Description

Adjustable square steel installation top support device

technical field

The utility model relates to a support device for a cable bridge frame of a nuclear power plant, more specifically, the utility model relates to an adjustable square steel installation top support device.

Background technique

The nuclear-grade cable tray is used for laying and installing the signal transmission and power cables of nuclear-grade equipment. Its installation quality and stability play a decisive role in ensuring the reliable operation of nuclear-grade equipment. During the installation of nuclear cable trays in the nuclear island building of a nuclear power plant, the square steel as an important support for the cable trays is a key factor affecting the overall installation quality of the nuclear cable trays.

Please refer to Figure 1, as one of the key components of the nuclear-grade cable tray, the square steel is mainly used to fix the tray arm and support the cable tray to ensure the reliability of the nuclear-grade cable channel. According to the overall layout of the core-level bridge frame of the nuclear island workshop of the nuclear power plant, the square steel is connected by welding or expansion bolts, and is generally installed on the top of the room. important influence. Because the square steel is made of galvanized steel, its quality is generally heavy (heavier than 50kg), and the safety risk is relatively high during installation, and there is a danger of falling. Therefore, it is necessary to focus on the square steel support method, support stability and reliability, and safety risk prevention for high-altitude operations during installation.

Usually, during the installation of nuclear-grade square steel in nuclear power plants, the temporary support of the square steel during installation is realized by setting hydraulic jacks on the portal frame. In general, the height of the square steel in the installation area varies, and the adjustable height of the jack is limited. In many cases, it is necessary to add multiple layers of wood between the portal frame and the hydraulic jack. Due to the small contact surface between the top of the jack and the square steel, the bottom and the wooden square, the overall stability is poor; During this period, it is very easy to cause the square steel to tilt or fall due to uneven force, causing safety accidents; therefore, usually considering safety risks and welding quality assurance, 2-3 additional people will be arranged to support; but for relatively narrow areas, manpower It is very difficult to adjust and temporarily fix, and it is necessary to prevent burns from welding slag. In addition, for the square steel fixed by welding, the reliability and stability of the artificial fixing method are poor, which will not only affect the operation of the welder during welding, but also further affect the welding quality (during welding, the shaking of the square steel or the horizontal force will reduce the will affect the welding quality).

In view of this, it is necessary to provide an adjustable square steel installation top support device to solve the problems of stability, operability, adjustability and support safety of the temporary support during the installation of square steel.
