[0002] The heavy-loaded four-way shuttle is a device used in warehousing and logistics systems. It is mainly used to move goods horizontally between shelves. It can carry heavy goods and has the flexibility of horizontal movement. It can be used to efficiently transport goods and complete warehousing operations. When the heavy-loaded four-way shuttle is used in a low-temperature environment, the performance of the battery will be reduced, resulting in a decrease in the battery's energy storage and discharge rate, affecting the working time and operating efficiency of the four-way shuttle, so insulation measures need to be taken.

[0003] When working in a low-temperature environment, the surface of the heavy-load four-way shuttle is prone to ice. When starting or stopping, objects will easily slide off the four-way shuttle due to inertia, which may cause damage or breakage of the objects. A fencing device needs to be set up to prevent such situations from happening.

[0004] After searching, the Chinese patent with the authorization announcement number "CN220222394U" provides "a new type of four-way shuttle vehicle, which realizes multi-directional recognition of QR code marks by setting multiple QR code identifiers, and at the same time sets a moving wheel assembly and auxiliary wheels, so that it can not only run on the track, but also travel on the industrial ground that meets the requirements, thereby saving the track cost". Although the device can travel on the ground, saving the cost of using the track, but in a low temperature environment, the device is prone to water vapor freezing on the surface of the vehicle body, and objects are easy to slip on the surface of the vehicle body. When starting and stopping, the objects may slide out due to inertia, and the objects placed on the device cannot be enclosed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a heavy-load four-way shuttle vehicle for low temperature, such as Figure 1As shown, the shuttle vehicle body 1, the pallet 2 and the enclosure mechanism 3 are included. The pallet 2 is arranged above the shuttle vehicle body 1. Both ends of the pallet 2 are provided with an enclosure mechanism 3 for preventing the goods from sliding off the pallet 2 during transportation. Figure 2 and Figure 5 As shown, the enclosure mechanism 3 includes a driving assembly 31 and a rotating assembly 32. The driving assembly 31 is provided at both ends of one side of the shuttle body 1, and the rotating assembly 32 is provided at the upper end of the driving assembly 31. The driving assembly 31 includes a side seat 311, a pusher 312, a rack 313 and a rotating shaft 314. The side seat 311 is fixed on the shuttle body 1, the pusher 312 is fixed on the side seat 311, one end of the pusher 312 is provided with a rack 313, the rotating shaft 314 is rotatably connected to the support plate 2, one end of the rotating shaft 314 is fixedly connected with a gear 3141, and the gear 3141 is meshed with the rack 313. The rotating assembly 32 includes a baffle 321 and a connector 322. Two groups of connectors 322 are provided on one side of the baffle 321, and the rotating shaft 314 penetrates and is fixed on the two groups of connectors 322. The holes opened at both ends of the baffle 321 are rotatably connected with rollers 323.

[0025] The pushing member 312 may be a cylinder or a hydraulic pump.

[0026] When the baffle 321 is in a flat state, a pallet carrying goods to be transported is placed on the pallet 2, and the pallet is pushed in from the baffle 321 on one side. The setting of the roller 323 is conducive to the smooth movement of the pallet. When the pallet completely enters the pallet 2, the two sets of pushers 312 are started, so that the pushers 312 push the rack 313 set at one end to move horizontally, thereby driving the rotating shaft 314 fixed with the gear 3141 to rotate, so that the baffle 321 rotates and stands upright at both ends of the pallet 2, limiting the pallet to prevent the pallet from sliding out of the four-way shuttle due to inertia when the device is started or stopped, causing damage to the goods.

[0027] like Figure 5 As shown, a rubber layer 3231 is provided on the outer side of the roller 323 . The rubber layer 3231 coated on the outer side of the roller 323 increases the wear resistance of the roller 323 and increases the friction between the roller 323 and the tray.

[0028] like Figure 4As shown, both ends of the shuttle body 1 are fixedly connected with docking blocks 4, and the surface of the docking block 4 away from the support plate 2 is provided with an alignment groove 41 running through the upper and lower surfaces thereof, one side of the connector 322 is fixedly connected with a limiting block 3221, and the other side of the limiting block 3221 is fixedly connected with an alignment rod 3222, and the alignment rod 3222 corresponds to the alignment groove 41, and the baffle plate 321 is rotated to make the alignment rod 3222 enter the alignment groove 41, at this time, the limiting block 3221 is flush with the docking block 4, so that the baffle plate 321 is in a flat state, and when the baffle plate 321 bears the load for a long time, it may be severely deformed, so that the baffle plate 321 is no longer flat, and at this time, the alignment rod 3222 will not be able to enter the alignment groove 41, and a prompt is given to replace the baffle plate 321.

[0029] like Figure 3 As shown, resistance-enhancing belts 21 are fixedly connected to both sides of the upper end of the pallet 2, and multiple groups of protrusions are linearly arranged in the extension direction of the resistance-enhancing belt 21. The multiple groups of protrusions fixed on the resistance-enhancing belt 21 increase the friction between the pallet 2 and the tray, which is beneficial to the stable transportation of goods.

[0030] like Figure 1 and Figure 6 As shown, the shuttle body 1 is provided with insulation foam 5 around the periphery, and the insulation foam 5 covering the shuttle body 1 plays a role in insulating the shuttle body 1. A box 3121 is provided on the outer side of the pusher 312 to insulate the pusher 312.

[0031] Adopting the utility model, such as Figure 1 and Figure 2 As shown in the figure, when the baffle 321 is in a flat state, a pallet carrying goods to be transported is placed on the pallet 2, and the pallet is pushed in from the baffle 321 on one side. The setting of the roller 323 is conducive to the smooth movement of the pallet. When the pallet completely enters the pallet 2, the two sets of pushing members 312 are started, so that the pushing members 312 push the rack 313 set at one end to make it move horizontally, thereby driving the rotating shaft 314 fixed with the gear 3141 to rotate, so that the baffle 321 rotates and stands upright at both ends of the pallet 2, limiting the position of the pallet to prevent the pallet from being moved when the device is started or stopped. The plate may slide off the four-way shuttle due to inertia, causing damage to the goods. After the goods are transported to the designated location, the pusher 312 is used to rotate the baffle 321 so that the alignment rod 3222 enters the alignment slot 41. At this time, the limit block 3221 is in flush contact with the docking block 4, so that the baffle 321 is in a flat state, which is convenient for unloading the goods. After the baffle 321 has been under load for a long time, it may be severely deformed, making the baffle 321 no longer flat. At this time, the alignment rod 3222 will not be able to enter the alignment slot 41, and a prompt will be given to replace the baffle 321.

[0032] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
