Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-collision devices for cold chain transportation, and in particular to an anti-collision device for cold chain transportation. Background Technology
[0002] Cold chain transportation is mainly used for transporting fresh vegetables, medicines, vaccines, and other items. During transportation, it is necessary to prevent the items from being damaged by collisions, so they need to be protected.
[0003] As disclosed in the prior art Chinese Patent Publication No. "CN222538728U", a cold chain transportation anti-collision device includes a carriage. An anti-collision mechanism is installed inside the carriage. The anti-collision mechanism includes an installation groove, a fixed frame, a winding reel, a motor, a pull rope, and a tightening net. Installation grooves are provided at the four corners of one side of the carriage. A fixed frame is fixedly installed inside the installation groove. A winding reel is movably installed inside the fixed frame via a rotating shaft. A motor is fixedly installed at the lower end of the fixed frame inside the installation groove. The output shaft of the motor is connected to the winding reel via a coupling. A pull rope is wound around the outer surface of the winding reel.
[0004] Most existing cold chain transport anti-collision devices rely on motor-driven winding reels to tighten the pull ropes for fixation. However, after tightening, there is a lack of fixation, requiring the motor to run continuously during transport to prevent the shaft end from reversing and causing the pull ropes to loosen. This not only increases energy consumption but also affects the motor's lifespan. Furthermore, the lack of an effective guiding mechanism during winding results in uneven distribution of the pull ropes on the winding reel, which can easily lead to local accumulation or even collapse due to gravity, ultimately potentially causing fixation failure. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a cold chain transportation anti-collision device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a cold chain transportation anti-collision device, including a transport box and a tightening net installed inside the transport box. The transport box is equipped with four winding components and four drive components for driving the winding components to rotate. The four winding components are used to pull the four corners of the tightening net.
[0008] The winding assembly includes a cable and a reel. A guide component for guiding the cable is provided on one side of the winding assembly, and a one-way component is provided on another side of the winding assembly.
[0009] Furthermore, the drive assembly includes a motor, a bracket is provided inside the transport box, the motor is fixedly connected to one side of the bracket, a round shaft is fixedly connected to the shaft end of the motor, and the other end of the round shaft is rotatably connected to the bracket.
[0010] Furthermore, the reel is fixedly connected to the circumference of the circular shaft, the cable is wound inside the reel, and one end of the cable is fixedly connected to the reel. The free ends of the four cables pull the four corners of the tightening net.
[0011] Furthermore, the guide assembly includes a barrel-shaped cam fixedly connected to the round shaft, an L-shaped rod slidably connected in the groove of the barrel-shaped cam, a slider fixedly connected to the other end of the L-shaped rod, a slot being opened on the end face of the slider, and the cable passing through the slot.
[0012] Furthermore, the guide assembly also includes a guide block fixedly connected to the bracket, a groove is provided on the end face of the guide block, the L-shaped rod passes through the guide block, and the slider is slidably connected to the groove.
[0013] Furthermore, the unidirectional component includes a plate fixedly connected to the bracket and a chuck fixedly connected to the round shaft. A ratchet is fixedly connected to one side of the plate, and a pawl is rotatably connected to the circumference of the chuck. A spring is fixedly connected between the pawl and the chuck, and the pawl cooperates with the ratchet.
[0014] The present invention provides a cold chain transportation anti-collision device with the following advantages: The present invention guides the cable through a guide component, so that the cable is evenly distributed in the reel during the winding process, reducing the probability of the cable piling up in the same position. The reel is fixed by a one-way component and can rotate normally when slowly pulled. When the goods are about to collapse, a large force is generated, which causes the pawl to be thrown out due to centrifugal force and engage with the ratchet, restraining the goods and increasing the safety of the transportation process.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4 A cold chain transportation anti-collision device includes a transport box 1 and a tightening net 12 disposed inside the transport box 1. The transport box 1 is provided with four winding components 2 and four drive components 3 for driving the winding components 2 to rotate. The four winding components 2 are used to pull the four corners of the tightening net 12.
[0022] The winding assembly 2 includes a cable 21 and a winding reel 22. A guide assembly 4 for guiding the cable 21 is provided on one side of the winding assembly 2, and a one-way assembly 5 is provided on one side of the winding assembly 2.
[0023] It should be noted that the drive assembly 3 includes a motor 31, and a bracket 11 is provided inside the transport box 1. The motor 31 is fixedly connected to one side of the bracket 11, and a round shaft 32 is fixedly connected to the shaft end of the motor 31. The other end of the round shaft 32 is rotatably connected to the bracket 11, and the motor 31 drives the round shaft 32 to rotate. Of course, the motor 31 can be set as a servo motor, whose shaft end can rotate freely after power is cut off, so as to facilitate the stretching of the cable 21 during manual operation.
[0024] In this embodiment, the reel 22 is rotatably connected to the circumference of the circular shaft 32. The cable 21 is wound inside the reel 22, and one end of the cable 21 is fixedly connected to the reel 22. The free ends of the four cables 21 pull the four corners of the tightening net 12. The rotation of the circular shaft 32 causes the reel 22 to rotate, thereby winding up the cable 21 and moving the tightening net 12.
[0025] Furthermore, the guide assembly 4 includes a barrel-shaped cam 41 fixedly connected to the round shaft 32. An L-shaped rod 42 is slidably connected in the groove of the barrel-shaped cam 41. A slider 43 is fixedly connected to the other end of the L-shaped rod 42. A slot 44 is opened on the end face of the slider 43. The cable 21 passes through the slot 44 and rotates the barrel-shaped cam 41 through the round shaft 32. The rotation of the barrel-shaped cam 41 causes the L-shaped rod 42 to slide in the slot 44, thereby moving the slider 43, so that the cable 21 is evenly distributed on the winding reel 22 when winding.
[0026] The guide assembly 4 further includes a guide block 45 fixedly connected to the bracket 11. A groove 46 is provided on the end face of the guide block 45. The L-shaped rod 42 passes through the guide block 45. The slider 43 is slidably connected to the groove 46 and is guided by the groove 46.
[0027] Based on the above embodiments, the one-way component 5 includes a plate 51 fixedly connected to the bracket 11 and a chuck 52 fixedly connected to the round shaft 32. A ratchet 53 is fixedly connected to one side of the plate 51, and a pawl 54 is rotatably connected to the circumference of the chuck 52. A spring 55 is fixedly connected between the pawl 54 and the chuck 52. The pawl 54 cooperates with the ratchet 53. Under normal circumstances, the pawl 54 will disengage from the ratchet 53 due to the tension of the spring 55. The cable 21 will not jam, so slowly pulling the cable 21 will rotate the reel 22, thus pulling the cable 21 out of the reel 22. Slow pulling will not throw out the pawl 54, so it can be pulled normally. When the cargo is about to collapse, it will tilt, generating force on the tightening net and pulling the cable 21 outwards quickly. The reel 22 rotates at high speed, and the pawl 54 will be thrown out due to centrifugal force, thus engaging the ratchet 53 with the pawl 54, thereby securing the cable 21 and preventing the cargo from collapsing. (Reference) Figure 4 When the motor 31 rotates the round shaft 32 and the chuck 52, the ratchet 53 and pawl 54 will not get stuck and can rotate normally.
[0028] Operating procedure: During operation, the cable 21 is pulled out smoothly, and the goods are stacked into the transport box 1. Then, the four cables 21 are connected to the tightening net, and the motor 31 is started to retract the cables 21. After securing the goods, the motor 31 is turned off and the transport box 1 is closed to begin transportation. Upon arrival at the destination, the cables 21 and the tightening net are separated to remove the goods. After the goods are removed, the motor 31 retracts the cables 21 into the reel 22.
[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
