Description

Technical Field

[0001] This utility model relates to the field of loader technology, specifically to an anti-tipping device for a side-dump loader. Background Technology

[0002] Loaders are earthmoving machines widely used in construction projects such as highways, railways, buildings, hydropower, ports, and mines. They are primarily used for loading and unloading bulk materials such as soil, sand, gravel, lime, and coal. They can also perform light digging operations on ores and hard soil. With different auxiliary working devices, they can also perform bulldozing, lifting, and loading / unloading operations on other materials such as timber. Due to their advantages of high operating speed, high efficiency, good maneuverability, and easy operation, loaders have become one of the main types of machinery used in earthmoving construction. Existing anti-tipping protection devices for loaders (announcement number: CN218667716U) have at least the following defects in use:

[0003] In the above solution, the anti-tipping protection device for the loader provides an anti-tipping protection mechanism, which greatly improves the stability of the loader and reduces the risk of tipping over. However, in actual use, the side-tipping protection device in the above solution is located on the top side of the vehicle body, which means that the device may still tip over. It only provides enough space to prevent the driver from being crushed, and there is still a risk of tipping over during construction. Therefore, an anti-tipping device for side-dumping loaders needs to be developed. Utility Model Content

[0004] The main purpose of this utility model is to provide an anti-tipping device for a side-dump loader, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An anti-tipping device for a side-dump loader includes a loader cab. A fixed support frame is fixedly connected to the outer side of the loader cab. Two sets of symmetrically distributed lifting sliding holes are opened on the top side of the fixed support frame. A positioning sliding column is slidably connected between the inner walls of each lifting sliding hole. A support spring is fixedly connected to the bottom end of each positioning sliding column. A support foot is fixedly connected to the bottom end of each support spring. A lifting plate is fixedly connected to the top side of all the positioning sliding columns. A support lift is fixedly connected to the top side of the fixed support frame. The output end of the support lift is fixedly connected to the top side of the lifting plate.

[0007] Preferably, the top side of the lifting plate is fixedly connected to two sets of symmetrically distributed lifting columns, and the top side of the two sets of lifting columns is fixedly connected to a lifting support frame. The top side of the lifting support frame is fixedly connected to the bottom side of the supporting lifting machine, and the outer edges of both sides of the lifting plate are slidably connected to the opposite sides of the two sets of lifting columns.

[0008] Preferably, each of the positioning sliding columns has a rotating support plate rotatably connected to its bottom end on the side opposite to the lifting plate, and a lateral support shell is rotatably connected to the bottom side of each rotating support plate.

[0009] Preferably, each of the lateral support housings has a receiving slot on the side facing the positioning slide post, and a set of lateral support springs is fixedly connected to the inner wall of the receiving slot. One end of each set of lateral support springs is fixedly connected to one side of the corresponding support foot.

[0010] Preferably, a folded outer skin is fixedly connected to the outer edge of the support base on the side facing the lateral support shell, and an elastic outer skin is fixedly connected to one side of the folded outer skin. The inner side of the elastic outer skin is fixedly connected to the outer side of the corresponding lateral support shell.

[0011] Preferably, a protective side plate is fixedly connected to the outer edge of the fixed support frame, and multiple evenly distributed weight-reducing support beams are provided on the outer side of the protective side plate.

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

[0013] By using liftable positioning columns, the columns can be raised while the loader is in motion, without obstructing its normal operation. When the loader stops working, the columns are lowered to contact the ground, stabilizing the loader and preventing it from tipping over, thus making the construction process safer. Additionally, the support springs allow the bottom of each positioning column to conform to different ground heights, adapting to uneven terrain and improving construction stability.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] An anti-tipping device for a side-dump loader includes a loader cab 301. A fixed support frame 105 is fixedly connected to the outer side of the loader cab 301. Two sets of symmetrically distributed lifting sliding holes 107 are located on the top side of the fixed support frame 105. A positioning sliding post 201 is slidably connected between the inner walls of each lifting sliding hole 107. A support spring 204 is fixedly connected to the bottom end of each positioning sliding post 201. A support foot 205 is fixedly connected to the bottom end of each support spring 204. A lifting plate 104 is fixedly connected to the top side of all the positioning sliding posts 201. In this embodiment, a hydraulic bucket is provided on one side of the loader cab 301, while the fixed support frame 105 faces away from the side where the hydraulic bucket is located.

[0024] Two sets of symmetrically distributed lifting columns 103 are fixedly connected to the top side of the lifting plate 104. A lifting support frame 102 is fixedly connected to the top side of both sets of lifting columns 103. The top side of the lifting support frame 102 is fixedly connected to the bottom side of the support lift 101. The outer edges of both sides of the lifting plate 104 are slidably connected to the opposite sides of the two sets of lifting columns 103. A support lift 101 is fixedly connected to the top side of the fixed support frame 105. The output end of the support lift 101 is fixedly connected to the top side of the lifting plate 104. In this embodiment, the operation of the support lift 101 drives the lifting plate 104 to rise and fall, so that the bottom side of the support foot 205 is in close contact with the ground, thus supporting the loader.

[0025] Each positioning slide post 201 has a rotating support plate 208 rotatably connected to its bottom end on the side facing away from the lifting plate 104. Each rotating support plate 208 has a lateral support shell 207 rotatably connected to its bottom side. Each lateral support shell 207 has a receiving slot on the side facing the positioning slide post 201. A set of lateral support springs 206 are fixedly connected to the inner wall of the receiving slot. One end of each set of lateral support springs 206 is fixedly connected to one side of the corresponding support foot 205. A folded outer skin 202 is fixedly connected to the outer edge of the support foot 205 on the side facing away from the lateral support shell 207. An elastic outer skin 203 is fixedly connected to one side of the folded outer skin 202. The inner side of the elastic outer skin 203 is fixedly connected to the outer side of the corresponding lateral support shell 207. In this embodiment, as the support spring 204 is compressed, the lateral support shell 207 is pushed open, forming a triangular support structure, further enhancing the stability of the loader. The folding outer skin 202 can protect the support spring 204 and the support foot 205, and the elastic outer skin 203 will be stretched out when the lateral support shell 207 extends outward, thus playing a protective role.

[0026] A protective side plate 106 is fixedly connected to the outer edge of the fixed support frame 105. Multiple evenly distributed weight-reducing support beams are provided on the outer side of the protective side plate 106 to prevent impact damage to the anti-rollover device.

[0027] It should be noted that this utility model, as an anti-tipping device for a side-dump loader, utilizes the adjustable positioning slide column 201. During loader operation, the positioning slide column 201 is raised to allow for unimpeded movement. When the loader stops, the positioning slide column 201 is lowered to contact the ground, stabilizing the loader and preventing it from tipping over, thus enhancing safety during construction. Furthermore, the support spring 204 allows the bottom of each positioning slide column 201 to conform to different ground heights, adapting to uneven terrain and improving construction stability.
