DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0018] See also Figure 1-Figure 4 A butt welding device for water conservancy engineering pipelines includes a welding table 100, a fixed clamp seat 200 and a sliding clamp seat 300 driven by an electric push rod are respectively installed on the top of the welding table 100, a rotating plate 400 is rotatably connected inside the welding table 100, a welding gun 500 driven by an electric push rod is installed inside the rotating plate 400, and a clamp plate 600 is slidably connected to the sliding clamp seat 300; The welding table 100 is provided with a clamping assembly 700, which includes a hydraulic chamber 1 701, one end of which is equipped with an oil pump 702, and the other end of which is slidably connected with a connecting rod 703, which is fixedly connected to the clamping plate 600. The oil pipeline is assembled on the oil pump 702, and the oil pump 702 is started, and oil can be injected into the hydraulic chamber 1 701 connected to the oil pump 702, so that the pressure in the hydraulic chamber 1 701 increases, driving the connecting rod 703 slidably connected to the hydraulic chamber 1 701 to move, and the connecting rods 703 on both sides respectively drive the two clamping plates 600 to move toward each other, so as to preliminarily clamp the pipeline.

[0019] The inside of the clamp 600 is fixedly connected with a hydraulic chamber 2 704 that penetrates through it, one end of the hydraulic chamber 2 704 is slidably connected with a force block 705, and the other end of the hydraulic chamber 2 704 is slidably connected with an arc block 706. The side of the clamp 600 is rotatably connected with a torsion spring rod 707, and the outer side of the torsion spring rod 707 is fixedly connected with a friction plate 708. The friction plate 708 is located on the side of the arc block 706 and is in contact with the arc block 706. When the clamping assembly 700 is enabled, the friction plate 708 is in contact with the inner wall of the sliding clamp seat 300. When the initial clamping of the pipeline is completed, the force block 705 located on the clamping plate 600 is squeezed and moves into the hydraulic chamber 2 704, so that the pressure in the hydraulic chamber 2 704 slidably connected to the force block 705 increases, driving the arc block 706 slidably connected to the hydraulic chamber 2 704 to move. Because the torsion spring rod 707 is rotationally connected to the clamping plate 600, and the friction plate 708 is fixedly connected to the torsion spring rod 707, the arc block 706 squeezes the friction plate 708 and drives the friction plate 708 to rotate. The friction plate 708 then rotates to the inner wall of the sliding clamp seat 300 and applies a certain pressure thereto, thereby increasing the friction between the clamping plate 600 and the sliding clamp seat 300. In this way, the overall stability of the device can be improved when clamping the pipeline, making the subsequent docking operation of the device more stable.

[0020] When in use, the oil pipeline is assembled on the oil pump 702, and the oil pump 702 is started, and oil can be injected into the hydraulic chamber 1 701 connected to the oil pump 702, so that the pressure in the hydraulic chamber 1 701 increases, driving the connecting rod 703 slidably connected to the hydraulic chamber 1 701 to move, and the connecting rods 703 on both sides respectively drive the two clamping plates 600 to move towards each other to perform preliminary clamping on the pipeline; when the preliminary clamping of the pipeline is completed, the force block 705 located on the clamping plate 600 is squeezed and moves into the hydraulic chamber 2 704, so that The pressure in the hydraulic chamber 2 704 which is slidably connected to the force-bearing block 705 increases, driving the arc block 706 which is slidably connected to the hydraulic chamber 2 704 to move. Because the torsion spring rod 707 is rotatably connected to the clamp plate 600, and the friction plate 708 is fixedly connected to the torsion spring rod 707, the arc block 706 squeezes the friction plate 708 and drives the friction plate 708 to rotate. The friction plate 708 then rotates to the inner wall of the sliding clamp seat 300 and applies a certain pressure thereto, thereby increasing the friction between the clamp plate 600 and the sliding clamp seat 300. Example

[0021] See also Figure 1-Figure 6 On the basis of the first embodiment, the welding table 100 is provided with an adjustment assembly 800 inside, and the adjustment assembly 800 includes a hydraulic device 1 801 and a hydraulic device 2 802. The hydraulic device 1 801 is located at the side of the hydraulic chamber 2 704 and is connected to the hydraulic chamber 2 704. The hydraulic device 2 802 is located at the bottom of the hydraulic chamber 1 701 and is connected to the hydraulic chamber 1 701. The side of the hydraulic device 1 801 is slidably connected with an arc rod 803. When the pressure in the hydraulic chamber 2 704 increases, the pressure in the hydraulic device 1 801 connected to the hydraulic chamber 2 704 increases accordingly, driving the arc rod 803 slidably connected to the hydraulic device 1 801 to move.

[0022] The internal rotation of the hydraulic device 802 is connected to a torsion spring block 804, and the sides of the torsion spring block 804 are respectively fixedly connected to a force plate 805 and an arc-shaped blocking block 806. When the arc-shaped rod 803 moves, it can squeeze the force plate 805 and drive the force plate 805 to rotate, so as to Figure 6 Observed from a middle angle, the force-bearing plate 805 drives the torsion spring block 804 fixedly connected thereto to rotate ninety degrees clockwise, so that the torsion spring block 804 drives the arc-shaped blocking block 806 fixedly connected thereto to rotate ninety degrees clockwise, thereby converting the originally closed hydraulic device 2 802 into a connected state.

[0023] The side of the hydraulic device 802 is slidably connected to a gear rod 807, the inside of the welding table 100 is rotatably connected to a rotating rod 808, the outer side of the rotating rod 808 is fixedly connected to a gear 809, the gear 809 meshes with the gear rod 807, the outer side of the rotating plate 400 is fixedly connected to an outer gear ring 810, the outer gear ring 810 meshes with the gear 809. When the hydraulic device 802 is converted into a connected state, the oil input into the hydraulic tank 1 701 can be transmitted to the gear rod 807 and drive the gear rod 807 to move, so as to Figure 5 Observed from a medium angle, the gear rod 807 can drive the gear 809 meshing with it to rotate clockwise, so that the gear 809 drives the outer gear ring 810 meshing with it to rotate counterclockwise, and the outer gear ring 810 then drives the rotating plate 400 fixedly connected to it and the welding gun 500 assembled on the rotating plate 400 through the electric push rod to rotate. When it rotates to the specified position, the electric push rod and the welding gun 500 are started, and welding can be performed on various parts of the outer wall of the pipeline. There is no need to rotate the pipeline to weld various parts of the outer wall of the pipeline, which makes the device easier to use.

[0024] When in use, based on the first embodiment, when the pressure in the hydraulic chamber 2 704 increases, the pressure in the hydraulic device 1 801 connected to the hydraulic chamber 2 704 increases accordingly, driving the arc rod 803 slidably connected to the hydraulic device 1 801 to move, so that the arc rod 803 squeezes the force plate 805 and drives the force plate 805 to rotate, so as to Figure 6 From the middle perspective, the force plate 805 drives the torsion spring block 804 fixedly connected thereto to rotate 90 degrees clockwise, so that the torsion spring block 804 drives the arc-shaped blocking block 806 fixedly connected thereto to rotate 90 degrees clockwise, and the originally closed hydraulic device 2 802 is converted into a connected state. At this time, the oil input into the hydraulic tank 1 701 can be transmitted to the gear rod 807 and drive the gear rod 807 to move, so as to Figure 5 Observed from a medium angle, the gear rod 807 can drive the gear 809 meshing with it to rotate clockwise, so that the gear 809 drives the outer gear ring 810 meshing with it to rotate counterclockwise, and the outer gear ring 810 then drives the rotating plate 400 fixedly connected to it and the welding gun 500 assembled on the rotating plate 400 through the electric push rod to rotate. When it rotates to the specified position, the electric push rod and the welding gun 500 are started to weld various parts of the outer wall of the pipeline. Example

[0025] See also Figure 1-Figure 8On the basis of the first and second embodiments, a limiting assembly 900 is provided inside the welding table 100, and the limiting assembly 900 includes a hydraulic device 3 901, and the hydraulic device 3 901 is located at the side of the hydraulic chamber 2 704 and is connected to the hydraulic chamber 2 704. When the pressure in the hydraulic chamber 2 704 increases, the pressure in the hydraulic device 3 901 connected to the hydraulic chamber 2 704 increases accordingly. A ratchet 902 is slidably connected to the side of the hydraulic device 3 901. When the pressure in the hydraulic device 3 901 increases, the ratchet 902 slidably connected to the hydraulic device 3 901 is driven to move. A spring 903 is fixedly connected to the side of the ratchet 902, and a ratchet 904 is fixedly connected to the outer side of the rotating rod 808. When the pawl 902 moves to the side position of the ratchet 904 and engages with the ratchet 904, because the ratchet 904 is fixedly connected to the rotating rod 808, the rotation direction of the gear 809 fixedly connected to the rotating rod 808 can be limited by the pawl 902 and the ratchet 904, so that the gear 809 can only rotate clockwise, thereby improving the stability of the adjustment component 800 when in use.

[0026] During use, on the basis of Example 1 and Example 2, when the pressure in hydraulic chamber 2 704 increases, the pressure in hydraulic device 3 901 connected to hydraulic chamber 2 704 increases accordingly, driving the pawl 902 slidingly connected to hydraulic device 3 901 to move, and the pawl 902 moves to the side position of the ratchet 904 and engages with the ratchet 904. Because the ratchet 904 is fixedly connected to the rotating rod 808, the rotation direction of the gear 809 fixedly connected to the rotating rod 808 can be limited by the pawl 902 and the ratchet 904, so that the gear 809 can only rotate clockwise.
