Description

Suspended tower crane driver safety telescopic channel

technical field

The invention relates to a safety telescopic channel for a suspended tower crane driver.

Background technique

At present, most of the houses are high-rise buildings, and the tower cranes are installed and used at a relatively high height. Tower crane operators usually use artificial passages to get up to the tower crane from the main body of the built building to the roof of the building, so as to save energy and avoid falling accidents caused by climbing the tower crane for a long time. At present, the safety passages of tower crane operators are mostly erected by steel pipes. One end is placed on the main body of the building, and the other end is placed on the standard section of the tower crane. There are handrails above the passage, steel plates are laid, and vertical nets are placed on the side.

However, the channel disadvantages of the existing channel are: 1. It takes a long time to set up the channel. It takes two people and half a day to build a channel; 2. There is a risk of falling from a high place when the erection personnel are working at heights, and objects such as steel pipe deductions will hit the ground personnel; 3. As the construction progress progresses, the height of the tower crane increases. The channel has been set up many times; it is extremely inconvenient and costs a lot of labor costs; 4. One end of the old-fashioned tower crane channel is placed on the standard section chord, and the shaking of the tower crane causes friction damage to the standard section chord by the channel, which poses a great safety hazard; 5. The construction of the channel occupies the turnover materials of the project, which causes additional cost increase; 6. After the construction is completed, when the channel is dismantled, it is extremely inconvenient for professionals to dismantle the channel before dismantling the tower crane.

The utility model patent with the application number CN202221895273.3 belongs to the technical field of building construction, and discloses a safety passage for tower cranes, which includes a support beam group and a passage main body. A wall connecting piece is connected between the tower crane and the high-rise building, and the supporting beam set includes at least two supporting beams, and each supporting beam is configured to be arranged on the connecting wall piece at intervals. The channel main body includes a support platform, a first guardrail and a second guardrail. The first guardrail and the second guardrail are relatively erected on the support platform in the width direction of the support platform. The support platforms are arranged on each support beam. One end of the tower extends to the opening of the high-rise building, and the other end is fixed to the tower crane. The driver of the tower crane climbs to the position of the hole in the high-rise building, and then reaches the height of the tower crane from the hole through the support platform. However, the safety channels described in the above patents still have problems in the prior art, and no technical means to solve the above problems have been proposed.
