Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a thrust stopping device for a cable-stayed hanging basket used in bridge construction. Background Technique

[0002] A bridge generally consists of an upper structure, a lower structure, bearings and accessory structures. The upper structure, also known as the bridge span structure, is the main structure for crossing obstacles. The lower structure includes abutments, piers and foundations. The bearing is a force transmission device provided at the supporting place of the bridge span structure and the pier or abutment. The accessory structures refer to approach slabs, tapered revetments, revetments, diversion works, etc. Bridges are not only built for the convenience of crossing large rivers and lakes. Today, with the rapid development, bridges have long become an important part of urban road traffic. In the construction of bridges, cable-stayed hanging baskets are often used to facilitate the continuous construction of bridges.

[0003] Currently, when the cable-stayed hanging basket moves towards the beam end on the track, due to its own weight, a certain impact force will be generated. Therefore, a thrust stopping device for the cable-stayed hanging basket is needed. For example, the existing Chinese patent application number: CN216689078U discloses a thrust stopping device for a cable-stayed hanging basket used in bridge construction. In this scheme, by setting an elastic corrugated pipe and a return spring, when the sliding seat slides to the end of the track, it is easy to generate a large impact force due to the inertial effect of gravity. During the whole process, the elastic corrugated pipe and the return spring can both play a certain buffering role, and the contact with the sliding seat is a soft contact, which can not only play a good thrust stopping role, but also effectively avoid the damage to the sliding seat caused by long-term hard contact.

[0004] The above scheme still has deficiencies. Although it can buffer the sliding seat installed with the cable-stayed hanging basket, so as to realize the thrust stopping effect on the cable-stayed hanging basket, in the actual use process of the current thrust stopping device, when the sliding seat installed with the cable-stayed hanging basket impacts the elastic corrugated pipe and the return spring, the elastic corrugated pipe and the return spring will be squeezed under the impact force. Therefore, after the buffering is over, the sliding seat installed with the cable-stayed hanging basket will be pushed away in the reverse direction under the action of the return force, thus reducing the thrust stopping stability of the device for the cable-stayed hanging basket. Moreover, the position of the buffer assembly in this device is inconvenient to move and adjust, and it is not flexible to use, and cannot be adjusted correspondingly according to the end position where the cable-stayed hanging basket needs to move on the track, thus reducing the practicability of the device.

A power supply device is installed on the bottom plate 1, and the electromagnet 5 is electrically connected to the power supply device. By turning on the power supply device, the electromagnet 5 generates magnetic force, and by turning off the power supply device, the electromagnet 5 has no magnetic force.

[0042] Reinforcing ribs 10 are fixedly connected to the tops of both the adjusting block 45 and the support block 9, and one side of the reinforcing rib 10 is fixedly connected to the surface of the frame body 4.

[0043] Specifically, through the setting of the reinforcing rib 10, the connection part at the bottom of the frame body 4 can be strengthened, thereby improving the firmness of the frame body 4.

[0052] Working principle: During the use of the cable-stayed hanging basket thrust stopping device for bridge construction, first, the power supply device is turned on to make the electromagnet 5 generate magnetic force. When the sliding seat 3 drives the cable-stayed hanging basket to move towards the electromagnet 5 and they come into contact, under the action of the magnetic force, the metal plate 6 on one side of the sliding seat 3 is magnetically attracted to the electromagnet 5. And through the cooperation of the damper 51 and the buffer spring 52, the impact force generated by the movement of the sliding seat 3 and the cable-stayed hanging basket can be greatly weakened during contact, so that the sliding seat 3 stops advancing, so as to realize the function of thrust stopping for the cable-stayed hanging basket. At the same time, the damper 51 can also greatly reduce the resilience after the buffer spring 52 is compressed. And with the magnetic attraction cooperation between the electromagnet 5 and the metal plate 6, the sliding seat 3 and the cable-stayed hanging basket will not be pushed away in the reverse direction by the resilience of the buffer spring 52 after the buffering is over, thus improving the thrust stopping stability of the device for the cable-stayed hanging basket;

[0053] On the other hand, during the use process, first determine the end position required for the cable-stayed hanging basket to move along with the sliding seat 3 on the track 2. Then, by starting the servo motor 41, the output end of the servo motor 41 drives the meshing worm 43 and worm gear 44 to rotate, and drives the screw rod 42 to rotate. Under the action of the thread, the adjusting block 45 drives the frame body 4 to move horizontally, which can facilitate the movement and adjustment of the positions of the frame body 4, the damper 51, the buffer spring 52 and the electromagnet 5. It can be adjusted correspondingly according to the end position where the cable-stayed hanging basket needs to move on the track 2, thus improving the practicability of the device.

[0054] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
