Construction elevator

Abstract

The invention discloses a construction elevator, and relates to the technical field of construction elevator devices. The elevator comprises a shear-type elevator, a placing plate is arranged at the upper end of the shear-type elevator, two symmetrical side protection units are arranged at the upper end of the placing plate, each side protection unit comprises a plurality of positioning plates stacked in the vertical direction, the adjacent positioning plates are hinged, the positioning plate located at the upper portion can be turned outwards relative to the positioning plate located at the lower portion, a first groove is formed at the upper end of any positioning plate, an elastic supporting assembly is arranged in the first groove, a second groove is formed at the lower end of each positioning plate, an elastic pressing assembly is arranged in each second groove, and the side protection units are provided with locking units used for limiting overturning of the positioning plates. Multiple pipes with different diameters can be lifted at the same time, the stability of the pipes in the lifting process is guaranteed, and the situation that the pipes slip is avoided; and constructors can conveniently take down the pipes from the elevator.

Description

technical field [0001] The invention relates to the technical field of construction hoist devices, in particular to a construction hoist. Background technique [0002] At present, in the building construction process, it is often necessary to use a hoist to lift and transport the pipe or cylindrical profile, so that the pipe or cylindrical profile reaches a certain height, which is convenient for construction personnel to install and use. In the prior art, a placement plate is usually arranged on the upper end of the hoist, and then a plurality of arc-shaped grooves are arranged side by side on the placement plate. When the pipe is lifted, the pipe is placed in the groove and passed through the groove. It acts as a limit for the pipe to prevent the pipe from slipping off the hoist. [0003] However, with the above technology, only pipes with a specified diameter can be lifted. When the diameter is too large, the groove cannot play a limiting role. When the diameter is too s...

AI Technical Summary

Problems solved by technology

[0003] However, with the above technology, only pipes with a specified diameter can be lifted. When the diameter is too large, the groove cannot play a limiting role. When the diameter is too small, the pipe shakes freely in the groove, and rigidity occurs with the inner wall of the groove. Collision, easy to cause damage to the outer wall of the pipe, and there is a risk of the pipe slipping out of the groove

At the same time, the number of pipes to be transported at one time is limited by the area of ​​the placement plate, and the pipes can only be laid in the groove. If multiple pipes are stacked, there is a safety hazard of pipe slippage

And the pipe is located in the groove. When the construction personnel need to remove the pipe from the placement plate, the area of ​​effort is small, and it is inconvenient for the construction personnel to remove the pipe.
