DETAILED DESCRIPTION

[0022] The utility model is further described in detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a device for detecting the verticality of a pile foundation of a building, comprising a fixed bracket 1, the fixed bracket 1 is arranged in an "L" shape, a handle 2 is fixedly installed on the left side of the fixed bracket 1, a detection component 3 is fixedly installed on the front side of the fixed bracket 1, a perspective window 4 is fixedly installed inside the detection component 3, and a fixed component 5 arranged vertically to the detection component 3 is movably installed inside the fixed bracket 1.

[0024] By setting the detection component 3 on the front side of the fixed bracket 1, the fixed bracket 1 is set outside the pile foundation, and the perspective window 4 is set on the front side of the detection component 3, the inside of the detection component 3 can be seen through the perspective window 4, and the verticality of the pile foundation is detected by the internal parts of the detection component 3 being perpendicular to the ground under the gravity, and the readings in the detection component 3 can be checked through the perspective window 4, thereby reducing the influence of external wind and shaking compared with the method of measuring with a rope hanging a plumb bob, thereby reducing the influence on the detection. At the same time, the fixed bracket 1 can be operated by the fixing component 5 inside it to make the fixing component 5 move forward and backward along the fixed bracket 1 to fix the pile foundation to the inner side of the fixed bracket 1 and the fixing component 5, so as to facilitate the fixation of different pile foundations without having to hold it in hand all the time, which is convenient for detection and use.

[0025] like Figure 2 and Figure 3 As shown, the detection component 3 includes a windproof box body 31 and a cover plate 32 fixedly installed on the front side of the windproof box body 31, a fixed shaft 33 is fixedly connected to the upper part of the interior of the windproof box body 31, a movable rod 34 is movably sleeved on the outside of the fixed shaft 33, a counterweight 35 is movably clamped on the bottom of the movable rod 34, a fixing bolt 36 penetrating the counterweight 35 is threadedly connected to the lower part of the front side of the movable rod 34, a pointer 37 is arranged at the lower inner side of the movable rod 34, and a dial 38 is fixedly installed on the rear side of the interior of the windproof box body 31.

[0026] The movable rod 34 located inside the windproof box 31 is rotated along the fixed axis 33 under the influence of the gravity of the counterweight 35 at its bottom. The counterweight 35 drives the fixed axis 33 to move perpendicular to the ground due to gravity. The verticality of the pile foundation is detected by observing the angle between the pointer 37 on the inside of the movable rod 34 and the dial 38 in the windproof box 31. The use of the windproof box 31 in conjunction with the movable rod 34 avoids the influence of external wind, reduces the impact of detection, and ensures the accuracy of detection.

[0027] like Figure 4 and Figure 5 As shown, the fixing assembly 5 includes a threaded rod 51, which is rotatably installed inside the fixed card frame 1, and the front side of the threaded rod 51 is fixedly connected to a handwheel 52 located outside the fixed card frame 1, and the handwheel 52 and the detection assembly 3 are arranged on the same side, and the external thread of the threaded rod 51 is connected to a sliding block 53 located in the fixed card frame 1, and the rear side of the sliding block 53 is fixedly connected to a connecting rod 54 that penetrates the fixed card frame 1, and the rear side of the connecting rod 54 is fixedly connected to a movable splint 55.

[0028] The threaded rod 51 in the fixed bracket 1 is driven to rotate by turning the hand wheel 52, and the sliding block 53 is driven to slide forward along the threaded rod 51 by the rotation of the threaded rod 51. The connecting rod 54 is driven to slide forward by the sliding of the hand wheel 52, so that the movable clamping plate 55 and the supporting plate 56 connected to the connecting rod 54 move forward, so that the pile foundation is located between the fixed bracket 1 and the movable clamping plate 55 and is clamped on the outside of the pile foundation for fixation, thereby facilitating the fixation of pile foundations of different sizes without having to hold it in hand all the time, thereby improving the convenience of use.

[0029] like Figure 3 As shown, the pointer 37 is adapted to the position of the scale 38 .

[0030] The pointer 37 is matched with the scale plate 38 , and the verticality of the pile foundation is detected by the direction of the pointer 37 on the scale plate 38 .

[0031] like Figure 2 As shown, the four corners of the front side of the cover plate 32 are movably mounted with fixing bolts 39 , and the fixing bolts 39 are threadedly connected to the interior of the windproof box body 31 .

[0032] The cover plate 32 is installed outside the windproof box body 31 by means of fixing bolts 39 to seal the windproof box body 31 and reduce the influence of the external environment on it.

[0033] like Figure 2 As shown, the perspective window 4 is made of transparent plastic material.

[0034] The perspective window 4 is made of transparent plastic material, which is not easily damaged and is convenient for maintenance.

[0035] like Figure 4 As shown, the inner sides of the fixed bracket 1 and the movable clamping plate 55 are both provided with an anti-slip coating 6 , and the width of the movable clamping plate 55 is adapted to the fixed bracket 1 .

[0036] The provision of the anti-slip coating 6 improves the stability when the movable clamping plate 55 and the fixed clamping frame 1 clamp and fix the pile foundation.

[0037] like Figure 4 As shown, a support plate 56 is fixedly connected to the bottom of the movable clamping plate 55 .

[0038] The support plate 56 is provided to increase the force range when clamping the pile foundation, thereby ensuring stability.

[0039] The following is a detailed description of the working principle of the pile foundation verticality detection device of the building.

[0040] like Figures 1 to 5 As shown, the fixed bracket 1 is clamped outside the pile foundation from one side of its opening, and the threaded rod 51 located in the fixed bracket 1 is driven to rotate by turning the hand wheel 52, and the sliding block 53 is driven to slide forward along the threaded rod 51 by the rotation of the threaded rod 51, and the connecting rod 54 is driven to slide forward by the sliding of the hand wheel 52, so that the movable clamping plate 55 and the supporting plate 56 connected to the connecting rod 54 move forward, so that the pile foundation is located between the fixed bracket 1 and the movable clamping plate 55 and is clamped on the outside of the pile foundation for fixing, and the fixed bracket 1 is fixed outside the pile foundation so that the detection component 3 is parallel to the pile foundation, and the movable rod 34 located inside the windproof box 31 is rotated along the fixed shaft 33 under the influence of the gravity of the counterweight 35 at its bottom, and the fixed shaft 33 is driven by the counterweight 35 to move perpendicular to the ground by gravity, and the verticality of the pile foundation is detected by observing the angle between the pointer 37 on the inner side of the movable rod 34 and the dial 38 in the windproof box 31.
