Abstract

The invention discloses a rear door locking device of a self-unloading muck truck and relates to the technical field of special vehicle manufacturing. The rear door locking device comprises a lock hook used for locking a rear door, wherein the rear door is hinged to the upper portion of a compartment, the lock hook is connected with a rigid linear reciprocating mechanism installed at the bottom of the compartment, and the motion direction of the linear reciprocating mechanism is the same as the width direction of the compartment; a lock catch capable of being buckled with or separated from the lock hook is arranged at the bottom of the rear door; a sealing rubber strip in press fit with the rear door is fixed to the tail of the compartment. The problems that an existing rear door locking device of the self-unloading truck loses efficacy easily, and a rear door is not sealed tightly are solved.

Description

technical field [0001] The invention relates to the technical field of special automobile manufacturing, in particular to a device for locking the rear door of a self-unloading muck truck. Background technique [0002] What existing self-unloading type slag car rear door adopted is chain self-locking, and chain one end is fixed with vehicle tail, and the other end is connected with compartment tail lock hook, and lock hook is connected with compartment with bearing pin, can rotate freely. Its working principle is: under the action of the power source, the compartment rotates and rises through the turning pin at the bottom, the distance between the chain and the rear door lock hook at the rear of the compartment becomes shorter, the lock hook opens automatically under the action of its own weight, and the rear door panel passes through the turning pin on the top of the compartment between its own weight and the compartment. Under the action of the goods inside, it will open i...
