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 traction machine underneath type construction elevator applicable to a building hoistway 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 transversely arranged at the upper end of a building well 11, the traction machine 1 is arranged at the bottom of the well 11, and a rewinding wheel 9 is arranged above the traction machine; the top of the suspension cage 4 is provided with a first pulley 6; the upper end of the top beam 2 is provided with a second pulley 7 and a third pulley 8 at intervals; one end of the traction medium 3 is led out upwards from the traction machine 1, and is led out upwards and fixed after winding around the second pulley 7 and the first pulley 6; the other end of the dragging medium 3 is led out upwards from the tractor 1, bypasses the rewinding wheel 9 and the third pulley 8, then is led out downwards to the fourth pulley 12, and the dragging medium 3 is led out upwards and fixed after bypassing the fourth pulley 12.

Compared with the traditional elevator which is installed outdoors, the elevator shaft lifting device is installed in a building shaft 11, such as an elevator shaft, so that the safety is improved; the two ends of the top beam 2 are fixed on the wall of the building shaft 11, and the mounting position of the top beam 2 is lifted after the construction of a certain floor is finished, 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 11, and the suspension cage 4 is in sliding fit with the guide rails, so that the suspension cage 4 is prevented from shaking. The building shaft 11 is provided with a door at each floor, and the cage 4 is lifted and lowered against the side of the building shaft 11 having the door.

The second pulley 7 is arranged close to the suspension cage 4, and the third pulley 8 is arranged close to the counterweight 5 so as to adjust the distance between two sections of traction media 3 led out from the traction machine 1, so that the traction media 3 at the two ends have enough distance for the suspension cage 4 and the counterweight 5 to freely move up and down, and the interference between the suspension cage 4 and the counterweight 5 is prevented; the compound winding wheel 9 saves more labor when the traction machine 1 lifts and lowers the cage 4.

After the traction medium 3 led out from the fourth pulley 9 is led upwards, the rope head is fixed through the rope head fixing device, redundant steel wire ropes form a reserved section 10, the reserved section 10 is arranged on the top beam 2 after being coiled, and when the maximum liftable height needs to be increased, the reserved section 10 with a certain length can be released to prolong the working length of the traction medium 3.

In the 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 in order 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 12 may be arranged at the top of the counterweight 5 in a similar multi-angle manner.

compared with the traditional elevator arranged on the outer wall of a high-rise building, the elevator of the embodiment is arranged in the hoistway of the building, so that the safety is higher; the traction machine is used for driving the steel wire rope or the steel belt suspension cage to lift, so that the lifting device has the advantages of high lifting speed and low noise; the elevator of the embodiment adopts a traction machine underlying structure, has the characteristic of flexible arrangement of the traction machine, can plan the largest suspension cage in the existing hoistway, fully utilizes the space of the hoistway, and greatly increases the convenience of maintenance of the traction machine.
