DETAILED DESCRIPTION

[0016] The utility model is described in detail below with reference to the accompanying drawings:

[0017] like Figure 1As shown, a steel pipe clamp for a concrete support working platform in a mine chamber comprises a first clamping rod 1, one end of which is fixed with a first arc rod 2 having a semicircular structure. In this embodiment, the semicircle diameter of the first arc rod 2 is 89 mm, and the first arc rod 2 is used to clamp a seamless steel pipe of Φ89 mm. The first arc rod 2 is connected to a second clamping rod 3 which is arranged parallel to the first clamping rod 1, and the distance between the first clamping rod 1 and the second clamping rod 3 is 89 mm. The end of the first clamping rod 1 away from the first arc rod 2 is fixed with a second arc rod 4 having a semicircular structure. The second arc rod 4 is connected to a third clamping rod 5 which is arranged parallel to the first clamping rod 1, and the semicircle diameter of the second arc rod 5 is 108 mm. The end of the second clamping rod 3 away from the first arc rod 2 is fixed with a third arc rod 6. The shape and size of the rod 6 are consistent with those of the second arc rod 4. The plane where the second arc rod 4 is located is parallel to the plane where the third arc rod 6 is located. In addition, the plane where the first arc rod 2 is located is perpendicular to the plane where the second arc rod 4 is located. The second arc rod 5 and the third arc rod 6 are used to clamp the Φ108mm seamless steel pipe. The third arc rod 6 has a fourth clamping rod 7 which is parallel to the third clamping rod 5. The lengths of the first clamping rod 1 and the second clamping rod 3 are both 98.5mm, which is consistent with the sum of the radii of the Φ89mm and Φ108mm seamless steel pipes. After the Φ108mm seamless steel pipe is clamped in the second arc rod 4 and the third arc rod 6, the Φ89mm seamless steel pipe can be clamped in the first arc rod 2. At this time, the Φ89mm seamless steel and the Φ108mm seamless steel pipe are connected and are perpendicular to each other.

[0018] An arc-shaped fixing plate 8 is connected between the third clamping rod 5 and the fourth clamping rod 7. The fixing plate 8 is used for fixing the Φ89mm seamless steel so that the Φ89mm seamless steel is fixed firmly. Specifically, a first screw 9 is provided at one end of the third clamping rod 5 away from the second arc-shaped rod 4, and a second screw 10 is provided at one end of the fourth clamping rod 7 away from the third arc-shaped rod 6. A first through hole 11 is provided at one end of the fixing plate 8 and a second through hole 12 is provided at the other end. The first screw 9 passes through the first through hole 11, and the second screw 10 passes through the second through hole 12. A first nut 13 is provided on the first screw 9, and a second nut 14 is provided on the second screw 110. After the fixing plate 8 is installed, the Φ89mm seamless steel can be fixed so that the Φ89mm seamless steel pipe is fixed firmly.

[0019] The usage of the utility model is as follows:

[0020] First, place the Φ108mm seamless steel pipe 16 into the second arc rod 4 and the third arc rod 6, and then insert the Φ89mm seamless steel pipe 15 into the first arc rod 2, so that the Φ89mm seamless steel pipe 15 and the Φ108mm seamless steel pipe 16 are in a vertical state during insertion, and then install the clamping plate 8 on the first screw rod 9 and the second screw rod 10, and tighten the first nut 13 and the second nut 14. After the installation is completed, the three points on the Φ89mm seamless steel pipe 15 are respectively subjected to the external forces applied by the first arc rod 2, the clamping plate 8 and the Φ108mm seamless steel pipe 16, and the three points on the Φ108mm seamless steel pipe 16 are respectively subjected to the external forces applied by the second arc rod 4, the third arc rod 6 and the Φ89mm seamless steel pipe 16, which can keep the Φ89mm15 and the Φ108mm seamless steel pipe 16 firmly fixed (such as Figure 2 as shown).

[0021] The clamp has a simple structure, is mainly composed of a straight rod and an arc rod, can be made by bending steel bars, has low cost and high processing speed, can effectively save costs, and is suitable for clamping small batches of special-shaped pipes.
