Abstract
The present invention discloses a device changing the circular motion into the reciprocating straight-line motion, and comprises a supporting seat driving a gun head to telescopically move, a driving nut arranged in the supporting seat, and a driving screw axle gotten through the driving nut and meshed with an inner screw thread in the driving center; wherein the inner screw thread is arranged in the center of the driving nut, driving teeth are arranged on the peripheral surface. An opening is arranged on the supporting seat, a cover is arranged on the opening, and a rotation stopping clipping plate is positioned in the cover and connected with the cover as a whole. When the cover is covered on the opening, the rotation stopping clipping plate on the cover can be meshed with the driving teeth on the peripheral surface of the driving nut to prevent the driving nut from driving along with the driving screw axle and being forced to make the straight-line motion. When the device is required to be manually operated, the cover can be taken down, and the driving nut is pulled by hands to make the device do the straight-line motion, thereby the manual function of the device is met. The present invention reliably realizes that the rotation movement is changed into the straight-line dynamic force through the alternating effect of two springs on the both sides of the driving nut, thereby ensuring the reliability of the telescopic dynamic force of the spraying head of an electric fire fighting gun.
Description
Technical field
The present invention relates to a kind of flexible automatically device that circular movement is changed into linear reciprocating motion of electronic fire-fighting monitor spray head that makes, be used for fire-fighting domain.
Background technique
At present, knownly be used to control will rotatablely moving of electronic fire-fighting monitor spray head fore and aft motion and change straight-line device into, its structural type has two kinds: first kind is that transmission by gear realizes rotatablely moving turning and is straight line motion, second kind is will rotatablely move by linkage mechanism to change straight line motion into, when this dual mode all can't be realized not having electricity or motor failure manually, the third is the motion of the motion drive steel ball of utilization transmission shaft, steel ball is realized rotatablely moving by mechanism's power of frictional force band moving linearly and is changed straight line motion into, this scheme depends on the highi degree of accuracy that part is made, break down easily, and the non-general means in back that break down can be repaired, common way is that entire mechanism is changed, thereby brings too high user cost.
Summary of the invention
Technical problem to be solved by this invention is to overcome known existing the problems referred to above, a kind of new device that circular movement is changed into linear reciprocating motion is disclosed, this device has designed two springs that all transmission nut can be close to drive screw, guarantee at preceding drive screw and transmission nut positive engagement when once moving to a drive screw and transmission nut and breaking away from the cooperation reversing motion, thereby realize that repeated multiple times changes the purpose of injection big gun head extending amount.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind ofly change circular movement the device of linear reciprocating motion into, it is characterized in that, comprising:
One is connected and drives the bearing of big gun head fore and aft motion with the big gun head;
One is installed in the transmission nut in the bearing, and the center of described transmission nut is provided with internal thread, and outer circumferential face is provided with driving cog; In bearing, be provided with spline clamp with described driving cog engagement;
One pass transmission nut and with the drive screw shaft of the internal thread at transmission center engagement.
Drive screw shaft is under motor and reducing gear drive and rotate like this, and since transmission nut owing under the restriction of stop tooth, can not rotate and be forced to moving linearly, thereby drive the big gun head moving linearly that is connected with bearing.
In general, when no electricity or motor failure, should adopt manual mode is to make spray head make flexible straight line motion, in order to make said apparatus also can reach manual purpose, on above-mentioned bearing, offer an opening, by fastening piece one dismountable lid is installed on opening, described spline clamp is positioned at lid and is connected as a single entity with lid.When covering on the opening on the bearing, the spline clamp that covers just can mesh with the driving cog on the transmission nut outer circumferential face, stops transmission nut to be forced to do straight line motion with the drive screw shaft transmission.When needs are manual, can take off lid, stir transmission nut with hand and make it moving linearly, thereby satisfy the manual function of installing.
In general, when spray head moved limit position, drive screw shaft can be threaded off with the internal thread of transmission nut, and at this moment transmission nut can not rotate with the rotation of drive screw shaft again, and drive screw shaft can dally.For the thread head that makes in the middle of the drive screw shaft one section thread section can be very approaching with the internal thread of transmission nut, when the drive screw shaft backward rotation, mesh with transmission nut apace, the present invention is with two springs and by check ring two back-up rings is installed on drive screw shaft at the two ends of drive screw shaft thread section, in the bi-side of transmission nut two plane sliding bearings are installed, two springs lay respectively between two back-up rings and the plane sliding bearing.
For spring, plane sliding bearing and snap ring being sealed in the lubricated environment, respectively be fixed with a guide cylinder in the bi-side of bearing, wherein offer on the guide cylinder of left side and hold the axis hole that drive screw shaft is stretched out, the two ends of drive screw shaft are slidably supported in two guide cylinders.
The transmission nut moving linearly that the spline clamp that the motor that rotates is covered by the drive screw shaft driving blocks transfers circular movement to linear reciprocating motion under the servo condition, thereby drives the big gun head moving linearly that is connected with bearing.When the thread section on the drive screw shaft and transmission nut axle mediated the engaging position, two springs all were in the minute-pressure state that contracts.When device moves to the thread section of drive screw shaft and transmission nut and throws off, drive screw shaft and transmission nut are in slipping state, the rotation of drive screw shaft no longer drives the transmission nut moving linearly, this moment, a spring was in free state, the spring of opposite side is in compressive state, and the spring of compression withstands transmission nut and makes it tightly to touch with the thread section of drive screw shaft.When the drive screw shaft backward rotation, transmission nut and drive screw be engagement fast under the active force of spring, and transmission nut is driven by drive screw shaft and makes reverse straight line motion, has realized the change of power direction.
The beneficial effect of patent of the present invention is: the reliable effect ground of taking turns of two springs by the transmission nut both sides is realized rotate (circumference) and is moved and change straight line power into, effect implement device by clamp electronic and manual, thus the reliability of the flexible power of electronic fire-fighting monitor spray head guaranteed.
