Embodiment Construction

[0019] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Image 6 As shown, a main pressure distribution valve maintenance hanger,

[0020] The hanger is composed of an upper lifting bracket and a lower base, and the upper lifting bracket and the lower base are connected by connecting bolts 3 to form a whole;

[0021] In the upper lifting bracket, the cross-section is triangular and the vertical section is square. The beam 2 at the upper end of the bracket 6 is provided with lifting lugs 1, and a plurality of connecting bolts 3 are installed at the bottom of the bracket 6;

[0022] In the lower base, a fixed frame 8 is arranged in the middle part of the "n" type frame body 7 matched with the bottom of the bracket 6, and a plurality of vertical rods 9 are fixedly installed on the lower part of the fixed frame 8 to form a lower rectangular frame 10 together with the fixed frame 8. The bottom of the bar 9 is provided with a draw-in slot 11 equipped with a lat...

Abstract

The invention discloses an overhauling hanging bracket for a main distributing valve. The hanging bracket is composed of an upper hoisting support and a lower base. The upper hoisting support and the lower base are connected into a whole through connecting bolts. A lifting lug is arranged on a beam at the upper end of a support with the triangular cross section and the square longitudinal section in the upper hoisting support, and a plurality of connecting bolts are arranged at the bottom of the support. In the lower base, a fixing frame is arranged in the middle of an n-shaped frame body matched with the bottom of the support, a plurality of vertical rods are fixedly arranged at the lower portion of the fixing frame, and a lower rectangular frame is jointly formed through the vertical rods and the fixing frame. Clamping grooves with bolts are formed in the bottoms of the vertical rods, and the two ends of a cross rod are matched with the clamping grooves. According to the overhauling hanging bracket for the main distributing valve, the problems that no special tool for dismounting an upper end cover of a main distributing valve exists, and dismounting is difficult are solved, overhauling of the main distributing valve is successfully achieved, and manpower is saved.

Description

technical field [0001] The invention relates to a hoisting device for inspection and maintenance of a speed regulation system of a hydropower station, in particular to an inspection hanger used for a main pressure distribution valve of the speed regulation system of a hydropower station. Background technique [0002] The opening of the main pressure distribution valve of the speed control system of Xiangjiaba Hydropower Station is 250mm, which is the one with the largest flow rate and volume among the existing domestic pressure distribution valves. When the main pressure distribution valve is overhauled, the upper end cover of the main pressure distribution valve needs to be removed. Remove the main pressure distribution valve piston and bushing. At present, when dismantling the above-mentioned equipment, there is no special tool, and it can only be taken out by lifting. The weight of the upper end cover of the main pressure distribution valve is about 50Kg, the weight of th...
