Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, and in particular to a flatbed transport vehicle with a hydraulic lifting system. Background Technology

[0002] Flatbed trucks, also known as construction machinery transport vehicles, flatbed trucks, or low-bed trucks, are mainly used to transport non-detachable objects such as excavators, loaders, and harvesters. However, they are also commonly used for transporting longer items like steel bars and pipes over long distances. Although there are some specialized steel bar transport vehicles available, these are primarily used for transferring steel materials at production or construction sites and do not meet road driving standards, especially on highways.

[0003] When unloading items such as steel bars and pipes transported by existing flatbed trucks, the weight of these items usually necessitates the use of lifting equipment at the unloading site. This coordination of lifting equipment often leads to delays in unloading, requiring the flatbed truck driver to wait at the unloading site, which is time-consuming. Sometimes, the unloading area is too small to accommodate the lifting equipment simultaneously.

[0004] To address the problems in existing technologies, we propose a flatbed transport vehicle with a hydraulic lifting system. Utility Model Content

[0005] This utility model addresses the problems in the prior art by providing a flatbed transport vehicle with a hydraulic lifting system, which is achieved through the following technical solution: A flatbed transport vehicle with a hydraulic lifting system includes a cab and a chassis. The cab is located at one end of the chassis. A support plate is fixedly connected to the upper surface of the chassis. A receiving groove is formed on the support plate. A discharge push rod is rotatably connected to two side walls of the receiving groove perpendicular to the vehicle's travel direction. A first hinge seat is fixedly connected to the lower surface of the chassis. A first hydraulic cylinder is hinged to the first hinge seat. A second hinge seat is fixedly connected to the side wall of the discharge push rod. The piston rod of the first hydraulic cylinder is hinged to the second hinge seat.

[0006] The present invention is further configured such that: the receiving groove is provided in four sets, from the front to the rear of the vehicle, and the hinge shafts of the four sets of unloading push rods are respectively located on the right side, left side, right side and left side of the receiving groove.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings.

[0014] like Figure 1-8 As shown, this utility model discloses a flatbed transport vehicle with a hydraulic lifting system, including a cab 1 and a chassis 2. The cab 1 is located at one end of the chassis 2. A support plate 3 is fixedly connected to the upper surface of the chassis 2. A receiving groove 4 is formed on the support plate 3. Unloading push rods 5 are rotatably connected to the two side walls of the receiving groove 4 perpendicular to the vehicle's driving direction. A first hinge seat 6 is fixedly connected to the lower surface of the chassis 2. A first hydraulic cylinder 7 is hinged to the first hinge seat 6. A second hinge seat 8 is fixedly connected to the side wall of the unloading push rod 5. The piston rod of the first hydraulic cylinder 7 is hinged to the second hinge seat 8. By setting the unloading push rod 5 at the bottom of the support plate 3, automatic unloading of goods such as steel bars and steel pipes can be achieved, eliminating the need to coordinate lifting equipment at the unloading site, improving unloading efficiency, and better adapting to confined spaces.

[0015] The receiving trough 4 is equipped with four sets, from the front to the rear of the vehicle. The hinge shafts of the four sets of unloading push rods 5 are respectively located on the right, left, right, and left sides of the receiving trough 4. The unloading push rods 5 are arranged alternately, which can realize unloading from both the left and right sides. When there is enough space on the left side of the flatbed truck for unloading, unloading can be done on the left side of the flatbed truck. When there is enough space on the right side of the flatbed truck for unloading, unloading can be done on the right side of the flatbed truck. The specific unloading method can be selected according to the unloading site conditions.

[0016] To facilitate unloading to both sides of the flatbed transport vehicle, the unloading push rod 5 is configured as a telescopic push rod. The unloading push rod 5 includes a support rod 9 and a telescopic rod 10. A second hinge seat 8 is mounted on the support rod 9. The telescopic rod 10 is slidably connected to the support rod 9. A second hydraulic cylinder 11 is hinged to the inner cavity of the telescopic rod 10, and the piston rod of the second hydraulic cylinder 11 is hinged to the inner side wall of the support rod 9. When unloading to both sides of the flatbed transport vehicle is required, the piston rod of the second hydraulic cylinder 11 is first controlled to retract, and then the piston rod of the first hydraulic cylinder 7 is controlled to extend, pushing the support rod 9 to rotate, thereby pushing the goods to both sides of the supporting flatbed 3.

[0017] A third hinge seat 12 and a fixing plate 13 are fixedly connected to the two side walls of the supporting plate 3, which are parallel to the vehicle's direction of travel. A connecting plate 14 is hinged to the third hinge seat 12, and a column 15 is fixedly connected to the side wall of the connecting plate 14. When the connecting plate 14 is in contact with the side wall of the supporting plate 3, the lower end face of the column 15 is in contact with the upper end face of the supporting plate 3. The connecting plate 14 has a through hole 16 through which the fixing plate 13 passes, and the fixing plate 13 has a fixing hole 17. A wedge 18 for fixing the connecting plate 14 is provided in the fixing hole 17. The column 15 is designed to facilitate the blocking and fixing of goods. The hinged design of the column 15 facilitates unloading. To block and fix goods, the column 15 is rotated upwards, and the fixing plate 13 passes through the through hole 16 on the connecting plate 14 until the column 15 is vertical. Then, the wedge 18 is inserted into the fixing hole 17 to block the connecting plate 14. When unloading, remove the wedge 18 from the fixing hole 17 and rotate the column 15 downwards.

[0018] To prevent vibration during vehicle operation from causing the wedge 18 to detach from the fixing hole 17, an anti-detachment block 20 is provided on the wedge 18. A sliding cavity 19 is formed on the wedge 18, and two sets of anti-detachment blocks 20 are slidably connected in the sliding cavity 19. A spring 21 is fixedly connected between the two anti-detachment blocks 20. Under the elastic force of the spring 21, the two anti-detachment blocks 20 protrude from the side wall of the wedge 18, and the upper end face of the anti-detachment block 20 is in contact with the lower end face of the fixing plate 13. When it is necessary to remove the wedge 18 from the fixing plate 13, simply pinch the two anti-detachment blocks 20, bringing them closer together until the side wall of the anti-detachment block 20 is flush with the side wall of the wedge 18, then the wedge 18 can be removed from the fixing plate 13. The same operation of pinching the two anti-detachment blocks 20 is performed on the wedge 18.

[0019] The terms "left" and "right" used in this application refer to the direction in which the flatbed transport vehicle is traveling, with the front being the direction directly ahead.
