Description

Technical Field

[0001] The present application relates to the technical field of vehicle auxiliary equipment, and in particular to a vehicle anti-skid and anti-sinking device. Background Art

[0002] Power grid maintenance vehicles are essential equipment for maintenance workers. Because power equipment is widely distributed, maintenance operations often involve difficult terrain, such as muddy, sandy, and snowy surfaces. These conditions can be difficult for vehicles to navigate, significantly impacting the timeliness of maintenance work. To further improve maintenance efficiency, anti-slip design for vehicles is crucial.

[0003] Chinese patent announcement No. CN201872547U discloses an anti-skid and anti-sinking device for transport vehicles, comprising at least six anti-skid and anti-sinking blocks of rubber composite materials, a longitudinal connecting steel chain connected in series with the anti-skid and anti-sinking blocks, and two transverse connecting steel chains are respectively arranged on at least half of the anti-skid and anti-sinking blocks, and the two open ends of the longitudinal connecting steel chains are each provided with a screw, which is closed after being connected by a connector, and one end of the two transverse connecting steel chains on the anti-skid and anti-sinking blocks on which the transverse connecting steel chains are provided is connected to the anti-skid and anti-sinking blocks, and the other end is each provided with a screw, and the two screws are connected and fixed to the wheels through a connector. The utility model has the dual functions of anti-skid and anti-sinking, good effect, and good versatility, and is suitable for transport vehicles of different specifications to travel on soft ground such as muddy ground, sandy ground, and snowy ground. At the same time, the utility model has the advantages of simple structure, light weight, easy installation and disassembly and use, wear resistance, long service life, no damage to tires and road surfaces, and good operability and practicality.

[0004] However, the following problems still exist in the actual use of this patent:

[0005] 1. When the device is used to pass through muddy roads, the contact area between the vehicle and the ground has not changed significantly, so the vehicle will still sink into the mud pit, making it impossible for the vehicle to pass normally.

[0006] 2. When passing through muddy sections, the sludge will directly adhere to the surface of the device, so a thick layer of mud will be covered on the device, causing the device to lose sufficient friction and still have difficulty moving forward.

[0007] 3. The device is not convenient for adjusting its own width according to the width of the wheel, so the scope of application of the device is small. Summary of the Invention

[0052] The following will clearly and completely describe the technical solutions of the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the embodiments of the present application.

For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0055] The embodiment of the present application discloses a vehicle anti-skid and anti-sinking device.

[0056] See also Figure 1 as well as Figure 3 An embodiment of a vehicle anti-skid and anti-sinking device provided in the embodiments of the present application includes:

[0057] The wheels 2 are mounted on the bottom of the vehicle body 1 .

[0058] More importantly, it also includes a retractable drive 3, auxiliary wheels 5, a mud scraper frame 4 and an anti-skid structure 6.

[0059] The auxiliary wheel 5 is pivotally connected to the scraper frame 4, and the anti-skid structure 6 is wrapped around the auxiliary wheel 5 and the wheel 2. The scraper frame 4 is used to scrape some of the mud that passes over the anti-skid structure 6. The auxiliary wheel 5 allows both the wheel 2 and the auxiliary wheel 5 to contact the ground simultaneously, thereby increasing the contact area between the vehicle and the ground. This distributes the vehicle's weight over a larger area and facilitates the vehicle's passage through muddy and soft ground. Furthermore, by wrapping the anti-skid structure 6 around the wheel 2 and the auxiliary wheel 5, a passable platform is formed behind the wheel 2 and in front of the auxiliary wheel 5, thereby preventing direct friction between the wheel 2 and the ground and reducing the amount of mud that is stirred up by the wheel 2 due to friction. In other words, the auxiliary wheel 5 cooperates with the wheel 2 to ensure sufficient contact area between the anti-skid structure 6 and the ground, thereby reducing the local pressure exerted by the vehicle on the ground and improving the vehicle's maneuverability.

[0060] The retractable drive 3 is installed at the bottom of the vehicle body 1 and is located on one side of the wheel 2. The driving end of the retractable drive 3 is connected to the scraper frame 4, which is used to adjust the height of the auxiliary wheel 5 by driving the scraper frame 4 to move. When the auxiliary wheel 5 is needed, the height of the scraper frame 4 can be adjusted by the retractable drive 3 until the auxiliary wheel 5 contacts the ground. When the auxiliary wheel 5 is not in use, the height of the scraper frame 4 can be adjusted until the auxiliary wheel 5 leaves the ground, and the auxiliary wheel 5 can be retracted under the vehicle body 1, so as not to affect the normal movement of the vehicle on the road. The scraper frame 4 can be used as a mounting frame for the auxiliary wheel 5 to assist the rotation of the auxiliary wheel 5. It can also scrape some of the mud adhering to the surface of the anti-skid structure 6 when the anti-skid structure 6 rotates, so that the anti-skid structure 6 maintains sufficient friction and improves the vehicle's passability.

[0061] The anti-slip structure 6 includes multiple anti-slip parts 60; the multiple anti-slip parts 60 are all telescopically adjustable, and adjacent anti-slip parts 60 are hingedly connected to each other. In this way, the telescopic adjustment design can be used to adapt to wheels 2 and auxiliary wheels 5 of different widths, thereby expanding the scope of application of the device.

[0062] The above is the first embodiment of a vehicle anti-skid and anti-sinking device provided by the embodiment of the present application. The following is the second embodiment of a vehicle anti-skid and anti-sinking device provided by the embodiment of the present application. For details, please refer to Figures 1 to 4 .

[0063] Based on the solution of the above embodiment 1:

[0064] Furthermore, the retractable driver 3 can be designed as a lifting driver, which is vertically installed at the bottom of the vehicle body 1. Specifically, the retractable driver 3 can be a hydraulic push rod.

[0065] Further, with respect to the design of the scraper frame 4, it can be designed as follows Figure 1 as well as Figure 2In the U-shaped frame structure shown, the auxiliary wheel 5 is pivotally connected to the inner wall of the scraper frame 4 through a rotating shaft.

[0066] Furthermore, in order to facilitate the assembly and disassembly of the anti-slip structure 6 at both ends and improve the usability, the first anti-slip component 60 is designed to be detachably hingedly connected to the last anti-slip component 60 via a connector 70 .

[0067] like Figure 4 As shown, further, in terms of the structural design of the anti-slip member 60, it includes a positioning plate 601 and two support plates 602. The positioning plate 601 and the support plate 602 can be strip-shaped structures as a whole, without limitation.

[0068] Each of the two support plates 602 has an insertion slot 6021, and two side surfaces of the insertion slots 6021 have sliding slots 6022. The two ends of the positioning plate 601 are inserted into the two insertion slots 6021, one for each side. Sliders 6011 are provided on the side walls of the plate section of the positioning plate 601 that inserts into the insertion slots 6021. These slides 6011 engage with and slidably engage with the sliding slots 6022. The engagement between the slides 6011 and the sliding slots 6022 allows for adjustment of the overall length between the support plate 602 and the positioning plate 601 to accommodate wheels 2 and auxiliary wheels 5 of varying widths. The slides 6011 and the sliding slots 6022 are connected in a sliding manner with a certain interference fit, meaning that a certain amount of force is required to allow the slides 6011 and the sliding slots 6022 to slide.

[0069] Furthermore, a rotatable limiting plate 603 is connected to each end of the anti-slip member 60; specifically, the limiting plate 603 is connected to the end of the support plate 602, and a bent portion can be provided at the end of the support plate 602, and the rotatable limiting plate 603 is connected to the bent portion via a rotating shaft. At the same time, an elastic member 604 is also connected between the limiting plate 603 and the anti-slip member 60, so that the limiting plate 603 can be closely attached to the outer side of the auxiliary wheel 5 or the wheel 2. Through this design, after the anti-slip structure 6 is wrapped around the surface of the auxiliary wheel 5 and the wheel 2, the elastic member 604 can make the limiting plate 603 closely attached to both sides of the auxiliary wheel 5 and the wheel 2, so that the limiting plate 603 can be used to limit the wrapping position of the anti-slip structure 6, thereby ensuring the reliability of the connection between the anti-slip structure 6 and the wheel 2 and the auxiliary wheel 5.

[0070] Furthermore, the elastic member 604 can be designed as a spring. Specifically, one end of the elastic member 604 is fixedly connected to the anti-slip member 60, and the other end is in movable contact with the limit plate 603, that is, it supports the limit plate 603. Of course, the elastic member 604 can also be a torsion spring, which is provided on the rotating shaft connecting the limit plate 603 and the support plate 602, and is further connected to the limit plate 603 and the support plate 602 respectively. There is no specific limitation.

[0071] In addition, it should be noted that in the present application, not all anti-slip members 60 may have limit plates 603 at both ends, but a certain number of anti-slip members 60 may have limit plates 603 at both ends, and the certain number of anti-slip members 60 may be evenly distributed, for example Figure 3 As shown, two of every three anti-slip parts 60 are equipped with limiting plates 603, while the anti-slip part 60 located between the two anti-slip parts 60 equipped with limiting plates 603 is not equipped with limiting plates 603, and there is no specific limitation.

[0072] Furthermore, with regard to the hinged design between any two adjacent positioning plates 601 from the first positioning plate 601 to the last positioning plate 601, a first connecting plate 605 rotatably connected to the positioning plate 601 can be provided between the adjacent positioning plates 601, and the positioning plate 601 and the first connecting plate 605 can also be connected via a rotating shaft.

[0073] Furthermore, the design of the connector 70 includes two second connecting plates 701 and a connecting sleeve 702 .

[0074] One second connecting plate 701 is rotatably connected to the first positioning plate 601 via a rotating shaft, and another second connecting plate 701 is rotatably connected to the last positioning plate 601 via a rotating shaft.

[0075] A boss portion 7011 is provided on one end of each of the two second connecting plates 701, and preferably, a boss portion 7011 is provided on both ends, that is, the structure of the second connecting plate 701 can be designed as a cross. In order to unify the spare parts, the structure of the first connecting plate 605 can also be designed as a cross like the second connecting plate 701, and then the corresponding connecting sleeve 702 is also designed to be two.

[0076] The connecting sleeve 702 includes two sleeves 7021 that are rotatably connected to each other. The two sleeves 7021 are sleeved on the boss portion 7011 on one end of the second connecting plate 701 in a one-to-one correspondence.

[0077] As for the detachable connection between the kit 7021 and the boss portion 7011, a threaded hole is provided on the kit 7021, and a threaded fastener 7022 such as a screw, bolt, or screw is inserted into the threaded hole, and one end of the threaded fastener 7022 can abut against the boss portion 7011.

[0078] The design of the connecting sleeve 702 allows for quick assembly and disassembly of the two second connecting plates 701, thereby enabling quick assembly and disassembly of the first positioning plate 601 and the last positioning plate 601. Furthermore, the design of the connector 70 also allows the anti-skid structure 6 to be segmented, meaning that multiple segments of the anti-skid structure 6 can be quickly connected via the connector 70. This allows the overall length to be adjusted based on the size of the wheel 2 and the auxiliary wheel 5, thus adapting to different vehicles and further improving applicability.

[0079] The electrical components appearing in this application are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device that plays a control role such as a computer.

[0080] The working steps of the device designed in this application can be as follows:

[0081] 1. Start the retractable drive 3 to lower the auxiliary wheel 5 to the ground so that it contacts the ground together with the wheel 2. Then, lay the anti-skid structure 6 in front of the wheel 2. Start the vehicle so that the wheel 2 and the auxiliary wheel 5 move above the anti-skid structure 6.

[0082] 2. Wrap the anti-skid structure 6 around the wheel 2 and the auxiliary wheel 5 and connect them end to end. Then put the connecting sleeve 702 on the two second connecting plates 701 and tighten the threaded fasteners 7022 from both sides.

[0083] 3. Continue to start the vehicle to drive the auxiliary wheels 5 and the anti-skid structure 6 to move.

[0084] 4. After use, loosen the threaded fastener 7022, remove the connecting sleeve 702, drive the vehicle away from the anti-skid structure 6, retract the anti-skid structure 6, and then start the retractable drive 3 to retract the auxiliary wheel 5 to the bottom of the vehicle.

[0085] The above is a detailed introduction to a vehicle anti-skid and anti-sinking device provided by the present application. For those skilled in the art, according to the ideas of the embodiments of the present application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
