The force dissipation rod slides from the side of the contact plate one close to the contact plate two and passes through the side of the contact plate one away from the contact plate two.

[0033] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0034] 1. The special-shaped beam leveling detection device used in tunnels, when installing the formed special-shaped beam, directly place the two ends of the special-shaped beam on the casting plate to align the two ends of the special-shaped beam. At this time, the special-shaped beam can be further detected and leveled by measuring equipment such as a spirit level. When leveling special-shaped beams of different widths, pull the movable seat away from the casting plate to change the support range of the special-shaped beam, thereby improving the applicability of the device. The splint can limit the front and rear sides of the special-shaped beam to prevent the special-shaped beam from shifting forward and backward during the leveling process and affecting the leveling detection accuracy. After the connecting half pipe is limited by the block, the movable seat and the splint are fixed, and the dead weight of the special-shaped beam makes its installation more stable.

[0035] 2. The special-shaped beam leveling detection device used in tunnels has a support arm that contacts the ground on the front and rear sides of the casting plate through a support plate and a contact plate, which increases the support area of ​​the device and makes the special-shaped beam more stable, thereby improving the stability and leveling efficiency of the entire device. The support arm is erected, and then the card is inserted into the slot. At this time, the card limits the front and rear sides of the support arm. After the support arm is folded, it is convenient to move the device.

[0036] 3. The special-shaped beam leveling detection device used in the tunnel, after the clamping plate is pulled out of the slot, the support arm loses its limit. At this time, the support arm quickly expands through the torsion force of the torsion spring 1 to support the device, which improves the convenience of using the device. The torsion force of the torsion spring 2 drives the support rod to rotate through the torsion shaft 1, but the support rod and the contact plate 2 are in contact with the ground, thereby generating an interaction force with the ground, which improves the supporting strength of the device.

[0037] 4. When the special-shaped beam leveling detection device used in tunnels vibrates due to environmental influences, the vibration force is transmitted to the damping rod through the contact plate and the support rod. The damping rod itself generates friction to reduce the lateral vibration, preventing the device from being affected by the vibration and causing the leveling detection to be inaccurate.

[0038] 5. The special-shaped beam leveling detection device used in the tunnel has an arc-shaped support plate in contact with the damping rod to form a support for the damping rod. After the top end of the damping rod is lifted, the support strength between its bottom end and the resistance block and the ground is increased, so that the damping rod can transmit force to the ground more quickly when dissipating force, thereby improving the shock absorption efficiency of the device. When the resistance plate 1 and the resistance plate 2 are slightly offset by the vibration, the force dissipation rod slides inside the resistance plate 1, thereby reducing the force of the longitudinal vibration of the device, further improving the shock absorption efficiency.

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 7One embodiment of the present invention is: a special-shaped beam leveling detection device for use in tunnels, comprising a base plate 1, the base plate 1 being used to install a jack to support the top of the special-shaped beam, electric telescopic rods 2 being fixedly connected to both sides of the inner surface of the base plate 1, the electric telescopic rods 2, the end of the electric telescopic rods 2 away from the base plate 1 being fixedly connected to a casting plate 3, and the electric telescopic rods 2 being able to drive the casting plate 3 toward or away from the base plate 1, thereby supporting and leveling special-shaped beams of different lengths, the casting plate 3 being used to support both ends of the special-shaped beam, the lower surface of the casting plate 3 being rotatably connected to casters 4, the casters 4 being used to drive the base plate 1 and the casting plate 3 to move, and a spirit level being installed on the surface of the base plate 1. The spirit level is used for leveling detection of special-shaped beams. Support devices 7 are arranged on both sides of the base plate 1. Support devices 7 are used to make the device more stable when pouring and leveling special-shaped beams. Shock absorbers 8 are arranged on both sides of the base plate 1. Shock absorbers 8 are used to reduce the vibration of the device caused by environmental influences. If the formed special-shaped beam is to be installed, the two ends of the special-shaped beam are directly placed on the casting plate 3 to align the two ends of the special-shaped beam. At this time, the special-shaped beam can be further detected and leveled by measuring equipment such as a spirit level. If special-shaped beams of different widths are to be leveled, the movable seat 5 is pulled away from the casting plate 3, thereby changing the support range of the special-shaped beam and improving the applicability of the device. The casting plate 3 includes a connecting half-tube 9, which is slidably connected to the front and rear sides of the inner surface of the casting plate 3. The end of the connecting half-tube 9 away from the casting plate 3 is fixedly connected to a movable seat 5. The movable seat 5 is used to support both ends of the special-shaped beam, and pulling the movable seat 5 away from the casting plate 3 can increase the supporting area of ​​the special-shaped beam, thereby supporting and leveling special-shaped beams of different widths. The upper surface of the movable seat 5 is fixedly connected to a splint 6, which is used to clamp the front and rear sides of the special-shaped beam. A fixing groove 11 is opened on the upper surface of the casting plate 3, and a through groove 12 is opened on the upper surface of the casting plate 3. The casting plate 3 also includes an arc-shaped clip 10, which is fixedly connected to the connecting half-tube 9 The front and rear sides of the upper surface of the arc-shaped card strip 10 are inclined surfaces. The elastic telescopic rod 13 is fixedly connected to the inner surface of the fixed groove 11. The top of the elastic telescopic rod 13 is fixedly connected with a pressure plate 14. The lower surface of the pressure plate 14 is fixedly connected with a clamping block 15. The front and rear sides of the lower surface of the clamping block 15 are inclined surfaces. The caster 4 is fixedly connected to the lower surface of the base plate 1. The clamping block 15 is slidably connected to the inner surface of the through groove 12. The splint 6 can limit the front and rear sides of the special-shaped beam to prevent the special-shaped beam from deviating forward and backward during the leveling process and affecting the leveling detection accuracy. After the connecting half pipe 9 is limited by the clamping block 15, the movable seat 5 and the splint 6 are fixed, and then the installation is more stable through the dead weight of the special-shaped beam.

[0049] Working principle: push the bottom plate 1 and the pouring plate 3, the bottom plate 1 and the pouring plate 3 are moved in the tunnel by the casters 4, and stop when they are pushed to the position where the special-shaped beam needs to be poured and installed, start the electric telescopic rod 2, and the electric telescopic rod 2 pushes the pouring plate 3 away from the bottom plate 1, and stops when the pouring plate 3 contacts the inner walls on both sides of the tunnel. If a special-shaped beam is to be poured, the mold base is placed on the pouring plate 3. If the formed special-shaped beam is to be installed, the two ends of the special-shaped beam are directly placed on the pouring plate 3 to align the two ends of the special-shaped beam. At this time, the special-shaped beam can be further detected and leveled by measuring equipment such as a level. If special-shaped beams of different widths need to be leveled, pull the movable seat 5 away from the pouring plate 3, thereby changing the support range of the special-shaped beam and improving the applicability of the device. When the special-shaped beam is placed on the movable seat 5, the splint 6 can limit the front and rear sides of the special-shaped beam to prevent the special-shaped beam from deviating front and rear during the leveling process and affecting the leveling detection accuracy. In the process of placing the special-shaped beam on the casting plate 3, the bottom end of the special-shaped beam contacts the pressing plate 14 and drives the pressing plate 14 to press down. The pressing plate 14 squeezes the elastic telescopic rod 13 downward, and at the same time drives the clamping block 15 to move downward and insert the clamping block 15 into the connecting half pipe 9. After the clamping block 15 is inserted into the connecting half pipe 9, its front and rear sides are clamped by the arc-shaped clamping strip 10. In turn, the connecting half pipe 9 is limited by the clamping block 15, thereby fixing the movable seat 5 and the splint 6, and utilizing the dead weight of the special-shaped beam to make its installation more stable. If the clamping block 15 contacts the arc-shaped clamping strip 10 when moving downward, the two are deviated by the guidance between the inclined surfaces.

[0050] See also Figure 1-Figure 7The support arm 72 is fixedly mounted on the support frame 71 and the support frame 72 is fixedly mounted on the support frame 71. The support arm 72 is fixedly mounted on the support frame 71 and the support frame 72 is fixedly mounted on the support frame 71. The support device 7 also includes a slot 75, which is opened on the side of the casting plate 3 close to the base plate 1, and the clamping plate 76 is fixedly connected to both sides of the base plate 1. The torsion shaft 1 78 is hinged to the inner surface of the support plate 73, and one end of the torsion shaft 1 78 is fixedly connected to a support rod 77, and the bottom end of the support rod 77 is hinged to a contact plate 2 79. A torsion spring 1 is provided at the hinge between the support arm 72 and the connecting seat 71, and a torsion spring 2 is provided at the hinge between the torsion shaft 1 78 and the support plate 73. After the clamping plate 76 is pulled out of the slot 75, the support arm 72 loses its limit. At this time, the support arm 72 is quickly expanded by the torsion of the torsion spring 1 to support the device, thereby improving the ease of use of the device. The torsion of the torsion spring 2 drives the support rod 77 to rotate through the torsion shaft 1 78, but the support rod 77 and the contact plate 2 79 are in contact with the ground, thereby generating an interaction force with the ground, thereby improving the supporting strength of the device.

[0051] Working principle: During the leveling test of the special-shaped beam, the support arm 72 contacts the ground on the front and rear sides of the casting plate 3 through the support plate 73 and the contact plate 1 74, which increases the support area of ​​the device, makes the special-shaped beam more stable, and thus improves the stability and leveling efficiency of the entire device. When the casting plate 3 is close to and fits the bottom plate 1, the support arm 72 is erected, and then the clamping plate 76 is inserted into the slot 75. At this time, the clamping plate 76 limits the front and rear sides of the support arm 72. After the support arm 72 is retracted, it is convenient to move the device. When the movable seat 5 is far away When leaving the base plate 1, the card plate 76 is pulled out of the slot 75, and after the support arm 72 loses its limit, it is quickly expanded by the torsion of the torsion spring 1 to support the device, thereby improving the ease of use of the device. After the contact plate 1 74 contacts the ground, the bottom end of the support rod 77 hangs down to the bottom surface, thereby driving the contact plate 2 79 to contact the ground. At this time, the torsion of the torsion spring 2 drives the support rod 77 to rotate through the torsion shaft 1 78, but the support rod 77 and the contact plate 2 79 contact the ground, thereby generating an interaction force with the ground, thereby improving the supporting strength of the device.

[0052] See also Figure 1-Figure 7The cam 86 is connected to the upper surface of the support plate 74, and the upper surface of the support plate 74 is hinged with a second torsion shaft 83. The damping rod 82 is fixedly connected to one end of the torsion shaft 83, and the lower end of the damping rod 82 is fixedly connected to a resistance block 84. When the device is affected by the environment and vibrates, the vibration force is transmitted to the damping rod 82 through the resistance plate 74 and the support rod 81. The friction generated by the damping rod 82 itself reduces the lateral vibration, preventing the device from being affected by the vibration and causing the leveling detection to be inaccurate. The shock absorbing device 8 also includes a limiting sleeve 85, which is fixedly connected to both sides of the upper surface of the resistance plate 74, and a push rod 86 is slidably connected to the inner surface of the limiting sleeve 85. The top circumferential surface of the push rod 86 is fixedly connected to a connecting ring 87. The top of the push rod 86 is fixedly connected to an arc-shaped supporting plate 88. The force-dissipating rod 89 is fixedly connected to the resistance plate The second plate 79 is close to the side of the contact plate 1 74, the push rod 86 slides from the upper surface of the contact plate 1 74 to the lower surface of the contact plate 1 74, a spring is provided between the lower surface of the connecting ring 87 and the top of the limiting sleeve 85, the inner arc surface of the arc-shaped supporting plate 88 abuts against the circumferential surface of the damping rod 82, the force-eliminating rod 89 slides from the side of the contact plate 1 74 close to the contact plate 2 79 to the side of the contact plate 1 74 away from the contact plate 2 79, and the arc-shaped supporting plate 88 abuts against the damping rod 82 , forming support for the damping rod 82. After the top end of the damping rod 82 is lifted up, the support strength between its bottom end and the resistance block 84 and the ground is increased, so that the damping rod 82 can transmit the force to the ground more quickly when dissipating force, thereby improving the shock absorption efficiency of the device. When the resistance plate 1 74 and the resistance plate 2 79 are slightly offset by the vibration, the force dissipation rod 89 slides in the resistance plate 1 74, thereby reducing the force of the longitudinal vibration of the device, further improving the shock absorption efficiency.

[0053] Working principle: The downward movement of the contact plate 74 drives the support rod 81 to move downward, and the support rod 81 drives the damping rod 82 and the contact block 84 to move downward, and finally the contact block 84 contacts the ground. When the device is affected by the environment and vibrates, the vibration force is transmitted to the damping rod 82 through the contact plate 74 and the support rod 81. The damping rod 82 itself generates friction to reduce the lateral vibration, preventing the device from being affected by the vibration and causing the leveling detection to be inaccurate. When the contact plate 74 moves downward, it also drives the limit sleeve 85 and the top rod 86 to move downward. When the bottom end of the top rod 86 contacts the ground, it can slide upward relatively in the limit sleeve 85, thereby driving the connection The ring 87 and the arc-shaped support plate 88 move upward. When the contact plate 1 74 contacts the ground, the push rod 86 remains in an upwardly extended state. At this time, the arc-shaped support plate 88 contacts the damping rod 82 to form a support for the damping rod 82. After the top of the damping rod 82 is lifted, the support force between its bottom end and the contact block 84 and the ground is increased, so that the damping rod 82 can transmit the force to the ground more quickly when dissipating force, thereby improving the shock absorption efficiency of the device. When the contact plate 1 74 and the contact plate 2 79 are slightly offset by the vibration, the force dissipation rod 89 slides in the contact plate 1 74, thereby reducing the force of the longitudinal vibration of the device, further improving the shock absorption efficiency.
