Abstract

The invention provides a chain block, belongs to the technical field of machinery and solves the technical problems such as poor stability and reliability of the existing chain block. The chain block comprises a lifting chain and a hand-pulling chain, which are respectively meshed with a lifting chain wheel and a hand-pulling chain wheel; a right wall board and a left wall board are connected with the lifting chain wheel by bearings; the lifting chain wheel is fixedly connected with a long shaft; the hand-pulling chain wheel is sleeved on the long shaft and can rotate relative to the long shaft; at least three support rods I are connected between a left shield cover and a right shield cover; the support rods I penetrate through the left wall board and the right wall board and are provided with a positioning shaft shoulder I; two side faces of the positioning shaft shoulder I are respectively abutted against the inside faces of the left wall board and the right wall board; at least two support rods II are further arranged between the left and right wall boards and are provided with a positioning shaft shoulder II; two side faces of the positioning shaft shoulder II are respectively abutted against the inside faces of the left and right wall boards. The chain block has the advantages of better stability and reliability.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a chain block. Background technique [0002] Chain hoist, also known as fairy gourd, is a kind of manual lifting machine that is easy to use and easy to carry. It is also called "chain hoist" or "inverted chain". It is suitable for short-distance hoisting of small equipment and goods, and the lifting capacity generally does not exceed 100T. The hand chain hoist rotates by pulling the hand chain and the hand chain wheel, and presses the friction disc ratchet and the brake seat to rotate together. The long axis of the teeth is convenient. Rotating plate gear, toothed stub shaft and splined hole gear. Like this, the hoisting sprocket wheel that is installed on the spline hole gear just drives the hoisting chain, thereby lifts heavy object smoothly. The ratchet friction plate type one-way brake is adopted, which can automatically brake under load. The pawl meshes with the ratchet un...
