[0062] A through groove suitable for passing through the cutting saw blade 5 and intersecting with the guiding channel in position is provided on the workbench 1;

[0063] The telescopic drive source 4 is suitable for telescoping through the telescopic rod, so that the swinging support plate 2 swings around the connecting frame, driving the rotary drive source 3 and the cutting saw blade 5 on the rotary drive source 3 to pass through the through groove of the workbench 1.

[0064] In this embodiment, as Figure 1 and Figure 3 shown, first, a connecting frame is set on the workbench 1, then the swinging support plate 2 is hinged on the connecting frame, by installing the telescopic drive source 4 on the swinging support plate 2 and controlling the swing of the swinging support plate 2 through the telescopic rod of the telescopic drive source 4, the cutting saw blade 5 is realized to pass through the through groove on the workbench 1, and then the rotary drive source 3 is installed on the swinging support plate 2, and the cutting saw blade 5 is driven to rotate by the rotary drive source 3 to complete the cutting of the pipe.

[0065] Specifically, as Figure 1 and Figure 4 shown, the pipe lifting and cutting device further includes a pipe guiding assembly, and the pipe guiding assembly can be the following structure, including:

[0066] Four guiding plates 6, which are vertically installed on the workbench 1 along the guiding channel.

[0067] In this embodiment, as Figure 1 and Figure 4As shown, the main function of the pipe guiding assembly is to ensure that the pipe maintains the correct position and direction during the cutting process. The four guiding plates 6 are divided into two groups and are respectively arranged on both sides of the guiding channel centered on the through groove of the workbench 1. Waist-shaped grooves are provided on the guiding plates 6, and mounting holes are provided on the workbench 1. The width of a group of guiding plates 6 on the workbench 1 can be adjusted through the waist-shaped grooves. In addition, adjustable rollers or sliders can be installed on the inner side of the guiding plates 6 to reduce the friction between the pipe and the guiding plates 6 and facilitate the smooth conveyance of the pipe. Secondly, trumpet-shaped openings are also provided at the inlet and outlet of the guiding plates 6 for easy access.

[0068] In some embodiments, the number of guiding plates 6 is not limited to four and can be set according to specific requirements.

[0069] Specifically, as Figures 1-3 shown, the pipe lifting and cutting equipment further includes a protective cover 7, and the protective cover 7 is installed on the lower surface of the workbench 1;

[0070] A protective space suitable for accommodating the cutting saw blade 5 is provided inside the protective cover 7;

[0071] The cutting saw blade 5 is arranged in the protective space of the protective cover 7;

[0072] An arc-shaped groove is provided on the side surface of the protective cover 7;

[0078] In addition, for the protective cover 7, transparent materials can be considered to make part of the protective cover, allowing the operator to observe the cutting process under safe conditions. Lighting devices can also be installed on the protective cover 7 to improve the visibility of the working area.

[0079] Specifically, as Figures 1-2 shown, the pipe lifting and cutting equipment further includes a drag chain assembly 8, and one end of the drag chain assembly 8 is connected to the workbench 1;

[0080] The drag chain assembly 8 is provided with a hollow channel, and the hollow channel is suitable for accommodating the cable for supplying power to the rotary drive source 3.

[0081] In this embodiment, as Figures 1-2 shown, the main function of the drag chain assembly 8 is to accommodate the cables and air pipes provided by the rotary drive source 3 and the telescopic drive source 4. The design of the drag chain assembly 8 not only protects the cables, but also ensures the flexibility and durability of the cables during the movement of the equipment.

[0082] Specifically, as Figures 1-2 and Figures 4-5 shown, the pipe lifting and cutting equipment further includes a support device, and the support device can have the following structure, including:

[0083] A height adjustment mechanism 101, and the height adjustment mechanism 101 includes an adjustment component 104 suitable for moving along the vertical direction;

[0084] A cone pulley 102, and the cone pulley 102 is rotatably installed at the upper end of the adjustment component 104 of the height adjustment mechanism 101;

[0085] The height adjustment mechanism 101 is suitable for being actuated to adjust the height position of the cone pulley 102 relative to the workbench 1 through the adjustment component 104.

[0086] Specifically, as Figures 1-2 and Figures 4-5 shown, the height adjustment mechanism 101 further includes:

[0087] A fixed bracket 103, the fixed bracket 103 is installed on the workbench 1, the fixed bracket 103 is provided with an adjustment guide groove along the vertical direction, and the fixed bracket 103 is provided with a threaded hole communicated with the adjustment guide groove;

[0088] The adjusting member 104 is slidably mounted in the adjusting guide groove;

[0089] A locking assembly 105, the locking assembly 105 passes through the threaded hole of the fixed bracket 103 and abuts against the adjusting member 104. The locking assembly 105 is adapted to be actuated to release the abutment against the adjusting member 104 to adjust the height position of the adjusting member 104 in the adjusting guide groove;

[0090] The conical pulley 102 is rotatably mounted at the upper end of the adjusting member 104.

[0091] In this embodiment, as Figures 1-2 and Figures 4-5 shown, the main function of the support device is to provide stable support for the pipe and can flexibly adjust the support height according to the diameter of different pipes. First, the operator releases the adjusting member 104 by loosening the locking assembly 105 according to the diameter of the pipe to be cut. Then, slide the adjusting member 104 up and down along the adjusting guide groove on the fixed bracket 103 until the conical pulley 102 reaches the appropriate height position. Finally, re-lock the locking assembly 105 to fix the adjusting member 104 in the required position to adapt to pipes of different specifications. When the pipe is placed on the conical pulley 102, the conical pulley 102 can rotate freely as the pipe moves, effectively reducing the friction force and facilitating the conveying and positioning of the pipe. In addition, the conical structure of the conical pulley 102 can adapt to pipes of different diameters and provide a stable support point.

[0092] Specifically, as Figure 1 and Figure 3 and Figure 5 shown, a support working frame 11 is further provided on the workbench 1;

[0093] The pipe lifting and cutting device further includes a pressing assembly, and the pressing assembly can be the following structure, including:

[0094] Two telescopic drivers 91, the telescopic drivers 91 are fixedly mounted on the support working frame 11;

[0095] The telescopic driver 91 is provided with a telescopic driving rod;

[0096] A pressing block 92, the pressing block 92 is fixedly connected to the end of the driving rod of the telescopic driver 91;

[0097] The pressing block 92 is provided with an abutting surface matching the outer surface of the pipe;

[0098] The telescopic driver 91 is adapted to drive the pressing block 92 to abut against the pipe through the driving rod.

[0099] In this embodiment, as Figure 1 and Figure 3 and Figure 5As shown, the main function of the pressing assembly is to fix the pipe during the cutting process, prevent the pipe from moving or vibrating, so as to ensure the cutting accuracy and quality. The telescopic driver 91 can be pneumatic telescopic, and in some embodiments, it can also be a hydraulic driver. First, place the pipe to be cut at the designated position on the workbench 1. Then, start the telescopic driver 91, and the driving rod extends downward, driving the pressing block 92 to move towards the pipe. The abutting surface of the pressing block 92 is designed to match the shape of the outer surface of the pipe, such as a V shape, and in some embodiments, it can also be an arc shape. This can increase the contact area, disperse the pressure, and avoid damaging the surface of the pipe. When the pressing block 92 contacts the pipe and applies appropriate pressure, the pipe is firmly fixed on the workbench 1.

[0100] In some embodiments, the number of telescopic drivers 91 is not limited to two and can be set according to specific requirements.

[0101] Specifically, as Figure 1 and Figure 3 and Figure 4 As shown, a group of partition plates 12 vertically installed on both sides of the through groove are also provided on the support workbench 11, and through grooves suitable for the pipe to pass through are provided on the partition plates 12;

The dust and debris generated during the cutting process are controlled. The partition plate 12 vertically installed on the support workbench 11 plays a role in separating the working area, and the through groove on it allows the pipe to pass through smoothly. The flexible bristles in the dust-proof assembly 120 are installed on the partition plate 12, covering the through groove, forming a flexible barrier. When the pipe passes through, the flexible bristles will automatically separate to allow the pipe to pass through, while still maintaining the blocking effect on the dust.

[0107] In some embodiments, the number of dust-proof assemblies 120 is not limited to one group and can be set according to specific requirements.

[0108] Specifically, as Figure 1 As shown, the rotary drive source 3 is a motor.

[0109] In this embodiment, as Figure 1 and Figure 3 and Figure 5 shown, both the telescopic drive source 4 and the telescopic driver 91 can be cylinders. This embodiment also has a PLC, which is connected to the encoder that records the conveying length of the production line. When the length recorded by the encoder reaches the set value, the PLC sends a signal to the solenoid valve that controls the telescopic driver 91. The solenoid valve controls the telescopic driver 91 to press downwards, and then controls the telescopic drive source 4 to contract. The cutting saw blade 5 extends out of the through groove, and at the same time, the rotary drive source 3 drives the cutting saw blade 5 to rotate, and starts to continue cutting the pipe. After the cutting is completed, the telescopic driver 91 contracts, releases the pressing, the telescopic drive source 4 drives the cutting saw blade 5 to withdraw from the through groove, and the rotary drive source 3 is turned off. One-time cutting of the pipe is completed.

[0110] This embodiment is suitable for the rapid cutting of small pipes on a high-speed production line, and is more suitable for thick-walled pipes. The cutting saw blade 5 can select the diameter of the cutting saw blade 5 according to the outer diameter of different pipes during the production process.
