Description

Technical Field

[0001] The present invention relates to the field of loading and unloading of goods in cold chain materials, and particularly to a mobile transfer platform for cold chain logistics. Background Art

[0002] A plurality of loading and unloading ports (with door seals at the loading and unloading ports) are usually installed at intervals on the outer wall of a cold storage for cooperation with cold chain transport vehicles, so as to meet the simultaneous loading and unloading requirements of multiple refrigerated trucks and improve operation efficiency. When loading and unloading goods, the body of the refrigerated truck is perpendicular to the outer wall of the cold storage, and its tail extends into the loading and unloading port to ensure loading and unloading efficiency and reduce cold loss. At present, the lengths of cold chain transport vehicles on the market vary from 4 to 22 meters. Although the use proportion of large refrigerated trucks is relatively low, the loading and unloading site still needs to meet the loading and unloading requirements of large refrigerated trucks. The existing loading and unloading method requires the depth of the loading and unloading area outside the cold storage area to reach about 50 meters, and the loading and unloading area is relatively large, resulting in waste of land. In addition, the operation sites of some old cold storages are very limited and cannot meet the loading and unloading operations of refrigerated trucks. Summary of the Invention

[0003] In view of this, the present invention provides a mobile transfer platform for cold chain logistics, which can be flexibly adjusted between the loading and unloading ports of the cold storage and can also significantly improve the utilization rate of the loading and unloading area.

[0004] To achieve the above object, the present invention adopts the following technical solutions: The mobile transfer platform for cold chain logistics of the present invention includes an X-direction guide rail parallel to the outer wall of the cold storage, a transplanting device moving along the X-direction guide rail, a buffer room arranged on the transplanting device, and a pressing and sealing structure arranged on the side wall of the buffer room. The buffer room is a hollow structure surrounded by a top plate, a bottom plate, a first side plate and a second side plate. The bottom plate is horizontally installed on the transplanting device. The buffer room has a first docking port for docking with the loading and unloading port and a second docking port for docking with the refrigerated truck. The first docking port is a rectangular port parallel to the outer wall of the cold storage. The included angle between the second docking port and the outer wall of the cold storage is an acute angle, so that the refrigerated truck is parked obliquely relative to the cold storage. An outer door opening is provided at the edge of the second docking port. The pressing and sealing structure includes a plurality of electric push rods arranged at intervals on the outer door opening and rubber sealing heads arranged on the electric push rods. The rubber sealing heads abut against the tail of the refrigerated truck.

[0005] The beneficial effects are as follows: the mobile transfer platform of the present invention can be rotated to a non-loading and unloading port when not in use, ensuring normal docking and loading and unloading operations at the loading and unloading port and improving utilization rate; in addition, it can be moved to the loading and unloading port when in use, so that the loading and unloading port of the hall and the rear of the vehicle can be sealed as much as possible to reduce cooling loss; furthermore, the buffer room of the present invention allows the vehicle to dock at an angle relative to the outer wall of the warehouse, reducing the requirements for the depth of the loading and unloading area. It is not only suitable for the renovation of existing cold storage, but also for the construction of new cold storage, with high land utilization rate.

[0006] Preferably, the transplanting device includes an X-axis running mechanism that travels along the X-axis guide rails and a Y-axis moving mechanism disposed on the X-axis running mechanism, and the buffer room is disposed on the Y-axis moving mechanism. More preferably, the X-axis running mechanism includes an X-axis motor reducer connected to a running frame and an X-axis motor reducer disposed on the running frame, the X-axis motor reducer being in transmission connection with the driving wheels of the running frame, enabling the running frame to move in the X-axis along the X-axis guide rails; the Y-axis moving mechanism includes a horizontally disposed mounting frame and a Y-axis motor reducer connected to the running wheels of the mounting frame, the Y-axis motor reducer driving the mounting frame to move along the Y-axis guide rails on the running frame. During actual operation, the X-axis running mechanism can drive the buffer room to move back and forth in a straight line along the X-axis guide rails, thereby enabling it to freely switch between the loading and unloading port and the non-loading and unloading position. When in use, it can be moved to the loading and unloading port, and when not in use, it can be moved to other positions, thereby improving the utilization rate of the loading and unloading port. In addition, the buffer room of the present invention can be adjusted in the Y axis to ensure that the buffer room can enter the door seal of the loading and unloading port, thereby ensuring the best possible sealing performance.

[0007] Preferably, the top plate, bottom plate, first side plate and second side plate of the buffer room are all insulation plates to reduce cold loss; the bottom plate and the mounting frame are both trapezoidal structures (more preferably right-angled trapezoidal structures), and the vehicle can be aligned with the hypotenuse of the bottom plate, so that the vehicle can be parked at an angle relative to the cold storage, thereby improving the land utilization rate of the loading and unloading area and meeting the parking needs of large vehicles; a polyurethane insulation layer is provided between the bottom plate and the mounting frame to reduce cold loss.

[0008] Preferably, each of the movable ends of the electric push rods is provided with a connector, and the rubber sealing head is provided on the connector; the compression sealing structure also includes an aerogel felt fixedly connected to the outer door opening, and the outer end of the aerogel felt is fixedly connected to the connector of the electric push rod; a connecting tail plate is also hinged on the bottom plate of the buffer room, and an electro-hydraulic push rod is provided at the bottom of the mounting frame, and the connecting tail plate is connected to the movable end of the electro-hydraulic push rod. The beneficial effect is that the present invention can place the connecting tail plate on the vehicle floor of the vehicle, and the aerogel felt is arranged along the circumference of the outer door opening (except the bottom of the outer door opening), which is combined with the connecting tail plate to ensure the sealing performance between the buffer room and the vehicle and minimize losses. In addition, the electric push rod realizes the expansion and stacking of the aerogel felt, which can meet the sealing connection requirements of different vehicles and buffer rooms.

[0009] Preferably, the mobile transfer platform further includes a control system, which includes a controller, an alarm unit, an X-direction monitoring unit for monitoring the traveling position of the X-direction traveling mechanism, a Y-direction monitoring unit for monitoring the position of the Y-direction moving mechanism, a tail plate monitoring unit for monitoring the position of the connecting tail plate, and a push rod monitoring unit for monitoring the electric push rod. The signal output ends of the X-direction monitoring unit, the Y-direction monitoring unit, the tail plate monitoring unit, and the push rod monitoring unit are connected to the signal input end of the controller, and the alarm signal output end of the controller is connected to the alarm signal input end of the alarm unit, so as to realize the monitoring of the positions of the X-direction traveling mechanism, the Y-direction moving mechanism, the electric push rod, and the connecting tail plate, and improve the safety.

[0010] Compared with the prior art, the advantages of the present invention are as follows: When the mobile transfer platform of the present invention is not in use, it can be rotated to a non-loading and unloading port to ensure the normal docking and loading and unloading operations at this loading and unloading port, improving the utilization rate; in addition, when in use, it can be moved to the loading and unloading port, and the loading and unloading port of the corridor and the vehicle tail can be sealed and connected as much as possible to avoid heat and cold exchange and reduce cold loss; furthermore, the buffer room of the present invention enables the vehicle to be tilted and parked relative to the outer wall of the warehouse, reducing the requirement for the depth of the loading and unloading area, meeting the docking and loading and unloading needs of large vehicles in front of cold storages with a shallower depth, and for newly built cold storage areas, effectively saving the area of the loading and unloading area in front of the cold storage and improving the land utilization rate of the cold storage area.

[0019] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation manners and specific operation procedures are given. However, the protection scope of the present invention is not limited to the following embodiments.

[0020] It should be noted that in the description of the present invention, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0021] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected" and "coupled" may be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0022] As Figures 1-5 shown, the present invention provides a mobile transfer platform for cold chain logistics, which includes an X-direction guide rail 1 parallel to the outer wall of the cold storage, a transplanting device moving along the X-direction guide rail 1, a buffer room 4 arranged on the transplanting device, and a pressing and sealing structure arranged on the side wall of the buffer room 4; Two installation grooves are dug on the ground outside the outer wall of the cold storage, and an X-direction guide rail 1 is laid in each installation groove to realize the concealed laying of the X-direction guide rail 1. On the one hand, it can protect the X-direction guide rail 1 from collision, and on the other hand, it can avoid the X-direction guide rail 1 protruding from the ground and affecting the docking of vehicles. For details, see Figure 1 ; The transplanting device includes an X-direction walking mechanism 2 moving along the X-direction guide rail 1 and a Y-direction moving mechanism 3 arranged on the X-direction walking mechanism 2, and the buffer room 4 is arranged on the Y-direction moving mechanism 3. During operation, the X-direction walking mechanism 2 can drive the buffer room 4 to move back and forth linearly along the X-direction through the Y-direction moving mechanism 3, so that the present invention can move between the loading and unloading ports and the non-loading and unloading ports. It can be moved to the loading and unloading port during use and moved to the non-loading and unloading position when not in use, improving the utilization rate of the loading and unloading port and thus improving the cold storage's inbound and outbound efficiency; The buffer room 4 is a hollow structure surrounded by a top plate, a bottom plate 4.1, a first side plate and a second side plate. The bottom plate 4.1 is horizontally installed on the Y-direction moving mechanism 3. The buffer room 4 has a first docking port for docking with the loading and unloading port and a second docking port for docking with the refrigerated truck. The first docking port is a rectangular port parallel to the outer wall of the cold storage. Among them, during actual installation, the height of the top plate of the buffer room 4 is lower than the door seal of the loading and unloading port, ensuring that the buffer room 4 can be aligned with the loading and unloading port, and the door curtain at the loading and unloading port can be placed on the top plate, minimizing the cold loss as much as possible. The included angle between the second docking port and the outer wall of the cold storage is an acute angle, enabling the refrigerated truck to dock obliquely relative to the cold storage, reducing the requirement for the depth of the loading and unloading site, meeting the docking needs of large vehicles in cold storages with small loading and unloading sites, applicable to both existing cold storages and newly built cold storages, improving land utilization rate, and having important promotion value. At the edge of the second docking port, there is an outer door opening 4.2 (its height is slightly lower than the top plate of the buffer room 4). The outer door opening 4.2 is located outside the second docking port. The pressing and sealing structure includes a plurality of electric push rods 5.1 arranged at intervals on the outer door opening 4.2 (arranged at intervals along the two side walls and the top wall of the outer door opening 4.2) and rubber sealing heads 5.2 arranged on the electric push rods 5.1. After the electric push rods 5.1 extend, the rubber sealing heads 5.2 can abut against the tail of the vehicle, pressing the rear compartment of the vehicle.

[0023] When not in use, the mobile transfer platform of the present invention can be rotated to a position other than the loading and unloading port, ensuring the normal docking and loading and unloading operations at this loading and unloading port and improving the utilization rate. In addition, when in use, it can be moved to the loading and unloading port, enabling the loading and unloading port of the corridor and the tail of the vehicle to be sealed and connected as much as possible, reducing cold loss. Moreover, the buffer room 4 of the present invention enables the vehicle to dock obliquely relative to the outer wall of the warehouse, reducing the requirement for the depth of the loading and unloading area, being applicable not only to the renovation of existing cold storages but also to newly built cold storages, and having a high land utilization rate.

[0024] During actual installation, the X-direction walking mechanism 2 includes a walking frame 2.1 and an X-direction motor reducer 2.2 arranged on the walking frame 2.1. The walking frame 2.1 includes a moving cross beam 2.1a arranged in the X direction and a connecting beam 2.1b connecting the two moving cross beams 2.1a. A plurality of pairs of driving wheels 2.3 are installed at the bottom of the two moving cross beams 2.1a, and each pair of driving wheels 2.3 is connected by a wheel axle. The X-direction motor reducer 2.2 can be connected to one of the driving wheels 2.3 (of course, during actual installation, the X-direction motor reducer 2.2 can be one set, or two sets or more than two sets to meet the walking requirements), and the X-direction motor reducer can drive the walking frame 2.1 to move back and forth in a straight line in the X direction to meet the moving requirements of the buffer room 4 in the Y direction. For details, see Figure 1 and Figure 2 。

[0025] During actual installation, in combination with Figures 5-6As can be seen, the Y-axis moving mechanism 3 includes a horizontally arranged mounting frame and a Y-axis motor reducer 3.1 connected to the mounting frame's running wheels 3.2. The running frame 2.1 is provided with a Y-axis guide rail, and the mounting frame has running wheels 3.2 that travel along the Y-axis guide rail. The Y-axis motor reducer 3.1 is in driving connection with one of the running wheels 3.2, and the Y-axis motor reducer 3.1 drives the mounting frame along the Y-axis guide rail on the running frame 2.1. During operation, the X-axis running mechanism 2 can drive the buffer room 4 to move back and forth in a straight line along the X-axis guide rail 1, thereby achieving free switching between the loading and unloading port and the non-loading and unloading position. When in use, it can be moved to the loading and unloading port, and when not in use, it can be moved to other positions, thereby improving the utilization rate of the loading and unloading port. In addition, the buffer room 4 of the present invention can be adjusted in the Y axis to ensure a reliable connection between the buffer room 4 and the loading and unloading port.

[0026] During actual installation, the mounting frame F has a double-layer structure. The upper and lower layers each include a Y-direction beam 3.3 corresponding to the Y-direction guide rail, a connecting crossbeam 3.4 for connecting the Y-direction beam 3.3, and a connecting oblique beam 3.5, so that the mounting frame has a trapezoidal structure as a whole. The upper and lower layers are connected by vertical beams 3.6. Figures 5-6 During actual processing, the top plate, bottom plate 4.1, first side plate and second side plate of the buffer room 4 are all made of insulation plates to reduce cooling loss; the traveling frame 2.1, bottom plate 4.1 and mounting frame are all trapezoidal structures (more preferably right-angled trapezoidal structures), and vehicles can align with the hypotenuse of the bottom plate 4.1, allowing the vehicles to dock at an angle relative to the cold storage, improving the land utilization rate of the loading and unloading area and meeting the docking needs of large vehicles; a polyurethane insulation layer is provided between the bottom plate 4.1 and the mounting frame to reduce cooling loss.

[0027] During actual installation, a connector 5.3 (which can be made of lightweight C-shaped steel or plastic) is provided on the movable end of each electric push rod 5.1, and a rubber sealing head 5.2 is provided on the connector 5.3; the compression sealing structure also includes an aerogel felt 5.4 fixedly connected to the outer door opening 4.2, and the outer end of the aerogel felt 5.4 is fixedly connected to the connector 5.3 of each electric push rod 5.1. When the electric push rods 5.1 are pushed out simultaneously, the aerogel felt 5.4 can be unfolded, and when the electric push rods 5.1 are retracted, the aerogel felt 5.4 can be stacked together, so as to adjust the distance between the buffer room 4 and the vehicle and minimize the cooling loss. For details, see Figures 3-4 ; Combine Figures 5-7 It can be seen that a connecting tail plate 4.3 is hingedly connected to the bottom plate 4.1 of the buffer room 4. An electro-hydraulic push rod 6 is provided at the bottom of the bottom plate 4.1. The connecting tail plate 4.3 is connected to the movable end of the electro-hydraulic push rod 6, so that the connecting tail plate 4.3 can be placed on the bottom plate of the vehicle compartment, which is convenient for loading and unloading and can also reduce the influence of outside air.

[0028] Combine Figure 8It can be seen that the mobile transfer platform of the present invention further includes a control system, which includes a controller, an alarm unit, an X-direction monitoring unit for monitoring the traveling position of the X-direction traveling mechanism 2, a Y-direction monitoring unit for monitoring the position of the Y-direction moving mechanism 3, a tail plate monitoring unit for monitoring the position of the connecting tail plate 4.3, and a push rod monitoring unit for monitoring the push rod of the electric push rod 5.1. The signal output ends of the X-direction monitoring unit, the Y-direction monitoring unit, the tail plate monitoring unit, and the push rod monitoring unit are connected to the signal input end of the controller, and the alarm signal output end of the controller is connected to the alarm signal input end of the alarm unit, so as to realize the monitoring of the positions of the X-direction traveling mechanism 2, the Y-direction moving mechanism 3, the electric push rod 5.1, and the connecting tail plate 4.3, improving safety; The X-direction monitoring unit includes two X-direction limit switches, which can limit the X-direction position of the present invention to ensure reciprocation between the loading and unloading positions and the non-loading and unloading positions. Among them, when the X-direction limit switch is triggered, the X-direction motor reducer 2.2 stops working; similarly, the Y-direction monitoring unit includes two Y-direction limit switches, which can limit the left and right positions of the buffer room 4. When the Y-direction limit switch is triggered, the Y-direction motor reducer 3.1 stops working; the tail plate monitoring unit includes an extended limit switch and a retracted limit switch. The controller can adjust the state of the connecting tail plate 4.3 by controlling the duration, so that it can rotate relative to the bottom plate 4.1; the telescopic limit switch and the retracted limit switch are used to limit the electro-hydraulic push rod 6. When it runs to the limit position, the limit switch transmits a signal to the controller. After the controller analyzes it, it transmits it to the alarm unit for alarm, and the electro-hydraulic push rod 6 stops moving; similarly, the push rod monitoring unit includes two push rod limit switches (one for extension limit and one for retraction limit), which can limit the extension and retraction of the electric push rod 5.1 to avoid exceeding its designed stroke and protect the electric push rod 5.1; The control input ends of the X-direction motor reducer, the Y-direction motor reducer, the electric push rod, and the electro-hydraulic push rod are connected to the control output end of the controller to achieve automatic control. Of course, during actual installation, the X-direction motor reducer, the Y-direction motor reducer, the electric push rod, and the electro-hydraulic push rod are equipped with manual buttons for convenient manual start and stop.

[0029] It should be noted that the above-mentioned controller can be a general-purpose processor, a special-purpose processor, a conventional processor, a digital signal processor (DSP), multiple microprocessors, one or more microprocessors associated with the DSP core, a controller, a microcontroller, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) circuit, any other type of integrated circuit (IC), and a state machine. It can also be a PLC controller, or an industrial control computer with computer attributes and characteristics. Further, the controller of the present invention can also be provided with a wireless communication module to realize connection with a remote terminal and receive control instructions from the remote terminal.

[0030] The specific working process of the present invention is as follows: When not in use, the present invention is moved to a non-loading and unloading position, thus avoiding the loading and unloading opening to meet the docking and loading / unloading requirements of other vehicles at this loading and unloading opening, and improving the utilization rate of this loading and unloading position; When a large vehicle comes, the present invention is moved to the loading and unloading opening corresponding to the large vehicle until the first docking port of the buffer room 4 is directly opposite to the loading and unloading opening; Then start the Y-direction motor reducer 3.1 to drive the buffer room 4 to make Y-direction adjustment (i.e., Figure 1 the left-right direction in

[0031] ); Use the electro-hydraulic push rod 6 to adjust the connecting tail plate 4.3 so that it rotates upward with the side edge of the bottom plate 4.1 as the reference (i.e., the connecting tail plate 4.3 tilts upward), align the tail of the large vehicle with the external opening and reverse the vehicle. After the large vehicle arrives, lower the connecting tail plate 4.3 so that it is placed on the carriage floor; Then start the electric push rod 5.1. The electric push rod 5.1 extends, and the rubber sealing head 5.2 contacts the carriage and presses tightly; The aerogel felt 5.4 can be unfolded to the carriage together with the electric push rod 5.1 to minimize the heat and cold exchange as much as possible. Finally, it should be emphasized that the above description is only the preferred embodiment of the present invention and is not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions described in the foregoing embodiments without creative labor, or make equivalent replacements for some of the technical features. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
