Embodiment 1

[0040] Embodiment one: if Figure 7 Shown, a kind of safety elevator comprises hoistway wall 8, car 2, counterweight 5, and car 2 runs in hoistway wall 8, and hoistway wall 8 of the present embodiment is wall body or civil engineering structure, and car 2 adopts In the traction and drag mode of the existing elevator, the car 2 is connected with the counterweight 5 by the traction sheave 112 and the guide wheel 121 with a wire rope 254 .

[0041] Such as Figure 13 As shown, the elevator described in this embodiment includes a hoistway wall 8, a car frame 21 and a car guide rail located on the hoistway wall 8. The described guide rail is not a common T-shaped guide rail, but a rack guide rail 110. The rack guide rail 110 is symmetrically arranged on the left and right and is fixed on the inner side of the hoistway wall 8 through the guide rail bracket 111. The front side or the rear side of the rack guide rail 110 is provided with a rack, and the bottom of the car frame 21 is ...

Embodiment 2

[0046] Embodiment two: if Figure 12 As shown, this embodiment is basically the same as Embodiment 1, the difference is that the hoistway wall 8 is improved. The hoistway wall 8 of this embodiment adopts a metal frame hybrid structure, and the hoistway wall 8 includes a well tower and a bottom pit body 13. The well tower is composed of more than two derricks according to the number of floors where the elevator is installed. 1. It is assembled by lamination of high-strength bolts. The derrick at the bottom of the well tower is called the bottom derrick, and the bottom derrick is horizontally fixed on the pit body 13 by high-strength bolts.

[0047] Such as figure 1 As shown, the derrick 1 includes 4 columns 101, 3 rear beams 104 and 3 left and right side beams 105 respectively. A connecting seat 107 is provided, and the connecting seat 107 is provided with 4 connecting holes 108 (in other embodiments, the connecting holes 108 may also be 3 or more); Then, a brace 106 is prov...

Abstract

The invention discloses a safety elevator, and relates to lifting equipment. The elevator comprises a hoistway wall (8), a cage frame (21) and cage guide rails, wherein the cage guide rails are rack guide rails (110); the bottom part of the cage frame (21) is provided with a main shaft (34); the middle part of the main shaft (34) is provided with a cage braking device (37); the two ends of the main shaft (34) are provided with gears (35) which are in rack meshing with the rack guide rails (110); the gears and racks are adopted between a cage and the hoistway wall (8) for meshing connection, so that the cage braking device (37) arranged on the main shaft (34) of the cage can realize effective control for the operation of the cage, further the safety in operation of the cage is improved, a safety device of the elevator also can be simplified, and the cost of the elevator can be reduced. In the safety elevator, the structure is simple, the working is reliable, the operation safety of the cage is high, and the cage can be used on all passenger and goods elevators, and also the existing elevator can be modified.

Description

technical field [0001] The invention and creation title of the prior application of the present invention is "a hydraulic speed-limited elevator", the application number is ZL201110000728.0, and the application date is January 4, 2011. [0002] The present invention relates to a hoisting device, in particular to an elevator. Background technique [0003] Although the traction technology of the existing elevator is very mature, the biggest defect of the traction drive is that the guide rail and the guide shoe are slidingly connected, the brake is installed on the traction machine, and the steel wire rope for the car passes through the traction sheave and the counterweight on the traction machine. The connection between the traction sheave and the wire rope is a friction transmission, and the reliability of the friction transmission is poor. Once the electronic control system fails or the wire rope and the traction sheave slip or even breaks, the brake will fail and cause the ...
