Description

Technical Field

[0001] The invention relates to the technical field of logistics transportation, and in particular to a dumping device for mechanical logistics transportation. Background Art

[0002] Dump trucks are a common type of truck used in logistics, also known as tipping trucks. They are composed of a car chassis, a hydraulic lifting mechanism, a cargo compartment, and a power take-off device. The compartment of a dump truck can be divided into two types: rearward tipping and sideward tipping. The piston rod movement is controlled by the operating system. Rearward tipping is more common, and the piston rod is pushed to tip the compartment. A few cases of two-way tipping, whether sideways or backwards, are currently unable to achieve the dumping of most mechanical equipment. The main reason is that existing dump trucks roughly dump the loaded goods into warehouses or designated unloading areas, and most mechanical equipment is relatively delicate. If the dumping method is used to unload during the unloading process, there is a high probability that the equipment will be damaged. Conventionally, only hoisting or forklifts can be used to unload the equipment one by one, which is inefficient. Summary of the invention

[0015] The present invention has the following beneficial effects:

[0016] 1. This kind of mechanical logistics transportation dumping device moves the mechanical equipment by setting a transport vehicle with a detachable equipment fixing seat. Correspondingly, a discharge platform is also set to cooperate with the transport vehicle. The equipment fixing seat is connected to the transport vehicle in a snap-fit ​​manner. When the transport vehicle dumps, the goods can be quickly cleaned through the discharge mechanism at the discharge platform. Specifically, the transport vehicle lifts the carriage through a hydraulic cylinder, and then the discharge mechanism works. At this time, the movable support platform is in an inclined state. Driven by the travel motor, the moving seat climbs along the rack until the discharge arm is inserted into the cavity inside the seat body through the opening. During the process, the unloading arm contacts the second limit plate in the cavity. Driven by the unloading arm, the second limit plate separates with the clamping teeth from the clamping groove on the limit seat. At this time, the seat body can move freely, and then the movable support platform returns to its original position driven by the walking motor. During this process, the movable support platform can move downward by supporting the seat body and the items fixed on the seat body through the unloading arm. When it reaches the low position, the movable support platform rotates. Driven by the movable support platform, the unloading arm and the seat body rotate to a state parallel to the ground. Then, you only need to put an inclined plate on the end of the seat body away from the unloading arm, and then push the items on the seat body down one by one through the inclined plate.

[0017] The present invention provides a detachable equipment fixing seat on the transport vehicle, and then provides an unloading platform used in conjunction with the unloading platform. Through the cooperation between the unloading platform and the transport vehicle, the mechanical equipment carried by the transport vehicle can be directly unloaded by a dumping method, which greatly reduces the difficulty of unloading and improves the unloading efficiency.

[0018] 2. The mechanical logistics transportation dumping device is provided with a seat body with legs. Under normal circumstances, the legs are in a state nearly parallel to the seat body. When the seat body slides down from the carriage and loses the resistance of the carriage, the legs pop out under the push of the first torsion spring and are in a state perpendicular to the seat body. In this way, when the movable support platform is laid flat, the legs can support the seat body and provide better stability.

[0019] A push rod is provided inside the seat body, and a limit column is provided on the movable seat correspondingly. When the seat body is separated from the carriage, the connecting seat moves on the movable seat with the unloading arm. During this process, the push rod collides with the limit column. Under the influence of the limit column, the push rod overcomes the resistance of the second spring and slides relative to the seat body, and then is inserted into the limit hole on the support leg, which plays a role of limiting the support leg and further improves the stability of the support leg.

[0020] 3. A dumping device for mechanical logistics transportation is provided with a movable plate at the driving plate. After unloading the goods, the transport vehicle leaves the unloading platform through the driving plate and the movable plate. In this process, the transport vehicle will press the movable plate down to a certain extent, and one end of the movable plate will contact with the limiting cross bar. The limiting cross bar is provided with an inclined surface on the side close to the movable plate. Under the push of the movable plate, the limiting cross bar will translate with the third limiting plate. During its movement, the third limiting plate contacts with the lifting seat. The side of the lifting seat close to the third limiting plate is also provided with an inclined surface. Under the push of the third limiting plate, the lifting seat moves upward, and the support arm and the hook rod rise synchronously. During its movement, one end of the hook rod contacts with the transmission rod, thereby causing the transmission rod to deflect. At this time, the transmission rod presses the first limiting plate downward, and the limiting protrusion retracts into the seat body, so that the equipment on the seat body can be conveniently moved;

[0021] The present invention provides a driving plate with a movable plate, and utilizes the movement of the transport vehicle after unloading to automatically adjust the first limit plate, thereby automatically releasing the limit of the equipment caster by the limit protrusion after unloading.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] For example, see Figures 1 to 9The present invention discloses a dumping device for mechanical logistics transportation, including a discharge platform 1 and a transport vehicle 2, wherein the transport vehicle 2 is provided with a detachable equipment fixing seat 3, the equipment fixing seat 3 includes a seat body 4, and one end of the seat body 4 is engaged and connected with the transport vehicle 2, a cavity 401 is provided inside the seat body 4, and a first limiting plate 402 is provided in the cavity 401, the first limiting plate 402 is elastically connected to the seat body 4 through a first spring 403, and a plurality of limiting protrusions 404 are provided on the first limiting plate 402, and an insertion interface 405 is provided at one end of the seat body 4;

[0034] A driving plate 5 is provided on one side of the unloading platform 1, and a unloading mechanism for unloading the equipment fixed seat 3 is provided on the other side of the unloading platform 1. The unloading mechanism includes a movable support platform 6, and the movable support platform 6 is rotatably connected to the unloading platform 1. A moving component and a rack 8 are provided on the movable support platform 6. The rack 8 is fixedly connected to the movable support platform 6. The moving component includes a moving seat 7, and the moving seat 7 is provided with a traveling motor 9 for driving the moving seat 7 to move along the rack 8. The moving seat 7 is provided with a unloading arm 10 that matches the plug interface 405.

[0035] The mechanical equipment is moved by setting a transport vehicle 2 with a detachable equipment fixing seat 3. Correspondingly, a discharge platform 1 is also set to cooperate with the transport vehicle 2. The equipment fixing seat 3 is connected to the transport vehicle 2 in a snap-fit ​​manner. When unloading, the hydraulic cylinder is started to lift up the cargo box of the transport vehicle 2 and make it flip backward. Then the discharge mechanism works. At this time, the movable support platform 6 is in an inclined state. The travel motor 9 is connected to the rack 8 through the gear. Driven by the travel motor 9, the mobile seat 7 climbs along the rack 8 until the discharge arm 10 is inserted into the cavity 401 inside the seat body 4 through the opening 407. In this process, the discharge arm 10 conflicts with the second limit plate 408 in the cavity 401. Driven by the discharge arm 10, the second limit plate 408 is separated from the slot 36 on the limit seat 34 with the snap teeth 409. At this time, the seat body 4 can move freely. 4 slides down under the influence of its own gravity, and the movable support platform 6 returns to its original position under the drive of the walking motor 9. During this process, the movable support platform 6 can move downward by supporting the seat body 4 and the articles fixed on the seat body 4 through the unloading arm 10. When it reaches the low position, the movable support platform 6 rotates. Driven by the movable support platform 6, the unloading arm 10 and the seat body 4 rotate to a state parallel to the ground. Then, it is only necessary to put an inclined plate on the end of the seat body 4 away from the unloading arm 10, and then push the articles on the seat body 4 down one by one through the inclined plate, which saves time and effort. The present application arranges a detachable equipment fixing seat 3 on the transport vehicle 2, and then arranges a unloading platform 1 used in conjunction with it. Through the cooperation of the unloading platform 1 and the transport vehicle 2, the mechanical equipment carried by the transport vehicle 2 can be directly unloaded by dumping, which greatly reduces the difficulty of unloading and improves the unloading efficiency.

[0036] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 A moving assembly is provided on the moving seat 7, and the moving assembly includes a first motor 11, a screw rod 12 and a connecting seat 13. The connecting seat 13 is fixedly connected to the unloading arm 10, and the connecting seat 13 is slidingly connected to the moving seat 7 through a first slide rail 14. The screw rod 12 is rotationally connected to the moving seat 7, and the screw rod 12 is transmission-connected to the connecting seat 13 through a screw rod nut. The first motor 11 is fixedly connected to the moving seat 7, and the output shaft of the first motor 11 is fixedly connected to the screw rod 12.

[0037] A leg 15 is provided at the lower side of the seat body 4 . The leg 15 is elastically connected to the seat body 4 via a first torsion spring 16 . A limiting hole 18 is provided at one end of the leg 15 , and a roller 17 is provided at the other end of the leg 15 .

[0038] A push rod 19 is provided inside the seat body 4 , and the push rod 19 is elastically connected to the seat body 4 through a second spring 20 . A plug 21 that fits with the limiting hole 18 is provided at one end of the push rod 19 , and a limiting column 22 is provided on the movable seat 7 .

[0039] The movable seat 7 is slidably connected with the movable support platform 6 through the guide rail. Since the specifications of the transport vehicle 2 are large and small, and the chassis are also high and low, in order to be able to be used for transport vehicles 2 of different heights, the present invention is provided with a moving assembly on the movable seat 7, which includes a first motor 11, a screw rod 12 and a connecting seat 13. The first motor 11 and the screw rod 12 can drive the connecting seat 13 to move, and the connecting seat 13 can drive the unloading arm 10 to move. In order to better complete the unloading, the present invention also provides a support leg 15 on one side of the seat body 4, and the support leg 15 is elastically connected to the seat body 4 through a first torsion spring 16. Under normal circumstances, the support leg 15 is in a state of being nearly parallel to the seat body 4. When the seat body 4 slides down from the car body, after losing the resistance of the car body, the support leg 15 pops out under the action of the first torsion spring 16 and is in a state perpendicular to the seat body 4. In this way, when the movable support platform 6 is deflected, the support leg 15 can play a supporting role on the seat body 4, and the stability is better.

[0040] A push rod 19 is provided inside the seat body 4, and a corresponding limiting column 22 is provided on the moving seat 7. When the seat body 4 is separated from the carriage, the connecting seat 13 moves with the unloading arm 10 on the moving seat 7. During this process, the push rod 19 conflicts with the limiting column 22. Under the influence of the limiting column 22, the push rod 19 overcomes the resistance of the second spring 20 and slides relative to the seat body 4, and then is inserted into the limiting hole 18 on the support leg 15, thereby limiting the support leg 15 and further improving the stability of the support leg 15.

[0041] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 A notch 501 is provided at the lower end of the driving plate 5 , and a movable plate 23 is provided at the notch 501 , and one end of the movable plate 23 is elastically connected to the driving plate 5 through a second torsion spring 24 .

[0042] A movable plate limiting mechanism is provided inside the unloading platform 1, and the movable plate limiting mechanism includes a third limiting plate 25, the third limiting plate 25 is elastically connected to the unloading platform 1 through a third spring 26, and a limiting cross bar 27 is provided on one side of the third limiting plate 25, and an inclined surface is provided on the other side of the third limiting plate 25.

[0043] A first adjustment mechanism is also provided inside the unloading platform 1, and the first adjustment mechanism is located on one side of the third limit plate 25. The first adjustment mechanism includes a support arm 28 and a lifting seat 29. One end of the support arm 28 is fixedly connected to the lifting seat 29, and a hook rod 30 is provided on the support arm 28. The lifting seat 29 is elastically connected to the unloading platform 1 through a reset spring 31.

[0044] A transmission rod 32 is provided on one side of the seat body 4 and is rotatably connected to the seat body 4 . An extension block 406 is provided on the side of the first limiting plate 402 , and one end of the extension block 406 passes through the seat body 4 and contacts one end of the transmission rod 32 .

[0045] A movable plate 23 is arranged at the driving plate 5. After unloading, the transport vehicle 2 leaves the unloading platform 1 through the driving plate 5 and the movable plate 23. During this process, the transport vehicle 2 will press the movable plate 23 down to a certain extent, and one end of the movable plate 23 will contact with the limiting cross bar 27. The limiting cross bar 27 is provided with an inclined surface on the side close to the movable plate 23. Under the push of the movable plate 23, the limiting cross bar 27 will translate with the third limiting plate 25. During its movement, the third limiting plate 25 and The lifting seat 29 is in conflict with the lifting seat 29, and a side of the lifting seat 29 close to the third limiting plate 25 is also provided with an inclined surface. Under the push of the third limiting plate 25, the lifting seat 29 moves upward, and the support arm 28 and the hook rod 30 rise synchronously. During the movement, one end of the hook rod 30 conflicts with the transmission rod 32, thereby causing the transmission rod 32 to deflect. At this time, the transmission rod 32 presses the extension block 406 and the first limiting plate 402 downward, and the limiting protrusion 404 retracts into the seat body 4, so that the equipment on the seat body 4 can be conveniently moved;

[0046] The present invention provides a driving plate 5 with a movable plate 23, and utilizes the movement of the transport vehicle 2 after unloading to automatically adjust the first limiting plate 402, thereby automatically releasing the limiting protrusion 404 from limiting the equipment caster after unloading.

[0047] In actual use, an electromagnet can be set on the lifting seat 29. When the lifting seat 29 rises to the highest point, the electromagnet works to adsorb the lifting seat 29 and the unloading platform 1 together, so that even if the transport vehicle 2 drives away from the movable plate 23, the lifting seat 29 will not return to its original position; the transport vehicle 2 can also be kept pressed on the movable plate 23, and the transport vehicle 2 can be driven away when the unloading is completely completed;

[0048] The unloading platform 1 is a hollow structure, and a side door is provided on the side of the unloading platform 1 . When the movable supporting platform 6 lays the base 4 flat, the operator opens the side door and enters the unloading platform 1 to transfer the equipment on the base 4 .

For details, please refer to Figures 1 to 9 A plurality of openings 407 are provided on the seat body 4, and the openings 407 are connected to the cavity 401, and the positions and numbers of the openings 407 correspond one to one with the limiting protrusions 404, a second limiting plate 408 is provided inside the cavity 401, and the second limiting plate 408 is elastically connected to the seat body 4 through the tension spring 33, and a latching tooth 409 is provided on the second limiting plate 408.

[0050] The transport vehicle 2 is provided with a limit seat 34 for engaging with the seat body 4, and a slot 35 is provided in the middle of the limit seat 34. One end of the limit seat 34 is provided with a slot 36 that fits with the latch tooth 409, and the slot 36 is connected to the slot 35.

[0051] When fixing mechanical equipment with casters, the casters of the equipment can be limited by the limiting protrusion 404 to prevent the equipment from rolling arbitrarily due to the presence of the casters during transportation. A limiting seat 34 is provided on the transport vehicle 2, and a slot 35 is provided inside the limiting seat 34. During transportation, one end of the seat body 4 is inserted into the slot 35. The limiting seat 34 can limit the seat body 4 to prevent it from rolling arbitrarily during transportation. During unloading, the limiting seat 34 cooperates with the slot 35 to guide the seat body 4, so that it can be more stable during the sliding process.
