Description

Technical Field

[0001] The present invention relates to the technical field of transport vehicles, in particular to a dump truck and a vehicle. Background Art

[0002] Dump trucks are divided into rear-flip dump trucks and side-flip dump trucks. Compared with rear-flip dump trucks, side-flip dump trucks have the advantages of fast unloading speed, high efficiency, wide transportation range and low cost. However, when existing side-flip vehicles are unloading, they are mainly realized by rolling over the carriage, which causes the center of gravity of the vehicle to shift when rolling over. The greater the rollover angle of the carriage, the greater the center of gravity shift of the vehicle. In particular, when unloading is fast, the center of gravity of the vehicle suddenly shifts, which often causes the entire vehicle to roll over, thereby reducing the safety of unloading of existing side-flip vehicles. In addition, when the carriage in the prior art rolls over, the dumping port is located directly above the wheel, and the cargo will be unloaded along the slope to a place close to the frame, and the wheels will be buried, making the vehicle unable to drive. The driver needs to operate a two-way hydraulic cylinder at the rear of the frame, commonly known as a shifting top, to move the vehicle to the left or right to move away from the accumulated cargo, so that the vehicle can be completely freed.

Specifically, the reinforcing bracket 14 includes a support beam 141 and a reinforcing structure 142. A plurality of reinforcing structures 142 are arranged at intervals along the length direction of the support beam 141 and are fixed to the support beam 141. The reinforcing structure 141 is W-shaped as a whole, which can not only allow the first telescopic member 50 to have sufficient space for movement, but also allow the dump car to have better stability when placed on the ground. In this embodiment, the dump car also includes a hook, which is fixedly welded to the column 13, which can facilitate lifting, and will not be described in detail here.

[0075] For further information, please refer to Figure 1 and Figure 2 The side door assembly 30 further includes a guardrail 32, which is fixedly disposed on the column 13, and the movable door 31 is rotatably disposed below the guardrail 32.

[0076] Furthermore, the first telescopic member 50 and the second telescopic member 60 are both hydraulic cylinders. Specifically, in this embodiment, the first telescopic member 50 is a one-way hydraulic cylinder, and the second telescopic member 60 is a two-way hydraulic cylinder. Fig.15As shown, the dump truck body also includes a hydraulic system 120, which includes a hydraulic oil tank 1201, a hydraulic pump 1202, a control valve 1203 and a hydraulic pipeline 1204. The hydraulic pipeline 1204 connects the hydraulic oil tank 1201, the hydraulic pump 1202, the control valve 1203 with the one-way hydraulic cylinder and the two-way hydraulic cylinder in sequence. The control valve 1203 is further provided with a one-way control valve and a two-way control valve. The one-way control valve and the two-way control valve are both provided with three control keys of "lift", "stop" and "lower" for individually controlling the actions of the one-way hydraulic cylinder and the two-way hydraulic cylinder. The hydraulic system 120 is installed on the support seat 11 and can be lifted with the entire truck body.

[0077] Specifically, Fig.16 As shown, the dump truck in this embodiment further includes a ladder 110, which is welded to the outer side of the fixed side plate 43 at the rear of the truck to facilitate the user to check the cargo.

[0078] Specifically, in this embodiment, please refer to Figure 1 and Figure 2 The dump truck compartment also includes a locking structure 130, which includes a first locking member 1301 and a second locking member 1302. The first locking member 1301 is fixedly arranged on the sliding bottom plate 20, and the second locking member 1302 is rotatably arranged on the movable door 31. The first locking member 1301 has a locking groove, and the second locking member 1302 has a locking position engaged with the locking groove and an opening position separated from the locking groove. When in the locking position, the movable door 31 is locked to the sliding bottom plate 20, and when in the opening position, the movable door 31 can be opened.

[0079] The following is a detailed description of the use of the dump truck. When unloading, the telescopic rod of the one-way hydraulic cylinder extends, so that the sliding bottom plate 20 starts to lift with the first rolling body 12 on one side as the support point and the first end of the flip member 80 as the flip center. The sliding bottom plate 20 rotates, driving the bracket 71 to rotate. The push member 75 of the pull rod 72 connected to the bracket 71 starts to push the spring and then push the movable door 31. The rotation of the sliding bottom plate 20 drives the linkage side plate 40 to rotate relative to the slide rod 131. The baffle 42 can ensure that the goods will not leak. At the same time, the two-way hydraulic cylinder contracts, driving the sliding bottom plate 20 to slide relative to the flip member 80, so that the sliding bottom plate 20 extends out of the support seat 11. This arrangement further increases the force on the movable door 31, and the movable door 31 is gradually pushed open until the two-way hydraulic cylinder shrinks to the limit position, and the movable door 31 is opened to the maximum. At this time, the one-way hydraulic cylinder also lifts the sliding bottom plate 20 to the highest position, so that the linkage side plate 40 is parallel to the sliding bottom plate 20, and the efficiency of dumping goods is high. Under the action of gravity, the slide groove 41 of the linkage side plate 40 can slide along the slide rod 131, so that the linkage side plate 40 slides along the sliding bottom plate 20, and the scraper frame 90 can also slide along the sliding bottom plate 20, ensuring that the goods are dumped completely. If there is goods attached to the sliding bottom plate 20, the scraper frame 90 can slide on the sliding bottom plate 20 by telescoping the two-way hydraulic cylinder, so as to scrape the goods.

[0080] After unloading is completed, the two-way hydraulic cylinder is controlled to extend so that the extended sliding base plate 20 slides and retracts relative to the flip member 80, and then the one-way hydraulic cylinder is controlled to retract so that the sliding base plate 20 falls back and is carried on top of the multiple first rolling bodies 12, and the second locking member 1302 is adjusted so that the movable door 31 is locked to the sliding base plate 20 to ensure stability during driving.

[0081] This embodiment also provides a vehicle, which includes a cab and a frame, wherein the cab is connected to the frame, and the vehicle also includes the above-mentioned dump carriage, which is mounted on the frame. Specifically, in this embodiment, the frame includes structures such as wheels and axles. By installing the above-mentioned dump carriage, this vehicle can unload goods quickly and efficiently, and can ensure safety in use.
