Description of drawings

Fig. 1 is a structural schematic diagram of the first preferred embodiment of the self-rescue oil cylinder device for a truck of the present invention.

Fig. 2 is a structural schematic diagram of the second preferred embodiment of the truck self-rescue cylinder device of the present invention.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in FIG. 1 , according to the first preferred embodiment of the truck self-rescue cylinder device of the present invention, the truck self-rescue cylinder device includes: an adjustment cylinder 1 , an adjustment rod 4 and a self-rescue cylinder 5 .

The tail end of the truck chassis is arranged horizontally on the adjustment oil cylinder 1 , and the cylinder body tail of the adjustment oil cylinder 1 is hinged to the tail end of the truck chassis through the hinge shaft 2 . With this arrangement, the piston rod of the adjustment oil cylinder 1 can reciprocate along the transverse direction of the truck.

The upper end of the adjustment rod 4 is hinged to the piston rod head 11 of the adjustment oil cylinder 1 , and the lower end of the adjustment rod 4 is hinged to the cylinder tail end of the self-rescue oil cylinder 5 through the hinge shaft 52 .

In the first preferred embodiment, the adjustment rod 4 is "L" shaped, and the adjustment rod 4 includes an upper section 41 hinged with the piston rod head 11 of the adjustment cylinder 1 and a lower section 42 hinged with the self-rescue cylinder 5, The length of the upper section 41 is less than the length of the lower section 42, and the adjustment rod 4 is hinged to the tail end of the truck chassis through the hinge shaft 3 at the junction of the upper section 41 and the lower section 42. The angle between the upper section 41 and the lower section 42 is an obtuse angle.

Since the length of the lower section 42 is greater than the length of the upper section 41, the adjusting range of the position of the self-rescue oil cylinder in contact with the ground can be enlarged by adjusting the oil cylinder 1 .

Below the piston rod head 51 of the self-rescue oil cylinder 5, a support claw 6 for supporting the ground is arranged. When it is not necessary to take a self-rescue action, the movable end of the self-rescue oil cylinder 5 (that is, the end with the piston rod head) is suspended on the tail end of the truck chassis by a fixture (not shown); The free end of 5 is removed from the suspension.

As shown in FIG. 2 , according to the second preferred embodiment of the truck self-rescue cylinder device of the present invention, the truck self-rescue cylinder device includes: an adjustment cylinder 1 , an adjustment rod 4 ′ and a self-rescue cylinder 5 .

The difference between the second preferred embodiment and the first preferred embodiment lies in the shape of the adjustment rod 4 ′, and in this embodiment, the shape of the adjustment rod 4 ′ is a curved arc.

The utility model also provides a truck, which includes the truck self-rescue oil cylinder device according to the utility model.

The working process of the truck self-rescue cylinder device of the present invention will be briefly described below.

When the wheels of the truck are buried by the cargo and need to take self-rescue measures, first put down the self-rescue oil cylinder 5, control and adjust the oil cylinder 1, and manipulate the piston rod of the adjustment oil cylinder 1 to expand and contract, because the hinge shaft 2 and the hinge shaft 3 are fixed on the frame of the truck The tail end, so the self-rescue oil cylinder 5 can adjust the position in the lateral direction of the truck, so that the support claw 6 of the self-rescue oil cylinder 5 is supported on the ground. Afterwards, the self-rescue oil cylinder 5 is manipulated to make its piston rod stretch out, so that an upward and lateral thrust can be applied to the truck, so that self-rescue can be realized.

In addition, during the self-rescue operation, the further position of the self-rescue cylinder 5 along the lateral direction of the truck can also be adjusted by adjusting the operation of the oil cylinder 1, so that the self-rescue cylinder is in a suitable left and right position, so that the whole vehicle can be evenly lifted to the ideal position. state.

In the self-rescue oil cylinder device of the utility model, the adjustment oil cylinder and the adjustment rod are installed at the rear end of the chassis of the vehicle, and the self-rescue oil cylinder is installed at the lower end of the adjustment rod. With the adjustment of the adjusting rod, the position of the self-rescue oil cylinder can be changed.

The above are only preferred feasible embodiments of the present utility model, and the described embodiments are not intended to limit the scope of patent protection of the present utility model, so any equivalent structural changes made by using the specification and accompanying drawings of the present utility model, In the same way, all should be included in the protection scope of the present utility model.
