Embodiment
Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model is clearly and completely described.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained without creative efforts
Every other embodiment, shall fall within the protection scope of the present invention.
In the prior art, subway shield door support device generally carries out load-bearing and slip using line slideway.Its structure
As shown in Figure 1, sliding door door body 1 is connected with shield door supporting rack 2, shield door supporting rack 2 can be by line slideway 5 in sliding block
Slided on 4.Motor 7 is installed in support base 6, drives shield door supporting rack 2 to slide by synchronous belt 3.Use line slideway
Shield door is more time-consuming, it is necessary to periodically fill lubricant grease.Simultaneously as line slideway is a precision component, its maintenance
It is also not convenient enough with dismounting.
The subway shield door support device of the utility model, as shown in Figs. 1-5, including shield door supporting rack 2 and support base
6；2 frame body side of shield door supporting rack opens up support slot 2-1, installs back-up roller wheel 8 on support base 6, back-up roller wheel 8 is assemblied in branch
Support in groove 2-1, when making the movement of shield door supporting rack 2, shield door supporting rack 2 is rolled with support base 6 and connected.Shield door supporting rack 2
Supporting surface 10 be connected with shield door door body 1 using screw.The inside of support base 6 installation motor 7, output terminal and the active of motor 7
Belt wheel 11 connects, and driving pulley 11 is connected with driven pulley 12 by synchronous belt 3, and synchronous belt 3 is connected with shield door supporting rack 2,
Drive shield door supporting rack 2 to move, be further driven to 1 folding of shield door door body.Subway shield door support in the utility model
Device, compared to using line slideway load-bearing and the structure slided, under square one, frictional force reduces, and reduces shield door branch
The wear rate of support 2 and support base 6.
There are the gravity of vertical direction and the thrust of horizontal direction to support base 6 because of shield door door body 1, therefore need setting can be with
Bear the structure of vertical forces and horizontal direction power.Foregoing back-up roller wheel 8 be primarily subjected to for vertical forces.To bear water
Flat direction force is provided with guide groove 2-2 and guide roller 9；As shown in Fig. 2, guide groove 2-2 is opened in 2 frame body of shield door supporting rack
Bottom side, guide roller 9 are installed on support base 6, and guide roller 9 is located at the lower section of back-up roller wheel 8, is assemblied in guide groove 2-2, makes
When shield door supporting rack 2 moves, shield door supporting rack 2 is moved along guide groove 2-2, ensures the direction of motion.The diameter of back-up roller wheel 8
