[0019] As Figures 1-3As shown, the embodiment provides a steel pipe clamping device, which comprises a base plate 1, and a first support 2 and a second support 3 fixedly installed on the base plate 1, and an upwardly open arc-shaped groove 4 is arranged on each of the first support 2 and the second support 3, the clamping structure further comprises a first arc-shaped pressing plate 5, and first connecting lug plates 6 are fixedly arranged at both ends of the first arc-shaped pressing plate 5 respectively, and first fastening rods 7 are threadedly connected to the two first connecting lug plates 6 respectively, and first threaded holes are further arranged on the base plate 1 for threadedly connecting the two first fastening rods 7, and the two first threaded holes are located between the first support 2 and the second support 3 and close to the first support 2. The first support 2 and the second support 3 are arranged for horizontally placing the steel pipe 8, and the first arc-shaped pressing plate 5 is arranged for providing downward pressing on the steel pipe 8 from above to the below, that is, the first arc-shaped pressing plate 5 has the same arc-shaped opening as the arc-shaped recess, and the arc-shaped opening is downwardly surrounded with the arc-shaped groove 4 around the steel pipe 8, so that one end of the steel pipe 8 is clamped, and the other end only needs to be supported upwardly by the second support 3, in the process, as long as the steel pipe 8 can be placed in the arc-shaped groove 4 of the first support 2 and the second support 3, clamping can be performed, and more small-sized steel pipes 8 have better adaptability, thus solving the problem of poor universality of the clamping device for clamping the steel pipe 8 in the prior art. In particular, a second arc-shaped pressing plate 9 can also be arranged on the base plate 1 on the other side of the first support 2, the second arc-shaped pressing plate 9 also has the same arc-shaped opening as the arc-shaped recess, and can provide downward pressing downwardly like the first arc-shaped pressing plate 5, so as to assist the first arc-shaped pressing plate 5 to limit the upper end of the steel pipe 8, and at the same time, balanced downward pressing force can also be provided on both sides of the first support 2 (the structural shape of the first arc-shaped pressing plate 5 and the second arc-shaped pressing plate 9 is the same, and the distance between them and the first support 2 on both sides is also equal), and then each first fastening rod 7 and second fastening rod 11 can be locked (similarly, second connecting lug plates 10 are also fixedly connected at both ends of the second arc-shaped pressing plate 9, and corresponding second fastening rods 11 and second threaded holes are also arranged).

[0020] As Figures 1-3As shown, the first arc-shaped pressing plate 5 and the second arc-shaped pressing plate 9 and the arc-shaped recess 4 are all open structures, so that they mainly contact the middle section of the steel pipe 8 and are symmetric and balanced in force, and can accommodate more sizes of the steel pipe 8, more specifically, the arc-shaped openings on the first arc-shaped pressing plate 5 and the second arc-shaped pressing plate 9 are arc-shaped transitions with the corresponding two first connecting ear plates 6 or two second connecting ear plates 10, similarly, the two ends of the arc-shaped recess 4 are arc-shaped transitions with the top surfaces of the corresponding first supporting seat 2 or second supporting seat 3, so that the steel pipe 8 can avoid the corner collision in the process of entering the corresponding arc-shaped opening.
