Embodiment Construction

[0032] The following is attached Figure 1-4 The application is described in further detail.

[0033] The embodiment of the present application discloses a high-stability and safe electric hoist.

[0034] refer to figure 1 , figure 2The high-stability safety electric hoist of this embodiment includes an electric hoist body 1, a lifting motor 11 and a hook 12 for hanging heavy objects. , the output shaft of the lifting motor 11 is arranged horizontally and extends into the electric hoist body 1 , and the output shaft of the lifting motor 11 is rotatably connected in the electric hoist body 1 . Two lifting cables 13 are coiled on the output shaft of the lifting motor 11. The two lifting cables 13 are located at the two ends of the output shaft of the lifting motor 11 respectively. 1 stretches out and is jointly fixedly connected on the suspension hook 12. In order to limit the position of the two lifting cables 13 on the output shaft of the lifting motor 11, two sets of li...

Abstract

The invention relates to a high-stability safety type electric hoist which comprises an electric hoist body, wherein two lifting steel cables connected with a lifting motor are arranged below the electric hoist body. The high-stability safety type electric hoist further comprises an auxiliary stabilizing device, wherein the auxiliary stabilizing device comprises two first driving pieces and two abutting rods, wherein a mounting base is arranged below the electric hoist body; the two lifting steel cables penetrate through and are movably connected onto the mounting base; one end of each abutting rod is slidably connected onto the mounting base; the other end of each abutting rod is located below the mounting base and faces the corresponding lifting steel cable; the end, away from the mounting base, of each abutting rod is located between the two lifting steel cables; and when the lifting steel cables shake toward one side, the first driving pieces drive the corresponding abutting rods to move in the direction away from the shaking sides of the lifting steel cables and abut against the lifting steel cables. The lifting steel cables can be prevented from continuously shaking towards the side, so that the shaking amplitude of the lifting steel cables can be reduced, and a heavy object on a lifting hook is not prone to falling off from the lifting hook.

Description

technical field [0001] The present application relates to the field of electric hoists, in particular to a high-stability and safe electric hoist. Background technique [0002] Electric hoist is a kind of special lifting equipment, which is installed on the crane and gantry crane. The electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage, docks and other places. [0003] The electric hoist has a compact structure, and the electric hoist whose motor axis is perpendicular to the drum axis adopts a worm gear transmission. Its disadvantages are: large length, large width, bulky structure, low mechanical efficiency, and difficult processing. The hydraulic system is double controlled, and the overflow regulating valve and the magnetic contact pressure gauge can control the pressure precisely. The electrical control department adopts low-voltage control, which increases the...
