Background technology
In
prior art; Car load weigh sensor probe and the square magnet steel of usefulness be contained at the bottom of the sedan-chair below, also must be adjusted at the center of car, when debugging; Need be parked in the bottom appropriate location to car; The personnel of debugging get into behind the pit sensor at the bottom of the sedan-chair are debugged then, the distance between adjustment probe and the square magnet steel for example, operation inconvenience very like this.Existing sensors probe and square magnet steel are contained in the beneath side of sedan-chair; Deformation through the shock-absorbing rubber of face under the measurement sedan-chair detects car load; If car load overbalance like this; Like the center of the position deviation car at passenger station in the car, cause being difficult to confirm accurately the deformation quantity of rubber, cause the inaccurate of car load measurement.
Summary of the invention
The purpose of
the utility model provides to install and makes things convenient for debugging operations and measure lift car load weighting apparatus accurately.
are for achieving the above object; The technical scheme that the utility model adopts is: lift car load weighting apparatus; Comprise rope hitch plate, be arranged on the fag end assembly on the said rope hitch plate; Offer on the said rope hitch plate perforation be installed, said fag end assembly comprise the screw rod that can be through slidably in the said installation perforation, through screw thread fit at a pair of nut on the said screw rod, be arranged on the elastic component that is used to provide this screw rod elastic-restoring force between said screw rod and the said rope hitch plate, the direction of slip of said screw rod and its axial direction are consistent; Said weighting apparatus also comprises adapter plate, be contained in sensor probe on the said adapter plate, be contained in the sensor side's magnet steel on the said rope hitch plate; Said sensor probe is magnet steel over against said sensor side, and between said sensor probe and the said sensor side magnet steel distance of reaction is arranged, and offers mounting hole on the said adapter plate; Said screw rod is through in the said mounting hole, and said adapter plate is clamped between the said a pair of nut.
Preferably, said screw rod vertically is provided with
, and the bottom of said screw rod can be through in the installation perforation of said rope hitch plate along it axially slidably; Said adapter plate is clamped in the upper end of said screw rod by said a pair of nut; Said elastic component adopts spring, and this spring housing is located on the said screw rod, and this spring is pressed between said nut and the said rope hitch plate; The part of horizontal setting at least of the upper face of said rope hitch plate; Horizontally disposed upper face is provided with said sensor side magnet steel, and said sensor probe vertically is provided with, and be positioned at said sensor side magnet steel directly over.
preferably; Said adapter plate is connected with said sensor probe through support; Offer tapped bore on the said adapter plate, offer perforation on the said support, said perforation is passed by the screw thread body portion of screw; Screw in the said tapped bore, the head of this screw compresses said support on said adapter plate through packing ring.
because the utilization of technique scheme, the utility model compared with prior art has advantage: those skilled in the art knows, screw rod passes on the end of rope hitch plate and is connected with traction steel-cable through coupling assembling; Traction steel-cable is stressed; Then the screw rod elastic resistance that can overcome elastic component slides, and is when lift car carries the passenger, unloaded with respect to car; Traction steel-cable is further stressed; Be that screw rod is further stressed, the elastic resistance that overcomes elastic component slides with respect to rope hitch plate, based on the deformational displacement of elastic component; Distance of reaction between sensor probe and the sensor side's magnet steel changes, thereby can measure car load.This measurement is based on the displacement of the stressed generation of car load, and whether balance is irrelevant with car load, so measure accurately.Car load is measured and is installed on fag end assembly and the rope hitch plate with sensor probe and square magnet steel, so when installing and debug, for the elevator that machine room is arranged; Directly get final product to machine room; For the elevator of no machine room, installation personnel can good sensor probe of direct mount and square magnet steel when car or counterweight fag end frame are installed, and stops car in position in the time of debugging; On the sedan-chair top, just can operate, more convenient.
Description of drawings
accompanying drawing 1 is the scheme drawing of the utility model.
The specific embodiment
The structure of the utility model is further set forth in
below in conjunction with accompanying drawing.
referring to shown in Figure 1, and lift car load weighting apparatus comprises rope hitch plate 1, is arranged on fag end assembly 9, adapter plate 5 on the rope hitch plate 1, is contained in sensor probe 7 on the adapter plate 5, is contained in the sensor side's magnet steel 8 on the rope hitch plate 1; Offer on the rope hitch plate 1 perforation be installed, fag end assembly 9 comprise can be through slidably the screw rod 2 installed in the perforation, through screw thread fit at a pair of nut 3 on the screw rod 2, be arranged on the elastic component 4 that is used to provide these screw rod 2 elastic-restoring forces between screw rod 2 and the rope hitch plate 1, the screw rod 2 among Fig. 1 vertically is provided with; The bottom of screw rod 2 can be through in the installation perforation of rope hitch plate 1 along it axially slidably, offers mounting hole on the adapter plate 5, and the upper end of screw rod 2 is through in the mounting hole; Adapter plate 5 is clamped between a pair of nut 3, and promptly in the upper end of screw rod 2, elastic component 4 adopts spring to adapter plate 5 by a pair of nut 3 clamp fittings; This spring housing is located on the screw rod 2, and this spring is pressed between nut 3 and the rope hitch plate 1, and screw rod 2 passes on the bottom of rope hitch plate 1 through the coupling assembling (not shown) that is connected with traction steel-cable; Traction steel-cable is stressed, and then screw rod 2 can slide the part of horizontal setting at least of the upper face of rope hitch plate 1 by compression elastic piece 4; Horizontally disposed upper face is provided with sensor side's magnet steel 8; Sensor probe 7 vertically is provided with, and be positioned at sensor side's magnet steel 8 directly over, between sensor probe 7 and the sensor side's magnet steel 8 distance of reaction is arranged; When lift car is unloaded; This distance of reaction is 15 ~ 20mm, and is when lift car carries the passenger, unloaded with respect to car; Traction steel-cable is further stressed; Be that screw rod 2 is further stressed, the elastic resistance that overcomes elastic component 4 with respect to rope hitch plate 1 to lower slider, based on the deformational displacement of elastic component 4; Distance of reaction between sensor probe 7 and the sensor side's magnet steel 8 changes, thereby can measure car load.This measurement is based on the displacement of the stressed generation of car load, and whether balance is irrelevant with car load, so measure accurately.Car load is measured and is installed on fag end assembly and the rope hitch plate with sensor probe and square magnet steel, so when installing and debug, for the elevator that machine room is arranged; Directly get final product to machine room; For the elevator of no machine room, installation personnel can good sensor probe of direct mount and square magnet steel when car or counterweight fag end frame are installed, and stops car in position in the time of debugging; On the sedan-chair top, just can operate, more convenient.
