On one hand, the overlength transmission mechanism with the supporting device enables the self gravity of the transmission main shaft to be delivered out to solve the problem that the overlength transmission mechanism bends due to dead load, on the other hand, a novel the overlength transmission mechanism is provided for practical requirements.
Description
Technical field
The utility model relates to a kind of overlength driving mechanism, especially, relates to a kind of overlength driving mechanism with support device.
Background technique
When movable smoke screen is a kind of fire because of the effect of thalposis (heat fire detector), cigarette sense (smoke fire detector) or other control apparatus sagging smoke screen automatically.In order to satisfy the design requirement of construction market, constantly require production longspan smoke screen.But the longspan smoke screen needs the driving mechanism of longspan.And the transmission shaft span of the driving mechanism of longspan is big, again owing to its deadweight reason, can cause the transmission shaft of longspan serious bending deflection to occur.In the existing technology on the one hand the driving mechanism of little span can not satisfy the demand of existing market, thereby the longspan driving mechanism does not have corresponding support device to make the bending that deforms of the transmission shaft of longspan driving mechanism on the other hand.Therefore, there is a kind of demand in the reality, thereby can realizes the longspan slitless connection and solve the diastrophic situation of transmission shaft overlength transmission support device.
The model utility content
The purpose of the utility model is to overcome the shortcoming of existing technology, discloses a kind of overlength driving mechanism with support device, can solve the overlength driving mechanism because of deadweight produces diastrophic problem.
The utility model discloses a kind of overlength driving mechanism, comprising: transmission main shaft with support device; The auxilliary axle of transmission; Several support angle bar, and it is positioned at the same side of the auxilliary axle of said transmission and parallel to each other, and the said end that several support angle bar is fixing with the auxilliary axle welding of said transmission respectively; Several support pulley, and it has and said strut angle iron phase quantity together, and said several support pulleys are separately fixed on said several support angle bar said transmission main shaft and said several support pulley sliding contacts.
Preferably, the overlength driving mechanism with support device of the utility model, the auxilliary axle of said transmission is formed by connecting through coupling shaft for the auxilliary axle of several transmissions.
Preferably, the overlength driving mechanism with support device of the utility model, said each coupling shaft also are connected with bearing respectively in its both sides, thereby the auxilliary axle of two adjacent transmissions is linked together.
Preferably, the overlength driving mechanism with support device of the utility model, the said end that several support angle bar is connected and fixed through weld bolt at said coupling shaft place with the auxilliary axle of said transmission respectively.
Preferably, the overlength driving mechanism with support device of the utility model, said support angle bar be formed with several angle with a fixing end and the horizontal plane of the auxilliary axle welding of said transmission.
Preferably, the overlength driving mechanism with support device of the utility model, the auxilliary axle of said transmission main shaft and said transmission is parallel to each other.
Preferably, the overlength driving mechanism with support device of the utility model, said several support angle bar are all orthogonal with the auxilliary axle of said transmission.
The beneficial effect of the utility model is: thus the overlength driving mechanism with support device of the utility model has solved the overlength driving mechanism owing to conducting oneself with dignity former thereby producing diastrophic problem with passing from gravity of main drive shaft on the one hand, also for current demand a kind of novel overlength driving mechanism is provided on the other hand.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is a side view of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description, can implement according to this with reference to the specification literal to make those skilled in the art.
As depicted in figs. 1 and 2, a kind of overlength driving mechanism with support device of the utility model comprises: transmission main shaft 1; The auxilliary axle 2 of transmission; Several support angle bar 3, and it is positioned at the same side of the auxilliary axle 2 of said transmission and parallel to each other, and it is all orthogonal with the auxilliary axle of said transmission 2 that said several support angle bar 3, and the said end that several support angle bar 3 is fixed with auxilliary axle 2 welding of said transmission respectively; Several support pulley 5, and it has the quantity identical with said support angle bar 3, and said several support pulleys 5 and be separately fixed at said several and support on angle bar 3, and said transmission main shaft 1 supports pulley 5 sliding contacts with said several.
The overlength driving mechanism with support device of the utility model, the auxilliary axle 2 of said transmission is formed by connecting through coupling shaft 4 for the auxilliary axle of several transmissions.And each coupling shaft 4 also is connected with bearing respectively in its both sides, thereby the auxilliary axle of two adjacent transmissions is linked together.Thereby the said end that several support angle bar 3 is connected and fixed through welding or bolt at said coupling shaft place 4 with the auxilliary axle of said transmission 2 respectively.
The overlength driving mechanism with support device of the utility model, said support angle bar 3 be formed with several angle with a fixing end and the horizontal plane of auxilliary axle 2 welding of said transmission.
The overlength driving mechanism with support device of the utility model, said transmission main shaft 1 is parallel to each other with auxilliary 2 of said transmission.
During use, when main shaft 1 rotated, the auxilliary axle 2 and the support angle bar 3 of setting supported pulleys 5, were supported by 5 pairs of main shafts 1 of pulley again, thereby form several strong points (signal is only 3 among the figure) main shaft 1 were supported.When main shaft 1 is long; Cause the bent intermediate distortion by its action of gravity meeting; Yet support angle bar 3 in the device of the utility model and auxilliary axle 2 firm welding; 5 pairs of main shafts 1 of pulley support, so just the force of gravity of main shaft 1 self on the auxilliary axle 2, thereby solved main shaft 1 when long because of the diastrophic situation of conducting oneself with dignity.
Although the embodiment of the utility model is open as above; But it is not restricted to listed utilization in specification and the mode of execution; It can be applied to the field of various suitable the utility model fully, for being familiar with those skilled in the art, can easily realize other modification; Therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
