Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically to a displacement monitoring and early warning device for engineering supervision. Background Technology

[0002] After the main structure of the building is poured, in order to prevent the poured wall panels from tilting, it is necessary to monitor the displacement of the building in real time to ensure the safety and quality of the project.

[0003] Currently, the commonly used displacement monitoring methods mainly involve manual measurement using instruments such as levels, theodolites, and total stations. When using these instruments manually, adjustments and observations are required, which not only results in a large workload and low efficiency, but also makes it difficult to meet the needs of continuous monitoring, leading to high labor costs. Utility Model Content

[0004] The purpose of this utility model is to provide a displacement monitoring and early warning device for engineering supervision in order to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The present invention provides a displacement monitoring and early warning device for engineering supervision, comprising a support rod 1, a lifting assembly fixedly connected to the support rod 1, and a support rod 2 rotatably connected to the lifting end of the lifting assembly, and the support rod 2 being able to rotate to the position where the length of the support rod 1 extends. A locking assembly is provided between the lifting assembly and the support rod 2 for fixing the support rod 2 to the position where the length of the support rod 1 extends.

[0007] A pressure sensor is fixedly connected to the upper end of the second support rod.

[0008] A movable component is fixedly connected to the support rod, and the moving direction of the movable component is perpendicular to the length direction of the support rod. A pressure sensor is fixedly connected to the moving end of the movable component.

[0009] Using the above-mentioned displacement monitoring and early warning device for engineering supervision, the second support rod is rotated to the position of the extension line of the first support rod and fixed by the locking component. The first support rod and the second support rod can be combined to form a long rod. The first support rod and the second support rod are erected on the ground. The second support rod is moved upward by the lifting component so that the pressure sensor pair supports the roof until the first support rod and the second support rod can be stationary between the ground and the roof.

[0010] Then, the pressure sensor 2 is moved by the moving component so that it supports the wall. At this time, the values ​​of pressure sensor 1 and pressure sensor 2 are recorded. During subsequent monitoring, if the values ​​of pressure sensor 1 and pressure sensor 2 change, it indicates that the wall and roof slab have shifted.

[0011] Preferably, a base is fixedly connected to the lower end of the support rod.

[0012] Preferably, a handle is fixedly connected to one of the support rods.

[0013] Preferably, the lifting assembly includes a movable sleeve and a lead screw. The lead screw is vertically rotatably connected to a support rod via a bearing seat. The movable sleeve is slidably connected to the surface of the support rod. A connecting block is threaded onto the lead screw, and the connecting block is fixedly connected to the movable sleeve.

[0014] Preferably, a rotating shaft is rotatably connected to the support rod, and bevel gears are fixedly connected to both the rotating shaft and the lead screw. The two bevel gears mesh, and a crank handle is fixedly connected to the rotating shaft.

[0015] Preferably, the locking assembly includes a spring pin and a fixed sleeve, which are fixedly connected to the movable sleeve and the second support rod, respectively, and the spring pin is inserted into the fixed sleeve.

[0016] Preferably, the movable component includes a mounting plate fixedly connected to a support rod, a rectangular slide rod slidably connected to the mounting plate, and a pressure sensor is fixedly connected to the end of the rectangular slide rod away from the support rod. A threaded sleeve is rotatably connected to the mounting plate, and a screw is threadedly connected to the threaded sleeve, with the end of the screw fixedly connected to the rectangular slide rod.

[0017] Preferably, both support rod one and support rod two are square rods.

[0018] The beneficial effects are:

[0019] By combining support rod one and support rod two, a long rod can be formed. By moving support rod two upward through the lifting component, pressure sensor one is supported on the roof. By moving pressure sensor two through the moving component, pressure sensor two is supported on the wall. By comparing and recording the changes in the values ​​of pressure sensor one and pressure sensor two before and after, it is possible to know whether the wall and roof have shifted. This method is not only highly efficient in monitoring, but also saves manpower. Attached Figure Description

The movable sleeve 12 is slidably connected to the surface of the support rod 1. A connecting block 15 is threaded onto the lead screw 13. The connecting block 15 is fixedly connected to the movable sleeve 12. When the lead screw 13 is rotated, the lead screw 13 can drive the movable sleeve 12 to move along the support rod 1 through the connecting block 15.

[0035] A rotating shaft 14 is rotatably connected to the support rod 1. Both the rotating shaft 14 and the lead screw 13 are fixedly connected to bevel gears 16. The two bevel gears 16 mesh. A crank handle 17 is fixedly connected to the rotating shaft 14.
