Embodiment 1

[0033] Embodiment one: if Figure 6 As shown, the elevator described in the present embodiment comprises a hoistway wall 8, a car 2, and a counterweight 5. The car 2 runs in the hoistway wall 8, and the car 2 uses a wire rope 254 to pass through the traction sheave 112 and the guide pulley 121 and the counterweight 5. Heavy 5 connected.

[0034] This embodiment adopts the traction and drag mode of the existing elevator. The structure of each part of the elevator is the same as that of the existing traction elevator. The difference is that a main shaft 34 is installed on the car, and a car brake is added on the main shaft 34. 37. In order to ensure that the car brake 37 can work effectively, the sliding connection between the hoistway wall 8 and the car 2 is changed to a rack and gear meshing connection.

[0035] Such as Figure 12Shown, a kind of car is provided with the safety elevator of brake, comprises hoistway wall 8, car frame 21 and the car guide rail 110 that is loca...

Embodiment 2

[0040] Embodiment 2: This embodiment is basically the same as Embodiment 1, the difference is that the hoistway wall 8 is improved, and the hoistway wall 8 of this embodiment adopts a metal frame hybrid structure. Such as Figure 7 As shown, the hoistway wall 8 of this embodiment includes a well tower and a pit body 13. The well tower is assembled by laminating two or more steel structure derricks 1 through high-strength bolts according to the number of floors where the elevator is installed. Formed, the derrick at the bottom of the well tower is called the bottom derrick, and the bottom derrick is horizontally fixed on the bottom pit body 13 by high-strength bolts.

[0041] 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 connection seat 107 is provided, and four connection holes 108 are arranged on the connection seat 107 (in other embodiments, the number of connection holes 108 may also b...

Abstract

The invention discloses a safe elevator with a brake in a lift car, relating to hoisting equipment. The elevator comprises a hoistway wall (8), a lift car frame (21) and a lift car guide rail (110), wherein the left side and the right side of the hoistway wall (8) at the front side or the rear side of the lift car guide rail (110) are respectively symmetrically provided with racks (36); the lift car frame (21) is provided with a main shaft (34); a lift car brake (37) is arranged at the middle part of the main shaft (34); gears (35) are arranged at two ends of the main shaft (34); and the gears (35) are meshed with the racks (36). The lift car is meshed and connected with the hoistway wall (8) through the gears and the racks so that the lift car brake (37) arranged in the lift car can effectively control the operation of the lift car, which is beneficial to improving the safety of the operation of the lift car, simplifying a safety device of the elevator, and reducing the cost of the elevator. The safe elevator is simple in structure, reliable in work and high in operation safety of the lift car, can be used on all passenger elevators and goods elevators and can be obtained throughchanging the traditional elevator.

Description

technical field [0001] The invention-creation title of the prior application of the present invention is "an elevator assembled with a combined derrick", the application number is ZL201110000730.8, 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 cau...
