Problems solved by technology

Take the China Spallation Neutron Source CSNS as an example. At present, the size and diameter of special robots after adding radiation shielding are at least 1 meter, and the space for entering the tunnel operation is very limited.
With the rapid development of manipulator technology, for the equipment weighing more than 10 tons in the tunnel, the collimation adjustment operation outside the tunnel, etc., the cantilever distance is at least 4.5 meters, its reliability and accuracy are very low, and the automatic control signal transmission components are relatively resistant to radiation. Weakness results in a very short lifespan. Therefore, it is necessary to explore technical solutions to the above problems.

Embodiment 1

[0043] In this embodiment, a remote ball-and-socket automatic positioning device for equipment in high-radiation areas, such as figure 1 As shown, it includes a matching upper positioning common frame 1 and a lower positioning bottom frame 2. The junction of the upper positioning common frame and the lower positioning bottom frame is in a "T" shape, and three groups of tapered ball socket assemblies 3 are evenly distributed (such as Figure 4 shown), and the upper positioning common frame and the lower positioning base frame are positioned through a tapered ball-and-socket assembly; the opposite sides of the upper positioning common frame are respectively provided with guide assemblies, and the guide assemblies include matching guide rails 4 and guide frames 5 , The guide frame is pre-installed on the inner wall of the tunnel or the installation bracket on both sides of the positioning device, and the guide rail is installed on the upper positioning common frame. Wherein, the ...

Embodiment 2

[0052] This embodiment is a remote ball socket automatic positioning device for equipment in high-radiation areas. Compared with Embodiment 1, the difference is that there is a gap at the junction of the upper positioning common frame and the lower positioning chassis, and the upper positioning The bottom surface of the common frame is also distributed with some downwardly protruding upper auxiliary support platforms 12 (such as Figure 7As shown), the bottom surface of each upper auxiliary support platform is closely connected with the top surface of the lower positioning chassis. In this structure, the lower auxiliary support platform may not be arranged on the lower positioning chassis.

Embodiment 3

[0054] This embodiment is a remote ball socket automatic positioning device for equipment in high-radiation areas. Compared with Embodiment 1, the difference is that there is a gap at the junction of the upper positioning common frame and the lower positioning chassis, and the lower positioning Two upwardly protruding lower auxiliary support platforms are also distributed on the top surface of the underframe, and two downwardly protruding upper auxiliary support platforms 12 (such as Figure 7 As shown), after the upper positioning co-frame and the lower positioning underframe are installed, the upper auxiliary support platform and the lower auxiliary support platform are in one-to-one correspondence and closely connected. In this structure, two auxiliary support platforms and three conical ball-and-socket assemblies located in the upper-level positioning common frame and the lower-level positioning underframe correspond one-to-one to form a supporting structure. The three bea...

Abstract

The invention discloses remotely automatic ball socket positioning device and method. The device comprises an upper-layer positioning common frame and a lower-layer positioning bottom frame matched with each other, wherein the upper-layer positioning common frame and the lower-layer positioning bottom frame are positioned through a tapered ball socket assembly; guiding assemblies are arranged on two opposite sides of the upper-layer positioning common frame; in the guiding assemblies, guiding frames are pre-installed on the tunnel inner walls of two sides of the positioning device or installation supports, and a guide rail is arranged on the upper-layer positioning common frame. The method comprises the steps of pre-installing the equipment on the upper-layer positioning common frame, andpre-installing the guiding frames on the target positions; firstly placing the lower-layer positioning bottom frame at the target position, placing the upper-layer positioning common frame and the equipment at the target positions by adopting a hoisting manner, firstly using the guide rail to downwards slide along the guiding frames so as to carry out preliminary positioning, and then utilizing the tapered ball socket assembly for automatically and accurately positioning. The remotely automatic ball socket positioning device and the method provided by the invention can be applied to remote high-accuracy installation and reset of equipment in a high-radiation area, are suitable for occasions with high risk but requiring equipment overhauling and maintenance, and have higher application values.

Description

technical field [0001] The invention relates to the technical field of remote positioning and installation of equipment in high-radiation areas, in particular to a remote ball-socket automatic positioning device and method for equipment in high-radiation areas. Background technique [0002] In the field of nuclear energy, with the development of the economy and the continuous improvement of the level of science and technology, people pay more and more attention to the safety of environmental operations. The equipment is affected by various factors, such as poor working conditions, equipment manufacturing process and processing defects, poor structural design, and structural aging of the equipment due to long-term operation. Failures inevitably occur, and regular maintenance must be carried out. The dose intensity in these areas is very high, and manual work will greatly increase the radiation dose. It is impossible to go deep into the high-radiation environment to complete i...
