Description

Technical Field

[0001] The invention relates to the technical field of anti-skid chains, and in particular to an automatic loading and unloading device for anti-skid chains. Background Art

[0002] When driving on slippery roads such as ice, snow, and mud, the tires of vehicles are prone to slipping, seriously affecting driving safety. Anti-skid chains are a commonly used safety device that effectively improves the vehicle's passability by increasing the friction between the tires and the ground.

[0003] The installation environment of anti-skid chains is often poor, such as in cold snowy areas or muddy roads. If the driver gets out of the car and manually wraps the chain around the tire and fixes it with buckles or bolts, it will often be very inconvenient. First, the surface temperature of the metal parts of the anti-skid chain is extremely low, and bare-handed contact can easily cause frostbite. The driver needs to wear heavy gloves to operate, which greatly reduces the flexibility of his fingers and makes it difficult to complete fine movements such as buckling and bolting.

[0004] In snowy environments, snow covers tires and wheels, and snow must be cleared before snow chains can be installed, further increasing operation time and physical exertion. For example, in a snowstorm, drivers may need to kneel on the snow to work, and their clothes may get soaked, causing the risk of hypothermia. Summary of the invention

[0019] When the gear ring rotates, it can sequentially drive the plurality of second driven gears to rotate, so that the plurality of second drive racks sequentially move toward or away from the center of the placement frame;

[0020] The free end of the second driving rack is connected with a limiting piece for limiting the anti-skid chain on the storage roller, the placement frame is connected with a second servo motor for driving the gear ring to rotate, and the connection frame is connected with a third servo motor for driving the connection disk to rotate.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-10 The present invention provides a technical solution: an automatic skid chain loading and unloading device, comprising a connection frame 1 for storing the skid chain and a tire body 2 rotatably connected to the connection frame 1, comprising:

[0041] There are at least two mounting frames 301, which are symmetrically connected to both sides of the tire body 2, and a resisting plate 302 is rotatably connected inside the mounting frame 301;

[0042] A plurality of storage frames 303 are connected in the installation frame 301 and are arranged in a circular array with the center of the installation frame 301 as the center. A sliding member 304 is slidably connected in the storage frame 303. The top and bottom of the sliding member 304 extend to the outside of the storage frame 303. The top is connected to a material taking member, and the bottom is connected to a resistance roller 307.

[0043] When the contact plate 302 rotates around the center of the mounting frame 301, it can intermittently contact each of the contact rollers 307 in turn, driving the sliding member 304 and the material taking member to slide vertically upward along the length direction of the storage frame 303, so as to grab the anti-skid chain in the connection frame 1;

[0044] The first return spring 305 has one end connected to the storage frame 303 and the other end connected to the sliding member 304 for assisting the sliding member 304 to slide back and forth. The installation frame 301 is connected to a first servo motor 306 for driving the resistance plate 302 to rotate.

[0045] It should be noted that, in the present application, the anti-skid chain used is not an integral or one-piece anti-skid chain, but a segmented, separate anti-skid chain, which is arranged in the connecting frame 1. As the multiple material taking parts move sequentially, the multiple anti-skid chains can be taken out from the connecting frame 1 in sequence, and fixed in a circular array on the outer surface of the tire body 2 to achieve an anti-skid effect, and an installation port can be opened at the top of the connecting frame 1 for storing the anti-skid chain in the connecting frame 1, or taking it out for maintenance.

[0046] In specific implementation, when it is necessary to install the anti-skid chain, start the first servo motor 306 in the installation frame 301. The first servo motor 306 starts working, driving the contact plate 302 to rotate in a circle around the center of the installation frame 301. As the contact plate 302 rotates, it will intermittently and sequentially contact the contact rollers 307 at the bottom of each storage frame 303. When the contact plate 302 contacts a certain contact roller 307, an upward force is applied to the contact roller 307. Since the contact roller 307 is connected to the bottom of the sliding member 304, this upward force will push the sliding member 304 to overcome the elastic force of the first return spring 305 and slide vertically upward along the length direction of the storage frame 303. The material picking member connected to the top of the sliding member 304 moves upward accordingly, close to the anti-skid chain in the connection frame 1. When the material picking member reaches the appropriate position, the material picking member will grab the segmented anti-skid chain;

[0047] Under the continuous driving of the first servo motor 306, the abutment plate 302 continues to rotate and leaves the abutment roller 307 that is currently abutting. At this moment, the first return spring 305 begins to play a role, and it will pull the sliding member 304 to slide downwards and return to its original position.

[0048] The pick-up member moves downward with the sliding member 304 with the grabbed anti-skid chain. When it moves to a suitable position, the pick-up member fixes the anti-skid chain on the outer surface of the tire body 2 .

[0049] The first servo motor 306 continuously drives the abutment plate 302 to rotate, so that the plurality of material-picking parts repeat the above-mentioned grabbing and installation process in sequence. As the plurality of material-picking parts move in sequence, the plurality of segmented anti-skid chains are taken out from the connection frame 1 in sequence and fixed on the outer surface of the tire body 2 in a circular array, finally achieving an anti-skid effect. When the required anti-skid chains are all installed on the tire body 2, the first servo motor 306 stops working.

[0050] See also Figure 7 and Figure 8 , the material picking parts include,

[0051] A fixed frame 401 is connected to the top of the sliding member 304, and a first driving rack 402 is slidably disposed in the fixed frame 401;

[0052] The two first driven gears 403 are symmetrically connected to the fixed frame 401, the first driving rack 402 is meshed with the two first driven gears 403, the first driven gears 403 are connected to a connecting plate 404, the other end of the connecting plate 404 extends to the outside of the fixed frame 401 and is connected to a clamping member 405, wherein:

[0053] A driving member for driving the first driving rack 402 to move back and forth vertically is also disposed in the fixed frame 401 .

[0054] In a specific implementation, when the material picking member approaches the anti-skid chain, the driving member in the fixed frame 401 starts to work, driving the first driving rack 402 to slide vertically upward in the fixed frame 401 .

[0055] Since the first driving rack 402 is meshed with two first driven gears 403 symmetrically connected to the fixed frame 401, when the first driving rack 402 moves upward, it will drive the two first driven gears 403 to rotate simultaneously. The two first driven gears 403 rotate in opposite directions and perform circular motion around their respective rotation axes;

[0056] The connecting plate 404 connected to the first driven gear 403 moves with the rotation of the first driven gear 403, and the other end of the connecting plate 404 extends to the outside of the fixed frame 401 and is connected to a clamping member 405. As the first driven gear 403 rotates, the connecting plate 404 drives the clamping member 405 to move closer to the middle. When the material picking part reaches the appropriate position, the two clamping members 405 close, tightly clamping the segmented anti-skid chain, completing the grabbing action of the anti-skid chain;

[0057] When the abutment plate 302 leaves the abutment roller 307, the first return spring 305 pulls the sliding member 304 to slide downward and return to its original position. The material picking member moves downward with the sliding member 304 with the grabbed anti-skid chain to a suitable installation position on the outer surface of the tire body 2 to fix the anti-skid chain.

[0058] See also Figure 8 , driving parts include,

[0059] The compressed air bag 501 is connected in the storage frame 303. The bottom of the compressed air bag 501 is connected to a reversing switch 502. The fixed frame 401 is connected to an inflatable air bag 503. The compressed air bag 501 is connected to the inflatable air bag 503 through a connecting pipe for conveying gas into the inflatable air bag 503, so that the first driving rack 402 slides vertically upward.

[0060] The battery 504 is connected in the fixed frame 401 . One side of the battery 504 is electrically connected to the electromagnet 505 . The other side of the electromagnet 505 is connected to the second return spring 506 . The other end of the second return spring 506 is interconnected with the first driving rack 402 .

[0061] It should be noted that the reversing switch 502 is electrically connected to the battery 504 and is used to control the current direction of the battery 504, thereby achieving the effect of controlling the magnetism of the electromagnet 505, that is, converting it to the N pole or the S pole, and the first drive rack 402 is made of magnetic material and can be used in conjunction with the electromagnet 505 to achieve a better fixing effect.

[0062] In specific implementation, when the first servo motor 306 drives the contact plate 302 to rotate, so that the contact plate 302 contacts the contact roller 307, and pushes the sliding member 304 to slide upward along the storage frame 303, the compressed air bag 501 connected to the storage frame 303 is squeezed by the sliding member 304, and the gas in the compressed air bag 501 is transported to the inflatable air bag 503 in the fixed frame 401 through the connecting pipe. The inflatable air bag 503 expands due to the filling of gas, generating an upward thrust. This thrust acts on the first drive rack 402, pushing the first drive rack 402 to slide vertically upward in the fixed frame 401, thereby completing the clamping action;

[0063] After the first drive rack 402 rises to a suitable position and completes grabbing the anti-skid chain, the reversing switch 502 is electrically connected to the battery 504 to control the direction of the current supplied by the battery 504 to the electromagnet 505, so that the electromagnet 505 generates specific magnetism. Since the first drive rack 402 is made of magnetic material, the magnetic force generated by the electromagnet 505 will adsorb the first drive rack 402 to keep it in the current position, ensuring that during the descent of the sliding member 304, the anti-skid chain will not fall off due to the movement of the first drive rack 402, thereby fixing the anti-skid chain.

[0064] See also Fig. 9 A storage roller 701 for placing an anti-skid chain is rotatably connected in the connection frame 1, and both ends of the storage roller 701 are connected to a connection disk 702, and a placement frame 703 is connected to the connection disk 702. A gear ring 704 is rotatably connected in the placement frame 703, and a plurality of second driven gears 705 distributed in a circular array with the center of the placement frame 703 as the center are rotatably connected in the placement frame 703. The gear ring 704 is meshed with the second driven gear 705, and the second driven gear 705 is meshed with a second driving rack 706, wherein,

[0065] When the gear ring 704 rotates, it can sequentially drive the plurality of second driven gears 705 to rotate, so that the plurality of second driving racks 706 sequentially move toward or away from the center of the placement frame 703;

[0066] The free end of the second driving rack 706 is connected to a limiting piece for limiting the anti-skid chain on the storage roller 701, the placement frame 703 is connected to a second servo motor 707 for driving the gear ring 704 to rotate, and the connection frame 1 is connected to a third servo motor 708 for driving the connecting disk 702 to rotate.

[0067] It should be noted that a magnetic plate may be connected to the top of the contact plate 302, and a Hall sensor may be connected in the mounting frame 301, so that the Hall sensor transmits the rotation speed of the contact plate 302 to the second servo motor 707 and the third servo motor 708 so that the rotation speeds of the second servo motor 707 and the third servo motor 708 and the contact plate 302 are the same, and the rotation speed of the contact plate 302 is monitored in real time through the magnetic plate and the Hall sensor, and the second servo motor 707 and the third servo motor 708 are synchronously controlled to ensure that the release of the anti-skid chain is accurately matched with the material picking action, thereby avoiding grabbing failure due to speed difference;

[0068] The gear ring 704 is a special-shaped gear ring 704, which is used to drive the plurality of second driven gears 705 to transmit in sequence.

[0069] In specific implementation, the segmented anti-skid chain is set on the storage roller 701, and the second servo motor 707 drives the gear ring 704 to rotate. The gear ring 704 engages with multiple second driven gears 705 in turn, driving the corresponding second drive rack 706 to move away from the center of the storage roller 701, thereby controlling the limiter to open the anti-skid chain to facilitate the grabbing of the material.

[0070] refer to Fig.10 The limiting member includes a plurality of mounting seats 801 connected to the connecting disk 702, the number and position of the plurality of mounting seats 801 correspond to the second driving rack 706, the free end of the second driving rack 706 is rotatably connected to a connecting block 802, the connecting block 802 and the mounting seat 801 are rotatably connected to each other to form a lever mechanism, the other end of the connecting block 802 is connected to a positioning member 804 for limiting the anti-skid chain, the connecting disk 702 is connected to a third return spring 803, and the other end of the third return spring 803 is connected to the connecting block 802.

[0071] In specific implementation, when the gear ring 704 rotates to drive the second driving rack 706 to move away from the center of the storage roller 701, the rack pushes the lever mechanism through the connecting block 802, and the lever mechanism formed by the connecting block 802 and the mounting seat 801 converts the linear displacement of the rack into the rotational movement of the positioning member 804. Since the lever fulcrum is close to the mounting seat 801, the free end of the positioning member 804 obtains a larger displacement, quickly detaches from the anti-skid chain, and facilitates the subsequent grabbing of the anti-skid chain.

[0072] refer to Figure 7 A short-circuit seat is connected inside the storage frame 303, one end of the first return spring 305 is connected to the short-circuit seat, and the other end is connected to the sliding member 304. A guide rod 6 is slidably connected to the short-circuit seat, and the other end of the guide rod 6 is connected to the sliding member 304. The first return spring 305 is sleeved on the guide rod 6.

[0073] During specific implementation, the guide rod 6 can limit and guide the sliding of the sliding member 304, thereby improving the stability of the sliding member 304 during the sliding process.

[0074] refer to Figure 6 The connecting plate 702 is connected to a mounting frame 9 , and the third servo motor 708 is connected to the mounting frame 9 .

[0075] During specific implementation, the provided mounting frame 9 facilitates the installation of the third servo motor 708 .

[0076] refer to Figure 4 The two clamping members 405 have anti-skid patterns formed on opposite sides thereof to improve the positioning effect of the anti-skid chain.

[0077] In specific implementation, the anti-skid patterns provided enhance the fixing effect of the anti-skid chain and prevent the anti-skid chain from deviating during use.

[0078] Working principle: The segmented anti-skid chain is neatly placed on the storage roller 701 in the connection frame 1. In the initial state, the positioning pieces 804 on the connection plates 702 at both ends of the storage roller 701 tightly press the anti-skid chain on the storage roller 701 through the tension of the third return spring 803 to prevent it from loosening or slipping.

[0079] The magnetic plate connected to the top of the contact plate 302 and the Hall sensor in the mounting frame 301 start working. The Hall sensor monitors the rotation speed of the contact plate 302 in real time and transmits the rotation speed signal to the second servo motor 707 and the third servo motor 708 to ensure that the rotation speed of the two motors is consistent with the contact plate 302, so as to prepare for the subsequent accurate release and grabbing of the anti-skid chain.

[0080] When it is necessary to install the anti-skid chain, start the first servo motor 306 in the installation frame 301. The first servo motor 306 drives the contact plate 302 to rotate in a circle around the center of the installation frame 301. During the rotation of the contact plate 302, it will intermittently conflict with the contact rollers 307 at the bottom of each storage frame 303 in turn. When conflicting, an upward force is applied to the contact roller 307. Since the contact roller 307 is connected to the bottom of the sliding member 304, this force pushes the sliding member 304 to overcome the elastic force of the first return spring 305 and slide vertically upward along the length direction of the storage frame 303. The guide rod 6 slides on the short-circuit seat to limit and guide the sliding member 304, thereby improving its sliding stability.

[0081] When the sliding member 304 slides upward, it squeezes the compressed air bag 501 in the receiving frame 303. The gas in the compressed air bag 501 is transported to the inflatable air bag 503 in the fixed frame 401 through the connecting pipe under the action of pressure.

[0082] The inflatable airbag 503 expands due to the filling of gas, generating an upward thrust, pushing the first drive rack 402 to slide vertically upward in the fixed frame 401. The first drive rack 402 meshes with the two first driven gears 403 symmetrically connected to the fixed frame 401, driving the two first driven gears 403 to rotate in opposite directions at the same time. The connecting plate 404 on the first driven gear 403 moves accordingly, driving the clamping member 405 to move closer to the middle. When the material picking member rises to a suitable position with the sliding member 304, the two clamping members 405 close, and the anti-skid patterns on the opposite side increase the friction with the anti-skid chain, tightly clamping the segmented anti-skid chain to complete the grabbing action.

[0083] After the first drive rack 402 rises to a suitable position and the anti-skid chain is caught, the reversing switch 502 is electrically connected to the battery 504 to control the direction of the current supplied by the battery 504 to the electromagnet 505, so that the electromagnet 505 generates a specific magnetism. Since the first drive rack 402 is made of magnetic material, the magnetic force generated by the electromagnet 505 attracts the first drive rack 402 to keep it at the current position, ensuring that the anti-skid chain will not fall off due to the movement of the first drive rack 402 during the descent of the sliding member 304.

[0084] At the same time, the second servo motor 707 drives the special-shaped gear ring 704 to rotate, and the gear ring 704 meshes with the plurality of second driven gears 705 in sequence, driving the corresponding second drive rack 706 to move away from the center of the storage roller 701. The second drive rack 706 pushes the lever mechanism composed of the connecting block 802 and the mounting seat 801 through the connecting block 802, and converts the linear displacement of the rack into the rotational movement of the positioning member 804. The free end of the positioning member 804 obtains a larger displacement, quickly disengages from the anti-skid chain, and facilitates the grabbing of the material.

[0085] Under the continuous drive of the first servo motor 306, the contact plate 302 continues to rotate and leaves the current contact roller 307. At this time, the first return spring 305 pulls the sliding member 304 to slide downward and return to its original position. The material taking member moves downward with the captured anti-skid chain along with the sliding member 304 to a suitable installation position on the outer surface of the tire body 2, achieving the effect of automatically installing the anti-skid chain.
