Technical field
The utility model relates to the building hoist technical field, especially relates to a kind of building hoist up-down drive system; The utility model also relates to a kind of building hoist.
Background technology
The present up-down drive system of building hoist commonly used generally adopts the drive form of motor drives worm and gear, and input shaft adopts flat key to connect; Inefficiency, energy consumption is high, and running stability is undesirable; A little less than the load-carrying capacity, be prone to produce great amount of heat energy, cause the Transmission wearing and tearing; The bearing rapid wear, phenomenons such as leakage of oil happen occasionally.Each cage generally needs three motor and speed reducer parallel connections to drive, and it is big to take up room, and has increased the deadweight of equipment, has improved energy consumption, has reduced stability.
The utility model content
In order to overcome the deficiency that the use of building hoist up-down drive system, inconvenient maintenance, transmission are not steadily in the prior art, energy consumption is high.On the one hand, the utility model provides the building hoist up-down drive system that a kind of compact conformation, driving efficiency are high, energy consumption is low, transmission is stable.
For solving the problems of the technologies described above, the building hoist up-down drive system that the utility model provides comprises electrical motor; Quincunx elastic coupling; Anchor ring envelope reductor, said anchor ring envelope reductor has intermeshing worm and gear, and worm screw is connected with said electric motor drive through said quincunx elastic coupling; Be set with transmission gear on the worm gear output shaft, said transmission gear is meshing with each other with the driving rack of building hoist and is connected.
Further, the anchor ring envelope reductor of building hoist up-down drive system also is provided with at least one rolling backgear, and said rolling backgear is positioned at the opposite side that said driving rack has tooth, and can on said driving rack, roll.
On the other hand, the utility model also provides a kind of building hoist, and the building hoist that provides comprises at least one cage, and said cage has at least one up-down drive system, and said up-down drive system has electrical motor; Quincunx elastic coupling; Anchor ring envelope reductor, said anchor ring envelope reductor has intermeshing worm and gear, and worm screw is connected with said electric motor drive through said quincunx elastic coupling; Be set with transmission gear on the worm gear output shaft, said transmission gear is meshing with each other with the driving rack of building hoist and is connected; Said anchor ring envelope reductor also is provided with at least one rolling backgear, and said rolling backgear is positioned at the opposite side that said driving rack has tooth, and can on said driving rack, roll.
Preferably, the cage of building hoist is two, is symmetrically located at the both sides of the guide rail bracket of building hoist.
Preferably, on each cage of building hoist, have the two cover up-down drive systems that are arrangement up and down.
The utility model has following beneficial effect: utilize quincunx elastic coupling that electrical motor is connected with anchor ring envelope reductor, can compensate the relativity shift of diaxon, realize vibration reduction and cushioning; Improve driving efficiency, cut down the consumption of energy.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, constitutes the application's a part, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of embodiment building hoist up-down drive system;
Fig. 2 installs an example structure scheme drawing of up-down drive system for the building hoist cage.
The specific embodiment
Building hoist up-down drive system as shown in Figure 1, electrical motor 3 is in transmission connection with anchor ring envelope reductor 10 through quincunx elastic coupling 9.Anchor ring envelope reductor 10 has intermeshing worm and gear; Worm screw is in transmission connection with electrical motor 3 through quincunx elastic coupling 9; Be set with transmission gear 5 on the worm gear output shaft, transmission gear 5 is meshing with each other with the driving rack 2 (seeing also Fig. 2) of building hoist and is connected; Anchor ring envelope reductor 10 also is provided with a rolling backgear 4; Rolling backgear 4 is positioned at the opposite side that said driving rack 2 (seeing also Fig. 2) has tooth, and can on said driving rack 2, roll, and rolling backgear 4 is follower rollers; When the up-down drive system moves on driving rack 2; Produce friction drag between rolling backgear 4 and the driving rack 2, drive rolling backgear 4 through friction force and roll, thereby reduce friction.
Building hoist as shown in Figure 2; Cage can move up and down along a plurality of single roller 7 on the transmission vehicle frame column 1 that is installed in building hoist; On cage, have the two cover up-down drive systems that are arrangement up and down, the up-down drive system is entrusted 8 through motor and is fixed on the cage, and the transmission gear 5 of suit is meshing with each other with the driving rack 2 of building hoist on the worm gear output shaft; Rolling backgear 4 is positioned at the opposite side that driving rack 2 has tooth; And can on said driving rack, roll, transmission gear 5 and rolling backgear 4 are clamped in the both sides of driving rack 2 relatively, can avoid driving rack 2 to produce distortion in the course of the work.Through regulating the motor speed of two cover up-down drive systems, make its synchronized operation during work,, can realize the rising or the decline of cage motion through the rotating of switch motor.
The above is merely the preferred embodiment of the utility model, and limits the utility model never in any form, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit and principle that the utility model claims disclose, the modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
