[0001] The present invention relates to the technical field of pipe network removal, and in particular to an underground direct buried pipe network removal device for use in heating network reconstruction in old residential areas. Background Art

[0002] The main reason for the frequent accidents of road collapse, old and burst heating pipelines in old communities is the lack of basic information on underground pipelines. This has led to frequent excavation and repair of community roads, which has been figuratively likened to "road zippers", causing great inconvenience to residents' lives, especially when dealing with heating pipes and other pipelines buried deep underground. These facilities have increasingly suffered local damage due to the expiration of their service life and long-term environmental erosion.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0031] Example 1, reference Figure 1 to Figure 4 , which is the first embodiment of the present invention, and provides an underground direct buried pipe network dismantling device for the renovation of the heating network in old residential areas, including a pipe dismantling mechanism 100 including a support frame 101, a cutting slide 102 arranged on the support frame 101, an electric push rod 103 arranged on the cutting slide 102, and a cutting machine body 104 arranged on the electric push rod 103; and,

[0032] Among them, the support frame 101 is in a straight line shape, and the support frame 101 is used to accommodate the support mechanism 200, facilitate the storage of the support mechanism 200, and provide support for the cutting machine body 104. In this way, the cutting machine body 104 can be set up in narrow roads or places where large machinery is restricted from entering, which greatly reduces the intensity of manual work and improves the demolition efficiency.

[0033] Furthermore, the cutting slide 102 is slidably connected to the support frame 101. The cutting slide 102 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 pipeline, thereby facilitating the cutting work of the cutting machine body 104. The electric push rod 103 serves as a height adjustment power element for the cutting machine body 104, which can adjust the distance between the cutting machine body 104 and the pipeline, facilitating the cutting work of the cutting machine body 104 and improving the safety of pipeline dismantling.

[0034] The supporting mechanism 200 includes a supporting rod 201 disposed on the supporting frame 101 , a positioning assembly 202 disposed on the supporting rod 201 , a ground supporting assembly 203 disposed on the positioning assembly 202 , and a reinforcing assembly 204 disposed on the ground supporting assembly 203 .

[0035] Among them, there are two support rod bodies 201, which are respectively located at the two ends of the support frame 101. The support rod body 201 can be stored by flipping the support rod body 201 along the connection with the support frame 101. The positioning component 202 is located at the connection between the support rod body 201 and the support frame 101, and is used to reinforce the connection between the support frame 101 and the support rod body 201 when the support frame 101 is supporting work, to prevent the connection between the support rod body 201 and the support frame 101 from rotating due to uneven force, thereby affecting the supporting effect of the support frame 101. The ground support component 203 is located inside the support rod body 201, and is retractably arranged between the support rod body 201 and the support rod body 201, and is used to establish a connection between the support rod body 201 and the ground, increase the contact area between the support rod body 201 and the ground, and thereby improve the stability of the support rod body 201.

[0036] The locking assembly 202 includes a locking frame 202a arranged on the supporting frame body 101, a locking block 202b arranged on the locking frame 202a, a locking slot 202c arranged on the supporting rod body 201, and a releasing member 202d arranged on the locking frame 202a; the locking frame 202a and the supporting rod body 201 are rotatably connected, and the locking slot 202c and the locking block 202b are adapted to each other.

[0037] There are two positioning brackets 202a, which are respectively located on both sides of the lower end of the support frame 101. They are rotatably connected to the ends of the support rod 201. The support rod 201 can be stored by flipping the support rod 201 along the connection with the positioning bracket 202a, so that the support frame 101 can enter various places without being restricted by narrow roads. The positioning brackets 202b are symmetrically arranged on both sides of the positioning bracket 202a. There is a sliding connection between the positioning bracket 202a, and an elastic member is provided between the positioning block 202b and the positioning bracket 202a, so that the positioning block 202b can slide back and forth on the positioning bracket 202a. The positioning slot 202c is located on both sides of the end of the support rod body 201, and the positioning slot 202c is adapted to the positioning block 202b. By separating and combining the positioning block 202b and the positioning slot 202c, the support rod body 201 can be fixed and stored.

[0038] Furthermore, one end of the positioning block 202b that extends deep into the positioning slot 202c is in an oblique shape, with its concave end face facing the outside of the positioning frame 202a, and its convex end face facing the inside of the positioning frame 202a. When the support rod body 201 is flipped along the connection between the positioning frame 202a, its side surface preferentially contacts the concave end face of the positioning block 202b. As the flipping angle increases, it reaches the convex end face via the concave end portion, until after flipping to 90 degrees, the positioning block 202b is snapped into the positioning slot 202c. This design can increase the tightness of the connection between the positioning slot 202c and the positioning block 202b, and can also improve the snapping effect of the positioning block 202b.

[0039] The release member 202d includes a guide slide 202d-1 arranged on the positioning bracket 202a, a sliding slide 202d-2 arranged on the guide slide 202d-1, and a sliding slide 202d-3 arranged on the sliding slide 202d-2; the guide slide 202d-1 and the sliding slide 202d-2 are slidably connected; a telescopic protrusion 202d-4 is arranged at the end of the sliding slide 202d-3, and a telescopic groove 202d-5 is opened on the positioning block 202b; the telescopic groove 202d-5 is adapted to the telescopic protrusion 202d-4.

[0040] Among them, the guide slide bar 202d-1 is located on the side of the positioning card frame 202a, and the positioning card frame 202a and the guide slide bar 202d-1 are fixedly connected. The guide slide bar 202d-1 is used to provide guidance for the sliding of the sliding slide 202d-2. The sliding slide 202d-2 is located on the guide slide bar 202d-1. The sliding slide 202d-2 and the guide slide bar 202d-1 are slidably connected, and an elastic member is arranged between the sliding slide 202d-2 and the guide slide bar 202d-1 for pushing the sliding slide 202d-2 to reset. The number of sliding slide bars 202d-3 is two and they are symmetrically arranged. The sliding slide bar 202d-3 and the sliding slide 202d-2 are fixedly connected.

[0041] Furthermore, the telescopic protrusion 202d-4 is located at the end of the sliding slide rod 202d-3, and the telescopic protrusion 202d-4 is fixedly connected to the sliding slide rod 202d-3. The cross-section of the telescopic protrusion 202d-4 is a right-angled trapezoid, and its triangular end extends into the telescopic slide groove 202d-5. The telescopic slide groove 202d-5 is opened and then the positioning block 202b is engaged. The telescopic protrusion 202d-4 extends into the telescopic slide groove 202d-5, thereby promoting the positioning block 202b to slide on the positioning frame 202a, so that the positioning block 202b is separated from the positioning slot 202c, thereby realizing the storage of the support rod body 201.

[0042] Operation process: When it is necessary to dismantle the pipeline, first move the folded support frame 101 to a suitable position, flip the two support rods 201 to the working state along the connection with the support frame 101, so that the positioning slot 202c is aligned with the positioning block 202b, and the positioning block 202b is automatically inserted into the slot. According to the position of the pipeline, adjust the height of the electric push rod 103 to ensure that the cutting machine body 104 maintains an appropriate distance from the pipeline, adjust the cutting slide 102, so that the cutting machine body 104 is aligned with the pipeline position to be cut, and start the cutting machine body. The cutting machine body 104 is used for cutting. 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 pipe can be completely cut. After the cutting is completed, the cutting machine body 104 is closed, and the sliding slide bar 202d-3 is pulled to make the telescopic protrusion 202d-4 slide along the telescopic slide groove 202d-5, prompting the locking block 202b to withdraw from the locking groove 202c, and the support rod body 201 is flipped over and retracted to both sides of the support frame body 101 for storage. After the storage is completed, the entire device can be moved to the next work location by hand.

[0043] Example 2, reference Figure 5 and Figure 6 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and the difference is that: the ground supporting assembly 203 includes a ground supporting main rod 203a arranged in the supporting rod body 201, a supporting slide groove 203b opened on the supporting rod body 201, a limiting piece 203c arranged on the ground supporting main rod 203a, and a cleaning piece 203d arranged on the supporting rod body 201.

[0044] Among them, the main ground-supporting rod 203a is located inside the supporting slot 203b, and the main ground-supporting rod 203a and the supporting slot 203b are slidably connected. The supporting slot 203b serves as a receiving slot for the main ground-supporting rod 203a, which can protect the main ground-supporting rod 203a when not in use, and prevent the wear of the main ground-supporting rod 203a caused by the external environment. The limiting member 203c is located at the lower end of the inner part of the supporting slot 203b, and is used to fix and limit the main ground-supporting rod 203a after extension. The cleaning member 203d supports the lower end of the slot 203b, and is used to clean the main ground-supporting rod 203a, so as to keep the main ground-supporting rod 203a clean and tidy, thereby facilitating the storage and subsequent use of the main ground-supporting rod 203a.

[0045] Furthermore, the lower end of the main ground-supporting pole 203a is in the shape of an inverted flat-topped cone. The actual construction sites for pipeline dismantling are mostly muddy dirt roads. The flat-topped cone design can reduce the contact area between the main ground-supporting pole 203a and the ground, allowing the main ground-supporting pole 203a to be inserted into the soil more quickly, thereby facilitating the establishment of a connection between the main ground-supporting pole 203a and the ground, so that the main ground-supporting pole 203a can be quickly fixed.

[0046] The limiting member 203c includes a limiting protrusion 203c-1 arranged on the supporting main rod 203a, a limiting block 203c-2 arranged in the supporting slide groove 203b, and a limiting groove 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 slide groove 203b, and the limiting groove 203c-3 and the limiting protrusion 203c-1 are adapted to each other. The limiting member 203c also includes a pushing rod 203c-4 arranged on the supporting rod body 201, a pushing block 203c-5 arranged on the pushing rod 203c-4, and magnetic blocks 203c-6 are 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 rod 203c-4 and the pushing block 203c-5 are slidably connected.

[0047] Among them, the limiting protrusion 203c-1 is located on both sides of the upper end of the supporting main rod 203a, the limiting protrusion 203c-1 and the supporting main rod 203a are fixedly connected, the limiting block 203c-2 is located at the lower end of the supporting slide 203b, the limiting block 203c-2 and the supporting slide 203b are rotatably connected, a torsion spring is provided at the connection between the limiting block 203c-2 and the supporting slide 203b, and there is a certain angle between the limiting block 203c-2 and the supporting slide 203b, along the sliding direction of the supporting main rod 203a, the supporting main rod 203a is fixedly connected to the supporting main rod 203a, and the limiting block 203c-2 is fixedly connected to the supporting main rod 203a. The outer surface of the rod 203a can squeeze the limit block 203c-2, so that the limit block 203c-2 is close to the side wall of the support slide groove 203b, until the limit protrusion 203c-1 passes through the limit slot 203c-3, and the limit block 203c-2 is clamped on the limit protrusion 203c-1. A triangle is formed between the limit protrusion 203c-1, the limit block 203c-2 and the inner wall of the support slide groove 203b. When the cutting machine body 104 is installed, the upper end of the support frame 101 is squeezed into a triangular shape by gravity, thereby achieving a stable effect.

[0048] Specifically, there are two pushing rods 203c-4, the pushing rod 203c-4 is fixedly connected to the supporting rod body 201, and the pushing block 203c-5 is slidably connected to the pushing rod 203c-4. By sliding up the pushing block 203c-5, the two magnetic blocks 203c-6 are close to and attracted to each other, so that the limiting block 203c-2 fits the inner wall of the supporting groove 203b, thereby facilitating the main supporting rod 203a to retract into the supporting groove 203b.

[0049] The rest of the structure is the same as that of Example 1.

[0050] Operation process: After using the support frame 101 for supporting work, first ensure that the positioning block 202b has been inserted into the positioning slot 202c to stabilize the support rod body 201, and then extend the supporting main rod 203a from the supporting slot 203b, and the lower end of the supporting main rod 203a slides downward, so that the supporting main rod 203a squeezes the limiting block 203c-2 to make it temporarily close to the side wall of the supporting slot 203b. However, when the fiber protrusion reaches the limiting slot 203c-3 position, the limiting block 203c-2 naturally pops out due to the action of the torsion spring, and the limiting protrusion 203c-1 is clamped to fix the supporting main rod 203a, and then the supporting main rod 203a is moved to the ground. Ensure that the device is stable, adjust the position of the cutting machine body 104, and start cutting. After the support work is completed, slide and push the card block 203c-5 to make the magnetic block 203c-6 attract each other. The limit card block 203c-2 is close to the inner wall of the support slide groove 203b due to the action of the magnetic block 203c-6, and is separated from the limit protrusion 203c-1, and the main support rod 203a is retracted into the support slide groove 203b. During the storage process, use the cleaning piece 203d to clean the main support rod 203a to keep it clean and tidy, so as to realize the storage of the support rod body 201 and the support frame body 101, and then complete the storage of all components for the subsequent use of the device.

[0051] Example 3, reference Fig. 9 , which is the third embodiment of the present invention. This embodiment 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 supporting rod body 201, a cleaning swivel 203d-2 arranged on the cleaning ring frame 203d-1, and a cleaning brush 203d-3 arranged on the inner wall of the cleaning swivel 203d-2; the cleaning ring frame 203d-1 and the cleaning swivel 203d-2 are rotatably connected, and the cleaning swivel 203d-2 is adapted to the supporting rod body 201.

[0052] Among them, the cleaning ring frame 203d-1 is located at the lower end of the supporting rod body 201, the cleaning ring frame 203d-1 and the supporting rod body 201 are fixedly connected, the cleaning swivel 203d-2 and the cleaning ring frame 203d-1 are rotatably connected, and the cleaning swivel 203d-2 is adapted to the main ground supporting rod 203a. The main ground supporting rod 203a slides up and down through the cleaning swivel 203d-2, so that the cleaning swivel 203d-2 can remove impurities and dirt on the surface of the main ground supporting rod 203a, thereby ensuring that the main ground supporting rod 203a is clean and tidy, so as to facilitate the storage and preservation of the main ground supporting rod 203a.

[0053] Specifically, the cleaning brushes 203d-3 on the inner wall of the cleaning ring frame 203d-1 are arranged in a spiral shape. This arrangement allows the cleaning brushes 203d-3 to drive the cleaning swivel 203d-2 to rotate when the main support rod 203a passes through the cleaning brushes 203d-3, thereby improving the cleaning effect of the cleaning swivel 203d-2.

[0054] The rest of the structure is the same as that of Example 2.

[0055] Operation process: When storing the main ground supporting rod 203a, the main ground supporting rod 203a starts to slide upward, and when passing through the cleaning swivel 203d-2, the cleaning brush 203d-3 starts to rotate and clean the dirt and impurities on the main ground supporting rod 203a. The spiral arrangement of the cleaning brush 203d-3 helps to better remove the attachments. The main ground supporting rod 203a is completely retracted into the supporting slide groove 203b, completing the storage and protection of the main ground supporting rod 203a.

[0056] Example 4, reference Figures 1 to 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the reinforcement component 204 includes a reinforcement rod body 204a arranged on both sides of the ground-supporting main rod 203a, an insertion plug plate 204b arranged on the reinforcement rod body 204a, and an insertion pin 204c arranged on the insertion plug plate 204b; the reinforcement rod body 204a and the ground-supporting main rod 203a are rotatably connected, and the insertion plug plate 204b and the reinforcement rod body 204a are rotatably connected; the reinforcement component 204 also includes a reinforcement clamping ring 204d arranged on the ground-supporting main rod 203a; the reinforcement clamping ring 204d is adapted to the reinforcement rod body 204a.

[0057] Among them, the reinforcing rod body 204a and the ground-supporting main rod 203a are rotatably connected, and the expansion angle between the reinforcing rod body 204a and the ground-supporting main rod 203a is between 30 and 90 degrees. The lower end of the reinforcing rod body 204a is rotatably connected with an insertion plate 204b, and the insertion plate 204b is used to increase the contact area between the reinforcing rod body 204a and the ground, thereby providing a supporting effect for the ground-supporting main rod 203a. The insertion pin 204c is located on the insertion plate 204b, which is used to increase the stability of the reinforcing rod body 204a and the ground. The reinforcing clamp 204d is located on the ground-supporting main rod 203a, which is adapted to the reinforcing rod body 204a and is used to store the reinforcing rod body 204a.

[0058] Specifically, the reinforcing rod body 204a is unfolded to form a triangle between the reinforcing rod body 204a, the main ground-supporting rod 203a and the ground. The insertion plate 204b can rotate relative to the reinforcing rod body 204a to adapt to different ground conditions. The end of the insertion pin 204c is usually set to a sharp shape to facilitate easier insertion into the soil.

[0059] The rest of the structure is the same as that of Example 3.

[0060] Operation process: When the main ground-supporting rod 203a is performing supporting work, the reinforcing rod body 204a is rotated outward from both sides of the ground-supporting rod 203a to the required angle, and the insertion plate 204b is pressed downward to make it perpendicular or nearly perpendicular to the ground, and the insertion nail 204c is inserted into the ground to ensure that the reinforcing rod body 204a is stable, so that the main ground-supporting rod 203a can be more stable, and then the insertion nail 204c is pulled out, the insertion plate 204b is retracted, the reinforcing rod body 204a is fixed on the reinforcing clamp 204d, and the main ground-supporting rod 203a is retracted.
