Described fag end spring is placed on the circular hole of described intermediate support plate upper surface by spring perch.
Described eddy current sensor hinders between magnetic sheet for induction coordinates with eddy current sensor, by changing the distance of reaction between the two, and then the output voltage of change eddy current sensor, elevator device carries out system computing according to this output voltage, can obtain the weight information of lift car.
When lift % load, described overload detector switch touch panel moves down and just in time triggers overload detector switch with intermediate support plate, makes elevator out of service and report to the police.
When lift car side-lining rope slack rope or disconnected rope, described slack rope detector switch touch panel triggers slack rope detector switch with moving on intermediate support plate, makes elevator out of service.
The invention has the beneficial effects as follows:
First, the present invention realizes elevator weighing at lift car side-lining rope fag end dexterously, has cancelled at the bottom of traditional sedan-chair double-decker at the bottom of eddy current sensor and sedan-chair, has reduced car material cost and design difficulty, also reduce elevator weighing apparatus installment and debugging difficulty, saved engineering and cost of labor.
Secondly, combination by two kinds of elastic partss and intermediate support plate configures, can realize the even tension adjustment of every hauling rope, guarantee midship mounting plate level, improve weighing-up wave accuracy of detection, on the other hand, hauling rope even tension, also improve the condition of service of hauling rope, improved hauling rope service life.
Moreover the setting of overload detector switch and slack rope detector switch, also guarantees that elevator does not move when overload and slack rope, meets national elevator standard requirement, improves the safety in utilization of elevator.
Accompanying drawing explanation
Fig. 1 is the structural representation of elevator weighing apparatus of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described.
As shown in Figure 1, a kind of elevator weighing apparatus, comprise the rope hitch plate 1 being fixedly installed and the intermediate support plate 4 that is positioned at rope hitch plate 1 top, between rope hitch plate 1 and intermediate support plate 4, be provided with several rubber tubes 12 that distribute side by side, the upper end of intermediate support plate 4 is provided with several fag end springs 9 corresponding with rubber tube 12, and fag end spring 9 is specifically placed on the circular hole of intermediate support plate 4 upper surfaces by spring perch 10.On rope hitch plate 1, be provided with eddy current sensor 13, overload detector switch 2, slack rope detector switch support 5 and slack rope detector switch 6, the slack rope detector switch touch panel 7 that the eddy current sensor resistance magnetic sheet 11 coordinating with eddy current sensor 13 inductions, the overload detector switch touch panel 3 matching with overload detector switch 2 is installed on intermediate support plate 4 and matches with slack rope detector switch 6.Also comprise several fag end pull bars 14 corresponding with rubber tube 12 and fag end spring 9, fag end pull bar 14 passes the through hole of rope hitch plate 1, rubber tube 12, intermediate support plate 4, spring perch 10 and fag end spring 9 successively, fag end pull bar 14 one end are provided with in order to the fixing tightening nut 8 of fag end spring 9, and fag end pull bar 14 other ends are connected with lift car side-lining rope by coupling assembling.
When the lift car side-lining rope tension masterpiece used time, power is delivered on fag end pull bar 14, by the tightening nut 8 being arranged on fag end pull bar 14, exert pressure on fag end spring 9, pressure is delivered to the rope hitch plate 1 being fixedly installed from fag end spring 9, spring perch 10, intermediate support plate 4, rubber tube 12 successively.The effect of pressure can make fag end spring 9 and rubber tube 12 compressive deformations, distance between corresponding intermediate support plate 4 and rope hitch plate 1 can be dwindled, thereby change the distance of reaction between eddy current sensor 13 and eddy current sensor resistance magnetic sheet 11, and then the output voltage of change eddy current sensor 13, elevator device carries out system computing according to this output voltage, can obtain the weight information of lift car.
Elevator for a certain payload ratings, rubber tube 12 and the fag end spring 9 of the applicable specification of configuration, when lift car is unloaded, rubber tube 12 amount of compressions are N, eddy current sensor 13 is 10mm with the distance of reaction of eddy current sensor resistance magnetic sheet 11, when lift car at full load, rubber tube 12 amount of compressions are N+6mm, eddy current sensor 13 is 4mm with the distance of reaction of eddy current sensor resistance magnetic sheet 11, when lift % load, rubber tube 12 amount of compressions are N+7mm, eddy current sensor 13 is 3mm with the distance of reaction of eddy current sensor resistance magnetic sheet 11, now overload detector switch touch panel 3 moves down and just in time triggers overload detector switch 2 with intermediate support plate 4, make elevator out of service and report to the police.
Eddy current sensor 13 hinders magnetic sheet 11, overload detector switch 2 and overload detector switch touch panel 3 and slack rope detector switch 6 and slack rope detector switch touch panel 7 respectively in same vertical line position with eddy current sensor, and eddy current sensor resistance magnetic sheet 11, overload detector switch touch panel 3 and slack rope detector switch touch panel 7 are screwed onto respectively on the default screw of intermediate support plate 4.So, the adjustment of weighting apparatus can be by regulating the vertical distance of eddy current sensor resistance magnetic sheet 11, overload detector switch touch panel 3 and slack rope detector switch touch panel 7 to proofread and correct, convenient and reliable operation.
When lift car side-lining rope slack rope or disconnected rope, fag end pull bar 14 is stressed significantly to be reduced, now rubber tube 12 amount of compressions significantly reduce, thereby jack-up intermediate support plate 4, make the slack rope detector switch touch panel 7 being fixed thereon trigger 6 actions of slack rope detector switch, and make elevator out of service, guarantee elevator safety.
When lift car side-lining rope occurs that tension force is uneven, can change by tightening nut 8 amount of compression of fag end spring 9, make the length variation of different fag end springs 9 in 1～2mm, simultaneously, with spirit level, measure the horizontality of intermediate support plate 4, when intermediate support plate level, and different fag end spring length variation is when meet the requirements, can make different hauling rope even tensions, weighing-up wave detects accurately.
As described above, it is only preferred embodiment of the present invention, when not limiting scope of the invention process with this, the simple equivalence of generally doing according to the present patent application the scope of the claims and invention description content changes and modifies, and all still remains within the scope of the patent.
