Technical Field

[0001] The present invention relates to the technical field of forklifts, and in particular to a rescue forklift. Background Art

[0002] A traditional rescue forklift includes a frame, an overhead guard, a lifting mast, a counterweight and a mounting frame. The overhead guard is welded to the top of the frame, the lifting mast and the counterweight are welded to both ends of the frame respectively, the mounting frame is installed on the lifting mast and is driven up and down by the lifting mast, and a fork is connected to the side of the mounting frame away from the lifting mast.

[0003] When implementing rescue operations, the traditional rescue forklift cannot be turned over as needed and cannot fork up the fallen objects or obstacles because the objects are too large and have irregular shapes. Sometimes, due to space constraints, the forklift does not have enough space to move the obstacles to the designated location, so the obstacles need to be turned over to the side. However, the existing traditional rescue forklifts cannot meet this demand. Therefore, there is an urgent need for a rescue forklift that can perform turning or lifting operations. Summary of the invention

[0004] In order to solve the problem that large obstacles are difficult to flip in rescue scenarios, the present invention provides a rescue forklift, which can achieve operations such as supporting and flipping obstacles through multi-degree-of-freedom adjustment of the fork, and ultimately achieve rescue of the target.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a rescue forklift, including: a frame body, an overhead guard, a hydraulic operating mechanism, a left fork, and a right fork. The overhead guard is installed above the cab of the frame body to protect the cab. The front end of the frame body is connected to the left fork and the right fork through the hydraulic operating mechanism, and the left fork and the right fork are controlled by controlling the hydraulic operating mechanism to carry and flip obstacles.

[0006] Furthermore, the left fork and the right fork are both L-shaped forks.

[0007] Furthermore, the hydraulic operating mechanism includes: a left adjusting cylinder, a right adjusting cylinder, a telescopic cylinder, a luffing cylinder, and a connecting pin shaft. One end of the left adjusting cylinder, the right adjusting cylinder, the telescopic cylinder, and the luffing cylinder are hinged on the frame body, the luffing cylinder is located below the telescopic cylinder, the other end of the luffing cylinder is hinged to the middle of the telescopic cylinder, both ends of the connecting pin shaft are respectively connected to the left fork and the right fork, the other end of the telescopic cylinder is hinged to the connecting pin shaft, the other end of the left adjusting cylinder is hinged to the left fork, and the other end of the right adjusting cylinder is hinged to the right fork, so as to realize independent adjustment of the fork angle.

[0008] Furthermore, the other end of the left adjusting cylinder is hinged to the upper end of the left fork.

[0009] Furthermore, the other end of the right adjusting cylinder is hinged to the upper end of the right fork.

[0010] Furthermore, both ends of the connecting pin are respectively hinged at the roots of the left fork and the right fork, that is, the bending part of the L-shaped fork.

[0011] Furthermore, it also includes: a left adjusting cylinder support, the left adjusting cylinder support is fixed on the frame body, and one end of the left adjusting cylinder is hinged on the left adjusting cylinder support.

[0012] Furthermore, it also includes: a right adjusting cylinder support, the right adjusting cylinder support is fixed on the frame body, and one end of the right adjusting cylinder is hinged on the right adjusting cylinder support.

[0013] Furthermore, it also includes: a telescopic cylinder support, the telescopic cylinder support is fixed on the frame body, and one end of the telescopic cylinder is hinged on the telescopic cylinder support.

[0014] Furthermore, it also includes: a luffing cylinder support, the luffing cylinder support is fixed on the frame body, and one end of the luffing cylinder is hinged on the luffing cylinder support.

[0015] The beneficial effects of the present invention are as follows: the left fork and the right fork are controlled respectively by the left adjusting cylinder and the right adjusting cylinder, so that they are controlled separately, and the left fork and the right fork are connected by a connecting pin shaft, so that they are linked and have high stability. At the same time, the connecting pin shaft is also controlled by the telescopic cylinder and the amplitude-changing cylinder, so that the left fork and the right fork can be further controlled to achieve multi-degree-of-freedom adjustment. The left fork and the right fork can be adjusted according to actual needs on site to better insert large obstacles, which is more flexible and can be better applied to rescue situations. It also solves the flipping problem of large obstacles that are not easy to move in rescue scenes, thereby improving rescue efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
