Description

Technical Field

[0001] This invention belongs to the field of pipe pile construction technology, and in particular relates to a PHC pipe pile construction device based on the characteristics of terrace topography. Background Technology

[0002] PHC pipe piles are a type of precast concrete pipe pile, also known as prestressed high-strength concrete pipe piles. They consist of a pipe shell made of high-strength prestressed concrete and reinforced concrete ends. They are manufactured in one piece in a steel mold and have advantages such as controllable quality, high production efficiency, and convenient construction. They also have high pile strength, stable and reliable quality, strong penetration, simple construction site, and the lowest cost per unit bearing capacity. They are widely used in real estate construction, highway construction, railway construction, port and dock construction and other fields.

[0003] PHC pipe pile construction faces many challenges. In complex geological conditions, such as plateau landforms with hard rock layers like granite and basalt, traditional PHC pipe pile construction equipment is unable to efficiently penetrate the strata and accurately implant the pipe piles into the predetermined positions. During construction, it is necessary to use construction equipment to first drill holes at the pile driving positions and then implant the pipe piles into the drilled holes.

[0004] Currently, when existing construction equipment performs drilling operations in plateau terrain areas, the rock strata are subjected to drilling, which generates a large amount of smoke and dust. Inhalation of this smoke and dust can seriously affect human health, and the dust dispersed into the air can cause environmental pollution. Furthermore, the drilling process requires a drilling motor to drive the drill rod to rotate, and a hydraulic drive device to apply pressure to the top of the drilling motor to move the rotating drill rod downwards in order to achieve the drilling purpose. This requires multiple drive mechanisms, which increases the cost of using the equipment. If one of the drive mechanisms fails, the drilling purpose cannot be achieved, resulting in poor performance.

[0005] To address this issue, we designed a PHC pipe pile construction device based on the characteristics of terraced landforms. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] This invention relates to a PHC pipe pile construction device based on terrace topography, comprising a base plate, a fixing frame fixed to the top of the base plate, a pipe body rotatably embedded in the fixing frame, a lifting rod movably disposed inside the pipe body, a drill rod fixed to the lower end of the lifting rod, an avoidance hole penetrating through the base plate, the drill rod cooperating with the avoidance hole, several slots formed on the inner wall of the pipe body, several locking strips fixed to the outer periphery of the lifting rod, the locking strips cooperating with the slots, an adjustment mechanism provided on the fixing frame, and a cleaning mechanism provided at the bottom of the base plate. The adjustment mechanism includes:

[0008] The movable sleeve is fitted onto the lower side of the outer wall of the lifting rod, and the movable sleeve is rotatably engaged with the lifting rod. The fixed frame has through slots on both the left and right sides, and a lead screw is installed in the slot. A lifting block is threaded onto the lead screw. A connecting rod is fixed between the side of the lifting block near the tube body and the movable sleeve. A transmission assembly is provided between the lead screw and the tube body.

[0009] The transmission assembly includes a first pulley, a second pulley, and a transmission belt. The two first pulleys are vertically sleeved on the upper side of the outer wall of the tube. The upper end of the lead screw passes through the top surface of the fixed frame, and the lead screw is rotatably engaged with the fixed frame. The second pulley is fixedly sleeved on the upper side of the outer wall of the lead screw. The transmission belt is driven between adjacent first pulleys and second pulleys.

[0010] The cleaning mechanism includes two volutes fixed to the bottom of a base plate. A rotating shaft is rotatably mounted inside each volute. The upper end of the rotating shaft passes through the volute, the base plate, and the fixing frame and is connected to the lower end of a lead screw. The rotating shaft rotates in conjunction with the base plate and the fixing frame. A turbine fan is movably mounted inside each volute and is fixedly sleeved on the rotating shaft. A suction pipe is connected to one side of each volute. The end of the suction pipe away from the volute is connected to a suction hood. The suction hood is tilted downwards, and a mesh plate is fixed inside the suction hood.

[0011] The side of the vortex housing away from the suction pipe is connected to a dust conveying pipe. A purification box is provided on the rear side of the fixing frame. The purification box is fixed to the base plate and filled with clean water. The end of the dust conveying pipe away from the vortex housing is inserted through the top of the purification box and extends to the lower side of the inner cavity of the purification box. A one-way valve is installed on the dust conveying pipe.

[0012] A drainage hole is provided on the lower side of the rear surface of the purification box, and a sealing plug is provided on the drainage hole. An exhaust port is provided on the upper side of the rear surface of the purification box, and the exhaust port is connected to the inner cavity of the purification box. A transparent plate is provided on the rear surface of the purification box.

[0013] Two guide rods are fixed inside the strip groove. The two adjacent guide rods are arranged opposite each other on the front and rear sides of the lead screw. The guide rods pass through the lifting block, and the lifting block slides with the guide rods. Pull rods are fixed on both the left and right sides of the fixed frame. A servo motor is installed on the top of the fixed frame through a bracket. The output end of the servo motor is connected to the upper end of the tube.

[0014] The bottom of the base plate is equipped with several casters, which have a self-locking function. Several fixing plates are fixedly fixed at an angle to the bottom of the base plate, and hydraulic rods are installed on the fixing plates. The telescopic ends of the hydraulic rods are connected to support plates.

[0015] The present invention has the following beneficial effects:

[0016] This invention facilitates the synchronous rotation of the lead screw and the pipe body through a transmission component. The threaded engagement between the lifting block and the lead screw allows the lifting block to move downwards. Combined with the connecting rod and movable sleeve, and the movable engagement between the lifting rod and the inner cavity of the pipe body, the lifting rod moves downwards, which in turn drives the drill rod to move downwards synchronously. Furthermore, the interaction between the clamping strip and the clamping groove, along with the rotation of the pipe body, drives the lifting rod to rotate synchronously, which in turn drives the drill rod to rotate synchronously. This allows the drill rod to move downwards in a rotating state, facilitating drilling operations. It eliminates the need for multiple drive mechanisms, reducing the cost of the device. This invention solves the problems of existing construction equipment in drilling operations in plateau terrain areas, which requires a drilling motor to rotate the drill rod and a hydraulic drive device to apply pressure to the top of the drilling motor to move the rotating drill rod downwards. This requires multiple drive mechanisms, increasing the cost of the device. If one drive mechanism fails, drilling cannot be achieved, resulting in poor performance.

[0017] The process involves rotating a lead screw, which in turn drives a rotating shaft, causing the turbine fan to rotate. This creates negative air pressure inside the turbine housing, forming suction conditions. With the cooperation of the suction pipe and dust hood, the dust generated during drilling is absorbed and transported via a dust conveying pipe to the liquid level inside the purification chamber. The dust-laden air is then washed with water and collected in the upper part of the purification chamber before being discharged through the exhaust port. This effectively cleans the dust generated during drilling, solving the problems of existing drilling equipment in plateau terrain where drilling generates significant amounts of smoke and dust that can be inhaled, seriously affecting health and causing environmental pollution. This system prevents drilling dust from scattering into the air and causing environmental pollution, while also preventing dust from being inhaled. A one-way valve on the dust conveying pipe effectively prevents the water inside the purification chamber from flowing back into the dust conveying pipe, and a mesh plate effectively prevents gravel from entering the turbine housing and damaging the turbine fan, thus affecting its performance.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0035] Please see Figures 1-11 As shown, this invention is a PHC pipe pile construction device based on the characteristics of a terraced landform. It includes a base plate 1, a fixing frame 2 fixed to the top of the base plate 1, a pipe body 3 rotatably embedded in the fixing frame 2, a lifting rod 4 movably installed inside the pipe body 3, a drill rod 5 fixed to the lower end of the lifting rod 4, a clearance hole 24 penetrating through the base plate 1, the drill rod 5 cooperating with the clearance hole 24, several slots 6 formed on the inner wall of the pipe body 3, several locking strips 7 fixed to the outer periphery of the lifting rod 4, the locking strips 7 cooperating with the slots 6, an adjustment mechanism on the fixing frame 2, and a cleaning mechanism at the bottom of the base plate 1. The adjustment mechanism includes:

[0036] The movable sleeve 8 is fitted on the lower side of the outer wall of the lifting rod 4, and the movable sleeve 8 is rotatably engaged with the lifting rod 4. The fixed frame 2 has a strip groove 9 through on both the left and right sides. A screw rod 10 is installed in the strip groove 9. A lifting block 11 is threaded on the screw rod 10. A connecting rod 12 is fixed between the side of the lifting block 11 near the tube body 3 and the movable sleeve 8. A transmission component is installed between the screw rod 10 and the tube body 3.

[0037] In the above structure, the transmission assembly facilitates the synchronous rotation of the lead screw 10 and the tube body 3. With the threaded engagement between the lifting block 11 and the lead screw 10, the lifting block 11 moves downwards. Combined with the connecting rod 12, the movable sleeve 8, and the movable engagement between the lifting rod 4 and the inner cavity of the tube body 3, the lifting rod 4 moves downwards, thereby causing the drill rod 5 to move downwards synchronously. Furthermore, with the mutual engagement of the retaining strip 7 and the retaining groove 6, and the rotational engagement between the movable sleeve 8 and the lifting rod 4, the rotation of the tube body 3 drives the lifting rod 4 to rotate synchronously, which in turn drives the drill rod 5 to rotate synchronously, thus achieving... The drive drill rod 5 moves downward in a rotating state, facilitating drilling operations. It eliminates the need for multiple drive mechanisms, reducing the operating cost of the device. This solves the problem of existing construction equipment in drilling operations in plateau terrain areas, which requires a drilling motor to drive the drill rod to rotate during drilling, and a hydraulic drive device to apply pressure to the top of the drilling motor to drive the rotating drill rod downward in order to achieve the drilling purpose. This requires multiple drive mechanisms, increasing the operating cost of the device. If one of the drive mechanisms fails, the drilling purpose cannot be achieved, resulting in poor performance.

[0038] The transmission assembly includes a first pulley 13, a second pulley 14, and a transmission belt 15. The two first pulleys 13 are vertically sleeved on the upper side of the outer wall of the tube body 3. The upper end of the lead screw 10 passes through the top surface of the fixed frame 2, and the lead screw 10 is rotatably engaged with the fixed frame 2. The second pulley 14 is fixedly sleeved on the upper side of the outer wall of the lead screw 10. The transmission belt 15 is driven between the adjacent first pulleys 13 and second pulleys 14. Through the mutual cooperation of the first pulleys 13, second pulleys 14, and transmission belt 15, the tube body 3 and the lead screws 10 on both sides are driven to rotate synchronously.

[0039] The cleaning mechanism includes two volutes 16, which are fixed to the bottom of the base plate 1. A rotating shaft 17 is rotatably installed inside the volute 16. The upper end of the rotating shaft 17 passes through the volute 16, the base plate 1, and the fixing frame 2 and is connected to the lower end of the lead screw 10. The rotating shaft 17 is rotatably engaged with the base plate 1 and the fixing frame 2. A turbine fan 18 is movably installed inside the volute 16 and is fixedly sleeved on the rotating shaft 17. A suction pipe 19 is connected to one side of the volute 16. The end of the suction pipe 19 away from the volute 16 is connected to a suction hood 20. The suction hood 20 is tilted downwards, and a mesh plate 21 is fixed inside the suction hood 20.

[0040] A dust conveying pipe 22 is connected to the side of the vortex shell 16 away from the suction pipe 19. A purification box 23 is set on the rear side of the fixing frame 2. The purification box 23 is fixed on the base plate 1 and filled with clean water. The end of the dust conveying pipe 22 away from the vortex shell 16 is inserted through the top of the purification box 23 and extends to the lower side of the inner cavity of the purification box 23. A one-way valve is installed on the dust conveying pipe 22. A drain hole is opened on the lower side of the rear surface of the purification box 23. A sealing plug 25 is set on the drain hole. An exhaust port 26 is opened on the upper side of the rear surface of the purification box 23. The exhaust port 26 is connected to the inner cavity of the purification box 23. A transparent plate 27 is set on the rear surface of the purification box 23.

[0041] In the above structure, the rotation of the lead screw 10 drives the rotating shaft 17 to rotate synchronously, which in turn drives the turbine fan 18 to rotate. This creates a negative air pressure inside the turbine housing 16, forming suction conditions. With the cooperation of the suction pipe 19 and the suction hood 20, the dust generated during the drilling process of the drill rod 5 is absorbed and transported to the liquid level inside the purification box 23 via the dust conveying pipe 22. The dust-laden air is then washed with water and collected in the upper layer inside the purification box 23, and finally discharged through the exhaust port 26. This achieves the purpose of cleaning the dust generated during the drilling process, preventing the dust generated during drilling from drifting into the air and causing environmental pollution, while also preventing the dust from being inhaled by the human body. The one-way valve on the dust conveying pipe 22 effectively prevents the water inside the purification box 23 from flowing back into the dust conveying pipe 22, while the mesh plate 21 effectively prevents gravel from entering the turbine housing 16 and damaging the turbine fan 18, thus affecting its performance.

[0042] Two guide rods 28 are fixed inside the strip groove 9. The two adjacent guide rods 28 are arranged opposite each other on the front and rear sides of the lead screw 10. The guide rods 28 pass through the lifting block 11. The lifting block 11 slides with the guide rods 28. The guide rods 28 effectively limit and guide the lifting block 11, ensuring the stability of the lifting block 11 during its up and down movement. Pull rods 29 are fixed on both the left and right sides of the fixed frame 2. A servo motor 30 is installed on the top of the fixed frame 2 through a bracket. The output end of the servo motor 30 is connected to the upper end of the tube body 3.

[0043] The bottom of the base plate 1 is equipped with several casters 31, which have a self-locking function. Several fixing plates 32 are fixedly fixed at the bottom of the base plate 1 at an angle. Hydraulic rods 33 are installed on the fixing plates 32, and the telescopic ends of the hydraulic rods 33 are connected to support plates 34. Example:

[0044] When drilling is required at the construction site for PHC pipe piles in areas with terrace topography, the entire device is first moved to the position where the PHC pipe pile needs to be implanted under the action of the caster wheel 31, so that the clearance hole 24 is located directly above the PHC pipe pile implantation position. At this time, the caster wheel 31 is fixed, and the hydraulic rod 33 is activated to push the support plate 34 closer to the ground until the support plate 34 contacts the ground, so as to increase the contact area and friction between the bottom of the base plate 1 and the ground, and ensure the overall stability of the device.

[0045] During real-time drilling, the servo motor 30 is started first, and the tube body 3 is driven to rotate by the servo motor 30. With the cooperation of the first pulley 13, the second pulley 14 and the transmission belt 15, the lead screws 10 on both sides are driven to rotate synchronously.

[0046] As the tube body 3 rotates, the lifting rod 4 rotates synchronously. With the cooperation of the locking strip 7 and the locking groove 6, the drill rod 5 rotates synchronously.

[0047] Simultaneously, with the threaded engagement between the lifting block 11 and the lead screw 10, and the sliding engagement between the lifting block 11 and the guide rod 28, the lifting block 11 is driven to move downward steadily. With the movable engagement between the connecting rod 12, the movable sleeve 8, and the lifting rod 4 and the inner cavity of the pipe body 3, and the rotational engagement between the movable sleeve 8 and the lifting rod 4, the lifting rod 4 is driven to move downward, which in turn drives the drill rod 5 to move downward synchronously. This achieves the simultaneous rotation and downward movement of the drill rod 5 until the drill rod 5 passes through the clearance hole 24 and drills into the ground, realizing the drilling operation in the PHC pipe pile construction process without the need to set up multiple drive mechanisms, thus reducing the operating cost of the device.

[0048] During the rotation of the lead screw 10, the rotating shaft 17 rotates synchronously, which in turn drives the turbine fan 18 to rotate. This creates a negative air pressure inside the turbine housing 16, forming suction conditions. With the cooperation of the suction pipe 19 and the suction hood 20, the dust generated during the drilling process of the drill rod 5 is absorbed and transported to the liquid level inside the purification box 23 via the dust conveying pipe 22. After the dust-laden air is washed with water, it is collected in the upper layer inside the purification box 23 and finally discharged through the exhaust port 26. This achieves the purpose of cleaning the dust during the drilling process, preventing the dust generated during drilling from drifting into the air and causing environmental pollution, while also preventing the dust from being inhaled by the human body.

[0049] Meanwhile, the mesh plate 21 effectively prevents gravel from entering the vortex shell 16 and damaging the turbine fan 18, thus affecting its performance.

[0050] After drilling is completed, the sealing plug 25 is pulled out, the water used to wash the dusty air inside the purification box 23 is discharged, and new liquid is injected through the exhaust port 26 to continue the cleaning of dust during the drilling process.

[0051] The transparent plate 27 allows for easy observation of the water level inside the purification tank 23, and facilitates control of the amount of water injected into the purification tank 23.

[0052] Finally, the PHC pipe piles are inserted into the drilled holes to complete the construction of the PHC pipe piles.

[0053] It should be further noted that the installation structure, connection method or setting method of each component in this invention are all common mechanical methods. As long as they can achieve their beneficial effects, they can be implemented. At the same time, the servo motor 30 and hydraulic rod 33 in this invention are all purchased from the market.
