Automatic locking and unlocking device for container dumper undercarriage

Abstract

The invention provides an automatic locking and unlocking device for a container dumper undercarriage. The automatic locking and unlocking control of an undercarriage lock is realized in a pure mechanical mode, and the automatic locking and unlocking device for the container dumper undercarriage has a simple structure and is safe and reliable, and man-machine separation can be realized. The automatic locking and unlocking device for the container dumper undercarriage comprises a bulb connecting rod, a pull rod and a mechanical touch device, wherein the touch device comprises a first touch body, a spring and a second touch body; the second touch body is fixedly arranged on a frame and is correspondingly arranged with the first touch body; the upper surface of the second touch body is an advancing slope; the bottom end of the first touch body is provided with an idler wheel which can roll on the advancing slope; two ends of the pull rod are respectively connected with the undercarriage lock and the bulb connecting rod; the other end of the bulb connecting rod is connected with the top end of a first collision body; the top end of the first collision body is connected with the spring; and when the undercarriage is lifted to a set position, the spring drives the bulb connecting rod to move with the first touch body so as to pull the pull rod to drive the undercarriage lock to rotate to an unlocking position or a locking position. The automatic locking and unlocking device for the container dumper undercarriage has the advantages of simple structure, convenience in installing and debugging, and low construction price, and can be applied to various types of container dumpers.

Description

technical field [0001] The invention belongs to the field of dump trucks for container bulk cargo unpacking, and in particular relates to an automatic switch lock device for a container dump truck. Background technique [0002] In the unpacking and unloading process of bulk containers, container dump trucks play an extremely important role. On current container dump trucks, in order to prevent the container from slipping off from the chassis of the dump truck during unloading, it is usually necessary to install a chassis lock on the chassis of the dump truck to fix the container placed on the chassis. At present, most container dump trucks use hydraulic or pneumatic switch locks for their discs, which are expensive to manufacture and prone to failures, which are not conducive to energy saving and emission reduction, and are difficult to maintain; there are also manual methods to switch the disc locks, which have low work efficiency and cannot be used. Realizing the separati...

Problems solved by technology

At present, most container dump trucks use hydraulic or pneumatic switch locks for their discs, which are expensive to manufacture and prone to breakdowns, which is not conducive to energy saving and emission reduction, and are difficult to maintain; there are also manual methods to switch the disc locks, which have low work efficiency and cannot be used. Realize the separation of man and machine, it is difficult to guarantee the requirements of production and personal safety

If the container is unloaded without being locked due to human error, there is a potential danger of the container falling over, the container being damaged, and the vehicle being damaged. It is difficult to ensure the requirements of production safety and personal safety.
