Embodiment Construction

[0019] Such as figure 1 As shown, a specific embodiment of a chain-driven synchronous hoist includes a motor 1 , and a rotatable transmission shaft 2 is connected to the motor 1 . A plurality of sprockets 3 are installed at intervals on the transmission shaft 2, so that each sprocket 3 can rotate synchronously with the transmission shaft. In this specific embodiment, two sprockets are installed on the transmission shaft, and each sprocket 3 is The lifting hoist 5 at a fixed position is driven by a chain 4 .

[0020] Such as figure 2 , 3 As shown, the specific structure of the lifting hoist in this specific embodiment, the lifting hoist 5 includes a lifting assembly 501 and a rotating shaft 502, and the rotating shaft 502 drives the lifting assembly to rotate, thereby driving heavy objects to be lifted. The upper end of the lifting assembly 501 is connected with a fixing device 6, and the fixing device 6 includes a first angle steel 601 and a second angle steel 602, and one...

Abstract

The invention discloses a chain transmission synchronous block. The chain transmission synchronous block comprises a motor, and a transmission shaft in transmission connection with the motor; multiple chain wheels are arranged on the transmission shaft at intervals; each chain wheel is in transmission with a lifting block through a chain; the lifting block comprises a lifting assembly and a rotating shaft; the upper end of the lifting assembly is connected with a fixing device; the rotating shaft is sleeved with a first brake pad, a brake ratchet and a second brake pad in sequence; the lifting assembly is provided with at least one pallet matched with the brake ratchet; the rotating shaft is sleeved with a brake disc and a transmission ratchet connected by a bolt; the tail end of the rotating shaft is tightly screwed through a flower nut to press the brake disc on the second brake pad; and the chain is wound on the transmission ratchet. The chain transmission synchronous block changes the locking chain transmission of a traditional lifting block, and adopts the chain-chain wheel transmission to achieve more stable transmission ratio; and the same one transmission shaft drives multiple lifting blocks to guarantee identical rotating speed and uniform lifting of all lifting blocks, so that all lifting blocks are synchronously and stably lifted.

Description

technical field [0001] The invention relates to the field of synchronous lifting of a hoist with multiple lifting points, in particular to a chain-driven synchronous hoist. Background technique [0002] In the process of lifting some heavy objects that require high balance, the existing lifting hoists, whether they are chain hoists or electric hoists, are used by a single lifting point, even if two or more are used, the chain hoist The lifting height will be different due to the different hand pulling force and length of each person. The electric hoist will have different lifting heights due to the different motor current or brake of each hoist. This will cause uneven weight or different heights of each lifting point, resulting in dangerous accidents such as overweight danger or unbalanced objects tilting. [0003] Therefore, there is an urgent need for a hoist that can meet the synchronous lifting of multiple lifting points to prevent uneven weight or different heights of ...
