DETAILED DESCRIPTION

[0024] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0025] like Figures 1 to 5 As shown, a positioning structure for pressure vessel and pressure pipeline inspection control includes a mounting base plate 1, on which five first telescopic cylinders 2 and a plurality of columns 3 arranged in a row are mounted, the first telescopic cylinder 2 is a single-stroke telescopic cylinder, a limit plate 4 is mounted on the top of the column 3, and a limit hole 5 sleeved on the first telescopic cylinder 2 is opened at a position corresponding to each first telescopic cylinder 2 on the limit plate 4.

[0026] A lifting bracket 6 is installed at the top of the piston rod of the first telescopic cylinder 2. The cross-section of the lifting bracket 6 is "T"-shaped. Four guide rods 7 arranged in a circular array are installed at the bottom of the lifting bracket 6. Four guide holes 8 arranged in a circular array are opened on the limit plate 4 around each limit hole 5. The guide rods 7 are inserted into the guide holes 8 from top to bottom.

[0027] An L-shaped support frame 9 and a second telescopic cylinder 10 are hinged on the lifting bracket 6 . The second telescopic cylinder 20 is a double-stroke telescopic cylinder. The piston rod end of the second telescopic cylinder 10 is hinged to the outer side surface of one of the right angles of the support frame 9 . The specific articulated structure is as follows: two symmetrical first articulated blocks 11 are provided on the top of the lifting bracket 6, and a second articulated block 12 is fixedly connected to the outer side of the intersection of the two right-angled sides of the support frame 9, the second articulated block 12 is located between the two first articulated blocks 11, and the second articulated block 12 is articulated with the two first articulated blocks 11 through a first rotating shaft 13; a third articulated block 14 is fixedly connected to the lifting bracket 6, a fourth articulated block 15 is installed at the bottom end of the second telescopic cylinder 10, and the third articulated block 14 and the fourth articulated block 15 are articulated through a second rotating shaft 16; a fifth articulated block 17 is installed at the end of the piston rod of the second telescopic cylinder 10, and a sixth articulated block 18 is fixedly connected to the outer side surface of one of the right-angled sides of the support frame 9, and the fifth articulated block 17 and the sixth articulated block 18 are articulated through a third rotating shaft 19.

[0028] A rotary clamping cylinder 20 is respectively installed on the outer side surfaces of the two right-angled sides of the support frame 9, and a pressure plate 21 is installed on the rotating block of the rotary clamping cylinder 20. The cross-section of the pressure plate 21 is a "concave" shape, and a rubber sleeve 22 is covered on the end of the pressure plate 21 away from the rotary clamping cylinder 20. During the rotation of the pressure plate 21, the rubber sleeve 22 can prevent the pressure plate 21 from directly colliding or scratching with the pressure vessel and pressure pipeline, thereby avoiding damage to the pressure pipeline and pressure vessel.

[0029] A layer of rubber pad 23 is pasted on the inner side of the support frame 9. The rubber pad 23 has the functions of buffering, shock absorption and scratch prevention, so as to prevent the pressure vessel pressure pipeline from colliding and rubbing with the support frame 9; the two right-angled sides of the support frame 9 are both in the shape of a "convex" character, and the protruding part in the middle of the end of the right-angled side of the support frame 9 is convenient for connecting with the conveying equipment on both sides, and the notched parts at the two corners of the end of the right-angled side of the support frame 9 provide space for the movement of the rotating clamping cylinder 20 and the pressure plate 21.

[0030] Taking the positioning of pressure pipes as an example, the working process of this positioning structure is introduced:

[0031] 1. The second telescopic cylinder is fully retracted, the right angle side of the support frame and the second telescopic cylinder is hinged in a horizontal state, and the pressure pipe 100 is rolled onto the support frame;

[0032] 2. The second telescopic cylinder is extended to the end of the first stroke, so that the opening of the support frame is vertically upward;

[0033] 3. Rotate the rotary pressing cylinder 90 degrees in the positive direction to press the rubber sleeve onto the pressure pipe and clamp the pressure pipe in cooperation with the support frame;

[0034] 4. The staff uses the detection equipment to detect the pressure pipe. When encountering a group of support frames and rubber blocks blocking it, the rotary pressing cylinder rotates 90 degrees in the opposite direction to separate the rubber sleeve from the pressure pipe. The first telescopic cylinder contracts to separate the support frame from the pressure pipe. At this time, the pressure pipe is clamped by the remaining groups of support frames and rubber blocks.

[0035] 5. After the pressure pipeline is inspected, the second telescopic cylinder is extended to the end of the second stroke, so that the right angle side where the support frame and the second telescopic cylinder are hinged is in a vertical state, and the pressure pipeline is rolled out from the other right angle side of the support frame.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
