Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0024] Figure 1 to Figure 5 As shown, the counterweight accompanying braking device provided by the present invention includes two major parts of mechanical structure and electrical control. The upper top plate connecting bolts 8 are connected together to become a whole balance weight. Therefore the weight of the counterweight consists of a fixed part (quick brake) and an adjustable part (counterweight).

[0025] The counterweight 1 is a steel sheet with the same cross-section, and through the ...

Abstract

The invention provides a counterweight accompanying braking device, which is mainly composed of a mechanical structure and an electrical control part. The mechanical structure part includes a counterweight and a braking mechanism. It can be detachably connected together to form an integral balance weight. The electrical control part detects the locking signal that the deployment mechanism is deployed in place, and controls the brake mechanism to brake quickly to realize the rapid braking function, so as to reduce the impact on the lock caused by the movement of the balance weight. influence, and release the brake status after a certain time delay. The device of the invention can realize the "zero-gravity environment" simulation of the ground deployment test of the deployable mechanism and the requirement of fast braking at the moment of locking to consume the energy of the balance weight.

Description

technical field [0001] The invention relates to an on-orbit deployment of a simulated satellite, and more specifically relates to a counterweight accompanying braking device. Background technique [0002] In order to simulate the on-orbit deployment process of the satellite, verify the deployment performance of the deployable mechanism, and ensure the safety and reliability of its on-orbit deployment, it is necessary to conduct sufficient deployment experiments on the ground. The main difference between ground deployment and on-orbit deployment is the effect of gravity. Therefore, when launching tests on the ground, a "zero-gravity environment" must be established. [0003] The existing deployment test methods mainly generate a "zero-gravity environment" through air flotation and vertical suspension. In order to establish a "zero-gravity environment", the deployable mechanism needs to be balanced by connecting the balance weight with a wire rope, and the balance weight mov...
