Referring to fig. 1 to 2, an embodiment of the present application provides a rear door opening mechanism for a dump truck, which includes a rear plate frame 1, a latch hook 3, a latch rod 6, and a rear plate side door 4. The upper end of the back plate frame 1 is hinged to the top of the end of the car hopper 7 through a supporting hanger 2, and the rotation axis of the back plate frame 1 is parallel to the horizontal plane. The latch hook 3 is arranged at the tail end of the car hopper 7, and the latch hook 3 acts on the back plate frame 1 and is used for locking the back plate frame 1. One side of the rear-plate side-opening door 4 is hinged to the rear-plate frame 1 through a side-opening door hinge 5, and the rotation axis of the rear-plate side-opening door 4 is perpendicular to the horizontal plane. The bolt rod 6 is arranged on the other side of the rear plate side door 4, and the bolt rod 6 is used for clamping the rear plate side door 4.

The rear plate frame 1 is hinged to the top of the tail end of the car hopper 7 by adopting the supporting hanging lug assembly 2, so that the rear plate frame 1 can be automatically opened under the action of self gravity when the car is in a tipping bucket, and the rear plate frame 1 can be locked by the lock hook 3 arranged at the tail end of the car hopper 7, so that the rear plate frame 1 is prevented from being opened in a non-unloading state. Meanwhile, the side door hinge 5 is adopted to hinge the rear plate side door 4 to the side face of the rear plate frame 1, so that the rear door of the dump truck can be opened laterally, when a large piece of goods is unloaded, the rear door can be opened laterally, and the dump truck is convenient to carry and is in butt joint with a ground station, and the working efficiency is greatly improved.

In detail, the back plate frame 1 includes a bottom beam and two side beams disposed at both sides of the bottom beam, the side beams are perpendicular to the bottom beam, the support hanger 2 is disposed at the top of the end of the hopper 7, and the top of the side beams is hinged to the hopper 7 through the support hanger 2. When the hopper 7 performs a tipping action, the back plate frame 1 is separated from contact cooperation with the hopper 7 under the action of self gravity, so that the back plate frame 1 is automatically opened to facilitate unloading. The lock hook 3 arranged at the bottom of the back plate frame 1 can lock the bottom beam of the back plate frame 1, so that the bottom beam is tightly matched with the hopper 7, and further, the material leakage in the hopper 7 caused by the automatic opening of the back plate frame 1 under the non-unloading state is avoided.

The back plate side door 4 is hinged on the back plate frame 1 by a side door hinge 5, and when the back plate side door 4 is in a closed state, the back plate side door 4 is in the back plate frame 1. When the back door needs to be opened laterally, only a force is given to the back plate side door 4, so that the back plate side door 4 rotates to one side around the side door hinge 5, and the side door opening action can be completed. Meanwhile, in order to prevent the rear-plate side door 4 from opening in a non-cargo loading and unloading state, a bolt 6 is arranged on the rear-plate side door 4 far away from the side door hinge 5, and the rear-plate side door 4 is locked by the bolt 6.

In one embodiment, the support tab assembly 2 comprises a support tab 21, a tab 22. The support lugs 21 are arranged at the top of the tail end of the car hopper 7. One end of the hanging lug 22 is hinged on the supporting lug 21 through a first pin shaft 23, and the other end of the hanging lug 22 is connected with the back plate frame 1. When the back plate frame 1 is opened, the back plate frame 1 rotates anticlockwise around the first pin shaft 23 in cooperation with the hanging lugs 22, so that the back plate frame 1 is far away from the hopper 7, and then the back plate frame 1 and the back plate side opening door 4 are rotated upwards to be opened, and materials in the hopper 7 can be discharged conveniently. In one embodiment, a washer is sleeved on one side of the first pin 23, and a cotter pin is arranged on the first pin 23 outside the washer.

In one embodiment, the latch hook 3 includes a latch hook seat 31, a latch block 32. The latch hook seat 31 is provided at the bottom of the end of the hopper 7. The locking piece 32 is hinged on the locking hook seat 31 through a second pin 33, a locking hole 321 is arranged on the locking piece 32, and the locking piece 32 acts on the rear plate frame 1. Referring to fig. 2 and 5, the latch hook seat 31 is fixed on the hopper 7 in advance, the latch block 32 is hinged on the latch hook seat 31 through the second pin shaft 33, and when the back plate frame 1 needs to be locked, the latch block 32 only needs to be rotated anticlockwise, so that the latch block 32 is tightly attached to the back plate frame 1, and meanwhile, the latch block 32 is inserted into the latch hole 321 in the latch block 32 through a pin, so that the position of the latch block 32 is fixed, and the back plate frame 1 is clamped by the latch block 32. When the back plate frame 1 needs to be released, only the pin in the locking hole 321 needs to be removed.

In one embodiment, the latch 6 includes a catch block 61, an L-shaped catch bar 62. The clamping block 61 is arranged on the rear plate side door 4, and the clamping block 61 is provided with a clamping groove. One end of the L-shaped clamping rod 62 is rotatably connected to the back plate frame 1, and the L-shaped clamping rod 62 is clamped and matched in the clamping groove of the clamping block 61. Referring to fig. 1, the horizontal portion of the L-shaped clamping rod 62 is rotatably disposed on the back plate frame 1, the hanging angle of the L-shaped clamping rod 62 is clamped in the clamping slot, the vertical portion of the L-shaped clamping rod 62 blocks the clamping block 61, so as to prevent the clamping block 61 from rotating around the side door opening hinge 5, and further achieve the purpose of locking the back plate side door opening 4. When unlocking is needed, only the L-shaped clamping connection rod 62 is required to be rotated, so that the vertical part of the L-shaped clamping connection rod 62 does not block the clamping block 61.

In one embodiment, a number of reinforcement plates 41 are provided on the back plate side opening door 4.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
