Description

Technical Field

[0001] The invention belongs to the technical field of deep foundation pit monitoring, and in particular relates to a portable deep foundation pit monitoring device. Background Art

[0002] A deep foundation pit refers to an excavation depth of more than 5 meters or more than three basement floors, or a project with a depth of less than 5 meters but particularly complex geological conditions, surrounding environment and underground pipelines. The foundation pit project mainly includes the design and construction of the foundation pit support system and earth excavation, and is a highly comprehensive system project.

[0003] In the field of deep foundation pit engineering monitoring, real-time monitoring of the stability and safety of the foundation pit is crucial. Traditional deep foundation pit monitoring devices are often large in size and complex in structure, which are not easy to carry and install, and bring many inconveniences to on-site monitoring work. These devices usually require professional personnel to assemble and debug on-site, which is not only time-consuming and labor-intensive, but also increases the monitoring cost. During the construction of deep foundation pits, real-time monitoring of the foundation pit is required, and prism rods are used for monitoring in the prior art.

[0004] However, the existing prism rod is relatively long, so it is not convenient to carry the device, which greatly reduces the practicality of the deep foundation pit monitoring device, and it is not convenient to isolate and protect the monitor when carrying it.

[0005] In view of this, the inventor proposes a portable deep foundation pit monitoring device to solve the above problems. Summary of the invention

[0014] Through the sliding connection between the lead screw and the movable ring, the lead screw can be vertically limited, so that the lead screw can move up and down and rotate left and right on the movable ring. At the same time, the rotating lead screw is threadedly connected to the connecting block, so that the height of the connecting block on the lead screw can be adjusted, and then the support angle of the support rod can be adjusted through the connecting rod, so as to facilitate stable placement at uneven positions in the deep foundation pit.

[0015] Preferably, a rotating block is rotatably connected to the top end of the lead screw, a limiting cylinder is fixedly installed on the top of the positioning plate, a limiting block is slidably connected in the limiting cylinder, and the limiting block is fixedly connected to the bottom end of the corresponding lead screw.

[0016] The rotating block can drive the lead screw to rotate. At the same time, the limiting block is slidably connected to the limiting cylinder, so that the lead screw can be limited up and down, so that when the lead screw moves to a certain extent, it can be positioned, and then the angle of the support rod is adjusted and limited through the connecting block and the connecting rod.

[0017] Preferably, limiting holes are formed on both sides of the fixed cylinder, limiting rods are slidably connected to the inner walls of the limiting holes, both ends of the limiting rods are fixedly connected to the inner side of the top ring, and the limiting rods are fixedly connected to the bottom ends of the support columns.

The three support rods 41 are rotatably installed at the bottom of the positioning plate 3. A cushion ring 49 is slidably connected to the outer side of the fixed cylinder 1. The bottom end of the cushion ring 49 is fixedly installed with a movable ring 42. The movable ring 42 is drivingly connected to the three support rods 41. Through the rotational connection between the support rod 41 and the positioning plate 3, the bottom end of the support rod 41 can adjust the support area in the horizontal position at the bottom end of the fixed cylinder 1, and thus can adjust the support stability of the support rod 41 for the fixed cylinder 1.

[0045] Refer to Figure 4 As shown in the figure, three lead screws 431 are movably connected to the movable ring 42. A connecting block 45 is threadedly connected to the lead screw 431. The bottom of the connecting block 45 is rotatably connected to a connecting rod 46. The connecting rod 46 is rotatably connected to the corresponding support rod 41. Through the sliding connection between the lead screw 431 and the movable ring 42, the lead screw 431 can be vertically limited, so that the lead screw 431 can move up and down and rotate left and right on the movable ring 42. At the same time, the rotating lead screw 431 can adjust the height of the connecting block 45 on the lead screw 431 through the threaded connection with the connecting block 45, and thus can adjust the support angle of the support rod 41 through the connecting rod 46, so as to facilitate stable placement at uneven positions in the deep foundation pit.

[0046] Refer to Figure 2 As shown in the figure, the top end of the lead screw 431 is rotatably connected to a rotating block 44. The top of the positioning plate 3 is fixedly installed with a limiting cylinder 432. A limiting block 433 is slidably connected in the limiting cylinder 432. The limiting block 433 is fixedly connected to the bottom end of the corresponding lead screw 431. The lead screw 431 can be rotated by the rotating block 44. At the same time, the limiting block 433 can limit the lead screw 431 up and down through the sliding connection with the limiting cylinder 432, so that when the lead screw 431 moves to a certain extent, it can be positioned, and then the angle of the support rod 41 can be adjusted and limited through the connecting block 45 and the connecting rod 46.

[0047] Refer to Figure 2 As shown in the figure, limiting holes 11 are opened on both sides of the fixed cylinder 1. A limiting rod 10 is slidably connected to the inner wall of the limiting hole 11. Both ends of the limiting rod 10 are fixedly connected to the inner side of the top ring 9. The limiting rod 10 is fixedly connected to the bottom end of the support column 2. Through the sliding connection between the limiting rod 10 and the limiting hole 11, the support column 2 can be limited, and at the same time, the top ring 9 can also be limited.

[0048] Refer to Figure 2 As shown in the figure, a top spring 48 is fixedly installed on the top of the positioning plate 3. The top end of the top spring 48 is fixedly connected to the bottom of the movable ring 42. Through the arrangement of the top spring 48, it is convenient to push the movable ring 42 back to its original position, and at the same time, the connecting block 45 and the support rod 41 can be pressed, so that the three support rods 41 retract.

[0049] As can be seen from the above, during operation, rotate the rotating ring 8. The rotating rotating ring 8 drives the top ring 9 to move through the threaded connection with the fixed cylinder 1. Through the fixed connection of the limiting rod 10 with the top ring 9 and the support column 2, the height of the support column 2 and the monitor 6 can be changed. When the monitor 6 moves downward to the lowest position, it can be isolated and protected by the protective cover 7, which is convenient for safe carrying. Through the sliding connection of the lead screw 431 with the movable ring 42, the vertical limit of the lead screw 431 can be achieved, so that the lead screw 431 can move up and down and rotate left and right on the movable ring 42. At the same time, the rotating lead screw 431 drives the connecting block 45 to move up and down through the threaded connection with the connecting block 45, and then the support angle of the support rod 41 can be adjusted through the connecting rod 46, which is convenient for stable placement at uneven positions in the deep foundation pit. The rotating block 44 can drive the lead screw 431 to rotate. At the same time, the limiting block 433 slides with the limiting cylinder 432, so that the up and down limit of the lead screw 431 can be achieved. When the lead screw 431 moves to a certain extent, it can be positioned, and then the angle of the support rod 41 is adjusted and limited through the connecting block 45 and the connecting rod 46.
