Clamp loading and unloading device for large diameter deep sea simulator

Abstract

A hoop detaching device for a large-diameter deep-sea simulator comprises a circular hoop, wherein the circular hoop consists of four hoop sections; each hoop section has a quadrant structure and is provided with a translation oil cylinder; a piston rod of each translation oil cylinder is hinged to the outer peripheral surface of the corresponding hoop section; the translation oil cylinders are used for driving the four hoop sections to be closed or opened; at least three vertical fine-adjusting oil cylinders are arranged below each hoop section; at least one fine-adjusting oil cylinder is arranged on each of two sides of the gravity center of each hoop section; cylinder bodies of the fine-adjusting oil cylinders are fixedly arranged on a vehicle frame; piston rods of the fine-adjusting oil cylinders are connected with connecting seats; upper end surfaces of the connecting seats cling to lower end surfaces of the hoop sections; the vehicle frame can be movably supported on tracks through wheels; the extending direction of each track is parallel to the translation direction of the corresponding hoop section; and the translation oil cylinders and the tracks are fixedly supported on a foundation. By using the hoop detaching device, a hoop, particularly a large-diameter hoop, can be automatically detached, and the mounting precision and the work efficiency are improved.

Description

technical field [0001] The invention relates to deep-sea simulation test equipment, in particular to a pressure cylinder in the deep-sea simulation test equipment, in particular to a clamp assembly and disassembly device applied to a vertical pressure cylinder. Background technique [0002] The pressure cylinder is the key equipment in the deep-sea simulator, which is used to simulate the pressure environment of deep-sea seawater. It is usually sealed with a forged steel-clamp structure, and its full-section large opening can maximize the use of the space of the pressure cylinder and save construction costs. The clamps of the old deep-sea simulators are usually assembled and disassembled in the form of crane hoisting. When the clamps are installed, the cranes lift the clamps, and the position of the clamps is adjusted through manual and crane cooperation. After the clamps are adjusted in place, The crown block provides a side force to the clamp to make it engage with the cyl...

AI Technical Summary

Problems solved by technology

This traditional assembly and disassembly method has the following defects: First, due to the low precision and large range of movement of the crane, it is impossible to fine-tune the position of the clamp; second, when the clamp is installed, manual assistance is required to control the movement of the clamp. When the weight and scale of the clamp are large, the movement of the clamp can no longer be controlled manually; third, when the clamp is disassembled, it is necessary to use a crane to separate the clamp from the cylinder, but when the cylinder and the clamp are clamped When it is dead, due to the limitation of the load of the crane and the space position, it is necessary to use other equipment to remove the clamp
