It mainly has the following functions: supporting the surrounding rock, waterproofing and moisture-proofing, and providing a flat surface. Tunnel lining is usually constructed with materials such as concrete or reinforced concrete. Its construction process generally includes the following steps: initial support, lining trolley placement, formwork installation, concrete pouring, curing and demolding.

[0003] The tunnel secondary lining trolley is a large mechanical equipment used for tunnel secondary lining construction. It mainly consists of: walking mechanism, template system, support mechanism, adjustment mechanism, hydraulic system and electrical control system. The benefits and functions of the tunnel secondary lining trolley include: improving construction efficiency, ensuring construction quality, enhancing construction safety and adapting to different tunnel conditions.

[0004] The current new type of tunnel secondary lining trolley still has the following shortcomings:

[0005] 1.

At the same time, there are safety risks in the installation of air ducts, and the ventilation effect is poor;

[0006] 2. The current lighting system of the tunnel secondary lining trolley is fixed in position, and it is difficult to change the position up, down, left, and right according to actual conditions. The sealing opening is often sealed with fixed steel plates, which are relatively complicated to install and prone to deformation after long-term use, resulting in reduced compactness in subsequent work.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it 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 a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] See also Figures 1 to 7The present invention provides a technical solution: a new type of tunnel secondary lining trolley, comprising a walking mechanism 1, the top of the walking mechanism 1 is screwed to the two ends of the bottom of the bottom plate 2, the two ends of the top of the bottom plate 2 are provided with a supporting main frame 3, a first slide groove 4 is opened in the middle of the top of the supporting main frame 3, the inner walls on both sides of the first slide groove 4 are rotatably connected with a moving mechanism 5, an adjusting mechanism 6 is screwed on the top of the moving mechanism 5, and a lighting lamp 7 is installed in the middle of the top of the adjusting mechanism 6, supporting side plates 8 are provided at the two ends of the opposite sides of the supporting main frames 3 on both sides, and fixing plates 9 are provided at the tops of the opposite sides of the supporting main frames 3 on both sides, and a plurality of hydraulic push rods 10 are screwed on one end of the outer side of the supporting side plates 8 and the fixing plates 9, and the driving ends of the plurality of hydraulic push rods 10 are inserted into one side of the inner wall of the template 11, a supporting mechanism 12 is screwed in the middle of the bottom of the bottom plate 2, and a ventilation pipe 13 is horizontally penetrated inside the supporting main frames 3 on both sides.

[0036] In this embodiment, Figure 1 and Figure 6 As shown, the walking mechanism 1 includes a hydraulic cylinder 101, a U-shaped frame 102, a rotating shaft 103, a connecting plate 104 and a roller 105. The top of the hydraulic cylinder 101 is screwed to the two ends of the bottom of the base plate 2, and the driving end of the hydraulic cylinder 101 is plugged into the top of the connecting plate 104. The middle part of the bottom of the connecting plate 104 is provided with a U-shaped frame 102, and the opposite side of the U-shaped frame 102 is rotatably connected with the rotating shaft 103, and the outer wall of the rotating shaft 103 is sleeved with the roller 105; it should be noted that when the trolley needs to move, the driving end of the hydraulic cylinder 101 extends and drives the connecting plate 104 and the U-shaped frame 102 connected thereto to descend together until the roller 105 contacts the ground. At this time, the roller 105 can roll on the ground in the tunnel through the rotating shaft 103 plugged therein to drive the trolley to move, and when the trolley After reaching the construction position, the driving end of the hydraulic cylinder 101 retracts, and drives the connecting plate 104 and the U-shaped frame 102 to move upward, thereby causing the roller 105 to break contact with the ground, and at the same time starting the support mechanism 12 to support the weight of the entire trolley to ensure the stability of the construction process. In actual use, the hydraulic cylinder 101 in the walking mechanism 1 drives the roller 105 to descend and contact the ground, so that the trolley can be easily moved in the tunnel, so that it can quickly reach the designated position according to construction requirements. When it reaches the construction position, its roller 105 can roll on the tunnel floor, which can better adapt to various terrain conditions in the tunnel and reduce the impact of factors such as terrain undulations on the movement of the trolley. At the same time, the drive control of the hydraulic cylinder 101 is relatively simple, which is convenient for the operator to accurately control the movement and positioning of the trolley and improve construction efficiency.

[0037] In this embodiment, Figure 6As shown, a camera is clamped on one side of the top of the connecting plate 104, and a level is screwed on the other side. It should be noted that when the operator uses the hydraulic cylinder 101 to push the roller 105 downward to make it contact with the ground, the camera clamped on one side of the top of the connecting plate 104 will monitor the contact between the roller 105 and the ground in real time, and feed back the monitoring image to the computer set in the front of the vehicle in real time and display it. At the same time, the level screwed on the other side of the top of the connecting plate 104 is started to emit horizontal rays. At this time, the camera displays the operating images of the level in four directions through the computer in real time, which is convenient for the operator to observe whether the four level gauges are balanced, so as to adjust the balance. The telescopic length of the hydraulic cylinder 101 is actually monitored by a camera in real time to see the contact between the roller 105 and the ground, so that the operator can intuitively see the lifting and lowering status of the roller 105, thereby ensuring that it is in correct contact with the ground and avoiding problems such as poor contact that affect the movement of the trolley. The real-time image feedback from the camera can provide the operator with accurate information so that the lifting and lowering process of the roller 105 can be adjusted in time through the hydraulic cylinder 101. The level meter cooperates with the camera to allow the operator to observe the horizontal state of the roller 105 in four directions, so that it can be discovered in time whether the trolley is in a balanced state and make real-time adjustments, which can effectively avoid construction errors and quality problems caused by the tilt of the trolley.

[0038] In this embodiment, Figure 2 and Figure 4 As shown, two tripods 301 are provided on the inner walls of the opposite sides of the supporting main frame 3, and the inner walls of the tripods 301 are provided with clamping rings 302, and the inner walls of the clamping rings 302 are clamped with ventilation pipes 13; it should be noted that the operator can first insert the ventilation pipe 13 from one end of the inner wall of the tripod 301 on one side, and make the two side ends of the ventilation pipe 13 respectively clamped into the clamping rings 302 on both sides to ensure that the ventilation pipe 13 is firmly fixed, and then connect one end of the ventilation pipe 13 to the air intake system of the tunnel, and the other end to the exhaust system of the tunnel, so that fresh air can be ventilated. The ventilation pipe 13 is transported to the construction area near the trolley. In actual use, the tripod 301 and the clamp ring 302 provide a supporting structure for the ventilation pipe 13, thereby enhancing the overall stability and reliability of the ventilation pipe 13. The shape setting of the tripod 301 is conducive to the rational use of the internal space of the supporting main frame 3, making the installation of the ventilation pipe 13 more compact and orderly, thereby reducing the installation risk of the ventilation pipe 13, and the clamp ring 302 can firmly engage the ventilation pipe 13 to prevent the ventilation pipe 13 from shaking or shifting during use, while ensuring the stability of the ventilation effect.

[0039] In this embodiment, Figure 4As shown, the moving mechanism 5 includes a multi-directional screw 501, a moving screw seat 502 and a driving motor 503. The left and right ends of the multi-directional screw 501 are rotatably connected to the inner walls of both sides of the first slide groove 4. The outer wall of the multi-directional screw 501 is screwed with a plurality of groups of moving screw seats 502. One end of the multi-directional screw 501 is plugged with a driving motor 503. It should be noted that when the trolley is moved to the construction site through the walking mechanism 1 and the trolley is supported and fixed by the supporting mechanism 12, its operator can start the driving motor 503 according to the actual situation, so that it drives the multi-directional screw 501 plugged therein to start rotating, so that the multiple groups of moving screws screwed on the outer wall of the multi-directional screw 501 are screwed. The screw seat 502 and the water move closer to or farther away from each other along the direction of their respective threads, thereby causing the adjustment mechanism 6 and the lighting lamp 7 installed inside the movable screw seat 502 to move synchronously, thereby realizing the horizontal position change of the lighting lamp 7. In actual use, the setting of the movable mechanism 5 can conveniently adjust the horizontal position of the lighting lamp 7 according to the specific needs of the construction, thereby ensuring that the construction area can obtain sufficient and appropriate lighting, improving the visibility and accuracy of the construction, and the setting of the movable mechanism 5 can quickly and conveniently realize the change of the horizontal position of the lighting lamp 7, thereby saving the time of construction pauses or repeated operations that may be caused by poor lighting, and improving the overall construction efficiency.

[0040] In this embodiment, Figure 4 and Figure 5As shown, the adjustment mechanism 6 includes an electric push rod A601, a bottom frame 602, a rotating T-block 603, a rotating rod 604 and an electric telescopic rod 605. The bottom end of the electric push rod A601 is screwed to the inside of the movable screw seat 502. The driving end of the electric push rod A601 is provided with a bottom frame 602. The opposite side of the bottom frame 602 is rotatably connected with a rotating rod 604. The outer wall of the rotating rod 604 is sleeved with a rotating T-block 603. Electric telescopic rods 605 are provided between the two sides of the bottom of the rotating T-block 603 and the left and right outer walls of the bottom frame 602. The outside of the lighting lamp 7 is provided with The protective cover 701 has a reflective coating on its surface. It should be noted that after the operator completes the horizontal position change of the lighting lamp 7 through the moving mechanism 5, the operator can simultaneously start multiple electric push rods A601 through an external controller, so that the driving end drives the various components and the lighting lamp 7 located directly above it to perform lifting operations. After the lighting lamp 7 is adjusted to a suitable height, the operator can simultaneously start the electric telescopic rods 605 located on the left and right sides of the bottom frame 602, so that the two electric telescopic rods 605 are extended one by one. One is shortened, and drives the two sides of the rotating T block 603 connected to each other to rotate, thereby forming a tilted state, so that the lighting lamp 7 set on the top of the rotating T block 603 can change the illumination angle, so that its light passes through the protective cover 701 to irradiate the outside. In actual use, by starting the adjustment mechanism 6, the height of the lighting lamp 7 can be easily adjusted to adapt to the requirements of the illumination height in different construction scenes to ensure the best lighting effect. The cooperation of the electric telescopic rod 605 and the rotating T block 603 can enable the lighting lamp 7 to change the illumination angle, thereby providing a more accurate illumination direction and better meeting the lighting requirements of construction personnel for specific areas. At the same time, the adjustment mechanism 6 can flexibly fine-tune the angle of the lighting lamp 7 according to the actual construction situation, thereby improving the adaptability and practicality of the trolley in different construction environments and tasks. The protective cover 701 with a reflective coating is set on the outside of the lighting lamp 7, which can not only enhance the lighting brightness, protect the lamp, and extend the life, but also improve the construction safety, adapt to different environments and reduce maintenance costs. This design has important practical application value in scenes such as tunnel construction, mine operations and equipment maintenance.

[0041] In this embodiment, Figure 3As shown, a reserved opening 1101 is provided on the surface of the template 11; it should be noted that when the operator pushes the connected templates 11 outwards through a plurality of hydraulic push rods 10, the templates 11 at each location can form the lining shape of the tunnel, and then the concrete delivery pipeline is connected to the reserved opening 1101, and concrete is injected into the gap between the template 11 and the tunnel through the reserved opening 1101. When the concrete enters from the reserved opening 1101, it will gradually fill various parts to ensure the integrity of the lining. After the concrete pouring is completed, the reserved opening 1101 is sealed with a blocking plate 1103. 101 is sealed to avoid concrete leakage. In actual use, the setting of the reserved opening 1101 provides a channel for the injection of concrete, so that the concrete can smoothly enter the gap between the template 11 and the tunnel, ensuring the formation of the lining, and the concrete can evenly fill various parts after entering from the reserved opening 1101, which helps to ensure the integrity and quality of the lining. At the same time, the existence of the reserved opening 1101 makes the transportation and pouring of concrete more convenient, improves the construction efficiency, and in different construction stages, the reserved opening 1101 can be used for concrete pouring as needed.

In actual use, the second slide groove 1102, the blocking plate 1103, the electric push rod B1104 and the slide bar 1105 are set together to achieve the functions of sealing and convenient operation. The second slide groove 1102 provides a track for the movement of the blocking plate 1103, ensuring the stability and accuracy of the movement of the blocking plate 1103. At the same time, the electric push rod B1104, as a driving device, can accurately control the movement of the blocking plate 1103 to achieve fast and convenient blocking operations. The slide bar 1105 cooperates with the second slide groove 1102 to further enhance the smoothness and sealing of the movement of the blocking plate 1103.

[0045] like Figures 1 to 7As shown, first, the operator can start the hydraulic cylinder 101 to extend its driving end and drive the connecting plate 104 and the U-shaped frame 102 connected thereto downward to descend together until the roller 105 contacts the ground. At the same time, the camera connected to one side of the top of the connecting plate 104 will monitor the contact between the roller 105 and the ground in real time, and feed back the monitoring image to the computer set at the front of the vehicle for display in real time. At the same time, the level meter screwed to the other side of the top of the connecting plate 104 is started to emit a horizontal ray. At this time, the camera displays the running images of the level meters in four directions in real time through the computer, which is convenient for the operator to observe whether the four level meters are balanced, and adjust the extension length of the hydraulic cylinder 101 to adjust the rollers 105 in four directions to the ground. The ground remains flat, and the roller 105 can roll on the ground in the tunnel through the rotating shaft 103 connected thereto, driving the trolley to move. When the trolley reaches the construction position, at the same time, its operator can first start the small hydraulic press 1201, so that its driving end begins to extend obliquely downward, and pushes the large hydraulic press 1202 connected thereto to move downward. At the same time, the connecting rotating block 1204 arranged at the tail end of the large hydraulic press 1202 will rotate in contact with the fixed block 1205 through the rotating column 1206 inserted into its inner wall. During this period, the sleeve block 1207 sleeved on the middle section of the large hydraulic press 1202 will be lowered together, and at the same time, the connecting rod 1208 and the stop block B1209 connected thereto will be pushed obliquely downward to be close to the ground. , until the bottom end of the block B1209 can fit tightly against the ground, and then the operator can start the large hydraulic press 1202 to make its driving end extend obliquely and push the block A1203 connected thereto toward the ground, until the bottom end of the block A1203 can fit tightly against the ground, and form a triangular structure with the connecting rod 1208 and the block B1209, thereby completing the support and fixation of the trolley, and then the operator can start the driving motor 503 according to the actual situation, so that it drives the multi-directional screw 501 connected thereto to start rotating, so that the multiple sets of mobile screw seats 502 screwed to the outer wall of the multi-directional screw 501, the water approaches or moves away from each other along the direction of their respective threads, thereby bringing along the adjustment mechanism installed inside the mobile screw seat 502. 6 and the lighting lamp 7 move synchronously, thereby realizing the position change of the lighting lamp 7 in the lateral position, and simultaneously starting multiple electric push rods A601, so that the driving end thereof drives the various components arranged directly above it and the lighting lamp 7 to perform lifting operations. After the lighting lamp 7 is adjusted to a suitable height, its operator can simultaneously start the electric telescopic rods 605 arranged on the left and right sides of the bottom frame 602, so that the two electric telescopic rods 605 are extended and shortened respectively, and drive the two sides of the rotating T block 603 connected to them to rotate, thereby forming a tilted state, so that the lighting lamp 7 arranged on the top of the rotating T block 603 can change the illumination angle. After that, the operator can start multiple hydraulic push rods 10 to push the templates 11 connected to them to the outside.The templates 11 at various locations can form the lining shape of the tunnel, and then the concrete delivery pipe is connected to the reserved opening 1101, and the concrete is injected into the gap between the template 11 and the tunnel through the reserved opening 1101. When the concrete enters from the reserved opening 1101, it will gradually fill various parts to ensure the integrity of the lining. When the concrete pouring is completed, the operator can start the electric push rod B1104 through the external controller to make its driving end begin to extend horizontally and push the blocking plate 1103 connected to it to move horizontally. During this period, the sliding bar 1105 provided on the side of the blocking plate 1103 close to the inner wall of the template 11 will slide horizontally against the inner wall of the second slide groove 1102 until the reserved opening 1101 is blocked, which is convenient for subsequent construction and vibration operations.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
