Detailed implementation manners

[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Please refer to Figures 1 to 11 together, and now an auxiliary support device for a wall-climbing skin scraping device provided by the present invention will be described. The auxiliary support device for a wall-climbing skin scraping device is arranged on the main body structure 1 of the wall-climbing skin scraping device. A scraping knife 2 is provided at the bottom of the main body structure 1. The auxiliary support device includes two support seats 3 and a fixing mechanism; the two support seats 3 are slidably arranged at the bottom of the main body structure 1; the two support seats 3 are respectively located on both sides of the scraping knife 2; a support component 31 is provided on each support seat 3, and the support component 31 is used to contact the outer peripheral wall of the plastic pipe; the fixing mechanism is arranged on the support seat 3; the fixing mechanism is used to fix the support seat 3 and the main body structure 1 so that the support seat 3 is fixed on the main body structure 1.

[0038] An auxiliary support device for a wall-climbing scraping device provided by the present utility model, compared with the prior art, by adjusting the position of the support base 3, the support members 31 on the two support bases 3 can be brought into contact with the outer peripheral wall of the plastic pipe, thereby playing a supporting role for the main body structure 1. During the process of the scraping knife 2 removing the scale on the outer peripheral wall of the plastic pipe, the situation of the main body structure 1 and the scraping knife 2 swinging can be reduced, facilitating the scraping knife 2 to scrape the scale on the outer peripheral wall of the pipe.

[0039] In some embodiments, as Figures 1 to 11 shown, the bottom of the main body structure 1 has an arc surface, and the support base 3 has the freedom to slide along the arc surface; the side of the main body structure 1 has an arc groove 11 coaxially arranged with the arc surface, and both sides of the support base 3 are bent and located at the position of the arc groove 11; the bent part of the support base 3 has a connecting column 32 that slidably cooperates with the arc groove 11, and the outer peripheral wall of the connecting column 32 contacts the two side walls of the arc groove 11.

[0040] It should be noted that the support base 3 slides along the direction of the arc groove, which can adjust the position of the support base 3 in the circumferential direction, so that the support member 31 contacts the outer peripheral wall of the plastic pipe, which can play a supporting role for the main body structure 1; during the process of scraping the scale of the plastic pipe, the swing of the main body structure 1 can be avoided. The support base 3 is slidably matched with the arc groove 11 through the connecting column 32, which can limit the sliding direction of the support base 3 and can also perform lateral limitation on the support base 3.

[0041] In some embodiments, as Figures 1 to 11 shown, the support base 3 has a protrusion 33, the support member 31 is a plate-like structure, and the support members 31 on the two support bases 3 are respectively a first hinge plate 311 and a second hinge plate 312; the rotating shafts of the first hinge plate 311 and the second hinge plate 312 are rotatably matched with the corresponding protrusions 33; a positioning structure is provided on the support base 3 for fixing the position of the hinge plate; a number of positioning holes 313 are provided around the hinge axis of the first hinge plate 311 and the second hinge plate 312, and the protrusion 33 has a through hole aligned with one of the positioning holes 313; the positioning structure includes a positioning shaft 34, and the positioning shaft 34 is inserted and matched with the through hole on the protrusion 33 and the positioning hole 313 to position the angle of the hinge plate.

[0042] It should be noted that when adjusting the angles of the first hinge plate 311 and the second hinge plate 312, the positioning shaft 34 is separated from the positioning holes 313 on the first hinge plate 311 and the second hinge plate 312; after the first hinge plate 311 and the second hinge plate 312 are rotated to the specified positions, the positioning shaft 34 is inserted and matched with the positioning holes 313 to fix the positions of the first hinge plate 311 and the second hinge plate 312.

[0043] In some embodiments, asFigures 1 to 11 As shown, the supporting member 31 is a supporting roller 314, and the supporting roller 314 is rotatably arranged on the supporting seat 3.

[0044] It should be noted that when the supporting member 31 is the supporting roller 314, the supporting roller 314 contacts the outer peripheral wall of the plastic pipe. When the main structure 1 rotates circumferentially around the plastic pipe, the supporting roller 314 rotates in cooperation with the plastic pipe, which can reduce the friction between the supporting member 31 and the plastic pipe.

[0045] In some embodiments, as Figures 1 to 11 shown, the auxiliary supporting device further includes a driving mechanism 4. The driving mechanism 4 is arranged on one side of the main structure 1. The driving mechanism 4 includes a first arc-shaped rack 41 and a second arc-shaped rack 42; the first arc-shaped rack 41 is coaxially arranged with the arc-shaped groove 11; the first arc-shaped rack 41 is connected to one of the supporting seats 3; the second arc-shaped rack 42 is coaxially arranged with the arc-shaped groove 11; the second arc-shaped rack 42 is connected to the other supporting seat 3; wherein, the radius of the first arc-shaped rack 41 is greater than the radius of the second arc-shaped rack 42, the teeth of the first arc-shaped rack 41 are located on the inner side, and the teeth of the second arc-shaped rack 42 are located on the outer side; the driving mechanism 4 further includes a gear 43 rotatably arranged on the main structure 1, and the gear 43 meshes with the first arc-shaped rack 41 and the second arc-shaped rack 42 at the same time; the fixing mechanism is used to connect the gear 43 and the main structure 1 to fix the sliding position of the supporting seat 3.

[0046] It should be noted that by rotating the gear 43, the first arc-shaped rack 41 and the second arc-shaped rack 42 can be rotated circumferentially, thereby driving the two supporting seats 3 to approach or separate from each other; therefore, the positions of the two supporting seats 3 can be adjusted simultaneously. After the adjustment of the two supporting seats 3 is in place, by fixing the positions of the gear 43 and the main structure 1 through the fixing mechanism, the adjusted positions of the supporting seats 3 can be fixed.

[0047] In some embodiments, as Figures 1 to 11 shown, a positioning disk 44 is fixedly arranged on the rotating shaft of the gear 43, and the diameter of the positioning disk 44 is greater than the diameter of the rotating shaft of the gear 43; the main structure 1 has a positioning groove that rotates in cooperation with the positioning disk 44.

[0048] It should be noted that by arranging the positioning disk 44 on the rotating shaft of the gear 43 and through the cooperation between the positioning disk 44 and the positioning groove, the gear 43 can be laterally limited, so that the gear 43 rotates in place on the main structure 1.

[0049] In some embodiments, as Figures 1 to 11As shown in the figure, the fixing mechanism includes a connecting rod 5, which is arranged on the gear 43 and is eccentrically arranged with the gear 43; the gear 43 has a threaded hole, and the connecting rod 5 has an external thread; the main body structure 1 has a fixing hole that is inserted and matched with the connecting rod 5.

[0050] It should be noted that by arranging the connecting rod 5 on the gear 43, the operator can rotate the gear 43 by grasping the connecting rod 5; after the gear 43 rotates to the in-place position, rotate the connecting rod 5 so that the end of the connecting rod 5 is inserted and matched with the fixing hole of the main body structure 1, thereby fixing the position of the gear 43; after the position of the gear 43 is fixed, the positions of the two support seats 3 are also fixed accordingly.

[0051] In some embodiments, as Figures 1 to 11 shown, both the first arc-shaped rack 41 and the second arc-shaped rack 42 are connected to the outside of the support seat 3.

[0052] It should be noted that since both the first arc-shaped rack 41 and the second arc-shaped rack 42 are located outside the support seat 3, when adjusting the positions of the two support seats 3, the arc-shaped rack on one of the support seats 3 can cross over the other support seat 3, improving the adjustment stroke.

[0053] In some embodiments, as Figures 1 to 11 shown, the fixing mechanism includes a fixing bolt 6, and the support seat 3 has a threaded hole that is threadedly matched with the fixing bolt 6; the threaded end of the fixing bolt 6 is used to abut against the main body structure 1.

[0054] It should be noted that when the two support seats 3 slide horizontally, by abutting the threaded end of the fixing bolt 6 against the main body structure 1, the position of the support seat 3 can be fixed.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
