State hydraulic cylinder upper end and oil circuit board be installed, fuel tank, oil meter and oil pump are fixed with the oil circuit board, be provided with the oil circuit board into
Oil circuit and vent line, wherein the in-line connects hydraulic cylinder, fuel tank and the oil pump, the vent line connects the hydraulic pressure
Cylinder, oil meter and fuel tank.The technology is detected by carrying out pressure to track during hydraulic pressure legacy system, so as to can realize it is reliable,
Smoothly pressure, so measurement are more accurate;The track fixture of design can easily realize the folder of the utility model and track
Hold and dismantle.
But pass through much time using and find, though it can be arrived to pressure requirements using Manual pressurization pump, its oil circuit complexity,
The problems such as easy failure of check valve is more.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided a kind of hydraulic drive screw press formula branch residual voltage
Tester, this technology are used hydraulic transmission mode, pressurizeed using helicoidal pump, simplify oil circuit, save check valve, reach few failure,
Even trouble-free purpose.Further mitigate weight simultaneously, improve the simplicity of operation.
Used technical scheme is as follows to achieve these goals for the utility model：
A kind of hydraulic drive screw press formula branch residual voltage tester, it includes rail clamping device, branch pressure head, screw rod
Adjusting means, screw press pump and oil cylinder；The oil cylinder is fixedly mounted on rail clamping device, and the branch pressure head is arranged on

Connection；And it is additionally provided with extension spring between projection handle and vertical arm.
The utility model also includes portable handle, and the portable handle is fixedly mounted on transverse arm.
The utility model utilizes hydraulic transmission principle, using the rail clamping device of brief and practical, the hand of screw press formula
Dynamic force (forcing) pump, make hydraulic circuit is simple, part is few, failure is few, fault rate is low, small volume, it is in light weight, be convenient for carrying, be easy to grasp
Make, safe ready.
Secondly the utility model considerably reduces the weight of the tester, more just by reducing oil circuit and check valve
Portable belt, particularly railway worker are needed along track travel to rail circuit test, without any vehicles, are all adopted
With walking, and generally farther out, therefore the weight weight of equipment keeps muscle power to have relatively straightforward pass to travel distance to test man
System.Therefore the utility model can effectively improve the operating efficiency of staff, while reduce working strength.
