Description

Technical Field

[0001] This application relates to the field of loading rack technology, and specifically discloses a mobile gas cylinder storage and retrieval rack. Background Technology

[0002] In industrial production, construction and other work scenarios, gas cylinders (such as oxygen cylinders, acetylene cylinders, etc.) are commonly used equipment. However, there is often a large distance between the work site and the fixed gas cylinder storage point, which often leads to difficulties in transporting gas cylinders.

[0003] Traditional methods for transferring gas cylinders between work sites and fixed storage locations in the industry mainly rely on the following: 1. Manual handling: Workers manually move the gas cylinders. This method is simple and does not require tools, but it can only move 1-2 cylinders at a time, making it suitable only for small-scale operations. When the daily usage is large (e.g., 20 cylinders per day), the low efficiency of handling will delay the work progress, resulting in more harm than good. 2. Simple trolley transportation: Basic trolleys are used to transport gas cylinders, allowing multiple cylinders (approximately 5-10 cylinders) to be moved at once. However, the trolleys lack a dedicated fixing structure, making the cylinders prone to shaking or tipping over during transportation.

[0004] To address the problems inherent in traditional gas cylinder transport methods, existing technologies have developed trolleys specifically designed for gas cylinder transport. For example, patent application number CN202020755548.8 discloses a gas cylinder transport trolley. This trolley features a vertical plate fixed to its support plate. One side of the vertical plate has a handle, while the other side incorporates a stabilizing mechanism, long strips, clamps, grooves, compression springs, rubber blocks, and other structures to secure the gas cylinder during transport, preventing it from easily shaking or tipping over. This improves transport efficiency and ensures safe transport of the gas cylinder.

[0005] While the existing methods described above can achieve safe transportation, key drawbacks remain unresolved: the transfer trolleys in current technologies can only hold a limited number of gas cylinders, making it impossible to transport a sufficient quantity at once, thus restricting the continuity of gas cylinder transfer operations and increasing labor costs. Therefore, the industry urgently needs a comprehensive solution for gas cylinder transfer. Summary of the Invention

[0006] The purpose of this invention is to provide a mobile gas cylinder storage and retrieval rack to solve the technical problems mentioned above, such as the inability of the prior art to transport a sufficient number of cylinders at one time, which limits the continuity of gas cylinder transfer operations and increases labor costs.

[0007] To solve the above problems, the technical solution adopted by the present invention is as follows: a mobile gas cylinder storage and retrieval rack, comprising a moving mechanism with casters mounted on the bottom and a gas cylinder fixing device for circumferentially fixing the gas cylinder, characterized in that: the moving mechanism is provided with several layers of storage racks in the vertical direction, each layer of the storage rack is provided with a retrieval auxiliary mechanism, the retrieval auxiliary mechanism includes a tray covering the upper surface of the storage rack, one side of the tray is rotatably connected to the storage rack by a bearing, and on the other side of the relative rotatable connection, a lifting cylinder is provided between the storage rack and the tray to lift the tray.

[0008] The beneficial effects of this implementation plan are as follows: 1. Existing transfer trolleys have only a single-layer structure, limiting the number of gas cylinders they can hold and making it impossible to transport a sufficient number at once. This restricts the continuity of gas cylinder transfer operations and increases labor costs. Compared to existing technologies, this utility model features a multi-layer storage rack, capable of transporting and storing dozens of gas cylinders at once, significantly reducing the number of times operators need to move them back and forth, saving considerable time. During transportation, the gas cylinder fixing device ensures cylinder stability, reducing safety risks. When stored at the work site, the layered design and retrieval structure facilitate sequential cylinder retrieval, improving operational efficiency. After implementing this technical solution, the time spent by operators moving gas cylinders back and forth can be reduced by approximately 70%, significantly improving operational efficiency. The incidence of cylinder tipping accidents during transportation and storage is almost zero, effectively eliminating safety hazards caused by sun exposure. The layered and orderly storage and convenient retrieval method make gas cylinder management more standardized and further optimize the work process.

[0009] 2. Existing transfer trolleys have only a single-layer structure, limiting the number of gas cylinders they can hold and making it impossible to transport a sufficient quantity at once. To transport more cylinders, a multi-layer structure is needed. However, this multi-layer structure leads to two problems: 1. With a multi-layer structure and cylinders placed vertically on each shelf, the height of the cylinders results in large gaps between shelves. The height of the second shelf is higher than a worker's shoulder, making it difficult to retrieve cylinders from the second shelf; ladders or tools on the platform are required. 2. If the cylinders are laid horizontally, the spacing between shelves is greatly reduced. However, the cylinders are still tall, and when laid down, they extend too far on the shelves. The small spacing between shelves makes it difficult for workers to enter the shelves, requiring them to drag the cylinders out from the rear, which is very inconvenient. This application provides a retrieval auxiliary mechanism that tilts the pallet, allowing the cylinders to slide out under gravity, thus making retrieval much easier.

[0010] Furthermore, the gas cylinder fixing device is located on both sides of the storage rack and includes an arc-shaped strap, which has a buckle to enable quick locking and releasing of the strap.

[0011] Furthermore, it also includes protective canopies to shield the external environment.

[0012] Furthermore, the pallet is provided with a gas cylinder storage tank, the inner surface of the gas cylinder storage tank is provided with a U-shaped groove, and a card plate is provided in the U-shaped groove to support the bottom of the gas cylinder.

[0013] Furthermore, the omnidirectional wheel of the moving mechanism is equipped with a double brake pad locking structure.

[0014] Furthermore, the end of the piston rod of the lifting cylinder is provided with a ball cup, and the piston rod is hinged to a hinge ball using the ball cup, and the hinge ball is fixedly connected to a support plate. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model. Figure 2 This is a schematic diagram of the structure of the auxiliary mechanism for picking up materials according to this utility model. Detailed Implementation

[0016] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: bottom frame 11, caster wheel 12, push handle 13, storage rack 2, sunshade canvas 3, retrieval auxiliary mechanism 4, lifting cylinder 41, piston rod 411, hinge ball 412, support plate 413, rotating shaft 42, pallet 43, gas cylinder storage tank 431, and clamping plate 432.

[0017] Implementation, for example, attached Figure 1-2 As shown: A mobile gas cylinder storage and retrieval rack consists of five core modules: The moving mechanism 1 has a bottom frame 11 welded from aluminum alloy square tubes. A support plate is set below the bottom frame, and nine heavy-duty casters 12 with uniform load-bearing capacity are installed under the support plate. The wheel body of the casters 12 can be made of polyurethane-coated steel core, and the static load of a single wheel is 150kg. The axle of the casters 12 is connected to double brake pads. All brake pads can be controlled to move synchronously through the linkage steel cable by pushing the operating lever on the handle 13, and the rear wheel displacement is locked. Its control structure and logic are the existing bicycle brake structure.

[0018] The multi-level storage structure includes storage racks 2 for supporting gas cylinders in layers. The storage racks 2 are welded from aluminum alloy square tubing. Vertical square tubing is installed along the bottom frame 11 to form a multi-level structure, resulting in three storage racks 2 including the bottom frame 11. Each storage rack 2 is equipped with a retrieval auxiliary mechanism 4, and the retrieval auxiliary mechanisms 4 on each storage rack 2 have the same structure and the same connection relationship with the storage rack 2. Figure 1Only the retrieval auxiliary mechanism 4 on the bottommost storage shelf 2 is shown in the image.

[0019] In this embodiment, Figure 1 The auxiliary mechanism 4 for retrieving gas cylinders on the lowest storage rack 2 is described below, with the direction of the push handle 13 representing the right side of the gas cylinder storage and retrieval rack in this embodiment. The auxiliary mechanism 4 includes three main components: a lifting cylinder 41, a rotating shaft 42, and a tray 43. The rotating shaft 42 and the tray 43 are an integral structure; the tray 43 covers the upper surface of the storage rack 2 and has a smaller area than the storage rack 2. The rotating shaft 42 is located in front of the tray 43 and extends from both ends of the tray 43, forming a rotatable connection with the vertical square tube on the storage rack 2 using bearings. Therefore, the tray 43 covering the storage rack 2 can be rotated to separate from the upper surface of the storage rack 2, forming an inclined surface that is higher at the rear and lower at the front. A gas cylinder storage slot 431 is formed on the surface of the pallet 43. The gas cylinder storage slot 431 prevents the gas cylinder from rolling on the pallet 43 when it is placed on it. A retaining plate 432 is also provided on the front side of the gas cylinder storage slot 431 to support the bottom of the gas cylinder when the pallet 43 is tilted, preventing the gas cylinder from slipping. A U-shaped groove is provided on the inner surface of the gas cylinder storage slot 431. The size of the U-shaped groove is the same as that of the retaining plate 432. The retaining plate 432 is limited by being inserted into the U-shaped groove. The storage rack 2 is provided with a mounting plate, and a lifting cylinder 41 is installed on the mounting plate. The connection structure between the lifting cylinder 41 and the pallet 43 is as follows. Figure 2 As shown, the piston rod 411 of the lifting cylinder 41 is located below the pallet 43. A ball cup is provided at its upper end, and a hinged ball 412 is hinged to the piston rod 411 via the ball cup. The hinged ball 412 can rotate within the ball cup but cannot disengage from it. A support plate 413 is fixedly connected to the upper end of the hinged ball 412 via a connecting rod. The support plate 413 contacts the lower surface of the pallet 43 but does not form a connection; the support plate 413 can slide below the pallet 43. The auxiliary mechanism 4 can use the piston rod 411 of the lifting cylinder 41 to lift or lower the pallet 43, causing the pallet 43 to rotate on the storage rack 2, forming an inclined surface.

[0020] Gas cylinder fixing device: Arc-shaped straps are provided on the storage racks on the left and right sides of the gas cylinder storage tank 431 of the pallet 43. The arc-shaped straps are made of nylon base cloth + natural rubber composite laminate (tensile strength ≥2000N); the ends are provided with ITW Nexus type quick buckles.

[0021] Protective canopy: An aluminum alloy round tube bracket is connected to the upper end of the top storage rack 2. A sunshade canvas 3 is installed on the aluminum alloy round tube bracket. The sunshade canvas 3 can be made of PVC coated Oxford cloth (UPF50+). The edges of the sunshade canvas 3 are fixed to the aluminum alloy round tube bracket with Velcro.

[0022] Wheel installation: Insert the casters into the mounting brackets of the bottom frame and tighten them with M12 high-strength bolts. Lay the linkage cable inside the cavity of the square tube, connecting one end to the operating lever on the push handle 13 and the other end to the brake pad of the caster 12. Adjust the preload of the cable. When the operating lever moves laterally by 30°, the brake pad should be in full contact with the wheel surface, applying pressure to complete the braking.

[0023] Gas cylinder securing procedure: Insert the gas cylinder vertically into the limiting slot, ensuring that the bottom contact surface is ≥90%; tighten the strap: pull the arc-shaped strap around the gas cylinder, and the tension gauge shows that the pre-tightening force reaches 60±10N; fasten the quick buckle until a clear "click" is heard, at which point the strap is secured to the cylinder.

[0024] The above descriptions are merely embodiments of the present invention, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
