[0002] At present, traditional dump truck boxes are mostly made of metal materials. Although the dump truck boxes made of metal materials have the characteristics of high strength, good durability, and long service life, with the progress of technology and the improvement of environmental awareness, some non-negligible disadvantages of traditional metal material boxes have gradually emerged. For example, due to the large density of the metal material, the overall weight of the box is relatively heavy, which not only affects the fuel economy of the vehicle, but also limits the load capacity of the vehicle and affects the transportation efficiency. At the same time, in a harsh transportation environment, the box often needs to withstand the erosion of various corrosive media, and metal materials are often difficult to resist this erosion for a long time, resulting in a shortened service life of the box and an increase in the later maintenance cost, etc.

[0038] Embodiment 1:

[0039] The present invention provides a tipping truck box made of basalt fiber composite material.

[0040] In an embodiment of the present invention, a tipping truck box made of basalt fiber composite material includes a bottom plate 1, a front baffle 2, a rear baffle 3, and two side plates 4. A box door is installed on the rear baffle 3 in a limited and movable manner. The front baffle 2 and the rear baffle 3 are respectively detachably installed on opposite sides of the bottom plate 1. Slots 5 are respectively formed on the front baffle 2 and the rear baffle 3. The two ends of the two side plates 4 are respectively inserted into the slots 5 and detachably connected to the front baffle 2 and the rear baffle 3. And on the front baffle 2 and the rear baffle 3, there are provided support plates 6 for supporting the two side plates 4. The bottoms of the two side plates 4 are detachably connected to the bottom plate 1.

[0041] Specifically, as Figures 1 to 3 shown, in a tipping truck box made of basalt fiber composite material of the present invention, since the front baffle 2 and the rear baffle 3 are respectively detachably installed on the front and rear sides of the bottom plate 1, the detachable installation manner of the front baffle 2 and the rear baffle 3 with the bottom plate 1 can be a threaded connection, that is, bolt holes are preset on the bottom plate 1, the front baffle 2, and the rear baffle 3, and the three are tightly connected by high-strength bolts. The bolt connection has the characteristics of reliable connection and easy disassembly, so as to facilitate the disassembly and assembly of the bottom plate 1, the front baffle 2, and the rear baffle 3.

[0042] Further, since slots 5 are respectively formed on the front baffle 2 and the rear baffle 3, the front and rear ends of the two side plates 4 are respectively inserted into the slots 5 on the front baffle 2 and the rear baffle 3. Thus, not only can the two side plates 4 and the bottom plate 1, the front baffle 2 and the rear baffle 3 enclose a device space for placing materials, but also the two side plates 4 can be prevented from disengaging from the front baffle 2 and the rear baffle 3 in the left and right directions, improving the connection tightness. The structural design is simple and reasonable. At the same time, the detachable installation method of the front and rear ends of the two side plates 4 with the front baffle 2 and the rear baffle 3 can also be threaded connection, that is, by presetting bolt holes on the two side plates 4 and using high-strength bolts to tightly connect the two side plates 4 with the front baffle 2 and the rear baffle 3, thereby ensuring the connection stability and reliability of the two side plates 4 with the front baffle 2 and the rear baffle 3. It can be understood that since the front baffle 2 and the rear baffle 3 are provided with supporting plates 6 for supporting the two side plates 4, on the one hand, the two side plates 4 can be supported and limited in the up and down direction by the supporting plates 6. Thus, when the staff installs the side plates 4, after inserting them into the slots 5, they only need to complete the subsequent fastening operation (such as installing bolts), which not only improves the installation convenience of the two side plates 4, is conducive to assembly, but also reduces the installation difficulty of the side plates 4 and improves the overall assembly efficiency of the carriage. On the other hand, the supporting plates 6 can also provide additional support for the two side plates 4, thereby improving the installation stability of the side plates 4 and the overall structural strength of the carriage and enhancing the durability. In addition, after the two side plates 4 are connected to the front baffle 2 and the rear baffle 3, at this time, the staff can detachably connect the bottoms of the two side plates 4 to the bottom plate 1. The detachable installation method of the two side plates 4 and the bottom plate 1 can be threaded connection. The threaded connection is convenient for disassembly and assembly, and specifically, high-strength bolts can be used to ensure the connection stability and reliability between the bottoms of the two side plates 4 and the bottom plate 1, further improving the overall structural strength of the carriage.

[0043] It is worth noting that since a box door is installed on the rear baffle 3 in a limited and movable manner, the limited and movable installation method of the box door and the rear baffle 3 can be pin hinge, and at the same time, it is cooperated with a driving component (such as a hydraulic cylinder) to drive the box door to rotate relative to the rear baffle 3, so that the box door can be opened or closed and the unloading operation can be completed thereby.

[0044] It should be noted that in the dump truck box of a basalt fiber composite material of the present invention, the bottom plate 1, the front baffle 2, the rear baffle 3 and the two side plates 4 are all made of basalt fiber composite material parts. Specifically, the main materials of the basalt fiber composite material include 13μm basalt continuous fiber and epoxy resin, wherein the fiber content is 65% and the epoxy resin content is 30%; the auxiliary materials include fillers, hardware, etc., so that the comprehensive density of the basalt fiber composite material is between 1.85 and 2.45, only 1 / 4 to 1 / 3 of the steel plate material (density is 7.8). Therefore, in the present invention, since each plate member uses basalt fiber composite material parts, the weight is greatly reduced, and the weight reduction compared with the traditional metal material box is more than 1 / 3, thereby improving the fuel efficiency and load capacity of the vehicle; at the same time, the high-strength characteristics of the basalt fiber composite material also ensure the stability and durability of the present invention when bearing heavy loads and complex working conditions. In addition, the basalt fiber composite material also has good corrosion resistance, so that the present invention can resist the erosion of various corrosive media such as acids, alkalis, and salts in a harsh transportation environment, thereby greatly extending the service life.

[0045] In an embodiment, the bottom plate 1 includes a plurality of base plates 7 and connecting plates 8, and the plurality of base plates 7 are arranged in sequence along the extending direction of the side plate 4; first protrusions 9 are respectively formed on opposite sides of the base plate 7, and both of the two first protrusions 9 extend along the width direction of the base plate 7, and any two adjacent first protrusions 9 are in contact with each other and form a clamping portion 10, and a first clamping groove 11 for limit clamping with the clamping portion 10 is formed on the connecting plate 8.

[0046] Specifically, as Figures 1 to 4 shown, since the plurality of base plates 7 in the bottom plate 1 are arranged in sequence in the front-rear direction, and first protrusions 9 are respectively formed on the front and rear sides of the plurality of base plates 7, so that the first protrusions 9 on the front and rear sides of two adjacent base plates 7 can be in contact with each other and thereby form a clamping portion 10 for clamping and cooperating with the first clamping groove 11, and the structural design is simple and reasonable. Further, when the staff assembles the plurality of base plates 7, since both of the two first protrusions 9 extend in the left-right direction, by installing the connecting plate 8 between two adjacent base plates 7, that is, sliding the connecting plate 8 in the left-right direction and making the first clamping groove 11 on the connecting plate 8 be in limit clamping with the clamping portion 10, the two adjacent base plates 7 can be stably connected. Repeating the above steps can realize the overall assembly of the bottom plate 1. It not only has simple operation, simplifies the assembly process of the bottom plate 1, but also improves the disassembly and assembly convenience between the plurality of base plates 7, which is beneficial to replacement and maintenance, and ensures the connection stability and reliability between the plurality of base plates 7 through the clamping cooperation of the clamping portion 10 and the first clamping groove 11. It can be understood that compared with the bottom plate 1 with an integral structure in the existing technology for the box, the bottom plate 1 of the present invention can be disassembled into a plurality of base plates 7, thereby reducing the space occupied by the bottom plate 1, which is beneficial to transportation and handling.

[0047] In one embodiment, second protrusions 12 are respectively formed on two connecting plates 8 close to the front baffle 2 and the rear baffle 3. Both of the two second protrusions 12 extend along the width direction of the connecting plate 8. Second card slots 13 for limiting and clamping with the second protrusions 12 are respectively formed on the front baffle 2 and the rear baffle 3. Specifically, as Figure 1 and Figure 6 shown, since the second protrusions 12 extend in the left - right direction, it enables the staff to slide - mount the front baffle 2 and the rear baffle 3 in the left - right direction respectively onto the two connecting plates 8 at the front end and the rear end of the bottom plate 1. At this time, the second card slots 13 are in clamping fit with the second protrusions 12, so as to achieve a firm connection between the front baffle 2, the rear baffle 3 and the bottom plate 1. The structural design is simple and reasonable.

[0048] In one embodiment, as Figure 4 and Figure 6 shown, the shapes and sizes of the clamping portion 10 and the first card slot 11, and the second protrusion 12 and the second card slot 13 are the same and match each other. The first card slot 11 and the second card slot 13 are respectively any one of a T - shaped groove, a dovetail groove or a circular groove, so as to form a good clamping effect on the clamping portion 10 and the second protrusion 12, and ensure the firmness and reliability of the connection between each plate member. It should be noted that the connecting plate 8 can also be made of a basalt fiber composite material, and local strengthening treatment can be carried out on both the first protrusion 9 and the second protrusion 12, so as to enhance the bearing capacity of the connecting plate 8, the first protrusion 9 and the second protrusion 12, and ensure the firm connection between each plate member. In addition, the slot openings at both left and right ends of the first card slot 11 and the second card slot 13 are both arranged to expand outwards, so that it is convenient for the staff to smoothly insert the clamping portion 10 and the second protrusion 12 into the first card slot 11 and the second card slot 13, which is beneficial to installation.

[0049] In one embodiment, the slot opening of the slot 5 is arranged corresponding to the slot openings of the first card slot 11 and the second card slot 13. Plugging portions 14 are respectively formed at both ends of the two side plates 4. The plugging portions 14 are in plugging fit with the slot 5 and are detachably connected to the front baffle 2 and the rear baffle 3 through a plurality of fasteners. And a notch groove 15 for the support plate 6 to extend into is formed at the bottom end of the plugging portion 14; A shielding portion 16 for covering the slot openings of the first card slot 11 and the second card slot 13 is formed at the bottom of the two side plates 4. Locking members are detachably installed on the shielding portion 16 corresponding to the positions of a plurality of connecting plates 8.

[0050] Specifically, as Figures 1 to 4As shown, since the notches of the slot 5 correspond to the notches of the first card slot 11 and the second card slot 13, when the staff installs the side plate 4, the pre-positioning of the side plate 4 can be realized by inserting the insertion part 14 of the side plate 4 into the slot 5, effectively preventing the side from moving or dislocating relative to the bottom plate 1 in the left-right direction; at the same time, the fasteners can be high-strength bolts in the prior art, and the insertion part 14 is detachably connected to the front baffle 2 and the rear baffle 3 by a plurality of fasteners, so as to ensure the connection stability between the side plate 4 and the front baffle 2 and the rear baffle 3; moreover, when the staff installs the fasteners, at this time, the side plate 4 overlaps on the support plate 6 and the support plate 6 supports and limits the side plate 4, thereby effectively preventing the support plate 6 from falling downward and disengaging from the slot 5, and by opening a notch groove 15 at the bottom end of the insertion part 14 for the support plate 6 to extend into, not only can the contact area between the support plate 6 and the side plate 4 be increased, the abutting tightness between the support plate 6 and the side plate 4 be improved, but also the structural strength between the side plate 4 and the front baffle 2 and the rear baffle 3 be enhanced.

[0051] It can be understood that since a shielding part 16 is formed at the bottom of the side plate 4, when the side plate 4 is firmly connected to the front baffle 2 and the rear baffle 3 by fasteners, at this time, the shielding part 16 at the bottom of the side plate 4 can cover the two end notches of the first card slot 11 and the second card slot 13 in the left-right direction, thereby effectively preventing the connecting plate 8 from moving relative to the base plate 7 in the left-right direction and disengaging from the base plate 7, ensuring the connection effect between the connecting plate 8 and the base plate 7, and the structural design is simple and reasonable; at the same time, by installing locking parts at the positions corresponding to a plurality of connecting plates 8 on the shielding part 16, the locking parts can also be high-strength bolts in the prior art, which can not only improve the connection stability between the side plate 4 and the bottom plate 1, but also further increase the connection strength between the plate members, and the use is reliable.

[0052] In an embodiment, it further includes a top plate 17 for covering the inner cavity of the carriage. The top plate 17 includes a fixed plate 18 and two movable plates 19. The two opposite sides of the fixed plate 18 are detachably connected to the two side plates 4 respectively, and the two movable plates 19 are installed on the fixed plate 18 in a limited and movable manner along the extending direction of the bottom plate 1 by a driving member. Specifically, as Figure 8 shown, by providing the top plate 17 at the top of the carriage, the inner cavity of the carriage can be covered, which can not only protect the materials and goods in the carriage from wind and rain, keep them dry and clean, but also effectively prevent the goods from completely pouring out of the carriage in case of accidental accidents such as vehicle rollover, thereby effectively reducing the loss of goods, reducing the harm of the accident to personnel and the environment, improving the use safety, and the top plate 17 can support the two side plates 4, thereby improving the ability of the side plates 4 to withstand left-right impact loads and the overall structural strength of the carriage, and prolonging the service life of the present invention.

[0053] Furthermore, as Figure 8and Figure 10 As shown, since the left and right sides of the fixed plate 18 in the top plate 17 are detachably connected to the two side plates 4 respectively, the detachable connection method can be threaded connection, so that not only the stable installation of the fixed plate 18 can be realized, but also the disassembly and assembly of the top plate 17 are convenient and beneficial for maintenance; at the same time, combined with Figure 7 it can be known that since the two movable plates 19 are installed on the fixed plate 18 in a limited movement manner along the extension direction of the bottom plate 1 (i.e., the front-back direction) by a driving member, the driving member can be a hydraulic cylinder in the prior art, so that the two movable plates 19 can slide relative to the fixed plate 18 in the front-back direction, and the structural design is simple and reasonable. It can be understood that when loading goods into the carriage, the movable plate 19 at the front end is driven by the driving member to move backward, so that the inner cavity of the carriage can be opened and the goods can be loaded; similarly, when the inner space near the front end of the carriage is full of goods, at this time, the movable plate 19 at the rear end can be driven by the driving member to move forward, and the goods can be loaded into the inner space near the rear end of the carriage, so as to ensure the full utilization of the inner space of the carriage and improve the transportation efficiency of the goods. In addition, it should be noted that after the present invention is installed on the vehicle and during the actual transportation process, the two movable plates 19 are always in a closed state under the action of the driving member, that is, covering the inner cavity of the carriage, so as to ensure the covering effect on the goods.

[0054] It is worth noting that the fixed plate 18 and the two movable plates 19 can both be made of basalt fiber composite materials, so as to ensure the use effects of the fixed plate 18 and the two movable plates 19, so that the fixed plate 18 and the two movable plates 19 can bear large loads and are not easily deformed or damaged, and thereby improve the support stability of the side plate 4, and are beneficial to reducing the overall weight of the carriage and improving the fuel economy and driving performance of the vehicle.

[0055] In an embodiment, a limiting step 20 is formed at the bottom of the fixed plate 18, and a plurality of mounting holes are evenly and spacedly formed on the limiting step 20 along the extension direction of the bottom plate 1; grooves 21 for sliding contact and cooperation with the fixed plate 18 are formed on the bottom surfaces of the two movable plates 19, limiting grooves 22 are formed on both sides of the two movable plates 19 along their respective extension directions, and limiting columns 23 for extending into the limiting grooves 22 are spacedly arranged on the side walls of the fixed plate 18.

[0056] Specifically, as Figure 8 、 Figure 10 and Figure 11As shown, since a limiting step 20 is formed in the front-back direction at the bottom of the fixing plate 18, and a plurality of mounting holes are evenly and spacedly formed in the side wall of the limiting step 20 in the front-back direction, so that the staff can pass a plurality of high-strength bolts through the plurality of mounting holes one by one and threadedly connect them to the side plate 4 when installing the fixing plate 18, thereby realizing the multi-point installation of the fixing plate 18 and ensuring the installation stability of the fixing plate 18 on the side plate 4. Further, by providing grooves 21 on the bottom surfaces of the two movable plates 19, the two movable plates 19 can slide along the extending direction of the fixing plate 18 (i.e., the front-back direction) under the action of the driving member, improving the sliding stability of the movable plates 19; at the same time, during the sliding process of the movable plates 19, the top surfaces of the two side walls of the groove 21 are in contact with the limiting step 20, and at this time the limiting step 20 can play a limiting role in the up-down direction for the movable plates 19, further improving the smoothness of the movable plates 19 when sliding and switching; and, the side walls of the two movable plates 19 can be in close contact with the two side plates 4, thereby ensuring a stable supporting effect on the two side plates 4, and the structural design is simple and reasonable. It can be understood that since limiting grooves 22 are respectively formed in the front-back direction on both sides of the two movable plates 19, and limiting posts 23 for extending into the limiting grooves 22 are provided on the fixing plate 18, the plug-in fit between the limiting posts 23 and the limiting grooves 22 can effectively prevent the movable plates 19 from moving upward and separating from the fixing plate 18, ensuring the sliding stability and installation reliability of the movable plates 19.

[0057] In one embodiment, as Figure 9 and Figure 10 shown, inclined plates 24 are respectively detachably mounted on the top surfaces of the two movable plates 19. Specifically, the detachable mounting manner of the inclined plates 24 and the movable plates 19 can adopt threaded connection, so as to facilitate the disassembly, assembly and replacement of the inclined plates 24. Further, by providing the inclined plates 24 on the movable plates 19, the generation of accumulated water on the movable plates 19 can be effectively prevented, improving the shielding and protection effect on the goods. It is worth noting that when the staff installs the inclined plates 24, the inclined plates 24 can be installed in a front-back inclined state, so that the goods can naturally slide into the carriage under the action of the inclined plates 24 during loading, facilitating the loading of the goods.

[0058] In one embodiment, a support frame 25 is provided on the bottom surface of the bottom plate 1. The support frame 25 includes two main longitudinal beams 26 and a plurality of cross beams 27. The two main longitudinal beams 26 are spaced apart and extend towards the front baffle 2 and the rear baffle 3. The plurality of cross beams 27 are evenly and spacedly clamped on the two main longitudinal beams 26 along the extending direction of the bottom plate 1. Specifically, in combination with Figure 1 , Figure 5 and Figure 7It can be seen that since the two main longitudinal beams 26 in the support frame 25 are arranged at intervals in the left-right direction and extend towards the front baffle 2 and the rear baffle 3 (i.e., the front-rear direction), the main longitudinal support for the bottom plate 1 and the other plate members can be provided thereby; meanwhile, a plurality of cross beams 27 are evenly and spacedly clamped on the two main longitudinal beams 26 in the front-rear direction, so that a stable grid-like structure can be formed, and sufficient lateral support can be provided for the bottom plate 1 and the other plate members, which can not only effectively prevent the carriage from deforming or being damaged, but also improve the bearing capacity, and the structural design is simple and reasonable. It should be noted that the bottom plate 1 can be firmly connected to the two main longitudinal beams 26 and a plurality of cross beams 27 through high-strength threads.

[0059] In one embodiment, the support frame 25 further includes a plurality of secondary longitudinal beams 28, and the plurality of secondary longitudinal beams 28 are arranged corresponding to the positions of the two side plates 4; hinge plates 29 are respectively arranged at the positions close to the rear baffle 3 on both sides of the two main longitudinal beams 26; a hinge seat 30 is arranged on the front baffle 2. Specifically, as Figure 1 , Figure 5 and Figure 7 shown, by arranging a plurality of secondary longitudinal beams 28 corresponding to the positions of the two side plates 4, additional support can be provided for the two side plates 4, and a frame structure can be formed between the secondary longitudinal beams 28, the main longitudinal beams 26 and the cross beams 27, thereby enhancing the structural strength of the support frame 25, enabling the present invention to bear greater weight and pressure. By hinging the hinge plate 29 to the vehicle and the hinge seat 30 to an external lifting mechanism, the present invention can be easily turned over for unloading.

[0060] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
