Description
Technical field
Headstock gear technical field is the utility model is related to, especially a kind of anti-top lock screw open-close machine gate.
Background technology
Worm-type open-close machine structure is very simple, and the simplicity that also compares of installation, be widely used in the culverts and water gates of channel with
And the gate opening/closing on water diversion project, still, in use, top lock accident often occurs.
Top lock accident be gate in the process of running, the barrier such as the floating object such as trees or stone takes lock to by high-velocity flow
Bottom or be flushed in lock groove is blocked, if now closed shutter, when gate lips are not in contact with to being obscured by an obstacle before pocket floor
Counter-force is produced, but the spacing mark or limit switch on screw rod do not have also in place, not playing spacing shutdown or prompting operating personnel stop
The effect of machine, therefore operating personnel will not shut down, headstock gear will drive gate to continue to push, when counter-force exceedes headstock gear or opens and closes platform
When bearing endurance, will also occur push up lock accident.
Utility model content
In order to overcome the shortcomings of that existing screw open-close machine easily occurs to push up lock accident, the utility model provides a kind of anti-
Lock screw open-close machine gate is pushed up, when wanting closed shutter, gate declines, by gate to stopping the extruding of expansion plate and then drive
Compression spring, so as to which spring and stop expansion plate are squeezed into inside lock groove, gate falls realization and closes lock, its is closed whole lock
Groove, spring, which is in extended configuration, when gate is in open mode, in anti-top lock frame members will stop that expansion plate is placed in lock groove
At mouthful.
Technical scheme is used by the utility model solves its technical problem：A kind of anti-top lock screw open-close machine gate,
Including headstock gear body, screw rod and gate, gate two sides and lower section are provided with anti-top lock frame members, and top lock frame members include
Doorframe shell, doorframe enclosure are provided with spring and stop expansion plate.
Further, the lock groove for serving as gate operation including is provided with doorframe shell.
Further, including stop that expansion plate includes stopping expansion plate bottom plate, stops expansion plate side plate and stop flexible draw
Guide plate.
Further, including stop expansion plate side plate and stop that flexible directing plate is connected through the hinge, stop flexible guiding
Plate is connected through the hinge on the inside of lock groove on cell wall.
Further, including spring one end is fixed on and stopped on expansion plate, and the other end is fixed on lock groove inwall.
The beneficial effects of the utility model are the anti-top lock screw open-close machine gate of one kind of the present utility model, to avoid tree
The barrier such as the floating objects such as wood or stone is taken to pocket floor or is flushed in lock groove and blocks by high-velocity flow, and then avoids barrier card
In lock groove headstock gear continue to drive gate when pushing caused counter-force exceed headstock gear or open and close the bearing endurance of platform and send out
The problem of raw top lock accident.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the partial enlarged drawing at A in Fig. 1.
1. headstock gear body in figure, 2. screw rods, 3. gates, 4. anti-top lock frame members, 5. doorframe shells, 6. springs, 7.
Stop expansion plate, 8. lock grooves, 9. stop expansion plate bottom plate, and 10. stop expansion plate side plate, and 11. stop expansion plate, 12 hinges.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of anti-top lock screw open-close machine gate, including headstock gear body
1st, screw rod 2 and gate 3, the two sides of gate 3 and lower section are provided with anti-top lock frame members 4, and anti-top lock frame members 4 are included outside doorframe
Shell 5, the inside of doorframe shell 5 are provided with spring 6 and stop expansion plate 7.
When wanting closed shutter 3, gate 3 declines, and compression bullet is driven to stopping the extruding of expansion plate 7 by gate 3
Spring 6, so as to which spring 6 and stop expansion plate 7 are squeezed into inside lock groove 8, gate 3 falls realization and closes lock, its is closed whole lock
Groove, spring 6, which is in extended configuration, when gate 3 is in open mode, in anti-top lock frame members 4 will stop that expansion plate 7 is placed in
At 8 mouthfuls of lock groove, avoid the barriers such as the floating objects such as trees or stone and taken to pocket floor by high-velocity flow or be flushed in lock groove 8 and block
Firmly.
The lock groove 8 for serving as the operation of gate 3 is provided with doorframe shell 5, stop expansion plate 7 include stopping expansion plate bottom plate 9,
Stop expansion plate side plate 10 and stop flexible directing plate 11, stop expansion plate side plate 10 and stop that flexible directing plate 11 passes through hinge
12 connections, stop that flexible directing plate 11 is connected on the inner side cell wall of lock groove 8 by hinge 12.Gate 3 is located in doorframe shell 5
In the lock groove 8 in portion, when down declining, the bottom side angle of gate 3 first acts on the flexible directing plate 11 of stop, stops flexible directing plate 11
Driven by hinge 12 and spring 6 and stop that flexible side plate 10 slowly moves to the inwall of lock groove 8, and then realized and pack up, gate 3 is without hindrance
Hinder and move down, until contact stops expandable bottom plate 9, by the deadweight of gate 3 and the downward active force of screw rod 2 to stopping flexible bottom
Plate 9 carries out extruding and packed up, and realizes the closure of gate 3.
The one end of spring 6, which is fixed on, to stop on expansion plate 7, and the other end is fixed on the inwall of lock groove 8.Spring 6 plays extruding and received
While tight stop expansion plate 7, spring 6 also functions to the rebound effect to stopping expansion plate 7 so that after gate 3 is lifted,
Spring 6, which is upspring, stops expansion plate 7, and then ensure that the barrier such as the floating object such as trees or stone will not when opening a sluice gate and drawing out some water
Taken to pocket floor by high-velocity flow or be flushed in lock groove 8 and block.
It is described above to be merely exemplary for the utility model, and nonrestrictive, those of ordinary skill in the art
Understand, in the case where not departing from the spirit and scope that appended claims are limited, many modifications can be made, change or wait
Effect, but fall within the scope of protection of the utility model.
