Specific embodiment

With reference to Figure of description, the utility model is described in further detail.

This elevator brake performance detecting system is by primary module, traction sheave side senser module and steel wire rope side senser module Three parts form, and for examining testing agency, all modules of the present apparatus are using independently-powered (lithium battery), for producer, sheet All modules of device are powered by emergency power supply.Present apparatus composition schematic diagram is as shown in Fig. 2, specifically arrange schematic diagram such as Fig. 3 Shown, therein 1 is elevator traction sheave, and 2 be steel wire rope, and 3 fix girder steel for elevator host, and 4 be steel wire rope side senser module, 5 be traction sheave side senser module, and 6 be elevator main power source control cabinet, and 7 be the primary module of the system, and 9 be balance weight, and 10 be to multiply Objective car, 11 be safety tongs linkage, and 12 be speed limiter wire rope, and 13 be speed limiter wire rope swelling device, and 14 be speed limit Device wheel axle center encoder, 15 be limiter of speed side senser module, and 16 be traction sheave axle center encoder.The structure diagram of primary module As shown in figure 4, wherein 1 is display screen, 2 be main module body, and 3 be button, and 4 be plug, and 5 be detection folder, and 6 be detection conducting wire. The traction sheave side senser module of steel wire rope side senser module and wheel outer rim form is same type sensor, and module is positive With side schematic view difference as shown in Figure 5 and Figure 6, wherein the 1 of Fig. 5 is passive detection wheel, and 2 be fixed link, and 3 be rotatable shaft, 4 be force application spring, and 5 be telescopic rod adjusting knob, and 6 be cable, and 7 be module body, and the 8 of Fig. 6 is rotary encoder.

The work flow diagram of this elevator brake performance detecting system is as shown in Figure 1.Primary module is fixed on elevator first Beside power main switch, and pass through detection folder (5 in Fig. 4) and be fixed on power end or be directly inserted by plug (4 in Fig. 4) In socket, it is detected hence for the energization situation of elevator.

Two sensor assemblies have different positions according to different test formats, wherein, axle center detection uses Rotation distance and speed are directly detected in the position that rotary encoder (14 in Fig. 3 and 16) is fixed on wheel axle center, and other modes Then by adjusting knob (5 in Fig. 5) realize passive detection wheel the 1 of Fig. 6 (Fig. 5 and) and steel wire rope/wheel (in Fig. 32 or In 12/ Fig. 31 or 8) relative position is suitable, keep suitably contacting so as to pass through both force application springs (4 in Fig. 5) Power finally detects corresponding range ability.

Before starting to do uplink/downlink retardation test, three module elder generation opening initializations establish wireless connection, composition Network then inputs the traction ratio parameter K of elevator, so as to complete the initialization of system by the button (3 in Fig. 4) of primary module And configuration.Elevator brings into operation, and the sensor assembly of steel wire rope side and traction sheave side measures range ability in real time respectively, calculates steel The speed V1 of circle where cord and traction sheave test point place round wires speed V2 is simultaneously sent to primary module, and primary module is then to two speed Degrees of data is matched, and proportionality coefficient P=V1/V2 is calculated on the basis of steel wire rope side.When elevator is run to suitable position When, elevator power supply main switch disconnects, and primary module detects power-off, power-off signal is sent to two modules, steel wire rope therein Side form block is received zeros data after signal, restarts to measure range ability S1, and after traction sheave side form block receives signal By zeros data, restart to measure range ability S2, and start timing, until traction sheave stops completely, obtain time T1. After steel wire rope and traction sheave all stop completely, two sensor assemblies transmit data to primary module, and primary module passes through ratio system Number P, traction ratio parameter K and two range data, conversion obtain steel wire iope slippage distance S=S1-P*S2, car braking distance S_c=S1/K, brake body stop delay time are then T1, brake delay braking distance S_b=P*S2, finally, primary module will Above-mentioned data are shown by display screen.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modifications, equivalent replacements and improvements are made should be included within the scope of protection of this utility model.
