Rail 8 and the servo-actuated guide rail 10 of lower level and lower bending section outlet, complete a circulation.If descending, otherwise.
In truss 17, as shown in figure 3, during boxing component 172 is welded under boxing component 171 and middle part on middle part
On the perpendicular component 173 in portion, and guide rail template 18 is then arranged on middle part boxing component 172 under boxing component 171 and middle part
On.Middle part outlet drives guide rail 6, loop to drive the servo-actuated guide rail 12 of guide rail 11, loop to install fixed against guide rail template 18
Position.
The both sides of step 5 of the escalator are each formed with the middle part of the anti-jump hook of step, the anti-jump hook of step and place side
Outlet drives guide rail 6 to coordinate；As shown in Figure 3, Figure 4, middle part outlet drives to be formed with the inside of guide rail and extends to guide rail
Protuberance outside template 18；The anti-jump hook of step is prominent to the direction for being close to guide rail template 18 and is driven positioned at middle part outlet
The protuberance lower section of dynamic guide rail 6, top and the middle part outlet of the anti-jump hook of step drive guide rail 6 protuberance bottom it
Between minimum perpendicular distance be not more than 4mm, as shown in Figure 4.
The anti-jump hook of step is L-shaped, and it includes that hook portion 51 outwardly, connection hook portion 51 are vertical with step 5
Portion 55, the hook portion 51 is located at the protuberance lower section that middle part outlet drives guide rail 6, as shown in Figure 4.Drive in middle part outlet
Dynamic guide rail 6 is step-like in two-stage, and to drive main wheel spigot surface 65, second step face is step accessory whorl to wherein First terrace
Spigot surface 66, the step main wheel 151 of escalator is driving operation on main wheel spigot surface 65, and step accessory whorl 54 is in step
Run on accessory whorl spigot surface 66.It is anti-jump working face A63 that middle part outlet drives the bottom surface of the protuberance of guide rail 6, and step is prevented
The top surface of hook portion 51 for jumping hook is anti-jump working face B52, and two anti-jump working faces constitute anti-pumping device.Middle part outlet drives and leads
The top surface of the protuberance of rail 6 is same plane with step accessory whorl spigot surface 66.Middle part outlet drive guide rail lateral surface be
Locating surface A61, bottom surface is mounting surface A62, and wherein locating surface A61 is closely pasted with the locating surface B181 of guide rail template 18
Close, mounting surface A62 is close to and fixation is installed on the mounting surface B182 of guide rail template 18.
The section of hook portion 51 of the anti-jump hook of step is circular or square, as shown in figure 5, when section is square, hook portion 51
Top surface (i.e. anti-jump working face B52) and middle part outlet drive guide rail 6 protuberance bottom surface (i.e. anti-jump working face A63)
There is an angle α between parallel, or both>0.The minimum perpendicular distance of anti-jump working face A63 and anti-jump working face B52
Less than or equal to 4mm (theoretical value 3.5), when being lifted on step accessory whorl 54, the anti-jump hook of step is also lifted on, Zhi Daofang
Untill jump working face B52 meets anti-jump working face A63.
Step shaft assembly 15 is arranged on and drives on main wheel spigot surface 65, and lateral surface and the middle part outlet of step main wheel 151 are driven
The theoretical gap a of the second confined planes 67 of dynamic guide rail 6 is 1mm, effectively prevents the left and right play of step shaft assembly 15.
It is the first confined planes 64, the vertical portion of the hook portion 51 of the anti-jump hook of step that middle part outlet drives the protuberance medial surface of guide rail 6
55 lateral surface is confined planes 53, and theoretical gap b therebetween is 6mm.Step 5 is arranged on step shaft assembly 15
On be relatively-stationary, so when step shaft assembly 15 occurs the play of most 1mm in a lateral direction, middle part is gone
It is then 5mm with the actual minimum theoretical gap of the confined planes 53 of the anti-jump hook of step that road drives the first confined planes 64 of guide rail 6,
Can so prevent the phenomenon of left and right jam during lift on the anti-jump hook of step.The medial surface of hook portion 51 of the anti-jump hook of step with
It is 5mm that middle part outlet drives the theoretical gap c between the protuberance medial surface of guide rail 6, even if left and right play, can also be protected
Demonstrate,prove anti-jump working face B52 has 4mm with the face that overlaps of anti-jump working face A63, prevents from deviating from middle part during lift on the anti-jump hook of step
Outlet drives the protuberance of guide rail 6.
Step is anti-jump, and position is relatively low when being hooked in outlet, and position is higher during loop, therefore by the position of boxing component 171 on middle part
Put low, and boxing component 171 is provided with breach in the correspondence position of the anti-jump hook of loop step on middle part, as shown in Figure 3 with
Ensure to be allowed when loop is run the anti-jump hook of step can pass through.
Anti-jump working face A is integrated in middle part outlet and driven on guide rail by the present invention, and anti-jump work is ensure that by machining mode
Make the positional precision between face A and step accessory whorl spigot surface, so as to ensure that middle part outlet drives the anti-jump working face of guide rail
Positional precision between A and the anti-jump working face B of the anti-jump hook of step, realizes anti-bouncing function, while present invention eliminates
Anti-jump guide rail in existing Anti-tripping structure, had both reduced material cost and installation cost, and anti-jump effect is improve again.
The present invention is described in detail above by specific embodiment, the embodiment is only of the invention preferable
Embodiment, it not limits the invention.Without departing from the principles of the present invention, those skilled in the art
Equivalent replacement and improvement that the shape of guide rail or the shape of the anti-jump hook of step etc. are made are driven to middle part outlet, is regarded as
In the technology category that the present invention is protected.
