[0003] In actual use, it was found that the forklift mechanism of the aforementioned unit bracket transport vehicle is only suitable for items with flat bases. When it is necessary to move multiple small but heavy items, the forklift mechanism cannot be used, thus limiting the application range of the aforementioned unit bracket transport vehicle.

[0004] Therefore, it is necessary to improve the existing tracked unit support transport vehicle. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a tracked unit support transport vehicle that can transport multiple small items and has a wide range of applications.

[0006] To solve the above-mentioned technical problems, this utility model provides a tracked unit support transport vehicle, including a vehicle body, a tracked walking unit disposed below the vehicle body, and a fork assembly disposed in front of the vehicle body. The fork assembly includes a mounting plate, two sets of forks connected to the mounting plate, and a load-bearing plate detachably and fixedly connected to the forks. The load-bearing surface of the load-bearing plate is disposed above the forks.

[0007] According to one embodiment of the present invention, a sleeve is fixedly provided at the bottom of the bearing plate, the fork is inserted through the sleeve, and a fixing component for fixing the position of the bearing plate is provided between the bearing plate and the fork.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] like Figure 1-8 As shown, the tracked unit support transport vehicle of this utility model includes a vehicle body 1, a tracked walking unit 2 disposed below the vehicle body 1, and a fork assembly 3 disposed in front of the vehicle body 1. The fork assembly 3 includes a mounting plate 4, two sets of forks 5 connected to the mounting plate 4, and a bearing plate 6 detachably and fixedly connected to the forks 5. The bearing surface of the bearing plate 6 is disposed above the forks 5.

[0019] This design addresses a core deficiency in existing unit-support transport vehicles—they can only move items with flat bases using forks and forks, and cannot handle multiple small, fragmented items. When multiple small items need to be moved, the support plate and forks can be assembled and fixed, using the flat surface of the support plate to support multiple small items, preventing them from falling through the gaps between the forks and forks or becoming unstable. When moving items with flat bases, the support plate can be detached, retaining the original moving function of the forks and forks. This "detachable support plate" design allows the transport vehicle to adapt to both the traditional flat-type item moving needs and the multiple small item moving needs, achieving "one vehicle for multiple uses" and significantly improving the equipment's practicality and the range of applicable scenarios.

[0020] According to one embodiment of the present invention, a sleeve 61 is fixedly provided at the bottom of the bearing plate 6, the fork 5 is inserted through the sleeve 61, and a fixing component for fixing the position of the bearing plate 6 is provided between the bearing plate 6 and the fork 5.

[0021] This design enables precise positioning and initial fixation, reducing the difficulty of assembly and disassembly: the sleeve provides a clear installation guide for the load-bearing plate—simply align the sleeve with the fork and insert it to quickly complete the initial alignment of the load-bearing plate and the fork without repeated adjustments.

[0022] Enhanced connection stability and prevention of displacement during handling: The sleeve limits the range of movement of the carrier plate, and the fixing components further lock its position, which can effectively prevent the carrier plate from shifting or even slipping due to vehicle movement and bumps when handling multiple small items, ensuring the stability of the small item handling process and reducing the risk of items falling.

[0023] According to one embodiment of the present invention, the fixing component includes a limiting pin 7, the bearing plate 6 and the sleeve 61 are provided with a through hole 62, the fork 5 is provided with a through hole, the limiting pin 7 is inserted into the through hole 62 and the through hole, and the limiting pin 7 is fixedly provided with a limiting ring 71 that abuts against the bearing plate.

[0024] This design achieves rigid locking of the three components, preventing relative displacement during handling: the limiting pin passes through the through holes of the bearing plate, sleeve, and fork, physically connecting the bearing plate, sleeve, and fork in a rigid connection structure. This design completely restricts the sliding of the bearing plate along the length of the fork and the rotation around the fork. Especially when handling multiple small items, where the bearing plate has a distributed load, this locking method prevents the plate from shifting due to vehicle bumps or turns, preventing small items from slipping off the edge of the plate and ensuring handling stability.

[0025] According to one embodiment of the present invention, the fixing component further includes a limiting member to prevent the limiting pin 7 from separating from the bearing plate 6.

[0026] This design prevents the limit pin from accidentally coming loose, ensuring safe handling: The limit pin is the core locking component between the load-bearing plate and the forks. If the pin accidentally comes loose from the through hole or perforation during handling (such as when the vehicle is bumpy, turning, or carrying multiple small items), the load-bearing plate will lose its fixation, sway with the forks, or even slip off, which may lead to safety issues such as small items falling and being damaged, or equipment collisions.

[0027] According to one embodiment of the present invention, the limiting member includes an elastic buckle 8, the lower section of the limiting pin 7 is provided with a limiting hole 72, the elastic buckle 8 is provided with a through rod 81 passing through the limiting hole 72, the elastic buckle 8 also includes a V-shaped section 82 connected to the through rod 81, and the V-shaped section 82 is provided on one side of the limiting pin 7.

[0028] This design precisely locks the pin, completely eliminating the risk of accidental detachment: even if the vehicle body is bumpy during transportation or the load-bearing plate is impacted by the weight of small items, the rod can be firmly locked in the limiting hole, preventing the limiting pin from coming out of the through hole of the load-bearing plate and the sleeve.

[0029] According to one embodiment of the present invention, the distance between the two forks 5 is adjustable, the forks 5 are slidably connected to the mounting plate 4, the sliding direction of the mounting plate 4 is parallel to the length direction of the mounting plate 4, and a locking component for fixing the forks 5 to the current position is provided between the forks 5 and the mounting plate 4.

[0030] This design adapts to items of different sizes, overcoming the limitation of single-size handling: Existing fixed-gap forks and shovels can only handle items with a specific width of flat base. When encountering items that are too wide or too narrow, they either cannot provide stable support (e.g., narrow items easily slip through the fork-shovel gap) or cannot be inserted to the bottom (e.g., wide items exceed the fork-shovel coverage). However, the adjustable fork-shovel spacing allows for flexible adjustment of the distance between the two forks and shovels based on the width of the object being handled (e.g., different sizes of unit supports, large flat pieces, or different sizes of load-bearing flat plates used later). This ensures that the forks and shovels are always "precisely aligned and stably lifted," solving the limitation of fixed-gap forks and shovels "only able to handle items of specific sizes."

[0031] According to one embodiment of the present invention, the locking component includes a threaded hole 41 disposed on the upper wall of the mounting plate 4, a hole 511 disposed on the slider 51 of the fork shovel 5, and a bolt 52 passing through the hole 511 and threadedly connected to the threaded hole 41; a plurality of threaded holes 41 are provided along the length direction of the mounting plate 4.

[0032] This design allows for flexible adjustment of the fork spacing while ensuring the stability and adaptability of the adjusted position, and also takes into account ease of operation, further supporting the core requirement of the pallet truck to "adapt to items of multiple sizes".

[0033] According to one embodiment of the present invention, the mounting plate 4 is provided with a shielding member for covering the unused threaded hole 41.

[0034] This design prevents impurities from entering and protects the integrity of the threaded hole structure. If an unused threaded hole is exposed, common debris in handling scenarios, such as dust, gravel, oil, and coolant, can easily enter. On one hand, this can clog the thread clearance, preventing bolts from being properly screwed in when adjusting the forklift spacing later. On the other hand, hard impurities may wear down the thread profile, compromising the thread fit accuracy and reducing the locking effect between the bolt and the threaded hole. The shielding component completely covers the unused threaded hole, forming a physical barrier that prevents impurities from entering at the source, ensuring the threaded hole remains clean and intact, and does not affect subsequent use.

[0035] According to one embodiment of the present invention, the shielding component includes a sealing sleeve 9, the upper wall of the mounting plate 4 is provided with an elastic groove 42, the sealing sleeve 9 is provided with an elastic protrusion 91 that is inserted and engaged with the elastic groove 42; the sealing sleeve 9 and the threaded hole 41 are provided in a one-to-one correspondence.

[0036] This design allows for easy assembly and disassembly without the need for tools, and does not increase the operational burden. The interlocking structure of the flexible protrusion and groove eliminates the need for screwdrivers, wrenches, or other tools. Workers can simply press the sealing sleeve gently to engage the protrusion and groove (installation) or pull it apart with a little force (disassembly). This "tool-free and quick operation" design avoids the situation where workers are unwilling to use the sealing sleeve due to complicated assembly and disassembly (preventing the protection from becoming merely a formality), while also allowing for quick removal of the corresponding sealing sleeve and access to the threaded hole when the fork and spatula spacing needs to be adjusted, without delaying the spacing adjustment efficiency. It perfectly balances "protective effect" and "operational convenience".

[0037] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
