Embodiment
Embodiment 1: with reference to accompanying drawing 1～3.A kind of elevator balanced load testing appearance; It comprises support 4, pressure transducer 5, pressure transducer base plate 6 and instrument 7, and said pressure transducer 5 is arranged between support 4 and the pressure transducer base plate 6, and pressure transducer base plate 6 two ends are connected with a chain 2 respectively; The other end of chain 2 is fixed in the outside surface of steel wire clamping plate 1; The signal output part of pressure transducer 5 links to each other with the signal input part of instrument 7, and the signal output part of instrument 7 connects the signal input part of host computer 8, and augmentor 3 is installed on the top, two ends of support 4; Symmetrical boss clamping plate 9 before and after steel wire clamping plate 1 comprises; The boss of two boss clamping plate 9 opposed inside faces is provided with vertical groove parallel to each other 10, and groove 10 matches with the traction steel-cable 12 of elevator main 11, and two boss clamping plate 9 pass through bolt combination; Said pressure transducer 5 is " protruding " font, and the upper and lower surface of pressure transducer 5 is close to the bottom surface and the upper surface of support 4 and pressure transducer base plate 6 respectively through bolt mutually.
The principle of work of balance coefficient of elevator test: balance coefficient of elevator is exactly counterweight and car ratio number percent; Computing formula is W=P+KQ; Wherein: W is the counterweight quality, and P is the car deadweight, and Q is the car payload ratings; K is coefficient of balance (K: Cargo Lift is generally got 0.45-0.55, and elevator is generally got between the 0.4-0.5); The utility model lets and to focusing under the action of gravity car is moved through opening detent; The chain of instrument slowly tightens up; Slowly be loaded into weight on the pressure transducer, car stops to move when equipment is stressed when equating with the counterweight quality with car deadweight addition, at this moment two lateral balances; The weight that is carried on the pressure transducer is exactly the difference of counterweight and car deadweight, can calculate the coefficient of balance K of elevator through computing formula W=P+KQ.
The principle of work of 150% static test: the static test operation is the same with the early-stage preparations operation of doing the balance coefficient of elevator test; Install equipment components and remove the peel; Through the augmentor application of force between main control system spandrel girder and the instrument support, regulate the height of augmentor again, power is applied on the traction steel-cable of elevator traction machine through the tension chain; Be equal to and in car, add counterweight; When host computer reflect the power that applies reach payload ratings 150% the time stop the augmentor application of force, and after lasting 10min minute, detect traction steel-cable and whether traction sheave exists skidding, thereby whether the analysis and judgement elevator reaches criterion of acceptability.
The principle of work of traction sheave friction testing: the operation of traction sheave friction testing is the same with the early-stage preparations operation of doing the balance coefficient of elevator test; Install equipment components and remove the peel; Augmentor through between operating host spandrel girder and the instrument support is exerted pressure, and regulates the height of augmentor, power is applied to the traction steel-cable of elevator traction machine through the tension chain; And the power of bearing on the traction steel-cable is constantly increased; Until letting grooving and traction steel-cable skid, data presented is just represented the friction force between traction sheave and the wire rope on the host computer at this moment, simultaneously; The staff can extrapolate the cornerite on the elevator rope sheave through this test, and whether traction is fit to design must be asked.
What need understand is: though the foregoing description is to this practical mentality of designing detailed text description of contrasting; But these text descriptions; Just the simple text of this practical design thinking is described; Rather than to the restriction of this practical design thinking, any combination, increase or modification that does not exceed this practical design thinking all falls in this practical protection domain.
