Abstract
The invention discloses an engineering machinery cab car door limit and protection device and relates to the field of structures of various engineering machines, such as excavators, loaders, and the like. The device comprises a front upright post, wherein one side of the front upright post is provided with a car door, and the car door comprises an outer car door plate, an inner car door plate and a connecting plate; the outer car door plate is arranged at the outer side of the inner car door plate; one end of the connecting plate is fixedly connected with one end of the inner car door plate, while the other end of the connecting plate is fixedly connected with one end of the outer car door plate; the front upright post and the opposite surface of the connecting plate are respectively and fixedly connected with a limit block; and the two limit blocks are respectively provided with at least one set of grooves and bosses which are mutually matched. In the invention, a limit and protection device made of natural rubber is increased between the car door and the cab upright post, therefore, the vibration frequency of the car door while working is reduced, and the bearing capacity (a bearing point is increased) of the cab to the car door is also improved. Through the device, the service life of a door hinge and a door lock is greatly prolonged.
Description
Technical field
The present invention relates to all kinds of engineering machinery, as the structure field of excavator, loader etc.
Background technology
At present, the engineering machinery drivers' cab is connected at 3 with car door and is connected (door hinge 2 points, door lock are a bit) because the engineering machinery construction environment is abominable, when work vibration bigger, car door itself has certain weight in addition, door lock very easily is damaged.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, a kind of engineering machinery cab door limiting and protecting device of protecting door lock is provided.
The object of the present invention is achieved like this: a kind of engineering machinery cab door limiting and protecting device; comprise front column; one side of front column is provided with car door; car door comprises door skin, inner plate of car door and junction plate; door skin is arranged on the outside of inner plate of car door; one end of junction plate is fixedlyed connected with an end of inner plate of car door; the other end of junction plate is fixedlyed connected with an end of door skin; on the opposite face of front column and junction plate, fixedly connected limited block respectively, be respectively provided to few one group of groove that cooperatively interacts and boss on two limited blocks.
The invention has the beneficial effects as follows: between car door and drivers' cab column, increase a limiting and protecting device; material is a natural rubber; so, reduced the vibration frequency of car door when work, also improved the supporting capacity (increased a bearing point) of drivers' cab simultaneously car door.By using this device, to being much improved in application life of door hinge and door lock.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 be among Fig. 1 B to enlarged drawing.
Fig. 3 be among Fig. 2 A-A to view.
The specific embodiment
As shown in Figure 1, 2, 3; be a kind of engineering machinery cab door limiting and protecting device; comprise front column 1; the rear side of front column 1 is provided with car door 7; car door 7 comprises door skin 4, inner plate of car door 5 and junction plate 6; door skin 4 is arranged on the outside of inner plate of car door 5, and an end of junction plate 6 is fixedlyed connected with the front end of inner plate of car door 5, and the other end of junction plate 6 is fixedlyed connected with the front end of door skin 4.At fixedly connected first limited block of making by natural rubber 2 of the rear side of front column 1, three groove 2-1 are set on first limited block 2, on fixedly connected second limited block, 3, the second limited blocks of making by natural rubber 3 in the front side of junction plate 6, fix three boss 3-1 that cooperatively interact with groove 2-1.
