Problems solved by technology

[0003] The claw device is one of the important parts in driving, but the existing claw device still has certain deficiencies. When the existing claw device is grabbing objects, it is often because of the poor positioning of the claw that the grasped Items are detached from the hanging claws, which may cause casualties if you are not careful

Embodiment Construction

[0013] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0014] Such as figure 1 and figure 2 The crane claw device for driving shown includes four claw hooks 1 arranged opposite to each other. The top, middle and tail of each claw hook 1 are provided with pin holes 2. The pin hole 2 is provided with a pin 4 with a fixed sleeve 3 in the middle, and two groups of pin holes 2 at the corresponding positions in the middle of the four claw hooks 1 are provided with two pins 4 with a fixed sleeve 3 in the middle, and the four claw hooks Two sets of pin holes 2 at the corresponding positions of the tail are provided with two pins 4 with fixed sleeves 3 sleeved in the middle, and the tail ends of the four claw hooks 1 ar...

Abstract

The invention relates to the technical field of a hoisting claw device and in particular relates to a hoisting claw device for a travelling crane. The hoisting claw device for the travelling crane comprises four claw hooks which are paired in a corresponding manner, wherein the top part, the middle part and the tail part of each claw hook are provided with pin holes, pins of which the middle parts are sheathed with fixing sleeves are arranged in four pin holes at the top parts of the four claw hooks correspondingly, two pins of which the middle parts are sheathed with fixing sleeves are arranged in two groups of pin holes in the middle parts of the four claw hooks correspondingly, two pins of which the middle parts are sheathed with fixing sleeves are arranged in the two groups of pin holes at the tail parts of the four claw hooks correspondingly, and claws for holding an article are arranged at the tail ends of the four claw hooks. According to the hoisting claw device for the travelling crane, the claws are arranged at the grabbing parts of the claw hooks, and therefore, the hoisting claw has a good locating effect, and the article cannot be separated from the hoisting claw easily.

Description

technical field [0001] The invention relates to the technical field of claw devices, in particular to a claw device for driving. Background technique [0002] The driving is basically the same as the cranes we call now, and can be roughly divided into two categories: one is centralized drive, that is, a motor is used to drive the long drive shaft to drive the active wheels on both sides; the other is separate drive, that is, the active wheels on both sides Each is driven by an electric motor. Medium and small bridge cranes mostly use the "three-in-one" drive mode that combines brakes, reducers and motors. Ordinary bridge cranes with large lifting capacity are easy to install and adjust. The drive device often uses a universal coupling. . [0003] The claw device is one of the important parts in driving, but the existing claw device still has certain deficiencies. When the existing claw device is grabbing items, it is often because of the poor positioning of the claw that ...
