Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a protective tool for corrugated pipe drilling. Background Technology

[0002] With the increasing use of post-tensioned prestressed box girders in bridge construction, it is necessary to install perforated corrugated pipes before pouring concrete inside the box girder. However, the corrugated pipes are easily damaged during construction and concrete pouring, causing grout leakage and insufficient inner diameter of the perforated pipe, thus preventing the installation of the steel strands. The traditional method involves adding a rigid PE pipe inside the corrugated pipe, but due to the pipe's bending and length, the installation and removal of the rigid pipe are difficult. After construction, when pulling out the pipe, it is easy for it to break and remain inside the corrugated pipe.

[0003] Patent CN 221608642 U discloses a quick-installation and dismantling internal support device for preventing deformation of corrugated steel pipe culverts. The device includes a telescopic vertical support rod and a telescopic horizontal support rod perpendicular to the vertical support rod. Both ends of the vertical support rod and the horizontal support rod are provided with corrugated pad bases. The corrugated shape of the corrugated pad bases is adapted to the corrugation inside the corrugated steel pipe culvert. Sensors for sensing the stress and deformation of the corrugated steel pipe culvert are provided on the corrugated pad bases at both ends of the vertical support rod.

[0004] However, the device still has the following problems:

[0005] 1. This support device is only suitable for supporting corrugated pipes with larger diameters. For corrugated pipes with smaller diameters and longer lengths, the device is difficult to insert into the deeper parts of the corrugated pipe, and the support effect for corrugated pipes with smaller diameters is not ideal.

[0006] 2. After the corrugated pipe is inserted, each support device needs to be adjusted individually, and each one also needs to be disassembled individually after the support is completed, which is time-consuming and labor-intensive. Utility Model Content

[0007] In order to solve the problems existing in the prior art, a corrugated pipe hole forming protection tool is provided to solve the problems mentioned in the above technical background.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] This utility model proposes a corrugated pipe perforation protection tool, including a water bag and a clamping head. The water bag is a hollow tube with openings at both ends. One end of the clamping head is a clamping end that can clamp the end of the water bag. The other end of the clamping head is detachably connected to a traction head. The traction head is equipped with a traction rope, which is connected to a rope take-up wheel. The rope take-up wheel is directly connected to a power component. The tool also includes a filling mechanism for filling the water bag.

[0010] Preferably, the clamping end includes a plurality of elastic clamping plates, the clamping plates are disposed on the inner wall of one end of the clamping head and are at an angle to the inner wall, the outer wall of the clamping head extends outward to form a clamping tube, and a receiving cavity for accommodating the end of the water bag is formed between the clamping tube and the plurality of clamping plates.

[0011] Preferably, the clamping head is coaxially fitted with a tapered tightening head, one end of which engages with the clamping plate, and the other end is threadedly connected to the clamping head.

[0012] Preferably, the tightening head has a filling cavity, one end of which is connected to the inside of the water bag, and the other end is provided with a filling port, which is detachably connected to the filling mechanism.

[0013] Preferably, the clamping head has a detection cavity that is connected to the interior of the water bag. A piston slides inside the detection cavity and is fixed to the clamping head by a compression spring. A switch is fixed to the clamping head and is connected to the filling mechanism. The piston cooperates with the switch.

[0014] Preferably, a ball is provided inside the filling port, the ball can seal the filling port, and the ball is fixed to the filling port by a spring.

[0015] Preferably, the clamping head has a plurality of lubricating wheels evenly distributed in the circumferential direction, the lubricating wheels are adsorbed with lubricant, the clamping head has a plurality of lubricating grooves, the lubricating grooves are filled with lubricant, and the lubricating wheels are rotatably disposed in the lubricating grooves.

[0016] Preferably, the inner wall of the clamping head extends outward to form a conical tube, the clamping plate is fixed to the conical tube and is evenly distributed along the circumference of the conical tube, and the end of the water bag is sleeved on the conical surface of the conical tube.

[0017] Preferably, the clamping plate has several grooves, and the clamping tube has several protrusions that cooperate with the grooves.

[0018] Preferably, the filling mechanism includes a water tank, a water pump is installed inside the water tank, the water pump is connected to a water supply pipe, and the water supply pipe is connected to the filling port.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model is equipped with a clamping head, one end of which has a traction rope. The traction rope is tightened by a power component, causing the traction rope to pull the clamping head to move inside the corrugated pipe. The clamping head then pulls the water bag through the corrugated pipe, placing the water bag inside the corrugated pipe along the radial direction. After the water bag is placed inside the corrugated pipe, it is inflated with air or water, so that the water bag fits against the inner wall of the corrugated pipe. The gas or liquid inside the water bag provides support for the corrugated pipe. This invention is suitable for corrugated pipes with small diameter and long length, which facilitates construction and reduces construction costs. It also helps to reduce the risk of breakage and loss of traditional inner lining pipes.

[0021] 2. This utility model is equipped with an elastic clamping plate that works in conjunction with the clamping tube to clamp the water bag, which helps to keep the water bag fixed to the clamping head. At the same time, the clamping head is internally threaded with a conical tightening head. The tightening head is threaded to the clamping head. When the tightening head is rotated, the conical surface of the tightening head will drive the clamping plate to move closer to the clamping tube, further reducing the distance between the clamping plate and the clamping tube. This helps to increase the clamping force on the water bag during traction and reduce the risk of the water bag falling off.

[0022] 3. The clamping head of this utility model is provided with a detection chamber, in which a piston slides. The piston is connected to a switch, and a compression spring is fixedly connected between the piston and the clamping head. When the water bag is filled with air or water, the piston will slide after a certain pressure is reached, which will compress the compression spring. When the water pressure or air pressure in the water bag reaches the preset value, the piston slides to the switch position and presses the switch. The switch is connected to the filling mechanism, which stops the filling mechanism from working and avoids excessive pressure in the water bag, which could cause the corrugated tube to deform.

[0023] 4. This utility model has several lubricating wheels on the clamping head. The lubricating wheels have lubricant. When the clamping head pulls the water bag forward, the lubricating wheels can apply lubricant to the inner wall of the corrugated tube. When the water bag moves forward, the lubricant can not only reduce friction, but also reduce wear between the water bag and the corrugated tube. It can also adapt to the arrangement of water bags in a long corrugated tube. Attached Figure Description

[0031] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0032] like Figures 1-4 As shown, this embodiment proposes a corrugated pipe perforation protection tool, including a water bag 1 and a clamping head 2. The water bag 1 is a tube with a hollow interior and open ends. One end of the clamping head 2 is a clamping end, which can clamp the end of the water bag 1. The other end of the clamping head 2 is detachably connected to a traction head 3 by a thread. The traction head 3 is provided with a traction rope 4, which is connected to a rope winding wheel. The rope winding wheel is directly connected to a power component. It also includes a filling mechanism for filling the water bag 1.

[0033] The corrugated pipe 22 is placed inside the prestressed concrete beam 23.

[0034] Water bag 1 is made of PE. PE water bags have good flexibility and can adapt to different usage scenarios and environments. When subjected to external pressure or collision, the water bag can be flexibly deformed without easily breaking.

[0035] The traction head 3 has a traction hole 19, and the traction rope 4 passes through the traction hole 19 and is then knotted and fixed.

[0036] The power component is an electric motor or motor.

[0037] The power unit drives the rope take-up wheel to rotate, which can gather the traction rope 4. The traction rope 4 drives the traction head 3 to move, and the traction head 3 in turn drives the water bag 1 to move inside the corrugated pipe 22, so that the water bag 1 is placed inside the corrugated pipe 22 in the radial direction. After placement, the filling mechanism fills the water bag 1. The liquid or gas in the water bag makes the water bag adhere to the inner wall of the corrugated pipe, forming a support for the corrugated pipe 22. This facilitates construction and reduces construction costs, and helps to reduce the risk of traditional inner lining pipes breaking and falling off easily.

[0038] After use, simply expel the gas or liquid from the water bag, and the water bag will shrink in size, reducing friction with the corrugated tube and making it easier to remove, saving time and effort.

[0039] The clamping end includes several elastic clamping plates 6. The clamping plates 6 are fixedly disposed on the inner wall of one end of the clamping head 2 and are at an angle to the inner wall. The outer wall of the clamping head 2 extends outward to form a clamping tube 7. The clamping tube 7 and the several clamping plates 6 form a receiving cavity for accommodating the end of the water bag 1.

[0040] Place one end of the water bag 1 into the receiving cavity. The clamping plate 6 and the clamping tube 7 cooperate to clamp the water bag 1, which helps to keep the water bag 1 and the clamping head 2 fixed.

[0041] A tapered clamping head 8 is coaxially inserted through the clamping head 2. One end of the clamping head 8 is engaged with the clamping plate 6, and the other end is threadedly connected to the clamping head 2.

[0042] By rotating the clamping head 8, relative movement occurs between the clamping head 8 and the clamping head 2 under the action of the thread. The conical surface of the clamping head 8 abuts against the clamping plate 6, gradually driving the clamping plate 6 to move closer to the clamping tube 7, thereby further reducing the distance between the clamping plate 6 and the clamping tube 7, and thus further clamping the water bag 1.

[0043] The tightening head 8 has a filling cavity inside. One end of the filling cavity is connected to the water bag 1, and the other end is provided with a filling port 9. The filling port 9 is detachably connected to the filling mechanism.

[0044] After the traction head 3 is removed from the clamping head 2, the water bag 1 is filled through the tightening head 8. There is no need to repeatedly remove the clamping head 2. After the clamping head 2 pulls the water bag 1 out of the corrugated pipe 22, the water bag can be filled directly through the tightening head 8, which is convenient to operate.

[0045] The clamping head 2 has a detection chamber that is connected to the inside of the water bag 1. A piston 10 slides inside the detection chamber and is fixed to the clamping head 2 by a compression spring 11. A switch 12 is fixed on the clamping head 2 and is connected to the water supply device. The piston 10 cooperates with the switch 12.

[0046] Switch 12 is specifically a push-button spring switch, which typically consists of a push button, a spring, a mounting base, and conductive contacts. The push button is usually made of plastic or metal and possesses a certain degree of pressing performance and mechanical strength. The spring's function is to allow the button to automatically return to its original position and ensure its elasticity when pressed. The mounting base is used to secure the button and spring, ensuring their positions do not change. The conductive contacts are the crucial part connecting the circuit; pressing the button connects or disconnects the circuit through the contacts, thus achieving the switch's function.

[0047] When the water bag 1 is inflated with air or water, the piston 10 will slide after the water bag 1 reaches a certain pressure, which will compress the spring 11. When the water pressure or air pressure in the water bag 1 reaches the preset value, the piston 10 will slide to the switch 12 position, and the switch 12 will be pressed to cut off the power. The switch 12 is connected to the filling mechanism, which will cut off the power to the filling mechanism and stop it from working, so as to avoid excessive pressure in the water bag and deformation of the corrugated tube.

[0048] A ball 16 is provided inside the filling port 9. The ball 16 can block the filling port 9. The ball 16 and the filling port 9 are fixed together by a spring 17.

[0049] After filling is completed, the spring 17 causes the ball 16 to seal the filling port 9, which helps to maintain the seal and improve the support strength.

[0050] The clamping head 2 has several lubricating wheels 5 evenly distributed around its circumference. The lubricating wheels 5 are coated with lubricant. The clamping head 2 has several lubricating grooves 18, which contain lubricant. The lubricating wheels 5 are rotatably positioned within the lubricating grooves 18.

[0051] A sponge is placed inside the lubrication groove 18. The sponge absorbs lubricant. The lubrication wheel 5 is in contact with the sponge. As the lubrication wheel 5 rotates, the sponge continuously applies lubricant to the lubrication wheel 5.

[0052] When the traction head 2 slides with the water bag 1 inside the bellows 22, the lubrication wheel 5 contacts the inner wall of the bellows 22. As the lubrication wheel 5 rolls along the inner wall of the bellows 22, the lubricant adsorbed on the lubrication wheel 5 is applied to the inner wall of the bellows 22. Subsequently, when the water bag 1 slides along the inner wall of the bellows 22, it helps to reduce friction and reduce wear between the water bag 1 and the bellows 22. It can also accommodate the arrangement of the water bag 1 inside a longer bellows 22.

[0053] The inner wall of the clamping head 2 extends outward to form a conical tube 13. The clamping plate 6 is fixed to the conical tube 13 and is evenly distributed along the circumference of the conical tube 13. The end of the water bag 1 is sleeved on the conical surface of the conical tube 13.

[0054] The water bag 1 can be fitted onto the tapered tube 13. The tapered tube 13 can accommodate water bags 1 with different inner diameters. Furthermore, fitting the water bag 1 onto the tapered tube 13 can better seal the opening of the water bag 1.

[0055] The clamping plate 6 has several grooves 14, and the clamping tube 7 has several protrusions 15 that cooperate with the grooves 14.

[0056] When the clamping plate 6 and the clamping tube 7 clamp the water bag 1, the groove 14 and the protrusion 15 cooperate to make the water bag 1 serrated or wavy between the clamping plate 6 and the clamping tube 7, which increases the clamping area and friction, which helps to improve the clamping force of the clamping plate 6 and the clamping tube 7 on the water bag 1 and effectively reduces the water bag 1 from falling off during the traction process.

[0057] The filling mechanism includes a water tank, a water pump is installed inside the water tank, the water pump is connected to a water supply pipe 20, and the water supply pipe 20 is connected to the filling port 9 by a thread.

[0058] A push rod 21 is fixed inside the water supply pipe 20. After the water supply pipe 20 is connected to the filling port 9, the push rod 21 squeezes the ball 16, causing the spring 17 to compress. At this time, the filling port 9 opens, allowing filling to be done through the filling port 9.

[0059] The filling mechanism can also be used for an air pump, which supplies air to the water bag through an air tube.

[0060] Specific work process:

[0061] S1: After the corrugated pipe 22 is placed inside the prestressed concrete beam 23, one end of the water bag 1 is fitted between the clamping plate 6 and the clamping pipe 7, and the water bag 1 is fitted onto the tapered pipe 13. Then, the tightening head 8 is rotated so that the tapered surface of the tightening head 8 gradually pushes the clamping plate 6 close to the clamping pipe 7 to clamp the water bag 1.

[0062] S2: The winding wheel is driven to rotate by the power component. The winding wheel gathers the traction rope 4. The traction rope 4 pulls the clamping head 2 and the water bag 1 through the traction head 3 to slide inside the corrugated tube 22. During the sliding process, the lubrication wheel 5 applies lubricant along the inner wall of the corrugated tube 22 to lubricate the subsequent sliding of the water bag 1.

[0063] S3: After the water bag 1 slides out from the other end of the corrugated pipe 22 along with the traction head 3, rotate and disassemble the traction head 3 to expose the filling port 9. Connect the water supply pipe 20 to the filling port 9. The top rod 21 squeezes the ball 16 to compress the spring 17. At this time, the filling port 9 opens, and the water pump in the water tank supplies water to the filling port 9 and the water bag 1 through the water supply pipe 20.

[0064] S4: During the filling process, the water flow will push the piston 10 to slide, compress the spring 11, and after the water pressure in the water bag 1 reaches the preset value, the piston 10 will contact the switch 12, and the switch 12 will turn off the power, turn off the water pump in the water tank, and stop the water supply.

[0065] S5: Fill the prestressed concrete beam 23 with concrete. After pouring, drain the water from the water bag 1 and then extract it from the corrugated pipe 22 to complete the construction.

[0066] In S1, the clamping head 2 is inserted through a steel wire from one end of the corrugated pipe 22 to the other end, or before the corrugated pipe 22 is placed into the prestressed concrete beam 23, the corrugated pipe 22 is tilted, and gravity is used to make the clamping head 2 slide from one end of the corrugated pipe 22 to the other end, so that the traction rope completely passes through the corrugated pipe 22 for easy traction.

[0067] In S1, one end of the water bag 1 is fixed and sealed by the clamping head 2, and the other end is also sealed by the clamping head 2, or by binding and sealing with a binding rope.
