Abstract
The utility model discloses a single-track electric travelling crane, which comprises a machine frame, a motor, two driving roller wheels and two driven roller wheels, wherein the driving roller wheels and the driven roller wheels are respectively installed on a right bracket and a left bracket of the machine frame through roller wheel shafts; the single-track electric travelling crane is characterized in that the driving roller wheels are in transmission connection with the motor through an intermediate gear set; the intermediate gear set comprises a gear shaft and an intermediate gear; the gear shaft is connected with the motor through a deceleration box; all the driving roller wheels are arranged on two sides of the intermediate gear; furthermore, the intermediate gear is meshed with the gear shaft; and the driving roller wheels are meshed with the intermediate gear. According to the utility model, the two driving roller wheels are synchronously transmitted through the gear shaft and the intermediate gear of the gear set; therefore, the distance between the two driving roller wheels is enlarged, so that a support interval of the four roller wheels is enlarged; and the change range of a load centre is within the support interval.
Description
Technical field
The utility model relates to a kind of improvement invention of electric bicycle, particularly be single track electric bicycle in a kind of lifting equipment.
Background technology
Electric bicycle is a kind of rail-mounted operating unit, as the Horizontal Movement article.In the prior art, what be complementary with minisize electric hoist is small-sized single track electric bicycle, there are following three problems in existing small-sized single track electric bicycle: 1, the spacing between two driving rollers and two return idlers is little, make the center of gravity of load exceed the interval of bearing force, the scope that namely exceeds support causes driving to topple over; 2, the high and low position of roller can not be adjusted, and four rolling can not contact with guide rail simultaneously, only often occurs that three-wheel contacts with guide rail, thereby has dwindled the area of support, and is not steady during operation; 3, idler wheel surface is double curved surface, thereby roller and guide rail be to contact, thereby the pair roller wearing and tearing are large, cause guide rail surface to be worn into groove.
Summary of the invention
In view of the existing technical matters of background technology, technical problem to be solved in the utility model provides a kind of adjustable roller height, adds spacing between big roller, and reduces the single track electric bicycle to way rub.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: this kind single track electric bicycle, comprise frame, motor, driving roller and return idler, described driving roller and return idler have respectively two, described driving roller and return idler are installed in respectively on the right support and left socle of frame by roller shaft, it is characterized in that described driving roller is connected with motor-driven by the center tooth wheels, described center tooth wheels include gear wheel shaft and intermediate gear, described gear wheel shaft is connected with motor by drop-gear box, described driving roller distribute columns evenly is in the both sides of intermediate gear, and described intermediate gear and gear wheel shaft engagement, described driving roller and intermediate gear engagement.
Described return idler is connected with an end of roller shaft, and the other end of this roller shaft is arranged with eccentric bushing, and described roller shaft and eccentric bushing are installed on the left socle.
Described left socle is connected pipe link with right support and connects, and is arranged with spacer, left comer iron and right corner iron on the described pipe link.
Described spacer is divided into thick spacer and leptophragmata cover.
The idler wheel surface of described driving roller and return idler contacts with the guide rail upper thread, is provided with self-aligning ball bearing between described return idler and the roller shaft.
The utility model passes through gear wheel shaft and intermediate gear synchrodrive two driving rollers of gear cluster, thereby has enlarged the spacing between two driving rollers, has namely enlarged the support Interval of four rolling, and the mobility scale at proof load center is in support Interval.The utility model can be adjusted the height of return idler by rotating eccentric sleeve, four-wheel all can be contacted with guide rail, and the idler wheel surface of driving roller of the present utility model and return idler contacts with the guide rail upper thread, thereby driving is very steady, wearing and tearing to guide rail are little, longer service life, and the angle that described self-aligning ball bearing adapts to a certain degree return idler changes, make the idler wheel surface of return idler consistent with the angle of guide pass, thereby guarantee the rolling of line contact.Described left comer iron and right corner iron rule are used for installing electric block; Thick spacer and leptophragmata cover then is used for adjusting the spacing between driving roller and the passive roller on the described pipe link.
Description of drawings
Further describe principle of work of the present utility model and details thereof below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is along the cutaway view of Figure 1A-A direction.
The specific embodiment
With reference to accompanying drawing, this kind single track electric bicycle, comprise frame, motor 7, driving roller 4 and return idler 3, described driving roller 4 and return idler 3 have respectively two, and the idler wheel surface 14 of described driving roller 4 and return idler 3 is circular conical surface, the angle of its inclination is consistent with guide pass 17, and idler wheel surface 14 contacts with guide pass 17 lines.Described driving roller 4 and return idler 3 are installed in respectively on the right support 5 and left socle 1 of frame by roller shaft 2, be provided with deep groove ball bearing 18 between described driving roller 4 and the roller shaft 2, be provided with self-aligning ball bearing 13 between described return idler 3 and the roller shaft 2, and be arranged with eccentric bushing 12 on this roller shaft 2, described roller shaft 2 and eccentric bushing 12 are installed on the left socle 1, described aligning ball journal 13 holds the angle that return idler 3 is adapted to a certain degree to be changed, make the rolling surface 14 of roller consistent with the angle of guide pass 17, thereby guarantee the rolling of line contact, 12 height that are used for adjusting return idler 3 of described eccentric bushing, be the height that rotating eccentric sleeve 12 just can be adjusted return idler 3, adjust very convenient.Described driving roller 4 is in transmission connection with motor 7 by center tooth wheels and drop-gear box 6, and described left socle 1 is connected with right support by pipe link 8 connections, is arranged with thick spacer 10, leptophragmata cover, left comer iron 9 and right corner iron 11 on the described pipe link 8.Described center tooth wheels include gear wheel shaft 16 and intermediate gear 15, described gear wheel shaft 16 is connected with motor 7 by drop-gear box 6, intermediate gear described in the present embodiment has two, described intermediate gear 15 and driving roller were listed in the both sides of gear wheel shaft 16 in 4 minutes, and described intermediate gear 15 and gear wheel shaft 16 engagements, described driving roller 4 and intermediate gear 15 engagements, gear wheel shaft 16 is by intermediate gear 15 synchrodrive driving rollers 4, enlarged the spacing of two driving rollers 4, namely enlarged the support Interval of four rolling, the mobility scale at proof load center in support Interval, traffic safety, steadily.
