Description

Technical Field

[0001] The utility model relates to the field of logistics transportation, in particular to a fixed separation device for logistics. Background Art

[0002] In the modern logistics industry, logistics boxes, as a widely used cargo transportation and storage container, can integrate multiple fragmented packages, facilitate transportation and utilize the cargo space of the transport vehicle itself. However, they are large in size and heavy in weight, but are simply stacked in the cargo hold of the transport vehicle. During transportation, logistics boxes are prone to displacement or tipping over due to vehicle bumps, sudden braking and other operations, which may not only cause damage to the goods, but also cause safety accidents and bring economic losses.

[0003] Therefore, the logistics box needs to be temporarily fixed during transportation, which brings some challenges. Usually, the separation of logistics boxes relies on manual operation, which is not only inefficient, but also difficult to ensure the stability and reliability of separation due to the uncertainty of human factors. At the same time, the impact force during the separation process is often large, which may cause secondary damage to the logistics box or the goods inside, increasing logistics costs.

[0004] If the logistics boxes can be automatically separated, loaded and unloaded, the above-mentioned problems can be solved. While ensuring separation efficiency and safety, the design of low-cost fixed separation devices for logistics needs to be paid special attention.

[0005] Therefore, it is very necessary to develop a fixed separation device for logistics that can effectively fix the logistics box during transportation and prevent it from displacement or tipping over, and can quickly and automatically separate the logistics box, reduce manual operation, improve separation efficiency, and has a simple structure, low cost, and is easy to maintain and repair. Utility Model Content

[0006] The utility model aims to provide a fixed separation device for logistics, so as to solve the technical problem that in the prior art, logistics boxes are simply stacked in the cargo hold of a transport vehicle, which may easily lead to damage to the goods in the logistics boxes due to displacement or collision of the logistics boxes when the vehicle is bumpy or braked suddenly.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A fixed separation device for logistics, used for fixing and separating logistics boxes during transportation; the logistics boxes are used to be placed in a placement rack, and the placement rack is fixed on a placement platform through the fixed separation device;

[0009] The fixed separation device comprises a loading plate, a driving device and a clamping device are installed in the loading plate, and clamping device installation positions are respectively extended from both sides of the fixed separation device for installing the clamping device, and the clamping position is between the clamping device installation positions on both sides, and the placement frame can be clamped in the clamping position;

[0010] The clamping device is in transmission connection with the driving device, and the driving device can drive the clamping device to extend or retract from the mounting position of the clamping device to clamp or release the placement frame;

[0011] The fixing and separating device further comprises a guiding device, which is fixed to a side surface of the fixing and separating device and can be plugged into a side surface of a mounting frame.

[0012] The working principle of this solution is to collect the bulk logistics boxes into the placement rack, and realize the loading, transportation and unloading of the logistics boxes by fixing and separating the placement rack and the placement platform; this solution utilizes a clamping device, which can clamp the placement rack in the clamping position to achieve the fixation of the placement rack, and can prevent the placement rack from shifting or shaking significantly during transportation. The use of a guiding device can enable the placement rack to smoothly enter between the clamping devices during the fixation process, and it is not easy to be misplaced or offset, and it is not easy to cause the clamping force of the clamping device on the placement rack to be reduced, resulting in the placement rack being dislocated.

[0013] Preferably, the fixed separation device also includes an ejection device, which is sleeved on the outer periphery of the guide device, and the ejection device and the guide device can be simultaneously plugged into the side of the mounting frame; when the driving device drives the clamping device to extend and clamp the fixed separation device, the ejection device can be compressed and have elastic potential energy.

[0014] In this way, when releasing the placement frame, the driving device drives the clamping device to release the placement frame, and the ejection device releases elastic potential energy, which can apply thrust to the placement frame to make it pop out, thereby facilitating the unloading of the placement frame and reducing the difficulty of manual operation.

[0015] As one implementation of the driving device, the driving device includes a release slider, a first coupling lever, a second coupling lever, a first clamping arm, and a second clamping arm;

[0016] A slideway is fixed on the loading plate, and the release slider can be slidably connected to the slideway;

[0017] The first coupling lever and the second coupling lever are respectively connected to the release slider in a transmission manner, and when the release slider slides, the first coupling lever and the second coupling lever can be driven to rotate simultaneously;

[0018] The first clamping arm is transmission connected to one end of the first connecting lever away from the release slider, and the second clamping arm is transmission connected to one end of the second connecting lever away from the release slider; when the placement frame is fixed, the first clamping arm and the second clamping arm can be extended from their respective clamping device installation positions at the same time and abut against the outer side surface of the placement frame.

[0019] In this way, the driving device drives the release slider to slide, and then drives the first coupling lever and the second coupling lever to rotate, and then can drive the first clamping arm and the second clamping arm to extend from their respective clamping device installation positions at the same time, and abut against the outer side surface of the placement frame to achieve clamping and fixation of the placement frame. When releasing the placement frame, the release slider slides in the opposite direction, driving the first coupling lever and the second coupling lever to rotate in the opposite direction, and then can drive the first clamping arm and the second clamping arm to retract to their respective clamping device installation positions at the same time, thereby releasing the placement frame.

[0020] As one implementation manner of the guiding device, the guiding device is a sleeve rod, and one end of the sleeve rod is fixed to the outer side wall of the fixing and separating device.

[0021] As one implementation of the ejection device, the ejection device uses a compression spring, and the compression spring can be sleeved on the outer circumference of the guide device.

[0022] Preferably, the first connecting lever comprises a first long axis and a first short axis, the first long axis is rotatably connected to the first short axis; the first clamping arm is rotatably connected to the transmission end of the first short axis; at the same time, the first clamping arm is rotatably connected to the loading plate, and the first long axis is rotatably connected to the loading plate;

[0023] The second connecting lever includes a second long axis and a second short axis, the second long axis is rotatably connected to the second short axis; the second clamping arm is rotatably connected to the transmission end of the second short axis; at the same time, the second clamping arm is rotatably connected to the loading plate, and the second long axis is rotatably connected to the loading plate.

[0024] Specifically, in the initial state of preparing to fix the placement frame, the release slider is located at one end of the slideway close to the driving device, the first coupling lever and the second coupling lever are in a tightened state at this time, the horizontal angle between the first long axis and the first short axis, the second long axis and the second short axis is the smallest, and each clamping arm is in a tensioned state at this time; then the driving device drives the first long axis and the second long axis to rotate, thereby driving the first short axis and the second short axis to rotate, thereby driving the first clamping arm and the second clamping arm to extend and clamp the placement frame, and at the same time, the compression spring is compressed and has elastic potential energy; then, when releasing the placement frame, the driving device drives the first long axis and the second long axis to rotate in the opposite direction, thereby driving the first short axis and the second short axis to rotate in the opposite direction, the horizontal angle between the first long axis and the first short axis, the second long axis and the second short axis gradually increases, and gradually changes from a tensioned state to a relaxed state, thereby driving the first clamping arm and the second clamping arm to retract, and the fixing effect of each clamping arm on the placement frame is weakened. At the same time, each ejection compression spring releases elastic potential energy, so that the placement frame has a certain initial separation velocity, and the placement frame is ejected.

[0025] As one implementation of the driving device, the driving device includes a motor, which is in driving connection with the release slider; the driving device also includes a built-in power supply, which is electrically connected to the motor and is used to drive the motor to operate. This can facilitate the release and fixation of the placement frame during transportation without the need for an external power supply, and is suitable for scenarios where it is inconvenient to connect an external power supply.

[0026] As a preferred embodiment of the slide, the slide includes a first slide rail and a second slide rail arranged in parallel, the first slide rail and the second slide rail are both fixed on the loading plate, and the corresponding bottom of the release slider is provided with a first slide groove and a second slide groove, the inner circumferential dimension of the first slide groove matches the outer circumferential dimension of the first slide rail, and the inner circumferential dimension of the second slide groove matches the outer circumferential dimension of the second slide rail, so that the release slider can slide stably on the first slide rail and the second slide rail, and is not prone to position displacement.

[0027] Preferably, the fixing and separating device also includes a signal receiving device, which has a signal receiving module therein, and the signal receiving module is used to receive clamping, fixing or separation instructions from the placement platform. The signal receiving device is electrically connected to the built-in power supply to control the forward, reverse or stop rotation of the motor through the clamping, fixing or separation instructions from the placement platform.

[0028] During implementation, the placement platform sends out a signal, which is received by the signal receiving device. When the signal receiving device receives a separation instruction, the built-in power switch of the motor is turned on, and the motor is run in the forward direction, and the motor pushes the release slider to slide on the slide in the direction away from the motor; when the signal receiving device receives a clamping and fixing instruction, the built-in power switch of the motor is turned on, and the motor is run in the reverse direction, and the motor pushes the release slider to slide on the slide in the direction close to the motor, thereby clamping and fixing the placement frame.

[0029] Preferably, a first buffer compression spring sleeve rod and a second buffer compression spring sleeve rod are also fixed in the loading plate, and the first buffer compression spring sleeve rod and the second buffer compression spring sleeve rod are respectively sleeved with a first buffer compression spring and a second buffer compression spring, which are used to buffer the first long axis and the second long axis respectively; the extension direction of the first buffer compression spring and the second buffer compression spring is parallel to the rotation plane of the first long axis and the second long axis.

[0030] The first buffer compression spring and the second buffer compression spring are used to reduce the mechanical vibration generated at the moment when the first connecting shaft lever and the second connecting shaft lever start to swing and the swing and oscillation at the end of the swing, so as to ensure the smooth operation of the fixing and separating device.

[0031] During implementation, after each ejection compression spring releases its elastic potential energy, it will drive the vibration of each connecting lever inside the fixed separation device. Therefore, setting the first buffer compression spring and the second buffer compression spring can weaken the vibration amplitude of the long axis of each connecting lever, thereby weakening the mechanical vibration inside the fixed separation device and ensuring the stable operation of the placement platform.

[0032] The technical solution of the utility model has the following beneficial effects: the fixed separation device for logistics disclosed by the utility model has a simple structure, integrates various components, and can integrate multiple logistics boxes in the placement rack, so that the logistics boxes are safer and more convenient during transportation, and can realize the transportation of multiple logistics boxes at a time, which is beneficial to improving transportation efficiency and transportation quality. The utility model adopts mechanical transmission to perform guided clamping and release of the placement rack, which reduces the operating difficulty of the operator. It has the advantages of simple system, low cost, stable operation and easy maintenance. It can solve the technical problem that in the prior art, the logistics boxes are simply stacked in the cargo hold of the transport vehicle, which is prone to damage to the goods in the logistics boxes due to displacement or collision of the logistics boxes when the vehicle is bumpy or braked suddenly.

[0049] The working principle of this solution is to collect the bulk logistics boxes into the placement rack 900, and realize the loading, transportation and unloading of the logistics boxes by fixing and separating the placement rack 900 from the placement platform; this solution utilizes a clamping device, which can clamp the placement rack 900 in the clamping position to achieve the fixation of the placement rack 900, and can prevent the placement rack 900 from shifting or shaking significantly during transportation. The use of a guiding device can enable the placement rack 900 to smoothly enter between the clamping devices during the fixation process, and it is not easy to be misplaced or offset, and it is not easy to cause the clamping force of the clamping device on the placement rack 900 to be reduced, resulting in the placement rack 900 being dislocated.

[0051] In this way, when releasing the placement frame 900, the driving device drives the clamping device to release the placement frame 900, and the ejection device releases elastic potential energy, which can apply thrust to the placement frame 900 to make it pop out, thereby facilitating the unloading of the placement frame 900 and reducing the difficulty of manual operation.

[0053] In this way, the driving device drives the release slider 300 to slide, and then drives the first connecting lever 401 and the second connecting lever 402 to rotate, and then can drive the first clamping arm 601 and the second clamping arm 602 to extend from their respective clamping device installation positions at the same time, and abut against the outer side surface of the placement frame 900, so as to achieve clamping and fixing of the placement frame 900. When releasing the placement frame 900, the release slider 300 slides in the opposite direction, driving the first connecting lever 401 and the second connecting lever 402 to rotate in the opposite direction, and then can drive the first clamping arm 601 and the second clamping arm 602 to retract to their respective clamping device installation positions at the same time, thereby releasing the placement frame 900.

[0054] As one implementation of the guiding device, the guiding device is a sleeve rod, one end of which is fixed to the outer side wall of the fixing and separating device 100 .

[0055] As one implementation of the ejection device, the ejection device uses a compression spring, and the compression spring can be sleeved on the outer circumference of the guide device.

[0058] In this way, when clamping the placement frame 900, the first clamping arm 601 and the second clamping arm 602 are simultaneously extended from their respective clamping device installation positions and abut against the outer side surface of the placement frame 900 to achieve clamping and fixation of the placement frame 900. At the same time, they are compressed at the same time to store elastic potential energy. When releasing the placement frame 900, the first clamping arm 601 and the second clamping arm 602 are simultaneously retracted to their respective clamping device installation positions. At the same time, the first ejection compression spring 501 and the second ejection compression spring 502 simultaneously release elastic potential energy to eject the placement frame 900, thereby achieving separation of the placement frame 900 from the placement platform.

[0059] Specifically, the ends of the first ejection compression spring 501 and the second ejection compression spring 502 respectively have radial protrusion structures, and the radial protrusion structures can be interference-fitted with the first plug hole 902 and the second plug hole 903 respectively.

[0060] Preferably, the outer side of the other side of the fixing and separating device 100 opposite to the first compression spring sleeve rod 107 and the second compression spring sleeve rod 108 is respectively fixed with a first anchor nut 701 and a second anchor nut 702 for fixing the fixing and separating device 100 with the placing platform, so that the fixing and separating device 100 itself is more firmly secured.

[0061] As a preference, see Figure 2 and Figure 3 The first connecting lever 401 includes a first long axis 4011 and a first short axis 4012, and the first long axis 4011 is rotatably connected to the first short axis 4012; the first clamping arm 601 is rotatably connected to the transmission end of the first short axis 4012; at the same time, the first clamping arm 601 is rotatably connected to the loading plate 103, and the first long axis 4011 is rotatably connected to the loading plate 103;

At the same time, each ejection compression spring releases elastic potential energy, so that the placement frame 900 has a certain initial separation velocity, and the placement frame 900 is ejected.

[0064] Specifically, the ends of the first clamping arm 601 and the second clamping arm 602 respectively have buckles protruding toward each other, and the buckles can be used to clamp the placement frame 900 .

[0065] Specifically, the length of the first major axis 4011 is 4 to 6 times that of the first minor axis 4012 , and the length of the second major axis 4021 is 4 to 6 times that of the second minor axis 4022 .

[0070] As a preferred solution of the driving device, the driving device further includes a built-in power supply, which is electrically connected to the motor 200 and is used to drive the motor 200 to operate. This can facilitate the release and fixation of the placement frame 900 during transportation without an external power supply, and is suitable for scenarios where it is inconvenient to connect an external power supply.

The corresponding bottom of the release slider 300 is provided with a first slide groove 302 and a second slide groove 303. The inner circumference size of the first slide groove 302 matches the outer circumference size of the first slide rail 1041, and the inner circumference size of the second slide groove 303 matches the outer circumference size of the second slide rail 1042, so that the release slider 300 can stably slide on the first slide rail 1041 and the second slide rail 1042, and is not prone to position displacement.

[0072] For details, please refer to Figure 5 A blocking portion 1043 is fixed between the first slide rail 1041 and the second slide rail 1042 at one end away from the motor 200 , for preventing the release slider 300 from falling off the first slide rail 1041 and the second slide rail 1042 .

When the motor 200 is working, the external threaded rod 201 can rotate forward or reverse, thereby driving the release slider 300 to move forward or backward along the slideway 104.

[0074] Specifically, the motor 200 is fixed on the center line of the loading plate 103 .

[0075] As a preference, see Figure 3 and Figure 4 The release slider 300 includes a first transmission groove 304 and a second transmission groove 305. A first transmission block 4013 is fixed on the first long axis 4011; a second transmission block 4023 is fixed on the second long axis 4021. The first transmission block 4013 is placed in the first transmission groove 304, and the second transmission block 4023 is placed in the second transmission groove 305 to realize force transmission.

[0076] As a preference, see Figure 3 The fixing and separating device 100 also includes a signal receiving device 101, which has a signal receiving module. The signal receiving module is used to receive a clamping or separation instruction from the placement platform. The signal receiving device 101 is electrically connected to the built-in power supply to control the motor 200 to run forward, reverse or stop through the clamping or separation instruction from the placement platform.

[0077] During implementation, the placement platform sends out a signal, which is received by the signal receiving device 101. When the signal receiving device 101 receives a separation instruction, the built-in power switch of the motor 200 is turned on, and the motor 200 is run in the forward direction. The motor 200 pushes the release slider 300 to slide on the slide 104 in the direction away from the motor 200; when the signal receiving device 101 receives a clamping and fixing instruction, the built-in power switch of the motor 200 is turned on, and the motor 200 is run in the reverse direction. The motor 200 pushes the release slider 300 to slide on the slide 104 in the direction close to the motor 200, clamping and fixing the placement frame 900.

[0078] For details, please refer to Figure 1 and Figure 3 The fixing and separating device 100 further includes a cover body 102, and the cover body 102 is used to protect various components installed in the loading plate 103, and the cover body 102 is detachably connected to the loading plate 103 by bolts.

[0079] Specifically, six splicing sockets are fixed on the loading plate 103, which are symmetrically distributed on the left and right, and the positions correspond to the positions on the cover body 102 for inserting rivets, and are used to fix the overall shell. The simplicity of the overall shell ensures the rapid assembly of the fixed separation device 100.

[0080] As a preference, see Figure 3 and Figure 5 A first buffer compression spring sleeve rod 105 and a second buffer compression spring sleeve rod 106 are also fixed in the loading plate 103, and the first buffer compression spring sleeve rod 105 and the second buffer compression spring sleeve rod 106 are respectively sleeved with a first buffer compression spring 801 and a second buffer compression spring 802, which are used to buffer the first long axis 4011 and the second long axis 4021 respectively; the extension direction of the first buffer compression spring 801 and the second buffer compression spring 802 is parallel to the rotation plane of the first long axis 4011 and the second long axis 4021.

[0081] The first buffer compression spring 801 and the second buffer compression spring 802 are used to reduce the mechanical vibration generated when the first connecting shaft lever 401 and the second connecting shaft lever 402 start to swing and the swing and oscillation at the end of the swing, so as to ensure the smooth operation of the fixing and separating device 100.

[0082] During implementation, after each ejection compression spring releases its elastic potential energy, it will drive the vibration of each connecting lever inside the fixed separation device 100. Therefore, setting the first buffer compression spring 801 and the second buffer compression spring 802 can weaken the vibration amplitude of the long axis of each connecting lever, thereby weakening the mechanical vibration inside the fixed separation device 100 and ensuring the stable operation of the placement platform.

[0083] Specifically, the first buffer compression spring sleeve rod 105 and the second buffer compression spring sleeve rod 106 are fixed on the loading plate 103 through a first protrusion and a second protrusion respectively.

[0084] As a preference, see Figure 6 and Figure 7 The placement frame 900 is provided with two groups of jacks, which are evenly distributed vertically on the side of the vertical rod 901 of the placement frame 900. Correspondingly, two fixing and separating devices 100 are fixed on the placement platform, and one end of each fixing and separating device 100 is plugged into the placement frame 900, and the other end is fixed to the placement platform. In this way, a uniform fixing force and ejection force can be provided for the placement frame 900, and a stable connection between the placement platform and the placement frame 900 can be achieved.

[0085] Specifically, each of the ejection compression springs and anchor nuts mentioned above has a small size and needs to withstand a large external impact force. In order to make the connection more stable, each of the ejection compression springs and anchor nuts are processed from titanium alloy.
