In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0018] See Figure 1 A steel pipe welding tool for an umbilical cable shown in a preferred embodiment of the present application includes a supporting movable plate 1, a fixed frame 2, a guide mechanism 3, a first positioning mechanism 4 and a second positioning mechanism 5. The fixed frame 2 can be tilted on the supporting movable plate 1. The two guide mechanisms 3 are respectively arranged on both sides of the fixed frame 2, and each guide mechanism 3 includes a plurality of U-shaped wheels 31. The first positioning mechanism 4 is arranged between the two guide mechanisms 3 and can move back and forth in the horizontal direction, and is used to clamp and position the steel pipe vertically. The second positioning mechanism 5 is arranged between the first positioning mechanism 4 and the guide mechanism 3, and is used to clamp and position the steel pipe horizontally. The clamping channel formed by the first positioning mechanism 4 and the second positioning mechanism 5 is on the same axis.
[0019] According to the solution of the embodiment of the present invention, a tiltable fixed frame 2 is set on the supporting movable plate 1, and an adjustable guiding mechanism 3 and a first positioning mechanism 4 and a second positioning mechanism 5 on the same axis are configured on both sides of the fixed frame 2 to form a coaxial clamping channel, thereby achieving precise guiding, coaxial clamping and overall tilt adaptation of the steel pipe at the same time, which not only ensures high-precision alignment of the steel pipes at both ends in the horizontal and vertical directions, but also allows the overall tooling to be tilted according to welding needs, significantly improving the weld alignment accuracy and clamping stability, thereby reducing defects such as misalignment and air holes and improving the welding qualification rate and production line adaptability.
[0020] The following is a detailed description with specific embodiments: See Figure 1 The steel pipe welding tool on the umbilical cable also includes a tilting mechanism 6, which includes a movable slide 61, a lifting link 62 and a first screw 63. The movable slide 61 is arranged on the supporting movable plate 1. One end of the lifting link 62 is slidably arranged on the movable slide 61, and a connecting member 64 is provided between one end of the lifting link 62 and the movable slide 61. The other end of the lifting link 62 is hinged to one end of the bottom of the fixed frame 2, and the other end of the bottom of the fixed frame 2 is hinged to the end of the supporting movable plate 1. The first screw 63 is arranged on the supporting movable plate 1, and is used to drive the connecting member 64 to move back and forth in the horizontal direction. The reciprocating feeding of the lifting link 62 on the movable slide 61 is controlled by the first screw 63 to realize the lifting and lowering of one end of the fixed frame 2 and the overall tilting, and can be used in conjunction with an angle ruler to realize angle control and repeated positioning, so as to facilitate precise adjustment of the welding angle on site.
[0021] See Figure 1 The steel pipe welding tool on the umbilical cable also includes a moving mechanism 7, which includes a guide rod 71, a moving slider 72, a second screw 73 and a first bracket 74. The guide rod 71 is arranged on the fixed frame 2, and the moving slider 72 is slidably arranged on the guide rod 71. The second screw 73 is arranged on the fixed frame 2, and is used to drive the moving slider 72 to move back and forth in the horizontal direction. The first bracket 74 is arranged on the moving slider 72, and the first positioning mechanism 4 is arranged on the first bracket 74. With this arrangement, the fine lateral movement and rapid positioning of the first positioning mechanism 4 can be achieved, and the front and rear positions of the clamping point can be accurately adjusted by the second screw 73 to meet the requirements of different connection positions and reserved weld space.
[0022] Specifically, see Figure 1The guide mechanism 3 includes a fixed plate 32, a support vertical plate 33 and a rubber-coated roller 34. The fixed plate 32 is set on the fixed frame 2, and a plurality of U-shaped wheels 31 are adjustably set on the fixed plate 32. The support vertical plate 33 is set on the side of the fixed plate 32 away from the first positioning mechanism 4. Two rubber-coated rollers 34 are adjustably set on the support vertical plate 33, and are used to cooperate with the U-shaped wheels 31 to guide the steel pipe. The guide mechanism 3 is refined into a fixed plate 32 fixed on the fixed frame 2, a plurality of U-shaped wheels 31 adjustably mounted on the fixed plate 32, and a support vertical plate 33 set on the far side of the fixed plate 32 and two rubber-coated rollers 34 adjustable thereon. The cooperation between the U-shaped wheel 31 and the rubber-coated roller 34 realizes multi-point guiding and center positioning of the steel pipe, and the adjustability of the U-shaped wheel 31 and the rubber-coated roller 34 enables it to adapt to steel pipes of different outer diameters and curvatures, ensuring smooth pipe entry and reducing indentations or displacement on the pipe surface. Specifically, sliding grooves are provided on the fixed plate 32 and the supporting vertical plate 33, and the U-shaped wheel 31 and the rubber-coated roller 34 can be adjusted through the sliding grooves.
[0023] See Figure 1 and Figure 2 The first positioning assembly includes a lower clamping block 41, a first support frame 42, an upper clamping block 43, and a first push rod 44. The lower clamping block 41 is arranged at the top of the first bracket 74, and the first support frame 42 is arranged at the top of the first bracket 74. The upper clamping block 43 is arranged on the first support frame 42 and can move vertically. A guide column 45 is provided between the upper clamping block 43 and the top of the first support frame 42. The upper clamping block 43 and the lower clamping block 41 cooperate to form a first clamping channel. The first push rod 44 is threadedly connected to the top of the first support frame 42. One end of the first push rod 44 presses against the upper clamping block 43, and the other end of the first push rod 44 extends upward through the top of the first support frame 42. The other end of the first push rod 44 is provided with a first handle wheel 46. This arrangement can achieve reliable vertical clamping and height adjustment. The threaded cooperation between the handle wheel and the push rod facilitates manual force application, fine-tuning of the clamping force, and quick locking, ensuring that the steel pipe is stable and does not shift in the vertical direction.
[0024] See Figure 1 and Figure 2 The second positioning assembly includes a support platform 51, an adjustment rail 52, a second bracket 53, a left pressure block 54, a right pressure block 55, and a second stopper. The support platform 51 is positioned on the side of the fixed frame 2. The adjustment rail 52 is horizontally positioned on the support platform 51 and perpendicular to the axis of the second lead screw 73. The second bracket 53 is mounted on the adjustment rail 52 and can be moved and adjusted along the adjustment rail 52. The left pressure block 54 is fixedly mounted on one side of the second bracket 53. The right pressure block 55 is positioned on the other side of the second bracket 53. The left and right pressure blocks 54 and 55 cooperate to form a second clamping channel.
[0025] Further, see Figure 1, a horizontal positioning foot pad 8 is provided at the bottom of the supporting movable plate 1. Universal wheels 9 are provided at the four corners of the supporting movable plate 1.
[0026] During on-site welding, first move the welding tool to the welding position through the universal wheel 9 and lower the horizontal positioning foot pad 8 to fix it. After the bent steel pipe to be connected is straightened, put it into the guide mechanism 3 on the corresponding side, adjust the U-shaped wheel 31 on the fixing plate 32 and the rubber-coated roller 34 on the supporting vertical plate 33 to make the steel pipe fit the guide channel; put another section of steel pipe into the guide mechanism 3 on the other side as needed, use the left and right clamping blocks 55 of the second positioning assembly and the second push rod to roughly adjust the horizontal position, and then use the upper and lower clamping blocks 41 of the first positioning assembly and the first push rod 44 to complete the vertical clamping; Fine adjustment is achieved forward and backward through the moving mechanism 7 and the first bracket 74 to make the two steel pipe ports coaxial and leave enough space for welding; if inclined welding is required, the first screw 63 drives the connecting piece 64 to drive the lifting link 62 to move on the movable slide rail 61, so that one end of the fixed frame 2 is raised and lowered and the required inclination angle is read and locked by the angle ruler; after the tooling is positioned and clamped, the welding operation is carried out after checking the matching and protection. After the welding is completed, the support rod is loosened, the clamping block is released and the connected steel pipe is removed. If necessary, the clamping block suitable for different outer diameters is replaced to continue the next connection.
[0027] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0028] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
