Problems solved by technology

At present, the type of elastic end stop is relatively simple. The most common is to set up mounds or sand piles at both ends of the track, tie the sleepers at both ends of the track, and fix springs or rubber piers on the rigid end stop. The structural reliability and stop effect are not ideal

Embodiment Construction

[0016] The present invention will be described below with reference to the accompanying drawings.

[0017] When the crane slides to the end of the track, the wheel touches the front baffle of the stopper and pushes the stopper to slide forward, so that the folding lock buckle slides along with it, and at the same time, the high-strength bolts on the folding lock buckle slide along the chute. Because the chute is inclined downward at a certain angle along the sliding direction of the high-strength bolts, the high-strength bolts slide and tighten the folded locks at the same time, the steel blocks of the rail will be locked tighter and tighter, and the pressure on the rails will be greater and greater. The frictional force received by the stopper is getting bigger and bigger, so as to achieve the thrust purpose.

[0018] The stopper is installed at the end of the track, and the bar-shaped steel block with a chute is fixed on both sides of the track. The high-strength bolts on th...

Abstract

The invention discloses a rail-mounted crane end stopper, which is installed at the end of a rail (11), and is characterized in that: the rail-mounted crane end stopper includes: a front baffle (10), an inclined Support (8), connecting plate (9), rail pressure steel block (1) and friction material (2); wherein, the upper part of the front baffle (10) and the upper part of the diagonal brace (8) are fixed by the connecting plate (9) , the lower part of the front baffle (10) and the lower part of the diagonal brace (8) are fixedly connected to the rail-pressing steel block (1), and the lower end of the rail-pressing steel block (1) is provided with a friction material (2). The invention is the last line of defense for the windproof braking of the crane, which enables the crane to brake safely.

Description

technical field [0001] The invention relates to an end stopper of a rail-mounted crane, which is mainly used for the stopper at the end of the track of rail cranes such as portal type, portal type, and shore bridge type, and is used as a part of the preventive and emergency windproof device for the crane. The last line of defense against wind when it fails. Background technique [0002] The track end stop device is a safety device arranged at the end of the track of the rail-mounted crane. It has the safety function of absorbing kinetic energy and reducing impact. It is the last line of defense against wind when the preventive and emergency wind protection devices of the crane fail . Due to the frequent occurrence of wind disaster accidents of rail-mounted cranes, many units have successively developed various auxiliary windproof devices, such as top rails, rail clamps, iron shoes, anchoring devices, etc. It has played a certain positive role, but these devices cannot comp...
