Description

Technical Field

[0001] The invention relates to the field of settlement monitoring, and in particular to a subway line settlement monitoring device. Background Art

[0002] Subway is a form of rail transportation, referring to an urban rail transit system that mainly operates underground, which is the abbreviation of "underground railway" or "subway". Many such systems may be converted into ground or elevated sections outside the city center in order to adapt to the construction environment and consider the construction and operation costs. The subway is an urban rail transit system that covers various underground and above-ground exclusive rights of way in urban areas, with high density and high capacity. During the construction of subway tunnels or after completion, it is still necessary to monitor the corresponding settlement conditions at all times to ensure safety in use.

[0003] At present, static levels are usually used to monitor settlement in this area. Corresponding static levels are arranged at each required detection point. Each static level is connected by a pipeline with detection fluid flowing through the pipeline. The static level is used to promptly and accurately detect the settlement of each detection point. The installation and fixation stability of the static level is crucial to the final detection result. At present, the static level is mainly installed and fixed vertically through the mounting holes on the base, which has limitations on the usage scenario, that is, the detection point needs to have corresponding hard mounting components for the base to be installed and fixed. In the detection of subway lines, there may not be a hard mounting part at the detection point. For example, the ground may be a soil surface, which makes installation inconvenient. Summary of the invention

[0004] In order to further improve the convenience and versatility of installation, the present application provides a subway line settlement monitoring device.

[0005] The present application provides a subway line settlement monitoring device, which adopts the following technical solution: A subway line settlement monitoring device includes a static level and a base, wherein a slide groove is horizontally arranged on the base, and both ends of the slide groove pass through the side walls of the base, and a mounting plate is slidably connected in the slide groove. The mounting plate includes two plate bodies hinged to each other on one side, and the plate bodies are provided with fixing holes. A plug-in column is vertically slidably connected to the base, and the bottom end of the plug-in column is conically arranged. The plate body is provided with a through groove for the plug-in column to pass through, and the through groove is adapted to the plug-in column.

[0006] Optionally, two mounting plates and two plug-in columns are symmetrically arranged, and both plates have through grooves. When the plug-in column is plugged into a plate away from the center of the base, the plate is entirely received in the slide groove; when the plug-in column is plugged into a plate close to the center of the base, the hinge of the plate is located outside the slide groove.

[0007] Optionally, a convex edge is protruding from the bottom side wall of the base, the convex edges are symmetrically arranged, and a through hole is vertically opened on the convex edge.

[0008] Optionally, an elastic member is provided in the middle of the slide groove, and the elastic member abuts against one side of the mounting plate and is used to drive the other end portion thereof to move out of the slide groove.

[0009] Optionally, a top block is provided on the bottom wall of the base, the top block is vertically slidably connected to the base, the top end of the top block is a driving end, the elastic member is a rubber block, and the driving end is used to abut against and extrude the elastic member.

[0010] Optionally, the top of the plug-in column has a head, the width of the head is larger than the plug-in column, and a horizontal turning bar is provided on the side wall of the static level, one end of the turning bar is rotatably connected to the static level, and the other end of the turning bar is used to support the head of the plug-in column.

[0011] Optionally, the plug-in column includes an outer sleeve and an inner column, the inner column is threadedly connected to the outer sleeve, the bottom end of the inner column passes through the outer sleeve and is conical, and the top end of the inner column has an operating hole.

[0014] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the ground of the installation site is muddy, the plug-in column can be inserted into the mud for installation and fixation. When there is no hard installation component on the ground for the base to be installed, the installation plate can be pulled out and then the plate body can be turned vertically. The partially pulled-out installation plate can be fixed with the help of the plug-in column, realizing the multi-purpose of the plug-in column. The base can be installed and fixed on the side with the help of the fixing holes on the plate body, expanding the installation method of the base, and effectively improving the convenience and versatility of the installation of the static level; 2. The design of the elastic part and the top block drives the top block to move upward to squeeze the elastic part when the base is placed on the ground. After the elastic part is compressed, it can drive one end of the mounting plate to move out of the slide groove, providing a fulcrum for easy hand-held extraction of the mounting plate.

[0015] 3. The inner column of the plug-in column is threadedly connected to the outer shell.

[0020] The following is combined with Figure 1-4 This application is described in further detail.

[0021] Example 1 A subway line settlement monitoring device, such as Figure 1-Figure 3 As shown, it includes a static level 1 and a base 2, the base 2 is fixed at the bottom of the static level 1, a slide groove 3 is horizontally opened on the base 2, both ends of the slide groove 3 pass through the two opposite side walls of the base 2, a mounting plate 4 is horizontally slidably connected in the slide groove 3, and at the same time, a plug-in column 5 is vertically slidably connected on the opposite sides of the base 2, the bottom end of the plug-in column 5 is conically arranged and used to be inserted into the mud ground, the base 2 has a vertical groove 6 for the plug-in column 5 to slide vertically, and at the same time, a through groove 7 for the plug-in column 5 to pass through is opened on the mounting plate 4, and the through groove 7 is adapted to the plug-in column 5, and in addition, there are outwardly protruding convex edges 8 at the opposite ends of the base 2, and a through hole 9 is vertically opened on the convex edge 8, and the through hole 9 vertically penetrates and is used to install fasteners.

[0022] In this way, when the ground at the installation site has hard mounting components, the fasteners can be inserted into the through holes 9 on the flange 8 for direct connection and fixation. When the ground at the installation site is muddy, the plug-in column 5 can be inserted into the mud for installation and fixation. This allows the base 2 to adapt to installation environments in more different occasions, effectively improving the convenience and versatility of installation of the static level 1.

[0023] like Figure 1As shown, there is a head 10 at the top of the plug-in column 5, and the width of the head 10 is greater than the width of the vertical groove 6 and the plug-in column 5. A turn bar 11 is provided on the side wall of the static level 1 to support the head 10 of the plug-in column 5. One end of the turn bar 11 in the length direction is rotatably connected to a fixed block 12 on the side wall of the static level 1. After the plug-in column 5 is lifted up and the turn bar 11 is rotated, the head 10 of the plug-in column 5 can be supported by the turn bar 11. At this time, the bottom end of the plug-in column 5 is retracted into the base 2 to achieve the storage of the bottom end of the plug-in column 5, so that the bottom end of the plug-in column 5 does not protrude from the bottom of the base 2 to affect the installation. In order to further improve the support stability of the head 10, corresponding and attractive first magnetic blocks 13 are embedded on the turn bar 11 and the head 10, and the stability is further improved by means of magnetic adsorption to prevent the plug-in column 5 from accidentally falling off.

[0024] like Figure 2 As shown, the plug-in column 5 includes an outer sleeve 14 and an inner column 15. The outer sleeve 14 is fixed to the head 10, and the inner column 15 is threadedly connected in the outer sleeve 14. The bottom end of the inner column 15 passes through the outer sleeve 14 and is set in a cone shape. The top of the inner column 15 is provided with an operating hole 16 for rotation operation. The operating hole 16 is a hexagonal hole. After the plug-in column 5 is inserted into the soil, the inner column 15 can be further rotated downward by a hexagonal wrench to increase the total depth of the plug-in column 5 inserted into the soil, thereby further improving the installation stability. In addition, the conical bottom end of the inner column 15 is an insertion end 17, and the outer wall of the insertion end 17 has a threaded texture. The threaded texture further enhances the ground-breaking ability of the insertion end 17, so that the inner column 15 can be drilled into the soil more easily.

[0025] like Figure 1 and Figure 3 As shown, two mounting plates 4 are symmetrically arranged, and the mounting plates 4 include two separate plate bodies 18, one side of the plate bodies 18 is hinged to each other, and a reserved fixing hole 19 is opened on the bottom wall of the plate body 18 away from the center of the base 2, and each plate body 18 has a through groove 7 for the plug-in column 5 to pass through. When the mounting plate 4 is not in use, the mounting plate 4 is stored in the slide groove 3 as a whole and the plug-in column 5 is inserted to limit and fix the mounting plate 4, so that the mounting plate 4 will not fall out, realizing the multi-purpose of the plug-in column 5; there is no hard mounting component on the ground in the installation scene, but there is a hard vertical height When installing components, the mounting plate 4 can be pulled out horizontally, and then the plate body 18 away from the center of the base 2 can be flipped to a vertical state. At this time, the plug-in column 5 is plugged into the through groove 7 of another horizontal plate body 18, so that the fixing holes 19 on the plate body 18 in the vertical state after flipping can be connected and fixed, thereby expanding the installation method of the base 2 to meet the use needs of more occasions. In order to improve the stability of the plate body 18 after flipping, a second magnetic block for adsorbing and fixing the plate body 18 is embedded on the side wall of the base 2, and the plate body 18 is stably maintained in a vertical installation state by means of magnetic adsorption.

[0026] like Figure 1 and Figure 2 As shown, an elastic member 20 is fixedly arranged in the middle of the slide groove 3, and the elastic member 20 is specifically a rubber block. The two sides of the rubber block are used to abut the side walls of the mounting plate 4 to drive the mounting plate 4 to move out of the slide groove 3 away from the center of the base 2. At the same time, a top block 21 is vertically slidably connected to the bottom of the base 2. The top of the top block 21 is the driving end and abuts the elastic member 20. The bottom end portion of the top block 21 protrudes out of the bottom wall of the base 2. In this way, when the base 2 is placed on the ground, the top block 21 is retracted into the base 2 and its top driving end squeezes the rubber block to deform and generate elastic force. At this time, elastic potential energy is accumulated in the rubber block. After the plug-in column 5 is pulled out, the mounting plate 4 will move out of the slide groove 3 on one side under the action of the elastic member 20 to form a fulcrum. At this time, the mounting plate 4 can be pulled out by holding the mounting plate 4 and sliding it out of the end of the slide groove 3, thereby improving the convenience of pulling out the mounting plate 4.

[0027] In this embodiment, the static level 1 has an alarm module inside. When it is detected that the settlement amount at the current detection point exceeds the set limit value, the alarm module will send a signal to the monitoring platform center, so that the staff can get the current situation in time so as to take timely response measures to reduce the corresponding safety risks. In actual use, each subway line settlement monitoring device is fixedly installed at each required detection point. Each subway line settlement monitoring device is connected by a pipeline. The pipeline is filled with detection fluid. The data of each detection point is obtained by the initial monitoring, and the secondary data obtained by subsequent monitoring is compared with the initial data to obtain the corresponding settlement data, thereby finally realizing real-time monitoring of the settlement of the subway line and providing early warning information in time, thereby improving the prevention and control capabilities of settlement disasters and ensuring the safety of subway operations.

[0028] Example 2 A subway line settlement monitoring device, such as Figure 4 As shown, the difference between it and Example 1 mainly lies in the different structure of the plug-in column 5. In this embodiment, a push block 22 is fixed to the outer wall of the inner column 15 of the plug-in column 5, and the top wall of the push block 22 is used to abut the bottom wall of the outer sleeve 14. In this way, when it is necessary to pull out the plug-in column 5 inserted into the ground, the inner column 15 can be moved upward by rotating it in the opposite direction. During the upward movement, the push block 22 simultaneously pushes the outer sleeve 14 upward to achieve the pulling-out effect, which facilitates the pulling-out operation of the plug-in column 5 and avoids the situation where the plug-in column 5 is difficult to pull out.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
