Problems solved by technology

[0004] Reduce the tension difference between the tension T1 on the wire rope car side and the tension T2 on the counterweight side, that is, choose a reasonable balance rope (balance chain) device to balance the tension difference caused by the length change of the wire rope during the elevator operation. The original balance rope (balance chain) device is impeccable, and the weight of the car is increased appropriately to reduce the ratio of T1 / T2. The effect is not obvious, and the cost of the elevator is increased, and the load of the machine room is increased.
[0005] And this existing elevator has a biggest shortcoming, promptly can't run when power failure, even when sudden power failure, elevator promptly can hover in mid-air, and personnel not only can't reach destination floor, is extremely inconvenient, and may also Trapped in an elevator because it was suspended in mid-air

Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the present invention provides a kind of trim type elevator, and it comprises a car 1, a fixed pulley 2 fixed on the top of the elevator shaft, a trim box 3, a belt pulley 4, a weight chain 5, a storage battery (not shown in the figure) out) and a control system (not shown).

[0014] Wherein, the car 1 is no different from the car of an ordinary elevator, and provides a space for accommodating people and goods, which will not be described in detail here.

[0015] The fixed pulley 2 is composed of a traction sheave 21 and two secondary wheels 22, 23, wherein the traction sheave 21 is located in the middle, and a wire rope 6 is wound on it, and the two secondary wheels 22, 23 are located in the traction sheave. The two outsides of 21, and the inboard of two secondary wheels are equipped with clutch brake pads, respectively form a clutch between two secondary wheels and the traction sheave.

[0016] The balance box 3 is connected...

Abstract

A counterweight balanced elevator without motor is composed of a cage, a static pulley with two clutches and fixed to the top of cage well, a counterweight balancing box communicated with water source, a belt wheel, a weighting chain wound on a chain wheel with a detent, an electric accumulator set, and a control system consisting of direction control module, weight comparison module, counterweight balancing module, and starting, accelerating or decelerating and braking module.

Description

【Technical field】 [0001] The invention relates to an elevator, in particular to a trim type elevator. 【Background technique】 [0002] The current elevators all use the traction hoisting mechanism to lift the elevator car. The wire rope of the existing traction machine is suspended on the traction sheave, one end of which is connected to the car, and the other end is connected to the counterweight (balance weight). When the elevator rotates according to the traction sheave, the friction between the wire rope and the traction sheave overcomes the tension difference between the traction wire rope on the car side and the counterweight side at any position to ensure that the elevator follows the normal rotation and reverse rotation of the traction sheave. Instead, keep running up and down. Therefore, to improve the traction capacity of the elevator, only increase the friction between the wire rope and the traction sheave and reduce the tension difference between the car side and...
