Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an assistive device for removing round pipes. Background Technology

[0002] In construction, old round pipes may need to be removed due to aging, damage, or design changes. After the old round pipes are removed, the site can be leveled to facilitate the installation of new pipes or facilities. At the same time, removing the old round pipes can prevent damage to existing pipes during the new construction process and prevent pollution of the construction environment caused by long-term corrosion and damage of the old round pipes, thereby reducing construction risks and potential safety hazards. The removed round pipes can also be recycled, reducing resource waste and saving on construction material costs. It is necessary to efficiently handle old round pipes inserted into the ground before construction.

[0003] In existing round pipe removal operations, workers usually remove the pipes by hand or saw off the protruding part of the pipe directly. This is too labor-intensive and inefficient. In addition, some round pipes are buried too deep in the ground or are corroded and rusted, making them difficult to remove by manpower alone, which poses a safety hazard. Forklifts, cranes, and wire ropes are also used to assist in removing round pipes, but this makes the operation more complicated and less efficient, and it is difficult to implement in relatively confined spaces. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an assistive device for removing round pipes. The operator changes the position of the pressure bar on the support rod according to the length of the round pipe protruding from the ground and the tightness of its insertion into the ground. After the hook is fastened to the round pipe, the support is horizontally supported on the ground. The operator presses down the handle, and the anti-slip structure connected to the inner side of the hook pulls the round pipe. Under the pulling force of the lever principle, the round pipe is pulled out. The removal of round pipes is simpler, faster, and more thorough, improving the recovery efficiency and quality of round pipes buried in the ground.

[0005] This utility model is achieved through the following technical solution:

[0006] An assistive device for removing round tubes includes a support, a support rod, and a pressure rod. The support rod has an H-shaped structure and is perpendicular to the top surface of the support, connected to the center of the top surface of the support. The pressure rod is rotatably connected to the upper inner side of the support rod. One end of the pressure rod is connected to a handle, and the other end is rotatably connected to a hook. The hook is connected to a rotating groove and a limiting groove. The rotating groove has a U-shaped structure, and the end of the pressure rod connected to the hook is rotatably connected to the inner side of the rotating groove.

[0007] Furthermore, the upper part of the support rod has multiple support rod adjustment holes that are equidistantly connected perpendicular to the rod body.

[0008] Furthermore, multiple pressure rod adjustment holes are equidistantly and vertically connected at a quarter position of the rod body near the hook on the pressure rod, and the diameter of the pressure rod adjustment holes is equal to the diameter of the support rod adjustment holes.

[0009] Furthermore, the limiting groove has a U-shaped structure, with the inner side of the limiting groove parallel to the inner bottom surface of the rotating groove, and the inner bottom surface of the limiting groove parallel to the inner side of the rotating groove.

[0010] Furthermore, the inner side of the limiting groove is connected to a cylindrical support wall. The inner diameter of the support wall is larger than the spacing between the inner sides of the limiting groove and smaller than the height of the inner sides of the limiting groove.

[0011] Furthermore, the central axis of the support wall is parallel to the inner bottom surface of the limiting groove, and is inclined at 15 degrees toward the direction of the rotating groove relative to the inner side surface of the limiting groove.

[0012] Furthermore, an anti-slip structure is connected to the support wall. The anti-slip structure is parallel to the plane where the side opening of the limiting groove is located, and the protrusion of the anti-slip structure gradually thickens as it approaches the side opening.

[0013] Compared with the prior art, this utility model has the following obvious advantages:

[0014] I. This utility model features multiple adjustment holes vertically connected to the upper half of the support rod and the quarter-length of the pressure rod near the hook. The operator can adjust the height of the connection point of the pressure rod on the support rod and the distance between the hook and the connection point according to the length of the round tube protruding from the ground and the tightness of the round tube inserted into the ground. This allows for changing the position of the hook's force on the round tube and the force applied to the round tube, adapting to different round tube conditions.

[0015] II. This utility model features a U-shaped rotating groove and a limiting groove connected to the hook. A cylindrical support wall is connected to the inner side of the limiting groove. When the operator hooks the hook onto the tube and uses the device to pull up the tube, the hook rotates as the operator presses down the lever. The support wall fits the tube body, so that the pulling force of the hook on the tube follows the direction of the tube body and increases the contact area, thereby increasing the force on the tube. This effectively improves the efficiency of pulling the tube, saves manpower, and prevents the tube from bending and being damaged, making it difficult to pull out.

[0016] Third, because the support wall of the hook limiting groove of this utility model is connected with an anti-slip structure, the support wall adheres to the tube body under the action of the operator's force, and the anti-slip structure also contacts the tube body, increasing the friction between the hook and the tube body, preventing the hook from sliding on the tube, reducing the loss of force applied to the tube, and improving the efficiency of removing the tube.

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides an assistive device for removing round tubes, including a support 1, a support rod 2, a pressure rod 3, a handle 4, and a hook 5. In this embodiment, the support rod 2 has an H-shaped structure and is vertically connected to the center of the top surface of the support 1. The upper half of the support rod 2 has multiple support rod adjustment holes 201 that are equidistantly connected perpendicularly to the rod body. The pressure rod 3 is rotatably connected to the upper inner side of the support rod 2. One end of the pressure rod 3 is connected to the handle 4, and the other end is rotatably connected to the hook 5. Multiple pressure rod adjustment holes 301 are equidistantly connected perpendicularly to the quarter-length of the rod body near the hook 5. The diameter of the pressure rod adjustment holes 301 is equal to the diameter of the support rod adjustment holes 201. The hook 5 is connected to a rotating groove 501 and a limiting groove 502.

[0023] The rotating groove 501 and the limiting groove 502 are U-shaped structures. The inner side of the limiting groove 502 is parallel to the inner bottom surface of the rotating groove 501. The inner bottom surface of the limiting groove 502 is parallel to the inner side of the rotating groove 501. The end of the pressure rod 3 connected to the hook 5 and the side of the rotating groove 501 are both connected to through holes. The through holes are connected by bolts to achieve a rotating connection. The inner side of the limiting groove 502 is connected to a cylindrical support wall 503. The inner diameter of the support wall 503 is larger than the spacing between the inner sides of the limiting groove 502 and smaller than the height of the inner side of the limiting groove 502. The central axis of the support wall 503 is parallel to the inner bottom surface of the limiting groove 502 and is inclined at 15 degrees towards the rotating groove 501 relative to the inner side of the limiting groove 502. The support wall 503 is connected to an anti-slip structure 504 that is parallel to the plane where the side opening of the limiting groove 502 is located. The protrusion of the anti-slip structure 504 gradually thickens as it approaches the side opening.

[0024] When using this invention, the operator first adjusts the device according to the state of the round tube inserted into the ground. If the part of the round tube protruding from the ground is short, the operator removes the connector between the support rod 2 and the pressure rod 3, vertically lowers the relative position of the pressure rod 3 on the support rod 2, aligns the pressure rod adjustment hole 301 on the pressure rod 3 with the support rod adjustment hole 201 slightly below the support rod 2, and then reinstalls the removed connector. If the ground where the round tube is inserted is relatively firm or the round tube is inserted too deeply into the ground, the operator removes the connector between the support rod 2 and the pressure rod 3, moves the position of the pressure rod 3 so that the pressure rod adjustment hole 301 closer to the hook 5 is aligned with the support rod adjustment hole 201, and then reinstalls the removed connector.

[0025] After adjusting the device's state, the operator aligns the opening of the limiting groove 502 with the round tube body, attaches the hook 5 to the round tube, adjusts the position of the hook 5 on the tube body, and then places the support 1 stably on the ground. The operator presses down the handle 4, and with the support of the support rod 2, the downward force applied by the operator to the handle 4 is transformed into a greater upward pulling force at the other end of the pressure rod 3. The end of the pressure rod 3 connected to the hook 5 is pulled upward, and the hook 5 moves upward under the pull of the pressure rod 3. The support wall 503 of the limiting groove 502 fits against the tube body, and the anti-slip structure connected to the support wall 503 rubs against the round tube body, causing the hook 5 to pull the round tube, and the round tube is pulled out under the pulling force of the hook 5.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
