Embodiment Construction

[0012] The technical solution adopted by the present invention is: it is composed of a suspension block assembly, a suspension pulley assembly, and a synchronous opening and closing clamping seat assembly:

[0013] see figure 1 . figure 2 .The shape of the hoist block assembly is like a 9 or designed as a U-shape rotated 180°. The hoist block assembly consists of an upper replaceable suspension (1), a hoist block (2), and a lower replaceable suspension (10). , Lower adjustment tightening screw (11), lower column spring (12), lower positioning column (13), upper adjustment tightening screw (15), upper column spring (19), upper positioning column (21) composition. The upper replaceable suspension (1) is fastened with screws or formed on the upper part of the suspension block (2) by casting or machining; The column (13) is assembled in the both sides of the lower part of the suspension block (2) in order, and the lower positioning column (13) can elastically slide up and down...

Abstract

The invention relates to a crane tackle for a steel cable or a rope or a guide rail, in particular to a plunger spring, synchronous opening and closing and five-wheel rapid hanging-in or quitting crane tackle. The crane tackle is composed of a crane tackle base assembly, a crane pulley assembly and synchronous opening and closing clamping base assemblies. The shape of the crane tackle base assembly is like the Arabic number nine or is designed into a shape like a U shape rotated by 180 degrees. The shape of the crane pulley assembly is like a cross shape with an arc groove or a polygon groove in each of the upper portion and the lower portion. Accessories of the clamping base assemblies arranged on the left side or the right side of the crane tackle base assembly are the same in number, inner shape and outer shape, can be interchanged and can be in common use. The crane tackle is easy to manufacture and install, the accessory interchangeability is high, and standard batched production can be achieved. When the crane tackle is used, rapid and automatic clamping and hanging-in can be achieved only through downward force exerting approximately towards the steel cable or the rope or the guide rail, the crane tackle can rapidly and automatically quit the steel cable or the rope or the guide rail through upward forceful lifting, and using is rapid, convenient and safe.

Description

technical field [0001] The invention relates to a suspension block for steel cables or ropes or guide rails, in particular to a "column spring, synchronous opening and closing, five-wheel fast hanging in or out suspension block". Background technique [0002] At present, the common and commonly used crane blocks on the market need to be installed on the steel cables or ropes that have not been fastened before use, and then fasten the two ends of the steel cables or ropes before use; another method When in use, it is necessary to unload the side plate of the suspension block before the suspension block can be installed on the steel cables or ropes fastened at both ends. Such a mode of use is very inconvenient, and even the phenomenon that the hoisting block jumps out of the steel cable or the rope gets stuck after it is used, which is particularly time-consuming, delayed, and unsafe. Contents of the invention [0003] The purpose of the present invention is to disclose a k...
