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 with 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 con...

Abstract

The invention relates to a ground jacking type large-capacity hydraulic substation. 10 gas bottle large-capacity hydraulic substation trailers and a substation ground hydraulic jacking device are used in a matching manner, so as to effectively lower the lifting height and the weight of a trailer walking mechanism; not only is the large demand requirement of natural gas met, and also the safety and reliability of a gas supply device are guaranteed. According to the ground jacking type large-capacity hydraulic substation, a ground jacking device is integrated with a jacking system and a hydraulic pump and is provided with an automatic control system device; the structure is compact; the occupied area is small; the operation is flexible and convenient and the ground jacking device is safe, stable and reliable.

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...
