Description
Technical Field
[0001] The utility model relates to the technical field of electric flat cars, in particular to an electric flat car bearing table with a protective structure. Background Art
[0002] Electric flat cars are a type of transport equipment, usually used to move goods or materials in factories, warehouses, logistics centers, etc. They use an electric drive system, which can easily move large amounts of goods and reduce the labor intensity of operators.
[0003] The existing electric flat cart moves on a fixed track. When the electric flat cart stops suddenly, large or high goods are easily slipped off the surface of the electric flat cart due to inertia. At the same time, the heights of the shelves in the warehouse or factory may be different, and sometimes the goods need to be placed high or low. The height of the load-bearing surface of the existing electric flat cart is relatively fixed, which is not convenient for loading and unloading goods on shelves at different heights. For this reason, we propose an electric flat cart load-bearing surface with a protective structure. Utility Model Content

[0025] Reference Figure 1 and Figure 4 As shown, an electric flat car bearing table with a protective structure includes an electric flat car body 1, a lifting mechanism 2 arranged at the upper end of the electric flat car body 1 and a bearing table 3 arranged at the upper end of the lifting mechanism 2, a storage groove 5 is opened at the upper end of the bearing table 3, and electric push rods 6 are fixedly installed at the four corners of the bottom end of the storage groove 5, the output ends of the two electric push rods 6 on the front and rear sides are fixedly connected with brackets 7, an adjustment groove 8 is opened through the front side of the bracket 7, a second motor 9 is fixedly installed inside the rear adjustment groove 8, a second bidirectional threaded rod 10 is fixedly connected to the output end of the second motor 9, and third sliders 11 are rotatably connected at both ends of the second bidirectional threaded rod 10, a guide rod 12 is fixedly connected inside the front adjustment groove 8, and two fourth sliders 13 are slidably connected to the outer surface of the guide rod 12, and a limiting block 14 is fixedly connected between the third slider 11 and the fourth slider 13.
[0026] Furthermore, the limit block 14 is perpendicular to the travel direction of the flatbed trolley. The bracket 7 and the limit block 14 are stored in the storage slot 5 when not in use, and the upper end thereof is flush with the upper end of the load-bearing platform 3. The bracket 7 can be pushed out of the storage slot 5 by the electric push rod 6. The second motor 9 drives the second bidirectional threaded rod 10 to rotate, which can drive the third slider 11 and the fourth slider 13 to slide along the adjustment slot 8, so that the two limit blocks 14 are limited close to the two sides of the cargo, which can prevent the cargo from sliding off the surface of the electric flat cart when the electric flat cart stops suddenly.
[0027] Reference Figure 2 As shown, the lifting mechanism 2 includes a fixed base 201 fixedly connected to the upper end of the electric flat car body 1, and two first bidirectional threaded rods 202 are rotatably connected between the left and right inner walls of the fixed base 201. Both ends of the first bidirectional threaded rod 202 are threadedly connected to a first slider 203, and the upper end of the first slider 203 is fixedly connected to two first fixed plates 204.
[0028] Two slide grooves 4 are provided at the lower end of the supporting platform 3, a sliding rod 206 is fixedly connected inside the slide groove 4, two second sliders 207 are slidably connected to the outer surface of the sliding rod 206, and two second fixed plates 208 are fixedly connected to the lower end of the second slider 207.

The two support rods 205 on the front and rear sides are cross-arranged, and the two first sliders 203 on the front and rear sides can be made close to each other by rotating the first bidirectional threaded rod 202, thereby pushing the load-bearing platform 3 to be lifted through the support rod 205, and the height of the load-bearing platform 3 can be adjusted, which is convenient for loading and unloading goods on shelves at different heights.
[0030] Reference Figure 3 As shown, a first pulley 209 is fixedly connected to the middle of the outer surface of the first bidirectional threaded rod 202, a first motor 2010 is fixedly installed on the inner bottom end of the fixed base 201, and a second pulley 2011 is fixedly connected to the output end of the first motor 2010.

Driven by the transmission belt 2012, the two first pulleys 209 rotate the second pulley 2011 synchronously, thereby driving the two first bidirectional threaded rods 202 to rotate synchronously.
[0031] Working principle: When the device is in use, first place the goods at the center of the upper end of the load-bearing platform 3, and connect the electric push rod 6 to the power supply, push the bracket 7 out of the storage slot 5 through the electric push rod 6, and then connect the second motor 9 to the power supply, and use the second motor 9 to drive the second bidirectional threaded rod 10 to rotate, thereby driving the third slider 11 and the fourth slider 13 to slide along the adjustment slot 8, so that the two limit blocks 14 are close to the two sides of the goods for limit, and when the limit blocks 14 are in contact with the surface of the goods, they can be transported. When the height of the load-bearing platform 3 needs to be adjusted, connect the first motor 2010 to the power supply, and drive the second pulley 2011 to rotate through the first motor 2010. Driven by the transmission belt 2012 and the two first pulleys 209, the two first bidirectional threaded rods 202 will rotate synchronously, thereby driving the two first sliders 203 on the same side to move closer or farther away from each other, so as to realize the rising or falling of the load-bearing platform 3.
