Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools for tractor production, in particular to a trolley for transporting and storing fender top plates of wheeled tractors. Background Art

[0002] Wheeled tractor fender tops have an arc-shaped structure (for details, refer to Chinese Utility Model Patent Publication No. CN218858600U). On the assembly lines of wheeled tractors at Chinese tractor manufacturers, after painting, these fender tops need to be transported to the next assembly process. Currently, there are no dedicated transfer carts specifically designed for wheeled tractor fender tops on these assembly lines. Flatbed transfer carts are typically used for fender tops. While simple and versatile, these flatbed transfer carts present several challenges: First, they lack enclosures around them, making them easy to store but unsuitable for transporting across long distances between factories. Second, the fender tops are stored horizontally, stacked, and separated by protective materials. This can easily lead to bumps, deformation, and even scratches between the fenders during transport. Third, due to their large length-to-width ratio, flatbed transfer carts are difficult to use at workstations along the assembly line.

[0003] Based on this, it is very necessary to provide a highly convenient, highly stable, safe and reliable transport and storage trolley for wheeled tractor fender top plates. Utility Model Content

[0004] In order to solve the deficiencies in the prior art, the utility model provides a trolley for transporting and storing fender top plates of wheeled tractors. The trolley has strong versatility and can safely transport fender top plates of wheeled tractors on a tractor assembly line.

[0034] This embodiment discloses a trolley for transporting and storing wheeled tractor fender top plates. Figures 2 to 4 The trolley mainly includes a vehicle body, a support plate mechanism and a pressing and fixing mechanism. The trolley can realize the transportation and storage of the fender top plate 15. The various mechanisms are described in detail below.

[0035] <Car body>

[0036] The vehicle body is located at the bottom of the entire trolley, and the vehicle body includes a base plate 4 that plays a supporting role and driving wheels 8 located at the four corners of the lower end surface of the base plate 4. The driving wheels 8 include two universal wheels located on the left side and two fixed wheels located on the right side.

[0037] <Pallet mechanism>

[0038] The support mechanism includes two side supports respectively arranged on the left and right sides of the upper end surface of the base plate 4. The two side supports each include two vertical rods 1 fixed on the upper corners of the base plate 4, and several L-shaped plates 3 equidistantly connected between the two vertical rods 1. Several L-shaped plates 3 are arranged in sequence up and down. The inner side of each L-shaped plate 3 is provided with two support assemblies for placing the fender top plate 15 in front and back, that is, two rows of support assemblies are installed on the inner sides of the two side supports, so that a larger number of fender top plates 15 can be stored.

[0039] The pallet assembly includes a support steel plate 9 fixed to the L-shaped plate 3. The upper end surface of the support steel plate 9 is provided with a sponge support block 10, and the lower end surface is wrapped with a protective rubber. The sponge support block 10 and the protective rubber are used to protect the fender top plate 15 during transportation.

[0040] <Compression Fixing Mechanism>

[0041] The clamping and fixing mechanism includes a support column 5 provided in the middle of the base plate 4, a plurality of clamping and fixing assemblies 13 equidistantly installed on the support column 5 for clamping and fixing the fender top plate 15, and a driving assembly 12 acting on the clamping and fixing assembly 13 to swing it. The clamping and fixing assemblies 13 are provided in two rows, respectively provided on the front and rear sides of the support column 5, and each row contains a plurality of them. A plurality of earrings 16 are installed on the support column 5, and the number of earrings 16 is consistent with the number of support plate assemblies. U-shaped steels 17 are symmetrically provided below each earring 16 on the support column 5. The clamping and fixing assembly 13 includes a folding plate 1301 and a sponge strip 1302 adhered to the folding plate 1301. The driving assembly 12 includes a square tube 1202 hinged to the U-shaped steel 17, and a folding plate 1301 is provided on the end of the lower end face of the square tube 1202 away from the support column 5, and a gas spring 1201 is provided on the upper end face of the square tube 1202, one end of the gas spring 1201 is connected to the earring 16, and the other end is connected to the square tube 1202; the gas spring 1201 can adjust the clamping and fixing assembly 13 between a release position and a restriction position, and the clamping and fixing assembly 13 is in the release position, the gas spring 1201 is in the shortest working position, and the trolley is in an empty state; the clamping and fixing assembly 13 is in the restriction position, the gas spring 1201 is in the longest working position, and the clamping and fixing assembly 13 clamps and fixes the fender top plate 15.

[0042] When the fender top plate 15 is placed on the trolley, the pressing and fixing assembly 13 can press and fix the fender top plate 15, thereby preventing the fender top plate 15 from sliding during long-distance transportation. In addition, the sponge strip 1302 directly contacts the fender top plate 15, which can also prevent the fender top plate 15 from being scratched.

[0043] Specifically, the gas spring 1201 is a compression gas spring.

[0044] Specifically, please refer to Figure 6 The earring 16 has a U-shaped structure with a convex edge, and two gas springs 1201 can be connected to one earring 16 at the same time.

[0045] Preferably, the side support frame and the support column 5 are connected via a U-shaped rod 14, which increases the firmness of the trolley.

[0046] Preferably, limiting columns 6 are provided in parallel on both the front and rear sides of the support column 5 , and a protective tube is provided on the outer sleeve of the limiting column 6 for limiting the fender top plate 15 to prevent the fender top plate 15 from rubbing against the support column 5 and thereby scratching the fender top plate 15 .

[0047] It should be noted that to facilitate the transport of the trolley, handles 2 are provided on the outside of the side supports. These handles are made of bent seamless steel pipes and are approximately 750mm above the ground, facilitating manual transport at the assembly site. Forklift stops are provided on the lower end of the base plate 4, with a center spacing of 700mm to facilitate forklift transport and stacking at the assembly site.

[0048] Among them, the bottom plate 4, the vertical rod 1, and the U-shaped rod 14 are all made of angle steel, which can effectively reduce the weight of the trolley itself and improve the efficiency of manual transportation.

[0049] Example 2

[0050] In this embodiment, stacking cups 11 are provided at the top of the four vertical rods 1. After the stacking cups 11 are installed, it is convenient for the trolleys to be stacked and stored. Figure 1 and Figure 5 The stacking foot cup 11 is composed of a bent round steel 1101 and a bent plate 1102. The bent plate 1101 is bent three times. The bent round steel 1101 is bent 90° and then welded to the opening at the upper end of the bent plate 1102.

[0051] In summary, the trolley in the utility model has a simple structure, is suitable for the transportation and storage of the fender top plate of the wheeled tractor, is easy to use, is not easy to bump into and damage the loaded objects, and is convenient for various transportation methods.

[0052] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any equivalent changes or modifications made according to the essence of the present invention should be included in the scope of protection of the present invention.
