Abstract
The invention discloses an additional brake of an escalator. The additional brake of the escalator can guarantee the position precision of a main driving shaft of the escalator relatively to the step track when in braking and the generated impact force is little. The additional brake of the escalator comprises a linkage mechanism, a brake locking hook connected on the linkage mechanism, a plurality of brake blocks connected on the outer side surface of a main driving wheel and a brake electric magnet for controlling the action of the linkage mechanism; and each brake block is connected with a buffer block.
Description
Technical field
The additional brake that the present invention relates to use on the escalator.
Background technology
Existing additional brake of escalator comprises that brake electromagnet, interlinked mechanism, brake locking hook and several are connected the slipper on the main drive wheel lateral surface.At escalator in case of emergency, brake electromagnet makes the brake locking hook action through interlinked mechanism under the control of control system, and brake locking hook contacts with slipper, continues rotation to stop main drive wheel.The action of additional brake can produce huge impact power, influences the positional precision of escalator main drive shaft with respect to the step track, after action, need readjust the wasting manpower and material resources to the position of the relative step track of main drive shaft.In addition, excessive impulsive force also can make the passenger on the step produce violent rocking, and causes personal damage easily.
Summary of the invention
Technical matters to be solved by this invention provides a kind of additional brake of escalator, and this additional brake of escalator can guarantee the positional precision of escalator main drive shaft with respect to the step track at glancing impact, and the impulsive force of generation is little.
The present invention includes interlinked mechanism, be connected brake locking hook, several brake electromagnets that are connected the slipper on the main drive wheel lateral surface and are used to control the interlinked mechanism action on the interlinked mechanism, on each slipper, connect a bump rubber.
At escalator in case of emergency; Identical with existing additional brake; Brake electromagnet makes brake locking hook action through interlinked mechanism under the control of control system, and this moment and brake locking hook direct contact is bump rubber, and bump rubber is compressed the absorption impulsive force; Simultaneously power is passed to slipper and produce braking force, stop that main drive wheel continues rotation.When the additional brake of escalator among the present invention moves, can effectively alleviate impact, avoid destruction, save the work of artificial adjustment escalator main drive shaft positional precision; Produced simultaneously impulsive force is little, the injury that the passenger on the step who avoids step acutely to rock being brought causes.
As improvement of the present invention, said bump rubber is the elastic body of being processed by polyurethane material.
The bump rubber of being processed by polyurethane material has good buffering and wear resisting property.
As improvement of the present invention, slipper is four, ownership motion block with the center of circle of main drive wheel be the center, along on the lateral surface that circumferentially is evenly distributed in main drive wheel of main drive wheel.
Figure of description
Fig. 1 is the structural representation of additional brake of escalator;
Fig. 2 is the structural representation that connects the main drive wheel card of bump rubber.
The specific embodiment
As shown in Figure 1, the additional brake of escalator in this embodiment comprises interlinked mechanism 1, is connected brake locking hook 2, several slipper 3 on the interlinked mechanism 1 and is used to control the brake electromagnet 4 that interlinked mechanism 1 moves; Above-mentioned several slipper 3 are connected on the outside card of main drive wheel 5.On each slipper 3, connect a bump rubber 6.Preferably 1 said bump rubber 6 is elastic bodys of being processed by polyurethane material.
As shown in Figure 2, preferably adopt four slipper 3, ownership motion block 3 is that the center is along on the lateral surface that circumferentially is evenly distributed in main drive wheel 5 of main drive wheel 5 with the center of circle of main drive wheel 5.
Claims (3)
1. additional brake of escalator; Comprise interlinked mechanism, be connected brake locking hook, several brake electromagnets that are connected the slipper on the main drive wheel lateral surface and are used to control the interlinked mechanism action on the interlinked mechanism, it is characterized in that: on each slipper, connect a bump rubber.
2. additional brake of escalator according to claim 1 is characterized in that: said bump rubber is the elastic body of being processed by polyurethane material.
3. additional brake of escalator according to claim 1 is characterized in that: slipper is four, and ownership motion block is center, circumferentially being arranged in equably on the lateral surface of main drive wheel along main drive wheel with the center of circle of main drive wheel.
