Abstract
The utility model discloses a kind of novel dump lorry back doors, the self-discharging vehicle backdoor is successively composed of buffer layer, door-plate layer and support frame from inside to outside, the buffer layer is bolted on together with door-plate layer, the door-plate layer and support frame link together by welding, the main reinforcing rib is welded on the outside of door-plate layer in matrix pattern, the assistant reinforcement muscle is welded between main reinforcing rib, forms triangular structure between the main reinforcing rib and assistant reinforcement muscle.The utility model dumper by buffer layer, door-plate layer and supporting framework at; buffer layer and dumper touching position are using thickening design, it is ensured that the leakproofness between dumper when back door is closed, prevent cargo unrestrained; and buffer layer can also protect door-plate layer, avoid its abrasion；Support frame is made of main reinforcing rib and assistant reinforcement muscle, triangular structure is formed between main reinforcing rib and assistant reinforcement muscle, stability is good, practical.
Description
Technical field
The utility model relates to dumper accessory technical field, especially a kind of novel dump lorry back door.
Background technique
Dumper refers to the vehicle that cargo is voluntarily unloaded by hydraulic or mechanical lift, mainly by automobile chassis, hydraulic
The components such as lifting mechanism, container and power takeoff composition.Dumper is used primarily in building field, field of food etc. at present, can be with
Sandy soil, sand, stone, grain etc. are transported, due to the particularity of applying working condition and contained cargo, determines that container back door must have
Higher intensity and preferable leakproofness.The back door of existing dumper exist in use the compartments of some problem dumpers with
Leakproofness between back door is poor, and goods carried are easy to fall；In addition, the intensity of existing self-discharging vehicle backdoor is general, make for a long time
With easily deforming.
Utility model content
In order to overcome the defect in the presence of the prior art, the utility model provides a kind of novel dump lorry back door.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of novel dump lorry back door, it is described from
Back door of unloading successively is composed of buffer layer, door-plate layer and support frame from inside to outside, and the buffer layer is equipped with counter sink, institute
It states position corresponding with counter sink on door-plate layer and is equipped with threaded hole, the buffer layer and door-plate layer are bolted on one
It rises, the door-plate layer and support frame link together by welding, and support frame as described above includes that main reinforcing rib and auxiliary add
Strengthening tendons, the main reinforcing rib are welded on the outside of door-plate layer in matrix pattern, and the assistant reinforcement muscle is welded between main reinforcing rib,
Triangular structure is formed between the main reinforcing rib and assistant reinforcement muscle.
A kind of above-mentioned novel dump lorry back door, the arranged on left and right sides and bottom margin and dumper phase of the buffer layer
The thickness of contact position is 1~2cm thicker than other positions.
A kind of above-mentioned novel dump lorry back door, the buffer layer are prepared using abrasive rubber material.
A kind of above-mentioned novel dump lorry back door, the door-plate layer and support frame are all made of high manganese steel material and are prepared.
The utility model has the following advantages that and high-lighting effect compared with prior art:
The utility model has the beneficial effects that the utility model dumper is by buffer layer, door-plate layer and supporting framework at slow
Layer and dumper touching position are rushed using thickening design, it is ensured that the leakproofness between dumper when back door is closed, prevent
Cargo is unrestrained, and buffer layer can also protect door-plate layer, avoid its abrasion；Support frame is by main reinforcing rib and assistant reinforcement muscle structure
At forming triangular structure between main reinforcing rib and assistant reinforcement muscle, stability is good, practical.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is utility model diagram；
Fig. 2 is the utility model main view；
Fig. 3 is the utility model top view；
Fig. 4 is the utility model rearview.
1. buffer layer in figure, 2. door-plate layers, 3. assistant reinforcement muscle, 4. main reinforcing ribs, 5. support frames, 6. counter sinks, 7. spiral shells
Bolt.
Specific embodiment
It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model
Mode is applied to elaborate to the utility model.
[embodiment 1]
A kind of novel dump lorry back door, the self-discharging vehicle backdoor is from inside to outside successively by buffer layer 1, door-plate layer 2 and support
Frame 5 is composed, and the buffer layer 1 is equipped with counter sink 6, and position corresponding with counter sink 6 is equipped with spiral shell on the door-plate layer 2
Pit, the buffer layer 1 are fixed together with door-plate layer 2 by bolt 7, the side that the door-plate layer 2 and support frame 5 pass through welding
Formula links together, and support frame as described above 5 includes main reinforcing rib 4 and assistant reinforcement muscle 3, and the main reinforcing rib 4 is welded in matrix pattern
In the outside of door-plate layer 2, the assistant reinforcement muscle 3 is welded between main reinforcing rib 4, the main reinforcing rib 4 and assistant reinforcement muscle 3
Between form triangular structure.
Further, the thickness of the arranged on left and right sides of the buffer layer 1 and bottom margin and dumper touching position is than it
Its position thickness 1.5cm.
Further, the buffer layer 1 is prepared using abrasive rubber material.
Further, the door-plate layer 2 and support frame 5 are all made of high manganese steel material and are prepared.
Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new
The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model
It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new
In the protection scope of type.
