An adjustable portable pile hole protection device

Abstract

This invention provides an adjustable portable pile hole protection device, relating to the field of building construction technology. It includes a support plate with an adjustable structure around its perimeter. The adjustable structure includes inner grooves, multiple of which are formed around the support plate. A rotating component is rotatably installed inside each inner groove. By configuring the support plate, inner grooves, rotating component, ball-head hinge seat, ball-head hinge head, and fixed support legs, during construction, a standardized protection platform is first placed at the pile hole to form a basic protection base. The rotating component can rotate within the inner grooves, causing the fixed support legs to unfold or retract to achieve initial angle adaptation. Then, through the universal hinge structure of the ball-head hinge seat and ball-head hinge head, the fixed support legs deflect at multiple angles, forming an inverted funnel-shaped cover over the pile hole. This allows for rapid matching of the initial protection requirements of different pile diameters, effectively preventing personnel from accidentally entering open pile hole areas and solving the problems of poor adaptability and the risk of falls associated with traditional pile hole protection.

Description

Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to an adjustable portable pile hole protection device. Background Technology

[0002] In various construction projects, bridge projects, and municipal infrastructure construction, pile foundation construction is a crucial link. However, the construction process is often accompanied by many safety hazards. During the period from the formation of the pile hole to the pouring of concrete, the pile hole is still in an open state. With frequent daily personnel movement at the construction site, the open pile hole is like a series of "traps". Without effective safety protection, it is easy for people to fall in accidentally, causing serious injuries and property damage.

[0003] To address the protection issues of piles with different diameters during pile foundation construction, we have developed a highly portable, widely applicable, safe, and reliable pile hole protection device. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides an adjustable portable pile hole protection device.

[0005] An adjustable portable pile hole protection device includes a support plate.

[0006] Preferably, the support plate is provided with an adjustable structure around its periphery. The adjustable structure includes an inner groove, and multiple inner grooves are formed around the support plate. A rotating component is rotatably installed inside the inner groove. Ball joint hinge seats are symmetrically fixedly installed on the side wall of the rotating component. A ball joint hinge head is hinged to the inner side of the ball joint hinge seat. A fixed support leg is fixedly installed on the side wall of the ball joint hinge head.

[0007] Preferably, the fixed support leg has a sliding groove on its inner side, and a sliding column is slidably installed inside the sliding groove. A threaded groove is provided through the inner wall of the sliding groove. The rotating component can rotate in the inner groove, driving the fixed support leg to unfold or retract, adapting to the initial adjustment needs of different pile diameters. The ball joint hinge seat and the ball joint hinge head are universally hinged, allowing the fixed support leg to deflect at multiple angles, so that the whole device forms an inverted funnel-shaped cover, covering the pile hole. The sliding column is a telescopic structure that can slide along the axial direction of the sliding groove, realizing multi-level adjustment of the support leg length, adapting to the switching of protection range from small pile diameter to large pile diameter. A screw is installed inside the threaded groove, and the sliding column is fixed inside the sliding groove by the screw.

[0008] Preferably, the upper end of the support plate is provided with a warning light, the lower end of the support plate is fixedly installed with a cylinder, the inner side of the cylinder is provided with a light source distance adjustment device, the lower end of the light source distance adjustment device is provided with a light source body, the lower end of the cylinder is provided with a prism group, the prism group is adapted to the light source body, and the warning light is an integrated sound and light warning light, fixedly installed on the top of the support plate, which can emit light and sound warnings simultaneously.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In this invention, by setting up a bearing plate, an inner groove, a rotating component, a ball-head hinge seat, a ball-head hinge head, and a fixed support leg, the standardized protective platform is first placed at the pile hole to form a basic protective base during construction. The rotating component can rotate within the inner groove to drive the fixed support leg to unfold or retract to complete the initial angle adaptation. Then, through the universal hinge structure of the ball-head hinge seat and the ball-head hinge head, the fixed support leg can be deflected at multiple angles to form an inverted funnel-shaped cover above the pile hole. This allows for quick matching of the initial protection requirements of different pile diameters, effectively preventing on-site personnel from accidentally entering the open pile hole area, and solving the problems of poor adaptability and easy fall accidents caused by traditional pile hole protection.

[0011] In this invention, by setting a sliding groove, a sliding column, a threaded groove, and a screw on the inner side of the fixed support leg, the sliding column can slide freely along the axial direction of the sliding groove to achieve multi-level adjustment of the support leg length, flexibly adapting to the switching of protection range from small pile diameter to large pile diameter. After adjusting to the target length, the sliding column is locked and fixed by the screw in the threaded groove, thereby ensuring the stability of the support leg length and preventing the protective device from shifting and tipping over. This solves the problems of traditional protective devices having a single pile diameter adaptation and being easily damaged due to insecure fixing.

[0012] In this invention, by setting an integrated sound and light warning light at the upper end of the bearing plate, the warning light can simultaneously emit flashing light and sound prompts after the device is in place, so as to identify the location of the pile hole from both visual and auditory perspectives, reminding on-site personnel to actively avoid the pile hole area, thereby greatly improving the warning effect of the pile hole location and solving the problems of traditional pile hole protection relying only on simple markings, weak warning intensity, and easy negligence by personnel.

[0013] In this invention, a cylindrical body is fixed at the lower end of a support plate. Inside the cylindrical body, a light source distance adjustment device, a light source body, and a prism group are installed. The light source distance adjustment device can adjust the distance between the light source body and the prism group. After refraction by the prism group, a circular light spot of the corresponding size is projected to clearly show the actual range of the pile hole. This can enhance the protective identification of the pile hole range at night or in low light conditions, and solve the problem of blurred boundaries and easy formation of blind spots in traditional pile hole protection in dark environments.

[0014] In this invention, the rotating and modular design of the bearing plate, inner groove, rotating component, fixed support leg, and sliding column allows the rotating component to rotate within the inner groove, driving the fixed support leg to fold and retract. The sliding column can retract and store along the sliding groove, thus making the overall device small in size and light in weight, facilitating manual handling, site transfer, and stacking. This solves the problems of traditional pile hole protection devices being large in size, heavy and difficult to handle, cumbersome to disassemble and assemble, and having high transfer and storage costs.

[0020] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0021] Please see Figure 1 - Figure 4 The present invention provides an adjustable portable pile hole protection device, including a bearing plate 11.

[0022] The support plate 11 is provided with an adjustable structure around its perimeter. The adjustable structure includes an inner groove 12. Multiple inner grooves 12 are formed around the support plate 11. A rotating component 13 is rotatably installed inside the inner groove 12. A ball joint hinge seat 14 is symmetrically fixedly installed on the side wall of the rotating component 13. A ball joint hinge head 15 is hinged to the inner side of the ball joint hinge seat 14. A fixed support leg 16 is fixedly installed on the side wall of the ball joint hinge head 15.

[0023] By setting up a bearing plate 11, an inner groove 12, a rotating component 13, a ball-head hinge seat 14, a ball-head hinge head 15, and a fixed support leg 16, the standardized protective platform is first placed at the pile hole to form a basic protective base during construction. The rotating component 13 can rotate within the inner groove 12 to drive the fixed support leg 16 to unfold or retract to complete the initial angle adaptation. Then, through the universal hinge structure of the ball-head hinge seat 14 and the ball-head hinge head 15, the fixed support leg 16 can be deflected at multiple angles to form an inverted funnel-shaped cover above the pile hole. This allows for quick matching of the initial protection requirements of different pile diameters, effectively preventing on-site personnel from accidentally entering the open pile hole area, and solving the problem of poor adaptability of traditional pile hole protection and the risk of personnel falling.

[0024] Through the rotatable and modular design of the bearing plate 11, inner groove 12, rotating part 13, fixed support leg 16, and sliding column 18, the rotating part 13 can rotate in the inner groove 12 to drive the fixed support leg 16 to fold and retract, and the sliding column 18 can retract and store along the sliding groove 17. This makes the overall size of the device small and the weight light, which is convenient for manual handling, site transfer and stacking. It solves the problems of traditional pile hole protection devices being large, heavy and difficult to handle, cumbersome to disassemble and assemble, and having high transfer and storage costs.

[0025] The fixed support leg 16 has a sliding groove 17 on its inner side, and a sliding column 18 is slidably installed inside the sliding groove 17. A threaded groove 19 is provided through the inner wall of the sliding groove 17. The rotating part 13 can rotate in the inner groove 12, which drives the fixed support leg 16 to unfold or retract, adapting to the initial adjustment needs of different pile diameters. The ball joint hinge seat 14 and the ball joint hinge head 15 are universal joint structures, which can enable the fixed support leg 16 to deflect at multiple angles, so that the whole device forms an inverted funnel-shaped cover, which covers the pile hole. The sliding column 18 is a telescopic structure that can slide along the axial direction of the sliding groove 17 to realize multi-level adjustment of the support leg length, adapting to the switching of the protection range from small pile diameter to large pile diameter. A screw 21 is installed inside the threaded groove 19, and the sliding column 18 is fixed inside the sliding groove 17 by the screw 21.

[0026] By setting a sliding groove 17, a sliding column 18, a threaded groove 19, and a screw 21 on the inner side of the fixed support leg 16, the sliding column 18 can slide freely along the axial direction of the sliding groove 17 to achieve multi-level adjustment of the support leg length, flexibly adapting to the switching of protection range from small pile diameter to large pile diameter. After adjusting to the target length, the sliding column 18 is locked and fixed by the screw 21 in the threaded groove 19, thereby ensuring the stability of the support leg length and preventing the protective device from shifting and tipping over. This solves the problems of traditional protective devices having a single pile diameter adaptation and being easily damaged due to insecure fixing.

[0027] The upper end of the support plate 11 is provided with a warning light 22, and the lower end of the support plate 11 is fixedly installed with a cylinder 23. The inner side of the cylinder 23 is provided with a light source distance adjustment device 24, the lower end of the light source distance adjustment device 24 is provided with a light source body 25, and the lower end of the cylinder 23 is provided with a prism group 26. The prism group 26 is adapted to the light source body 25. The warning light 22 is an integrated sound and light warning light 22, which is fixedly installed on the top of the support plate 11 and can emit light and sound warnings simultaneously.

[0028] By installing an integrated sound and light warning light 22 at the upper end of the bearing plate 11, the warning light 22 can simultaneously emit flashing light and sound prompts after the device is in place, so as to identify the location of the pile hole from both visual and auditory perspectives, reminding on-site personnel to actively avoid the pile hole area, thereby greatly improving the warning effect of the pile hole location and solving the problem that traditional pile hole protection relies only on simple markings, has weak warning force, and is easily overlooked by personnel.

[0029] By fixing a cylinder 23 at the lower end of the bearing plate 11, a light source distance adjustment device 24, a light source body 25, and a prism group 26 are installed inside the cylinder 23. The light source distance adjustment device 24 can adjust the distance between the light source body 25 and the prism group 26. After being refracted by the prism group 26, a circular light spot of the corresponding size is projected to clearly show the actual range of the pile hole. This can enhance the protection and identification of the pile hole range at night or in low light conditions, and solve the problem that traditional pile hole protection has blurred boundaries and is prone to forming blind spots in dark environments.

[0030] Working principle:

[0031] During construction, the standardized protective platform is first placed at the pile hole. A hole inspection opening is reserved in the middle of the platform. After the hole inspection is completed, a cover plate can be placed on top to form the foundation protection base for the pile hole. A rotating component 13 is installed in the groove 12 around the bearing plate 11. The rotating component 13 can rotate within the groove 12, driving the fixed support leg 16 fixed on it to expand or retract synchronously, completing the initial angle adaptation for protection of different pile diameters and quickly matching the approximate size range of the pile hole. The side wall of the rotating component 13 forms a universal hinge structure with the ball head hinge seat 14 and the ball head hinge head 15. This structure allows the fixed support leg 16 to deflect at multiple angles in any direction, allowing the entire device to naturally form an inverted funnel-shaped cover, covering the open pile hole and preventing personnel from accidentally entering the pile hole area. A sliding groove 17 is opened on the inner side of the fixed support leg 16. The sliding column 18 in the sliding groove 17 is a telescopic structure that can slide freely along the axis of the sliding groove 17 to realize the adjustment of the support leg length and flexibly adapt to the switching of protection range from small pile diameter to large pile diameter. After adjusting to the target length, the sliding column 18 is locked and fixed by the screw 21 in the threaded groove 19 to ensure the stability of the support leg length and prevent the protective device from shifting. An integrated sound and light warning light 22 is installed on the top of the bearing plate 11. After the device is in place, it can be powered on. The warning light 22 will emit flashing light and sound prompts simultaneously, visually and audibly identifying the location of the pile hole and reminding on-site personnel to avoid it and avoid the risk of falling. The lower end of the bearing plate 11 is fixed to the cylinder 23. The cylinder 23 is equipped with a light source distance adjustment device 24 (existing technology, with distance adjustment function of the light source body 25). Its lower end is connected to the light source body 25. The bottom end of the cylinder 23 is equipped with a prism group 26 adapted to the light source body 25. The distance between the light source body 25 and the prism group 26 can be adjusted by the light source distance adjustment device 24. After being refracted by the prism group 26, a circular light spot of the corresponding size is projected, clearly showing the actual range of the pile hole and enhancing the protective identification in night or low light conditions.
