DETAILED DESCRIPTION

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0033] Example:

[0034] See also Figures 1 to 3 , a monitoring point layout structure, this embodiment is applied to the monitoring point layout on the tunnel wall.

[0035] A monitoring point arrangement structure includes a first mounting seat 1 and a monitoring point base 2 arranged on a structure to be measured. In this embodiment, the first mounting seat 1 is installed on a tunnel wall through a first screw 1.3; the first mounting seat 1 includes a clamping mechanism 1.1, and the monitoring point base 2 is provided with a limit seat 2.1 that cooperates with the clamping mechanism 1.1. By inserting the limit seat 2.1 into the clamping mechanism 1.1, the monitoring point base 2 can be quickly installed and disassembled. Figure 1 As shown, it is convenient to disassemble, assemble and maintain the monitoring point base 2, thereby improving work efficiency.

[0036] The clamping mechanism 1.1 comprises a first mounting block 1.1.1 and a pull rod 1.1.2 movably connected to the first mounting block 1.1.1, an elastic member 1.1.3 is arranged between the pull rod 1.1.2 and the first mounting block 1.1.1; one end of the pull rod 1.1.2 is provided with a pressing plate 1.1.4 cooperating with a limit seat 2.1 to achieve clamping of the monitoring point base 2. In this embodiment, the pull rod 1.1.2 is arranged through the first mounting block 1.1.1, and both ends of the pull rod 1.1.2 exceed the first mounting block 1. 1.1, the elastic member 1.1.3 is arranged at one end of the pull rod 1.1.2, the two ends of the elastic member 1.1.3 are respectively against or connected to the pull rod 1.1.2 and the first mounting block 1.1.1, and a pressure plate 1.1.4 is arranged at the end of the pull rod 1.1.2 away from the elastic member 1.1.3, and the pressure plate 1.1.4 is stuck in the limit seat 2.1 of the horizontal rod 2.3 of the monitoring point base 2, and the elastic force of the elastic member 1.1.3 is used to press the horizontal rod 2.3 to prevent the monitoring point base 2 from escaping from the first mounting seat 1.

[0037] The first mounting block 1.1.1 and the pull rod 1.1.2 are in a sliding connection that can rotate relative to each other. In this embodiment, the matching part of the pull rod 1.1.2 and the first mounting block 1.1.1 is a cylindrical structure. The pull rod 1.1.2 can slide in the height direction on the first mounting block 1.1.1 and can also rotate relative to the first mounting block 1.1.1, so as to facilitate rotating the pull rod 1.1.2 when installing the monitoring point base 2, thereby preventing the pressure plate 1.1.4 from blocking the first mounting groove 1.2 on the first mounting block 1.1.1, making it inconvenient to insert the first plug block 2.2.

[0038] The pressing plate 1.1.4 is provided with a handle 1.1.5, which is convenient for the operator to lift and rotate the pull rod 1.1.2, so that the pull rod 1.1.2 and the first mounting block 1.1.1 can achieve relative movement, thereby completing the installation and pressing of the monitoring point base 2.

[0039] The elastic member 1.1.3 is sleeved on the pull rod 1.1.2, the telescopic direction of the elastic member 1.1.3 is consistent with the sliding direction of the pull rod 1.1.2, one end of the elastic member 1.1.3 is connected to or abuts against the pull rod 1.1.2, and the other end of the elastic member 1.1.3 is connected to or abuts against the first mounting block 1.1.1; see Figure 2 When the elastic member 1.1.3 is arranged on the top surface of the first mounting block 1.1.1, one end of the elastic member 1.1.3 can be connected to the pressure plate 1.1.4, and the other end of the elastic member 1.1.3 can be connected to the top surface of the first mounting block 1.1.1. The elastic member 1.1.3 applies tension to the pressure plate 1.1.4 (that is, the initial state of the elastic member 1.1.3 is in a stretched state) to achieve compression of the monitoring point base 2; when the elastic member 1.1.3 is arranged on the bottom surface of the first mounting block 1.1.1, the two ends of the elastic member 1.1.3 respectively abut against or are connected to the bottom surface of the first mounting block 1.1.1 and the limiting surface of the bottom end of the pull rod 1.1.2, and the elastic member 1.1.3 applies pressure to the limiting surface of the bottom end of the pull rod 1.1.2 (that is, the initial state of the elastic member 1.1.3 is in a compressed state) to achieve compression of the monitoring point base 2; see Figure 2 In this embodiment, the elastic member 1.1.3 is a spring, and the elastic member 1.1.3 is arranged on the bottom surface of the first mounting block 1.1.1 to avoid affecting the clamping effect of the clamping mechanism 1.1 on the horizontal rod 2.3 when the height specification of the elastic member 1.1.3 is greater than the height specification of the horizontal rod 2.3.

[0040] See also Figure 2 The first mounting seat 1 also includes a first mounting groove 1.2. The monitoring point base 2 is provided with a first plug block 2.2 matching the first mounting groove 1.2 to realize the installation of the monitoring point base 2, improve the connection reliability between the monitoring point base 2 and the first mounting seat 1, and prevent the monitoring point base 2 from falling due to failure of the clamping mechanism 1.1. In order to ensure the installation and positioning accuracy of the monitoring point base 2, the cross-section of the first mounting groove 1.2 along the insertion direction can be selected from a non-circular shape to avoid the first plug block 2.2 from rotating in the first mounting groove 1.2 and affecting the installation accuracy of the monitoring point base 2. In this embodiment, the cross-section of the first mounting groove 1.2 along the insertion direction is rectangular.

[0041] See also Figure 1 and Figure 3A monitoring point layout structure also includes a support seat 3 and a second mounting seat 4; the support seat 3 is movably connected to the monitoring point base 2 to achieve balanced support for the monitoring point base 2. In this embodiment, the support seat 3 and the monitoring point base 2 are hinged to form a triangular stable support structure. The second mounting seat 4 is installed on the structure to be measured (i.e., the tunnel wall) through a second screw 4.3. The second mounting seat 4 is movably connected to the support seat 3 to achieve the installation of the support seat 3.

[0042] The second mounting seat 4 is provided with a second mounting groove 4.1, and the support seat 3 is provided with a second plug-in block 3.1 matching the second mounting groove 4.1, so as to realize the rapid installation and removal of the support seat 3.

[0043] The support seat 3 includes a support rod 3.4, and the two ends of the support rod 3.4 are respectively provided with a first hinge seat 3.2 and a second hinge seat 3.3 connected to the monitoring point base 2 and the second plug block 3.1, so as to adjust the support angle of the support seat 3 according to the tunnel wall structure, and the installation position of the second mounting seat 4 should be determined according to the support angle of the support seat 3, so that the horizontal rod 2.3 of the monitoring point base 2 and the monitoring point located on the horizontal rod 2.3 are always in a horizontal state.

[0044] The method of using the above monitoring point layout structure is as follows: according to the setting position of the tunnel monitoring point, the first mounting seat 1 and the second mounting seat 4 are installed on the tunnel wall, and the hinged monitoring point base 2 and the support seat 3 are connected to the first mounting seat 1 and the second mounting seat 4. When installing the monitoring point base 2, by turning the handle 1.1.5, the pressure plate 1.1.4 is adjusted to a position that does not overlap with the first installation groove 1.2, and the first plug block 2.2 is inserted into the first installation groove 1.2, and the handle 1.1.5 is lifted and turned to make the pressure plate 1.1.4 above the limit seat 2.1 and then released. The pressure plate 1.1.4 is inserted into the limit seat 2.1 to press the horizontal rod 2.3, and the monitoring point base 2 can be installed on the first mounting seat 1; when installing the support seat 3, adjust the position of the support seat 3 so that the second plug block 3.1 is inserted into the second mounting groove 4.1, and the support seat 3 can be installed on the second mounting seat 4, and the measurement of the tunnel wall monitoring point can be started; when the monitoring point base 2 needs to be dismantled or maintained, the pressure plate 1.1.4 is disengaged from the limit seat 2.1 by lifting and turning the handle 1.1.5, and the first plug block 2.2 and the second plug block 3.1 can be pulled out.
