Description

Technical Field

[0001] The utility model relates to the technical field of transport vehicle frames, in particular to a sliding component and a logistics vehicle. Background Art

[0002] Logistics vehicles are the mainstream mobile container equipment for transporting and storing materials. They are often used in logistics operation lines and are a powerful tool for industrial transportation. Logistics vehicles are generally equipped with racks for stacking materials. The storage space is large and stable, which can ensure that materials do not scatter during transportation and ensure the safety of workers and materials during transportation.

[0003] With the development of the logistics industry, more and more materials are transported by logistics vehicles. The staff are busy loading and unloading materials on the carriers or unloading them from the carriers. The handling work is intensive, time-consuming and labor-intensive. Therefore, a movable carrier is set on the chassis platform of the logistics vehicle to facilitate loading and unloading of materials.

[0004] However, in the prior art, since the supporting load frame required for large-scale logistics vehicles is relatively heavy and difficult to control its movement, how to stably realize the flipping action of the load frame and the chassis platform remains a difficult problem. Since the movement stroke of the load frame is too long, it not only occupies a large space, but also it is easy for deformation or misalignment to occur between the various mechanisms, and jamming and interference often occur, resulting in the load frame being unable to move normally, reducing work efficiency.

[0034] like Figures 1 to 5 As shown in the figure, the utility model discloses a sliding assembly for assisting the logistics vehicle to flip the cargo rack 200. The sliding assembly includes a slide rail 500 and a slide frame 600. The slide rail 500 is fixed on the chassis platform 100 of the logistics vehicle. The slide frame 600 is slidably connected to the slide rail 500 along the vehicle length direction of the logistics vehicle; one end of the sliding frame 600 is fixedly provided with a cargo rack connector 630, and the cargo rack connector 630 is rotatably connected to the rotating shaft of the cargo rack 200; the other end of the sliding frame 600 is fixedly provided with a first telescopic assembly mounting bracket 610, and the first telescopic assembly mounting bracket 610 is used to rotatably connect the flip telescopic rod 300. The sliding frame 600 is also provided with a second telescopic assembly mounting bracket 620, which is arranged between the carrier connecting member 630 and the first telescopic assembly mounting bracket 610. The second telescopic assembly mounting bracket 620 is used to fix the translation telescopic rod 400. The first telescopic assembly mounting bracket 610 and the second telescopic assembly mounting bracket 620 are staggered. The carrier connecting member 630, the second telescopic assembly mounting bracket 620 and the first telescopic assembly mounting bracket 610 are arranged in sequence on the sliding frame 600, which effectively reduces the telescopic stroke required for the translation and flipping of the carrier 200 and reduces the space occupied by the sliding assembly. The sliding frame 600 can simultaneously fix the carrier 200, the flip telescopic rod 300 and the translation telescopic rod 400, and the synchronous sliding improves the displacement consistency, which can more stably assist the logistics vehicle to complete the action of flipping the carrier 200 to prevent jamming or interference. Exemplarily, the first telescopic assembly mounting bracket 610 and the flip telescopic rod 300 are hinged by a pin.

[0035] Specifically, two slide rails 500 are symmetrically arranged in parallel along the width direction of the logistics vehicle. Correspondingly, the sliding frame 600 includes two side rods 601. Both ends of the cargo rack connecting piece 630, the first telescopic component mounting bracket 610 and the second telescopic component mounting bracket 620 are respectively connected to the two side rods 601. The relative sliding of the sliding assembly is more stable, and the relative positions of the cargo rack connecting piece 630, the first telescopic component mounting bracket 610 and the second telescopic component mounting bracket 620 are further stabilized to prevent the sliding assembly from being deformed during assembly.

[0036] In this embodiment, the sliding frame 600 includes a plurality of reinforcement parts 602, the two ends of the reinforcement parts 602 are respectively connected to the two side rods 601, and the reinforcement parts 602 are connected to the cargo rack connector 630 or the first telescopic component mounting bracket 610 or the second telescopic component mounting bracket 620, thereby further improving the structural strength of the sliding bracket.

[0037] Optionally, a first slider 640 is provided between the sliding frame 600 and the slide rail 500. The first slider 640 is slidably connected to the slide rail 500 and fixedly connected to the sliding frame 600, so as to avoid direct large-area sliding contact between the sliding frame 600 and the slide rail 500, thereby reducing sliding resistance and improving sliding efficiency; and avoiding wear caused by long-term sliding that affects the service life of the sliding frame 600. The first slider 640 can be replaced separately, thereby reducing the cost of replacing and repairing the sliding component. For example, a plurality of first sliders 640 can be evenly arranged at preset intervals along the length of the vehicle.

[0038] Since the sliding frame 600 has a certain length, in order to stably install the sliding frame 600 and reduce the risk of its deformation, a second slider 650 is added between the first telescopic component mounting bracket 610 and the sliding frame 600. The second slider 650 is slidably connected to the slide rail 500 and fixedly connected to the sliding frame 600, which can strengthen the support for the first telescopic component mounting bracket 610 and the sliding frame 600, improve the stability of the relative sliding between the slide rail 500 and the first telescopic component mounting bracket 610, and extend the service life of the sliding component.

[0039] Furthermore, a third slider 660 is provided at the other end of the sliding frame 600, i.e., between the carrier connector 630 and the sliding frame 600. The third slider 660 is slidably connected to the slide rail 500 and fixedly connected to the sliding frame 600, which can strengthen the support for the carrier connector 630 and the sliding frame 600 and further balance and stabilize the structure of the sliding frame 600.

[0040] In this embodiment, the rack connector 630 is provided with two connecting ears 631 at intervals, and the two connecting ears 631 are respectively tilted upward, so that the rotating shafts sleeved in the two connecting ears 631 are located above the sliding frame 600, avoiding interference between the rack 200 and the sliding assembly. Specifically, the rack connector 630 also includes a reinforcing portion 632, which is fixedly connected between the two connecting ears 631 along the tilting direction of the two connecting ears 631, reinforcing the structure of the rack connector 630, so that the assembly of the sliding assembly and the rack 200 is more stable.

[0041] Optionally, a bearing portion is provided on the carrier connecting member 630, and the carrier connecting member 630 is rotatably connected to the carrier 200 via the bearing portion, the outer ring of the bearing portion is fixedly connected to the carrier connecting member 630, the inner ring of the bearing portion is fixedly sleeved on the rotating shaft of the carrier 200, and the inner ring of the bearing portion is coaxially rotatably connected with the outer ring of the bearing portion, which can support the carrier connecting member 630, reduce the friction coefficient during movement, ensure the rotation effect of the structure, and prevent jamming.

[0042] It can be understood that limit retaining rings are arranged on both sides of the inner ring of the bearing part, and the limit retaining rings are fixedly mounted on the rotating shaft. The two limit retaining rings can ensure that there is no axial relative displacement between the rotating shaft and the carrier connecting piece 630, thereby preventing the carrier 200 from moving unsteadily and affecting the assembly effect of the sliding component and the carrier 200 on the logistics vehicle.

[0043] The utility model also provides a logistics vehicle, including a carrier 200, a chassis platform 100, a flip telescopic rod 300, a translation telescopic rod 400 and the above-mentioned sliding assembly, wherein the two ends of the translation telescopic rod 400 are respectively fixedly connected to the second telescopic assembly mounting bracket 620 and the chassis platform 100 to limit the relative position of the chassis platform 100 and the translation telescopic component, and the two ends of the flip telescopic rod 300 are respectively rotatably connected to the first telescopic assembly mounting bracket 610 and the rotating shaft to limit the relative position of the carrier 200 and the flip telescopic component. The carrier 200 can slide relative to the slide rail 500 and the sliding frame 600 to transform the carrier 200 into a loading state relatively horizontal to the chassis platform 100 or a relatively vertical unloading state, thereby improving the efficiency of the flipping action and ensuring the stability of the flipping of the carrier 200.

[0044] Specifically, in order to further optimize the translation and flipping path of the cargo rack 200, a fixed bracket is arranged on the chassis platform 100, and the two ends of the translation telescopic rod 400 are fixedly connected to the second telescopic assembly mounting bracket 620 and the fixed bracket respectively. At the same time, the translation telescopic rod 400 is arranged in parallel with the slide rail 500 and the chassis platform 100, and the projections of the translation telescopic rod 400 and the flipping telescopic rod 300 on the chassis platform 100 are parallel and spaced, so that the movement path of the cargo rack 200 is smoother.

[0045] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
