[0016] Figure 1 It is a schematic structural diagram of the fabric trolley in the present utility model. Detailed Embodiments

[0017] The features of the present utility model and other related features are further described in detail below through embodiments with reference to the drawings, so as to facilitate the understanding of those skilled in the same industry:

[0018] As Figure 1As shown, the marks in the figure are respectively represented as: the second lining trolley 10, the column 11, the walking beam 12, the first track 13, the rotary placing machine 20, the base 21, the placing pipe 22, the switching mechanism 23, the switching block 231, the switching tube 232, the connecting column 233, the bracket 24, the first pulley 25, the feed pipe interface 30, the pouring port 40, and the placing trolley 100.

[0019] Example: Figure 1 As shown, this embodiment relates to a placing vehicle suitable for longitudinal integrated pouring of the secondary lining, which is used for pouring concrete of the secondary lining vault. The placing vehicle 100 is movably arranged on the top layer of the secondary lining trolley 10. The placing vehicle 100 includes a feed pipe interface 30 located at the rear end of the placing vehicle 100 and a rotary placing machine 20 located at the front end of the placing vehicle 100. The rear end and the front end of the placing machine are the two ends in the longitudinal direction of the secondary lining vault. Among them, the feed pipe interface 30 is used to connect with the longitudinal pouring gun, and the longitudinal pouring gun is used to pour concrete slurry into the feed pipe interface 30. The rotary placing machine 20 includes a seat 21 and a placing pipe 22 rotatably arranged on the seat 21. The rotation plane of the placing pipe 22 is perpendicular to the moving direction of the placing vehicle 100. One end of the placing pipe 22 is connected to the feed pipe interface 30, and the other end of the placing pipe 22 is used to communicate with the pouring port 40 on the secondary lining trolley 10 located on either side of the placing vehicle 100.

[0020] That is, concrete slurry is injected from the longitudinal pouring gun into the feed pipe interface 30, then enters the distribution pipe 22, and then is transported from the distribution pipe 22 to the pouring port 40 for longitudinal pouring of the vault concrete. Since the distribution pipe 22 and the seat body 21 on the rotary distribution machine 20 are rotatably arranged, for example, the distribution pipe 22 can rotate 180 degrees, so that the other end of the distribution pipe 22 can be rotated to communicate with the pouring port 40 on any side of the distribution vehicle 100, thereby realizing pouring through the distribution pipe 22 in batches to connect the pouring port 40, and realizing longitudinal pouring of the vault concrete.

[0021] Therefore, in this embodiment, the material distribution system of the longitudinal slurry pouring trolley can be used for the material distribution of the secondary lining trolley 10, so that the longitudinal pouring gun can be connected with the material distribution system of the secondary lining trolley 10. After pouring to the fourth row of windows, the longitudinal pouring gun can be directly raised into the warehouse to carry out the longitudinal pouring of the vault concrete.

[0022] In this embodiment, a first pulley is provided at the bottom of the material distribution vehicle 100, and a first track 13 is provided on the top layer of the secondary lining trolley 10. The first pulley is rotatably arranged in the first track 13 to realize the longitudinal movement of the material distribution vehicle 100 on the top layer of the secondary lining trolley 10. During the movement, concrete slurry is sequentially injected into each pouring port 40 on the left and right sides of the material distribution vehicle 100, thereby realizing longitudinal pouring.

[0023] In this embodiment, the secondary lining trolley 10 includes columns 11 located on the left and right sides of the distributing truck 100 and a walking beam 12 fixed to the columns 11 and located outside the columns 11. Among them, the columns 11 are arranged at intervals longitudinally and are divided into two longitudinal columns on the left and right. A walking beam 12 is arranged outside each longitudinal column of columns 11. A plurality of pouring ports 40 are located outside the two rows of columns 11 and are also arranged in two longitudinal columns. The distributing truck 100 further includes two transfer mechanisms 23. Each transfer mechanism 23 is movably arranged on a walking beam 12. Each transfer mechanism 23 includes a transfer pipe 232. One end of the transfer pipe 232 is used to communicate with the distributing pipe 22, and the other end of the transfer pipe 232 is used to communicate with or align with the pouring port 40.

[0024] That is to say, the concrete slurry transmitted by the distributing pipe 22 first flows into the transfer pipe 232 and then is conveyed by the transfer pipe 232 into the pouring port 40. Since the distributing truck 100 is located between the two longitudinal columns of columns 11, when the distributing truck 100 moves longitudinally, the distributing pipe 22 that swings left and right will interfere with the columns 11, brackets, etc. inside the trolley. By arranging the movable transfer mechanism 23 on the walking beam 12 outside the columns 11, the distributing pipe 22 on the distributing truck 100 does not need to extend outside the columns 11 but is communicated with the transfer pipe 232, thus avoiding the interference of the distributing pipe 22 with the columns 11, etc. inside the trolley during the movement. By longitudinally moving the transfer mechanism 23, it can be synchronized with the movement of the distributing truck 100, so as to align the transfer pipe 232 with the pouring port 40 one by one.

[0025] In this embodiment, the transfer mechanism 23 further includes a transfer block 231. The transfer pipe 232 is fixedly connected to the transfer block 231. A second pulley is arranged on the transfer block 231, and a second track is arranged on the walking beam 12. The second pulley is rollably arranged in the second track. Exemplarily, a fixing hole can be arranged on the transfer block 231, and the transfer pipe 232 is passed through and fixed in the fixing hole. Through the cooperation of the pulley and the track, the longitudinal movement of the transfer mechanism 23 on the walking beam 12 is realized.

[0026] In this embodiment, second pulleys are arranged at both the bottom and top of the transfer block 231. The second track includes an upper guide rail and a lower guide rail. The transfer block 231 is vertically limited within the upper guide rail and the lower guide rail. By arranging the upper guide rail and the lower guide rail, the stability of the movement of the transfer block 231 can be improved.

[0027] The cloth pipe 22 in this embodiment is telescopic to prevent obstruction by obstacles such as the upright column 11 during the movement. That is to say, when it is necessary to connect with the adapter pipe 232, the cloth pipe 22 is elongated to connect it with the adapter pipe 232. When longitudinal movement is required, first shorten the cloth pipe 22 again, and then longitudinally move the cloth truck 100 and the adapter mechanism 23 until the next position point. After that, elongate the cloth pipe 22 again to connect the cloth pipe 22 with the adapter pipe 232, so as to align with the pouring port 40 at this position.

[0028] In this embodiment, brackets 24 are fixedly arranged on the left and right sides of the seat body 21. The brackets 24 are used to support the cloth pipe 22. Since the concrete slurry conveyed in the cloth pipe 22 is heavy, when the cloth pipe 22 rotates to the left side of the cloth table and communicates with the left adapter pipe 232, the left bracket 24 can support the cloth pipe 22, and when the cloth pipe 22 rotates to the right side of the cloth table and communicates with the right adapter pipe 232, the right bracket 24 can support the cloth pipe 22, thereby increasing the stability of the pipeline. Optionally, grooves can be formed on the brackets 24, and the size of the grooves is adapted to the cloth pipe 22 to limit its longitudinal displacement.

[0029] The adapter pipe 232 in this embodiment is telescopic to prevent obstruction by some obstacles during the movement and also facilitate adjusting the length of the adapter pipe 232 to accurately align with the pouring port 40 at this position.

[0030] In this embodiment, the adapter pipe 232 is L-shaped. Since the height of the pouring port 40 is lower than the height where the cloth pipe 22 is located, by setting the L-shaped adapter pipe 232, it is convenient to shorten the distance between the adapter pipe 232 and the pouring port 40, so that the slurry outlet of the adapter pipe 232 is directly above the pouring port 40 and aligned.

[0031] In some alternative embodiments, the adapter mechanism 23 further includes a connecting column 233. One end of the connecting column 233 is fixedly connected to the adapter block 231, and the other end of the connecting column 233 is connected to the adapter pipe 232. Since the concrete slurry conveyed in the adapter pipe 232 is heavy, in order to ensure that the adapter pipe 232 will not bend or even break due to the load, a connecting column 233 can be obliquely arranged. One end of the connecting column 233 fixes the adapter block 231, and the other end fixes the adapter pipe 232, so as to transfer the force received by the adapter pipe 232 to the adapter block 231 through the connecting column 233, so as to prevent the adapter pipe 232 from bending and being unable to align with the pouring port 40.

[0032] In summary, the beneficial effects of the present utility model are as follows: By arranging a cloth truck that can move longitudinally on the top layer of the secondary lining trolley, an inlet pipe interface connecting a longitudinal pouring gun and a rotatable cloth pipe are arranged on the cloth truck, so that the cloth system of the longitudinal pouring trolley can be used for cloth feeding of the secondary lining trolley, and rapid connection between the longitudinal pouring gun and the cloth system of the secondary lining trolley can be achieved. After pouring to the fourth row of windows, the longitudinal pouring gun can be directly lifted into the bin to directly perform longitudinal pouring of the arch top concrete. The whole process is convenient and flexible, effectively improving the construction efficiency.
