Description

A kind of electric gate valve

Technical field

This utility model is related to a kind of gate, especially relates to a kind of electric brake of warehouse logisticses and corn processing technique field Door.

Background technology

In prior art, in storage or corn manufacture field the flowing that gate carrys out control material, usual feelings are often used Electric gate valve is also the rotating for leaning on two travel switches to control reducing motor under condition, to realize the unlatching of electric gate valve and close Close；But sometimes travel switch can fail, when flashboard in place after reducing motor also operation, although have protection in electrical control, But reducing motor current spikes rise and also result in reducing motor damage, in addition operate by force also can be to screw rod and spiral shell for reducing motor The screw pair of mother set composition causes excessive wear.

Utility model content

The purpose of this utility model is to provide a kind of electric gate valve, overcomes problems of the prior art, can pass through Travel switch controls the rotating of reducing motor, realizes the on-off control of gate, the control to Flow of Goods and Materials is completed, while can The screw pair of screw rod is damaged when effectively preventing motor from operating by force.

For this purpose, the technical scheme that this utility model is provided is as follows：A kind of electric gate valve, including gate framework, are arranged on lock Flashboard and screw rod in door frame, gate frame mid portion arranges cut-off, and gap is left on cut-off；Flashboard passes through gap by gate frame The one side closed formation sluice gate of frame, coordinates on the gate framework of flashboard lower section both sides and is provided with the directive wheel for supporting flashboard, gate framework Inwall both sides are provided with travel switch；Flashboard lower section is provided with the Impactor being engaged with travel switch, the spiral shell on flashboard and screw rod Mother set is fixedly connected, and on gate framework reducing motor is provided with；Screw rod one end is connected with reducing motor output shaft, the screw rod other end It is connected with the rolling bearing units arranged on cut-off, screw flight section rear and front end portion is respectively kept with light bar segment, divides in two light bar segments Buffer spring is not set with, baffle plate is installed on the outside of two buffer springs.

When flashboard is in closure state, the contact that now Impactor depression stroke is switched, reducing motor stops, and nut Critical state of the set with screw rod in departing from；When starting gate, reducing motor is reversely rotated and drives screw rod rotation, nut sleeve edge Spiro rod length direction is moved, and nut sleeve is engaged under the impetus of buffer spring with screw rod, drives flashboard reverse movement；When touching During the contact of collision block depression stroke switch, reducing motor stops, and gate is fully opened, and realizes unlatching and the closure of gate；Work as row During journey switch failure, reducing motor is continued to run with due to cannot get signal, but now nut sleeve is complete with the screw thread on screw rod Complete to disengage, nut sleeve is at light bar segment, because screw rod two ends are provided with buffer spring and baffle plate, so nut sleeve will not take off Fall, screw rod can only dally；The beneficial effects of the utility model are：This utility model controls reducing motor by travel switch Rotating, realizes the on-off control of gate, completes the control to Flow of Goods and Materials, while when can effectively prevent motor from operating by force Damage the screw pair of screw rod.

As further improvement of the utility model, burden-guiding cone, burden-guiding cone and flashboard are provided between flashboard and gate framework Between angle be not less than 45 °；The beneficial effect of the technical scheme is, it is ensured that material can be smoothly flowed in mouth, be unlikely to It is stuck at sluice gate, affects the smoothness of knife switch.

Used as further improvement of the utility model, Impactor is arranged in inverted trapezoidal；The inclined-plane of the technical scheme inverted trapezoidal Primarily serve buffer-oriented effect, it is ensured that the accuracy and stability of knife switch.

Specific embodiment

As Figure 1-3, a kind of electric gate valve, including gate framework 1a, be arranged on 1a in gate framework flashboard 2a and Screw rod 9, is provided with burden-guiding cone 1b between flashboard 2a and gate framework 1a, angle is not less than 45 ° between burden-guiding cone 1b and flashboard 2a, lock Door frame 1a middle parts arrange cut-off, and cut-off is made up of two blocks of L-shaped steel 15, and gap is left on cut-off；Flashboard 2a passes through gap Jiang Zha Door frame 1a is one side closed to form sluice gate 14, coordinates on the gate framework 1a of flashboard 2a lower sections both sides and is provided with leading for support flashboard 2a To wheel 3, gate framework 1a inwalls both sides are provided with travel switch a11 and travel switch b12；Flashboard 2a lower sections are provided with opens with stroke The Impactor 2b that a11 and travel switch b12 is engaged is closed, Impactor 2b is arranged in inverted trapezoidal；Nut on flashboard 2a and screw rod 9 Set 8 is fixedly connected, and on gate framework 1a reducing motor 10 is provided with；The one end of screw rod 9 is connected with the output shaft of reducing motor 10, spiral shell The other end of bar 9 is connected with the rolling bearing units 4 arranged on cut-off, and the thread segment rear and front end portion of screw rod 9 is respectively kept with light bar segment 13, Buffer spring 6 is respectively installed with two light bar segments 13, the outside of two buffer springs 6 is provided with baffle plate 5.

During utility model works, when flashboard 2a is in closure state, now Impactor 2b depression strokes switch b12's Contact, reducing motor 10 stops, and nut sleeve 8 is located in light bar segment 13, its with screw rod 9 on critical shape of the screw thread in departing from State；When starting gate, reducing motor 10 is reversely rotated and drives screw rod 9 to rotate, impetus of the nut sleeve 8 in buffer spring 6 It is lower to engage with screw rod 9, flashboard 2a reverse movements are driven, when Impactor 2b depression strokes switch the contact of a11, reducing motor 10 Stop, gate is fully opened, so as to realize unlatching and the closure of gate；When travel switch fails, reducing motor 10 is due to obtaining Continue to run with less than signal, but now nut sleeve 8 is completely disengaged with the screw thread on screw rod 9, and nut sleeve 8 is in light bar segment 13 Place, because the two ends of screw rod 9 are provided with buffer spring 6 and baffle plate 5, so nut sleeve 8 will not fall off, screw rod 9 can only dally, will not Reducing motor 10 and screw pair are caused damage.

This utility model is not limited to above-described embodiment, disclosed in this utility model on the basis of technical scheme, this The technical staff in field is according to disclosed technology contents, it is not necessary to which performing creative labour just can be special to some of which technology Levy and make some replacements and deform, these are replaced and deform in protection domain of the present utility model.
