Abstract
The utility model discloses a high pressure hydraulic jack for vehicle, which consists of a support, a high pressure oil pump, a hydraulic jack and a high pressure oil pipe connecting the high pressure oil pump and the hydraulic jack. The high pressure oil pump comprises a high pressure oil chamber, a cam shaft, a low pressure oil pump, a plunger and a telescopic lifting control handle. The hydraulic jack comprises a hydraulic cylinder and two expansion rods in the hydraulic cylinder, wherein, the hydraulic cylinder is equipped with a high pressure oil inlet, an oil return port, a check valve and a decompression valve; the high pressure oil inlet is communicated with a high pressure oil outlet on the telescopic lifting control handle through the high pressure oil pipe; the oil return port on the hydraulic cylinder is communicated with the oil return port on the telescopic lifting control handle through an oil return pipe; and the decompression valve is equipped with a control rod. The utility model has the following advantages: 1. because the high pressure oil pump is used for providing power for the hydraulic jack, the utility model has large lifting tonnage and fast lifting speed, saves time and effort, and is ideal for lifting heavy vehicles; 2. a certain space is left between the operator and the hydraulic jack, in case the trouble occurs in the hydraulic jack, the operator does not be injured, so the safety performance is increased greatly.
Description
Technical field
The utility model relates to a kind of vehicle high-pressure and hydraulic jack.
Background technology
Traditional jack of wearing with car, lifting power is less, can only adapt to the light vehicle changing of tire of weight, heavy-duty vehicle is used very inconvenient, because this class jack is by manual operation, so manpower and the time consumed when changing tire are all a lot, the speed of jack-up weight is also very slow and must work under car, bring many inconvenience to the operator, will work the mischief to personal safety in case break down.
The utility model content
The purpose of this utility model provides the vehicle high-pressure and hydraulic jack that a kind of lifting power is big, hoisting speed is fast, safe and reliable.
The technical solution of the utility model is: a kind of vehicle high-pressure and hydraulic jack, form by support, high-pressure oil pump, hydraulic jack with both bonded assembly high pressure fuel pipes; High-pressure oil pump is contained on the support, comprises high-voltage oil cavity, camshaft, Low Fuel Pump, plunger and telescoping lifting bar handle; Telescoping lifting bar handle is made up of hollow pull rod and its outer sleeve pipe, on sleeve pipe, be provided with return opening, high pressure oil outlet and low pressure oil oil inlet, be respectively equipped with on the hollow pull rod with sleeve pipe on return opening, high pressure oil outlet, low pressure oil oil inlet and the corresponding connected entrance of high-voltage oil cavity connected entrance, the low pressure oil oil inlet is communicated with Low Fuel Pump; Hydraulic jack comprises two section telescopic bars of hydraulic cylinder and Qi Nei, is provided with high pressure oil oil inlet, return opening, boiler check valve and blowdown valve on hydraulic cylinder; The high pressure oil oil inlet is communicated with high pressure oil outlet on the telescoping lifting bar handle by high pressure fuel pipe, and return opening is communicated with return opening on the telescoping lifting bar handle by oil return pipe, and joystick is housed on the blowdown valve.
Roller is housed on support.
The utility model has following advantage:
1, owing to adopt high-pressure oil pump power to be provided for the hydraulic pressure jack, so the lifting tonnage is big, it is fast, time saving and energy saving to be fit to very much heavy-duty vehicle use and lifting speed.
2, operator and hydraulic jack have certain distance, and in a single day hydraulic jack breaks down and also can not damage to the operator, and safety performance is improved greatly.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
The utility model structure is as shown in Figure 1: form by support 1, high-pressure oil pump, hydraulic jack with both bonded assembly high pressure fuel pipes; High-pressure oil pump is contained on the support 1, comprises high-voltage oil cavity 4, camshaft 3, Low Fuel Pump 10, plunger 6 and telescoping lifting bar handle 5; Telescoping lifting bar handle is made up of hollow pull rod 11 and its outer sleeve pipe 12, on sleeve pipe, be provided with return opening 13, high pressure oil outlet 14 and low pressure oil oil inlet 15, be respectively equipped with on the hollow pull rod with sleeve pipe on return opening, high pressure oil outlet and the corresponding connected entrance of low pressure oil oil inlet, low pressure oil oil inlet 15 is communicated with Low Fuel Pump 10; Hydraulic jack comprises two section telescopic bars 19,20 of hydraulic cylinder 18 and Qi Nei, is provided with high pressure oil oil inlet 19, return opening 20, boiler check valve 21 and blowdown valve 22 on hydraulic cylinder 18; High pressure oil oil inlet 19 is communicated with high pressure oil outlet 14 on the telescoping lifting bar handle by high pressure fuel pipe 24, return opening 20 is communicated with return opening 13 on the telescoping lifting bar handle by oil return pipe 25, joystick 26 is housed on the blowdown valve 22, controls the keying of blowdown valve 22 by swivel lever 26.For the ease of moving of this high-pressure and hydraulic jack roller 28 is housed on support 1.
The working process of high pressure pump:
By Low Fuel Pump 10 hydraulic oil is supplied with in the high-voltage oil cavity 4, high pressure oil is exported by high pressure fuel pipe 24 by high pressure pump plunger 6.
Working process of the present utility model:
The hollow pull rod 11 of telescoping lifting bar handle is pushed in, connect Low Fuel Pump and high-pressure oil pump oil pipe to high-voltage oil cavity 4 fuel feeding and produce high pressure oil, the hydraulic cylinder of the high pressure oil outlet pipe being connected to hydraulic jack 18 supplies high pressure oil simultaneously, promotes hydraulic jack and carries out lifting work.The hollow pull rod 11 of telescoping lifting bar handle is pulled out, Low Fuel Pump and high-pressure oil pump oil pipe are disconnected no longer fuel feeding, simultaneously the oil return pipe on the hydraulic jack hydraulic cylinder 25 is connected, hydraulic oil is sucked back in the high-pressure oil pump, open blowdown valve 22 on the hydraulic jack hydraulic cylinder by joystick 26, two section telescopic bars 19,20 of hydraulic jack are fallen back in the hydraulic cylinder 18.
