Abstract
The invention discloses a buffering device of a hydraulic hoist and belongs to the technical field of hydraulic hoists. The buffering device comprises a piston rod, a cylinder body and a piston, both the piston rod and the piston are arranged inside the cylinder body, a rod end buffering part and a rod end positioning ring which are used together are arranged at the front end of the piston rod, a rodless end buffering part and a rodless end positioning ring are arranged at the tail end of the piston rod, the piston is fixed at the tail end of the piston rod through a piston cap, and the piston rod is connected with a gate. The buffering device of the hydraulic hoist is reasonable and simple in structure and easy to maintain, and can not only realize stroke positioning but also guarantee normal gate opening and closing. Meanwhile, equipment loss is reduced, equipment maintenance charge is saved, production cost is lowered, and the buffering device is high in practicality.
Description
Technical field
The invention belongs to the hydraulic hoist technical field, be specifically related to a kind of buffer of hydraulic hoist.
Background technology
In Hydraulic and Hydro-Power Engineering, hydraulic hoist is used for the opening and closing of the big-and-middle-sized cast iron gate of control and steel gate, has the high and stable advantage of transmission efficiency.Some gate needs the stroke location of hydraulic hoist in application, to the demands for higher performance of hydraulic hoist.The piston of traditional hydraulic hoist directly contacts with fairlead, cylinder barrel bonnet, and the time one will make that for a long time piston, fairlead and cylinder barrel bonnet are injured, causes the damage of oil cylinder, makes normally starting gate of headstock gear.
Summary of the invention
Goal of the invention: at the deficiencies in the prior art, the buffer that the purpose of this invention is to provide a kind of hydraulic hoist, make its stroke location that can not only realize hydraulic hoist, and can guarantee normal gate opening/closing, reduced the loss of equipment simultaneously.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is as follows:
A kind of buffer of hydraulic hoist comprises piston rod, cylinder body and piston, and described piston rod and piston all are arranged on the inside of cylinder body; Front end at described piston rod is provided with rod end bolster and the rod end locating ring that is used, and is provided with rear end bolster and rear end locating ring at the tail end of piston rod; Described piston is fixed on the tail end of piston rod by piston and cap; Wherein, piston rod links to each other with gate.
Periphery at described piston rod is provided with fairlead.
Beneficial effect: compared with prior art, the buffer of hydraulic hoist of the present invention, rational in infrastructure simple, be easy to maintenance and maintenance, can not only realize the stroke location of hydraulic hoist, and can guarantee normal gate opening/closing, reduced the loss of equipment simultaneously, save equipment maintenance cost, reduced cost of production, had good practicability.
Description of drawings
Fig. 1 is the structural representation of the buffer of hydraulic hoist.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing.
As shown in Figure 1, the buffer of hydraulic hoist, comprise piston rod 1, fairlead 2, rod end bolster 3, cylinder body 4, piston 5, piston and cap 6, rear end bolster 7 and rear end locating ring 8, piston rod 1, fairlead 2 and piston 5 all are arranged on the inside of cylinder body 4; Piston 5 is fixed on piston rod 1 tail end by piston and cap 6, periphery at piston rod 1 is provided with fairlead 2, front end at piston rod is provided with rod end bolster 3 and the rod end locating ring that is used, and is provided with rear end bolster 7 and rear end locating ring 8 at the tail end of piston rod 1; Wherein, piston rod 1 is connected with gate.
The course of work: by the periphery at piston rod 1 fairlead 2 is set and keeps piston rod 1 not swing, stable; The rod end bolster 3 and the rod end locating ring that are used by the front end setting at piston rod, tail end at piston rod 1 is provided with rear end bolster 7 and rear end locating ring 8, in actual opening-closing process, the position, front and back end is dashed by rod end bolster 3 and rear end bolster 7, and rod end locating ring and rear end locating ring 8 are controlled the position that puts in place.
The buffer of this hydraulic hoist, rational in infrastructure simple, be easy to maintenance and maintenance, can not only realize the stroke location of hydraulic hoist, and can guarantee normal gate opening/closing, and reduced the loss of equipment simultaneously, saved equipment maintenance cost, reduce cost of production, had good practicability.
