Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel lining maintenance and relates to a spray maintenance device for tunnel secondary lining. Background Art

[0002] After the construction of the secondary lining layer of the tunnel is completed, the secondary lining layer needs to be sprayed and maintained regularly to keep a certain humidity in the secondary lining layer, thereby avoiding deformation and cracking of the secondary lining layer.

[0003] In the existing technology, a spray trolley is usually used to spray and maintain the tunnel lining layer. The trolley is set up along the track, and a number of pipes and nozzles are set on the trolley corresponding to the contour of the tunnel secondary lining layer. Water is sprayed onto the secondary lining layer through the pipes and nozzles to spray and maintain the secondary lining layer.

[0004] To ensure complete spray coverage of the secondary lining, numerous nozzles and pipes must be installed on the trolley, making the existing spray maintenance trolley structure complex and difficult to maintain. Reducing the number of pipes and nozzles will result in dead corners in the spray area, preventing the secondary lining from being fully sprayed.

[0005] Therefore, in order to solve the above-mentioned technical problems existing in the existing spray curing trolley, the utility model discloses a spray curing device for tunnel secondary lining. Utility Model Content

[0006] The purpose of the utility model is to provide a spray curing device for tunnel secondary lining, which can perform full-coverage swing spray curing on the tunnel secondary lining layer to avoid spray dead corners.

[0029] Example 1:

[0030] A spray curing device for tunnel secondary lining according to this embodiment, such as Figure 1 and Figure 2 As shown, the mobile trolley 1 includes a curved support 2 provided on the mobile trolley 1. Several swing mechanisms 3 are provided on the side of the curved support 2 close to the tunnel lining. A water pipe 4 is connected to the swinging end of the swing mechanism 3. Several nozzles 5 are provided on the side of the water pipe 4 close to the tunnel lining. A water pipe 10 is connected to the side of the water pipe 4 away from the tunnel lining. Also included is a water tank 9 provided on the mobile trolley 1. A water pump is provided inside the water tank 9 and is connected to the water pipe 10.

[0031] A mobile trolley 1 is mounted on pre-laid tracks within the tunnel, driving the remaining equipment or structures along the tunnel. A curved support 2 is mounted on top of the trolley 1. This curved support 2 conforms to the contour of the tunnel lining, allowing the water spray pipe 4 to be positioned as close as possible to the conforming tunnel lining. Several swing mechanisms 3 are installed on the curved support 2 along the contour of the tunnel lining. The number and placement of these swing mechanisms 3 ensure that all swing mechanisms 3 swing the water spray pipe 4 to an angle sufficient to fully cover the tunnel lining. Spray water is delivered to the water spray pipe 4 via a water pipe 10. This water is evenly sprayed onto the tunnel lining through several nozzles 5 located on the side of the water spray pipe 4 closest to the tunnel lining, providing spray curing. Furthermore, the reciprocating swing of the water spray pipe 4 by the swing mechanism 3 increases the final spray area and spray angle, reducing the use of the water spray pipe 4 and nozzles 5 and preventing blind spots in the tunnel lining during spray curing.

[0032] Example 2:

[0033] A spray curing device for tunnel secondary lining, such as Figure 2 As shown, based on the improvement of Example 1, a first counterweight balancing frame 6 is provided at the end of the water spray pipe 4 close to the swing mechanism 3, and the first counterweight balancing frame 6 is connected to the swing end of the swing mechanism 3 via a rotating shaft. A second counterweight balancing frame 7 is provided at the end of the water spray pipe 4 away from the swing mechanism 3, and the second counterweight balancing frame 7 is rotatably connected to the bearing seat via a rotating shaft.

[0034] The first counterweight balancing frame 6 and the second counterweight balancing frame 7 are symmetrically arranged at both ends of the water spray pipe 4, so that the two ends of the water spray pipe 4 remain balanced. At the same time, by arranging the first counterweight balancing frame 6 and the second counterweight balancing frame 7, the reciprocating swing of the water spray pipe 4 can also be made more stable.

[0035] The rest of this embodiment is the same as that of embodiment 1, so it will not be described again.

[0036] Example 3:

[0037] A spray curing device for tunnel secondary lining, such as Figure 1 As shown, based on the improvement of Example 1 or 2, a quick connector 8 is provided on the side of the water spray pipe 4 away from the tunnel lining layer, and the quick connector 8 is correspondingly plugged into the water pipe 10. By providing the quick connector 8, a convenient and quick connection of the water pipe 10 and the water spray pipe 4 is achieved.

[0038] The rest of this embodiment is the same as that of embodiment 1 or 2, and thus will not be described in detail.

[0039] Example 4:

[0040] A spray curing device for tunnel secondary lining, improved on the basis of any one of embodiments 1-3, such as Figure 3-Figure 5 As shown, the swing mechanism 3 includes a first driving half gear 31, a first intermediate gear 32, a first driven gear 33, a second driving half gear 34, a second driven gear 35, a reduction drive motor 36, and an output shaft 37. The first driving half gear 31 and the second driving half gear 34 are sleeved on the output shaft of the reduction drive motor 36, and the first driving half gear 31 and the second driving half gear 34 are arranged in opposite phases; the first driven gear 33 and the second driven gear 35 are sleeved on the output shaft 37, the first driving half gear 31 is meshed with the first driven gear 33 through the first intermediate gear 32, the second driving half gear 34 is meshed with the second driven gear 35, and the output shaft 37 is connected to the rotating shaft.

[0041] The first drive half gear 31, the first intermediate gear 32, and the first driven gear 33 mesh together to form a first transmission structure, and the second drive half gear 34 meshes with the second driven gear 35 to form a second transmission structure. The first drive half gear 31 and the second drive half gear 34 are arranged in opposite phases, which means:

[0042] When the first drive half gear 31 is meshed with the first intermediate gear 32, the second drive half gear 34 is disengaged from the second driven gear 35. When the first drive half gear 31 is disengaged from the first intermediate gear 32, the second drive half gear 34 is meshed with the second driven gear 35. The first drive half gear 31, the first intermediate gear 32, and the first driven gear 33 are sequentially meshed, such that the rotation direction of the first driven gear 33 is the same as that of the first drive half gear 31. The second drive half gear 34 is directly meshed with the second driven gear 35, such that the rotation direction of the second drive half gear 34 is opposite to that of the second driven gear 35, while the rotation directions of the first drive half gear 31 and the second drive half gear 34 are the same. The opposite phase arrangement of the first drive half gear 31 and the second drive half gear 34 drives the output shaft 37 to rotate periodically, ultimately driving the water spray pipe 4 to rotate periodically.

[0043] Furthermore, the transmission ratio among the first driving half gear 31 , the first intermediate gear 32 , and the first driven gear 33 is 1:1:1; and the transmission ratio between the second driving half gear 34 and the second driven gear 35 is 1:1.

[0044] Furthermore, a sealed waterproof cover is provided on the outside of the swing mechanism 3 to protect the swing mechanism 3 and prevent the swing mechanism 3 from contacting the spray water.

[0045] The rest of this embodiment is the same as any one of Embodiments 1-3, so it will not be described again.

[0046] The above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the present invention.
