Description
Technical Field
[0001] The present application relates to the technical field of foundation settlement detection, and in particular to a foundation settlement detection device. Background Art
[0002] The compaction of the foundation soil layer under the action of the upper buildings or other additional stresses will cause the foundation surface to sink vertically and move horizontally. The vertical deformation of the foundation is called foundation settlement. Excessive settlement, especially uneven settlement, will cause the building to tilt, crack, etc., which will cause great safety hazards. In order to improve the safety of the building, the foundation needs to be tested multiple times during the construction process and for a period of time after the construction.
[0003] The utility model patent with announcement number CN219933622U proposes a foundation settlement detection device, including an instrument body and a bracket connected to the instrument body, the bracket includes a fixed seat, a telescopic column and three support leg assemblies, the telescopic column is vertically arranged in the middle position of the bottom surface of the fixed seat, and the end of the telescopic column away from the fixed seat is connected to three tops, and the support leg assembly includes a connector and a telescopic support rod hinged to the connector, and the connector is adjustably connected to different positions of the fixed seat in the circumferential direction, and the specific adjustment method can be sliding adjustment or plug-in. When in use, the bracket is first supported on the ground by the telescopic column, the level bead on the instrument body is observed to confirm that the device has reached a horizontal state, and then the three support leg assemblies are adjusted to abut against the ground, so that the bracket can be stably supported on the ground, and there is no need to move the entire device, which is convenient for the operator to operate and improves the leveling efficiency.
[0004] The above detection device supports the level to a suitable height through a bracket for easy detection. When the bracket is knocked over by external force, the level will directly collide with the ground due to lack of protection, which can easily cause damage to the level. Utility Model Content
[0005] The utility model aims to solve or at least alleviate the problem that the existing detection device lacks a protective structure and when the device falls over, the level is easily damaged due to direct collision with the ground.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A foundation settlement detection device comprises a level with a slide plate installed at the bottom and a support structure for supporting the level to an appropriate height, a protective cover with a top opening and a sliding connection to the slide plate is provided around the side of the level, a sliding rod is fixedly connected to the center of the lower surface of the sliding rod, the bottom end of the sliding rod passes through the bottom wall of the protective cover and is slidingly connected to the bottom wall of the protective cover, a limiting block is fixedly connected to the bottom end of the sliding rod, an elastic reset device is provided on the sliding rod between the limiting block and the bottom wall of the protective cover, and the supporting structure comprises three supporting legs rotatably connected around the bottom end of the protective cover, a supporting plate is provided between the three supporting legs, and the peripheral side of the supporting plate is rotatably connected to the three supporting legs respectively through linkage rods.
[0008] By adopting the above technical scheme, when taking measurements, first open the three supporting legs installed at the bottom of the protective cover. At this time, the supporting legs drive the linkage rod to rotate, push the support plate up, thereby squeezing the bottom end of the slide bar, and push the slide bar up synchronously, so that the level in the inner cavity of the protective cover can be pushed out for measurement. At this time, the spring is pushed by the limit block and is in a contracted state. When the entire device topples over due to external force, the bottom of the supporting legs is separated from the ground, losing the support and limiting effect of the ground, and can be rotated arbitrarily to make the support plate lose its supporting effect on the bottom of the slide bar. At this time, the spring can push the limit block to reset under its own action, and at the same time pull the level into the inner cavity of the protective cover for protection, thereby avoiding as much as possible the problem that the existing detection device lacks a protective structure and the level is easily damaged due to direct collision with the ground when the device topples over.
[0009] Optionally, the protective cover has a cylindrical structure, the inner cavity volume of the protective cover is larger than the total volume of the level and the slide, and the inner diameter of the protective cover is equal to the diameter of the slide.
[0010] By adopting the above technical solution, the inner cavity volume of the protective cover is larger than the total volume of the level and the skateboard, so that when the entire device is tilted, the level can be completely embedded in the protective cover and protected by the protective cover. The inner diameter of the protective cover is equal to the diameter of the skateboard, which is used to guide the sliding path of the skateboard. At the same time, it can be supported by the side wall of the skateboard to minimize the shaking of the level in the inner cavity of the protective cover.
[0011] Optionally, the elastic reset device is a spring sleeved on the outer surface of the slide rod, with both ends of the spring respectively abutting against the bottom wall of the protective cover and the upper surface of the limit block, and the maximum compression length of the spring is not less than the height of the level.
[0012] By adopting the above technical solution, when the level slides out of the protective cover, the spring is in a compressed state. When the entire device tilts over, the spring can push the slide rod downward under the action of the restoring force, thereby pulling the level into the inner cavity of the protective cover for protection.
[0013] Optionally, the supporting legs include three first legs rotatably connected to the outer wall of the bottom end of the protective cover, and the bottom ends of the three first legs are slidably connected to the second legs.
[0014] By adopting the above technical solution, a first leg and a second leg are provided, and the first leg and the second leg are slidably connected, so that the user can adjust the length of the supporting leg according to his own needs.
[0015] Optionally, a foot is fixedly connected to one end of the second leg located outside the first leg, and the bottom end of the foot is a conical structure.
[0016] By adopting the above technical solution, a support foot with a conical structure is installed at the bottom end of the second support leg, which makes it convenient for the user to press the support foot into the ground to improve the stability of the support.
[0017] Optionally, a limit bolt threadedly connected to the first leg is provided on the outer wall of the connection between the first leg and the second leg, and one end of the limit bolt located in the inner cavity of the first leg abuts against the second leg.
[0018] By adopting the above technical solution, when the user slides the second leg out to a suitable length, the limiting bolt can be screwed into the first leg to squeeze the second leg through the limiting bolt so that the second leg is relatively fixed to the first leg.
[0019] Optionally, corresponding connecting seats are welded to the side wall of the support plate close to the first leg and the bottom ends of the three first legs, and both ends of the linkage rod are rotatably connected to the first leg and the support plate through the connecting seats.
[0020] By adopting the above technical solution, a connecting seat is provided to rotatably connect the two ends of the linkage rod to the first leg and the support plate respectively through the connecting seat, so that the support leg can adjust the height of the support plate by adjusting the opening angle.
[0021] In summary, the beneficial effects of this application are as follows:
[0022] The present application realizes the coordination among structures such as protective cover, sliding rod, spring and support plate. When the whole device topples over due to external force, the bottom of the supporting leg separates from the ground and loses the support and limiting effect of the ground. The support plate can be rotated arbitrarily to make it lose its supporting effect on the bottom of the sliding rod. At this time, the spring can push the limit block to reset under its own action, and at the same time pull the level into the inner cavity of the protective cover for protection, thus avoiding as much as possible the problem that the existing detection device lacks a protective structure and the level is easily damaged by direct collision with the ground when the device topples over.

[0027] The following is combined with Figure 1-3 This application is described in further detail.
[0028] See also Figure 1-3 A foundation settlement detection device includes a level 1 with a slide plate 2 installed at the bottom and a support structure for supporting the level 1 to a suitable height. When in use, the level 1 is supported to a suitable height by the support structure, and the level 1 is used to measure the height of the same position, and the heights measured at different times are compared to calculate whether the foundation has settled.
[0029] A protective cover 3 is provided around the side of the level 1 and is slidably connected to the slide plate 2 and has an open top. When the level 1 is tipped over, it can slide down and fall into the inner cavity of the protective cover 3, and the level 1 is protected by the protective cover 3.
[0030] A slide rod 4 is fixedly connected to the center of the lower surface of the slide plate 2. The bottom end of the slide rod 4 passes through the bottom wall of the protective cover 3 and is slidably connected to the bottom wall of the protective cover 3. When the slide rod 4 slides upward, it can push the slide plate 2 to move upward in the inner cavity of the protective cover 3, thereby pushing the level 1 out of the inner cavity of the protective cover 3, making it convenient for users to perform measurement work.
[0031] A limiting block 5 is fixedly connected to the bottom end of the slide rod 4, and an elastic reset device is sleeved on the slide rod 4 between the limiting block 5 and the bottom wall of the protective cover 3. The supporting structure is three supporting legs rotatably connected to the periphery of the bottom end of the protective cover 3, and a support plate 11 is provided between the three supporting legs. The periphery of the support plate 11 is rotatably connected to the three supporting legs respectively through a linkage rod 13.
[0032] Reference Figure 1 The protective cover 3 is a cylindrical structure, the inner volume of the protective cover 3 is larger than the total volume of the level 1 and the slide 2, and the inner diameter of the protective cover 3 is equal to the diameter of the slide 2. The inner volume of the protective cover 3 is larger than the total volume of the level 1 and the slide 2, so that when the whole device is tipped over, the level 1 can be completely embedded in the protective cover 3, and the level 1 is protected by the protective cover 3. The inner diameter of the protective cover 3 is equal to the diameter of the slide 2, which is used to guide the sliding path of the slide 2, and can be supported by the side wall of the slide 2, so as to avoid the level 1 from shaking in the inner cavity of the protective cover 3 as much as possible.
[0033] Reference Figure 2The elastic reset device is a spring 6 sleeved on the outer surface of the slide bar 4. The two ends of the spring 6 are respectively in contact with the bottom wall of the protective cover 3 and the upper surface of the limit block 5. The maximum compression length of the spring 6 is not less than the height of the level 1. When the level 1 slides out of the protective cover 3, the spring 6 is in a compressed state. When the whole device is tilted, the spring 6 can push the slide bar 4 downward under the action of the restoring force, thereby pulling the level 1 into the inner cavity of the protective cover 3 for protection.
[0034] Reference Figure 2 The support legs include three first legs 7 rotatably connected to the outer wall of the bottom end of the protective cover 3, and the bottom ends of the three first legs 7 are all slidably connected to the second legs 8. The first legs 7 and the second legs 8 are provided, and the first legs 7 and the second legs 8 are slidably connected to each other, so that the user can adjust the length of the support legs according to their own needs.
[0035] Reference Figure 3 The second leg 8 is fixedly connected to a foot 10 at one end outside the first leg 7, and the bottom of the foot 10 is a conical structure. The foot 10 with a conical structure is installed at the bottom of the second leg 8, which is convenient for the user to press the foot 10 into the ground to improve the stability of the support.
[0036] Reference Figure 3 A stop bolt 9 is provided on the outer wall of the connection between the first leg 7 and the second leg 8, and is screwed to the first leg 7. One end of the stop bolt 9 located in the inner cavity of the first leg 7 abuts against the second leg 8. When the user slides the second leg 8 out to a suitable length, the stop bolt 9 can be screwed into the first leg 7, and the second leg 8 can be squeezed by the stop bolt 9 to fix the second leg 8 relative to the first leg 7.
[0037] Reference Figure 3 The supporting plate 11 is welded with corresponding connecting seats 12 near the side wall of the first supporting leg 7 and the bottom ends of the three first supporting legs 7, and the two ends of the linkage rod 13 are rotatably connected with the first supporting leg 7 and the supporting plate 11 through the connecting seats 12. The connecting seats 12 are provided to rotatably connect the two ends of the linkage rod 13 with the first supporting leg 7 and the supporting plate 11 through the connecting seats 12, so that the support legs can adjust the height of the supporting plate 11 by adjusting the opening angle.
[0038] The implementation principle of the present application is: when taking measurements, first open the three supporting legs installed at the bottom of the protective cover 3. At this time, the supporting legs drive the linkage rod 13 to rotate, pushing the support plate 11 upward, thereby squeezing the bottom end of the slide bar 4, and pushing the slide bar 4 to move upward synchronously, so that the level 1 in the inner cavity of the protective cover 3 can be pushed out for measurement. At this time, the spring 6 is pushed by the limit block 5 and is in a contracted state. When the entire device tilts due to external force, the bottom of the supporting legs is separated from the ground, losing the support and limiting effect of the ground, and can be rotated arbitrarily to make the support plate 11 lose its supporting effect on the bottom of the slide bar 4. At this time, the spring 6 can push the limit block 5 to reset under its own action, and at the same time pull the level 1 into the inner cavity of the protective cover 3 for protection, thereby avoiding the lack of protective structure in the existing detection device as much as possible. When the device tilts, the level 1 is easily damaged due to direct collision with the ground.
