Embodiment Construction
[0025] Such as Figures 1 to 3 As shown, an escalator includes a guide rail height adjustment device 1, and the guide rail height adjustment device 1 includes a bracket 10 connected with the guide rail support plate 4, a screw rod 20 connected with the guide rail, and the bracket 10 and the screw rod 20 are oppositely provided with A through hole, the end of the screw 20 away from the guide rail passes through the through hole, the screw 20 is provided with a first nut 30 and a second nut 40, the first nut 30 is located on the upper side of the bracket 10, the The second nut 40 is located on the lower side of the bracket 10 . The guide rail described in this embodiment is the lower advancing side rail 2 , and the guide rail height adjusting device 1 adjusts the height difference between the lower advancing side rail 2 and the lower turning guide rail 3 .
[0026] When the height of the guide rail needs to be lowered, the first nut 30 should be screwed upwards, and then the se...

The invention relates to a guide rail height adjusting device and method as well as an escalator. The guide rail height adjusting device comprises a bracket connected with a guide rail support plate, a screw rod connected with a guide rail and a through hole formed in the position where the bracket and the screw rod are opposite, wherein one end, far away from the guide rail, of the screw rod penetrates through the through hole; a first nut and a second nut are arranged on the screw rod, the first nut is located on the upper side of the bracket, and the second nut is located on the lower side of the bracket. When the guide rail is adjusted downwards, the first nut is screwed upwards, then the second nut is screwed upwards, the screw rod bears the downward pull force, and the screw rod moves downwards under the action of the pull force and drives the guide rail connected with the screw rod to move downwards; when the guide rail is adjusted upwards, the second nut is screwed downwards, then the first nut is screwed downwards, the screw rod bears upward jacking force, and the screw rod moves upwards under the action of the jacking force and drives the guide rail connected with the screw rod to move upwards. Compared with a traditional mode, a gasket is not required to be increased or decreased, the operation is simpler and more convenient, besides, the height adjustment is more accurate, and stepless regulation can be realized.
Description
technical field [0001] The invention relates to elevator technology, in particular to a guide rail height adjusting device and method, and an escalator. Background technique [0002] Due to assembly errors and component manufacturing errors of escalators or sidewalks, height differences are likely to occur between adjacent rails, especially at the joint position of the lower forward side rail and the lower turning guide rail, which will affect the comfort of the step operation , and generate noise. The general height difference adjustment method mainly relies on adding and subtracting the gasket between the lower forward side rail and the guide rail support plate to adjust; when the lower forward side rail is higher than the flip guide rail, the adjustment process is: loosen the fixing bolts, take out the adjustment Spacers, and then tighten the fixing bolts; when the lower forward side rail is lower than the overturning guide rail, the adjustment process is: loosen the fix...
