Description

Combined lifting appliance for installing prefabricated elevator in elevator lane

Technical Field

The utility model relates to the technical field of assembly type building hoisting, in particular to a combined lifting appliance for installing an elevator prefabricated assembly type stairway.

Background

With the aggravation of the aging population, a significant part of the elderly people in China still live in the multi-storey houses without elevators, which affects the quality of life of the elderly people to a certain extent. With the advance of the barrier-free urban work, the practical requirement of adding elevators to multi-layer houses in each city becomes an increasingly prominent problem.

In the old district elevator transformation project, the elevator additionally installed in the old building is required to face the problem of entering a house, and some buildings are not suitable for the elevator to directly reach a user gate, but a reinforced concrete corridor or a reinforced concrete corridor is required to be additionally installed, so that the transformation requirement can be met. In the old district elevator transformation project, generally adopt assembled stair in order to satisfy elevator income family demand, assembled stair is generally prefabricated in the mill, adopts the mode of hoist and mount assembly to accomplish the installation after transporting to scene, and this in-process, the use of hoist is indispensable.

For example, chinese issued patent number CN209583387U, an adjustable spreader for assembled stairway lifting: comprises a cross beam, a support rod, a sling and an iron shoulder pole; the cross beam comprises a first cross beam and a second cross beam; a plurality of perforations are respectively arranged on the first cross beam and the second cross beam along the horizontal direction; the perforations on the first cross beam correspond to the perforations on the second cross beam respectively, so that the support rod can pass through the perforations to form a hoisting support structure; the support rods comprise a first support rod and a second support rod; the first support rod passes through the perforations on the left sides of the first cross beam and the second cross beam to form a left side hoisting support structure; the second supporting rod passes through the first cross beam and the through holes on the right side of the second cross beam to form a right side hoisting supporting structure; one end of the sling is connected with the left hoisting supporting structure and the right hoisting supporting structure, and the other end of the sling is connected with the iron shoulder pole; by adopting the scheme, the hoisting size can be conveniently adjusted, the stress state of the hoisting ring and the member is improved, and the installation of the prefabricated staircase is more accurate.

However, most of the hoisting prefabricated stair slings at present directly adopt sling connecting components and electric winches, because the weight of the prefabricated stair is large, the pressure generated by the sling is large, the sling directly penetrates through the bearing hanging ring in a slender manner, the pressure born by the sling is extremely large, when the sling starts to lift the prefabricated stair and moves the prefabricated stair, the sling and the hanging ring slide, because the pressure between the sling and the hanging ring is large, a great amount of heat is generated by friction force, mechanical structural damage is easily generated to the sling and the hanging ring, the sling is used in high strength during construction, hidden damage of the sling and the hanging ring is not easy to perceive, and accidents are easy to occur; meanwhile, prefabricated stairways generated by additionally installing elevators in old communities are installed in a building in general construction operation, and a common crane cannot extend a suspension arm into the building for operation. Therefore, the existing requirements are not met, and for this reason we propose a combined sling for installing prefabricated assembled stairway of an elevator.
