Description

Technical Field

[0001] The utility model relates to the technical field of bridges, and particularly relates to a platform for bridge inspection. Background Art

[0002] After the completion of bridge construction, in order to ensure its long-term safe use and extend its service life, regular inspection and maintenance work is particularly important. In this process, inspectors need to conduct a comprehensive and detailed inspection of the bridge. Once problems are found, corresponding maintenance measures can be taken promptly. However, the special structure of the bridge, especially its beam slabs are usually located below the bridge deck, and the width of the bridge deck is often greater than the width of the beam slabs, which poses challenges to the inspection and maintenance work.

[0003] Chinese Patent CN218756984 U discloses a maintenance platform for bridge inspection, which can adapt to harsh weather conditions such as strong winds to a certain extent and ensure firm fixation on the bridge surface. When the platform is hoisted below the bridge deck by hoisting, due to the width difference between the bridge deck and the beam slabs, the platform often cannot closely adhere to the beam slabs but has a certain horizontal distance. If this distance is too large, it will not only significantly increase the difficulty of inspection and maintenance, but also may affect the normal operation of the staff, and even have an adverse impact on the comprehensiveness and accuracy of bridge inspection. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The present utility model will be further described in conjunction with the drawings and embodiments:

[0020] As Figures 1 - 4As shown in the figure, a platform for bridge inspection includes a hoisting frame 1. A translation plate 2 is slidably fitted inside the hoisting frame. This design allows the translation plate to slide stably inside the hoisting frame. This sliding fit design ensures the stability of the translation plate during movement, providing a reliable basis for the inspection work. A driving mechanism is provided between the hoisting frame and the translation plate. The use of the driving mechanism makes the movement of the translation plate more convenient, greatly improving the efficiency of the inspection work. The driving mechanism can drive the translation plate to move relative to the hoisting frame. Four steel wire ropes 4 are provided at the bottom of the translation plate, and the lower ends of the steel wire ropes are connected to a hanging basket 5. This structure is used to carry inspection personnel and inspection tools. The firmness and durability of the steel wire ropes ensure the stability of the hanging basket in the air, providing a safe working environment for inspection personnel. A wire mesh 6 is detachably installed between adjacent steel wire ropes. This design not only provides additional safety protection but also is convenient for disassembly when needed. The detachable design of the wire mesh enables inspection personnel to conduct inspection work more flexibly when needed without being restricted by the wire mesh. A manhole 22 for people to pass through is formed in the middle of the translation plate. This design allows inspection personnel to easily climb into the hanging basket.

[0021] People can climb along the manhole to the inside of the hanging basket with the help of the wire mesh. Then the driving mechanism acts, causing the translation plate to move along the hoisting frame, making the hanging basket close to the beam slab of the bridge for people to facilitate inspection.

[0022] Furthermore, lifting rings 11 are provided at the four corners of the hoisting frame for firmly suspending the entire platform on the bridge. The design of the lifting rings ensures the stability of the entire platform in the air, providing a solid foundation for the inspection work.

[0023] In at least one embodiment, the driving mechanism includes an electric cylinder 3. A fixed block 12 is provided on the hoisting frame. The electric cylinder is fixedly connected to the translation plate, and the telescopic rod of the electric cylinder is installed on the fixed block.

[0024] Furthermore, a sliding groove is provided in the middle of the hoisting frame, and the translation plate is slidably fitted inside the sliding groove.

[0025] Furthermore, sliding blocks 21 are provided on both sides of the translation plate, and the sliding blocks are matched with the sliding groove.

[0026] As Figure 3 shown in the figure, in this embodiment, the wire mesh is detachable. A hinge seat 74 is provided on the hanging basket. An installation pipe 73 is provided on the hinge seat. A rotating shaft 71 is rotatably connected inside the installation pipe. The wire mesh 6 is connected to the rotating shaft. The wire mesh is connected to the steel wire rope through a connecting member. The rotatable and detachable design of the wire mesh provides greater flexibility for inspection personnel, enabling them to adjust according to actual needs.

[0027] Further, the connecting member includes a U-shaped plate 81, and two through holes are provided on the U-shaped plate. When the steel wire rope and the rope net are clamped inside the U-shaped plate, the bolt 82 passes through the two through holes in sequence and is tightened and fixed by the nut 83. The design of the connecting member makes the disassembly of the rope net simpler and faster, improving the efficiency of the inspection work.

[0028] Working mode: Ensure that the four corner rings of the lifting frame are correctly installed and fixed. Check whether the translation plate is in the sliding groove of the lifting frame and ensure that the sliding block fits well with the sliding groove. Fix the electric cylinder on the translation plate and connect its telescopic rod to the fixed block on the lifting frame. Install four steel wire ropes at the bottom of the translation plate and ensure that the lower ends of the steel wire ropes are firmly connected to the hanging basket. Install a rope net between adjacent steel wire ropes and ensure that the connecting members (such as U-shaped plates, bolts, and nuts) between the rope net and the steel wire ropes are correctly installed.

[0029] People can climb along the manhole in the middle of the translation plate and enter the hanging basket with the help of the rope net. Start the electric cylinder to make its telescopic rod move, thereby driving the translation plate to move along the sliding groove of the lifting frame. By controlling the telescopic movement of the electric cylinder, the hanging basket is brought close to the beam slab of the bridge. Since the gap of the rope net is large enough, it does not prevent people from carrying out inspection work. After the inspection is completed, the translation plate is moved back to its original position by controlling the electric cylinder.

[0030] If people need to disassemble the rope net for in-depth inspection, the connecting members between the rope net and the steel wire rope (such as loosening the bolts and nuts) can be removed to separate the rope net from the steel wire rope, so that people can reach out to carry out the inspection work of the bridge.

[0031] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
