Abstract

The utility model discloses a slurry stopping device of a horizontal directional drilling machine, which comprises a power head, a slurry pump and a slurry hose, wherein the power head is connected with the slurry pump; the mud pump is communicated with the power head through a mud hose; and the slurry hose is provided with a slurry stopping device for intercepting the slurry in the pipe from flowing out. After the mud pump is shut down, the mud stopping device plays a role and closes a forward mud channel in time, so that mud in the hose assembly is retained in the hose after the hose assembly at the outlet of the mud pump reaches the stopping device and cannot flow outwards; only a little of mud flows out of the short joint of the power head and the front end of the mud stop, so that the mud consumption is saved, the construction cost is reduced, and the surrounding construction environment is protected.

Description

Slurry stopping device of horizontal directional drilling machine

Technical Field

The utility model relates to an auxiliary device for a horizontal directional drill, in particular to a slurry stopping device for a horizontal directional drilling machine.

Background

During the construction of the horizontal directional drill, the drilling cuttings can be taken out of the hole by mud circulation, and meanwhile, the mud also has the effects of stabilizing the hole wall, cooling and lubricating a drilling tool and the like, so that the mud has great use amount in the whole construction process, and plays an irreplaceable role. When the drill rod is loaded and unloaded in the guiding, hole expanding and back dragging stages, the mud pump can be closed without continuously working mud, but after the mud pump is closed, partial mud still exists in a mud pipeline between the mud pump and a short joint in front of the power head, and the mud in the pipeline can continuously splash and flow outwards, so that the waste of the mud is caused, and the aims of saving the mud consumption and reducing the construction cost are fulfilled.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a device which is characterized in that a slurry stop device is connected to a rotary joint at the rear end of a power head, so that the slurry consumption is saved, and the construction cost is reduced, and particularly relates to a slurry stop device of a horizontal directional drilling machine.

The utility model is realized by the following technical scheme that the mud stopping device of the horizontal directional drilling machine comprises a power head, a mud pump and a mud hose; the mud hose is arranged in the drag chain;

and the slurry hose is connected with a slurry stopping device for stopping slurry in the pipe from flowing out.

The preferable scheme of the mud stopping device of the horizontal directional drilling machine is as follows: and the power head is provided with a rotary joint fixedly connected with the slurry hose.

The preferable scheme of the mud stopping device of the horizontal directional drilling machine is as follows: the mud stopping device comprises a stop valve arranged on the mud hose, a stopping hydraulic oil cylinder for controlling the stop valve to be opened or closed, a mud stopping electromagnetic valve block and a separated electromagnetic valve;

the separated electromagnetic valve is used for receiving an electric signal when the mud pump is closed and transmitting the electric signal to the mud stop electromagnetic valve block, and the mud stop electromagnetic valve block controls the stop hydraulic oil cylinder to be opened or closed through the hydraulic hose.

The preferable scheme of the mud stopping device of the horizontal directional drilling machine is as follows: the stop hydraulic oil cylinder is fixedly connected with the stop valve through a connecting plate.

The utility model has the beneficial technical effects that: after the mud pump is shut down, the mud stopping device plays a role and closes a forward mud channel in time, so that mud in the hose assembly is retained in the hose after the hose assembly at the outlet of the mud pump reaches the stopping device and cannot flow outwards; only a little of mud flows out of the short joint of the power head and the front end of the mud stop, so that the mud consumption is saved, the construction cost is reduced, and the surrounding construction environment is protected.

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a shut-off valve connection;

in the figure: the device comprises a short joint 1, a power head 2, a stop valve 3, a slurry hose 4, a drag chain 5, a slurry pump 6, a rotary joint 7, a stop hydraulic oil cylinder 8, a slurry stop electromagnetic valve block 9, a separating electromagnetic valve 10 and a connecting plate 11.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the utility model. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Referring to fig. 1-2, as a first embodiment of the present invention, there is provided a mud stopping device for a horizontal directional drilling machine, comprising a power head 2, a mud pump 6, and a mud hose 4 communicated with the mud pump 6; the mud hose 4 is arranged in the drag chain 5;

and a slurry stopping device for intercepting the slurry flowing out of the pipe is arranged on the slurry hose 4.

And a rotary joint 7 fixedly connected with the slurry hose 4 is arranged on the power head 2.

The mud stop device comprises a stop valve 3 arranged on a mud hose 4, a stop hydraulic oil cylinder 8 for controlling the stop valve 3 to be opened or closed, a mud stop electromagnetic valve block 9 and a separated electromagnetic valve 10;

the separated electromagnetic valve 10 is used for receiving an electric signal when the mud pump 6 is closed and transmitting the electric signal to the mud stopping electromagnetic valve block 9, and the mud stopping electromagnetic valve block 9 controls the opening or closing of the stopping hydraulic oil cylinder 8 through a hydraulic hose.

The stop hydraulic oil cylinder 8 is fixedly connected with the stop valve 3 through a connecting plate 11.

The working principle and the method are as follows:

when the mud pump 6 is closed, the closing electric signal is transmitted to the separated electromagnetic valve 10, the separated electromagnetic valve 10 transmits the electric signal to the mud stop electromagnetic valve block 9, the mud stop electromagnetic valve block 9 controls the stop hydraulic oil cylinder 8 to be opened, the stop valve 3 is closed, so that a mud channel is formed, mud from a pipeline on the drag chain 5 acts through the stop valve 3, all the mud is stored in the pipeline, at the moment, only the mud hose 4 from the stop valve 3 to the rotary joint 7 and part of the mud exist in the power head 2, only the part of the mud flows out after the drill rod is disassembled, and the mud flowing waste between the pipeline from an outlet of the mud pump 6 to an outlet of the drag chain 5 is avoided; the length of a pipeline with the slurry is reduced, a large amount of slurry is prevented from being directly reserved, the waste of the slurry is reduced, and the cost is saved for customers.
