Application examples 1
Below, the testing process of the balance coefficient of elevator detecting device 100 of the first preferred embodiment is described.
During balance coefficient of elevator test, lift car M1 and counterweight M2 are successively moved to the top position of hoistway, this balance coefficient of elevator detecting device 100 is installed.
For example, first lift car zero load is moved to the top position of hoistway, above car, chooses cage side as the length of cable that detects target, with can safety, this balance coefficient of elevator detecting device 100 is installed convenient operation and is as the criterion.Four groups of rope slings 13 of two the first fixture blocks 11 are alignd with corresponding four steel ropes 1 respectively, fastening assembly 14 is installed, by the fastener 142 that tights a bolt, two the first fixture blocks is applied to gripping power, with clamping steel wire rope 1 respectively, realize the relative fixing of two the first fixture blocks 11 and steel rope 1.Subsequently, rope tractor 40 is installed, the base of cable traction device 40 401 is clamped on one of them first fixture block 11.Then the position of the suitable distance of distance the first fixture block below the first fixture block, four groups of rope slings 13 of two the second fixture blocks 12 are alignd with corresponding four steel ropes 1 respectively, fastening assembly 14 is installed, by the fastener 142 that tights a bolt, two the second fixture blocks are applied to gripping power, with clamping steel wire rope 1, realize the relative fixing of two the second fixture blocks 12 and steel rope 1.Rope assembly 20 is then installed.Rope anchor 201 is fixedly mounted on another first fixture block that does not clamp cable traction device 40, between rope anchor 201 and cable traction device 40 across steel rope 1.By rope guide 202 across being arranged on two the second fixture blocks 12.Rope anchor 201 is fixed on in one end of rope 203, and the other end, through the pulley on rope guide 202, is fastenedly connected with the tractive unit 402 of cable traction device 40.So far, as shown in Figure 4, complete the installation of this balance coefficient of elevator detecting device 100.Now, the steel rope being clipped between the first fixture block and the second fixture block is the above-mentioned length of cable as detecting target.
Subsequently, operation rope tractor 40, slowly promotes tractive unit 402, and tractive unit 402 draws and strain rope 203, until the steel rope 1 between the first fixture block and the second fixture block is in the state of not stressing.After this, continue to promote tractive unit 402, car 70 with on move, in the process of slowly moving at the uniform velocity at car 70, record the value F1 on force indicator 50, utilize conventional means just can obtain the dynamic cage side weight of elevator G1 by F1.Finish subsequently to promote, make car static, record the value F2 on force indicator 50 now, by conventional means, just can obtain the cage side weight G2 of elevator when static by F2 equally.
In like manner, while measuring the weight of counterweight 80 sides, also be first counterweight 80 to be moved to the top position of hoistway, above counterweight 80, choose heavy side as the length of cable that detects target, with can safety, this balance coefficient of elevator detecting device 100 is installed convenient operation and is as the criterion.Repeat after the installation process of above-mentioned balance coefficient of elevator detecting device 100, operation rope tractor 40, slowly promotes tractive unit 402, until the steel rope 1 between the first fixture block and the second fixture block is in the state of not stressing.After this, continue to promote tractive unit 402, counterweight 80 with on move, in the process of slowly moving at the uniform velocity at counterweight 80, record the value F3 on force indicator 50, utilize conventional means just can obtain the dynamic counterweight of the elevator amount of stressing W1 by F3.Finish subsequently to promote, make counterweight static, record the value F4 on force indicator 50 now, same, utilize conventional means just can obtain counterweight the stress amount W2 of elevator when static by F4.
Subsequently, the counterweight amount of stressing W1, W2 when cage side weight G1, G2 when elevator is dynamic, static and elevator are dynamic, static, be updated to equilibrium factor algorithmic formula K=(W-G) in/Q, K is equilibrium factor, W is the counterweight amount of stressing, and W is the counterweight amount of stressing, and G is cage side weight.Thereby, obtain the dynamical equilibrium COEFFICIENT K 1=(W1-G1 of elevator) and static balancing COEFFICIENT K 2=(the W2-G2)/Q of/Q and elevator.
