Movable extending-and-contracting control method for electrical equipment support in underground comprehensive pipe gallery

Abstract

The invention relates to a movable extending-and-contracting control method for an electrical equipment support in an underground comprehensive pipe gallery. The electrical equipment support is arranged in the underground comprehensive pipe gallery so that a fixing rod can move in a horizontal sliding rail along with walking wheels or can be located and stops moving; and the height of the equipment is adjusted by adjusting the distance between the portion, inserted into a front rod, of any level of extending-and-contracting rod behind the fixing rod and the front rod; a sector-shaped fixing pin is inserted into a sector-shaped pin hole aligned with the sector-shaped fixing pin in the radial direction to connect every two adjacent rods, and loosening and falling of the sector-shaped fixing pins are limited doubly through hasps and locking sleeves; and within the extending-and-contracting length range of locking sleeve extending-and-contracting joints, covering of the sector-shaped pin holes in the all the levels of connected rods, exposure of the fixing pins and hiding of two stations can be achieved. According to the movable extending-and-contracting control method, all the levels of rods serve as cable penetrating pipes for input and output of cables of the electrical equipment, a cable winding frame is arranged on the sliding rail, and the cable supporting function and the cable winding, unwinding, extending and contracting functions are achieved. According to the movable extending-and-contracting control method, the height and plane position can be adjusted through longitudinal extending and contracting and translation, and the method is especially suitable for electrical equipment mounting under the condition that the space is narrow or the operation position needs to be changed frequently.

Description

technical field [0001] The invention relates to an electrical equipment support, in particular to a movable telescopic control method for the electrical equipment support in an underground comprehensive utility gallery. Background technique [0002] In engineering applications, electrical equipment often adopts a fixed installation method, which is installed on various types of steel or fixed on walls and cylinders. Considering the convenience of personnel operation, the installation height of electrical equipment is often between 1.2 and 1.5m. However, in places such as various tunnels with narrow spaces, or because of the narrow passage itself or the centralized installation of electrical equipment, it is sometimes difficult to meet the space or personnel operation requirements for fixed installation of electrical equipment. For example, when the installation location of electrical equipment needs to occupy the passage of personnel or equipment, the installation height of ...
