Abstract

The present invention discloses escalator, and is especially single driving bidirectional coupled escalator driven with one main driving mechanism. The single driving bidirectional coupled escalator includes one kind one main driving mechanism and two bidirectional escalators, and features the two-stage bevel gear reversing mechanism, through which the main driving mechanism drives two bidirectional escalators simultaneously. The two-stage bevel gear reversing mechanism includes three bevel gears, including the left one meshed to the main driving shaft in the left escalator, the right one meshed to the main driving shaft in the right escalator, and the middle one meshed to the right one and the left one for two-stage reversing transmission. The present invention has the advantages one reasonable structure, low cost and low power consumption.

Example Embodiment

[0011] The content and embodiments of the present invention are further described below in conjunction with the accompanying drawings.
[0012] See figure 1 This embodiment is composed of two sets of left and right two-way escalators, a main drive device III and a two-stage bevel gear reversing device IV. The two sets of left and right two-way escalators include a right escalator drive device I and a left escalator drive device placed side by side II. The left escalator driving device II is composed of the left driving main shaft 12, the left first step transmission sprocket 13, the left second step transmission sprocket 11 and the left brake disc 14. The left first step transmission sprocket 13 and the left second The step transmission sprocket 11 is fixedly connected to the two ends of the left driving main shaft 12, and the left brake disc 14 is fixedly connected to the left first step transmission sprocket 13. The right escalator drive device I consists of the right drive spindle 3, the right first step transmission sprocket 6, the right second step transmission sprocket 4 and the right brake disc 5. The right first step transmission sprocket 6 and the right second step transmission The sprocket 4 is fixedly connected to both ends of the right drive main shaft 3, and the right brake disc 5 is fixedly connected to the right second step transmission sprocket 4.
[0013] The main driving device III includes a host 1, a drive chain 2 and a drive sprocket 7. The drive sprocket 7 is fixedly connected to the right first step transmission sprocket 6, and the host 1 is connected to the drive sprocket 7 through the drive chain 2.
[0014] The two-stage bevel gear reversing device IV includes a left bevel gear 10, a right bevel gear 8 and a middle bevel gear 9. The left bevel gear 10 and the left drive main shaft 12 of the left escalator drive device II are connected to each other by keys, and the right bevel gear 8 is The right drive main shaft 3 in the right escalator drive device I is connected to each other by a key, and the left and right bevel gears 10 and 8 mesh with each other through the middle bevel gear 9 to achieve two-stage reversing transmission, in which the bevel gear 9 and the right bevel gear 8 realizes one-stage reversing transmission, and left bevel gear 10 and middle bevel gear 9 realize two-stage reversing transmission. In addition, the left and right bevel gears 10, 3 can also be connected to the left and right drive spindles 12, 3 through splines or couplings.
[0015] In this embodiment, a set of main drive device III is used to simultaneously drive two parallel right escalator drive devices I and left escalator drive device II, between the two parallel escalators originally independent right escalator drive device I and left escalator drive device II. A set of two-stage bevel gear reversing device IV is added to make it a set of linkage drive mechanism. The steps and step chains running in two directions in the single-drive two-way escalator are independent of each other, and are respectively driven by the right first step transmission sprocket 6 and the right second step transmission sprocket 4 in the right escalator drive device 1, and the left The left first step transmission sprocket 13 and the left second step transmission sprocket 11 in the escalator driving device II are driven.
[0016] When working, the host 1 drives the right escalator drive device I to rotate in one direction through the drive chain 2, and the right escalator drive device I completes the two-stage reversal through the two-stage bevel gear reversing device IV and then drives the left escalator drive device II to rotate in the opposite direction. , So as to achieve the purpose of a group of main driving device III simultaneously driving two two-way parallel escalators.
