Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a device for cutting both ends of a prefabricated direct-buried thermal insulation pipe, comprising: a support plate 1, a cutting movable groove 101 is provided on the surface of the support plate 1, an n-type support frame 102 is fixedly connected to the top of the support plate 1, four support blocks 104 are fixedly connected to the bottom of the support plate 1, one side of the four support blocks 104 is penetrated by a bearing hole 105, two opposite bearing holes 105 form a group, and clamping components 2 are provided inside the two groups of bearing holes 105, and a cutting component 3 is provided at the bottom of one end of the n-type support frame 102.

[0021] Specifically: the device is placed above the already fixed insulation pipe, and the insulation pipe is placed between the two sets of moving blocks 202. The knob bidirectional screw 201 and the knob worm 207 are rotated according to the diameter of the insulation pipe. The moving blocks 202 on both sides will follow the rotation of the knob bidirectional screw 201 and approach each other. The clamp 208 will rotate according to the knob worm 207, and change the angle around the fixed column 203, so that the clamp 208 fits the insulation pipe more closely, thereby achieving the purpose of initially fixing the device. The worker holds both sides of the n-type support frame 102 and starts the electric cylinder 301 and the motor 305 through an external controller to cut the insulation pipe flat. The device is designed in this way so that it can be fixed on the surface of insulation pipes of different diameters, thereby improving the practicality of the device. At the same time, the device is easy to hold and is more flexible and easy to move. When cutting, the worker can hold both sides of the n-type support frame 102 with both hands to prevent the device from sliding on the surface of the insulation pipe and affecting the cutting operation.

[0022] In one embodiment, two T-slots 103 are formed at the bottom of the support plate 1.

[0023] Specifically: the T-slot 103 is used to limit the movement of the moving block 202 .

[0024] In one embodiment, the clamping assembly 2 includes a knob bidirectional screw 201, and the surface thread sleeve of the knob bidirectional screw 201 is provided with two moving blocks 202, and two fixed columns 203 and a support plate 2 204 are fixedly connected on both sides of the inner cavity of the two moving blocks 202, and the surfaces of the four fixed columns 203 are provided with clamping claws 208 through bearing sleeves, and the sides of the two support plates 204 are penetrated with bearing holes 205, and one side of the two moving blocks 202 is penetrated with bearing holes 3 206, and the two bearing holes 205 and the two bearing holes 3 206 are evenly divided into two groups, and the interiors of the two groups of bearing holes 205 and the bearing holes 3 206 are embedded with knob worms 207 through bearings, and the four clamping claws 208 are grouped in pairs, and the surfaces of one end of the two groups of clamping claws 208 are meshingly connected to the surfaces of the two knob worms 207.

[0025] Specifically: the knob bidirectional screw 201 and the knob worm 207 are rotated according to the diameter of the insulation pipe. Since the moving block 202 is threadedly connected to the knob bidirectional screw 201, the moving blocks 202 on both sides will approach each other following the rotation of the knob bidirectional screw 201, and the clamping jaw 208 will change its angle around the fixed column 203 according to the rotation of the knob worm 207, so that the clamping jaw 208 fits the insulation pipe more closely, thereby achieving the purpose of initially fixing this device; the surface of one end of the clamping jaw 208 is circular in design, and a turbine tooth meshing with the knob worm 207 is arranged on the surface, which can be used in conjunction with the knob worm 207, and at the same time, only the knob worm 207 can drive the clamping jaw 208, and the clamping jaw 208 cannot drive the knob worm 207.

[0026] In one embodiment, the cutting assembly 3 includes an electric cylinder 301, the bottom of the electric cylinder 301 is fixedly connected to a cutting support shell 302, both sides of the cutting support shell 302 are penetrated with bearing holes 303, one side of the cutting support shell 302 is fixedly connected to a motor plate 304, the bottom of the motor plate 304 is fixedly connected to a motor 305, the output end of the motor 305 is embedded in the inside of the two bearing holes 303 through a bearing, the surface of the output end of the motor 305 is fixedly sleeved with a cutting blade 306, and the surface of the cutting blade 306 is movably embedded in the inside of the cutting support shell 302.

[0027] Specifically, a worker holds both sides of the n-shaped support frame 102 and starts the electric cylinder 301 and the motor 305 through an external controller, and the cutting blade 306 rotates following the output end of the motor 305 to cut the insulation pipe flat.

[0028] In one embodiment, the surfaces at both ends of the two knob bidirectional screw rods 201 are embedded in the four bearing holes 105 through bearings, and the two opposite moving blocks 202 form a group, and the surfaces on the tops of the two groups of moving blocks 202 are movably embedded in the two T-slots 103.

[0029] Specifically: the T-slot 103 is used to limit the movement of the moving block 202 to prevent the moving block 202 from rotating with the knob bidirectional screw rod 201 when the knob bidirectional screw rod 201 is rotated, thereby affecting the normal use of the device.

[0030] In one embodiment, the top of the electric cylinder 301 is fixedly connected to the bottom of one end of the n-type support frame 102 .

[0031] Specifically: it is used to fix one end of the electric cylinder 301. After the electric cylinder 301 is started, the electric cylinder 301 will extend to change the cutting depth of the cutting blade 306, thereby completing the cutting of the entire insulation pipe.

[0032] Working principle: The external controller is electrically connected to the electric cylinder 301 and the motor 305 and is controlled in association; the worker holds the two sides of the top of the n-shaped support frame 102, places the device on the top of the fixed insulation pipe, and places the insulation pipe between the two sets of moving blocks 202, and rotates the knob bidirectional screw rod 201 and the knob worm 207 according to the diameter of the insulation pipe. Since the moving blocks 202 are threadedly connected to the knob bidirectional screw rod 201, the moving blocks 202 on both sides will follow the rotation of the knob bidirectional screw rod 201 and approach each other, and the clamping claw 208 will rotate according to the knob worm 207, and the fixing column 208 will rotate around the fixing column 202. 203 changes the angle so that the clamping claw 208 fits the insulation pipe more closely, thereby achieving the purpose of preliminarily fixing the device. The device is then connected to an external power supply device, which provides power to the electric cylinder 301 and the motor 305. The worker holds both sides of the n-shaped support frame 102 and starts the electric cylinder 301 and the motor 305 through an external controller. The cutting blade 306 rotates following the output end of the motor 305 to cut the insulation pipe flat. The device can be fixed on the surface of insulation pipes with different diameters by designing it in this way, thereby improving the practicability of the device. At the same time, the device is small in size, convenient for hand-held work and more flexible.
