Problems solved by technology

However, in the above scheme, the movement of the motor will generate vibration and noise, which cannot be isolated from the car, and the comfort during operation is not good
Since the motor is installed on the car frame, if the elevator fails and causes the elevator to stop, it will be difficult to rescue and the maintenance of the motor will be troublesome.

Embodiment 1

[0028] The rack and pinion elevator in this embodiment includes a transmission assembly and a carrier, the transmission assembly drives the carrier to move, and the carrier can be a car or a platform.

[0029] Such as figure 1 and 3 As shown, the transmission assembly includes a gear set A, a gear set B and a driving member 1 installed and fixed in the hoistway. The carrier is provided with a rack a and a rack b for meshing with the gear set A and the gear set B. The rack a and rack b are racks with tooth patterns on one side, the length of rack a and rack b is adapted to the height of the carrier, so that the length of rack a and rack b is less than or equal to the height of the carrier, The rack a and the rack b are bolted and fixed to the carrier body by opening through holes.

[0030] Among them, the gear set A includes a plurality of transmission gears A-1 arranged in sequence along the vertical direction of the hoistway, and a reversing gear A-2 is arranged between adj...

Embodiment 2

[0034] The rack and pinion elevator of this embodiment differs from Embodiment 1 in that:

[0035] Such as Figure 4 As shown, the reversing gear 2-1 can be selected from the same gear as the transmission gear model, and the meshing angle can be selected properly, and the meshing position can be installed properly; compared with embodiment 1, only one type of gear can be purchased and installed. Save time and effort.

[0036] For other structures, refer to Embodiment 1.

Embodiment 3

[0038] The rack and pinion elevator of this embodiment differs from Embodiment 1 in that:

[0039] Such as Figure 5 As shown, the driving part 3-1 uses two motors, each motor has a worm, and each worm is provided with a set of helical teeth to drive each gear set respectively. When installed, the helical teeth of the worm rotate in the opposite direction. Compared with Embodiment 1, when one of the motors fails, the other motor can continue to support the operation of the elevator for a short time.

[0040] For other structures, refer to Embodiment 1.

Abstract

The invention belongs to the technical field of elevators, and particularly relates to a gear and rack elevator. The gear and rack elevator comprises a transmission component and a carrier. The transmission component comprises a gear set and a driving component arranged in a hoistway, wherein the gear set comprises a plurality of transmission gears sequentially arranged in the hoistway direction;reversing members are arranged between the adjacent transmission gears to make the rotation directions of each transmission gear uniform; the carrier body is provided with a rack for meshing with thetransmission gear; and when the driving member drives the transmission gears to transmit, the plurality of transmission gears are sequentially engaged with the rack to drive the carrier to move in thedirection of the hoistway. According to the gear and rack elevator, the driving component is arranged in the hoistway and drives the transmission gears to drive the rack of the carrier body to move;the noise and vibration felt during the operation of the elevator are low; the maintenance and repair of the elevator are more convenient; and since the standardized production of the gear of the gearset can be achieved, the faster delivery and better economical efficiency are provided.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to a rack and pinion elevator. Background technique [0002] In the existing rack and pinion elevator, since the motor is installed on the car frame, when the elevator is working, the motor and the car frame move up and down at the same time. Related prior art such as: the patent document with application number CN201620244864.2 discloses a gear tooth The rack type safety elevator includes a rack, a moving part and a car; the moving part includes N gears and an elevator driving part, and N is a positive integer; the moving part is fixed in the car, and the rack is vertically fixed in the elevator shaft through the car In the track, multiple gears are meshed with the rack, and the elevator driving part is used to simultaneously drive multiple gears to rotate synchronously, so that when the multiple gears rotate, it can drive the car to move up and down along the rack; it also inclu...
