Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and particularly to a mobile construction protection device for tunnel construction. Background Art

[0002] Tunnel construction is an extremely complex large-scale project and is extremely dangerous at the same time. Safety is the biggest problem in tunnel construction, and safety accidents occur frequently. The safety protection of tunnel construction is the key research direction for engineering technicians. Improving safety protection is extremely important for construction workers and plays a decisive role in tunnel construction.

[0003] When constructing rail transit in a tunnel, in order to prevent the adverse effects of mud and stones falling from the tunnel top on construction workers and construction equipment, it is usually necessary to set up a protection device in the construction section to protect construction workers and construction equipment. The existing mobile construction protection device usually moves the protection device to a predetermined position through a moving component. After reaching the construction position, the protection device is stably fixed on the tunnel ground through a reinforcement component, and the baffle is lifted to the tunnel top, thereby protecting the construction area.

[0004] Due to the complex environment in the tunnel, there will be slight settlement deformation on the tunnel top, and the vibration generated during the construction process will cause mud and stones to fall from the tunnel top at any time, and even partial collapse may occur. The mud and stones will squeeze the baffle, causing deformation at the top of the baffle. The accumulated mud and stones will squeeze the baffle, causing the baffle to be subjected to a large pressure. When the pressure value reaches the maximum value, the protection device will be damaged, which will cause harm to construction workers, making the tunnel construction lack safe and reliable protection. With the development of technology, some mobile construction protection devices are provided with a monitoring module, which can monitor the pressure of the protection device and give a reminder. However, in the new technology, only the protection device is monitored, and it is difficult to make corresponding adjustments to the protection device according to the corresponding monitoring data, making the protection device not flexible enough and difficult to effectively protect the construction area.

When the protection device is affected by an external force or deforms itself, the displacement sensor can accurately capture these tiny position changes. The displacement sensor is a resistive displacement sensor. The resistive displacement sensor reflects the displacement of an object by measuring the change in resistance value.

[0027] Furthermore, the pressure monitoring module 5 includes a pressure sensor, the pressure sensor is fixedly installed at the bottom of the shielding plate 3, the pressure sensor is connected to the processor.

[0028] Further, a deformation monitoring module 4 is provided at the top of the baffle 3 and a pressure monitoring module 5 is provided at the bottom of the baffle 3. In the initial state, the pressure monitoring module 5 monitors the pressure value at the top of the tunnel. When the pressure value exceeds the first threshold range, the deformation monitoring module 4 monitors the displacement deformation amount at the top of the baffle 3. When the displacement deformation amount exceeds the set value, the processor controls the alarm 8 to issue a first-level alarm. At the same time, the processor controls the lifting unit 2 to operate, so that the baffle 3 is lifted upward to support the top of the tunnel and prevent partial collapse. After the baffle 3 is lifted and supported, the first-level alarm stops. The pressure monitoring module 5 continues to monitor the pressure at the top of the baffle 3.

[0029] As shown in the attached Figure 1-7 figures, it includes: A reinforcement unit 1, which is used to fix the protection device; A lifting unit 2, which is arranged on the reinforcement unit 1; A baffle 3, which is arranged above the lifting unit 2, and the lifting unit 2 is used to control the lifting and lowering of the baffle 3; A deformation monitoring module 4, which is installed on the baffle 3 and is used to monitor the displacement deformation amount at the top of the baffle 3; A pressure monitoring module 5, which is installed at the bottom of the baffle 3 and is used to monitor the bearing pressure value of the baffle 3; An alarm 8, which is installed on the protection device; A processor, which is connected to the lifting unit 2, the deformation monitoring module 4, the pressure monitoring module 5 and the alarm 8. The processor controls the operation of the lifting unit 2 and the alarm 8 according to the displacement deformation amount and the bearing pressure value.

[0030] Further, buffer units 6 are respectively arranged on both sides of the baffle 3. The buffer unit 6 includes: A baffle 61, the top of which is rotatably connected to the baffle 3; A fixed seat 62, which is fixedly connected to the inner side of the baffle 61; Fixed rods 63, which are arranged in two groups and symmetrically arranged on both sides of the fixed seat 62; A pulley 64, the pulley 64 is fixedly connected to one side of the fixing rod 63, and the pulley 64 is slidably connected in the fixing seat 62; The connecting block 65 has one end fixedly connected to the other side of the fixing rod 63 , and the other end of the connecting block 65 is fixedly connected to the supporting rod 21 .

[0031] Furthermore, a slide groove 621 is respectively provided on both sides of the fixed seat 62, and a pulley 64 is slidably connected in the slide groove 621. When the shielding plate 3 is driven downward by the lifting unit 2 to unload the accumulated mud and rocks, the downward movement of the shielding plate 3 can drive the baffle 61 to move downward, and then drive the pulley 64 on the fixed rod 63 to slide on the fixed seat 62. When the pulley 64 slides on the inclined part of the slide groove 621, the fixed rod 63 can drive the baffle 61 to deflect outward, so that the shielding plate 3 can simultaneously drive the baffle 61 to deflect a certain angle during the downward movement, so that when the mud and rocks slide off the shielding plate 3, they can be buffered by the deflected baffle 61, thereby slowing down the speed of the mud and rocks falling, avoiding the problem that the mud and rocks fall directly from the shielding plate 3 and cause a large impact force, which may easily cause damage to personnel and equipment in the construction area.

[0032] Furthermore, a moving component 7 is provided at the bottom of the support rod 21. The moving component 7 is used to move the protective device to the construction position. The moving component 7 includes a base and a roller. The roller is rotatably connected to the base and can be driven to move by an external traction device, thereby driving the protective device to move.

[0033] Working principle: The protective device is moved to the construction area through the moving component 7, and the lifting rod 22 is driven to move upward through the hydraulic system, thereby driving the bearing frame 23 and the shielding plate 3 to move upward until the shielding plate 3 contacts the top of the tunnel. At the same time, the pressure monitoring module 5 monitors the pressure at the top of the tunnel. When the monitored pressure value exceeds the first threshold range, the deformation monitoring module 4 monitors the displacement deformation of the top of the shielding plate 3. When the displacement deformation exceeds the set value, the processor controls the alarm 8 to issue a first-level alarm. At the same time, the processor controls the lifting unit 2 to operate, so that the shielding plate 3 is lifted upward to support the top of the tunnel to prevent partial area collapse. When the shielding plate 3 is lifted and supported, the first-level alarm stops, and the pressure monitoring module 5 continues to monitor the pressure on the top of the shielding plate 3. When the monitored pressure value exceeds the second threshold range, the processor controls the alarm 8 to issue a second-level alarm, and at the same time, the processor controls the lifting unit 2 to move the shielding plate 3 downward to unload the mud and rocks accumulated on the top of the shielding plate 3; When the baffle 3 moves downward, it can drive the baffle 61 to move downward, and then drive the pulley 64 on the fixed rod 63 to slide on the fixed seat 62. When the pulley 64 slides on the inclined part of the chute 621, the fixed rod 63 can drive the baffle 61 to deflect outward, so that the baffle 61 can be driven to deflect a certain angle while the baffle 3 moves downward. When the mud and stones slide down from the baffle 3, they can pass through the deflected baffle 61 for buffering and deceleration, so that the fallen mud and stones fall on both sides of the tunnel, protecting the construction personnel and equipment below the protection device.
