[0031] As Figure 1 , Figure 2 shown in the figure, a curing trolley with the function of sidewall roughening disclosed in this embodiment mainly includes a main body framework 1, a traveling system 2, a curing spraying system 11, a roughening machine 5 and a plurality of operation platforms 3.

[0032] The traveling system 2 is arranged at the bottom of the main body framework 1, the operation platforms 3 are arranged at the top and both sides of the main body framework 1, and on the side of the main body framework 1, two or more operation platforms 3 are distributed at intervals in the vertical direction, and adjacent operation platforms 3 are connected by a ladder 4. The curing spraying system 11 is arranged on the main body framework 1 and / or the operation platforms 3. Among them, the main body framework 1, the operation platforms 3, the ladder 4, the curing spraying system 11 and the traveling system 2 together constitute the basic functional part of the curing trolley, and its specific implementation structure and assembly form are the same as those of the existing conventional curing trolley, so this embodiment will not elaborate on it anymore. The roughening machine 5 adopts a common model on the market, and this embodiment will not elaborate on it either.

[0033] The roughening machine 5 is arranged on the main body framework 1 and / or the operation platforms 3. By taking advantage of the fact that the tunneling roughening operation and the curing operation are both between the formation of the secondary lining and the casting of the concrete for the drainage channel and cable trench, the roughening machine 5 is mounted on the curing trolley, so that the curing trolley combines the functions of curing and roughening, thereby improving the functionality of the curing trolley and the convenience of tunnel curing and roughening construction.

[0034] In this embodiment, there are two implementation methods for installing the roughening machine 5 on the curing trolley.

[0035] In the first installation implementation mode of the haircutting machine 5, a haircutting machine placement station is provided on part or all of the working platforms 3 and / or the main frame 1, and the haircutting machine 5 is placed on the haircutting machine placement station. There can be one or more haircutting machines 5, and the number of haircutting machine placement stations is the same as the number of haircutting machines 5. Or in order to save costs, the number of haircutting machine placement stations can be more than the haircutting machines 5, for example, only one haircutting machine 5 is carried on the maintenance trolley, and a haircutting machine placement station is arranged on each working platform 3 and the column of the main frame 1, and the staff can freely choose to place the haircutting machine 5 on a haircutting machine placement station for easy access during work.

[0036] To be more specific, the placement station of the haircutting machine is set on the working platform 3 and the main frame 1 at a position that will not interfere with other equipment on the maintenance trolley and will not hinder the walking of the staff. For example, a box with an open top is arranged at the corner of the working platform 3 as the placement station of the haircutting machine, or a plurality of steel bars are welded at the corner of the working platform 3 to form a fence, so that the fence cooperates with the side guard frame of the working platform 3 to form a placement groove, which can also be used as the placement station of the haircutting machine; a box or a placement groove can also be welded on the corner column of the main frame 1 as the placement station of the haircutting machine.

[0037] Preferably, a movable locking structure is provided on the placement station of the haircutting machine to lock the haircutting machine 5 on the placement station of the haircutting machine. For example, when the placement station of the haircutting machine is a box body arranged at the corner of the working platform 3 or the corner column of the main frame 1, the locking structure can be directly set as a box cover. Or when the placement station of the haircutting machine is a placement groove surrounded by steel bars, the locking structure can be set as a groove cover hinged on the top of the placement groove.

[0038] Under the first installation implementation mode of the hair cutting machine 5, when the maintenance trolley performs maintenance work, the hair cutting machine 5 is locked on the hair cutting machine placement station. When the maintenance trolley needs to perform hair cutting work, the staff member takes out the hair cutting machine 5 from the hair cutting machine placement station and holds the hair cutting machine 5 to perform hair cutting work.

[0039] In the second installation embodiment of the hair cutting machine 5, the hair cutting machine 5 is suspended at the bottom of the lowest working platform 3 on the side of the main frame 1 by a rope 6, for example Figure 1 , Figure 2 During the roughening construction, the worker can hold the suspended roughening machine 5 to complete the roughening operation on the old concrete surface without having to lift the roughening machine 5, thereby reducing the labor intensity of the worker. Among them, at least one roughening machine 5 can be suspended at the bottom of the working platform 3 on one side of the main frame 1, or at least one roughening machine 5 can be suspended at the bottom of the working platform 3 on both sides of the main frame 1.

[0040] Preferably, a winch 7 can be arranged at the bottom of the working platform 3 where the scarifier 5 is suspended. The scarifier 5 is fixedly connected to the end of the rope 6 of the winch 7. By means of the winch 7, the length of the rope 6 between the scarifier 5 and the bottom of the working platform 3 can be adjusted, enabling the staff to change the working position of the scarifier 5 within a certain range and improving the convenience of scarifying operations. Further preferably, an installation groove can also be welded on the column of the main body framework 1. When scarifying operations are not required, the scarifier 5 can be placed in the installation groove to prevent the rope 6 of the winch 7 from being always in a taut state.

[0041] In the specific implementation process, a first track 8 can be arranged at the bottom of the working platform 3 at the lowermost layer on the side of the main body framework 1, and the first track 8 can be made parallel to the traveling direction of the traveling system 2. Then, the winch 7 is slidably connected to the first track 8 through a sliding trolley 10, for example Figure 3 、 Figure 4 as shown. In this way, the scarifying operation for the entire longitudinal direction of the maintenance trolley can be achieved by one scarifier 5. Among them, the first track 8 can be composed of multiple track segments that are slidably fitted together.

[0042] Alternatively, a second track 9 can be arranged at the bottom of the working platform 3 at the lowermost layer on the side of the main body framework 1, and the second track 9 can be made perpendicular to the traveling direction of the traveling system 2. Then, the winch 7 is slidably connected to the second track 9 through a sliding trolley 10. In this way, for large-section tunnels, the lateral working range of the scarifier 5 is larger, making the maintenance trolley have better versatility. Among them, the second track 9 can be composed of multiple track segments that are slidably fitted together.

[0043] More preferably, a first track 8 and a second track 9 can be arranged at the bottom of the working platform 3 at the lowermost layer on the side of the main body framework 1, with the first track 8 being parallel to the traveling direction of the traveling system 2 and the second track 9 being perpendicular to the traveling direction of the traveling system 2. At the same time, the second track 9 is slidably connected to the first track 8 through a sliding trolley 10, and then the winch 7 is slidably connected to the second track 9 through a sliding trolley 10. Or, the first track 8 is slidably connected to the second track 9 through a sliding trolley 10, and then the winch 7 is slidably connected to the first track 8 through a sliding trolley 10, for example Figure 5 as shown. In this way, both the scarifying operation for the entire longitudinal direction of the maintenance trolley can be achieved by one scarifier 5 and the versatility of the maintenance trolley can be improved. Among them, both the first track 8 and the second track 9 can be composed of multiple track segments that are slidably fitted together, for example Figure 6 as shown.

[0044] Since the dust generated during the scarifying operation can lead to an extremely poor working environment and endanger the health of the operators. Considering that the maintenance trolley is equipped with a maintenance spraying system 11, therefore, preferably in this embodiment, at least one dust removal pipe 12 is provided on the maintenance trolley. The first end of the dust removal pipe 12 is connected to the pipeline of the maintenance spraying system 11 through a tee, and the second end of the dust removal pipe 12 extends to the side of the main body frame 1. Before or during the scarifying operation, the working surface is wetted with water by using the dust removal pipe 12, so as to effectively reduce the generation of dust.

[0045] Further preferably, the second end of the dust removal pipe 12 is a flexible hose structure, and a dust removal control valve is provided on the dust removal pipe 12. So that the staff can adjust the water spraying direction of the dust removal pipe 12 according to the needs, and at the same time control whether to carry out water spraying dust removal through the dust removal control valve. Among them, the dust removal control valve is arranged at a position close to the first end of the dust removal pipe 12, and a hand valve or a solenoid valve can be specifically adopted. In the specific implementation process, hooks or movable clamps can be arranged on the columns of the main body frame 1, so as to fix the second end of the dust removal pipe 12 when the dust removal pipe 12 is not in use, and avoid damage to the dust removal pipe 12 caused by dragging the dust removal pipe 12 during the movement of the maintenance trolley.

[0046] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields are all included in the patent protection scope of the present invention.
