Problems solved by technology
The invention overcomes the disadvantages of the traditional chain-type escalator that the transmission parts are large in size, takes up a large space, and consumes high electric energy. The driving host of the traditional chain-type escalator needs to be installed in the upper machine room, resulting in a narrow maintenance space. Defects and the traditional chain escalator adopts worm gear reducer, the defect of low transmission efficiency

Embodiment Construction
[0016] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but not as a basis for limiting the present invention.
[0017] Example. A rack type escalator, such as figure 1 and figure 2 As shown, the structure of the escalator including the escalator truss 1, the driving host 2, the handrail system 3 and the ladder system 4 is characterized in that: the driving host 2 is installed in the middle of the escalator truss 1, and the output shaft is provided with There is a gear 5, and a rack 6 is correspondingly arranged above the gear 5, and the rack 6 is statically connected with the step shaft 7, and a handrail driving mechanism 8 is arranged above the rack 6.
[0018] Such as image 3 As shown, the drive host 2 includes a motor 9, the motor 9 is connected to the reducer 11 through a transmission belt 10, and the gear 5 is arranged on the output shaft of the reducer 11.
[0019] The reducer 11 is a two-stage he...

The invention discloses a rack type escalator. The rack type escalator disclosed by the invention comprises escalator structures such as an escalator truss, a driving host, a handrail strap system and an escalator way system, wherein the driving host is mounted at the middle part of the escalator truss; a gear is arranged on an output shaft; a rack is arranged above the gear and cascaded with an escalator level shaft; and a handrail strap driving mechanism is arranged above the rack. By adopting a novel escalator transmission way in the rack type escalator disclosed by the invention, the load born by a bending part of a transmission rack is less than the load born by a transmission chain of a chain type escalator, so that the rack type escalator disclosed by the invention has the advantages of being less in space occupation of the transmission part and low in power consumption. Tests show that compared with the chain type escalator, the power consumption of the rack type escalator is reduced by 20%; the driving host is mounted at the middle part of the escalator truss, so that the rack type escalator disclosed by the invention has the advantages of being large in maintaining space and convenient to maintain; and by adopting a two-level bevel wheel speed reducer, the transmission efficiency is high and reaches more than 95%.
Description
technical field [0001] The invention relates to a rack type escalator, which belongs to the technical field of elevators. Background technique [0002] With the development of the national economy, escalators have been widely used in places with a large flow of people (such as shopping malls, stations, etc.). The traditional chain escalator has the following defects: (1) The transmission chain is subjected to a huge load on the upper bending part, and in order to ensure the normal operation of the escalator, the size of the transmission part is designed to be large, resulting in a large space occupied and power consumption Higher; (2) The drive host of the traditional chain escalator needs to be installed in the upper machine room, resulting in narrow maintenance space; (3) The traditional chain escalator mainly uses worm gear reducer due to the structural characteristics of the limited transmission components , low transmission efficiency.
