Tower crane moving passage system

Abstract

The invention discloses a tower crane moving passage system. The system comprises a lifting frame, a lifting device, a telescopic platform and a telescopic device, wherein the lifting frame encloses the outer side of a standard section of a tower crane in an unseparated mode, the lifting frame is provided with a guide wheel which can only ascend and descend along the standard section of the towercrane and an ejector rod used for locking the height of the lifting frame, a power mechanism of the lifting device is installed on a tower crane balance arm and drives the lifting frame to ascend anddescend through a steel wire rope, the telescopic platform comprises a fixed platform and a movable platform, the fixed platform is connected with one side, facing a building structure, of the liftingframe in a swinging and locking mode, the movable platform is arranged on the fixed platform in an unseparated mode and can slide outwards along the fixed platform to the building structure, the telescopic device is used for driving the movable platform to stretch along the fixed platform, one end, close to the building structure, of the movable platform is provided with a screw rod capable of adjusting the height, and the screw rod is supported on the building structure during use. The system can rise along with the jacking of the tower crane and the installation of a wall attaching rod piece, can be fixed at any position of the tower crane standard section, and can adjust the setting angle and length.

Description

technical field [0001] The invention belongs to the field of building construction equipment, and in particular relates to a tower crane movable aisle system. Background technique [0002] The height of the tower crane increases many times with the height of the building under construction. Therefore, the tower crane driver needs to enter the operation room many times during the use of the tower crane. The current solution is to first build the tower crane aisle on the floor closer to the operation room, and then The tower crane driver enters the interior of the tower crane through the tower crane aisle, and finally climbs the ladder from the interior of the tower crane to enter the operation room. [0003] At present, the tower crane aisle is made of section steel or construction steel pipe according to the actual distance, and there are the following problems: 1) When installing the tower crane wall-attached rod, it is necessary to lift the tower crane aisle first, and wai...

AI Technical Summary

Problems solved by technology

[0003] At present, the tower crane aisle is made of section steel or construction steel pipe according to the actual distance, and there are the following problems: 1) When installing the tower crane wall-attached rod, it is necessary to lift the tower crane aisle first, and wait for the wall-attached rod to be installed. If it is hoisted on the wall-attached rods, or the tower crane aisle does not move, after installing the wall-attached rods, the tower crane aisle will be re-built. Therefore, not only will there be a greater safety hazard, but the tower crane will be raised many times, and it will need to be dismantled and erected many times. 2) The distance between the building and the tower crane varies with the construction site, and the angle and length of the aisle are different. It is necessary to make different specifications of the tower crane aisle according to the actual situation of each project, which cannot be reused and wastes resources.
