Rotary lifting ratchet locking and synchronous opening and closing five-wheeled hoisting tackle capable of achieving rapid hanging or disengaging

Abstract

The invention relates to a hoisting tackle used for a steel cable or a rope or a guide rail, in particular to a rotary lifting ratchet locking and synchronous opening and closing five-wheeled hoisting tackle capable of achieving rapid hanging or disengaging. The rotary lifting ratchet locking and synchronous opening and closing five-wheeled hoisting tackle capable of achieving rapid hanging or disengaging is composed of a rotary lifting ratchet lock assembly, a hoisting tackle base assembly, a hoisting pulley assembly and synchronous opening and closing clamping base assemblies. The hoisting tackle base assembly is approximately in the shape of the Arabic numeral 9 or is designed to be in the shape of a U which is rotated by 180 degrees. The hoisting pulley assembly is approximately in a cross shape with two arc-shaped grooves or polygonal grooves formed in the upper portion and the lower portion correspondingly. The number, internal shapes and external shapes of spare and accessory parts of the synchronous opening and closing clamping base assembly installed on the left side of the hoisting tackle base assembly are the same as those of spare and accessory parts of the synchronous opening and closing clamping base assembly installed on the right side of the hoisting tackle base assembly, and the spare and accessory parts of the synchronous opening and closing clamping base assembly installed on the left side of the hoisting tackle base assembly and the spare and accessory parts of the synchronous opening and closing clamping base assembly installed on the right side of the hoisting tackle base assembly can be interchanged and universal. The hoisting tackle is easy to manufacture and install, the interchangeability of the spare and accessory parts is high, and standard volume production can be achieved; by the adoption of the hoisting tackle, the steel cable or the rope or the guide rail can be hung in the hoisting tackle rapidly and automatically only by approximately lowering the hoisting tackle in the direction facing the steel cable or the rope or the guide rail; when rapid disengagement is needed, the steel cable or the rope or the pulley can be disengaged from the hoisting tackle rapidly and automatically only by lifting the ratchet lock upwards with certain lifting force; and using is rapid, convenient and safe.

Description

technical field [0001] The invention relates to a hoist block for steel cables or ropes or guide rails, in particular to "a hoist block with rotating lifting ratchet lock, synchronous opening and closing, and five-wheel fast hanging 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 unsafe.
