[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figure 1 The present invention relates to a cargo handling trolley, including a platform 1, with casters 5 at the bottom of the platform 1 near the four corners, a push rod 4 fixedly connected to the top of the platform 1, and a limiting mechanism 2 and a driving mechanism 3 provided on the top of the platform 1.

[0023] Specifically, by Figure 2The limiting mechanism 2 includes a vertical plate 201 fixed to the top of the vehicle platform 1. The vertical plate 201 has a through groove 204. Two top blocks 2010 are symmetrically fixedly connected to the top of the vehicle platform 1. Support shafts 209 are rotatably connected between the two top blocks 2010 and the vertical plate 201. Inclined plates 2011 are fixedly sleeved on the outer sides of the two support shafts 209. Multiple arc-shaped anti-slip plates 208 are fixedly fixedly connected at equal distances on the sides of the two inclined plates 2011 that are close to each other. An abutment plate 202 is fixedly connected between the vertical plate 201 and the vehicle platform 1. A U-shaped rod 2015 is fixedly connected to the outer side of the vertical plate 201. Two sliders 20 are symmetrically and movably sleeved on the outer side of the U-shaped rod 2015. 14. The abutment plate 202 is fixedly sleeved on the outer middle of the U-shaped round rod 2015, and the abutment plate 202 is located between the two sliders 2014. The side of the slider 2014 away from the vertical plate 201 is rotatably connected to the side roller 2012. The side of the inclined plate 2011 away from the arc-shaped anti-slip plate 208 is fixedly connected to the U-shaped plate 2013. The side roller 2012 is located between the inclined plate 2011 and the U-shaped plate 2013. Two limiting grooves 205 are symmetrically provided on the vertical plate 201. The limiting rod 203 is fixedly connected in the limiting groove 205. The limiting block 206 is movably sleeved on the outer side of the limiting rod 203. The side rod 207 is fixedly connected between the limiting block 206 and the inclined plate 2011.

[0024] In use, the steel pipe is first placed on top of the vehicle plate 1 and abuts against the abutment plate 202, so that the steel pipe is located between the two sets of arc-shaped anti-slip plates 208. Then, the two sliders 2014 slide along the U-shaped rod 2015 and move closer to each other, driving the two side rollers 2012 to roll on the two inclined plates 2011 respectively, causing the two inclined plates 2011 to rotate. At the same time, the two limiting blocks 206 slide along the outside of the two limiting rods 203 respectively to ensure the stability of the inclined plates 2011 when rotating. Finally, the two sets of arc-shaped anti-slip plates 208 move to clamp the steel pipe, thereby limiting the steel pipe and preventing it from rolling off during transportation.

[0025] Specifically, by Figure 3 The drive mechanism 3 includes a bidirectional lead screw 301 rotatably connected in the through groove 204. Two screw nuts 308 are symmetrically threaded on the outer side of the bidirectional lead screw 301. The two screw nuts 308 are fixedly connected to two sliders 2014 respectively. Two reinforcing plates 304 are symmetrically fixedly connected between the side of the upright plate 201 away from the abutment plate 202 and the car plate 1. A connecting plate 305 is fixedly connected between the two reinforcing plates 304. A drive motor 307 is fixedly installed on the side of the connecting plate 305 near the upright plate 201. A drive shaft 306 is fixedly connected to the drive motor 307. A drive bevel gear 302 is fixedly connected to the end of the drive shaft 306 away from the drive motor 307. A driven bevel gear 303 is fixedly installed on the outer side of the bidirectional lead screw 301. The driven bevel gear 303 meshes with the drive bevel gear 302.

[0026] In use, the drive motor 307 is first started, which drives the drive shaft 306 to rotate and drives the drive bevel gear 302 to rotate. Since the drive bevel gear 302 is meshed with the driven bevel gear 303, it drives the bidirectional lead screw 301 to rotate. Then, through the two lead screw nuts 308, the two sliders 2014 are driven to slide along the U-shaped rod 2015, and finally the movement of the two sliders 2014 is realized.
