DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 In this embodiment, a valve body fixing assembly for a blowout preventer control device includes a valve body 1, a fixing box 2 is provided on the lower side of the valve body 1, fixing mechanisms 3 for fixing the valve body 1 are provided on both left and right ends between the top wall and the inner bottom wall of the fixing box 2, and clamping mechanisms 4 for clamping the valve body 1 are provided on both left and right sides of the bottom of the valve body 1.

[0022] See also Figure 2In order to fix the valve body 1, the fixing mechanism 3 in this embodiment includes connecting plates 301 fixed at the left and right ends between the inner top wall and the inner bottom wall of the fixing box 2. A double-axis motor 302 is fixed at the middle of the inner top wall of the fixing box 2. The left and right ends of the double-axis motor 302 are rotatably connected to the side opposite to the two connecting plates 301 through bearings with a first threaded rod 303. The bottom of the opposite side of the two connecting plates 301 is rotatably connected to a bidirectional screw 304 through a bearing. The two first threaded rods 303 are threadedly connected to the side opposite to the left and right ends of the bidirectional screw 304 with the same movable plate 305. The double-axis motor 302 The output shaft rotates, thereby driving the two first threaded rods 303 to rotate. At this time, the bidirectional screw 304 can be rotated by a belt. The rotation of the first threaded rod 303 and the bidirectional screw 304 can move the movable plate 305. The two movable plates 305 are fixed with plug posts 306 on the opposite sides. Through holes 307 are provided at both ends of the upper surface of the fixed box 2. The inner cavity of the through hole 307 is provided with a limit plate 308. The left side of the limit plate 308 is provided with a socket 309. The movement of the movable plate 305 can drive the plug post 306 to move until the plug post 306 enters the inner cavity of the limit ring through the socket 309, so that the two limit plates 308 can be limited.

[0023] In this embodiment, a fixing hole matching the size of the plug column 306 is opened on the left side of the connecting plate 301, and the bidirectional screw 304 is connected to the first threaded rod 303 at the left end by a belt drive. Slide bars are fixed on the opposite sides of the top wall and the bottom wall of the fixed box 2, and the upper and lower ends of the two movable plates 305 make horizontal linear motion in the inner cavity of the slide bar, which can limit the movement of the movable plate 305.

[0024] Among them, the outer diameter of the column 306 is compatible with the inner diameter of the through hole 307, the size of the inner cavity of the hole 309 is compatible with the size of the limit plate 308, and the limiting rings are fixed on the opposite sides of the left and right side walls of the inner cavity of the fixed box 2. The shape of the limiting ring is hollow inside and the side of the limiting ring facing the column 306 is a missing cylinder. The inner cavity of the limiting ring is fixed with a limiting column, the outer diameter of the column 306 is compatible with the inner diameter of the limiting ring, and the side of the column 306 facing the limiting ring is provided with a limiting groove compatible with the limiting column.

[0025] It should be noted that the two output shafts of the dual-axis motor 302 rotate in the same direction, and the threads on the outer surfaces of the two first threaded rods 303 are in opposite structures.

[0026] See also Figure 3-4In order to fix the position of the valve body 1, the clamping mechanism 4 in this embodiment includes vertical plates 401 arranged on the left and right sides of the bottom of the valve body 1, and one side of the vertical plate 401 is threadedly connected to a second threaded rod 402 with one end penetrating and extending away from the vertical plate 401. The valve body 1 is placed on the upper surface of the fixing box 2 so that the valve body 1 is on the opposite side of the two clamping mechanisms 4, and then the second threaded rod 402 is rotated. The rotation of the second threaded rod 402 causes it to move toward the side close to the valve body 1. The opposite sides of the two second threaded rods 402 are rotatably connected with clamping plates 403 through bearings. The movement of the second threaded rod 402 drives the clamping plates 403 to move until the clamping plates 403 on both sides clamp and fix the bottom of the valve body 1.

[0027] Among them, the lower surface of the vertical plate 401 is fixed to the upper surface of the limit plate 308, and rubber plates are fixed on the opposite sides of the two clamping plates 403, which can increase the friction between the clamping plates 403 and the valve body 1, and telescopic rods are fixed on the upper and lower ends of the opposite sides of the vertical plate 401 and the clamping plates 403. When the clamping plate 403 moves, it will drive the two telescopic rods to extend, thereby limiting the movement of the clamping plate 403.

[0028] It can be understood that, by providing the fixing mechanism 3 and the clamping mechanism 4, the valve body 1 can be fixed to prevent it from shaking and causing the pipeline to rupture, and it is convenient for the staff to install and disassemble without the help of tools.

[0029] The working principle of the above embodiment is:

[0030] (1) When fixing the valve body 1, first weld the fixing box 2 to the outer surface of the oil tank, then put the two limit plates 308 into the fixing box 2 through the through holes 307 respectively, and then start the dual-axis motor 302. The output shaft of the dual-axis motor 302 rotates, thereby driving the two first threaded rods 303 to rotate. At this time, the bidirectional screw rod 304 can be rotated by the belt. The rotation of the first threaded rod 303 and the bidirectional screw rod 304 can move the movable plate 305. At this time, the upper and lower ends of the two movable plates 305 move in the inner cavity of the slide bar, which can limit the movement of the movable plate 305. The movement of the movable plate 305 can drive the plug column 306 to move until the plug column 306 enters the inner cavity of the limit ring through the plug hole 309, so that the two limit plates 308 can be limited.

[0031] (2) The valve body 1 is then placed on the upper surface of the fixing box 2 so that the valve body 1 is on the opposite side of the two clamping mechanisms 4, and then the second threaded rod 402 is rotated. The rotation of the second threaded rod 402 causes it to move toward the side close to the valve body 1. The movement of the second threaded rod 402 drives the clamping plate 403 to move until the clamping plates 403 on both sides clamp and fix the bottom of the valve body 1. When the clamping plate 403 moves, it drives the two telescopic rods to extend, thereby limiting the movement of the clamping plate 403.
