Description

A kind of push-pull mechanism reinforcement control system of horizontal directional drilling machine
Technical field
The present invention relates to horizontal directional drilling machine manufacturing field, the push-pull mechanism reinforcement of more particularly to a kind of horizontal directional drilling machine Control system.
Background technology
Horizontal directional drilling machine is a kind of engineering machine that a variety of subsurface utilities are laid under conditions of not excavating earth surface face Tool, it is widely used in the laying of the underground piping in the fields such as water supply, electric power, communication, natural gas, oil, pipeline, it is suitable for The various bad grounds such as sandy soil, clay, cobble, rock.
The push-pull mechanism of horizontal directional drilling machine must provide sufficiently large push-pull effort, can ensure construction it is smooth into Row, the push-pull mechanism of horizontal directional drilling machine generally provide push-pull effort by hydraulic motor.Fig. 1 is referred to, it illustrates the prior arts In horizontal directional drilling machine push-pull mechanism control system, including fuel tank 101, hydraulic pump 102, manual multiple-way valve 103, the first liquid Pressure motor 104, the second hydraulic motor 105.
The push-pull mechanism control system operation principle of above-mentioned horizontal directional drilling machine is as follows:Hydraulic pump 102 is inhaled from fuel tank 101 Oil, manually multi-way valve 103 is to the first hydraulic motor 104,105 fuel feeding of the second hydraulic motor, so as to drive the first hydraulic pressure horse It does work up to the 104, second hydraulic motor 105.It, can be by adjusting manual multiple-way valve 103 when drilling machine needs larger push-pull effort On overflow valve pressure, the overflow valve pressure on manual multiple-way valve 103 is tuned up, to realize the larger push-pull effort of push-pull mechanism. Usually in the case where ensureing the work efficiency of horizontal directional drilling machine, the relief valve set pressure on manual multiple-way valve 103 is 18MPa.
But it returns and drags or the operating modes such as rock are, it is necessary to which push-pull mechanism output bigger is pushed away in extra long distance drilling, large aperture Pulling force.If push-pull effort is inadequate, it is easy to drilling rod, drilling tool be caused to be stuck, and the equipment for exchanging more large slide force is needed Construction, causes huge economic loss.In order to export the push-pull effort of bigger, and the overflow valve pressure on manual multiple-way valve 103 Maximum is transferred to, since the engine power of driving hydraulic pump 102 is limited, push-pull effort improves, but the rotation of horizontal directional drilling machine Rotation mechanism, slush pump mechanism efficiency will accordingly be lower, so as to influence working effect.
In summary, it is necessary to design a kind of new horizontal directional drilling machine push-pull mechanism reinforcement control system, Ji Nengti The maximum push-pull effort that horizontal directional drilling machine can be output is risen, and can guarantee the work efficiency of horizontal directional drilling machine.
The content of the invention
The purpose of the present invention is in view of the above-mentioned drawbacks of the prior art, providing a kind of push-and-pull machine of horizontal directional drilling machine Structure reinforcement control system, it is simple in structure, at low cost, reinforcement effect is apparent, it can ensure the construction effect of horizontal directional drilling machine simultaneously Rate, and greatly improve the adaptability of horizontal directional drilling machine reply bad ground and special operation condition.
The present invention to achieve the above object the technical solution adopted is that:A kind of push-pull mechanism reinforcement control of horizontal directional drilling machine System processed, including fuel tank, hydraulic pump, manual multiple-way valve, the first hydraulic motor, the second hydraulic motor, the oil outlet of hydraulic pump leads to Oil pipe I is crossed to be connected with an oil inlet of manual multiple-way valve, an oil outlet of manual multiple-way valve again by oil pipe II respectively with The oil inlet of first hydraulic motor and the second hydraulic motor connects, and the oil outlet of the first hydraulic motor and the second hydraulic motor passes through Oil pipe III is connected with another oil inlet of manual multiple-way valve, another oil outlet of manual multiple-way valve passes through oil pipe IV and fuel tank Connection, further includes manual overflow valve and normal open two-position three way magnetic valve, the oil inlet of manual overflow valve passes through oil pipe V and normal open The oil outlet connection of two-position three way magnetic valve, the oil outlet of manual overflow valve are connected by oil pipe VI with fuel tank, normal open two three The oil inlet of three-way electromagnetic valve is connected by the oil pipe I between oil pipe VII and hydraulic pump and manual multiple-way valve, normal open two-position three way electricity Another oil outlet of magnet valve is connected by oil pipe VIII with fuel tank.
The present invention further technical solution be:The pressure value of the overflow valve of the manual multiple-way valve is 25MPa.
The present invention further technical solution be:The pressure value of the manual overflow valve is 18MPa.
The technique effect of the present invention:The present invention is compared with the push-pull mechanism control system of horizontal directional drilling machine in the prior art Compared with raising hydraulic pump and the first hydraulic motor, the pressure rating of the second hydraulic motor add one often in hydraulic circuit Logical two-position three way magnetic valve and a manual overflow valve need to increase a control valve, two parallel connections compared to other reinforcement modes Motor is simpler, need not change too many component, and simple in structure at low cost, reinforcement effect is apparent, and the fan-out capability of push-pull effort obtains To being obviously improved, while ensure the construction efficiency of horizontal directional drilling machine, and it is complicated greatly to improve horizontal directional drilling machine reply Stratum and the adaptability of special operation condition.
The push-pull mechanism reinforcement control system of horizontal directional drilling machine of the present invention is made into one with reference to the accompanying drawings and examples The explanation of step.
