Abstract
The utility model discloses a kind of handrail belt pressing device, comprise handrail, truss, friction wheel, pressure zone roller set, described handrail is located between described friction wheel and described pressure zone roller set, also comprises arc pressuring plate, electromagnet and the second permanent seat; Described arc pressuring plate is located at the outside of described pressure zone roller set, contacts with described pressure zone roller set, and described electromagnet is fixed on described truss by described second permanent seat, and described electromagnet contacts with described arc pressuring plate.The utility model is by increasing the electromagnet controlled by control housing; when staircase runs; electromagnet obtains electric promotion arc pressuring plate extruding pressure zone roller set, and then increases the driving friction force of handrail, avoids handrail skidding; when staircase is out of service; electromagnet is failure to actuate, and reduce handrail pressure, arc pressuring plate can unclamp; decrease the pressure of pressure zone roller set to handrail, actv. protects handrail.
Description
Technical field
The utility model relates to a kind of handrail device, is specifically related to a kind of handrail belt pressing device.
Background technology
The handrail belt pressing device of a lot of escalator is all use roller set to compress handrail under spring tension at present, handrail is allowed to rotate with friction wheel and to realize the motion of handrail, but because the contact surface of idler wheel surface and handrail is linear contact lay, easily occur that friction force occurs handrail skidding not, affect the boarding safety of passenger, although increase spring force can improve skidding, but in the excessive situation of pressure, especially when staircase is out of service, handrail is subject to the pressure continued of roller, handrial belt there will be obvious impression, affect the attractive in appearance of handrail and intensity.
Summary of the invention
For solving the problem, the purpose of this utility model is to provide a kind of handrail belt pressing device, by increasing the electromagnet controlled by control housing, when staircase runs, electromagnet obtains electric promotion arc pressuring plate extruding pressure zone roller set, and then increase the driving friction force of handrail, avoid handrail skidding, extend the service life of handrail.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of handrail belt pressing device, comprise handrail, truss, friction wheel, pressure zone roller set, described handrail is located between described friction wheel and described pressure zone roller set, also comprises arc pressuring plate, electromagnet and the second permanent seat; Described arc pressuring plate is located at the outside of described pressure zone roller set, contacts with described pressure zone roller set, and described electromagnet is fixed on described truss by described second permanent seat, and described electromagnet contacts with described arc pressuring plate.
Further, described pressure zone roller set two ends are fixed on described truss respectively by the first permanent seat and the 3rd permanent seat.
Further, described electromagnet connection control cabinet.
The beneficial effects of the utility model are:
The utility model is by increasing the electromagnet controlled by control housing; when staircase runs; electromagnet obtains electric promotion arc pressuring plate extruding pressure zone roller set, and then increases the driving friction force of handrail, avoids handrail skidding; when staircase is out of service; electromagnet is failure to actuate, and reduce handrail pressure, arc pressuring plate can unclamp; decrease the pressure of pressure zone roller set to handrail, actv. protects handrail.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification sheets, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.Detailed description of the invention of the present utility model is provided in detail by following examples and accompanying drawing thereof.
