Abstract

The invention relates to a locking bolt lock-up mechanism which comprises a base, an oil cylinder, a locking bolt and a piston rod, wherein the base is arranged on a vehicle body; the oil cylinder is arranged on the base; the locking bolt is arranged in a hole of the base; a limiting pin, a press plate, a piston column and a tab washer are arranged on the locking bolt; the head of the oil cylinder is connected with the piston column; the press plate is connected with the piston column through a bolt; the piston rod is in threaded connection with the piston column; a limiting block and a screw plug are arranged on the base; and a spring is arranged between the limiting block and the screw plug. The locking bolt lock-up mechanism provided by the invention is simple, safe, and high in reliability; the problem that a taper pin is retracted due to vibration and impact can be solved; and a vehicle can be protected from accidents during a high-speed driving process.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a locking bolt locking mechanism which can be used on crawler engineering vehicles. Background technique [0002] Existing crawler engineering operation vehicles adopt a mechanical spring taper pin limit locking mechanism. When the locking bolt is in the non-working state, the tapered pin under the action of the spring pushes into the corresponding tapered hole of the locking bolt to realize the position locking of the locking bolt. When this mechanism is running at high speed, the tapered pin will retract due to vibration and impact, causing the locking bolt to fall off, resulting in vehicle failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies, provide a locking mechanism with simple structure, safety and high reliability, which solves the problem of tapered pin retraction caused by vibrat...
