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 follow-up brake device, which mainly consists of a mechanical structure part and an electric control part, wherein the mechanical structure part comprises a balancing weight and a brake mechanism, the balancing weight and the brake mechanism are detachably connected together by a bolt to form an integral counterweight, and the electric control part is used for detecting a locking signal when an unfolding mechanism is unfolded to the proper position, and controlling the brake mechanism to quickly brake, so as to realize the quick-brake function, reduce the influence on the locking by the movement of the counterweight, and release the brake state after certain delay. The device has the advantage that the requirements of simulation of a zero-gravity environment of the ground unfolding test of the unfolding mechanism, quick braking at instantaneous locking, and energy consumption of the counterweight are met.

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...
