Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of monitoring equipment, in particular to a monitoring equipment for tunnel construction. BACKGROUND

[0002] With the continuous advancement of modern engineering construction, tunnel construction is an important part of infrastructure construction and is widely used in transportation, energy, water conservancy and other fields. In the process of tunnel construction, the construction environment is complex and the working conditions are harsh, therefore, in order to ensure construction safety and engineering quality, the installation and use of monitoring equipment become particularly important.

[0003] In the tunnel construction site, the environment is special, the space is narrow and is easily affected by adverse factors, therefore, the installation and arrangement of monitoring equipment has always been a technical problem.

The installation method of the patent and the prior art monitoring equipment both need workers to install them in high places with the help of climbing equipment, which not only makes subsequent maintenance difficult, but also because tunnel construction is a dynamic process, the installation position of the monitoring equipment needs to be adjusted according to the construction progress as the construction deepens, and the equipment needs to be recalibrated or relocated regularly, which brings additional workload to the installation. The current fixed installation method is not convenient to move, for example, if a conventional installation rod is used, the installation rod will seriously interfere with the tunnel construction because the inner wall of the tunnel is arc-shaped, and the installation is limited. Moreover, during the construction of the tunnel, there will be a lot of vibration, which can come from blasting, use of mechanical equipment, vehicle driving, soil and rock movement, etc., especially in the case of large vibration such as blasting, which can cause serious damage to the monitoring equipment.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1, as Figures 1-6 As shown, a monitoring device for tunnel construction includes a base pole 1, an elastic inner pole 2 is provided on the top of the base pole 1, an installation head 3 is provided on the top of the elastic inner pole 2, a monitoring device 4 is installed on the installation head 3, a plurality of outer snake tubes 5 are provided between the installation head 3 and the base pole 1, and a hinge seat 6 is provided on the top of both the outer snake tubes 5 and the base pole 1. The hinge seat 6 hinges the plurality of outer snake tubes 5, the base pole 1 and the installation head 3 together, and the outer snake tubes 5 are sleeved on the outside of the elastic inner pole 2.

[0030] Two sets of guide slides 61 are provided on the left side of the hinge seat 6, and two sets of hydraulic cylinders 62 are fixedly installed on the right side of the hinge seat 6. The two sets of hydraulic cylinders 62 are provided with telescopic piston rods 63 inside. The telescopic piston rods 63 penetrate into the interior of the hinge seat 6, and a triangular wedge block 65 is fixedly installed at one end inside the hinge seat 6. The triangular wedge block 65 is slidably connected in the guide slides 61. The two sets of triangular wedge blocks 65 are located at the front end and rear end of the hinge of the outer snake bone tube 5, respectively.

[0031] During installation, firmly attach and secure the bottom rod 1 against the bottom of the tunnel wall, then bend the entire assembly as shown in the attached figure. Figure 6 As shown in the diagram, the telescopic piston rod 63 on the outer side of the bend is then controlled to retract. The telescopic piston rod 63 drives the triangular wedge block 65 to insert between the adjacent outer snake bone tubes 5, restricting the elastic inner rod 2 from returning to its original position. The entire device is in a bent shape. Then, the monitoring equipment 4 is installed on the mounting head 3. After installation, the telescopic piston rod 63 on the outer side of the bend is controlled to extend. The telescopic piston rod 63 drives the triangular wedge block 65 away from the outer snake bone tube 5. Under the elastic force of the elastic inner rod 2, the elastic inner rod 2 swings towards the inner wall of the tunnel until the outer snake bone tube 5 is tightly attached to the inner wall of the tunnel. Using this method, the device can be used for installation in tunnels of different specifications without the need for climbing for installation. The installation is convenient. When relocating the device, it is only necessary to remove the bottom rod 1 from the inner wall of the tunnel and re-fix it in the relocation position.

[0032] Then according to the current construction environment, the telescopic piston rod 63 on the bending inner side is controlled to retract, the telescopic piston rod 63 drives the triangular wedge 65 to be inserted between the adjacent outer snake bone barrels 5, but does not touch the top of the outer snake bone barrel 5, and there is a certain spacing between the outer snake bone barrel 5, which is a damping spacing. Because the elastic inner rod 2 gives the device a spring force towards the outside of the tunnel, the outer snake bone barrels 5 on the bending outer side are locked by the triangular wedge 65, so the elastic inner rod 2 can only bend inward, and the gravity of the monitoring device 4 makes the elastic inner rod 2 have a tendency to bend inward, so there is a certain damping spacing on the bending inner side, which can dampen the monitoring device 4. Compared with the existing spring damping, the vibration energy is absorbed and consumed by the bending deformation of the elastic inner rod 2. Compared with the elastic recovery of the spring, this deformation mode is more smooth and stable. During the deformation process of the elastic bending rod, the vibration is gradually consumed slowly, and the damping effect is more stable and less likely to produce a rebound effect.

[0033] When the tunnel is subjected to blasting and other intense construction, the smaller damping distance cannot achieve a safe damping effect, and the monitoring device 4 is easily damaged by vibration. Therefore, at this time, the triangular wedge 65 on the bending inner side is controlled to be completely away from the outer snake bone barrel 5, and the elastic inner rod 2 bends inward without any restriction. The damping distance is much larger than the conventional damping distance, so that the monitoring device 4 will not be damaged even in a dangerous environment such as blasting.

[0034] During maintenance, the triangular wedge 65 on the bending inner side is controlled to be completely away from the outer snake bone barrel 5, and the triangular wedge 65 on the bending outer side is controlled to continue to be inserted between the adjacent outer snake bone barrels 5, to drive the elastic inner rod 2 to bend, and the device as a whole bends into a state Figure 6 without the need to climb for maintenance, which is convenient and efficient.

[0035] In the above embodiment, the bottom rod 1 is further sleeved with a wall-hanging base 7.

[0036] Further, the wall-hanging base 7 is fixedly installed on the inner wall of the tunnel by bolts.

[0037] Through the setting of the wall-hanging base 7, the bottom rod 1 can not be placed on the bottom surface of the tunnel, and can be fixed at any position on the inner wall of the tunnel. The installation height of the monitoring device 4 can be adjusted as needed, and the bottom rod 1 is away from the ground, which is convenient for wiring and safer. In this embodiment, the wall-hanging base 7 is fixedly installed by bolts, which is more secure.

[0038] In the above embodiment, the wall-hanging base 7 is further fixedly installed on the inner wall of the tunnel by bolts. In this embodiment, the wall-hanging base 7 is fixedly installed by bolts, which is more secure.

[0039] In the above embodiment, the bottom rod 1 is provided with a control hydraulic cylinder 9 on both sides, and the two control hydraulic cylinders 9 are connected to the hydraulic cylinders 62 at the front and rear ends of the hinge seats 6 of all the outer snake bone cylinders 5 through the hydraulic pipes 10. The hydraulic cylinder 62 is connected to the hydraulic cylinder 62 at one end close to the hinge seat 6, and the top spring 64 is arranged between the telescopic piston rod 63 and the inner wall of the hydraulic cylinder 62. The top spring 64 is used to push the telescopic piston rod 63 to extend. The control hydraulic cylinder 9 is provided with a sealing nut 91 at the top, and the inside of the control hydraulic cylinder 9 is provided with a piston. The top of the piston is provided with a piston screw 92 which is screwed into the sealing nut 91.

[0040] Further, the top of the piston screw 92 is provided with a rotating handle.

[0041] The piston screw 92 is rotated by the rotating handle. When the piston screw 92 is rotated downward, the hydraulic oil in the control hydraulic cylinder 9 enters the hydraulic cylinder 62 through the hydraulic pipe 10, and the hydraulic oil pushes the telescopic piston rod 63 to retract. When the piston screw 92 is rotated upward, the top spring 64 pushes the telescopic piston rod 63 to extend. The setting of the two control hydraulic cylinders 9 can control the extension and retraction of the telescopic piston rod 63 on the outer side and the inner side respectively, and the control is simple.

[0042] In the above embodiment, the bottom rod 1 is provided with a control hydraulic cylinder 9 on both sides, and the two control hydraulic cylinders 9 are connected to the hydraulic cylinders 62 at the front and rear ends of the hinge seats 6 of all the outer snake bone cylinders 5 through the hydraulic pipes 10. The hydraulic cylinder 62 is connected to the hydraulic cylinder 62 at one end close to the hinge seat 6, and the top spring 64 is arranged between the telescopic piston rod 63 and the inner wall of the hydraulic cylinder 62. The top spring 64 is used to push the telescopic piston rod 63 to extend. The control hydraulic cylinder 9 is provided with a sealing nut 91 at the top, and the inside of the control hydraulic cylinder 9 is provided with a piston. The top of the piston is provided with a piston screw 92 which is screwed into the sealing nut 91.

[0043] Through the setting of the detachable support 8 and the quick connector 101, the control hydraulic cylinder 9 can be arranged separately. After installation, the device can be removed, reducing the overall space occupied by the device.

[0044] In the above embodiment, the bottom rod 1 is provided with a control hydraulic cylinder 9 on both sides, and the two control hydraulic cylinders 9 are connected to the hydraulic cylinders 62 at the front and rear ends of the hinge seats 6 of all the outer snake bone cylinders 5 through the hydraulic pipes 10. The hydraulic cylinder 62 is connected to the hydraulic cylinder 62 at one end close to the hinge seat 6, and the top spring 64 is arranged between the telescopic piston rod 63 and the inner wall of the hydraulic cylinder 62. The top spring 64 is used to push the telescopic piston rod 63 to extend. The control hydraulic cylinder 9 is provided with a sealing nut 91 at the top, and the inside of the control hydraulic cylinder 9 is provided with a piston. The top of the piston is provided with a piston screw 92 which is screwed into the sealing nut 91.

[0045] Through the design, when the triangular wedge block 65 is inserted between the adjacent outer snake bone cylinders 5, the elastic inner rod 2 can be limited between the outer snake bone cylinders 5. When the triangular wedge block 65 is away from the outer snake bone cylinder 5, the telescopic piston rod 63 limits the elastic inner rod 2 between the outer snake bone cylinders 5, which can correct the overall bending of the elastic inner rod 2, so that the bending of the outer snake bone cylinder 5 can be synchronized with the bending of the elastic inner rod 2, and the overall stability is high.

[0046] In the above embodiment, the bottom rod 1 is provided with a control hydraulic cylinder 9 on both sides, and the two control hydraulic cylinders 9 are connected to the hydraulic cylinders 62 at the front and rear ends of the hinge seats 6 of all the outer snake bone cylinders 5 through the hydraulic pipes 10.

The control hydraulic cylinder 9 is provided with a sealing nut 91 at the top, and the inside of the control hydraulic cylinder 9 is provided with a piston.

[0047] Further, the outside of the mounting head 3 is provided with a mounting positioning groove, and the hoop 41 is sleeved in the mounting positioning groove.

[0048] Through the setting of the hoop 41 and the mounting positioning groove, the monitoring device 4 can be more quickly and stably fixed on the mounting head 3, and the mounting effect is good.
