The frame is composed of support columns and connecting rods fixed between the support columns, and the top of the support columns is provided with a jacking mechanism.

The telescopic arm is composed of the first arm section, the second arm section, the third arm section and the telescopic mechanism that drives the second arm section and the third arm section to perform telescopic movement. The first arm The section is fixed on the frame.

To further improve the above technical solution, the top of the support column is a sleeve structure, the jacking mechanism is composed of a screw rod and a tray fixed on the top of the screw rod, and the screw rod is provided with a matching threaded buckle, so The lower end of the threaded rod is inserted on the top of the supporting column, and the up and down movement of the tray is adjusted by rotating the threaded button.

Further: the telescopic mechanism includes a first hydraulic cylinder and a second hydraulic cylinder, the first hydraulic cylinder includes a first cylinder body and a first piston rod, and the second hydraulic cylinder includes a second cylinder body and a second piston The first cylinder and the second cylinder are fixedly connected to form a cylinder assembly, the first piston rod and the second piston rod protrude in opposite directions, and the cylinder assembly is connected to the second arm section , the first piston rod is connected to the first arm section, and the second piston rod is connected to the third arm section.

The supporting column and the connecting rod are welded by square steel pipes.

The length of the first boom section is 3000mm, and the length of the second boom section and the third boom section are both 1000mm.

The utility model fixes the whole crane between the upper and lower floors through the jacking mechanism at the top of the supporting column. Extend, lift heavy objects.

Compared with the prior art, the utility model has the beneficial effects of:

The utility model forms a reasonable force-bearing form through its own structure, and the downward force provided by the top plate offsets the moment when lifting. Compared with the traditional counterweight lifting machinery, it is more convenient, economical and safe, and meets the requirements of larger load capacity.
