DETAILED DESCRIPTION

[0042] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0043] This embodiment provides a technical solution: a wear resistance detection device for a belt conveyor, such as Figure 1 As shown, the device comprises a friction mechanism 5, a clamping mechanism, a frosting particle discharge mechanism 4 and a cleaning mechanism 7 integrated on a base 1. The base 1 is provided to connect the device as an integrated unit. A collection box 2 is provided on the lower side of the clamping mechanism. The collection box 2 can be removed and is used to load used frosting particles to prevent the frosting particles from splashing and ensure the cleanliness of the surrounding environment of the device.

[0044] like Figure 7 As shown, the friction mechanism 5 includes an annular friction element and a driving member for driving the annular friction element to rotate circumferentially; the driving member includes a bracket seat 52 rotatably mounted through two support plates 51, a first motor 53 for driving the bracket seat 52 to rotate is fixed on one of the support plates 51, a cylinder 54 is fixed on the outer side of the bracket seat 52, and the annular friction element is mounted on the outer circumferential surface of the cylinder 54. When the first motor 53 is running, the annular friction element can be driven to rotate, and the annular friction element fits with the belt 8, so that the belt 8 can be tested for wear resistance.

[0045] Further, such as Figure 7As shown, the annular friction element includes a plurality of arc-shaped friction plates 55, and the plurality of arc-shaped friction plates 55 are annularly distributed on the outer circumferential surface of the cylinder 54, thereby forming an annular structure. The outer circumferential surface of the arc-shaped friction plate 55 is provided with a plurality of triangular arc-shaped grooves distributed along its axial direction. The triangular arc-shaped grooves are evenly distributed and cover the outer circumferential surface of the arc-shaped friction plate 55. The setting of the triangular arc-shaped grooves can fit the abrasive particles, thereby preventing the abrasive particles from moving and detaching from the arc-shaped friction plate 55 during detection or preventing the abrasive particles from being too concentrated, thereby ensuring the detection effect.

[0046] Further, such as Figure 7 As shown, at least one T-shaped block 56 is fixed to the inner circumference of the arc-shaped friction plate 55, and a T-shaped block 56 adapted to the T-shaped block 56 is provided on the outer circumference of the cylinder 54. Bolts screwed to the T-shaped block 56 are provided on the inner circumference of the cylinder 54. During installation, the T-shaped block 56 is inserted into the T-shaped groove 57, and then the cylinder 54 and the T-shaped block 56 are connected and fixed by bolts, and the arc-shaped friction plate 55 is fixed on the cylinder 54, so that the arc-shaped friction plate 55 can be easily replaced and maintained.

[0047] Further, such as Figure 1 As shown, in order to make the installation of the belt 8 more convenient, the position of the friction mechanism 5 can be moved laterally, and a lateral displacement mechanism 6 is set on the base 1 to realize that the friction mechanism 5 is away from or close to the belt 8. The lateral displacement mechanism 6 is used to control the displacement of the friction mechanism 5 between the working station and the waiting working station. When installing the belt 8, the friction mechanism 5 is switched to the waiting working station through the lateral displacement mechanism 6, and the belt 8 can be installed on the clamping mechanism. The lateral displacement mechanism 6 includes a bottom plate slidably installed by a first slide rail slider structure, and the first slide rail slider structure is installed on the base 1. The bottom plate is driven to slide by a first telescopic pole. By extending the first telescopic pole, the lateral position of the friction mechanism 5 can be adjusted.

[0048] Further, such as Figure 1 As shown, in order to allow the annular friction element of the friction mechanism 5 to be displaced along its axial direction and realize the transverse wear resistance detection of the belt 8, a reciprocating mechanism 9 is arranged on the bottom plate, and the reciprocating mechanism 9 is used to reciprocate the friction mechanism 5 along its axial direction to realize the transverse friction of the belt 8. The reciprocating mechanism 9 includes a moving plate slidably mounted on the bottom plate through a second slide rail slider structure, and a second telescopic pole driving the moving plate to reciprocate is fixed on the bottom plate. The friction mechanism 5 is arranged on the moving plate, that is, by reciprocatingly extending and contracting the second telescopic pole, the annular friction element can be reciprocated longitudinally displaced to realize the wear resistance detection of the belt 8, that is, another dimension of detection method is provided, which increases the applicability of the device.

[0049] like Figure 1 and Figure 2As shown, the clamping mechanism is arranged on one side of the friction mechanism 5, which is used to fix and tighten the belt 8 to fit the outer surface of the annular friction element when the friction mechanism 5 is located at the working station; the clamping mechanism includes two symmetrically arranged mounting vertical plates, the mounting vertical plates are installed on the base 1, and there are two vertically symmetrically arranged clamping members 31 between the two mounting vertical plates, and the two mounting vertical plates are each provided with a pushing member 32, the pushing member 32 is used to drive the two clamping members to operate and tighten the belt, and the pushing member 32 is located between the two clamping members 31.

[0050] like Figures 1 to 6 As shown, the clamping member 31 includes a first clamping block 311 vertically slidably mounted on the mounting vertical plate and a second clamping block 312 slidably mounted on the mounting vertical plate along a folding line track; at least two bent holes 313 are provided on the mounting vertical plate, and the bent holes 313 include an inclined portion and a vertical portion connected to the inclined portion to ensure the stability of the second clamping block 312 during movement, and the inclined portion of the bent hole 313 is located on the side of the vertical portion close to the pusher 32, and the inclined portion extends and tilts toward the side away from the first clamping block 311. A crossbar penetrating the bent hole 313 is fixed to the side wall of the second clamping block 312, and a guide wheel 314 arranged in the bent hole 313 is rotatably mounted on the crossbar. The number of crossbars and guide wheels 314 corresponds to the number of bent holes 313, and the guide wheel 314 is adapted to the width of the bent hole 313, and the guide wheel 314 slides along the bent hole 313 to achieve the sliding of the second clamping block 312 along the folding line track.

[0051] like Figures 1 to 6 As shown, elastic structures are installed on the mounting vertical plate to drive the second clamping block 312 and the first clamping block 311 to move toward the side of the inclined portion, that is, the elastic structure of the upper clamping member 31 will pull the second clamping block 312 and the first clamping block 311 downward, while the elastic structure of the lower clamping member 31 will pull the second clamping block 312 and the first clamping block 311 upward. Therefore, when not subject to other forces, the first clamping block 311 and the second clamping block 312 are both located at the extreme position on the side of the bending hole 313 close to the pushing member 32; the first clamping block 311 and the second clamping block 312 are close to each other on one side with concave and convex parts, and the setting of the concave and convex parts can make the belt 8 have a bending structure when clamped to increase the stability of clamping the belt 8. At the same time, when the second clamping block 312 is pushed to move in the vertical portion, the first clamping block 311 will also move accordingly.

[0052] like Figure 4 and Figure 6As shown, in other embodiments, in order to make the lateral position of the first clamping block 311 adjustable, a lifting plate 3110 is vertically slidably installed between the two mounting vertical plates, specifically: vertical sliding holes 317 are opened on the two mounting vertical plates, and sliders 318 are slidably installed in the two vertical sliding holes 317, and the two ends of the lifting plate 3110 are respectively fixedly connected to the two sliders 318, and the first clamping block 311 has no direct connection with the two mounting vertical plates, and a plum screw 316 threadedly connected to the lifting plate 3110 is rotatably installed on the first clamping block 311, and an optical axis sliding through the lifting plate 3110 is fixed on the first clamping block 311, that is, by twisting the plum screw 316, the smooth lateral displacement of the first clamping block 311 can be ensured, and the lateral position of the first clamping block 311 can be adjusted to adapt to the clamping of belts 8 of different thicknesses.

[0053] like Figure 4 and Figure 6 As shown, the elastic structures acting on the second clamping block 312 and the first clamping block 311 are respectively the first elastic rope 315 and the second elastic rope 319, the two ends of the first elastic rope 315 are respectively fixedly connected to the extension plate 325 and the mounting vertical plate, and the two ends of the second elastic rope 319 are respectively fixedly connected to the slider 318 and the mounting vertical plate.

[0054] like Figures 2 to 4 As shown, the pushing member 32 includes two vertical sliding bars 321 slidably mounted on the mounting vertical plate, and a rack 323 is fixed to one end of the two vertical sliding bars 321 close to each other. The two racks 323 are meshed and connected with a gear 324, and the gear 324 is located between the two racks 323. The gear 324 is driven to rotate by a third motor 322. The third motor 322 is fixed to the mounting vertical plate through a mounting seat. When the third motor 322 is running, the gear 324 can be driven to rotate, and further, through cooperation with the two racks 323, the two vertical sliding bars 321 are driven to move in opposite directions.

[0055] like Figures 2 to 4 As shown, the ends of the two vertical sliding rods 321 that are away from each other are fixed with a stop plate 326, and the outer end of the cross bar is fixed with an extension plate 325 through a connecting plate. The extension plate 325 is fixed to all the cross bars to ensure stability. The stop plate 326 is connected to the extension plate 325. The stop plate 326 and the extension plate 325 have a certain size in the horizontal direction to ensure that the two can always remain connected. In order to reduce the friction between the two, a plurality of balls 327 are embedded and rotatably installed on one side of the stop plate 326 close to the extension plate 325. The balls 327 can also be replaced by rollers.

[0056] The process of clamping the belt 8 by the clamping mechanism is as follows: first, the friction mechanism 5 is moved to the working position by the lateral displacement mechanism 6, and the two abutment plates 326 are made close to each other by running the third motor 322. At this time, the second clamping block 312 and the first clamping block 311 of the two clamping members 31 will be located at the extreme position close to the pushing member 32 by the elastic structure, and there will be a certain gap between the second clamping block 312 and the first clamping block 311. The lower end of the belt 8 is passed through the gap between the second clamping block 312 and the first clamping block 311 of the upper clamping member 31, and finally extends to the gap between the second clamping block 312 and the first clamping block 311 of the lower clamping member 31, and then the friction mechanism 5 is moved to the working position by the lateral displacement mechanism 6. At this time, one side of the annular friction element of the friction mechanism 5 exceeds the connecting line between the two clamping members 31 (such as Fig.10 As shown), the third motor 322 is operated to make the two abutment plates 326 move away from each other, further pushing the two second clamping blocks 312 away from each other, and due to the guidance of the bent hole 313, the second clamping block 312 will gradually approach one side of the first clamping block 311 until the guide wheel 314 enters the vertical part of the bent hole 313, at which time the belt 8 is clamped and fixed by the second clamping block 312 and the second clamping block 312, and the friction mechanism 5 can be operated to perform wear resistance detection on the belt 8; if it is necessary to tighten the belt 8, the third motor 322 can be continued to be operated to make the second clamping blocks 312 of the upper and lower clamping members 31 move along the vertical part of the bent hole 313, and the second clamping block 312 and the first clamping block 311 will move synchronously along the vertical part of the bent hole 313, that is, the belt 8 is tightened, and the force of the belt 8 acting on the surface of the annular friction element of the friction mechanism 5 can be adjusted, thereby adjusting the pressure environment during detection.

[0057] like Figure 1 , Figure 8 and Fig. 9 As shown, the frosted particle discharge mechanism 4 is arranged on the upper side of the friction mechanism 5, and is used to add frosted particles between the annular friction element and the belt 8 to adjust the roughness of the wear resistance test of the annular friction element. The frosted particle discharge mechanism 4 includes an elongated shell 42 fixed to the support plate 51 of the friction mechanism 5 through a support plate 41, and the elongated shell 42 has a plurality of storage cavities 43, and the plurality of storage cavities 43 are arranged side by side, and the plurality of storage cavities 43 store frosted particles of different specifications, and the lower side of the elongated shell 42 has a guide cover 44 connected to the plurality of storage cavities 43, and the guide cover 44 faces one side of the belt 8, and a material discharge piece is arranged in the guide cover 44, and the material discharge piece is used to discharge the frosted particles in the corresponding storage cavity 43.

[0058] like Figure 8 and Fig. 9As shown, the discharge member includes a rotating rod 452 rotatably mounted inside the guide cover 44, and a discharge through hole 453 is provided on the rotating rod 452 along its axial direction, and the length of the discharge through hole 453 is equal to the length of the storage cavity 43. A second motor 451 that drives the rotating rod 452 to rotate is fixed to the outside of the elongated shell 42, and a plurality of storage cavities 43 are formed in the elongated shell 42 by a plurality of partitions, and the lower ends of the plurality of partitions all have a widening portion, the bottom of the widening portion contacts the surface of the rotating rod 452, and the width of the widening portion is greater than the width of the discharge through hole 453, and the discharge through hole 453 is adjusted by the second motor 451 to dock with the corresponding storage cavity 43 to discharge the corresponding frosted particles, and when one end of the rotating rod 452 corresponds to the widening portion, the discharge of the frosted particles is closed, and when one end of the rotating rod 452 corresponds to part of the widening portion, a small amount of frosted particles can be discharged, thereby accurately controlling the discharge amount of the frosted particles.

[0059] like Figure 5 and Figure 7 As shown, the cleaning mechanism 7 includes an elongated guide tube 71 and an elongated air nozzle 72. The elongated air nozzle 72 is connected to an external air compressor. The air flow direction blown out by the elongated air nozzle 72 is toward the lower surface of the annular friction element and rebounds into the elongated guide tube 71, and is guided into the collection box 2 through the elongated guide tube 71. During operation, after the frosted particles pass between the belt 8 and the annular friction element, a portion of the frosted particles will directly fall into the collection box 2. Since the upper end of the elongated guide tube 71 is close to the surface of the annular friction element, a portion of the frosted particles will contact the elongated guide tube 71 and be guided to the collection box 2 through the elongated guide tube 71. The frosted particles or dust remaining on the surface of the annular friction element will eventually be blown into the elongated air nozzle 72 by the airflow ejected from the elongated air nozzle 72, and finally enter the collection box 2. It should be noted that: since the outer surface of the annular friction element has a curvature, the airflow trajectory ejected from the elongated air nozzle 72 will not flow into the gap between the elongated guide tube 71 and the annular friction element.

[0060] When the present invention is in use, the belt 8 is first fixed by the clamping mechanism and the friction mechanism 5 is moved to the working station, and then the frosted particles are discharged by the frosted particle discharge mechanism 4. The annular friction element can be driven to rotate by the first motor 53, and the rotation direction is that the upper end of the annular friction element rotates toward one side of the belt 8, so that rotational friction detection can be realized; the annular friction element can also be driven to move laterally by the reciprocating mechanism 9, so as to realize transverse friction detection. In this mode, the circumferential position of the annular friction element can be adjusted by the first motor 53 to avoid the accumulation of frosted particles, that is, multiple modes of wear resistance detection of the belt 8 can be realized.

[0061] The above are only preferred embodiments of the present invention, which are only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims, but all of them will fall within the scope of protection of the present invention.
