Description

Technical Field

[0001] The present invention relates to the technical field of tunnel maintenance, and in particular to an intelligent tunnel lining maintenance trolley. Background Art

[0002] Tunnel lining maintenance trolleys are specialized equipment used for maintaining moisture and heat preservation after secondary concrete lining during tunnel construction. They are particularly crucial in harsh environments such as high altitude and plateau conditions. Currently, the main body of the maintenance trolley consists of a steel arch frame and supporting beams. During the maintenance process, the secondary concrete lining needs to be tapped to detect concrete hollows, so as to facilitate rapid maintenance and re-pouring. After pouring the concrete, the formwork needs to be vibrated to ensure the compactness of the concrete. However, the maintenance trolley with a steel structure is very likely to cause metal fatigue damage or steel component falling off due to the vibration of the long-term vibrating device, which affects the service life of the maintenance trolley. In addition, during the current maintenance process, atomization or water spraying is used to maintain the humidity of the surface of the secondary concrete lining. Due to the arched setting of the tunnel, the water will flow downward from the middle along the tunnel, resulting in inconsistent humidity of the surface concrete, affecting the actual concrete solidification effect, and the downward flowing water will also cause water accumulation in the tunnel, which is not easy to clean in high-altitude and cold areas. Based on this, an intelligent tunnel lining maintenance trolley is proposed. Summary of the Invention

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0022] Example, refer to Figures 1 to 8, an intelligent tunnel lining maintenance trolley, including a maintenance platform, the maintenance platform consists of an upper support frame 1 and a mobile support column 2 arranged at the bottom of the support frame 1, wherein the bottom of the mobile support column 2 is provided with a locking universal wheel for facilitating the transfer of the maintenance platform, and the mobile support column 2 is connected to the support frame 1 through a reinforcement frame. The maintenance platform is provided with a maintenance unit for maintaining the tunnel lining and a maintenance unit for maintaining the tunnel lining; The maintenance unit includes two trolley guard plates 3 arranged opposite to each other in an arc shape above the maintenance platform. A winding and lifting device is provided in the middle position of the trolley guard plates 3. Furthermore, the winding and lifting device includes a winding motor 14 arranged on the trolley guard plates 3. The winding motor 14 is a prior art and will not be described in detail here. The output end of the winding motor 14 is connected to a winding wheel 15, and a traction rope is wound around the winding wheel 15 for winding.

[0023] The trolley guard plate 3 is connected to the liquid replenishing bracket 4 through a traction moving part. Furthermore, the traction moving part includes an arc-shaped guide rail 16 provided on the trolley guard plate 3. An arc-shaped guide groove 17 is provided on the arc-shaped guide rail 16. The middle of the arc-shaped guide groove 17 is farther away from the tunnel concrete surface, and the two sides are closer to the tunnel concrete surface. Such an arrangement can achieve that as the liquid replenishing bracket 4 moves to the sides, the inner diameter of the arc-shaped guide groove 17 continues to increase, which will increase the contact pressure between the liquid replenishing layer 6 and the tunnel concrete surface, thereby compensating for the lack of water in the later stage, so as to ensure a consistent wetting effect on the concrete tunnel surface; Both ends of the fluid infusion bracket 4 are rotatably connected to a slide rail sleeve 18. The rotatable connection setting can ensure that the fluid infusion bracket 4 is always facing upward when moving on the arc guide rail 16 under the action of its own gravity, thereby achieving the effect of storing the liquid. The slide rail sleeve 18 is connected to the arc guide groove 17 through a notch, and the slide rail sleeve 18 is fixedly connected to one end of the traction rope through a traction ring.

[0024] A plurality of force-storage knocking detection members are provided on one side of the infusion bracket 4; further, the force-storage knocking detection member includes a fixed force-storage seat 19 provided on the side wall of the infusion bracket 4, and the fixed force-storage seat 19 is connected to a toggle rod 20 through a force-storage torsion spring shaft. A torsion spring is provided in the force-storage torsion spring shaft. When the toggle rod 20 is blocked by a blocking prism 23, it will achieve a force storage effect when it rotates. An elastic metal paddle 21 is provided at the end of the toggle rod 20, and a knocking ball 22 is provided on the elastic metal paddle 21. A plurality of blocking prisms 23 for blocking the movement of the toggle rod 20 are evenly provided on the two trolley guard plates 3; The advantage of adopting the above structure is that during the upward movement of the liquid replenishing bracket 4 from both sides, the toggle rod 20 on its side wall will be blocked when it moves to the blocking prism 23 and gradually rotates to store energy. When the elastic metal flap 21 provided at the end of the toggle rod 20 disengages from the blocking prism 23 during the movement, it will quickly rebound under the action of the torsion spring, so that the provided knocking ball 22 knocks on the tunnel concrete surface to realize the inspection of the hollowing of the concrete surface.

[0025] A liquid replenishing roller 5 is rotatably arranged in the liquid replenishing bracket 4, a liquid replenishing layer 6 is arranged on the outer surface of the liquid replenishing roller 5, and a feeding and replenishing assembly for replenishing the liquid in the liquid replenishing bracket 4 is arranged on the trolley guard plate 3; Among them, the traction rope wound on the winding wheel 15 is gradually released. Under the action of gravity, the liquid replenishing brackets 4 on the two side arc-shaped guide rails 16 will gradually move downward. When moving downward, since the liquid replenishing layer 6 on the liquid replenishing roller 5 is in a state of being squeezed against the tunnel inner wall, the liquid replenishing roller 5 will rotate closely against the tunnel inner wall during the movement of the liquid replenishing bracket 4 to both sides. It can absorb the liquid in the liquid replenishing bracket 4 and achieve the effect of wetting the concrete surface when contacting the concrete surface.

[0026] Furthermore, the feeding and replenishing assembly includes a supporting feeding and replenishing pipe 24 arranged at the topmost part of the trolley guard plate 3. The supporting feeding and replenishing pipe 24 is connected with a liquid replenishing pump through a conveying pipe. A liquid storage tank is arranged on the maintenance bench frame, which is an existing way to replenish liquid and is prior art, so no detailed description will be given here.

[0027] The maintenance unit includes a maintenance seat 7 connected to the maintenance bench frame through a slide rail moving part. Furthermore, the slide rail moving part includes a U-shaped guide rail 25 fixedly arranged on the inner wall of the maintenance bench frame. The bottom of the maintenance seat 7 is fixedly connected with a sliding support plate 26 with both ends located in the U-shaped guide rail 25. The use of the slide rail moving part can meet the flexible movement between the maintenance unit and the maintenance bench frame.

[0028] The maintenance seat 7 is connected with a maintenance vertical arm 8 through a height adaptation adjustment part. Furthermore, the height adaptation adjustment part includes an adjustment motor 27 arranged in the maintenance seat 7. The output end of the adjustment motor 27 is connected with an adjustment lead screw 28. The adjustment lead screw 28 is threadedly connected with an adjustment slider 29. The outer side wall of the maintenance vertical arm 8 is fixedly connected with an adjustment support plate 30. The adjustment support plate 30 is rotatably connected with the adjustment slider 29 through two adjustment support rods 31. Both ends of the adjustment support rod 31 are rotatably connected with the adjustment slider 29 and the adjustment support plate 30 respectively. By controlling the adjustment lead screw 28 to rotate through the adjustment motor 27, the adjustment slider 29 can be driven to move, so that the adjustment support plate 30 supported by the adjustment support rod 31 drives the maintenance vertical arm 8 to move upward, achieving the effect of flexible adjustment according to the height of the maintenance area.

[0029] A turntable 9 is provided on the top of the maintenance arm 8, and the turntable 9 is connected to the arc-shaped support template 11 through a universal connector 10. Arc-shaped adjustment parts for adjusting the angle of the arc-shaped support template 11 are provided on both sides of the turntable 9. The arc-shaped adjustment parts include adjustment arms 32 provided on the side walls of the turntable 9, and adjustment nuts are fixedly provided on the adjustment arms 32. The adjustment nuts are threadedly connected to adjustment studs 33, and a resistance ball is provided on the top of the adjustment studs 33. According to the curvature of the repair area, the adjustment studs 33 on the adjustment arms 32 on both sides are adjusted to change the height of the adjustment studs 33 on both sides, so that the support angle of the arc-shaped support template connected by the universal connector 10 changes to meet the support effect of different areas.

[0030] The outer wall of the maintenance arm 8 is connected to a vibrating device 13 through an airbag shock-absorbing collar 12, and is connected to the maintenance arm 8 through the airbag shock-absorbing collar 12 to prevent the vibrating device 13 from causing adverse effects on the maintenance trolley. Stud assembly tubes 34 are provided on both sides of the airbag shock-absorbing collar 12. The stud assembly tubes 34 are connected to the vibrating device 13 and are used to independently support the vibrating device 13. The stud assembly tubes 34 are threadedly connected with detachable studs 35. The vibrating device 13 is provided on both sides of the airbag shock-absorbing collar 12 and is used to vibrate the arc-shaped support formwork 11.

[0031] The present invention gradually maintains the tunnel lining by intermittently moving the maintenance platform during the maintenance of the tunnel lining. During this process, the tunnel lining is maintained when the maintenance platform is in a stationary state. During the maintenance process, the hollowing of the tunnel lining concrete is simultaneously checked. Specifically, Under the action of the supporting feeding pipe 24, the replenishing liquid is transported to the replenishing bracket 4. At this time, the winding motor 14 is controlled to reverse, and the traction rope originally wound on the winding wheel 15 is gradually released. Under the action of gravity, the replenishing bracket 4 on the arc guide rails 16 on both sides will gradually move downward. When moving downward, since the replenishing layer 6 on the replenishing drum 5 is in a squeezed state with the inner wall of the tunnel, the replenishing drum 5 will rotate closely against the inner wall of the tunnel during the movement of the replenishing bracket 4 to both sides. During the rotation, the liquid in the replenishing bracket 4 is continuously transferred to the concrete secondary lining surface, and as it moves to both sides, the inner diameter of the arc guide groove 17 continues to increase, which will increase the contact pressure between the replenishing layer 6 and the tunnel concrete surface, thereby compensating for the lack of water in the later stage, so as to ensure the consistent wetting effect on the concrete tunnel surface, and the infiltration method can effectively avoid the situation where the liquid flows downward and causes water accumulation in the tunnel; After completing the downward infiltration movement, the take-up motor 14 is driven to rotate forward to wind the towing rope, driving the liquid supplement support bracket 4 to move upward. During this process, the toggle lever 20 rotatably arranged on the side wall of the liquid supplement support bracket 4 will be blocked by the blocking prism 23 arranged on the trolley guard plate 3 during the movement, gradually rotating and storing energy. When the elastic metal flap 21 arranged at the end of the toggle lever 20 disengages from the blocking prism 23 during the movement, it will quickly rebound under the action of the torsion spring, so that the arranged knocking ball 22 knocks on the tunnel concrete surface. Maintenance personnel can distinguish whether there is a hollow sound on the tunnel concrete surface through the inconsistent sound, so as to achieve the effect of detecting the tunnel concrete surface during the maintenance process; When detecting the hollow sound on the concrete surface, repair the concrete at the hollow part. Break and clean the original concrete. Move the arc-shaped support formwork 11 on the maintenance vertical arm 8 by moving the maintenance vertical arm 8 arranged on the maintenance platform frame, and repair the concrete in this area. According to the radian of the repair area, adjust the adjusting studs 33 on the adjusting arms 32 on both sides to change the height of the adjusting studs 33 on both sides, so that the arc-shaped support formwork 11 connected by the universal joint 10 changes the support angle to meet the support effect of different areas. After the concrete is poured, rotate the detachable stud 35 to combine with the stud assembly cylinder 34 to achieve the independent support of the vibrating device 13. And the way that its supporting structure is connected to the maintenance vertical arm 8 through the airbag shock-absorbing collar 12 can avoid the serious impact of the vibrating device 13 on the maintenance trolley.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
