Description

Technical Field

[0001] This utility model relates to the field of cold storage shuttle vehicle technology, specifically a cold storage shuttle vehicle with anti-slip function for drive wheels. Background Technology

[0002] In the fields of cold chain logistics, food processing, and pharmaceutical storage, cold storage is the core facility for low-temperature storage. The stable operation of the automated handling equipment inside the cold storage (such as cold storage shuttles) directly determines the storage efficiency and cargo safety. Cold storage shuttles mainly move goods back and forth along fixed tracks. However, when the shuttles operate inside the cold storage, they face significant environmental characteristics such as low temperature (usually -10℃ to -60℃), high humidity (relative humidity 50%-90%), and easy frost / ice formation. This causes the friction coefficient between the shuttle's drive wheels and the track to decrease significantly. Furthermore, the frost on the track surface caused by cold air can lead to slippage, which is the core cause of drive wheel slippage. Slippage can easily cause the shuttle to deviate to one side or spin idly, affecting the efficiency of cargo docking and making it extremely inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a cold storage shuttle with anti-slip function for the drive wheels, so as to solve the problem mentioned in the background art that the shuttle in the cold storage is prone to slipping and affecting the docking of goods.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cold storage shuttle with anti-slip function for drive wheels, comprising a vehicle body, a drive shaft rotatably mounted on the outer surface of one end of the vehicle body, and both ends of the drive shaft passing through both sides of the vehicle body; a reduction drive motor fixedly mounted inside the vehicle body, and the reduction drive motor connected to the drive shaft; an electric push rod fixedly mounted inside the vehicle body; main drive wheels fixedly mounted on both ends of the drive shaft, and the outer surface of the main drive wheels is provided with anti-slip texture, and the main drive wheels are located on both sides of the vehicle body; a second gear rotatably mounted on the outer surface of one end of the drive shaft near the outer surface of the vehicle body, and a plastic rope wheel passing through the outer surface of the second gear, and the plastic rope wheel being fixed to the rotation shaft of the second gear with a nut; the plastic rope wheel being located on one side of the main drive wheel, and the outer surface of the main drive wheel being in contact with the outer surface of the plastic rope wheel; and a transmission mechanism being provided between the second gear and the drive shaft.

[0005] Preferably, the transmission mechanism includes: a first synchronous pulley, the first synchronous pulley being fixedly mounted on the outer surface of the drive shaft, a rotating shaft being rotatably mounted at one end of the vehicle body, and a first gear being fixedly mounted at both ends of the rotating shaft, the first gear meshing with a second gear, a second synchronous pulley being fixedly mounted on the outer surface of the rotating shaft, and a synchronous belt being provided between the second synchronous pulley and the first synchronous pulley.

[0006] Using the above technical solution, when the reduction drive motor drives the drive shaft to rotate, the first synchronous pulley will drive the second synchronous pulley to rotate through the synchronous belt, so that the shaft can rotate synchronously with the drive shaft. The first gear and the second gear can drive the plastic rope wheel to rotate synchronously, so that the plastic rope wheel also rotates synchronously when the vehicle moves. The plastic rope wheel can also automatically switch directions according to the direction of movement of the vehicle to facilitate linkage operation.

[0007] Preferably, a slip ring is fixedly installed inside the vehicle body, and the rotating end of the slip ring is connected to the drive shaft. The drive shaft and the slip ring are concentrically designed. An electromagnet is fixedly installed on the outer surface of the slip ring. An anti-slip rotating disk is engaged with the outer surface of the drive shaft, and the anti-slip rotating disk is slidably connected to the drive shaft. A protective cover adsorption block is fixedly installed on the outer surface of the anti-slip rotating disk near the slip ring, and the outer surface of the protective cover adsorption block is in contact with the outer surface of the electromagnet. A spring is provided between the electromagnet and the anti-slip rotating disk, and the spring is located inside the protective cover adsorption block.

[0008] By adopting the above technical solution, the setting of the slip ring can ensure that the rotation of the drive shaft will not affect the energization and use of the electromagnet, and the protective cover adsorption block can limit the spring to prevent it from deviating during use and affecting its use. At the same time, the electromagnet can adsorb and limit the anti-slip rotating disk by adsorbing the protective cover adsorption block, which can flexibly adjust the working position of the anti-slip rotating disk, reduce the wear of the anti-slip rotating disk and the track, and improve the service life.

[0009] Preferably, the outer surface of the anti-slip rotating disk is uniformly provided with columnar bodies, and the columnar bodies of the anti-slip rotating disk are inserted into the main drive wheel, and the outer surface of the columnar bodies of the anti-slip rotating disk is in contact with the outer surface of the track.

[0010] By adopting the above technical solution, the cylindrical body of the anti-slip rotating disc can be inserted into the side surface of the main drive wheel, allowing the cylindrical body of the anti-slip rotating disc to contact the outer surface of the track, and allowing the anti-slip rotating disc to embed into the frozen part of the track surface, thereby further improving the anti-slip performance of the main drive wheel.

[0011] Preferably, the anti-slip rotating disc passes through the outer surface of the vehicle body, and the vehicle body does not contact the outer surface of the anti-slip rotating disc; the anti-slip rotating disc is housed inside the vehicle body.

[0012] By adopting the above technical solution, the anti-slip rotating disc can be stored inside the vehicle body when not in use, so that the anti-slip rotating disc will not come into contact with the track when the vehicle body moves, thus affecting the use of the shuttle.

[0013] Preferably, a rotating rod is rotatably mounted inside the vehicle body near the electric push rod, and a rod is provided on the outer surface of the rotating rod. The two ends of the rotating rod pass through both sides of the vehicle body. A rocker arm is fixedly mounted at one end of the rotating rod outside the vehicle body, and an ice-breaking wheel is rotatably mounted at one end of the rocker arm. The outer surface of the ice-breaking wheel is evenly provided with strip-shaped protrusions. A tension spring is hung between the rotating rod and the vehicle body. The ice-breaking wheel is located above the track, and the side surface of the ice-breaking wheel does not fit against the outer surface of the track.

[0014] Using the above technical solution, the rotating rod can be rotated by pulling the tension spring, which can drive the rocker arm to swing and allow the ice-breaking wheel to closely adhere to the outer surface of the track. The strip-shaped protrusions on the outer surface of the ice-breaking wheel can crush and break the ice layer on the track surface. When the shuttle moves back and forth, it can break the ice layer and reduce the chance of slippage when the main drive wheel rotates.

[0015] Preferably, a limiting roller push rod is fixedly installed at the output end of the electric push rod, and the limiting roller push rod is slidably connected to the vehicle body. The vehicle body is engaged with the limiting roller push rod, the outer surface of the limiting roller push rod is engaged with the outer surface of the rotating rod, and the outer surface of the rotating rod is in contact with the outer surface of the limiting roller push rod.

[0016] By adopting the above technical solution, the extension of the electric actuator can drive the limit roller actuator to move, allowing the limit roller actuator to push the rotating rod to rotate and lift the rocker arm, so that the icebreaker wheel can be separated from the outer surface of the track, greatly reducing the wear of the track and the icebreaker wheel, and preventing the icebreaker wheel from working continuously.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the cold storage shuttle vehicle with anti-slip function for the drive wheels: 1. When the geared drive motor starts and drives the drive shaft to rotate, it will drive the first synchronous pulley and the main drive wheel to rotate together. The first synchronous pulley can drive the second synchronous pulley to rotate synchronously through the synchronous belt. This allows the shaft to drive the first gear to rotate, and the second gear meshing with the first gear to rotate synchronously. This allows the plastic rope wheel to rotate synchronously. As the plastic rope wheel rotates, the plastic rope is thrown between the main drive wheel and the track. When the vehicle moves, it can increase the friction by crushing the plastic rope wheel, thereby reducing the chance of the shuttle slipping and ensuring that the efficiency of the shuttle in transporting goods is not affected. 2. During the initial use each day, the limit roller push rod can be retracted by retracting the electric push rod, allowing the rotating rod in contact with the limit roller push rod to rotate under the tension of the spring. This allows the rocker arm to rotate and lower the ice-breaking wheel, enabling the outer surface of the ice-breaking wheel to contact the outer surface of the track. The strip-shaped protrusions on the outer surface of the ice-breaking wheel allow the ice layer on the track surface to be broken by the ice-breaking wheel when the vehicle moves. The limit roller push rod can be pushed by the electric push rod to reset the rotating rod, greatly reducing the slippage caused by the smooth ice surface of the track when the shuttle moves on the track. The ice-breaking wheel can also be retracted when not in use. 3. If slippage still occurs during shuttle operation, the electromagnet can be de-energized to allow the spring to push out the anti-slip rotating disc, enabling the cylinder of the anti-slip rotating disc to insert into the main drive wheel. This allows the main drive wheel to engage with the anti-slip rotating disc, and the cylinder of the anti-slip rotating disc to contact the outer surface of the track, further reducing the chance of the shuttle slippage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a cold storage shuttle with anti-slip function for drive wheels, including a vehicle body 1. A drive shaft 2 is rotatably mounted on the outer surface of one end of the vehicle body 1, and both ends of the drive shaft 2 pass through both sides of the vehicle body 1. A reduction drive motor 3 is fixedly installed inside the vehicle body 1 and is connected to the drive shaft 2. An electric push rod 17 is fixedly installed inside the vehicle body 1. Main drive wheels 4 are fixedly mounted on both ends of the drive shaft 2, and the outer surface of the main drive wheels 4 is provided with anti-slip texture. The main drive wheels 4 are located on both sides of the vehicle body 1. A second gear 10 is rotatably mounted on the outer surface of one end of the drive shaft 2 near the outer surface of the vehicle body 1, and a plastic rope wheel is provided through the outer surface of the second gear 10. 11. The plastic rope wheel 11 is fixed to the rotating shaft of the second gear 10 with a nut. The plastic rope wheel 11 is located on one side of the main drive wheel 4, and the outer surface of the main drive wheel 4 is in contact with the outer surface of the plastic rope wheel 11. A transmission mechanism is provided between the second gear 10 and the drive shaft 2. The transmission mechanism includes: a first synchronous pulley 5, which is fixedly installed on the outer surface of the drive shaft 2. A rotating shaft 7 is rotatably installed at one end of the vehicle body 1, and a first gear 9 is fixedly installed at both ends of the rotating shaft 7. The first gear 9 meshes with the second gear 10. A second synchronous pulley 8 is fixedly installed on the outer surface of the rotating shaft 7, and a synchronous belt 6 is provided between the second synchronous pulley 8 and the first synchronous pulley 5.

[0022] Firstly, during operation, the reduction drive motor 3 will drive the drive shaft 2 to rotate, causing the first synchronous pulley 5 to drive the second synchronous pulley 8 to rotate via the synchronous belt 6. This allows the rotating shaft 7 to drive the first gear 9 to rotate, and the second gear 10, which meshes with the first gear 9, to rotate. The second gear 10 then drives the plastic rope wheel 11 to rotate, allowing the car body 1 to move along the track. The plastic rope wheel 11 can then be inserted between the main drive wheel 4 and the track, increasing the friction between the main drive wheel 4 and the track. This prevents slippage when the shuttle moves forward and backward, greatly improving the stability of the shuttle within the cold storage and ensuring its cargo transportation efficiency.

[0023] A slip ring 12 is fixedly installed inside the vehicle body 1, and the rotating end of the slip ring 12 is connected to the drive shaft 2. The drive shaft 2 and the slip ring 12 are concentrically designed. An electromagnet 13 is fixedly installed on the outer surface of the slip ring 12. An anti-slip rotating disk 14 is engaged with the outer surface of the drive shaft 2, and the anti-slip rotating disk 14 is slidably connected to the drive shaft 2. A protective cover adsorption block 15 is fixedly installed on the outer surface of the end of the anti-slip rotating disk 14 near the slip ring 12, and the outer surface of the protective cover adsorption block 15 is flush with the outer surface of the electromagnet 13. A spring 16 is provided between the electromagnet 13 and the anti-slip rotating disk 14. The spring 16 is located inside the protective cover adsorption block 15. The outer surface of the anti-slip rotating disk 14 is uniformly provided with columnar bodies, and the columnar bodies of the anti-slip rotating disk 14 are inserted into the main drive wheel 4. The outer surface of the columnar bodies of the anti-slip rotating disk 14 is in contact with the outer surface of the track. The anti-slip rotating disk 14 passes through the outer surface of the vehicle body 1, and the vehicle body 1 does not contact the outer surface of the anti-slip rotating disk 14. The anti-slip rotating disk 14 is stored inside the vehicle body 1.

[0024] Secondly, when the shuttle still slips while moving on the track, the electromagnet 13 can be de-energized, allowing it to detach from the protective cover adsorption block 15. The spring 16 then pushes out the anti-slip rotating disk 14. Through the engagement of the anti-slip rotating disk 14 with the drive shaft 2, the anti-slip rotating disk 14 can be accurately inserted into the main drive wheel 4, allowing the cylinder of the anti-slip rotating disk 14 to contact the outer surface of the track when the main drive wheel 4 rotates, further reducing the chance of the shuttle slipping. Furthermore, the use of the slip ring 12 allows the electromagnet 13 to adsorb the protective cover adsorption block 15 when the anti-slip rotating disk 14 is not in use, enabling the anti-slip rotating disk 14 to retract into the inside of the vehicle body 1. This further enhances the anti-slip performance of the shuttle and allows for flexible switching between operating states, greatly improving its practicality.

[0025] A rotating rod 19 is rotatably mounted inside the vehicle body 1 near the electric push rod 17, and a rod is provided on the outer surface of the rotating rod 19. The two ends of the rotating rod 19 pass through both sides of the vehicle body 1. A rocker arm 20 is fixedly mounted on one end of the rotating rod 19 outside the vehicle body 1, and an ice-breaking wheel 22 is rotatably mounted on one end of the rocker arm 20. The outer surface of the ice-breaking wheel 22 is evenly provided with strip-shaped protrusions. A tension spring 21 is hung between the rotating rod 19 and the vehicle body 1. The ice-breaking wheel 22 is located above the track, and the side surface of the ice-breaking wheel 22 does not fit with the outer surface of the track. A limiting roller push rod 18 is fixedly mounted on the output end of the electric push rod 17, and the limiting roller push rod 18 is slidably connected to the vehicle body 1. The vehicle body 1 is engaged with the limiting roller push rod 18, and the outer surface of the limiting roller push rod 18 is engaged with the outer surface of the rotating rod 19. The outer surface of the rotating rod 19 is also in contact with the outer surface of the limiting roller push rod 18.

[0026] When the shuttle is used for the first time each day, the limit roller push rod 18 can be retracted by the retraction of the electric push rod 17. In conjunction with the pull of the tension spring 21 on the rotating rod 19, the rotating rod 19 can rotate and the rocker arm 20 can fall, allowing the ice-breaking wheel 22 to contact the track. As the vehicle body 1 moves, the ice-breaking wheel 22 can move while squeezing and breaking the ice layer on the track, making the ice layer on the track surface rough and removing some of the ice layer, thereby further reducing the chance of the main drive wheel 4 slipping. After the track is crushed, the electric push rod 17 can push out the limit roller push rod 18, allowing the rotating rod 19 and the ice-breaking wheel 22 to reset, and allowing the ice-breaking wheel 22 to move away from the track, greatly improving the practicality of the shuttle.

[0027] Working principle: When the shuttle is in use daily, the retraction of the electric push rod 17 resets the limit roller push rod 18, allowing the tension spring 21 to pull the rotating rod 19, which in turn rotates the rocker arm 20. This allows the ice-breaking wheel 22 to descend and contact the track. Then, the reduction drive motor 3 drives the drive shaft 2 to rotate, which in turn drives the main drive wheel 4. The first synchronous pulley 5, via the synchronous belt 6, drives the rotating shaft 7 and the second synchronous pulley 8 to rotate simultaneously. This allows the first gear 9 to drive the second gear 10 and the plastic rope wheel 11 to rotate, allowing the plastic rope... The rotating wheel 11 can be thrown between the main drive wheel 4 and the track as it rotates, allowing the shuttle to crush and break the ice on the track surface while moving, and increasing the friction of the main drive wheel 4. When the main drive wheel 4 still slips, the electromagnet 13 can be de-energized, allowing the spring 16 to push out the anti-slip rotating disc 14, so that the anti-slip rotating disc 14 can be accurately inserted into the surface of the main drive wheel 4, which can further increase the friction between the main drive wheel 4 and the track, allowing the shuttle to move stably on the track in the cold storage and transport goods.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
