Embodiment

[0032] see figure 1 , a loading system for an elevator load test, including a support frame 1, a water tank, a weighing device 3 and a water supply and return device 4. The support frame 1 is provided with an elastic support 11 , and the water tank is placed on the elastic support 11 . During specific implementation, a pulley with a locking structure is provided below the support frame 1 to facilitate the movement of the support frame 1 .

[0033] The water tank includes a limiting frame 21 open above and a telescopic water bag 22 located in the limiting frame 21 . The limit frame 21 is placed on the elastic support member 11 of the support frame 1 . see figure 2 and image 3 , during specific implementation, the limiting frame 21 includes a bottom plate, four right-angle fixing pieces 211 and four clamping plates 212 . The right-angle fixing parts 211 are fixed at the four corners of the bottom plate, and each side has a slot. The clamping slot runs through the right-a...

Abstract

The invention discloses a loading system and a loading method for elevator load tests. The loading system comprises a support frame, a water tank, a weighing device and a supply and return water device, wherein an elastic support piece is arranged on the support frame; the water tank is arranged on the elastic support piece; the weighing device is positioned between the support frame and the watertank; the elastic force provided by the elastic support piece is consistent with the gravity of the water tank, and a gap is reserved between the water tank and the weighing device under the action of the elastic support piece; the top and the bottom of the water tank are respectively provided with a water inlet and a water outlet, and the water inlet and the water outlet are respectively connected with the supply and return water device through an inlet pipe and an outlet pipe; when the water tank is filled with water, the water tank can be pressed on the weighing device and is weighed by the weighing device. The loading system can realize continuous loading, is rapid and accurate in loading, and improves the efficiency and accuracy of elevator load tests.

Description

technical field [0001] The invention relates to the technical field of elevator tests, in particular to a loading system and a loading method for elevator load tests. Background technique [0002] With the vigorous development of the real estate industry, the elevator industry is also developing rapidly. In order to ensure that each elevator can run accurately and stably, it is necessary to test the newly installed elevator, the most important of which is the load test. The elevator load test includes: (1) Balance coefficient test: when the car and the counterweight run to the same position, the car load is 0%, 25%, 40%, 50%, 75%, 100%, 110%, use The clamp meter measures the current, and the balance factor obtained must meet the standard requirements of the elevator. (2) Static load test: When the car is loaded with 150%, stand still for 10 minutes, and the traction rope will not slip. [0003] At present, the elevator load test on the market is mainly the counterweight i...
