Description

Weight set for elevator load test
Technical Field
The utility model relates to a special equipment detects technical field, specifically is a weight group for elevator load test.
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 a brake test project in a new edition inspection standard. 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 a set of metal weight is used for a long time, the weight mass can be usually lightened due to the abrasion of multiple times of carrying, the calibrated weight cannot be reached, the results of an elevator balance coefficient experiment and a 125% load experiment are inaccurate after accumulation, the elevator balance coefficient is low, the safety of an elevator is threatened, and even accidents such as the squat bottom of the elevator occur.
Therefore, the weight of the water is selected as the weight to carry out the elevator load test, the weight of the weight is adjusted through the water injection and drainage processes, and an operator only needs to carry the empty water storage measuring device to enter and exit the elevator car, so that the labor intensity is reduced to a certain extent, and the problem that the precision is influenced by the metal weight due to abrasion is 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. For example, the elevator water simulation load device of patent application No. 201922258938.4 includes an outer shell made of flexible waterproof material and water filled in the outer shell, and a filler for adjusting weight is arranged in the outer shell, so that the elevator water simulation load device is convenient to store and carry and can carry out an elevator load test more flexibly; however, a plurality of water bags are required to be stacked during testing, and the water bags are easy to damage due to extrusion; the shell is thick and is not easy to fold, and the labor intensity is not reduced; under the low-temperature environment, the material state of the water bag changes, and the water bag is not easy to fold, so that the water bag is inconvenient to carry; in addition, the flexible material is used as a water bag, the shape of the water bag is changed after water is injected, water is accumulated at the bottom, the water pressure at the lower part is high, the adjacent car walls are squeezed, and therefore the car side walls are easy to deform.
Ordinary stereoplasm water tank structure is comparatively simple, and whole shape is mostly the cylinder, and the mobility is relatively poor, though can alleviate the water pressure of bottom to a certain extent, nevertheless mismatch with the inner space of car, and operating personnel is difficult to put and remove this type of water tank in elevator load test's the use.
SUMMERY OF THE UTILITY MODEL
The utility model particularly relates to an elevator is weight group for load test has solved inconvenient, the inaccurate problem of measurement weight transport in the elevator load test.
In order to solve the technical problem, the utility model provides a technical scheme does: a weight set for elevator load test comprises a plurality of water tanks, wherein the water tanks are hard prismatic hollow shells, exhaust holes are formed in the upper parts of the water tanks, and water gaps and support frames are fixed at the bottoms of the water tanks; and a reinforcing structure is arranged on the side wall of the water tank.
