Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a top-pressure type pile hole protector. Background Technology

[0002] In urban construction projects, vibration and noise issues during pile foundation construction often lead to numerous complaints from surrounding residents. Therefore, static pressure piles are frequently used for pile foundation construction. The construction principle of static pressure piles is as follows: the pile driving mechanism of the static pile driver uses the pile driver's own weight and the counterweight on the frame to provide reaction force to press the precast pile into the soil. It has advantages such as no damage to the pile, no noise, no vibration, no impact force, and no pollution, completely avoiding the vibration, noise, and pollution generated by hammer pile driving.

[0003] However, static pressure pile construction leaves many circular openings in the ground. Since precast piles range in length from several meters to over ten meters, these open openings not only pose significant construction safety hazards, but also allow debris such as soil to fall into them, affecting construction quality. Currently, steel plates are typically used to cover the openings of static pressure piles on construction sites, but this method offers poor protection. Therefore, a top-pressure type pile hole protector is needed to address the problem of poor protection for static pressure pile openings in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a top-pressure pile hole protector that can solve the problem of poor protection effect at the opening of static pressure piles in the prior art.

[0005] This invention is implemented as follows:

[0006] A top-pressure type pile hole protector includes a top-pressure cylinder, a cover plate, a top-pressure adjustment assembly, and top-pressure blocks. The cover plate covers the opening of the static pressure pile, and the lower part of the cover plate is inserted into the pipe pile. The lower part of the top-pressure cylinder is vertically inserted into the cover plate, and the upper part of the top-pressure cylinder extends above the cover plate. The top-pressure adjustment assembly is located at the lower part of the cover plate and inside the pipe pile, and several sets of top-pressure adjustment assemblies are spaced apart along the lower circumference of the cover plate. Several top-pressure blocks are respectively arranged on several sets of top-pressure adjustment assemblies, and the bottom surface of the top-pressure cylinder movably abuts against the top of several sets of top-pressure adjustment assemblies, so that several top-pressure blocks can be pressed against the inner wall of the pipe pile by several sets of top-pressure adjustment assemblies.

[0007] The cover plate includes a cover plate portion and an insert portion; the inner diameter of the cover plate matches the outer diameter of the pipe pile, so that the cover plate fits over the top of the pipe pile; the outer diameter of the insert portion is smaller than the inner diameter of the pipe pile, and the insert portion is coaxially installed at the bottom of the cover plate portion, so that the insert portion can be inserted into the pipe pile; the top pressure cylinder can be lifted and inserted into the insert portion, and several sets of top pressure adjustment components are spaced apart at the bottom of the insert portion.

[0008] The inner wall of the insert portion has an internal thread, and the lower outer wall of the pressure cylinder has an external thread. The external thread matches the internal thread, so that the lower part of the pressure cylinder can be rotated and inserted into the insert portion.

[0009] The top of the pressure cylinder is equipped with a screw handle.

[0010] The top of the pressure cylinder has a transparent chamber, and several lighting lamps are installed inside the transparent chamber.

[0011] Each set of top pressure adjustment components includes a first mounting frame, a second mounting frame, and a pressure bar; the upper end of the first mounting frame is fixedly mounted on the lower part of the insert portion by a mounting component, the upper part of the second mounting frame is movably inserted into the first mounting frame, and the lower end of the second mounting frame extends to the bottom of the first mounting frame; a through hole is formed on the second mounting frame for the pressure bar to pass through, so that the pressure bar passes through the through hole and through the second mounting frame, and the bottom surface of the top pressure cylinder movably abuts against one end of the pressure bar, and the top pressure block is mounted on the other end of the pressure bar.

[0012] The first mounting frame is provided with a first limiting plate and a spring. The spring is sleeved on the upper part of the second mounting frame, and the upper end of the spring and the upper end of the second mounting frame can abut against the first limiting plate, while the lower end of the spring can abut against the bottom of the inner wall of the first mounting frame.

[0013] The through hole has a trapezoidal structure with one end larger than the other, and the larger end of the through hole faces the inner wall of the pipe pile, so that the pressure rod can be vertically rotated through the second mounting frame, and the lower end of the pressure rod extends outward and downward at an angle.

[0014] A second limiting plate is formed on the pressing rod, and the second limiting plate is located inside the small end of the through hole; one end of the second limiting plate abuts against the second mounting frame above the through hole, and the pressing rod is attached to the bottom inclined side of the through hole.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This invention is equipped with a top pressure cylinder, a top pressure adjustment component, and a top pressure block. The top pressure cylinder is raised and lowered by rotating the screw thread. When it descends, it presses down on the upper end of the pressure rod, causing the top pressure block at the lower end of the pressure rod to rotate outward and upward and press against the inner wall of the pipe pile. This fixes the cover plate on the top of the pipe pile, providing effective protection at the opening of the static pressure pile and avoiding construction safety hazards. The disassembly type only requires rotating the top pressure cylinder in the opposite direction, making it simple to operate and easy to disassemble and assemble.

[0017] 2. Because the present invention has a cover plate, the cover plate covers the pipe pile, which facilitates the sealing of the pipe pile opening. At the same time, the insert part is inserted into the pipe pile, which not only ensures the installation stability of the protector on the pipe pile, but also facilitates the installation and use of the pressure cylinder and the pressure adjustment component.

[0018] 3. Because the invention has a top pressure cylinder with a transparent chamber and a light, it can provide illumination and warning at night, prevent people and vehicles from hitting the top pressure cylinder, and ensure that the top pressure cylinder is not damaged and can be used normally.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Please see the appendix Figure 1 To be continued Figure 3A top-pressure type pile hole protector includes a top-pressure cylinder 1, a cover plate 2, a top-pressure adjustment assembly, and top-pressure blocks 7. The cover plate 2 covers the opening of the static pressure pile, and the lower part of the cover plate 2 is inserted into the pipe pile (not shown in the figure). The lower part of the top-pressure cylinder 1 is vertically inserted into the cover plate 2, and the upper part of the top-pressure cylinder 1 extends above the cover plate 2. The top-pressure adjustment assembly is set at the lower part of the cover plate 2 and located inside the pipe pile. Several sets of top-pressure adjustment assemblies are spaced apart along the lower circumference of the cover plate 2. Several top-pressure blocks 7 are respectively set on several sets of top-pressure adjustment assemblies. The bottom surface of the top-pressure cylinder 1 movably abuts against the top of several sets of top-pressure adjustment assemblies, so that several top-pressure blocks 7 can be pressed against the inner wall of the pipe pile by several sets of top-pressure adjustment assemblies.

[0032] The cover plate 2 is used to cover the opening of the static pressure pile, which can play a role in protecting the opening. The jacking cylinder 1 works with the jacking adjustment component to press the jacking block 7 against the inner wall of the pipe pile, so that the cover plate 2 is locked at the opening of the static pressure pile and will not be displaced due to external disturbance, thus ensuring the effectiveness of the opening protection.

[0033] The number of top pressure adjustment components and top pressure blocks 7 is the same, preferably four sets of top pressure adjustment components and four top pressure blocks 7. The four top pressure blocks 7 are arranged at equal intervals to ensure that a uniform force is applied to the inner wall of the pipe pile. Preferably, the top pressure blocks 7 can be made of rubber material, which has a certain deformation capacity and good friction to ensure the compression and locking stability between the top pressure blocks 7 and the inner wall of the pipe pile, thereby ensuring that the cover plate 2 does not fall off.

[0034] Preferably, the cover plate 2 and the top pressure cylinder 1 can be covered by a cover body, which can play a role in waterproofing and theft prevention.

[0035] Please see the appendix Figure 5 The cover plate 2 includes a cover plate portion 201 and an insert portion 202; the inner diameter of the cover plate 201 matches the outer diameter of the pipe pile, so that the cover plate 201 fits over the top of the pipe pile; the outer diameter of the insert portion 202 is smaller than the inner diameter of the pipe pile, and the insert portion 202 is coaxially installed at the bottom of the cover plate portion 201, so that the insert portion 202 can be inserted into the pipe pile; the pressure cylinder 1 is vertically and retractably inserted into the insert portion 202, and several sets of pressure adjustment components are spaced apart at the bottom of the insert portion 202, as shown in the attached figure. Figure 4 Appendix Figure 6 To be continued Figure 8 As shown.

[0036] The cover plate 201 can be made of steel plate. The cover plate 201 has a cover-like structure, which makes it easy to match and install with the top of the pipe pile and is not easy to fall off. The insert part 202 is inserted into the pipe pile, which can not only improve the covering stability of the cover plate 201, but also facilitate the installation of the top pressure adjustment component.

[0037] An internal thread 203 is formed on the inner wall of the insert portion 202, and an external thread 101 is formed on the lower outer wall of the pressure cylinder 1. The external thread 101 matches the internal thread 203, so that the lower part of the pressure cylinder 1 is rotated and inserted into the insert portion 202.

[0038] The top pressure cylinder 1 is moved up and down relative to the insert part 202 by using threaded transmission, thereby moving the top pressure cylinder 1 down and applying downward pressure to the top pressure adjustment component, or moving the top pressure cylinder 1 up and releasing the top pressure adjustment component.

[0039] The top of the pressure cylinder 1 is provided with a screw handle 102, which makes it easy to hold and rotate the pressure cylinder 1, making the operation more convenient and labor-saving.

[0040] Please see the appendix Figure 9 and attached Figure 10 Each set of top pressure adjustment components includes a first mounting frame 6, a second mounting frame 8, and a pressure rod 9; the upper end of the first mounting frame 6 is fixedly mounted on the lower part of the insert part 202 by the mounting part 3, the upper part of the second mounting frame 8 is movably inserted into the first mounting frame 6, and the lower end of the second mounting frame 8 extends to the bottom of the first mounting frame 6; a through hole 801 is formed on the second mounting frame 8 for the pressure rod 9 to pass through, so that the pressure rod 9 passes through the through hole 801 through the second mounting frame 8, and the bottom surface of the top pressure cylinder 1 movably abuts against one end of the pressure rod 9, and the top pressure block 7 is mounted on the other end of the pressure rod 9.

[0041] The first mounting frame 6 can adopt a U-shaped structure, providing space for the second mounting frame 8 to be inserted and moved vertically. The upper part of the second mounting frame 8 is inserted into the space of the first mounting frame 6, and the lower part of the second mounting frame 8 is fitted with a pressure rod 9 through a through hole 801. The pressure rod 9 can rotate relative to the second mounting frame 8. Due to the restriction of the through hole 801, when the upper end of the pressure rod 9 is subjected to downward pressure, the lower end of the pressure rod 9 rotates upward and outward, thereby driving the top pressure block 7 to rotate upward and outward synchronously, thus pressing the top pressure block 7 tightly against the inner wall of the pipe pile.

[0042] Preferably, mounting component 3 can be made of bolts, which makes disassembly and assembly convenient and quick.

[0043] Please see the appendix Figure 9 and attached Figure 10 The first mounting frame 6 is provided with a first limiting plate 4 and a spring 5. The spring 5 is sleeved on the upper part of the second mounting frame 8, and the upper end of the spring 5 and the upper end of the second mounting frame 8 can abut against the first limiting plate 4, and the lower end of the spring 5 can abut against the bottom of the inner wall of the first mounting frame 6.

[0044] Because the pressure bar 9 is subjected to the downward pressure of the top pressure cylinder 1, the downward pressure is transmitted to the second mounting frame 8, compressing the spring 5. The elastic force of the spring 5 provides a buffer, preventing the first mounting frame 6 and the second mounting frame 8 from falling off. The elastic force of the spring 5 can also adjust the downward pressure of the top pressure cylinder 1. At the same time, the spring 5 stores energy to facilitate the reset of the second mounting frame 8, the pressure bar 9, and the top pressure block 7 when the top pressure cylinder 1 releases the pressure bar 9.

[0045] Please see the appendix Figure 9 and attached Figure 10 The through hole 801 has a trapezoidal structure with one end larger than the other end, and the larger end of the through hole 801 is set facing the inner wall of the pipe pile, so that the pressure rod 9 can be vertically rotated through the second mounting frame 8, and the lower end of the pressure rod 9 extends outward (i.e. towards the inner wall of the pipe pile) and downward.

[0046] The trapezoidal through-hole 801 allows for both through-installation of the pressure rod 9 and rotation of the pressure rod 9 within the flared range of the trapezoid. This enables the pressure rod 9 to rotate and cause the pressure block 7 to press against the inner wall of the pipe pile when it is squeezed by the pressure cylinder 1.

[0047] Preferably, the diameter of the small end of the through hole 801 is slightly larger than the diameter of the pressing rod 9, which can ensure that the pressing rod 9 has a rotation function while preventing the pressing rod 9 from being displaced horizontally or vertically.

[0048] Please see the appendix Figure 9 and attached Figure 10 A second limiting plate 901 is formed on the pressing rod 9. The second limiting plate 901 is located inside the small end of the through hole 801 (i.e., the side away from the inner wall of the pipe pile). One end of the second limiting plate 901 abuts against the second mounting frame 8 above the through hole 801, and the pressing rod 9 is attached to the bottom inclined side of the through hole 801.

[0049] When the upper end of the pressure bar 9 is subjected to downward pressure, since one end of the second limiting plate 901 abuts against the second mounting frame 8, a fulcrum of the lever structure is formed above the through hole 801. The top pressure block 7 at the lower end of the pressure bar 9 rotates upward and squeezes the inner wall of the pipe pile, using friction to lock the cover plate 201 to the top of the pipe pile.

[0050] Meanwhile, through the setting of the second limiting plate 901 and the trapezoidal through hole 801, the pressure rod 9 can be in a downward and outward inclined state along the bottom inclined side of the through hole 801. When the top pressure cylinder 1 acts downward on the top of the pressure rod 9, the pressure rod 9 can rotate with one end of the second limiting plate 901 as the fulcrum, driving the top pressure block 7 to rotate outward and upward, so as to achieve the purpose of pressing the inner wall of the pipe pile.

[0051] The pressure bar 9, the second limiting plate 901, and the second mounting frame 8 form a triangular structure. The rotation range of the pressure bar 9 can be limited by the bottom and top inclined surfaces of the through hole 801, or by the contact between the second limiting plate 901 and the second mounting frame 8.

[0052] Conversely, after the top pressure cylinder 1 releases the pressure rod 9, the pressure rod 9 rotates in the opposite direction, causing the top pressure block 7 to disengage from the inner wall of the pipe pile, thereby allowing the cover plate 201 to be removed.

[0053] Preferably, the size of the second limiting plate 901 is larger than the small end size of the through hole 801, and the size of the top pressing block 7 is larger than the large end size of the through hole 801, which can prevent the pressing rod 9 from coming out of the through hole 801. The pressing rod 9 can be made of high-strength steel material with strong shear and bending resistance to ensure that the pressing rod 9 will not bend, deform or break.

[0054] The top of the pressure cylinder 1 has a transparent chamber (not shown in the figure), and several lighting lamps (not shown in the figure) are installed in the transparent chamber.

[0055] By installing lighting, both illumination and warning functions can be achieved, thus improving the protection of openings. Preferably, the number and brightness of the lighting fixtures can be adapted to actual usage needs. The lighting fixtures can use existing solar-powered LED lights, which are energy-saving and environmentally friendly, or LED lights powered by battery packs.

[0056] All components of the entire protective device are assembled using detachable methods such as bolts, making disassembly convenient.

[0057] Please see the appendix Figure 1 To be continued Figure 10 The installation method and working principle of this invention are as follows:

[0058] Select a cover plate 201 of appropriate size according to the outer diameter of the pipe pile, place the cover plate 201 at the opening of the static pressure pile and match it to cover the top of the pipe pile, so that the insert 202 is inserted into the pipe pile.

[0059] Rotating the handle 102 moves the pressure cylinder 1 downwards via the thread, applying downward pressure to the bottom of the pressure rods 9 of several sets of pressure adjustment components. This causes the pressure rods 9 to rotate relative to the second mounting frame 8 within the through hole 801. Specifically, the upper end of the pressure rod 9 rotates downwards, while the lower end drives the pressure block 7 to rotate upwards, thus pressing the pressure block 7 against the inner wall of the pipe pile. By having several pressure blocks 7 circumferentially press against the inner wall of the pipe pile, the cover plate 201 is locked onto the pipe pile, achieving the purpose of opening protection.

[0060] At night, the lights inside the transparent cavity can provide illumination and warning, further enhancing the protection of the opening.

[0061] During disassembly, rotate the top pressure cylinder 1 upward to disengage it from the pressure rods 9 of several sets of top pressure adjustment components, and disengage several top pressure blocks 7 from the inner wall of the pipe pile.

[0062] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
