Description

Technical Field

[0001] This utility model relates to the field of bridge-building machine suspender technology, specifically a suspender device for the bottom formwork platform of a bridge-building machine. Background Technology

[0002] A bridge-building machine is a type of mechanical equipment specifically designed for bridge construction. It can automatically or semi-automatically install and construct various bridge components on-site. For example, a lifting device for the bottom formwork platform of a bridge-building machine. The bottom formwork platform refers to the platform used to support and fix the bottom formwork during concrete engineering construction. Before construction, it is necessary to set up formwork for the construction object. The formwork is the bottom formwork platform. The bottom formwork platform is large and needs to be lifted, hence the emergence of a lifting device for the bottom formwork platform of a bridge-building machine.

[0003] Currently available bridge-building machine jacks primarily focus on improving lifting capacity. These jacks typically consist of a jack body, a power mechanism, steel cables, and a hook. The power mechanism inside the long jack pulls the steel cables, causing the hook to lift the bottom formwork platform and move it. However, while existing hooks and cables can lift the platform, it still experiences significant swaying during movement, making it difficult to control and potentially injuring workers. Therefore, a new jack device for bridge-building machine bottom formwork platforms is proposed that reduces horizontal swaying after lifting, preventing injury to workers and promoting safer operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a lifting rod device for the bottom formwork platform of a bridge-building machine. It has the advantages of reducing the horizontal swaying of the bottom formwork platform after it is lifted, avoiding accidental injury to workers, and promoting safe use. It solves the problem that the bottom formwork platform still sways significantly during movement, making it difficult to control the degree of swaying and potentially causing accidental injury to workers.

[0005] To achieve the above-mentioned goal of reducing the horizontal sway of the bottom formwork platform after it is lifted, avoiding accidental injury to workers, and facilitating safe use, this utility model provides the following technical solution: a lifting rod device for the bottom formwork platform of a bridge building machine, including a crane and an electric slide, wherein the bottom of the electric slide is provided with a lifting mechanism;

[0006] The lifting mechanism includes a power box, a motor, a rotating column, a main gear, a chain, an auxiliary gear, a drum, a steel cable, a hanging plate, and a control room. The power box is located at the bottom of the electric slide, and the motor is fixedly installed inside the power box. A rotating column is located at the output end of the motor. A gear is fixedly installed on the outside of the rotating column. A chain meshes with the outside of the gear. A left auxiliary gear meshes with the outside of the chain. A drum is fixedly installed in front of the left auxiliary gear. A steel cable is installed on the outside of the drum. A hanging plate is fixedly connected to the bottom of the steel cable. The control room is located at the top of the crane.

[0007] Furthermore, the number of the motor, rotating column, main gear, chain, auxiliary gear, drum, and steel cable are all two, arranged symmetrically from left to right.

[0008] Furthermore, the bottom of the power box has an opening that is compatible with the two steel cables.

[0009] Furthermore, two multi-stage telescopic rods are fixedly installed at the bottom of the power box. The two multi-stage telescopic rods are arranged symmetrically front and back, and a chain is fixedly connected to the bottom of each of the two multi-stage telescopic rods.

[0010] Furthermore, a number of chain locks are fixedly connected to the bottom of the steel cable, and hooks are fixedly connected to the bottom of each of the chain locks.

[0011] Furthermore, the control room is electrically connected to the crane, electric slide, two motors, and two multi-stage telescopic booms via wires.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] This hoisting device for the bottom formwork platform of a bridge-building machine, through the setting of a lifting mechanism, allows the electric slide to be activated via the control room when lifting is required, positioning the power box at a suitable position on the top of the bottom formwork platform. Several hooks are then attached to the bottom formwork platform, and the motor rotates clockwise, causing the chain drive to cause the drum to wind up the steel cable. The two steel cables on the left and right sides wind up simultaneously, lifting the bottom formwork platform. The two steel cables reduce lateral sway, and the front-to-back sway is reduced by setting two symmetrical multi-stage telescopic rods. This lifting mechanism can reduce the horizontal sway of the bottom formwork platform after it is lifted, preventing accidental injury to workers and promoting safe use. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 In this embodiment, a lifting device for the bottom formwork platform of a bridge building machine includes a crane 1 and an electric slide 2, with a lifting mechanism 3 provided at the bottom of the electric slide 2.

[0022] The lifting mechanism 3 includes a power box 301, a motor 302, a rotating column 303, a main gear 304, a chain 305, an auxiliary gear 306, a drum 307, a steel cable 308, a hanging plate 309, and a control room 3010. The power box 301 is located at the bottom of the electric slide table 2. The motor 302 is fixedly installed inside the power box 301. The rotating column 303 is located at the output end of the motor 302. The main gear 304 is fixedly installed outside the rotating column 303. The chain 305 is meshed outside the main gear 304. The left auxiliary gear 306 is meshed outside the chain 305. The drum 307 is fixedly installed in front of the left auxiliary gear 306. The steel cable 308 is located outside the drum 307. The hanging plate 309 is fixedly connected to the bottom of the steel cable 308. The control room 3010 is located at the top of the crane 1.

[0023] In the implementation of the case, the number of motor 302, rotating column 303, main gear 304, chain 305, auxiliary gear 306, drum 307 and steel cable 308 are all two, arranged symmetrically from left to right. The two steel cables 308 reduce the swaying in the left and right directions. If it sways to the left when being lifted, it will pull the right steel cable 308. Since the steel cable 308 has no elasticity, it cannot sway.

[0024] In the implementation of the case, two multi-stage telescopic rods 5 are fixedly installed at the bottom of the power box 301. The two multi-stage telescopic rods 5 are arranged symmetrically front and back. The bottom of each of the two multi-stage telescopic rods 5 is fixedly connected to a chain 501. By setting two multi-stage telescopic rods 5 symmetrically front and back, the swaying in the front and back direction during the lifting process is reduced.

[0025] In the implementation of this case, the control room 3010 is electrically connected to all electronic components in this patent via wires, thereby controlling all electronic components in this patent by operating the control room 3010.

[0026] When implementing this procedure, please follow these steps:

[0027] 1) When lifting is required, start the electric slide 2 through the control room 3010 to bring the power box 301 to a suitable position on the top of the bottom mold platform;

[0028] 2) Then hang several hooks 601 on the bottom formwork platform;

[0029] 3) Then, the motor 302 rotates clockwise, and the chain 305 drives the drum 307 to wind up the steel cable 308. The two steel cables 308 on the left and right sides are wound up synchronously, and the bottom mold platform is lifted up. The two steel cables 308 reduce the swaying in the left and right directions.

[0030] 4) Finally, by setting two multi-stage telescopic rods 5 symmetrically in front and behind, the swaying in the front and back direction during the lifting process is reduced.

[0031] In summary, the hoisting device for the bottom formwork platform of the bridge-building machine, by setting up a hoisting mechanism 3, allows the electric slide 2 to be activated via the control room 3010 when hoisting is required, so that the power box 301 is positioned at a suitable position on the top of the bottom formwork platform. Several hooks 601 are then hung on the bottom formwork platform. The motor 302 rotates clockwise, and the chain 305 drives the drum 307 to wind up the steel cable 308. The two steel cables 308 on the left and right sides are wound up simultaneously, lifting the bottom formwork platform. The two steel cables 308 reduce the swaying in the left and right directions. By setting up two symmetrical multi-stage telescopic rods 5, the swaying in the front and back directions during the lifting process is reduced. This hoisting mechanism 3 can reduce the swaying of the bottom formwork platform in the horizontal direction after it is lifted, avoiding accidental injury to workers and promoting safe use.
