Embodiment Construction

[0027] As shown in Figure 1, the elevator traction wire rope 2 is connected to the car 11 and the counterweight 3 through the traction sheave 10 and the driven wheel 1, and the compensation chain 9 under the car 11 is connected to the bottom of the counterweight 3 through the pulleys 7, 8 to transmit force. The device 4 is installed on the buffer or bracket 6, and the output of the force transmitter 4 is connected to the test instrument 5.

[0028] When measuring, first adjust the car 11 and the counterweight 3 to an appropriate position, so that the connecting points A and B of the traction rope 2 with the car 11 and the counterweight 3 are in the same horizontal position (the position shown by the dotted line in the figure) ) To record the location. At the same time to obtain μ, N, ρ 1 , Ρ 2 value.

[0029] When the elevator is empty, run the elevator car 11 to the top of the elevator hoistway, make the counterweight 3 descend to the bottom of the hoistway, and keep the distance...

Abstract

The invention discloses a static two sides weight differential measurement method of lift coefficient of balance according to the lift balance coefficient formula (I)through measuring the weight differential Wg=(W-G) of the pair weight and the sedan wing and gives the lift rated load capacity Q then calculates the balance coefficient K. The method is that: at the condition of lift with no-load layouts the force transducer at the bottom of well corresponding with the pair weight and the pair weight falls down to the bottom of well and contacts with the force transducer then measures the weight differential Wg1 of the pair weight side and the sedan wing side; installs the poise with the carrying capacity QP in the sedan wing (QP is greater than the one-half of the lift rated carrying capacity) layouts the force transducer at the bottom of well corresponding with the sedan wing the sedan wing falls down to the bottom of well and contacts with the force transducer then measures the weight differential Wg2 of the sedan wing side and the pair weight side and calculates the balance coefficient K according to the formula(II)following the weight differentia Wg1, Wg2, the lift rated carrying capacity Q, and the bearing capacity QP. According to this method develop the lift balance coefficient test device which can measure the lift balance coefficient directly, accurately, and rapidly at the static case.

Description

Technical field [0001] The invention relates to a method for measuring the balance coefficient of an elevator, in particular to a method for measuring the balance coefficient of an elevator by the static two-side weight difference of the elevator balance coefficient. Background technique [0002] Elevator balance coefficient is an important parameter that needs to be measured on site during elevator installation, acceptance and use. At present, the measurement method commonly used at home and abroad is to measure the voltage, current and other parameters of the traction motor during the operation of the elevator, and obtain the elevator balance coefficient through calculation and drawing. In the measurement, the elevator supervision and inspection regulations must be followed for many times. The elevator applies different loads. This measurement method is an indirect measurement method, which is time-consuming and labor-intensive, and has large errors. It is difficult to obtain a...
