Description

Technical Field

[0001] The present invention relates to the technical field of cold chain fresh-keeping storage system installation, and in particular to an installation device for an intelligent self-regulating cold chain fresh-keeping storage system. Background Art

[0002] With the rapid development of the global cold chain logistics industry, the demand for the transportation of goods that are extremely sensitive to temperature, such as fresh agricultural products, is increasing day by day. During long-distance transportation, these goods have extremely high requirements for the stability of the storage environment. Slight temperature fluctuations or environmental changes may cause the quality of the goods to deteriorate or even fail. Refrigerated compartments, as the core mobile storage carriers in the cold chain transportation link, bear the heavy responsibility of maintaining the fresh environment of the goods. Their performance is directly related to the final quality and safety of the goods.

[0003] The refrigerated compartment is not an independently operated unit, but needs to be precisely adapted and firmly integrated with the transport vehicle. This process relies on professional refrigerated compartment installation equipment.

[0004] The prior art publication number CN216990676U provides an installation device for an intelligent self-adjusting cold chain preservation storage system, which includes a movable base, the upper portion of the movable base is movably connected by an L-shaped connecting rod and a limiting tube, and a lifting rod is movably installed on the left and right sides of the upper portion of the movable base, and an auxiliary support rod is fixedly installed on the front side of the lifting rod, and a wire receiving box is symmetrically arranged on the left and right sides of the rear side of the movable base, and a pull rope is rolled up inside the wire receiving box, and an L-shaped positioning pull plate is provided at the end of the pull rope. The L-shaped connecting rod is lifted and lowered by the telescopic rod to cooperate with the lifting rod to complete the installation of the preservation box body. The limiting tube is provided to limit the connection of the L-shaped connecting rod to prevent shaking when lifting the preservation box body, and the pull rope is limited by setting the lifting rod and the auxiliary support rod to limit the steering, and the pull rope is stored by the wire receiving box. The L-shaped positioning pull plate fixes and limits the preservation box body, and cooperates with the pull rope to move and lift.

[0005] Although the above-mentioned existing technology uses a hanging rope to install the fresh-keeping box, the device is not flexible enough. In the existing device, on the one hand, due to the large size of the fresh-keeping box, the corresponding installation device is even larger, which is extremely inconvenient to operate in a narrow space and the usage scenarios are severely limited. On the other hand, whether it is a vertical installation method such as hanging rope lifting or cylinder lifting, the required working space is large, and the large installation equipment lacks accuracy in small-range position adjustment. In the actual installation process, it is often difficult to align the fresh-keeping box with the truck installation hole. Once a deviation occurs, the subsequent adjustment is extremely difficult, which seriously affects the installation efficiency and stability.

[0006] It can be seen that an intelligent self-adjusting cold chain fresh-keeping storage system installation device is needed to solve the problems mentioned in the above background technology that the existing devices are bulky and lack flexibility, the vertical installation method requires a large space, and the adjustment accuracy is insufficient.

[0016] Compared with the prior art, the present invention has the following beneficial effects: First, the present invention uses a rotating lifting assembly, a base assembly, a flip assembly, and a telescopic connection assembly to achieve a four-group device that works together to construct a clamping mechanism for the fresh-keeping compartment. The split design effectively overcomes the limitations of traditional installation devices. During installation, the fresh-keeping compartment is first placed on the base assembly. The rotating lifting assembly is driven to rotate the clamp to the side of the fresh-keeping compartment and accurately adjust to the installation height suitable for the truck. The four groups of devices then move synchronously and smoothly to push the fresh-keeping compartment to the truck installation position. Compared with traditional large-scale, one-piece installation equipment, the modular design makes each group of devices compact. The overall footprint of the combined assembly is greatly reduced, allowing for flexible deployment and operation in confined spaces. The side-translational installation method adopted by the present invention abandons the reliance on longitudinal space of the traditional vertical lifting mode, significantly reducing the space required for installation. At the same time, the split structure gives the device powerful position fine-tuning capabilities. Even after the fresh-keeping compartment is initially in place, the mounting holes can still be precisely aligned by independently adjusting each component. This effectively solves the problems of difficult hole alignment and inconvenient later adjustments in traditional installation, greatly improving installation efficiency and user experience.

[0017] Second, the present invention realizes the compound movement of rotation and lifting of the clamp as a whole around the fixed sleeve by setting up a rotating lifting component. The rotation creates sufficient space for loading the fresh-keeping compartment, ensuring smooth access to the fresh-keeping compartment and successful removal of the subsequent clamp. The lifting is to lift the fresh-keeping compartment steadily to a height suitable for the truck cargo platform, laying the foundation for subsequent installation. These two actions are driven by a set of motors. Through the coordination of the mechanical structure, not only a high degree of functional integration is achieved, but also the redundancy of the power system is significantly reduced, which effectively reduces energy consumption. At the same time, the overall weight of the device is greatly reduced, making it more flexible and easy to operate in a small space, significantly improving the operating efficiency and practicality of the equipment.

[0018] Third, the present invention realizes that the unfolding orientation of the flip assembly can be changed by starting the base assembly through the provision of a base assembly and a flip assembly. The flip assembly is connected to a forklift, and is convenient for the forklift to move after unfolding. Because the fresh-keeping compartment needs to be installed in different parts of the truck, such as the front, middle, and rear, the change in position causes the moving path of the forklift to change. In order to facilitate the movement of the forklift, the flip assembly can change its position as the base assembly rotates, and the base assembly will also drive the roller to be stored and unfolded through mechanical cooperation while rotating. The purpose is to facilitate the coordination of the rotation action, reduce the movement resistance of the pulley, and enable the base assembly to rotate better, meeting the installation requirements of the fresh-keeping compartment in different positions of the truck while increasing the practicality and operating experience of the device.

[0019] Fourth, the present invention connects two groups of vertically distributed base components through the provision of a telescopic connection component, thereby building a coordinated moving whole, ensuring that the four groups of devices can move synchronously and stably complete the installation operation. The telescopic connection component has a telescopic function, so when facing fresh-keeping compartments of different sizes, the telescopic connection component can be extended or shortened as needed, accurately adjusting the distance between the two groups of vertical base components, and improving the adaptability and versatility of the device.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-8 , an installation device for an intelligent self-adjusting cold chain fresh-keeping storage system, including a rotating lifting component 2, the bottom end of the rotating lifting component 2 is connected to a base component 3, the rotating lifting component 2 includes a fixed fixed sleeve 201 and a screw rod 202 rotating inside the fixed sleeve 201, a rectangular groove 2011 is opened on the outside of the fixed sleeve 201, the outside of the screw rod 202 is connected to a moving block 205 limited by the rectangular groove 2011, and the outside of the moving block 205 is connected to a moving sleeve 206, and one side of the moving sleeve 206 is connected to a clamp 207 for clamping the fresh-keeping compartment 1.

[0024] In this embodiment, a group of modules is composed of a rotating lifting component 2, a base component 3, and a flip component 4. There are four groups of such modules. The modules on the vertical line are connected by a telescopic connecting component 5. The four groups of modules are respectively arranged on the four sides of the fresh-keeping compartment 1 and are fixed by clamping. After the flip component 4 is unfolded between the two groups of modules on the horizontal line, they can be connected to a forklift at the same time. The forklift pushes the two groups of modules on the horizontal line to move, and then pushes the four groups of modules and the fresh-keeping compartment 1 to move, so that the fresh-keeping compartment 1 can be successfully installed on the truck. The four groups of modules occupy a small area and are flexible to use. Whether in the installation process or in the process of dragging it to the parking point by a forklift after installation, it is more flexible, more applicable and practical than the existing large-scale integrated installation equipment. The operation process of installing the fresh-keeping compartment 1 by translation takes up less space and is more suitable for the operation site. In smaller occasions, a controller is installed in the device, and the controller is electrically connected to the electronic components in the device for easy control. A single module uses a single controller to facilitate separate control of the modules. In this embodiment, the structures between the modules can be different because the four groups of modules are responsible for different tasks. For example, only two groups of modules need to be installed with the flip assembly 4, because during the installation process, the function of the flip assembly 4 is to connect with the forklift, so only two groups of flip assemblies 4 need to be connected to the forklift. Similarly, the mechanical structure of the rotating and lifting pulleys in the base assembly 3 only needs to be installed with the two groups of modules with the flip assembly 4, because the purpose of rotating the base assembly 3 is to adjust the orientation of the flip assembly 4. The modules without the flip assembly 4 do not need to install the functions of the rotating and lifting pulleys in the base assembly 3, and a fixed plate and a fixed pulley can be used.

[0025] Specifically, a first worm gear group 203 is provided at the bottom end of the screw rod 202, and a lifting motor 204 is installed at one end of the first worm gear group 203. The movable block 205 includes a sleeve, a through portion and an arc portion, and the interior of the sleeve is provided with a threaded hole matching the screw rod 202. The outer side of the sleeve is connected with a through portion, and one end of the through portion is connected with an arc portion. The through portion passes through the rectangular groove 2011 and extends to the outside of the fixed sleeve 201, and the arc portion is located on the outside of the fixed sleeve 201. The arc portion is connected to the movable sleeve 206, and the movable sleeve 206 moves on the outside of the fixed sleeve 201. A splint 208 is connected to one side of the clamp 207, and the splint 208 is connected to the side of the fresh-keeping compartment 1.

[0026] In this embodiment, the rectangular groove 2011 includes two groups of transverse grooves and two groups of longitudinal grooves. Since the fixed sleeve 201 is a cylindrical structure, the rectangular groove 2011 opened on the fixed sleeve 201 also presents an arc shape as a whole. A rectangular plate is provided in the middle of the rectangular groove 2011. The rear side of the rectangular plate is connected with a support column and connected to the inner wall of the fixed sleeve 201. The installation of the rectangular plate does not delay the up and down movement and rotation of the movable block 205, nor does it delay the rotation of the screw rod 202. When the fresh-keeping compartment 1 is placed on the four groups of modules, in order not to delay the placement of the fresh-keeping compartment 1, the clamp 207 is rotated to one side to make room for the placement of the fresh-keeping compartment 1, so After the fresh-keeping compartment 1 is placed, the clamp 207 needs to complete two actions, one is to rotate to the side close to the fresh-keeping compartment 1, and the other is to rise to the height matching the truck. After starting the lifting motor 204, these two actions can be completed. First, when the screw rod 202 rotates in the horizontal groove of the limit slot, the moving block 205 will not rise or fall, but move along the horizontal groove. This action will drive the moving sleeve 206 and the clamp 207 to rotate, and when the moving block 205 rotates to one end of the horizontal groove, it will enter the longitudinal groove connected to the horizontal groove. At this time, with the limit of the longitudinal groove, the moving block 205 will drive the moving sleeve 206 and the clamp The tool 207 rises, and when it rises to the highest point, that is, the height matching the truck cargo platform, it continues to rotate, and the moving block 205 enters the top transverse groove from the longitudinal groove and rotates according to the set trajectory of the transverse groove. Then the moving block 205 descends along another set of longitudinal grooves, which corresponds to the action of the splint 208 leaving the fresh-keeping compartment 1 and rotating to the other direction, and then descending to return to the origin. The rotation and lifting actions are completed by a set of motors, saving power source. In this embodiment, the length of the longitudinal groove in the rectangular groove 2011 matches the height of the truck, and the screw rod 202 can adopt a reciprocating screw rod, so that the lifting motor 204 adopts a servo motor. The servo motor can drive the moving block 205 to rise and fall by rotating in one direction. A forward and reverse motor can also be used. After starting, it drives the screw rod 202 to rotate forward and reverse, thereby driving the moving block 205 to rise and fall. The purpose of setting the first worm gear group 203 is to self-lock to prevent the moving block 205 from moving due to weight when there is no driving of the lifting motor 204. The fixed sleeve 201 passes through the rotating plate group 302, the connecting tube 3022 and extends to the inside of the fixed base plate 301. When the rotating plate group 302 rotates, it will not affect the rotating lifting assembly 2. The bottom of the fixed sleeve 201 is set in an incomplete cylindrical structure for easy installation.

[0027] See also Figure 4-10The lifting mechanism 302 is a kind of lifting mechanism that is used for lifting and lowering the lifting mechanism 303, and the lifting mechanism 303 is a kind of lifting mechanism 304 that is used for lifting and lowering the lifting mechanism 303.

[0028] In this embodiment, when the rotating plate group 302 needs to rotate, the fresh-keeping compartment 1 has been clamped by the clamping plate 208 and placed on the truck platform. Therefore, when the rotating plate group 302 rotates and drives the roller 3037 to be stored, the fixed bottom plate 301 is in a suspended state, and the rotating lifting component 2 reversely supports the base component 3. The rotation at this time will not generate friction with the ground because the roller 3037 in contact with the ground has been stored, thereby making the use process of the device reasonable.

[0029] Specifically, the rotating plate group 302 includes a plate body 3021, and the bottom end of the plate body 3021 is connected to a connecting tube 3022, the bottom end of the connecting tube 3022 is connected to a half gear 3023, a pulley group 3024 is provided below the half gear 3023, and a gear group 3025 is connected above one set of pulleys in the pulley group 3024, a rotating motor 3026 is installed above the gear group 3025, and a gear ring 3027 is provided on one side of the gear group 3025, an internal gear 3028 meshing with it is provided at an eccentric point inside the gear ring 3027, and the top of the internal gear 3028 is connected to a worm gear 3029 through a pulley group.

[0030] In this embodiment, incomplete teeth are arranged on the outer side of the half gear 3023, and incomplete teeth are also arranged on the inner side of the gear ring 3027, and the internal gear 3028 is located between the half gear 3023 and the gear ring 3027. The timing of the engagement of the half gear 3023 and the gear ring 3027 with the internal gear 3028 is staggered, so it will drive the internal gear 3028 to rotate forward and backward. The forward and reverse rotation of the internal gear 3028 will drive the roller 3037 to store and lower it, so that during the process of the rotating plate group 302 rotating 180 degrees, the roller 3037 has completed the storage and lowering action. After the rotation is completed, the roller 3037 also completes the lowering action, so that the roller 3037 contacts the ground, which will not affect the subsequent pushing action.

[0031] Specifically, the connecting cylinder 3022 is a hollow structure, and an empty groove is provided inside the half gear 3023, the outer side of the gear ring 3027 is provided with complete teeth, and the inner side of the gear ring 3027 is provided with incomplete teeth. The outer teeth of the gear ring 3027 are meshed with the gear set 3025, and the incomplete teeth inside the gear ring 3027 are meshed with the internal gear 3028, and the internal gear 3028 is also meshed with the half gear 3023.

[0032] In this embodiment, the pulley group 3024 and gear group 3025 are set to keep the gear ring 3027 and the half gear 3023 rotating in the same direction. There are two gear groups 3025, one of which is in contact and meshing with the teeth on the outside of the gear ring 3027, and the teeth on the inside of the half gear 3023 and the gear ring 3027 are facing opposite directions. In this embodiment, the top of the internal gear 3028 is connected to a group of pulley groups through an axis, wherein a group of worm wheels 3029 are respectively provided above the two groups of pulleys, and the two groups of worm wheels 3029 are respectively engaged with a group of worm gears 3031, so that the two groups of worm gears 3031 will be driven to rotate, and the reversal between the worm gear 3031 and the worm wheel 3029 can be avoided, thereby preventing the gear ring 3027 from being reversed due to gravity in the absence of driving force.

[0033] Specifically, the lifting wheel group 303 includes a worm 3031, and the worm 3031 is located on the side of the top of the fixed base plate 301, and the two ends of the worm 3031 are respectively connected to a group of rotating blocks 3032, and the rotating block 3032 is hinged to the rectangular block 3033 inside, and the outer side of the rectangular block 3033 is hinged to the hinge block 3034, and one end of the hinge block 3034 is connected to the rotating shaft 3035, the rotating shaft 3035 and the wheel axle 3036 are fixedly connected, and the roller 3037 rotates at the bottom end of the wheel axle 3036, a groove is opened on the fixed base plate 301, and the wheel axle 3036 and the roller 3037 move in the groove.

[0034] In this embodiment, both ends of the worm 3031 drive a group of rollers 3037 to be stored and lowered respectively, and there are two groups of worms 3031, so four groups of rollers 3037 can be driven to be stored and lowered synchronously.

[0035] Specifically, the flip assembly 4 includes a flip rod 401, and one end of the rear side of the flip rod 401 is connected to a rotating shaft 402, the flip rod 401 is hinged to one side of the fixed block 408 through the rotating shaft 402, the rear side of the flip rod 401 is connected to a back shaft 403, and the back shaft 403 is provided with a groove for the limit block 404 to move, one end of the limit block 404 is connected to a drive shaft 405, and one end of the drive shaft 405 is connected to a short shaft 406, the bottom end of the short shaft 406 is connected to a second worm gear group 407, and the second worm gear group 407 is installed inside the fixed block 408, and the fixed block 408 is fixed to one side of the rotating plate group 302.

[0036] In this embodiment, the unfolding range of the flip assembly 4 is 0-90 degrees. The unfolding process includes starting the second worm gear assembly 407, which can drive the short shaft 406 to rotate, the short shaft 406 drives the driving shaft 405 to rotate, and the driving shaft 405 drives the back shaft 403 to rotate, so that the limit block 404 moves in the groove in the back shaft 403, and the back shaft 403 drives the flip rod 401 to rotate, so that the flip rod 401 rotates with the rotating shaft 402 as the rotation point. After the flip rod 401 rotates ninety degrees, it can be rotated from the rotating plate assembly 302. One side is unfolded, thereby shortening the distance between the two sets of horizontal lines, making it easier to connect with a forklift, thereby facilitating the forklift to push and apply force. Since the flip rod 401 is connected to the forklift, the flip rod 401 can be made of a metal material with strong pressure resistance. Due to different reasons for the assembly of the forklift, a connecting structure that matches the forklift can be assembled on the flip rod 401, such as a connecting ring, etc. In actual installation operations, the possible installation situations that may occur include: the fresh-keeping compartment 1 matches the area of ​​the truck platform or the area of ​​the fresh-keeping compartment 1 is smaller than the truck platform. When the fresh-keeping compartment 1 is When 1 matches the area of ​​the truck platform, the forklift located at the rear side of the truck can push the fresh-keeping compartment 1 to load the materials. When the area of ​​the fresh-keeping compartment 1 is smaller than the truck platform, the fresh-keeping compartment 1 will be installed in different positions of the platform, including at the front, middle and rear of the platform. The installation situation at the rear is the same as when the area matches. Similarly, the forklift is located at the rear side of the truck, but when the fresh-keeping compartment 1 needs to be installed at the front or middle of the platform, the flip assembly 4 cannot move on the truck chassis due to the obstruction of the wheels, so the forklift cannot advance. At this time, the fixed bottom plate 301 can only be rotated to make the flip assembly 4 turn its direction and be located on the side of the truck, so that it can keep in touch with the forklift and push the fresh-keeping compartment 1 to move. At this time, two forklifts can be started to advance synchronously from both sides of the truck, or a group of forklifts can be used to advance. Due to the clamping relationship of the module to the fresh-keeping compartment 1, the other three groups of modules will drive the fresh-keeping compartment 1 to move together. In order to keep the hole positions aligned, when a group of forklifts moves the fresh-keeping compartment 1 to the approximate position, it can move to the other side and slowly align and adjust.

[0037] See also Figure 11-12 , an installation device for an intelligent self-adjusting cold chain fresh-keeping storage system, a telescopic connection component 5 is connected to one side of the base component 3, and the telescopic connection component 5 is used to connect two groups of base components 3 in the vertical direction, the number of rotating lifting components 2, base components 3, and flip components 4 are all four, respectively located on the four sides of the fresh-keeping compartment 1.

[0038] In this embodiment, since the two groups of base components 3 on the vertical lines need to be connected through the telescopic connection component 5 during propulsion, the telescopic connection component 5 can be made of metal material with strong pressure resistance to extend the service life. Among the four groups of modules, two groups of telescopic connection components 5 can be equipped to balance the moving trajectory of the module.

[0039] Specifically, the telescopic connection assembly 5 includes a telescopic motor 501, and the telescopic motor 501 is connected to a first hinge shaft 503 through a third worm gear assembly 502. One end of the first hinge shaft 503 is connected to a first gear 5031, and an auxiliary hinge shaft 505 is provided below the first hinge shaft 503. One end of the first gear 5031 and the auxiliary hinge shaft 505 are jointly hinged on a first hinge block 506, and the first hinge block 506 is also hinged to a first hinge block 506. There are two first gears 5041, one side of the second first gear 5041 is connected to the second hinge shaft 504, and the tail end of the second hinge shaft 504 is connected to the second tail gear 5042, the second tail gear 5042 is hinged on the second hinge block 508, and the second hinge block 508 is also hinged to the third hinge shaft 507, one end of the third hinge shaft 507 is hinged to the third hinge block 510, and the third hinge block 510 is also hinged to the fourth hinge shaft 509.

[0040] In this embodiment, the telescopic connection assembly 5 is installed on one side of the fixed base plate 301. The fixed base plate 301 does not rotate, so it will not affect the telescopic connection assembly 5. The telescopic motor 501 can be a servo motor. After starting, it drives the third worm gear set 502 to rotate. The third worm gear set 502 plays a role in preventing reverse rotation, which can prevent the telescopic connection assembly 5 from telescoping without the drive of the telescopic motor 501. The first hinge shaft 503 and the first gear 5031 are fixedly connected. Therefore, when the first hinge shaft 503 rotates, the first gear 5031 will also rotate. Similarly, the second first gear 5041 and the second tail gear 5042 have the same connection relationship with the second hinge shaft 504, and the third hinge shaft 507 and the fourth hinge shaft 509 have the same connection relationship with the gears therein. The first gear 5031 meshes with the second first gear 5041 to convert the rotational motion into linear telescopic motion, thereby realizing the length adjustment function of the telescopic connection assembly 5.

[0041] Specifically, one end of the first hinge shaft 503 and the auxiliary hinge shaft 505 are hinged on the vertical plate, and the vertical plate is installed on the fixed base plate 301. The first gear 5031 is meshed with the second first gear 5041. There are multiple groups of auxiliary hinge shafts 505, one of which is hinged between the first hinge block 506 and the second hinge block 508, and is located above the second hinge shaft 504. Another group of auxiliary hinge shafts 505 is hinged between the second hinge block 508 and the third hinge block 510, and is located below the third hinge shaft 507. The third hinge shaft 507 has the same structure as the second hinge shaft 504, and a group of gears are respectively provided at the head and tail, and the head gear is meshed with the second tail gear 5042, and the tail gear is meshed with the gear in the fourth hinge shaft 509. The head of the fourth hinge shaft 509 is connected with a gear, and the tail is hinged to another group of vertical plates.

[0042] In this embodiment, after the telescopic motor 501 is started, the first hinge shaft 503, the second hinge shaft 504, the third hinge shaft 507 and the fourth hinge shaft 509 will each rotate around the hinge point, and form a symmetrical structure in pairs. For example, when the telescopic connection assembly 5 is controlled to retract, a "╱╲"-shaped structure is formed between the first hinge shaft 503 and the second hinge shaft 504, and a "╱╲"-shaped structure is also formed between the fourth hinge shaft 509 and the third hinge shaft 507. The telescopic connection assembly 5 will change from a "one" shape to a "╱╲╱╲" shape from expansion to retraction. As the retraction distance increases, the rotation angle of each hinge shaft increases until it rotates from a horizontal state to a vertical state. The length in the accompanying drawings does not limit the actual extendable length of the telescopic connection assembly 5. The actual length of the telescopic connection assembly 5 can be determined according to on-site construction needs. Each hinge shaft transmits torque through gear meshing, causing adjacent hinge shafts to rotate synchronously to achieve length change of the telescopic assembly.

[0043] When in use, it is necessary to connect an external power supply, which provides electrical energy for the device so that the device can operate normally. First, the longitudinal distance between the four groups of modules is adjusted according to the length of the fresh-keeping compartment 1, and the telescopic motor 501 is started, so that the telescopic motor 501 drives the first hinge shaft 503 to rotate through the third worm gear group 502. The first hinge shaft 503 rotates with the end in contact with the third worm gear group 502 as the center point, thereby driving the first hinge block 506 to move, and the auxiliary hinge shaft 505 provides auxiliary support. The first gear 5031 rotates while moving around the center point, thereby driving the second gear 5041 to rotate, and the second gear 5041 drives The second hinge shaft 504 rotates, causing the second hinge shaft 504 to tilt in a mirror image with the first hinge shaft 503. At this time, the second hinge block 508 translates, and the second tail gear 5042 installed on the rear side of the second hinge block 508 drives the third hinge shaft 507 to rotate due to the engagement. The third hinge shaft 507 tilts parallel to the first hinge shaft 503. The third hinge shaft 507 drives the fourth hinge shaft 509 to rotate through engagement, thereby causing the vertical plate at one end of the fourth hinge shaft 509 to translate, thereby causing the telescopic connection assembly 5 to fold or unfold as a whole, adjusting the distance between the two groups of base assemblies 3 in the vertical direction to match the length of the fresh-keeping compartment 1; After the adjustment is completed, the fresh-keeping compartment 1 is placed on the four-group base assembly 3, and the lifting motor 204 is started, so that the lifting motor 204 drives the first worm gear group 203 to rotate, and then drives the screw rod 202 to rotate. When the moving block 205 is located in the lower transverse groove of the rectangular groove 2011, as the screw rod 202 rotates, it will move in the transverse groove, and according to the trajectory set in the transverse groove, it will drive the moving sleeve 206 and the clamp 207 to rotate, so that it rotates from the direction away from the fresh-keeping compartment 1 to the direction close to the fresh-keeping compartment 1, and then the fresh-keeping compartment 1 is clamped by the clamping plate 208. As the moving block 205 moves to the end of the transverse groove, the moving block 205 will move vertically according to the trajectory set in the longitudinal groove, driving the fresh-keeping compartment 1 to rise until it matches the height of the truck. The unfolded flip assembly 4 is connected to the forklift. Under the propulsion of the forklift, the four modules and the fresh-keeping compartment 1 will move synchronously until the fresh-keeping compartment 1 is moved horizontally from the rear end of the truck to the truck; If the length of the fresh-keeping compartment 1 matches the truck, or it needs to be installed at the rear of the truck, the fresh-keeping compartment 1 can be adjusted to the hole position to exit. If the fresh-keeping compartment 1 needs to be installed in the middle of the truck, it will be impossible to continue to push it from the end of the truck. At this time, it is necessary to retract the flip assembly 4 and then start the rotating motor 3026. The rotating motor 3026 drives the gear set 3025 to rotate, which in turn drives the gear ring 3027 to rotate, and also drives the half gear 302 through the pulley set 3024. 3 rotates, and the half gear 3023 drives the plate 3021 to rotate through the connecting tube 3022, thereby driving the flip assembly 4 to adjust its direction and rotate it from the rear of the truck to the side of the truck. Because the half gear 3023 and the gear ring 3027 are both engaged with the internal gear 3028, but the teeth are facing different directions, so when the half gear 3023 contacts the internal gear 3028, the gear ring 3027 does not contact the internal gear 3028. At this time, the internal gear 3028 rotates in the forward direction, and when the gear ring 3027 When the half gear 3023 contacts the inner gear 3028, the half gear 3023 does not contact the inner gear 3028. At this time, the inner gear 3028 rotates in the opposite direction, and the rotation of the inner gear 3028 drives the worm wheel 3029 to rotate. The worm wheel 3029 meshes with the worm 3031, so the worm 3031 rotates accordingly. The rotation of the worm 3031 drives the rotating shaft 3035 to rotate through the rotating block 3032, the rectangular block 3033 and the hinge block 3034, so that the wheel shaft 3035 inserted in the rotating shaft 3035 is rotated. 36 will rotate at the insertion point, thereby driving the roller 3037 to rotate, so that the roller 3037 is stored or unfolded. When the roller 3037 is stored and not in contact with the ground, the worm 3031 is rotating, and after the worm 3031 rotates into place, the roller 3037 is lowered again. This combination makes it convenient for the worm 3031 to smoothly drive the flip assembly 4 to rotate to the side of the truck. When the flip assembly 4 is located on the side of the truck, the forklift can easily push the module from the side, making it convenient for the fresh-keeping compartment 1 to move to the middle position of the truck.
