Abstract
The invention discloses a car platform weighing structure and an elevator comprising the car platform weighing structure. The car platform weighing structure comprises first connecting blocks, second connecting blocks, first connecting rods, a second connecting rod and an induction piece, wherein the first connecting blocks are rotatably connected with the first connecting rods; the second connecting blocks are rotatably connected with the second connecting rod and are fixed on the first connecting rods; the induction piece is mounted on the second connecting rod. When the car platform of an elevator car deforms under the action of a load, the first connecting blocks deflect accordingly; as the first connecting blocks are rotatably connected with the first connecting rods and the second connecting rod is rotatably connected with the second connecting blocks, the transmission of deflection from the first connecting blocks and the second connecting blocks to the first connecting rods and the second connecting rod is cut off, so that the first connecting rods and the second connecting rod do not bend and deform and the amount of movement of the induction piece caused by deflection and bending deformation is further reduced; in such a way, influence on authenticity of test data from the bottom deformation of the elevator car is reduced to the minimum extent, the authenticity of the data is increased and further the ride comfort of the elevator car is improved.
Description
Technical field
The present invention relates to elevator field, the elevator of weighing structure at the bottom of particularly relating to weighing structure at the bottom of sedan-chair and comprising this sedan-chair.
Background technology
Elevator is when starting, can declutch suddenly, the traction sheave converse rotating force of main frame increases suddenly, if can not carry out good control to this process, will cause elevator to start unstable, make lift car produce vibrations, reduced the traveling comfort of taking, for this reason, apparatus for controlling elevator need to calculate the size of required traction, and finally realizes lift car smooth starting.
Apparatus for controlling elevator is before calculating the size of required traction, need to carry out data acquisition, the accuracy of data acquisition has directly determined whether traction calculating is accurate, final decision the travelling comfort of lift car, generally by detections, be fixed on the load-carrying that the sensing chip bottom lift car calculates lift car from the distance that is arranged on sedan-chair underframe upper sensor, thereby calculate the size of required traction, during due to elevator car loading, can there is certain distortion, thereby can cause the data distortion detecting, finally make the traction size distortion calculating, reduced the traveling comfort of elevator ride.
Summary of the invention
The object of the present invention is to provide weighing structure at the bottom of a kind of sedan-chair of weighing more accurately.
Another object of the present invention is to provide a kind of more comfortable elevator of taking.
In order to realize object of the present invention, the technical scheme of taking is:
Weighing structure at the bottom of a kind of sedan-chair, comprise the first contiguous block, the second contiguous block, head rod, the second pipe link and induction pieces, the first contiguous block and head rod are rotatably connected, the second contiguous block and the second pipe link are rotatably connected, the second contiguous block is fixed on head rod, and induction pieces is installed on the second pipe link.At the bottom of sedan-chair, weighing structure is installed on lift car at the bottom of sedan-chair or weighs on rubber, lift car lowermost end is sedan-chair underframe, on sedan-chair underframe, sensor is installed, by the spacing between detecting sensor and induction pieces, change and just can obtain the load-carrying of lift car, the first contiguous block is fixed on lift car at the bottom of sedan-chair or weighs on rubber, while deforming at the bottom of sedan-chair on lift car is being subject under the effect of load, the first contiguous block also can be ensued deflection, owing to being rotatably connected between the first contiguous block and head rod, after the first contiguous block deflection, head rod can deflect and can not bend by relative the first contiguous block, the second contiguous block is fixed on head rod, between the second contiguous block and the second pipe link, be rotatably connected, when head rod is when certain deflection occurs for self usable rotational direction, the second contiguous block can and then produce onesize deflection, owing to being rotatably connected between the second pipe link and the second contiguous block, the second pipe link can deflect and can not bend by relative the second contiguous block, like this, distortion at the bottom of upper sedan-chair is seldom delivered on weighing structure induction pieces, weighing structure can be reacted the amount of compression of the rubber of weighing more realistically.In this way, lift car deformation of bottom is reduced to minimum level to detecting the authenticity impact of data, has improved the authenticity of data, and then improved the traveling comfort that lift car is taken.Especially, when elevator lift car load skewness, the data that existing elevator measures are larger with real data deviation, in real process, can cause lift car vibrations larger, travelling comfort is very poor, while adopting structure of the present invention, when elevator lift car load skewness, wherein certain first contiguous block deflection angle is slightly large, the deflection angle of other several the first contiguous blocks is less, the component that several the first contiguous blocks that deflection angle is less are delivered on head rod is less, and then the component being delivered on the second pipe link is less, when that first contiguous block that deflection angle is slightly large is delivered to head rod, the amount of deflection of head rod can reduce, be the equal of that deflection angle has been carried out correcting for the first time, the amount of deflection that head rod is delivered on the second pipe link can further reduce, be equivalent to deflection angle to carry out correcting for the second time, thereby make data measured truer, effectively, by weighing structure at the bottom of this articulated sedan-chair, lift car deformation effect can be reduced to very little scope, improved greatly the traveling comfort of elevator ride.
