[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0026] Embodiment 1:

[0027] As shown in the figure, the utility model proposes a quick pipe joint device, including two arc-shaped clamp arms 1, one end of the two clamp arms 1 is hinged to each other, the other end of the two clamp arms 1 is provided with a hanging ear 111 facing outward, and a locking member 2 is detachably connected between the two hanging ears 111. Specifically, each clamp arm 1 includes two arc-shaped plates 11 arranged in parallel, and a plurality of connecting plates 12 are vertically fixedly connected between the two arc-shaped plates 11. The ends of one side of the arc-shaped plates 11 on the two clamp arms 1 are hinged to each other; the hanging ear 111 is provided at the other end of the two arc-shaped plates 11, and each end of the arc-shaped plate 11 is provided with a corresponding hanging ear 111.

[0028] The locking member 2 includes a frame, a movable rod and a jack 26. The frame includes two parallel fixed rods 21. A hanging rod 22 is perpendicular to the two fixed rods 21 and fixedly connected to one end thereof. A sleeve 24 is slidably sleeved in the middle of the two fixed rods 21. A pressure rod 23 is parallel to the hanging rod 22 and fixedly connected between the two sleeves 24. A mounting plate 25 is fixedly connected between the other ends of the two fixed rods 21. The jack 26 is mounted on the mounting plate 25 and its piston rod is fixedly connected to the pressure rod 23. The hanging rod 22 is clamped on the hanging ear 111 of one of the clamp arms 1, and the pressure rod 23 is clamped on the hanging ear 111 of the other clamp arm 1.

[0029] When the device is used, the two clamp arms 1 cooperate to clamp and fix the pipe mouth of the pipeline 4, and the arc plates 11 on the same side of the two clamp arms 1 respectively clamp the corresponding pipe mouths, and the gap between the pipe mouths of the two pipes 4 is in the middle of the clamp arms 1. When the clamp arm 1 is fixed, the hanging rod 22 is first hooked and clamped into the hanging ear 111 of the clamp arm 1 on one side, and the jack 26 is driven to make its piston rod push the pressure rod 23 and clamp it into the hanging ear 111 of the clamp arm 1 on the other side, and the two clamp arms 1 are squeezed to effectively fix the pipe mouth, so that the central axis of the pipe mouth is kept in the same straight line, the pipe mouth is aligned, and the welding quality is improved.

[0030] The clamp arm 1 and the locking member 2 of the device are a split-type detachable structure, which makes it more convenient to carry and transport when transporting between different pipe opening welding points.

[0031] Embodiment 2:

[0032] The difference from the above embodiment lies in that in this embodiment, a through hole 120 is vertically penetrated through the connecting plate 12, and a limit block 31 for positioning the butt gap between the two pipes 4 is movably inserted in the through hole 120. One end of the limit block 31 is fixed by a fixing member on the connecting plate 12, and the other end extending through the through hole 120 toward the middle of the clamp arm 1 is provided with a plurality of positioning portions 310, and each positioning portion 310 has the same length and decreasing thickness.

[0033] According to the different butt joint gaps of the pipes 4, the limit block 31 is adjusted to extend toward the middle of the pipe 4, and the limit block 31 is fixed by a fixing piece so that the positioning portion 310 of the corresponding thickness is between the two pipes 4. The two pipes 4 are abutted against the two sides of the positioning portion 310 to effectively position the butt joint gap of the pipes 4. There is no need to repeatedly replace positioning blocks of different thicknesses. Only the positioning portion 310 on the limit block 31 needs to be adjusted, which is very convenient to use.

[0034] A fixing block 121 is provided on the connecting plate 12 outside the through hole 120, and a pin hole 312 corresponding to the installation position of each positioning part 310 below is vertically opened on the limiting block 31, and a pin 32 movably penetrated and arranged on the side of the fixing block 121 is inserted into the pin hole 312. The positioning part 310 corresponding to different docking gaps is adjusted according to construction requirements, and the limiting block 31 is locked by inserting the pin 32 penetrating the fixing block 121 and the limiting block 31 into the corresponding pin hole 312 above the positioning part 310, which can significantly improve the adjustment and fixing efficiency of the limiting block 31, and is simpler and more convenient to use.

[0035] In addition, a wedge block 33 with an inclined surface located above is slidably installed on the connecting plate 12 perpendicular to the limit block 31, and a through groove 311 is provided on the limit block 31 to match the wedge block 33. A pressure portion 331 is provided on the side end of the wedge block 33 away from the limit block 31. Since the limit block 31 needs to be pulled out of the butt joint after the pipe 4 is tightened and before welding, and the pipes 4 on both sides abut the limit block 31 to position, the limit block 31 will be clamped, making it difficult to pull out the limit block 31. In this device, a hammer or other tool can be used to knock the pressure portion 331 on the side end of the wedge block 33, and the limit block 31 can be lifted out of the through hole 120 through the cooperation between the wedge block 33 and the through groove 311, so that the limit block 31 can be easily taken out from between the two pipes 4, which is more convenient to use.

[0036] Specifically, a dovetail groove 330 is provided at the bottom of the wedge block 33, and a slide rail 122 is provided above the connecting plate 12 to slide with the dovetail groove 330. The installation direction of the slide rail 122 is perpendicular to the limiting block 31, so that the wedge block 33 can only be carried into the through groove 311 along the direction of the slide rail 122, which can effectively limit the movement direction of the wedge block 33 and prevent the wedge block 33 from being deflected and stuck when the wedge block 33 is knocked into the through groove 311. After the wedge block 33 is used, it can be removed from the slide rail 122 to avoid loss.

[0037] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive. Although the present application is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to perform equivalent replacement of some of the technical features therein.
