Description
Technical Field
The utility model relates to a special equipment detects technical field, specifically is a water counterweight.
Background
From 2017, 10, 1, relevant departments need to regularly inspect dragging and forced passenger elevators and firefighter elevators which are used for 5 years or more and are qualified in installation supervision and inspection according to the requirements of brake test projects in new-edition inspection regulations. In the measuring process, the lift car is respectively loaded with 30%, 40%, 45%, 50% and 60% of rated load capacity to carry out the whole upper and lower running. Determining the balance coefficient of the elevator to be between 0.40 and 0.50 or meet the design value of a manufacturing unit, and loading the balance coefficient to 125 percent of rated load.
In the prior art, when carrying out elevator balance coefficient experiment and 125% load experiment, will carry a large amount of metal system weights, it is huge to operating personnel work load, extravagant a large amount of manpowers. And when loading the weight in to the elevator, because the weight of metal system is harder coarse, and piles up in the car usually and put the use, cause damage and scratch to being surveyed elevator car easily.
After one set of weight is used for a long time, because of the wearing and tearing of many times transport, can make the weight alleviate usually, can not reach the weight of demarcation, cause elevator balance coefficient experiment and 125% load experiment result inaccurate after the accumulation, cause the elevator balance coefficient lower, constitute the threat to the safety of elevator, even take place accidents such as elevator squat the end.
The water weight with unit weight is selected for measurement, so that the problem that the accuracy is influenced by the abrasion of the metal weight can be avoided. If the traditional soft water bag is used, the water bag is easy to deform after water is injected, the whole water bag is accumulated at the bottom, the water bag bears larger water pressure, and the irregular shape also extrudes the bottom of the lift car, so that the safety performance of the lift car is influenced. The common hard water tank has a simpler structure, the whole shape is mostly a cylinder, and the bottom is mostly a plane or a fixed bracket; such water weight structure removes the flexibility relatively poor, though can alleviate the water pressure of bottom to a certain extent, nevertheless does not match with the inner space of car, is difficult to put and remove during the use. If be equipped with many elevators in same building, when the change waits to detect the elevator, keep inside the water removal that fills with of soft water bag or stereoplasm water tank to make the intensity of labour of transport show and increase, and adopt artifical method of empting, refilling also can cause the waste of water resource and the extension of repair time, holistic work efficiency is lower. There is therefore a need for an elevator load test measuring tool that is capable of accurate measurement and flexible movement.
