Description

Technical Field

[0001] This utility model relates to the technical field of verticality detection devices, and in particular to a verticality detection device for prestressed pipe piles. Background Technology

[0002] Prestressed concrete pipe piles are a type of pile foundation structure widely used in building construction. They are typically prefabricated in a precast component factory and then transported to the construction site for installation. These pipe piles are driven into the soil using a pile driver, and a foundation beam (slab) is poured on top of them. Verticality testing of prestressed concrete pipe piles is crucial during installation. The purpose of verticality testing is to ensure that the pipe piles are installed accurately according to design requirements, guaranteeing the stability and safety of the structure.

[0003] When testing verticality, the plumb line method is generally used, which is one of the most common methods on site. During operation, a plumb line (usually called a plumb bob or lead weight) is suspended at the top center of the pipe pile. The deviation between the plumb line and the side of the pipe pile is then observed. If the deviation is within the allowable range, the verticality of the pipe pile is considered to meet the requirements. This method is simple and easy to implement, but its accuracy is greatly affected by human factors and environmental conditions. Utility Model Content

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 5 As shown, the prestressed concrete pipe pile verticality testing device proposed in this utility model includes two connectors sleeved on the pipe pile. Each connector includes a connecting seat 1, with an arc-shaped plate 101 rotatably mounted at both ends of the connecting seat 1. The two arc-shaped plates 101 are fixedly connected by fastening bolts 102. When testing the verticality of the pipe pile, first remove the fastening bolts 102, then sleeve the arc-shaped plates 101 onto the pipe pile, and then fix the two arc-shaped plates 101 onto the pipe pile using the fastening bolts 102. This fixes the arc-shaped plates 101 onto the pipe pile.

[0023] Among them, the arc-shaped plates 101 are paired, and a positioning rod 3 is rotatably positioned between the two corresponding arc-shaped plates 101. The positioning rod 3 is a telescopic rod, that is, the length of the positioning rod 3 can be adjusted. The upper and lower connecting parts are connected by the positioning rod 3 for easy storage. When installing the two connecting parts, the distance between the two connecting parts along the vertical direction needs to be maintained at a predetermined length.

[0024] This embodiment also includes a detection component 2 installed between the two connectors. The detection component includes a telescopic connection assembly, a transmission amplification assembly, and an indicator assembly that are rotatably installed between the two connectors. The telescopic connection assembly extends and retracts when the two connectors are misaligned. The transmission amplification assembly detects the amount of extension and retraction of the connection assembly and amplifies the amount of extension and retraction when the connection assembly extends and retracts. The indicator assembly indicates the tilt angle between the two connectors.

[0025] Furthermore, the connecting assembly includes a connecting rod 201 rotatably mounted on one of the connecting seats 1, a first sealing head 202 fixedly mounted on the connecting rod 201, and a first oil drum 203 slidably mounted on the first sealing head 202, the first sealing head 202 being located inside the first oil drum 203. A connecting block 208 is rotatably mounted on the other connecting seat 1, and support rods 207 are fixedly mounted on both ends of the connecting block 208. The support rods 207 are fixedly connected to the first oil drum 203 through a transmission amplification assembly. When the distance between the two connecting parts remains constant, if the pipe pile has an inclination problem, misalignment will occur between the two connecting parts. This will cause the connecting rod 201 and the support rod 207 to rotate on the connecting seat 1. While the vertical distance between the two connecting seats 1 remains constant, the linear distance between the two connecting seats 1 will change. When the linear distance between the two connecting seats 1 changes, the first sealing head 202 will slide inside the first oil drum 203 to adapt to the change in the linear distance between the two connecting seats 1.

[0026] Furthermore, the transmission amplification assembly includes a second oil tank 205 fixedly mounted on two support rods 207. A second sealing head 206 is slidably installed inside the second oil tank 205. The upper and lower ends of the first oil tank 203 and the second oil tank 205 are connected by steel pipes 204. The inner diameter of the second oil tank 205 is smaller than the inner diameter of the first oil tank 203. The first oil tank 203, the second oil tank 205, and the steel pipes 204 are all filled with hydraulic oil 212. A sealing treatment is provided between the first sealing head 202 and the first oil tank 203, and a sealing treatment is provided between the second sealing head 206 and the second oil tank 205. When the first sealing head 202 slides inside the first oil drum 203, the hydraulic oil 212 inside the first oil drum 203 will be squeezed into the second oil drum 205, and the second sealing head 206 will move. Then, under the action of the second sealing head 206, the hydraulic oil inside the second oil drum 205 will be squeezed into the first oil drum 203. Since the inner diameter of the second oil drum 205 is smaller than the inner diameter of the first oil drum 203, the moving distance of the second sealing head 206 will be greater than the distance of one end of the first sealing head 202. Therefore, the inclination of the pipe pile can be judged based on the moving distance of the second sealing head 206. The greater the inclination of the pipe pile, the longer the moving distance of the second sealing head. Furthermore, due to the change in the inner diameter between the first oil drum 203 and the second oil drum 205, the inclination of the pipe pile can be reflected intuitively even when the inclination of the pipe pile is small, which is convenient for observation.

[0027] The indicating component includes a transmission rod 209 fixedly mounted on the second sealing head 206, a pointer 210 fixedly mounted on the transmission rod 209, and a scale 211 fixedly mounted on one of the support rods 207. When the second sealing head 206 moves, it will drive the transmission rod 209 to move, thereby causing the pointer 210 to move to one side of the scale 211. The inclination of the pipe pile can be determined by the reading indicated by the pointer 210 on the scale 211.

[0028] The working principle of this embodiment is as follows: When checking the verticality of the pipe pile, firstly, the fastening bolts 102 are removed, then the arc-shaped plate 101 is fitted onto the pipe pile, and then the two arc-shaped plates 101 are fixed to the pipe pile by the fastening bolts 102. When installing the two connectors, the distance between the two connectors along the vertical direction must be maintained at a predetermined length.

[0029] When the distance between the two connectors remains constant, if the pipe pile is tilted, the two connectors will be misaligned. This will cause the connecting rod 201 and the support rod 207 to rotate on the connecting seat 1. While the vertical distance between the two connecting seats 1 remains constant, the straight distance between the two connecting seats 1 will change. When the straight distance between the two connecting seats 1 changes, the first sealing head 202 will slide inside the first oil tank 203 to adapt to the change in the straight distance between the two connecting seats 1. When the first sealing head 202 slides inside the first oil drum 203, it will squeeze the hydraulic oil 212 inside the first oil drum 203 into the second oil drum 205, and drive the second sealing head 206 to move. Then, under the action of the second sealing head 206, the hydraulic oil inside the second oil drum 205 will be squeezed into the first oil drum 203. Since the inner diameter of the second oil drum 205 is smaller than the inner diameter of the first oil drum 203, the moving distance of the second sealing head 206 will be greater than the distance of one end of the first sealing head 202. Therefore, the inclination of the pipe pile can be judged based on the moving distance of the second sealing head 206. When the second sealing head 206 moves, it will drive the transmission rod 209 to move, which will cause the pointer 210 to move on one side of the scale 211. The inclination of the pipe pile can be judged by the reading indicated by the pointer 210 on the scale 211.

[0030] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
