Embodiment Construction

[0010] The present invention will be further described below in conjunction with the drawings.

[0011] Reference figure 1 , A screen pitch adjuster, comprising a left fixing seat 1 and a right fixing seat 2. The left fixing seat 1 is fixedly connected to the left internally threaded pipe 3, and the right fixing seat 2 is fixedly connected to the right threaded pipe 4. The thread direction of the left internally threaded tube 3 is opposite to the thread direction of the right threaded tube 4, the left section of the screw 5 is installed in the left threaded tube 3, and the right section of the screw 5 is installed on the right threaded tube 4 Inside, the middle part of the screw 3 is an adjustment handle 6.

[0012] Further, the adjusting handle is a nut, and a through hole for inserting a screwdriver is provided in the nut.

[0013] In this embodiment, the screen pitch adjuster uses galvanized steel as the main component, and its strength meets the force requirements for opening t...

Abstract

A screen distance adjustor comprises a left fixing base and a right fixing base, wherein the left fixing base is fixedly connected with a left inside-threaded pipe, the right fixing base is fixedly connected with a right inside-threaded pipe; the thread direction of the left inside-threaded pipe and the thread direction of the right inside-threaded pipe are opposite; the left section of a threaded rod is arranged in the left threaded pipe, the right section of the threaded rod is arranged in the right threaded pipe, and the middle part of the threaded rod is provided with an adjusting handle. The invention provides a screen distance adjustor which can effectively avoid vibrations and is excellent in reliability.

Description

Technical field [0001] The invention relates to electrical installation engineering of a substation, in particular to a screen pitch installation tool. Background technique [0002] At present, the power installation project lacks effective methods to reduce the vibration caused by the renovation and construction of the screen cabinet. The vibration may cause the protection of adjacent operating screens to malfunction, resulting in a grid trip accident. [0003] The traditional screen cabinet is removed (installed) by direct prying method, using two pry bars to pry one side of the screen to slowly leave (enter) the screen position. During the construction process, because the upper part of the screen cabinet is squeezed by the screen cabinets on both sides, the resistance is large, and the construction effort needs to be increased. Therefore, a lot of vibration will be generated, and the vibration will be transmitted to the adjacent running screen, which is a high safety risk. Sum...
