Abstract
The utility model discloses a single column building hoist with a speed reducer. The single column building hoist with the speed reducer comprises a suspension cage used for loading people or goods and a guide rail bracket formed by standard knots. A speed reducer is arranged at the top of the suspension cage and provided with a dual output gear which is meshed with a gear rack on the guide rail bracket. The speed reducer is further provided with a box body, a follow-up gear and a reducing gear, wherein the follow-up gear and the reducing gear are arranged inside the box body. The follow-up gear is meshed with the speed reducing gear. The guide rail bracket formed by the standard knots is provided with a double rack which is meshed with the dual output gear of the speed reducer. The single column building hoist with the speed reducer is capable of enabling braking force to drive dispersedly, reducing stress concentration, and improving brakeload, and suitable for a single column building hoist with a large capacity and a large load.
Description
Technical field
The utility model relates to the building hoist technical field, is specifically related to a kind of single-column building hoist with reductor.
Background technology
High speed development along with national economy, building hoist begins bringing into play huge effect at increasing building field, elevator client both domestic and external is also more and more higher for the operating needs of elevator, a lot of skyscrapers and factory building need the larger building hoist of load carrying ability when transporting building materials and goods, and need to stablize, running velocity is fast, building hoist with low cost and safety performance is high, existing building hoist falls for preventing cage, employing reductor and the tooth bar of guide rail bracket are meshed to make cage to slow down and stop, but existing reductor output gear is individual gears, carry out again speed limit after the tooth bar engagement of individual gears and standard knot, this ways of deceleration is because of the power central driving, can not bear the large cage of load-carrying, velocity limiter is less by the brake load that the monodentate reductor bears.Therefore, for the large single-column building hoist of load carrying ability, obvious this reductor can not improve brake load, has limited the load-carrying weight of cage.
The utility model content
The utility model embodiment technical matters to be solved is, a kind of building hoist with reductor is provided, and can make braking force disperse transmission, reduces stress and concentrates, and improves brake load, is applicable to the single-column building hoist of large capacity, heavy－duty.
In order to solve the problems of the technologies described above, the utility model provides a kind of building hoist with reductor, comprise for the cage that loads people or goods, the guide rail bracket that is formed by standard knot, on the cage top reductor is installed, described reductor is provided with the dual output gear, and described reductor dual output gear is meshed with the guide rail bracket upper rack, the number of teeth of described output gear is 12, and modulus is 8.
Wherein, described reductor also comprises casing, phantom gear and reducing gear, and described phantom gear and reducing gear place in the casing, and described phantom gear and reducing gear are meshed.
Wherein, the described phantom gear number of teeth is 17, and modulus is 8, and the described reducing gear number of teeth is 21, and modulus is 8.
Wherein, the described guide rail bracket that is comprised of standard knot is provided with double rack, and the dual output gear of described reductor is engagement corresponding to tooth bar respectively.
Wherein, described box body of speed reducer is formed by Plate Welding.
A kind of single-column building hoist with reductor that the utility model provides, the mouth of reductor is exported by the dual output gear, thereby exert all one's strength the dispersion transmission, reducing stress concentrates, guarantee to bear larger power, single-column construction elevator cage velocity limiter when falling improves by the specified brake load of reductor simultaneously, uses through test in the operation of single-column building hoist, and velocity limiter improves 1.4 times of specified brake loads by this deceleration function.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the below will do to introduce simply to the accompanying drawing of required use among the embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of single-column building hoist speed reducer structure figure with reductor that the utility model provides;
Fig. 2 is a kind of single-column building hoist reductor inner structure front view with reductor that the utility model provides.
The specific embodiment
A kind of single-column building hoist with reductor that the utility model provides, mouth is by the dual output gear power output of reductor, thereby make braking force disperse transmission, reducing stress concentrates, velocity limiter can improve specified brake load by this retarder, is applicable to the single-column building hoist of large capacity, heavy－duty.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, Fig. 2, a kind of a kind of single-column building hoist reductor inner structure front view with reductor that provides with single-column building hoist speed reducer structure figure and the utility model of reductor that provides for the utility model, reductor 1 comprises casing 2, phantom gear 3 and reducing gear 4, described casing 2 is formed by the thickening Plate Welding, described phantom gear 3 and reducing gear 4 place in the casing 2, the number of teeth of described phantom gear 3 is 17, modulus is 8, the number of teeth of described reducing gear 4 is 21, modulus is 8, described phantom gear 3 and reducing gear 4 are intermeshing, described reductor 1 is installed in above the single-column construction elevator cage, the described reductor 1 casing 2 outer dual output gears 5 that are provided with, described dual output gear 5 is meshed with the guide rail bracket upper rack, the number of teeth of described dual output gear 5 is 12, modulus is 8, described guide rail bracket tooth bar is double rack, the dual output gear 5 of described reductor 1 is meshed with the guide rail bracket double rack, power output is exported by two output gears like this, make braking force disperse transmission, having reduced stress concentrates, improved the load-carrying capacity of power, velocity limiter can make specified brake load improve by this reductor 1, is applicable to large capacity, the single-column building hoist of large load.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
