[0002] Tunnel lining is a permanent structure used to support and maintain the long-term stability and durability of tunnels. To improve the reliability of tunnel lining, manual water spraying is usually carried out on its surface after the tunnel lining construction is completed.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-6 As shown, this embodiment provides a tunnel lining maintenance trolley, including a trolley body 1 and a spacing adjustment assembly 2. The trolley body 1 includes a first frame structure 11, a second frame structure 12, and a water supply assembly 13 arranged at intervals. Both the first frame structure 11 and the second frame structure 12 are provided with multiple nozzles 14 spaced apart and facing the tunnel lining. The water supply assembly 13 supplies water to the multiple nozzles 14, enabling the multiple nozzles 14 to perform water spraying maintenance on the tunnel lining. The first frame structure 11 has a first chute 111 extending along a first horizontal direction, and the second frame structure 12 has a second chute 121 extending along the first horizontal direction. The spacing adjustment assembly 2 includes a first adjusting member 21 and a second adjusting member 22. The component 22 and the connector 23 are configured such that the first adjusting member 21 is movably disposed in the first slide groove 111 and the second adjusting member 22 is movably disposed in the second slide groove 121. The first adjusting member 21 and / or the second adjusting member 22 can move along the first horizontal direction to adjust the distance between the first frame structure 11 and the second frame structure 12 in the first horizontal direction. The first end of the connector 23 is rotatably connected to the first adjusting member 21 along its own length direction, and the second end is rotatably connected to the second adjusting member 22. The first end and the second end of the connector 23 can rotate relative to each other to adjust the distance between the first frame structure 11 and the second frame structure 12 in the second horizontal direction. The second horizontal direction is set at an angle to the first horizontal direction. Specifically, the first adjusting member 21 has a first mounting groove, the first rotating shaft 212 is disposed in the first mounting groove, the first end of the connecting member 23 is rotatably connected to the first rotating shaft 212, the second adjusting member 22 has a second mounting groove, the second rotating shaft 222 is disposed in the second mounting groove, and the second end of the connecting member 23 is rotatably connected to the second rotating shaft 222. In this embodiment, the rotation of the first end of the first adjusting member 21 and the connecting member 23 is achieved by means of the first rotating shaft 212, and the rotation of the second end of the second adjusting member 22 and the connecting member 23 is achieved by means of the second rotating shaft 222.

[0032] In this embodiment, the first adjusting member 21 is movably disposed within the first sliding groove 111 opened along the first horizontal direction in the first frame structure 11, and the second adjusting member 22 is movably disposed within the second sliding groove 121 opened along the first horizontal direction in the second frame structure 12. Both the first adjusting member 21 and the second adjusting member 22 are rotatably connected to the connecting member 23. Movement of at least one of the first adjusting member 21 and the second adjusting member 22 along the first horizontal direction adjusts the distance between the first frame structure 11 and the second frame structure 12 in the first horizontal direction. When the first end and the second end of the connecting member 23 rotate relative to each other, the angle between the first adjusting member 21 and the second adjusting member 22 in the second horizontal direction, which forms an angle with the first horizontal direction, also changes. This achieves the effect of adjusting the distance between the first frame structure 11 and the second frame structure 12 in the second horizontal direction. The distance adjustment component 2 enables the installation flexibility of the first frame structure 11 and the second frame structure 12 at tunnel linings of different sizes. Both the first frame structure 11 and the second frame structure 12 are provided with multiple nozzles 14 that face the tunnel lining at intervals. With the help of the water supply function of the water supply component 13 and the spacing adjustment effect of the spacing adjustment component 2 on the first frame structure 11 and the second frame structure 12, the tunnel lining maintenance trolley proposed in this embodiment can achieve universality for the maintenance of tunnel linings of different sizes. Moreover, the water supply component 13 and the nozzles 14 realize automatic water spraying maintenance of the tunnel lining, which improves the continuity and efficiency of the maintenance operation, avoids the structural strength difference caused by the difference in maintenance time in different areas of the tunnel lining, and ensures the overall maintenance quality and structural strength of the tunnel lining.

[0033] It is understood that in this embodiment, the movement of the first adjusting member 21 can be achieved either by manually pushing the first frame structure 11 along the first horizontal direction, or by setting a linear drive mechanism at the first frame structure 11 and using the driving effect of the linear drive mechanism on the first frame structure 11 along the first horizontal direction; the movement of the second adjusting member 22 along the second horizontal direction can also be achieved either by manual driving, or by using the driving effect of the linear drive mechanism on the second frame structure 12; the relative rotation process of the first end and the second end of the connecting member 23 can be achieved either by manually pushing at least one of the first frame structure 11 and the second frame structure 12 along the second horizontal direction, or by setting a rotary drive mechanism at at least one of the first frame structure 11 and the second frame structure 12 and using the rotational driving effect of the rotary drive mechanism, and no specific limitation is made here.

[0034] In this embodiment, the movement of the first adjusting member 21 and the second adjusting member 22 along the first horizontal direction, as well as the relative rotation between the first and second ends of the connecting member 23, are all achieved manually. To improve operational convenience, the bottom of both the first frame structure 11 and the second frame structure 12 are rotatably equipped with lockable casters. The casters improve the mobility of the first frame structure 11 and the second frame structure 12 and reduce the intensity of manual operation. The locking effect of the casters improves the positioning accuracy of the first frame structure 11 and the second frame structure 12 after they are pushed into place, ensuring the quality of tunnel lining maintenance and avoiding omissions or uneven maintenance of the tunnel lining due to positional deviations of the trolley body 1.

[0035] For example, the relative rotation process of the first end and the second end of the connector 23 can be performed first, that is, the connector 23 can be pushed along the second horizontal direction to realize the spacing adjustment process of the first frame structure 11 and the second frame structure 12 in the second horizontal direction. Then, at least one of the first frame structure 11 and the second frame structure 12 can be pushed along the first horizontal direction to realize the relative movement of the first adjusting member 21 and the second adjusting member 22 in the first horizontal direction, thereby adjusting the spacing of the first frame structure 11 and the second frame structure 12 in the first horizontal direction.

[0036] In some embodiments, such as Figure 1 and Figure 2 As shown, the first adjusting member 21 is slidably disposed in the first sliding groove 111, and the second adjusting member 22 is slidably disposed in the second sliding groove 121. The sliding stability of the first adjusting member 21 and the second adjusting member 22 along the first horizontal direction is strong, which improves the spacing adjustment accuracy of the first frame structure 11 and the second frame structure 12 in the first horizontal direction.

[0037] Specifically, to reduce the material cost and processing precision requirements of the trolley body 1, the first groove 111 and the second groove 121 can be grooves extending along the first horizontal direction and penetrating along the second horizontal direction, such as... Figure 3 and Figure 4As shown, a first limiting groove 112 is provided on the groove wall of the first sliding groove 111, and a second limiting groove 122 is provided on the groove wall of the second sliding groove 121. Both the first limiting groove 112 and the second limiting groove 122 extend along the first horizontal direction. The first adjusting member 21 is provided with a first limiting protrusion 211, which slides in cooperation with the first limiting groove 112. The second adjusting member 22 is provided with a second limiting protrusion 221, which slides in cooperation with the second limiting groove 122. A first limiting groove 112 that slides and engages with the first limiting protrusion 211 is added to the groove wall of the first sliding groove 111, and a second limiting groove 122 that slides and engages with the second limiting protrusion 221 is added to the groove wall of the second sliding groove 121. This enhances the limiting effect on the first adjusting member 21 and the second adjusting member 22 in the first horizontal direction, further improves the sliding stability of the first adjusting member 21 in the first sliding groove 111 and the sliding stability of the second adjusting member 22 in the second sliding groove 121, and significantly improves the position adjustment stability of the first frame structure 11 and the second frame structure 12 in the first horizontal direction. Furthermore, the first adjusting member 21 may be provided with first limiting protrusions 211 on both sides of the vertical direction, and the upper and lower walls of the first sliding groove 111 are respectively provided with first limiting grooves 112 corresponding to the two first limiting protrusions 211. The second adjusting member 22 may be provided with second limiting protrusions 221 on both sides of the vertical direction, and the upper and lower walls of the second sliding groove 121 are respectively provided with second limiting grooves 122 corresponding to the two second limiting protrusions 221, so as to improve the anti-overturning performance of the first adjusting member 21 in the first sliding groove 111 and the anti-overturning performance of the second adjusting member 22 in the second sliding groove 121.

[0038] In some other embodiments, the first adjusting member 21 is provided with a first roller on the side near the wall of the first slide groove 111, and the second adjusting member 22 is provided with a second roller on the side near the wall of the second slide groove 121. The first adjusting member 21 is rolled in the first slide groove 111 by the first roller, and the second adjusting member 22 is rolled in the second slide groove 121 by the second roller. The first roller and the second roller reduce the movement resistance of the first adjusting member 21 and the second adjusting member 22 in the first horizontal direction, thereby reducing the difficulty of adjusting the distance between the first frame structure 11 and the second frame structure 12 in the first horizontal direction.

[0039] Optionally, the first frame structure 11 also includes fasteners. The groove wall of the first slide 111 is provided with a plurality of first locking holes spaced apart along a first horizontal direction. The first adjusting member 21 is provided with a second locking hole. The first adjusting member 21 can move until the second locking hole connects with any of the first locking holes. The fastener can pass through the first locking hole into the second locking hole to lock the first adjusting member 21 and the first frame structure 11. The multiple first locking holes provide multiple preset locking positions for the first adjusting member 21. The connection between the second and first locking holes and the locking effect of the fasteners achieves the fixation of the first adjusting member 21 in each preset locking position, ensuring the positioning accuracy and reliability of the first adjusting member 21. This avoids deviations in the water spraying operation of the multiple nozzles 14 located on the first frame structure 11 due to the first adjusting member 21 deviating from its preset locking position after reaching its position. The fasteners enhance the positioning accuracy of the first frame structure 11, thereby ensuring the stable operation of the multiple nozzles 14 for tunnel lining maintenance. Similarly, the second slide 121 has multiple third locking holes spaced apart along the first horizontal direction on its groove wall, and the second adjusting member 22 has a fourth locking hole. The second adjusting member 22 can move until the fourth locking hole connects with any of the third locking holes. With the help of fasteners, the second adjusting member 22 can be locked to the second frame structure 12, thereby improving the positioning accuracy of the second frame structure 12. The fasteners can be locking pins or bolts, etc., and are not specifically limited here.

[0040] Specifically, the first frame structure 11 includes a first support frame 113 and a first arc-shaped mounting frame 114. A first groove 111 is formed in the first support frame 113, and the first arc-shaped mounting frame 114 is fixedly mounted on the first support frame 113. The second frame structure 12 includes a second support frame 123 and a second arc-shaped mounting frame 124. A second groove 121 is formed in the second support frame 123, and the second arc-shaped mounting frame 124 is fixedly mounted on the second support frame 123. Both the first arc-shaped mounting frame 114 and the second arc-shaped mounting frame 124 are evenly spaced with multiple nozzles 14 along their circumference. The use of the first arc-shaped mounting frame 114 and the second arc-shaped mounting frame 124 improves the applicability of the first frame structure 11 and the second frame structure 12 to the shape of the tunnel lining. Compared with a straight mounting frame, it expands the coverage area for tunnel lining maintenance operations and reduces blind spots in tunnel lining maintenance. Multiple nozzles 14 are evenly spaced along the circumference of the first arc-shaped mounting frame 114 and the second arc-shaped mounting frame 124. The water supply effect of the water supply component 13 ensures uniform curing of the tunnel lining and guarantees the quality of tunnel lining curing. The first support frame 113 and the second support frame 123 provide stable support for the curing operation of the nozzles 14 and the adjustment process of the spacing adjustment component 2, ensuring the structural stability of the trolley body 1.

[0041] More specifically, the trolley body 1 also includes a first lifting member 15 and a second lifting member 16, the first frame structure 11 also includes a first support base 115, the first lifting member 15 is fixedly disposed on the first support base 115, and the lifting drive end of the first lifting member 15 is connected to the first support frame 113, the first lifting member 15 can drive the first support frame 113 to lift; the second frame structure 12 also includes a second support base 125, the second lifting member 16 is fixedly disposed on the second support base 125, and the lifting drive end of the second lifting member 16 is connected to the second support frame 123, the second lifting member 16 can drive the second support frame 123 to lift. The first lifting component 15 enables the lifting process of the first support frame 113, thereby achieving height adjustment of the nozzle 14 on the first arc-shaped mounting frame 114 connected to the first support frame 113 relative to the tunnel lining. The second lifting component 16 enables the lifting process of the second support frame 123, thereby achieving height adjustment of the nozzle 14 on the second arc-shaped mounting frame 124 connected to the second support frame 123 relative to the tunnel lining. In other words, the first lifting component 15 and the second lifting component 16 improve the versatility of the tunnel lining maintenance trolley for maintaining tunnel linings of different heights, ensuring the maintenance quality of the tunnel lining.

[0042] In one embodiment, multiple nozzles 14 are fixedly mounted on the first frame structure 11 and the second frame structure 12 to improve the stability of tunnel lining maintenance operations. In another embodiment, multiple nozzles 14 are rotatably mounted on the first frame structure 11 and the second frame structure 12 to expand the maintenance range of the nozzles 14 on the tunnel lining and improve maintenance efficiency.

[0043] Optionally, such as Figure 3 and Figure 5As shown, the first frame structure 11 further includes a first reinforcement unit 116, which includes a first connecting reinforcement 1161 and a second connecting reinforcement 1162 that are set at an angle and fixedly connected. The end of the first connecting reinforcement 1161 away from the second connecting reinforcement 1162 is fixedly connected to the first support frame 113, and the end of the second connecting reinforcement 1162 away from the first connecting reinforcement 1161 is fixedly connected to the first arc-shaped mounting frame 114. The second frame structure 12 further includes a second reinforcement unit 126, which includes a third connecting reinforcement 1261 and a fourth connecting reinforcement 1262 that are set at an angle and fixedly connected. The end of the third connecting reinforcement 1261 away from the fourth connecting reinforcement 1262 is fixedly connected to the second support frame 123, and the end of the fourth connecting reinforcement 1262 away from the third connecting reinforcement 1261 is fixedly connected to the second arc-shaped mounting frame 124. The first connecting reinforcement 1161 and the second connecting reinforcement 1162 are arranged at an included angle and fixedly connected, which enhances the connection strength between the first support frame 113 and the first arc-shaped mounting frame 114 and improves the load-bearing capacity of the first frame structure 11 in multiple directions. The third connecting reinforcement 1261 and the fourth connecting reinforcement 1262 are arranged at an included angle and fixedly connected, which enhances the connection strength between the second mounting frame and the second arc-shaped mounting frame 124 and improves the load-bearing capacity of the second frame structure 12 in multiple directions.

[0044] For example, the first frame structure 11 and the second frame structure 12 are both made of steel to improve the structural strength of the first frame structure 11 and the second frame structure 12, extend the structural service life of the trolley body 1, and reduce the maintenance and replacement costs of the tunnel lining maintenance trolley.

[0045] In this embodiment, as Figure 1 and Figure 6 As shown, the water supply assembly 13 includes a water tank 131, a water supply pipe 132, and a water pump. One end of the water supply pipe 132 is connected to the water tank 131 containing water, and the other end is connected to a plurality of nozzles 14 via the first frame structure 11 and the second frame structure 12. The water pump is installed on the water supply pipe 132 to drive water from the water tank 131 to the nozzles 14 to ensure the smooth operation of the water spraying maintenance work at the nozzles 14.

[0046] Optionally, the tunnel lining curing trolley also includes a water collection container for collecting curing water flowing down from the tunnel lining. The water collection container ensures a dry and clean environment for tunnel lining curing, avoids the risk of slipping and falling for construction workers, and prevents the curing water from mixing with residual construction materials on the ground to form mortar, thus reducing subsequent cleaning costs.
