Detailed Description of the Invention
[0016] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0018] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.
[0019] like Figure 1 , Figure 2 , Figure 3 As shown, it is a structural diagram of a prefabricated bridge deck deviation correction and laying device provided by an embodiment of the utility model, including a transverse plate 1, support legs 11 are fixedly installed around the side walls of the transverse plate 1, and rollers 12 are rotatably installed at the bottom ends of the support legs 11. A rotating disk 2 is rotatably installed on the surface of the transverse plate 1, and a bridge deck body 4 is placed below the rotating disk 2. A plurality of groups of suspension rods 3 are arranged on the surface of the rotating disk 2, and a lifting assembly 5 that cooperates with the suspension rod 3 is arranged on the surface of the transverse plate 1, and a positioning assembly 6 that cooperates with the surface of the transverse plate 1 is arranged on the surface of the rotating disk 2. A protective mechanism 7 that cooperates with the suspension rod 3 is arranged on the surface of the rotating disk 2, and the protective mechanism 7 includes a limiting assembly 71 and an adjusting assembly 72, wherein the limiting assembly 71 is located in the rotating disk 2, and the adjusting assembly 72 is located on the surface of the rotating disk 2 and is connected to the limiting assembly 71.
[0020] When in use, push the cross plate 1 to move above the bridge deck body 4 that needs to be lifted. Through the cooperation between the lifting assembly 5 and the suspension rod 3, the bridge deck body 4 can be automatically lifted. After the bridge deck body 4 is lifted, push the cross plate 1 and the bridge deck body 4 to move synchronously. During the lifting process, the limit assembly 7 and the adjustment assembly 72 cooperate with each other to further protect the suspension rod 3. When the lifting assembly 5 fails to pull the suspension rod 3 due to an accident, the limit assembly 71 can automatically position and support the suspension rod 3, effectively preventing the bridge deck body 4 from falling directly. After the bridge deck body 4 moves to a suitable position, when the angle of the bridge deck body 4 needs to be adjusted, the positioning assembly 6 controls the rotating disk 2 to rotate on the surface of the cross plate 1, and the rotating disk 2 drives the bridge deck body 4 to rotate synchronously. After it rotates to a suitable angle, the lifting assembly 5 controls the bridge deck body 4 to automatically fall.
[0021] like Figure 1 ,Figure 2 , Figure 3 As shown in Figure 3 , as a preferred embodiment of the present utility model, the hoisting assembly 5 includes a hook 51 fixedly installed at the bottom end of the suspension rod 3. A lifting ring 54 that cooperates with the hook 51 is arranged on the surface of the bridge deck body 4. The top ends of multiple groups of suspension rods 3 are jointly and fixedly installed with a top plate 52. A hydraulic cylinder 53 is fixedly installed on the surface of the rotating disc 2, and the telescopic end of the hydraulic cylinder 53 is connected to the bottom wall of the top plate 52.
[0022] When in use, when it is necessary to hoist the bridge deck body 4, insert the hook 51 at the bottom end of the suspension rod 3 into the lifting ring 54. The hydraulic cylinder 53 pushes the top plate 52 to move upward. The top plate 52 and the suspension rod 3 cooperate with each other, and the bridge deck body 4 can be lifted off the ground. Push the cross plate 1 to move, and the cross plate 1 can drive the bridge deck body 4 to move synchronously.
[0023] As Figure 1 , Figure 2 , Figure 3 As shown in Figure 2 and Figure 3 , as a preferred embodiment of the present utility model, the positioning assembly 6 includes multiple groups of clamping grooves 61 that are annularly distributed around the rotating disc 2 and are opened on the surface of the cross plate 1. A clamping rod 62 that cooperates with the clamping grooves 61 is rotatably installed on the surface of the rotating disc 2.
[0024] Initially, the clamping rod 62 is inserted into the corresponding clamping groove 61. At this time, the rotating disc 2 is fixedly installed on the surface of the cross plate 1. When it is necessary to adjust the angle of the bridge deck body 4 below the rotating disc 2, rotate the clamping rod 62 to separate the clamping rod 62 from the clamping groove 61. At this time, the rotating disc 2 can be conveniently controlled to rotate on the surface of the cross plate 1, thereby adjusting the angle of the bridge deck body 4. After the bridge deck body 4 moves to the corresponding angle, insert the clamping rod 62 into the corresponding clamping groove 61, and the position of the rotating disc 2 can be fixed again, which is convenient for subsequent hoisting and placing of the bridge deck body 4.
[0025] As Figure 1 , Figure 2 , Figure 3 As shown in Figure 2 and Figure 3 , as a preferred embodiment of the present utility model, the limiting assembly 71 includes a vertical cavity opened inside the rotating disc 2. The suspension rod 3 passes through the vertical cavity. A limiting disc 714 located inside the vertical cavity is fixedly installed on the surface of the suspension rod 3. A receiving groove 711 is opened outward on the side wall of the vertical cavity. A compression spring 712 is fixedly installed in the receiving groove 711, and a protective rod 713 extending into the vertical cavity is fixedly installed at the telescopic end of the compression spring 712.
[0026] During use, when hoisting, the limit disk 714 is located above the protective rod 713 at this time. When the hydraulic cylinder 53 or the top plate 52 releases the pulling of the suspension rod 3, and the suspension rod 3 moves downward under the gravity of the bridge deck body 4, the protective rod 713 can further support and position the limit disk 714, effectively preventing the bridge deck body 4 from falling directly. When it is necessary to normally control the downward movement of the bridge deck body 4, the adjusting assembly 72 controls the protective rod 713 to move into the receiving groove 711. At this time, the protective rod 713 can effectively prevent interference with the movement track of the limit disk 714.
[0027] As Figure 1 , Figure 2 , Figure 3 shown, as a preferred embodiment of the present invention, the adjusting assembly 72 includes a top groove 721 formed on the surface of the rotating disk 2. The bottom wall of the top groove 721 is provided with a wire groove 724 communicating with the receiving groove 711. A control disk 722 is placed in the top groove 721. A pull ring 723 is arranged on the surface of the control disk 722. One end of the protective rod 713 located in the receiving groove 711 is fixedly installed with a pulling rope 725. The pulling rope 725 passes through the wire groove 724 and extends into the top groove 721 and is fixedly connected to the control disk 722.
[0028] During use, when it is necessary to adjust the position of the protective rod 713, the control disk 722 is pulled. The control disk 722 and the pulling rope 725 cooperate with each other to pull the protective rod 713 into the receiving groove 711.
[0029] The working principle of the present invention is: during use, the cross plate 1 is pushed to move above the bridge deck body 4 to be hoisted. The hook 51 at the bottom end of the suspension rod 3 is inserted into the lifting ring 54. The hydraulic cylinder 53 pushes the top plate 52 to move upward. The top plate 52 and the suspension rod 3 cooperate with each other to lift the bridge deck body 4 off the ground. The cross plate 1 is pushed to move, and the cross plate 1 can drive the bridge deck body 4 to move synchronously. When it is necessary to adjust the angle of the bridge deck body 4 below the rotating disk 2, the clamping rod 62 is rotated so that the clamping rod 62 is separated from the clamping groove 61. At this time, the rotating disk 2 can be conveniently controlled to rotate on the surface of the cross plate 1, thereby adjusting the angle of the bridge deck body 4. After the bridge deck body 4 moves to the corresponding angle, the clamping rod 62 is inserted into the clamping groove 61 at the corresponding position to fix the position of the rotating disk 2 again, facilitating the subsequent hoisting and placing of the bridge deck body 4.
[0030] When the hydraulic cylinder 53 or the top plate 52 releases the pulling force on the suspension rod 3 and the suspension rod 3 moves downward under the gravity of the bridge deck body 4, the protective rod 713 can further support and position the limit disc 714, effectively preventing the direct fall of the bridge deck body 4. When it is necessary to normally control the downward movement of the bridge deck body 4, the control disc 722 is pulled. The control disc 722 and the pulling rope 725 cooperate with each other to pull the protective rod 713 into the storage groove 711. At this time, the protective rod 713 can effectively avoid interfering with the movement track of the limit disc 714.
[0031] The above describes the preferred embodiments of the present patent in detail. However, the present patent is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present patent.
