[0022] In an embodiment, the cutting slide plate 102 is in sliding connection with the support frame body 101, and is used to drive the cutting machine body 104 to move in parallel, so that the cutting machine body 104 can be adjusted in parallel according to the position of the pipe, thereby facilitating the cutting work of the cutting machine body 104. The electric push rod 103 serves as a height adjusting power element of the cutting machine body 104, and can adjust the distance between the cutting machine body 104 and the pipe, thereby facilitating the cutting work of the cutting machine body 104.

[0023] The supporting mechanism 200 includes a support rod body 201 arranged on the support frame body 101, a clamping assembly 202 arranged on the support rod body 201, a ground supporting assembly 203 arranged on the clamping assembly 202, and a reinforcing assembly 204 arranged on the ground supporting assembly 203.

[0024] The number of the support rod bodies 201 is two, which are respectively located at two ends of the support frame body 101, and the support rod bodies 201 can be stored by being turned along the connection with the support frame body 101, the clamping component 202 is located at the connection between the support rod body 201 and the support frame body 101, and is used for reinforcing the connection between the support frame body 101 and the support rod body 201 when the support frame body 101 supports, so as to prevent the connection between the support rod body 201 and the support frame body 101 from being turned due to uneven force, and affect the supporting effect of the support frame body 101, the ground supporting component 203 is located in the inside of the support rod body 201, and is telescopically arranged between the support rod body 201, and is used for establishing the connection between the support rod body 201 and the ground, increasing the contact area between the support rod body 201 and the ground, and then improving the stability of the support rod body 201.

[0025] The clamping component 202 comprises a clamping frame 202a arranged on the support frame body 101, a clamping block 202b arranged on the clamping frame 202a, a clamping slot 202c arranged on the support rod body 201, and a releasing component 202d arranged on the clamping frame 202a, the clamping frame 202a is rotationally connected with the support rod body 201, and the clamping slot 202c is matched with the clamping block 202b.

[0026] The number of the clamping frames 202a is two, which are respectively located at two sides of the lower end of the support frame body 101, and are rotationally connected with the end portions of the support rod body 201, the support rod body 201 can be stored by being turned along the connection with the clamping frame 202a, so as to conveniently make the support frame body 101 enter various places without being limited by narrow roads, the clamping blocks 202b are symmetrically arranged at two sides of the clamping frame 202a, are slidingly connected with the clamping frame 202a, and are provided with elastic components between the clamping blocks 202b and the clamping frame 202a, so as to make the clamping blocks 202b reciprocally slide on the clamping frame 202a, the clamping slots 202c are located at two sides of the end portions of the support rod body 201, are matched with the clamping blocks 202b, and can fix and store the support rod body 201 by being combined and separated with the clamping blocks 202b.

[0027] Further, the end of the clamping block 202b that is inserted into the clamping slot 202c is beveled, the concave end of the clamping block 202b faces the outer side of the clamping frame 202a, and the convex end of the clamping block 202b faces the inner side of the clamping frame 202a. When the support rod body 201 is flipped along the connection between the clamping frame 202a, the side of the clamping block 202b first contacts the concave end of the clamping block 202b, and then the convex end of the clamping block 202b is contacted as the flipping angle increases. When the flipping angle reaches 90 degrees, the clamping block 202b is clamped into the clamping slot 202c. This design can increase the tightness of the connection between the clamping slot 202c and the clamping block 202b, and improve the clamping effect of the clamping block 202b.

[0028] The release member 202d includes a guide slide rod 202d-1 arranged on the clamping frame 202a, a sliding carriage 202d-2 arranged on the guide slide rod 202d-1, and a sliding slide rod 202d-3 arranged on the sliding carriage 202d-2. The guide slide rod 202d-1 and the sliding carriage 202d-2 are connected in a sliding manner. The sliding slide rod 202d-3 is provided with an extension protrusion 202d-4 at the end, and the clamping block 202b is provided with an extension slot 202d-5. The extension slot 202d-5 and the extension protrusion 202d-4 are matched.

[0029] The guide slide rod 202d-1 is arranged on the side of the clamping frame 202a, and the clamping frame 202a and the guide slide rod 202d-1 are fixedly connected. The guide slide rod 202d-1 is used to guide the sliding of the sliding carriage 202d-2. The sliding carriage 202d-2 is arranged on the guide slide rod 202d-1, and the sliding carriage 202d-2 and the guide slide rod 202d-1 are connected in a sliding manner. An elastic member is arranged between the sliding carriage 202d-2 and the guide slide rod 202d-1, and is used to push the sliding carriage 202d-2 to reset. The number of sliding slide rods 202d-3 is two, and the sliding slide rods 202d-3 are symmetrically arranged. The sliding slide rods 202d-3 and the sliding carriage 202d-2 are fixedly connected.

[0030] Further, the extension protrusion 202d-4 is arranged at the end of the sliding slide rod 202d-3, and the extension protrusion 202d-4 and the sliding slide rod 202d-3 are fixedly connected. The cross section of the extension protrusion 202d-4 is in the shape of a right trapezoid, the triangular end of the extension protrusion 202d-4 is inserted into the extension slot 202d-5, and the extension slot 202d-5 is arranged on the clamping block 202b. The extension protrusion 202d-4 is inserted into the extension slot 202d-5, thereby promoting the sliding of the clamping block 202b on the clamping frame 202a, separating the clamping block 202b from the clamping slot 202c, and achieving the storage of the support rod body 201.

[0031] Operation process: when the pipeline needs to be removed, first, the folded support frame body 101 is transported to the appropriate position, and the two support rod bodies 201 are turned to the working state along the connection with the support frame body 101, so that the clamping groove 202c is aligned with the clamping block 202b, the clamping block 202b is automatically clamped into the clamping groove, according to the position of the pipeline, the height of the electric push rod 103 is adjusted to ensure that the cutting machine body 104 maintains a proper distance from the pipeline, the cutting slide 102 is adjusted so that the cutting machine body 104 is aligned with the position of the pipeline that needs to be cut, and the cutting machine body 104 is started to cut. During the cutting process, the position of the cutting machine body 104 can be adjusted by sliding the cutting slide 102 to ensure that the entire pipeline can be completely cut. After cutting, the cutting machine body 104 is turned off, the sliding slide 202d-3 is pulled to make the telescopic protrusion 202d-4 slide along the telescopic slide groove 202d-5, and the clamping block 202b is pulled out of the clamping groove 202c. Turn the support rod body 201 back to the support frame body 101 on both sides to achieve storage. After storage is completed, the entire device can be manually moved to the next work site.

[0032] Embodiment 2, referring to Figures 5 and 6, is the second embodiment of the present application, which is based on the previous embodiment, except that the ground supporting assembly 203 includes a ground supporting main rod 203a arranged in the support rod body 201, a support slide groove 203b opened on the support rod body 201, a limiting piece 203c arranged on the ground supporting main rod 203a, and a cleaning piece 203d arranged on the support rod body 201.

[0033] The ground supporting main rod 203a is located inside the support slide groove 203b, and the ground supporting main rod 203a and the support slide groove 203b are connected by sliding. The support slide groove 203b serves as a container for the ground supporting main rod 203a, which can protect the ground supporting main rod 203a when it is not in use, preventing external environments from causing wear and tear to the ground supporting main rod 203a. The limiting piece 203c is located at the lower end of the support slide groove 203b and is used to fix and limit the extended ground supporting main rod 203a. The cleaning piece 203d is located at the lower end of the support slide groove 203b and is used to clean the ground supporting main rod 203a, keeping it clean and tidy, thereby facilitating the storage and subsequent use of the ground supporting main rod 203a.

[0034] Further, the lower end of the ground supporting main rod 203a is in the shape of an inverted flat-topped cone. The actual construction site of pipeline removal is often a muddy and rough dirt road. The design of a flat-topped cone can reduce the contact area between the ground supporting main rod 203a and the ground, allowing the ground supporting main rod 203a to be inserted into the soil more quickly, thereby facilitating the connection between the ground supporting main rod 203a and the ground, allowing the ground supporting main rod 203a to be quickly fixed.

[0035] The limiting piece 203c comprises a limiting protrusion 203c-1 arranged on the ground supporting main rod 203a, a limiting block 203c-2 arranged in the supporting sliding groove 203b, and a limiting slot 203c-3 arranged on the limiting block 203c-2; a torsion spring is arranged between the limiting block 203c-2 and the inner wall of the supporting sliding groove 203b, the limiting slot 203c-3 is matched with the limiting protrusion 203c-1, the limiting piece 203c further comprises a pushing block 203c-4 arranged on the supporting rod body 201, a pushing block 203c-5 arranged on the pushing block 203c-4, and a magnetic block 203c-6 arranged on the pushing block 203c-5 and the limiting block 203c-2; the magnetic blocks 203c-6 are attracted to each other, and the pushing block 203c-4 and the pushing block 203c-5 are in sliding connection.

[0036] The limiting protrusion 203c-1 is arranged on both sides of the upper end of the ground supporting main rod 203a, and the limiting protrusion 203c-1 is in fixed connection with the ground supporting main rod 203a; the limiting block 203c-2 is arranged at the lower end of the supporting sliding groove 203b, and the limiting block 203c-2 is in rotational connection with the supporting sliding groove 203b; a torsion spring is arranged at the connecting position of the limiting block 203c-2 and the supporting sliding groove 203b, and the limiting block 203c-2 and the supporting sliding groove 203b have a certain included angle; along the sliding direction of the ground supporting main rod 203a, the outer surface of the ground supporting main rod 203a can extrude the limiting block 203c-2, so that the limiting block 203c-2 is close to the side wall of the supporting sliding groove 203b, until the limiting protrusion 203c-1 passes through the limiting slot 203c-3, the limiting block 203c-2 is clamped on the limiting protrusion 203c-1, and the limiting protrusion 203c-1, the limiting block 203c-2 and the inner wall of the supporting sliding groove 203b form a triangle; after the cutting machine body 104 is installed, the upper end of the supporting frame body 101 is extruded by gravity to form a triangle, thereby achieving a stable effect.

[0037] Specifically, the number of the pushing blocks 203c-4 is two, the pushing blocks 203c-4 are in fixed connection with the supporting rod body 201, and the pushing block 203c-5 is in sliding connection with the pushing block 203c-4; by sliding the pushing block 203c-5 upwards, the two magnetic blocks 203c-6 are attracted to each other, so that the limiting block 203c-2 is close to the inner wall of the supporting sliding groove 203b, thereby facilitating the contraction of the ground supporting main rod 203a into the supporting sliding groove 203b.

[0038] The remaining structures are the same as those in Embodiment 1.

[0039] The operation process is as follows: when the support frame body 101 is used for supporting work, first of all, it is ensured that the clamping block 202b has been clamped into the clamping slot 202c of the support rod body 201 to be stable, then the ground supporting main rod 203a is stretched out from the support sliding groove 203b, the lower end of the ground supporting main rod 203a is slid downward, so that the ground supporting main rod 203a extrudes the limiting clamping block 203c-2 to temporarily adhere to the side wall of the support sliding groove 203b, but when the fiber protrusion reaches the limiting clamping slot 203c-3 position, the limiting clamping block 203c-2 is naturally popped out due to the action of the torsional spring, clamping the limiting protrusion 203c-1 to fix the ground supporting main rod 203a, and then the ground supporting main rod 203a is placed on the ground to ensure that the device is stable, the position of the cutting machine body 104 is adjusted, the cutting action is started, after the supporting work is completed, the magnetic block 203c-6 is attracted to each other by sliding the clamping block 203c-5, the limiting clamping block 203c-2 adheres to the inner wall of the support sliding groove 203b due to the action of the magnetic block 203c-6, and the limiting protrusion 203c-1 is separated, the ground supporting main rod 203a is retracted into the support sliding groove 203b, and in the storage process, the cleaning member 203d is used to clean the ground supporting main rod 203a to keep it clean and tidy, and the storage of the support rod body 201 and the support frame body 101 is realized, and then the storage of all parts is completed, so as to facilitate the subsequent use of the device.

[0040] In example 3, referring to FIG. 9, the third embodiment of the present application is different from the second embodiment in that the cleaning member 203d includes a cleaning ring frame 203d-1 arranged at the lower end of the support rod body 201, a cleaning rotating ring 203d-2 arranged on the cleaning ring frame 203d-1, and a cleaning brush 203d-3 arranged on the inner wall of the cleaning rotating ring 203d-2; the cleaning ring frame 203d-1 and the cleaning rotating ring 203d-2 are rotationally connected, and the cleaning rotating ring 203d-2 is adapted to the support rod body 201.

[0041] The cleaning ring frame 203d-1 is located at the lower end of the support rod body 201, the cleaning ring frame 203d-1 and the support rod body 201 are fixedly connected, the cleaning rotating ring 203d-2 and the cleaning ring frame 203d-1 are rotationally connected, and the cleaning rotating ring 203d-2 is adapted to the ground supporting main rod 203a. Through the process of sliding the ground supporting main rod 203a up and down, the cleaning rotating ring 203d-2 can clean the impurities and soil on the surface of the ground supporting main rod 203a, so as to ensure the cleanliness of the ground supporting main rod 203a and facilitate the storage and preservation of the ground supporting main rod 203a.

[0042] Specifically, the cleaning brushes 203d-3 arranged in a spiral manner on the inner wall of the cleaning ring 203d-1 are configured to rotate the cleaning rotating ring 203d-2 when the ground supporting main rod 203a passes through the cleaning brushes 203d-3, thereby improving the cleaning effect of the cleaning rotating ring 203d-2.

[0043] The remaining structures are the same as those in Embodiment 2.

[0044] Operation process: when the ground supporting main rod 203a is stored, the ground supporting main rod 203a starts to slide upward, and when the ground supporting main rod 203a passes through the cleaning rotating ring 203d-2, the cleaning brushes 203d-3 start to rotate and clean the soil and impurities on the ground supporting main rod 203a. The spiral arrangement of the cleaning brushes 203d-3 helps to better remove the attached objects. The ground supporting main rod 203a is completely retracted into the supporting sliding groove 203b, and the storage and protection of the ground supporting main rod 203a are completed.

[0045] Embodiment 4, referring to FIGS. 1-9, is a third embodiment of the present application. The difference between this embodiment and the second embodiment is that the reinforcing assembly 204 includes reinforcing rod bodies 204a arranged on both sides of the ground supporting main rod 203a, insertion plates 204b arranged on the reinforcing rod bodies 204a, and insertion nails 204c arranged on the insertion plates 204b.

[0046] The reinforcing rod bodies 204a are rotationally connected with the ground supporting main rod 203a, and the angle between the reinforcing rod bodies 204a and the ground supporting main rod 203a is between 30-90°. The insertion plates 204b are rotationally connected to the lower ends of the reinforcing rod bodies 204a. The insertion plates 204b are used to increase the contact area between the reinforcing rod bodies 204a and the ground, thereby providing support for the ground supporting main rod 203a. The insertion nails 204c are arranged on the insertion plates 204b and are used to increase the stability of the reinforcing rod bodies 204a and the ground. The reinforcing clamps 204d are arranged on the ground supporting main rod 203a and are adapted to the reinforcing rod bodies 204a, thereby storing the reinforcing rod bodies 204a.

[0047] Specifically, the reinforcing rod bodies 204a form a triangle with the ground supporting main rod 203a and the ground. The insertion plates 204b can rotate relative to the reinforcing rod bodies 204a to adapt to different ground conditions. The insertion nails 204c are usually arranged in a sharp shape to facilitate easier insertion into the soil.

[0048] The remaining structures are the same as those in Embodiment 3.

[0049] Operation process: when the ground supporting main rod 203a is supporting, rotate the reinforcing rod body 204a outward from both sides of the ground supporting main rod 203a to the required angle, press down the inserted plug plate 204b to make it perpendicular or close to perpendicular to the ground, insert the inserted plug 204c into the ground, ensure the stability of the reinforcing rod body 204a, so that the ground supporting main rod 203a can be more stable, then pull out the inserted plug 204c, retract the inserted plug plate 204b, fix the reinforcing rod body 204a on the reinforcing clasp 204d, and retract the ground supporting main rod 203a.

[0050] Furthermore, in order to provide a concise description of the exemplary embodiments, not all features of actual implementations can be described (i.e., those features not relevant to the presently considered implementation of the best mode of the application, or those features not relevant to the implementation of the application).
