[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1 Figures 1 to 2 This illustration shows an embodiment of the hoisting device of the present invention. The hoisting device of this embodiment includes a track support 1, a movable track 11 mounted on the track support 1, a movable component 2 mounted on the movable track 11, a lifting support 3 mounted on the movable component 2, and a gripping support 4 located below the lifting support 3. The gripping support 4 has gripper assemblies 5 on opposite sides. Preferably, the track support 1 is a portal frame in both front and side views, facilitating its movement across the processing area of ​​the rebar cage 71 and the precast component mold 72 area without obstructing normal operations in these two areas. The movable trolley 21 of the movable component 2 can reciprocate along the movable track 11 via a gear and rack mechanism, sprocket and chain mechanism, etc., ensuring reliable transmission and preventing slippage.

[0029] The hoisting device in this embodiment refers to... Figure 6 As shown, during operation, the lifting support 3 lowers the gripping support 4, and the gripper assemblies 5 on both sides of the gripping support 4 grip the precast component steel cage 71, thus reliably fixing the steel cage 71. Then, the lifting support 3 raises the gripping support 4, steel cage 71, etc., and the moving component 2 moves along the moving track 11, which can move the lifting support 3, gripping support 4, and steel cage 71 as a whole until the steel cage 71 moves above the precast component mold 72. Finally, the lifting support 3 lowers the gripping support 4 and steel cage 71. After the steel cage 71 is placed into the precast component mold 72, the gripper assemblies 5 release the steel cage 71, thus completing the steel cage 71 placement process. The structure is simple, safe, and efficient. After the steel cage 71 placement process is completed, the lifting support 3 rises, and the moving component 2 moves the lifting support 3 in the opposite direction to reset, preparing for the next hoisting process.

[0030] Furthermore, in this embodiment, the gripper assembly 5 includes a first rotating shaft 51, a first rotating drive member 52 for driving the first rotating shaft 51 to rotate, and a plurality of grippers 53 disposed on the first rotating shaft 51. The first rotating shaft 51 and the first rotating drive member 52 are disposed on the gripping bracket 4, and the plurality of grippers 53 are distributed at intervals along the axial direction of the first rotating shaft 51. The first rotating drive member 52 drives the first rotating shaft 51 to rotate in both directions, thereby driving the plurality of grippers 53 on the first rotating shaft 51 to rotate in both directions, so that the grippers 53 can grip and release the rebar cage 71. The multiple grippers 53 can improve reliability and are also conducive to adapting to various specifications of rebar cages 71.

[0031] Furthermore, in this embodiment, the first rotating shaft 51 is provided with a connecting part 511 (e.g., a connecting ear plate), and the first rotating drive member 52 is a telescopic structure (e.g., a hydraulic cylinder, a pneumatic cylinder, etc.). One end of the first rotating drive member 52 is hinged to the gripping bracket 4, and the other end is hinged to the connecting part 511. When the first rotating drive member 52 extends or retracts, it can drive the first rotating shaft 51 to rotate in both directions through the connecting part 511. The structure is simple and has good reliability. Of course, in other embodiments, the first rotating shaft 51 can also be driven to rotate in both directions by a motor or the like.

[0032] Furthermore, in this embodiment, the moving component 2 includes a moving trolley 21 and a moving support 22 mounted on the moving trolley 21. A lifting support 3 is mounted on the moving support 22, and the moving support 22 is equipped with a lifting drive component 23 for driving the lifting support 3 to move up and down. During operation, the moving trolley 21 can drive the moving support 22, the lifting support 3, and other components to move back and forth along the moving track 11. The lifting drive component 23 can then drive the lifting support 3 to move up and down relative to the moving support 22. Preferably, the lifting drive component 23 is a winch. The number of winches can be two or adjusted according to the weight of the reinforcing cage 71. Multiple winches synchronously drive the lifting of the reinforcing cage 71, etc., which can lift heavier reinforcing cages 71 with good safety and reliability. Of course, in other embodiments, the lifting drive component 23 can also be a hydraulic cylinder, a screw and nut mechanism, etc.

[0033] In a preferred embodiment, a lifting guide structure 24 is provided between the lifting bracket 3 and the movable bracket 22. This structure can be, for example, a lifting slide rail and slider, rollers, guide posts and guide sleeves, linear bearings, etc. The lifting guide structure 24 provides guidance for the lifting movement of the lifting bracket 3, preventing deviation and swaying, while also reducing frictional resistance, resulting in a smoother and more stable movement.

[0034] In a preferred embodiment, diagonal braces 25 are provided between the movable support 22 and the movable trolley 21 on opposite sides. The diagonal braces 25 strengthen the connection between the movable support 22 and the movable trolley 21, improving the stability of the movable support 22. Correspondingly, diagonal braces 25 can also be provided between the lifting support 3 and the gripping support 4 to improve the connection strength between them.

[0035] Example 2 Figures 3 to 8 This invention illustrates another embodiment of the hoisting device, which is basically the same as that in Embodiment 1, except that: See details Figures 6 to 8 In this embodiment, the gripping bracket 4 is rotatably connected to the lower part of the lifting bracket 3, and the lifting bracket 3 is provided with a rotary drive mechanism 6 for driving the gripping bracket 4 to rotate up and down. The casting of narrow and tall components is generally done in a horizontal manner, while the steel cage 71, after being processed, is generally transported vertically to the steel cage placement area. During the process of placing the steel cage 71 into the mold, after the gripper assembly 5 grips the vertically placed steel cage 71, the gripping bracket 4, driven by the rotary drive mechanism 6, rotates the steel cage 71 90° to a horizontal state, and then moves it horizontally into the inner cavity of the precast component mold 72, making it more convenient and flexible to use. Of course, the hoisting device of this embodiment is also applicable to steel cages 71 that do not require rotation.

[0036] Furthermore, in this embodiment, the rotary drive mechanism 6 includes a first sprocket 61 and a second rotating shaft (not labeled in the figure). A second sprocket 62 is mounted on the second rotating shaft. The first sprocket 61 and the second sprocket 62 are connected by a chain 63, and one of them is the driving sprocket (i.e., either the first sprocket 61 or the second sprocket 62 is the driving sprocket, for example, it can be driven to rotate by a motor or hydraulic motor). The gripping bracket 4 is connected to the second rotating shaft. When the steel cage 71 is placed vertically, the second sprocket 62 can drive the second rotating shaft to rotate, allowing the gripping bracket 4 to rotate from a vertical state to a horizontal state. The structure is simple and reliable.

[0037] See details Figure 3In this embodiment, the gripper assembly 5 includes a first rotating shaft 51, a first rotating drive member 52 for driving the first rotating shaft 51 to rotate, and a plurality of gripper seats 54 disposed on the first rotating shaft 51. The first rotating shaft 51 and the first rotating drive member 52 are disposed on the gripping bracket 4. The plurality of gripper seats 54 are distributed at intervals along the axial direction of the first rotating shaft 51. The gripper seats 54 are provided with a plurality of rotatable grippers 53, and the plurality of grippers 53 are distributed at intervals along the axial direction of the first rotating shaft 51. During the processing of the reinforcing cage 71, there may be positional errors of the reinforcing bars. The arrangement of reinforcing bars in the reinforcing cage 71 of different precast components is also different. Preferably, the grippers 53 pass through the stirrups of the reinforcing cage 71 to hook the longitudinal reinforcing bars. When multiple rotatable grippers 53 hook into the steel cage 71, the grippers 53 that encounter the stirrups will be obstructed and naturally avoid them, no longer following the rotation to hook the longitudinal steel bars. The other grippers 53 that are not obstructed continue to hook the longitudinal steel bars, and the stirrups will basically not be densely packed. The multiple sets of rotatable grippers 53 effectively ensure that a certain number of grippers 53 on the gripping bracket 4 hook the longitudinal steel bars, ensuring reliable gripping of the steel cage 71.

[0038] In a preferred embodiment, the gripper 53 is connected to the gripper seat 54 via a pin 55. When the gripper 53 encounters a stirrup and is obstructed, it can naturally avoid it. The structure is simple and effective.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
