Semi-automatic precast stair turning-over machine

Abstract

The invention discloses a semi-automatic precast stair turning-over machine. The semi-automatic precast stair turning-over machine comprises a base support, a rotating shaft, a turning-over frame, a driving motor, a chain, and an electric control box, wherein the base support is of a triangular frame structure, the rotating shaft is arranged in a groove of an uppermost triangle vertex of the basesupport, the turning-over frame is fixed above the rotating shaft, two vertical supporting columns are arranged on one side of the base support, one side of the turning-over frame is arranged on the supporting columns, limiting columns are arranged on the other side of the turning-over frame, the distance from one side of the turning-over frame to the rotating shaft is greater than the distance from the other side of the turning-over frame to the rotating shaft, the driving motor is arranged in the base support, the driving motor is connected with a speed reducer, the speed reducer is connected to one end of the rotating shaft through the chain, and the driving motor is connected with the electric control box. The semi-automatic precast stair turning-over machine has the advantages that the structure is simple, a stair can be quickly turned over, the precast stair production and the turning-over efficiency are improved, the energy consumption is low, and the secured, standardized and normalized construction is facilitated.

Description

technical field [0001] The invention belongs to the technical field of building profile processing equipment, and in particular relates to a semi-automatic prefabricated staircase turning machine. Background technique [0002] Now in the fields of construction, transportation, water conservancy and other fields, concrete prefabricated parts are widely used, and the varieties include: prefabricated reinforced concrete laminated floors, wall panels, stairs, balconies, pipe galleries, air-conditioning panels and walls and other architectural prefabricated products, among which the production of stairs has been completed Finally, it is necessary to turn the vertical staircase to the flat system, which is convenient for the later lifting, transportation and installation of the stairs. The previous turning method is to use two cranes to lift and control the turning at the same time. The work efficiency is relatively low, and there is a great safety during the turning process Hidde...

[0002] Now in the fields of construction, transportation, water conservancy and other fields, concrete prefabricated parts are widely used, and the varieties include: prefabricated reinforced concrete laminated floors, wall panels, stairs, balconies, pipe galleries, air-conditioning panels and walls and other architectural prefabricated products, among which the production of stairs has been completed Finally, it is necessary to turn the vertical staircase to the flat system, which is convenient for the later lifting, transportation and installation of the stairs. The previous turning method is to use two cranes to lift and control the turning at the same time. The work efficiency is relatively low, and there is a great safety during the turning process Hidden dangers are also easy to bump into the corners; another method is to use a crane to hoist the prefabricated stairs on the open sandy ground and push them to turn over. This method not only has low turning efficiency, but also increases the cost of turning the stairs, and there are also potential safety hazards
