Abstract
The utility model discloses a door lifting mechanism, which comprises a power device, a reversing device and a gear and rack lifting mechanism. Racks of the gear and rack lifting mechanism are fixed to two sides of a door, gears of the gear and rack lifting mechanism are fixed onto two parallel synchronous rotary shafts disposed on the two sides of the door, the gears are meshed with the racks, the power device is in transmission connection with the reversing device, the reversing device is provided with at least two mutually parallel reversing gear shafts, each of the two reversing gear shafts is respectively in transmission connection with a different synchronous rotary shaft chain, and rotation directions of the two reversing gear shafts are opposite to each other. The door lifting mechanism solves the problem that a plurality of doors cannot ascend or descend synchronously when an existing door lifting mechanism is used for lifting the doors. The door lifting mechanism is mainly used for industrial cleaning machines and has the advantage that a plurality of doors can ascend and descend synchronously by the aid of the door lifting mechanism.
Description
Technical field
The utility model relates to overhead door, particularly the door elevating mechanism of overhead door.
Background technology
Existing door elevating mechanism has a variety of, but these elevating mechanisms are all to single door design, when these elevating mechanisms are used for a plurality of up-down, will occur a plurality of can not synchronization lifting problem.
The utility model content
The purpose of the utility model provides a kind of elevating mechanism, when being used for a plurality of up-down to solve an existing door elevating mechanism, and the problem that a plurality of doors can not synchronization lifting.
The purpose of the utility model realizes through following technical scheme:
A kind of elevating mechanism; Comprise power set, reversing arrangement and rack-and-pinion elevating mechanism; The tooth bar of said rack-and-pinion elevating mechanism is fixed on the both sides of door, and the gear of said rack-and-pinion elevating mechanism is fixed on two parallel synchronous rotating shafts that are arranged at a both sides, said wheel and rack engagement; Said power set and reversing arrangement are in transmission connection; Said reversing arrangement has the commutating tooth wheel shaft that is parallel to each other with two at least, and each is connected the direction of rotation of said two commutating tooth wheel shafts with a different synchronization rotating shaft chain drive said two commutating tooth wheel shafts.
The gear parts of said commutating tooth wheel shaft places in the gear-box; Wherein a tumbler gear shaft extension goes out on the outer part of gear-box duplicate sprocket is installed; This duplicate sprocket respectively with the power set output shaft on sprocket wheel be in transmission connection with the sprocket chain that is arranged on wherein on the synchronous rotating shaft, be provided with tightener sprocket between another root commutating tooth wheel shaft and another root synchronous rotating shaft.
Be arranged between the said synchronous rotating shaft of the same side and connect through Hooks coupling universal coupling.
The beneficial effect of the utility model is: can realize a plurality of synchronization lifting.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is the structural representation of the door elevating mechanism of the utility model embodiment.
Among the figure: 1, power set; 2, tooth bar; 3, gear; 4, synchronous rotating shaft; 5, commutating tooth wheel shaft; 6, gear-box; 7, duplicate sprocket; 8, sprocket wheel; 9, tightener sprocket; 10, Hooks coupling universal coupling; 11, door.
The specific embodiment
As shown in Figure 1; The door elevating mechanism of present embodiment comprises power set 1, reversing arrangement and rack-and-pinion elevating mechanism, and the tooth bar 2 of said rack-and-pinion elevating mechanism is fixed on the both sides of door 11; The gear 3 of said rack-and-pinion elevating mechanism is fixed on two parallel synchronous rotating shafts 4 that are arranged at door 11 both sides; Said gear 3 and tooth bar 2 engagements, said power set 1 are connected with reversing arrangement chain drive, and said reversing arrangement has the commutating tooth wheel shaft 5 that is parallel to each other with two at least; Said two commutating tooth wheel shafts 5 respectively are connected the direction of rotation of said two commutating tooth wheel shafts 5 with a different synchronization rotating shaft 4 chain drive.
The mode that the power set 1 and the reversing arrangement of the utility model is in transmission connection also can adopt gear drive to be connected; As on the power output shaft of power set 1, gear being installed; With this gear and the wherein gear parts engagement of a commutating tooth wheel shaft 5, can satisfy power set 1 of the utility model and the requirement that reversing arrangement is in transmission connection equally then.
Particularly point out, the commutating tooth wheel shaft 5 of the utility model both can be whole gear shaft, and cogged axle also is installed.
The gear parts of said commutating tooth wheel shaft 5 places in the gear-box 6; Wherein a commutating tooth wheel shaft 5 stretches out on the part outside the gear-box 6 duplicate sprocket 7 is installed; This duplicate sprocket 7 respectively with power set 1 output shaft on sprocket wheel 8 be connected with sprocket wheel 8 chain drive on being arranged on wherein a synchronous rotating shaft 4, another root commutating tooth wheel shaft 5 and 4 of another root synchronous rotating shafts are provided with tightener sprocket 9.
In the time of a plurality of, synchronous rotating shaft 4 needs bigger length usually, for ease of making, usually synchronous rotating shaft is made several sections, and at this moment, with a cover power reversing arrangement, 4 of said synchronous rotating shafts that are arranged on the same side pass through Hooks coupling universal coupling 10 and connect for only.
The operating principle of the utility model is: power set provide power; The commutating tooth wheel shaft output that the power that the reversing arrangement realization provides power set turns to two differences; Two commutating tooth wheel shafts respectively are connected with a different synchronization rotating shaft chain drive; Two synchronous rotating shafts drive several gears fixed thereon and rotate simultaneously, thereby drive the door that a plurality of both sides are provided with tooth bar simultaneously, realize the synchronization lifting of door.
The utility model is mainly used in industrial cleaning machine, has the advantage of the synchronization lifting that can realize a plurality of.
