Description

Technical Field

[0001] This utility model belongs to the field of pallet support technology, and mainly relates to a sliding pallet support. Background Technology

[0002] For vehicles with enclosed cargo boxes, it is difficult for handling equipment to reach inside, making it challenging to load heavy objects into the cargo box using such equipment. Furthermore, even if the objects are loaded manually, it is difficult to unload them later using handling equipment. Utility Model Content

[0003] This invention provides a sliding pallet support to solve the problem in the prior art that goods are difficult to move into the interior of a car with a cargo box.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A sliding pallet support for placement inside a container includes a base frame and a movable component that slides on the base frame. The movable component is used to place goods. The base frame has a track groove with relatively open sides. The movable component has a sliding groove corresponding to the track groove. The sliding groove covers the track groove from top to bottom. A roller is rotatably mounted in the sliding groove and rolls in the track groove to support the sliding of the movable component on the base frame.

[0006] The base frame is provided with a clearance channel that connects to the track groove. The clearance channel connects to the sliding groove on the moving part so that the roller rolls to the clearance channel, lifts the moving part, and the roller moves out of the clearance channel, thus separating the base frame from the moving part.

[0007] It has the following beneficial effects: The sliding groove of the moving part is equipped with rollers, which roll in the track groove of the base frame, transforming the traditional sliding friction into rolling friction, greatly reducing the resistance. Even if the cargo is heavy, the moving part can be pushed into the box along the track more easily when pushed manually or mechanically, avoiding the difficulty of pushing due to excessive friction.

[0008] Furthermore, the movable component is provided with a locking mechanism for fixing the base frame and the movable component together. The locking mechanism includes a sliding component slidably arranged on the movable component, an L-shaped transmission component hinged to the movable component, and an L-shaped pin slidably arranged on the movable component. The middle part of the L-shaped transmission component is hinged to the axis of the movable component extending in the vertical direction. One end of the L-shaped transmission component is hinged to the axis of the sliding component extending in the vertical direction, and the other end is slidably connected to the L-shaped pin. Pulling the movable component allows the L-shaped pin to slide on the movable component, thereby allowing the L-shaped pin to pass through the movable component and be inserted into the base frame.

[0009] It has the following beneficial effect: preventing moving parts from sliding off the base frame.

[0010] Furthermore, the slider is provided with a handle.

[0011] It has the following beneficial effects: it makes it easier for workers to manually control the fixing between the base frame and the moving parts.

[0012] Furthermore, a guide wheel is rotatably mounted on the base frame between the two track grooves. The guide wheel is used to abut against the moving part so that the moving part can move between the guide wheel and the track groove.

[0013] It has the following beneficial effects: when the moving part is deviated by lateral thrust, the guide wheel generates reverse resistance through rolling friction. This passive guiding mechanism does not require electric drive and can achieve automatic correction through mechanical contact only.

[0014] Furthermore, the end of the track groove is provided with a stop wheel, and the stop wheel and the clearance channel are located at the same end.

[0015] Furthermore, a handle is fixed to the movable component.

[0016] It has the following beneficial effects: workers can directly move the movable parts on the base frame by pulling the handle.

[0017] Furthermore, the movable component is provided with a load-bearing plate, on which goods are placed. Attached Figure Description

[0027] like Figures 1-7 As shown, a sliding pallet support is used for placement inside a container. It includes a base frame 1 and a movable component 2 that slides on the base frame 1. The movable component 2 is provided with a load-bearing plate for placing goods. The base frame 1 has two track grooves 10 arranged with opposite openings. The movable component 2 has a sliding groove 13 corresponding to the track grooves 10. The sliding groove 13 covers the track grooves 10 from top to bottom. A roller 14 is rotatably mounted in the sliding groove 13. The roller 14 rolls within the track groove 10 to support the sliding of the movable component 2 on the base frame 1.

[0028] The base frame 1 is provided with a clearance channel 11 that connects to the track groove 10. The clearance channel 11 is connected to the sliding groove 13 on the moving part 2 so that the roller 14 rolls to the clearance channel 11, lifts the moving part 2, and the roller 14 moves out of the clearance channel 11, so that the base frame 1 and the moving part 2 are separated.

[0029] In this embodiment, a roller 14 is installed in the sliding groove 13 of the movable component 2. The roller 14 rolls in the track groove 10 of the base frame 1, which transforms the traditional sliding friction into rolling friction, greatly reducing the resistance. Even if the cargo is heavy, the movable component 2 can be pushed into the compartment along the track more easily by manual or mechanical pushing, avoiding pushing difficulties caused by excessive friction.

[0030] The two track grooves 10 of the base frame 1 are arranged with opposite openings to form a stable guiding structure. The sliding groove 13 of the moving part 2 covers the track groove 10 from top to bottom, so that the roller 14 always rolls in the track, avoiding deviation or jamming during movement, and ensuring the accuracy of the transport path. It is especially suitable for scenarios with limited internal space (such as narrow car bodies that need to be pushed in precisely).

[0031] First, heavy objects are placed directly onto the movable component 2 using forklifts, cranes, or other handling equipment, and then the movable component 2 is pushed into the compartment. This "one-time loading + sliding push-in" mode replaces the traditional "manual batch handling + in-compartment stacking" process, reducing the number of handling operations and manpower input.

[0032] Truck cargo compartments are typically narrow and deep, making it difficult to manually load heavy items directly into the interior. Sliding pallet supports, through an "external loading + rail sliding" method, transform the horizontal movement of heavy items into linear sliding along a track, eliminating the need for complex turning or lifting operations at the cargo compartment entrance. This is particularly suitable for trucks with deep cargo compartments.

[0033] In this embodiment, the structure of the sliding groove 13 "covering the track groove 10 from top to bottom" confines the roller 14 within the track, preventing the moving part 2 from detaching from the track due to bumps or uneven thrust. Even if the road surface is uneven during the pushing process, the roller 14 can maintain stable rolling, reducing the risk of goods tipping over.

[0034] The base frame 1 serves as the basic support structure, capable of withstanding the vertical pressure of heavy objects and preventing the moving parts 2 from deforming due to excessive load. For example, if the base frame 1 is made of welded steel, its load-bearing capacity can reach more than 2 tons, meeting the handling needs of most goods.

[0035] In this embodiment, as Figures 1-3 As shown, the movable part 2 is provided with a locking mechanism 3 for fixing the base frame 1 and the movable part 2 together. The locking mechanism 3 includes a sliding part 6 slidably arranged on the movable part 2, an L-shaped transmission part 7 hinged to the movable part 2, and an L-shaped pin 8 slidably arranged on the movable part 2. The middle part of the L-shaped transmission part 7 is hinged to the axis of the movable part 2 extending in the vertical direction. One end of the L-shaped transmission part 7 is hinged to the sliding part 6 extending in the vertical direction, and the other end is slidably connected to the L-shaped pin 8. Pulling the movable part 2 allows the L-shaped pin 8 to slide on the movable part 2, so that the L-shaped pin 8 passes through the movable part 2 and is inserted into the base frame 1, thereby fixing the base frame 1 and the movable part 2.

[0036] The movable part 2 on the base frame 1 may tend to shift horizontally. The locking mechanism 3 uses an L-shaped pin 8 to physically lock the movable part 2 and the base frame 1, forming a rigid whole. Specifically, when the sliding part 6 is pulled, the L-shaped transmission part 7 rotates around the central hinge point, causing the L-shaped pin 8 to slide laterally and insert into the preset hole in the base frame 1. This "pin + hole" locking method is like "a key inserted into a lock cylinder," which can effectively prevent the movable part 2 from sliding off the base frame 1.

[0037] The locking mechanism 3 adopts a linkage transmission design. The operator only needs to pull the sliding part 6 in a straight line to synchronously drive the pin action through the lever principle of the L-shaped transmission part 7, without the need for additional tools or complicated steps.

[0038] In this embodiment, the hinge point of the locking mechanism 3 adopts a wear-resistant bushing design, and the contact end between the L-shaped pin 8 and the base frame 1 is chamfered to reduce wear caused by long-term vibration. Even after long-term use, the fit clearance between the pin and the hole can still be maintained well.

[0039] When it is necessary to separate the base frame 1 from the movable part 2, simply push the slider 6 in the opposite direction to disengage the pin from the base frame 1, and the sliding state of the movable part 2 can be restored.

[0040] The sliding component 6 is equipped with a handle 4, which allows workers to easily control the fixing between the base frame 1 and the moving component 2 by hand. The handle 4 transforms the force application point of the locking operation into the grip force, which conforms to the ergonomic lever principle. This design allows female workers or operators with weaker physical strength to easily complete the locking, especially in scenarios such as cold chain logistics where gloves need to be worn frequently, thus avoiding slippage.

[0041] In this embodiment, the handle 4 is made of metal and wrapped with a non-slip rubber sleeve, which can withstand the mechanical stress of frequent pulling and reduce hand fatigue through rubber cushioning. The handle 4 and the slider 6 are detachably connected, so when the component is damaged, it can be replaced separately, and the repair cost is lower than replacing the entire slider 6.

[0042] A guide wheel 9 is rotatably mounted on the base frame 1 between the two track grooves 10. The guide wheel 9 is used to abut against the moving part 2 so that the moving part 2 can move between the guide wheel 9 and the track groove 10, and prevent the moving part 2 from deviating.

[0043] The guide wheels 9 are symmetrically installed between the two track grooves 10, with their wheel surfaces maintaining an elastic abutment gap of 0.5-1mm with the side of the moving part 2. When the moving part 2 is deviated by lateral thrust, the guide wheels 9 generate reverse resistance through rolling friction. This passive guiding mechanism does not require electric drive and can achieve automatic correction through mechanical contact alone.

[0044] The rolling friction coefficient of the guide wheel 9 is only 0.05 (the friction coefficient of the traditional slider is 0.3). When the worker pushes the moving part 2, there is no need to deliberately align it with the track groove 10. Even if there is a deviation in the thrust, the guide wheel 9 can "guide" the moving part 2 into the correct path through lateral support.

[0045] The guide wheel 9 is made of polyurethane-coated material with a Shore A hardness of 80A, which can provide sufficient lateral support and absorb the lateral impact force of the moving part 2 through elastic deformation. When the moving part 2 deviates slightly, the rolling contact of the guide wheel 9, rather than sliding friction, can reduce the wear on the side of the track groove 10.

[0046] The guide wheel 9 and the roller 14 in the track groove 10 form a three-dimensional guide structure of "upper and lower support + lateral constraint": the roller 14 bears the load in the vertical direction, and the guide wheel 9 resists the offset torque in the horizontal direction.

[0047] In this embodiment, a stop wheel 12 is provided at the end of the track groove 10. The stop wheel 12 and the clearance channel 11 are located at the same end to prevent the moving part 2 from sliding directly out of the track groove 10. When the moving part 2 slides to the end of the track groove 10, the stop wheel 12 achieves buffer braking through rolling friction rather than rigid collision.

[0048] When the movable part 2 is pushed until the stop wheel 12 abuts, the roller 14 is aligned with the clearance channel 11 of the base frame 1. At this point, the worker does not need to make any additional adjustments and can directly lift the movable part 2 to move the roller 14 out of the clearance channel 11. This "push-to-stop, stop-to-remove" mechanism is similar to the paper positioner of a printer. When loading and unloading at night or in the dimly lit interior of the compartment, the worker can judge whether the movable part 2 has reached the correct position by the feel or sound of the stop wheel 12 hitting the stop wheel, reducing repeated adjustments caused by visual errors.

[0049] In this embodiment, the stop wheel 12 is made of nylon with glass fiber (Shore hardness 90A), and its elastic buffering performance can reduce the impact force of the moving part 2.

[0050] The limiting function of the stop wheel 12 works in conjunction with the separation mechanism of the clearance channel 11: when the moving part 2 is fixed in place by the stop wheel 12, the roller 14 is exactly below the clearance channel 11. This "positioning-separation" linkage design avoids the problem of the roller 14 getting stuck because the moving part 2 is not fully in place and is lifted up.

[0051] A handle 5 is fixed to the movable component 2, and the handle 5 and the grip 4 are in the same position. The worker can directly pull the movable component 2 on the base frame 1 by using the handle 5. The integrated design of the handle 5 and the grip 4 in the same axial position eliminates the need for the worker to change hand grips throughout the loading and unloading process. For example, during the cargo loading stage, the worker can first use the grip 4 to separate the movable component 2 from the base frame 1. After the cargo is in place, the worker can directly push the movable component 2 along the track groove 10 by using the handle 5 in the same position. After the movable component 2 is in place, the worker can push the grip 4 to fix the movable component 2 and the base frame 1.

[0052] The working process of this utility model is as follows:

[0053] In use, the base frame 1 can be placed in the box first, and then the moving part 2 can be moved through the clearance channel 11 so that the roller 14 enters the track groove 10, thereby allowing the moving part 2 to be installed on the base frame 1. The goods are placed on the moving part 2 by the handling equipment, and then the moving part 2 is pushed to move and fix the base frame 1 and the moving part 2, thereby completing the handling of the goods.

[0054] During unloading, the base frame 1 is separated from the moving part 2 by using handle 4. The moving part 2 is then pulled to move the goods inside the compartment to the outside of the compartment. The goods can then be removed by handling equipment.
