Embodiment Construction

[0009] A detailed description will be given below with reference to the drawings and implementation examples.

[0010] Such as figure 1 As shown, in the present invention, the motor drives the screw rod I to rotate through the belt, and drives the screw rod II to rotate by driving the reversing gear. The screw rod I and the screw rod II rotate and mesh with the wire sleeve on the car body to lift the car body. The screw rod is fixed up and down by bearings, the upper part of the car body is connected with the cable, and the cable is connected with the counterweight through the pulley. When the car body rises, the motor drives the screw rod to rotate in the direction of the car body. Under the condition that the screw rod and the screw sleeve are engaged, the car body climbs up along the screw rod. At the same time, the car body reduces the screw rod engagement under the traction of the counterweight. The lifting power can save power consumption. When the elevator breaks down, be...

Abstract

Disclosed is a lead screw engaged elevator. The lead screw engaged elevator is characterized in that the elevator is provided with a motor (1); the motor drives a lead screw I to rotate through a belt (2) and drives a reversing gear (3) so as to drive a lead screw II to rotate; the lead screw I and the lead screw II are engaged with threaded sleeves (5) on a car body (4) through rotation so as to lift the car body; the lead screws are fixed up and down through bearings (6); the upper portion of the car body is connected with a cable rope (7); the cable rope is connected with a balance weight (9) through a pulley (8). According to the lead screw engaged elevator, the lead screws and the threaded sleeves are engaged so that the car body can be controlled to lift, and the phenomenon that common elevators suddenly fall down due to breaking of cable ropes can be avoided.

Description

Technical field [0001] The invention relates to a new type of elevator, which is suitable for transporting people and goods and belongs to the field of elevator safety. Background technique [0002] The elevator is convenient for high-rise residents to get on and off, but it often becomes a killer. The key to why an elevator becomes an invisible killer lies in the quality of the elevator itself and the maintenance of the property. At present, the elevators used by high-rise residents are relatively safe in terms of design. These elevators use wire ropes to lift and lower the elevator car body. Although the strength of these wire ropes is configured to bear the car and the rated load, the traction force is also considered. ; The elevator also has a set of anti-falling system, so the design can completely prevent the elevator from falling. In fact, accidents of elevator falling often occur due to two reasons. One is that the quality of the elevator itself does not meet the design...
