Description

Technical Field

[0001] The invention relates to the technical field of pile drivers, in particular to a pile driver used in construction engineering. Background Art

[0002] There are many types of pile drivers, including spiral pile drivers. A spiral pile driver is a type of pile driving equipment that uses a power head to drive a drill rod and drill bit to drill holes underground. During construction, the spiral pile driver is moved to the construction site and fixed with outriggers to control the drilling of the drill bit. After the excavation and slag removal meet the requirements, the drill bit is retracted and the steel cage is lowered, followed by concrete pouring. In some cases, it is necessary to use the accumulated slag for partial backfill.

[0003] During the drilling process of the spiral drill bit, the spiral blades on the drill bit will bring out the soil. The spiral blades are in a rotating state, and the soil on the spiral blades will be thrown out to the surroundings due to the centrifugal force. However, if the soil is wet, the soil will adhere to the blades and be difficult to clean; and the thrown soil will accumulate around the drill hole. When the pile driver moves to the next position to drill a hole, the accumulated soil is easy to fall into the drill hole, thereby affecting the hole depth and being unfavorable for the placement of the steel cage. In addition, when the spiral pile driver drills a hole in the concrete floor, it is easy to produce dust due to the loose and dry characteristics of the crushed thick concrete, which will affect the workers' sight. Therefore, the present application provides a pile driver for construction engineering to meet the needs. Summary of the invention

[0044] like Figures 1 to 17 As shown, an embodiment of the present invention provides a pile driver for construction engineering. The pile driver for construction engineering of this embodiment includes a main body 1, a frame 2 is arranged on the main body 1, a drill rod and a driving mechanism for driving the drill rod are arranged on the frame 2, and the above mechanisms are all prior arts and will not be described in detail here; it also includes a processing component for processing soil on the drill rod and accumulated near the drill hole, and the processing component is installed on the frame 2.

[0045] like Figures 1 to 8 As shown, the processing assembly includes a steering assembly 25 and a protective tube 17 fixedly connected to the frame 2. A pair of discharge hoppers 4 are fixedly connected to the steering assembly 25. The pair of discharge hoppers 4 are relatively arranged with the protective tube 17 as the center, wherein the center of the discharge hopper 4 is an arc structure. When the drill rod is drilling a hole, the protective tube 17 is pressed on the ground, and the soil is sent to the top of the borehole along with the drill rod. Since the protective tube 17 is pressed on the ground, the taken out soil is transported outward through the protective tube 17 and falls on the discharge hoppers 4 at both ends of the protective tube 17. At the same time, the soil on the drill rod is centrifuged. The soil is thrown out to the surroundings by the action of force. At this time, the thrown soil falls on the discharge hopper 4 at both ends of the protective tube 17. The discharge hopper 4 rotates under the influence of the gravity of the soil, so that the soil on the discharge hopper 4 is discharged to the two ends of the protective tube 17, thereby preventing the thrown soil from accumulating around the drill hole. When the pile driver moves to the next position to drill a hole, the accumulated soil is easy to fall into the drill hole and affect the hole depth. The fixed shell 3 and the discharge hopper 4 are both fixed to the frame 2, and the discharge hopper 4 is located below the fixed shell 3, and the drill rod passes through the fixed shell 3 and the discharge hopper 4 in sequence.

[0046] like Figures 3 to 14As shown, the steering assembly 25 is rotatably connected with a first fixed rod 26 and a second fixed rod 27, and the inner ends of the first fixed rod 26 and the second fixed rod 27 are fixedly connected with a gear 28, and the first fixed rod 26 and the second fixed rod 27 are meshed and transmitted by two gears 28, and the outer ends of the first fixed rod 26 and the second fixed rod 27 are respectively fixed to a pair of discharge hoppers 4. Since the inner ends of the first fixed rod 26 and the second fixed rod 27 are meshed and transmitted by two gears 28, the angles of the outer ends of the first fixed rod 26 and the second fixed rod 27 are different, and the pair of discharge hoppers 4 are respectively fixedly connected to the first fixed rod 26 and the second fixed rod 27. When one of the discharge hoppers 4 tilts and rotates, the other discharge hopper 4 is driven to tilt and rotate through the transmission of the gear 28. Since the angles of the outer ends of the first fixed rod 26 and the second fixed rod 27 are different, the pair of discharge hoppers 4 can be linked and tilted alternately to prevent the problem of soil accumulation on one of the discharge hoppers 4, resulting in the inability to discharge.

[0047] like Figures 10 to 17 As shown, a pair of the discharge hoppers 4 are fixedly connected with a half ring 20, a pair of the half rings 20 are rotatably connected with a plurality of connecting strips 18, a tightening ring 21 is rotatably connected to one end of the plurality of connecting strips 18 away from the half ring 20, and the tightening ring 21 is fixedly connected with a plurality of buckle plates 29; the tightening ring 21 is clamped and fixed to the protective tube 17 by a plurality of buckle plates 29, the tightening ring 21 includes a plurality of hollow arc rods 23, both ends of the plurality of hollow arc rods 23 are limitedly slidably provided with sliding arc rods 24, the plurality of hollow arc rods 23 are slidably connected by a plurality of sliding arc rods 24, and the connecting strips 18 of a plurality of elastic structures can drive the tightening ring 21 to contract; wherein, the plurality of connecting strips 18 are elastic Structure, one end of the multiple connecting strips 18 is fixed to the top of the protective tube 17 through the tightening ring 21 and the buckle plate 29, the other end of the multiple connecting strips 18 is fixed to the half ring 20 fixed on the discharge hopper 4, the tightening ring 21 is installed in the state: the protective tube 17 is located between the tightening ring 21 and the buckle plate 29, the function of the multiple connecting strips 18 is: when one of the discharge hoppers 4 is tilted, the downward tilted end will drive the connecting strip 18 to stretch, after the soil on the discharge hopper 4 is unloaded, the connecting strip 18 in the stretched state can drive the discharge hopper 4 to reset. It should be noted that the number of elastic structure connecting strips 18 can be increased or decreased according to the actual operating conditions to adjust the stretching and reset capabilities.

[0048] like Figures 9 to 11As shown, the surfaces of the semi-ring 20, the tightening ring 21 and the connecting strip 18 are wrapped with a protective sleeve 19. The protective sleeve 19 is made of a film, cloth or other material in the prior art. The protective sleeve 19 is sleeved on the surfaces of the semi-ring 20, the tightening ring 21 and multiple connecting strips 18. The advantage of such a configuration is that when the tightening ring 21 is fixed between the protective tube 17 and the discharge hopper 4, the connecting strip 18 is in an inclined state. At this time, the protective sleeve 19 on the surface of the connecting strip 18 can play an isolation role to prevent soil from affecting the operation of the connecting strip 18, and the soil brought out by the drill rod can fall onto the discharge hopper 4 through the inclined protective sleeve 19; in addition, when the connecting strip 18 is stretched or reset, the protective sleeve 19 can be driven to move, which further facilitates the soil on the surface of the protective sleeve 19 to fall into the discharge hopper 4.

[0049] like Figures 6 to 8 As shown, the frame 2 is also fixedly connected with a fixed shell 3, the top of the fixed shell 3 is bent inwardly to form an inner tube 5, and the bottom of the fixed shell 3 is bent inwardly to form a lower plate 7, and an empty area 22 is formed between the inner tube 5 and the lower plate 7, and an annular groove 6 is provided at one end of the empty area 22, and a plurality of drainage holes 8 are provided at the other end of the empty area 22. During the cleaning process, the sewage entering the empty area 22 can be discharged through the drainage holes 8; a fixing ring 9 is clamped and fixed on the fixed shell 3, and a plurality of fixing plates 10 are fixedly connected to the bottom end of the fixing ring 9. The plurality of fixing plates 10 are arranged in an annular array with the fixing ring 9 as the center, and the plurality of fixing plates 10 surround the drill rod; during installation, the plurality of fixing plates 10 are inserted into the fixed shell 3, and the fixing ring 9 at the top of the fixing plate 10 is clamped at the top of the fixed shell 3, and the plurality of fixing plates 10 are fixed by the limit of the fixed shell 3, and at the same time, the inclined plate 13 at the bottom end of the fixing plate 10 is inserted into the annular groove 6, which has the effect of reinforcing the installation, thereby facilitating assembly and maintenance.

[0050] like Figures 3 to 9As shown, a plurality of the fixing plates 10 are all installed with a brush plate 11 and a high-pressure nozzle 12, and a plurality of the brush plates 11 and a plurality of the high-pressure nozzles 12 are arranged in a surrounding manner. The high-pressure nozzle 12 is connected to an external high-pressure pump, a water storage tank and other devices. The structures such as the high-pressure pump and the water storage tank are all existing technologies and can be installed on the main body 1. The control method is the existing manual control or remote control. No further details will be given here. An inclined plate 13 is fixedly connected to one end of the fixing plate 10 away from the fixing ring 9. The bottom end of the inclined plate 13 is bent outward to form a hook 15. The hook 15 is adapted to the size of the first fixing rod 26 or the second fixing rod 27 in the tightening ring 21. After the operation is completed, the drill rod is operated to rise, and the tightening ring 21 is first taken out from the top of the protective tube 17, and then the tightening ring 21 is pulled outward, and then the tightening ring 21 is buckled on the hook 15. The fixed plate 10 is stretched downward by the traction of the connecting strip 18, so that the inclined fixed plate 10 is in a vertical state, and the brush plate 11 on the fixed plate 10 in the vertical state can contact the drill pipe, and then the high-pressure nozzle 12 is started, and multiple surrounding high-pressure nozzles 12 surround the peripheral surface of the drill pipe for flushing, and multiple surrounding brush plates 11 brush the peripheral surface of the drill pipe, and the brush plates 11 and the high-pressure nozzles 12 are alternately arranged, and the effects of alternating flushing and brushing are achieved during the rising process of the drill pipe, thereby improving the cleaning effect; since the top of the connecting strip 18 is connected to the fixed plate 10, the protective cover 19 on the surface of the connecting strip 18 surrounds the fixed shell 3 and the discharge hopper 4 at this time, so during the cleaning process, the protective cover 19 can also play a role in isolating water mist, reducing the problem of water mist affecting the work of the staff.

[0051] like Figures 3 to 15 As shown, the center of the inclined plate 13 is sunken inward to form a sunken portion 16, and the edge of the sunken portion 16 is an arc-shaped structure. When the multiple high-pressure nozzles 12 arranged around spray water to the drill rod in the center, a part of the water flow will fall on the inclined plate 13. Since the surface of the inclined plate 13 at the bottom end of the fixed plate 10 is provided with a sunken portion 16, the water flow that falls straight into the sunken portion 16 slides outward along the edge of the arc surface structure, thereby improving the utilization rate of the water flow. If there is a lot of mud on the drill rod, the high-pressure nozzle 12 can be directly started to flush the drill rod first, and then the fixed plate 10 and the connecting strip 18 are connected, and then The purpose of secondary flushing and brushing is to reduce the cleaning pressure of the brush plate 11, and the cleaning method can be adjusted according to needs; in addition, when the fixing plate 10 and the connecting strip 18 are not connected, the brush plate 11 is not in contact with the drill rod, and there will be no concrete adhesion on the drill rod. This state is suitable for drilling work on hard ground such as concrete. During operation, the water sprayed by the high-pressure nozzle 12 is sprayed on the drill rod, which can moisten the drill rod, reduce drill bit wear and reduce dust floating, and the water on the drill rod flows into the drill hole along the drill rod to moisten the drill hole position in advance, which is beneficial to the drilling work.

[0052] like Figures 3 to 5As shown, a bending portion 14 is formed between the fixed plate 10 and the inclined plate 13, and the bending portion 14 and the multiple fixed plates 10 are all made of elastic material, wherein the bending portion 14 is a C-type elastic structure. The advantage of such a configuration is that the C-type elastic structure is located between the fixed plate 10 and the inclined plate 13, which can provide a fault-tolerant position between the fixed plate 10 and the inclined plate 13 to prevent the fixed plate 10 from being twisted and damaged when it is subjected to a large traction effect; in addition, when the brush plate 11 on the fixed plate 10 is in the process of cleaning the drill rod, the spiral blades on the drill rod may be squeezed with the bristles on the brush plate 11, and the setting of the bending portion 14 can buffer the squeezing of the brush plate 11, thereby facilitating the cleaning operation.

[0053] The working principle of the technical solution provided by the present invention is as follows: when the drill rod is drilling a hole, the protective tube 17 is pressed against the ground, and the soil is sent to the top of the borehole along with the drill rod. Since the protective tube 17 is pressed against the ground, the taken out soil is transported outward through the protective tube 17 and falls on the discharge hopper 4 at both ends of the protective tube 17. At the same time, the soil on the drill rod is thrown out to the surroundings due to the action of centrifugal force. At this time, the thrown out soil falls on the discharge hopper 4 at both ends of the protective tube 17. The discharge hopper 4 rotates under the influence of the gravity of the soil, so that the soil on the discharge hopper 4 is discharged to the two ends of the protective tube 17, thereby preventing the thrown out soil from accumulating around the borehole. When the pile driver moves to the next position to drill a hole, the accumulated soil is easy to fall into the borehole and affect the hole depth.

[0054] Since the inner ends of the first fixed rod 26 and the second fixed rod 27 are meshed and transmitted through two gears 28, the angles of the outer ends of the first fixed rod 26 and the second fixed rod 27 are different, and a pair of discharge hoppers 4 are respectively fixedly connected to the first fixed rod 26 and the second fixed rod 27. When one of the discharge hoppers 4 tilts and rotates, the other discharge hopper 4 is driven to tilt and rotate through the transmission of the gear 28. Since the angles of the outer ends of the first fixed rod 26 and the second fixed rod 27 are different, the pair of discharge hoppers 4 can be linked and tilted alternately to prevent the problem of soil accumulation on one of the discharge hoppers 4, resulting in the inability to discharge.

[0055] After the operation is completed, the drill rod is raised. First, the tightening ring 21 is taken out from the top of the protective tube 17, and then the tightening ring 21 is pulled outward, and then the tightening ring 21 is buckled on the hook 15. The fixing plate 10 is pulled downward by the traction of the connecting strip 18, so that the inclined fixing plate 10 is in a vertical state, and the brush plate 11 on the fixing plate 10 in the vertical state can contact the drill rod, and then the high-pressure nozzle 12 is started. A plurality of surrounding high-pressure nozzles 12 surround the peripheral surface of the drill rod for flushing, and a plurality of surrounding brush plates 11 brush the peripheral surface of the drill rod. The brush plates 11 and the high-pressure nozzles 12 are alternately arranged, and the effects of alternating flushing and brushing are achieved during the rising process of the drill rod, thereby improving the cleaning effect; since the top of the connecting strip 18 is connected to the fixing plate 10, at this time, the protective cover 19 on the surface of the connecting strip 18 surrounds the fixing shell 3 and the discharge hopper 4, so during the cleaning process, the protective cover 19 can also play a role in isolating water mist, reducing the problem of water mist affecting the operation of the staff.

[0056] When drilling a hole in the concrete floor, the connecting strip 18 and the top end of the protective tube 17 are fixed, and the fixing plate 10 is not pulled, so that the brush plate 11 does not contact the drill rod. The water sprayed by the high-pressure nozzle 12 is sprayed on the drill rod, which can moisten the drill rod, reduce drill bit wear and reduce dust floating, and the water on the drill rod flows into the drill hole along the drill rod to moisten the drill hole position in advance, which is beneficial to the drilling work.

[0057] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0058] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

The discharge hopper rotates under the influence of the gravity of the soil, so that the soil on the discharge hopper is discharged to the two ends of the protective tube, thereby preventing the thrown soil from accumulating around the borehole; Since the inner ends of the first fixed rod and the second fixed rod are meshed with each other through two gears, the angles of the outer ends of the first fixed rod and the second fixed rod are different, and a pair of discharge hoppers are respectively fixedly connected to the first fixed rod and the second fixed rod, when one of the discharge hoppers is tilted and rotated, the other discharge hopper is driven to tilt and rotate through the action of the gear transmission. Since the angles of the outer ends of the first fixed rod and the second fixed rod are different, the pair of discharge hoppers can realize linkage and alternating tilting; A pair of the discharge hoppers are fixedly connected with a half ring, and a pair of the half rings are rotatably connected with a plurality of connecting strips, and a tightening ring is rotatably connected to one end of the plurality of connecting strips away from the half rings, and a plurality of buckle plates are fixedly connected to the tightening ring. When one of the discharge hoppers is tilted, the downwardly tilted end will drive the connecting strip to stretch. After the soil on the discharge hopper is unloaded, the connecting strip in a stretched state can drive the discharge hopper to reset. The tightening ring is fixed on the protective tube by clamping multiple gusset plates, and the tightening ring includes multiple hollow arc rods, both ends of the multiple hollow arc rods are limitedly slid with sliding arc rods, and the multiple hollow arc rods are connected by multiple sliding arc rods; The surfaces of the half ring, the tightening ring and the connecting strip are wrapped with protective sleeves, and the connecting strips with multiple elastic structures can drive the tightening ring to contract. When the tightening ring is fixed between the protective tube and the discharge hopper, the connecting strip is in an inclined state. At this time, the protective sleeve on the surface of the connecting strip can play an isolation role to prevent soil from affecting the operation of the connecting strip, and the soil brought out by the drill rod can fall onto the discharge hopper through the inclined protective sleeve.
