Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a protective device for PHC pipe piles. Background Art

[0002] PHC pipe pile is the abbreviation of prestressed high-strength concrete pipe pile. It is an important pile foundation building material and is widely used in pile foundation support for building foundations, bridges, roads and other projects.

[0003] For example, a Chinese patent discloses a protective device for PHC pile cutting, patent number: CN209958363U, through a cover plate, a central guide column and a sleeve, the top end of the central guide column and the top end of the sleeve are connected to the bottom surface of the cover plate, the central guide column and the sleeve are coaxial, and a sleeve cavity for sleeve-fitting the top wall of the PHC pile is formed between the central guide column and the sleeve. When the protective device for PHC pile cutting is installed on the PHC pile, the cover plate covers the top surface of the PHC pile, the central guide column is inserted into the pile core of the PHC pile, and the sleeve is sleeved on the outer wall of the PHC pile, so that the top side wall of the PHC pile is inserted into the sleeve cavity. Therefore, the protective device for PHC pile cutting is simple to make, easy to use, and can be used to prevent substances (such as soil, muddy water, etc.) from falling into the pile core of the PHC pile to ensure that the inside of the pile core is clean.

[0004] However, during the implementation of the above technical solution, it was found that there are at least the following technical problems: as mentioned above, when the two ends are impacted, the device cannot mitigate the impact, which may cause the two ends to rupture and the PHC piles to break. In severe cases, the PHC piles may be unusable and wasteful. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the deficiencies in the prior art, the utility model provides a protective device for PHC pipe piles to solve the technical problem that when both ends are impacted, the device cannot mitigate the impact, which may cause the two ends to rupture and the PHC pipe pile to break. In severe cases, the PHC pipe pile may be unusable and wasteful.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A protective device for a PHC pipe pile comprises a shell, a slide plate is slidably mounted on the side wall of the shell, a telescopic block is fixedly mounted on the side of the shell away from the slide plate, a screw rod is threadedly mounted inside the telescopic block, a protective mechanism is fixedly mounted inside the shell, the protective mechanism comprises a sleeve, and a mounting ring is fixedly mounted inside the sleeve.

[0010] Preferably, a spring is fixedly mounted on one end of the mounting ring away from the sleeve, and a damping rod is sleeved inside the spring.

[0011] Preferably, a connecting ring is fixedly mounted on one end of the spring away from the mounting ring, and a threaded rod is rotatably mounted inside the sleeve.

[0012] Preferably, a connecting column is threadedly mounted on the side wall of the threaded rod, and a first connecting rod is rotatably mounted on the side wall of the connecting column.

[0013] Preferably, a mounting rod is rotatably mounted on the side wall of the first connecting rod, and a second connecting rod is rotatably mounted on the side wall of the mounting rod.

[0014] Preferably, a support plate is rotatably mounted on the side wall of the second connecting rod, and a cross plate is slidably mounted on the side wall of the support plate.

[0015] (III) Beneficial effects

[0016] 1. By rotating the threaded rod clockwise, the threaded rod rotates the connecting column close to the cross plate. When the cross plate moves from back to front, it drives the abutment plate to move from bottom to top along the side wall of the cross plate. When the abutment plate contacts the inner wall of the PHC pile, the PHC pile is abutted to fix the PHC pile. When a collision occurs, the PHC pile squeezes the connecting ring, and the connecting ring moves from back to front. The connecting ring forces the spring and the damping rod to contract, slowing down the impact force and preventing the PHC pile from being damaged due to the impact, thereby achieving the function of protecting the PHC pile.

[0017] 2. Through the cooperation between the telescopic block and the screw rod, when the PHC pile is shorter, the screw rod is rotated counterclockwise, and the screw rod rotates in the internal thread of the telescopic block to shrink the telescopic block to a length suitable for the PHC pile, thereby achieving the function of adapting to PHC piles of different lengths.

[0025] The embodiment of the present application provides a protective device for PHC piles, which effectively solves the problem that when both ends are impacted, the device cannot reduce the impact, which may cause the two ends to rupture and the PHC pile to break. In severe cases, the PHC pile may be unusable and wasteful. By rotating the threaded rod clockwise, the threaded rod rotates the connecting column close to the cross plate. When the cross plate moves from back to front, it drives the abutment plate to move from bottom to top along the side wall of the cross plate. When the abutment plate contacts the inner wall of the PHC pile, the PHC pile is abutted to fix the PHC pile. When a collision occurs, the PHC pile squeezes the connecting ring, and the connecting ring moves from back to front. The connecting ring forces the spring and the damping rod to contract, reduce the impact force, and prevent the PHC pile from being damaged by the impact, thereby achieving the function of protecting the PHC pile. Through the cooperation of the telescopic block and the screw rod, when the PHC pile is shorter, the screw rod is rotated counterclockwise, and the screw rod rotates in the thread inside the telescopic block to shrink the telescopic block to a length suitable for the PHC pile, thereby achieving the function of adapting to PHC piles of different lengths.

[0026] Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that when the two ends are impacted, the device cannot mitigate the impact, which may cause the two ends to rupture, resulting in the PHC pile being broken, and in severe cases, the PHC pile may be unusable and wasteful. The overall idea is as follows:

[0028] A protective device for a PHC pipe pile comprises a shell 11. A slide plate 12 is slidably mounted on the side wall of the shell 11 to facilitate lifting the device.

[0029] A telescopic block 13 is fixedly installed on one side of the shell 11 away from the slide plate 12, and a screw rod 14 is installed on the internal thread of the telescopic block 13. Through the cooperation between the telescopic block 13 and the screw rod 14, when the PHC pile is shorter, the screw rod 14 is rotated counterclockwise, and the screw rod 14 rotates on the internal thread of the telescopic block 13 to shrink the telescopic block 13 to a length suitable for the PHC pile, thereby achieving the function of adapting to PHC piles of different lengths.

[0030] A protective mechanism is fixedly installed inside the housing 11, and the protective mechanism includes a sleeve 15, a mounting ring 16 is fixedly installed inside the sleeve 15, a spring 17 is fixedly installed on one end of the mounting ring 16 away from the sleeve 15, a damping rod is sleeved inside the spring 17, and a connecting ring 18 is fixedly installed on one end of the spring 17 away from the mounting ring 16, a threaded rod 21 is rotatably installed inside the sleeve 15, a connecting column 22 is threadedly installed on the side wall of the threaded rod 21, a first connecting rod 23 is rotatably installed on the side wall of the connecting column 22, a mounting rod 24 is rotatably installed on the side wall of the first connecting rod 23, a second connecting rod 25 is rotatably installed on the side wall of the mounting rod 24, a backing plate 26 is rotatably installed on the side wall of the second connecting rod 25, a cross plate 27 is slidably installed on the side wall of the backing plate 26, and the cross plate 27 is fixed inside the sleeve 15 The cross plate 27 is threadedly installed with the side wall of the threaded rod 21, the damping rod is fixedly installed with the mounting ring 16, and the end of the damping rod away from the mounting ring 16 is fixedly installed with the connecting ring 18. By rotating the threaded rod 21 clockwise, the threaded rod 21 rotates the connecting column 22 close to the cross plate 27. When the cross plate 27 moves from back to front, it drives the abutment plate 26 to move from bottom to top along the side wall of the cross plate 27. When the abutment plate 26 contacts the inner wall of the PHC pile, the PHC pile is abutted to fix the PHC pile. When a collision occurs, the PHC pile squeezes the connecting ring 18, and the connecting ring 18 moves from back to front. The connecting ring 18 forces the spring 17 and the damping rod to contract, slowing down the impact force and preventing the PHC pile from being damaged due to the impact, thereby achieving the function of protecting the PHC pile.

[0031] In view of the problems existing in the prior art, the utility model provides a protective device for PHC piles. By rotating the threaded rod 21 clockwise, the threaded rod 21 rotates the connecting column 22 close to the cross plate 27. When the cross plate 27 moves from back to front, it drives the abutment plate 26 to move from bottom to top along the side wall of the cross plate 27. When the abutment plate 26 contacts the inner wall of the PHC pile, the PHC pile is abutted to fix the PHC pile. When a collision occurs, the PHC pile squeezes the connecting ring 18, and the connecting ring 18 moves from back to front. The connecting ring 18 forces the spring 17 and the damping rod to contract, slowing down the impact force and preventing the PHC pile from being damaged due to the impact, thereby achieving the function of protecting the PHC pile. Through the cooperation of the telescopic block 13 and the screw rod 14, when the PHC pile is shorter, the screw rod 14 is rotated counterclockwise, and the screw rod 14 rotates in the internal thread of the telescopic block 13 to shrink the telescopic block 13 to a length suitable for the PHC pile, thereby achieving the function of adapting to PHC piles of different lengths.

[0032] Working principle:

[0033] The first step is to adjust the length of the telescopic block 13 according to the length of the PHC pile. When the PHC pile is shorter, the screw rod 14 is rotated counterclockwise, and the screw rod 14 rotates in the internal thread of the telescopic block 13 to shrink the telescopic block 13 to a length suitable for the PHC pile, thereby achieving the function of adapting to PHC piles of different lengths.

[0034] The second step is to push the slide plate 12 from left to right, and then rotate the threaded rod 21 clockwise. The threaded rod 21 rotates the connecting column 22 close to the cross plate 27. When the cross plate 27 moves from back to front, it drives the abutment plate 26 to move from bottom to top along the side wall of the cross plate 27. When the abutment plate 26 contacts the inner wall of the PHC pile, the PHC pile is abutted to fix the PHC pile. When a collision occurs, the PHC pile squeezes the connecting ring 18, and the connecting ring 18 moves from back to front. The connecting ring 18 forces the spring 17 and the damping rod to contract, reduce the impact force, and prevent the PHC pile from being damaged due to the impact, thereby achieving the function of protecting the PHC pile.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
