Problems solved by technology

Only the polyurethane buffer is introduced here. The structure of the polyurethane buffer is mostly a polyurethane buffer block fixed on the metal connecting plate. The manufacturing cost of the method is relatively high. If the suit structure is fixed by welding, its rigidity index is relatively high, and it is easy to damage the mechanical main body when receiving impact.

Embodiment Construction

[0012] Such as Figure 1-2 As shown, the main structure of the present invention includes four square mounting base plates 4 with bolt mounting holes 5, the square mounting base plates 4 are fixed on the crane beam or the elevator base by bolts, and four warping plates are stamped on the square mounting base plate 4. The connecting frame 3 is connected to the square mounting base plate 4 with the polyurethane buffer column 1 connected to the connecting frame 3, and the connecting frame 3 is inserted into the polyurethane buffer column 1. In order to increase the density of the polyurethane buffer cylinder and improve its buffer effect, the polyurethane molecular weight of the polyurethane buffer cylinder is 300-6000. In order to increase the frictional force, anti-slip protrusions 2 are arranged on the top of the polyurethane buffer cylinder.

[0013] When working, the top of the polyurethane buffer cylinder 1 is the impact bearing surface. After receiving the impact force, t...

Abstract

The invention relates to a buffer which comprises a mounting bottom plate with a bolt mounting hole. The buffer is characterized in that at least three wrapped connecting skeletons are punched on the mounting bottom plate; the mounting bottom plate is connected with a polyurethane buffering column body through the connecting skeletons; and the connecting skeletons are inserted in the polyurethane buffering column body. The connecting skeletons are arranged by the punching method, therefore the rigid connection index between the mounting bottom plate and the connecting main body is decreased, and the protection function is effectively performed; as the connecting skeletons are not welded on the mounting bottom plate, the pollution to the environment is decreased in the manufacturing process. The connecting skeleton has the advantages of simple structure, material saving and decrease of manufacturing cost. The invention also has the advantages of strong anti-shock capability, stable buffering, corrosion and aging resistance, long service life, safety and reliability, and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical safety devices, in particular to a buffer. Background technique [0002] As we all know, the buffer is an important safety protection device for cranes, elevators and other machinery. The purpose is to reduce or even avoid damage to the main body of the mechanical connection through the protection of the buffer. Whether the connected machinery can operate safely. The buffers commonly used at present include various mechanisms such as spring type, rubber type, hydraulic type, polyurethane type, damping type, and liquid-pneumatic type, each with its own advantages and disadvantages. Only the polyurethane buffer is introduced here. The structure of the polyurethane buffer is mostly a polyurethane buffer block fixed on the metal connecting plate. The manufacturing cost of the method is relatively high. If the suit structure is fixed by welding, its rigidity index is relatively high, and it is eas...
