Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments; all other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, the shaft elevator for building construction with a rear-mounted traction machine according to the present invention includes a traction machine 1, a top beam 2, a traction medium 3, a cage 4, and a counterweight 5; the top beam 2 is fixed at the upper end of a building well 12, and the traction machine 1 is arranged outside the well 12; the top of the cage 4 is provided with a first pulley 6, and the counterweight 5 is provided with a seventh pulley 12; a second pulley 8 and a third pulley 9 are arranged on the top beam 2, wherein the second pulley 8 is arranged close to the suspension cage 4, and the third pulley 9 is arranged close to the counterweight 5; the bottom of the well 12 is provided with a compound winding wheel 7; one end of the traction medium 3 is led out from the traction machine 1, and is wound by the compound winding wheel 7, the second pulley 8 and the first pulley 6 and then is led upwards and fixed; the other end of the traction medium 3 is led out from the traction machine 1, wound by the compound winding wheel 7, the third pulley 9 and the fourth pulley 10, and then led upwards and fixed.

The present invention is installed in a building hoistway 12, such as an elevator hoistway, and improves safety compared to conventional outdoor-mounted elevators; the two ends of the top beam 2 are fixed on the wall of the well 12 of the building, and after the construction of a certain floor is completed, the mounting position of the top beam 2 is lifted, and the working length of the traction medium 3 is prolonged, so that the maximum lifting height of the lifter is increased. The elevator of the embodiment of the disclosure adopts the traction machine 1 to drive the steel wire rope or the steel belt suspension cage 4 to lift, and compared with the traditional gear rack lifting mode, the elevator has the advantages of high lifting speed and low noise. In order to keep the suspension cage 4 stable, vertical guide rails are arranged on the wall of the building hoistway 12, and the suspension cage 4 is in sliding fit with the guide rails so as to avoid the suspension cage 4 from shaking. The building shaft 12 is provided with a door at each floor, and the cage 4 is lifted and lowered against the side of the building shaft 12 having the door.

The first pulley 6, the second pulley 8, the second pulley 9 and the second pulley 7 play roles of reversing and guiding the movement of the traction medium 3; after the traction medium 3 led out by the fourth pulley 10 is led upwards, the rope end is fixed by the rope end fixing device, the redundant steel wire rope forms a reserved section 11, the reserved section 11 is coiled and then arranged on the top beam 2, and when the maximum liftable height needs to be increased, the reserved section 11 with a certain length can be released to prolong the working length of the traction medium 3.

In a specific implementation of the present invention, the placing angle of the top beam 2 on the top of the building hoistway 11 is multi-angle, so to match the multi-working condition top beam 2 angle placement, in some embodiments, the first pulley 6 may be arranged at the top of the suspension cage 4 in multi-angle, for example, one side surface of the first pulley 6 and the front side surface of the suspension cage 4 are arranged at an angle of 0 °, 30 °, 60 ° or 90 °, and similarly, the fourth pulley 10 may be arranged at the top of the counterweight 5 in a similar multi-angle manner.
