Description
Affiliated technical field
The utility model relates to screw rod and opens and closes the descending clamping stagnation automatic shutdown protection of gate warning device.
Background technology
Middle-size and small-size hydraulic engineering plane gate generally adopts the screw open-close machine group.In running, the floating thing of upper river, half suspension often flows to lock chamber with current, and clamping stagnation is obstructed when causing gate descending.Because clamping stagnation position, the uncertainty of time, operating personnel are difficult in time find and handle, thereby the damage of opening and closing device and member take place easily.Wherein contingent damage type has following several: the one, and the nut stripped thread, malfunctioning when opening and closing once more, the door incident may take place to weigh down; The 2nd, headstock gear base top is bad; The 3rd, bent screws is used worn nut for a long time, damages bearing, need keep in repair or change screw rod when serious; The 4th, bad gate of top or headstock gear spandrel girder etc.
Worm-type open-close machine is made up of members such as motor, coupling arrangement, the big pinion of taper (or worm and wormwheel), nut, bearing and body fuselages.Rotated by the motor drives bevel pinion during operation, bevel pinion drives big angular wheel (or worm screw drives worm gear) again and rotates, and the nut that is fixed on the big angular wheel (or worm gear) makes screw rod make rectilinear motion up and down, thereby finishes the lifting process of gate.When the gate clamping stagnation, motor still rotates and continues gives the screw rod downward pressure by nut, behind the gate clamping stagnation this equal and opposite in direction, direction opposite reaction are passed to nut by screw rod, direction upwards, because headstock gear is fixed on the spandrel girder, can't move upward, promptly be equivalent to closing gate and still continue this situation of barrier gate on earth the time.
Summary of the invention
The purpose of this utility model is: provide a kind of screw rod to open and close the descending clamping stagnation automatic shutdown protection of gate warning device; behind the gate clamping stagnation, allow the headstock gear fine motion that makes progress; outage is simultaneously shut down; ensure the headstock gear safe operation; avoid destruction equipment, realize sluice Long-distance Control, unmanned, comprehensive automation management.
Technical solution of the present utility model is: utilize spring to can be used for characteristics such as buffering, damping, controlled motion, dynamometry, with headstock gear with non-resilient the connection change resilient connection between the spandrel girder, make it in gate decline process, have certain pressure and keep the stable of equipment, the leeway of rising is arranged when the gate clamping stagnation.Device is by compression spring, top board, lower platen, backstay, the moving disconnection closed, the moving pass of running jointly, the adjusting bolt is formed, the headstock gear bolt of lower base that has extended is with top board, lower platen is fixed on the headstock gear base through the compression spring spacer is liftoff, be with compression spring on the bolt of lower base between top board and the lower platen, backstay connects top board and lower platen, the moving Guan Hedong of disconnection runs jointly to close and is fixedly connected on the lower platen, corresponding respectively moving the running jointly of the adjusting bolt that is connected top board closed and moving the disconnection closed, moving disconnection is closed to be connected in the control circuit and is connected with the descending limit switch of gate, moving related device taking alarm or the terminal device run jointly.
When the gate clamping stagnation; the headstock gear base drives lower platen and moves upward; thereby the compression spring shortens the distance between the lower platen; simultaneously, the moving Guan Yudong that runs jointly disconnects and closing along with lower platen fortune fortune upwards, regulates bolt and presses the moving Guan Hedong of disconnection and run jointly to close and make its running; the moving disconnection closed circuit disconnection when moving; coil losing electricity, motor main line disconnect shuts down, and moving running jointly realized automatic warning function when closing action.
The utility model is simple in structure, and is with low cost, easy to make, can be used for the middle-size and small-size sluice of worm-type open-close machine of artificial keying, electronic keying, remote automation control.
Description of drawings
Fig. 1 is the worm-type open-close machine organigram
Fig. 2 is the utility model structural representation
Among the figure: 1 headstock gear base, 2 lower platens, 3 top boards, 4 backstays, 5,6 are regulated bolt, 7 headstock gear bolts of lower base, 8 compression springs, 9 moving pass, the 10 moving passes that disconnect run jointly.
The specific embodiment
As shown in Figure 2, device is by compression spring 8, top board 3, lower platen 2, backstay 4, regulate bolt 5,6, the moving disconnection closes 10, moving running jointly closed 9 compositions, the headstock gear bolt of lower base 7 that has extended is with top board 3, lower platen 2 is fixed on the headstock gear base 1 through compression spring 8 spacers are liftoff, be with compression spring 8 on the bolt of lower base 7 between top board 3 and the lower platen 2, backstay 4 connects top board 3 and lower platen 2, moving disconnection pass 10 is fixedly connected on the lower platen 2 with the moving pass 9 of running jointly, be connected the adjusting bolt 5 on the top board 3, the 6 corresponding respectively moving passes 9 of running jointly close 10 with moving the disconnection, moving disconnection pass 10 is connected in the control circuit connects with the descending limit switch of gate, and the moving pass 9 of running jointly connects alarm or terminal device.
When gate close the Men Liwei negative value time, illustrate that gate relies on deadweight to close, do not need spring that base is made plus-pressure, during installation, the height of spring is controlled in the free height and working depth of spring.When gate close Men Liwei on the occasion of the time, illustrate that gate needs headstock gear to impose downforce, when tightening the base nut with the Height Adjustment of spring working depth value to spring, if gate to close a power bigger, every bolt of headstock gear base can be joined 2 or 3 compression springs.In order to make the headstock gear base stressed even, device plays a role, and the control of spring highly wants consistent when tightening the base nut.
