Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a transition platform and trolley. Background Technology

[0002] Freight transport vehicles are important vehicles for transporting materials. The cargo compartments of freight vehicles are designed with different heights and steps depending on the vehicle's shape. When loading and unloading goods in the cargo compartment, it is necessary to cross steps of different heights.

[0003] In the prior art, when using a transfer trolley to load goods into a carriage, the transfer trolley can move the goods to the carriage, and then, in conjunction with a hoisting structure or other lifting structure, adjust the height of the goods to complete the loading of goods on step planes of different heights.

[0004] However, the different step heights in different carriages mean that during the loading and unloading process, multiple pieces of equipment need to work closely together to ensure that the goods can be smoothly transferred between different steps. This makes the loading and unloading process cumbersome, difficult, and inefficient. Utility Model Content

[0005] The purpose of this utility model is to provide a transition platform and trolley, which solves the problem in the prior art that when loading and unloading goods in a car with steps, multiple devices need to be used in precise coordination to complete the process, resulting in a complicated, difficult, and inefficient cargo handling process.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a transitional platform, which includes:

[0008] The connecting platform is used to support the chassis of the trolley;

[0009] A lifting mechanism is connected to the connecting platform to drive the connecting platform and the trolley to rise to a first height, which is greater than the height of the steps inside the carriage.

[0010] A lifting assembly is disposed on the connecting platform and abuts against the chassis of the trolley for lifting the chassis of the trolley;

[0011] A transition component is provided on each side of the connecting platform near the drive unit of the trolley, and a portion of the transition component can extend out to support the drive unit of the trolley.

[0012] Optionally, the transition component includes:

[0013] The connecting plate is slidably connected to the connecting platform;

[0014] A transition platform is fixedly connected to the connecting plate and has a transition plane, which is used to support the drive unit of the trolley.

[0015] A transition drive is connected to the transition platform to drive the transition platform to extend.

[0016] Optionally, the transition platform extends along the length of the trolley, and a plurality of reinforcing parts are distributed at intervals along the extension direction of the transition platform, and the plurality of reinforcing parts are fixedly connected to the connecting plate.

[0017] Optionally, the lifting assembly includes:

[0018] Multiple receiving drive components are arranged circumferentially around the connecting platform, and the output end of each receiving drive component is used to receive the chassis of the trolley.

[0019] Optionally, the lifting mechanism includes:

[0020] The base plate is positioned opposite to the connecting platform;

[0021] The scissor lift assembly has one end mounted on the base plate and the other end connected to the connecting platform;

[0022] A lifting drive unit is connected to the scissor lift assembly to drive the scissor lift assembly to lift the connecting platform.

[0023] Optionally, the top wall of the connecting platform has a positioning post, the chassis of the trolley has a positioning hole for inserting the positioning post, and the positioning post separates from the positioning hole when the drive unit of the trolley is connected to the transition assembly.

[0024] Optionally, the transition platform further includes:

[0025] A locking assembly includes a locking part and a locking block, one of which is disposed on the connecting platform and the other is disposed on the chassis of the trolley. The locking part and the locking block can lock or separate from each other, so that the connecting platform can lock or separate from each other.

[0026] Optionally, multiple locking components are distributed circumferentially around the connecting platform.

[0027] Secondly, this utility model also provides a trolley, which includes:

[0028] The chassis has drive units on both sides;

[0029] The transition platform as described in any one of the first aspects is connected to the chassis.

[0030] Optionally, there is a receiving space between the drive unit and the connecting platform to accommodate the transition component.

[0031] The beneficial effects of this utility model are:

[0032] Firstly, by setting up a connecting platform to support the chassis of the trolley, the transition platform can be detachably connected to the trolley, thus enabling it to be used for the transitional movement of various trolleys. During the transition, the lifting mechanism raises the connecting platform to press against the chassis of the trolley, raising the trolley to the first height. At this point, the lifting component continues to push the trolley up. After the transition component extends, the lifting component resets, and the trolley's drive unit rests on the transition component. The part of the transition component supporting the drive unit aligns with the steps inside the carriage. The rotation of the trolley's drive unit propels the trolley from the transition component towards the steps inside the carriage, facilitating loading and unloading of goods. When the trolley exits the steps, it first enters the transition component, then the lifting component lifts the trolley, the transition component retracts, the lifting component resets, and the lifting mechanism resets. In this way, the trolley can move smoothly between different steps in the carriage. Therefore, when in use, this transition platform forms a detachable connection with the trolley, allowing it to be quickly integrated onto various types of trolleys. Its compact structure enables the trolley to move between different steps in the carriage to load and unload goods, effectively simplifying the loading and unloading process between different steps in the carriage, reducing difficulty, saving time, and effectively improving the efficiency of loading and unloading goods.

[0033] Secondly, by setting a detachable transition platform on the chassis of the trolley, the transition platform can connect to the steps to raise the trolley as needed, so that the trolley can move smoothly between different steps in the carriage, so as to quickly complete the loading and unloading of goods and improve the efficiency of loading and unloading.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0048] This utility model discloses a transition platform, a trolley, and a transition control method.

[0049] Reference Figure 1 and Figure 2 The transition platform includes a connecting platform 1, a lifting mechanism 2, a lifting assembly, and a transition assembly 3. The connecting platform 1 is used to support the chassis 4 of the trolley; the lifting mechanism 2 is connected to the connecting platform 1 to drive the connecting platform 1 and the trolley to rise to a first height, which is greater than the height of the steps inside the trolley; the lifting assembly is disposed on the connecting platform 1 and abuts against the chassis 4 of the trolley to lift the chassis 4 of the trolley; a transition assembly 3 is disposed on each side of the connecting platform 1 near the drive unit 5 of the trolley, and a portion of the transition assembly 3 can extend out to support the drive unit 5 of the trolley.

[0050] Specifically, the connecting platform 1 is flat and located between the two drive units 5 of the trolley. The drive units 5 of the trolley can be wheels or tracks. The connecting platform 1 abuts against the chassis 4 of the trolley, and the two can be detachably connected by means of snap-fit ​​or bolt connection. The lifting mechanism 2 is located below the connecting platform 1, with its lower side resting on the bottom surface. The lifting mechanism 2 can be driven by a motor as the driving element, in conjunction with a lead screw or belt drive structure, to drive the connecting platform 1 to rise and fall, or it can be driven by a hydraulic cylinder in conjunction with a linkage mechanism. The first height is greater than the height of the steps inside the carriage to ensure that after the first height is raised, part of the transition component can be aligned with the steps inside the carriage. The specific first height can be designed according to the height of the steps, and this application does not limit it.

[0051] The lifting assembly can use a cylinder or hydraulic cylinder as the driving component to lift the chassis 4 of the trolley to a specified height in the vertical direction, so that the driving part 5 of the trolley is at a height higher than the transition assembly 3. The transition assembly 3 is provided with a corresponding driving structure that can extend out and correspond vertically with the driving part 5 of the trolley. When the lifting assembly resets, the trolley descends, and the driving part 5 of the trolley lands on the transition assembly 3.

[0052] By setting up a connecting platform 1 to support the chassis 4 of the trolley, the transition platform can be detachably connected to the trolley, thus enabling it to be used for the transition movement of various trolleys. During the transition, the lifting mechanism 2 drives the connecting platform 1 to rise and press against the chassis 4 of the trolley, raising the trolley to the first height. At this point, the part of the transition component 3 that supports the drive unit 5 aligns with the steps inside the carriage. The drive unit 5 of the trolley rotates, causing the trolley to move from the transition component 3 towards the steps inside the carriage, smoothly entering the steps to load and unload goods. When the trolley exits from the steps, it first enters the transition component 3, and then the lifting component lifts the trolley. After that, the transition component 3 retracts, the lifting component resets, and the lifting mechanism 2 resets, allowing the trolley to move smoothly between different steps in the carriage. Therefore, when in use, this transition platform forms a detachable connection with the trolley, allowing it to be quickly integrated onto various types of trolleys. Its compact structure enables the trolley to move between different steps in the carriage to load and unload goods, effectively simplifying the loading and unloading process between different steps in the carriage, reducing difficulty, saving time, and effectively improving the efficiency of loading and unloading goods.

[0053] Optionally, the transition assembly 3 includes a connecting plate 31, a transition platform 32, and a transition drive member 33. The connecting plate 31 is slidably connected to the connecting platform 1; the transition platform 32 is fixedly connected to the connecting plate 31 and has a transition plane, which is used to receive the drive unit 5 of the trolley; the transition drive member 33 is connected to the transition platform 32 to drive the transition platform 32 to extend.

[0054] Specifically, the connecting plate 31 is elongated and extends along the width of the drive unit 5 of the trolley. It is slidably connected to the connecting platform 1 via a slide rail and a slider. A transition platform 32 is fixedly mounted on the end face of the connecting plate 31. The transition platform 32 extends along the length of the drive unit 5 of the trolley and can be L-shaped. Its vertical arm is frame-like, with the top of the vertical arm fixedly connected to the connecting plate 31 and the bottom integral with the horizontal arm. Multiple rod-shaped reinforcing parts 34 are distributed at intervals along the length of the vertical arm to ensure that the strength of the transition platform 32 meets the requirements. The top surface of the horizontal arm of the transition platform 32 serves as a transition plane. After the connecting platform 1 is raised to the first height, the transition plane is flush with the step surface inside the carriage. To improve the load-bearing capacity of the transition plane, multiple connecting plates 31 can be spaced apart along the length of the transition platform 32. In this embodiment, two connecting plates 31 are spaced apart.

[0055] The transition drive 33 is located between the two connecting plates 31 and in the middle of the transition platform. The transition component 3 can be a pneumatic cylinder or a hydraulic cylinder. In this embodiment, the transition drive 33 is a hydraulic cylinder, and the two hydraulic cylinders can share a set of hydraulic control modules so that the transition drive 33 of the two transition components 3 can move synchronously.

[0056] After the trolley is lifted by the lifting assembly, the connecting plate 31 is driven to slide by the transition drive 33. The connecting plate 31 pushes the transition platform 32 to extend, so that the transition plane is located below the drive part 5 of the trolley. When the lifting assembly is reset, the drive part 5 of the trolley will fall on the transition plane. In order to increase the friction of the transition plane, friction textures can be set on the transition plane to ensure that the drive part 5 of the trolley can move relative to the transition plane when rotating.

[0057] Reference Figure 3 Optionally, the lifting assembly includes multiple lifting drive components 6. The multiple lifting drive components 6 are arranged circumferentially around the connecting platform 1, and the output end of each lifting drive component 6 is used to support the chassis 4 of the trolley.

[0058] Specifically, the lifting drive component 6 is a hydraulic cylinder. The cylinder body is fixed to the connecting platform 1, and its piston rod can extend vertically upward. A receiving block is provided at the end of the piston rod, and the top wall of the receiving block is used to support the chassis 4 of the trolley. In this embodiment, the connecting platform 1 is rectangular, and a lifting drive component 6 is provided at each of the four corners of the connecting platform 1 to ensure that the force on the trolley is even during the lifting process. Multiple lifting drive components 6 share a single hydraulic system to ensure that multiple lifting drive components 6 can operate synchronously.

[0059] Reference Figure 4 Optionally, the lifting mechanism 2 includes a base plate 21, a scissor lift assembly 22, and a lifting drive component. The base plate 21 is disposed opposite to the connecting platform 1; one end of the scissor lift assembly 22 is disposed on the base plate 21, and the other end is connected to the connecting platform 1; the lifting drive component is connected to the scissor lift assembly 22 to drive the scissor lift assembly 22 to lift the connecting platform 1.

[0060] Specifically, one side of the base plate 21 is flat, allowing it to rest against a bottom surface or other platform. The other side of the base plate 21 is equipped with a scissor lift assembly 22. The scissor lift assembly 22 includes at least one set of scissor lift units. Each scissor lift unit includes two intersecting and rotatably connected connecting rods, with their upper and lower ends connected to the base plate 21 and the connecting platform 1, respectively. The lifting drive can be a hydraulic cylinder, capable of driving the two connecting rods closer to or further apart, thereby causing the scissor lift assembly 22 to open or close. In this embodiment, the scissor lift assembly 22 includes only one set of scissor lift units.

[0061] When it is necessary to raise the connecting platform 1, the lifting drive is activated. The lifting drive drives the scissor fork assembly 22 to move, which can raise the connecting platform 1 and push the trolley to rise synchronously. Using a hydraulic cylinder as the lifting drive can provide sufficient driving force for the lifting process, ensuring that the connecting platform 1 and the trolley can be raised and lowered smoothly.

[0062] Reference Figure 4 and Figure 5Optionally, the top wall of the connecting platform 1 has a positioning post 11, the chassis 4 of the trolley has a positioning hole for the positioning post 11 to be inserted, and when the drive unit 5 of the trolley is connected to the transition assembly 3, the positioning post 11 is separated from the positioning hole.

[0063] Specifically, the positioning posts 11 are elongated and extend vertically, with multiple positioning posts 11 spaced apart around the circumference of the connecting platform 1. The chassis 4 of the trolley has corresponding positioning holes for the positioning posts 11 to insert into. When the connecting platform 1 is raised, the positioning posts 11 insert into the positioning holes, creating a locking connection between the connecting platform 1 and the chassis 4 of the trolley, ensuring that the connecting platform 1 does not shift from the trolley during the lifting mechanism 2's raising and lowering process. When the lifting assembly raises the trolley, the positioning posts 11 can disengage from the positioning holes. Furthermore, when the trolley's drive unit 5 rests on the transition plane, the positioning posts 11 will not insert into the positioning holes, meaning the height of the positioning posts 11 is less than the distance between the chassis 4 of the trolley and the connecting platform 1 at this time. This allows the trolley to move relative to the transition plane after the drive unit 5 is placed on it.

[0064] Optionally, the transition platform also includes a locking component. The locking component includes a locking part 12 and a locking block 13, one of which is disposed on the connecting platform 1 and the other is disposed on the chassis 4 of the trolley. The locking part 12 and the locking block 13 can lock or separate from each other, so that the connecting platform 1 and the chassis 4 of the trolley can lock or separate from each other.

[0065] Specifically, taking the locking part 12 being installed on the chassis 4 of the trolley as an example, the locking block 13 is installed on the top wall of the connecting platform 1. The locking part 12 can be a hydraulic cylinder, with the piston rod of the hydraulic cylinder extending along the width direction of the trolley. A locking block is provided on the end face of the piston rod, and a locking hole for inserting the locking block is provided on the side of the locking block 13. The locking part 12 can also be driven by a cylinder or a motor. This utility model does not limit this to the following.

[0066] When the connecting platform 1 abuts against the chassis 4 of the trolley, the locking part 12 can extend out of the latch and insert into the locking block 13, so that the locking part 12 and the locking block 13 form a lock, and the connecting platform 1 is locked on the chassis 4 of the trolley. Multiple sets of locking parts 12 and locking blocks 13 can be provided to make the locking effect better. In this embodiment, four sets of locking parts 12 and locking blocks 13 are arranged at intervals.

[0067] By setting the locking part 12 and the locking hole, the connecting platform 1 can be locked on the chassis 4 of the trolley before the trolley is running normally. At the same time, when the lifting mechanism 2 is running, it can also ensure that there is no relative movement between the connecting platform 1 and the chassis 4 of the trolley, so as to ensure that the trolley can be raised smoothly.

[0068] Reference Figure 6 and Figure 7The vehicle includes a chassis 4 and a transition platform as described in the above embodiment. Drive units 5 are provided on both sides of the chassis 4; the transition platform is detachably connected to the chassis 4.

[0069] By setting a detachable transition platform on the chassis 4 of the trolley, the transition platform can raise the trolley according to the height of the steps that the trolley needs to dock with, so that the trolley can move smoothly between different steps in the carriage, so as to quickly complete the flow of goods and improve the efficiency of loading and unloading goods.

[0070] The vehicle in this utility model can be an AVG vehicle or other types of freight vehicles; this utility model does not limit the scope of the invention.

[0071] Optionally, there is a receiving space between the drive unit 5 and the connecting platform 1 to accommodate the transition component 3.

[0072] Specifically, when the connecting platform 1 is locked onto the chassis 4 of the trolley, the side of the connecting platform 1 is opposite to the drive unit 5, and a receiving space is formed between the connecting platform 1 and the drive unit 5, so that the transition platform 32 of the transition component 3 is housed in the receiving space, and the entire transition platform can be stored under the chassis 4 of the trolley. When the trolley needs to move to a platform of a specific height, the transition platform can be remotely controlled and started by the staff, thereby making the transition platform modular and automated.

[0073] Reference Figure 8 The transition control method includes:

[0074] Step S1: Obtain the first height and raise both the connecting platform 1 and the trolley to the first height.

[0075] The first height is greater than the height of the steps inside the carriage, so as to ensure that the transition component 3 installed on the connecting platform 1 can correspond to the steps.

[0076] Step S2: Raise the trolley to the second height.

[0077] Since the connecting platform 1 is pressed against the bottom wall of the trolley, after being raised to the first height, the transition component 3 will be located between the two drive parts 5 of the trolley. Therefore, the trolley is raised to the second height by the lifting component, so that the transition component 3 is misaligned with the drive parts 5 of the trolley.

[0078] Step S3: After the control transition component 3 extends, the trolley is lowered so that the drive unit 5 of the trolley abuts against the transition component 3.

[0079] After the transition platform 32 of the transition component 3 extends, the transition plane of the transition platform 32 corresponds exactly to the drive unit 5 of the trolley. Then, after the drive unit 5 of the trolley is lowered, it will abut against the transition plane. At this time, the transition plane of the transition component 3 is consistent with the height of the step that needs to be connected. Then, the trolley can move on the transition plane and enter the step surface of the carriage that needs to be connected.

[0080] Through the above steps S1 to S3, the trolley can move quickly between different steps in the carriage, and the above control method can be remotely operated by staff, operating in a fully automated manner, enabling the trolley to quickly complete the loading and unloading of goods, effectively improving the loading and unloading efficiency of goods.

[0081] Optionally, the method further includes: obtaining the running status of the trolley; when the trolley is in a moving state, locking the connecting platform 1 to the chassis 4 of the trolley so that the transition platform moves synchronously with the trolley; and when the trolley is in a docking state, releasing the lock between the trolley and the connecting platform 1.

[0082] The trolley's operating state refers to the state in which the trolley moves horizontally on the platform. In this state, the trolley does not need to be raised, but the connecting platform 1 is locked to the chassis 4 of the trolley, so that the trolley can drive the transition platform to move synchronously to the step inside the carriage, so as to ensure that the trolley can dock with the step at the appropriate position. When the trolley is raised to the specified height, the lock is released so that the trolley can move relative to the connecting platform 1.

[0083] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
