Description
The technical field is as follows:
the utility model relates to pneumatic spraying dust removal equipment based on a down-the-hole drill.
Background art:
along with the rapid development of economy, the construction of national traffic networks, hydraulic engineering and the like is rapidly developed, a large number of long and large tunnels appear, the complexity of the tunnels crossing the stratum is increased, and therefore, the construction process of reinforcing rock mass or stopping pressure-bearing water plugging of a grout wall by adopting advanced pre-grouting through a bad geological section is also rapidly developed.
However, during the advanced drilling construction, rock powder or concrete powder (hereinafter referred to as "rock powder") generated during the drilling process is blown out from the hole by high-pressure air, which not only affects the personal health of operators, but also the rock powder is blown down onto the down-the-hole drill and the supporting equipment, which easily causes the damage of the equipment, increases the maintenance difficulty and increases the maintenance cost.
The utility model content is as follows:
the utility model aims to solve the technical problem of providing the pneumatic spraying dust removal equipment based on the down-the-hole drilling machine, which can ensure the personal health of operators and simultaneously reduce the maintenance cost of the drilling machine and the matched equipment thereof.
The above object is achieved by: a first tee joint with a valve is arranged on a drilling machine air supply pipe close to a drilling machine, a vertical port of the first tee joint with the valve is connected with a first high-pressure hose, the other end of the first high-pressure hose is connected with a vertical port of a second tee joint with the valve, the valve end of the second tee joint with the valve is connected with the lower end of a first steel pipe joint through a hose, and spiral fins are fixed on the inner wall of the first steel pipe joint;
the first steel pipe section is fixed on the drilling machine control platform; and an air outlet is formed in one surface of the first steel pipe section facing the drilling machine control platform.
The other outlet of the second tee with the valve is connected with a second high-pressure hose; the water tank is provided with a water inlet, an air inlet and a water outlet; the one-way valve is installed on the second high-pressure hose, the other end of the second high-pressure hose is connected with the air inlet in the water tank, the third high-pressure hose is connected to the water outlet of the water tank, the end of the third high-pressure hose is connected with a second steel pipe joint, and the end of the second steel pipe joint is connected with a shower head to be used as a water outlet, so that a pneumatic high-pressure water gun is formed and is mainly used for removing rock powder on a drilling machine and matched equipment after drilling is finished.
The utility model has the advantages that: the rock powder around the operators can be blown off by the wind from the air outlet of the first steel pipe section, the personal health of the operators is protected, and meanwhile, fresh air is provided; the device can not only ensure the personal health of operators, but also reduce the maintenance cost of the drilling machine and the corollary equipment thereof. In addition, the device has simple structure, convenient use, low cost and simple manufacture and operation.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention.
The specific implementation mode is as follows:
the utility model is further illustrated with reference to fig. 1;
a first tee joint with a valve 3 is arranged on a drilling machine air supply pipe 2 close to a drilling machine 1, a vertical port of the first tee joint with the valve is connected with a first high-pressure hose 4, the other end of the first high-pressure hose is connected with a vertical port of a second tee joint with the valve 6, the valve end of the second tee joint with the valve 6 is connected with the lower end of a first steel pipe joint 7 through a hose, and spiral fins are fixed on the inner wall of the first steel pipe joint;
the first steel pipe section is fixed on a drilling machine control platform 5; the one side that first steel pipe section faced the rig and controlled the platform is equipped with the air outlet, and the wind that comes out through the air outlet of first steel pipe section can blow off the peripheral rock powder of operating personnel, and protection operating personnel's personal is healthy, provides fresh air simultaneously.
The other outlet of the second tee joint with a valve 6 is connected with a second high-pressure hose 8; the water tank is characterized by also comprising a water tank 10 with a tank cover, wherein the water tank is provided with a water inlet 11, an air inlet 12 and a water outlet 13; the second high-pressure hose is provided with a check valve 9, the other end of the second high-pressure hose is connected with an air inlet on the water tank, a water outlet of the water tank is connected with a third high-pressure hose 14, the tail end of the third high-pressure hose is connected with a second steel pipe joint 15, and the tail end of the second steel pipe joint is connected with a shower head 16 to be used as a water outlet, so that a pneumatic high-pressure water gun is formed and is mainly used for removing rock powder on a drilling machine and matched equipment after drilling.
