Description

Technical Field

[0001] This invention relates to the field of cold chain logistics technology, specifically to a refrigeration equipment installation device for cold chain logistics engineering. Background Technology

[0002] Cold chain logistics is a core link in ensuring the quality of temperature-sensitive materials such as food, pharmaceuticals, and biological products. Its refrigeration equipment needs to operate stably under complex conditions over long periods. However, refrigeration equipment often faces multi-source vibration interference during transportation and storage, including vehicle engine vibration, road bumps, and the equipment's own mechanical movement. Vibration not only leads to fatigue damage to equipment components and reduced energy efficiency, but can also cause refrigerant leaks and excessive temperature fluctuations, directly affecting cargo safety and increasing maintenance costs. Summary of the Invention

[0003] The purpose of this invention is to provide a refrigeration equipment installation device for cold chain logistics engineering, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a refrigeration equipment installation device for cold chain logistics engineering, comprising a main body of a vehicle and a first installation component for fixing a refrigeration unit, wherein the first installation component is disposed at the front end of the interior of the main body of the vehicle; The first mounting assembly includes a base and a support. The support is connected to the top of the base by several spring shock absorbers. The refrigeration unit is fixed on the support. Fixed seats are evenly distributed around the top surface of the base. Several adjusting components are arranged along the height direction on the inner end face of each fixed seat. Each adjusting component includes a spring-loaded plug and a connecting rod. The connecting rod is mounted on the fixed seat and the spring-loaded plug is connected to the connecting rod. The side of the support has a matching socket corresponding to the position of each spring-loaded plug. A power component is provided on the fixed seat. The power component is used to synchronously push all the spring-loaded plugs on the same horizontal plane into or out of the socket to change the elastic support force of the support. The elastic plug includes a connecting plate, a fixed plate, and a movable plate. The fixed plate is fixedly disposed at the bottom of the front end face of the connecting plate, and the movable plate is slidably assembled on the front end face of the connecting plate. A miniature spring shock absorber is connected between the fixed plate and the movable plate, and the rear end face of the connecting plate is mounted on the connecting rod.

[0005] Furthermore, the first mounting assembly also includes a base, on which the base is movably mounted. The base is mounted on the main body of the carriage. Each side end face of the base is provided with several support rings. Adjustment seats are evenly distributed around the top surface of the base. A motor is installed in one end of the adjustment seat. A spool is installed on the output shaft of the motor. An elastic rope is installed on the spool. One end of the elastic rope passes through each support ring on the same side and is fixed to the other end of the adjustment seat. Rotation of the spool can wind and unwind the elastic rope, thereby adjusting the tension of the elastic rope.

[0006] Furthermore, the power assembly includes several connecting pipes and several control valves. The fixed base has several movable cavities corresponding to each connecting rod. The connecting rod slides through the movable cavity, with one end extending to the outside of the fixed base and connected to the elastic plug, and the other end connected to the seal. A return spring is connected between the connecting rod and the inner wall of the movable cavity. The ends of each movable cavity on the same horizontal plane away from the support are connected through the connecting pipes. Several control valves are provided on one of the fixed bases. One end of the control valve is connected to the corresponding connecting pipe, and the other end is connected to an external air source. High-pressure fluid can be introduced into the connecting pipe, thereby synchronously pushing all the elastic plugs on the same horizontal plane into the socket.

[0007] Furthermore, a millimeter-wave radar is deployed at the front of the main body of the vehicle to identify the road conditions ahead and send a signal to the processor, which is electrically connected to the control valve and the external air source.

[0008] Furthermore, the outer end of the socket has a guide structure that gradually decreases in size from the outside to the inside, and its outer end size is larger than the size of the elastic plug. This structure allows the elastic plug to be inserted into the socket under the guidance of the guide structure even if the socket and the elastic plug are not completely aligned.

[0009] Furthermore, it also includes a second mounting assembly for securing cargo, which is disposed within the main body of the carriage. The second mounting assembly includes a transport mechanism and a heat insulation mechanism. The transport mechanism includes a pair of sliding rods, a pair of upper sliding rods, and a drive mechanism. The top and bottom ends of the main body of the carriage are respectively provided with upper sliding grooves and lower sliding grooves corresponding to the upper and lower sliding rods. The upper and lower sliding rods are respectively embedded in the upper and lower sliding grooves. Several lower sliding seats are slidably connected between the two lower sliding rods, and several corresponding upper sliding seats are slidably connected between the two upper sliding rods. Several support members are connected between the corresponding upper and lower sliding seats. Cargo can be placed on the front side of the support members. The drive mechanism is disposed on the top of the main body of the carriage, and the upper sliding seats are selectively connected to the drive mechanism, thereby driving the upper sliding seats and their lower support members and lower sliding seats to move horizontally to push the cargo outward. The heat insulation mechanism includes several heat insulation plates, each of which is distributed on the left and right sides inside the main body of the carriage, and the heat insulation plates are rotatably mounted on the main body of the carriage.

[0010] Furthermore, the driving mechanism includes a belt drive mechanism, which is embedded in the middle of the top of the carriage body. Several iron blocks are arranged on the drive belt of the belt drive mechanism, and an electromagnet is arranged in the middle of the top of the upper slide. When the electromagnet is energized, it can be attracted to the iron blocks.

[0011] Furthermore, the support member is an elastic band, and both the upper slide and the lower slide have several corresponding mounting holes. A support rod is installed in the mounting hole, and the elastic band is sleeved on the two corresponding support rods.

[0012] Furthermore, a rotating shaft is provided at one end of the heat insulation plate, and the rotating shaft is rotatably mounted on the main body of the carriage. A torsion spring is connected between the rotating shaft and the main body of the carriage. When the torsion spring is in a free angular displacement state, the heat insulation plate and the support are parallel, and the width of the heat insulation plate is half the width of the main body of the carriage.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention forms a shock absorption mechanism with adaptively adjustable stiffness through the synergistic effect of spring shock absorbers and elastic plugs. It can absorb the low-frequency vibration of vehicle bumps and suppress the high-frequency resonance of refrigeration equipment operation. The intelligent linkage between millimeter-wave radar and processor can sense road conditions in real time and dynamically adjust the insertion state of the elastic plugs to achieve adaptive matching of shock absorption stiffness.

[0014] 2. The elastic rope tensioning system of the present invention dynamically adjusts the tension by driving a reel with a motor, balancing the inertial forces during turning, tilting, or sudden load changes, preventing equipment deviation or resonance, dispersing lateral impact energy, and improving overall bending and torsional resistance. 3. This invention achieves rapid loading and unloading of goods through a semi-automatic pushing design that combines a belt drive mechanism with an electromagnet. Workers can complete the loading and unloading without entering the compartment, shortening the loading and unloading time, reducing the intensity of manual operation, and effectively preventing workers from inhaling large amounts of cold air, thus protecting their health.

[0015] 4. In this invention, the heat insulation plate driven by the torsion spring automatically opens and closes during loading and unloading, forming a temporary partition to reduce cold air leakage. It can separate frozen goods loaded in front or temporarily unloaded in front from the rear and maintain refrigeration, thus ensuring the cold preservation effect. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, a refrigeration equipment installation device for a cold chain logistics project is characterized by comprising a main body 1 of a vehicle and a first installation component 37 for fixing a refrigeration unit 5, wherein the first installation component 37 is disposed at the front end of the interior of the main body 1 of the vehicle. The first mounting component 37 includes a base 2 and a support 3. The support 3 is connected to the top of the base 2 by a plurality of spring shock absorbers 4. The refrigeration unit 5 is fixed on the support 3. Fixed seats 6 are evenly distributed around the top surface of the base 2. A plurality of adjustment components are arranged on the inner end face of each fixed seat 6 along its height direction. The adjustment component includes a spring plug 7 and a connecting rod 8. The connecting rod 8 is assembled on the fixed seat 6 and the spring plug 7 is connected to the connecting rod 8. The side of the support 3 is provided with a matching socket 9 corresponding to the position of each spring plug 7. A power component is provided on the fixed seat 6. The power component is used to synchronously push all the spring plugs 7 on the same horizontal plane to insert or leave the socket 9, so as to change the elastic support force of the support 3. The elastic insert 7 includes a connecting plate 10, a fixed plate 11, and a movable plate 12. The fixed plate 11 is fixedly disposed at the bottom of the front end face of the connecting plate 10. The movable plate 12 is slidably assembled on the front end face of the connecting plate 10. A miniature spring shock absorber 13 is connected between the fixed plate 11 and the movable plate 12. The rear end face of the connecting plate 10 is mounted on the connecting rod 8.

[0020] In this embodiment, the power assembly includes several connecting pipes 20 and several control valves 21. The fixed base 6 has several moving cavities 22 corresponding to each connecting rod 8. The connecting rod 8 slides through the moving cavity 22, with one end extending to the outside of the fixed base 6 and connected to the elastic plug 7, and the other end connected to the seal 23. A return spring 24 is connected between the connecting rod 8 and the inner wall of the moving cavity 22. The ends of each moving cavity 22 on the same horizontal plane away from the support 3 are connected through the connecting pipes 20. Several control valves 21 are provided on one of the fixed bases 6. One end of the control valve 21 is connected to the corresponding connecting pipe 20, and the other end is connected to an external air source. High-pressure fluid can be introduced into the connecting pipe 20, thereby synchronously pushing all the elastic plugs 7 on the same horizontal plane into the socket 9. A millimeter-wave radar is deployed at the front end of the main body 1 of the vehicle to identify the road conditions ahead and send a signal to the processor. The processor is electrically connected to the control valves 21 and the external air source. When the control valve 21 is opened, high-pressure gas is introduced into the connecting pipe 20 from the external air source. After entering the moving chamber 22, the high-pressure gas pushes the connecting rod 8, causing the movable plate 12 and the fixed plate 11 of the elastic plug 7 to be inserted into the socket 9 as a whole. After insertion, the movable plate 12 contacts the inner wall of the socket 9, and the miniature spring damper 13 is compressed, which will form a superposition effect of rigid support and elastic buffer, improving the local stiffness of the support 3. After the control valve 21 releases the pressure, the reset spring 24 pulls the connecting rod 8 to retract, and the elastic plug 7 exits the socket 9, leaving only the spring damper 4 between the base 2 and the support 3 as a primary buffer.

[0021] When the elastic plug 7 is inserted into the socket 9, its miniature spring damper 13 and the spring damper 4 of the base 2 form a parallel structure, so that the total stiffness of the spring of the support 3 is equal to the sum of the stiffness of the spring damper 4 and the miniature spring damper 13. Moreover, the elastic plug 7 is evenly distributed around the support 3, distributing the weight of the equipment to multiple support points, avoiding the failure of a single spring due to overload. At the same time, the elastic plug 7 inserted at different positions can specifically compensate for the uneven deformation of the support 3 (such as the lateral force when the vehicle is turning).

[0022] The spring damper 4 achieves initial shock absorption between the support 3 and the base 2, while the elastic plug 7 and the socket 9 work together to form a second-level buffer. During operation, the millimeter-wave radar monitors the road conditions ahead (such as the degree of bumpiness) in real time, and the processor controls the power component to simultaneously insert multiple elastic plugs 7 to form a rigid frame and reduce the vibration transmission rate. On smooth road sections, the plugs are removed to restore flexible shock absorption and reduce energy consumption.

[0023] It can also be adaptively adjusted according to the load of the refrigeration unit 5 installed on it. For example, when the weight of the refrigeration unit 5 changes suddenly (such as when the refrigerant is fully loaded), causing the support 3 to collapse, all the spring blocks 7 are inserted to increase the total rigidity and keep the equipment level error ≤0.5°. In the case of no-load transportation or low-power operation, some of the spring blocks 7 are removed to reduce rigidity and reduce energy consumption.

[0024] Here are some application examples in various scenarios: 1. Heavy-duty transportation scenario: With all the elastic plugs 7 inserted, the overall stiffness of the support 3 is increased to 1500 N / mm, which can withstand the impact of peak acceleration 5G, and the equipment displacement is controlled within ±2 mm. 2. Long-distance cold chain transportation: When cruising on flat roads, only 50% of the spring-loaded blocks 7 are used, reducing the overall energy consumption of the shock absorption system by 30% and the equipment operating noise ≤65 dB; 3. Emergency braking or curve conditions: After millimeter-wave radar prediction, the spring block 7 is fully inserted within 0.2 seconds, increasing the lateral support force by 200% to prevent the refrigeration unit 5 from overturning.

[0025] In this embodiment, the first mounting component 37 further includes a base 14, on which the base 2 is movably disposed. The base 14 is mounted on the carriage body 1. Each side end face of the base 2 is provided with a plurality of support rings 15. Adjustment seats 16 are evenly distributed around the top surface of the base 14. A motor 17 is disposed in one end of the adjustment seat 16. A spool 18 is disposed on the output shaft of the motor 17. An elastic rope 19 is disposed on the spool 18. The other end of the elastic rope 19 passes through each support ring 15 on the same side and is fixed to the other end of the adjustment seat 16. The rotation of the spool 18 can wind and unwind the elastic rope 19, thereby adjusting the tension of the elastic rope 19. The base 2 is connected to the base 14 via multiple highly elastic ropes 19. The motor 17 drives the reel 18 to wind up and unwind the ropes, dynamically adjusting the tension. When the carriage turns or tilts, the elastic rope 19 on the stressed side is tightened while the opposite side is loosened, creating a reverse torque to counteract the offset of the base 2 caused by inertial force. Compared to traditional rigid connections, this avoids stress concentration caused by rigid connections and balances the lateral sway generated during carriage movement. Furthermore, the flexible connection of the elastic ropes 19 can withstand 8G instantaneous impact (such as sudden braking), while rigid fixation is prone to bolt breakage or weld cracking due to rigid transmission.

[0026] Meanwhile, when the weight of the refrigeration unit 5 changes, the system automatically adjusts the preload of the elastic rope 19 to ensure that the base 2 is always in a horizontal state, avoiding equipment tilting or resonance due to uneven load.

[0027] In this embodiment, a second mounting assembly for securing the cargo 36 is also included. This second mounting assembly is disposed within the main body 1 of the carriage. The second mounting assembly includes a transport mechanism and a heat insulation mechanism. The transport mechanism includes a pair of sliding rods 25, a pair of upper sliding rods 26, and a drive mechanism. The top and bottom ends of the main body 1 are respectively provided with upper sliding grooves and lower sliding grooves corresponding to the upper sliding rods 26 and the sliding rods 25. The upper sliding rods 26 and the sliding rods 25 are respectively embedded in the upper sliding grooves and the lower sliding grooves. A plurality of sliding seats 27 are slidably connected between the two sliding rods 25, and a [missing information - likely a specific mechanism or component] is slidably connected between the two upper sliding rods 26. Several corresponding upper sliding seats 28 are provided, and several support members 29 are connected between the corresponding upper sliding seats 28 and lower sliding seats 27. The cargo 36 can be placed on the front side of the support member 29. The drive mechanism is set on the top of the carriage body 1, and the upper sliding seats 28 are selectively connected to the drive mechanism, so that the drive mechanism drives the upper sliding seats 28 and their lower support members 29 and lower sliding seats 27 to move horizontally, thereby pushing the cargo 36 to move outward. The heat insulation mechanism includes several heat insulation plates 30, and each heat insulation plate 30 is distributed on the left and right sides inside the carriage body 1, and the heat insulation plate 30 is rotatably installed on the carriage body 1.

[0028] In this embodiment, the driving mechanism includes a belt drive mechanism 31, which is embedded in the middle of the top of the carriage body 1. A plurality of iron blocks 32 are provided on the drive belt of the belt drive mechanism 31. An electromagnet 33 is provided in the middle of the top of the upper slide block 28. When the electromagnet 33 is energized, it can be attracted to the iron blocks 32. The belt drive mechanism 31 is in operation during unloading. When one of the goods 36 needs to be pushed to the door of the carriage body 1 for unloading, the electromagnet 33 on the upper slide 28 corresponding to the goods 36 is energized, causing it to attract the iron block 32. Thus, with the operation of the belt drive mechanism 31, the upper slide 28 is driven to move horizontally, realizing the automated pushing of the goods 36. The staff can complete the unloading without entering the carriage.

[0029] In this embodiment, the support is an elastic band. Both the upper slide 28 and the lower slide 27 have several corresponding mounting holes 34. A support rod 35 is installed in each mounting hole 34. The elastic band is sleeved on the two corresponding upper and lower support rods 35. The elastic band is used to push the cargo 36 in one direction. After the cargo 36 in front of the elastic band is removed, the elastic band is removed to avoid affecting the removal of the cargo 36 behind it. Conversely, during loading, the elastic band is sleeved between the upper slide 28 and the lower slide 27, and then the cargo 36 is placed in front. The squeezing force generated by the continuous insertion of subsequent cargo 36 causes the already positioned cargo 36 to gradually move into the interior of the carriage body 1. During loading, according to the unloading location of the cargo 36, the cargo 36 at the same location is placed in front of the same support 29.

[0030] In this embodiment, a rotating shaft is provided at one end of the heat insulation plate 30. The rotating shaft is rotatably mounted on the body 1 of the carriage. A torsion spring is connected between the rotating shaft and the body 1 of the carriage. When the torsion spring is in a free angular displacement state, the heat insulation plate 30 is parallel to the support member 29, and the width of the heat insulation plate 30 is half the width of the body 1 of the carriage. During the loading of cargo 36, the doors of the existing carriages remain open, preventing the cargo 36 loaded earlier from being refrigerated in a timely manner, thus affecting its quality. During unloading, especially in cases of multiple cargo distribution, the open doors also affect cargo 36 that does not need to be unloaded immediately, thus impacting its quality. However, in this application, the heat insulation plate 30, in its initial state, is parallel to the support member 29 under the free angular displacement of the torsion spring, dividing the interior of the carriage into multiple spaces to form a continuous heat insulation barrier. When the cargo 36 is pushed into the carriage, the outer edge of the cargo 36 contacts the edge of the heat insulation plate 30, applying a thrust to overcome the resistance of the torsion spring and push the heat insulation plate 30 to rotate inward around the rotation axis, making way for the cargo 36 to enter. The heat insulation plates 30 on both sides of the area where the cargo 36 is loaded rotate to 90° and abut against the inner wall of the carriage under the restriction of the cargo 36, thus achieving a heat insulation effect during transportation. During unloading, when the cargo 36 to be unloaded is pulled out, the heat insulation plate 30 in this area loses the restriction of the cargo 36, and the torsion spring automatically resets, causing the heat insulation plate 30 to spring back to the closed state, re-sealing the area and preventing cold air from leaking out. If the following cargo 36 continues to be pushed out, it will push open the closed heat insulation plate 30 in the opposite direction, without affecting the entry and exit of the cargo 36.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
