[0015] The present invention adopts the above technical solutions, and can bring the following beneficial effects: 1. For the special-shaped beam leveling detection device in the tunnel, when installing the formed special-shaped beam, directly place the two ends of the special-shaped beam on the casting plate and 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. When leveling special-shaped beams with different widths, pull the movable seat away from the casting plate to change the support range for the special-shaped beam, improving the applicability of the device. The clamping plate can limit the front and rear sides of the special-shaped beam to prevent the special-shaped beam from shifting back and forth during the leveling process, which affects the leveling detection accuracy. After the connecting half-tube is limited by the clamping block, the movable seat and the clamping plate are fixed, and then the installation of the special-shaped beam is made more stable due to its own weight.

[0016] 2. For the special-shaped beam leveling detection device in the tunnel, the support arms contact the ground on the front and rear sides of the casting plate through the support plate and the first contact plate, increasing the support area of the device, making the special-shaped beam more stable, thereby improving the stability and leveling efficiency of the overall device. Raise the support arms, and then insert the clamping plate into the slot. At this time, the clamping plate limits the front and rear sides of the support arms, and it is convenient to move the device after retracting the support arms.

[0017] 3. For the special-shaped beam leveling detection device in the tunnel, after the clamping plate is pulled out of the slot, the support arms are no longer limited. At this time, the support arms quickly unfold under the torque of the first torsion spring to support the device, improving the convenience of using the device. The torque of the second torsion spring drives the support rod to rotate through the first torsion shaft, but the support rod and the second contact plate contact the ground, thereby generating a mutual force with the ground, improving the support strength of the device.

[0018] 4. When the special-shaped beam leveling detection device for the tunnel is affected by the environment and vibrates, the vibration force is transmitted to the damping rod through the first contact plate and the support rod. The damping rod generates friction by itself to reduce the lateral vibration, preventing the leveling detection of the device from being inaccurate due to vibration.

[0019] 5. For the special-shaped beam leveling detection device in the tunnel, the arc-shaped supporting plate abuts against the damping rod to form a support for the damping rod. After the top end of the damping rod is lifted, the supporting force between its bottom end and the contact block and the ground is increased, so that the damping rod can transmit the force to the ground more quickly when dissipating the force, thereby improving the shock absorption efficiency of the device. When the first contact plate and the second contact plate are slightly offset under the influence of vibration, the force dissipation rod slides in the first contact plate, thereby reducing the longitudinal vibration force of the device and further improving the shock absorption efficiency.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1 - 7, an embodiment of the present invention is: a special-shaped beam leveling detection device for use in a tunnel, including a bottom plate 1 for installing a jack to support the top of the special-shaped beam. On both sides of the inner surface of the bottom plate 1, electric telescopic rods 2 are fixedly connected. The electric telescopic rods 2 can drive a casting plate 3 to approach or move away from the bottom plate 1 to support and level special-shaped beams of different lengths. The casting plate 3 is used to support both ends of the special-shaped beam. A caster 4 is rotatably connected to the lower surface of the casting plate 4 for driving the bottom plate 1 and the casting plate 3 to move. A level is installed on the surface of the bottom plate 1, and the level is used for the leveling detection of the special-shaped beam. Support devices 7 are arranged on both sides of the bottom plate 1 to make the device more stable when casting and leveling the special-shaped beam. Shock-absorbing devices 8 are arranged on both sides of the bottom plate 1 to reduce the vibration generated by the device affected by the environment. When installing the formed special-shaped beam, directly place both ends of the special-shaped beam on the casting plate 3 to align both ends of the special-shaped beam. At this time, the special-shaped beam can be further detected and leveled by measuring devices such as a level. When leveling special-shaped beams of different widths, pull the movable seat 5 away from the casting plate 3 to change the support range for the special-shaped beam, improving the applicability of the device. The casting plate 3 includes a connecting half-tube 9 slidably connected to the front and rear sides of the inner surface of the casting plate 3. One end of the connecting half-tube 9 away from the casting plate 3 is fixedly connected to a movable seat 5 for supporting both ends of the special-shaped beam. Pulling the movable seat 5 away from the casting plate 3 can increase the support area for the special-shaped beam, thereby supporting and leveling special-shaped beams of different widths. A clamping plate 6 is fixedly connected to the upper surface of the movable seat 5 for clamping both 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 further includes an arc-shaped clamping strip 10 fixedly connected to the upper surface of the connecting half-tube 9, and the front and rear sides of the upper surface of the arc-shaped clamping strip 10 are inclined surfaces. An elastic telescopic rod 13 is fixedly connected to the inner surface of the fixing groove 11, and the top of the elastic telescopic rod 13 is fixedly connected to a pressing plate 14. A clamping block 15 is fixedly connected to the lower surface of the pressing plate 14, and 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 bottom plate 1, and the clamping block 15 is slidably connected to the inner surface of the through groove 12. The clamping plate 6 can limit both sides of the special-shaped beam to prevent the special-shaped beam from shifting forward and backward during the leveling process, affecting the leveling detection accuracy. After the connecting half-tube 9 is limited by the clamping block 15, the movable seat 5 and the clamping plate are fixed, and then the installation is made more stable by the self-weight of the special-shaped beam.

[0024] Working principle: Push the bottom plate 1 and the casting plate 3. The bottom plate 1 and the casting plate 3 move in the tunnel through the casters 4 and stop when they are pushed to the position where special-shaped beams need to be cast and installed. Then start the electric telescopic rod 2. The electric telescopic rod 2 pushes the casting plate 3 away from the bottom plate 1 and stops when the casting plate 3 contacts the inner walls on both sides of the tunnel. When casting a special-shaped beam, place the mold base on the casting plate 3. When installing the formed special-shaped beam, directly place the two ends of the special-shaped beam 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 level. When leveling special-shaped beams with different widths, pull the movable seat 5 away from the casting plate 3 to change the support range for the special-shaped beam, improving the applicability of the device. After the special-shaped beam is placed on the movable seat 5, the clamping plate 6 can limit the front and rear sides of the special-shaped beam to prevent the special-shaped beam from shifting back and forth during leveling, which affects the leveling detection accuracy. During the process of placing the special-shaped beam on the casting plate 3, the bottom end of the special-shaped beam contacts the pressure plate 14 and drives the pressure plate 14 to press down. The pressure plate 14 squeezes the elastic telescopic rod 13 downward and simultaneously drives the clamping block 15 to move downward and insert the clamping block 15 into the connecting half-tube 9. After the clamping block 15 is inserted into the connecting half-tube 9, its front and rear sides are clamped by the arc-shaped clamping strips 10. On the contrary, the connecting half-tube 9 is limited by the clamping block 15, so that the movable seat 5 and the clamping plate 6 are fixed, making the installation more stable by using the self-weight of the special-shaped beam. When the clamping block 15 moves downward and contacts the arc-shaped clamping strip 10, they deviate from each other through the guiding of the inclined surfaces.

[0025] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, the support device 7 includes a connecting seat 71 fixedly connected to the upper surface of the casting plate 3. On both sides of the connecting seat 71, there are articulated support arms 72. A support plate 73 is fixedly connected to the end of the support arm 72 away from the connecting seat 71. A first abutting plate 74 is fixedly connected to the bottom end of the support plate 73. The first abutting plate 74 abuts against the bottom surface of the tunnel to support the whole device. The support arm 72 contacts the ground on the front and back sides of the casting plate 3 through the support plate 73 and the first abutting plate 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 whole device. When 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 back sides of the support arm 72. After the support arm 72 is retracted, it is convenient to move the device. The support device 7 further includes a slot 75 opened on the side of the casting plate 3 close to the bottom plate 1. The clamping plate 76 is fixedly connected to both sides of the bottom plate 1. A first torsion shaft 78 is articulated on the inner surface of the support plate 73. One end of the first torsion shaft 78 is fixedly connected to a support rod 77. The bottom end of the support rod 77 is articulated with a second abutting plate 79. A first torsion spring is provided at the articulated part of the support arm 72 and the connecting seat 71, and a second torsion spring is provided at the articulated part of the first torsion shaft 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 quickly unfolds through the torsion force of the first torsion spring to support the device, which improves the convenience of use of the device. The torsion force of the second torsion spring drives the support rod 77 to rotate through the first torsion shaft 78, but the support rod 77 and the second abutting plate 79 contact the ground, so that an interaction force is generated with the ground, which improves the support strength of the device.

[0026] Working principle: During the leveling detection of the special-shaped beam, the support arm 72 contacts the ground on the front and back sides of the casting plate 3 through the support plate 73 and the first abutting plate 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 whole device. When the casting plate 3 approaches 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 back 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 moves away from the bottom plate 1, the clamping plate 76 is pulled out of the slot 75, and after the support arm 72 loses its limit, it quickly unfolds through the torsion force of the first torsion spring to support the device, which improves the convenience of use of the device. After the first abutting plate 74 contacts the ground, the bottom end of the support rod 77 drops vertically towards the bottom surface, thereby driving the second abutting plate 79 to contact the ground. At this time, the torsion force of the second torsion spring drives the support rod 77 to rotate through the first torsion shaft 78, but the support rod 77 and the second abutting plate 79 contact the ground, so that an interaction force is generated with the ground, which improves the support strength of the device.

[0027] Please refer to Figures 1 - 7, on the basis of the above embodiments, in another embodiment of the present invention, the shock absorption device 8 includes a support rod 81, the support rod 81 is fixedly connected to both ends of the upper surface of the first contact plate 74, the inner surface of the top end of the support rod 81 is hinged with a second torsion shaft 83, the damping rod 82 is fixedly connected to one end of the second torsion shaft 83, the bottom end of the damping rod 82 is fixedly connected with a contact block 84. When the device vibrates due to environmental influence, the vibration force is transmitted to the damping rod 82 through the first contact plate 74 and the support rod 81. The damping rod 82 generates friction by itself to reduce the lateral vibration, preventing the leveling detection of the device from being inaccurate due to vibration. The shock absorption device 8 further includes a limit sleeve 85, the limit sleeve 85 is fixedly connected to both sides of the upper surface of the first contact plate 74, the ejector rod 86 is slidably connected to the inner surface of the limit sleeve 85, a connecting ring 87 is fixedly connected to the circumferential surface of the top of the ejector rod 86, the top end of the ejector rod 86 is fixedly connected with an arc-shaped support plate 88, a force-absorbing rod 89 is fixedly connected to the side of the second contact plate 79 close to the first contact plate 74, the ejector rod 86 slides through the upper surface of the first contact plate 74 and penetrates out of the lower surface of the first contact plate 74, a spring is arranged between the lower surface of the connecting ring 87 and the top end of the limit sleeve 85, the inner arc surface of the arc-shaped support plate 88 abuts against the circumferential surface of the damping rod 82, the force-absorbing rod 89 slides through the side of the first contact plate 74 close to the second contact plate 79 and penetrates out of the side of the first contact plate 74 away from the second contact plate 79, the arc-shaped support plate 88 abuts against the damping rod 82 to form a support for the damping rod 82. After the top end of the damping rod 82 is lifted, the supporting 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 absorbing force, thereby improving the shock absorption efficiency of the device. When the first contact plate 74 and the second contact plate 79 are slightly offset due to vibration, the force-absorbing rod 89 slides in the first contact plate 74, thereby reducing the force of the longitudinal vibration of the device and further improving the shock absorption efficiency.

[0028] Working principle: During the downward movement of the first contact plate 74, the support rod 81 is driven to move downward. 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 vibrates due to environmental influence, the vibration force is conducted to the damping rod 82 through the first contact plate 74 and the support rod 81. The damping rod 82 generates friction by itself to reduce the lateral vibration, preventing the leveling detection of the device from being inaccurate due to vibration. While the first contact plate 74 moves downward, it also drives the limit sleeve 85 and the ejector rod 86 to move downward. When the bottom end of the ejector rod 86 contacts the ground, it can slide upward relative to the limit sleeve 85, thereby driving the connecting ring 87 and the arc-shaped support plate 88 to move upward. When the first contact plate 74 contacts the ground, the ejector rod 86 remains in the upward extended state. At this time, the arc-shaped support plate 88 abuts against the damping rod 82 to form a support for the damping rod 82. After the top end of the damping rod 82 is lifted, the supporting force between its bottom end and the contact block 84 and the ground is increased, so that the damping rod 82 can conduct the force to the ground more quickly when dissipating force, thereby improving the shock absorption efficiency of the device. When the first contact plate 74 and the second contact plate 79 are slightly offset due to vibration, the force dissipation rod 89 slides within the first contact plate 74, thereby reducing the longitudinal vibration force of the device and further improving the shock absorption efficiency.

The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by existing technologies.
