[0053] Embodiment 1

[0054] See Figures 3 to 9 , the present invention provides an anchor net side grinding device, which includes a bottom table 1, a main support assembly 2 and a grinding assembly 3;

[0055] The main support assembly 2 is rotationally and horizontally slidably connected to the tabletop of the bottom table 1, and the main support assembly 2 forms the positioning and support for the anchor net 100 from bottom to top;

[0056] The grinding assembly 3 is located on one side of the bottom table 1, and the grinding assembly 3 horizontally slides along the edge direction of the bottom table 1. The grinding assembly 3 includes a cylindrical grinding roller 31, the long axis of the grinding roller 31 is parallel to the tabletop of the bottom table 1, and the height of the grinding roller 31 in the vertical direction can be adjusted.

[0057] The grinding assembly 3 further includes a main track 32 provided on one side of the bottom table 1, and the long axis of the main track 32 is parallel to the tabletop of the bottom table 1;

[0058] A carrier vehicle 33 is slidably connected to the main track 32, and the grinding roller 31 is provided on the carrier vehicle 33.

[0059] A secondary support assembly 4 is provided between the main track 32 and the tabletop of the bottom table 1;

[0060] The main support assembly 2 provides a supporting force to the middle part of the anchor net 100, and the secondary support assembly 4 provides a supporting force to the edge of the anchor net near the grinding assembly 3;

[0061] Moreover, the supporting force provided by the secondary support assembly 4 to the edge of the anchor net 100 is opposite to the layer being ground by the grinding assembly 3. Since the anchor net 100 is mostly composed of two layers of welded iron wires, when the grinding assembly 3 grinds the end of the upper layer of iron wires of the anchor net 100, the grinding assembly 3 will exert a downward pressure on the edge of the anchor net 100. At this time, the secondary support assembly 4 provides a supporting force from bottom to top to the edge of the anchor net 100. On the contrary, when the grinding assembly 3 grinds the lower layer of the anchor net 100, the secondary support assembly 4 needs to provide a supporting force from top to bottom to the edge of the anchor net 100, or rather, the secondary support assembly 4 plays a certain limiting role on the edge of the anchor net 100.

[0062] A chute 11 is provided on the tabletop of the base 1, and the long-axis extension line of the chute 11 is perpendicular to the long axis of the main track 32. The main support assembly 2 slides along the chute 11;

[0063] The main support assembly 2 includes a long strip-shaped main support plate 21. A slider 22 is rotatably connected to the lower side of the main support plate 21, and a lead screw 23 is rotatably provided on the lower side of the tabletop of the base 1. The slider 22 is threadedly connected to the lead screw 23.

[0064] The lead screw 23 is driven to rotate by a lead screw motor 24, and the lead screw motor 24 and the lead screw 23 are driven by a sprocket and chain combination. Through the lead screw structure, it is convenient to ensure the distance between the edge of the anchor net 100 to be ground and the main track 32, facilitating the operation of the grinding roller 31.

[0065] A number of positioning columns 211 are fixedly provided on the upper side of the main support plate 21, and the positioning columns 211 are evenly distributed in a linear array along the long axis of the main support plate 21;

[0066] The outer diameter of the positioning column 211 is smaller than the width of the middle mesh hole of the anchor net 100;

[0067] A number of slots 212 are provided on the plate body of the main support plate 21. The slots 212 are long slots and are parallelly distributed on both sides of the positioning column 211;

[0068] Insert blocks 213 are correspondingly provided for the slots 212;

[0069] The insert block 213 includes a top plate with a through hole. The through hole on the top plate corresponds to the positioning column 211. Two parallel vertical plates are provided on the lower side of the top plate, and the distance between the outer sides of the two vertical plates and the width of the vertical plates correspond to the length and width of the mesh hole of the anchor net 100.

[0070] When the main support plate 21 is in use, first, the anchor net 100 is sleeved on the main support plate 21, making the main support plate 21 generally located in the middle of the anchor net 100. To facilitate the sleeving of the main support plate 21 and the anchor net 100, the outer diameter of the positioning post 211 can be set smaller. After sleeving, the insertion block 213 is inserted into the slot 212. Different insertion blocks 213 can be made according to the anchor nets 100 with different specifications of mesh holes, making the vertical plate of the insertion block 213 closely combine with the mesh holes. At the same time, the positioning post 211 at the position of the insertion block 213 is inserted into the through hole on the top plate of the insertion block 213, thus completing the connection between the anchor net 100 and the main support plate 21.

[0071] A rotating shaft is provided on the lower side of the plate body of the main support plate 21, and the main support plate 21 is rotatably connected to the slider 22 through the rotating shaft.

[0072] A rotating shaft motor for driving the rotating shaft to rotate is provided inside the slider 22.

[0073] Since the four edges of the anchor net 100 need to be polished, the main support plate 21 can be driven to rotate either electrically or manually, and the anchor net 100 is rotated by rotating the main support plate 21.

[0074] The carrier vehicle 33 includes a roller group 331 slidably connected to the main track 32. A rotating rod 332 is fixedly provided on the upper side of the roller group 331, and the lower side of the frame 333 of the carrier vehicle 33 is rotatably connected to the rotating rod 332;

[0075] A polishing roller 31 is rotatably connected to one side of the frame 333 facing the base 1. A polishing motor 34 is also provided on the frame 333. The motor shaft of the polishing motor 34 is linked with the polishing roller 31, and the polishing motor 34 drives the polishing roller 31 through a sprocket and chain combination.

[0076] A handle 35 is provided on one side of the frame 333 away from the base 1.

[0077] On the one hand, the staff can pull the carrier vehicle 33 along the main track 32 through the handle 35, thereby realizing the overall polishing of one side edge of the anchor net 100. On the other hand, the staff can adjust the polishing force by raising and lowering the handle. In addition, since the polishing roller 31 is located above and below the anchor net 100 for polishing according to the actual polishing situation, it is easier to adjust through the handle 35.

[0078] Embodiment 2

[0079] See Figure 10 and Figure 11 Based on Embodiment 1, a pulling component 334 is provided on one side of the frame 333. The pulling component 334 includes a hanging plate 3341 fixedly connected to the frame 333;

[0080] One end of the hook plate 3341 is connected to the vehicle frame 333, and the other end extends to the lower side of the main track 32. The hook plate 3341 is connected to the pull plate 3342, and the pull plate 3342 can be located below the main track 32 and rotate horizontally;

[0081] One end of the hanging plate 3341 located at the lower side of the main track 32 is rotatably connected to one end of the pulling plate 3342, and the other end of the pulling plate 3342 is connected to the tension spring 3343;

[0082] A pull rod corresponding to the tension spring 3343 is respectively disposed on one side of the frame 333 facing the base 1 and the other side away from the base 1 .

[0083] One end of the tension spring 3343 is an annular body, which is rotatably connected to the pull plate 3342, and the other end is provided with a hook, which is hung with the pull rod through the hook. When it is necessary to grind the upper edge of the anchor net 100, the pull plate 3342 is rotated to the side close to the base 1, and the tension spring 3343 is hung on the side of the frame 333 facing the base 1, so that the grinding roller 31 is pulled downward to facilitate its contact with the anchor net 100, thereby ensuring a good grinding effect and reducing the burden of the staff on the frame 333. On the contrary, when it is necessary to grind the lower edge of the anchor net 100, the hook of the tension spring 3343 is removed, the pull plate 3342 is rotated to the other side, and then the tension spring 3343 is hung on the pull rod on the side of the handle 35 of the frame 333. Under the pulling of the tension spring 3342, the grinding roller 31 is tilted upward, so that the grinding of the lower edge of the anchor net 100 can have a good labor-saving effect.

[0084] Example 3

[0085] On the basis of the above embodiment, the auxiliary support assembly 4 includes a horizontal plate 41 connected to the base 1, the horizontal plate 41 extends toward one side of the main rail 32, and at least two horizontal plates 41 are provided;

[0086] Each horizontal plate 41 has a vertical through hole, into which a limiting screw 42 is inserted, and two positioning nuts are threadedly connected on the body of the screw 42, and the positioning nuts are respectively located on the upper and lower sides of the horizontal plate 41;

[0087] All the limiting screws 42 are threadedly connected to the horizontally arranged limiting plates 43 .

[0088] The screw rod 42 may be inserted into the mesh of the anchor net 100 .

[0089] The limiting screw 42 can be adjusted to a suitable extension height by two positioning nuts. If the upper edge of the anchor net 100 is to be polished, the limiting plate 43 is placed on the lower side of the anchor net 100 to lift the edge of the anchor net 100 from the lower side, so as to facilitate the application of force during polishing. On the contrary, when the lower edge of the anchor net 100 is to be polished, the limiting plate 43 is placed on the upper side of the anchor net 100.

[0090] On one side of the bottom base 1, a horizontal track support plate 36 is fixedly arranged. The track support plate 36 is connected to the main track 32 through a number of ejector rods 37, and the ejector rods 37 are telescopic rods.

[0091] The ejector rods 37 can be selected from telescopic rods such as electric, pneumatic, and hydraulic ones. Considering that the grinding roller 31 needs to be adjusted in horizontal height according to the grinding position, the additional structure of the ejector rods 37 can be used more conveniently and flexibly.

[0092] On one side of the main track 32, a secondary track 321 is arranged. The hanging plate 3341 passes through the secondary track 321 and is fixedly connected to the vehicle frame 333. The part of the hanging plate 3341 located inside the secondary track 321 is sleeved with small rollers, and the small rollers are slidably connected to the secondary track 321.

[0093] Through the structure of the secondary track 321, a support point for the hanging plate 3341 is formed to ensure smooth movement when the mobile carrier vehicle 33 is moving.

[0094] The carrier vehicle 33 of this solution can also be selected to be electrically driven. By driving the wheels of the carrier vehicle 33 to reciprocate along the main track 32, semi-automatic grinding can be achieved. It only requires the staff to adjust the grinding roller 31 to grind the upper edge or the lower edge of the anchor net 100 according to the situation.

[0095] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
