Description

Technical Field

[0001] This utility model belongs to the field of engineering machinery technology, and more specifically, it relates to a skid steer loader. Background Technology

[0002] Skid steer loaders, also known as skid steer loaders, multi-purpose engineering vehicles, or multi-purpose engineering machines, are wheeled specialized chassis equipment that achieves vehicle steering by utilizing the difference in linear speed between the wheels on both sides. Because the minimum turning radius of a skid steer loader is less than half that of a conventional loader of the same class, it can almost turn on the spot, making it particularly suitable for operations in narrow spaces such as urban infrastructure, roads or construction sites, factory workshops, warehouses, docks, ship decks, and even ship cabins.

[0003] Existing skid steer loaders may tip over in the direction of the material when lifting heavy loads, potentially causing injury to personnel inside the loader and damage to the material, thus limiting their practicality. Therefore, this paper studies and improves upon existing structures and shortcomings to provide a skid steer loader with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a skid steer loader, which is achieved by the following specific technical means:

[0005] A skid steer loader includes a skid steer loader body. A mounting base is fixedly installed on one side of the skid steer loader body. Two sets of anti-tipping mechanisms are symmetrically installed on one side of the mounting base. Each anti-tipping mechanism includes a fixed base fixedly connected to the mounting base. A movable base is slidably connected to the inner side of the fixed base. The movable base has a mounting groove. A rotating shaft is fixedly connected to the inner side of the mounting groove. A rotating plate is rotatably connected to the outer side of the rotating shaft. A support tube is installed on one side of the rotating plate. A caster wheel is fixedly installed on one end of the support tube. The fixed base has a through groove for the rotating plate to rotate.

[0006] Furthermore, a stud is fixedly installed on one side of the rotating plate, and a threaded cylinder is threadedly connected to the outer side of the stud. One side of the threaded cylinder is fixedly connected to one end of the support tube.

[0007] Furthermore, a limiting seat is fixedly installed on one end of the stud, and the outer diameter of the limiting seat is equal to the inner diameter of the support tube.

[0008] Furthermore, the outer side of the threaded cylinder is provided with anti-slip texture.

[0009] Furthermore, a cover plate is fixedly installed on the top of the movable seat by fasteners, and a handle is fixedly installed on the top side of the cover plate.

[0010] Furthermore, a hydraulic cylinder is installed on the bottom side of the cover plate. Both sides of the hydraulic cylinder are rotatably connected to connecting pins via connecting shafts. One side of each connecting pin is fixedly connected to the bottom side of the cover plate. A drive frame is fixedly installed on the output end of the hydraulic cylinder. The drive frame is rotatably connected to a connecting frame via a rotating shaft. One side of the connecting frame is fixedly connected to one side of the rotating plate.

[0011] Furthermore, the fixed base has multiple sets of through holes on both sides, and the movable base has multiple sets of screw holes corresponding to the multiple sets of through holes. The inner side of each set of through holes and screw holes is connected to a bolt, and the bolt is threadedly connected to the screw hole.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through the cooperation of a hydraulic cylinder and a drive frame, enables the flexible rotation of a rotating plate. The cooperation of the rotating plate and studs allows for the flexible movement of the support column and casters. This allows the casters to be moved and brought into contact with the ground when anti-tipping protection of the skid steer loader is needed, increasing the stability of the skid steer loader. When anti-tipping protection is not required, the rotating plate and casters can be folded and stored, increasing the product's practicality. Attached Figure Description

[0023] As attached Figure 1 To be continued Figure 4 As shown:

[0024] This utility model provides a skid steer loader, including a skid steer loader body 1. A mounting base 2 is fixedly installed on one side of the skid steer loader body 1. Two sets of anti-tipping mechanisms are symmetrically installed on one side of the mounting base 2. The anti-tipping mechanism includes a fixed base 3 fixedly connected to the mounting base 2. A movable base 4 is slidably connected to the inner side of the fixed base 3. The movable base 4 is provided with a mounting groove. A rotating shaft 5 is fixedly connected to the inner side of the mounting groove. A rotating plate 6 is rotatably connected to the outer side of the rotating shaft 5. A support tube 7 is installed on one side of the rotating plate 6. A caster wheel 11 is fixedly installed on one end of the support tube 7. The fixed base 3 is provided with a through groove for the rotating plate 6 to rotate.

[0025] A stud 8 is fixedly installed on one side of the rotating plate 6, and a threaded cylinder 9 is threadedly connected to the outside of the stud 8. One side of the threaded cylinder 9 is fixedly connected to one end of the support tube 7, which can drive the support tube 7 to move flexibly.

[0026] A limiting seat 10 is fixedly installed on one end of the stud 8 to prevent the threaded cylinder 9 from falling off the stud 8. The outer diameter of the limiting seat 10 is equal to the inner diameter of the support tube 7, which increases the stability of the support tube 7 when it moves.

[0027] The threaded cylinder 9 has anti-slip textures on its outer side to facilitate the operator's rotation of the threaded cylinder 9.

[0028] The top of the movable seat 4 is fixedly installed with a cover plate 18 by fasteners, and a handle 19 is fixedly installed on the top side of the cover plate 18, which can make the movable seat 4 easy to move.

[0029] Hydraulic cylinder 12 is installed on the bottom side of cover plate 18. Connecting pins 13 are rotatably connected to both sides of hydraulic cylinder 12 via connecting shafts. One side of each connecting pin 13 is fixedly connected to the bottom side of cover plate 18. Drive frame 14 is fixedly installed on the output end of hydraulic cylinder 12. Drive frame 14 is rotatably connected to connecting frame 16 via rotating shaft 15. One side of connecting frame 16 is fixedly connected to one side of rotating plate 6, which can realize the automatic rotation of rotating plate 6.

[0030] The fixed base 3 has multiple sets of through holes on both sides, and the movable base 4 has multiple sets of screw holes corresponding to the multiple sets of through holes. The inner side of each set of through holes and screw holes is connected to a bolt 17. The bolt 17 is threadedly connected to the screw hole, which can make it easy to detach and install the movable base 4 from the fixed base 3.

[0031] The working principle of this embodiment is as follows: When it is necessary to protect the skid steer loader body 1 from tipping over, the hydraulic cylinder 12 is activated to drive the drive frame 14 to move. The drive frame 14 drives the connecting frame 16 to move. The connecting frame 16 drives the rotating plate 6 to rotate. The rotating plate 6 drives the support pipe 7 and the caster wheel 11 to move. After the rotating plate 6 has moved, the rotating threaded cylinder 9 drives the support pipe 7 to move and makes the caster wheel 11 contact the ground. This effectively prevents the skid steer loader body 1 from tipping over towards the material when it lifts a heavy material.
