Description

Technical Field

[0001] This utility model belongs to the technical field of vertical shaft construction equipment, specifically relating to a steel bar binding device for vertical shafts. Background Technology

[0002] Before pouring concrete for a vertical shaft, loose reinforcing bars need to be tied into a reinforcing cage inside the shaft. Currently, this tying is usually done manually, which is not only labor-intensive but also requires workers to move back and forth, making the tying time long. Chinese patent CN204940820U discloses a rotatable and movable vertical shaft reinforcing bar tying platform. It discloses that multiple fan-shaped scaffoldings are set on vertical rods via horizontal bars to form a platform for workers to stand on. At the same time, there are also traveling wheels at the bottom of the vertical rods that can move on a circumferential track. The platform rotates by the movement of the vertical rods on the circumferential track, thereby realizing the tying of reinforcing bars throughout the entire vertical shaft. In this device, although the movement of workers can be reduced, workers still need to tie the reinforcing bars throughout the process, so the problems of low efficiency and high labor cost still exist. Utility Model Content

Detailed Implementation

[0022] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0023] like Figure 1-6As shown, a rebar tying device for vertical shafts mainly consists of circumferential tracks 1, columns 2, an automatic tying assembly, and circumferential rebar fixing assemblies. At least two circumferential tracks 1 are spaced vertically apart, and all circumferential tracks 1 are supported by multiple columns 2 arranged circumferentially and fixed at their lower ends. An automatic tying assembly, movable on the circumferential tracks 1, is used to tie circumferential and vertical rebars together. At least two columns 2 are equipped with circumferential rebar fixing assemblies for securing the circumferential rebars.

[0024] The circumferential rebar fixing assembly specifically includes a circumferential rebar fixing plate 3. Several fixing ports 3a for fixing circumferential rebars are arranged vertically and horizontally on the side of the circumferential rebar fixing plate 3 facing the shaft wall. To achieve the fixing of the circumferential rebars, at least two circumferential rebar fixing telescopic cylinders 4 are arranged vertically and horizontally on the corresponding columns 2, which can adjust the position of the circumferential rebar fixing plate so that the tied rebar cage can better match the shaft. Moreover, the circumferential rebar fixing telescopic cylinders 4 are misaligned with the circumferential track 1 so that the automatic binding assembly will not interfere with the circumferential rebar fixing assembly.

[0025] The automatic binding assembly includes a mobile trolley 5 mounted on each circumferential track and capable of circumferential movement on the corresponding track. Each mobile trolley 5 is equipped with a vertical rebar positioning component for positioning vertical rebars and a rebar binding component for binding vertical and circumferential rebars. In other words, the mobile trolleys for the vertical rebar positioning and binding components are shared, meaning both components move synchronously circumferentially through the action of multiple mobile trolleys spaced vertically at intervals. Alternatively, separate mobile trolleys can be provided for each circumferential track, with the vertical rebar positioning and binding components mounted separately. To further improve efficiency, at least two mobile trolleys can be mounted on each circumferential track, and all mobile trolleys on the same vertical plane can be equipped with a vertical rebar positioning component, a rebar binding component, and a circumferential rebar straightening component. This means at least two combinations of these components can be mounted circumferentially. The mobile trolley uses existing technology to automatically move on a circular track.

[0026] The vertical rebar positioning assembly includes a vertical rebar positioning plate 6. To facilitate the positioning of the vertical rebar after placement, several vertical rebar clamps 6a are spaced vertically on the vertical rebar positioning plate 6. Preferably, the vertical rebar clamps are staggered vertically from the circumferential track. The vertical rebar clamps have slots or openings for the vertical rebars to pass through. To fix the vertical rebar positioning plate 6, it is mounted on a corresponding moving trolley 5 via a vertical rebar telescopic bracket 7. Each moving trolley 5 and the vertical rebar positioning plate 6 are further connected by vertical rebar positioning telescopic cylinders 8 located on both sides of the vertical rebar telescopic bracket, allowing adjustment of the vertical rebar positioning plate's position and facilitating contact between the circumferential and vertical rebars.

[0027] The rebar tying assembly includes a rebar tying robot 9. To tie multiple circumferential and vertical rebars, the rebar tying robot 9 is slidably mounted on a vertical travel track 10. A drive assembly for the rebar tying robot's vertical movement is also provided between the rebar tying robot and the vertical travel track. This drive assembly can be a screw-nut mechanism or a rack and pinion mechanism, among other mechanisms. The rebar tying robot itself is existing technology. To fix the vertical travel track 10, it is mounted on corresponding moving trolleys 5 via tying telescopic brackets 11. Each moving trolley 5 and the tying telescopic bracket 11 is further equipped with rebar tying telescopic cylinders 12 located on both sides of the tying telescopic bracket, facilitating the removal of the entire assembly from the shaft after completion.

[0028] To prevent the circumferential reinforcing bars in locations without circumferential reinforcing bar fixing plates from falling downwards under gravity, all moving trolleys 5 are also equipped with circumferential reinforcing bar straightening components to maintain the spacing of the circumferential reinforcing bars, and the circumferential reinforcing bar straightening components are located in front of the vertical reinforcing bar positioning components and the reinforcing bar binding components in the direction of movement.

[0029] The circumferential rebar straightening assembly includes a circumferential rebar straightening plate 13. The circumferential rebar straightening plate 13 has several positioning openings 13a spaced vertically for inserting circumferential rebars and several anti-detachment rods 13b to prevent the rebars from detaching from the circumferential rebar fixing assembly. The circumferential rebar straightening plate 13 is mounted on a corresponding moving trolley 5 via a straightening telescopic bracket 14. Each moving trolley 5 and the straightening telescopic bracket 14 are further connected by straightening telescopic cylinders 15 located on both sides of the straightening telescopic bracket.

[0030] Ideally, an auxiliary platform 16 is provided on the column 2 to facilitate the fixing of the circumferential reinforcing bars to the circumferential reinforcing bar fixing assembly, and a staircase with handrails is provided between the auxiliary platform and the bottom to facilitate access to the auxiliary platform. An inclined support is provided between the auxiliary platform 16 and the column 2, and preferably, a handrail is also provided on the outside of the auxiliary platform.

[0031] Ideally, the lower end of the column is fixedly installed on the working platform, and the working platform 17 is installed above the steel formwork 18, and the steel formwork 18 is installed on the support frame 19. Stable support shoe components are provided at intervals on the lower outer side of the support frame 19 to support the shaft wall. The stabilizing support shoe assembly includes a support plate 20 that can be supported on the shaft wall. The support plate 20 is mounted on the bearing frame 19 via a corresponding telescopic support bracket 21. A stabilizing support shoe 22 is provided between the support plate 20 and the bearing frame 19. The stabilizing support shoe 22 includes a vertically arranged support shoe cylinder 22a. Both the upper and lower ends of the support shoe cylinder 22a are hinged to the support plate 20 or the bearing frame 19 via corresponding support shoe rods 22b. The support shoe rods 22b and the support shoe cylinder 22a are connected by a hinge. When the support shoe cylinder 22a extends, it allows the support plate to move closer to the bearing frame, thus facilitating the vertical movement of the bearing frame. When the support shoe cylinder 22a retracts, it allows the support plate to move away from the bearing frame, thus pressing the support plate against the shaft wall and preventing the bearing frame from moving.

[0032] To facilitate demolding of the steel formwork, the steel formwork includes at least two steel formwork arc plates. The steel formwork arc plates are provided with pouring windows to facilitate pouring. The two adjacent steel formwork arc plates are connected by a steel formwork telescopic bracket. A demolding cylinder is also provided between the two adjacent steel formwork arc plates, located inside the steel formwork telescopic bracket, for demolding. When the demolding cylinder retracts, it shortens the distance between the two adjacent steel formwork arc plates, thereby achieving demolding.

[0033] When using the above-mentioned binding device, the following steps are included in the binding of the reinforcing bars:

[0034] 1. Fixing multiple circumferential reinforcing bars. First, insert the circumferential reinforcing bars into the fixing slots at the same height. During insertion, the insertion is achieved through the combined action of manual labor and the circumferential reinforcing bar straightening assembly. Specifically, first, the straightening cylinder is extended and retracted to extend the straightening plate of the circumferential reinforcing bar outward a certain distance. Then, the circumferential reinforcing bar is lowered to the corresponding position, so that the circumferential reinforcing bar falls into the positioning slot and is located inside the anti-detachment rod. Then, the straightening cylinder is retracted, so that the circumferential reinforcing bar has the force to be inserted into the fixing slot. When the straightening cylinder retracts, the workers work together to insert the circumferential reinforcing bars into all the fixing slots. Repeat the above work to complete the fixing of multiple circumferential reinforcing bars.

[0035] 2. Lower vertical reinforcing bar binding. Align the vertical reinforcing bar with the vertical reinforcing bar clamp and lower it vertically so that the vertical reinforcing bar is inside the vertical reinforcing bar clamp. Then the reinforcing bar binding robot works to bind one vertical reinforcing bar with multiple ring reinforcing bars. After completion, the moving trolley drives the ring reinforcing bar straightening component, the vertical reinforcing bar positioning component and the reinforcing bar binding component to move to the next position.

[0036] 3. Form the reinforcing cage. Repeat step 2 until the reinforcing cage is tied.
