Embodiment 1

[0041] to combine figure 1 , the present invention is based on a six-link parallel mechanism with multi-directional impact isolation capabilities, and is mainly composed of a platen 1, a base 4, six impact isolators 3, a hinge support 2, and a pin 5. The platen is located on the upper part for equipment placement, and the shape and installation interface can be changed according to the needs of different equipment. The base is used to connect with the hull, and the installation point on the hull is connected with the base through the stepped hole 4-1. The shape and installation interface of the base can be changed according to different conditions of use.

[0042] The platen 1, the base 4 and the impact isolator 3 are connected by a Hooke hinge. Hooke hinge is made up of hinge support 2, the first bearing seat 1-1 on the platen 1, the second bearing seat 4-2 on the base 4, bearing pin 5 and bearing. The upper and lower six Hooke hinges are paired in pairs to form a group to ...

Abstract

The invention discloses a clamp slot cut-off anti-disturbance shock isolation platform, belongs to the technical field of anti-shock, and particularly relates to a clamp slot cut-off anti-disturbanceshock isolation platform for protecting precision instruments and equipment of ships. The clamp slot cut-off anti-disturbance shock isolation platform is based on a six-bar parallel mechanism, and hasthe capability to isolate shock in multiple directions. The clamp slot cut-off anti-disturbance shock isolation platform includes a platform board used for placing equipment, a base connected with aship, and six shock isolators. The platform board, the base and the shock isolators are connected by hook joints. The cylinder bodies of the shock isolators are elastic, and are internally provided with clamp slots. The clamp slots are matched with pistons to provide a limit cut-off force to meet the anti-disturbance requirement of inertial navigation, radar and other ship-borne measurement and detection equipment during normal work and the cushioning protection requirement under strong impact. The isolation platform is all-metal, and has the advantages of high environmental adaptability, simple mechanism, high reliability, long service life and easy maintenance.

Description

technical field [0001] The invention belongs to the field of anti-shock technology, and in particular relates to a slot cut-off type anti-disturbance shock isolation platform for protecting precision instruments and equipment of ships. Background technique [0002] In order to meet the needs of information warfare, more and more complex combat systems and electronic navigation systems are equipped on ships. Ships will inevitably suffer from the impact of contact explosions and non-contact explosions during combat, causing damage to important equipment on the ship and causing the ship to lose its combat effectiveness. At present, it is generally used to protect shipboard equipment by adding an impact isolator between the installation base and the equipment. For inertial navigation, radar and other measurement and detection equipment, the position accuracy requirements are very high, and even a small disturbance will cause it to fail to work normally for a period of time.
