Description

A construction hanging basket for high-altitude operations that can move in three-dimensional space

technical field

The utility model relates to a hanging basket for high-altitude operation, which is used in the fields of construction engineering construction, curtain wall installation and the like.

Background technique

The construction gondola is a kind of non-conventional suspension equipment whose suspension mechanism is erected on a building or structure, and the hoist drives the hoisting platform to move up and down along the façade through wire ropes. It is used to carry operators, tools and materials for high-altitude operations. It has been widely used in the construction of the exterior walls of high-rise and multi-storey buildings, and the installation of curtain walls. However, when the construction site is complex and changeable, the suspension mechanism is difficult to erect, or the operating area is large, the hanging basket only moves up and down along the façade. Due to the construction requirements, the construction needs to be interrupted several times to adjust the position, which increases the safety risk during operation and reduces the construction efficiency. In addition, the conventional cantilever beam type suspension mechanism has low rigidity, and the extension length of the front beam and the rated hoisting weight are both limited. When the cantilever is long or the hoisting weight is too heavy, it cannot be used.

Utility model content

In order to solve the limitation of the working space range of conventional hanging baskets, the utility model provides a construction hanging basket for high-altitude operations that can move in three-dimensional space, so that high-altitude workers can move freely in front, back, horizontal and vertical directions, and can reach any arbitrary height in three-dimensional space. It can reduce the disassembly and handling times of the hanging basket, which not only saves the handling cost, but also reduces the safety risk during operation and improves the construction efficiency. Using the high strength and high stability of the lattice truss, the allowable pick-out length and rated lifting weight can be increased. In addition, the rational use of structural main beams instead of counterweights can solve the problem of limited counterweights on construction sites.

The technical scheme adopted by the utility model to solve its technical problems is:

The utility model relates to a hanging basket for high-altitude operation that can move in three-dimensional space, comprising a pair of lattice-type trusses and a hanging-basket translation mechanism installed on the lattice-type anchorage. A pair of lattice trusses are erected vertically on the outer wall of the building roof, and are fixed with the outer wall of the building roof through embedded parts. The translation mechanism of the gondola includes two track I-beams and three running trolleys: the first track I-beam is connected with the beam of the lattice truss cantilever section with high-strength bolts; the two ends of the track I-beam are controlled by a pair of synchronous control. The trolley realizes the track I-beam 2 moves back and forth along the track I-beam 1; the traveling trolley 2 is installed on the lower flange of the track I-beam 2, and moves back and forth along the track I-beam 2, and the traveling trolley 2 hangs a steel beam under it. , The steel beam drives the suspension platform up and down through the electric hoist, hook and wire rope.

Further, the top end of the rear support arm is welded with the lattice truss, and the bottom end of the rear support arm is connected with a sleeve bolt. The two parts are connected by welding, and the rear support arm is made of square steel pipe.

The advantages of the construction hanging basket of the utility model are: the rear support arm, the sleeve and the structural main beam are used as the counterweight part of the lattice truss, and the outer wall of the building roof is used as the front leg of the lattice truss, instead of the counterweight to balance Lifting weight, the sleeve is fixed on the concrete main beam through the second embedded part, and the second embedded part meets the pullout resistance requirement through calculation; The sleeve is welded on the embedded part 2, and can be cut off directly after the dismantling of the construction gondola.

The use of lattice trusses in the suspension mechanism is beneficial to increase the rigidity, ensure lateral stability, and greatly increase the allowable pick-out length and rated hoisting weight. The track I-beam one is used as the running track of the track I-beam two. The track I-beam 2 is used as the translation track of the traveling trolley 2. The steel beam under the traveling trolley 2 controls the up and down operation of the suspension platform through the electric hoist, hook and wire rope to realize vertical movement, and the operator can reach the outer wall of the building roof. Construction operations can be carried out at any location. Reduce the disassembly and handling times of the hanging basket, save the handling cost and handling time.
