Embodiment Construction

[0015] The following will be further described in conjunction with the accompanying drawings, not to limit the scope of the present invention.

[0016] see figure 1 and figure 2 Shown, the present invention comprises trailer 2 that ten cylinders are housed, ground hydraulic jacking device 1, substation hydraulic oil tank 9, hydraulic pump 10, gas filling machine 6, is fixed with ten independent cylinders on the traveling mechanism of trailer 2 The gas cylinders 3, the front end of each gas cylinder 3 is an air inlet and outlet circuit, and its rear end is an oil inlet and outlet circuit, all of which are pneumatic valve control switches. All the inlet and outlet gas lines converge to an air tube socket 13, and the oil inlet and outlet channels of every five gas cylinders converge to an oil tube socket 14. Both the gas tube socket 13 and the oil tube socket 14 are equipped with quick connectors, which are connected through a high-pressure soft The pipes are respectively conn...

Abstract

The invention relates to a ground jacking-type large-capacity hydraulic substation. According to the invention, 10 gas cylinder large-capacity hydraulic substation trailers and substation ground hydraulic jacking devices are cooperatively used; therefore the jacking height and the weight of a trailer walking mechanism are reduced effectively; the requirement on large demanded quantity of the natural gas is met; and the safety and the reliability of gas supply devices is guaranteed. The ground jacking-type large-capacity hydraulic substation is characterized in that a ground jacking device is integrated with a jacking system and a hydraulic pump into a whole; and the ground jacking-type large-capacity hydraulic substation is equipped with an automatic control system device. The ground jacking-type large-capacity hydraulic substation has the advantages of compact structure, small occupied area, flexibility and convenience for operating, safety, stability and reliability.

Description

technical field [0001] The invention belongs to the field of bottle-type high-pressure container transport vehicles, and in particular relates to a ground-lifting large-capacity hydraulic substation. Background technique [0002] At present, domestic and foreign natural gas hydraulic sub-stations generally use hydraulic sub-station trailers with 8 gas cylinders. When the hydraulic sub-station trailer is supplied with gas, it is necessary to raise the hydraulic support frame installed in the front of the trailer to properly raise the front, which is about 10. °, so that the gas can be unloaded to the maximum extent, and it is beneficial to oil return. Due to the large lifting angle and the long stroke of the hydraulic cylinder, the frame structure can only be used to fix the 8 cylinder hydraulic substation trailers for safety reasons. With the widespread application of natural gas vehicles, the demand for natural gas in the market has greatly increased. It has become an inev...
