Embodiment Construction

[0022] With reference to the accompanying drawings, the labor-saving device for the no-load action test of a chain hoist of the present invention includes a base 12, a stand 3 and a control box 5, and the stand 3 is sequentially provided with a first cantilever beam 1 and a second cantilever beam from top to bottom. The second cantilever beam 6, the third cantilever beam 9 and the fourth cantilever beam 10, the four cantilever beams are placed in the same vertical plane.

[0023] An electric hoist cover 2 is fixed below the first cantilever beam 1 , and an electric hoist is arranged inside the electric hoist cover 2 . Electric hoist cover bottom surface has a square mouth 14, and the suspension hook 13 of electric hoist can pass through from square mouth, is connected with the hook of manual hoist.

[0024] Both sides of the second cantilever beam 6 are provided with a pair of first guide mechanisms 7, the first guide mechanism 7 includes a pair of polished rods, and each poli...

Abstract

The invention discloses a labor-saving device for carrying out a hand chain hoist no-load action test, which includes a base, an erect support and a controller, wherein a first cantilever, a second cantilever, a third cantilever and a fourth cantilever are sequentially arranged on the erect support from top to bottom and placed in the same vertical plane. The device is characterized in that an electric hoist is arranged below the first cantilever; a pair of first guide mechanisms is arranged on the two sides of the second cantilever; a power mechanism is arranged above the third cantilever; and a pair of second guide mechanisms is arranged on the two sides of the fourth cantilever. The labor-saving device provided by the invention has the following characteristics: firstly, as a pendant point of the hand chain hoist is arranged on a lifting hook of the electric hoist and the lifting hook is vertically adjustable, the hand chain hoist is convenient to take away and place on; secondly, a chain wheel or a friction wheel replaces a driving wheel according to the required friction force of the chain of the hand chain hoist; and thirdly, the structure is simpler, the manufacturing cost is lower, the machining consistency is excellent, and the labor-saving device is suitable for mass production.

Description

technical field [0001] The invention relates to a test device, in particular to a no-load action test device for a hand-chain hoist, in particular to a labor-saving device for carrying out the no-load action test of a hand-chain hoist. Specifically, with the help of this labor-saving device, instead of manually pulling the hand chain of the chain hoist repeatedly, it is tested whether the no-load action test of the chain hoist still meets the requirements. Background technique [0002] Chain block is a kind of manual lifting machinery that is easy to use and easy to carry. It is mainly composed of lifting chain, manual chain, brake and hook, and is suitable for lifting goods and hoisting equipment. [0003] In order to ensure the normal operation of the chain hoist and reliable braking, a no-load action test should be carried out, that is, the chain hoist is suspended on the bracket, and the hand chain is pulled back and forth manually under the no-load state to make the low...
