Crane safety fastening device

Abstract

The invention discloses a crane safety fastening device which is characterized in that front concrete sleepers and rear concrete sleepers are sequentially arranged on the lower sides of steel rails, two anti-creeping fixtures are sequentially arranged on the left sides and the right sides of the steel rails respectively, clamp slots are formed in the upper ends of the anti-creeping fixtures, vertical screw holes are formed in the front and back sides of the anti-creeping fixtures, vertical distance adjusting lead screws are placed in the vertical screw holes, horizontal screw holes are formed in the left sides and the right sides of the anti-creeping fixtures, horizontal distance control screw rods are arranged in the horizontal screw holes, bases are arranged at the bottom ends of the steel rails, and the anti-creeping fixtures are clamped on the bases of the steel rails through the clamp slots. The crane safety fastening device is simple in structure and reasonable in design, the steel rails and the concrete sleepers can be locked into a whole after the anti-creeping fixtures are mounted, telescopic movement caused by vehicle passing and thermal expansion and contraction change of the steel rails is effectively controlled, stability of rail gaps of steel rail joints is ensured, daily maintenance workload is decreased, equipment safety risk is reduced, and the utilization rate of track lines is increased.

Description

Technical field [0001] The invention relates to a fixing device for a railway track, to be precise an anti-climbing fixture for track concrete sleepers. Background technique [0002] The hump line is the main feature of the railway marshalling station. It is a small hill built on the ground like the back of a camel, designed to adapt to the slope, and the railway is laid on it, using the potential energy generated by the gravity of the vehicle and the slope of the hump. A shunting device that is supplemented by locomotive thrust to break up trains is also the main method of breaking up trains and re-marshalling in a marshalling station. When the train runs on a ramp, it will have a longitudinal force with the rail, mainly friction force, which will cause the rail to shift longitudinally, and sometimes even drive the rail to move together. This phenomenon is called "track crawling". The hump line designed in the marshalling station is a continuous slope, with a maximum slope of 4...

AI Technical Summary

Problems solved by technology

When the crawling amount of the rail reaches 20mm, in order to ensure the safety of the equipment, it is necessary to carry out the correction and repair of the rail pulling uniformity, which not only affects the scheduling of the train in the marshalling station, but also consumes a lot of manpower and material resources
