Description

Technical Field

[0001] This utility model relates to the field of electric flatbed truck technology, specifically an electric flatbed truck used for wind turbine assembly. Background Technology

[0002] Electric flatbed trucks are transportation vehicles powered by batteries and driven by motors for hauling goods or people. Electricity, as an important energy source that is environmentally friendly, clean, and has a high conversion rate, is used to drive the upgrading of transportation vehicles, promote the low-carbon development of the transportation industry, reduce transportation costs, save energy, and protect the environment. With the development of modern science and technology, the usage rate of electric flatbed trucks is increasing.

[0003] Because current electric flatbed carts cannot automatically flip and unpile during use, which can easily affect work efficiency, people have set up inclined storage boards on electric flatbed carts and used them in conjunction with flipping mechanisms to achieve automatic unpile functionality, thereby effectively avoiding the need for manual labor in unloading. For example, Chinese utility model patent with announcement number CN215971675U specifically discloses an electric flatbed cart with automatic unloading.

[0004] However, in actual use, people have found that because the surface of the electric flatbed truck is relatively smooth, when transporting fan assembly parts, if the flatbed is tilted and flipped directly, the box will shake violently after falling, which can easily cause wear on the parts and is not conducive to improving the stability during unloading. Utility Model Content

A single-axis motor is mounted on one side of the support plate, and a first lead screw is fixedly connected to the output shaft of the single-axis motor. The movable seat is connected to the first lead screw. A dual-axis motor is mounted on the movable seat. Second lead screws are fixedly connected to the output shafts on both sides of the dual-axis motor. A first clamping plate is connected to the second lead screw. A second clamping plate is slidably connected to the first clamping plate. A locking element connects the second clamping plate to the first clamping plate.

[0008] Preferably, the support plate has a groove on the side near the base, and the slider is slidably connected to the inside of the groove; this facilitates the improvement of the stability of the slider on the support plate.

[0009] Preferably, the bearing plate is provided with a plurality of sliding grooves, the first lead screw is disposed inside the sliding groove, and the movable seat is slidably connected to the inner wall of the sliding groove; this facilitates the improvement of the stability of the fan assembly parts during unloading.

[0010] Preferably, both the first clamping plate and the second clamping plate row are provided with a plurality of through slots, which are distributed in a rectangular array, and the locking member passes through the through slots; this facilitates adjustment of the distance between the second clamping plate and the movable seat.

[0011] Preferably, the first clamping plate has a connecting groove at one end away from the movable seat, and one end of the second clamping plate is slidably connected to the inside of the connecting groove. The cross-section of the second clamping plate is "L"-shaped, which helps to improve the stability of the second clamping plate on the first clamping plate.

[0012] Preferably, the locking element consists of a screw and a nut; this facilitates improving the efficiency of adjusting the position of the second clamping plate.

[0013] Preferably, one end of the base has a slot, and the end of the support plate away from the movable seat corresponds to the slot; this facilitates the movable seat to move the fan assembly parts out of the base.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This electric flatbed trolley for wind turbine assembly uses a movable seat, a first clamp, and a second clamp on the support plate to fix the wind turbine assembly parts, improving the stability of the parts on the electric flatbed trolley. It also provides guidance when the support plate is unloaded, preventing the parts from falling and shaking violently due to excessive speed during sliding. The first clamp can also be driven by a dual-axis motor to move the second lead screw closer or further apart. The first clamp can also be repositioned on the first clamp through locking components and through slots, allowing for free adjustment according to parts of different sizes. The structure is simple and easy to operate. While improving the stability of the parts, it saves operation time and helps reduce the loss of wind turbine assembly parts during transportation.

[0026] More specifically, by creating a groove 10 on the support plate 5 and sliding it to connect with the slider 9, the sliding trajectory of the slider 9 can be guided, which helps to improve the stability of the slider 9 on the support plate 5.

[0027] In this utility model, a plurality of sliding grooves 11 are provided on the support plate 5, the first lead screw 8 is disposed inside the sliding groove 11, and the movable seat 6 is slidably connected to the inner wall of the sliding groove 11.

[0028] More specifically, by creating a groove 11 on the support plate 5 and slidingly connecting it to the movable seat 6, the stability of the movable seat 6 on the support plate 5 can be improved, which facilitates the improvement of the stability of the fan assembly parts during unloading.

[0029] In this utility model, the first clamping plate 14 and the second clamping plate 15 are each provided with a plurality of through slots 16, which are distributed in a rectangular array, and the locking member 18 passes through the through slots 16.

[0030] More specifically, by opening multiple through slots 16 on the first clamping plate 14 and the second clamping plate 15, the position of the second clamping plate 15 on the first clamping plate 14 can be adjusted according to people's needs, so as to facilitate the adjustment of the distance between the second clamping plate 15 and the movable seat 6.

Then, the locking piece 18 is used to fix it through the through groove 16 on the first clamping plate 14 and the second clamping plate 15, thus accommodating boxes of different sizes. After the drive mechanism 3 moves the base 1 to the appropriate position, it controls the electric telescopic rod 2 to extend upwards. As the electric telescopic rod 2 extends, the slider 9 will... Slide the support plate 5 to one side inside the groove 10. Since one end of the support plate 5 is rotatably connected to the base 1, the support plate 5 will tilt towards the groove 4. At this time, start the single-axis motor 7 installed on one side of the support plate 5. With the cooperation of the slide 11 and the first lead screw 8, drive the moving seat 6 to move towards the groove 4. After the first clamping plate 14 and the second clamping plate 15 drive the box to move into the groove 4, the distance between the second clamping plates 15 is controlled by the dual-axis motor 12 to release the fixation of the box, thereby reducing the impact generated by the box during unloading.
