[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0030] like Figure 1-Figure 4 As shown:

[0031] An embodiment of the present application provides a heating pipe docking device, comprising two clamp rings 1 in an arc-shaped structure, one end of the two clamp rings 1 is hinged, and the other ends of the two clamp rings 1 are detachably fixedly connected through a locking connection structure 6. Specifically, one end of one clamp ring 1 is hinged to one end of the other clamp ring 1 through a hinge structure.

[0032] Each clamp ring 1 is equipped with an arc-shaped driving mechanism 5. The driving mechanism 5 is connected to a plurality of equally spaced pressure strips 2, and the driving mechanism 5 can drive all the pressure strips 2 connected thereto to move synchronously along the radial direction of the clamp ring 1.

[0033] When in use, first operate the driving mechanism 5 on each clamp ring 1 to move all the pressure strips 2 to the appropriate position to adapt to the pipe diameter of the heating pipe 4 to be matched, and then put the two clamp rings 1 on the two heating pipes 4 to be matched at the same time, and then fix the other ends of the two clamp rings 1 through the locking connection structure 6, so that all the pressure strips 2 clamp the ends of the two heating pipes 4 at the same time. When all the pressure strips 2 clamp the two heating pipes 4 at the same time, adjust the positions of the two heating pipes 4 so that the straightness and matching gap of the two pipes meet the requirements.

[0034] The heating pipe docking device provided in the present embodiment has an arc-shaped driving mechanism 5 installed on each clamping ring 1, and the driving mechanism 5 is connected to a plurality of equally spaced pressure strips 2, and the driving mechanism 5 can drive all the pressure strips 2 connected thereto to move synchronously along the radial direction of the clamping ring 1, so that when it is used to dock heating pipes 4 of different sizes, only two driving mechanisms 5 need to be operated to complete the position adjustment of all the pressure strips 2. Compared with the existing adjustment method of disassembling and installing each bolt one by one, it is not only convenient to operate, but also can shorten the time used for the entire adjustment process, thereby improving the adjustment efficiency.

[0035] In some embodiments of the present application, the clamp ring 1 is a hollow structure, and the driving mechanism 5 is located in the hollow position of the clamp ring 1, thereby reducing the occupied space.

[0036] In some embodiments of the present application, the driving mechanism 5 includes two arc plates 51 that can move toward or away from each other along the axial direction of the clamp ring 1, and the two arc plates 51 are symmetrically distributed and installed in the hollow position of the clamp ring 1. Each pressure strip 2 is rotatably connected to two support frames 52 that are symmetrically distributed and correspond one to one with the two arc plates 51, and each support frame 52 is rotatably connected to the corresponding arc plate 51. Specifically, one end of the support frame 52 is rotatably connected to the arc plate 51 through a hinge structure, and the other end of the support frame 52 is rotatably connected to the arc plate 51 through a hinge structure. The support frame 52 is tilted relative to the pressure strip 2 to avoid jamming when the support frame 52 rotates.

[0037] In this embodiment, the two arc-shaped plates 51 are located between one ends of the two support frames 52 .

[0038] When in use, after operating the two curved plates 51 to move toward each other, each curved plate 51 drives the support frame 52 connected thereto to move and rotate, that is, while the other ends of the two symmetrical support frames 52 move toward each other, the two symmetrical support frames 52 rotate, and drive the pressure strips 2 to move radially along the clamping ring 1 in the direction close to the curved plate 51, so that all the pressure strips 2 can clamp the larger heating pipe 4 at the same time; after operating the two curved plates 51 to move away from each other, each curved plate 51 drives the support frame 52 connected thereto to move and rotate, that is, while the other ends of the two symmetrical support frames 52 move away from each other, the two symmetrical support frames 52 rotate, and drive the pressure strips 2 to move radially along the clamping ring 1 in the direction away from the curved plate 51, so that all the pressure strips 2 can clamp the smaller heating pipe 4 at the same time, and then all the clamping strips can clamp heating pipes 4 of different sizes, so that they can be used for the docking work of heating pipes 4 of different sizes, and the position adjustment work of all the pressure strips 2 on each clamping ring 1 can be completed by only operating the two curved plates 51 to move toward or away from each other.

[0039] In some embodiments of the present application, two symmetrically distributed slide bars 53 are fixed to the hollow position of the clamp ring 1. Specifically, both ends of the slide bars 53 simultaneously penetrate the clamp ring 1 and are welded and fixed to the clamp ring 1. Each slide bar 53 simultaneously penetrates two arc plates 51 and is slidably connected to the two arc plates 51.

[0040] A rotatable drive shaft 54 ​​is installed in the hollow position of the clamp ring 1. Specifically, both ends of the drive shaft 54 ​​are rotatably connected to the clamp ring 1 through bearings, and two external thread structures with opposite spiral directions are provided on the drive shaft 54, one of which penetrates one of the arc plates 51 and is threadedly connected to the arc plate 51, and the other external thread structure penetrates the other arc plate 51 and is threadedly connected to the arc plate 51, and then only the drive shaft 54 ​​needs to be rotated to realize the movement of the two arc plates 51 towards or away from each other, that is, the position adjustment work of all the pressure strips 2 on the clamp ring 1 can be adjusted by rotating the drive shaft 54.

[0041] In order to facilitate the rotation of the drive shaft 54 ​​and reduce the occupied space, in some embodiments of the present application, a knob 55 is sleeved and fixed at the middle position of the drive shaft 54 ​​.

[0042] In some embodiments of the present application, two symmetrically distributed and perpendicular limiting rods 3 are fixed on each pressure strip 2, and the limiting rods 3 pass through the corresponding clamping ring 1 and are slidably connected to the clamping ring 1, thereby limiting the pressure strip 2 so that the pressure strip 2 can move steadily along the radial direction of the clamping ring 1.

[0043] In some embodiments of the present application, one of the limit rods 3 on each clamp ring 1 is provided with scale lines distributed radially along the clamp ring 1 (as shown in the figure), so that the staff can determine the moving distance of the pressure strip 2, and then make the moving distance of all pressure strips 2 the same.

[0044] In this embodiment, after the pressure strip 2 is located at the minimum distance close to the arc plate 51, the inner edge of the clamp ring 1 coincides with the starting position of the scale line.

[0045] In some embodiments of the present application, the locking connection structure 6 includes a jack 61 and a U-shaped frame 62. The jack 61 is fixed to the other end of one of the clamping rings 1, and the two vertical section ends of the U-shaped frame 62 are rotationally connected to the other end of the other clamping ring 1 at the same time.

[0046] A socket is provided on the horizontal section of the U-shaped frame 62, and the socket can be rotated to the top of the jack 61, and the free end of the jack 61 can be inserted into the socket and push the U-shaped frame 62 to move upward to achieve the fixation between the other ends of the two clamp rings 1.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
