[0023] To better understand the purpose, structure, and function of this utility model, a dump truck of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] like Figure 1-7As shown, this utility model dump truck includes a dump truck 1, a main beam 2, wheel frames 3, wheels 4, and a tow bar 5. The dump truck 1 is mounted on the main beam 2. The wheels 4 are mounted on both sides of the dump truck 1 in a left-right correspondence via the main beam 2. A pair of corresponding wheel frames 3 are provided at both ends of the main beam 2, and they are rotatably connected to each other. The wheels 4 correspond to the wheel frames 3 and are located on the outside of the wheel frames 3. The wheels 4 are mounted on the main beam 2 via the wheel frames 3. The tow bar 5 is located on the front side of the main beam 2 below the dump truck 1, and its tail end is rotatably connected to the front side wall of the main beam 2. The front of the tow bar 5... The tipper truck extends forward towards the front of the truck bed 1. The tipper truck is connected to the corresponding power vehicle via the front end of the tow bar 5. The tow bar 5 is equipped with a safety lock 6 corresponding to the truck bed 1. The lower side of the truck bed 1 is equipped with a safety buckle 61 corresponding to the safety lock 6. The connection and disconnection between the front end of the truck bed 1 and the tow bar 5 can be controlled by the cooperation of the safety buckle 61 and the safety lock 6. The upper part of the truck bed 1 is equipped with a handrail 7. In this embodiment, the handrail 7 is located at the upper front end of the truck bed 1, which makes it more convenient for workers to tow the tipper truck. All components of the tipper truck are mirror images of each other along its axis, resulting in better stability.

[0025] The wheel frame 3 is U-shaped with its opening facing downwards. Two corresponding wheel frames 3 are respectively located on both sides of the truck bed 1. Each wheel frame includes a top crossbar 31 and a pair of vertical bars 32 parallel to each other at both ends of the crossbar 31. Below the crossbar 31 is a support block 33 corresponding to the main beam 2. The top of the support block 33 is fixedly connected to the middle of the crossbar 31. A bushing 34 is located at the lower part of the support block 33. A rotating shaft 22 corresponding to the bushing 34 is located at the end of the main beam 2. The rotating shaft 22 corresponds to the bushing 34 at its corresponding end. The wheel frame 3 and the main beam 2 are rotatably connected through the cooperation of the bushing 34 and the rotating shaft 22. Wheels 4 are arranged in pairs along the centerline on the outer side of the wheel frame 3. In this embodiment, each wheel frame 3 on both sides of the truck bed 1 has a wheel 4 on its outer side. A pair of wheels 4 are provided, with the two corresponding wheels 4 aligned front and back along the centerline of the wheel frame 3. The bottom of the outer side of the two vertical rods 32 on the wheel frame 3 is provided with mounting shafts 35 corresponding to the wheels 4. The wheels 4 are rotatably mounted on the outer side of the corresponding vertical rods 32 through the mounting shafts 35. The two corresponding wheels 4 are mirror images of each other front and back along the axis of the bushing 34. This design allows the wheel frame 3 to swing up and down around the rotation axis 22 of the beam 2 under the drive of the wheels 4 when it encounters an obstacle while the dump truck is traveling. This swinging motion reduces the vertical displacement caused by the road obstacle, thus preventing the dump truck 1 from swinging too much. This reduces the probability of the dump truck overturning on uneven roads and improves its stability.

[0026] The main beam 2 includes a beam body 21. At both ends of the beam body 21, there is a pair of connecting plates 23 corresponding to the truck bed 1. The connecting plates 23 are located on the upper side of the beam body 21, and their bottom ends are fixedly connected to the beam body 21. The truck bed 1 is fixedly installed between the corresponding two connecting plates 23. The rotating shaft 22 is arranged in pairs at both ends of the beam body 21 outside the connecting plates 23. The inner end of the rotating shaft 22 is fixedly connected to the corresponding end of the beam body 21. When the rotating shaft 22 rotates relative to the wheel frame 3, the crossbeam will rotate synchronously, thereby driving the truck bed 1 to rotate synchronously along the axis of the rotating shaft 22 through the truck bottom frame 11, thus realizing the tipping function of the tipper truck, so that it can unload goods better during material transportation.

[0027] A corresponding chassis frame 11 is provided between the main beam 2 and the truck bed 1. The truck bed 1 is installed on the main beam 2 through the chassis frame 11. The upper end of the chassis frame 11 is fixedly connected to the bottom surface of the truck bed 1. A pair of mounting seats 12 corresponding to the main beam 2 are provided at the bottom of the chassis frame 11. The chassis frame 11 is fixedly installed on the main beam 2 through the mounting seats 12. The safety buckle 61 corresponding to the safety lock 6 is fixedly installed on the bottom of the front side of the chassis frame 11. The chassis frame 11 increases the load-bearing area at the bottom of the truck bed 1, improves the load-bearing capacity of the truck bed 1, and makes it more stable and less prone to deformation.

[0028] The tow bar 5 is divided into two sections, namely the front bar 51 and the rear bar 52. The tail of the rear bar 52 is rotatably connected to the main beam 2, and the axis of rotation between the two is parallel to the main beam 2. The tail of the front bar 51 is rotatably connected to the front of the rear bar 52, and the axis of rotation between the front bar 51 and the rear bar 52 is perpendicular to the plane containing the axis of rotation between the rear bar 52 and the main beam 2. This arrangement allows the workers to flexibly adjust the direction when the dump truck 1 is tipped over for unloading. The front end of the front bar 51 extends towards the front side of the dump truck 1, and the safety lock 6 is installed on the top surface of the front bar 51, making the dump truck more stable during driving.

[0029] The front end of the tow bar 5 is provided with a connector 53 for external connection. The connector 53 includes, but is not limited to, the following two structures:

[0030] The first type includes a U-shaped fork head, the tail of which is connected to the tow bar 5. The fork head has a pair of through holes that are connected in series, and a connecting pin assembly that connects them in series is provided in the through holes. The tow bar 5 is connected to the corresponding power vehicle through the cooperation of the fork head and the connecting pin assembly. This structure is relatively simple and easy to manufacture.

[0031] The second type includes a tractor unit and fasteners. The tail of the tractor unit is connected to the tow bar 5, and the fasteners are located on top of the tractor unit. The tow bar 5 is connected to the corresponding power vehicle through the cooperation of the tractor unit and the fasteners. This structure is more robust and flexible.

[0032] The safety lock 6 includes a latch 62 and a connecting block 63. The latch 62 is U-shaped, with its top crossbeam mounted on the tow bar 5. Its rear side has a corresponding slot for engaging with the safety latch 61. The front end of the truck bed 1 can be detachably secured to the safety latch 61 through the engagement of the slot. Two posts of the latch 62 extend downwards from the left and right sides of the tow bar 5, and the middle of the two posts is rotatably connected to the tow bar 5. The latch 62 can rotate back and forth around its pivot point with the tow bar 5, thereby enabling the slot to engage and disengage with the safety latch 61. The front side of the latch 62 has an upward-opening U-shaped connecting block 63, the bottom of which is rotatably connected to... On the tow bar 5, a corresponding pedal is provided at the top of the front vertical plate of the connecting block 63. The top of the rear vertical plate of the connecting block 63 is rotatably connected to the upper front of the latch 62. When force is applied to the pedal, the lever principle is used to pull the upper end of the latch 62 forward, thereby disengaging the slot and the safety buckle 61. On the other side of the latch 62 at the bottom of the tow bar 5, opposite to the truck bed 1, there is a tension spring 64. The front end of the tension spring 64 is fixedly connected to the bottom surface of the tow bar 5. The bottom ends of the two pillars of the latch 62 extend from the lower side of the tow bar 5 and are connected to the rear end of the tension spring 64. When the slot at the top of the latch 62 flips forward under the action of the connecting block 63, it disengages from the safety buckle. When buckle 61 is engaged, the rear end of tension spring 64 is simultaneously subjected to a backward force transmitted from the bottom end of buckle 62. Tension spring 64 extends under this force, and due to its own elasticity, it generates an inward reaction force. Therefore, tension spring 64 applies a forward pulling force to the bottom end of buckle 62. Under the action of tension spring 64, the top end of buckle 62 rotates backward around its rotational connection axis with tow bar 5, causing the slot to automatically return to the position corresponding to the safety buckle 61. The rear side of buckle 62 above the slot is designed as a slope that gradually slopes backward from top to bottom. Thus, when the truck bed 1 is tilted and restored, its bottom end and the slope above the slot... Upon initial contact, the inclined plane converts the portion of the force applied to the truck bed 1 into forward thrust, thereby causing the latch 62 to open automatically. The safety latch 61 then automatically slides into the slot, achieving automatic engagement between the safety latch 61 and the latch 62. A corresponding safety plate 65 is provided on the shaft connecting the connecting block 63 and the latch 62. When the safety plate 65 is secured between the tow bar 5 and the latch 62, the latch 62 is locked, preventing it from rotating freely with the tow bar 5, thus causing instability in the truck bed 1. When the safety plate 65 opens, the rotation between the latch 62 and the tow bar 5 is unlocked, and applying force causes the tow bar 5 to flip back and forth.

[0033] In use, the materials to be transported are loaded onto the dump truck 1. The dump truck is connected to the power vehicle via the connector 53 at the front end of the tow bar 5. The power vehicle can then tow the dump truck to transport the materials. During normal operation, the safety lock 6 is in a locked, closed state. When unloading is required at the designated location, first, the safety plate 65 of the safety lock 6 is activated to unlock it. Then, the pedal is pressed, disconnecting the safety lock 6 from the safety buckle 61. Force is then applied to the dump truck 1 via the handle 7, causing it to rotate around the beam 2. The moving shaft 22 flips backward to unload the goods from the truck bed 1. Simultaneously, the pedal is released, and the safety lock 6 returns to its original position under the action of the tension spring 64. During the unloading process, the direction of the goods falling can be flexibly changed by the towing bar 5. After unloading is completed, force is applied to the truck bed 1 to make it flip forward and return to its original position. The safety buckle 61 automatically engages with the safety lock 6 under the action of the weight and inertia of the truck bed 1. The safety plate 65 is moved to lock it. In this way, one round of transportation and unloading of the truck bed 1 is completed, and it can be used for a new round of transportation.

[0034] This utility model dump truck improves the stability of the dump truck bed 1 through the rotational cooperation of the wheel frame 3 and the main beam 2, reducing the amplitude of bumps caused by uneven road surfaces and the possibility of tipping over due to road obstacles, making it more stable and safer. The rotational cooperation of the front and rear sections of the tow bar 5 improves the steering flexibility of the dump truck during unloading, making unloading more convenient and faster. The safety lock 6 and the safety buckle 61 work together to prevent the dump truck bed 1 from moving arbitrarily during driving, thereby improving its stability during driving. The cooperation between the various mechanical components of the safety lock 6 makes it more automatic and less labor-intensive to use.
