Lifting pulley capable of being quickly clamped or released by rotary lifting spine lock, synchronously opened-closed C-shaped spring and five wheels

Abstract

The invention relates to a hoisting block for steel cables or ropes or guide rails, in particular to a hoisting block with rotating lifting ratchet lock, C-shaped spring synchronous opening and closing, and five-wheel fast hanging in or out. It is composed of lock assembly, hoisting block assembly, hoisting pulley assembly, and synchronous opening and closing clamping seat assembly; the hoisting block assembly is shaped like a 9 or designed as a U-shaped rotation of 180°; the hoisting pulley assembly The shape is like a cross with an arc-shaped groove or a polygonal groove on the upper part and the lower part; the synchronous opening and closing clamping seat assembly installed on the left or right side of the lifting block seat assembly has the same number of spare parts and the same inner and outer shapes, and can be used interchangeably. For general purpose. This product is simple and easy to manufacture and install, with strong interchangeability of spare parts, and can be standardized for mass production. When using this product, it can be quickly and automatically clamped and hung in by facing the steel cable or rope or guide rail downwards. Only need to lift the ratchet lock, lift upwards with some force, the hoisting block can quickly and automatically exit the steel cable or rope or guide rail, and it is fast, convenient and safe to use.

Description

technical field [0001] The invention relates to a hoisting block for steel cables or ropes or guide rails, in particular to a hoisting block with rotating lifting ratchet lock, C-shaped spring synchronous opening and closing, and five-wheel fast hooking in or out. Background technique [0002] At present, the commonly used hoist blocks are commonly used in the market. When using them, it is necessary to install the hoist block into the unfastened steel cables or ropes or guide rails, and then fasten the two ends of the steel cables, ropes, or guide rails before use; When another method is used, it is necessary to first disassemble the suspension block before the suspension block can be installed on the two fastened steel cables or ropes or guide rails installed. Such mode of use is very inconvenient, and even there is the phenomenon that the hoist block is stuck after jumping out of the steel cable or the rope during use, which is particularly time-consuming, delayed, and un...

Problems solved by technology

This way of use is very inconvenient, and even the hoisting block will get stuck after jumping out of the steel cable or rope during use, which is especially time-consuming, wrong, and unsafe.
