Description

Technical Field

[0001] This utility model relates to the field of photovoltaic grouting pile technology, specifically a deep hole drilling device for photovoltaic grouting piles. Background Technology

[0002] To support and reinforce photovoltaic panels, most manufacturers choose to drill holes in the land at the installation site and install wooden or metal piles. First, the device is moved to the piling site, holes are drilled and excess soil is removed, then liquid is injected to compact the sidewalls, the drilling mechanism is further settled to compact the holes, and then the pile body is inserted and cement is poured in to seal it.

[0003] In most cases, the pilot hole operation is separate from the injection mechanism. The pilot hole device needs to be removed before the injection device can be pushed forward. The back-and-forth switching is not only labor-intensive, but also inconvenient to save time and energy. It is difficult to integrate the pilot hole and injection into one unit, and the liquid is not very convenient to carry.

[0004] Now, a novel deep-hole drilling device for photovoltaic cast-in-place piles is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a deep hole drilling device for photovoltaic cast-in-place piles to solve the problem of lack of linkage capability mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep hole drilling device for photovoltaic cast-in-place piles, comprising a base, a rotating platform movably connected to the left side of the top of the base, and a spiral groove provided on the left side inside the rotating platform; an L-shaped frame fixed to the left side of the top of the rotating platform, and a motor fixed to the top of the L-shaped frame; a lead screw movably connected to the bottom of the top of the L-shaped frame, and a spiral drill bit wrapped around the outside of the lead screw; a threaded chamber longitudinally provided inside the spiral drill bit; a through groove provided on the left side inside the base; and casters installed at the four corners below the base.

[0007] As a further technical solution of this utility model, a water storage tank is fixed on the right side of the top of the base, and a suction tube is fixed on the left side of the top of the water storage tank. A flexible tube is fixed on the left side of the top of the water storage tank. A frame is fixed on the left side of the outside of the water storage tank. An injection head is fixed on the right side of the bottom of the rotating platform. A liquid pump is fixed on the right side of the top of the rotating platform.

[0008] As a further technical solution of this utility model, the inner wall of the spiral groove matches the spiral drill, the lead screw is embedded in the threaded cavity, and the bottom of the output end of the motor is fixedly connected to the lead screw.

[0009] As a further technical solution of this utility model, the bottom of the hose is connected to the liquid pump and the injection head, and the top of the hose is connected to the suction tube.

[0010] As a further technical solution of this utility model, a bracket is fixed on the left side of the center of the bottom of the base, and a worm gear is movably connected between the front and rear of the bracket. A second motor is fixed at the rear of the outside of the bracket. A worm wheel is meshed on the left side of the worm gear, and the top of the worm wheel passes through the base and is fixedly connected to the rotary table. The front of the output end of the second motor is fixedly connected to the worm gear.

[0011] As a further technical solution of this utility model, a sleeve block is fixed on the left side of the bottom of the base, and a rotating rod is movably connected in the sleeve block. A baffle is fixed at the bottom of the rotating rod, and a bolt is threadedly connected to the front end of the sleeve block.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the photovoltaic grouting pile deep hole pilot hole device not only realizes the unified pilot hole and grouting functions and facilitates the replacement of the mechanism, but also prevents the drill rod from rubbing against the ground;

[0013] (1) By wrapping the screw with a spiral drill bit, the base is moved to the pilot hole position by the caster and the motor is started to rotate the screw bit. Since the spiral drill bit is embedded in the spiral groove, the spiral drill bit with the threaded chamber can be spirally raised and lowered as the screw bit rotates, forcing the spiral drill bit to pass through the through groove on the left side of the base and drill into the ground. As the spiral drill bit rises, more soil is extracted. After cleaning, the rotary table is rotated and the injection head on the right side is moved to the top of the hole. The liquid pump is turned on and the clear liquid is drawn out and injected into the hole through the hose and suction pipe. After the infiltration is completed, the pilot hole operation is carried out again to compact the surrounding soil.

[0014] (2) A rotating table is movably connected to the left side of the top of the base. The top of the worm gear is movably installed under the base. The worm is rotated by turning on the second motor. The worm gear guides the worm wheel on the left side to rotate in place. Depending on the progress of the project, the drilling mechanism on the left side or the liquid injection mechanism on the right side can be selected. The worm gear has a locking function to prevent the rotating table from rotating and to ensure the smooth and safe operation of the work.

[0015] (3) By fixing a baffle at the bottom of the auger, after the second hole-reaming operation of the auger is completed, the object is raised a certain distance, and then the auger is rotated horizontally in the sleeve block to guide the baffle fixed at the bottom to support the bottom of the auger, so as to prevent the bottom of the auger from contacting the ground and causing wear when the base and the whole device are moved by the casters, and to keep the auger away from the ground by a certain distance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides an embodiment of a photovoltaic grouting pile deep hole drilling device, including a base 1, a rotating platform 2 movably connected to the left side of the top of the base 1, and a spiral groove 24 provided inside the left side of the rotating platform 2, an L-shaped frame 3 fixed to the left side of the top of the rotating platform 2, and a motor 6 fixed to the top of the L-shaped frame 3, a lead screw 5 movably connected to the bottom of the top of the L-shaped frame 3, and a spiral drill 4 wrapped around the outside of the lead screw 5, a threaded chamber 7 longitudinally provided inside the spiral drill 4, a through groove 18 provided inside the left side of the base 1, casters 11 installed at the four corners below the base 1, the inner wall of the spiral groove 24 matching the spiral drill 4, the lead screw 5 embedded in the threaded chamber 7, and the bottom of the output end of the motor 6 fixedly connected to the lead screw 5;

[0023] A water tank 10 is fixed to the right side of the top of the base 1, and a suction tube 20 is fixed to the left side of the top of the inside of the water tank 10. A hose 9 is fixed to the left side of the top of the water tank 10. A frame 8 is fixed to the left side of the outside of the water tank 10. An injection head 13 is fixed to the right side of the bottom of the rotary table 2. A liquid pump 12 is fixed to the right side of the top of the rotary table 2. The bottom of the hose 9 is connected to the liquid pump 12 and the injection head 13, and the top of the hose 9 is connected to the suction tube 20.

[0024] Specifically, such as Figure 1 and Figure 2As shown, after moving the base 1 to the pilot hole position with the caster 11, start the motor 6 and rotate the screw 5. Since the spiral drill 4 is embedded in the spiral groove 24, as the screw 5 rotates, the spiral drill 4 with the threaded chamber 7 can be spirally raised and lowered, forcing the spiral drill 4 to pass through the through groove 18 on the left side of the base 1 and drill into the ground. As the spiral drill 4 rises, more soil is extracted. After cleaning, rotate the rotary table 2 and move the injection head 13 on the right side to the top of the hole. Turn on the liquid pump 12 and draw clean liquid through the hose 9 and the suction pipe 20 to inject into the hole.

[0025] A bracket 16 is fixed to the left side of the center of the bottom of the base 1, and a worm gear 15 is movably connected between the front and rear of the bracket 16. A motor 14 is fixed to the rear of the bracket 16. A worm wheel 17 is meshed with the left side of the worm gear 15, and the top of the worm wheel 17 passes through the base 1 and is fixedly connected to the rotary table 2. The front of the output end of the motor 14 is fixedly connected to the worm gear 15.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, the top of the worm gear 17 is movably mounted below the base 1. By turning on the motor 14, the worm 15 is rotated, and the worm gear 17 on the left side is guided to rotate in place by the worm gear 15. Depending on the progress of the project, it is possible to choose whether to use the drilling mechanism on the left or the liquid injection mechanism on the right. The worm gear 17 and worm gear 15 have a built-in locking function to prevent the rotary table 2 from continuing to rotate.

[0027] A sleeve block 21 is fixed on the left side of the bottom of the base 1, and a rotating rod 23 is movably connected in the sleeve block 21. A baffle 19 is fixed at the bottom of the rotating rod 23, and a bolt 22 is threadedly connected to the front end of the sleeve block 21.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, after the second pre-drilling operation of the spiral drill 4 is completed, the object is raised a certain distance, and then the rotating rod 23 is rotated horizontally in the sleeve block 21 to guide the baffle 19 fixed at the bottom to support the bottom of the spiral drill 4, so as to prevent the bottom of the spiral drill 4 from contacting the ground and causing wear when the base 1 and the whole device are moved by the caster 11.

[0029] Working principle: When using this utility model, firstly, the base 1 is moved to the pilot hole position using the caster 11, then the motor 6 is started and the screw 5 is rotated. Because the spiral drill 4 is embedded in the spiral groove 24, as the screw 5 rotates, the spiral drill 4 with the threaded chamber 7 can be spirally raised and lowered, forcing the spiral drill 4 to pass through the through groove 18 on the left side of the base 1 and drill into the ground. As the spiral drill 4 rises, more soil is extracted. After cleaning, the rotary table 2 is rotated, and the injection head 13 on the right side is moved above the hole. After the liquid pump 12 is turned on, the clear liquid is drawn through the hose 9 and the suction pipe 20 and injected into the hole. After the infiltration is completed, the pilot hole operation is performed again to compact the surrounding soil. Because the top of the worm gear 17... The end is movably installed below the base 1. By turning on the motor 14, the worm gear 15 is rotated, and the worm gear 15 guides the left worm wheel 17 to rotate in place. Depending on the progress of the project, the drilling mechanism on the left or the liquid injection mechanism on the right can be selected. The worm wheel 17 and worm gear 15 have a locking function to prevent the rotary table 2 from continuing to rotate. After the second hole-reaming operation of the spiral drill 4 is completed, the object is raised a certain distance, and then the rotating rod 23 is rotated horizontally in the sleeve block 21 to guide the bottom fixed baffle 19 to support the bottom of the spiral drill 4, preventing the bottom of the spiral drill 4 from contacting the ground and causing wear when the base 1 and the whole device are moved by the caster 11.
