Description

Technical Field

[0001] This utility model relates to the field of pile foundation positioning technology, and more specifically, to a pile foundation positioning and anti-deviation device for pile foundation engineering. Background Technology

[0002] Pile foundation engineering refers to the foundation engineering in building construction. By setting piles in the ground, the weight of the building is supported and the load is transferred. The main function of pile foundation engineering is to improve the bearing capacity and stability of the foundation and reduce the settlement and deformation of the building. In pile foundation engineering, different types of piles are usually used, such as precast piles and cast-in-place piles. In order to prevent the piles from shifting during installation, positioning and anti-deviation devices are required to ensure the stability of the pile foundation and prevent it from shifting.

[0003] Utility model patent CN222390486U discloses a pile foundation positioning and anti-deviation device for pile foundation engineering, which includes a first positioning and anti-deviation sleeve and a second positioning and anti-deviation sleeve to perform positioning and anti-deviation work on the pile foundation. Its shortcomings are: the first and second positioning and anti-deviation sleeves are a single integral structure, which cannot be applied to pile foundations of different thicknesses; secondly, when the first and second positioning and anti-deviation sleeves perform positioning and anti-deviation work on the pile foundation, the contact between the clamping pile sleeve and the pile foundation generates significant friction, which is not conducive to the lowering of the pile foundation. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a pile foundation positioning and anti-deviation device for pile foundation engineering that can solve the above problems.

[0005] A pile foundation positioning and anti-deviation device for pile foundation engineering includes a base, a positioning plate, a support plate, and an anti-deviation sleeve. The base is disposed at the top of the pile foundation pit and has a first through hole, the diameter of which is equal to or greater than the diameter of the pile foundation pit. The positioning plate is disposed on the top surface of the base and has a second through hole. Two support plates are disposed above the positioning plate and symmetrically arranged on both sides of the second through hole. Each support plate has an anti-deviation sleeve on the side near the second through hole. Each anti-deviation sleeve includes three anti-deviation plates, each connected to the support plate and whose distance from the support plate can be individually adjusted.

[0006] Furthermore, the anti-deviation sleeve includes a first anti-deviation plate and a second anti-deviation plate disposed on both sides of the first anti-deviation plate. A connecting plate is fixed to the side of the first anti-deviation plate near the support plate. The connecting plate is connected to the support plate and the distance between the connecting plate and the support plate is adjustable. The second anti-deviation plate is connected to the connecting plate and the distance between the connecting plate and the connecting plate is adjustable.

[0007] Furthermore, a first screw is rotatably provided on the side of the connecting plate near the support plate. The first screw passes through the support plate and is rotatably and axially telescopically connected to the support plate.

[0008] Furthermore, a first nut is fixed to the side of the support plate away from the connecting plate, and the first screw is screwed to the first nut.

[0009] Furthermore, a guide rod is fixed to the side of the connecting plate near the support plate, and the guide rod passes through the support plate and is horizontally slidably connected to the support plate.

[0010] Furthermore, a second screw is rotatably provided on the side of the second anti-deviation plate near the connecting plate. The second screw passes through the connecting plate and is rotatably and circumferentially connected to the connecting plate.

[0011] Furthermore, both the first anti-deviation plate and the second anti-deviation plate have horizontally formed mounting grooves on the side away from the connecting plate, and a plurality of ball bearings are arranged in the mounting grooves, with the axis of the ball bearings being horizontally arranged.

[0012] Furthermore, a telescopic rod is vertically provided at the bottom of the support plate, and the upper and lower ends of the telescopic rod are respectively connected to the support plate and the positioning plate.

[0013] Furthermore, a stud is vertically fixed to the top surface of the base, the positioning plate has a mounting hole, the positioning plate is sleeved on the stud, and a mounting nut is provided on the stud.

[0014] Furthermore, the edges of the positioning plates are all located inside the top edge of the base, the base is made of steel plate with a thickness of more than 10 cm, and the top edge of the base is fixed with lifting lugs.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The pile foundation positioning and anti-deviation device for pile foundation engineering in this utility model consists of three horizontally arranged anti-deviation plates. The three anti-deviation plates can clamp and prevent deviation at different points of the pile foundation, and each anti-deviation plate can be individually adjusted in distance from the support plate, so it can be applied to pile foundations of different thicknesses to perform positioning and anti-deviation work for the pile foundation.

[0017] The pile foundation positioning and anti-deviation device of this utility model has several rolling balls set on the side of the first and second anti-deviation plates away from the connecting plate. When positioning and preventing deviation of the pile foundation, the rolling balls are made to contact the pile foundation body. Since the rolling balls can rotate along the horizontal axis, the contact friction in the prior art can be replaced with rolling friction, which effectively reduces the friction force and is conducive to the lowering of the pile foundation body into the foundation pit.

[0025] 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.

[0026] like Figures 1-5As shown, the pile foundation positioning and anti-deviation device for pile foundation engineering in this embodiment includes a base 1, a positioning plate 3, a support plate 5, and an anti-deviation sleeve. The base 1 is set at the top of the pile foundation pit, and a first through hole 2 is opened in the middle of the base 1. The diameter of the first through hole 2 is equal to or greater than the diameter of the pile foundation pit. The positioning plate 3 is set on the top surface of the base 1. The positioning plate 3 is detachably connected to the base 1 and has a second through hole 4. The diameter of the second through hole 4 is equal to or greater than the diameter of the pile foundation pit. Two support plates 5 are set above the positioning plate 3 and are symmetrically arranged on both sides of the second through hole 4. An anti-deviation sleeve is set on the side of the support plate 5 near the second through hole 4. The anti-deviation sleeve includes three horizontally arranged anti-deviation plates. The anti-deviation plates are connected to the support plates 5 and the distance between each anti-deviation plate and the support plate 5 can be adjusted independently.

[0027] In this embodiment, the edges of the positioning plate 3 are all located inside the edge of the top surface of the base 1. A stud 16 is fixed to the top surface of the base 1. The positioning plate 3 has mounting holes that fit the stud 16. The positioning plate 3 is sleeved on the stud 16, and a mounting nut 17 is provided on the stud 16, thereby connecting the positioning plate 3 to the base 1. The base 1 can be a steel plate with a thickness of 10 cm or more, or a thicker concrete base 1 can be selected, so that the base 1 has sufficient mass to effectively prevent positional displacement during use. When the base 1 is a steel plate, a lifting lug 19 is welded to the edge of the top surface of the base 1; when the base 1 is a concrete structure, a lifting lug 19 is provided on the top surface of the base, and the lower end of the lifting lug 19 is embedded in the concrete structure to facilitate hoisting.

[0028] In this embodiment, the support plate 5 is positioned above the positioning plate 3, and a telescopic rod 15 is provided between the support plate 5 and the positioning plate 3. The upper and lower ends of the telescopic rod 15 are connected to the support plate 5 and the positioning plate 3 respectively, thereby supporting the support plate 5 and allowing the height of the support plate 5 to be adjusted. Specifically, the telescopic rod 15 can be an electric cylinder, a hydraulic cylinder, or a pneumatic cylinder.

[0029] In this embodiment, the anti-deviation sleeve is a partially enclosed structure composed of a first anti-deviation plate 6 and two second anti-deviation plates 7. The first anti-deviation plate 6 and the second anti-deviation plates 7 are arranged horizontally, with the two second anti-deviation plates 7 located on both sides of the first anti-deviation plate 6. A connecting plate 8 is fixed to the side of the first anti-deviation plate 6 near the support plate 5. A first screw 9 is rotatably mounted on the side of the connecting plate 8 near the support plate 5. The first screw 9 is horizontally positioned and passes through the support plate 5. A first nut 10 is fixed to the side of the support plate 5 away from the connecting plate 8. The first screw 9 and the first nut 10 are threadedly connected. By rotating the first screw 9, the distance between the connecting plate 8 and the support plate 5 can be adjusted, thereby realizing the adjustment of the distance between the first anti-deviation plate 6 and the support plate 5. Preferably, a guide rod 11 is fixedly mounted on the side of the connecting plate 8 near the support plate 5. The guide rod 11 is horizontally positioned and passes through the support plate 5, and the guide rod 11 is horizontally slidably connected to the support plate 5. By setting the guide rod 11, the angle of the connecting plate 8 does not deflect when it moves in the horizontal direction.

[0030] In this embodiment, two second anti-deviation plates 7 are disposed on both sides of the first anti-deviation plate 6. A second screw 12 is rotatably disposed on the side of the second anti-deviation plate 7 near the connecting plate 8. The second screw 12 is horizontally disposed and passes through the connecting plate 8. A second nut 18 is fixed on the side of the connecting plate 8 away from the second anti-deviation plate 7. The second screw 12 and the second nut 18 are threadedly connected. By rotating the second screw 12, the distance between the second anti-deviation plate 7 and the connecting plate 8 can be adjusted. By adjusting the distance between the connecting plate 8 and the support plate 5, and by adjusting the distance between the second anti-deviation plate 7 and the connecting plate 8, the distance between the second anti-deviation plate 7 and the support plate 5 can be adjusted.

[0031] In this embodiment, both the first anti-deviation plate 6 and the second anti-deviation plate 7 have horizontally formed mounting grooves 13 on the side away from the connecting plate 8. A plurality of ball bearings 14 are horizontally arranged within the mounting grooves 13, with the axes of the ball bearings 14 set horizontally. The first anti-deviation plate 6 and the second anti-deviation plate 7 can adopt an arc-shaped plate or a flat plate structure. When the first anti-deviation plate 6 and the second anti-deviation plate 7 adopt an arc-shaped plate structure, the axes of the ball bearings 14 are tangent to the arc. When the first anti-deviation plate 6 and the second anti-deviation plate 7 adopt a flat plate structure, the axes of the ball bearings 14 are parallel to the flat plate structure. By setting a plurality of ball bearings 14 on the side of the first anti-deviation plate 6 and the second anti-deviation plate 7 away from the connecting plate 8, the ball bearings 14 are brought into contact with the pile foundation body during the positioning and anti-deviation work of the pile foundation. Since the ball bearings 14 can rotate along the horizontal axis, the contact friction in the prior art can be replaced with rolling friction, effectively reducing friction and facilitating the lowering of the pile foundation body into the foundation pit. In practical applications, multiple mounting slots 13 can be set vertically on the first anti-deviation plate 6 and the second anti-deviation plate 7. The specific number of mounting slots 13 and balls 14 can be set according to the actual situation.

[0032] The working principle of the pile foundation positioning and anti-deviation device for pile foundation engineering in this embodiment is as follows:

[0033] In this embodiment, the pile foundation positioning and anti-deviation device for pile foundation engineering has a base 1 set at the top of the pile foundation pit. Due to its sufficient mass, it is not easy to move during use. The positioning plate 3 is detachably installed on the top of the base 1 via studs 16 and mounting nuts 17. A telescopic rod 15 is provided between the positioning plate 3 and the support plate 5, which can adjust the height of the support plate 5, thereby adjusting the height of the anti-deviation sleeve. By rotating the first screw 9, the distance between the connecting plate 8 and the support plate 5 can be adjusted, thereby adjusting the distance between the first anti-deviation plate 6 and the support plate 5. By rotating the second screw 12, the distance between the second anti-deviation plate 7 and the connecting plate 8 can be adjusted. By adjusting the distance between the connecting plate 8 and the support plate 5, and by adjusting the distance between the second anti-deviation plate 7 and the connecting plate 8, the distance between the second anti-deviation plate 7 and the support plate 5 can be adjusted, thus making it suitable for pile foundations of different thicknesses. By setting a number of balls 14 on the side of the first anti-deviation plate 6 and the second anti-deviation plate 7 away from the connecting plate 8, the balls 14 are made to contact the pile body when positioning and preventing deviation of the pile foundation. Since the balls 14 can rotate along the horizontal axis, the contact friction in the prior art can be replaced by rolling friction, which effectively reduces the friction force and is conducive to the lowering of the pile body into the foundation pit.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
