Description
Technical Field
[0001] The utility model relates to the technical field of heating pipeline docking, in particular to a heating pipeline docking device. Background Technique
[0002] A heating pipeline is a pipeline system used to transport hot water or steam to provide heat energy. The heating pipeline needs to be installed underground or above ground. Since the heating pipeline network is large, several heating pipelines need to be docked and connected. Adjacent two heating pipelines are usually butt-welded after being butted by a pipe aligner.
[0003] The structure of the existing pipe aligner generally includes two semi-pipe aligners that are buckled up and down. A single semi-pipe aligner includes two semi-circular rings and a connecting plate connecting the two semi-circular rings. The two semi-circular rings located below are arranged corresponding to the two semi-circular rings above, forming a space for accommodating two adjacent pipes. The two ends of the two semi-pipe aligners are tightened simultaneously by bolts, playing a role in clamping the two butt-welded pipes, which is convenient for welding.
[0004] Since the two same-diameter heating pipelines to be butted are relatively long, it is difficult for the existing technology to align the ports of the two heating pipelines well only through two semi-pipe aligners, and only simple clamping can be carried out; and after the ends of the two heating pipelines are clamped, fine adjustment cannot be carried out according to the gap between the two ports. If the gap between the ports of the two heating pipelines is quite different, during water supply, there may be a phenomenon of large vibration at the connection of the two heating pipelines, affecting its service life. Content of the Utility Model
[0005] In order to solve the technical problems existing in the above background technique, the utility model provides a heating pipeline docking device.
[0006] The technical solution of the utility model is as follows:
[0007] A heating pipeline docking device includes two symmetrically arranged and bucklable "V"-shaped docking plates. The length direction of the "V"-shaped docking plate is arranged along the length direction of the heating pipeline. The joints of the two "V"-shaped docking plates are both connected by double-headed screws, and the two "V"-shaped docking plates can move synchronously towards or away from each other;
[0008] At least one welding opening is provided on the "V"-shaped docking plate. At least two adjusting members are provided on the welding opening. The two adjusting members are arranged along the length direction of the "V"-shaped docking plate and correspond to the two butted heating pipelines respectively. The adjusting member includes an adjusting rod that can be tightened against the outer wall of the heating pipeline.
[0009] The two "V"-shaped butt joint plates are arranged to be snapped together and can be snapped together at the connection of two heating pipes that need to be butt-welded. The two "V"-shaped butt joint plates are connected by stud bolts. By rotating the stud bolts, the two "V"-shaped butt joint plates can be synchronously driven to move toward or away from each other, thereby clamping or disengaging the two heating pipes. When the two "V"-shaped butt joint plates are clamped, the gap between the two heating pipes is adjusted to a suitable position by adjusting a plurality of adjustment rods in coordination, so that the two heating pipes are kept coaxial as much as possible. After clamping, the ports of the two heating pipes are welded, thereby reducing the phenomenon that the connection of the two heating pipes cannot be well aligned, resulting in vibration of the heating pipes.
[0010] To ensure that the two "V"-shaped docking plates do not misalign during movement, guide rods are provided at both ends of one of the "V"-shaped docking plates, and guide holes adapted to the guide rods are provided at both ends of the other "V"-shaped docking plate, and the axis of the guide rod is parallel to the axis of the double-headed screw.
[0011] The structure of the above-mentioned adjusting member is that the adjusting member also includes a supporting rod arranged in the welding opening, and the adjusting rod vertically passes through the supporting rod and is threadedly connected to the supporting rod.
[0012] In order to facilitate the adjustment rod to tighten the corresponding heating pipe and fine-tune the port position, the adjustment rod is located on the inner side of the "V"-shaped docking plate and is hinged with an arc plate at one end. The curvature of the arc plate is adapted to the heating pipe, which can increase the contact area with the heating pipe and better tighten the heating pipe. The adjustment rod will not have a small contact point or slipping.
[0013] The specific structure of the above-mentioned "V"-shaped docking plate is that the "V"-shaped docking plate includes a first docking plate and a second docking plate that are integrally formed and vertically connected, and welding openings with adjustment parts are provided on the first docking plate and the second docking plate. By setting two welding openings on a "V"-shaped docking plate, it is convenient to pre-weld the two heating pipes after fine-tuning and aligning them, thereby avoiding misalignment or repeated position adjustment.
[0014] In order to facilitate the adjustment of the gap between the two heating pipes to the same, a leveling rod is slidably connected to the "V"-shaped butt joint plate, and the sliding direction is the length direction of the parallel double-headed screw. A clamp is provided at one end of the leveling rod passing through the "V"-shaped butt joint plate. The clamp can extend into the gap between the two heating pipes. The width of the clamp does not affect the welding of the two heating pipes. After the two heating pipes are pre-welded at several welding points, the clamp can be pulled out.
[0015] Regarding the thickness of the clip, the thickness of the clip is 0.2-2㎜, which can meet the welding requirements of small and medium-sized heating pipes and is also convenient for removing the clip.
[0016] Before the fine adjustment of the two "V"-shaped docking plates, the clamping piece can be first set between the ports of the two heating pipes. A tension spring is sleeved on the leveling rod, and the tension spring is located on the "V"-shaped docking plate. The tension spring can prevent the clamping piece from disengaging from the gap between the two heating pipes when the two "V"-shaped docking plates clamp the heating pipes.
[0017] The beneficial effects of the present utility model are as follows:
[0018] The two "V"-shaped docking plates can be buckled up and down or left and right at the connection of the two heating pipes to be welded, and the clamping of the two "V"-shaped docking plates is synchronously adjusted through the double-headed screws on both sides, and the two heating pipes inside the two "V"-shaped docking plates are clamped;
[0019] Then, the adjusting rods on the welding opening are adjusted. There are four to eight adjusting rods, which are respectively located at different positions at the connection of the two heating pipes. The corresponding heating pipes are finely adjusted through the arc-shaped plates respectively, so that the gaps between the two heating pipes are as consistent as possible, and the phenomenon that there is a large vibration at the connection of the two heating pipes after welding is avoided;
[0020] Manually adjusting multiple adjusting rods has a large error. For this reason, thinner clamping pieces that can be inserted into the gaps between the two "V"-shaped docking plates are respectively arranged on the two "V"-shaped docking plates. The symmetrically arranged clamping pieces can facilitate the quick alignment of the two heating pipes, make the gaps consistent, tighten the adjusting rods and the double-headed screws, and then weld several welding points on the two heating pipes in advance to achieve pre-connection, and avoid the phenomenon that the two heating pipes are misaligned or need to be repeatedly aligned; then the clamping pieces are drawn out, several welding points are welded again, and the two "V"-shaped docking plates are disassembled, and the two heating pipes are welded and connected.

Detailed implementation mode
[0028] Refer to Figure 1 、 Figure 2 and Figure 3 As shown in , and , a heating pipeline docking device includes two symmetrically arranged "V"-shaped docking plates 1 that can be buckled. The length direction of the "V"-shaped docking plate 1 is arranged along the length direction of the heating pipeline 10. The joints of the two "V"-shaped docking plates 1 are all connected by double-headed screws 2, and the two "V"-shaped docking plates 1 can move synchronously towards or away from each other.
[0029] Refer to Figure 1 and Figure 4 As shown in , and , specifically, the structure of the above-mentioned "V"-shaped docking plate 1 is that the "V"-shaped docking plate 1 includes a first docking plate 11 and a second docking plate 12 that are integrally formed and vertically connected. Welding openings 13 with adjusting parts are provided on both the first docking plate 11 and the second docking plate 12. At least two adjusting parts are provided on the welding opening 13. The two adjusting parts are arranged along the length direction of the "V"-shaped docking plate 1 and correspond to the two butt-jointed heating pipelines 10 respectively.
[0030] The adjusting part includes a support rod 5 arranged in the welding opening 13 and an adjusting rod 3 that passes through the support rod 5 and can be tightened against the outer wall of the heating pipeline 10. The adjusting rod 3 vertically passes through the support rod 5 and is threadedly connected to it. By providing two welding openings 13 on one "V"-shaped docking plate 1, it is convenient to perform pre-welding after the two heating pipelines 10 are finely adjusted and aligned, avoiding the phenomenon of dislocation or repeated position adjustment. A total of eight adjusting rods 3 are provided in this embodiment, which can cooperate with the "V"-shaped docking plate 1 to finely adjust the two heating pipelines 10 in multiple directions.
[0031] In this embodiment, to ensure that the two "V"-shaped docking plates 1 do not get dislocated during movement, guide rods 6 are provided at both ends of one "V"-shaped docking plate 1, and guide holes adapted to the guide rods 6 are provided at both ends of the other "V"-shaped docking plate 1. The axis of the guide rod 6 is parallel to the axis of the double-headed screw 2.
[0032] The above two "V"-shaped docking plates 1 are buckled and can be buckled at the joint of the two heating pipelines 10 to be butt-welded. The two "V"-shaped docking plates 1 are connected by double-headed bolts. By rotating the double-headed bolts, the two "V"-shaped docking plates 1 can be driven to move synchronously towards or away from each other, realizing the clamping or separation of the two heating pipelines 10. When the two "V"-shaped docking plates 1 are clamped, by cooperating with the adjustment of multiple adjusting rods 3, the gap between the two heating pipelines 10 is adjusted to a suitable position, so that the two heating pipelines 10 are kept coaxial as much as possible. After clamping, the ports of the two heating pipelines 10 are welded, reducing the phenomenon that the joints of the two heating pipelines 10 cannot be well aligned, resulting in the vibration of the heating pipelines 10.
[0033] In this embodiment, to facilitate the adjustment rod 3 to tightly press against the corresponding heating pipeline 10 and finely adjust the port position thereof, one end of the adjustment rod 3 located inside the "V"-shaped docking plate 1 is hinged with an arc-shaped plate 4. The radian of the arc-shaped plate 4 is adapted to the heating pipeline 10, which can increase the contact area with the heating pipeline 10 and better press against the heating pipeline 10, and there will be no phenomenon of small contact points of the adjustment rod 3 and slipping.
[0034] See Figure 1 and Figure 4 As shown, to facilitate the adjustment of the gap between the two heating pipelines 10 to be the same, a leveling rod 7 is slidably connected to the "V"-shaped docking plate 1, and the sliding direction is parallel to the length direction of the parallel double-headed screw 2. One end of the leveling rod 7 passing through the "V"-shaped docking plate 1 is provided with a clip 8. The clip 8 can extend into the gap between the two heating pipelines 10. The width of the clip 8 does not affect the welding of the two heating pipelines 10. After several welding points are pre-welded on the two heating pipelines 10, the clip 8 can be taken out. Regarding the thickness of the clip 8, the thickness of the clip 8 is 0.2-2 mm, which can meet the welding of medium and small-sized heating pipelines 10 and is also convenient for taking out the clip 8. Before the fine adjustment of the two "V"-shaped docking plates 1, the clip 8 can be first arranged between the ports of the two heating pipelines 10. A tension spring 9 is sleeved on the leveling rod 7, and the tension spring 9 is located on the "V"-shaped docking plate 1. By means of the tension spring 9, it can be avoided that the clip 8 disengages from the gap between the two heating pipelines 10 when the two "V"-shaped docking plates 1 clamp the heating pipelines 10.
