The moving trolley adopts a structure that can automatically move on the circular track according to the existing technology.

[0034] The annular steel bar fixing assembly specifically includes an annular steel bar fixing plate 3, on which a plurality of fixing openings 3a for fixing the annular steel bars are arranged at upper and lower intervals on one side of the annular steel bar fixing plate 3 facing the shaft wall. To achieve the fixation of the annular steel bars, at least two annular steel bar fixing telescopic cylinders 4 are arranged at upper and lower intervals on the annular steel bar fixing plate 3 and are arranged on corresponding columns 2, so that the position of the annular steel bar fixing plate can be adjusted so that the tied steel bar cage can better match the shaft, and the annular steel bar fixing telescopic cylinders 3 and the annular rail 1 are staggered so that the automatic binding assembly will not interfere with the annular steel bar fixing assembly.

[0035] The vertical steel bar positioning assembly includes a vertical steel bar positioning plate 6. To facilitate the positioning of the vertical steel bars after they are placed, a plurality of vertical steel bar clamps 6a are arranged at intervals up and down on the vertical steel bar positioning plate 6.

[0036] The steel bar automatic binding assembly includes a steel bar binding manipulator 9. To achieve the binding of multiple annular steel bars and vertical steel bars, the steel bar binding manipulator 9 is slidably arranged on a vertical travel track 10. A driving assembly for realizing the up and down movement of the steel bar binding manipulator is also arranged between the steel bar binding manipulator and the vertical travel track, and the driving assembly can adopt a screw nut mechanism or a gear rack mechanism, among which the steel bar binding manipulator is a prior art.

The annular steel bar straightening plate 13 is arranged on the corresponding moving trolley 5 through a straightening telescopic bracket 14, and a straightening telescopic cylinder 15 located on both sides of the straightening telescopic bracket is also arranged between each moving trolley 5 and the straightening telescopic bracket 14.

[0038] Preferably, an auxiliary platform 16 is provided on the column 2 to assist in fixing the annular reinforcement on the annular reinforcement fixing assembly, and a staircase with handrails is provided between the auxiliary platform and the bottom to facilitate access to the auxiliary platform, and an inclined support is provided between the auxiliary platform 16 and the column 2, and preferably handrails are also provided on the outside of the working platform and the auxiliary platform.

[0039] To facilitate demoulding of the steel formwork assembly, the steel formwork assembly includes at least two steel formworks, a pouring window 18a is left on the steel formwork 18 for pouring concrete, two adjacent steel formworks 18 are connected by a steel formwork telescopic bracket 23, and a demoulding oil cylinder 24 is arranged inside the steel formwork telescopic bracket 23 between the two adjacent steel formworks 18 for demoulding. When the demoulding oil cylinder is retracted, the distance between the two adjacent steel formworks is shortened, thereby achieving demoulding. To facilitate the hoisting of the steel formwork assembly, a number of template hoisting points are also provided.

[0040] The stabilizing shoe assembly includes a support plate 20 that can be supported on the wall of the shaft. The support plate 20 is arranged on the bearing frame 19 through a corresponding supporting telescopic bracket 21. Stabilizing shoes 22 are arranged on the support plate 20 and the bearing frame 19. The stabilizing shoe 22 includes a vertically arranged shoe cylinder 22a. The upper and lower ends of the shoe cylinder 22a are hinged to the support plate 20 or the bearing frame 19 through corresponding shoe rods 22b, and the shoe rod 22b is connected to the shoe cylinder 22a in an articulated manner. When the shoe cylinder 22a is extended, the support plate can be brought close to the bearing frame, thereby facilitating the up and down movement of the bearing frame. When the shoe cylinder 22a is contracted, the support plate can be moved away from the bearing frame, so that the support plate is against the wall of the shaft and the bearing frame does not move.

[0041] To reduce the moving distance, it is best that the depth of the steel formwork assembly matches the depth of the column, that is, the tied steel cage matches the corresponding casting depth of the steel formwork assembly.

[0042] Based on the above device, a method for automatic steel bar binding and concrete pouring in a shaft is provided, which is also equipped with a hoist located outside the shaft, and the cable of the hoist is fixed on the bearing frame, and before each contraction of the stabilizing shoe assembly (i.e., before the shoe cylinder is extended), it is best to ensure that the hoist cable is in a taut state, including the following steps:

[0043] The first step is to move the entire device into place. First, retract the stabilizing shoe assembly, and then use the hoist to drive the entire device downward until the automatic steel bar binding structure is just below the poured part, then stop moving. At this time, the stabilizing shoe assembly unfolds to support the entire device in the corresponding position.

[0044] Step 2: Steel bar tying. Place the circumferential steel bars and vertical steel bars in order from the top. After all the circumferential steel bars are placed, place the vertical steel bars. At the same time, the steel bar automatic tying structure is used to automatically tie the steel cage during the process of placing the vertical steel bars. The specific operation process is as follows:

[0045] 1. Fixing of multiple annular steel bars. First, insert the annular steel bars into the fixed openings at the same height. When inserting, the insertion is achieved through the joint action of manual labor and the annular steel bar straightening assembly. Specifically, the straightening telescopic cylinder is extended to extend the annular steel bar straightening plate outward for a certain distance, and then the annular steel bars are lowered to the corresponding position. Even if the annular steel bars fall into the positioning opening and are located on the inner side of the anti-drop rod, the straightening telescopic cylinder is retracted to allow the annular steel bars to have the force to be inserted into the fixed opening. When the straightening telescopic cylinder is retracted, the workers work together to insert the annular steel bars into all the fixed openings. Repeat the above work to complete the fixation of multiple annular steel bars.

[0046] 2. Tie the vertical steel bars at the bottom. Align the vertical steel bars with the vertical steel bar clamp and lower them vertically so that the vertical steel bars are located in the vertical steel bar clamp. Then the steel bar tying manipulator works to realize the automatic tying of a vertical steel bar and multiple circular steel bars. After completion, the mobile trolley drives the circular steel bar straightening assembly, the vertical steel bar positioning assembly and the steel bar automatic tying assembly to the next position.

[0047] 3. Form a steel cage. Repeat step 2 until the automatic binding of the steel cage is completed.

[0048] The third step is pouring and demoulding. After the automatic binding of the steel cage is completed, the steel bar fixing telescopic cylinder, the vertical steel bar positioning telescopic cylinder, the steel bar binding telescopic cylinder and the combing telescopic cylinder are retracted to facilitate subsequent operations. The stabilizing shoe assembly is retracted, and the entire device is driven upward by the hoist. At this time, the bound steel cage does not move. When the steel formwork and the bound steel cage are at the same height, the stabilizing shoe assembly is unfolded to support the entire device, and then pouring is carried out through the pouring window. After pouring, the steel formwork assembly is demoulded. After demoulding, wait for the next work.
