Abstract
The utility model relates to an oil drain device for overhaul of an oil cylinder of a hydraulic hoist. A first flange and a second flange are respectively arranged on the front part and the back part of a body of the oil drain device, and an end cover flange is arranged on the back end of the body of the oil drain device; a movable rod penetrates through the end cover flange and is positioned on a center line of the body of the oil drain device, a sleeve head is arranged on one end of the movable rod, and a handle is arranged on the other end of the movable rod; and an oil drain pipe provided with an oil drain ball valve is arranged on a lower wall of the body of the oil drain device. The oil drain device for the overhaul of the oil cylinder of the hydraulic hoist has the advantages of convenience in installation, simplicity in operation, good safety performance, low labor intensity of people, high work efficiency and good environmental friendliness.
Description
Technical field
The utility model belongs to oil cylinder of hydraulic headstock gear maintenance oil extraction device.
Background technique
During the hydraulic hoist overhaul, check chock plug, piston seal, the sealing of cylinder body cavity of resorption, piston rod, the inboard wall of cylinder block of oil hydraulic cylinder, just the hydraulic oil in the oil hydraulic cylinder must be drained that clean rear is capable of hoisting to be gone out piston body and check processing.The oil drainage hole of oil hydraulic cylinder is arranged on oil hydraulic cylinder lower end cap place, adopts plug to carry out shutoff, only plug need be unscrewed during oil extraction and lay down, and gets final product oil extraction.The usual manner that starts oil extraction is to turn on plug earlier, and the oil extraction device that will have ball valve and straight-through tube is screwed in the oil drainage hole fast, connects oil drain hose after the oil extraction device is tightened and hydraulic oil can be drained into the maintenance oil tank; This oil extraction device simple in structure, operation is light, but has following defective in the oil drainage hole docking operation of oil extraction device and oil hydraulic cylinder:
1, the staff is difficult to finish rapidly with the oil drainage hole screw thread of oil hydraulic cylinder and docks under band oil pressure situation, during butt joint not only draining splash, staff's operational condition is abominable, and runs oily situation and be difficult to avoid, not only cause economic loss to enterprise, also cause environmental pollution simultaneously.
2, inefficiency needs more than the cooperation personnel four-player;
3, the band oil pressure connects by force, and operational condition is abominable, easily causes the oil extraction staff to produce the psychology of fear, brings uncertain potential safety hazard to the staff.
The model utility content
The oil cylinder of hydraulic headstock gear maintenance oil extraction device that the technical problems to be solved in the utility model provides a kind of easy for installation, simple to operate, performance safety, reduces labor intensity, increases work efficiency.
The utility model solves the problems of the technologies described above with following technological scheme:
At the front and rear of oil extraction device main body, first flange and second flange are arranged respectively, there is the end cap flange rear end; Motion bar passes the end cap flange and locatees at oil extraction device main center line, and the one end has collet head, and the other end has handgrip; An oil exit pipe that the oil extraction ball valve is housed is arranged on the following wall of oil extraction device main body.
The front end of oil extraction device main body is cambered surface, and the radian of its radian and cylinder wall is complementary.
Between the ear end face of the oil extraction device inboard in the hole that crosses of motion bar and end cap flange and end cap flange and oil extraction device main body, first seal ring and second seal ring are arranged respectively.
Use oil cylinder of hydraulic headstock gear of the present utility model maintenance oil extraction device, easy for installation, simple to operate, Safety performance is good, and also labor strength is low, high working efficiency, and environmental protection is good.
Description of drawings
Fig. 1 is the structural representation of the utility model oil cylinder of hydraulic headstock gear maintenance oil extraction device.
Fig. 2 is the plan view after the oil extraction device main body complete section.
Among the figure: the 1-second flange 2-end cap flange 3-first flange 4. oil extraction device main body 5.-first seal ring 6-second seal ring 7-motion bar 8-collet head 9-oil exit pipe 10-oil extraction ball valve 11-handgrip
Embodiment
As shown in Figure 1, on the outer surface of the front and rear of oil extraction device main body, first flange 3 and second flange 1 are arranged respectively, there is end cap flange 2 rear end, and 4 screws are arranged on each flange; Motion bar 7 passes end cap flange 2 and locatees at oil extraction device main center line, and the one end has collet head 8, and the other end has handgrip 11; An oil exit pipe 9 that oil extraction ball valve 10 is housed is arranged on the following wall of oil extraction device main body.
The front end of oil extraction device main body is cambered surface, and the radian of its radian and cylinder wall is complementary.
Between the ear end face of the oil extraction device inboard in the hole that crosses of motion bar 7 and end cap flange 2 and end cap flange 2 and oil extraction device main body, first seal ring 5 and second seal ring 6 are arranged respectively
When the hydraulic hoist overhaul, earlier cylinder hydraulic oil to be discharged.At first centered by the oil drainage hole that is positioned at the cylinder body cavity of resorption, with the distance identical with oil extraction device flange diameter, around oil drainage hole, weld 4 full tooth bolts equidistantly.Cylinder surface around oil drainage hole is adorned a leak-stopping rubber; Unscrew 1～2 pitch of oil drainage hole plug on the oil cylinder with instrument, leak-stopping rubber is pressed at the oil drainage hole place that again the cambered surface end of oil extraction device main body is installed to cylinder body, cambered surface and leak-stopping rubber and cylinder surface are adjacent to, and first flange is inserted in the oil drainage hole full tooth bolt all around, and it is fixing to tight a bolt.
After oil extraction device main body installs, select the collet head that matches with plug wire head size, to motion bar 7 successively pack into first seal ring 5 and collet head 8, after motion bar 7 is in place, that second seal ring 6 and end cap flange 2 is in place, fastening.Rotating motion bars 7 by handgrip 11 can open the oil drainage hole plug wire, through oil exit pipe 9, oil extraction ball valve 10 and oil drain hose with the dispatch of cylinder body inner product oil to overhauling oil tank.
Claimant's Datang rock beach hydroelectric power Co., Ltd uses oil extraction device of the present invention from beginning in 2009 01 month when the #3 hydraulic hoist overhauls, its effect is as follows:
1, reduces the oily rate 99% of race, increase work efficiency 80%;
2, easy for installation, simple to operate, usage safety performance is good, only need 2 staff just can finish oil extraction device and oil extraction work (wherein one being called the manual arc welder) be installed;
3, keep the cylinder body original appearance;
4, improve operating personnel's personal safety coefficient.
