Description

TECHNICAL FIELD

[0001] The utility model relates to bridge tower crane technical field, especially a cross-sea bridge pier tower crane driver's convenient road. BACKGROUND

[0002] In many large cross-sea bridge constructions, construction elevators are equipped near tower cranes. These elevators are usually attached to piers or other auxiliary structures, and when tower crane operators finish their work, they can enter the construction elevators through the passages connecting the tower crane operating rooms and the construction elevator entrances (such as simple trestle bridges or platform passages), and then take the elevators to reach the ground or other designated work platforms.

[0003] Through retrieval, the patent with the publication number CN210193252U discloses a climbing frame attached tower crane driver passage, which comprises a passage frame and a protective member installed at one end of the passage frame. One end of the passage frame is detachably connected with the climbing frame, and the protective member is located at the end of the passage frame close to the climbing frame. The passage frame comprises two symmetrically vertically arranged steel plates and two horizontally symmetrically arranged net-shaped plates. The two steel plates are respectively fixedly connected to the upper and lower ends of the inner side walls of the net-shaped plates. After the tower crane and the climbing frame are lifted to a higher position, a fixed passage frame is installed at the lower layer of the climbing frame. The passage frame is synchronously lifted with the climbing frame, and the tower crane operator can enter and exit the tower crane through the passage frame. The distance that the tower crane operator climbs the tower is greatly shortened. The two steel plates can respectively serve to support the tower crane operator and protect the top of the tower crane operator. The net-shaped plates on both sides can serve to protect the sides of the tower crane operator. After confirming safety, the tower crane can be boarded.

[0004] Based on the above retrieval and combining the prior art, it is found that

[0005] Although the above-mentioned retrieval patent can ensure the safety of passing, it is only applicable to ground building sites and cannot be built on the sea surface. In the face of strong winds and other adverse weather conditions on the sea surface, the structure is unstable and prone to safety accidents. In addition, it is inconvenient to disassemble, which reduces the construction efficiency, and therefore has certain limitations. UTILITY MODEL CONTENTS
