Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel construction equipment, specifically a misalignment adjustment device for a secondary lining trolley. Background Technology

[0002] Secondary lining trolleys, also known as tunnel lining trolleys, are specialized equipment essential for secondary lining in tunnel construction. They are used for constructing the concrete lining of the tunnel's inner walls. Concrete lining trolleys are indispensable non-standard products in secondary lining during tunnel construction, and mainly include simple lining trolleys, fully hydraulic automatic walking lining trolleys, and grid-type lining trolleys. Fully hydraulic lining trolleys can be further divided into side-top arch type, full-circular needle beam type, bottom-form needle beam type, and full-circular through-type, etc. In hydraulic tunnel and bridge construction, lifting slipform, jacking slipform, and flipping formwork are also commonly used.

[0003] Currently, during tunnel construction, the concrete lining of the tunnel wall needs to be constructed in multiple sections. After one section of the tunnel wall is completed, a track needs to be laid so that the secondary lining trolley can travel on the laid track and move along the next section of the tunnel wall that needs to be constructed. The accuracy of the track laying affects the accuracy of the connection between the secondary lining trolley and the previously constructed section of the tunnel wall.

[0004] Under current technological conditions, the complexity of the internal roadway of the tunnel poses a significant challenge to track laying. If errors occur in track laying and affect the docking of the secondary lining trolley, it will reduce the accuracy of the secondary lining trolley in tunnel laying, and thus cause deviations from the previously laid lining.

[0005] Therefore, this utility model provides a misalignment adjustment device for a secondary lining trolley. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A misalignment adjustment device for a secondary lining trolley, comprising two track bodies; multiple moving components are slidably connected to the middle of each track body; a support frame is fixedly connected to one side of each moving component; a fixing block is fixedly connected to the top of the support frame; hydraulic cylinders are fixedly connected to both sides of the fixing block; multiple longitudinal beams are provided on the outer side of the fixing block; buffer components are fixedly connected to one side of two of the longitudinal beams; the buffer components are fixedly connected to the hydraulic cylinders; and an anti-misalignment component is provided at the bottom of the other longitudinal beam; the anti-misalignment component is fixedly connected to the fixing block. During operation, the track bodies are laid out, the moving components are placed on the track bodies, and the hydraulic cylinders are adjusted so that the longitudinal beams fit against the tunnel inner wall. The moving components are activated, and the support frame moves along... The track body moves, and the longitudinal beams work in contact with the tunnel wall. When the longitudinal beams shift, hydraulic cylinders adjust and support them. Even if the track body misaligns, causing the support frame and fixing blocks to shift off-center from the tunnel center, the longitudinal beams can still maintain contact with the tunnel wall by adjusting the retraction distance of the two hydraulic cylinders. This allows for the adjustment of misalignment of the longitudinal beams on both sides. The longitudinal beams are in contact with each other, and the adjustment of the longitudinal beams on both sides will squeeze and drive the top longitudinal beam to move. With the help of anti-misalignment components, the top longitudinal beam fits more tightly with the two side longitudinal beams and follows the misalignment adjustment of the sides. By setting up segmented longitudinal beams, they fit with the tunnel wall, and hydraulic cylinders control the misalignment adjustment of the two side longitudinal beams. With the help of anti-misalignment components, the top longitudinal beam will also follow the adjustment.

[0008] Preferably, the buffer assembly includes a leaf spring fixedly connected to one side of the longitudinal beam. One side of the leaf spring is fixedly connected to a hydraulic cylinder, and the other side of the leaf spring is fixedly connected to multiple buffer cottons. The buffer cottons are in corresponding contact with the longitudinal beam. During operation, when a slight misalignment occurs, the leaf spring will deform under the supporting force of the hydraulic cylinder, making the leaf spring more conform to the shape of the longitudinal beam. The buffer cottons contact the longitudinal beam and buffer the leaf spring. Under the action of the leaf spring, a slight misalignment deviation occurs, and the misalignment adjustment can be completed without adjusting the hydraulic cylinder. By setting the leaf spring and buffer cotton, the misalignment adjustment control of the longitudinal beam can be more accurate and the control operation can be more convenient.

[0009] Preferably, the anti-misalignment component includes a cylinder fixedly connected to a fixed block, a sleeve fixedly connected to the top of the cylinder, a crossbar slidably connected to the middle of the sleeve, and the crossbar fixedly connected to the longitudinal beam. When working, the cylinder starts to support the sleeve, which in turn supports the top longitudinal beam. The crossbar is slidably connected to the sleeve. In this way, when the longitudinal beams on both sides are misaligned, the top longitudinal beam will be squeezed, and the sleeve will slide along the crossbar, achieving the effect of anti-misalignment self-adjustment.

[0010] Preferably, the sleeve is provided with baffles on both sides, and the baffles are fixedly connected to the crossbar. During operation, the baffles limit the range of movement of the crossbar, reducing the possibility of the top longitudinal beam excessively squeezing the longitudinal beams on both sides and causing them to overturn or misalign.

[0011] Preferably, a spring is fixedly connected to one side of the baffle, the spring is sleeved with the crossbar, and the other end of the spring is fixedly connected to the sleeve. During operation, the spring will link the baffle and the sleeve together, which can drive the crossbar to reset and reduce the situation where the sleeve and crossbar cannot spring back after being misaligned.

[0012] Preferably, the moving component is fixedly connected to two sides with blocks, which are correspondingly set with the track body. During operation, the blocks will block the two sides of the moving component and cooperate with the track body to reduce the entry of debris and impurities into the track body, thus preventing the track body and the moving component from jamming.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The misalignment adjustment device for a secondary lining trolley described in this utility model is achieved by setting segmented longitudinal beams that fit against the inner wall of the tunnel, and hydraulic cylinders controlling the misalignment adjustment of the longitudinal beams on both sides. With the help of anti-misalignment components, the top longitudinal beam is then driven to follow the adjustment.

[0015] 2. The misalignment adjustment device for a secondary lining trolley described in this utility model, by setting leaf springs and buffer cotton, enables more accurate control of the misalignment adjustment of the longitudinal beam and makes the operation more convenient.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 2 As shown in the embodiment of this utility model, a misalignment adjustment device for a secondary lining trolley includes two track bodies 1. Multiple moving components 11 are slidably connected to the middle of each track body 1. A support frame 12 is fixedly connected to one side of each moving component 11. A fixing block 13 is fixedly connected to the top of the support frame 12. Hydraulic cylinders 14 are fixedly connected to both sides of the fixing block 13. Multiple longitudinal beams 15 are provided on the outer side of the fixing block 13. Buffer components are fixedly connected to one side of two of the longitudinal beams 15, and the buffer components are fixedly connected to the hydraulic cylinders 14. An anti-misalignment component is provided at the bottom of the other longitudinal beam 15, and the anti-misalignment component is fixedly connected to the fixing block 13. During operation, the track body 1 is laid out, the moving component 11 is placed on the track body 1, and the hydraulic cylinders 14 are adjusted so that the longitudinal beam 15 fits against the tunnel inner wall. The moving component 11 is activated, and the support frame 12 moves along the track body 1. The longitudinal beam 15 operates in contact with the tunnel wall. When the longitudinal beam 15 shifts, the hydraulic cylinder 14 adjusts and supports it. Even if the track body 1 is misaligned, causing the support frame 12 and fixing block 13 to shift off-center from the tunnel center, the longitudinal beam 15 can still operate in contact with the tunnel wall by adjusting the retraction distance of the two hydraulic cylinders 14. This allows for the adjustment of the misalignment of the longitudinal beams 15 on both sides. The longitudinal beams 15 are in contact with each other. The adjustment of the longitudinal beams 15 on both sides will squeeze and drive the top longitudinal beam 15 to move. With the help of the anti-misalignment component, the top longitudinal beam 15 fits more tightly with the longitudinal beams 15 on both sides and follows the misalignment adjustment of the sides. By setting up segmented longitudinal beams 15, they fit with the tunnel wall. The hydraulic cylinder 14 controls the misalignment adjustment of the longitudinal beams 15 on both sides. With the help of the anti-misalignment component, the top longitudinal beam 15 is also adjusted accordingly.

[0025] like Figures 1 to 3 As shown, the buffer assembly includes a leaf spring 2 fixedly connected to one side of the longitudinal beam 15. One side of the leaf spring 2 is fixedly connected to the hydraulic cylinder 14, and the other side of the leaf spring 2 is fixedly connected to multiple buffer cotton 21s. The buffer cotton 21s are in corresponding contact with the longitudinal beam 15. During operation, when a slight misalignment occurs, the leaf spring 2 will deform under the supporting force of the hydraulic cylinder 14, making the leaf spring 2 more conform to the shape of the longitudinal beam 15. The buffer cotton 21s contact the longitudinal beam 15 and buffer the leaf spring 2. Under the action of the leaf spring 2, a slight misalignment deviation occurs, and the misalignment adjustment can be completed without adjusting the hydraulic cylinder 14. By setting the leaf spring 2 and the buffer cotton 21, the misalignment adjustment control of the longitudinal beam 15 can be more accurate and the control operation can be more convenient.

[0026] like Figures 1 to 4 As shown, the anti-misalignment component includes a cylinder 3 fixedly connected to a fixed block 13. A sleeve 31 is fixedly connected to the top of the cylinder 3, and a crossbar 32 is slidably connected to the middle of the sleeve 31. The crossbar 32 is fixedly connected to the longitudinal beam 15. When working, the cylinder 3 starts to support the sleeve 31, which in turn supports the top longitudinal beam 15. The crossbar 32 is slidably connected to the sleeve 31. When the two longitudinal beams 15 are misaligned, the top longitudinal beam 15 will be squeezed, and the sleeve 31 will slide along the crossbar 32 to achieve the anti-misalignment self-adjustment effect.

[0027] like Figures 1 to 4 As shown, the sleeve 31 is provided with baffles 4 on both sides. The baffles 4 are fixedly connected to the crossbar 32. During operation, the baffles 4 limit the movement range of the crossbar 32 to reduce the situation where the top longitudinal beam 15 excessively squeezes the side longitudinal beams 15 and causes them to overturn or misalign.

[0028] like Figures 1 to 4 As shown, a spring 5 is fixedly connected to one side of the baffle 4. The spring 5 is sleeved with the crossbar 32, and the other end of the spring 5 is fixedly connected to the sleeve 31. During operation, the spring 5 will link the baffle 4 and the sleeve 31 together, which can drive the crossbar 32 to reset and reduce the situation where the sleeve 31 and the crossbar 32 cannot spring back after being misaligned.

[0029] like Figures 1 to 5 As shown, the moving component 11 is fixedly connected to two sides of the stop block 6. The stop block 6 is correspondingly set with the track body 1. When working, the stop block 6 will block the two sides of the moving component 11 and cooperate with the track body 1 to reduce the entry of debris and impurities into the track body 1, so as to prevent the track body 1 and the moving component 11 from jamming.

[0030] Working principle: After the track body 1 is laid, the moving component 11 is placed on the track body 1. The hydraulic cylinder 14 is adjusted so that the longitudinal beam 15 fits against the inner wall of the tunnel. The moving component 11 is activated, and the support frame 12 moves along the track body 1. The longitudinal beam 15 fits against the inner wall of the tunnel. When the longitudinal beam 15 deviates, the hydraulic cylinder 14 adjusts and supports the longitudinal beam 15. Even if the track body 1 is misaligned, causing the support frame 12 and the fixing block 13 to deviate from the center of the tunnel, the longitudinal beam 15 can still fit against the inner wall of the tunnel by adjusting the retraction distance of the two hydraulic cylinders 14. The wall-mounted structure allows for the adjustment of the misalignment of the two longitudinal beams 15. The longitudinal beams 15 are in contact with each other; the adjustment of the two longitudinal beams 15 compresses and moves the top longitudinal beam 15. Combined with the anti-misalignment component, this ensures a tighter fit between the top and two longitudinal beams 15, allowing it to follow the misalignment adjustment. By using segmented longitudinal beams 15 that fit against the tunnel wall, the hydraulic cylinder 14 controls the misalignment adjustment of the two longitudinal beams 15. With the anti-misalignment component, this further drives the top longitudinal beam 15 to adjust accordingly. When a slight misalignment occurs, the leaf spring 2 is activated by the hydraulic cylinder 14. The supporting force causes deformation, making the leaf spring 2 fit the shape of the longitudinal beam 15 more closely. The cushioning cotton 21 contacts the longitudinal beam 15, cushioning the leaf spring 2. Under the action of the leaf spring 2, a slight misalignment occurs, which can be adjusted without adjusting the hydraulic cylinder 14. By setting the leaf spring 2 and the cushioning cotton 21, the misalignment adjustment control of the longitudinal beam 15 can be more accurate and the operation more convenient. The start of the cylinder 3 will support the sleeve 31, thereby supporting the top longitudinal beam 15. The crossbar 32 is slidably connected to the sleeve 31. When the two longitudinal beams 15 are misaligned, the top one will be squeezed. The longitudinal beam 15, and then the sleeve 31 slides along the crossbar 32 to achieve the effect of anti-misalignment self-adjustment. The baffle 4 limits the range of movement of the crossbar 32 to reduce the situation where the top longitudinal beam 15 excessively squeezes the two side longitudinal beams 15 and causes them to overturn and misalign. The spring 5 will link the baffle 4 and the sleeve 31 together, which can drive the crossbar 32 to reset and reduce the situation where the sleeve 31 and the crossbar 32 cannot rebound after misalignment adjustment. The stop block 6 will block the two sides of the moving component 11 and cooperate with the track body 1 to reduce the entry of debris and impurities into the track body 1, which would cause the track body 1 and the moving component 11 to jam.
