In the prior art, there are construction equipment specifically designed for drilling soil or rock, but in general, the design is relatively simple and cannot efficiently play the role of drilling soil. For example, the prior art discloses a drilling device, in which a lifting plate is provided on the frame, an adjusting seat is rotatably provided on the lifting plate, a fixed seat is rotatably provided on the adjusting seat, an adjusting mechanism is provided on the adjusting seat, a hydraulic cylinder is provided on the upper side of the fixed seat, a fixed plate is connected to the output end flange of the hydraulic cylinder, a vertical drilling motor is provided on the fixed plate, a drill bit is provided at the output end of the drilling motor, and a dust suction mechanism is provided on the fixed plate. This technology can adjust the position of the drill bit through the setting of the frame and the lifting plate, and use the adjustment mechanism to adjust the drilling angle so that the drill bit is perpendicular to the position where the hole needs to be drilled, and the drilling function is realized under the action of the drilling motor and the hydraulic cylinder, thereby effectively saving the time required to set up supporting equipment when drilling, and improving the drilling efficiency when drilling in large quantities;

DETAILED DESCRIPTION

[0056] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0057] like Figures 1 to 8 As shown, a construction drilling device described in the present invention includes a control mechanism, a bearing mechanism, a drilling mechanism, a dust prevention mechanism and a reflux mechanism.

[0058] The drilling mechanism includes a drill rig 6 and a connector 8, wherein the connector 8 is used to connect the drill bit and the output shaft of the drill rig 6, wherein the connector 8 is connected to the output shaft of the drill rig 6, and the drill bit is detachably mounted on the connector 8. By controlling the rotation of the drill bit, a hole is drilled in the rock wall of the construction site to facilitate the installation and anchoring of the support bracket.

[0059] The supporting mechanism includes a supporting plate 2 and a mounting plate 3 for mounting a drilling rig 6. The mounting plate 3 is movably arranged on the side wall of the supporting plate 2. The mounting plate 3 is used to provide an installation position for the drilling rig 6. The movement of the drilling rig 6 is controlled by adjusting the position of the mounting plate 3 to facilitate drilling at different positions.

[0060] The movement of the load-bearing plate 2 and the mounting plate 3 is controlled by a control mechanism, which includes a mobile carrier 1, a control telescopic cylinder 11, a balance telescopic cylinder 10, a transverse slide rail 9 and a vertical slide rail 12. The control telescopic cylinder 11 and the balance telescopic cylinder 10 are common hydraulic cylinders, the transverse slide rail 9 and the vertical slide rail 12 are common hydraulic slide rails, and the mobile carrier 1 is a crawler carrier.

[0061] The mounting ends of the control telescopic cylinder 11 and the balancing telescopic cylinder 10 are both installed on the mobile carrier 1, and the movable ends of the control telescopic cylinder 11 and the balancing telescopic cylinder 10 are both hinged to the back of the supporting plate 2, wherein the control telescopic cylinder 11 and the balancing telescopic cylinder 10 are arranged alternately, and the supporting plate 2 is controlled to move along the X-axis direction by telescoping the movable ends of the control telescopic cylinder 11 and the balancing telescopic cylinder 10.

[0062] The fixed end of the vertical slide rail 12 is fixedly connected to the outer wall of the bearing plate 2 , and the fixed end of the transverse slide rail 9 is connected to the movable end of the vertical slide rail 12 . The transverse slide rail 9 is controlled by the vertical slide rail 12 to be raised and lowered along the Z-axis direction.

[0063] The outer wall of the mounting plate 3 is connected to the movable end of the transverse slide rail 9, and the transverse slide rail 9 controls the mounting plate 3 to move along the Y-axis direction.

[0064] During the anchor hole drilling construction, the mobile vehicle 1 is first driven to the construction area, and then the position of the drill bit is fine-tuned in the X, Y and Z axis directions to facilitate alignment of the drill bit with the drilling position.

[0065] The dust prevention mechanism includes a water curtain nozzle 5 and a cooling nozzle 4. The water curtain nozzle 5 and the cooling nozzle 4 are evenly arranged on the mounting plate 3 in a ring shape along the axis of the connector 8. The nozzle of the cooling nozzle 4 is inclined toward the drill bit. The cooling nozzle 4 is connected to an external water source. During drilling construction, water is sprayed toward the drill bit to cool the drill bit, thereby preventing the drill bit from overheating.

[0066] The nozzles of the water curtain nozzles 5 are tilted, and multiple water curtain nozzles 5 spray water synchronously to form a cylindrical water curtain. The drill construction position is located within the water curtain, which can achieve the effect of dust reduction and prevent workers from inhaling dust as much as possible.

[0067] The reflux mechanism includes a collecting box 14 , an elastic bucket 13 and a control pump 7 . The collecting box 14 is fixedly mounted on the mounting plate 3 , and the connector 8 passes through the collecting box 14 . A sealed bearing is provided at the contact position between the connector 8 and the collecting box 14 .

[0068] The elastic bucket 13 is fixedly installed on the upper end of the collection box 14 and is used to filter the falling water droplets. The outer portion of the elastic bucket 13 is an elastic non-woven fabric, and a sponge is sewn inside the non-woven fabric. When the drill bit drills a hole, dust, sand and coolant fall down. When the coolant flows along the outer wall of the elastic bucket 13, it penetrates downward into the interior of the collection box 14 due to gravity, thereby filtering and collecting the refluxed coolant.

[0069] As the drill bit rubs against the rock wall when drilling, the friction work is converted into internal energy, which is absorbed by the coolant. The heated coolant is collected by the collection box 14.

[0070] The input end of the control pump 7 is connected to the inner cavity of the collection box 14, the water curtain nozzle 5 is provided with two input ends, the output end of the control pump 7 is connected to one of the input ends of the water curtain nozzle 5, and the heating coolant collected in the collection box 14 is controlled by the control pump 7 to be sprayed out by the water curtain nozzle 5, thereby generating a hot flow water curtain.

[0071] In this embodiment, the coolant is heated by the useless heat energy generated when the drill bit is working. The water vapor and water droplets generated after atomization can more effectively absorb dust particles in the air. The evaporation rate of hot water is higher, which can increase the air humidity to a certain extent, reduce the floating and diffusion of dust in the air, and thus enhance the dust reduction effect.

[0072] The other input end of the water curtain nozzle 5 is connected to an external water source. A water level sensor is arranged in the collection box 14. When the liquid level in the collection box 14 drops to a set minimum liquid level, the control pump 7 stops working. At this time, water is supplied to the water curtain nozzle 5 through the external water source.

[0073] As a preferred embodiment of the present invention, a transmission boss 18 is fixedly mounted on one end of the elastic bucket 13 away from the collecting box 14. A plurality of transmission bosses 18 are arranged in a ring shape, wherein the side walls of the transmission bosses 18 are arranged inclined.

[0074] When sand and gravel fall and hit the outside of the elastic bucket 13 , the elastic bucket 13 will shake. In order to facilitate the shaking of the elastic bucket 13 , a sliding seal is provided at the contact position between the elastic bucket 13 and the connector 8 to prevent sand and gravel from falling into the gap between the connector 8 and the elastic bucket 13 .

[0075] A transmission lever 17 is fixedly installed on the radial outer wall of the connector 8. When the connector 8 rotates, the transmission lever 17 is driven to rotate, and the transmission lever 17 presses the transmission boss 18, thereby pressing the elastic bucket 13 downward. After the transmission boss 18 is separated from the transmission lever 17, the elastic bucket 13 is reset, thereby realizing the up and down shaking of the elastic bucket 13, preventing sand and gravel from accumulating on the outer wall of the elastic bucket 13, and maintaining the filtration efficiency of the elastic bucket 13.

[0076] A mounting cylinder 15 is fixedly mounted on the inner wall of the collecting box 14 , a support rod 16 is elastically mounted on the inner wall of the mounting cylinder 15 , a spring is arranged inside the mounting cylinder 15 , and the support rod 16 is elastically connected to the inner wall of the mounting cylinder 15 via the spring.

[0077] One end of the support rod 16 extends to the outer wall of the mounting tube 15 and fits with the bottom surface of the elastic bucket 13. The support rod 16 can assist the elastic bucket 13 in resetting upward when sand and gravel fall, and can prevent the elastic bucket 13 from sinking inward as much as possible.

[0078] As a preferred embodiment of the present invention, a guide plug 25 is slidably installed on the inner wall of the mounting tube 15, and a sealing rubber is provided on the outer wall of the guide plug 25, which slides in contact with the inner wall of the mounting tube 15. The upper end surface of the guide plug 25 is fixedly connected to the bottom end of the support rod 16, and the sliding support rod 16 drives the guide plug 25 to slide synchronously.

[0079] An air inlet and an exhaust pipe 24 are provided at the bottom of the installation tube 15 . A one-way valve is provided in the air inlet, and the one-way valve is used to control the external air from entering the inner cavity of the installation tube 15 .

[0080] A recoil pipe 21 is fixedly installed on the inner wall of the collection box 14, and the outer wall of the recoil pipe 21 is in contact with the bottom surface of the elastic bucket 13, and an exhaust hole is opened in the recoil pipe 21 near the elastic bucket 13. Air is introduced into the recoil pipe 21 and then discharged from the exhaust hole, and air is blown outward from the elastic bucket 13 to realize recoil cleaning of the elastic bucket 13, thereby preventing sand and gravel from clogging the elastic bucket 13, which is used to improve the cleaning efficiency of the elastic bucket 13.

[0081] One end of the recoil pipe 21 is connected to the exhaust pipe 24, and the sliding guide plug 25 controls the gas inside the mounting tube 15 to be discharged through the recoil pipe 21, so that when sand and gravel hit the elastic bucket 13, the exhaust pipe 24 is synchronously controlled to exhaust and the elastic bucket 13 is recoil-cleaned.

[0082] A baffle ring 33 is fixedly mounted on the inner wall of the exhaust pipe 24 . A truncated cone-shaped through hole is provided in the baffle ring 33 . The gas inside the mounting tube 15 is discharged into the exhaust pipe 24 through the baffle ring 33 .

[0083] A mesh plate 34 is fixedly mounted on the inner wall of the exhaust pipe 24 , a transmission rod 35 is slidably mounted inside the mesh plate 34 , and an outer wall of the transmission rod 35 is slidably fitted to the inner wall of the mesh plate 34 .

[0084] The side wall of the mesh plate 34 is elastically mounted with a sealing plug 20 for sealing the blocking ring 33. The outside of the sealing plug 20 is connected to the mesh plate 34 via a spring. The elastic force of the spring pushes the sealing plug 20 so that the sealing plug 20 has a tendency to fit the blocking ring 33 in real time.

[0085] The side of the sealing plug 20 close to the inner cavity of the installation cylinder 15 is fixedly connected to the outer wall of the transmission rod 35. The sliding transmission rod 35 controls the sealing plug 20 to separate from the baffle ring 33. At this time, the exhaust pipe 24 and the inner cavity of the installation cylinder 15 are connected.

[0086] During the downward movement of the guide plug 25, the air inside the mounting tube 15 is compressed. As the air pressure increases, the transmission rod 35 is slid, thereby controlling the connection between the exhaust pipe 24 and the inner cavity of the mounting tube 15. At this time, the pressurized gas is discharged through the recoil pipe 21, thereby improving the efficiency of recoil cleaning.

[0087] The inner wall of the mounting tube 15 is fixedly mounted with a mounting frame 32, and the outer wall of the mounting frame 32 is rotatably mounted with a transmission plate 37 through a torsion spring. After the transmission plate 37 is rotated, the transmission plate 37 is reset with the assistance of the torsion spring.

[0088] A connecting plate 36 is rotatably mounted on one end of the transmission rod 35. The connecting plate 36 and the transmission plate 37 are hinged by a pin shaft. A force plate 38 is provided at the connecting position of the connecting plate 36 and the transmission plate 37. The pin shaft is fixedly mounted on the outer wall of the transmission plate 37. When the connecting plate 36 and the transmission plate 37 are in a horizontal state, the force plate 38 is vertically facing upward.

[0089] A pressing rod 31 for pressing the force plate 38 is fixedly installed at the bottom of the guide plug 25. When the guide plug 25 slides downward, the pressing rod 31 is controlled to move synchronously until the pressing rod 31 contacts the force plate 38. At this time, the connecting plate 36 and the transmission plate 37 of the force plate 38 are deflected, pulling the transmission rod 35 to slide, so that a gap is generated between the baffle ring 33 and the sealing plug 20. At this time, the pressurized gas is discharged to recoil and clean the elastic bucket 13, so as to realize automatic exhaust of the inner cavity of the installation cylinder 15.

[0090] As a preferred embodiment of the present invention, a transfer box 19 is fixedly installed on the inner wall of the collection box 14. The inner cavity of the transfer box 19 is connected to the input end of the control pump 7 through a conduit. The inner cavity of the transfer box 19 is communicated with the inner cavity of the collection box 14 to facilitate the control pump 7 to absorb the hot water in the inner cavity of the collection box 14.

[0091] The inner wall of the adapter box 19 is fixedly mounted with a mounting bracket 23, which is hollowed out and made of elastic material. The mounting bracket 23 is made of elastic plastic and has a hollow design to facilitate the passage of coolant.

[0092] A filter layer 22 is fixedly mounted on the side wall of the mounting bracket 23 . The filter layer 22 is made of elastic material and is a common sponge. The filter aperture of the filter layer 22 is not higher than the filter aperture of the elastic bucket 13 . The filter layer 22 is used to filter the hot water inside the collection box 14 .

[0093] A movable rod 29 is fixedly installed on one side of the filter layer 22. When the filter layer 22 is filtering, the movable rod 29 is pulled and then released, and the filter layer 22 is reset by its own elastic force, thereby controlling the shaking of the filter layer 22, preventing impurities from adhering to the outer wall of the filter layer 22, and maintaining the filtering efficiency of the filter layer 22.

[0094] One end of the movable rod 29 extends to the inner cavity of the collection box 14 and is fixedly installed with a transmission block 27. The side wall of the transmission block 27 is inclined. The transmission block 27 is pressed along the inclined surface of the transmission block 27 to control the sliding of the movable rod 29, thereby driving the filter layer 22 to deform.

[0095] A connecting shaft 28 is fixedly installed on the bottom surface of the guide plug 25. The bottom of the connecting shaft 28 passes through the mounting tube 15 and is fixedly installed with a pressing block 26 for pressing the transmission block 27. A sliding seal is provided at the contact position between the connecting shaft 28 and the mounting tube 15 to achieve sealing at the bottom of the mounting tube 15.

[0096] During the sliding of the guide plug 25 , the connecting shaft 28 is driven to slide back and forth. At this time, the pressing block 26 presses the transmission block 27 to drive the movable rod 29 to slide, thereby controlling the deformation of the filter layer 22 and achieving self-cleaning of the filter layer 22 .

[0097] A tapping shaft 30 is elastically mounted on the outer wall of the mounting bracket 23. The tapping shaft 30 is connected to the mounting bracket 23 through a spring. The tapping shaft 30 is in contact with the side of the filter layer 22 away from the movable rod 29. When the movable rod 29 presses the filter layer 22, the tapping shaft 30 is pressed synchronously. At this time, the spring stores elastic potential energy. When the spring releases the elastic potential energy, it drives the tapping shaft 30 to perform simple harmonic motion, thereby repeatedly tapping toward one side of the filter layer 22, thereby further improving the efficiency of removing the attachments on the outer wall of the filter layer 22.

[0098] In order to increase the kinetic energy of the knocking shaft 30 when it hits the filter layer 22, a counterweight block is provided at one end of the knocking shaft 30 away from the filter layer 22. By increasing the counterweight, the instantaneous kinetic energy during the impact can be effectively increased.

[0099] like Fig. 9 As shown, a supporting structure construction method, which adopts the above-mentioned construction drilling device, comprises the following steps:

[0100] A1. Move the mobile vehicle 1 to the construction area, and control the installation plate 3 to move so that the drill bit at the output end of the drilling machine 6 is aligned with the drilling position;

[0101] A2. Start the drilling machine 6 to start drilling. While drilling, the water curtain is sprayed out through the water curtain nozzle 5, and the cooling nozzle 4 sprays coolant toward the drilling position;

[0102] A3, the falling coolant falls to the outer wall of the elastic bucket 13, enters the inner cavity of the collecting box 14 after preliminary filtration, and the collecting box 14 collects the heated coolant and further filters it through the filter layer 22, and then the heated coolant is controlled by the control pump 7 to be sprayed out by the water curtain nozzle 5; after the drilling is completed, the drill bit is withdrawn and the drill hole is rinsed through the cooling nozzle 4;

[0103] A4. Drive chemical anchor bolts into the boreholes to chemically bond the chemical anchor bolts to the inner wall of the boreholes. Build a steel arch frame for support at the construction site. Use an arch frame connecting plate locator to locate and cut the steel arch frame. Connect the steel arch frame to the chemical anchor bolts so that the chemical anchor bolts can reinforce the steel arch frame.

[0104] For example, in tunnel construction sites, due to the uncertainty of the construction environment, steel arches are needed for support to ensure their stability. However, in actual construction, the steel plate reinforcement during the connection of the steel arch is often a weak link in the arch processing, and the welding of the steel and the connecting plate of each unit of the steel arch is independent, which can easily lead to the inability to accurately align the arch units for installation.

[0105] The device and method provided in this embodiment can solve the problem of reinforcement and positioning of steel arch frames. During construction, when prefabricating steel arch frames, arch frame connection plate locators are used to position and cut the arch frames, and chemical anchor bolts are used to reinforce the arch frames on site. Through the application of this tooling, the connection of the steel arch frames is effectively ensured. The installation of chemical anchor bolts is efficient and convenient, and the chemical anchor bolts are used to reinforce the steel arch frames in the existing high-speed railway tunnel lining. The chemical anchor bolts are quickly solidified, saving construction time, and there is no expansion and extrusion stress on the substrate. It is suitable for heavy loads and various vibration loads; it is acid and alkali resistant, heat resistant, fireproof, and has low temperature sensitivity. The device and method can solve the reinforcement problem of the arc-shaped steel arch frame connecting the steel plate in the tunnel of the existing high-speed railway line. It breaks the limitations of traditional reinforcement methods on construction environment and material selection, and solves the problems of substrate damage and low construction efficiency that may be caused by traditional reinforcement methods through chemical anchor bolts with their unique chemical bonding properties.
