Description
Technical field
The utility model belongs in the safety component of escalator and moving sidewalk, is specifically related to a kind of driving chain tensioner chain rupture device, has tensioner chain and detects driving chain chain rupture function.
Background technology
Chain tensioner chain rupture device is a part for escalator and footway safety device system, existing driving chain tensioner or chain rupture device are comparatively simple, and most single tensioner or chain rupture functions of only realizing, as push rod is installed on main machine base, by withstanding backward main frame, to reach the effect of tensioner driving chain, simple in structure, but cannot automatic tension when the later stage, chain was long, need artificial adjustment, to repair and maintenance, work is made troubles and potential safety hazard, and for example in certain position of driving chain, poke-rod type safety switch is installed, after moving by chain self-weight press driving lever during chain rupture, safety return circuit main control system is out of service, simple in structure, but it is not high to detect stability, if installation site may cause switch failure after changing, cause potential safety hazard.
Through retrieval Chinese patent, the utility model of relevant driving chain tensioner chain rupture device is few, and the technical scheme that the similar utility model retrieving all relates to from the utility model is different.
Utility model content
Technical problem to be solved in the utility model is: a kind of driving chain tensioner chain rupture device is provided.This installs real-time tensioner driving chain, has both saved the work capacity of artificial adjustment tensioner degree, has improved again sensitivity and the precision of device, avoids safety misadventure to occur.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A kind of driving chain tensioner chain rupture device, comprise compacting part, it is characterized in that: described compacting part comprises fixed part and slipper, bearing fit between fixed part and slipper, and at fixed part and slipper, at least one spring and the groove that holds spring are set between the two, compact heap in the effect lower slider part of elastic force directly compresses also tensioner driving chain, safety switch is arranged on described fixed part, the switch head of safety switch is pressed on the groove of slipper, when driving chain is long or during chain rupture, slipper integral body moves down with driving chain, make described switch head depart from described groove and be backed down, force safety switch to external compression, touch safety switch action, thereby make equipment out of service.
Described compact heap adopts nonmetallic wear-resistant material.
Described compact heap is made as bayonet socket suspension type and detachably changes structure,
The fixed part of described compacting part is fastened on truss by link, described attaching parts is fixed by slide rail and truss, and attaching parts is provided with slotted hole, and slotted hole is connected and fixed by fastener and slide rail respectively, slide rail is C type part, and C type part can hold the head of described fastener.
Described spring is arranged between upper spring seat and lower spring cup, is provided with screw thread in lower spring cup, and upper lower spring cup is pinned by screw thread by long bolt, during mode of operation, turn long bolt, makes lower spring cup separated with long bolt, in the groove of spring application in slipper.
In described fixed part, be provided with limited screw, limited screw is stuck in the vertical long groove arranging in slipper, and anti-skidding partly departs from fixed part.
The utlity model has following beneficial effect:
(1), the compact heap of compacting part is directly compressed under the effect of spring force to driving chain, energy is tensioner driving chain in real time, reduced repair and maintenance personnel's work capacity, improved repair and maintenance efficiency, avoided in use because people forgets the elasticity that checks driving chain, and while causing driving chain long, the chain abnormal sound causing, serious wear, the hidden danger that driving efficiency is low, improves repair and maintenance efficiency.(2), compacting part one side arranges the location status that safety switch detects compact heap, when driving chain is long or during chain rupture, compact heap is along with driving chain moves down; the action of triggering safety switch; thereby make equipment out of service, avoid safety misadventure to occur, protection passenger's safety.Detect driving chain sensitivity and ratio of precision long or chain rupture higher, under the effect of spring force, device reaction is sensitiveer, and while detecting chain rupture, arbitrary position chain rupture switch all can move under elastic force effect, without blind area, dead angle, and raising safety performance.(3), because compact heap adopts nonmetallic wear-resistant material, so compact heap only produces the cliding friction that friction coefficient is lower when compressing operating chain, not only played tensioner effect, and can also the noise that when work produces be dropped to minimum, and compact heap is convenient to change, not in maintain and replace.
