The vehicle body 10 includes a plate body 11 and wheels 12 for supporting the plate body 11. The handle 30 is installed on the left and right sides of the plate body 11. The extension part 20 is movably installed on the front and rear sides of the plate body 11. The extension part 20 can be placed on the vehicle body 10 or overlapped with the ground. The wheels 12 are used to support the movement of the plate body 11. The extension parts 20 are installed at the front and rear ends of the vehicle body respectively. When it needs to be moved, refer to Figure 1 , 2 , rotate the extension part 20 and place it on the vehicle body 10. When "bridge" is needed, refer to Figure 6 , 7 , the vehicle body 10 is placed across the obstacle, and the extension part 20 is rotated to overlap with the ground, so that the trailer can pass through the obstacle. After adopting the device, when "building a bridge", two people do not need to lift and transfer the steel plate many times, thus saving time and labor.
[0031] Preferably, the extension portion 20 includes a flip plate 21 , and the flip plate 21 is hinged to the front and rear end portions of the plate body 11 through hinges 22 , and has a simple structure.
[0032] The articulated member 22 may be a door shaft or a hinge. It should be noted that when a door shaft is used, the door shaft should not be higher than the top plate of the plate body 11 to avoid affecting the passage of the trailer.
[0033] Further, in this embodiment, four wheels 12 can be directly mounted on the bottom of the plate 11. The wheels 12 can be fixed casters or universal casters.
[0034] Embodiment 2:
[0035] In this implementation, see Figure 3 , 4 The extension part 20 includes a flip plate 21 and a swing plate 23. The left and right sides of the swing plate 23 are movably connected to the left and right sides of the plate body 11 through two connecting rods 24. The two connecting rods 24 on each side are parallel to each other. The flip plate 21 is hinged to the end of the swing plate 23 away from the plate body 11 through a hinge 22. The extension part 20 provides a longer inclined ramp by arranging the flip plate 21 and the swing plate 23, which is convenient for the trailer to pass through.
[0036] exist Figure 1 , 2 In the figure, the flip plate 21 and the swing plate 23 are folded. Figure 3 , 4 The middle one is the state when the flip plate 21 and the swing plate 23 are unfolded.
[0037] For details, see Figure 5 Two hinge holes 231 are respectively arranged on both sides of the swing plate 23, and the upper ends of the two connecting rods 24 are respectively hinged to the two hinge holes 231 through pivots. Similarly, threaded holes are respectively arranged on the left and right sides of the plate body 11, and the lower ends of the two connecting rods 24 are respectively hinged to the two hinge holes 231 through bolts. Specifically, after the bolts are tightened with the threaded holes, there is still a gap between the big end of the bolts and the connecting rods 24, so that the holes on the connecting rods 24 can rotate around the bolts. Through the above structure, the swing of the swing plate 23 and the flipping of the flip plate 21 are realized.
[0038] See also Figure 5 Furthermore, the swing plate 23 is a shell structure, and the left and right sides of the swing plate 23 away from the flip plate 21 are respectively provided with extensions 232, and the left and right sides of the front and rear ends of the plate body 11 are respectively installed with support slot seats 13. When the extension portion 20 overlaps with the ground, the extension portion 232 is supported on the support slot seat 13. Through the above structure, see Figure 4When the swing plate 23 is unfolded, the swing plate 23 can be flush with the upper side of the plate body 11, and the extension 232 is supported on the support groove seat 13, which has good stability. In addition, when the swing plate 23 is folded onto the plate body 11, the swing plate 23 of the shell structure can also be sleeved at the end position of the plate body 11.
[0039] For further information, see Figure 4 A horizontal plate 131 is arranged outside the support groove seat 13, a screw 14 is longitudinally screwed and installed on the horizontal plate 131, the wheel 12 is a universal caster, the lower end of the screw 14 is connected and fixed to the top mounting plate of the wheel 12, and a handle 15 is installed on the upper end of the screw 14. Through the above structure, the height adjustment of the plate body 11 is realized, so that obstacles of different heights can be crossed.
[0040] Specifically, the wheel 12 is a universal caster, and a mounting plate is provided on the top of the universal caster. The wheel body is mounted on the lower side of the mounting plate through a bearing, and the lower end of the screw 14 is welded to the mounting plate on the top of the wheel 12. When the screw is rotated by the handle 15, the wheel body does not rotate. Furthermore, the universal caster also has a braking function.
[0041] Furthermore, the support groove seats 13 are also installed in the middle of the left and right sides of the plate body 11, and a horizontal plate 131 is arranged on the outer side of the support groove seat 13. A screw rod 14 is longitudinally screwed and installed on the horizontal plate 131. The lower end of the screw rod 14 is connected and fixed to the top mounting plate of the wheel 12, and a handle 15 is installed on the upper end of the screw rod 14. Through the above structure, when the vehicle body 10 is large in size and the front end of the vehicle body 10 cannot be lifted up to cross obstacles by the handle 30 during use, see Figure 4 , it is necessary to first retract the two front wheels 12 upwards, at this time, push the vehicle body 10, the two front wheels 12 pass over the obstacle, adjust and restore the two front wheels 12, and at this time, the plate body 11 crosses the obstacle. When the vehicle body 10 needs to pass an obstacle, it is necessary to retract the two middle wheels 12 upwards, push the vehicle body 10, the two middle wheels 12 pass over the obstacle, adjust and restore the two middle wheels 12, and then retract the two rear wheels 12 upwards, push the vehicle body 10, and the two rear wheels 12 pass over the obstacle, so that the device passes the obstacle.
[0042] The device can not only be used to "build bridges" to facilitate carts to pass through obstacles, but it can also be used for obstacle-crossing transportation.
[0043] Embodiment three:
[0044] See also Figure 1 The left and right sides of the plate body 11 are provided with mounting seats 31, and the handle 30 is detachably connected to the plate body 11 through the mounting seats 31. When the wrench 30 affects the passage, the wrench can be disassembled.
[0045] There are two ways to detachably install the handle 30. The first is: the mounting seat 31 is welded to the handle 30, and the mounting seat 31 is bolted to the vehicle body 10 by bolts; the second is: the mounting seat 31 with an "Ω" structure is installed on both sides of the vehicle body 10, and the longitudinal section of the lower end of the handle 30 can be movably inserted into the mounting seat 31 with the "Ω" structure.
[0046] The working principle or action process of the utility model is as follows:
[0047] When in use, when the vehicle body is small, the front end of the vehicle body 10 can be lifted up through the handle 30, so that the vehicle body 10 can be placed across the obstacle, and the extension part 20 can be unfolded and overlapped with the ground, so that the trailer can pass through the obstacle.
[0048] When the vehicle body 10 is large in size, see Figure 4 , you need to first retract the two front wheels 12 upwards, at this time, push the vehicle body 10, the two front wheels 12 pass the obstacle, adjust and restore the two front wheels 12, at this time, see Figure 6 , 7 , the vehicle body 10 is across the obstacle, and the extension portion 20 is unfolded to make the extension portion 20 overlap with the ground, thereby facilitating the trailer to pass through the obstacle.
[0049] When the vehicle body 10 needs to pass an obstacle, the two middle wheels 12 need to be retracted upwards, and the vehicle body 10 is pushed at this time, and the two middle wheels 12 pass over the obstacle, and the two middle wheels 12 are adjusted and restored, and then the two rear wheels 12 need to be retracted upwards, and the vehicle body 10 is pushed, and the two rear wheels 12 pass over the obstacle, so that the device passes the obstacle.
