Description
Technical field
The invention belongs in the safety component of escalator and moving sidewalk, be specifically related to a kind of driving chain tensioner chain rupture device, there is tensioner chain and detect 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 comparatively simple, and majority only can realize single tensioner or chain rupture function, as installed push rod on main machine base, by withstanding main frame backward, to reach the effect of tensioner driving chain, structure is simple, but cannot automatic tension when the later stage, chain was long, need artificial adjustment, make troubles and potential safety hazard to repair and maintenance work, and for example in certain position of driving chain, poke-rod type safety switch is installed, by after the action of chain self-weight press driving lever during chain rupture, safety return circuit main control system is out of service, structure is simple, but it is not high to detect stability, if may switch failure be caused after the change of installation site, cause potential safety hazard.
Through retrieval Chinese patent, about the invention of driving chain tensioner chain rupture device is few, the similar invention retrieved is all different from the technical scheme that the present invention relates to.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of driving chain tensioner chain rupture device.The real-time tensioner driving chain of this device, had both eliminated the work capacity of artificial adjustment tensioner degree, and had turn improved sensitivity and the precision of device, avoid safety misadventure to occur.
In order to solve the problems of the technologies described above, the present invention 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 least one spring is set between the two at fixed part and slipper and holds the groove of spring, directly compress and tensioner driving chain at the compact heap of the effect lower slider portion of elastic force, 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 chain rupture time, slipper entirety moves down with driving chain, make described switch head depart from described groove and backed down, force safety switch to external compression, triggering secure switch motion, thus make equipment out of service.
Described compact heap adopts nonmetallic wear-resistant material.
Described compact heap is set to bayonet socket suspension type and detachably changes structure,
The fixed part of described compacting part is fastened on truss by attaching parts, 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 respectively by fastener and slide rail, slide rail is C shaped piece, and C shaped piece 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 be separated with long bolt, in the groove of spring application in slipper.
Be provided with limited screw in described fixed part, limited screw is stuck in the vertical long groove that arranges in slipper, prevents slipper from departing from fixed part.
The present invention has following beneficial effect:
(1), the compact heap of compacting part is directly compressed driving chain under spring force, energy is tensioner driving chain in real time, decrease the work capacity of repair and maintenance personnel, improve repair and maintenance efficiency, avoid in use because people forgets the elasticity checking driving chain, and when causing driving chain long, the chain abnormal sound caused, serious wear, the hidden danger that driving efficiency is low, improves repair and maintenance efficiency.(2), compacting part side arranges safety switch and detects the location status of compact heap, when driving chain is long or chain rupture time, compact heap moves down along with driving chain; triggering secure switch motion; thus make equipment out of service, avoid safety misadventure to occur, the safety of protection passenger.The sensitivity and the precision comparison that detect the long or chain rupture of driving chain are high, and under spring force, device reaction is sensitiveer, and when detecting chain rupture, and any position chain rupture switch all can action 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 lower cliding friction of friction coefficient when compressing operating chain, not only serve tensioner effect, and can also the noise produced during work be dropped to minimum, and compact heap is convenient to change, not in maintain and replace.
