[0002] At present, rotary drilling rigs are widely used in foundation drilling projects, and their construction efficiency and quality have been recognized. In the past two decades, rotary drilling rigs have become commonly used equipment for bored pile construction. Rotary drilling rigs can be used with various drilling tools to meet construction operations in different geological conditions, from soft soil layers to sandy soil layers, gravel layers, weathered rock layers, hard rocks, etc.

[0003] In recent years, rotary drilling rigs have gradually been widely used in power construction foundation construction. Since power construction has higher requirements for drilling rigs: light weight of the whole machine, overall transportation, etc., ordinary rotary drilling rigs cannot meet the construction requirements or even reach the construction site.

[0004] Based on the above, when lightweight electric power rotary drilling rigs encounter hard rock formations, the drilling efficiency is low and the drill teeth are seriously worn, resulting in a significant increase in construction costs. When the hard rock exceeds 60Mpa, the drilling efficiency is extremely low or even impossible to drill. Therefore, a device is needed that can efficiently solve the problem of electric power rotary drilling rigs entering the rock. Utility Model Content

[0025] The dust removal system 2 mainly includes a water pump, a water tank, related pipelines, and a throttle valve.

[0026] In this embodiment: the drill rod 6 of the electric construction rotary drilling rig 1 is replaced with a pneumatic down-the-hole hammer drill rod, so that the drill rod 6 can be used for two purposes, and an air duct is set in the middle to realize air transmission; the drill rod 6 can achieve greater drilling depth by adding an extension section, and the depth depends on the air volume of the matching air compressor and the maximum lifting force of the main winch. The dust removal system 2 mainly includes a water pump, a water tank, related pipelines, a throttle valve, and software control to realize water pump flow control, and adjust the water flow according to the size of the borehole diameter, etc. The water in the water tank is set according to a certain flow rate through the water pump, and the water is transported to the air duct pipeline, and finally transported to the bottom of the down-the-hole hammer.

[0027] Among them, an airway swivel joint is arranged on the top of the drill pipe 4, and the drill pipe 6 is connected to the swivel joint 5 through a hexagonal joint 8 and a side axial pin shaft to realize the torque transmission and lifting force transmission of the drill pipe 6. The swivel joint 5 is divided into an external non-rotating body and a rotating body with an airway arranged inside to realize airway transmission. An interface for connecting with the main winch wire rope is arranged on the top to realize the connection between the wire rope and the swivel joint 5.

[0029] In this embodiment: the dust removal system 2 is provided to control the flow of the water pump, and the water is discharged from the exhaust air duct of the down-the-hole hammer in the form of water mist, and mixed with the dust to achieve dust reduction.

[0030] As a technical optimization solution of the utility model, the down-the-hole hammer drill 7 and the rotary drilling tool 9 are independently connected and installed to the bottom of the drill rod 6, and the down-the-hole hammer drill 7 and the rotary drilling tool 9 are used independently.

[0031] In the present embodiment: based on the electric power construction rotary drilling rig 1, a pneumatic down-the-hole hammer device is added, and the pneumatic down-the-hole hammer is used to impact and break the rock, so as to solve the problem that the electric power construction drilling rig cannot drill into the rock efficiently due to its light weight and small applied pressure. The matching pneumatic down-the-hole hammer device is seamlessly connected with the electric power construction rotary drilling rig 1 to achieve fast switching. By adding a conversion joint, the down-the-hole hammer drill tool 7 and the rotary drilling drill tool 9 can be switched, which is convenient and fast, and improves the construction efficiency.

[0034] As a technical optimization solution of the utility model, the bottom of the electric power construction rotary drilling rig 1 is provided with driving power through crawler wheels.

[0035] In this embodiment: the movement of the crawler wheels can provide driving power for the driving movement of the electric power construction rotary drilling rig 1.

[0036] In order to solve the large diameter pile hole operation of electric power construction foundation, a construction method is proposed:

[0037] Plum blossom pile construction is carried out by matching pneumatic down-the-hole hammers, and reasonable matching is carried out according to the diameter of the pile hole and the diameter of the down-the-hole hammer head. Usually, in order to reduce the equipment's requirements for the air volume of the air compressor, the diameter of the down-the-hole hammer head is generally between 300-400mm; according to the different diameters of the pile holes, when switching to rotary drilling construction, the hole can be drilled in one go or a graded drilling method can be used to achieve large-diameter pile hole operations.

[0038] Among them, it is necessary to explain how to add the connection structure:

[0039] Add air duct pipeline on the side of the main engine of the electric construction drilling rig (preferably using hard steel pipe);

[0040] An air pipe (preferably a rubber hose) bracket is added to the side of the main engine mast body to realize the transition connection between the hard steel pipe and the air duct rubber hose in the bracket area and the air duct rubber hose from the bracket to the swivel joint 5 on the top of the drill pipe 6, so as to prevent the rubber hose from being too long and causing scratches and interference, etc. At the same time, a rubber hose bracket roller is arranged on the mast body to guide and protect the rubber hose;

[0041] The drill rod 6 is replaced with a hollow single-layer drill rod, and both ends of the drill rod 6 adopt hexagonal head interfaces;

[0042] The lifting device of the electric construction drilling rig is replaced with an airway swivel joint, which connects the main winch wire rope and the drill rod 6, and is connected to the airway hose to realize the compressed air to the hollow tube of the drill rod and then to the working part of the impactor;

[0043] Dust removal system 2: The water in the water tank is pumped to the airway hose and then transported to the bottom of the down-the-hole hammer along with the compressed air; the dust generated by the down-the-hole hammer is atomized by water to reduce dust pollution;

[0044] In order to cooperate with the down-the-hole hammer construction operation, in the down-the-hole hammer construction mode, the power head speed and pressure are optimized and adjusted according to construction requirements.

[0045] Working principle: During construction, the down-the-hole hammer drill 7 and the rotary drilling tool 9 are used in coordination with each other according to actual needs. First, an airway swivel joint is set on the top of the drill rod 4. The drill rod 6 is connected to the swivel joint 5 through a hexagonal joint 8 and a side axial pin shaft to realize the torque transmission and lifting force transmission of the drill rod 6. The swivel joint 5 is divided into an external non-rotating body and a rotating body with an airway set inside to realize airway transmission. An interface for connecting the main winch wire rope is set on the top to realize the connection between the wire rope and the swivel joint 5. The drill rod 6 of machine 1 is replaced with a pneumatic down-the-hole hammer drill. The drill rod 6 can be used for two purposes. An air duct is set in the middle to realize air transmission. The drill rod 6 can achieve greater drilling depth by adding an extension section. The construction depth depends on the air volume of the matching air compressor and the maximum lifting force of the main winch. The water in the water tank is set according to a certain flow rate through a water pump, and the water is transported to the air duct pipeline and finally to the bottom of the down-the-hole hammer drill 7. Through the action of compressed air, the water is discharged from the exhaust air duct of the down-the-hole hammer drill 7 in the form of water mist and mixed with dust to achieve dust reduction.
