Embodiment Construction

[0030] In order to better understand the present invention, the content of the present invention will be further described below in conjunction with the accompanying drawings.

[0031] like figure 1 As shown, the electromagnetic load sudden release device 2 provided by the present invention includes a coaxial suspension ring 4, an electromagnetic device, a wedge 10 and a load assembly;

[0032] The top of the suspension ring 4 is connected to the test frame 1, and the bottom is connected to the square casing 5 of the electromagnetic device. Below, and through the return spring 7 to connect the electromagnet 8 located directly above the interlayer, the sucker 6 is provided with a connecting rod passing through the return spring 7 and the electromagnet 8, and the center of the interlayer is provided with a hole for the wedge 10 to pass through. The block 10 is fixedly connected to the suction cup 6 through a connecting rod.

[0033] The load assembly includes: a jaw rotating s...

Abstract

The invention discloses an electromagnetic sudden load release device which is characterized in that a test rack is connected above the device in the vertical direction, a weight block is connected below the device, and the device sequentially comprises a hanging ring (4), an electromagnetic device, a wedge block (10) and a load assembly which are coaxially arranged; the electromagnetic device islocated below the hanging ring (4) and remotely controls the wedge block (10) to move up and down so that the load assembly is driven to be locked or released, and the device is high in controllability and novel and reliable in structure.

Description

technical field [0001] The invention relates to a load test device, in particular to an electromagnetic load sudden release device. Background technique [0002] With the increasing importance of safe production, various test equipment or tools need to carry out corresponding static load tests before application, that is, the impact load of test equipment or tools actually bears the impact load in use, which is to simulate the test equipment or tools. In the actual working condition of the appliance, the sudden load release device is widely used in the static load test. [0003] For example, in the power industry, ultra-high molecular weight polyethylene fiber ropes and polyester fiber ropes are widely used. For example, braided fiber ropes are used as dragging ropes or guide ropes in construction wiring operations; The fiber rope is used as the load-bearing cable and braided rope of the suspension spanning frame, and the dynamic mechanical properties of the fiber rope need...
