Problems solved by technology
Because the bolts generally have a large tightening torque here, and there is no power supply and other energy guarantees for field operations, they can only be tightened manually with a wrench and a booster rod, which is labor-intensive and leads to low work efficiency.

Embodiment Construction
[0021] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, not limited to this.
[0022] Such as Figure 1 to 9 As shown, the torque adjustment method of a tunnel pressure wrench according to the present embodiment includes a tank 1, a power cylinder 2, a plunger power pump 3, a torque converter, a reversing valve 5, a relief valve 6, and a manual drive member. The power cylinder 2, the plunger power pump 3, the reversing valve 5, and the relief valve 6 are provided in the tank 1, and the piston rod of the power cylinder 2 passes through the lower end of the tank 1 and the torque converter mechanism is connected. After the piston rod of the piston power pump 3 is connected to the manual drive member, the switch valve 5 is provided with a first port 51, a second port 52, a third port 53, a fourth port. 54 and fifth port 55, the first port 51, the second port 52, and the third port 53 of the switch val...

The invention discloses a torque adjusting method with a pressure adjusting knob. The method comprises an oil tank, a power oil cylinder, a plunger power pump, a torque conversion mechanism, a reversing valve, an overflow valve and a manual driving part. According to the method, maintenance personnel can act on the plunger power pump through the manual driving part, the plunger power pump pumps hydraulic oil to the power oil cylinder, then the power oil cylinder achieves switching of stretching and retracting actions under the action of the reversing valve, and meanwhile, linear thrust or linear tension of the power oil cylinder is converted into rotating torque through the torque conversion mechanism, so that larger torque can be output, fastening and dismounting of railway bolts or pipeline connecting flanges are achieved, the labor intensity of the maintenance personnel is greatly reduced, the working efficiency is improved, the size is small, the weight is light, carrying is convenient, the manual operation is achieved, and limitation of external conditions is avoided.
Description
Technical field [0001] The present invention relates to a torque adjustment method provided with a pressure regulator. Background technique [0002] At present, the railway maintenance personnel, the pipe maintenance personnel often need to disassemble the railway rail bolts and pipeline connection flanges in long-distance field patrols. Since the bolts are generally tightened here, there is no energy guarantee such as the field operation and other energy protection, and can only be used by the wrench and the stiff throttle, the labor intensity is large, and the work efficiency is low. Inventive content [0003] It is an object of the present invention to overcome the disadvantages described above, providing a torque adjustment method provided with a pressure regulator. [0004] In order to achieve the above object, the specific embodiments of the present invention are as follows: [0005] A torque adjustment method provided with a pressure regulator, including a fuel tank, a po...
