Description
Technical Field
The invention belongs to the technical field of elevator auxiliary operation equipment, relates to a measuring device, and particularly relates to an elevator balance coefficient measuring device.
Background
The elevator balance coefficient is an important performance index of a traction type driving elevator and needs field measurement. The reasonable setting of the elevator balance coefficient can not only ensure the brake of the elevator brake in the brake range, but also save a large amount of electric energy resources. The cage and the counterweight of the traction elevator are respectively suspended on two sides of a traction sheave through steel wire ropes, and section G2.4 in GB7588-2003 gives a definition of a balance coefficient (q), namely the rated load capacity and the amount of the mass of the cage balanced by the counterweight or the counterweight. Thus, it calculates the formula:
q=（W-P）/Q
wherein: q is the equilibrium coefficient; w-the weight of the counterweight, kg; p-car mass, kg; q is rated load capacity; and (kg).
At present, the measurement method commonly adopted at home and abroad is to load test blocks with rated load capacity of 30%, 40%, 45%, 50% and 60% respectively in a car to carry out up-and-down full-stroke operation, when the car and a counterweight move to the same horizontal position, the current value of a car hoisting motor is recorded, a current-load curve is drawn, and the balance coefficient is determined by the intersection point of the up-and-down operation curves. The measurement method is an indirect measurement method, the elevator car needs to be manually carried and loaded according to different loading amounts in the measurement process, time and labor are wasted, the efficiency is low, large errors exist, and accurate elevator balance coefficients are difficult to obtain.
At present, the influence of elevator balance coefficients on elevator brakes is very large in the domestic elevator industry, so that the national quality inspection bureau issues announcements of 6 safety technical specification No. 2 modification lists of elevator supervision and inspection and regular inspection rules, traction and forced driving elevators and the like in 2017, 6 and 12 days, the balance coefficient test of an elevator is modified from the original C-type test items (if data inspection is not questioned, qualification can be confirmed) into B-type test items (not only data is inspected, but also field inspection is carried out on the items), other tests in the test can be carried out only if the results of the balance coefficients accord with the back side, and the test items of the balance coefficients are added in the regular inspection. Therefore, in order to reduce human influence, improve the measurement accuracy and the work efficiency of the elevator balance coefficient, and reduce the economic cost (the load loaded in the car and the labor cost for carrying) of an installation unit or a use unit, it is necessary to research a no-load measurement method which has high measurement accuracy, simple installation, high work efficiency and small influence of human factors.
