Abstract
The utility model discloses a gate lifting mechanism, comprising a supporting seat, a gate supporting pillar, and a lifting device disposed on the supporting seat for bearing the gate supporting pillar. For improvement, the lifting device comprises a casing pipe connected with the gate supporting pillar, a worm gear and a worm matched with each other, a driving shaft connected with the worm, and a lifting screw rod connected with the worm gear, wherein the casing pipe is provided with a locating barrel inside; and the lifting screw rod is matched with the locating barrel. The lifting device drives a gate to ascend and descend through the transmission of the worm gear and the worm, and, with the self-locking function, the worm gear and the worm prevent the gate from dropping owing to gravity during the ascending and descending. The gate lifting mechanism realizes reliable and safe location and various states of the lift gate.
Description
Technical field
The utility model relates to a kind of elevating mechanism.
Background technology
The overhead door that is used for important storage repository or important base; Main up-down through assembly pulley or other elevating mechanism control gates; Because these local door quality of using are bigger, and these mechanism's ubiquities, in the lifting process; Door can't be located, and promptly door can't keep a certain state in lifting process.The door that quality is bigger all has the possibility of downslide at any time, causes personnel operation inconvenient, has potential safety hazard, can't adapt to multi-purpose needs.
Summary of the invention
The utility model is for solving the problem that prior art in use exists, provide a kind of use the location convenient, elevating mechanism.
The technical scheme that the utility model solves existing issue is: a kind of elevating mechanism; Comprise supporting base, door support column, be arranged at supporting base, carry the elevating mechanism of door support column; Improvement as the utility model; Described elevating mechanism comprises and the sleeve pipe that is connected of door support column, the worm and gear that cooperatively interacts, the driving shaft that is connected with worm screw, and the lifting screw that is connected with worm gear is provided with in the sleeve pipe and locatees swivel nut, described lifting screw and locate swivel nut and match.
As the further improvement of the utility model, be provided with the guide pipe that is fixed on the supporting base between described sleeve pipe and the location swivel nut.
As the further improvement of the utility model, described guide pipe is provided with stopper slot, is bolted with the stop screw that cooperates with stopper slot on the sleeve pipe.
The utility model compared with prior art, its beneficial effect is to go up and down through worm and gear transmission driving gate at elevating mechanism, by the back locking function of worm and gear, in the door lifting process, can not descend because of the gravity of door self.This product uses locatees reliable, safety, can realize the various states of overhead door.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is that Fig. 1 elevating mechanism A-A is to zoomed-in view.
The specific embodiment
Referring to Fig. 1-2, this case study on implementation comprises supporting base 1, door support column 2, be arranged at supporting base 1, carry the elevating mechanism of door support column 2.Elevating mechanism comprises and the sleeve pipe 3 that is connected of door support column 2, the worm gear 31 that cooperatively interacts, worm screw 32, the driving shaft 11 that is connected with worm screw 31; The lifting screw 12 that is connected with worm gear 32 is provided with location swivel nut 4, lifting screw 12 and locatees swivel nut 4 and match in the sleeve pipe 3.
Door for increasing the stability of sleeve pipe 3, is provided with the guide pipe 41 that is fixed on the supporting base 1 between sleeve pipe 3 and the location swivel nut 4 in lifting process.Wherein, guide pipe 41 is provided with stopper slot 42, is bolted with the stop screw 33 that cooperates with stopper slot 42 on the sleeve pipe 3, prevents a process of rising or falling, lifting screw 12 and location swivel nut 4 slippages.
