Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for cold chain logistics warehousing, in particular to a cold chain logistics warehouse loading and unloading device. Background Art

[0002] Cold chain logistics generally refers to a systematic process that ensures that refrigerated and frozen foods are kept at a specified low temperature throughout production, storage, transportation, sales, and consumption to ensure food quality and reduce food loss. This system is primarily used for quick-frozen foods, poultry, meat, aquatic products, as well as packaged prepared foods, ice cream and dairy products, chocolate, and fast food ingredients.

[0003] Cold storage is an important part of cold chain logistics. In the process of cold chain logistics, the transport vehicles transporting goods generally carry out loading and unloading in the cold storage or at the door of the cold storage. In the hot summer, the goods often melt, causing water to flow on the loading and unloading platform. Over time, the platform will cause ice to form, which will cause the vehicles transporting goods to slip, affecting loading and unloading. In particular, some manual forklifts have a heavy weight after loading, and if they slip, there is not only a risk of scattered goods, but also certain safety risks for operators. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a cold chain logistics warehouse loading and unloading device to solve the problem that the loading and unloading platform is prone to ice and slipping during the current cold chain process, which leads to safety risks.

[0005] The technical solution adopted by the present utility model is: a cold chain logistics warehouse loading and unloading device, including a loading and unloading truck and a loading and unloading platform located on the inner side of the cold storage door, the loading and unloading platform is equipped with a guide platform for the movement of the loading and unloading truck, the guide platform is rotatably connected to the loading and unloading platform, and a first driving mechanism for driving the guide platform to rotate is further provided between the guide platform and the loading and unloading platform, a slide is further provided on the guide platform, a strap for being overlapped on a transport vehicle is provided in the slide, a second driving mechanism is provided between the strap and the guide platform, and an electric heating tape for heating the guide platform is installed on the guide platform.

[0006] The above structure has the following beneficial effects:

[0007] 1. The guide platform rotatably connected to the loading and unloading platform and the slats that telescopically move on the guide platform can be connected to the transport vehicle, so that the loading and unloading truck can be moved to the interior of the transport vehicle for loading and unloading, which greatly improves the efficiency of loading and unloading, thereby reducing the melting of goods or cold storage materials and the chance of water flowing onto the guide platform, thereby avoiding the risk of slipping caused by ice on the guide platform and improving the safety performance of the entire equipment.

[0008] 2. The electric tracing heat band installed on the guiding platform can heat the guiding platform before the guiding platform is used, melting the ice layer on the guiding platform, thus avoiding the ice layer from causing the loading and unloading truck to slip. It can also heat the guiding platform after the guiding platform is used, evaporating the water flowing onto the guiding platform, avoiding the accumulation of water and freezing, and effectively avoiding the dangerous situation where the loading and unloading truck slips due to the ice layer.

[0009] Preferably, a third driving mechanism is further provided on the guiding platform, and a connecting member for connecting with the third driving mechanism is provided on the loading and unloading truck.

[0010] The cooperation between the third driving mechanism and the connecting member can assist the loading and unloading truck entering the guiding platform. On the one hand, it can avoid the situation of the loading and unloading truck slipping. On the other hand, it can also make it easier for the loading and unloading truck to enter the transport vehicle. At the same time, when the loading and unloading truck uses a manual forklift, since the vehicle is heavier after loading, it is difficult to control when passing through the inclined guiding platform and has a certain risk. Driving the loading and unloading truck through the third driving mechanism can also make the loading and unloading truck move more stably on the inclined guiding platform, avoiding the risk of goods falling or the vehicle slipping.

[0011] Preferably, the third driving mechanism includes a third driving component, a driving sprocket wheel connected to the third driving member, and a driving chain connected to the driving sprocket wheel. The connecting member on the loading and unloading truck is a cylindrical boss, and a plurality of grooves for clamping the connecting member are uniformly arranged on the driving chain.

[0012] The third driving component drives the driving sprocket wheel to rotate, thereby driving the driving chain to rotate around the driving sprocket wheel, and then driving the connecting member connected to the groove on the driving chain to move together, achieving the effect of driving the loading and unloading truck to move along the guiding platform through the third driving mechanism. At the same time, it also enables the smooth connection or separation between the loading and unloading truck and the driving chain.

[0013] Preferably, the third driving component includes a third driving member and a grooved pulley. A dial plate cooperating with the grooved pulley is provided at the output end of the third driving member, and the central axis of the grooved pulley is connected to the driving sprocket wheel.

[0014] The third driving component drives the dial plate to move through the third driving member, thereby periodically拨动 the grooved pulley to move, causing the driving sprocket wheel to intermittently drive the driving chain to move, so that the connecting member on the loading and unloading truck can be more safely connected to the groove on the driving chain.

[0015] Preferably, a heat preservation cover is further provided on the outer side of the cold storage warehouse door. The heat preservation cover is flexible, and a plurality of "冂"-shaped support skeletons are provided on the heat preservation cover.

[0016] The thermal insulation cover is connected to the outer wall of the transport vehicle when the transport vehicle is loading and unloading. It can block the sunlight and reduce the heat outflow from the cold storage door and the transport vehicle, thereby improving the thermal insulation effect during loading and unloading, thereby preventing the goods from melting and reducing the icing of the guide platform.

[0017] Preferably, a guide rail is further provided on the outer side of the cold storage door, two of the guide rails are symmetrically arranged along the center line of the cold storage door, and a plurality of the support frames are connected to the guide rails.

[0018] The guide rail can guide the movement of the supporting frame to facilitate the expansion or folding of the thermal insulation cover.

[0019] Preferably, the end of the guide rail away from the cold storage door is arc-shaped, and the distance between the end of the guide rail away from the cold storage door is smaller than the distance between the end of the guide rail close to the cold storage door.

[0020] Through this arrangement, the insulation cover is retracted inward at one end of the cold storage door in the yard, so as to be connected to the outer wall of the vehicle, reducing the distance between the vehicle and the cold storage door, and further improving the insulation effect.

[0021] Preferably, the top of the supporting frame is scissor-shaped.

[0022] The scissor-shaped support frame at the top can reduce the spacing on both sides of the support frame when the spacing at the top is reduced, avoiding the situation where the width of the top insulation cover is different from that of the bottom insulation cover, ensuring that the insulation cover can completely wrap the side walls and top walls of the transport vehicle, thereby improving the insulation effect.

[0023] Preferably, a magnetic part is provided at one end of the heat preservation cover away from the cold storage door.

[0024] The magnetic parts can be adsorbed on the outer wall of the transport vehicle through magnetic force, further reducing the gap between the transport vehicle and the cold storage door, thereby improving the insulation effect.

[0025] Preferably, the magnetic member is an electromagnet.

[0026] Setting the magnetic part as an electromagnet can conveniently control the magnetic part. When the magnetic part needs to be adsorbed on the side wall of the transport vehicle, the electromagnet is energized. When loading and unloading is completed, the electromagnet is deenergized, and the protective cover can be easily separated from the transport vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] According to the instruction manual Figure 1-6As shown, the utility model provides a cold chain logistics warehouse loading and unloading device, including a loading and unloading platform 20 located on the inner side of the cold storage door 10, a guide platform 30 for a loading and unloading vehicle to move is installed on the loading and unloading platform 20, and the end of the guide platform 30 away from the cold storage door 10 is rotatably connected to the loading and unloading platform 20, and a first driving mechanism 31 for driving the guide platform 30 to rotate is further connected between the guide platform 30 and the loading and unloading platform 20. In this embodiment, the loading and unloading vehicle is a manual forklift, and the first driving mechanism 31 adopts a hydraulic cylinder, wherein the bottom of the first driving mechanism 31 is rotatably connected to the loading and unloading platform On the unloading platform 20, the top of the first driving mechanism 31 is rotatably connected to the bottom of the guide platform 30; a slide is also provided at the front end of the guide platform 30, that is, the end of the guide platform 30 close to the cold storage door 10, and a strap 32 is connected inside the slide. A second driving mechanism for driving the strap 32 to perform telescopic movement along the slide is also installed between the strap 32 and the slide. In this embodiment, the slide is arc-shaped, and the upper surface of the strap 32 is also an arc-shaped that matches the slide, and the second driving mechanism is also a hydraulic cylinder, which can drive the strap 32 to extend and retract along the slide so that it can be overlapped on the transport vehicle.

[0040] An electric heating tape is evenly coiled inside the guide platform 30. The electric heating tape can heat the upper surface of the guide platform 30 to melt the ice on the upper surface of the guide platform 30 or evaporate the water on the guide platform 30 to prevent the water from condensing into an ice layer and affecting subsequent loading and unloading work.

[0041] A third driving mechanism 40 is also installed on the guide platform 30 for driving the loading and unloading vehicle to move. The third driving mechanism 40 has two groups and is symmetrically installed on both sides of the guide platform 30. A connecting piece 61 for connecting to the third driving mechanism 40 is also provided on the loading and unloading vehicle. In this embodiment, the connecting piece 61 is a circular cylinder slidably connected to the loading and unloading vehicle, and a hole for accommodating the connecting piece 61 is opened on the loading and unloading vehicle. When the loading and unloading vehicle does not need to be driven by the third driving mechanism 40 to move, the connecting piece can be 61 is received in the hole, and when the loading and unloading trolley needs to be driven to move by the third driving mechanism 40, the connecting member 61 can be pulled out of the hole and fixed to the side of the loading and unloading trolley so as to be connected to the third driving mechanism 40, thereby driving the loading and unloading trolley to move. In this embodiment, the connecting member 61 is only installed at the rear end of the loading and unloading trolley. If the goods to be loaded and unloaded are heavy, or the loading and unloading trolley is large, the connecting member 61 can also be installed at the front end of the loading and unloading trolley, so that the loading and unloading trolley can pass through the guide platform 30 more stably.

[0042] In this embodiment, the third driving mechanism 40 includes a third driving assembly 44, a driving sprocket 41 connected to the third driving assembly 44, a driven sprocket 42 and a driving chain 43, wherein the driving sprocket 41 and the driven sprocket 42 are respectively rotatably connected to the guide platform 30 through a mounting seat, and the driving chain 43 is wound around the outside of the driving sprocket 41 and the driven sprocket 42 and connects the driving sprocket 41 and the driven sprocket 42. A plurality of semicircular grooves 431 for locking the connecting member 61 are evenly opened on the driving chain 43, so that the connecting member 61 1 can move along with the drive chain 43. At the same time, a limit plate 33 is fixedly installed above the drive chain 43. The limit plate 33 is supported by a self-lubricating material such as nylon. The limit plate 33 can limit the connecting member 61 in the groove 431 to ensure that the connecting member 61 can move along with the drive chain 43. The use of the limit plate 33 made of nylon can reduce the friction between the connecting member 61 and the limit plate 33, thereby increasing the service life of the limit plate 33 and reducing the obstruction of the limit plate 33 on the connecting member 61.

[0043] In this embodiment, the third drive assembly 44 includes a third drive member 441, a groove wheel 442, and a dial 443, wherein the third drive member 441 is a motor, and the output shaft of the three drive members is connected to the dial 443, and the groove wheel 442 is connected to the drive sprocket 41 through the transmission sprocket group 444, and the dial 443 is engaged with the groove wheel 442. When the third drive member 441 drives the dial 443 to rotate, the groove wheel 442 is periodically driven by the dial 443 to move, thereby causing the drive sprocket 41 to rotate intermittently; through such a setting, the drive chain 43 moves intermittently, which can facilitate the connection between the connecting member 61 and the groove 431 on the drive chain 43.

[0044] In this embodiment, a cover plate 21 is further installed between the guide platform 30 and the loading and unloading platform 20 for covering the gap between the guide plate and the loading and unloading platform 20. The cover plate 21 is rotatably connected to the loading and unloading platform 20, and a torsion spring is provided between the cover plate 21 and the loading and unloading platform 20 so that the cover plate 21 can continuously abut against the upper surface of the guide platform 30, thereby ensuring that the gap can be stably covered regardless of the angle of the guide platform 30.

[0045] Its working principle is as follows. When goods need to be loaded and unloaded in a cold chain warehouse, the transport vehicle is parked at the cold storage warehouse door 10, and the cold storage warehouse door 10 is opened. Then, the first driving mechanism 31 is driven to rotate the guiding platform 30, and the second driving mechanism is used to drive the boarding plate 32 to extend and overlap on the transport vehicle, so that the subsequent loading and unloading vehicle can smoothly enter the transport vehicle. At this time, if there is ice or water accumulation on the guiding platform 30, the electric tracing heating belt is turned on to heat the guiding platform 30 to melt the ice or evaporate the water, preventing the loading and unloading vehicle from slipping on the guiding platform 30. At the same time, the connecting piece 61 on the loading and unloading vehicle is pulled out and pushed onto the guiding platform 30, so that the connecting piece 61 is connected to the groove 431 on the driving chain 43, and under the driving of the third driving component 44, it moves upward or downward to realize the assistance to the loading and unloading vehicle, further avoiding the situation that the loading and unloading vehicle slips when facing or leaving the transport vehicle.

[0046] Embodiment 2

[0047] According to the attached drawings of the specification Figure 7-9 As shown, the difference between this embodiment and Embodiment 1 is that a heat preservation cover 51 is further installed outside the cold storage warehouse door 10. The heat preservation cover 51 is made of flexible material, and several "冂"-shaped support skeletons 52 are installed on the inner side of the heat preservation cover 51 to support the heat preservation cover 51. At the same time, two guide rails 53 are installed on the bottom surface outside the cold storage warehouse door 10. The support skeletons 52 are connected to the guide rails 53 and can move along the guide rails 53.

[0048] In this embodiment, the end of the guide rail 53 far from the cold storage warehouse door 10 is arc-shaped, and the distance between the two ends of the guide rail 53 far from the cold storage warehouse door 10 is smaller than the distance between the ends close to the cold storage warehouse door 10, so that the left and right ends of the heat preservation cover 51 are getting closer and closer during the movement along the guide rail 53, and then can overlap on the outside of the transport vehicle. At the same time, the top of the support skeleton 52 is scissor-shaped. Such a setting enables the top of the support skeleton 52 to expand and contract while the two sides of the support skeleton 52 change the distance following the guide rail 53, so that the heat preservation cover 51 can be more closely attached to the outside of the transport vehicle.

[0049] A magnetic part 54 is further installed at the end of the heat preservation cover 51. The magnetic part 54 can be magnetically adsorbed on the outer side wall of the transport vehicle, further reducing the gap between the transport vehicle and the cold storage warehouse door 10, thereby improving the heat preservation effect. In this embodiment, the magnetic part 54 uses an electromagnet, which can conveniently control the magnetic part 54. When it is necessary for the magnetic part 54 to adsorb on the side wall of the transport vehicle, the electromagnet is powered on, and when the loading and unloading are completed, the electromagnet is powered off, and the protective cover can be conveniently separated from the transport vehicle.

[0050] Its working principle is that when the transport vehicle is parked at the cold storage door 10, the support frame 52 is pulled to drive the thermal insulation cover 51 to move, and the end cover of the transport vehicle is set inside the thermal insulation cover 51. Then, by energizing the electromagnet, the end of the thermal insulation cover 51 is adsorbed on the outer surface of the transport vehicle to fix the thermal insulation cover 51, thereby reducing the heat exchange between the inside of the cold storage and the outside world, effectively preventing the outside hot air from entering and affecting the goods, and also preventing the goods from melting or the water vapor in the hot air from condensing and causing a layer of ice to condense on the guide platform 30.
