Description

Technical Field

[0001] This utility model relates to the field of transport vehicle technology, specifically to a quartz stone slab transport vehicle. Background Art

[0002] Quartz stone slabs are a common building material. Due to their typically large size and heavy weight, they are often transported in warehouses and factories using rail-guided transport vehicles. For example, Chinese patent application CN201721179183.3, entitled "A Highly Stable Rail-Guided Transport Vehicle That Is Not Easily Tilted Over," discloses a transport vehicle base plate. The bottom of the base plate has mounting grooves containing a level sensor and a controller. Two vertically distributed shock absorbers are bolted to the four corners of the top inner wall of the mounting groove, and bearing seats are bolted to the bottom of the shock absorbers. The four bearing seats on the same side are connected to the same rotating shaft via bearings. Universal wheels are mounted at the four corners of the base plate via hydraulic cylinders. When the level sensor detects a tipping on one side, the hydraulic cylinders push the rail-guided transport vehicle level, greatly improving its stability. The two drive motors ensure the transport vehicle's mobility, making its transport more stable.

[0003] However, when using existing transport vehicles to move quartz stone slabs, there is a lack of restraint on the quartz stone slabs. Sometimes, for convenience, multiple quartz stone slabs are stacked on the transport vehicle for transport. Since the surface of some quartz stone slabs is processed to be relatively smooth, the stacked quartz stone slabs are prone to slipping and falling and breaking during the operation of the transport vehicle due to the lack of restraint, resulting in losses. Utility Model Content

[0004] This application provides a quartz stone slab transport vehicle, which can solve the problem that stacked quartz stone slabs are prone to slipping and falling and breaking during the operation of the transport vehicle due to the lack of limiting devices.

[0005] This application provides a quartz stone slab transport vehicle, including a transport vehicle body. A first limiting plate is slidably disposed on each of the front and rear sides of the transport vehicle body along the front-rear direction, respectively used to limit the front and rear ends of the quartz stone slab. The transport vehicle body also has first limiting structures on both the front and rear sides, respectively used to limit or release the sliding of the two first limiting plates. Each first limiting plate has a second limiting plate slidably disposed along the vertical direction, with the two second limiting plates respectively disposed on the side of the two first limiting plates that are close to each other. The first limiting plate is used to limit the upper end of the quartz stone slab. Each of the two first limiting plates is provided with a second limiting structure, which is used to limit or release the sliding of the two second limiting plates respectively. Each second limiting plate is provided with two through holes on the left and right. A rope is provided between each through hole and the transport vehicle body. One end of the rope is connected to the transport vehicle body, and the other end goes up from the left or right end of the quartz stone slab, passes through the through hole and is knotted, which is used to limit the left and right ends of the quartz stone slab.

[0006] In one embodiment, each of the first limiting structures includes a first groove, the length of which is along the front-rear direction. Multiple first limiting protrusions are arranged along the front-rear direction on the bottom of the first groove. Each first limiting protrusion is a right-angled triangular prism, with one right-angled side of each protrusion abutting the bottom of the first groove. The inclined side of each first limiting protrusion is located near the center of the transport vehicle body. Each first limiting plate has a through-hole threaded hole, and a first bolt is threaded into the first threaded hole. The central axis of the first bolt is perpendicular to the bottom of the first groove. By screwing the first bolt into contact with the inclined side of the first limiting protrusion, the sliding of the first limiting plate away from the center of the transport vehicle body is restricted.

[0007] In one embodiment, in the right-angled triangular cross-section of the first limiting protrusion, the included angle of the hypotenuse closest to the bottom of the first groove is any value between 10° and 20°.

[0008] In one embodiment, each second limiting structure includes a second groove, the length direction of which is vertical. Multiple second limiting protrusions are arranged vertically on the bottom of the second groove. Each second limiting protrusion is a right-angled triangular prism, with one right-angled side of each protrusion abutting the bottom of the second groove. The inclined side of each second limiting protrusion is located near the transport vehicle body. Each second limiting plate has a through-hole threaded hole, and a second bolt is threaded into the second threaded hole. The central axis of the second bolt is perpendicular to the bottom of the second groove. By screwing the second bolt into contact with the inclined side of the second limiting protrusion, the upward sliding of the second limiting plate is restricted.

[0009] In one embodiment, in the right-angled triangular cross-section of the second limiting protrusion, the included angle of the hypotenuse closest to the bottom of the second groove is any value between 10° and 20°.

[0010] In summary, the quartz stone slab transport vehicle of this application has the following advantages compared with the prior art:

[0011] (1) When the quartz stone slab is transported by the transport vehicle body, the two first limiting plates can limit the quartz stone slab at the front and rear ends respectively, the two second limiting plates can limit the quartz stone slab at the upper end, and the rope can limit the quartz stone slab at the left and right ends, so that the quartz stone slab will not slip and fall due to the limiting in each direction during the movement of the transport vehicle body, thus improving safety and avoiding loss.

[0012] (2) By adjusting the positions of the first limiting plate and the second limiting plate, as well as adjusting the knot where the rope passes through the through hole, it is possible to limit the quartz stone slabs of different sizes, thicknesses or quantities, which is quite flexible.

[0020] Please see Figure 1 , Figure 2 , Figure 3 A quartz slab transport vehicle includes a transport vehicle body 2. A first limiting plate 4 is slidably disposed on each of the front and rear sides of the transport vehicle body 2 along the front-rear direction. It should be noted that in this invention, the direction in which the transport vehicle body 2 moves forward or backward in the horizontal plane is defined as the front-rear direction, and the direction perpendicular to the front-rear direction in the horizontal plane is defined as the left-right direction. In one embodiment, a first sliding groove 3 is disposed on each of the front and rear sides of the top surface of the transport vehicle body 2 along the front-rear direction. The cross-section of the first sliding groove 3 is convex, and the first limiting plate 4 is slidably connected to the first sliding groove 3. This arrangement provides a more stable sliding effect.

[0021] Please see Figure 1 , Figure 2 , Figure 3Two first limiting plates 4 are used to limit the front and rear ends of the quartz stone slab 1, respectively. The front and rear sides of the transport vehicle body 2 are each provided with a first limiting structure, which is used to limit or release the sliding of the two first limiting plates 4. In one embodiment, each first limiting structure includes a first groove 8. The length direction of the first groove 8 is along the front-rear direction. Multiple first limiting protrusions 9 are arranged and fixedly mounted on the bottom of the groove 8 along the front-rear direction, and the multiple first limiting protrusions 9 are connected end-to-end. The first limiting protrusions 9 are in the shape of right-angled triangular prisms. Each first limiting protrusion 9 has one right-angled side side attached and fixedly connected to the bottom of the groove 8. The inclined side side of each first limiting protrusion 9 is located on the side closest to the middle of the front-rear direction of the transport vehicle body 2. Each of the first limiting plates 4 has a through threaded hole 5 arranged vertically. A first bolt 6 is threadedly connected to the first threaded hole 5. The central axis of the first bolt 6 is perpendicular to the bottom of the first groove 8. By screwing the first bolt 6 to the inclined side of the first limiting protrusion 9, the sliding of the first limiting plate 4 away from the center of the transport vehicle body 2 is restricted. After the quartz stone slab 1 is placed between the two first limiting plates 4 on the transport vehicle body 2, for each first limiting plate 4, the side closer to the center of the transport vehicle body 2 is in contact with the quartz stone slab 1, and the side away from the transport vehicle body 2 is also limited by the inclined surface of the first limiting protrusion 9. Since the first limiting plate 4 can only slide in the front-back direction, the position of the first limiting plate 4 is fixed at this time, so that the two first limiting plates 4 can limit the quartz stone slab 1 on both the front and back sides. This setup is easier to operate. Note that when the first limiting plate 4 is limited by turning the first bolt 6, the first bolt 6 must be in contact with the inclined side of the first limiting protrusion 9.

[0022] Please see Figure 3 In one embodiment, in the right-angled triangular cross section of the first limiting protrusion 9, the included angle of the hypotenuse closest to the bottom of the first groove 8 is any value between 10° and 20°. This setting makes the structure more reasonable and the effect more stable, so that the slope of the hypotenuse of the first limiting protrusion 9 is not too gentle or too steep.

[0023] Please see Figure 1 , Figure 3Each of the first limiting plates 4 has a second limiting plate 10 slidably disposed along the vertical direction. The two second limiting plates 10 are respectively disposed on the side of the two first limiting plates 4 that are close to each other, and are used to limit the upper end of the quartz stone slab 1. In one embodiment, a second sliding groove 7 is disposed along the vertical direction on the side of the two first limiting plates 4 that are close to each other. The cross-section of the second sliding groove 7 is "convex" shaped, and the second limiting plate 10 is slidably connected to the second sliding groove 7. This arrangement makes the sliding effect more stable.

[0024] Please see Figure 3 Each of the two first limiting plates 4 is provided with a second limiting structure, which is used to limit or release the sliding of the two second limiting plates 10. In one embodiment, each second limiting structure includes a second groove 12, the length direction of the second groove 12 is vertical, and a plurality of second limiting protrusions 13 are arranged end to end along the vertical direction at the bottom of the groove 12. The second limiting protrusions 13 are right-angled triangular prisms, and one right-angled side of each second limiting protrusion 13 is fixed to the bottom of the groove 12. The inclined side of each second limiting protrusion 13 is located on the side (lower side) closer to the transport vehicle body 2. Each second limiting plate 10 is provided with a through second threaded hole 15, and a second bolt 16 is threadedly connected to the second threaded hole 15. The central axis of the second bolt 16 is perpendicular to the bottom of the groove 12. By screwing the second bolt 16 into contact with the inclined side of the second limiting protrusion 13, the upward sliding of the second limiting plate 10 is limited. This configuration allows the second limiting plate 10 to limit the quartz stone slab 1 at its upper end, and the limiting position can be adjusted according to the thickness of different quartz stone slabs 1. The operation is simple and the effect is stable.

[0025] Please see Figure 3 In one embodiment, in the right-angled triangular cross-section of the second limiting protrusion 13, the included angle of the hypotenuse closest to the bottom of the second groove 12 is any value between 10° and 20°. This setting results in a more reasonable structure and stable effect, preventing the slope of the hypotenuse of the second limiting protrusion 13 from being too gentle or too steep.

[0026] Please see Figure 1 , Figure 2 , Figure 3Each of the second limiting plates 10 has two through holes 11 on the left and right sides. A rope 14 is provided between each through hole 11 and the transport vehicle body 2. One end of each rope 14 is connected to the transport vehicle body 2 (the rope 14 on the left side is connected to the left side of the transport vehicle body 2, and the rope 14 on the right side is connected to the right side of the transport vehicle body 2). The other end goes upward from the left or right end of the quartz stone slab 1, passes through the through hole 11, and is knotted. This is used to limit the left and right ends of the quartz stone slab 1. The position of the knot after the rope 14 passes through the through hole 11 can be adjusted according to the different sizes of quartz stone slabs 1, which is both flexible and convenient.
