DETAILED DESCRIPTION

[0017] 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.

[0018] Example: Figures 1-4 As shown, this utility model provides a building foundation settlement detection device, including a support 1, an adjustment frame 2 fixedly mounted on the support 1, the adjustment frame 2 being firmly connected to the support 1 by welding to ensure that it will not loosen during adjustment, a lead screw 21 being rotatably mounted inside the adjustment frame 2, and a motor 22 being fixedly mounted on the upper surface of the adjustment frame 2 to ensure effective power transmission, and the output end of the motor 22 passing through the adjustment frame 2 and fixedly connected to the lead screw 21, the motor 22 being a stepper motor, capable of precisely controlling the rotation angle and speed, its output shaft being fixedly connected to the lead screw 21 via a coupling, a lifting frame 3 being threaded onto the outer surface of the lead screw 21, a slider 31 being fixedly mounted on one side of the lifting frame 3, and the slider 31 being engaged with the adjustment frame 2, the upper surface of the lifting frame 3 being fixedly mounted with a reinforcing tube 24, and the reinforcing tube 24 being further fixed to the upper surface of the lifting frame 3. The reinforcing tube 24 is threaded onto the outer surface of the lead screw 21. A limiting post 23 is symmetrically fixed inside the adjusting frame 2, and the limiting post 23 penetrates the lifting frame 3. A flat block 4 is fixed inside the lifting frame 3. When the measurement position needs to be adjusted, the motor 22 on the upper surface of the adjusting frame 2 is started. The output end of the motor 22 drives the lead screw 21 to rotate. Since the lifting frame 3 is threaded onto the outer surface of the lead screw 21, and the slider 31 on one side of the lifting frame 3 is engaged on the adjusting frame 2, and the limiting post 23 inside the adjusting frame 2 penetrates the lifting frame 3, the rotation of the lifting frame 3 is restricted, thus converting the rotation of the lead screw 21 into the linear lifting motion of the lifting frame 3. Simultaneously, the reinforcing tube 24 is threaded onto the outer surface of the lead screw 21 and fixed to the upper surface of the lifting frame 3, further enhancing the stability of the lifting frame 3 during the lifting process.

[0019] The upper surface of the plane block 4 is movably provided with a measuring column 41, which is made of high-precision stainless steel bar and has high surface smoothness, can freely slide in the plane block 4 without jamming, and is provided with a sliding groove 45. The outer surface of the measuring column 41 is symmetrically provided with a sliding strip 46 which is clamped in the corresponding sliding groove 45. The measuring column 41 is provided with a plurality of measuring columns 41 which are distributed in a rectangular shape. The lower end of the measuring column 41 is fixedly provided with a contact block 42, and the upper end of the measuring column 41 is fixedly provided with a limiting disc 43 which is a circular metal disc fixedly connected with the measuring column 41 by welding and used for limiting the rising height of the measuring column 41 to prevent it from being pulled out of the plane block 4. The two sides of the plane block 4 are symmetrically fixedly provided with scales 44. After the device is adjusted to the appropriate height, the contact block 42 at the lower end of the measuring column 41 is in contact with the surface of the building foundation. When the building foundation settles, the contact block 42 will descend with the settlement of the foundation, driving the measuring column 41 to move downward in the plane block 4. The sliding strip 46 on the outer surface of the measuring column 41 is clamped in the sliding groove 45 in the plane block 4, ensuring that the measuring column 41 can only move in the vertical direction. By observing the position change of the limiting disc 43 at the upper end of the measuring column 41 relative to the scales 44 on the two sides of the plane block 4, the settlement of the foundation can be measured. Since there are a plurality of measuring columns 41 distributed in a rectangular shape, the settlement of the foundation at different positions can be measured, so that the settlement of the foundation can be comprehensively understood.

[0020] The lower surface of the support 1 is fixedly provided with a support plate 11, and one side of the support plate 11 is symmetrically fixedly provided with a fixing block 12.

The clamping plates 14 and the reinforcing rods 13 are connected by bolt cooperation. First, the entire building foundation settlement detection device is placed on the building foundation to be detected by the support plate 11 below the support 1. The fixing block 12 on one side of the support plate 11 can assist the device to be better fixed on the ground, enhancing the stability of the device. The adjusting frame 2 is connected with the clamping plates 14 on the two sides of the support 1 by the reinforcing rods 13 on the two sides, and is further connected by bolts, further reinforcing the connection between the adjusting frame 2 and the support 1. The arrangement of the support plate 11 and the fixing block 12 enhances the stability of the device on the ground, preventing the device from shaking or moving during measurement. The use of the reinforcing pipe 24 and the reinforcing rod 13 further reinforces the structure of the device, so that the device can maintain good performance during long-term use, reducing measurement errors caused by unstable structure.

[0022] When the measurement position needs to be adjusted, the motor 22 on the upper surface of the adjusting frame 2 is started, the output end of the motor 22 drives the screw rod 21 to rotate, since the lifting frame 3 is sleeved on the outer surface of the screw rod 21 through the thread, and the sliding block 31 on one side of the lifting frame 3 is clamped in the adjusting frame 2, the limiting column 23 in the adjusting frame 2 penetrates through the lifting frame 3, which limits the rotation of the lifting frame 3, so that the rotation of the screw rod 21 is converted into the linear lifting movement of the lifting frame 3, at the same time, the reinforcing pipe 24 is sleeved on the outer surface of the screw rod 21 through the thread and is fixed on the upper surface of the lifting frame 3, which further enhances the stability of the lifting frame 3 during lifting;

[0023] After the device is adjusted to the appropriate height, the contact block 42 at the lower end of the measuring column 41 contacts the building foundation surface, when the building foundation settles, the contact block 42 will descend with the settlement of the foundation, driving the measuring column 41 to move downward in the plane block 4, the sliding strip 46 on the outer surface of the measuring column 41 is clamped in the sliding groove 45 in the plane block 4, which ensures that the measuring column 41 can only move in the vertical direction, by observing the position change of the limiting disc 43 at the upper end of the measuring column 41 relative to the two side scales 44 of the plane block 4, the settlement of the foundation can be measured, since a plurality of measuring columns 41 are arranged in a rectangular distribution, the settlement of the foundation at different positions can be measured, so that the settlement of the foundation can be comprehensively understood.
