Abstract
Provided is an electric door machine head base, relating to a modified structure of an electric door machine head base. The base includes a base body, wheel transmission columns, wheels and a sprocket wheels; the left and right sides of the base are respectively provided with an inner support beam and an outer support beam; the inner support beam and the outer support beam at the two sides are respectively provided with a row of wheel transmission columns, a wheel is fixedly arranged at the external end of each wheel transmission column to form a walking wheel mechanism. The two rows of wheels are arranged in a straight line along the longitudinal direction at the two sides of the base; and the base further includes gears and transmission gears; every two longitudinally adjacent walking wheel mechanisms are combined into one group, the two wheel transmission columns of each group of walking wheel mechanisms are respectively fixedly provided with a gear, a transmission gear is arranged between the two gears of each group, the transmission gear is engaged with the two gears, the rotating shafts of the transmission gears are arranged on the outer support beam; and each group of wheel transmission columns is provided with a sprocket wheel. The base provided solves the problems that an electric door in the prior art is unstable in the process of running and is high in noise, as well as the electric door machine head base in the prior art is easy to damage.
Description
Technical field
The utility model relates to the improvement structure to the electric door machine head base.
Background technology
Existing electric door machine head base adopts chain drive, and not steady in the electric door operation process, noise is big, and the electric door machine head base is fragile.In addition, existing electric door base two row's wheels are installed power transmission shaft respectively, and each row's power transmission shaft is installed on two brace summers on the base, and this structure makes the width dimensions of base big.
The utility model content
The purpose of this utility model provides a kind of electric door machine head base, and the utility model has solved in the existing electric door operation process not steady, and noise is big, and the flimsy problem of electric door machine head base.
Electric door machine head base of the present utility model comprises that base 1, wheel take off post 2, wheel 3 and sprocket wheel 7; A medial support beam 1-1 and an outside brace summer 1-2 are arranged in base 1 left and right sides; One row's wheel respectively is installed on the medial support beam 1-1 of both sides and outside brace summer 1-2 takes off post 2, take off post 2 outer end of each wheel is installed with a wheel 3 and constitutes a road wheel mechanism, and two row's wheels 3 longitudinally are word order in base 1 both sides; Also comprise gear 4 and travelling gear 5; Vertically adjacent per two road wheel mechanisms form one group, two wheels of every group of road wheel mechanism take off post on 2, and each fixingly respectively is equipped with a gear 4, between two gears 4 of every group a travelling gear 5 is arranged, travelling gear 5 and two gear 4 engagements, the rotating shaft of travelling gear 5 is installed on the brace summer 1-2 of the outside; Take off post at each group wheel and a sprocket wheel 7 to be installed on 2.
Electric door machine head base of the present utility model by gear drive, has replaced chain drive before between wheel and the wheel, and it is stable that gear drive has operation process, and noise is little, non-damageable advantage.Two inboard beams in the middle of the utility model base can be according to client's needs cancellation, and the relative wheel in both sides adopts a wheel to take off post.Cost of production is reduced, and the base size reduces, and operational effect is constant.
Description of drawings
Fig. 1 is the utility model embodiment one structural representation;
Fig. 2 is the utility model embodiment two structural representations;
Fig. 3 is that the A of Fig. 1 is to view.
Symbol description among the figure: base 1, medial support beam 1-1, outside brace summer 1-2, wheel take off post 2, wheel 3, gear 4, travelling gear 5, bearing support 6, sprocket wheel 7.
The specific embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the utility model is done detailed explanation.
Embodiment one
Consult Fig. 1-Fig. 3, the electric door machine head base comprises that base 1, wheel take off post 2, wheel 3 and sprocket wheel 7; A medial support beam 1-1 and an outside brace summer 1-2 are arranged in base 1 left and right sides; One row's wheel respectively is installed on the medial support beam 1-1 of both sides and outside brace summer 1-2 takes off post 2, take off post 2 outer end of each wheel is installed with a wheel 3 and constitutes a road wheel mechanism, and two row's wheels 3 longitudinally are word order in base 1 both sides; Also comprise gear 4 and travelling gear 5; Vertically adjacent per two road wheel mechanisms form one group, two wheels of every group of road wheel mechanism take off post on 2, and each fixingly respectively is equipped with a gear 4, between two gears 4 of every group a travelling gear 5 is arranged, travelling gear 5 and two gear 4 engagements, the rotating shaft of travelling gear 5 is installed on the brace summer 1-2 of the outside; Take off post at each group wheel and a sprocket wheel 7 to be installed on 2.Wheel take off post 2 and the rotating shaft of travelling gear 5 be installed on the bearing support 6 on the brace summer 1-2 of the outside.
Embodiment two
Consult Fig. 2, the difference of present embodiment and embodiment one is: the medial support beam 1-1 on the base 1 is not set, and it 2 is an integral shaft structure that the relative wheel of base 1 both sides takes off post.
Above embodiment is the more preferably specific embodiment a kind of of the utility model, and the common variation that those skilled in the art carry out in the technical program scope and replacing should be included in the protection domain of the present utility model.
