DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 and Figure 2 As shown, a steel pipe flange alignment device includes a base 1, fixed limit assemblies 2 are fixedly installed on the left and right parts of the upper end of the base 1, steel pipes 4 with welded flanges are overlapped on the left and right positions of the top of the fixed limit assembly 2, and an adjustable alignment assembly 3 is fixedly installed at the front and rear positions of the middle part of the upper end of the base 1.

[0026] The two steel pipes 4 can be fixed on the four storage seats 21 by fixing the limiting assembly 2, so that the positions of the two flanges can be determined. When the two arc limiting plates 33 are aligned, the axis positions of the two arc limiting plates 33 can always be in the same straight line with the axis positions of the two steel pipes 4, so as to improve the accuracy of the alignment of the two flanges. The two flanges can be quickly fitted and aligned by adjusting the alignment assembly 3. The structure is simple, and only two insertion rods 36 are needed to successfully align the two flanges, which can ensure that the two steel pipes 4 are correctly aligned and connected, thereby improving the working efficiency of the equipment.

[0027] like Figure 2 and Figure 3 As shown, the fixed limiting assembly 2 includes four storage seats 21, the lower ends of the four adjacent storage seats 21 are fixedly installed on the left and right parts of the upper end of the base 1, the upper ends of the four storage seats 21 are all provided with arc grooves 22, and a designated rod 23 is fixedly installed at the front position of the middle part of the upper end of the base 1.

[0028] The two steel pipes 4 are respectively passed through the two mounting frames 24 by the lifting mechanism and placed on the four storage seats 21, and the four storage seats 21 are provided with arc grooves 22 to ensure the fixing stability of the two steel pipes 4. The staff can roughly determine the horizontal position of the two flanges according to the position of the designated rod 23, as long as the two arc-shaped limit plates 33 can contact the outer walls of the two flanges, and no excessive adjustment is required.

[0029] like Figure 3 As shown, mounting brackets 24 are fixedly installed at the front and rear positions of the left and right parts of the upper end of the base 1, and threaded rods 25 that pass through the tops of the two mounting brackets 24 are threadedly connected to the middle parts of the upper ends of the two mounting brackets 24, and hand wheels are fixedly installed on the upper ends of the two threaded rods 25. The lower ends of the two threaded rods 25 are rotatably connected to arc-shaped fixing plates 26, and the lower ends of the two arc-shaped fixing plates 26 overlap the tops of the outer walls of the two steel pipes 4.

[0030] By rotating the two hand wheels, the two hand wheels can drive the two threaded rods 25 to rotate, and the two threaded rods 25 can move up and down through the threaded connection with the two mounting frames 24. Both of them can drive the two arc-shaped fixing plates 26 to move up and down through the two limit rods 27, so that the two arc-shaped fixing plates 26 can fix steel pipes 4 of different sizes.

[0031] like Figure 3 As shown, the front and rear parts of the upper ends of the two mounting frames 24 are slidably connected to the limit rods 27, and the lower ends of the four adjacent limit rods 27 are fixedly connected to the front and rear parts of the upper ends of the two arc-shaped fixing plates 26.

[0032] The four adjacent limiting rods 27 have a limiting effect on the movement of the two arc-shaped fixing plates 26 .

[0033] like Figure 2 , Figure 4 and Figure 5 As shown, the eye adjustment component 3 includes a fixing frame 31, the front and rear parts of the lower end of the fixing frame 31 are fixedly connected to the front and rear positions of the middle part of the upper end of the base 1, and electric push rods 32 are fixedly installed on the left and right parts of the upper end of the fixing frame 31. The output ends of the two electric push rods 32 pass through the top of the fixing frame 31 and are fixedly installed with arc-shaped limit plates 33.

[0034] The output ends of the two electric push rods 32 can drive the two arc-shaped limit plates 33 to contact flanges of different sizes. The two electric push rods 32 should respectively drive the corresponding arc-shaped limit plates 33 to move to the same height.

[0035] like Figure 4 As shown, connecting blocks 34 are fixedly installed on the front and rear parts of the upper ends of the two arc-shaped limit plates 33, and eye holes 35 are opened on the right sides of the four connecting blocks 34. The inner walls of the two eye holes 35 on the right are slidably connected with plug rods 36, and the right ends of the two plug rods 36 are fixedly installed with mounting circular plates 37. The left parts of the outer walls of the two plug rods 36 are slidably connected to the inner walls of the two eye holes 35 on the left, and the right parts of the outer walls of the two plug rods 36 are movably sleeved with springs 38. The left ends of the two springs 38 are fixedly connected to the right sides of the two connecting blocks 34 on the right, and the right ends of the two springs 38 are fixedly connected to the left sides of the two mounting circular plates 37.

[0036] By pulling the two insertion rods 36, the two insertion rods 36 slide in the four connection blocks 34. When the two insertion rods 36 are successfully inserted into the four eye holes 35, it can be determined that the two flanges are successfully aligned. When the insertion rods 36 move, the corresponding springs 38 are acted upon by force and accumulate elastic potential energy or release elastic potential energy. The main function of the springs 38 is to drive the insertion rods 36 to reset and ensure that the two insertion rods 36 are always located in the two eye holes 35.

[0037] like Figure 5 As shown, a connecting frame 39 is fixedly installed at the front and rear positions of the upper right part of the fixed frame 31, and an adjusting screw 310 is threadedly connected to the upper end of the front connecting frame 39, and a baffle 311 is rotatably connected to the lower end of the adjusting screw 310. The front and rear positions of the bottom right side of the baffle 311 abut against the left top of the two mounting circular plates 37.

[0038] By rotating the adjusting screw 310, the adjusting screw 310 moves up and down by being threadedly connected with the front connecting frame 39, and the adjusting screw 310 can drive the baffle 311 to move up and down by cooperating with the sliding rod 312. When the baffle 311 abuts against the two mounting circular plates 37, the two springs 38 are subjected to a tensile force at this time, and the two plug rods 36 are away from the two connecting blocks 34 located on the left, so as to prevent the two arc-shaped limit plates 33 from being disturbed by the positions of the two plug rods 36 when they move separately. When the baffle 311 moves upward, the two mounting circular plates 37 can contact and be restricted, and the elastic restoring force of the two springs 38 can drive the two plug rods 36 to move to the left. When the two plug rods 36 are successfully inserted into the four eye holes 35, the two flanges are successfully aligned.

[0039] like Figure 5 As shown, the upper end of the rear connecting frame 39 is slidably connected to a slide bar 312 that passes through the top of the rear connecting frame 39 , and the lower end of the slide bar 312 is fixedly connected to the rear of the upper end of the baffle 311 .

[0040] The sliding rod 312 limits the movement of the baffle 311 .

[0041] The working principle of the utility model is as follows: the staff use the lifting mechanism to pass the two steel pipes 4 through the two mounting frames 24 respectively, so that the two steel pipes 4 are respectively located on the corresponding storage seats. During this period, the staff can judge the horizontal position of the two flanges according to the designation of the designated rod 23, and it is only necessary to ensure that the two arc-shaped limit plates 33 can contact the outer walls of the two flanges.

[0042] By rotating the two hand wheels, the two threaded rods 25 are threadedly connected with the two mounting brackets 24 to drive the arc-shaped fixing plates 26 to move up and down, so that the two arc-shaped fixing plates 26 can quickly fix the two steel pipes 4.

[0043] Then, the electric push rod 32 on the right is started, and the output end of the electric push rod 32 on the right drives the arc-shaped limit plate 33 on the right to move downward. Before the arc-shaped limit plate 33 on the right moves, the baffle 311 is located on the left side of the two mounting circular plates 37 and limits the two insertion rods 36 from moving left. The output end of the electric push rod 32 on the right drives the two insertion rods 36 to move to the specified position. At the same time, the two mounting circular plates 37 are separated from the limiting effect of the baffle 311, and the elastic restoring force of the two springs 38 drives the corresponding insertion rods 36 to reset.

[0044] In order not to affect the movement of the arc-shaped limit plate 33 on the left, pull the two mounting circular plates 37, and the two mounting circular plates 37 drive the two plug rods 36 to move to the right. At this time, the two springs 38 are stretched and accumulate elastic potential energy. Then, rotate the adjusting screw 310. The adjusting screw 310 drives the baffle 311 to move downward by being threadedly connected with the corresponding connecting frame 39. When the baffle 311 moves to a suitable position, release the two mounting circular plates 37. The two springs 38 release the elastic potential energy, so that the two mounting circular plates 37 are stuck by the right bottom of the baffle 311. Then, move the electric push rod 32 on the left so that the arc-shaped limit plate 33 on the left contacts with the flange on the left. The two arc-shaped limit plates 33 need to move the same distance.

[0045] Subsequently, the adjusting screw 310 is rotated, the baffle 311 moves upward, the two mounting circular plates 37 are released, and the elastic potential energy of the corresponding spring 38 drives the insertion rod 36 to move leftward. If the two insertion rods 36 are inserted into the four eye holes 35, the two flanges are successfully aligned.

[0046] After the two steel pipes 4 are connected through the two flanges, the two electric push rods 32 are started at the same time. The output ends of the two electric push rods 32 drive the two arc-shaped limit plates 33 to move upward to the appropriate position, pull the two mounting circular plates 37, and then rotate the adjusting screw 310 to drive the baffle 311 to clamp the two mounting circular plates 37 again, so as to facilitate the subsequent pipeline flange alignment work.
