Description

Technical Field

[0001] This application belongs to the technical field of mining vehicles, specifically relating to an articulated hood for a mining truck and a mining truck. Background Technology

[0002] Mining trucks, also known as mining dump trucks, are used to transport ore, waste soil, or earthwork in open-pit mines. They are typically powered by diesel or electricity. For mining trucks powered by diesel, the engine is located at the front of the vehicle body, and the vehicle body is equipped with a cover to protect the engine and ensure its stable operation.

[0003] To facilitate engine maintenance, existing engine hoods are typically hinged to the vehicle body, with the hinge located at the front. This allows the hood to have two positions: an open position where it flips forward to expose the engine, and a closed position where the hood covers the engine and its hinge-off end rests against the vehicle body. Due to the large size of the engine, the engine hood is also large. This means that when the hood is rotated to the closed position, the end away from the hinge axis may tilt. Consequently, after the hood is closed, this side may move outside the vehicle body, resulting in a lack of support on that side. Over time, this could cause the hood to sag, ultimately affecting the quality of the mining truck.

[0004] To prevent the hood from tilting when moving towards the closed position, a guide seat is typically installed inside the hood at the end furthest from its hinge axis. This guide seat has a guide groove, and a guide block is mounted on the vehicle body. When the hood is moving towards the closed position, the guide block extends into the guide groove, allowing the hood to adjust itself under the influence of the groove wall and the guide block, ensuring accurate movement to the closed position. To reduce the size of the hood, the guide seat and guide block are also small. This means they only come into contact and provide guidance when the hood is about to reach the closed position. However, in some cases, the hood may have already tilted before reaching the closed position, preventing the guide block from extending into the guide groove. This results in the guide block failing to engage with the guide groove to correct the hood's deviation, leading to poor guiding performance. Utility Model Content

[0005] This application provides an articulated hood for mining trucks to improve the guiding effect of the hood.

[0006] The technical solution adopted in this application is as follows:

[0007] A hinged engine cover for a mining truck includes an engine cover body and guide seats. The engine cover body has a hinged end that is hinged to the front of the vehicle body and an opening and closing end opposite to the hinged end. At least two guide seats are provided and are respectively located on both sides in the forward direction of the vehicle body. Each guide seat extends vertically and can contact and cooperate with the inner wall of the engine cover body. The distance from the guide seat to the hinged end is less than the distance from the guide seat to the opening and closing end.

[0008] By adopting the above technical solution, since the distance from the guide seat to the hinge end is less than the distance from the guide seat to the opening / closing end, the guide seat is closer to the hinge end than the opening / closing end. Furthermore, because the guide seat extends vertically, it can contact the inner wall of the hood body as it moves from the open position to the closed position to guide and adjust the hood body. This increases the guiding stroke of the guide seat on the hood body, preventing the hood body from tilting to the closed position. This ensures the hood body moves accurately to the closed position, guaranteeing that both sides of the hood are supported by the vehicle body, preventing sagging due to lack of support on one side. This, in turn, ensures the product quality of the mining truck and improves the user experience.

[0009] In summary, compared with the prior art, the technical solution of this application greatly increases the guiding stroke of the hood body, so as to avoid the hood body from deflecting during the movement toward the closed position, thereby improving the guiding effect of the hood body.

[0010] Optionally, a reinforcing beam is provided inside the machine cover body. The reinforcing beam extends from the hinge end along the inner contour of the machine cover body to the opening end. The reinforcing beam has a first section located near the hinge axis of the machine cover body, a second section located away from the hinge axis of the machine cover body, and an intermediate section located between the first section and the second section. The guide seat is provided corresponding to the intermediate section, and the length of the first section is less than the length of the second section.

[0011] By adopting the above technical solution, when the hood body is closed, the guide seat and the middle section make contact and cooperate, so as to guide the hood body by means of the guide seat and the middle section, so as to prevent the hood body from deviating during the movement towards the closed position.

[0012] Since the middle section is located between the first and second sections, the guide seat is set corresponding to the middle section, and the length of the first section is less than the length of the second section. This keeps the distance between the guide seat and the hinge end within a reasonable range. On the one hand, it can reduce the size design of the guide seat to avoid interference between the guide seat and the inner top wall of the machine cover body. On the other hand, it can also reduce the production cost of the guide seat to reduce the production cost of the hinged machine cover. Furthermore, it can also guide the machine cover body when the machine cover body begins to move towards the closed position, thereby increasing the guiding effect on the machine cover body.

[0013] Furthermore, by setting up reinforcing beams, the machine cover body is strengthened on the one hand to increase its structural strength, and on the other hand, friction between the guide seat and the machine cover body can be avoided to prevent wear on the machine cover body, thus ensuring the service life of the machine cover body.

[0014] Optionally, a mating plate is fixedly connected to the intermediate section corresponding to the guide seat, and one bottom end of the mating plate is attached to the outer contour of the intermediate section.

[0015] By adopting the above technical solution, since the guide seat of the middle section is fixedly connected to the mating plate, the guide seat contacts the middle section through the mating plate. On the one hand, this increases the contact area between the guide seat and the middle section, thereby improving the guiding effect on the machine cover body. On the other hand, it also avoids friction between the guide seat and the middle section, thus ensuring the structural strength of the reinforcing beam. Furthermore, since one end of the mating plate is attached to the outer contour of the middle section, it further avoids the situation where the mating plate and the guide seat get stuck when the machine cover body is slightly tilted, thereby reducing the difficulty of closing the machine cover body and ensuring the smoothness of the machine cover body moving towards the closed position.

[0016] Optionally, the guide seat has a connecting end connected to the vehicle body, a guide end opposite to the connecting end, and a guide surface that can contact the mating plate, wherein the guide surface is inclined at the guide end toward the direction away from the mating plate.

[0017] By adopting the above technical solution, since the guide surface extends in the direction away from the mating plate at the guide end, the difficulty of contact and mating between the guide seat and the mating plate can be reduced, so as to avoid the situation where the guide seat and the mating plate get stuck together due to a slight deviation of the machine cover body. This reduces the difficulty of driving the machine cover body from the open position to the closed position, and at the same time ensures the smoothness of the movement of the machine cover body from the open position to the closed position.

[0018] Optionally, the interior of the hood body has a crossbeam, which extends along the internal contour of the hood body, and both ends of the crossbeam are fixedly connected to the middle section, and the mating plate is fixedly connected to the crossbeam.

[0019] By adopting the above technical solution, the structural strength of the machine cover body is further increased due to the presence of a crossbeam inside. Furthermore, since the two ends of the crossbeam are fixedly connected to the middle section, the crossbeam and the reinforcing beam are integrated into one unit, further increasing the structural strength of the machine cover body. Additionally, the mating plate is fixedly connected to the crossbeam, thereby increasing the connection strength between the crossbeam and the reinforcing beam and enhancing the connection stability between them.

[0020] Optionally, the engine hood body is provided with a longitudinal beam inside, the longitudinal beam extending from the hinge end along the inner contour of the engine hood body towards the opening end, and the longitudinal beam and the crossbeam are arranged to intersect at the top of the engine.

[0021] By adopting the above technical solution, the structural strength of the engine hood body can be further increased due to the longitudinal beams installed inside the engine hood body. Furthermore, since the longitudinal beams and crossbeams are intersected at the top of the engine, the longitudinal beams and crossbeams are integrated, thereby further increasing the reinforcing effect of the crossbeams and longitudinal beams on the engine hood body.

[0022] Optionally, a reinforcing plate is provided at the intersection of the longitudinal beam and the transverse beam. One side of the reinforcing plate is fixedly connected to the longitudinal beam, and the other side of the reinforcing plate is fixedly connected to the transverse beam. The reinforcing plate is provided with a lifting screw seat for threaded connection of the lifting eye bolt. The machine cover body is provided with a through hole corresponding to the lifting screw seat for the threaded rod of the lifting eye bolt to pass through.

[0023] By adopting the above technical solution, a reinforcing plate is provided at the intersection of the longitudinal beam and the transverse beam, with one side of the reinforcing plate fixedly connected to the longitudinal beam and the other side fixedly connected to the transverse beam, thereby increasing the connection strength between the longitudinal beam and the transverse beam, and further enhancing the reinforcing effect of the longitudinal beam and the transverse beam on the machine cover body. Furthermore, since the reinforcing plate is equipped with a lifting screw seat for threaded connection of the lifting eye bolt, and the machine cover body is equipped with a corresponding threaded rod for the lifting eye bolt, the lifting eye bolt and lifting equipment can be used to assist in the installation of the articulated machine cover. In other words, when installing the articulated machine cover, the threaded rod of the lifting eye bolt can be passed through the through hole and threaded into the lifting screw seat, and then the lifting equipment can be connected to the lifting bolt to lift the articulated machine cover, thus reducing the difficulty of installing the articulated machine cover.

[0024] Optionally, both the longitudinal beam and the transverse beam are provided with connecting screw seats so that the fire extinguishing device can be fixed to the inside of the machine cover body using bolts.

[0025] By adopting the above technical solution, since both the longitudinal beams and the transverse beams are equipped with connecting screw seats, the fire extinguishing device can be fixed inside the machine hood body using bolts, thus avoiding the need to use cable ties or wires to fix the fire extinguishing device. This reduces the difficulty of fixing the fire extinguishing device and increases the connection stability between the fire extinguishing device and the machine hood body.

[0026] Optionally, the hinged hood also includes a hood lock, wherein the bolt of the hood lock is located inside the hood body and at the opening end, the lock body of the hood lock is located on the vehicle body, and the hood body is provided with an access port opposite to the hood lock and a cover plate detachably connected to the access port.

[0027] And / or, the interior of the machine cover body is provided with heat insulation cotton.

[0028] By adopting the above technical solution, since the bolt of the hood lock is located inside the hood body and at the engaging end, and the lock body is located on the vehicle body, the hood body can be locked by the cooperation of the lock body and the bolt, thereby increasing the stability of the hood body when it is in the closed position. Furthermore, since the access port is located opposite the hood lock and the cover plate is detachably connected to the access port, when the hood lock malfunctions, the cover plate can be removed, and then the operator can insert tools through the access port into the interior of the hood body to release the locking cooperation between the lock body and the bolt, thus unlocking the hood body. This reduces the difficulty of repairing the hood lock when it malfunctions.

[0029] Because the engine cover is equipped with heat insulation cotton inside, the temperature of the engine cover surface is reduced, so as to avoid the possibility of the engine cover causing injury to the staff, and to facilitate the staff to operate the engine cover for engine maintenance.

[0030] This application also discloses a mining truck to avoid the situation where deformation of the engine cover affects the quality of the mining truck.

[0031] A mining truck includes a body, an engine located at the front of the body, and an articulated hood as described above, wherein the articulated end of the hood body is hinged to the front of the body, and the hood body is capable of covering the outside of the engine.

[0032] By adopting the above technical solution, since the mining truck in this application uses the aforementioned articulated hood, the situation where the hood body moves and tilts during the closing process is avoided, thereby preventing the hood body from sagging due to lack of support on one side, and thus ensuring the product quality of the mining truck.

[0033] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0034] 1. The articulated hood in this application includes a hood body and guide seats. The hood body has a hinged end hinged to the front of the vehicle body and an opening / closing end opposite to the hinged end. At least two guide seats are provided and are located on both sides in the forward direction of the vehicle body. Each guide seat extends vertically and can contact and cooperate with the inner wall of the hood body. The distance from the guide seat to the hinged end is less than the distance from the guide seat to the opening / closing end. This allows the hood body to move from the open position to the closed position until it contacts the inner wall of the hood body for guidance. This increases the guiding stroke of the guide seats on the hood body, preventing the hood body from tilting to the closed position. This ensures that the hood body can accurately move to the closed position, ensuring that the vehicle body can support both sides of the hood, preventing the hood body from sagging due to lack of support on one side. This, in turn, ensures the product quality of the mining truck and improves the user experience.

[0035] 2. The housing body of this application has a reinforcing beam inside. The reinforcing beam extends from the hinge end along the internal contour of the housing body to the opening end. The reinforcing beam has a first section located near the hinge axis of the housing body, a second section located away from the hinge axis of the housing body, and an intermediate section located between the first and second sections. The guide seat is provided corresponding to the intermediate section, and the length of the first section is less than the length of the second section. This keeps the distance between the guide seat and the hinge end within a reasonable range. On the one hand, it can reduce the size design of the guide seat to avoid interference between the guide seat and the internal top wall of the housing body. On the other hand, it can also reduce the production cost of the guide seat, thereby reducing the production cost of the hinged housing. Furthermore, it can also guide the housing body when it begins to move toward the closed position, thereby increasing the guiding effect on the housing body.

[0036] 3. In this application, the intermediate section is fixedly connected to the guide seat with a mating plate, so that the guide seat contacts the intermediate section through the mating plate. On the one hand, this increases the contact area between the guide seat and the intermediate section to improve the guiding effect on the machine cover body. On the other hand, it can also avoid the friction between the guide seat and the intermediate section to ensure the structural strength of the reinforcing beam. The bottom end of the mating plate is attached to the outer contour of the intermediate section, which can further prevent the mating plate from getting stuck with the guide seat when the machine cover body is slightly tilted. This reduces the difficulty of closing the machine cover body and ensures the smoothness of the machine cover body when it moves toward the closed position. Attached Figure Description

[0044] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0047] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0049] Reference Figures 1 to 4 A hinged engine cover for a mining truck is disclosed, comprising an engine cover body 1 and guide seats 2. The engine cover body 1 has a hinge end hinged to the front of the vehicle body and an opening and closing end opposite to the hinge end. At least two guide seats 2 are provided and are respectively located on both sides in the forward direction of the vehicle body. Each guide seat 2 extends vertically and can contact and cooperate with the inner wall of the engine cover body 1. The distance from the guide seat 2 to the hinge end is less than the distance from the guide seat 2 to the opening and closing end.

[0050] Because the distance from the guide seat 2 to the hinge end is less than the distance from the guide seat 2 to the opening / closing end, the guide seat 2 is closer to the hinge end than the opening / closing end. Since the guide seat 2 extends vertically, it can contact the inner wall of the hood body 1 when the hood body 1 moves from the open position to the closed position, thus guiding the hood body 1. This increases the guiding stroke of the guide seat 2 on the hood body 1, preventing the hood body 1 from tilting to the closed position. This ensures the hood body 1 can accurately move to the closed position, guaranteeing that both sides of the hood body 1 are supported by the vehicle body, preventing sagging due to lack of support on one side. This, in turn, ensures the product quality of the mining truck and improves the user experience.

[0051] In summary, compared with the prior art, the technical solution of this application greatly increases the guiding stroke of the hood body 1, so as to avoid the hood body 1 from deflecting during the movement toward the closed position, thereby improving the guiding effect of the hood body 1.

[0052] It should be noted that by increasing the height of the guide seat 2, the guide seat 2 can always contact the inner wall of the cover body 1 when the cover body 1 moves between the open and closed positions, so that the guide seat 2 can continuously guide the cover body 1. Since the cover body 1 has a certain height, as long as the height of the guide seat 2 does not exceed the height of the cover body 1, the situation of increasing the volume of the cover body 1 due to the setting of the guide seat 2 can be avoided.

[0053] Preferably, there are two guide seats 2, which are located on both sides of the vehicle body in the direction of travel. That is, one guide seat 2 is located on the left side of the vehicle body and the other guide seat 2 is located on the right side of the vehicle body.

[0054] This application does not specify the hinge method between the hood body 1 and the vehicle body; preferably, refer to... Figure 3 The front end of the engine cover body 1 is fixedly connected to a hinge moving piece 11, the side of the hinge moving piece 11 is fixedly connected to a hinge shaft 111, the vehicle body is fixedly connected to a hinge stationary piece 3, the hinge stationary piece 3 is provided with a hinge shaft hole, and the hinge shaft 111 passes through the hinge shaft hole to realize the hinge connection between the engine cover body 1 and the vehicle body.

[0055] By using a hinge shaft 111 located on the side of the hinge moving piece 11 and a hinge shaft hole located on the hinge stationary piece 3 to achieve the hinge connection between the engine cover body 1 and the vehicle body, the hinge stationary piece 3 and the hinge moving piece 11 can be thickened, and the hinge shaft 111 can also be thickened to increase the hinge stability between the engine cover body 1 and the vehicle body.

[0056] Preferably, the hinge stationary plate 3 is provided with an oil injection nozzle, which is connected to the hinge shaft hole so that grease can be added to the hinge shaft hole through the oil injection nozzle. The grease is used to lubricate the hinge shaft 111, thereby reducing the friction between the hinge shaft 111 and the wall of the hinge shaft hole, and thus reducing the wear of the hinge shaft 111 and the hinge shaft hole.

[0057] Preferably, there are two hinge moving pieces 11 spaced apart, and two hinge stationary pieces 3 corresponding to the hinge moving pieces 11, so as to increase the number of hinge points between the engine cover body 1 and the vehicle body, thereby increasing the hinge stability between the engine cover body 1 and the vehicle body.

[0058] In other embodiments, the hood body 1 can also be hinged to the vehicle body using a hinge connection.

[0059] In a preferred embodiment, refer to Figure 2 The articulated hood also includes a hydraulic cylinder 4. The cylinder body of the hydraulic cylinder 4 is hinged to the vehicle body, and the piston rod of the hydraulic cylinder 4 is hinged to the inside of the front end of the hood body 1. The hinge position between the cylinder body and the vehicle body is spaced apart from the hinge axis between the hood body 1 and the vehicle body. The connection position between the piston rod and the hood body 1 is also spaced apart from the hinge axis between the hood body 1 and the vehicle body. This allows the hood body 1 to move between the closed and open positions by extending and retracting the piston rod of the hydraulic cylinder 4. Furthermore, using the hydraulic cylinder 4 to drive the hood body 1 reduces the production cost of the articulated hood compared to using an electric cylinder.

[0060] Of course, in other embodiments, a cylinder or other structure capable of driving the hood body 1 to rotate can also be used to drive the hood body 1.

[0061] This application does not specify the connection method between the guide seat 2 and the vehicle body. Preferably, the guide seat 2 is fixedly connected to the vehicle body by bolts to reduce the installation difficulty of the guide seat 2 and increase its stability. In other embodiments, the guide seat 2 can also be welded to the vehicle body.

[0062] In a preferred embodiment, refer to Figure 2 and Figure 3 The machine cover body 1 is provided with a reinforcing beam 12 inside. The reinforcing beam 12 extends from the hinge end along the inner contour of the machine cover body 1 to the opening end. The reinforcing beam 12 has a first section 121 that is close to the hinge axis of the machine cover body 1, a second section 122 that is far away from the hinge axis of the machine cover body 1, and an intermediate section 123 located between the first section 121 and the second section 122. The guide seat 2 is provided corresponding to the intermediate section 123, and the length of the first section 121 is less than the length of the second section 122.

[0063] It should be noted that there are two sets of reinforcing beams 12, which are located on both sides of the hinge end, and both sets of reinforcing beams 12 are located at the lower edge of the machine cover body 1. The width of the machine cover body 1 gradually increases from the hinge end to the opening end, which causes the angles formed by the first section 121, the middle section 123, and the second section 122 with the hinge axis of the machine cover body 1 to gradually increase. That is to say, the angle formed by the middle section 123 with the hinge axis of the machine cover body 1 is greater than the angle formed by the first section 121 with the hinge axis of the machine cover body 1, and the angle formed by the second section 122 with the hinge axis of the machine cover body 1 is greater than the angle formed by the middle section 123 with the hinge axis of the machine cover body 1.

[0064] When the hood body 1 is closed, the guide seat 2 and the middle section 123 are in contact and engaged, so as to guide the hood body 1 by means of the guiding engagement between the guide seat 2 and the middle section 123, so as to prevent the hood body 1 from deviating during the movement toward the closed position.

[0065] Since the middle section 123 is located between the first section 121 and the second section 122, the guide seat 2 is set corresponding to the middle section 123, and the length of the first section 121 is less than the length of the second section 122. This keeps the distance between the guide seat 2 and the hinge end within a reasonable range. On the one hand, it can reduce the size design of the guide seat 2 to avoid interference between the guide seat 2 and the inner top wall of the machine cover body 1. On the other hand, it can also reduce the production cost of the guide seat 2 to reduce the production cost of the hinged machine cover. Furthermore, it can also guide the machine cover body 1 when the machine cover body 1 begins to move toward the closed position, thereby increasing the guiding effect on the machine cover body 1.

[0066] Furthermore, by setting the reinforcing beam 12, on the one hand, the machine cover body 1 is strengthened to increase the structural strength of the machine cover body 1, and on the other hand, the friction between the guide seat 2 and the machine cover body 1 is avoided to prevent wear of the machine cover body 1, so as to ensure the service life of the machine cover body 1.

[0067] Preferably, the reinforcing beam 12 is a tubular structure, so as to reduce the weight increase of the hinged hood while ensuring the reinforcement effect on the hood body 1, thereby reducing the load on the hydraulic cylinder 4.

[0068] This application does not specify the connection method between the reinforcing beam 12 and the hood body 1. Preferably, refer to... Figure 2 and Figure 3 The reinforcing beam 12 is fixedly connected to the machine cover body 1 by bolts. For example, a fixing plate is provided on the side of the reinforcing beam 12, and the bolt passes through the fixing plate and is threaded to the machine cover body 1, so as to reduce the production difficulty of the hinged machine cover and improve the production efficiency of the hinged machine cover. In other embodiments, the reinforcing beam 12 can also be fixedly connected to the machine cover body 1 by welding.

[0069] Furthermore, refer to Figure 2 and Figure 3 The middle section 123 is fixedly connected to the guide seat 2 with a mating plate 124, and one bottom end of the mating plate 124 is attached to the outer contour of the middle section 123.

[0070] It is understandable that the bottom end of the mating plate 124 is bent in a direction away from the guide seat 2 so that the bottom end of the mating plate 124 fits the outer contour of the middle section 123.

[0071] Since the intermediate section 123 is fixedly connected to the guide seat 2 with a mating plate 124, the guide seat 2 contacts the intermediate section 123 through the mating plate 124. On the one hand, this increases the contact area between the guide seat 2 and the intermediate section 123, thereby improving the guiding effect on the machine cover body 1. On the other hand, it also avoids friction between the guide seat 2 and the intermediate section 123, thus ensuring the structural strength of the reinforcing beam 12. Furthermore, since one bottom end of the mating plate 124 is attached to the outer contour of the intermediate section 123, it further avoids the situation where the mating plate 124 and the guide seat 2 get stuck when the machine cover body 1 is slightly tilted. This reduces the difficulty of closing the machine cover body 1 and ensures the smoothness of the movement of the machine cover body 1 toward the closed position.

[0072] Furthermore, refer to Figure 2 , Figure 3 and Figure 4 The guide seat 2 has a connecting end connected to the vehicle body, a guide end opposite to the connecting end, and a guide surface 21 that can contact the mating plate 124. The guide surface 21 is inclined in the direction away from the mating plate 124 at the guide end, which can reduce the difficulty of contact and mating between the guide seat 2 and the mating plate 124, so as to avoid the situation where the guide seat 2 and the mating plate 124 get stuck together due to a slight deviation of the hood body 1. This reduces the difficulty of driving the hood body 1 from the open position to the closed position, and also ensures the smoothness of the movement of the hood body 1 from the open position to the closed position.

[0073] Furthermore, refer to Figure 2 and Figure 3 The machine cover body 1 has a crossbeam 13 inside. The crossbeam 13 extends along the internal contour of the machine cover body 1, and the two ends of the crossbeam 13 are fixedly connected to the middle section 123 respectively. The mating plate 124 is fixedly connected to the crossbeam 13.

[0074] Since the machine cover body 1 has a crossbeam 13 inside, the structural strength of the machine cover body 1 is further increased. Since the two ends of the crossbeam 13 are fixedly connected to the middle section 123 respectively, the crossbeam 13 and the reinforcing beam 12 are connected as one, thereby further increasing the structural strength of the machine cover body 1. Furthermore, the mating plate 124 is fixedly connected to the crossbeam 13, thereby increasing the connection strength between the crossbeam 13 and the reinforcing beam 12, thereby increasing the connection stability between the crossbeam 13 and the reinforcing beam 12.

[0075] Preferably, two sets of crossbeams 13 are arranged at intervals along the length of the vehicle body. One set of crossbeams 13 is fixedly connected to the middle section 123 at both ends, and the other set of crossbeams 13 is fixedly connected to the second section 122 at both ends, so as to further increase the structural strength of the engine cover body 1.

[0076] This application does not specifically limit the structure of the crossbeam 13. Preferably, the crossbeam 13 is a tubular structure, so as to ensure the reinforcement effect on the hood body 1 while reducing the increase in weight of the hood body 1 caused by the setting of the crossbeam 13.

[0077] This application does not specify the connection method between the crossbeam 13 and the machine cover body 1. Preferably, the crossbeam 13 is fixedly connected to the machine cover body 1 by bolts, so as to reduce the assembly difficulty of the crossbeam 13 and thus improve the production efficiency of the hinged machine cover. In other embodiments, the crossbeam 13 can also be fixedly connected to the machine cover by welding.

[0078] Furthermore, refer to Figure 2 and Figure 3 The engine cover body 1 is provided with a longitudinal beam 14 inside. The longitudinal beam 14 extends from the hinge end along the inner contour of the engine cover body 1 to the opening end, and the longitudinal beam 14 and the cross beam 13 are arranged to cross each other on the top of the engine.

[0079] Since the engine cover body 1 has longitudinal beams 14 inside, the structural strength of the engine cover body 1 can be further increased. Since the longitudinal beams 14 and the crossbeams 13 are arranged to cross each other on the top of the engine, the longitudinal beams 14 and the crossbeams 13 are connected as one unit, thereby further increasing the strengthening effect of the crossbeams 13 and the longitudinal beams 14 on the engine cover body 1.

[0080] This application does not specifically limit the structure of the longitudinal beam 14. Preferably, the longitudinal beam 14 is a tubular structure, so as to reduce the increase in weight of the machine cover body 1 caused by setting the longitudinal beam 14 while ensuring the reinforcement effect on the machine cover body 1.

[0081] Preferably, two sets of longitudinal beams 14 are arranged at intervals along the width direction of the vehicle body. One set of longitudinal beams 14 is arranged near the hinge end, and the other set of longitudinal beams 14 is arranged near the opening and closing end, so as to further increase the structural strength of the hood body 1. A connecting beam is arranged between the two sets of longitudinal beams 14. The two ends of the connecting beam are fixedly connected to the ends of the two sets of longitudinal beams 14 respectively. The connecting beam is located at the hinge end, so as to connect the two sets of longitudinal beams 14 into a whole. The hinge moving piece 11 is fixedly connected to the longitudinal beam 14, so as to further increase the connection stability between the hood body 1 and the vehicle body.

[0082] This application does not specify the connection method between the longitudinal beam 14 and the machine cover body 1. Preferably, the longitudinal beam 14 is fixedly connected to the machine cover body 1 by bolts to facilitate the installation of the longitudinal beam 14. In other embodiments, the longitudinal beam 14 can also be fixedly connected to the machine cover body 1 by welding.

[0083] Preferably, the longitudinal beam 14 is an integral structure extending from the hinge end to the opening end, while the crossbeam 13 is a multi-segment structure divided by the longitudinal beam 14. Each crossbeam 13 is fixedly connected to the longitudinal beam 14 by welding to ensure the structural strength of the longitudinal beam 14, thereby ensuring the reinforcing effect of the longitudinal beam 14 on the machine cover body 1.

[0084] Furthermore, refer to Figure 2 and Figure 3 A reinforcing plate 141 is provided at the intersection of the longitudinal beam 14 and the transverse beam 13. One side of the reinforcing plate 141 is fixedly connected to the longitudinal beam 14, and the other side of the reinforcing plate 141 is fixedly connected to the transverse beam 13. The reinforcing plate 141 is provided with a lifting screw seat 142 for threaded connection of the lifting eye bolt. The machine cover body 1 is provided with a through hole corresponding to the lifting screw seat 142 for the threaded rod of the lifting eye bolt to pass through.

[0085] It is understandable that the longitudinal beams 14 and the cross beams 13 are arranged in two sets at intervals, so that the longitudinal beams 14 and the cross beams 13 have four intersection points above the engine. That is to say, at least four reinforcing plates 141 are provided, and each reinforcing plate 141 is provided with a lifting screw seat 142. The engine cover body 1 is provided with a through hole corresponding to each lifting screw seat 142, so as to increase the number of lifting points for the engine cover body 1.

[0086] Because a reinforcing plate 141 is provided at the intersection of the longitudinal beam 14 and the transverse beam 13, and one side of the reinforcing plate 141 is fixedly connected to the longitudinal beam 14 and the other side of the reinforcing plate 141 is fixedly connected to the transverse beam 13, the connection strength between the longitudinal beam 14 and the transverse beam 13 is increased, thereby further increasing the reinforcing effect of the longitudinal beam 14 and the transverse beam 13 on the machine cover body 1; and because the reinforcing plate 141 is provided with a lifting screw seat 142 for threaded connection of the lifting eye bolt, and the machine cover body 1 is provided with a screw rod for the lifting eye bolt corresponding to the lifting screw seat 142, when installing the hinged machine cover, the lifting eye bolt and lifting equipment can be used to assist in the lifting. That is to say, when installing the hinged machine cover, the screw rod of the lifting eye bolt can be passed through the through hole and threaded into the lifting screw seat 142, and then the lifting equipment can be connected to the lifting bolt, so as to use the lifting equipment and the lifting eye bolt to lift the hinged machine cover, thereby reducing the difficulty of installing the hinged machine cover.

[0087] Furthermore, refer to Figure 2 and Figure 3 Both the longitudinal beam 14 and the transverse beam 13 are equipped with connecting screw seats 143, so that the fire extinguishing device can be fixed to the inside of the machine cover body 1 with bolts, so as to avoid the need to use cable ties or wires to fix the fire extinguishing device. On the one hand, it reduces the difficulty of fixing the fire extinguishing device, and on the other hand, it increases the connection stability between the fire extinguishing device and the machine cover body 1.

[0088] It should be noted that the fire extinguishing device mentioned in this application, which uses bolts to fix the fire extinguishing device to the inside of the machine cover body 1, can be a fire extinguisher. That is, the clamp for fixing the fire extinguisher is connected to the connecting thread seat 143 by bolt threads to fix the fire extinguisher to the machine cover body 1. The fire extinguishing device can also be a conveying pipeline for conveying fire extinguishing materials. That is, the clamp for fixing the conveying pipeline is connected to the connecting thread seat 143 by bolt threads to fix the conveying pipeline to the machine cover body 1.

[0089] In a preferred embodiment, refer to Figure 2 and Figure 3 The hinged hood also includes a hood lock 5. The bolt of the hood lock 5 is located inside the hood body 1 and at the opening end. The lock body of the hood lock 5 is located on the vehicle body. The hood body 1 is provided with an inspection port opposite to the hood lock 5 and a cover plate 15 that is detachably connected to the inspection port.

[0090] Specifically, a mounting plate is provided between the crossbeam 13 and the longitudinal beam 14 located near the opening and closing end. The locking bolt of the cover lock 5 is fixedly connected to the mounting plate by bolt pairs to increase the locking effect of the cover lock 5 on the cover body 1.

[0091] Because the bolt of the hood lock 5 is located inside the hood body 1 and at the engaging end, and the lock body of the hood lock 5 is located on the vehicle body, the hood body 1 can be locked by the cooperation of the lock body and the bolt, thereby increasing the stability of the hood body 1 when it is in the closed position. Furthermore, because the access port is opposite to the hood lock 5 and the cover plate 15 is detachably connected to the access port, when the hood lock 5 malfunctions, the cover plate 15 can be removed, and then the operator can insert tools through the access port into the interior of the hood body 1 to release the locking cooperation between the lock body and the bolt, thus unlocking the hood body 1. This reduces the difficulty of repairing the hood lock 5 when it malfunctions.

[0092] This application does not specify a particular method for the detachable connection between the cover plate 15 and the inspection port. Preferably, the cover plate 15 is provided with multiple fixing bolts along its circumference, and the fixing bolts are threadedly connected to the machine cover body 1 to achieve a detachable connection between the cover plate 15 and the machine cover body 1. In other embodiments, the detachable connection between the cover plate 15 and the machine cover body 1 can also be achieved by magnetic attraction or snap-fit.

[0093] In a preferred embodiment, the interior of the engine hood body 1 is provided with heat insulation cotton. The heat insulation cotton is either pasted to the inner wall of the engine hood body 1 or fixed to the inner wall of the engine hood body 1 by fasteners, so that the heat insulation cotton isolates the heat generated by the engine, thereby reducing the transfer of heat from the engine to the engine hood body 1, thereby reducing the temperature of the engine hood body 1 and avoiding the possibility of injury to the staff due to the high temperature of the engine hood body 1.

[0094] In a preferred embodiment, refer to Figure 1 The hinged end is provided with a maintenance port, and a center grille 6 is provided at the maintenance port. One side of the center grille 6 is hinged to the engine hood body 1, so that the maintenance port can be opened or closed by rotating the center grille 6 to facilitate the inspection and maintenance of the components on the front side of the engine. The other side of the center grille 6 is provided with a flat lock. The locking tongue of the flat lock can cooperate with the inner wall stop of the engine hood body 1 to lock the center grille 6.

[0095] This application also discloses a mining truck, which includes a vehicle body, an engine located at the front of the vehicle body, and an articulated engine cover as described above. The articulated end of the engine cover body 1 is hinged to the front of the vehicle body, and the engine cover body 1 can cover the outside of the engine.

[0096] Because the mining truck in this application adopts the aforementioned articulated hood, the situation where the hood body 1 moves and tilts during the closing process is avoided, thereby preventing the hood body 1 from sagging due to lack of support on one side, and thus ensuring the product quality of the mining truck.
