[0023] 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.

[0024] Example 1, by Figure 1 The present invention relates to a cargo lifting device for cold chain storage, comprising a base 1, a support mechanism 3 at the bottom of the base 1, a carrying plate 4 at the top of the base 1, a limiting mechanism 2 at the top of the carrying plate 4, two upper hydraulic rods 7 symmetrically fixedly installed between the carrying plate 4 and the base 1, columns 5 fixedly connected to the bottom of the carrying plate 4 near the four corners, and vertical cylinders 6 fixedly connected to the top of the base 1 near the four corners, with each column 5 movably sleeved inside the respective vertical cylinder 6.

[0025] Specifically, by Figure 2-4The limiting mechanism 2 includes a U-shaped frame 201 fixed to the top of the carrying plate 4. An inner plate 202 is fixedly connected to the inner side of the U-shaped frame 201. Multiple support rollers 2013 are rotatably connected to the inner side of the U-shaped frame 201 at equal intervals. A U-shaped plate 208 is fixedly installed at the bottom of the carrying plate 4. A guide post 206 is fixedly connected to the inner side of the U-shaped plate 208. A guide frame 203 is movably sleeved on the outer side of the guide post 206. A positioning ring 207 is fixedly sleeved on the outer side of the guide post 206. The guide frame 203 abuts against the positioning ring 207. Two side shafts 204 are symmetrically rotatably connected to the outer side of the guide frame 203. A limiting plate 2011 is fixedly connected to the end of each side shaft 204 away from the guide frame 203. Two clearance grooves 2016 are symmetrically provided on the top of the U-shaped frame 201. Sliding grooves 2017 are provided on both sides of the U-shaped frame 201. The guide frame 203 abuts against the positioning ring 207. The limit plate 2011 rotates so that it can fit into the clearance groove 2016. A drive motor 205 is fixedly installed on the inner side of the U-shaped plate 208. A screw 2010 is fixedly connected to the drive motor 205. The end of the screw 2010 away from the drive motor 205 is rotatably connected to the U-shaped plate 208. A screw sleeve 209 is threaded onto the outer side of the screw 2010. A guide frame 203 is fixed to the top of the screw sleeve 209. Two inclined plates 2014 are symmetrically fixedly connected to the inner side of the U-shaped frame 201. A guide plate 2015 is fixedly connected between the two inclined plates 2014. The guide plate 2015 and the two inclined plates 2014 are fixedly connected to the carrying plate 4 and the inner plate 202. A drain outlet 2012 is provided on the U-shaped frame 201. A drain pipe communicating with the drain outlet 2012 is fixedly connected to the outer side of the U-shaped frame 201. A solenoid valve is provided on the drain pipe to facilitate the control of water discharge.

[0026] In operation, the goods are first placed inside the U-shaped frame 201, so that the goods are positioned on the corresponding support rollers 2013. Then, the two limiting plates 2011 are rotated so that they enter the two clearance grooves 2016 respectively. Then, the drive motor 205 is started, which drives the screw 2010 to rotate. Through the screw sleeve 209, the guide frame 203 slides along the guide post 206, and through the two side shafts 204, the two limiting plates 2011 slide along the two slide grooves 2017 respectively, until both slide grooves 2017 are in contact with the goods, thereby limiting the goods and preventing them from falling during the lifting process. When ice forms on the inside of the U-shaped frame 201 and the outside of the support rollers 2013, the entire device is placed in a normal temperature environment, so that the ice melts into water and is discharged from the drain outlet 2012 through the guiding effect of the inclined plate 2014 and the guide plate 2015.

[0027] Specifically, by Figure 5As shown, the support mechanism 3 includes a lifting plate 301 located below the base 1. A lower hydraulic rod 306 is fixedly installed between the lifting plate 301 and the base 1. Multiple support plates 302 are fixedly connected at equal angles to the bottom of the lifting plate 301. Multiple anti-slip particles 303 are provided on the bottom of each support plate 302. Support columns 305 are fixedly connected to the bottom of the base 1 near the four corners. A caster wheel 304 is installed at the bottom end of each support column 305. The lifting plate 301 is movably sleeved on the outside of each support column 305.

[0028] In use, the entire device is first moved by the casters 304. When the device moves to the designated position, the lower hydraulic rod 306 is activated, which drives the lifting plate 301 to slide down along the support columns 305 and drives the support plates 302 to descend, so that the anti-slip particles 303 are in close contact with the ground, preventing the entire device from moving and ensuring the stability of the device.
