Description

Technical Field

[0001] The invention belongs to the technical field of gas storage or distribution containers, and in particular relates to a container used in the transportation process of steel cylinders. Background Art

[0002] Steel high-pressure gas cylinders (also known as cylinders) are widely used in the transportation of industrial gases. After being filled with sufficient liquid gas, they are then transported in containers. Cylinders are typically very heavy. For example, an 80L cylinder can weigh around 100kg, making it difficult for ordinary workers to lift such a heavy weight. However, due to space constraints, manual transport, such as elevators or transfer vehicles, is often used during transportation, as mechanical replacements are not feasible. However, since cylinders are generally cylindrical in structure, workers typically transport them by rotating their bottoms along a predetermined route, which is labor-saving. However, when transporting cylinders to a designated container, workers still need to lift the cylinders to a certain height to load them into the container due to the height of the container frame. For example, Publication No. CN208587735U discloses a mobile container for cylinders. The frame structure includes a base, left frame, right frame, and rear frame. The base is relatively high, so when a cylinder is transported near the base, it must be lifted and transferred to the base, which is very labor-intensive. Therefore, how to transfer the cylinders to nearby containers for transportation without lifting the cylinders during the entire process is an urgent problem that needs to be solved. Summary of the Invention

[0003] The purpose of the present invention is to provide a container for transporting steel cylinders, which not only has the ability to containerize and transfer steel cylinders, but also has an inclined plate set at the front end of the frame supporting the steel cylinders, so that when workers transport the steel cylinders to the frame, they can continue to roll the steel cylinders to the frame, saving time and effort.

[0004] The technical solution adopted by the present invention to solve the above-mentioned problem is: a container for transporting steel cylinders, including a frame for supporting steel cylinders, universal wheels arranged at the lower end of the frame and used for transporting steel cylinders, a base plate unit on which the universal wheels are installed, and an inclined plate unit arranged at the front end of the base plate unit and used to support the steel cylinders for rolling transportation onto the frame.

[0005] A further preferred technical solution is that: the inclined plate unit includes an inclined plate and an adjustment column arranged at the upper end of the inclined plate; the base plate unit includes a base plate, an inclined plate groove arranged at the lower end of the base plate and used to install the inclined plate, and a horizontal slide groove and a vertical slide groove connected to the inclined plate groove and used to install the adjustment column, and a support block unit installed at the junction of the horizontal slide groove and the vertical slide groove and used for limiting the engagement when the adjustment column moves to the vertical slide groove.

[0006] A further preferred technical solution is that: the base plate unit also includes a bracket groove for installing the bracket unit; the bracket unit includes a bracket installed in the bracket groove, and a moving rod arranged on the side of the bracket and passing through the transverse sliding groove.

[0007] A further preferred technical solution is that the support block unit further includes a support block return spring disposed in the support block groove and used for pushing the support block outward.

[0008] A further preferred technical solution is that: the base plate unit also includes a trigger block groove arranged horizontally and connected to the vertical slide groove, and a blocking block groove arranged vertically and connected to the trigger block groove; a trigger block unit is provided in the trigger block groove, and a blocking block unit is provided in the blocking block groove, and when the trigger block unit slides into the trigger block groove, the blocking block unit is pushed upward to support the cylinder.

[0009] A further preferred technical solution is that: the trigger block unit includes a sliding block arranged in the trigger block groove, a lower inclined block arranged on the sliding block, and a sliding return spring arranged in the trigger block groove and used to push the sliding block outward; the blocking block unit includes a blocking block arranged in the blocking block groove, and an upper inclined block arranged at the lower end of the blocking block and against the lower inclined block.

[0010] A further preferred technical solution is that the bottom plate unit further includes a limit baffle provided at the notch end of the trigger block slot and used to block the lower inclined block.

[0011] A further preferred technical solution is that the blocking block unit further includes a blocking block return spring for pushing the blocking block inward.

[0012] A further preferred technical solution is that the trigger block unit further includes a trigger block provided at the outer end of the sliding block and used to abut against the adjustment column.

[0013] A high-purity body transportation system includes the above-mentioned container used in the cylinder transportation process.

[0014] The advantages of the present invention are:

[0015] First, a slanted plate is set at the front end of the frame supporting the cylinder, so that when the worker transports the cylinder to the frame, he can continue to roll the cylinder to the frame.

[0016] Second, the inclined plate is movably arranged at the front end of the frame. After the cylinder is transported, the inclined plate can be stored at the bottom side of the frame, which reduces the overall footprint of the frame and makes it easier to carry the inclined plate.

[0017] Third, the inclined plate can be lifted off the ground after being stored, so that the cylinder will not come into contact with the ground during transportation, which facilitates the transportation process;

[0018] Fourth, after the inclined plate is stored, the cylinder is stored by default. The action of storing the inclined plate can cause the blocking plate used to fix the position of the cylinder to pop out, reducing the risk of the cylinder falling off the frame during transportation.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the accompanying drawings.

[0037] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.

[0038] Example: The following will refer to Figure 1-3 To describe the container according to the embodiment of the present disclosure, Figure 1 This is a schematic diagram of the process of transporting the cylinder to the frame by rotating the inclined plate. Figure 2 for Figure 1 The middle cylinder has been transported to the frame and the inclined plate has been stored. Figure 3 Based on Figure 2 Schematic diagram of the viewing frame from the center-left direction.

[0039] like Figure 1As shown, the container includes a frame 1 for supporting the cylinder A, a universal wheel 2 provided at the lower end of the frame 1 and used for transporting the cylinder A, a base unit 3 on which the universal wheel 2 is mounted, and an inclined plate unit 4 provided at the front end of the base unit 3 and used for supporting the cylinder A to be rolled onto the frame 1. The inclined plate unit 4 is placed at the front end of the base unit 3, and the bottom surface is flush with the universal wheel 2, both of which are in contact with the ground. The inclined plate unit 4 has an inclined surface facing the cylinder side, which allows the cylinder to be rotated and transported to the frame 1, and the slope of the inclined surface is relatively gentle. Generally, the acute angle formed by the inclined surface and the horizontal plane should not exceed 20 degrees, so as to facilitate the transportation process of the workers. The frame 1 includes a frame body 101, and a chain 102 provided on the frame body 101 and used to fix the cylinder, see Figure 3 After the last cylinder is transported to the frame body 101, a chain 102 is placed over the opening of the frame body 101 to provide a safety feature. Even if cylinder A tilts during transport, it will not fall out of the frame body 101. The frame body 101 itself protects cylinder A from other directions. It should be noted that while the frame body 101 shown in the figure is rectangular, any frame structure that can accommodate and secure cylinder A can serve as the frame body 101. The base plate unit 3 does not directly support cylinder A, but in some embodiments, it can cooperate with the frame body 101 to support cylinder A.

[0040] In particular, when the loading process of the cylinder A is completed and the transportation begins, in order to prevent the inclined plate unit 4 from rubbing against the ground and affecting the transportation, Figure 2 The inclined plate unit 4 can be stored inward and lifted up to keep away from the ground and placed under the frame body 101, without causing friction with the ground and without protruding outward to affect the transportation process.

[0041] See below Figure 4-8 To describe the working process of storing the inclined plate unit 4. The inclined plate unit 4 includes an inclined plate 401 and an adjustment column 402 arranged at the upper end of the inclined plate 401; the bottom plate unit 3 includes a bottom plate 301, an inclined plate groove 302 arranged at the lower end of the bottom plate 301 and used to install the inclined plate 401, and a horizontal slide 303 and a vertical slide 304 connected to the inclined plate groove 302 and used to install the adjustment column 402, and a support block unit 5 installed at the junction of the horizontal slide 303 and the vertical slide 304 and used to limit the engagement when the adjustment column 402 moves to the vertical slide 304. During installation, the inclined plate 401 is installed into the inclined plate groove 302 from bottom to top, and then the adjustment column 402 is installed into the horizontal slide 303. For the storage process, see Figure 6-8The adjusting column 402 moves inward along the horizontal slide groove 303, and then pushes it aside after passing the supporting block unit 5. Finally, the adjusting column 402 is lifted and the supporting block unit 5 that was previously pushed aside is placed underneath it, thereby realizing the function of "storing and lifting" the inclined plate 401. Figure 9-11 The process of storing the inclined plate 401 from a top view is shown.

[0042] See below Figure 4-8 Combine Figure 14 To understand the functional implementation of the support unit 5, the base unit 3 also includes a support slot 305 for mounting the support unit 5; the support unit 5 includes a support block 501 mounted in the support slot 305, and a movable rod 502 disposed on the side of the support block 501 and extending through the transverse slot 303. When the support block 501 is lifted by the adjustment column 402, it moves inward along the support slot 305. When the adjustment column 402 moves up to the vertical slot 304, the support block 501 is freed from external obstruction and can be manually moved outward to move the movable rod 502 below the adjustment column 402, thereby supporting the adjustment column 402.

[0043] If the inclined plate 401 needs to be used again, the moving rod 502 can be used to move the support block 501 to the support block groove 305. The adjusting column 402 loses the support function of the support block 501 below and is driven by the gravity of the inclined plate 401 to fall into the horizontal slide groove 303. Then, it slides outward so that the inclined plate 401 reaches the position as shown in FIG. Figure 1 Position shown.

[0044] Furthermore, in a preferred embodiment, the support block unit 5 further includes a support block return spring 503 disposed in the support block slot 305 and configured to push the support block 501 outward. This allows the support block return spring 503 to move the support block 501 outward, eliminating the need for manual use of the moving rod 502 to move the support block 501 below the adjustment column 402 in the aforementioned steps. Another advantage of the support block return spring 503 is that, during transportation, the container as a whole may vibrate, which can cause the support block 501 to slide inward, gradually losing its support for the adjustment column 402 and causing the inclined plate 401 to fall and hit the ground. The support block return spring 503 counteracts this inward sliding of the support block 501, providing a safety feature.

[0045] refer to Figure 2-3The bottom plate unit 3 further includes a trigger block slot 306 disposed transversely and communicating with the vertical slide slot 304, and a blocking block slot 307 disposed vertically and communicating with the trigger block slot 306; a trigger block unit 6 is disposed in the trigger block slot 306, and a blocking block unit 7 is disposed in the blocking block slot 307. When the trigger block unit 6 slides into the trigger block slot 306, the blocking block unit 7 is pushed upward to resist the cylinder A. When the inclined plate unit 4 is retracted, the blocking block unit 7 is driven to protrude outward to cooperate with the frame 1 from below to fix the cylinder. Figure 6-8 The blocking block unit 7 is driven by the inward movement of the trigger block unit 6 to protrude outward.

[0046] refer to Figure 12-13 and 15-16, the trigger block unit 6 includes a sliding block 601 arranged in the trigger block groove 306, a lower inclined block 602 arranged on the sliding block 601, and a sliding return spring 603 arranged in the trigger block groove 306 and used to push the sliding block 601 outward; the blocking block unit 7 includes a blocking block 701 arranged in the blocking block groove 307, and an upper inclined block 702 arranged at the lower end of the blocking block 701 and against the lower inclined block 602. When the sliding block 601 slides inward due to the squeezing force from the adjusting column 402, the lower inclined block 602 also slides inward. Since the lower inclined block 602 and the upper inclined block 702 are provided with inclined surfaces relative to each other, and the upper inclined block 702 can only move up and down due to the restriction that the blocking block 701 is installed in the blocking block groove 307, when the lower inclined block 602 slides inward, the upper inclined block 702 slides upward along the inclined surface of the lower inclined block 602, thereby pushing the blocking block 701 out of the blocking block groove 307.

[0047] In a preferred embodiment, the bottom plate unit 3 further includes a limit stopper 308 disposed at the notch end of the trigger block slot 306 and used to block the lower inclined block 602. Figure 12 The limit baffle 308 blocks the side straight surface of the lower inclined block 602 so that the sliding block 601 will not be removed from the trigger block groove 306 during movement, and the limit baffle 308 reduces the width of the notch of the trigger block groove 306 to just match the height of the sliding block 601, so that the sliding block 601 moves in a straight line during movement without up and down turbulence.

[0048] In a preferred embodiment, the block unit 7 further includes a block return spring 703 for pushing the block 701 inward. When the sliding block 601 is reset by the action of the return spring 603, the block return spring 703 is sleeved onto the block 701, with its upper end engaging the spring mounting block at the notch of the block slot 307 and its lower end pressing against the protruding block on the side of the block 701, allowing the block 701 to move downward and retract, without affecting the subsequent unloading and installation of the cylinders into the container. It should be noted that the block return spring 703 is not a necessary component, but rather an auxiliary device that facilitates the reset of the block 701.

[0049] In a preferred embodiment, the trigger block unit 6 further includes a trigger block 604 disposed at the outer end of the sliding block 601 and configured to abut against the adjustment post 402. The structure of the trigger block 604 is similar to that of the upper inclined block 702, except that its inclined surface faces the adjustment post 402 and its height is consistent with that of the sliding block 601. Thus, when the adjustment post 402 rises to the vertical slot 304, it can lift the trigger block 604, thereby driving the sliding block 601 to slide inward. It should be noted that the trigger block 604 is not a necessary component, but rather an auxiliary device that facilitates the inward sliding of the sliding block 601.

[0050] Based on the above content, the specific usage of the container grid is as follows:

[0051] 1. When used to transport cylinders to the container

[0052] First, operate the moving rod 502 to retract the bracket 501 into the bracket slot 305, so that the adjustment column 402 is lowered, and then move the adjustment column 402 outward along the horizontal slide groove 303 to move the inclined plate 401 to the entrance of the frame body 101, and then transport the cylinder.

[0053] 2. When used to transport cylinders

[0054] The operation adjustment column 402 moves inward along the horizontal sliding groove 303 and then is lifted up and moved into the vertical sliding groove 304 to complete the storage function of the inclined plate 401.

[0055] In addition, the same or similar reference numerals are used in the drawings and description to refer to the same or similar parts or steps whenever possible.
