Technical Field

[0001] The utility model relates to the technical field of end cap installation, in particular to a fixer used for assembling a slice-type end cap. Background Art

[0002] The head is an indispensable and important component of pressure vessel equipment in many industries from petrochemicals, atomic energy to food and pharmaceuticals. It is a major pressure-bearing component of the pressure vessel. For some large-scale chemical smelting equipment, the required head size is also larger. Due to its large size, and considering transportation and processing reasons, the head will be made into a piece-by-piece type during manufacturing, and then assembled and welded when in use.

[0003] The existing segmented head assembly is connected by a hoist. Since it is difficult to find the position of the segments during the hoisting process, the hoist needs to be constantly adjusted manually, resulting in low assembly efficiency and poor precision. The assembly process is more labor-intensive and the assembly cost is high. Utility Model Content

[0025] Embodiment 1:

[0026] like Figure 1 As shown, a fixture for assembling a sliced ​​head includes a base 1 and a rotating disk 2 rotatably arranged on the base 1; six groups of clamping components are slidably arranged on the rotating disk 2 and are distributed at 60° intervals in a scattered manner, each group of clamping components includes an outer arc clamping plate 23 and an inner arc clamping plate 24 for clamping the slices in cooperation with the outer arc clamping plate 23, a clamping component for fixing its position is provided on the outer arc clamping plate 23, and a sliding component for controlling its sliding to adjust the distance between the inner arc clamping plate 24 and the outer arc clamping plate 23 is provided on the inner arc clamping plate 24; a thickening block for improving its stability is provided on the lower part of the inner wall of the inner arc clamping plate 24;

[0027] The sliding assembly includes a screw rod 22 rotatably arranged at the lower end of the rotating disk 2 and corresponding to the six inner arc-shaped clamping plates 24, and a movable block 25 threadedly sleeved on the screw rod 22; the rotating disk 2 is rotatably connected to the screw rod 22 through a connecting plate provided at the lower end, the right ends of the six screw rods 22 all extend to the outside of the rotating disk 2 and are fixedly sleeved with a hand wheel 221, the six movable blocks 25 all pass through the corresponding slide grooves 21 on the rotating disk 2 and are fixedly connected to the inner arc-shaped clamping plates 24; the outer arc-shaped clamping plates 23 are slidably connected to the corresponding slide grooves 21;

[0028] The clamping assembly includes twelve clamping holes 27 arranged on the rotating disk 2 and located on both sides of the slide slot 21, and a clamping column 231 arranged on the outer arc-shaped clamping plate 23 and used for sliding clamping with the clamping holes 27 on the corresponding side one by one, and a scale is provided on the rotating disk 2 located on the right side of the slide slot 21.

[0029] The working principle of the above-mentioned fixer is: when in use, first adjust the outer arc clamping plate 23 to the corresponding scale clamping hole 27 according to the diameter of the head, and then press the clamping column 231 on the outer arc clamping plate 23 down to make the clamping column 231 engage with the clamping hole 27, and place a slice in a group of clamping components so that the outer side of the slice is restricted by the outer arc clamping plate 23, and rotate the screw rod 22 by the handwheel 221 to drive the movable block 25 to move until the inner arc clamping plate 24 contacts the inner wall of the slice. At this time, the slice is fixed by the inner arc clamping plate 24 and the outer arc clamping plate 23, and then continue to install the next slice into the next group of clamping components until all slices are fixed.

[0030] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that the clamping assembly is an electromagnetic latch disposed on the outer arc-shaped clamping plate 23, not shown in the figure, and the electromagnetic latch is a commercially available product, and a socket that cooperates with the electromagnetic latch is provided on the rotating disk 2.

[0031] Embodiment 3: This embodiment is basically the same as Embodiment 1, except that the sliding assembly is a hydraulic rod which is arranged on the rotating disk 2 and fixedly connected to the inner arc-shaped clamping plate 24, which is not shown in the figure.

[0032] Example 4: Figure 2 As shown, this embodiment is basically the same as embodiment 1, except that the rotating disk 2 is rotatably connected to the base 1 via a rotating shaft 26 provided on its bottom surface, and a first bevel gear 28 is fixedly sleeved on the rotating shaft 26, and the left ends of the six screw rods 22 are each provided with a second bevel gear 222 for meshing with the first bevel gear 28.

[0033] The working principle of the above-mentioned rotating disk 2 is: when installing the slices, all the slices can be placed on the rotating disk 2, so that the outer sides of all the slices are restricted by the outer arc clamping plates 23, and then the rotating disk 2 is rotated. The rotating disk 2 drives the first bevel gear 28 to rotate through the rotating shaft 26, so that the first bevel gear 28 drives the second bevel gear 222 to rotate, so that the six screw rods 22 rotate synchronously until the six inner arc clamping plates 24 move synchronously to contact the inner walls of the slices.

[0034] Example 5: Figure 3 As shown, this embodiment is basically the same as Embodiment 2, except that the lower end of the rotating shaft 26 passes through the top surface of the base 1 and is fixedly sleeved with a gear 11, a sliding rod 13 is slidably connected to the side wall of the base 1, a toothed plate 12 for slidingly engaging with the gear 11 is provided at the left end of the sliding rod 13, and the right end of the sliding rod 13 passes through the side wall of the base 1 and is provided with a fixing block 14.

[0035] The working principle of the above-mentioned tooth plate 12 is as follows: in the initial state, the tooth plate 12 is meshed with the gear 11, and the rotating disk 2 cannot rotate. When it is necessary to clamp the slices, the fixed block 14 can be pulled to make the fixed block 14 drive the tooth plate 12 to slide through the sliding rod 13, so that the tooth plate 12 is separated from the gear 11, and the rotating disk 2 can rotate at this time.

[0036] Example 6: Figure 4 As shown, this embodiment is basically the same as the embodiment 3, except that the screw rod 22 is rotatably connected to the annular groove provided on the second bevel gear 222, and the second bevel gear 222 is fixedly connected with a transmission sleeve 223, and a toothed disc 224 for sliding engagement with the transmission sleeve 223 for transmission is slidably sleeved on the screw rod 22;

[0037] The screw rod 22 is hollow inside, and a slider 225 is slidably provided inside the screw rod 22. The slider 225 is fixedly connected to the toothed disc 224 through two connecting columns 226 provided on its side wall, and the two connecting columns 226 pass through the corresponding strip grooves provided on the side wall of the screw rod 22.

[0038] A fixing ring 227 is provided inside the screw rod 22, the right end of the slider 225 is connected to the fixing ring 227 by a spring, the left end of the slider 225 is connected to the left end of the screw rod 22 by a first air bag 228, and a second air bag 229 connected to the first air bag 228 by a pipe is fixedly provided at the right end of the screw rod 22, the pipe passes through the slider 225, the fixing ring 227 and the right end of the screw rod 22 in sequence, and the pipe is slidably connected to the slider 225.

[0039] The working principle of the above-mentioned screw rod 22 is as follows: in the initial state, the toothed disc 224 and the transmission sleeve 223 are in a meshing state. When the segments are fixed, the second airbag 229 can be pressed to inflate the first airbag 228 and push the slider 225 to slide. The slider 225 drives the toothed disc 224 to slide and disconnect from the transmission sleeve 223. At this time, the hand wheel 221 can be rotated to allow the screw rod 22 to fine-tune the position of a single inner arc clamp 24 one by one to avoid unstable clamping of some segments.
