Abstract
Disclosed is a stirring transmission device with a self-lifting function. The stirring transmission device is capable of controlling the height of a stirring shaft automatically or manually, thereby realizing safety work and convenient maintenance of a stirrer. The stirring transmission device is positioned on a stirring container via a lower case body, and a motor drives a worm screw which drives a worm wheel. By the aid of the guider connected with the worm wheel, the worm wheel drives the stirring shaft, a lifting screw rod and a lifting screw nut through a bearing beam. A torque sensing device is mounted at the connecting position of the motor and the worm screw, the lifting screw nut is controlled by a braking device, and the torque sensing device transmits signals to the braking device to control rotating and stopping of the lifting screw nut according to changes of the size of the working torque of the stirring shaft, thereby controlling the stirring shaft at a proper working height.
Description
Technical field
The utility model is to stir transmission device, more specifically says so to have stirring transmission device from enhanced feature.
Background technology
In large-scale mixer. agitating device such as mud scraper, settling tank system, the operation torque that require the rotating speed of shaft low, to bear is big, rotating speed usually be per minute less than a commentaries on classics, operation torque can reach Newton meters up to ten thousand.And, because big alluvial in the stirred vessel than heavy material, make that the agitator rotation in the stirred vessel is difficult, to such an extent as to sharply rising, the shaft operation torque at agitator place causes the dead car phenomenon of stall, not only be affected equipment life, clear up stirred vessel alluvial and shaft simultaneously and restart also very difficult.
Summary of the invention
The utility model provides a kind of stirring transmission device that has from enhanced feature, it during design the selected torque critical value of shaft, operation torque is during less than the torque critical value, stir the transmission device operate as normal, deposit in stirred vessel too much, when agitator rotation difficulty caused operation torque greater than the torque critical value, shaft is lifting automatically, till operation torque was less than the torque critical value, at this moment agitator was in new position operate as normal.The stirring transmission device can also according to maintenance or need of work rises or the decline shaft arrives the appropriate location.
The technical scheme that its technical problem that solves the utility model adopts is: stir transmission device and be positioned on the stirred vessel by lower box, at first by the motor-driven worm screw, the worm drive worm gear, the lower flat bearing is installed below the worm gear and between the lower box, connect with guider above the worm gear and drive shaft by carrier bar again by guider, be manufactured with on the guide walls and allow spandrel girder strip fenestra in axial sliding, cooperate with sliding bearing between guider and the shaft, at motor and worm screw connection place torque sensing device is installed, upper end at shaft connects with the lifting screw mandrel by shaft coupling, promote on the screw mandrel and be equipped with hoisting nut, the upper plane bearing is installed between hoisting nut and the guider, and hoisting nut is controlled by brake apparatus.During operate as normal, hoisting nut is rotated with promoting screw mandrel, and when the shaft torque reached the torque critical value, torque sensing device was delivered to brake apparatus to signal and makes its work, no longer with promoting the screw mandrel rotation, the lifting screw mandrel begins to promote the drive shaft and promotes hoisting nut.When torque during less than the torque critical value, torque sensing device is delivered to brake apparatus to signal quits work it, and hoisting nut begins again to stir transmission device and still continue operate as normal with promoting the screw mandrel rotation.The position that to adjust shaft easily that turns to by brake apparatus and hoisting nut and lifting screw mandrel, be convenient to select the working depth and the maintenance of agitator, the lifting working region of shaft is by top LX19 travel switch and the restriction of bottom LX19 travel switch.
The beneficial effects of the utility model are, can be automatically or control the shaft height artificially, and realize the trouble free service of agitator and maintain easily, and the rotation of shaft and promoting is only finished by a motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the stirring transmission structures schematic diagram that has from enhanced feature.
Among the figure, 1. lower box, 2. lower flat bearing, 3. worm gear, 4. worm screw, 5. spandrel girder, 6. shaft coupling, 7. guider 8. promotes screw mandrel, 9. hoisting nut, 10. brake apparatus, 11. upper plane bearings, 12. top LX19 travel switch, 13, bottom LX19 travel switch, 14. sliding bearing, 15. shafts.
The specific embodiment
In Fig. 1, lower box (1) is installed and is positioned on the stirred vessel, at first by motor-driven worm screw (4), worm screw (4) drives worm gear (3), worm gear (3) drops on lower flat bearing (2) and goes up with lower box (1) support, and the guider (7) that connects with it during worm gear (3) rotation rotates thereupon, and guider (7) drives spandrel girder (5) rotation again, spandrel girder (5) is with shaft (15) all-in-one-piece to be installed, so shaft begins to rotate the agitator work that drives in the stirred vessel.Because torque sensing device has been installed at motor and worm screw connection place, when alluvial in the stirred vessel too much causes the shaft operation torque greater than the torque critical value, be reflected on the torque sensor in the linked system, torque sensor is delivered to brake apparatus (10) to signal and makes its work, hoisting nut (9) is no longer with promoting screw mandrel (8) rotation, screw mandrel (8) rises and drive shaft (15) rises so promote, at this moment the agitator in the stirred vessel descends with the operation torque that shaft (15) rising makes alluvial bring for shaft (15), and while hoisting nut (9) is applied to the axial force of carrying on the guider (7) by upper plane bearing (11).When operation torque drops to less than the torque critical value, torque sensing device is delivered to brake apparatus (10) to signal quits work it, hoisting nut (9) begins again with promoting screw mandrel (8) rotation, so agitator new height and position operate as normal in stirred vessel.Top LX19 travel switch (12) and bottom LX19 travel switch (13) are in order to the lifting working region of restriction shaft (15).By brake apparatus (10) and hoisting nut (9) and promote that turning to of screw mandrel (8) can be adjusted shaft (15) easily thus the position conveniently select the height cleaning stirred vessel of agitator and carry out agitator and safeguard.
Claims (2)
1. has stirring transmission device from enhanced feature, it is made up of lower box, worm screw, worm gear, guider, spandrel girder, shaft, worm screw is by driven by motor, it is characterized in that connecting with the lifting screw mandrel by shaft coupling in the upper end of shaft, promote on the screw mandrel and be equipped with hoisting nut, hoisting nut is controlled by brake apparatus.
2. according to the described stirring transmission device that has from enhanced feature of claim 1, it is characterized in that being manufactured with permission spandrel girder strip fenestra in axial sliding to the guide walls of shaft transferring power from worm gear.
