Embodiment Construction
[0022] The technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.
[0023] After the super multi-core flat cable is manufactured, how to determine that the product is qualified and meets the design and use requirements? In addition to the regular full-performance type tests, a number of special type tests must be carried out. Therefore, the construction and implementation of the special type test of the present invention is a very important and indispensable key component of the flat cable.
[0024] Reference figure 1 The flat cable dynamic stability test device of the present invention mainly includes a test tower 1, a winch 2, a mobile trolley 3, a touch proximity switch 4, a signal lamp (not shown in the figure) and a flat cable 5 to be tested. The structure and positional relationship of the above-mentioned components will be described in detail below.
[0025] A plurality of touch proximity switches 4 are i...

The invention discloses a flat type cable dynamic stability testing device and method. The flat type cable dynamic stability testing device comprises a test tower, a winch and a moving trolley. A plurality of touch proximity switches are installed on the inner wall of the test tower, the moving trolley is hung below the winch, a clamp is installed in the test tower, one end of a flat cable is fixed on the clamp, the other end of the flat cable is fixed on the moving trolley, and the flat cable freely droops. The flat type cable dynamic stability testing method includes the following steps of hanging the two ends of the flat type cable, fixing one end, enabling the other end to be movable, enabling a middle section of the flat type cable to freely droop, arranging the touch proximity switches close to the fixed end, enabling the moving end to conduct a round trip in the perpendicular direction, and judging the dynamic stability of the flat type cable according to the triggering conditions of the touch proximity switches. According to the technical scheme, the flat type cable dynamic stability testing device and method can be used for testing the dynamic stability of the flat type cable and conducting a flexing life test.
Description
Technical field [0001] The invention relates to a flat cable detection device and method, and more specifically, to a flat cable dynamic stability testing device and method. Background technique [0002] Due to its special structure, flat cables can be widely used in elevator systems. Since the structure of a flat cable is different from that of an ordinary round cable, its performance and life span will be quite different from that of a round cable. [0003] At present, the total number of cores of the accompanying flat cables for elevators used in civil or commercial buildings with a building height of more than 150m is more than 90 cores. And because the super high-rise and super high-speed elevators with a lifting height of more than 150m and an elevator running speed of 6M / S or more usually use a large car, the U-shaped bending diameter of the super multi-core flat elevator accompanying cable must reach 650mm and above. This requirement cannot be met without using special c...
