Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a building foundation drilling device. Background Art

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, the demand for efficient, precise and safe drilling equipment is increasing. In addition, with the improvement of environmental awareness, there is also a high market demand for low-noise, low-vibration and low-emission drilling equipment. Therefore, the market for building foundation drilling equipment has great potential and development space.

[0003] The existing building foundation drilling usually uses a rotary drilling rig to drill foundation pile holes. When the rotary drilling rig is working, it will bring soil and gravel to the ground through the spiral chip groove on the surface. The soil and gravel are accumulated on the edge of the pile hole. Under the influence of the weight of the soil and gravel, the pile hole mouth position is likely to collapse, and the soil and gravel may fall back into the hole, which may easily cause the drill bit to be stuck in the pile hole, affecting the subsequent grouting process. The fallen sand and gravel may easily damage the drill bit surface, requiring the operator to use a shovel to collect them. Since the rotary drilling rig is usually directly connected to the drive shaft without any protection measures on the outside, the personal safety of the operator cannot be guaranteed during the shoveling process. At the same time, the dust generated after the sand and gravel are raised can easily pollute the construction environment and affect the physical and mental health of the operator. Therefore, the present application provides a building foundation drilling device to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a building foundation drilling device to solve the problem that the existing building foundation drilling usually uses a rotary drilling drill to drill foundation pile holes. When the rotary drilling drill is working, it will bring soil blocks and gravel to the ground through the spiral chip groove on the surface. The soil blocks and gravel are accumulated on the edge of the pile hole. Under the influence of the weight of the soil blocks and gravel, the pile hole mouth position is easily collapsed. The soil blocks and gravel may fall back into the hole, which is easy to cause the drill bit to be stuck in the pile hole, affecting the subsequent grouting process. The fallen sand and gravel are easy to damage the surface of the drill bit, and the operator needs to use a shovel to collect them. Since the rotary drilling drill is usually directly connected to the drive shaft and there is no protection measure on the outside, the personal safety of the operator cannot be guaranteed during the shoveling process.

[0026] like Figures 1 to 13 As shown, an embodiment of the present invention provides a building foundation drilling device, including a crawler vehicle 1, a turning platform 2 is arranged on the top of the crawler vehicle 1, a slide rail frame 3 is arranged on the top of the turning platform 2, a drive motor 4 is arranged on the slide rail frame 3, and also includes a drilling component 5, the drilling component 5 is installed at the output end of the drive motor 4, the drilling component 5 is used for foundation drilling, a fixing component 6, the fixing component 6 is installed at the bottom of the drilling component 5, the fixing component 6 is used for drilling positioning, a collecting component 7, the collecting component 7 is installed on the fixing component 6, the collecting component 7 is used to collect soil blocks generated by drilling to a place away from the foundation hole position, and a dustproof component 8, the dustproof component 8 is installed on one side of the collecting component 7, and the dustproof component 8 is used to prevent dust from the soil blocks generated by drilling by spraying water through atomization.

[0027] like Figures 1 to 4As shown, the drilling assembly 5 includes a rotating disk 51, which is installed at the output end of the driving motor 4. A plurality of telescopic rods 52 are arranged at equal angles at the bottom of the rotating disk 51. A clamp 53 is connected to the bottom of the rotating disk 51. A drill bit 54 is connected to the end of the clamp 53. A shaft sleeve 55 is connected between the bottoms of the plurality of telescopic rods 52. A positioning ring 56 is connected to the bottom of the shaft sleeve 55. The shaft sleeve 55 rotates at the top of the positioning ring 56. By setting the drilling assembly 5, the operator moves the crawler 1 to the specified position, and turns the turning table 2 over through the control module (not marked in the figure), and the slide rail frame 3 is perpendicular to the hole to be drilled. The plane is driven by the control module (not marked in the figure) to drive the slide rail frame 3 to move the driving motor 4 in the vertical downward direction, so that the rotating disk 51 moves downward with the driving motor 4, and the shaft sleeve 55 and the positioning ring 56 connected to the rotating disk 51 through the telescopic rod 52 move downward, thereby driving the drill bit 54 to move toward the direction of the drilled ground. During the drilling operation, the driving motor 4 drives the rotating disk 51 and the drill bit 54 to rotate, and the rotating disk 51 drives the shaft sleeve 55 to rotate through the connection of the telescopic rod 52. The telescopic rod 52 can block the drill bit 54 inside to prevent the drill bit 54 from idling and jumping, causing injury to the operator.

[0028] like Figure 1 , Figure 2 and Figure 5As shown, the fixing assembly 6 includes a connecting frame 61, which is arranged at an equal angle at the bottom end of the positioning ring 56, and the connecting frame 61 is provided with four groups. The bottom end of each group of connecting frames 61 is connected to a fixing arm 62, and the outer side of each group of connecting frames 61 is symmetrically connected to two support arm seats 63, and the inner side of each support arm seat 63 is connected to an auxiliary support arm 64 through a pin shaft, and the tail end of the auxiliary support arm 64 is connected to a mounting frame 65 through a pin shaft, and the mounting frame 65 rotates at the tail end of the auxiliary support arm 64, and one end of the mounting frame 65 is connected to an anti-skid plate 66, and the anti-skid plate 66 rotates at one end of the mounting frame 65, and the inner side of the mounting frame 65 is connected to a roller 67, and the roller 67 rotates on the inner side of the mounting frame 65; by setting the fixing assembly 6, the shaft sleeve 55 and the positioning ring 56 connected to the rotating disk 51 through the telescopic rod 52 move downward, and the fixing arm 62 is inserted into the ground through the toothed structure at the bottom, which is used for positioning and fixing before drilling. In the process, the roller 67 rolls on the ground, and the auxiliary support arm 64 flips on the inner side of the support arm seat 63. When the fixed arm 62 is inserted into the ground for more than half, the roller 67 is affected by the weight of the auxiliary support arm 64 and the blocking force of the ground, so that the auxiliary support arm 64 is unfolded and drives the mounting frame 65 to rotate at the end of the auxiliary support arm 64, so that the anti-slide plate 66 contacts the ground by flipping. When the fixed arm 62 is fully inserted into the ground, the force arm of the fixed arm 62 and the auxiliary support arm 64 forms a vertical state, and the anti-slide plate 66 is close to the ground to prevent the auxiliary support arm 64 from slipping on the ground, thereby improving stability, so that the structure can position the foundation drilling hole while providing sufficient support force for the drill bit 54 in the drilling hole to prevent the drill bit 54 from hitting a harder geological structure. Since the driving force application point of the drill bit 54 is too high, the drill bit 54 is tilted during the drilling operation, resulting in construction errors and reducing the possibility of excessive wear and breakage of the drill bit 54.

[0029] like Figure 6 , Figures 8 to 10As shown, the collecting assembly 7 includes a rotating shaft 71, which is sleeved on the outside of the sleeve 55. A guide groove 72 is provided on the surface of the rotating shaft 71. A mounting box 73 is sleeved on the outside of the rotating shaft 71. The mounting box 73 is mounted on the top of the positioning ring 56 by bolts. A dust cover 730 is provided on the outside of the mounting box 73. The dust cover 730 is located on the outside of the sleeve 55. The rotating shaft 71 rotates on the inside of the mounting box 73. Two groups of sliding grooves 74 are symmetrically provided on the inside of the mounting box 73. A connecting plate 75 is installed on the inside of each group of sliding grooves 74. The connecting plate 75 slides on the inside of the sliding groove 74. One side of the connecting plate 75 is connected to A guide rod 76, the guide rod 76 slides on the inner side of the guide groove 72, a spring 77 is sleeved on the outer side of the guide rod 76, the tail end of the spring 77 is connected to the end of the connecting plate 75, two groups of scrapers 78 are symmetrically connected to the outer wall of the rotating shaft 71, the scrapers 78 are set to be arc-shaped, the scrapers 78 are made of polycarbonate plastic material, the bottom end of the scrapers 78 is connected to a shovel plate 780, the cross section of the shovel plate 780 is set to be a right-angled trapezoid, the end of the shovel plate 780 is connected to an anti-skid wheel 781, the anti-skid wheel 781 is made of rubber material, and the surface of the anti-skid wheel 781 is provided with an anti-skid edge block, and two collecting ports 79 are symmetrically provided on the outer side of the dust cover 730; By setting the collecting assembly 7, during the drilling operation of the drill bit 54, the sand and soil produced by the drilling will be sprinkled out from the inner side of the sleeve 55 along the spiral blade surface of the drill bit 54, and the dust cover 730 can effectively avoid the smoke and dust produced by the splashing of sand and soil, and at the same time, reduce the safety impact of the splashing of stones in the sand and soil on the surrounding operators. The sand and stones are accumulated on the top of the installation box 73, and the rotating disk 51 drives the sleeve 55 to rotate through the connection of the telescopic rod 52, and the rotating shaft 71 rotates with the sleeve 55, and the guide rod 76 slides on the inner side of the N-shaped guide groove 72. The deformation pressure generated by the spring 77 makes the guide rod 76 always on the inner side of the guide groove 72 and will not be separated from the inner side of the guide groove 72. The guide rod 76 drives the connecting plate 75 connected to the tail end to slide on the inner side of the sliding groove 74, and the rotating shaft 71 drives the two groups of outer The scraper 78 scrapes and collects the sand and soil generated by the drilling at the top of the installation box 73. Since the shovel plate 780 is set to a right-angled trapezoid and has an inclined blade surface, the shovel plate 780 at the bottom of the scraper plate 78 can scrape out wet mud and silt to the outside. The anti-skid wheel 781 assists in rolling on one side of the shovel plate 780, providing sufficient friction for the shovel plate 780 and the scraper plate 78 to avoid slipping during scraping and collection. The sand and soil products are discharged from the collection port 79 of the dust cover 730. The operator can collect the sand and soil by connecting a sand collection bag to the collection port 79, which can efficiently collect the drilling chips without causing harm to the personal safety of the operator. At the same time, it avoids the accumulation of a large amount of sand and gravel chips at the pile hole mouth, causing the foundation pile hole to collapse, and avoids the drill bit 54 from being stuck due to untimely chip removal during drilling, thereby improving work efficiency.

[0030] like Figures 10 to 13 As shown, the dustproof component 8 includes a sleeve 81, which is installed on one side of the connecting plate 75, and the sleeve 81 slides on the inner side of the installation box 73. The inner side of the sleeve 81 is connected with an elastic telescopic rod 82, and the tail end of the elastic telescopic rod 82 is connected to the inner wall of the installation box 73. The top of the sleeve 81 is connected with an atomizing nozzle 83, and the outer side of the sleeve 81 is connected with a synchronous frame 84. The inner side of the synchronous frame 84 is nested with a piston rod 85, and the piston rod 85 passes through the top of the water tank 87. The end of the piston rod 85 is connected with a piston 86, and the outer side of the piston 86 is sleeved with a water tank 87. The piston 86 slides on the inner side of the water tank 87, and the water tank 87 is symmetrically installed on the outer side of the installation box 73. A one-way valve 88 is connected to one side of the water tank 87, and the one-way valve 88 is connected to the atomizing nozzle 83 through a pipeline. A filling port 870 is connected to one side of the water tank 87. By setting the dustproof component 8, the rotating disk 51 drives the shaft sleeve 55 to rotate through the connection of the telescopic rod 52, and the rotating shaft 71 rotates along the shaft sleeve 55. The rotation of the rotating shaft 71 causes the guide rod 76 to slide along the guide groove 72. The deformation pressure generated by the spring 77 makes the guide rod 76 always close to the inner side of the guide groove 72 and will not separate from the inner side of the guide groove 72. Since the rotating shaft 71 continues to rotate, when the guide rod 76 reaches the lowest point of the N-shaped guide groove 72, the guide rod 76 in the vertical direction is no longer squeezed by the vertical direction of the guide groove 72, so that the elastic telescopic rod 82 pushes the sleeve 81 to overcome gravity and move upward The guide rod 76 moves from the highest point of the N-shaped guide groove 72 to the lowest point of the N-shaped guide groove 72, and the guide rod 76 moves from the highest point of the N-shaped guide groove 72 to the lowest point of the N-shaped guide groove 72. During this process, the guide rod 76 drives the connecting plate 75 connected to the tail end to slide downward on the inner side of the sliding groove 74, thereby driving the sleeve 81 to move vertically downward on the inner side of the installation box 73. The elastic telescopic rod 82 connected to the inner bottom end of the sleeve 81 is compressed by force, and the sleeve 81 performs two vertical reciprocating motions on the inner side of the installation box 73. When the sleeve 81 moves, the piston rod 85 and the sleeve 81 can move at the same speed through the connection of the synchronous frame 84 on the corresponding side. When the piston rod 85 moves downward, the piston 86 slides downward inside the water tank 87, so that the piston 86 is located below the filling port 870 of the water tank 87. The external water pipe transports water from the filling port 870 to the top of the piston 86. The piston 86 moves upward, so that the water is squeezed in the chamber above the piston 86, and the water enters the one-way valve 88 and enters the inside of the atomizing nozzle 83 through the pipeline. The water is atomized and sprayed inside the dust cover 730. When the sleeve 81 moves downward, the piston rod 85 is driven downward by the connection of the synchronous frame 84 to push the piston 86. Through the up and down movement of the sleeve 81, the atomized water can be sprayed at different heights to increase the air humidity in the dust cover 730, reduce the amount of dust floating in the air, avoid pollution to the surrounding environment during construction, and at the same time, reduce the impact on the health of operators during construction.

[0031] The working principle of the technical solution provided by the present invention is as follows: The operator moves the crawler vehicle 1 to the specified position, and turns the turning table 2 through the control module (not marked in the figure), and the slide rail frame 3 is perpendicular to the plane to be drilled. The control module (not marked in the figure) is used to drive the drive motor 4 to move in the vertical downward direction, so that the rotating disk 51 moves downward with the drive motor 4, and the sleeve 55 and the positioning ring 56 connected to the rotating disk 51 through the telescopic rod 52 move downward, thereby driving the drill bit 54 to move toward the direction of the drilling ground. During the drilling operation, the drive motor 4 drives the rotating disk 51 and the drill bit 54 to rotate, and the rotating disk 51 drives the sleeve 55 to rotate through the connection of the telescopic rod 52.

[0032] The shaft sleeve 55 and the positioning ring 56 connected to the rotating disk 51 through the telescopic rod 52 move downward, and the fixed arm 62 is inserted into the ground through the toothed structure at the bottom for positioning and fixing before drilling. During the downward movement of the fixed arm 62, the roller 67 rolls on the ground, and the auxiliary support arm 64 turns over on the inner side of the support arm seat 63. When the fixed arm 62 is inserted into the ground more than half, the roller 67 is affected by the weight of the auxiliary support arm 64 and the barrier force of the ground, so that when the auxiliary support arm 64 is unfolded, it drives the mounting frame 65 to rotate at the end of the auxiliary support arm 64, so that the anti-slip The plate 66 contacts the ground by flipping, and when the fixed arm 62 is fully inserted into the ground, the force arm of the fixed arm 62 and the auxiliary support arm 64 forms a vertical state. At the same time, the anti-slip plate 66 is close to the ground to prevent the auxiliary support arm 64 from slipping on the ground, thereby improving stability. While the structure is positioning the foundation drilling hole, it provides sufficient support force for the drill bit 54 in the drilling hole to prevent the drill bit 54 from hitting a harder geological structure. Since the driving force point of the drill bit 54 is too high, the drill bit 54 will tilt during the drilling operation, resulting in construction errors and reducing the possibility of excessive wear and breakage of the drill bit 54.

[0033] When the drill bit 54 is drilling, the sand and soil generated by drilling will be scattered from the inner side of the sleeve 55 along the spiral blade surface of the drill bit 54. The dust cover 730 can effectively prevent the smoke and dust generated by the splashing of sand and soil. At the same time, it reduces the safety impact of the splashing of stones in the sand and soil on the surrounding operators. The sand and stones are accumulated on the top of the installation box 73. The rotating disk 51 drives the sleeve 55 to rotate through the connection of the telescopic rod 52. The rotating shaft 71 rotates with the sleeve 55. The guide rod 76 slides on the inner side of the N-shaped guide groove 72. The deformation pressure generated by the spring 77 ensures that the guide rod 76 is always on the inner side of the guide groove 72 and will not be separated from the inner side of the guide groove 72. The guide rod 76 drives the connecting plate 75 connected to the tail end to slide on the inner side of the sliding groove 74. The rotating shaft 71 drives the two sets of scrapers 78 on the outer side during rotation. The sand and soil generated by the drilling at the top of the installation box 73 is scraped and collected. Since the shovel plate 780 is set to a right-angle trapezoid and has an inclined blade surface, the shovel plate 780 at the bottom of the scraper plate 78 can scrape out wet mud and silt to the outside. The anti-skid wheel 781 assists in rolling on one side of the shovel plate 780 to provide sufficient friction for the shovel plate 780 and the scraper plate 78 to avoid slipping during scraping and collection. The sand and soil products are discharged from the collection port 79 of the dust cover 730. The operator can collect the sand and soil by connecting a sand collection bag to the collection port 79, which can efficiently collect the drilling chips without causing harm to the personal safety of the operator. At the same time, it avoids the accumulation of a large amount of sand and gravel chips at the pile hole mouth, which causes the collapse of the foundation pile hole, and avoids the jamming of the drill bit 54 due to untimely chip removal during drilling, thereby improving work efficiency.

[0034] The rotating disk 51 drives the shaft sleeve 55 to rotate through the connection of the telescopic rod 52, and the rotating shaft 71 rotates along the shaft sleeve 55. The rotation of the rotating shaft 71 causes the guide rod 76 to slide along the guide groove 72. The deformation pressure generated by the spring 77 keeps the guide rod 76 always close to the inner side of the guide groove 72 and will not separate from the inner side of the guide groove 72. As the rotating shaft 71 continues to rotate, when the guide rod 76 reaches the lowest point of the N-shaped guide groove 72, the guide rod 76 in the vertical direction is no longer squeezed by the vertical direction of the guide groove 72, so that the elastic telescopic rod 82 pushes the sleeve 81 to overcome gravity and move upward. The connecting plate 75 moves upward on the inner side of the sliding groove 74, thereby driving the guide rod 76 to reach the highest point of the N-shaped guide groove 72, so that the rotating shaft 71 rotates one circle, and the guide rod 76 moves from the highest point of the N-shaped guide groove 72 along the arc portion to the lowest point of the N-shaped guide groove 72. During this process, the guide rod 76 drives the connecting plate 75 connected to the tail end to slide downward on the inner side of the sliding groove 74, thereby driving the sleeve 81 to move vertically downward on the inner side of the installation box 73. The elastic telescopic rod 82 connected to the bottom end of the inner side of the sleeve 81 is compressed by force, and the sleeve 81 performs two vertical reciprocating movements on the inner side of the installation box 73. The sleeve 81 is connected to the synchronous frame 84 on the corresponding side during movement, so that the piston rod 85 and the sleeve 81 can move at the same speed. When the piston rod 85 is moving downward, the piston 86 slides downward inside the water tank 87, so that the piston 86 is located below the filling port 870 of the water tank 87 (because the one-way valve 88 can only flow in one direction from the water tank 87 to the atomizing nozzle 83). At this time, the water pressure of the external water pipe is gradually transported from the filling port 870 to the top of the piston 86, and gradually fills the upper part of the water tank 87. When the piston rod 85 is moving upward, it drives the piston 86 The piston 86 moves upward, squeezing the water in the chamber above the piston 86, so that the water enters the pipeline through the one-way valve 88 and enters the atomizing nozzle 83. The water is atomized by the atomizing nozzle 83 and sprayed on the inside of the dust cover 730. When the sleeve 81 moves downward, the piston rod 85 is driven downward by the connection of the synchronous frame 84 to push the piston 86. The up and down movement of the sleeve 81 allows the atomized water to be sprayed at different heights to increase the air humidity in the dust cover 730, reduce the amount of dust floating in the air, avoid pollution to the surrounding environment during construction, and at the same time, reduce the impact on the health of operators during construction.
