Description

Bus duct adjustable support

Technical Field

The utility model belongs to the technical field of building electrical engineering, and relates to a hanging bracket for fixing a lower opening type rail type bus duct during installation, in particular to an adjustable bracket for the bus duct.

Background

At present, intelligent computer lab distribution in the building or concentrated illumination electricity consumption position use rail mounted bus duct distribution, rail mounted bus duct adopts the mode of hanging the installation, the lug that adopts jib and busbar upper surface above it is connected, make things convenient for the slip conductive part of bus duct below to remove in parallel with the direction of generating line, this kind of mounting means is when satisfying nimble changeable load and is qualified for the next round of competitions, also bring bus duct gallows fixed mode singleness, current supporting bus gallows can not avoid increasing and decreasing the load or the gallows that the slip is qualified for the next round of competitions to bring leads to the generating line to rock, be difficult to adapt to the accurate regulation of height between two sections rail mounted buses during installation and the use, and the condition that gallows bolt is not hard up. The power consumption danger after the support bolt loosens is obvious, in order to eliminate unsafe hidden danger, satisfies the requirement of stable power supply, and the power distribution advantage of the rail type bus can be exerted by fastening the rail type bus from the side while the power distribution part can slide on the rail.

Disclosure of Invention

In order to solve the stability of the bus duct, the utility model provides an adjustable bracket of the bus duct, which is fastened on the side and vertically hung.

The technical scheme of the utility model is as follows: an adjustable bracket for a bus duct is characterized in that the bus duct is clamped by a U-shaped clamp, the U-shaped clamp is connected with a wire hanging rod and is fastened by a nut, and a spring is arranged between the U-shaped clamp and the wire hanging rod; the U-shaped clamp is composed of a horizontal plate and vertical plates at two ends, the horizontal plate and the vertical plates at two ends are connected into a whole, an upper connecting hole and a lower connecting hole are formed in the vertical plates at two ends, a through wire suspender penetrating hole is formed in the horizontal plate, and a pair of pull-through screw rods are connected between the upper connecting holes of the two vertical plates to realize butt clamping of buses.

The U-shaped clamp is characterized in that two holes are formed in the hanging plates on two sides of the U-shaped clamp respectively, the holes on the upper portion penetrate through the wire drawing rods, the holes on the lower portion are used for penetrating the screw rods on the side edges of the bus, one hole is reserved in the horizontal portion of the clamp, the screw rods penetrate through the adjustable screw rods, and springs penetrate between the screw rods and the U-shaped clamp.

The suspender is a harness suspender, the bottom end of the suspender is provided with a head screw, the upper part of the screw is penetrated with a protection short pipe, a spring is arranged in the short pipe, and a gasket, a spring pad and a nut are used for fastening the U-shaped clamp after penetrating the U-shaped clamp.

The wire drawing rod is a wire passing screw rod, a nut and a gasket can be screwed in, and the wire drawing rod is tensioned after penetrating a preformed hole on one side of the U-shaped clamp close to the bus.

According to the utility model, the rail type bus is hoisted by the U-shaped clamp, the mounting height of the rail type bus can be finely adjusted up and down by adjusting the position of the nut during mounting, the connecting position of two sections of buses is smooth and has no height difference in the sliding or shifting process of the power distribution part, the power supply continuity is ensured when the power distribution part passes through the connecting position, the bus can be clamped by a oppositely-pulled screw rod after the bus is mounted, the impact force is buffered when moving or increasing and decreasing accessories, the bus is held tightly, and the screw rod is prevented from falling off accidentally during shaking.

The utility model can rapidly adjust the elevation at the two ends of the connecting part of the track bus, ensures that the bus duct is firmly hoisted while the power distribution part on the track slides smoothly, ensures the safe power distribution of the track bus, simultaneously avoids the dislocation of the elevation caused by the movement of the power distribution part for many times, automatically adjusts the elevation change in the use process, and improves the reliability of power supply.
