Abstract
The utility model relates to a shielded cover for oil cylinder, particularly suitable for hydraulic cylinders of different constructive machineries. The utility model comprises a fixed shield of the cylinder tube and a servo shield of the cylinder pole. One side of the fixed shield is fixed on the cylinder tube by grip, and the other side is fixed on the bottom pin of the cylinder. One end of the servo shield is connected with the fixed shield, and the other end is connected with the top pin of the cylinder. The utility model has the advantages of simple structure, low cost, good protection of the cylinder and the pole from being damaged, lower maintaining cost and higher work efficiency.
Description
Affiliated field:
The utility model relates to a kind of oil cylinder protective cover, is specially adapted to the protective cover on the various engineering mechanical hydraulic oil cylinders.
Background technology:
At present; the hydraulic jack of excavator, bulldozer, loader is when operation; without any protection, the driver generally cannot see its duty when cylinder rod stretched out outside the oil cylinder pipe, full operation by rule of thumb; because the restriction of operating environment; cylinder rod very easily damages, and the lighter's oil sealing damages, and needs to change oil sealing; mend plating coating, weight person then changes hydraulic cylinder assembly.
Summary of the invention:
The purpose of this utility model is in order to overcome deficiency of the prior art, and provides a kind of simple in structure, and protection oil cylinder, cylinder rod are not impaired, reduce maintenance cost, the oil cylinder protective cover of increasing work efficiency.
The purpose of this utility model is achieved in that it comprises oil cylinder pipe fixed cover and cylinder rod servo-actuated cover, described fixed cover one end is fixed on the oil cylinder pipe by clamp, the other end is sold at the bottom of being fixed on oil cylinder, and servo-actuated cover one end links to each other with fixed cover, and the other end links to each other with the oil cylinder ejector pin.
Described clamp is made of movable clip and fixation clamp two parts, and the fixation clamp two ends are welded on the fixed cover, and movable clip is connected by set bolt with fixation clamp.
The utlity model has simple in structurely, cost of manufacture is cheap, and protection oil cylinder, cylinder rod are not impaired, reduce maintenance cost, advantage such as increase work efficiency.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view Amplified image of this Fig. 1.
The specific embodiment:
Be described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, it comprises oil cylinder pipe 7 fixed covers 5 and cylinder rod 3 servo-actuated covers 2, described fixed cover 5 one ends are fixed on the oil cylinder pipe 7 by clamp 6, the other end is sold on 8 at the bottom of being fixed on oil cylinder, fixed cover 5 is connected with oil cylinder pipe 7 parallel longitudinals, both vertical distances equate that fixed cover 5 promptly plays the effect of protection oil cylinder, plays the fixedly effect of servo-actuated cover 2 again; Servo-actuated cover 2 one ends are inserted in the fixed cover 5; flexibly connect with fixed cover 5 plug-in type that is in line; the other end links to each other with oil cylinder ejector pin I; cylinder rod 3 is in oil cylinder pipe 7 time; servo-actuated cover 2 also contracts in fixed cover 5, and when cylinder rod 3 stretched out, servo-actuated cover 2 also freely stretched out; promptly do not influence the oil cylinder operate as normal, can play a protective role again.
As shown in Figure 2, described clamp 6 is made of movable clip 9 and fixation clamp 10 two parts, and fixation clamp 10 two ends are welded on the fixed cover 5, and movable clip 9 is connected by set bolt 4 with fixation clamp 10.
