According to one aspect of the present disclosure, a hoistway-type traction elevator for construction is provided. Fig. 1 schematically shows a schematic structural view of an elevator 100a according to a first embodiment of the present disclosure.
Referring to fig. 1, an elevator 100a includes a traction machine 1, a top beam 2, a traction medium 3, a cage 5 and a counterweight 6;

the other end of the traction medium 3 is led out from the traction machine 1 and then led to a counterweight 6 positioned below the traction machine 1 and is connected with the counterweight 6;
the traction medium 3 is a steel wire rope or a steel belt, and the top beam 2 can move up and down.
The elevator 100a of the present embodiment is installed in a building hoistway 7, such as an elevator hoistway, under construction. The top beam 2 is transversely arranged at the top of the well, and two ends of the top beam 2 can be fixed on the wall of the building well 7. When the construction of a certain floor is completed, the installation position of the girder 2 is raised by one floor and the working length of the traction medium 3 is extended to increase the maximum liftable height of the lifter 100 a. In the embodiment, the traction machine 1 is adopted to drive the steel wire rope or the steel belt suspension cage 5 to lift, and compared with a gear rack lifting mode, the lifting device has the advantages of high lifting speed and low noise. In order to keep the suspension cage 5 stable, a guide rail is arranged on the wall of the building well 7, and the suspension cage 5 is in sliding fit with the guide rail so as to avoid the suspension cage 5 from shaking. The elevator 100a of the present embodiment has an advantage of saving a hoisting medium by adopting a top-mounted type structure of the hoisting machine 1. Two sections of traction media 3 led out by the traction machine 1 are directly connected with the suspension cage 5 and the counterweight 6, the traction ratio is 1:1, and the elevator has the advantage of high lifting speed under the condition that the rotating speed of the traction machine is the same. The traction medium 3 is a steel wire rope or a steel belt. The steel wire rope is relatively more convenient to manufacture, but the steel belt is also flat in design, so that the contact area is increased, and the traction friction force is improved; meanwhile, the steel belt does not need additional lubrication, is free of oil stain pollution, is lower in vibration amplitude than a steel wire rope, is more stable and comfortable, saves electric energy, and is long in service life and has advantages.

When the diameter of the traction sheave of the traction machine 1 is smaller than half the width of the cage 5, the interval between the traction media 3 drawn from the traction machine 1 at both ends is small, which causes the cage 5 and the counterweight 6 to interfere with each other. The guide wheel 4 adjusts the distance between two sections of traction media 3 led out from the traction machine 1, so that the traction media 3 at two ends have enough distance for the suspension cage 5 and the counterweight 6 to freely move up and down, and the interference between the suspension cage 5 and the counterweight 6 is prevented.
Alternatively, the guide pulley 4 of the elevator 100a is disposed below the traction machine 1 and biased to the cage 5 side. The guide wheels 4 of the embodiment suitably deviate the hoisting medium 3 leading to the cage 5 from the hoisting medium 3 leading to the counterweight 6 to increase the distance between the two sections of hoisting medium 3.
Alternatively, the free end of the hoisting medium 3 is connected directly to the cage 5, for example by means of a conventional wire rope clamp. When the construction of a certain floor is finished and a higher floor needs to be constructed, the mounting position of the top beam 2 is moved upwards, and then the longer traction medium 3 is replaced, so that the maximum liftable height of the cage 5 is lifted.
Alternatively, the hoisting medium 3 is connected to the cage 5 in a centrally fixed manner. In the embodiment, the traction medium 3 is connected with the suspension cage 5 in a fixed manner at the middle part, that is, a sufficient length of the traction medium 3 is reserved at one end of the traction medium 3, for example, the reserved traction medium 3 can be coiled and placed on the top of the suspension cage 5. According to the increase of the floor height, the top beam 2 is lifted to a certain height, and the reserved dragging medium 3 with a certain length is correspondingly released so as to prolong the working length of the dragging medium 3 without replacing the new dragging medium 3 or adopting a mode of continuously wiring and prolonging.

The wedge housing 12 receives the weight of the cage 5, the wedge 13 receives the pulling force of the traction medium 3, and the two directions are opposite, so the traction medium 3 around the periphery of the wedge 13 is pressed between the inner wall of the inner cavity 14 and the wedge 13, and the heavier the cage 5, the tighter the traction medium 3 is pressed. The cross-sectional dimension of the cavity 14 tapers from the large mouth end 18 to the small mouth end 19, making the cavity 14 wedge-shaped. The cross-sectional dimension of the wedge 13 gradually decreases from the large end 15 to the small end 16, so that the wedge 13 is wedge-shaped. The width of the wedge 13 is larger than the width of the small opening end 19 of the inner cavity 14 after the rope is wound on the outer periphery of the wedge 13, so that the wedge 13 and the traction medium 3 are limited by the wedge inner wall of the inner cavity 14 and cannot fall off from the small opening end 19, and the wedge sleeve 12, the wedge 13 and the traction medium 3 are locked with each other. When the force applied to the wedge sleeve 12 is removed, the wedge 13 can be removed from the wedge sleeve 12 and the hoisting medium 3 can be detached from the connecting element 30. The connecting piece 30 of the embodiment has the advantages that the rope can be connected from any position in the middle of the traction medium 3 without cutting off the rope, and the connecting position of the connecting piece 30 on the traction medium 3 can be randomly adjusted according to the requirement, so that the working length of the traction medium 3 is released; the second has the self-locking characteristic; and thirdly, the connection is quick.
