, the one end of the first supporting rod away from the proximity switch and the one end of the second supporting rod away from the triggering assembly are connected by a mounting rod.
