Anti-explosion sealing structure for integrated heavy cradle head

Abstract

An anti-explosion sealing structure for an integrated heavy cradle head belongs to the field of machine designing and manufacturing and is most used for video monitoring and image tracking. A base, a sealing cover, a middle column, side columns and a side cover form a horizontal operation main body; and a vertical operation box body is of a flat spherical structure and formed by the assembly of modular parts such as a sphere frame, a support piece, a sphere crown, a box cover and the like, wherein the box body can be internally provided with a long focus camera or loaded with other equipment,and all lines are mutually connected inside. By a sealing flange and pressure-resisting oil seal type connection and assembly as well as unique structure design, whole sealing and anti-explosion functions are realized; and air and water are emptied from the inner part, and the inner part is filled with constant-pressure high-purity nitrogen, so that rusting, oxidization, lens mildew stain and fogon a window are effectively prevented and the hidden explosion danger is eliminated; and the working environment and technical property of internal equipment and devices are ensured. The vertical operation box body has all-directional rotating and continuous rotating functions, and the anti-explosion sealing structure is easy to process, assemble and overhaul and suitable to manufacture in batches.

Description

Technical field [0001] The invention relates to an integrated heavy-duty platform explosion-proof sealing structure, which belongs to the field of mechanical design and manufacture, and is mainly used in video monitoring and image tracking. Background technique [0002] At present, the known heavy-duty pan / tilt is mainly composed of horizontal and vertical motion motors, deceleration transmission mechanisms, control circuit boards and pan / tilt housings, and is used to carry telephoto lens cameras, laser ranging, infrared thermal imaging, laser lighting and other sensing equipment. With the development of modern technology, in order to meet the functional and technical requirements of supporting, carrying, integrating various equipment, operation, and control, the heavy-duty pan / tilt has been equipped with a split shield, an outer The wiring structure is overdeveloped towards the integration of pan / tilt, shield, and internal wiring. However, there are many defects in the ex...

AI Technical Summary

Problems solved by technology

However, there are many defects in the existing integrated heavy-duty platform structure, one of which is relatively common: the shell structure is not sealed and is easily affected by environmental factors

When used in an outdoor natural environment, there are often oxygen, high humidity, corrosive gas, flammable gas and dust with static electricity inside the shield shell, resulting in premature aging of the connecting lines, terminal blocks and circuit boards. , damage, corrosion of mechanical parts, moldy coating of precision optical lenses, device function reduction and malfunction, affecting the working stability and service life of the entire system and equipment, and easily causing explosion and deflagration in a flammable gas environment, causing serious harm

The reason for the above-mentioned problems is that the existing integrated heavy-duty pan / tilt structure design is unreasonable, and a long-term effective structural closure cannot be formed after assembly or maintenance.
