Abstract
The armrest belt break protector includes level and rack. The level set below the armrest belt is provided with rolls and switch, and is mounted on the rack and connected to the rack through a rotation shaft. The rack fixed on the guide rail bracing plate is provided with offset preventing roll. The present invention is operated on lever principle, and in case of armrest belt break, the level is turned gravitationally to trigger the switch and stop the staircase. The present invention has unique design, novel structure, easy installation and regulation and high safety and reliability, and may be used widely for escalator or moving sidewalk.
Description
Technical field
The present invention relates to a kind of fender guard, relate in particular to the armrest belt break protector of escalator or moving sidewalk.
Background technology
The handrail of escalator or moving sidewalk is a kind of movable parts for passenger's use, and the passenger that normally operates to of handrail provides safety control, and its operational effect also directly affects passenger's comfort.At present, most of armrest belt break protectors adopt the spring structure design, and the spring that often is under the compressive state is easy to lose efficacy, and is difficult for regulating, and cost is high again, installation and maintenance inconvenience.Because due to the long-term use and himself process characteristic of handrail, the situation that fracture takes place handrail happens occasionally, therefore, it is necessary to design and develop armrest belt break protector.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of novel structure, easy for installation, armrest belt break protector that use cost is lower are provided, monitor so that whether the handrail of escalator or moving sidewalk fracture is taken place.
Purpose of the present invention is achieved through the following technical solutions:
Armrest belt break protector; it is characterized in that: comprise lever and support; lever is arranged on the below of handrail, and roller is housed on the lever, and described lever below is provided with switch; switch and lever are rack-mount; lever links to each other by S. A. with support, lever with respect to rotating shaft center about two arm of forces unequal, and described switch is positioned at the below of the long arm of force one end of lever; described support is fixed on the guide rail fagging, and anti-inclined to one side roller also is installed on support.
Further, above-mentioned armrest belt break protector, roller are installed in the both ends of lever.
Further, above-mentioned armrest belt break protector, zone relative with switch on lever is provided with block.
The outstanding substantive distinguishing features and the obvious improvement of technical solution of the present invention is mainly reflected in: its ingenious lever principle of having used, if the handrail phenomenon of rupture takes place, lever will overturn under the effect of gravity, thereby trigger switch action, stop staircase or moving sidewalk, thus avoid taking place safety misadventure.The design of this device uniqueness, novel structure, be easy to install regulate, safe and reliable to operation, be widely used in handrail to escalator or moving sidewalk and whether fracture takes place monitor, application prospect is had an optimistic view of.

The specific embodiment
Shown in Fig. 1～2; a kind of armrest belt break protector; be arranged at the lever that has roller 52 of handrail 1 below, the both ends that roller 5 is installed in lever 2; lever 2 belows are provided with switch 7, are used for fixing the support 8 of switch 7 and lever 2, and support 8 is provided with the anti-inclined to one side roller 3 of handrail; support 8 is fixed on the guide rail fagging 9; support 8 links to each other by S. A. 4 with lever 2, lever 2 with respect to S. A. 4 centers about two arm of forces unequal, switch 7 is positioned at the below of the lever 2 long arm of force one ends.
It should be noted that support 8 is fixed on the guide rail fagging 9, simultaneously again can floatless switch 7 on the support 8, anti-inclined to one side roller 3 can be installed.Support 8 is by S. A. 4 truck dead levers 2, and the center of gravity of lever 2 and its centre of gration are not overlapping.When equipment normally moved, roller 5 and anti-inclined to one side roller 3 guaranteed handrail 1 along correct track operation, after handrail 1 ruptures, and by gravity, lever 2 overturns, trigger switch 7, thus make equipment out of service.
During concrete the application, handrail 1 is in the direction operation of the support lower edge regulation of the guiding of anti-inclined to one side roller 3 and roller 5, and switch 7 has certain clearance with block 6 on the lever 2, and roller 5 rotates under the pressure effect of handrail 1 and keeping balance simultaneously.In case the armrest belt break phenomenon takes place; handrail 1 will lose for the pressure of two rollers 5; because action of gravity; lever 2 will overturn around S. A. 4; the block 6 of lever 2 belows will touch switch 7 this moment; thereby cut off the electricity supply, make that escalator or moving sidewalk are out of service, thereby play the safety guard-safeguard effect.
In sum, the present invention has utilized lever principle, if the handrail phenomenon of rupture takes place, lever overturns by gravity, thus the trigger switch action, stop staircase or moving sidewalk.The design of this device uniqueness, novel structure, be easy to adjusting, safe and reliable to operation is installed, whether the handrail that is widely used in monitoring escalator or moving sidewalk ruptures.
Below only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the rights protection scope of the present invention.
