Description

Technical Field

[0001] This utility model relates to the field of warehousing and logistics technology, specifically to a suspended bottom-opening transfer box. Background Technology

[0002] In the logistics and warehousing sector, transfer containers need to be adapted to automated conveying systems to achieve efficient loading and unloading. Traditional transfer containers mostly adopt side-opening or top-discharge designs, which have problems such as low space utilization, incomplete unloading, and excessive manual intervention. Therefore, suspended conveyor transfer containers are widely used due to their advantages such as high space utilization and flexible conveying paths.

[0003] Typically, suspended conveyor transfer boxes need to meet two core requirements: ① Automated unloading at fixed points, i.e., automatic bottom opening and unloading at specific locations on the conveyor line; ② Dynamic operational stability to adapt to vibrations and start-stop impacts during suspended conveying, preventing accidental opening or tipping. However, current suspended conveyor transfer boxes have the following drawbacks: ① Regarding the unloading mechanism, the mainstream electric push rod driven bottom opening scheme suffers from high circuit failure rates and high maintenance costs; ② Purely mechanical locking structures (such as spring pins) are prone to accidental disengagement under conveying vibrations (leading to material spillage, and are difficult to automate).

[0004] Therefore, there is an urgent need for a transfer box that is compatible with suspended conveyors, has a stable self-locking mechanism, and features a bottom-opening structure triggered by external force, so as to achieve automated unloading at fixed points and ensure operational safety. Utility Model Content

[0005] In order to overcome the above-mentioned defects of existing suspended conveyor transfer boxes, this utility model provides a suspended bottom-opening transfer box.

[0006] The technical solution adopted by this utility model is as follows: A suspended bottom-opening transfer box includes: a box body with an open top, and lifting lugs on both sides of the box body; two double-opening bottom doors, symmetrically connected to the bottom of the box body by hinges; a gas spring with the piston rod facing upward and the cylinder facing downward, vertically fixed to the box body; an upper pull rod and two lower pull rods, the top of the upper pull rod is provided with a horizontally extending operating part, the upper end of the upper pull rod is connected to the end of the piston rod, the lower end of the upper pull rod is symmetrically hinged to the upper ends of the two lower pull rods, and the lower ends of the lower pull rods are respectively connected to the two bottom doors, wherein the two lower pull rods and the upper pull rod form a Y-shaped linkage structure, which synchronously keeps the two bottom doors in the closed position under the action of the gas spring, or synchronously opens the two bottom doors to the open position when the operating part is pressed down by an external pressing member.

[0007] Preferably, the upper and lower ends of the cylinder are fixed to the side wall of the box body by U-shaped buckles and fasteners, and the U-shaped buckles are installed on the outer surface of the box body.

[0008] Preferably, the operating part is a horizontally bent metal plate or a welded horizontal plate, the height of which matches the stroke of the external pressing member.

[0009] Preferably, the top or side wall of the housing is provided with an anti-tipping bracket, which is located on the opposite side of the gas spring and abuts against the external balance member to balance the overturning torque generated when the external pressing member acts on the operating part.

[0010] Preferably, the abutment end of the anti-tipping bracket is provided with a buffer pad made of polyurethane or nylon.

[0011] Preferably, the housing is a flat basket structure, the gas spring and the upper pull rod are located in the middle of the narrow side wall of the housing, and the anti-tipping bracket is arranged on the top or side wall of the housing on the other side of the gas spring.

[0012] Preferably, the number of anti-tipping brackets is two sets, symmetrically arranged on both sides of the top of the box to form a double-point support structure.

[0013] Preferably, the wide sidewalls of the box body have a mesh-like perforated structure.

[0014] Preferably, the external pressing component is one of a pole mechanism, a cylinder, or a hydraulic cylinder, with its driving end vertically aligned with the operating part.

[0015] This utility model has the following beneficial effects:

[0016] 1. Stable self-locking and vibration resistance: The gas spring piston rod is installed upward, providing a continuous upward preload. The Y-shaped linkage structure composed of the upper pull rod and two lower pull rods keeps the two bottom cover doors always tending to be closed, effectively resisting the vibration and impact during suspended conveying, and completely solving the problem of material spillage caused by the accidental dislodgement of the traditional spring pin.

[0017] 2. High-efficiency automated unloading: External pressing components such as pole mechanism / cylinder press down vertically on the operating part, and the linkage pull rod opens the double bottom cover door simultaneously, realizing fixed-point and fast unloading without manual intervention, thus improving unloading efficiency;

[0018] 3. Anti-tipping stability: The anti-tipping bracket, together with the buffer pad, resists the external balance component, offsets the overturning moment when the operating part is pressed down, and ensures the balance of the box during dynamic conveying and unloading, especially suitable for the suspension conditions of flat basket boxes;

[0019] 4. Low cost: Gas springs replace electric push rods or cylinders as the status holding components, eliminating the need for circuits or air lines to move the housing. The external installation of the U-shaped buckle facilitates gas spring maintenance, and the mesh-hole housing reduces its weight and extends its service life. Attached Figure Description

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] In the embodiments, such as Figures 1-3 As shown, a suspended bottom-opening transfer box includes: a box body 1 with an open top, and lifting lugs 1.1 on both sides of the box body; two split bottom doors 2, symmetrically connected to the bottom of the box body 1 by hinges 3; a gas spring 4, with piston rod 4.1 facing upward and cylinder 4.2 facing downward, vertically fixed to the box body 1; an upper pull rod 5 and two lower pull rods 6, the top of the upper pull rod 5 having a horizontally extending operating part 5.1, the upper end of the upper pull rod 5 being connected to the end of the piston rod 4.1, and the lower end of the upper pull rod 5 being symmetrically hinged to the upper ends of the two lower pull rods 6, the lower ends of the lower pull rods 6 being respectively connected to the two bottom doors 2, wherein the two lower pull rods 6 and the upper pull rod 5 form a Y-shaped linkage structure, which synchronously keeps the two bottom doors 2 in the closed position under the action of the gas spring 4, or synchronously opens the two bottom doors 2 when the operating part 5.1 is pressed down by the external pressing part. In this embodiment, the gas spring 4 is installed facing upwards to provide a continuous upward preload. Through the Y-shaped linkage structure (upper pull rod 5 and lower pull rod 6), the two bottom cover doors 2 are always inclined to close, completely solving the problem of accidental opening caused by conveying vibration. When the external pressing component presses down vertically on the operating part 5.1, the Y-shaped linkage structure simultaneously pulls the double bottom cover doors 2 to open, realizing fixed-point automated unloading without manual intervention.

[0034] In the embodiments, such as Figures 1-2 As shown, the upper and lower ends of the cylinder 4.2 are fixed to the side wall of the housing 1 by U-shaped buckles 7 and fasteners, respectively. The U-shaped buckles 7 are installed on the outer surface of the housing 1. The U-shaped buckles 7 are externally installed on the surface of the housing 1, which facilitates the quick disassembly and maintenance of the gas spring 4, while avoiding interference with the internal structure of the housing.

[0035] In the embodiments, such as Figures 1-2 As shown, the operating unit 5.1 is a horizontally bent metal plate or a welded horizontal plate, the height of which matches the stroke of the external pressing component. The operating unit 5.1 adopts a horizontal metal plate / plate structure to precisely match the stroke of the external pressing component, ensuring that the downward pressure is transmitted vertically and avoiding mechanism jamming.

[0036] In the embodiments, such as Figures 1-2 As shown, the top or side wall of the housing 1 is provided with an anti-tipping bracket 8. The anti-tipping bracket 8 is located on the opposite side of the gas spring 4 and abuts against the external balance component to balance the overturning moment generated when the external pressing component acts on the operating part 5.1. The anti-tipping bracket 8 abuts against the external balance component and actively counteracts the overturning moment generated by the downward pressure during unloading, ensuring the dynamic stability of the housing 1.

[0037] In the embodiments, such as Figures 1-2 As shown, the abutment end of the anti-tipping bracket 8 is provided with a buffer pad 9 made of polyurethane or nylon. The polyurethane / nylon buffer pad 9 absorbs the impact vibration between the external balancing component and the bracket 8, reduces noise, and prevents damage from rigid contact.

[0038] In the embodiments, such as Figures 1-2 As shown, the housing 1 has a flat basket structure. The gas spring 4 and the upper pull rod 5 are located in the middle of the narrow side wall of the housing. The anti-tipping bracket 8 is arranged on the top or side wall of the housing 1 on the other side opposite to the gas spring 4. The gas spring 4 and the anti-tipping bracket 8 are placed on both sides of the narrow side of the housing, forming a force couple balance layout, which is adapted to the suspension center of gravity characteristics of the flat basket housing.

[0039] In the embodiments, such as Figures 1-2 As shown, there are two sets of anti-tipping supports 8, symmetrically arranged on both sides of the top of the box, forming a double-point support structure. The double anti-tipping supports 8 provide symmetrical support, dispersing the overturning moment and enhancing the torsional resistance of the box 1, thus avoiding the risk of single-point support failure.

[0040] In the embodiments, such as Figures 1-2 As shown, the wide sidewalls of the container 1 have a mesh-like perforated structure. This mesh-like perforated structure reduces the container's weight by more than 30%, while also improving material visibility and residue cleaning efficiency.

[0041] In the embodiments, such as Figures 1-2As shown, the external pressing component is one of a pole mechanism, a pneumatic cylinder, or a hydraulic cylinder, with its drive end vertically aligned with the operating unit 5.1. The standardized external pressing component (pole / cylinder / hydraulic cylinder) vertically drives the operating unit 5.1, directly compatible with automated production line execution units, reducing system integration costs.

[0042] Obviously, the above embodiments of this utility model are merely examples for illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Other obvious variations or modifications derived from the essential spirit of the present utility model still fall within the protection scope of the present utility model.
