Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] see figure 1 , is a structural schematic diagram of the screw elevator of the present invention. The screw elevator 1 includes an elevator car 11 , a hand brake device 13 and a transmission device 15 .

[0025] The motor cage 11 includes a side wall 111 and a mounting slot 112 disposed on the side wall 111 .

[0026] The handbrake device 13 includes a handbrake bracket 131 , a handbrake lever 132 , a locking mechanism 133 , a handbrake cable 134 , a brake 135 and a handbrake reinforcing plate 136 .

[0027] The handbrake bracket 131 is semicircular, and is fixedly embedded in the installation groove 112 and attached to the side wall 111 . The handbrake lever 132 is elongated, and the handbrake lever 132 is hinged to the handbrake bracket 131 . The locking mechanism 133 is located at one end of the handbrake lever 132 close to the handbrake br...

Abstract

The invention provides a screw elevator. The screw elevator comprises an elevator car, a transmission device and a hand brake device. The elevator car comprises a side wall and a mounting groove. The transmission device comprises a screw rod. The hand brake device comprises a hand brake support, a hand brake control lever, a locking mechanism, a hand brake pull wire and a brake. The hand brake support is embedded into the mounting groove. The hand brake support and the hand brake control lever are hinged through the locking mechanism. The brake is arranged on the screw rod in a sleeving mode. The two ends of the hand brake pull wire are connected with the hand brake control lever and the brake separately. Meanwhile, the invention provides a control method of the screw elevator. Compared with the prior art, the screw elevator is compact in structure and better in brake effect. Installation space is saved, and manual emergency braking can be realized when unpredictable emergency situations happen or a machine detection device fails.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a screw elevator and a control method thereof. Background technique [0002] With the development of the economy, the utilization rate of elevators in the service industry and residents' life is getting higher and higher, resulting in an increasing use of elevators. In order to ensure the smooth operation and service life of the elevator, the requirements for the transmission control device of the elevator are relatively high. [0003] In the prior art, the screw elevator adopts a screw transmission mode, and the transmission control device is simple and easy to control, and is more and more widely used in home elevators. The motor of the screw elevator drives the drive nut to run on the screw through the belt. In order to prevent jamming, an appropriate amount of lubricating oil can be added and regular maintenance should be carried out. [0004] But in actual use, screw elevators may...
