Description

Technical Field

[0001] This utility model relates to the field of railway transportation technology, and in particular to a cylinder crane for high-speed rail tank cars. Background Technology

[0002] With the rapid development of high-speed rail networks and dedicated freight lines, railway transport capacity has been significantly enhanced. In terms of railway tank car technology, especially the design and application of airlock cranes, this has become a crucial element in ensuring transport safety and efficiency.

[0003] Referring to existing patent publication number CN202106986U, a railway tank car air cylinder crane includes an L-shaped support for suspending the air cylinder. This utility model's railway tank car air cylinder crane uses a suspended installation method, meaning the weight of the air cylinder is entirely borne by the suspended air cylinder crane, with bolts providing fastening, effectively improving the installation reliability of the air cylinder. The L-shaped structure of the suspended air cylinder crane allows the air cylinder to remain suspended even if bolts come loose, effectively controlling the risk of accidents caused by air cylinder detachment.

[0004] However, in actual use, the existing tank truck air cylinder cranes, although able to provide good support to increase lifting strength and prevent falling off during the lifting process as described in the aforementioned application, inevitably experience some swaying and swinging during the lifting process. This causes the air cylinder being supported to be affected by the swaying, and the lack of certain restrictions during the lifting process makes it still susceptible to slippage and even falling off. As a result, the stability is poor and there is still a certain risk. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hoist for air cylinders in high-speed rail tank cars. During hoisting, the air cylinder, supported by a support structure, utilizes its own weight to drive the limiting and auxiliary components to move synchronously. This allows the air cylinder to pull the connecting piece downwards, causing the connecting piece to pull the limiting pieces on both sides to rotate around the axis. This provides pressure and restraint to the inner side of the air cylinder, reducing its movement, improving stability, and preventing it from falling off.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-speed rail tank car air cylinder crane, comprising:

[0008] The support structure has an inner space for supporting the air cylinder;

[0009] The upper part of the support is equipped with a limiting component that moves around an axis. The limiting component includes: a slider, a pivot, a connector, and a limiting element.

[0010] The slider is connected to the inner side of the support body, the rotating shafts are all horizontally connected between the sliders, the limiting members are all installed on the surface of the rotating shafts, and the connecting members are connected between the limiting members;

[0011] The surface of the support is constructed with auxiliary components, and lifting components are installed on the surface of the support.

[0012] The present invention further provides that the auxiliary component includes: a movable groove and an elastic element;

[0013] The movable grooves are all opened at both ends of the upper part of the support body, and the elastic elements are all installed inside the lower part of the movable grooves. The movable ends of the elastic elements are all connected to the sliders.

[0014] The present invention is further configured such that the limiting member is located inside the movable groove, and the limiting member fits into the support body.

[0015] The present invention is further configured such that magnets are installed on both sides of the surface of the support, and the magnets are magnetically connected to the limiting member.

[0016] The present invention is further configured such that the connector is bent downward in the vertical direction.

[0017] The present invention further comprises the lifting assembly including: a fixing plate and a through hole;

[0018] The fixing plates are all installed on both sides of the surface of the support body, and the through holes are all opened through the surface of the fixing plates, and the fixing plates are connected to the hanging body.

[0019] The present invention is further configured such that the inner side of the support is arc-shaped, and the horizontal height of the limiting member is higher than the horizontal height of the support.

[0020] The beneficial effects of this utility model are as follows: When the air cylinder is hoisted, under the support of the support body, the air cylinder's own gravity can drive the limiting component and auxiliary component to move synchronously. At this time, the air cylinder can pull the connecting piece downward, so that the connecting piece can pull the limiting pieces on both sides to rotate around the pivot, thereby pressing and limiting the inner air cylinder to a certain extent, reducing the movement of the air cylinder, improving stability, and preventing it from falling off.

[0021] 1. The air cylinder crane for the high-speed rail tank car is equipped with limiting components, which allow the air cylinder to be supported and placed by the support body during hoisting. As the air cylinder is hoisted, the downward gravity generated by the air cylinder can pull the connecting parts downward. At this time, the limiting components connected to both ends of the connecting parts can be rotated under the action of the rotating shaft, so that the limiting components can press against the air cylinder after rotation. The air cylinder's own gravity is used to limit its movement, reduce the movement of the air cylinder, and improve stability.

[0022] 2. The air cylinder crane for the high-speed rail tank car is equipped with auxiliary components. Since the specifications of the air cylinders are different, their overall weight and volume are also different. At this time, the limiting component can also move downward in the vertical direction through the slider and elastic component, so that the limiting component can be adjusted in the vertical direction and can also be rotated to ensure the limiting effect on the air cylinder. This allows it to fit the air cylinder better to adapt to different specifications of air cylinders and improve flexibility. Attached Figure Description

[0027] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0028] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0029] In the description of this patent, it should be understood that the terms “center,” “upper,” “lower,” “front,” “back,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0030] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0031] Reference Figures 1 to 3 A high-speed rail tank car air cylinder hoist includes: a support body 1, the inner side of which has a space for supporting the air cylinder, ensuring that the air cylinder can be stably placed and hoisted; a limiting component that moves around an axis is installed on the upper part of the support body 1, so that the limiting component can clamp and limit the air cylinder to a certain extent, reducing the movement of the air cylinder; the limiting component includes: a slider 6, a rotating shaft 10, a connecting member 5, and a limiting member 4; the slider 6 is connected to the inner side of the support body 1, the rotating shaft 10 is horizontally connected between the sliders 6, the limiting member 4 is installed on the surface of the rotating shaft 10, and the connecting member 5 is connected between the limiting members 4, so that when the connecting member 5 is subjected to a downward traction force in the vertical direction, the connecting member 5 can pull the limiting member 4, at which time the limiting member 4 can be rotated and moved under the action of the rotating shaft 10; the surface of the support body 1 is constructed with an auxiliary component, which can provide a certain amount of movement space for the limiting member 4, improving the flexibility of the limiting member 4; the surface of the support body 1 is equipped with a lifting component, so that the lifting component can cooperate with the hoisting body to hoist the support body 1 and the air cylinder.

[0032] Specifically, refer to Figures 1 to 3 The auxiliary components include: movable grooves 8 and elastic elements 7; the movable grooves 8 are all opened at the upper two ends of the support body 1, and the elastic elements 7 are all installed inside the lower part of the movable grooves 8. The movable ends of the elastic elements 7 are all connected to the sliders 6. Through this implementation, the limiting member 4 can also move downward in the vertical direction through the sliders 6 and the elastic elements 7, so that the limiting member 4 can be adjusted in the vertical direction and can also be rotated to ensure the limiting effect on the air cylinder, thereby better fitting with the air cylinder to adapt to air cylinders of different specifications and improving flexibility.

[0033] Furthermore, the limiting member 4 is located inside the movable groove 8, and the limiting member 4 fits against the support body 1. This design improves the stability of the limiting member 4 during the flipping movement and prevents the limiting member 4 from shifting, so that the limiting member 4 can be better fixed in conjunction with the air cylinder.

[0034] Furthermore, magnets 9 are installed on both sides of the surface of the support body 1. The magnets 9 are magnetically connected to the limiting member 4. With this design, when the hoisted air cylinder is lowered, as the support body 1 moves downward, the air cylinder can push the limiting member 4 to flip upward. Then the magnets 9 can also attract the limiting member 4 to drive the limiting member 4 back to its initial position, which facilitates subsequent hoisting operations.

[0035] Furthermore, the connector 5 is constructed to be bent downwards in the vertical direction. This design allows the connector 5 to have a certain amount of room to move, so that the connector 5 can move together with the pressure of the air cylinder, and also provides a certain amount of room to move for the limiting member 4 and the air cylinder.

[0036] Specifically, refer to Figures 1 to 2 The lifting assembly includes: a fixed plate 2 and a through hole 3; the fixed plate 2 is installed on both sides of the surface of the support body 1, and the through hole 3 is opened through the surface of the fixed plate 2. The fixed plate 2 is connected to the lifting body. In this embodiment, the lifting body can be connected to the fixed plate 2 through the through hole 3, so that the lifting body can drive the support body 1 to move when it moves. The lifting assembly can provide connection support for the support body 1.

[0037] Furthermore, the inner side of the support body 1 is arc-shaped, and the horizontal height of the limiting member 4 is higher than that of the support body 1. This design can better fit the outer contour of the air cylinder, which helps to reduce the shaking of the air cylinder during hoisting and improve hoisting stability. At the same time, the limiting member 4 can provide a greater range of limitation for the air cylinder.

[0038] Working principle: When using this utility model, first connect the lifting body to the fixed plate 2 so that the support body 1 can support the air cylinder. Then, when it is lifted upwards by hoisting, the downward gravity generated by the air cylinder can pull the connecting piece 5 downwards. At this time, the limiting piece 4 connected to both ends of the connecting piece 5 can be flipped under the action of the rotating shaft 10 so that the limiting piece 4 can press and clamp the air cylinder after flipping. The air cylinder's own gravity is used to limit it to a certain extent, reducing the movement of the air cylinder and improving stability. Since the specifications of the air cylinders are different, their overall weight and volume are also different. At this time, the limiting piece 4 can also move downwards in the vertical direction through the slider 6 and the elastic piece 7, so that the limiting piece 4 can be adjusted in the vertical direction and can also be flipped to ensure the limiting effect on the air cylinder, thereby fitting well with the air cylinder to adapt to different specifications of air cylinders and improve flexibility.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
