Description
Technical field
The utility model relates to lifter apparatus field, is specifically related to a kind of single suspension centre building hoist.
Background technology
In the last few years, along with the continuous quickening of economic construction paces, China's building engineering cause also achieves great progress, building hoist is as a kind of building engineering conventional machinery, play an important role in Practical Project, building hoist is again construction elevator for building, the manned of frequent use in building, loading construction machinery and equipment, be mainly used in high-rise building, bridge, the construction of chimney etc., construction elevator cage running part can be inhead type transmission, also can be built-in transmission, the driving device of existing driving upper set construction elevator is generally electrical motor and drives reductor, reductor driving gear wheel and rack engages, under the cooperation of guidance system, drive elevator up-and-down movement, the form that inhead type driving device and the connection of cage all adopt two suspension centre to be connected, suspension centre is distributed in the both sides of cage, when the load-carrying article in cage are placed lack of standardization, the situation of easy generation load over centre, at this moment the load acted on two suspension centres can not wait, different loads on two suspension centres produces different moment of flexure to driving device, two superimposed meetings of moment of flexure make the force-bearing situation of driving device become more severe, thus reduce the service life of driving device, therefore the building hoist designing a kind of novel single suspension centre is needed.
Summary of the invention
For above problem, the utility model provides a kind of single suspension centre building hoist.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of single suspension centre building hoist, it comprises gear frame, electrical motor and tooth bar, described electrical motor is arranged on gear frame, described electrical motor is connected with driven wheel, described driven wheel is connected with two carrier gears, described carrier gear diameter is greater than driven wheel, described carrier gear is connected to carrier gear with another by tooth bar, described electrical motor is provided with plum blossom plunging joint, described gear frame lower end is provided with suspension centre, described gear frame is provided with two guide wheels, described guide wheel flushes with suspension centre in the horizontal direction.
Further, described electrical motor is provided with reductor.
Further, described driven wheel and two carrier gears form an equicrural triangle and arrange.
Further, described tooth bar adopts spur rack, and its length is 1.2m-1.6m.
Further, described guide wheel comprises wheel body, wears axis hole and fixing collar, described in wear axis hole and be arranged on wheel body, described fixing collar is enclosed within to be worn on axis hole.
The beneficial effects of the utility model:
The utility model is overlapped with the carrier gear line of centres and standard knot center line of guide rail three line by the single suspension centre line of centers of setting, driving device can be made to be in minimum strained condition in theory, be connected owing to adopting single suspension centre between driving device with cage, whether eccentric respectively regardless of the load in cage, single suspension centre can only produce a downward application force under the application force of cage load, avoiding common double suspension centre transmission device of construction elevator because of load over centre reduces the situation in service life by two different moment combineds action cause load over centre moment excessive, in addition, driven wheel is engaged with tooth bar indirectly by carrier gear, carrier gear disperses stressed, effectively improve the service conditions of driving device, reduce Contact Stress of Gear, extend the service life of rack and pinion engagement system, thus improve its reliability.

Number in the figure is: 1-gear frame, 2-tooth bar, 3-carrier gear, 4-driven wheel, 5-electrical motor, 6-reductor, 7-plum blossom plunging joint, 8-suspension centre, 9-guide wheel, 10-wheel body, and 11-wears axis hole, 12-fixing collar.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, a kind of single suspension centre building hoist, it comprises gear frame 1, electrical motor 5 and tooth bar 2, described electrical motor 5 is arranged on gear frame 1, described electrical motor 5 is connected with driven wheel 4, described driven wheel 4 is connected with two carrier gears 3, described carrier gear 3 diameter is greater than driven wheel 4, described carrier gear 3 is connected to carrier gear 3 with another by tooth bar 2, described electrical motor 5 is provided with plum blossom plunging joint 7, described gear frame 1 lower end is provided with suspension centre 8, described gear frame 1 is provided with two guide wheels 9, described guide wheel 9 flushes with suspension centre 8 in the horizontal direction.
On above-described embodiment preferably, described electrical motor 5 is provided with reductor 6.
On above-described embodiment preferably, described driven wheel 4 and two carrier gears 3 form an equicrural triangle and arrange.
On above-described embodiment preferably, described tooth bar 2 adopts spur rack, and its length is 1.2m-1.6m.
, described guide wheel 9 comprises wheel body 10, wears axis hole 11 and fixing collar 12 on above-described embodiment preferably, described in wear axis hole 11 and be arranged on wheel body 10, described fixing collar 12 is enclosed within to be worn on axis hole 11.
Based on above-mentioned, the utility model is overlapped with the carrier gear line of centres and standard knot center line of guide rail three line by the single suspension centre line of centers of setting, driving device can be made to be in minimum strained condition in theory, be connected owing to adopting single suspension centre between driving device with cage, whether eccentric respectively regardless of the load in cage, single suspension centre can only produce a downward application force under the application force of cage load, avoiding common double suspension centre transmission device of construction elevator because of load over centre reduces the situation in service life by two different moment combineds action cause load over centre moment excessive, in addition, driven wheel is engaged with tooth bar indirectly by carrier gear, carrier gear disperses stressed, effectively improve the service conditions of driving device, reduce Contact Stress of Gear, extend the service life of rack and pinion engagement system, thus improve its reliability.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
