[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier 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 construction pipeline docking support device includes a base 1, an adjustable docking assembly 2 is fixedly installed on the front and rear parts of the upper end of the base 1, and a quick-fixing pipeline assembly 3 is fixedly installed on the left and right positions of the top of the adjustable docking assembly 2.

[0026] By adjusting the docking assembly 2, the pipes fixed in the two rotating tubes 27 can be brought closer to each other to the docking position, without the need for manual handling and adjustment, which is relatively labor-saving. Secondly, the driving action between the cylinder 210, the two racks 29 and the gear 28 can change the welding position of the two pipes during the docking process, reducing the construction time of the staff and being relatively convenient. The fast-fixing pipe assembly 3 can quickly fix the two pipes to be docked, without the need for manual limiting and without being affected by the two rotating tubes 27. It is highly practical, facilitates the loading and unloading operations of the device, and can speed up the processing process of pipe docking.

[0027] like Figure 2 and Figure 3 As shown, the adjustment docking assembly 2 includes two U-shaped frames 21, the lower ends of the two U-shaped frames 21 are fixedly installed with the front and rear parts of the upper end of the base 1, the inner wall of the rear U-shaped frame 21 is rotatably connected with a reverse double-threaded rod 22 that passes through the left part of the U-shaped frame 21, the left end of the reverse double-threaded rod 22 is fixedly installed with a handwheel 23, the left and right parts of the outer wall of the reverse double-threaded rod 22 are both threadedly connected with movable plates 24, the inner wall of the front U-shaped frame 21 is fixedly installed with a slide rod 25, and the front inner walls of the two movable plates 24 are slidably connected with the left and right parts of the outer wall of the slide rod 25.

[0028] When two pipes need to be docked, the hand wheel 23 is turned, and the hand wheel 23 drives the reverse double-threaded rod 22 to rotate. The two movable plates 24 are threadedly connected with the reverse double-threaded rod 22 and approach each other until the pipes in the two rotating tubes 27 approach each other to the docking position, wherein the sliding rod 25 has a limiting effect on the movement of the two movable plates 24.

[0029] like Figure 2 、 Figure 3 and Figure 4As shown, mounting brackets 26 are fixedly mounted on the left and right parts of the upper ends of the two movable plates 24, and rotating tubes 27 are rotatably connected to the inner walls of the four adjacent mounting brackets 26. Gears 28 are fixedly sleeved on the middle parts of the outer walls of the two rotating tubes 27. Racks 29 are slidably connected to the bottoms of the two mounting brackets 26 in the middle that are away from each other. The outer surfaces of the two gears 28 are engaged with the upper ends of the two racks 29. A cylinder 210 is fixedly mounted on the left bottom of the second mounting bracket 26 from left to right on the left, and the output end of the cylinder 210 is fixedly connected to the rear part of the lower end of the rack 29 on the left.

[0030] When the welding position of the two pipes needs to be changed, the output end of the cylinder 210 can drive the rack 29 on the left to move, and the two racks 29 move synchronously through the connection between the accommodating sleeve 211 and the connecting plate 212. The two gears 28 drive the two rotating tubes 27 to rotate synchronously by engaging with the two racks 29, so that the two pipes fixed in the two rotating tubes 27 can be rotated to different positions.

[0031] like Figure 4 As shown, a housing sleeve 211 is fixedly installed on the right front portion of the left rack 29 , and a connecting plate 212 is fixedly installed on the left front portion of the right rack 29 . The front and rear sides of the connecting plate 212 are slidably connected to the inner wall of the housing sleeve 211 .

[0032] When the two movable plates 24 move relative to each other, the connecting plate 212 slides in the accommodating sleeve 211 . The cooperation between the accommodating sleeve 211 and the connecting plate 212 not only connects the two racks 29 but also enables the two racks 29 to move synchronously.

[0033] like Figure 5 and Figure 6 As shown, the quick-fix pipe assembly 3 includes two positioning rings 31, the outer walls of the two positioning rings 31 are fixedly connected to the middle of the inner walls of the two rotating tubes 27, the front positions of the tops of the opposite sides of the two positioning rings 31 are rotatably connected with turntables 32, the opposite sides of the two turntables 32 are fixedly installed with micro motors 33, the output ends of the two micro motors 33 are fixedly connected with screws 34, the middle parts of the two positioning rings 31 on each other's sides are rotatably connected with inner rings 35, the tops of the two inner rings 35 away from each other are fixedly installed with moving blocks 36, and the inner walls of the two moving blocks 36 are threadedly connected to the outer walls of the two screws 34.

[0034] When it is necessary to fix the two pipes in the two rotating tubes 27 respectively, the two micro motors 33 are started. The output ends of the two micro motors 33 can drive the corresponding screws 34 to rotate. The two moving blocks 36 drive the corresponding inner rings 35 to rotate by being threadedly connected with the two screws 34. The rotation of the two inner rings 35 themselves limits the movement of the two moving blocks 36.

[0035] like Figure 6 As shown, the outer walls of the two inner rings 35 are provided with three arc-shaped movable grooves 37 arranged in a ring form, the inner walls of the six arc-shaped movable grooves 37 are rotatably connected to the limiting sleeves 38, and the edges of the opposite sides of the two positioning rings 31 are rotatably connected to three fixing rods 39, and the front and rear sides of the six fixing rods 39 are slidably connected to the inner walls of the six limiting sleeves 38.

[0036] When the two inner rings 35 rotate, the six fixing rods 39 rotate around the two positioning rings 31 due to the limiting effect of the corresponding limiting sleeves 38. At the same time, the six fixing rods 39 extend or retract in the corresponding limiting sleeves 38, thereby achieving the clamping and fixation of pipes of different sizes.

[0037] like Figure 6 As shown, one end of each of the three fixing rods 39 close to the axis of the two inner rings 35 is rotatably connected to a positioning wheel 310, and the outer surfaces of the six positioning wheels 310 are provided with a rubber layer.

[0038] Each fixing rod 39 clamps the pipeline through the positioning wheel 310, and the rubber layer on the surface of the positioning wheel 310 can protect the pipeline from damage.

[0039] The working principle of the present invention is as follows: first, two pipes to be connected are inserted into the two rotating tubes 27, and the ends of the two pipes close to each other are slightly extended from the two rotating tubes 27, and the two micro motors 33 are started. The output ends of the two micro motors 33 can drive the corresponding screws 34 to rotate, and the two moving blocks 36 drive the corresponding inner rings 35 to rotate by being threadedly connected with the two screws 34. When the two inner rings 35 rotate, the six fixing rods 39 rotate around the two positioning rings 31 due to the limiting effect of the corresponding limiting sleeves 38. At the same time, the six fixing rods 39 extend or retract in the corresponding limiting sleeves 38, thereby realizing the clamping and fixation of pipes of different sizes.

[0040] Subsequently, the hand wheel 23 is turned, and the hand wheel 23 drives the reverse double-threaded rod 22 to rotate. The two movable plates 24 are threadedly connected to the reverse double-threaded rod 22 and approach each other until the pipes in the two rotating tubes 27 approach each other to the docking position. The staff welds the pipe docking position. When the welding position of the two pipes needs to be changed, the output end of the cylinder 210 can drive the rack 29 on the left to move. The two racks 29 move synchronously through the connection between the accommodating sleeve 211 and the connecting plate 212. The two gears 28 drive the two rotating tubes 27 to rotate synchronously by meshing with the two racks 29, so that the two fixed pipes in the two rotating tubes 27 can be rotated to different positions, which is convenient for the staff to carry out construction and is more convenient.
