Abstract
The utility model relates to a threshold of subway shield door, include preceding threshold and back threshold, preceding threshold and back threshold pass through the grafting structure grafting amalgamation of tip each other, and preceding threshold passes through support element with the back threshold and installs subaerial. Support element includes lower margin, concrete bolt and backup pad, has the mounting groove in the front on threshold and the back threshold, and the backup pad cartridge is in the mounting groove, and lower margin and backup pad threaded connection support the threshold, and the concrete bolt passes the backup pad and twists ground, produces decurrent pulling force to the threshold. The amalgamation of pegging graft of mode that slot on the interior tip of preceding threshold and the grafting structure branch of the tip of back threshold plug and the back threshold on maybe the interior tip of qianmen threshold, preceding threshold and back threshold inserted the slot through the plug. The beneficial effects of the utility model are that: simple structure, manufacturing is convenient, and the stable performance is reliable, and is non -maintaining.
Description
Technical field
The utility model relates to a kind of threshold of subway shield door.
Background technology
The doorsill structure of domestic conventional subway shield door uses the carbon steel structure of outer cover corrosion resistant plate to support, and because material is different, easily has electrochemical corrosion.Because of restrictions such as sheet metal processes, threshold straightness accuracy and outward appearance have problems.Threshold bottom also needs to join complicated T-shaped adjustment seat, in order to support this threshold.Complex structure, regulated quantity is little.
Utility model content
The technical problems to be solved in the utility model is: existing shield door doorsill structure is more miscellaneous, and installation and maintenance difficulty is large.
The utility model solves the technical scheme that its technical problem adopts: a kind of threshold of subway shield door, comprise front door sill and back door threshold, front door sill and back door threshold are each other by the connected structure grafting split of end, and front door sill and back door threshold are installed on the ground by support unit.
Further restriction, support unit comprises lower margin, concrete screw-bolt and gripper shoe, front door sill and back door threshold has mounting groove, gripper shoe is inserted in mounting groove, lower margin is threaded with gripper shoe, lower margin is supported threshold by gripper shoe, and concrete screw-bolt is screwed into ground through gripper shoe, and concrete screw-bolt produces downward pulling force by gripper shoe to threshold.This support unit makes door sill height adjusting range greatly strengthen.
Further restriction, mounting groove is stamped cover plate.
Further restriction, back door threshold surface has the groove installing phosphor strip.Phosphor strip is used for reminding passengers and gets on or off the bus attention.
Further restriction, the outer end of back door threshold is provided with rubber strip.Rubber strip carries out security protection, to ensure that rubber strip outer distance floor compartment width is in gauge claimed range.
Further restriction, the outer end of back door threshold has T-slot, and rubber strip is arranged on the outer end of back door threshold by bolt, embeds T-slot for the head end installing the bolt of rubber strip.
Further restriction, the connected structure of the end of front door sill and back door threshold is the slot on the inner end of plug on the inner end of front door sill and back door threshold respectively, and the mode that front door sill and back door threshold insert slot by plug carries out grafting split.
Further restriction, back door threshold has the guide groove coordinated with slip gate guide shoe.
Further restriction, front door sill and back door threshold are aluminium extruded sections.
Further restriction, the bottom of lower margin has felt pad, has insulation sleeve between concrete screw-bolt and gripper shoe.Felt pad and insulation sleeve make threshold keep insulating with the earth.
The beneficial effects of the utility model are: structure is simple, and convenient processing and manufacture is stable and reliable for performance, non-maintaining.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated;
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of support unit of the present utility model;
Wherein, 1. front door sill, 2. back door threshold, 3. lower margin, 4. concrete screw-bolt, 5. gripper shoe, 6. cover plate, 7. phosphor strip, 8. rubber strip, 9. slip gate guide shoe, 10. felt pad, 11. insulation sleeves.
Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of threshold of subway shield door, comprises front door sill 1 and back door threshold 2, and front door sill 1 and back door threshold 2 are each other by the connected structure grafting split of end, and front door sill 1 and back door threshold 2 are installed on the ground by support unit.Front door sill 1 and back door threshold 2 are aluminium extruded sections.The connected structure of the end of front door sill 1 and back door threshold 2 is the slot on the inner end of plug on the inner end of front door sill 1 and back door threshold 2 respectively, and the mode that front door sill 1 and back door threshold 2 insert slot by plug carries out grafting split.
Support unit comprises lower margin 3, concrete screw-bolt 4, gripper shoe 5, front door sill 1 and back door threshold 2 has mounting groove, gripper shoe 5 is inserted in mounting groove, lower margin 3 is threaded with gripper shoe 5, lower margin 3 is supported by gripper shoe 5 pairs of thresholds, concrete screw-bolt 4 is screwed into ground through gripper shoe 5, and concrete screw-bolt 4 produces downward pulling force by gripper shoe 5 pairs of thresholds, makes threshold firmly stable.After treating that front door sill 1 and back door threshold 2 are assembled by support unit, at mounting groove upper cover upper cover plate 6, appearance looks elegant, easy for installation.The bottom of lower margin 3 has felt pad 10, has insulation sleeve 11 between concrete screw-bolt 4 and gripper shoe 5.
Back door threshold 2 surface has the groove installing phosphor strip 7.
The outer end of back door threshold 2 is provided with rubber strip 8.The outer end of back door threshold 2 has T-slot, and rubber strip 8 is arranged on the outer end of back door threshold 2 by bolt, embeds T-slot for the head end installing the bolt of rubber strip 8.
Back door threshold 2 has the guide groove coordinated with slip gate guide shoe 9.
When mounted, first fix front door sill 1, after slip gate guide shoe 9 coordinates with back door threshold 2 and installs, fixing back door threshold 2.
