Abstract

The utility model discloses an auxiliary pulling structure for railway bridge construction hoisting, which belongs to the technical field of bridge construction, and is characterized in that the auxiliary pulling structure comprises a base, and a rotating structure is arranged at the top of the base. Due to the fact that one end of the steel wire rope is fixed to the fixing sleeve at the top of the lifting rod, sequentially penetrates through the guide holes of the suspension plate, bypasses the traction wheel and then is wound on the winding drum, the winding drum which rotates forwards and backwards can achieve winding and unwinding of the steel wire rope, and therefore the steel wire rope can be wound and unwound through the winding drum which rotates forwards and backwards. Therefore, in the lifting process, the steel wire rope can play an auxiliary traction role on the lifting plate, a lifted object is effectively prevented from greatly shaking, and the stability of the lifted object can be effectively enhanced even if the lifting object encounters interference factors such as wind power and vibration, so that the construction safety and precision are greatly guaranteed.

DETAILED DESCRIPTION

[0026] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all the other embodiments obtained by the ordinary skilled in the art without making creative labor are within the scope of protection of the present utility model.

[0027] Please refer to Figures 1-5 The present utility model provides technical scheme:

[0028] A kind of auxiliary pulling structure of railway bridge construction hoisting is used, including base 1, the top of base 1 is provided with rotating structure 3, the top of rotating structure 3 is bolted with support 4, the top of support 4 is bolted with drive motor 5, the output end of drive motor 5 penetrates the top of support 4, the output end of drive motor 5 is bolted with lead screw 6, the outside of lead screw 6 is connected with lifting rod 7 in screw thread, the rear side of lifting rod 7 is slidably connected in the inside of support 4, the rear side of lifting rod 7 is bolted with hanging plate 8, the top of hanging plate 8 is provided with auxiliary pulling mechanism 9, and the both sides of the bottom of hanging plate 8 are provided with hoisting structure 10;

[0029] Auxiliary pulling mechanism 9 includes reel 91 bolted to the top of the outside of lead screw 6, the rear side of the bottom of support 4 is bolted with suspension plate 92, the outside of suspension plate 92 is provided with guide hole 93, the front side of suspension plate 92 is bolted with traction wheel 94, the top of lifting rod 7 is bolted with fixed sleeve 95, fixed sleeve 95 is fixedly connected with steel wire rope 96 in the inside, the top of steel wire rope 96 penetrates the inside of guide hole 93, the front side of steel wire rope 96 is located at the outside of traction wheel 94, and steel wire rope 96 is wound on the outside of reel 91.

[0030] In the embodiment, when the driving motor 5 is started, the output end of the motor drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected with the lifting rod 7, and the rear side of the lifting rod 7 slides in the support 4 for limiting, the rotation of the screw rod 6 promotes the stable lifting movement of the lifting rod 7 in the support 4. After the lifting rod 7 drives the hanging plate 8 to reach the appropriate position, the hoisting structure 10 can accurately act on the material, ensuring the connection stability of the material during hoisting. In this process, the drum 91 stacked on the outer top of the screw rod 6 also rotates synchronously. Meanwhile, the steel wire rope 96 fixed in the lifting rod 7 top fixing sleeve 95 passes through the guide hole 93 of the hanging plate 92 and the traction wheel 94, and is wound on the drum 91. Therefore, the forward and reverse rotation of the drum 91 can realize the winding and unwinding of the steel wire rope 96. Thus, during the hoisting operation, with the lifting of the lifting rod 7, the steel wire rope 96 will exert an auxiliary pulling force on the hanging plate 8 under the rotation of the drum 91 and the cooperation of the steel wire rope 96 with the traction wheel 94 and the guide hole 93. Especially in the case of wind, vibration and other adverse factors in the bridge construction site, the auxiliary pulling force can effectively limit the shaking of the hanging plate 8, thereby ensuring the stability of the hoisted material, ensuring the construction safety and precision, and reducing the construction risk. The setting of the rotating structure 3 provides more flexibility for the entire hoisting process. When facing the needs of different construction positions and angles, the operator can easily control the rotating structure 3. The rotating structure 3 drives the support 4 stacked on the top to rotate, thereby making the driving motor 5, the screw rod 6, the lifting rod 7, the hanging plate 8, and the auxiliary pulling mechanism 9 and the hoisting structure 10 installed on the support 4 rotate together. Thus, the hoisting direction and position can be accurately adjusted to avoid hoisting dead angles due to the fixed angle of the device, greatly improving the construction efficiency.

Since the main gear 32 is engaged with the secondary gear 33, and the top of the secondary gear 33 is bolted with the bottom of the bracket 4, the rotation of the main gear 32 will drive the secondary gear 33 to rotate, thereby driving the bracket 4 and the driving motor 5, the lead screw 6, the lifting rod 7, the lifting plate 8, the auxiliary pulling mechanism 9 and the lifting structure 10 installed thereon to rotate together. In this way, the operator can easily control the reduction motor 31 according to the needs of different construction positions and angles, realize accurate angle adjustment, avoid the lifting dead angle caused by the fixed angle of the device, greatly improve the construction efficiency, provide more operation flexibility and convenience for the lifting work of railway bridge construction, and enhance the adaptability of the device to different construction scenes.
