Pressure vessel detection auxiliary device

Abstract

The utility model relates to the technical field of pressure vessel detection, in particular to an auxiliary device for pressure vessel detection. In order to solve the problems that time and labor are consumed and the structure is unstable when a traditional pressure vessel detection auxiliary device is used for detecting a pressure vessel in a direction changing mode, the novel pressure vessel detection auxiliary device is provided and comprises a base, two side blocks and two arc-shaped clamping blocks used for clamping the pressure vessel. The two side blocks are connected with clamping blocks through hydraulic cylinders, and the two arc-shaped clamping blocks are arranged on the top face of the base in a bilateral symmetry mode through clamping assemblies. The relative positions of the two clamping blocks are changed through cooperation of the hydraulic cylinders and the clamping blocks, and clamping and fixing of the pressure container in the horizontal state are achieved. When the pressure vessel needs to be clamped and fixed in a vertical state, the pressure vessel is slightly lifted by using a crown block and the direction of the pressure vessel is changed, and then the two arc-shaped clamping blocks are driven by the clamping assembly to move in a relatively closed manner, so that the pressure vessel can be clamped and fixed in the vertical state.

Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessel detection, in particular to a pressure vessel detection auxiliary device. Background Art

[0002] During the manufacturing process and before being put into use, pressure vessels need to undergo various tests, including structural testing, appearance and geometric dimension testing, non-destructive testing, pressure-resistant sealing testing, and leakage testing. When testing pressure vessels, they are usually placed on corresponding auxiliary devices to ensure the stability and comprehensiveness of the pressure vessels during testing.

[0003] The traditional pressure vessel inspection auxiliary device is similar to the saddle support of the container. When it is used, the pressure vessel and the auxiliary device need to be placed in a suitable orientation for inspection. When the inspection orientation needs to be changed, such as changing the pressure vessel from vertical to horizontal or from horizontal to vertical, the pressure vessel needs to be lifted by an overhead crane to change its orientation, and the placement of the auxiliary device needs to be readjusted before the pressure vessel can be lifted back onto the auxiliary device for use. The process requires lifting the pressure vessel back and forth and rearranging the auxiliary device manually or with the help of a crane, which is time-consuming and labor-intensive. At the same time, the auxiliary device can only provide a simple support for the pressure vessel and has an unstable structure. Summary of the invention

[0004] The utility model provides a new pressure vessel inspection auxiliary device to solve the problems that the traditional pressure vessel inspection auxiliary device is time-consuming, labor-intensive and structurally unstable when inspecting the pressure vessel with the orientation changed.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] A pressure vessel inspection auxiliary device, comprising a base with an accommodating cavity therein, two side blocks respectively fixed to the left and right ends of the top surface of the base, and two arc-shaped clamping blocks for clamping the pressure vessel, the two side blocks are connected to clamping blocks that can move left and right through hydraulic cylinders on opposite sides of the two side blocks, and the two arc-shaped clamping blocks are symmetrically arranged at the middle of the top surface of the base through a clamping assembly;

[0007] The clamping assembly includes a square open ring bracket located in the accommodating cavity and distributed on both ends thereof, a strip slide arranged along the left and right directions in its length direction, two inner movable rods, two outer movable rods, two inner sliding columns, two outer sliding columns, a lead screw arranged along the front and back, and a threaded sleeve adapted to the lead screw, the strip slide and the two inner movable rods are all located in the square open ring bracket, the two inner sliding columns are all slidably connected to the strip slide, both ends of the square open ring bracket are fixed with vertically arranged movable shafts, one end of the two inner movable rods are respectively rotatably connected to the two movable shafts, the other ends of the two inner movable rods are respectively rotatably connected to the two inner sliding columns, the two outer movable rods are both located outside the square open ring bracket, and one end of the two outer movable rods is respectively rotatably connected to the two movable shafts, The two outer sliding columns are slidably connected to the travel holes left and right, and the middle parts of the two arc-shaped clamping blocks are respectively fixed to the two outer sliding columns. The threaded sleeve is fixed on the square open ring bracket and is located on the side of the strip slide away from the open end of the square open ring bracket. The lead screw is connected to the threaded sleeve and one end of the lead screw located in the square open ring is rotatably connected to a side of the strip slide close to the threaded sleeve through a bearing. The other end of the lead screw extends outward from the base and the other end of the lead screw is rotatably connected to the base through a bearing.

[0008] Working principle: Place the pressure vessel horizontally on the top surface of the base, where the two arc-shaped clamping blocks are equivalent to cushion blocks to support the pressure vessel, which is convenient for placing the pressure vessel. The two clamping blocks move toward each other under the action of the hydraulic cylinder to achieve the clamping and fixing operation of the pressure vessel. At this time, the pressure vessel is in a horizontal state; when it is necessary to perform a vertical state inspection on the pressure vessel, use a crane to slightly lift the pressure vessel and change its orientation, then place the pressure vessel vertically on the top surface of the base, rotate the lead screw, and the square open annular bracket moves forward. During the movement, the two inner sliding columns of the square open annular bracket are relatively opened, and the two outer sliding columns are relatively closed, thereby driving the two arc-shaped clamping blocks to close relatively, thereby achieving the clamping of the vertical pressure vessel, so as to facilitate the vertical inspection of the pressure vessel.

[0009] Furthermore, rubber pads are provided on the opposite surfaces of the two arc-shaped clamping blocks, which facilitate better clamping of the pressure vessel and also play a protective role when clamping the pressure vessel, preventing the arc-shaped clamping blocks from scratching the pressure vessel and affecting the overall quality of the pressure vessel.

[0010] Furthermore, a rotating handle is fixed to the portion of the other end of the lead screw that extends outward from the base to facilitate the screwing of the lead screw.

[0011] The beneficial effects produced by the utility model are as follows: through the cooperation of the hydraulic cylinder and the clamping block, the relative positions of the two clamping blocks are changed, so that the pressure vessel to be inspected in a horizontal state can be clamped and fixed; when the pressure vessel needs to be clamped and fixed in a vertical state, it is only necessary to use the overhead crane to slightly lift the pressure vessel and change its orientation, and then the clamping assembly drives the two arc-shaped clamping blocks to move relatively closed, so that the pressure vessel can be clamped and fixed in a vertical state, without the need to lift the pressure vessel back and forth, and without the need to place the auxiliary device manually or by a crane, and the auxiliary device can also clamp the pressure vessel, making the pressure vessel more stable.
