Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, and in particular to a storage and transportation system and a connection method. Background Technology

[0002] Currently, sterile medical devices are mainly transported, loaded, and unloaded manually. This involves manually moving individual sterile medical devices of varying sizes and weights, consisting of metal instrument cases, bags, and pouches, into a vehicle, transporting them to a designated location, and then manually unloading them one by one. This traditional method is not only time-consuming and labor-intensive, but also prone to damage and contamination of instrument bags and pouches due to repeated loading and unloading. More efficient and safer transportation and loading / unloading equipment is needed to address these issues. Summary of the Invention

[0003] The purpose of this invention is to provide a more efficient and safer storage and transportation device.

[0004] To achieve the above objectives, the present invention provides a storage and transportation system, including a transfer vehicle, a flatbed trolley, a floor-mounted bracket, and shelves; the transfer vehicle is equipped with casters at its bottom, and at least two first guide rails are mounted on the inner bottom surface of the transfer vehicle's compartment; the flatbed trolley is equipped with casters at its bottom, and at least two second guide rails are mounted on its bottom plate; the floor-mounted bracket's support legs are fixed below its base plate, and at least two third guide rails are mounted above its base plate; the shelf's size is not larger than the size of the vehicle compartment, and at least two rows of pulleys are mounted on its bottom; wherein the spacing between the at least two first guide rails, the at least two second guide rails, and the at least two third guide rails is equal to the spacing between the at least two rows of pulleys, and the mounting surfaces of the first, second, and third guide rails are at the same height from the ground, so that the pulleys can slide on any of the guide rails.

[0005] In one embodiment, a first thrust member higher than the third guide rail is fixed to one end of the third guide rail, a first locking member is installed on the bracket base plate, and a first elastic member is installed between the first locking member and the bracket base plate; wherein, the first locking member is used to extend out of the bottom of the bracket base plate by the elastic force of the first elastic member, and the first thrust member and the first locking member are used to limit the displacement of the shelf on the bracket base plate.

[0006] In another embodiment, a double door is installed on the side of the carriage, and the sliding direction of the first guide rail is consistent with the opening and closing direction of the double door.

[0007] In another embodiment, a second thrust member higher than the first guide rail is fixed on the side of the first guide rail away from the double doors, and a second locking member is installed on the side of the first guide rail close to the double doors. A second elastic member is installed between the second locking member and the carriage. The second locking member is used to extend out of the bottom of the carriage under the elastic force of the second elastic member, and the second thrust member and the second locking member are used to limit the displacement of the shelf within the carriage.

[0008] For example, the opening angle of the double doors is 240 to 270 degrees.

[0009] In another embodiment, the trolley base plate is also equipped with an operating lever and a telescopic locking structure located at the bottom. A third thrust member higher than the second guide rail is installed at one end of the second guide rail. The middle part of the operating lever is rotatably connected to the trolley base plate. The operating lever is in contact with the telescopic locking structure. When one end of the operating lever is rotated under force, it pushes the extension and retraction of the telescopic locking structure. This is so that when the telescopic locking structure extends, it restricts the displacement of the frame on the second guide rail with the third thrust member.

[0010] In one embodiment, the other end of the operating lever is provided with a toggle lever. When one end of the operating lever is rotated under force, the toggle lever is used to: push the first locking member to overcome the elastic force of the first elastic member and hide in the bottom of the trolley floor, so that the shelf located on the floor bracket can be pushed onto the flatbed trolley; or, push the second locking member to overcome the elastic force of the second elastic member and hide in the bottom of the carriage, so that the shelf located on the flatbed trolley can enter the carriage.

[0011] In another embodiment, a push handle is installed on the side of the trolley base plate; the force-bearing end of the operating lever has a continuous zigzag structure, which extends the force-bearing end of the operating lever to the push handle of the flatbed trolley.

[0012] In one embodiment, a braking structure is installed on the trolley base near the casters. The braking structure includes a foot pedal, a drive shaft, a retaining ring, two guide grooves, two brake plates, and two brake levers. The casters of the flatbed trolley include wheel frames and tires. The retaining ring is fixed to the bottom of the flatbed trolley. The drive shaft is rotatably connected to the retaining ring. Two radial flanges are respectively provided at the two ends of the drive shaft. The foot pedal is fixedly connected to the middle of the drive shaft. The two guide grooves are respectively fixedly connected to the casters of the two flatbed trolleys. The installation distance between the two guide grooves is equal to the wheel track of the casters of the two flatbed trolleys. The two guide grooves are placed vertically. The two brake plates are respectively rotatably connected to the two wheel frames. One end of the brake plate is located on the movement path of the brake lever. When the foot pedal is subjected to force, it drives the radial flanges to rotate, causing the brake lever to press against one end of the brake plate until the brake plate rotates to contact the tire.

[0013] In a second aspect, this application also provides a connection method applicable to the storage and transportation system of any embodiment, wherein a shelf containing items to be transported is placed on a floor tray. The connection method may include: bringing a flatbed trolley close to the shelf so that the second track is aligned with the third track; pushing the shelf onto the flatbed trolley; opening the compartment and bringing the flatbed trolley carrying the shelf close to the compartment so that the first track and the second track are aligned; pushing the shelf into the compartment; and closing the compartment.

[0014] The present invention discloses a storage and transportation system and a connection method, the advantages of which are as follows:

[0015] This solution eliminates the need for manual handling of goods to different storage and transportation facilities, improving efficiency and reducing the risk of damage by minimizing the number of handling operations. Its application in medical storage and transportation can reduce the probability of package breakage and contamination, demonstrating promising prospects. Attached Figure Description

[0034] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0035] In the description of this invention, it should be understood that the term "storage and transportation equipment" used in this invention can refer to any equipment in the storage and transportation system 1, and does not specifically refer to any particular equipment.

[0036] like Figure 1As shown, the preferred embodiment of the storage and transportation system 1 of the present invention includes a transfer vehicle 10, a flatbed trolley 11, a floor-standing bracket 12, and a shelf 13. The transfer vehicle 10 is equipped with casters at its bottom, and at least two first guide rails 102 are mounted on the inner bottom surface of the vehicle compartment. The flatbed trolley 11 has casters at its bottom of its trolley base 111, and at least two second guide rails 112 are mounted on its base. The support legs 121 of the floor-standing bracket 12 are fixed below the bracket base 122, and a support frame is mounted above the bracket base 122. At least two third guide rails 123; the size of the shelf 13 is not greater than the size of the carriage, and the bottom of the shelf 13 is equipped with at least two rows of pulleys 131; wherein the arrangement spacing of at least two first guide rails 102, at least two second guide rails 112, and at least two third guide rails 123 is equal to the arrangement spacing of at least two rows of pulleys 131, and the mounting surfaces of the first guide rails 102, second guide rails 112, and third guide rails 123 are at the same height from the ground, so that the pulleys 131 can slide on any guide rail.

[0037] Since the first guide rail 102, the second guide rail 112 and the third guide rail 123 installed on different storage and transportation equipment are at the same height, when two of the guide rails are aligned, pushing the shelf 13 can complete the movement of the entire shelf 13 in one go. The transfer of the shelf 13 means that the goods on the entire shelf 13 have been transferred, which greatly improves the efficiency of goods transfer.

[0038] The above solution eliminates the need to manually move goods to different storage and transportation equipment one by one, improving efficiency. At the same time, it reduces the risk of damage to goods by reducing the number of times they are moved. When applied to medical storage and transportation, it can reduce the probability of package breakage and contamination, and has good application prospects.

[0039] Since the shelf 13 is placed directly on each guide rail, there is a certain risk of sliding. To address this, this application provides a series of structures to reduce the risk of sliding and simplify the operation steps.

[0040] In one embodiment, such as Figure 2 As shown, a first thrust member 124 protruding from the third guide rail 123 is fixed at one end of the third guide rail 123, a first locking member 125 is installed on the bracket base plate 122, and a first elastic member 126 is installed between the first locking member 125 and the bracket base plate 122; wherein, the first locking member 125 is used to extend out of the bottom of the bracket base plate 122 by the elastic force of the first elastic member 126, and the first thrust member 124 and the first locking member 125 are used to limit the displacement of the shelf 13 on the bracket base plate 122.

[0041] Through the above scheme, the combined action of the first thrust member 124 and the first locking member 125 can restrict the sliding of the pulley 131 on the third guide rail 123. The presence of the first elastic member 126 allows the locking member to open or close in a timely manner, thereby achieving the fixation or movement of the shelf 13, and enabling the application conversion between handling and transportation scenarios.

[0042] It is understood that the first thrust member 124 and the first locking member 125 can be used to abut against any structure on the shelf 13, such as the pulley 131, the frame side of the shelf 13, the bottom structure of the shelf 13, etc., and this application does not impose any restrictions.

[0043] In another embodiment, a double door 103 is installed on the side of the carriage, and the sliding direction of the first guide rail 102 is consistent with the opening and closing direction of the double door 103.

[0044] In another embodiment, such as Figure 3 As shown, a second thrust member 104 higher than the first guide rail 102 is fixed on the side of the first guide rail 102 away from the double door 103. A second locking member 105 is installed on the side of the first guide rail 102 close to the double door 103. A second elastic member 106 is installed between the second locking member 105 and the carriage. The second locking member 105 is used to extend out of the bottom of the carriage under the elastic force of the second elastic member 106. The second thrust member 104 and the second locking member 105 are used to limit the displacement of the shelf 13 in the carriage.

[0045] The cooperation between the second thrust member 104 and the second locking member 105 allows the shelf 13 to be locked inside the carriage, while the second elastic member 106 allows the second locking member 105 to be compressed, thereby enabling the shelf 13 to be transferred between different components.

[0046] To facilitate the operation of the transfer shelf 13, the opening angle of the double doors 103 can be, for example, 240 to 270 degrees. The large opening angle allows the carriage opening to be fully exposed while there is still some standing space on both sides of the double doors 103, which facilitates the operation of the flatbed trolley 11 or the shelf 13 during the transfer process.

[0047] In addition, magnets can be installed on the outside of the carriage. The double doors 103 are made of magnetic metal. When the double doors 103 are opened, the magnets located on the outside of the carriage can attract the double doors 103, so that the double doors 103 can be stably attached to both sides of the carriage, which is convenient for personnel to operate and prevents the double doors 103 from shaking and injuring goods, operators or storage and transportation equipment.

[0048] In another embodiment, such as Figure 4As shown, the trolley base plate 111 is also equipped with an operating lever 113 and a telescopic locking structure 114 located at the bottom. A third thrust member 115 higher than the second guide rail 112 is installed at one end of the second guide rail 112. The middle part of the operating lever 113 is rotatably connected to the base plate. The operating lever 113 is in contact with the telescopic locking structure 114. When one end of the operating lever 113 is rotated under force, it pushes the telescopic locking structure 114 to extend and retract. When the telescopic locking structure 114 extends, the telescopic locking structure 114 and the third thrust member 115 restrict the displacement of the shelf 13 on the second guide rail 112.

[0049] For example, the telescopic locking structure 114 may adopt a structure similar to that of the first locking member 125 and the second locking member 105.

[0050] For example, the telescopic locking structure 114 may include a push rod located on the operating lever 113, a locking member capable of abutting the push rod, and an elastic member directly mounted on the trolley base plate 111. When the operating lever 113 rotates in the positive direction, the push rod separates from the locking member, and the locking member extends from the trolley base plate 111 under the elastic force of the elastic member; when the operating lever 113 rotates in the reverse direction, the push rod abuts against the locking member and pushes the locking member against the elastic force of the elastic member, causing the locking member to retract into the trolley base plate 111.

[0051] In the exemplary drawings of this application, the positive direction is clockwise and the negative direction is counterclockwise. The positive and negative directions can also be varied according to the actual installation position.

[0052] In one embodiment of this application, a protruding structure 132 can be provided at the bottom of the shelf 13 to reduce the length requirements of the first locking member 125, the second locking member 105 and the telescopic locking structure 114. The first locking member 125, the second locking member 105 and the telescopic locking structure 114 can easily abut against the shelf 13 through the protruding structure 132 to complete the locking.

[0053] In one embodiment of this application, as Figure 5 As shown, the other end of the operating lever 113 is also provided with a toggle lever 1131. When different storage and transportation equipment are close together, the toggle lever 1131 has different functions:

[0054] like Figure 6 As shown, when the flatbed trolley 11 approaches the floor bracket 12, when one end of the operating lever 113 is rotated under force, the actuating lever 1131 is used to push the first locking member 125 to overcome the elastic force of the first elastic member 126 and hide in the bottom of the trolley base plate 111, so that the shelf 13 located on the floor bracket 12 can be pushed onto the flatbed trolley 11.

[0055] like Figure 7As shown, when the flatbed trolley 11 approaches the transfer vehicle 10, when one end of the operating lever 113 is rotated under force, the actuating lever 1131 is used to push the second locking member 105 to overcome the elastic force of the second elastic member 106 and hide in the bottom of the carriage, so that the shelf 13 located on the flatbed trolley 11 can enter the carriage.

[0056] With the above solution, when the flatbed trolley 11 approaches the floor support 12, personnel can simultaneously open or close the telescopic locking structure 114 on the flatbed trolley 11 and the first thrust member 124 on the floor support 12 using the operating lever 113. Therefore, when it is necessary to transfer the shelf 13 between the flatbed trolley 11 and the transfer cart 10, the locking structure of both storage and transportation devices can be opened with a single operation, and then the shelf 13 can be pushed in along the guide rail. Personnel do not need to move or bend over; they can complete the locking after the transfer by operating the operating lever 113 again in place, greatly saving the transfer steps and reducing the number of personnel required. At the same time, one operating lever 113 operates two storage and transportation devices, eliminating the need to install operating levers 113 on each storage and transportation device, thus saving costs.

[0057] It is understood that in any embodiment of this application, the elastic element, the first elastic element 126, and the second elastic element 106 can be either elastic devices that provide pressure (such as torsion springs or pressure springs) or elastic devices that provide tension (such as tension springs or rubber bands). By appropriately modifying the mounting structure of the elastic device, the solution of this application can be applied to elastic devices of different forms and specifications. Adaptive adjustments that can be made by those skilled in the art based on the disclosure of this application, and the solutions obtained after the adjustments should also fall within the protection scope of this application.

[0058] Therefore, in one embodiment, the elastic element, the first elastic element 126 and the second elastic element 106 may be elastic devices of the same form but different specifications.

[0059] In another embodiment, the same type and specifications of elastic device may also be used.

[0060] In one embodiment of this application, as Figure 8 As shown, a push handle 116 is installed on the side of the trolley base plate 111; the force-bearing end of the operating lever 113 is a continuous broken line structure 1132, which extends the force-bearing end of the operating lever 113 to the push handle 116 of the flat trolley 11.

[0061] By designing a continuous zigzag structure 1132, the operating lever 113 is extended to a position close to the push handle 116, making the push-pull operating lever 113 more ergonomic. The operating lever 113 can be pushed and pulled without bending over, and being away from the ground makes operation and disinfection easier.

[0062] Meanwhile, the extension of the operating lever 113 increases the lever arm. According to the torque formula, a longer lever arm means that for the same torque requirement, the force required to be applied to the operating lever 113 is smaller. Therefore, extending the operating lever 113 to a position close to the push handle 116 using the continuous broken line structure 1132 also saves effort.

[0063] In one embodiment, such as Figure 9a and Figure 9b As shown, a braking structure 117 is installed on the trolley base plate 111 near the casters. The braking structure 117 includes a foot pedal 1171, a drive shaft 1172, a retaining ring 1173, two guide grooves, two brake plates 1175, and two brake levers 1174. The casters of the flatbed trolley 11 include wheel frames 1091 and tires 1092. The retaining ring 1173 is fixed to the bottom of the flatbed trolley 11. The drive shaft 1172 is rotatably connected to the retaining ring 1173. Two radial flanges 11721 are respectively provided at both ends of the drive shaft 1172. The foot pedal 1171 is fixedly connected to the drive shaft. In the middle of 1172, two guide grooves are fixedly connected to the casters of two flatbed trolleys 11 respectively. The installation distance between the two guide grooves is equal to the wheel track of the casters of the two flatbed trolleys 11. The two guide grooves are placed vertically. Two brake plates 1175 are rotatably connected to two wheel frames 1091 respectively. One end of the brake plate 1175 is located on the movement path of the brake lever 1174. When the foot pedal 1171 is subjected to force, it drives the radial flange 11721 to rotate, so that the brake lever 1174 presses against one end of the brake plate 1175 until the brake plate 1175 rotates to contact the tire 1092.

[0064] With the above scheme, when the foot pedal 1171 is pressed, the two radial flanges 11721 on the drive shaft 1172 can simultaneously drive the two brake levers 1174 to move downward, so that the two brake plates 1175 respectively lock the two casters 109, thereby achieving simultaneous braking of the casters 109 on both sides. It can also effectively brake when fully loaded. The braking of the two brake levers 1174 and the two brake plates 1175 ensures that the casters 109 do not slip after stopping.

[0065] Meanwhile, the foot pedal 1171 is used for one-button braking, making braking easier and convenient to operate while pushing.

[0066] Correspondingly, the braking structure 117, consisting of the foot pedal 1171, drive shaft 1172, retaining ring 1173 and two brake levers 1174, can also be installed on the transfer vehicle 10 to stop the casters of the transfer vehicle 10.

[0067] In one embodiment of this application, a manual door lock structure 107 may also be installed at the door seam on one of the doors of the double doors 103, such as... Figure 10As shown, the manual door lock structure 107 may include a guide shell 1071, a turntable 1072, an upper latch bar 1073, a lower latch bar 1074, and a rotary handle 1075. The guide shell 1071 has a guide groove for the upper latch bar 1073 and the lower latch bar 1074 to move up and down. The turntable 1072 is rotatably connected to the guide shell 1071. The bottom of the upper latch bar 1073 and the top of the lower latch bar 1074 are respectively rotatably connected to two holes symmetrically distributed on the turntable 1072. One end of the rotary handle 1075 is fixedly connected to the turntable 1072. When the rotary handle 1075 is swung downwards under force, it drives the turntable 1072 to rotate, thereby driving the upper latch bar 1073 to insert upwards into the fixed hole on the upper edge of the door frame and driving the lower latch bar 1074 to insert downwards into the fixed hole on the lower edge of the door frame.

[0068] With the above solution, when the handle is rotated downwards, the upper and lower latch bars can extend upwards and downwards simultaneously, inserting into the fixing holes on the upper and lower edges of the door frame respectively, thus achieving a locked state. The design of the upper and lower latches allows for a more secure lock.

[0069] Furthermore, adopt the method shown in the appendix. Figure 10 As shown in the installation method, touching the rotating handle 1075 downwards locks the door, and touching the rotating handle 1075 upwards opens it. With this structure, the gravity received by the rotating handle 1075 during transportation keeps the double doors 103 in the closed state. During transportation bumps, the rotating handle 1075 is difficult to turn upwards to avoid loosening, further improving the stability of the manual door lock structure 107 and reducing the probability of goods spilling during transportation.

[0070] Based on the above embodiments, in another embodiment, reference is made to... Figure 11 A fixing hole 1076 is provided on the rotary handle 1075. The manual door lock structure 107 also includes a plastic buckle 1077, which is used to pass through the fixing hole 1076 to fix the rotary handle 1075 to the double door 103.

[0071] The plastic buckle 1077 creates a one-time sealed space for the carriage using the manual door lock structure 107, ensuring stable locking and sealing against lead. This facilitates confirmation that the goods inside the carriage have been disinfected or treated, and allows for easy tracking of the goods' status when the user or responsible person changes.

[0072] Correspondingly, a label can be set on the plastic buckle 1077 to allow for the filling in of relevant information.

[0073] In one embodiment, one of the doors has a protruding edge that can cover the edge of the other door when the double door 103 is closed.

[0074] This design allows for one-handed opening and closing of the door, and further enhances the sealing performance of the double doors 103.

[0075] In one embodiment of this application, a caster wheel orientation device 108 may be provided in any transfer device (such as a transfer vehicle 10 or a flatbed trolley 11) where any caster is a swivel wheel 110.

[0076] This application exemplifies, for example, the transfer vehicle 10, such as Figure 12 As shown, the universal wheel orientation device 108 may include a foot pedal 1081, a transmission rod 1082 fixedly connected to the foot pedal 1081, two symmetrically distributed fixing parts 1083, two symmetrically distributed locking rods 1084, and two symmetrically distributed plate-shaped locking structures 1085. The two locking rods 1084 are located at both ends of the transmission rod 1082 and are perpendicular to the transmission rod 1082 respectively. The transmission rod 1082 is rotatably connected to the bottom of the transfer vehicle 10 through the two fixing parts 1083. The universal wheel 110 includes a universal wheel frame 1101 and a universal wheel tire 1102.

[0077] When subjected to force, the foot pedal 1081 drives the transmission rod 1082 to rotate, which in turn drives the two locking rods 1084, causing the two locking rods 1084 to swing the plate-shaped locking structures 1085 on both sides. The plate-shaped locking structures 1085 cooperate with the universal wheel frame 1101 of the universal wheel 110 to restrict the universal wheel from turning on the horizontal plane.

[0078] In the above embodiment, the locking rod 1084 can directly drive the plate-shaped locking structure 1085 to lock the rotation of the caster wheel in the horizontal direction.

[0079] Based on this, in another embodiment, such as Figure 13 As shown, the locking rod 1084 is equipped with a locking spring 10841, and one end of the plate-shaped locking structure 1085 is a U-shaped structure 10851, and the other end is used to cooperate with the universal wheel frame 1101. The middle part of the plate-shaped locking structure 1085 is rotatably connected to the bottom of the carriage. The locking rod 1084 is used to lock into any corner of the U-shaped structure 10851 under the action of the locking spring 10841.

[0080] By enriching the structure of the locking rod 1084 and the plate-shaped locking structure 1085, and through the elastic force of the locking spring 10841, the locking rod 1084 can be engaged into one of the two corners of the U-shaped structure 10851, as shown in the attached figure. Figure 13 As shown, different corners can be engaged to maintain different states, thereby enabling the swivel wheel to be steerable or non-steerable without the need to continuously step on the foot pedal 1081, thus improving the ease of use of the device.

[0081] like Figure 14As shown, in a second aspect, this application also provides a connection method applied to the storage and transportation system 1 of any embodiment. A shelf 13 containing items to be transported is placed on a floor-mounted bracket 12. The connection method may include:

[0082] S101. Move the flatbed trolley 11 close to the shelf 13 so that the second track is aligned with the third track;

[0083] S102, push the shelf 13 onto the flatbed trolley 11;

[0084] S103. Open the carriage and bring the flatbed trolley 11 carrying the shelf 13 close to the carriage so that the first track and the second track are aligned.

[0085] S104, Push shelf 13 into the carriage;

[0086] S105, Close the carriage.

[0087] Any of the above steps can be broken down into multiple steps, or the multiple steps can be combined into one step, and this application does not impose any restrictions on this.

[0088] By applying the connection method of the storage and transportation system 1 provided by the first party of this application, the transfer of goods between different storage and transportation facilities can be realized quickly.
