Description

Technical Field

[0001] The invention relates to the technical field of dump trucks, and in particular to a dump truck body made of basalt fiber composite material. Background Art

[0002] At present, traditional dump truck bodies are mostly made of metal materials. Although dump truck bodies made of metal materials have the characteristics of high strength, good durability and long service life, with the advancement of science and technology and the improvement of environmental awareness, traditional metal body boxes have gradually exposed some shortcomings that cannot be ignored. For example, the metal body box has a high material density, which makes its overall weight heavy, which not only affects the fuel economy of the vehicle, but also limits the vehicle's load capacity and affects the transportation efficiency; at the same time, in harsh transportation environments, the body box often needs to withstand the erosion of various corrosive media, and metal materials are often difficult to resist such erosion for a long time, which shortens the service life of the body box and increases the subsequent maintenance costs.

[0003] Based on this, basalt fiber composite materials, as a new type of high-performance material, have received extensive attention in the field of automobile manufacturing, especially in the manufacturing of dump truck boxes in recent years. This material is made of basalt ore through a special process and has the characteristics of light weight, high strength, and corrosion resistance, which has brought changes to the manufacturing of dump truck boxes. However, due to the non-metallic properties of basalt fiber materials, it is impossible to directly form a complete box structure through welding processes like metal materials, so it is difficult to ensure the connection reliability between the various components of the box, which reduces the overall strength and durability of the box structure. Summary of the invention

[0027] Embodiment 1: The invention provides a dump truck box made of basalt fiber composite material.

[0028] In one embodiment of the present invention, a basalt fiber composite dump truck box includes a bottom plate 1, a front baffle 2, a rear baffle 3 and two side panels 4, the rear baffle 3 is provided with a box door movably mounted at an upper limit, the front baffle 2 and the rear baffle 3 are detachably mounted on opposite sides of the bottom plate 1, slots 5 are respectively provided on the front baffle 2 and the rear baffle 3, the two ends of the two side panels 4 are respectively inserted into the slots 5 and are detachably connected to the front baffle 2 and the rear baffle 3, and the front baffle 2 and the rear baffle 3 are provided with a support plate 6 for supporting the two side panels 4, and the bottoms of the two side panels 4 are detachably connected to the bottom plate 1.

[0029] Specifically, Figures 1 to 3 As shown, in a basalt fiber composite dump truck body of the present invention, since the front baffle 2 and the rear baffle 3 are detachably mounted on the front and rear sides of the base plate 1, respectively, the detachable mounting method of the front baffle 2 and the rear baffle 3 with the base plate 1 can be threaded connection, that is, bolt holes are preset on the base plate 1, the front baffle 2 and the rear baffle 3, and the three are tightly connected with high-strength bolts. The bolt connection has the characteristics of reliable connection and easy disassembly, thereby facilitating the disassembly and assembly of the base plate 1, the front baffle 2 and the rear baffle 3.

[0030] Furthermore, since slots 5 are respectively provided on the front baffle 2 and the rear baffle 3, the front and rear ends of the two side panels 4 are respectively inserted into the slots 5 on the front baffle 2 and the rear baffle 3, so that not only the two side panels 4 can be surrounded by the bottom plate 1, the front baffle 2 and the rear baffle 3 to form a device space for placing materials, but also the two side panels 4 can be prevented from being separated from the front baffle 2 and the rear baffle 3 in the left and right directions, thereby improving the tightness of the connection, and the structural design is simple and reasonable; at the same time, the front and rear ends of the two side panels 4 can be detachably installed with the front baffle 2 and the rear baffle 3 by threaded connection, that is, by pre-setting bolt holes on the two side panels 4 and using high-strength bolts to fasten the two side panels 4 to the front baffle 2 and the rear baffle 3, thereby ensuring the stability and reliability of the connection between the two side panels 4 and 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 a support plate 6 for supporting the two side panels 4, on the one hand, the two side panels 4 can be supported and limited in the up and down directions through the support plate 6, so that when installing the side panels 4, the staff only needs to complete the subsequent fastening operations (such as installing bolts) after inserting them into the slots 5, which not only improves the installation convenience of the two side panels 4 and facilitates assembly, but also reduces the installation difficulty of the side panels 4 and improves the overall assembly efficiency of the vehicle body; on the other hand, the support plate 6 can also provide additional support for the two side panels 4, thereby improving the installation stability of the side panels 4 and the overall structural strength of the vehicle body, thereby improving durability. In addition, after the two side panels 4 are connected to the front baffle 2 and the rear baffle 3, the staff can detachably connect the bottom of the two side panels 4 to the bottom plate 1. The detachable installation method of the two side panels 4 and the bottom plate 1 can adopt a threaded connection. The threaded connection is convenient for disassembly and assembly. Specifically, high-strength bolts can be used to ensure the stability and reliability of the connection between the bottom of the two side panels 4 and the bottom plate 1, thereby further improving the overall structural strength of the vehicle body.

[0031] It is worth mentioning that since the box door is movably installed on the rear baffle 3, the installation method of the box door and the rear baffle 3 can be pin-hinged, and at the same time cooperate with the 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 to complete the unloading operation.

[0032] It should be noted that in a basalt fiber composite dump truck box 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 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., thereby making the comprehensive density of the basalt fiber composite material between 1.85--2.45, which is only between 1 / 4 and 1 / 3 of the steel plate material (density is 7.8). Therefore, the weight of the present invention is greatly reduced because its various panels are made of basalt fiber composite parts, which is more than 1 / 3 lighter than the traditional metal material box, thereby improving the fuel efficiency and load-bearing 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 subjected to heavy loads and complex working conditions. In addition, the basalt fiber composite material also has good corrosion resistance, so the present invention can resist the erosion of various corrosive media such as acids, alkalis, salts, etc. in harsh transportation environments, thereby greatly extending the service life.

[0033] In one 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 extension direction of the side plates 4; first protrusions 9 are formed on opposite sides of the base plates 7, respectively, and the two first protrusions 9 extend along the width direction of the base plates 7, and any two adjacent first protrusions 9 abut against each other and form a clamping portion 10, and a first clamping groove 11 is provided on the connecting plate 8 to be limitedly clamped with the clamping portion 10.

[0034] Specifically, Figures 1 to 4 As shown, since the plurality of substrates 7 in the bottom plate 1 are arranged in sequence along the front-to-back direction, and the first protrusions 9 are formed on the front and rear sides of the plurality of substrates 7, respectively, the first protrusions 9 on the front and rear sides of the two adjacent substrates 7 can abut against each other and thereby form a clamping portion 10 for clamping with the first clamping groove 11, and the structural design is simple and reasonable. Further, when the staff assembles the plurality of substrates 7, since the two first protrusions 9 extend in the left-right direction, by installing the connecting plate 8 between the two adjacent substrates 7, that is, sliding the connecting plate 8 in the left-to-right direction and making the first clamping groove 11 on the connecting plate 8 and the clamping portion 10 limitedly clamped, the two adjacent substrates 7 can be firmly connected, and the above steps can be repeated to realize the overall assembly of the bottom plate 1, which is not only simple to operate, but also simplifies the assembly process of the bottom plate 1, and also improves the convenience of disassembly and assembly between the plurality of substrates 7, which is convenient for replacement and maintenance, and the clamping and matching of the clamping portion 10 and the first clamping groove 11 ensures the connection stability and reliability between the plurality of substrates 7. It can be understood that, compared with the bottom plate 1 of the vehicle box adopting an integral structure in the prior art, the bottom plate 1 of the present invention can be disassembled into several base plates 7, thereby reducing the space occupied by the bottom plate 1 and facilitating transportation and handling.

[0035] In one embodiment, the two connecting plates 8 near the front baffle 2 and the rear baffle 3 are respectively formed with second protrusions 12, and the two second protrusions 12 extend along the width direction of the connecting plate 8. The front baffle 2 and the rear baffle 3 are respectively provided with second slots 13 that are limitedly engaged with the second protrusions 12. Specifically, Figure 1 and Figure 6 As shown, since the second protrusion 12 extends in the left-right direction, the staff can slide the front baffle 2 and the rear baffle 3 in the left-right direction and install them on the two connecting plates 8 at the front and rear ends of the base plate 1 respectively. At this time, the second card groove 13 is engaged with the second protrusion 12, so that a stable connection between the front baffle 2 and the rear baffle 3 and the base plate 1 can be achieved, and the structural design is simple and reasonable.

[0036] In one embodiment, if Figure 4 and Figure 6 As shown, the shape and size of the clamping part 10 and the first clamping slot 11 and the second protrusion 12 and the second clamping slot 13 are consistent and matched with each other. The first clamping slot 11 and the second clamping slot 13 are any one of a T-shaped slot, a dovetail slot or a circular slot, so that a good clamping effect can be formed on the clamping part 10 and the second protrusion 12, ensuring the stability and reliability of the connection between the various plates. It should be noted that the connecting plate 8 can also be made of basalt fiber composite materials, and the first protrusion 9 and the second protrusion 12 can be locally strengthened, so that the bearing capacity of the connecting plate 8, the first protrusion 9 and the second protrusion 12 can be enhanced, and the stable connection between the various plates can be ensured. In addition, the notches at the left and right ends of the first clamping slot 11 and the second clamping slot 13 are both outwardly expanded, so that it is convenient for the staff to smoothly insert the clamping part 10 and the second protrusion 12 into the first clamping slot 11 and the second clamping slot 13, which is convenient for installation.

[0037] In one embodiment, the notch of the slot 5 is arranged to correspond to the notches of the first card slot 11 and the second card slot 13, and plug-in parts 14 are formed at both ends of the two side panels 4. The plug-in parts 14 are plugged into 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 of the two side panels 4; a shielding part 16 for covering the notches of the first card slot 11 and the second card slot 13 is formed at the bottom of the two side panels 4, and locking members are detachably installed on the shielding part 16 at positions corresponding to a plurality of connecting plates 8.

[0038] Specifically, Figures 1 to 4As shown, since the notch of the slot 5 corresponds to the notch of the first card slot 11 and the second card slot 13, when installing the side panel 4, the staff can achieve pre-positioning of the side panel 4 by plugging the plug-in portion 14 of the side panel 4 into the slot 5, effectively preventing the side edge from moving or dislocating in the left and right directions relative to the bottom plate 1; at the same time, the fasteners can be high-strength bolts in the prior art, and the plug-in portion 14 is detachably connected to the front baffle 2 and the rear baffle 3 through a plurality of fasteners, thereby ensuring that the side panel 4 is fixed to the front baffle 2 and the rear baffle 3. The connection between the baffles 3 is stable; and, during the process of installing the fasteners, the side panel 4 is overlapped on the support plate 6 and supported and limited by the support plate 6, thereby effectively preventing the support plate 6 from falling downward and escaping from the slot 5, and by providing a notch groove 15 at the bottom end of the plug-in portion 14 for the support plate 6 to extend into, not only can the contact area between the support plate 6 and the side panel 4 be increased, the abutment tightness between the support plate 6 and the side panel 4 be improved, but also the structural strength between the side panel 4 and the front baffle 2 and the rear baffle 3 is enhanced.

[0039] It can be understood that since a shielding portion 16 is formed at the bottom of the side panel 4, when the side panel 4 is firmly connected to the front baffle 2 and the rear baffle 3 by fasteners, the shielding portion 16 at the bottom of the side panel 4 can cover the two end notches of the first card slot 11 and the second card slot 13 in the left and right directions, thereby effectively preventing the connecting plate 8 from moving relative to the base plate 7 along the left and right directions and separating 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 members on the shielding portion 16 at positions corresponding to several connecting plates 8, the locking members can also be high-strength bolts in the prior art, thereby not only improving the stability of the connection between the side panel 4 and the base plate 1, but also further increasing the connection strength between the panels, and being reliable to use.

[0040] In one embodiment, a top plate 17 is further included, and the top plate 17 is used to cover the inner cavity of the vehicle box. 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 extension direction of the bottom plate 1 through a driving member. Specifically, as Figure 8 As shown, by providing a top plate 17 on the top of the vehicle box, the inner cavity of the vehicle box can be covered, thereby not only protecting the materials and goods in the vehicle box from wind and rain and keeping them dry and clean, but also effectively preventing the goods from completely dumping out of the vehicle box when an accident such as a rollover occurs to the vehicle, thereby effectively reducing the loss of goods, reducing the harm of accidents to personnel and the environment, and improving safety in use. The top plate 17 can support the two side panels 4, thereby improving the ability of the side panels 4 to withstand left and right impact loads and the overall structural strength of the vehicle box, thereby extending the service life of the present invention.

[0041] Furthermore, if Figure 8and Fig.10 As shown, since the left and right sides of the fixing plate 18 in the top plate 17 are detachably connected to the two side plates 4 respectively, the detachable connection method can be a threaded connection, which can not only achieve a stable installation of the fixing plate 18, but also facilitate the disassembly and assembly of the top plate 17 and facilitate maintenance; at the same time, combined with Figure 7 It can be seen that since the two movable plates 19 are installed on the fixed plate 18 in a limited and movable manner along the extension direction (i.e., the front-to-back direction) of the bottom plate 1 by the driving member, the driving member can be a hydraulic cylinder in the prior art, thereby enabling the two movable plates 19 to slide relative to the fixed plate 18 in the front-to-back direction, and the structural design is simple and reasonable. It can be understood that when it is necessary to load goods into the car box, the movable plate 19 at the front end is driven by the driving member to move backward, thereby opening the inner cavity of the car box and realizing the loading of goods; similarly, when the inner space near the front end of the car box is full of goods, the movable plate 19 at the rear end can be driven by the driving member to move forward, and thereby the goods can be loaded into the inner space near the rear end of the car box, thereby ensuring the full utilization of the inner space of the car box and improving the transportation efficiency of the goods. In addition, it should be noted that after the present invention is installed on the vehicle and in 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 car box, thereby ensuring the covering effect of the goods.

[0042] It is worth mentioning that the fixed plate 18 and the two movable plates 19 can both be made of basalt fiber composite materials, thereby ensuring the use effect of the fixed plate 18 and the two movable plates 19, allowing the fixed plate 18 and the two movable plates 19 to withstand a large load without being easily deformed or damaged, thereby improving the supporting stability of the side plate 4, and helping to reduce the overall weight of the vehicle body, improving the fuel economy and driving performance of the vehicle.

[0043] In one embodiment, a limiting step 20 is formed at the bottom of the fixed plate 18, and a plurality of mounting holes are evenly and spaced apart on the limiting step 20 along the extension direction of the bottom plate 1; grooves 21 for slidingly contacting and cooperating with the fixed plate 18 are formed on the bottom surfaces of the two movable plates 19, and limiting grooves 22 are respectively 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 spaced apart on the side walls of the fixed plate 18.

[0044] Specifically, Figure 8 , Fig.10 and Fig.11As shown, since a limiting step 20 is formed at the bottom of the fixing plate 18 in the front-to-back direction, and a plurality of mounting holes are evenly and spaced apart on the side wall of the limiting step 20 in the front-to-back direction, the staff can pass a plurality of high-strength bolts through the plurality of mounting holes one by one and threadedly connect them with the side plate 4 when installing the fixing plate 18, thereby realizing multi-point installation of the fixing plate 18 and ensuring the installation stability of the fixing plate 18 on the side plate 4. Furthermore, by providing grooves 21 on the bottom surfaces of the two movable plates 19, the two movable plates 19 can slide along the extension direction (i.e., the front-to-back direction) of the fixed plate 18 under the action of the driving member, thereby 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 groove walls on both sides of the groove 21 abut against the limiting steps 20, and at this time, the limiting steps 20 can limit the movable plates 19 in the up-down direction, further improving the stability of the movable plates 19 when sliding on and off; and the side walls of the two movable plates 19 can be closely abutted against the two side plates 4, thereby ensuring a stable support effect for the two side plates 4, and the structural design is simple and reasonable. It can be understood that since the limiting grooves 22 are provided on both sides of the two movable plates 19 along the front-to-back direction, and the limiting columns 23 for extending into the limiting grooves 22 are provided on the fixed plate 18, the plug-in cooperation of the limiting columns 23 and the limiting grooves 22 can effectively prevent the movable plates 19 from moving upward and separating from the fixed plate 18, thereby ensuring the sliding stability and installation reliability of the movable plates 19.

[0045] In one embodiment, if Fig. 9 and Fig.10 As shown, inclined plates 24 are detachably mounted on the top surfaces of the two movable plates 19. Specifically, the detachable mounting method of the inclined plates 24 and the movable plates 19 can be threaded, so that the inclined plates 24 can be easily disassembled, assembled, and replaced. Furthermore, by arranging the inclined plates 24 on the movable plates 19, water accumulation on the movable plates 19 can be effectively prevented, thereby improving the shielding and protection effect on the goods. It is worth noting that when installing the inclined plates 24, the staff can install the inclined plates 24 in a forward and backward tilted state, so that the goods can naturally slide into the vehicle box under the action of the inclined plates 24 when loading, which is convenient for loading the goods.

[0046] In one embodiment, a support frame 25 is provided on the bottom surface of the bottom plate 1, and the support frame 25 includes two main longitudinal beams 26 and a plurality of cross beams 27. The two main longitudinal beams 26 are arranged at intervals and extend toward the direction close to the front baffle 2 and the rear baffle 3, and the plurality of cross beams 27 are uniformly and spacedly clamped on the two main longitudinal beams 26 along the extension direction of the bottom plate 1. 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 along the left-right direction and extend in the direction close to the front baffle 2 and the rear baffle 3 (i.e., the front-to-back direction), they can provide the main longitudinal support for the bottom plate 1 and the other panels; at the same time, a number of cross beams 27 are evenly and spacedly connected to the two main longitudinal beams 26 along the front-to-back direction, so as to form a stable grid structure, and thereby provide sufficient lateral support for the bottom plate 1 and the other panels, which can not only effectively prevent the deformation or damage of the car box, but also improve the bearing capacity, and the structural design is simple and reasonable. It should be noted that the bottom plate 1 and the two main longitudinal beams 26 and the number of cross beams 27 can be firmly connected by high-strength threads.

[0047] In one embodiment, the support frame 25 further includes a plurality of secondary longitudinal beams 28, which are arranged at positions corresponding to the two side panels 4; hinge plates 29 are respectively arranged at positions near the rear baffle 3 on both sides of the two main longitudinal beams 26; and a hinge seat 30 is arranged on the front baffle 2. Specifically, Figure 1 , Figure 5 and Figure 7 As shown, by arranging a plurality of secondary longitudinal beams 28 at positions corresponding to the two side panels 4, additional support can be provided for the two side panels 4, and a frame structure can be formed between the secondary longitudinal beams 28 and the main longitudinal beams 26 and the cross beams 27, thereby enhancing the structural strength of the support frame 25, so that the present invention can withstand greater weight and pressure. By articulating the hinge plate 29 to the vehicle and the articulated seat 30 to the external lifting mechanism, the present invention can be easily turned over for easy unloading.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
