When the jack 2 is vertically installed in the receiving groove 5, each fixing plate 7 is in contact with the fixing plate 7, so that the clamping groove 8 plays a further role in limiting the position of the jack 2, which is conducive to further ensuring the stability of the position of the jack 2.

[0036] Continue to refer to Figure 2 and Figure 3The installation frame 3 includes a first frame body 301 and a second frame body 302, wherein the first frame body 301 is fixedly installed at the output end of the jack 2, a sliding groove 9 is provided on the top of the first frame body 301, and the second frame body 302 slides in the sliding groove 9 in the vertical direction. When the second frame body 302 slides in the sliding groove 9, the height of the installation frame 3 is adjusted. In order to further ensure the stability of the second frame body 302 when sliding in the vertical direction, the groove wall of the sliding groove 9 is fixedly connected to the limiting block 10, and the second frame body 302 is provided with a limiting groove 11 extending in the vertical direction. The limiting block 10 slides in the limiting groove 11 to further limit the sliding of the second frame body 302.

[0037] Reference Figure 2 The first frame 301 is provided with a fixing hole 12 that is horizontally penetrated, and the second frame 302 is provided with a plurality of adjustment holes 13 that are distributed in the vertical direction. The fixing hole 12 and the adjustment hole 13 are located in the same vertical line. The second frame 302 is fixed to the first frame 301 by a fixing bolt 14 that is penetrated through the fixing hole 12 and one of the adjustment holes 13. When the fixing bolt 14 is fixed to different adjustment holes 13, the height of the installation frame 3 can be adjusted. There are multiple groups of fixing holes 12, adjustment holes 13, and fixing bolts 14 that are evenly distributed in the horizontal direction. In the embodiment of the present application, there are three groups to fully ensure the connection stability of the first frame 301 and the second frame 302 after the positions are adjusted.

[0038] Reference Figure 2 and Figure 3 The walking wheel 4 is rotatably installed on the free end of the second frame 302 away from the first frame 301, and there are multiple walking wheels evenly distributed in the horizontal direction. In the embodiment of the present application, the number of walking wheels 4 is selected as three to ensure the stability of the walking wheel 4 when it moves to abut the bottom of the concrete bridge deck for rolling transportation.

[0039] Reference Figure 3 and Figure 4 The bottom basket 21 of the cable hanging basket is also provided with a support seat 15 and a moving assembly, wherein two support seats 15 are arranged opposite each other, and the tops of the two support seats 15 are provided with support grooves 16 corresponding to the fixing bolts 14, and the support grooves 16 are used to accommodate the fixing bolts 14, and the installation frame 3 is located between the two support seats 15. After the jack 2 pushes out the running wheel 4, the fixing bolts 14 and the support grooves 16 are located at the same height, so that when the fixing bolts 14 are accommodated in the support grooves 16, the fixing bolts 14 and the installation frame 3 are further supported, thereby fully ensuring the stability of the position where the jack 2 pushes out the running wheel 4. A buffer pad 17 is fixedly connected to the support groove 16 by bonding, and the material of the buffer pad 17 is selected as rubber, so that when the fixing bolts 14 are accommodated in the support grooves 16, it is not easy to be worn due to friction with the groove wall of the support groove 16.

[0040] Reference Figure 4 The motion assembly includes a motion motor 18, a bidirectional screw 19 and a guide rod 20.

The two ends of the bidirectional screw 19 with opposite thread rotation directions are respectively passed through the two support seats 15 and threadedly matched with the two support seats 15. The guide rod 20 is arranged in parallel with the bidirectional screw 19 and fixedly mounted on the bottom basket 21 of the cable hanging basket. The guide rod 20 passes through the two support seats 15 and slides with the two support seats 15, so that the motion motor 18 drives the bidirectional screw When the rod 19 rotates, the two support seats 15 cooperate with the threads of the bidirectional screw 19 and move towards or away from each other under the guidance of the guide rod 20, so that when the walking wheel 4 moves in the vertical direction, the two support seats 15 are not easy to interfere with other components such as the walking wheel 4, which is convenient for ensuring the stability of the walking wheel 4 when it moves in the vertical direction. After the walking wheel 4 moves in the vertical direction, the two support seats 15 can move quickly towards each other under the drive of the motion motor 18, which is convenient for the two support seats 15 to quickly achieve stable support for the position of the walking wheel 4.

[0041] The implementation principle of the walking wheel device after the self-lifting of the cable hanging basket in the embodiment of the present application is as follows: when the jack 2 drives its own output end to move, the installation frame 3 drives each walking wheel 4 to move together in the direction close to or away from the bottom of the concrete bridge deck. When the walking wheel 4 abuts against the bottom of the concrete bridge deck, it is convenient to pull the cable hanging basket and cooperate with the walking wheel 4 to stably move the bottom basket 21 to the next section to be poured. By driving the movement of the output end of the jack 2, each walking wheel 4 can be quickly moved to a state of abutting against the bottom of the concrete bridge deck. The operation is simple and conducive to improving work efficiency. After the walking wheel 4 is lifted up, the two support seats 15 quickly move in the direction close to each other under the drive of the motion motor 18 so that the fixing bolts 14 are accommodated in the support groove 16, which facilitates the two support seats 15 to achieve stable support for the position of the walking wheel 4.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
