[0001] The invention relates to the technical field of ice surface processing, and in particular to an ice surface smoothing device with a blade anti-loosening function. Background Art

[0002] When conducting cold-weather test at winter test sites in extremely cold regions, the test will cause friction scratches on the highly flat ice road, resulting in poor flatness of the ice surface and affecting the deviation of the test data. In order to obtain scientific and accurate test data, the ice surface is usually ground and polished using grinding equipment.

[0003] When the grinding device is grinding and polishing the ice surface, a high-speed rotating mounting plate usually carries multiple grinding heads to process the ice surface. In order to facilitate the replacement of the grinding heads, the installation between the grinding heads and the mounting plate is mostly achieved through screw and nut fixings. In the process of the grinding heads grinding and polishing the ice surface, the screws and nuts may rotate due to the force generated in the process, thereby causing the connection between the grinding heads and the mounting plate to loosen. Summary of the invention

A circular opening for the rotating rod to pass through is provided in the middle of the movable plate. The lower surface of the movable plate is circularly fixed with a plurality of pairs of rubber inserts with convex cross sections, and the middle portion of the rubber inserts is made of a hard material. A socket with a convex cross section is symmetrically and vertically provided on the top of the screw rod, and a rotation-limiting space for vertically inserting the rubber insert is formed between the socket mouth wall and the inner wall of the locking nut, and the plurality of pairs of rubber inserts correspond to the positions of the plurality of through grooves respectively.

[0006] As a preferred solution, a positioning rod is symmetrically fixedly mounted on the top of the grinding head, and a plurality of pairs of positioning grooves for inserting the positioning rods are provided in a circular shape on the lower surface of the mounting plate.

[0007] As a preferred solution, an axle is horizontally rotatably mounted on the bottom of the machine body, two wheels are fixedly sleeved on the axle, and a driving motor for providing rotational driving force to the rotating rod is fixedly mounted on the upper surface of the machine body.

[0008] As a preferred solution, a plurality of mounting grooves are provided on the upper surface of the mounting plate, and the plurality of mounting grooves are respectively located on one side of the plurality of through-openings, a hollow tube is horizontally fixedly installed in the mounting groove, an insertion rod is horizontally slidably inserted in the hollow tube, a telescopic spring is provided in the hollow tube, an L-shaped moving rod is fixedly installed on the upper surface of one end of the insertion rod located outside the hollow tube, a non-slip layer of rubber material is bonded to the surface of the moving rod, and the plurality of through-openings are respectively located on the moving paths of the plurality of moving rods.

[0009] As a preferred solution, a through opening is opened in the wall of the installation groove, and the multiple through openings are respectively connected with the multiple through openings. A rotating shaft is horizontally rotatably installed in the installation groove, one end of the rotating shaft passes through the through opening and enters the through opening, and a magnetic block is fixedly installed on one end of the rotating shaft located in the through opening, a first gear is fixedly sleeved on the rotating shaft, and a first rack rod meshingly connected to the first gear is fixedly installed on one end of the insertion rod.

[0010] As a preferred solution, a rotating hole is vertically opened in the installation groove, a straight rod is vertically rotatably installed in the rotating hole, the straight rod passes through the bottom end of the installation plate and is fixedly sleeved with a connecting rod, a baffle is fixedly installed at one end of the connecting rod, the multiple through grooves are respectively located on the rotation paths of the multiple baffles, and the rotation of the straight rod is controlled by a transmission assembly.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. After the grinding cutter head is installed on the mounting plate through the cooperation between the screw rod and the locking nut, the movable plate can be controlled to move downward, so that multiple rubber inserts are vertically inserted into the restricted space between the socket and the locking nut, thereby limiting the rotation of the screw rod and the locking nut, avoiding looseness of the connection between the grinding cutter head and the mounting plate, and improving the tightness of the installation of the grinding cutter head; 2. Through the cooperation between the positioning rod and the positioning slot, when the screw rod passes through the slot, the two sockets at the top will correspond to the positions of a pair of rubber inserts respectively, without spending time to align the positions between the sockets and the rubber inserts; 3. When the mounting plate rotates at high speed, the multiple rods will move away from the hollow tube due to the centrifugal force. The anti-skid layers bonded to the surfaces of some moving rods will press against the surfaces of multiple locking nuts, thereby pressing the locking nuts and preventing the locking nuts from rotating, thus further improving the tightness of the installed grinding head. 4. When the plug rod is moved in a direction away from the hollow tube by the effect of centrifugal force, the first rack rod will also move, and the first gear meshing with the first rack rod will rotate with the rotating shaft. When the plug rod moves to the point where the moving rod fixedly connected to its end is tightly against the locking nut, the plug rod can no longer move under the effect of centrifugal force, and the magnetic block at the end of the rotating shaft will also flip to the position corresponding to the lower position of the locking nut, thereby generating magnetic attraction to the locking nut, thereby enhancing the effect of limiting the self-rotation of the locking nut. 5. When the inserted rod in the installation groove on the side of the through-hole where the screw is not installed moves in the direction away from the hollow tube under the action of centrifugal force, the moving rod will not be blocked by the locking nut, and thus will move the second rack rod to the farthest point, and the second gear meshing with the second rack rod will rotate with the straight rod and the baffle, and the baffle will rotate to cover the through-hole where the screw is not installed, so as to avoid some broken ice or ice chips hitting the through-hole where the screw is not installed during the grinding and polishing of the ice surface, thereby causing the through-hole to deform and the screw cannot pass through normally afterwards.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] Reference Figure 1-Figure 11 , an ice surface grinding device with a blade anti-loosening function, comprises a body 1 and a plurality of grinding blades 2, a rotating rod 3 is vertically rotatably mounted on the lower surface of the body 1, a mounting plate 4 is fixedly mounted on the bottom of the rotating rod 3, a screw 5 is fixedly mounted on the upper surface of the grinding blade 2, a locking nut 6 is threadedly sleeved on the screw 5, a plurality of through grooves 7 for the screw 5 to enter are provided on the lower surface of the mounting plate 4, a circular through hole 26 is provided at the bottom of the through groove 7, and the diameter of the through hole 26 is smaller than the diameter of the locking nut 6, an axle is horizontally rotatably mounted on the bottom of the body 1, two wheels 18 are fixedly sleeved on the axle, and a driving motor 19 for providing a rotational driving force to the rotating rod 3 is fixedly mounted on the upper surface of the body 1.

[0017] When the grinding head 2 needs to be installed, first find the slot 7 at a suitable position, then pass the screw 5 on the top of the grinding head 2 through the slot 7, and make the grinding head 2 tightly against the mounting plate 4. Then, thread the locking nut 6 on the screw 5 until the locking nut 6 is tightly against the mounting plate 4, and then repeat the above steps to install multiple grinding heads 2.

[0018] The upper surface of the mounting plate 4 is circumferentially fixed with a plurality of spring rods 8, a movable plate 9 is fixedly installed on the top of the plurality of spring rods 8, a circular opening for the rotation rod 3 to pass through is provided in the middle of the movable plate 9, a plurality of pairs of rubber inserts 10 with convex cross sections are fixedly provided on the lower surface of the movable plate 9 in a circumferential shape, the middle portion of the rubber inserts 10 is made of a hard material, the hard material is iron, so as to avoid bending of the rubber inserts 10, a socket 11 with a convex cross section is symmetrically and vertically provided on the top of the screw rod 5, a rotation-limiting space for vertically inserting the rubber inserts 10 is formed between the mouth wall of the socket 11 and the inner wall of the locking nut 6, and the plurality of pairs of rubber inserts 10 correspond to the positions of the plurality of through grooves 7 respectively.

[0019] After the end of the screw rod 5 passes through the through groove 7, it is necessary to rotate the grinding cutter head 2 so that the two sockets 11 at the top of the screw rod 5 correspond to the positions of the two rubber inserts 10 located above it, and then the locking nut 6 is threadedly sleeved on the screw rod 5 and the screw rod 5 is locked. When multiple grinding cutter heads 2 are installed, the movable plate 9 is controlled to move downward so that multiple rubber inserts 10 are also moved downward together. The multiple rubber inserts 10 located at the top of the multiple screw rods 5 will be vertically inserted into the multiple sockets 11 corresponding to their own positions, and are respectively located in multiple rotation-limiting spaces. Since the rubber inserts 10 have good elasticity, tension and friction, after being inserted into the sockets 11, the rubber inserts 10 can play the effect of limiting the rotation of the screw rod 5. At the same time, because the friction between the contact surface of the rubber inserts 10 and the locking nut 6 will also be relatively large, it can also play a certain effect of limiting the rotation of the locking nut 6.

[0020] When the restriction needs to be released, it is only necessary to control the moving plate 9 to move upward to stretch the multiple spring rods 8 until the multiple rubber inserts 10 are respectively moved out of the multiple sockets 11 to release the restriction on the locking nut 6 and the screw 5, which is convenient and quick.

[0021] A positioning rod 12 is symmetrically fixedly mounted on the top of the grinding cutter head 2, and a plurality of pairs of positioning grooves 13 for inserting the positioning rod 12 are provided in a circular shape on the lower surface of the mounting plate 4.

[0022] When the grinding cutter head 2 needs to be installed, the two positioning grooves 13 can be aligned with the two positioning rods 12 at the required installation slots 7 and inserted until the top of the grinding cutter head 2 is against the bottom of the installation plate 4, and the top of the screw rod 5 will also pass through the slot 7, and at this time, the two sockets 11 opened on the screw rod 5 will correspond to the positions of the two rubber inserts 10 located above itself, respectively, without spending time to rotate the position of the screw rod 5 to make the sockets 11 correspond to the positions of the rubber inserts 10.

[0023] A plurality of mounting grooves 20 are provided on the upper surface of the mounting plate 4, and the plurality of mounting grooves 20 are respectively located on one side of the plurality of through-openings 26, a hollow tube 21 is horizontally fixedly installed in the mounting groove 20, an insertion rod 22 is horizontally slidably inserted in the hollow tube 21, a telescopic spring 23 is provided in the hollow tube 21, an L-shaped moving rod 24 is fixedly installed on the upper surface of one end of the insertion rod 22 located outside the hollow tube 21, a non-slip layer of rubber material is bonded to the surface of the moving rod 24, and the plurality of through-openings 26 are respectively located on the moving paths of the plurality of moving rods 24.

[0024] When the mounting plate 4 rotates at high speed, under the effect of centrifugal force, multiple insertion rods 22 will move in the direction away from the hollow tube 21, and the anti-skid layers bonded to the surfaces of some moving rods 24 will tightly abut against the surfaces of multiple locking nuts 6, thereby playing the effect of pressing the locking nuts 6 to prevent the locking nuts 6 from rotating, and further improving the tightness of the installation of the grinding head 2. When the mounting plate 4 stops rotating, the insertion rod 22 will quickly reset under the elastic potential energy of the telescopic spring 23, so that the moving rod 24 will no longer abut against the surface of the locking nut 6, thereby releasing the pressure on the locking nut 6 and facilitating the removal of the locking nut 6.

[0025] A through hole 25 is formed in the wall of the installation groove 20, and the plurality of through holes 25 are respectively connected with the plurality of through holes 26. A rotating shaft 27 is horizontally rotatably installed in the installation groove 20, and one end of the rotating shaft 27 passes through the through hole 25 and enters the through hole 26. A magnetic block 28 is fixedly installed at one end of the rotating shaft 27 located in the through hole 26. A first gear 29 is fixedly sleeved on the rotating shaft 27, and a first rack rod 30 meshingly connected with the first gear 29 is fixedly installed at one end of the insertion rod 22; In the initial state, that is, when the body 1 is not grinding and polishing the ice surface, the magnetic block 28 will face downward, and its surface will correspond to the bottom wall position of the through-hole 26, but not to the top opening position of the through-hole 26. When the body 1 starts to work and the mounting plate 4 rotates with the grinding head 2, the insertion rod 22 moves in a direction away from the hollow tube 21 under the effect of centrifugal force. At this time, the first rack rod 30 will also move, and the first gear 29 meshing with the first rack rod 30 will rotate with the rotating shaft 27. When the insertion rod 22 moves to the moving rod 24 fixedly connected to its own end and tightly abuts against the locking nut 6, the insertion rod 22 can no longer move under the action of centrifugal force, and the magnetic block 28 at the end of the rotating shaft 27 will also flip to the position where its surface corresponds to the opening of the through-hole 26, that is, the magnetic block 28 will correspond to the lower position of the locking nut 6, thereby generating a magnetic attraction on the locking nut 6, thereby strengthening the effect of restricting the rotation of the locking nut 6.

[0026] When the machine body 1 stops working, the insertion rod 22 will quickly move and reset under the elastic potential energy of the telescopic spring 23, and the first rack rod 30 will also move and reset. The first gear 29 meshing with the first rack rod 30 will rotate and reset with the rotating shaft 27 and the magnetic block 28, and the magnetic block 28 will rotate again until its surface corresponds to the bottom wall position of the through-hole 26. The magnetic block 28 no longer generates magnetic attraction on the locking nut 6, thereby facilitating the removal of the locking nut 6.

[0027] A rotating hole is vertically opened in the mounting groove 20, and a straight rod 31 is vertically rotatably installed in the rotating hole. The straight rod 31 passes through the bottom end of the mounting plate 4 and is fixedly sleeved with a connecting rod 33. A baffle 14 is fixedly installed on one end of the connecting rod 33. Multiple through grooves 7 are respectively located on the rotation paths of multiple baffles 14. The straight rod 31 is controlled to rotate by a transmission assembly. Multiple groups of transmission assemblies are respectively located in multiple mounting grooves 20. The transmission assembly includes a second rack rod 16 fixedly installed on one end of the first rack rod 30 through a connecting rod 15 and a second gear 17 fixedly sleeved on the straight rod 31. The second rack rod 16 is meshed and connected with the second gear 17. A second torsion spring 32 is sleeved on the straight rod 31. The two ends of the second torsion spring 32 are respectively fixedly connected to the lower surface of the second gear 17 and the bottom of the mounting groove 20.

[0028] In the initial state, that is, when the machine body 1 is not polishing the ice surface, the mounting plate 4 will not rotate, and the insertion rod 22 will not move under the influence of centrifugal force. The multiple baffles 14 will not cover the multiple through slots 7, making it easy to pass the screw 5 through the appropriate through slots 7 and through openings 26, thereby facilitating the installation of the grinding head 2.

[0029] When the machine body 1 is polishing the ice surface, the mounting plate 4 and the plurality of grinding heads 2 will rotate, and the plurality of insertion rods 22 will move away from the hollow tube 21 under the action of centrifugal force. During the movement, the insertion rods 22 will move with the first rack rod 30 and the second rack rod 16.

[0030] When the insertion rod 22 in the installation groove 20 on the side of the through-opening 26 where the screw rod 5 is installed moves in the direction away from the hollow tube 21 under the action of centrifugal force, the moving rod 24 fixedly connected to the end of the insertion rod 22 will abut against the locking nut 6 located on its own moving path. At this time, the first gear 29 meshing with the first rack rod 30 will rotate with the rotating shaft 27, so that the magnetic block 28 flips to the position where its own surface corresponds to the lower surface of the locking nut 6, and the second gear 17 meshing with the second rack rod 16 will rotate with the straight rod 31 and the baffle 14. However, due to the obstruction of the locking nut 6, the insertion rod 22 can no longer move to the farthest point under the action of centrifugal force, so that although the baffle 14 will rotate, it will not rotate to cover the through-opening 7.

[0031] When the insertion rod 22 in the installation groove 20 on the side of the through-opening 26 where the screw rod 5 is not installed moves in the direction away from the hollow tube 21 under the action of centrifugal force, the moving rod 24 will not be blocked by the locking nut 6, so that the insertion rod 22 will move the first rack rod 30 and the second rack rod 16 to the farthest point. At this time, the second gear 17 meshing with the second rack rod 16 will lead the straight rod 31 and the baffle 14 to rotate to the maximum angle, and the baffle 14 will rotate to completely cover the through-opening 7 where the screw rod 5 is not installed, so as to avoid that some broken ice or ice chips hit the through-opening 7 where the screw rod 5 is not installed during the grinding and polishing of the ice surface, thereby causing the through-opening 7 to be deformed, and the screw rod 5 cannot pass through normally afterwards.

[0032] When the machine body 1 stops working and the mounting plate 4 also stops rotating, the insertion rod 22 will move and reset with the first rack rod 30 and the second rack rod 16 under the elastic potential energy of the telescopic spring 23. At this time, the baffle 14 and the magnetic block 28 will rotate and reset. The baffle 14 will no longer cover the through slot 7, and the magnetic block 28 will not magnetically attract the locking nut 6, which is convenient for disassembly of the locking nut 6 and for the screw 5 to pass through the through slot 7.

[0033] In the present invention, when it is necessary to install the grinding cutter head 2, firstly, the moving plate 9 is controlled to move upward, so that the multiple spring rods 8 are stretched and the multiple rubber inserts 10 are moved upward, and then the through slot 7 at the appropriate position is found, and the screw rod 5 at the top of the grinding cutter head 2 is passed through the through slot 7, and the grinding cutter head 2 is tightly against the installation plate 4. At this time, the grinding cutter head 2 needs to be rotated, so that the screw rod 5 is rotated until the two sockets 11 at the top correspond to the positions of the two rubber inserts 10 located above itself, and then the locking nut 6 is threadedly sleeved on the screw rod 5, and the screw 5 is locked. When the multiple grinding cutter heads 2 are installed, the moving plate 9 is controlled to move downward, so that the multiple rubber inserts 10 are also moved downward together, and the positions are adjusted. The multiple rubber inserts 10 at the top ends of the multiple screw rods 5 will be vertically inserted into the multiple sockets 11 corresponding to their own positions, and will be located in the multiple rotation limiting spaces. Since the rubber inserts 10 have good elasticity, tension and friction, and the cross-sectional shapes of the rubber inserts 10 and the sockets 11 are both convex, after being inserted into the sockets 11, the rubber inserts 10 can limit the rotation of the screw rods 5. At the same time, since the friction between the contact surface of the rubber inserts 10 and the locking nut 6 is also relatively large, it can also limit the rotation of the locking nut 6 to a certain extent, thereby avoiding loosening of the connection between the grinding head 2 and the mounting plate 4, thereby improving the tightness of the installation of the grinding head 2.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
