Embodiment Construction
[0026] The extracting device designed by the invention can conveniently take out large-scale workpieces of equal weight from the cylinder-adjustable rice-shaped support.
[0027] Such as figure 1 , figure 2 As shown, the extraction device includes a plurality of groups of trolleys installed on the rice-shaped support 70, and each group is provided with a symmetrical left trolley 10 and a right trolley 20. Taking the left car 10 as an example, it includes a side 1, a hypotenuse 2 and a bottom 3 connected to form a right-angled triangle frame structure, and a wheel 5 is installed on the bottom fixed part 4 provided below the bottom 3; The side 1 , hypotenuse 2 , bottom 3 , bottom fastening portion 4 and wheels 5 included in the vehicle 20 are arranged in a similar manner.
[0028] Such as image 3 As shown, the left car 10 in each group contacts the left side of the rice-shaped support 70, and the right car 20 contacts the right side of the rice-shaped support 70; so that th...

The invention relates to a fetching device and a fetching method for an umbrella-shaped support inside a barrel. Multiple groups of trolleys are mounted on the umbrella-shaped support; each group of trolley is provided with a left trolley and a right trolley which are symmetrical; each trolley comprises a side edge, an oblique edge, a bottom edge, a bottom fixed connection part and a wheel, wherein the side edge, the oblique edge and the bottom edge are connected into a right triangle frame, the bottom fixed connection part is arranged under the bottom edge, and the wheel is mounted on the bottom fixed connection part; and the wheels are in contact with the inner wall of the barrel at the outer side of the umbrella-shaped support, so that the umbrella-shaped support can be pushed out from the barrel. The fetching device has the advantages that the installation is simple; the operation is convenient; time and labor are saved; the labor intensity of a worker is greatly reduced; the safety is very high; and the universality is wide. The movement difficulty of a large-sized and heavy-type workpiece can be reduced by virtue of rolling friction of the wheels on the barrel of a pressure container; and the height is adjusted by eccentric wheels, so that the phenomenon since the workpiece is inclined, the movement is blocked is avoided.
Description
technical field [0001] The invention relates to the field of nuclear power pressure vessels, in particular to an extraction device and an extraction method for a rice-shaped support inside a cylinder. Background technique [0002] The inside of the cylinder of the nuclear power pressure vessel is equipped with a cylinder-adjustable rice-shaped support. Usually the cylinder adjustable rice support is located at a depth of 10m-15m inside the cylinder and weighs 5358.6kg, so it is very difficult to take out the cylinder adjustable rice support after use. In the current method, it is generally necessary to erect the cylinder and then use a crane to lift it, which is time-consuming and labor-intensive, and the safety is not high. Moreover, under the long situation of cylinder body, it is difficult to stand up, and the operation is very troublesome. Contents of the invention [0003] The purpose of the present invention is to solve the problem of difficulty in taking out large...
