Description

Technical Field

[0001] The utility model relates to the technical field of winches, in particular to a winch loading vehicle capable of preventing a bottom shaft from tilting. Background Art

[0002] In the soda ash production process, raw materials such as limestone and sodium chloride are mixed in a specific proportion and fed into a reactor for a chemical reaction. The hoist's loading trolley is primarily used to lift the raw materials to a higher position for subsequent processing. This is accomplished through a system of wire ropes and pulleys. The loading trolley is a mobile platform mounted on the hoist frame, used to load the raw materials. When the hoist is operating, the wire rope is retracted and extended, driving the loading trolley up and down along the track, thereby lifting and conveying the materials.

[0003] For safe production, loading carts must be strong enough to prevent deformation or breakage due to stress during material transport. Therefore, the wheels of loading carts are typically connected to a bottom axle located under the cart. The strength of the bottom axle ensures consistent wheel spacing, allowing for stable operation along the track. However, due to the high dust levels on site, loading carts require regular maintenance, requiring the bottom axle to be disassembled. Therefore, the bottom axle cannot be directly welded to the cart bottom and is typically connected detachably via bolts.

[0004] During long-term operation, the bolts will become loose to a certain extent, which will cause the bottom shaft to tilt. The tilted bottom shaft may cause the two wheels on it to be stuck in the track, causing the loading car to be stuck in the winch frame, which brings inconvenience to maintenance and processing and poses a safety hazard. Utility Model Content

[0005] The purpose of the utility model is to provide a winch loading car that prevents the bottom shaft from tilting, which can improve the stability of the bottom shaft connected to the bottom surface of the loading car, avoid it from tilting and causing the wheels to get stuck in the track, and improve the stability of the loading car's operation.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a winch loading car that prevents the bottom shaft from skewing, including a car body, and at least two bottom shafts are detachably connected to the bottom surface of the car body along its width direction, and the bottom shaft is a square shaft, and the bottom surface of the car body is provided with a limit plate corresponding to each square shaft, and the limit plate is provided with a limit opening, and the square shaft is slidably connected in the limit opening and is detachably connected to the bottom surface of the car body through a fixing member.

[0007] A further improvement of the present invention is that a vertical plate is provided on the bottom surface of the vehicle body along its width direction, the fixing member is a bolt, and the square shaft is connected to one surface of the vertical plate by the bolt.

[0008] A further improvement of the present invention is that there are two limit plates corresponding to each square axis, which are respectively located on both sides of the vertical plate.

[0009] A further improvement of the present invention is that a plurality of first screw holes are provided through the square shaft, and second screw holes corresponding to the first screw holes are provided on the vertical plate, and bolts are threadedly connected to the first screw holes and locked by nuts.

[0010] A further improvement of the present invention is that the vertical plate and the limiting plate are welded to the vehicle body.

[0011] A further improvement of the present invention is that the vertical plate and the limiting plate are an integrated I-shaped plate.

[0012] A further improvement of the present invention is that both ends of the square shaft are detachably and rotatably connected to wheels.

[0013] The beneficial effects of the present invention are:

[0014] The utility model provides a limit plate on the bottom surface of the loading car, and cooperates with the bottom shaft through the limit opening on the limit plate. Even if the bolts are loosened, the bottom shaft can only move axially to a certain extent (after axial movement, the two wheels on the bottom shaft can still move along the track) without skewing, avoiding the situation where the distance between the two sides of the wheel and the track is reduced due to skewing of the bottom shaft and the wheel is stuck in the track, which can improve the stability of the bottom shaft connected to the bottom surface of the loading car and the stability of the loading car operation.

[0015] The utility model provides a vertical plate on the bottom surface of the loading car, and the square shaft is detachably connected to the vertical plate by bolts, which is convenient for maintenance and repair. The vertical plate can strengthen the bottom surface of the loading car and improve its load capacity.

[0016] The vertical plate and the limiting plate of the utility model are an integrated I-shaped plate, which improves the overall strength and is conducive to the stable operation of the loading vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom surface of the vehicle body 1 is detachably connected to at least two bottom shafts along its width direction. The bottom shafts are square shafts 2. The bottom surface of the vehicle body 1 is provided with a limiting plate 3 corresponding to each square shaft 2. The limiting plate 3 is provided with a limiting opening 4. The square shaft 2 is slidably connected in the limiting opening 4 and is detachably connected to the bottom surface of the vehicle body 1 through a fixing member 5.
