Description

Technical Field

[0001] This application belongs to the technical field of urban rail transit engineering monitoring, and more specifically, it relates to a recovery device for monitoring construction points of ground surface and pipeline settlement in subway engineering. Background Technology

[0002] During subway construction, numerous settlement monitoring points need to be set up at the surface and along pipelines to ensure construction safety and environmental stability. These monitoring points are typically established by embedding steel reinforcement markers near the foundation or pipelines. If the steel reinforcement remains underground for an extended period after the monitoring points have completed their monitoring tasks, it may hinder subsequent construction and pose safety hazards; therefore, timely recovery of the steel reinforcement is necessary.

[0003] Currently, most steel reinforcement recycling at monitoring points relies on primitive methods such as manual hammering and prying, which are inefficient. A small number of projects use vehicle-mounted mechanical extraction, but this method is difficult to operate due to complex terrain and environment, resulting in low recycling efficiency. Utility Model Content

[0004] The purpose of this application is to provide a recycling device for monitoring and recycling points of ground surface and pipeline settlement in subway engineering, so as to solve the technical problem that the efficiency of manual recycling and mechanical vehicle-mounted recycling in the prior art is not high.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a recovery device for monitoring and recovering settlement points of subway engineering surface and pipeline construction, comprising:

[0006] A support frame, used for placement on the ground;

[0007] A lifting drive component has a fixing part and a lifting part connected above the fixing part, wherein the fixing part is connected to the bracket;

[0008] The tension frame is connected at its top to the lifting unit and at its bottom to the support frame.

[0009] A support plate, connected to the bottom end of the tension frame, is used to connect the reinforcing bars at the monitoring points; and

[0010] A fixing component, disposed on the support plate, is used to clamp and fix the monitoring point reinforcing bar to the support plate.

[0011] In one possible implementation, based on the above technical solutions, the fixing component includes:

[0012] The adjustment frame is arranged in a ring and extends horizontally through the support plate; the adjustment frame is located on one side of the support plate as a clamping part and on the other side of the support plate as an adjustment part.

[0013] The driving unit drives the adjusting unit to move away from the clamping unit, so that the clamping unit clamps the monitoring point steel bar on the support plate.

[0014] In one possible implementation, based on the above technical solutions, the driving unit includes:

[0015] A connecting plate is fixed to the side of the support plate near the adjusting part;

[0016] The fixing bolts are vertically threaded onto the connecting plate; and

[0017] The extrusion block is rotatably connected to the bottom end of the fixing bolt and located below the connecting plate; the bottom of the extrusion block away from the clamping part is an inclined surface, which is used to extrude the adjusting part to move it.

[0018] In one possible implementation, based on the above technical solutions, the positions of the support plate and the clamping part facing each other are both arc surfaces adapted to the reinforcing bars at the monitoring points.

[0019] In one possible implementation, based on the above technical solutions, the tension frame includes:

[0020] Two connecting rods are located on both sides of the bracket, with the top of the connecting rods connected to the lifting part and the bottom of the connecting rods connected to the support plate.

[0021] In one possible implementation, based on the above technical solutions, the tension frame further includes:

[0022] A reinforcing rod is fixed between the two connecting rods.

[0023] In one possible implementation, based on the above technical solutions, the top end of the connecting rod is detachably connected to the lifting part.

[0024] In one possible implementation, based on the above technical solutions, the bottom end of the connecting rod is detachably connected to the support plate.

[0025] In one possible implementation, based on the above technical solutions, the tension frame further includes:

[0026] The mounting frame is fixed to the bottom ends of the two connecting rods and allows one end of the support plate to be inserted.

[0027] A connecting component is provided between the mounting frame and the support plate, and the connecting component is used to detachably fix the mounting frame and the support plate.

[0028] In one possible implementation, based on the above technical solutions, the connection component includes:

[0029] Connecting bolts, vertically penetrating the mounting frame and the support plate; and

[0030] A connecting nut is threaded onto the connecting bolt.

[0031] The beneficial effects of the surface and pipeline settlement monitoring point recovery device provided in this application are as follows: Compared with the prior art, when recovering the steel bars at the monitoring points, the present application places the support on the ground surface and makes one side of the support plate abut against the side of the steel bars at the monitoring points. The steel bars at the monitoring points are clamped and fixed to the support plate by the fixing components. At this time, the lifting drive component drives the lifting part to rise. The lifting part drives the steel bars at the monitoring points to move upward through the tension frame and the support plate, which can release the static friction between the steel bars at the monitoring points and the soil, and easily pull out the steel bars at the monitoring points. This not only improves the recovery efficiency of the steel bars at the monitoring points, but is also suitable for various site environments. Attached Figure Description

[0049] The present application provides a description of a recovery device for monitoring and monitoring settlement of subway engineering surface and pipelines.

[0050] like Figure 1 and Figure 2 As shown, one embodiment of this application provides a recovery device for monitoring construction points of ground and pipeline settlement in subway engineering, including a bracket 1, a lifting drive component 2, a tension frame 3, a support plate 4, and a fixing component 5.

[0051] The bracket 1 is used to place on the ground; the lifting drive 2 has a fixing part 21 and a lifting part 22 connected above the fixing part 21, and the fixing part 21 is connected to the bracket 1; the top end of the tension frame 3 is connected to the lifting part 22, and the bottom end is located below the bracket 1; the support plate 4 is connected to the bottom end of the tension frame 3 and is used to connect the monitoring point steel bars; the fixing component 5 is set on the support plate 4 and is used to clamp and fix the monitoring point steel bars to the support plate 4.

[0052] Specifically, in this embodiment, the lifting drive component 2 is a detachable jack.

[0053] This embodiment provides a surface and pipeline settlement monitoring point recovery device for subway engineering. Compared with the prior art, when recovering the monitoring point steel bars, the bracket 1 is placed on the ground surface, and one side of the support plate 4 abuts against the side of the monitoring point steel bar. The monitoring point steel bar is clamped and fixed to the support plate 4 by the fixing component 5. At this time, the lifting drive component 2 drives the lifting part 22 to rise. The lifting part 22 drives the monitoring point steel bar to move upward through the tension frame 3 and the support plate 4, which can release the static friction between the monitoring point steel bar and the soil, and easily pull out the monitoring point steel bar. This not only improves the recovery efficiency of the monitoring point steel bar, but is also suitable for various site environments.

[0054] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0055] The fixing component 5 includes an adjusting frame 6 and a driving part. The adjusting frame 6 is arranged in a ring and extends laterally through the support plate 4; the adjusting frame 6 is located on one side of the support plate 4 as a clamping part 61 and on the other side of the support plate 4 as an adjusting part 62.

[0056] The drive unit moves away from the clamping unit 61 via the drive adjustment unit 62, so that the clamping unit 61 clamps the monitoring point steel bar onto the support plate 4.

[0057] While placing the bracket 1 on the ground, the monitoring point steel bar passes between the support plate 4 and the clamping part 61. The adjustment part 62 is moved away from the clamping part 61 by the drive part, so that the clamping part 61 and the support plate 4 can clamp and fix the monitoring point steel bar. The adjustment frame 6 can be adjusted according to the monitoring point steel bars of different specifications and sizes to adapt to various types of recycling work.

[0058] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0059] The drive unit includes a connecting plate 51, a fixing bolt 52, and a pressing block 53. The connecting plate 51 is fixed to the side of the support plate 4 near the adjusting part 62. The fixing bolt 52 is vertically threaded onto the connecting plate 51. The pressing block 53 is rotatably connected to the bottom end of the fixing bolt 52 and is located below the connecting plate 51. The pressing block 53 and the support plate 4 are vertically slidably connected. The bottom of the pressing block 53 is inclined on the side away from the clamping part 61. The inclined surface is used to press the adjusting part 62 to make it move.

[0060] By rotating the fixing bolt 52, the up and down movement of the extrusion block 53 can be precisely controlled. When the fixing bolt 52 drives the extrusion block 53 to move downward, the inclined surface will squeeze the adjustment part 62, converting the vertical force into the horizontal force, thereby realizing the movement of the adjustment part 62 and completing the clamping of the steel bar at the monitoring point.

[0061] Furthermore, the threaded connection has a self-locking function, which can maintain stability after the position of the extrusion block 53 is adjusted, preventing the extrusion block 53 from moving due to external force during the recycling process, and improving the fixing effect between the extrusion block 53 and the adjustment frame 6.

[0062] like Figure 1 and Figure 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0063] The support plate 4 and the clamping part 61 are positioned opposite each other at arc surfaces that are adapted to the reinforcing bars at the monitoring points.

[0064] During clamping, the arc surface can evenly distribute pressure, avoiding damage to the reinforcing bar caused by excessive local pressure. Compared with flat clamping, the arc surface can provide a larger contact area, increasing friction and making the reinforcing bar more secure and less prone to loosening during clamping.

[0065] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0066] The tension frame 3 includes two connecting rods 31, which are located on both sides of the support 1. The top end of the connecting rod 31 is connected to the lifting part 22, and the bottom end is connected to the support plate 4.

[0067] The two connecting rods 31 enable the tension frame 3 to evenly bear the force transmitted by the lifting drive component 2, distributing the force evenly across the entire tension frame 3, reducing the stress on individual components, and improving the overall stability of the device.

[0068] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0069] The tension frame 3 also includes a reinforcing rod 32, which is fixed between the two connecting rods 31.

[0070] During the recycling process, the tension frame 3 needs to withstand large tensile and compressive forces. The reinforcing rod 32 can effectively connect the two connecting rods 31 to form a more robust whole, which improves the load-bearing capacity of the tension frame 3 and reduces the deformation of the connecting rods 31 under stress.

[0071] like Figures 1 to 2 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0072] The top end of the connecting rod 31 is detachably connected to the lifting part 22 by bolts. The bolts pass through the lifting part 22 from top to bottom and are then threaded onto the connecting rod 31.

[0073] In actual use, different construction environments and recycling needs may be encountered. The detachable connection allows the connecting rod 31 to be replaced or adjusted according to the actual situation. Moreover, when the lifting unit 22 or the tension frame 3 needs to be repaired or replaced, the connecting rod 31 can be easily removed from the lifting unit 22.

[0074] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0075] The bottom end of the connecting rod 31 is detachably connected to the support plate 4.

[0076] When the connecting rod 31 or the support plate 4 is damaged or needs to be cleaned, the connecting rod 31 can be easily removed from the support plate 4 for individual repair or replacement; different support plates 4 can also be replaced according to different usage requirements.

[0077] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0078] The tension frame 3 also includes a mounting frame 33, which is fixed to the bottom of the two connecting rods 31 and allows one end of the support plate 4 to be inserted.

[0079] A connecting component 7 is provided between the mounting frame 33 and the support plate 4. The connecting component 7 is used to detachably fix the mounting frame 33 and the support plate 4.

[0080] The mounting frame 33 provides a positioning and support function for the support plate 4, ensuring the positional accuracy of the support plate 4 during installation; the connecting component 7 makes the connection between the mounting frame 33 and the support plate 4 more secure.

[0081] like Figures 2 to 3 As shown, this application provides another specific implementation method based on the above-described implementation method as follows:

[0082] The connecting assembly 7 includes a connecting bolt 71 and a connecting nut 72; the connecting bolt 71 vertically penetrates the mounting frame 33 and the support plate 4; the connecting nut 72 is threadedly connected to the connecting bolt 71.

[0083] The mounting frame 33 and the support plate 4 are fixed by the cooperation of the connecting bolt 71 and the connecting nut 72. The structure is simple and the fixing effect is good. It can generate a tight connection force between the mounting frame 33 and the support plate 4, ensuring the stability of their relative positions.

[0084] Furthermore, it is easy to adjust and disassemble. When it is necessary to adjust or replace the mounting frame 33 and the support plate 4, simply unscrew the connecting nut 72. The operation is convenient and quick.

[0085] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
