[0012] The present invention is not limited by the following embodiments, and specific implementation methods can be determined based on the technical solution of the present invention and actual conditions.

[0013] In this utility model, for the convenience of description, the relative position relationship of each component is described based on the Figure 1 For example, the positional relationships of front, back, up, down, left, and right are determined according to the layout directions of the drawings in the specification.

[0014] The present invention will be further described below in conjunction with the embodiments and accompanying drawings:

[0015] As attached Figure 1 As shown, the small tool for quick pipe unloading includes a telescopic rod, a mounting disc 1, a support claw 2 and a lockable universal joint 3. The two ends of the telescopic rod are connected to the mounting disc 1 through the lockable universal joint 3. A plurality of support claws 2 that can be extended or retracted along its radial direction are installed at intervals along the circumferential direction on the mounting disc 1; the support claw 2 is in the shape of a long rod, and a mounting groove is provided in the middle of one end of the support claw 2 close to the mounting disc 1. The support claw 2 is movably mounted on the mounting disc 1 through the mounting groove, and a first locking hole is provided on one side wall of the mounting groove. The first locking hole is threadedly connected to a first locking screw 4 whose end is against the mounting disc 1 to lock the support claw 2 and the mounting disc 1 together.

[0016] According to the needs, the universal joint 3 can adopt the existing well-known technology. In this embodiment, six claws 2 that can be extended or retracted in the radial direction are evenly spaced and installed on the mounting disc 1 in the circumferential direction. When the pipe is cut, first place the present application between the two end ports of the pipe to be cut, adjust the length of the telescopic rod, the angle of the mounting disc 1, and adjust the claws 2 to extend outward so that the claws 2 on the two mounting discs 1 are respectively against the two end ports of the original pipe to be cut, and then lock the universal joint 3. At this time, the angles of the two discs are consistent with the angles of the two end ports of the original pipe, and the length of the entire device is consistent with the spacing between the two end ports of the original pipe, that is, the angle and spacing data of the two end ports of the original pipe to be cut are "copied" by the present application, and then the claws 2 are adjusted to retract inward, and the present application is placed in the new pipe section to be assembled, and then the claws 2 are adjusted to extend outward until they are aligned with the new pipe. The inner walls of the segments are abutted against each other, and a cutting line is drawn on the inner wall of the new pipe segment along the support claw 2. The new pipe segment is cut and blanked along the cutting line, so that the angles of the two end ports of the new pipe segment after cutting are consistent with the angles of the two end ports of the original pipe, and the spacing between the two end ports of the new pipe segment is consistent with the spacing between the two end ports of the original pipe. Then the two ends of the new pipe are assembled and welded to the two ends of the original pipe. Compared with the existing pipeline cutting method, the setting of the present application can "copy" the angle and spacing data of the two end ports of the original pipeline to be cut to the new pipe segment to be assembled, thereby eliminating the need to obtain the data through multi-point measurement and calculation, greatly shortening the measurement and calculation time, and improving the pipeline cutting speed.

[0017] The above embodiments may be further optimized and / or improved according to actual needs:

[0018] As attached Figure 1 As shown, the telescopic rod includes an inner rod 5 and an outer rod 6 that is movably mounted on the outer side of the inner rod 5. The outer rod 6 is provided with a second locking hole. The second locking hole is internally threaded with a second locking screw 7, one end of which abuts against the inner rod 5 to lock the inner rod 5 and outer rod 6 together. The ends of the inner rod 5 and outer rod 6 that are separated from each other are respectively connected to a mounting disc 1 via a lockable universal joint 3. This facilitates locking of the telescopic rod.

[0019] As attached Figure 1 As shown, the end of the claw 2 away from the mounting disc 1 is provided with a V-shaped inclined surface 8 formed by the intersection of a first inclined surface and a second inclined surface, and the intersection line of the first inclined surface and the second inclined surface is parallel to the central axis of the mounting disc 1. This facilitates the claw 2 to abut against the inner wall of the pipe.

[0020] The above technical features constitute the best embodiment of the present invention, which has strong adaptability and best implementation effect. Non-essential technical features can be added or removed according to actual needs to meet the requirements of different situations.
