[0008] Preferably, a guide rod is fixedly connected to the outer wall of the cross bar, and the guide rod passes through the inner wall of the operating table and is slidably connected to the inner wall of the operating table, so as to protect the spring 1 and prevent the spring 1 from bending under the action of pressure.

[0009] Preferably, a spring 1 is fixedly connected to the outer wall of the cross bar, and one end of the spring 1 away from the cross bar is fixedly connected to the inner wall of the operating table.

[0010] Preferably, the movement rod is penetrated by the pressure rod and is slidably connected to the pressure rod, one end of the second spring is fixedly connected to the outer wall of the pressure rod, and the other end of the second spring is fixedly connected to the outer wall of the movement rod.

[0013] The utility model provides a construction steel pipe cutting device, which has the following beneficial effects:

[0014] (1) The construction steel pipe cutting device is provided with a clamping device. When the hydraulic cylinder drives the support plate to move downward, the sliding rod moves downward along the through groove. When the sliding rod moves a certain distance, the sliding rod exerts a force on the cross bar, so that the cross bar drives the moving rod to move toward the pipe body. When the moving rod moves a certain distance, the two sets of pressure rods designed at this time will squeeze the pipe body to clamp the pipe body. This design can prevent the pipe body from moving during cutting by clamping the pipe body, thereby improving the cutting accuracy of the pipe body.

[0015] (2) In the construction steel pipe cutting device, when the hydraulic cylinder drives the support plate to move upward, during this process, the force of the sliding rod on the cross bar disappears, and then the cross bar drives the pressure rod back to its original position under the elastic force of spring 1, thereby releasing the clamping of the pipe body.

[0027] like Figure 2-Figure 4As shown, there are two groups of moving rods 61 and pressure rods 65. The two groups of moving rods 61 and pressure rods 65 move toward the tube body 5 at the same time, so as to clamp the tube body 5. At the same time, each group of pressure rods 65 has two, which can be used to clamp the two ends of the cut part of the tube body 5.

[0028] Further, the cutting device 3 includes a hydraulic cylinder 31, the hydraulic cylinder 31 is fixedly connected to the outer wall of the support frame 2, the output end of the hydraulic cylinder 31 passes through the support frame 2 and is slidably connected to the inner wall of the support frame 2, the output end of the hydraulic cylinder 31 is fixedly connected to the support plate 32, the outer wall of the support plate 32 is fixedly connected to the motor 33 and the sliding rod 35, the output shaft of the motor 33 passes through the support plate 32 and is rotatably connected to the support plate 32, the output end of the motor 33 is fixedly connected to the cutting blade 34, and the sliding rod 35 is slidably connected to the through slot 13;
