[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, a pipe pile cutting device includes two support seats 1 3 and a support seat 2 4 which are symmetrically distributed front and back, the upper ends of the two support seats 1 3 are fixedly connected with clamping assemblies 2, the upper parts of the two clamping assemblies 2 are commonly provided with square pipe piles 1, the upper ends of the support seats 2 4 are fixedly connected with a receiving assembly 5, the upper right end of the receiving assembly 5 is fixedly connected with a lifting assembly 6, and the left part of the lifting assembly 6 is provided with a cutting saw 7.

[0027] The main structural components of the cutting saw 7 mentioned above include a frame, a workbench, a tool, a tool holder and a control system. The frame is the supporting structure of the cutting machine and has sufficient rigidity and stability. The workbench is a platform for placing workpieces or materials, and the height can be adjusted to meet different cutting requirements. The tool is the core component of the cutting machine and can be in the form of a blade, a knife or a cutter wheel. The tool holder is the load-bearing component of the tool, and usually has the function of adjusting the cutting angle and cutting depth. The control system is the brain of the cutting machine, which can realize the automatic operation and precise control of the cutting machine.

[0028] The power source of the cutting machine usually comes in the form of electric motors, hydraulic systems or pneumatic systems. Electric motors are the most common power source, which drives the movement of the cutting machine by converting electrical energy into mechanical energy. Hydraulic systems use the pressure of liquid to transmit power and are usually used for cutting tasks that require high power and force. Pneumatic systems use the pressure of gas to transmit power and are suitable for cutting work in some special environments.

[0029] In the specific implementation process of this scheme, first adjust the distance between the two support seats 3, then use a crane to mobilize the square pipe pile 1 and place it on the upper part of the clamping components 2 on both sides. When the square pipe pile 1 is placed on the upper part of the clamping component 2, the clamping component 2 clamps it immediately. At this time, the receiving component 5 also supports the middle position of the square pipe pile 1. Then, the lifting component 6 can be started to use the cutting saw 7 to cut the square pipe pile 1. After the square pipe pile 1 is cut into the front and rear ends, the support of the receiving component 5 can still keep the stability of the square pipe pile 1 at the front and rear ends.

[0030] Specifically, in order to facilitate the clamping of the square pipe pile 1 and improve the efficiency of the preparatory work before cutting, refer to Figure 2 and Figure 3The clamping assembly 2 includes a sleeve shell 21 fixedly connected to the support seat 3, a fixing plate 25 fixedly connected to the upper end of the sleeve shell 21, a support frame 22 that sequentially penetrates the sleeve shell 21 and the fixing plate 25 and extends to the upper part of the upper end of the fixing plate 25 is slidably connected to the top wall of the inner surface of the sleeve shell 21, a spring 1 is fixedly connected to the lower end of the support frame 22 and the bottom wall of the inner surface of the sleeve shell 21, a slide groove is provided at the left and right ends of the sleeve shell 21, and the left and right sides of the support frame 22 are slidably connected to the slide groove on the same side, a connecting plate 23 is fixedly connected to the left and right ends of the fixing plate 25, and the upper ends of the two connecting plates 23 are rotatably connected to the clamping plate 24;

[0031] For further information, see Figure 2 The left and right vertical parts of the support frame 22 both penetrate the connecting plate 23 on the same side and are slidably connected to the connecting plate 23 on the same side. The upper ends of the left and right vertical parts of the support frame 22 are fixedly connected with balls. The outer surfaces of the two balls are rotatably connected with connecting columns 26. The two connecting columns 26 are slidably connected to the clamping plate 24 on the same side. A spring 2 is fixedly connected between the two connecting plates 23 and the connecting columns 26 on the same side and is sleeved on the outside of the vertical part of the support frame 22 on the same side.

[0032] For further information, see Figure 2 A receiving plate 221 is fixedly connected to the middle of the upper end of the support frame 22, and a left-right symmetrical spring three 222 is fixedly connected between the receiving plate 221 and the fixing plate 25;

[0033] It can be seen that when the square pipe pile 1 is placed on the upper ends of the receiving plates 221 on both sides, under the gravity of the square pipe pile 1, the receiving plates 221 will be pressed to squeeze the spring three 222, so that the spring three 222 on the front and rear sides are compressed. At this time, the middle part of the support frame 22 gradually slides into the inside of the casing 1 21 to compress the spring one. At this time, the support frame 22 gradually moves downward, slides in the slide grooves at the left and right ends of the casing 1 21 on the same side, and drives the vertical parts on the left and right sides of the support frame 22 to move downward, and slide inside the connecting plate 23 on the same side. At this time, the clamping plate 24 will be driven to move downward through the ball and the connecting column 26 until the clamping plates 24 on both sides clamp the square pipe pile 1;

[0034] During the downward movement of the splint 24, the two connecting columns 26 on the same side will slide toward the side where the two splints 24 are away from each other, and at the same time, the spring 2 will be compressed, so that the splint 24 can move downward smoothly, squeeze the outer surface of the square pipe pile 1, and clamp it. When the square pipe pile 1 is lifted, the pressure on the receiving plate 221 is released. At this time, the components of the clamping assembly 2 that move downward will be reset under the action of the spring on the same side. During the resetting process of the splint 24, the connecting column 26 will slide again at the lower end of the splint 24 until it is reset.

[0035] Specifically, in order to improve the efficiency of cutting, refer to Figure 4 and Figure 5 The receiving assembly 5 includes a second casing 51, and two springs 52 are fixedly connected to the center of the bottom wall of the inner surface of the second casing 51 symmetrically. The upper ends of the two springs 52 are fixedly connected to a support member 53, and the upper front side and the upper rear side of the support member 53 are fixedly connected to a pressure plate 54;

[0036] For further information, see Figure 4 , the second housing 51 is fixedly connected to the second support seat 4, and the support member 53 is slidably connected to the fourth spring 52;

[0037] For further information, see Figure 4 The lifting assembly 6 includes an L-shaped fixing plate 61, a motor 65 is fixedly connected to the lower rear end of the L-shaped fixing plate 61, the motor 65 is fixedly connected to a threaded rod 63 through a coupling at the output end, a sliding rod 64 is fixedly connected to the front end of the L-shaped fixing plate 61, and a fixing member 62 is provided on the outer surfaces of the threaded rod 63 and the sliding rod 64;

[0038] For further information, see Figure 4 , the L-shaped fixing plate 61 is fixedly connected to the support member 53, the threaded rod 63 is rotatably connected to the L-shaped fixing plate 61, the fixing member 62 is threadedly connected to the threaded rod 63, the fixing member 62 is slidably connected to the slide bar 64, and the cutting saw 7 is fixedly connected to the fixing member 62;

[0039] The position of the cutting saw 7 is far away from the upper end of the square pipe pile 1 to avoid affecting the placement and fixation of the square pipe pile 1.

[0040] It can be seen that when the square pipe pile 1 is placed on the upper end of the receiving plate 221, the middle part of the square pipe pile 1 will also be squeezed on the upper ends of the two pressing plates 54. At this time, the two springs 52 will be compressed under the action of the gravity of the square pipe pile 1, so that the support member 53 slides downward, thereby adjusting the height of the pressing plate 54 to complete the support of the square pipe pile 1. After the support is completed, the motor 65 can be started to drive the threaded rod 63 to start rotating, which can drive the fixing member 62 to slide up and down. At this time, the cutting saw 7 is started to cut the square pipe pile 1. In the process of the fixing member 62 moving up and down, the sliding rod 64 is used to guide the fixing member 62 to ensure the stability of the fixing member 62 in the process of moving up and down, and to ensure the stability of the square pipe pile 1 when cutting;

[0041] In addition, the receiving component 5 is used to support the middle part of the square pipe pile 1, so that after the middle part of the receiving component 5 is cut, the square pipe piles 1 on both sides before and after the cutting can still be supported, so as to avoid damage to the device and the square pipe pile 1 when the square pipe pile 1 falls to the ground. At the same time, the two springs four 52 are used to buffer the pressure on the support member 53. The support member 53 slides downward on the inner surface of the spring four 52 according to the height of the receiving plate 221. There is no need to manually adjust the height of the receiving component 5 according to the height of the clamping component 2 to provide support, which saves time and effort.

[0042] It should be noted that the specific installation method of the motor 65, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.
