DETAILED DESCRIPTION

[0034] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] Embodiment 1:

[0037] A sole wear detection device, such as Figures 1 to 10 As shown, it includes a base 1, the top outer wall of the base 1 is rotatably connected with a center rod 25, and the top of the center rod 25 is welded with a receiving plate 18, and the circumferential outer wall of the receiving plate 18 is fixed with a mounting ring 7 by screws, and the side wall of the mounting ring 7 is installed with multiple groups of protrusion components, the protrusion components include a connecting plate 10 and an elastic member, the connecting plate 10 is fixed to the side wall of the mounting ring 7 by screws, and the elastic member includes a slide bar 21 slidably connected to the bottom of the connecting plate 10 and a conical block 23 fixed to the bottom of the slide bar 21, a spring 22 is clamped between the bottom of the connecting plate 10 and the top of the conical block 23, and a lifting mechanism for driving the conical block 23 is installed on the top of the base 1, and a friction protrusion is installed on the top of the slide bar 21;

[0038] When it is necessary to test the wear resistance of the sole, multiple groups of protrusion components are provided, each of which is equipped with different types of friction protrusions, so that the friction of the shoe when walking under different road conditions can be simulated. In the initial state, when the lifting mechanism does not lift the bottom of the conical block 23, the friction protrusion is flush with the surface of the receiving plate 18 under the action of the rebound force of the spring 22. When it is necessary to use the friction protrusion to test the wear resistance of the sole, the conical block 23 is lifted by the lifting mechanism, so that the friction protrusion moves up along the receiving plate 18, and the wear resistance of the sole is tested when the sole and the friction protrusion rub against each other.

[0039] During the wear resistance test of the sole, rubber and other particles will be produced due to wear. By setting the friction protrusion to be able to rise and fall along the receiving plate 18, when the top of the friction protrusion is flush with the surface of the receiving plate 18, it is convenient to clean the rubber particles on the receiving plate 18, thereby preventing the friction protrusion from protruding from the surface of the receiving plate 18, making it difficult to clean and collect the rubber particles.

[0040] The friction protrusion comprises a friction block 1 26, a friction block 27, a friction block 3 28, a friction block 4 29 and a mounting plate 30, wherein the mounting plate 30 is welded to the top outer wall of the slide bar 21, and the friction block 1 26, the friction block 27, the friction block 3 28, and the friction block 4 29 are respectively fixed to their corresponding mounting plates 30 by embedding;

[0041] In this embodiment, the number of mounting plates 30 is preferably set to four groups, and friction block 1 26, friction block 27, friction block 3 28, and friction block 4 29 are respectively fixed on the four groups of mounting plates 30, so as to simulate the wear resistance test of the sole under different road conditions. In the actual testing process, the number of mounting plates 30 is not specifically limited.

[0042] The lifting mechanism includes a support seat 8 and a lifting block 20. The support seat 8 is welded to the top outer wall of the base 1 through a vertical rod 9, and the lifting block 20 is fixed to the top outer wall of the support seat 8 by screws, and both ends of the lifting block 20 are inclined structures;

[0043] By setting multiple groups of protrusion components to rotate around the central rod 25 as the axis, when the conical block 23 gradually approaches the lifting block 20 during the rotation, the inclined surfaces on both sides of the lifting block 20 guide the movement of the conical block 23. As the conical block 23 continues to move along the inclined surfaces, the lifting block 20 continuously lifts the conical block 23 upward, thereby causing the slide rod 21 to drive its corresponding friction protrusion to move upward.

[0044] The top outer wall of the base 1 is fixed with a support plate 2 by bolts, and the outer wall of one side of the support plate 2 is fixed with a drive motor 3 by bolts, and the output end of the drive motor 3 is connected with a rotating column 4 through a coupling, and a connecting block 11 is welded to the outer wall of the rotating column 4, and a mounting portion for fixing the shoes is installed at the bottom of the connecting block 11, and the mounting portion includes a sleeve 6 and a swing rod 33, the sleeve 6 is welded to the bottom of the connecting block 11, and the swing rod 33 is slidably connected to the inner wall of the through hole opened at the bottom of the sleeve 6, and a permanent magnet 36 is fixed to the top of the swing rod 33, and a spring 2 32 is clamped between the bottom of the permanent magnet 36 and the inner wall of the bottom of the sleeve 6, a pressure sensor 35 is fixed to the bottom of the swing rod 33 by screws, and an intermediate rod 34 is fixed to the bottom of the pressure sensor 35, and a sleeve plate 17 is installed at the bottom of the intermediate rod 34;

[0045] When the wear resistance of the sole is tested, the specifications and dimensions of the cover plate 17 are selected accordingly according to the size of the shoe to be tested. The cover plate 17 and the middle rod 34 can be fixed by screws. After the cover plate 17 is installed, the shoe is put on the cover plate 17, and the driving motor 3 is used to drive the shoe fixed on the mounting part to swing back and forth within a certain angle range. When the bottom of the sole moves to contact with the friction protrusion, the friction between the two is used to test the wear resistance of the sole, and the pressure sensor 35 can be used to monitor the pressure between the friction protrusion and the sole.

[0046] A horizontal plate 14 is welded to the inner wall of one side of the support plate 2, and a through hole opened on the surface of the horizontal plate 14 is rotatably connected to a driving column 15, and a bevel gear 13 is fixed to the top of the driving column 15 by a key, and a bevel gear 15 meshing with the bevel gear 13 is connected to the outer wall of the rotating column 4 by a key, a rotating frame 12 is welded to the outer wall of the driving column 15, and a T-shaped rod 39 is slidably connected to the through hole opened at one end of the rotating frame 12, and a spring 3 41 is clamped between the inner wall of one side of the T-shaped rod 39 and the rotating frame 12, and a pawl 40 is welded to one end of the T-shaped rod 39, and a ratchet 24 used in conjunction with the pawl 40 is fixed to the outer wall of the circumference of the center rod 25 by a pin;

[0047] By utilizing the transmission effect between bevel gear 1 5 and bevel gear 2 13, the driving motor 3 indirectly drives the rotating frame 12 and the pawl 40 to rotate with the center rod 25 as the axis. When the mounting portion rotates in the direction away from the protruding assembly, the pawl 40 drives the ratchet 24 to rotate forward during the synchronous rotation, switching the type of friction protrusion contacting the sole. When the mounting portion moves to the farthest distance and then rotates in the reverse direction, the pawl 40 rotates in the reverse direction along the ratchet 24. At this time, the friction force between the pawl 40 and the ratchet 24 is not enough to drive the ratchet 24 to rotate. When the mounting portion drives the shoe to move toward the friction protrusion, the relative stability of the friction protrusion is guaranteed.

[0048] The groove on the top of the lifting block 20 is embedded with an electromagnet 19, and the electromagnet 19 and the conical block 23 are used in conjunction with each other;

[0049] When the mounting part drives the friction between the sole and the friction protrusion, in order to prevent the sole from driving the protrusion assembly to move in the circumferential direction during this process, the electromagnet 19 is energized after the conical block 23 and the electromagnet 19 are docked, and the suction force of the electromagnet 19 on the conical block 23 is used to ensure the stability of the protrusion assembly, thereby preventing the protrusion assembly from moving during the detection process.

[0050] The inner wall of the top of the sleeve 6 is fixed with an electromagnet 31 by screws, and the electromagnet 31 and the permanent magnet 36 are used in coordination with each other;

[0051] In the process of testing the wear resistance of the sole, it is also necessary to consider the influence of the wearer's weight on its wear resistance. By setting the electromagnet 2 31 so that it can generate a repulsive force on the permanent magnet 36 after power is turned on, when the sole rotates to contact the friction protrusion, the magnetism of the electromagnet 2 31 is enhanced, and the greater the repulsive force on the permanent magnet 36, the pressure value monitored by the pressure sensor 35 will also increase synchronously. Therefore, by changing the repulsive force of the electromagnet 2 31 on the permanent magnet 36 after power is turned on, the wear resistance of the sole can be tested after wearers of different weights wear the shoes.

[0052] When the present embodiment is used, the specification of the cover plate 17 is first selected according to the shoe size of the detected shoe, and then the cover plate 17 and the middle rod 34 are fixed, and then the shoe is put on the cover plate 17 to complete the fixing of the shoe. In the initial stage, the whole device is in Figure 1 In the state shown, the sole and the friction protrusion are fitted with each other. During the detection, the driving motor 3 is used to drive the sleeve plate 17 and the shoe to rotate in the direction away from the friction protrusion. In this process, the transmission effect of the bevel gear 1 5 and the bevel gear 2 13 is used to make the pawl 40 drive the ratchet 24 to rotate forward. During the rotation, the ratchet 24 drives the friction protrusion fitted with the sole to rotate with the center rod 25 as the axis, so that the friction protrusion is in a dynamic environment. The friction force is applied to the sole. When the sole rotates to the process of disengaging from the friction protrusion, the center rod 25 realizes the position switching of different types of friction protrusions. When the position switching of the friction protrusion is completed, the shoe rotates to the maximum angle, and the electromagnet 19 is adsorbed and fixed to the conical block 23 corresponding to the friction protrusion after the position switching. Then the driving motor 3 is used to drive the sleeve plate 17 and the shoe to rotate in the opposite direction. When the sole moves to the surface of the friction protrusion after the switching, the friction protrusion is used to perform wear resistance detection on the sole.

[0053] According to the above detection method, multiple protrusion components are used to perform wear resistance detection on the soles in sequence. After a certain period of detection, the shoes are taken off, the thickness of the soles are measured and the degree of wear is detected, and the wear resistance of the soles is judged.

[0054] Embodiment 2:

[0055] A sole wear detection device, such as Figures 1 to 10 As shown, in order to facilitate the cleaning of rubber particles generated during the detection process, this embodiment makes the following supplements on the basis of embodiment 1: an embedded plate 38 is fixed to the top outer wall of the base 1 by bolts, and a dust suction pipe 16 is embedded on the surface of the embedded plate 38, and a dust suction cover 37 is fixed at one end of the dust suction pipe 16;

[0056] During the inspection, the end of the dust suction tube 16 away from the dust suction hood 37 is connected to the dust suction device. The dust suction device sucks the rubber particles on the surface of the containing plate 18 through the dust suction port opened on the dust suction hood 37, so as to ensure the cleanliness of the surface of the containing plate 18. After the jacking mechanism does not lift the conical block 23, the friction block 1 26, the friction block 27, the friction block 38, and the friction block 4 29 can be kept flush with the containing plate 18 under the action of the rebound force of the corresponding spring 22. Therefore, when the containing plate 18 rotates along the bottom of the dust suction hood 37, it is ensured that the dust suction hood 37 can completely suck in the rubber particles on the containing plate 18 to avoid cleaning dead corners.

[0057] The above is a preferred specific implementation manner of the present invention, and the protection scope of the present invention is not limited thereto. Any modification, equivalent substitution and improvement made by any technician familiar with the field within the technical scope disclosed by the present invention in combination with the prior art or public common sense, within the spirit and principle of the present invention, shall be covered by the protection scope of the present invention.
