DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] The present invention provides a wall panel transport vehicle, the base frame of which is close to the ground. The wall panels do not need to be manually carried to a certain height. The vehicle only needs to reach the position of the wall panels placed on the ground and start the device on the vehicle body to lift and transport the wall panels.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1-8 As shown, the present invention provides a wall panel transport vehicle, including a base frame 1, wherein the base frame 1 is partially used to hold the wall panel 13 to be transported, and the base frame 1 includes a longitudinal portion 1-1 and a transverse portion 1-2 respectively connected to both ends of the longitudinal portion 1-1 and perpendicular to the longitudinal portion 1-1. The sizes of the longitudinal portion 1-1 and the transverse portion 1-2 are set according to the standard size of the wall panel 13 to be transported. The transverse portion 1-2 can be slightly smaller than the length of the wall panel 13, and the longitudinal portion 1-1 can be slightly larger than the width of the wall panel 13. The front end of the transverse portion 1-2 is connected to the first driving mechanism 2, and the front end of the first driving mechanism 2 is rotatably connected to the first running wheel 3; the initial state of the transport vehicle is that the lower end of the transverse portion 1-2 is close to the ground, the first running wheel 3 is extended forward, and the transverse portion 1-2 and the first running wheel 3 are on the same horizontal line; a first connecting rod 4 is fixedly provided at the center of the longitudinal portion 1-1, and the first connecting rod 4 is provided with a long square tube structure with an open side, and the opening is opposite to the first running wheel 3. A second driving mechanism 5 is provided above the first connecting rod 4 in a direction opposite to the first running wheel 3, and a second connecting rod 4 is provided below the first connecting rod 4 to be rotatably connected to the first connecting rod 4. Connecting rod 7, first pin holes 4-1 are set on the two side walls of the first connecting rod 4, the second connecting rod 7 is connected to the first connecting rod 4 through the first rotating shaft 4-2, and the second running wheel 6 is connected to the lower part of the other end of the second connecting rod 7. A second running wheel 6 and the two first running wheels 3 at the front end form a triangular structure to ensure the stability of the vehicle body to achieve the purpose of transportation. The other end of the second driving mechanism 5 is rotatably connected to the second connecting rod 7, and second fixing plates 7-1 are fixed on both sides of the second connecting rod 7. A second pin hole 7-2 is opened above the second fixing plate 7-1, and the second driving mechanism 5 is connected to the second fixing plate 7-1 through the second rotating shaft 7-3.

[0031] Two bottom plates 9 are provided at the bottom end of the longitudinal portion 1-1 on one side facing the first walking wheel 3. The function of the bottom plates 9 is to place one end of the transported wall panel 13 on the two bottom plates 9 to prevent it from falling. A clamping device 8 is provided on the inner side of the front end of the transverse portion 1-2, and the other end of the wall panel 13 is placed on the clamping device 13, so that the front and rear ends of the wall panel can be fixed on the vehicle.

[0032] Specifically, a handlebar 10 is further provided above the second running wheel 6, and the handlebar 10 is used to push the transport vehicle. The handlebar 10 includes a handlebar 10-1 and a first handle 10-2 installed on the upper end of the handlebar 10-1. The handlebar 10 is installed above the second running wheel 6 through a handlebar base 10-3. The second connecting rod 7 is fixedly connected to the third connecting rod 11 fixed on the handlebar base 10-3. The third connecting rod 11 is provided with a square tube structure with one less opening, and the opening direction is opposite to the opening direction of the first connecting rod 4.

[0033] Specifically, two parallel second connecting rods 7 are provided to enhance stability during operation of the second drive mechanism 5. The other ends of the two second connecting rods 7 are connected to the upper and lower portions of the third connecting rod 11, respectively, and the other ends are rotationally connected to the first connecting rod 4. A third pin hole 4-3 is provided below the first pin hole 4-1, and the second connecting rod 7 is connected to the first connecting rod 4 via a third rotating shaft 4-4. This ensures that the second drive mechanism 5 connected to the first connecting rod 4 and the two second connecting rods 7 are both rotationally connected. When the second drive mechanism 5 is ejected, the base frame 1 can be raised as the reaction force between the second running wheel 6 and the ground increases.

[0034] Specifically, in order to improve the automated control performance of the transport vehicle, a power supply unit 14 is installed on one side and a power unit 15 is installed on the other side of the back side of the longitudinal part 1-1 of the base frame 1; a controller 16 is installed on the side of the handlebar base 10-3; and outer covers are provided on the outside of the power supply unit 14, the power unit 15, and the controller 16.

[0035] Specifically, the transverse portion 1-2 includes a first horizontal crossbar 1-21 and a first inclined crossbar 1-22. The first horizontal crossbar 1-21 is horizontally disposed, while the first inclined crossbar 1-22 is inclined. The horizontal length of the first horizontal crossbar 1-21 is greater than the horizontal length of the first inclined crossbar 1-22. One end of the first horizontal crossbar 1-21 and the first inclined crossbar 1-22 are connected to the upper and lower ends of the longitudinal portion 1-1, and the other ends are connected together by a first fixing plate 12. The angle between the ends connected by the first fixing plate 12 is acute. This ensures that the base frame 1 is wide at the rear and narrow at the front, making it easy to load the transported wall panels 13.

[0036] Specifically, the outer structure of the first fixed plate 12 is an acute-angled triangle, and the three corners are respectively connected to the first drive mechanism 2, the first horizontal cross bar 1-21 and the first walking wheel 3. The angle between the first drive mechanism 2 and the first fixed plate 12 is an obtuse angle. When the first drive 2 is ejected, the corner connected to the first drive mechanism 2 extends forward. At this time, the corner connected to the first walking wheel 3 drives the first walking wheel 3 to move back until the first walking wheel 3 moves to the obliquely below the first horizontal cross bar 1-21, and the entire base frame 1 is slightly lifted.

[0037] Specifically, the first drive mechanism 2 is connected to the first inclined crossbar 1-22, and the clamping device 8 is mounted on the first horizontal crossbar 1-21. The clamping device 8 includes a fourth connecting rod 8-1, which is vertically fixed to the first horizontal crossbar 1-21. L-shaped hook plates 8-2 are provided on both sides of the fourth connecting rod 8-1, which rotate downward and inward. When the wall panel 13 is mounted on the vehicle, it is secured by the hook portion of the hook plate 8-2. Second handles 8-3 are fixed on both sides of the fourth connecting rod 8-1, which face upward and outward. If the width of the wall panel 13 interferes with the width of the longitudinal portion 1-1 of the base frame 1, manually rotating the second handles 8-3 will reduce the interference and facilitate the mounting of the wall panel 13.

[0038] Specifically, in the embodiment of this solution, the first drive mechanism 2 and the second drive mechanism 5 are both oil cylinders, wherein the ejection portion of the first drive mechanism 2 is connected to the first fixing plate 12 ; the ejection portion of the second drive mechanism 5 is connected to the first connecting rod 4 .

[0039] Specifically, in order to reduce the weight of the vehicle body and facilitate transportation, the bottom plate 9 has an outer structure of an ear plate, and the length of the bottom plate 9 extending outside the longitudinal portion 1-1 is not more than 20 cm.

[0040] Specifically, the height of the first connecting rod 4 is greater than the height of the longitudinal portion 1 - 1 .

[0041] Workflow:

[0042] Initial state: the first horizontal crossbar 1-21 is close to the ground, the first running wheel 3 is extended forward, and the first running wheel 3 and the first horizontal crossbar 1-21 are on the same horizontal line (see Figure 1-3 ) Neither the first drive mechanism 2 nor the second drive mechanism 5 extends.

[0043] Wall Panel Loading: Move the transport vehicle to wall panel 13. One end of wall panel 13 is supported by base plate 9. The other end of wall panel 13 is manually adjusted using clamping device 8, and hook plate 8-2 supports the other end. When loading the wall panel onto the vehicle, since base frame 1, base plate 8, and hooks of hook plate 8-2 are all positioned close to the ground, there's no need to raise wall panel 13, ensuring safety and reducing the need for manual work.

[0044] The process of lifting the base frame 1: During the transportation process, the base frame 1 needs to be slightly raised as a whole, and then the transport vehicle is started to move. The first driving mechanism 2 is started, and the first running wheel 3 changes from the forward extended state to the backward movement, until the first running wheel 3 moves to the oblique lower part of the first horizontal cross bar 1-21, and the first running wheel 3 lifts the front 1 of the base frame; the second driving mechanism 5 is started, and the reaction force between the second running wheel 6 and the ground is used to push out the oil cylinder of the second driving mechanism 5, and the rear part of the base frame 1 is raised and stops directly at the same horizontal line as the front. In this way, the base frame is fully raised and the transport vehicle is started (see details). Figure 4-6 ).

[0045] After the base frame 1 of the embodiment of the present invention is lifted, that is, during the process of transporting the wall panels, it only needs to be raised 3 cm from the ground, with a low center of gravity and stable transportation, which greatly improves safety performance.

[0046] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
