Description
Technical field
The utility model belongs to technical field of elevator manufacturing, is specifically related to a kind of hitch of large-tonnage lift car.
Background technology
For cargo lift, when loading and unloading Cargo Lift, due to distant to guide rail of edge, car doorway, during goods turnover car, larger moment can be produced, to car, guide rail with lead the bending force that boot-shaped becomes very large, the cargo lift that particularly car depth is larger and car elevator, during handling goods, car, guide rail and the impulsive force of leading suffered by boots larger, for ensureing the use safety of elevator, thus higher to the requirement of strength of these parts, and moment is easier to car, guide rail with lead these some parts of boots and cause damage.
Usually, the car body of elevator is suspended on the rope sheave of car roof, and when the traction ratio of elevator is 2:1, rope sheave is arranged in the midway location before and after car, and rope sheave plane parallel is in front and back two plane of car.
But for large-tonnage cargo lift, because the area of car is comparatively large, the degree of depth of car often all reaches more than 4m, and particularly for car elevator, the degree of depth of car is even more than 7m.In this case, if the arrangement of car sheave is still arranged in the midway location of car, due to distant to car body rope sheave of stressed place, edge before and after car, when weight turnover car, very large moment will be produced, easily cause the inclination of car, at the same time, the application force that car produces guide rail is very large, for ensureing that car does not tilt, just must the intensity of differentiate boots and guide rail high especially, even if the intensity leading boots and guide rail reaches certain standard, but elevator is through long term, car, lead boots, guide rail is also easily damaged.
Summary of the invention
The utility model in prior art because car depth is darker, the midway location that car sheave is arranged in car easily causes the inclination of car, and easily to leading boots, the parts such as guide rail cause the drawback of damage, provide a kind of hitch of large-tonnage lift car, this hitch arranges a main car frame in the middle of car and the position that keeps to the side at car two ends arranges two secondary car frames, two secondary car frames are installed sedan-chair top rope sheave, car is made to be in a state of equilibrium, and the secondary car frame of both sides can play to car the effect keeping balance when weight turnover car.
Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of hitch of large-tonnage lift car, comprise car frame, be arranged on the car on car frame, described car frame is made up of a main car frame and two secondary car frames, main car frame is arranged on the midway location of car, main car frame both sides are arranged on the guide rail of elevator, be provided with outside main car frame coordinate with guide rail in elevator lead boots, two secondary car frames are separately positioned on car two ends and keep to the side position, each secondary car frame top is provided with two sedan-chair top rope sheaves, two sedan-chair top rope sheaves be separately positioned on secondary both sides, car frame top and and secondary car frame in the same plane, sedan-chair top rope sheave on two secondary car frames is parallel to each other, have in the sedan-chair top rope sheave that two secondary car frames are arranged above three sedan-chair top rope sheaves and be provided with counterweight sheave, parallel to each other and the plane at each counterweight sheave place of the plane at each counterweight sheave place and rope sheave place, sedan-chair top plane orthogonal, be provided with traction steel-cable between each sedan-chair top rope sheave and counterweight sheave, traction steel-cable two ends are connected on the traction system of elevator.
As preferably, two sedan-chair top rope sheaves on each secondary car frame are equal to the distance at edge, the secondary car frame left and right sides.Keep car balance, and ensure two rope sheave sedan-chair top uniform force on secondary car frame.
Compared with prior art, the utility model has following beneficial effect: the utility model arranges a main car frame in the middle of car and the position that keeps to the side at car two ends arranges two secondary car frames, two secondary car frames are installed sedan-chair top rope sheave, namely the traction system of elevator acts on two secondary car frames, and main car frame be arranged on elevator guide rail on play the effect of guiding, arranging like this can make car be in a state more balanced, and when weight turnover car, the secondary car frame of both sides can play to car the effect keeping balance, car is to leading boots, the application force that guide rail produces reduces, can effectively reduce and lead boots, the degree that guide rail is impaired, and can car be extended, lead boots, the service life of guide rail.

Mark in figure: 1, car frame, 2, car, 3, main car frame, 4, secondary car frame, 5, guide rail, 6, lead boots, 7, sedan-chair top rope sheave, 8, counterweight sheave, 9, traction steel-cable.
Detailed description of the invention
Below in conjunction with the embodiment represented by accompanying drawing 1, the utility model is further described:
Embodiment 1
A kind of hitch of large-tonnage lift car, comprise car frame 1, be arranged on the car 2 on car frame 1, described car frame 1 is made up of a main car frame 3 and two secondary car frames 4, main car frame 3 is arranged on the midway location of car 2, main car frame 3 both sides are arranged on the guide rail 5 of elevator, be provided with outside main car frame 3 coordinate with guide rail in elevator 5 lead boots 6, two secondary car frames 4 are separately positioned on car 2 two ends and keep to the side position, each secondary car frame 4 top is provided with two sedan-chair top rope sheaves 7, two sedan-chair top rope sheaves 7 be separately positioned on secondary both sides, car frame 4 top and and secondary car frame 4 in the same plane, sedan-chair top rope sheave 7 on two secondary car frames 4 is parallel to each other, two sedan-chair top rope sheaves 7 on each secondary car frame 4 are equal to the distance at edge, secondary car frame 4 left and right sides.Have above three sedan-chair top rope sheaves 7 and be provided with counterweight sheave 8 in the sedan-chair top rope sheave 7 that two secondary car frames 4 are arranged, the parallel to each other and plane at each counterweight sheave 8 place of the plane at each counterweight sheave 8 place and rope sheave 7 place, sedan-chair top plane orthogonal; Be provided with traction steel-cable 9 between each sedan-chair top rope sheave 7 and counterweight sheave 8, traction steel-cable 9 two ends are connected on the traction system of elevator.
The traction ratio of this elevator is 4:1, nearer owing to hanging stress point distance car entrance place, when weight turnover car body, the moment produced will significantly reduce, effectively can solve existing large-tonnage car body because stressed place, edge, front and back is to car sheave distant to guide rail with lead boots and easily produce very high-torque and the problem causing damage, and this structural bearing is stablized, simultaneously, due to the significantly reduction of moment during carrying, car can reduce a lot to guide rail and the application force of leading boots, can effectively reduce and lead boots, the degree that guide rail is impaired, and can car be extended, lead boots, the service life of guide rail.
Specific embodiment described in literary composition is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
