DETAILED DESCRIPTION

[0034] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

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

[0036] like Figure 1As shown, the storage and transportation system 1 of the preferred embodiment of the present invention comprises a transfer vehicle 10, a flatbed cart 11, a floor bracket 12 and a shelf 13; casters are installed at the bottom of the transfer vehicle 10, and at least two first guide rails 102 are installed on the inner bottom surface of the compartment of the transfer vehicle 10; casters are installed at the bottom of the cart bottom plate 111 of the flatbed cart 11, and at least two second guide rails 112 are installed on the cart bottom plate 111; the support foot 121 of the floor bracket 12 is fixed below the bracket bottom plate 122, and the upper part of the bracket bottom plate 122 is provided with a support foot 121 of the floor bracket 12. At least two third guide rails 123; the size of the shelf 13 is not larger than the size of the carriage, and at least two rows of pulleys 131 are installed at the bottom of the shelf 13; wherein, the arrangement spacing of at least two first guide rails 102, the arrangement spacing of at least two second guide rails 112, and the arrangement spacing of at least two third guide rails 123 are equal to the arrangement spacing of at least two rows of pulleys 131, and the mounting surfaces of the first guide rail 102, the second guide rail 112 and the third guide rail 123 are at the same height from the ground, so that the pulley 131 can slide on any guide rail.

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

[0038] Through the above solution, there is no need to manually move goods one by one to different storage and transportation equipment. While improving efficiency, the risk of damage to goods is reduced due to the reduction in the number of moves. Its application in medical storage and transportation can reduce the probability of broken packages and contamination, and has good application prospects.

[0039] Since the shelves 13 are directly placed on the guide rails, there is a certain risk of sliding of the shelves 13. Therefore, the present application provides a series of structures to reduce the risk of sliding and simplify the operation steps.

[0040] In one embodiment, if Figure 2 As shown, a first thrust member 124 protruding from the third guide rail 123 is fixed to 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 under 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 limit the sliding of the pulley 131 on the third guide rail 123. The existence of the first elastic member 126 enables the locking member to be opened or closed in time, thereby achieving the fixation or movement of the shelf 13, and completing the application conversion between the moving scenario and the transportation scenario.

[0042] It is understandable that the first thrust member 124 and the first locking member 125 can be used to resist 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 the present application does not impose any limitation.

[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, 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, and a second elastic member 106 is installed between the second locking member 105 and the car body; wherein, the second locking member 105 is used to extend out from the bottom of the car body under the elastic force of the second elastic member 106, and the second thrust member 104 and the second locking member 105 are used to limit the displacement of the shelf 13 in the car body.

[0045] The second thrust member 104 and the second locking member 105 cooperate with each other so that the shelf 13 can be locked in the compartment, and at the same time the second elastic member 106 enables the second locking member 105 to be compressed to achieve the transfer of the shelf 13 between different components.

[0046] In order to facilitate the operation of the transfer rack 13, the opening angle of the double-leaf door 103 can be 240 degrees to 270 degrees. The larger opening angle allows the compartment opening to be fully exposed, while there is still a certain standing space on both sides of the double-leaf door 103, which is convenient for auxiliary operation and the approaching flatbed cart 11 or the rack 13 in the transfer process.

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

[0048] In another embodiment, Figure 4As shown, the cart bottom plate 111 is also equipped with an operating rod 113 and a telescopic locking structure 114 located at the bottom, and one end of the second guide rail 112 is equipped with a third thrust piece 115 higher than the second guide rail 112; the middle part of the operating rod 113 is rotatably connected to the bottom plate, and the operating rod 113 is in abutment with the telescopic locking structure 114, and when one end of the operating rod 113 is rotated by force, the telescopic locking structure 114 is pushed to extend and retract; when the telescopic locking structure 114 is extended, the telescopic locking structure 114 and the third thrust piece 115 limit the displacement of the shelf 13 on the second guide rail 112.

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

[0050] Exemplarily, the telescopic locking structure 114 may include a push rod on the operating rod 113, a locking member capable of contacting the push rod, and an elastic member directly mounted on the locking member and the cart bottom plate 111. When the operating rod 113 rotates in the positive direction, the push rod and the locking member are separated, and the locking member extends from the cart bottom plate 111 under the elastic force of the elastic member; when the operating rod 113 rotates in the reverse direction, the push rod contacts the locking member and pushes the locking member to overcome the elastic force of the elastic member so that the locking member is hidden in the cart bottom plate 111.

[0051] In the exemplary drawings of the present application, the positive direction is clockwise, and the negative direction is counterclockwise. The positive and negative directions may also vary according to the actual installation position.

[0052] In one embodiment of the present application, a protruding structure 132 can be provided at the bottom of the shelf 13 to reduce the length requirement 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 contact the shelf 13 through the protruding structure 132 to complete the locking.

[0053] In one embodiment of the present application, Figure 5 As shown, the other end of the operating rod 113 is also provided with a toggle rod 1131. When different storage and transportation equipment are close, the toggle rod 1131 plays different roles:

[0054] like Figure 6 As shown, when the flatbed trolley 11 and the floor bracket 12 are close to each other, one end of the operating rod 113 is rotated under force, and the toggle rod 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 bottom 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 and the transfer vehicle 10 are close to each other, one end of the operating rod 113 is rotated under force, and the toggle rod 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 vehicle compartment, so that the shelf 13 located on the flatbed trolley 11 can enter the vehicle compartment.

[0056] Through the above scheme, when the flatbed cart 11 approaches the floor bracket 12, the personnel can simultaneously open or close the telescopic locking structure 114 on the flatbed cart 11 and the first thrust piece 124 on the floor bracket 12 through the operating rod 113. Therefore, when it is necessary to transfer the shelf 13 between the flatbed cart 11 and the transfer vehicle 10, the locking structure of the two storage and transportation equipment can be opened by operating once, and then the shelf 13 can be pushed in along the guide rail. The personnel do not need to move, bend over, etc., and can operate the operating rod 113 again on the spot to complete the locking after the transfer, which greatly saves the steps of transfer and reduces the number of personnel required. At the same time, one operating rod 113 operates two storage and transportation equipment, and there is no need to install the operating rod 113 on each storage and transportation equipment, which saves costs.

[0057] It can be understood that in any embodiment of the present application, the elastic member, the first elastic member 126, and the second elastic member 106 can be elastic devices that provide pressure (such as torsion springs, pressure springs), or elastic devices that provide tension (such as tension springs, rubber bands). By appropriately changing the installation structure of the elastic device, the solution of the present application can be applied to elastic devices of different forms and specifications. The adaptive adjustments that technical personnel in this field can make based on the content disclosed in this application should also fall within the protection scope of this application.

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

[0059] In another embodiment, elastic devices of the same form and specification may also be used.

[0060] In one embodiment of the present application, Figure 8 As shown, a push handle 116 is installed on the side of the cart bottom plate 111; the end of the operating rod 113 that is subjected to force is a continuous fold line structure 1132, and the continuous fold line structure 1132 extends the end of the operating rod 113 that is subjected to force to the push handle 116 of the flatbed cart 11.

[0061] By designing the continuous fold line structure 1132, the operating rod 113 is extended to a position close to the push handle 116, so that pushing and pulling the operating rod 113 is more ergonomic, and the operating rod 113 can be pushed and pulled without bending over. It is far away from the ground, making operation and disinfection easier.

[0062] At the same time, the extension of the operating rod 113 increases the force arm. According to the torque formula, a longer force arm makes the force required to be applied to the operating rod 113 smaller under the same torque requirement. Therefore, the use of the continuous fold line structure 1132 to extend the operating rod 113 to a position close to the push handle 116 also plays a role in saving effort.

[0063] In one embodiment, if Figure 9a and Figure 9b As shown, a brake structure 117 is installed near the caster on the cart bottom plate 111, and the brake structure 117 includes a foot pedal 1171, a transmission shaft 1172, a fixing ring 1173, two guide grooves, two brake plates 1175 and two brake rods 1174. The caster of the flatbed cart 11 includes a wheel frame 1091 and a tire 1092; the fixing ring 1173 is fixed to the bottom of the flatbed cart 11, the transmission shaft 1172 is rotatably connected to the fixing ring 1173, and two radial flanges 11721 are respectively provided at the two ends of the transmission shaft 1172. The foot pedal 1171 is fixedly connected to the transmission shaft In the middle part of 1172, two guide grooves are fixedly connected to the casters of the two flatbed carts 11 respectively, and the installation spacing of the two guide grooves is equal to the wheelbase of the casters of the two flatbed carts 11. The two guide grooves are placed in the vertical direction, and the two brake plates 1175 are rotatably connected to the two wheel frames 1091 respectively, and one end of the brake plate 1175 is located on the movement path of the brake rod 1174; after the foot pedal 1171 is subjected to force, it drives the radial flange 11721 to rotate, so that the brake rod 1174 presses one end of the brake plate 1175 until the brake plate 1175 rotates to contact with the tire 1092.

[0064] Through the above scheme, when the foot pedal 1171 is stepped on, the two radial flanges 11721 on the transmission shaft 1172 can simultaneously drive the two brake rods 1174 to move downward, so that the two brake plates 1175 respectively clamp the two casters 109, thereby achieving simultaneous braking of the casters 109 on both sides, and effective braking can also be achieved when fully loaded. The braking of the two brake rods 1174 and the two brake plates 1175 prevents the casters 109 from slipping after braking.

[0065] At the same time, a foot pedal 1171 is used for one-touch braking, which makes braking easier and convenient to operate during pushing.

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

[0067] In one embodiment of the present application, a manual door lock structure 107 may be installed at the door gap of one of the two doors 103. Fig.10As shown, the manual door lock structure 107 may include a guide shell 1071, a turntable 1072, an upper door latch rod 1073, a lower door latch rod 1074, and a rotating handle 1075. The guide shell 1071 is provided with a guide groove for the upper door latch rod 1073 and the lower door latch rod 1074 to move up and down. The turntable 1072 is rotatably connected to the guide shell 1071. The bottom of the upper door latch rod 1073 and the top of the lower door latch rod 1074 are rotatably connected to two holes symmetrically distributed on the turntable 1072, respectively. One end of the rotating handle 1075 is fixedly connected to the turntable 1072; so that when the rotating handle 1075 is forced to swing downward, it drives the turntable 1072 to rotate, thereby driving the upper door latch rod 1073 to insert upward into the fixed hole on the upper edge of the door frame, and driving the lower door latch rod 1074 to insert downward into the fixed hole on the lower edge of the door frame.

[0068] Through the above solution, when the handle is rotated downward, the upper and lower door latch rods can extend upward and downward at the same time, and are respectively inserted into the fixing holes on the upper and lower edges of the door frame to achieve a locked state. The design of the upper and lower door latches can achieve a more secure lock.

[0069] Furthermore, the following Fig.10 In the installation mode shown, the rotating handle 1075 is locked by touching it downwards, and is opened by touching it upwards. When this structure is adopted, the gravity received by the rotating handle 1075 during transportation can keep the double-leaf door 103 in a closed state, and the rotating handle 1075 is difficult to rotate upwards to become loose during transportation bumps, which further improves the stability of the manual door lock structure 107 and reduces the probability of spilling goods during transportation.

[0070] Based on the above embodiment, in another embodiment, reference Fig.11 A fixing hole 1076 is provided on the rotating handle 1075 , and the manual door lock structure 107 further includes a plastic buckle 1077 , which is used to pass through the fixing hole 1076 to fix the rotating handle 1075 on the double-leaf door 103 .

[0071] The manual door lock structure 107 forms a one-time closed space in the carriage through the plastic buckle 1077, which can not only ensure the stability of the lock, but also have the effect of sealing lead. It is convenient to determine whether the goods in the carriage have been disinfected or processed in some way, and it is convenient to track the status of the goods when the user or responsible person is changed.

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

[0073] In one embodiment, one of the doors has a convex edge that can cover the edge of the other door when the bi-directional doors 103 are closed.

[0074] By designing this structure, it is possible to open and close the door with one hand and the sealing performance of the double-leaf door 103 is further enhanced.

[0075] In one embodiment of the present application, a universal wheel orientation device 108 may be provided in a transport device (such as a transport vehicle 10 or a flatbed cart 11 ) in which any caster is a universal wheel 110 .

[0076] This application is illustrative, taking the transfer vehicle 10 as an example, Fig.12 As shown, the universal wheel orientation device 108 may include a pedal 1081, a transmission rod 1082 fixedly connected to the pedal 1081, two symmetrically distributed fixing members 1083, two symmetrically distributed clamping rods 1084, and two symmetrically distributed sheet-like locking structures 1085. The two clamping rods 1084 are arranged at both ends of the transmission rod 1082 and are respectively perpendicular to the transmission rod 1082. The transmission rod 1082 is rotatably connected to the bottom of the transfer vehicle 10 through two fixing members 1083. The universal wheel 110 includes a universal wheel frame 1101 and a universal wheel tire 1102.
