Abstract

A pressure maintaining oil cylinder system of a holder of a horizontal directional drilling machine is used in the technical field of clamps of horizontal directional drilling machines. According to the pressure maintaining oil cylinder system of the holder of the horizontal directional drilling machine, a piston rod and a piston assembly are installed in an oil cylinder body provided with a flange, an energy accumulator cylinder body and an air bag are integrated on the oil cylinder body and are installed in a rodless cavity of the oil cylinder body, and a pilot operated check valve is integrated on an oil port of the air bag. Due to the fact that the energy accumulator cylinder body and the air bag are integrated on the oil cylinder body, the problems, existing in a traditional system, of complexity, the large number of hydraulic components, large installation space and high installation difficulty are solved fundamentally, and more importantly, the problem that according to the prior art, due to the fact that the position where the energy accumulator cylinder body is located is close to a drilling rig, a connecting hose can be scratched easily by the drilling rig to cause accidents is solved; the larger the diameter of an oil cylinder is, the longer the travel distance is and the more obvious the effect is. The oil cylinder not only can be applied to a clamp of the horizontal directional drilling machine, but also can be widely used in systems needing short-time pressure maintenance.

Description

Gripper of horizontal position drilling machine pressurize cylinder system
Technical field
The utility model relates to horizontal directional drilling machine clamp technical field, is a kind of gripper of horizontal position drilling machine pressurize cylinder system specifically.
Background technique
Clamp belongs to the drilling rod loading and unloading supplementary equipment of horizontal directional drilling machine, and along with progressively improving of drilling rig technique, clamp has been the indispensable part of rig.At present, the clamp structure of largest portion is all used hydraulic jack as main actuator, and application is very ripe.But,, because there are leakage problem in oil cylinder and corresponding control valve member, caused clamp structure all to have the problem of pressure release.The generation of pressure release problem, the most direct result be exactly while causing shackle the chucking power of clamp reduce, even disappear, cause subordinate's drilling rod when shackle to rotate, cause tool joint injured, have a strong impact on the working life of drilling rod, cause drilling rod to damage too early.
For addressing this problem, the most general solution is to set up hydraulic lock (or equilibrium valve) and accumulator on oil hydraulic circuit.As shown in Figure 2, sequence number 1 is clamping cylinder; Sequence number 2 is pressure gauge; Sequence number 3 is accumulator; Sequence number 4 is equilibrium valve; Sequence number 5 is control valve.Through using, the method has really overcome above-mentioned deficiency to a certain extent.But adopt the most direct consequence of the method to cause exactly complex system, increased the quantity of hydraulic element, increased installing space, installation difficulty increases a lot.Prior,, drilling tool very easily occurs scratch connecting hose and have an accident near drilling tool due to this position.
Summary of the invention
For overcoming the deficiency of existing level directional drilling machine clamp holder pressurize cylinder system, invention order of the present utility model is to provide a kind of gripper of horizontal position drilling machine pressurize cylinder system, can effectively solve pressurize and installing space problem, reduce simultaneously rate of breakdown, improve stabilization of equipment performance.
For achieving the above object, in the cylinder block with flange of the present utility model, piston rod and piston assembly are housed, it is characterized in that: be integrated with accumulator cylinder and air bag on cylinder block; Described accumulator cylinder and air bag are arranged in the rodless cavity of cylinder block; Be integrated with Pilot operated check valve on the hydraulic fluid port of air bag.
The utility model compared with prior art, by accumulator cylinder and air bag being integrated among cylinder block, fundamentally solved the problem that legacy system is complicated, hydraulic element are various, installing space is large, installation difficulty is high, the more important thing is that having avoided this position, near drilling tool, drilling tool occurs easily scratches connecting hose and have an accident; And cylinder diameter is larger, and stroke is longer, and effect is obvious.This oil cylinder not only can be applied to can also be widely used in the system of pressurize in short-term on the clamp of horizontal directional drilling machine.

Fig. 1 is structure diagram of the present utility model.
Fig. 2 is the prior art structure diagram.
Embodiment
As shown in Figure 1, piston rod 1 and piston assembly 4 are housed in the cylinder block 3 with flange 2, piston assembly 4 has been divided into two parts with cylinder block 3, rod chamber 7 and rodless cavity 8, a side integrated installation at the rodless cavity 8 of cylinder block 3 has accumulator cylinder 5 and air bag 6, on hydraulic jack cylinder bottom 10, can integrated Pilot operated check valve 9.
Accumulator cylinder 5 and air bag 6 are directly installed at the bottom of oil cylinder in 10, when piston rod 1 and piston assembly 4 work, be full of high-voltage oil liquid in rodless cavity 8, hydraulic cylinder piston rod 1 and piston assembly 4 are stretched out together, rodless cavity 8 spaces increase, and rod chamber 7 spaces dwindle, until piston rod 1 and piston assembly 4 stretch out fully, perhaps meet with obstruction and be forced to stop, rod chamber 7 spaces no longer change.High pressure oil continues to pour rodless cavity 8, and under the effect of high pressure oil, air bag 6 starts compressed, and rodless cavity 8 internal pressures start to raise, and store high pressure oil, until reach the authorized pressure value, pressure and intracapsular pressure balance in rodless cavity 8.Outside stops supplying with high pressure oil in rodless cavity 8, Pilot operated check valve 9 is closed, along with time history, high pressure oil in rodless cavity 8 leaks in rod chamber 7 by piston assembly 4, pressure in rodless cavity 8 starts to reduce, and air bag 6 starts to expand, thereby keeps the pressure in rodless cavity 8 relatively stable, realize the pressure maintaining effect in hydraulic jack rodless cavity 8, until the hydraulic energy in air bag 6 discharges fully.
Along with the increase of cylinder block 3 diameters, the larger air bag of enough space mounting 6 just can be arranged, air bag 6 increases, and just can store more high pressure energy, is conducive to extend the complete release time of pressure of air bag 6.Along with the increase of cylinder diameter, the leakage rate of piston assembly also can increase relatively, but the volume increase of air bag 6 has been lacked much relatively, thereby along with the increase of cylinder diameter, the pressurize effect increases on the contrary to some extent.
