Technical Field
[0001] This utility model belongs to the field of green plant transportation technology, and more specifically, it relates to a green plant transportation device with an emergency braking structure. Background Technology
[0002] In garden maintenance, green plant planting bases, and urban greening projects, it is often necessary to move various types of green plants, such as moving seedlings from the nursery area to the planting area, and moving mature plants from the planting site to transport vehicles or designated placement locations. Therefore, a green plant moving device is needed to assist in the handling. Existing green plant moving devices generally use a vehicle frame as the basic framework, equipped with a support plate to carry the green plants, and achieve displacement through wheels at the bottom.
[0003] Existing application number CN202422007425.7 discloses a plant handling device, including a handle, a vertical plate installed at one end of the handle, a sunshade component installed at the top of the vertical plate, a support component installed on one side of the vertical plate, and casters installed at the bottom of the support component; a protective cover is installed on the other side of the vertical plate, a control button is installed at the top of the protective cover, a ventilation opening is installed on one side of the protective cover, a functional component is installed inside the protective cover, and a first partition is installed on the inner wall of the protective cover; this utility model supports the sunshade box by using a third telescopic rod included in the sunshade component, and by manually pulling open the partition strip, the sunshade cloth rolled on the surface of the winding roller is rolled out, and the sunshade cloth is opened by the telescopic support strip. Through the cooperation of the first rotating block and the second rotating block, the purpose of preventing sunlight exposure and adjusting the sunshade angle can be achieved.
[0004] Based on the above, while existing plant handling devices are convenient for transport, most rely on locking casters for braking. The core function of this braking method is primarily to temporarily limit the device during static operations such as loading, unloading, and sorting within the handling area, preventing accidental slippage that could disrupt operations. However, in the dynamic process of actual plant transport, if an emergency occurs, such as when the device tends to slide on a steep slope, or when pedestrians or obstacles suddenly appear requiring immediate stopping, the reliance on locking casters results in a slow response and limited braking force. This makes it inconvenient to quickly and effectively brake to avoid risks, posing a hazard to both plant safety and operator safety. Utility Model Content
[0005] To address the aforementioned technical problems, this utility model provides a plant handling device with an emergency braking structure. While existing plant handling devices are convenient for transport, most rely on locking casters for braking. The core function of this braking method is primarily to temporarily limit the device during static operations such as loading, unloading, and sorting within the handling area, preventing accidental slippage that could disrupt operations. However, during the dynamic process of actual plant transport, if an emergency occurs, such as when traveling on a steep slope causing the device to slip, or when pedestrians or obstacles suddenly appear requiring immediate stopping, the reliance on locking casters results in a slow response and limited braking force, hindering rapid and effective braking to avoid risks. This poses a hazard to both plant safety and operator safety.
[0006] The purpose and function of this utility model's plant handling device with an emergency braking structure are achieved through the following specific technical means:
[0007] A plant transport device with an emergency braking structure includes a transport vehicle body, roller axle assemblies, a protective door, a transfer bracket, a brake frame, a brake cable assembly, a braking component, and a locking component. Two sets of roller axle assemblies are rotatably connected to the bottom of the transport vehicle body. The protective door is hinged to the front of the transport vehicle body. The transfer bracket is welded to the upper part of the transport vehicle body. The brake frame is slidably connected inside the transfer bracket. The brake cable assembly has two ends installed inside the brake frame and at the bottom of the transport vehicle body, respectively. The locking component is located at the bottom of the transport vehicle body.
[0008] Furthermore, the braking assembly includes: a mounting housing and a transmission frame, wherein two sets of mounting housings are provided, and the two sets of mounting housings are fixedly installed on the bottom of the transport vehicle body; the transmission frame is slidably connected to the bottom of the transport vehicle body, and the transmission frame is fixedly installed on one end of the brake cable assembly.
[0009] Furthermore, the braking assembly also includes: a first inclined block and a second inclined block, wherein two sets of the first inclined blocks are provided, and the two sets of the first inclined blocks are fixedly installed at the bottom of the transmission frame; two sets of the second inclined blocks are provided, and the two sets of the second inclined blocks are respectively vertically slidably connected to the interior of the two sets of mounting housings.
[0010] Furthermore, the braking assembly also includes: brake pins, elastic elements, and brake gears. Two sets of brake pins are provided, and the two sets of brake pins are respectively fixedly connected to the bottom of the two sets of second inclined blocks. Two sets of elastic elements are provided, with one end of the two sets of elastic elements respectively fixedly connected to the inside of the two sets of mounting housings, and the other end of the two sets of elastic elements respectively fixedly connected to the bottom of the two sets of second inclined blocks. Two sets of brake gears are provided, and the two sets of brake gears are coaxially fixedly installed in the middle of the two sets of roller shafts.
[0011] Furthermore, the locking assembly includes: a driven rack, a threaded screw, and a drive gear. The driven rack is fixedly installed at one end of the upper part of the transmission frame; the threaded screw is rotatably connected inside the main body of the transport vehicle; the drive gear is coaxially fixedly installed at one end of the threaded screw, and the drive gear and the driven rack mesh with each other.
[0012] Furthermore, the locking assembly also includes a transmission block and a limiting pin. The transmission block is slidably connected inside the main body of the transport vehicle and is threadedly connected to one end of a threaded screw. The limiting pin is fixedly installed on one side of the transmission block.
[0013] Furthermore, the locking assembly also includes a limiting slot, which is located inside the protective door.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] Firstly, this invention features a braking assembly that achieves rapid emergency braking through a mechanical transmission structure. The operator pulls the brake frame, which in turn drives the transmission frame to slide via the brake cable assembly. The inclined surfaces of the first and second inclined blocks work together to convert horizontal displacement into vertical thrust, pushing the brake pin into the brake gear groove and directly restricting the rotation of the roller shaft assembly. Compared to traditional universal wheel locking, this design offers faster response and stronger braking force, effectively addressing emergency scenarios such as sloping roads and sudden obstacles, preventing the device from malfunctioning.
[0016] Secondly, this invention features a locking component that automatically locks the protective door in conjunction with the braking component. When the transmission frame slides, it synchronously drives the driven rack to move, which in turn drives the threaded screw to rotate via the drive gear. This, in turn, pushes the transmission block and the limiting pin to move, causing the pin to insert into the limiting slot of the protective door. In the event of emergency braking, this prevents the plants from accidentally opening the protective door due to inertia, avoiding damage to the plants and further ensuring safe transport.
[0017] This utility model has the advantages of simple operation, emergency braking, and protective door locking. It combines the dual protection of emergency braking and protective door locking, which not only improves the operational safety during the transportation of green plants, but also reduces the possibility of damage to green plants due to accidental transport.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1
[0026] As attached Figure 1 To be continued Figure 5 As shown:
[0027] This utility model provides a plant transport device with an emergency braking structure, including a transport vehicle body 1, roller shaft assembly 2, protective door 3, transfer bracket 4, brake frame 5, brake cable assembly 6, and brake components. The roller shaft assembly 2 is provided in two sets, which are rotatably connected to the bottom of the transport vehicle body 1. The protective door 3 is hinged to the front side of the transport vehicle body 1. The transfer bracket 4 is welded to the upper part of the transport vehicle body 1. The brake frame 5 is slidably connected inside the transfer bracket 4. The two ends of the brake cable assembly 6 are respectively installed inside the brake frame 5 and at the bottom of the transport vehicle body 1.
[0028] The braking assembly includes: a mounting housing 8 and a transmission frame 7. The mounting housing 8 is provided in two sets, and the two sets of mounting housing 8 are fixedly installed at the bottom of the transport vehicle body 1. The transmission frame 7 is slidably connected to the bottom of the transport vehicle body 1 and is fixedly installed at one end of the brake cable assembly 6.
[0029] The braking assembly also includes: a first inclined block 701 and a second inclined block 801. Two sets of the first inclined blocks 701 are provided, and the two sets of the first inclined blocks 701 are fixedly installed at the bottom of the transmission frame 7. Two sets of the second inclined blocks 801 are provided, and the two sets of the second inclined blocks 801 are vertically slidably connected to the interior of the two sets of mounting housings 8 respectively.
[0030] The braking assembly also includes: brake pins 802, elastic elements 803, and brake gears 201. Two sets of brake pins 802 are provided, and the two sets of brake pins 802 are respectively fixedly connected to the bottom of the two sets of second inclined blocks 801. Two sets of elastic elements 803 are provided, and one end of the two sets of elastic elements 803 is respectively fixedly connected to the inside of the two sets of mounting housings 8, and the other end of the two sets of elastic elements 803 is respectively fixedly connected to the bottom of the two sets of second inclined blocks 801. Two sets of brake gears 201 are provided, and the two sets of brake gears 201 are coaxially fixedly installed in the middle of the two sets of roller shaft groups 2.
[0031] The specific usage and function of this embodiment are as follows:
[0032] The brake cable assembly 6 includes a protective and guiding outer shell, a steel wire cable responsible for force transmission, and a spring for resetting. In case of an emergency requiring braking, the operator triggers the braking process by pulling the brake frame 5. As the brake frame 5 slides along the transfer bracket 4, it simultaneously pulls the steel wire cable inside the brake cable assembly 6. Through the linear transmission of the steel wire cable, the transmission frame 7, which is fixedly connected to it, slides smoothly at the bottom of the transport vehicle body 1. During the sliding of the transmission frame 7, the two sets of first inclined blocks 701 fixed at its bottom move together. Because the inclined structures of the first inclined block 701 and the second inclined block 801 are in contact with each other, the horizontal displacement of the first inclined block 701 is converted into a vertical thrust on the second inclined block 801, driving the two sets of second inclined blocks 801 to move within their respective mounting housings 8. The first part slides downwards vertically; when the second inclined block 801 moves downwards, it drives the brake pin 802 fixed at its bottom to move downwards synchronously, and on the other hand, it compresses the elastic element 803 installed between the mounting housing 8 and the second inclined block 801, storing elastic potential energy for subsequent reset after the brake is released; finally, driven by the second inclined block 801, the brake pin 802 is inserted into the tooth groove of the brake gear 201 coaxially fixed in the middle of the roller shaft assembly 2. Through the mechanical engagement of the brake pin 802 and the brake gear 201, the rotation of the roller shaft assembly 2 is directly restricted, thereby quickly realizing the synchronous emergency braking of the two roller shaft assemblies 2, effectively preventing the device from losing control and sliding in emergency scenarios. Example 2
[0033] Based on Example 1, such as Figures 1 to 5 As shown, it also includes a locking component, which is located at the bottom of the transport vehicle body 1.
[0034] The locking assembly includes a driven rack 702, a threaded screw 101, and a drive gear 102. The driven rack 702 is fixedly installed at one end of the upper part of the transmission frame 7. The threaded screw 101 is rotatably connected inside the main body 1 of the transport vehicle. The drive gear 102 is coaxially fixedly installed at one end of the threaded screw 101, and the drive gear 102 and the driven rack 702 mesh with each other.
[0035] The locking assembly also includes a transmission block 103 and a limiting pin 104. The transmission block 103 is slidably connected inside the main body 1 of the transport vehicle and is threadedly connected to one end of the threaded screw 101. The limiting pin 104 is fixedly installed on one side of the transmission block 103.
[0036] The locking assembly also includes a limit slot 301, which is located inside the protective door 3.
[0037] The specific usage and function of this embodiment are as follows:
[0038] The protective door 3 is installed on the front side of the main body 1 of the transport vehicle through a hinge structure. In normal conditions, a simple snap-fit method is used to achieve basic limit. Operators can easily open and close the protective door 3 to conveniently put or take out the green plants into or out of the transport bracket 4, taking into account both ease of operation and basic protection during the handling of green plants.
[0039] When the device triggers the emergency braking process and the transmission frame 7 slides along the bottom of the transport vehicle body 1, the driven rack 702 fixed at one end of its upper part will move horizontally synchronously with the transmission frame 7. Since the driven rack 702 and the drive gear 102 fixed coaxially at one end of the threaded screw 101 mesh with each other, the horizontal displacement of the driven rack 702 will be converted into the rotational motion of the drive gear 102, thereby driving the threaded screw 101 to rotate synchronously inside the transport vehicle body 1. When the threaded screw 101 rotates, it drives the transmission block 103 connected to it to slide along the guide structure inside the transport vehicle body 1 through the threaded transmission action. During the sliding process of the transmission block 103, the limiting pin 104 fixed on one side of it will move together and finally accurately insert into the preset limiting slot 301 inside the protective door 3, realizing the automatic locking of the protective door 3. This can effectively prevent the green plants inside the transport vehicle body 1 from pushing the protective door 3 due to inertial impact force at the moment of emergency braking, and prevent the protective door 3 from accidentally opening and causing the green plants to slide out of the device.
