Description

The disjunctor bidirectional escalator

The utility model relates to a kind of escalator, particularly about a kind of disjunctor bidirectional escalator that can carry out the uplink and downlink operation simultaneously.

As everyone knows, since escalator comes out, bring great convenience for our life, it has become indispensable significant transportation instrument in the modern life, and still, the high cost of escalator has also greatly limited popularizing and using of it.Existing as shown in Figure 2 escalator, every escalator all is the delivery system of a cover independent operating, can only finish a transportation work on the direction simultaneously.Operating step is only being born the work of transporting the passenger at the step of surface operation, and remaining surpass step more than half all the vertical duction wall 47 by the escalator two ends change escalator inside over to and do circular flow.We know that step is the maximum parts of quantity in the escalator, the escalator step number of a little hoisting depth is about 50～100, the escalator step number of a big hoisting depth is about 600～700, so the quantity of step is the greatest factor that determines an escalator cost and weight.And because the step of existing escalator is to move in the staircase inner loop, so must strengthen the structure of steelframe, the weight that this has not only increased staircase has again increased the escalator occupation space, and thick and heavy framework more influences the difficulty of the attractive in appearance and construction and installation of environment.Also have a bit, because the existing every portion of escalator unidirectional operation simultaneously, thus to solve the simultaneously upper and lower problem of passenger, just must two escalators of design and installation, must increase like this and invest and over-the-road expense.

The purpose of this utility model provides a kind of disjunctor bidirectional escalator, it can finish the work of conveying people up and down simultaneously, just its work efficiency is equivalent to the usefulness of two existing escalators, and its step quantity, actuating unit, steel framed structure and overall weight have only two existing escalators half, so just can greatly reduce escalator cost, save material, alleviate escalator weight, save the space, reduce erected cost, lower operating cost.

To achieve these goals, technical solution of the present utility model is: a kind of disjunctor bidirectional escalator is by up staircase, down escalator, step, handrail substantially, turns to sprocket wheel, actuating unit, driving chain sprocket, conduction chain, backplate, cover plate and steelframe to be constituted; Described actuating unit is installed in the steelframe of staircase upper end, and the driving chain wheel that is installed on the drive shaft by the driving chain drive rotates together with driving chain sprocket, driving chain sprocket drives conduction chain, and the main axle that the drive web on the conduction chain promotes to be installed on the step bracket drives the step operation.Described step is made of pedal, preceding kickplate, back kickplate, support and jockey pulley support, an end that is contained in the main axle on the support is equipped with main wheel and outer traction hook, on the outer traction hook hook wheel is housed, the other end of main axle is equipped with main wheel and interior conduction chain, and jockey pulley is installed on the jockey pulley support by turning cylinder; Interconnect common operation by interior conduction chain and outer traction hook between step and the step, the operation attitude of the level of step, lifting or decline is controlled by the terraced guide rail system that is installed in that main wheel guide rail, jockey pulley guide rail and the anti-rail of main wheel on the steelframe formed, and terraced guide rail system makes the pedal maintenance level of the step that runs to any position all the time; In the middle of up staircase and down escalator two ends, be equipped with and turn to sprocket wheel, described turn to sprocket wheel to be installed on the steering shaft and promote by the gear teeth that turn to sprocket wheel in bearing pin on the conduction chain make step finish 180 ° of horizontal turning operations; Step run to the staircase two ends ready about before, the hook wheel of the outer traction hook on the main axle under the guiding of the oblique rail of opening of lifting oblique rail of hook and the anti-rail of lock hook will outside draw hook and remove from main axle, and rely on and lift the hook wheel that moves on the hook guide rail and outer traction hook is lifted all the time move to step and turn to end, step finish turn to reenter lifting operation before, the hook wheel of outer traction hook under the guiding of the oblique rail of inlet of oblique rail of hook and the anti-rail of lock hook will outside draw hook and hang on the main axle again; Be installed in that identical two gears on drive shaft and the reverse drive main shaft make driving chain sprocket and oppositely the rotating speed equidirectional of driving chain sprocket is opposite, thereby make up staircase and the down escalator can be with identical speed and opposite direction operation.

In one embodiment, the actuating device of staircase can also be designed to cancel the driving system that driving chain sprocket, auxiliary sprocket wheel and conduction chain are constituted, the drive sprocket and the drive that are installed on the steering shaft by the driving chain direct drive on the actuating unit turn to sprocket rotation, and make step circular flow by turning to sprocket wheel to drive interior conduction chain.

In another embodiment, as long as steelframe, terraced guide rail system and step appropriate change just can be designed level or the two-way moving sidewalk of light grade disjunctor.

The utility model is compared with prior art and can be made step quantity, actuating unit, steel framed structure reduce half under the situation of finishing identical work capacity, thereby reduced productive costs, save material, alleviate staircase weight, save the space, reduce erected cost and operating cost, and because the circulation draw of up staircase and down escalator, the gravity of passenger on the down escalator is understood the gravity of the passenger on the up staircase of counteracting partly, thereby has reduced the load of actuating unit.
