Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection, in particular to an adjustable fixing device for engineering pile foundation detection. Background Technique

[0002] With the rapid development of society, high-rise buildings, bridges and other infrastructure projects all adopt the foundation form of cast-in-place piles to improve the stability of buildings. However, due to various construction factors, quality accidents such as broken piles and interlayers often occur in cast-in-place piles. Therefore, it is necessary to determine the location of defects, and the pile foundation needs to be fixed during the pile foundation detection process.

[0003] An adjustable fixing device for engineering pile foundation detection disclosed in the patent application No. 202222034389.4 drives the clamping block to move out of the clamping groove by pulling the handle, and then moves the fixing rod through the pull plate to drive the arc plate to move, so that the distance between the two arc plates can be adjusted according to piles of different sizes, facilitating the fixing of piles of various sizes.

[0004] When the pile foundation is fixed and clamped in the above-mentioned comparative patent, it is necessary to operate the arc plates separately from both sides, which is rather troublesome and thus urgently needs to be solved. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Please refer to Figures 1 to 3 , the present invention provides a technical solution: an adjustable fixing device for engineering pile detection, including a fixed clamping plate 1 and a movable clamping plate 2. Two guide rods 3 are fixedly connected to the side of the movable clamping plate 2 close to the fixed clamping plate 1. The ends of the guide rods 3 are movably inserted through the fixed clamping plate 1. A moving strip 4 is fixedly connected to the ends of the two guide rods 3. The guide rods 3 are in a round rod shape and are symmetrically distributed on the movable clamping plate 2. A screw rod 5 is rotatably inserted into the side wall of the fixed clamping plate 1. The moving strip 4 is threadedly sleeved on the screw rod 5. A hand wheel 6 is fixedly connected to the end of the screw rod 5.

[0024] Lean the pile against the arc-shaped inner wall of the fixed clamping plate 1, and then rotate the hand wheel 6 to drive the screw rod 5 to rotate. The screw rod 5 drives the moving strip 4 to linearly displace. The moving strip 4 drives the movable clamping plate 2 to linearly displace through the guide rods 3, so that the movable clamping plate 2 contacts the surface of the pile, achieving the purpose of fixed clamping of the pile. This method only requires one-sided operation, which is more convenient. And during the clamping process, the movable clamping plate 2 is always in a self-locking state and can maintain its current position; this device can be adjusted according to piles of different sizes, facilitating the fixation of piles of various sizes, with a wider scope of application, and can achieve rapid fixed clamping of piles, thereby improving work efficiency.

[0025] A bracket 7 is fixedly connected to the bottom of the fixed clamping plate 1. A bottom plate 9 is provided below the fixed clamping plate 1. Two guide bars 8 are fixedly connected to the top of the bottom plate 9. The upper ends of the guide bars 8 are movably inserted through the bracket 7.

[0026] The guide bars 8 provide a stable guiding path, ensuring that the bracket 7 will not deviate from the track during the movement, thereby maintaining the accuracy and stability of the clamping between the fixed clamping plate 1 and the movable clamping plate 2.

[0027] A rack 10 is fixedly connected to the side wall of the bracket 7. A support 12 is fixedly connected to the top of the bottom plate 9. A rotating shaft 16 is rotatably inserted into the support 12. A gear 11 is fixedly connected to one end of the rotating shaft 16. The gear 11 is engaged with the rack 10.

[0028] The other end of the rotating shaft 16 penetrates through the support 12 and is fixedly connected to a worm gear 13. A knob 15 is movably inserted into the support 12. A worm 14 is fixedly connected to the end of the knob 15. The worm 14 is in meshing contact with the worm gear 13.

[0029] Rotate the knob 15 to drive the worm 14 to rotate. The worm 14 drives the worm gear 13 to rotate. The worm gear 13 drives the gear 11 to rotate through the rotating shaft 16. The gear 11 drives the rack 10 to move vertically. The rack 10 drives the fixed clamping plate 1 to move vertically through the bracket 7, so as to adjust the vertical clamping position of the fixed clamping plate 1 and the movable clamping plate 2, and better fix the foundation pile; ensuring the flexibility and reliability of the clamping system and strong adaptability.

[0030] The opposite sides of the movable clamping plate 2 and the fixed clamping plate 1 are both arc-shaped structures, which are adapted to the cylindrical foundation pile. The arc-shaped structure can ensure that the movable clamping plate 2, the fixed clamping plate 1 and the surface of the foundation pile are in close contact, improving the stability and reliability of clamping and ensuring the clamping effect.
