CN202243116U - Chain type automatic locking device of dump truck - Google Patents

Abstract

The utility model discloses the chain type automatic locking device of a dump truck, which comprises a lock hook seat fixed to the underframe of a compartment. A lock hook is prepared by bending a steel plate and is connected with the lower edge of the rear door of the dump truck through a pin shaft. The lock hook and the lock hook seat are connected with each other through a chain. According to the utility model, a chain is adopted by the device instead of a long pull bar, so that the easy deformation problem of the long pull bar is solved. Since the lock hook is prepared by a steel plate, the locking is firmer. The chain type automatic locking device of a dump truck has the advantages of simple structure, convenient reconstruction and good usage effect.

Description

Dumping car chain-type forced locking device

Technical field

The utility model relates to dumping car tail gate forced locking device.

Background technology

At present, most of dumping car tail gate latching devices all are to be connected on tail gate and the compartment underframe through the pull bar with Telescopic to form.This structure is comparatively complicated; And in the middle of long use, steel pull bar easy deformation, causing can't self-locking or lock insecurely, article spill in the car thereby cause, and cause unnecessary loss and waste; Use dumbly, have potential safety hazard.

The utility model content

The utility model problem to be solved provides a kind of on-deformable dumping car chain-type forced locking device.

Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of dumping car chain-type forced locking device; Comprise the lock hook seat that is fixed on the compartment underframe; Latch hook is processed for the bending steel plate, and latch hook is connected the tail gate lower edge through bearing pin, connects through chain between latch hook and the lock hook seat.

Described latch hook, lock hook seat, chain are symmetrically arranged two groups.

The utility model utilizes chain to replace long draw, has solved its yielding problem, and latch hook is that steel plate is processed, and locks more firm; Simple in structure, it is convenient to transform, and result of use is good.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

As shown in Figure 1, a kind of dumping car chain-type forced locking device comprises the lock hook seat 4 that is fixed on the compartment underframe 5, and latch hook 1 is processed for the bending steel plate, and latch hook 1 is connected tail gate 6 lower edges through bearing pin 2, connects through chain 3 between latch hook 1 and the lock hook seat 4.Parts wherein are symmetrically arranged two groups like latch hook, lock hook seat, chain etc.

Dumping car is when automatic unloaded of cargo, and the latch hook of tail gate is to utilize lever principle, and the back door promotes to open automatically down at the gravity of goods, when goods is unsnatched, and body of tipper carriage decline, latch hook is self-return under the pulling force of chain, with the tail gate auto lock.

Claims (2)

1. a dumping car chain-type forced locking device comprises the lock hook seat that is fixed on the compartment underframe, it is characterized in that: latch hook is processed for the bending steel plate, and latch hook is connected the tail gate lower edge through bearing pin, connects through chain between latch hook and the lock hook seat.

2. dumping car chain-type forced locking device according to claim 1 is characterized in that: described latch hook, lock hook seat, chain are symmetrically arranged two groups.
