Problems solved by technology
In the elevator without machine room in the prior art, the main engine of the elevator is installed in the shaft. When people are trapped, people cannot directly turn the main engine to carry out rescue like the machine room elevator; When the weight of the counterweight is close to that of a trapped person, the car cannot move even after the brake is released, so there is a problem that rescue cannot be carried out in time

Embodiment 1
[0028] Such as Figure 1-4 As shown, the present embodiment provides an elevator balance rescue device, which mainly includes a primary transmission device and a secondary transmission device connected to each other by transmission.
[0029] The first-stage transmission device includes a running wheel arranged in the running shaft 1 of the elevator, and an operating part for controlling the rotation of the running wheel, and the operating part is arranged outside the running shaft 1 of the elevator. As a preferred solution, the rotating wheels include a driving wheel 21 and a driven wheel 22, the driving wheel 21 is arranged on the inner side wall of the elevator shaft 1, and the driven wheel 22 is arranged on the guide rail in the elevator shaft 1 11, a conveyor belt 23 is arranged between the driving wheel 21 and the driven wheel 22, and here, the transmission belt 23 can also use a conveyor chain as a transmission member between the driving wheel 21 and the driven wheel 22....

The invention discloses an elevator balance rescue device. The elevator balance rescue device comprises a first-stage transmission device and a second-stage transmission device which are in transmission connection with each other; the first-stage transmission device comprises a rotating wheel and an operation part, the rotating wheel is arranged in an elevator running shaft way, the operation partis used for controlling the rotating wheel to rotate, and the operation part is arranged outside the elevator running shaft way; the second-stage transmission device comprises a transmission rod anda gear, the transmission rod is arranged corresponding to an elevator main machine, the gear is arranged on a rotating shaft of the elevator main machine, one end of the transmission rod is hinged tothe rotating wheel, the other end of the transmission rod is provided with a sliding mechanism for enabling the transmission rod to move in a reciprocating mode along with the rotating motion of the rotating wheel, and a tooth-shaped structure which can be in meshed connection with the gear is arranged on the transmission rod. The elevator balance rescue device is used for solving the problem thatin a machine-room-free elevator product, even if the weight of an elevator car is close to the weight of a counterweight block and the situation that people are trapped by the elevator car, and alsothe rescue can be carried out conveniently.
Description
technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to an elevator balance rescue device. Background technique [0002] At present, machine-room-less elevators are developing very rapidly. With the further popularization and application of machine-room-less elevators, the demand for machine-room-less elevators in the market is also increasing. The particularity brought about by the structural characteristics has become a problem that cannot be ignored. In the elevator without machine room in the prior art, the main engine of the elevator is installed in the shaft. When people are trapped, people cannot directly turn the main engine to carry out rescue like the machine room elevator; When the weights of the counterweights are close to each other and a trapped person occurs, the car still cannot move even after the brake is released, so there is a problem that rescue cannot be implemented in time.
