Abstract

The invention relates to a bearing beam self-elevating type hoistway construction elevator. The construction elevator comprises a bearing beam, a traction machine, a steel wire rope, a counterweight and a cage, wherein the bearing beam comprises a beam body, the beam body is erected on an embedded supporting piece, the beam body comprises a main body part and a folding part, a limiting structure is arranged between the folding part and the main body part, the bearing beam is provided with a lifting mechanism, the traction machine is detachably mounted in a door opening, a first guide wheel anda second guide wheel are rotationally arranged on the main body part, counterweight fixing ends and cage fixing ends are arranged on the main body part in a left-right spaced mode, one end of the steel wire rope is fixed to the counterweight fixing ends and sequentially winds around a counterweight movable pulley, a first guide wheel, a traction wheel, a second guide wheel and a cage movable pulley, then the steel wire rope is fixed to the cage fixing ends, and the remaining rope is placed in any floor. The construction elevator is advantaged in that the operation self-weight of the construction elevator is reduced, electric energy is saved, the gravity borne by the bearing beam is reduced, and the structure is simpler.

Description

technical field [0001] The invention relates to the technical field of construction lifting, in particular to a load-bearing beam self-elevating hoistway construction elevator. Background technique [0002] In the construction of high-rise buildings, the construction price raising machine for elevator shafts is usually set on the ground by traction machine, and the suspension ratio is 1:1. This setting has many disadvantages: one is large in size and heavy in weight, and the other is high in power and energy consumption. The third is that the steel wire ropes used for subsequent heightening need to be placed on the top of the cage, so that the elevator needs to carry more steel wire ropes when it is working, which brings excessive power consumption to the elevator and also buryes safety hazards. The steel wire rope to be used for subsequent heightening is on the top of the cage, blocking the safety escape window on the top of the cage. Directing the wire rope to the cage an...
