Description

Technical Field

[0001] This application relates to the field of railway tool technology, and in particular to an installation auxiliary tool. Background Technology

[0002] Currently, China's railway industry is developing rapidly, and the amount of track construction is gradually increasing. During the track laying process, the ends of adjacent connecting rails are connected and tightened together through rail joints. Freezing clamps, as the most commonly used clamps for heavy-haul railway joints, are used frequently and provide excellent reinforcement for heavy-haul railway joints.

[0003] Because the frozen clamp itself is heavy, the rail head-rail waist arc and the rail waist-rail bottom arc need to be installed tightly during rail web installation. This makes it difficult and cumbersome for inexperienced workers to operate the clamp.

[0004] However, there are currently no special installation tools for frozen rail clamps on the market. Frozen rail clamps can only be installed manually. When installing frozen rail clamps for 75kg / m rail joints, only strong and experienced people can carry out the installation work. Other people cannot lift them and are very likely to squeeze and bump their hands and feet, causing personal injury. Utility Model Content

[0005] Based on this, this application provides an installation assistance tool to solve the problem of inconvenient installation of freezing clamps in related technologies.

[0006] This application provides an installation auxiliary tool, which includes: a clamping member with an operating part protruding from the surface of the clamping member; and a limiting structure including a connecting part for detachable connection with a freezing clamp and a limiting part for limiting cooperation with the freezing clamp, wherein the connecting part and the limiting part are respectively disposed on the clamping member and extend to the same side of the clamping member, and the limiting structure enables the clamping member to remain stationary relative to the freezing clamp.

[0007] In one embodiment, the clamping member includes a clamping plate and a connecting plate connected to each other, the clamping plate and the connecting plate being arranged at an angle, the operating part and the limiting part being disposed on the clamping plate, and the connecting part being disposed on the connecting plate.

[0008] In one embodiment, the operating part, the connecting part, and the limiting part are not collinear.

[0009] In one embodiment, the connecting part includes a connecting post connected to the side of the connecting plate, and the connecting post is used to engage with the hole segment of the freezing clamp.

[0010] In one embodiment, the limiting part includes a limiting post, which is connected to the side of the clamping plate and is disposed on the same side of the clamping plate as the connecting post. The limiting post is used to fit against the outer wall of the freezing clamping plate.

[0011] In one embodiment, the outer diameter of the limiting post is less than or equal to the outer diameter of the connecting post.

[0012] In one embodiment, the operating part includes a grip lever connected to the side of the clamping plate.

[0013] In one embodiment, the operating unit includes two gripping rods located on opposite sides of the clamping plate.

[0014] In one embodiment, the installation aid includes two clamping members, which are respectively disposed at both ends of the freezing clamp, with the connecting portions of the two clamping members disposed opposite to each other, and the limiting portions of the two clamping members disposed opposite to each other.

[0015] In one embodiment, the operating part, the connecting part, and the limiting part are all integrally formed with the clamping member.

[0016] By applying the technical solution of this application, the connecting part of the limiting structure is detachably connected to the freezing clamp. The limiting part of the limiting structure engages with the freezing clamp, allowing the clamp to remain stationary relative to the freezing clamp through the interaction between the connecting part and the limiting part when the operator manipulates the clamping component via the operating part. This allows the operator to move the freezing clamp to the joint position using an installation auxiliary tool. When installing the clamp at the rail web position, this avoids manual contact between the clamp and the gap in the rail web, eliminating the possibility of personal injury during operation. Compared to manual handling, the installation auxiliary tool of this application improves operational efficiency and enhances safety. Attached Figure Description

[0022] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0023] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0024] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0025] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0026] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0027] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0028] See Figures 1 to 3 , Figure 1 A schematic diagram of the installation assistance tool provided in an embodiment of this application is shown. Figure 2 An assembly diagram of the installation aids and freezing clamps provided in the application embodiment is shown. Figure 3 This illustration shows another assembly diagram of the installation aid and freezing clamp provided in an embodiment of the application. One embodiment of this application provides an installation aid including a clamping member 10 and a limiting structure 20. The clamping member 10 is provided with an operating part 11, which protrudes from the surface of the clamping member 10. The limiting structure 20 includes a connecting part 21 for detachable connection with the freezing clamp 30 and a limiting part 22 for limiting engagement with the freezing clamp 30. The connecting part 21 and the limiting part 22 are respectively disposed on the clamping member 10, extending to the same side of the clamping member 10. The limiting structure 20 enables the clamping member 10 to remain stationary relative to the freezing clamp 30.

[0029] By applying the technical solution of this application, the connecting part 21 of the limiting structure 20 is detachably connected to the freezing clamp 30, and the limiting part 22 of the limiting structure 20 is used to limit the freezing clamp 30. When the operator operates the clamping part 10 through the operating part 11, the interaction between the connecting part 21 and the limiting part 22 keeps the clamping part 10 stationary relative to the freezing clamp 30. The operator can then use the installation auxiliary tool to move the freezing clamp 30 to the joint position. This avoids human contact with the gap between the clamp and the rail web when installing the clamp on the rail web, eliminating the possibility of personal injury during operation. Compared to manual handling, the installation auxiliary tool of this application improves operational efficiency and enhances safety.

[0030] Specifically, when the auxiliary tool is installed to move the freezing clamp 30, since both the connecting part 21 and the limiting part 22 cooperate with the freezing clamp 30, the contact points between the connecting part 21 and the freezing clamp 30 and the contact points between the limiting part 22 and the freezing clamp 30 can generate torques in opposite directions, thereby keeping the clamping member 10 and the freezing clamp 30 relatively stationary, so that the operator can apply force to move the freezing clamp 30.

[0031] In this embodiment, the operation unit 11 is operated manually by the operator. In other embodiments, the operator can use tools in conjunction with the operation unit 11, thereby enabling the operator to operate with additional tools to further reduce effort.

[0032] The operating part 11, the connecting part 21, and the limiting part 22 can be integrally formed with the clamping member 10, including by welding. Alternatively, one, two, or more of the operating part 11, the connecting part 21, and the limiting part 22 can be detachably connected to the clamping member 10.

[0033] It should be noted that the clamping member 10 of this application is only used on one end of the freezing clamp 30. That is, when using it, the operator can only install the clamping member 10 on one end of the freezing clamp 30 to lift that one end of the freezing clamp 30. At the other end of the freezing clamp 30, the operator can lift the freezing clamp 30 in other ways. Of course, the clamping member 10 can also be used on the other end to lift both ends of the freezing clamp 30 at the same time.

[0034] Combination Figure 1As shown, the clamping member 10 includes a clamping plate 12 and a connecting plate 13 connected to each other. The clamping plate 12 and the connecting plate 13 are arranged at an angle. The operating part 11 and the connecting part 21 are disposed on the clamping plate 12, and the limiting part 22 is disposed on the connecting plate 13. With the clamping member 10 designed as described above, the connecting part 21 and the limiting part 22 are respectively provided on the clamping plate 12 and the connecting plate 13 arranged at an angle, so that the connecting part 21 and the limiting part 22 respectively cooperate with different positions of the freezing clamp 30, and can generate torques in different directions when the operator applies force.

[0035] Combination Figure 1 As shown, the operating part 11, the connecting part 21, and the limiting part 22 are not collinear. This design is ergonomic and allows operators to perform tasks more efficiently.

[0036] In some embodiments, the connecting part 21 includes a connecting post connected to the side of the clamping plate 12. The connecting post is used to insert into a hole in the freezing clamping plate 30. By providing the connecting post, the insertion and engagement of the connecting post with the hole facilitates the assembly and disassembly of the clamping member 10 and the freezing clamping plate 30, thereby saving operation time.

[0037] Combination Figure 1 As shown, the limiting part 22 includes a limiting post, which is connected to the side of the clamping plate 12 and is located on the same side of the clamping plate 12 as the connecting post. The limiting post is used to fit against the outer wall of the freezing clamping plate 30. With the above design, by utilizing the fit between the outer wall of the freezing clamping plate 30 and the limiting post, the position of the limiting post has a large adjustment margin, allowing reasonable adjustment space for the connecting post and the hole section of the freezing clamping plate 30, thereby enabling the clamping member 10 to have a suitable clamping position.

[0038] The operating part 11 and the connecting part 21 are spaced apart along the length of the clamping plate 12.

[0039] In some embodiments, the connecting portion 21 is located between the operating portion 11 and the limiting portion 22, as projected along the axial direction of the clamping member 10. During use, the connecting portion 21 is inserted into the hole of the freezing clamp 30, and the limiting portion 22 contacts the side wall of the freezing clamp 30. When the operator moves the freezing clamp 30, the clamping member 10 will not rotate relative to the freezing clamp 30 about the connecting post due to the limiting effect of the limiting portion 22 and the freezing clamp 30.

[0040] In some embodiments, the limiting portion 22 is located between the connecting portion 21 and the operating portion 11, as projected along the axial direction of the clamping member 10. During use, the connecting portion 21 engages with the hole in the freezing clamp 30, and the limiting portion 22 contacts the bottom wall of the freezing clamp 30. This also prevents the clamping member 10 from rotating relative to the freezing clamp 30.

[0041] Specifically, the outer diameter of the limiting post is less than or equal to the outer diameter of the connecting post. When the operator moves the freezing clamp 30, the connecting post applies an upward lifting force to the freezing clamp, causing the shear stress on the connecting post to be greater than the shear stress on the limiting post. With the above design, the structural strength of the connecting post can meet the requirements.

[0042] Combination Figure 1 As shown, the operating part 11 includes a gripping rod connected to the side of the clamping plate 12. With this design, the operator can lift the clamping member 10 by gripping the gripping rod. The structure is simple and easy to operate.

[0043] Combination Figure 1 As shown, the operating unit 11 includes two grip levers, which are located on both sides of the clamping plate 12. By providing grip levers on both sides of the clamping plate 12, the operator can operate by gripping either one of the grip levers or by gripping both grip levers simultaneously, which allows the operator to choose the grip lever according to their own habits and improves flexibility.

[0044] In some embodiments, the two grip levers are coaxially arranged to facilitate operation by the operator.

[0045] Combination Figure 1 As shown, the installation auxiliary tool includes two clamping parts 10, which are respectively positioned at both ends of the freezing clamp 30. The connecting portions 21 of the two clamping parts 10 are positioned opposite each other, and the limiting portions 22 of the two clamping parts 10 are positioned opposite each other. With the above design, by setting two clamping parts 10, it is convenient for two operators to operate the freezing clamp 30 simultaneously using the two clamping parts 10 respectively.

[0046] Specifically, two operators stand at opposite ends of the freezing clamp 30, each holding a clamp 10. The connecting posts are inserted into the holes at opposite ends of the freezing clamp 30, and the limiting posts are aligned with the side walls at opposite ends of the freezing clamp 30. When the two operators pull the two clamps 10 upwards together, a lifting force is simultaneously applied to both ends of the freezing clamp 30, thereby moving the freezing clamp 30.

[0047] Two operators each hold two clamps 10 to facilitate the handling and installation of the freezing clamp 30. When installing the clamp on the rail web, the operator avoids contact between the clamp and the gap between the rail web and the operator's hands, thus eliminating the possibility of personal injury during the operation.

[0048] In some embodiments, the operating part 11, the connecting part 21, and the limiting part 22 are all integrally formed with the clamping member 10. This design offers advantages such as simple structure, high strength, and ease of processing.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
