Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fence car, especially to a light truck aluminum alloy fence car. BACKGROUND

[0002] The fence car used in the market basically has four fences on the outside of the square bottom plate, wherein the fence at the front end is fixedly installed and close to the position of the vehicle head, and the fences at the left and right sides and the rear end are hingedly installed and can be turned down to be laid down to realize loading and unloading goods, etc. Traditionally, the fence car is a car with a steel structure, which is heavy and needs to be coated with paint to prevent rust, etc. Therefore, an aluminum alloy car is gradually pushed out, which has more advantages than the traditional steel structure car, and the car is lighter in weight, which is about 40% lighter than the steel car of the same size, saves 0.42 liters of fuel per 100 kilometers, and is more energy-saving and environment-friendly. Data shows that about 13.5kwh of electricity is needed to extract 1kg of raw aluminum, but in automobile manufacturing, 1kg of aluminum material can replace 3kg of steel material, and the saving of 1kg of material in the use cycle of the car can save 0.7kg of fuel, which is equivalent to saving 12800kwh of electricity, reducing carbon dioxide emissions by about 2670kg, and nearly 100 times of energy saving. In addition, under the same specifications, the aluminum alloy car is lighter than the steel structure car, and the load capacity under full load is larger than that of the steel structure car, so the utilization rate of the load is effectively improved.

[0003] However, although the aluminum alloy carriage has the advantages of light weight, environmental protection, and fuel saving, there are still some problems, as follows: (1) when the left and right side plates of the carriage need to be flipped down from the vertical state for loading and unloading, the whole left and right side plates are directly flipped down; such structure and loading and unloading method will cause some goods in the carriage to be in an unobstructed state during the process, which is prone to falling due to accidental circumstances (such as not being fixed well, the two sides of the carriage being unbalanced and skewed, etc.), causing damage to the goods or packaging, and even personal safety hazards if the loading and unloading personnel are hit; especially the goods near the side of the carriage have a higher risk of not being obstructed by the side plate.(2) The traditional side plate carriage structure is basically composed of a bottom plate combined with a side plate around it, and basically does not have a carriage rear lever, which will cause the rear of the carriage to lack a binding position, making it inconvenient to bind and fix larger goods, and unable to effectively fix the goods in the carriage, which may cause the goods to fall or overturn during transportation.(3) The traditional side plate carriage has many parts welded or riveted together, which makes maintenance and repair very inconvenient when parts are damaged, and some parts cannot be replaced, only the whole carriage or the damaged part can be replaced, causing installation and replacement trouble and complexity, long time consumption, and high replacement cost.(4) The traditional steel structure carriage will quickly oxidize and rust after the steel paint layer falls off, seriously affecting the service life, and often needs to be painted and welded for maintenance, which has high maintenance cost and poor corrosion resistance. Although the improved existing aluminum alloy carriage has the characteristics of corrosion resistance and rust resistance, the surface of the aluminum alloy carriage does not have any oxidation surface treatment or a thin oxidation layer (generally 0.5-4um thick) formed after oxidation treatment, which cannot further improve the surface hardness of the aluminum alloy and the wear resistance, and has the disadvantages of easy deformation, short service life, and poor wear resistance.

[0004] Therefore, it is necessary to improve the structure of the existing carriage to solve the problems of the prior art and develop a light aluminum alloy side plate carriage structure. SUMMARY

In addition, a rear pole can be movably installed on the truck according to needs, which serves as a fixing point for binding ropes to bind goods and also serves as a support for fixing the rear goods, thereby improving the loading stability of the rear goods. When the rear pole is not needed, it can be easily and quickly disassembled by loosening the locking nut. Finally, the components of the truck are independently modularly designed and assembled by bolt connection. If a component is damaged, it can be individually disassembled and replaced, which is convenient for maintenance and repair and reduces maintenance costs. The truck accessories are treated with a silver-white oxidation surface treatment process to form an oxide film layer with a thickness of 8-10 um, high surface hardness and strong corrosion resistance, which basically eliminates maintenance costs and greatly improves the service life.

[0028] Example 1

[0029] The aluminum alloy panel truck carriage described in this example 1, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , includes an aluminum alloy bottom plate 1, an aluminum alloy front plate 2 and an aluminum alloy rear plate 3 installed at the front end and rear end of the aluminum alloy bottom plate respectively, an aluminum alloy left side plate 4 and an aluminum alloy right side plate 5 installed at the left side and right side of the aluminum alloy bottom plate respectively, and an aluminum alloy carriage rear bar piece 6 installed vertically on the aluminum alloy bottom plate near the aluminum alloy rear plate; the aluminum alloy left side plate includes an aluminum alloy left side post 7 installed vertically on the left side of the aluminum alloy bottom plate, an aluminum alloy left side movable left plate 8 and an aluminum alloy left side movable right plate 9 formed in hinged installation with the left side of the aluminum alloy bottom plate and respectively formed in left and right clamping movable installation with the aluminum alloy left side post; the aluminum alloy right side plate includes an aluminum alloy right side post 10 installed vertically on the right side of the aluminum alloy bottom plate, an aluminum alloy right side movable left plate 11 and an aluminum alloy right side movable right plate 12 formed in hinged installation with the right side of the aluminum alloy bottom plate and respectively formed in left and right clamping movable installation with the aluminum alloy right side post.

[0030] The light truck aluminum alloy panel truck compartment is composed of a bottom plate and front, rear, left and right plates, and the aluminum alloy panel truck compartment is lighter than the same specification truck compartment. The traditional steel structure truck compartment and the existing aluminum alloy truck compartment are basically not equipped with a truck compartment rear pole, which causes the lack of a rope fixing point when loading goods, and the use is inconvenient. The light truck aluminum alloy panel truck compartment is additionally provided with an aluminum alloy truck compartment rear pole which can be used as a rope fixing point, can realize the tight fixing of the loaded goods, and can be used as a support for the rear goods, thereby achieving the effect of stable transportation of the loaded goods during transportation. The aluminum alloy left and right side plates are designed as two-section movable plates, and the movable lock buckles are installed between the two-section movable plates through aluminum alloy uprights, so that the movable plates corresponding to the goods to be loaded and unloaded can be opened, and the movable plates on the same side which do not need to load and unload goods do not need to be opened, thereby ensuring that the goods without opened movable plates will not accidentally slide off and the like. The aluminum alloy uprights are directly inserted into the side positions of the aluminum alloy bottom plate and connected and installed by quick connecting bolts, thereby facilitating disassembly; when the two movable plates on the same side need to be completely opened for unobstructed loading and unloading of goods, the aluminum alloy uprights can be directly disassembled to achieve the purpose of removing the aluminum alloy uprights, thereby facilitating loading and unloading of goods.

[0031] In the embodiment 1, the aluminum alloy truck compartment rear pole includes a rear pole left mounting seat 14 and a rear pole right mounting seat 15 which are fixedly installed on the left and right sides of the top of the aluminum alloy bottom plate, and a rear pole 16 which is installed between the rear pole left mounting seat and the rear pole right mounting seat; the rear pole is inserted into the rear pole left mounting seat and the rear pole right mounting seat respectively and is movably locked and installed by lock bolts 17; and the top of the rear pole is provided with a rear pole protruding column 18 which protrudes upward. The rear pole left mounting seat and the rear pole right mounting seat are fixedly installed on the side positions of the aluminum alloy bottom plate and do not protrude too high, so that when the rear pole is not installed, the loading of goods is not hindered, and the loading of goods is facilitated. The rear pole is movably and quickly installed by the lock bolts (traditional lock bolt structure with a hand wheel), the rear pole is quickly and conveniently installed and disassembled, the bottom end of the rear pole is directly inserted into the corresponding mounting seat and is manually locked by the lock bolt, so that the installation of the rear pole is achieved, and the rear pole is disassembled and removed from the corresponding mounting seat by loosening the lock bolt. The rear pole is similar to an inverted U-shaped structure, and has a horizontal beam and a vertical beam at the middle and upper portions for the end of the rope to be tightly bound, and the rear pole protruding column is additionally provided on the top of the rear pole to serve as a fixing point for the rope. When the height of the loaded goods is basically the same as or higher than the top of the rear pole, the rear pole protruding column can be used as the highest point for the rope to be bound, thereby facilitating the binding of the high goods.

[0032] In the embodiment 1, as Figure 6As shown, the left and right sides of the aluminum alloy left side post and the aluminum alloy right side post are provided with a lock hook 19, and the aluminum alloy left side movable left plate, the aluminum alloy left side movable right plate, the aluminum alloy right side movable left plate and the aluminum alloy right side movable right plate are provided with a movable lock catch handle 20 which is movably locked and mounted with the corresponding lock hook. The aluminum alloy post is a detachable quick mounting structure, which can be removed when unloading and loading, facilitating loading and unloading.

In addition, the rear pole can be installed on the carriage as needed, which is used as a binding point for binding goods and can also be used to support and fix the rear goods, thereby improving the loading stability of the rear goods of the carriage. When the rear pole is not needed, the locking nut is loosened to disassemble the rear pole, which is convenient and fast. Finally, the components of the carriage are all modularly designed and assembled by the bolt connection process, if a component is damaged, it can be individually disassembled and replaced, which is convenient for maintenance and repair and has low maintenance cost. The carriage accessories are subjected to a silver-white oxidation surface treatment process to form an oxide film layer, the thickness of the oxide film layer is 8-10um, the surface hardness is high, the corrosion resistance is strong, the maintenance cost can be basically saved, and the service life can be greatly improved.
