Description

Technical Field

[0001] This invention relates to the field of machine tools, and in particular to an installation device, application, and method for a cap-shaped beam hanging bolt. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] The cap beam is a common beam used in rail vehicles, such as power vehicles. Large, critical equipment under the vehicle is typically fixed to the cap beam guide rails using hanging bolts. Because the cap beam is made of a different material than the hanging bolts, a special zinc chromate resin primer is generally required to prevent the formation of galvanic cells when dissimilar metals are in contact. Therefore, the inside of the cap beam is coated with a special zinc chromate resin primer. (Reference) Figure 1 As shown, a portal-shaped section is provided at the bottom of the cap-shaped beam 2, and a cap-shaped beam guide rail 14 is provided inside the portal-shaped section. When installing the hanging bolt 1, it is necessary to first enter through the end of the cap-shaped beam guide rail 14, and then manually move it to the corresponding installation position. The inventor found that there are several problems in the installation process of the hanging bolt:

[0004] Manually moving the hanging bolts results in a slow movement speed.

[0005] During the movement of the hanging bolts, the zinc chromate special resin primer on the inner surface of the hat-shaped beam guide rail is easily damaged. Moreover, since the zinc chromate special resin primer is inside the hat-shaped beam, it is relatively difficult and complex to observe, and it is difficult to find the damaged area. If damage occurs, it is also difficult to repair due to the narrow working space.

[0006] Definition: Electrochemical corrosion caused by two or more metals with different electrode potentials coming into contact with each other in a corrosive medium, also known as contact corrosion or bimetallic corrosion, requires the application of a special zinc chromate resin primer. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the primary objective of this invention is to provide an installation device for hanging bolts on cap-shaped beams, which solves the problem that hanging bolts on cap-shaped beams are prone to damaging the zinc chromate special resin primer, thereby improving the installation efficiency of hanging bolts.

[0008] The second objective of this invention is to provide an application of a mounting device for a cap-shaped beam suspension bolt, which can be used for the installation of equipment under rail vehicles.

[0009] The third objective of this invention is to provide a method for installing equipment under a rail vehicle, which facilitates the movement of hanging bolts and improves the installation efficiency of the equipment under the vehicle.

[0010] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0011] An installation device for a cap-shaped beam hanging bolt includes a first support and a second support. The first support and the second support are arranged opposite to each other and are movably connected on one side, so that at least one of them can rotate relative to the other. The first support and the second support are respectively provided with moving parts, which can contact the outer surface of the cap-shaped beam. An external force pushes the first support and the second support to move along the length of the section where the cap-shaped beam guide rail is located. Clamping parts are respectively provided on the opposite sides of the first support and the second support. The two clamping parts clamp the bolt of the hanging bolt and keep the hanging bolt suspended relative to the cap-shaped beam.

[0012] As described above, the first support member and the second support member are movably connected. After rotating relative to the other, one of them can be hooked onto the cap-shaped beam. The clamping component clamps the cap-shaped beam and prevents the hanging bolt from contacting the cap-shaped beam. When an external force pushes the first support member and the second support member, the hanging bolt can be moved quickly along the section of the cap-shaped beam guide rail under the action of the moving component, effectively preventing the hanging bolt from damaging the zinc chromate special resin primer during the movement.

[0013] As described above, in a mounting device for a cap-shaped beam hanging bolt, the bottom sides of the first support member and the second support member are hinged, such that at least one of the first support member or the second support member is rotatable relative to the other, which facilitates placing the mounting device on the cap-shaped beam.

[0014] As described above, in a type of installation device for hanging bolts of a hat-shaped beam, the bottom sides of the first support member and the second support member are connected by a hinge ring. The inner diameter of the hinge ring is larger than the diameter of the bolt thread, so that the bolt thread of some hanging bolts can pass through the hinge ring. In this way, the bolt thread of longer hanging bolts can pass through the hinge ring without making the entire installation device too large, thus avoiding interference during movement.

[0015] As described above, in the installation device for the hanging bolt of the hat-shaped beam, considering that the clamping component needs to clamp the thread of the hanging bolt, the clamping component is connected to the first support and the second support respectively through the connector;

[0016] The clamping component includes a semi-ring structure with a set height. The shape of the inner side of the two semi-ring structures is adapted to the shape of the screw part. The clamping components on both sides clamp the screw of the hanging bolt from both sides.

[0017] As described above, in a mounting device for a cap-shaped beam hanging bolt, the moving part is located above the clamping part, taking into account the structural arrangement.

[0018] The clamping component is located between the connection between the first support member and the second support member and the moving component, thus making the structure of the installation device reasonable.

[0019] As described above, the mounting device for hanging bolts of a hat-shaped beam includes a moving component comprising a first moving wheel mounted on the top side of the first support member and the second support member. Under the action of external force, the first moving wheel can move along the upper plane of the section where the hat-shaped beam guide rail is located.

[0020] The first moving wheel is connected to the first support member and the second support member respectively through the first connecting shaft. The first connecting shaft is set parallel to the upper surface of the hat-shaped beam guide rail, so that the first moving wheel can rotate relative to the first connecting shaft, thereby facilitating the movement of the entire device.

[0021] As described above, the mounting device for the hanging bolts of the hat-shaped beam further ensures smooth movement of the mounting device along the section where the hat-shaped beam guide rail is located. The moving component also includes a second moving wheel installed in the middle section of the first support member and the second support member. Under the action of external force, the second moving wheel can move along the lower surface of the section where the hat-shaped beam guide rail is located. The second moving wheel is located below the first moving wheel. This arrangement of multiple moving wheels helps to ensure the stability of the device during movement.

[0022] The second movable wheel is connected to the first support and the second support respectively via the second connecting shaft, and the first connecting shaft and the second connecting shaft are arranged parallel to each other.

[0023] As described above, the mounting device for the hanging bolts of the hat-shaped beam includes a third moving wheel that can roll along the side of the section where the hat-shaped beam guide rail is located. The central axis of the third moving wheel is perpendicular to the central axis of the first moving wheel. The third moving wheel is fixed to the inner side of the first support member and the second support member. The third moving wheel is located between the first moving wheel and the second moving wheel. The first moving wheel and the second moving wheel are arranged vertically opposite each other. The third moving wheel is provided with lateral constraints on both sides of the section where the hat-shaped beam guide rail is located, which can further ensure the stability of the movement of the moving component.

[0024] As described above, in a mounting device for hanging bolts of a hat-shaped beam, the first support member and the second support member have the same structure;

[0025] The length and width of the first support member are adjustable, which can effectively ensure reliable contact between the moving part and the surface of the cap beam. Moreover, the first and second support members can be adjusted according to cap beams of different widths and heights to suit cap beams of different sizes.

[0026] As described above, in the installation device for hanging bolts of a hat-shaped beam, the first support member and the second support member are respectively a first support rod and a second support rod;

[0027] The first support rod and the second support rod are both L-shaped. One side of the first support rod can be placed on one side of the width direction of the cap beam, and the other side of the first support rod can be placed on the bottom side of the cap beam. One side of the second support rod can be placed on the other side of the width direction of the cap beam, and the other side of the second support rod can be placed on the bottom side of the cap beam. The L-shaped structure of the first and second support rods is reasonably designed.

[0028] Secondly, the present invention also provides an application of an installation device for a cap-shaped beam hanging bolt, which is used in rail vehicles.

[0029] Thirdly, the present invention also provides a method for installing equipment under a rail vehicle, using the aforementioned mounting device for cap-shaped beam hanging bolts, comprising the following:

[0030] Place the hanging bolts for the undercarriage equipment to be installed at the end of the hat-shaped beam guide rail;

[0031] The first support member and the second support member are respectively equipped with the clamping component and the moving component;

[0032] The first support and the second support are respectively placed on both sides of the cap-shaped beam. The first support and the second support are arranged opposite to each other. The bottom sides of the first support and the second support are movably connected, and the moving part contacts the cap-shaped beam.

[0033] The clamping component clamps the threaded rod of the hanging bolt, keeping the hanging bolt suspended relative to the cap beam;

[0034] Push the first support member and / or the second support member so that the moving part moves along the length of the section where the hat-shaped beam guide rail is located, and stops after moving to the installation position of the undercarriage equipment. The hanging bolt passes through the undercarriage equipment to be installed and is locked by fasteners.

[0035] The beneficial effects of the present invention are as follows:

[0036] 1) The installation device of the present invention is configured such that the first support member and the second support member are movably connected, and one of them can be hung on the cap beam after rotating relative to the other. The clamping member clamps the cap beam and can prevent the hanging bolt from contacting the cap beam. When the external force pushes the first support member and the second support member, the hanging bolt can be moved quickly along the section of the cap beam guide rail under the action of the moving member, so that the hanging bolt can be quickly moved to the position to be installed, which greatly improves the work efficiency. Moreover, because the clamping member is set, it can effectively ensure that the hanging bolt is kept in a suspended state, effectively avoiding damage to the zinc chromate special resin primer during the movement of the hanging bolt, thereby avoiding the problems caused by damage to the primer.

[0037] 2) In this invention, the first support member and the second support member are hinged together, and their bottom sides can be connected by a hinge ring. In this way, the screw of the longer hanging bolt can pass through the hinge ring without interfering with the installation device.

[0038] 3) The moving component in this invention includes a first moving wheel that can move along the upper surface of the section where the hat-shaped beam guide rail is located, and a second moving wheel that can move along the lower surface of the section where the hat-shaped beam guide rail is located. The first and second moving wheels are arranged vertically, which helps to ensure the stability of the installation device during movement. Furthermore, the setting of the third moving wheel can increase lateral constraints and further ensure the stability of movement.

[0039] 4) The overall structure of the device of the present invention is reasonable, flexible and practical. The length and width of the first support and the second support are adjustable, which is not only suitable for hanging bolts of different lengths, but also for cap beams of different widths and heights, thus broadening the application range of the installation device.

[0040] 5) The installation method for the undercarriage equipment provided by the present invention has a moving part of the installation device that contacts the cap beam and is movable relative to the cap beam. The clamping part can clamp the screw of the hanging bolt and make the hanging bolt suspended in the air without contacting the cap beam, thereby avoiding damage to the primer on the inner guide rail surface of the cap beam. The installation device drives the hanging bolt to move quickly, effectively improving the installation efficiency of the undercarriage equipment. Attached Figure Description

[0053] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0054] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0055] As described in the background section, existing technologies suffer from slow movement speed of hanging bolts and easy damage to the primer. To address these technical issues, this invention proposes an installation device for hanging bolts on a cap-shaped beam.

[0056] Example 1

[0057] In a typical embodiment of the present invention, reference is made to Figure 2As shown, an installation device for a cap-shaped beam hanging bolt includes a first support member 9 and a second support member 10. The first support member 9 and the second support member 10 are arranged opposite to each other and are movably connected on one side, so that at least one of them can rotate relative to the other. The first support member 9 and the second support member 10 are respectively provided with moving parts, which can contact the outer surface of the cap-shaped beam 2. An external force pushes the first support member 9 and the second support member 10 to move along the length of the section where the cap-shaped beam guide rail is located. The opposite sides of the first support member 9 and the second support member 10 are respectively provided with clamping parts 6. The two clamping parts 6 clamp the screw of the hanging bolt 1 and keep the hanging bolt 1 suspended relative to the cap-shaped beam 2, that is, after the clamping parts clamp the hanging bolt, the hanging bolt does not contact the inner surface of the cap-shaped beam guide rail.

[0058] In some examples, the bottom sides of the first support member 9 and the second support member 10 are hinged together. Specifically, the bottom side of the first support member 9 is provided with a retaining ring, and the bottom side of the second support member 10 is provided with a rotating shaft. The rotating shaft is inserted into the retaining ring and can rotate relative to the retaining ring. This allows the second support member to rotate relative to the first support member, and the first support member to rotate relative to the second support member. After rotation, it is convenient to place the mounting device on the cap beam.

[0059] In this embodiment, the bottom sides of the first support member 9 and the second support member 10 are connected by a hinge ring 5. The plane of the hinge ring 5 is parallel to the plane of the diameter of the hanging bolt thread. Specifically, the hinge ring 5 is an existing hinge ring. The hinge ring 5 includes a body, which is an arc-shaped structural member. Rotatable members are movably connected to both sides of the body. The bottom side of the first support member 9 is connected to the rotatable member on one side, and the bottom side of the second support member 10 is connected to the rotatable member on the other side. A locking mechanism is provided between the rotatable members on both sides, preferably a locking buckle. The locking buckle can be opened and closed. The locking buckle is an existing locking buckle. After the thread of the hanging bolt passes through the hinge ring, the clamping component clamps the thread of the hanging bolt, and the locking buckle locks the rotatable members on both sides. The inner diameter of the hinge ring is larger than the diameter of the hanging bolt thread, so that part of the hanging bolt thread can pass through the hinge ring. In this way, the thread of the longer hanging bolt can pass through the hinge ring without making the entire installation device too large, thus avoiding interference during movement.

[0060] Considering that the clamping component needs to clamp the screw of the hanging bolt, the clamping component 6 is connected to the first support 9 and the second support 10 respectively through a connector. In this embodiment, the connector is specifically a connecting rod.

[0061] It should be explained that the clamping component 6 includes a semi-ring structure with a set height. The shape of the inner side of the two semi-ring structures is adapted to the shape of the screw. After the two semi-ring structures hold the hanging bolt, they are closed into a cylindrical shape. A rubber pad is fixed on the inner side of the semi-ring structure to avoid damage to the screw. The clamping components on both sides of the hanging bolt screw clamp the screw from both sides.

[0062] Considering the structural design, the moving part is located above the clamping part 6; the clamping part 6 is located between the connection between the first support 9 and the second support 10 and the moving part, thus making the structural design of the installation device reasonable.

[0063] It should be explained that the moving part includes a first moving wheel 3 installed on the top side of the first support member 9 and the second support member 10. The two first moving wheels 3 are spaced apart. Under the action of external force, the first moving wheel 3 can move along the upper surface of the section where the hat-shaped beam guide rail is located.

[0064] The first moving wheel 3 is connected to the first support member 9 and the second support member 10 respectively through the first connecting shaft 7. The first connecting shaft 7 is perpendicularly connected to the vertical section of the first support member 9. The first connecting shaft 7 is set parallel to the upper surface of the hat-shaped beam guide rail, so that the first moving wheel 3 can rotate relative to the first connecting shaft, thereby facilitating the movement of the entire installation device.

[0065] To further ensure the smooth movement of the installation device along the section of the hat-shaped beam guide rail, the moving component also includes a second moving wheel 4 installed in the middle section of the first support member 9 and the second support member 10. Under the action of external force, the second moving wheel 4 can move along the lower surface of the section of the hat-shaped beam guide rail. The second moving wheel 4 is located below the first moving wheel 3. This arrangement of multiple moving wheels helps to ensure the stability of the device during movement.

[0066] The second movable wheel 4 is connected to the first support member 9 and the second support member 10 respectively through the second connecting shaft 8. The second movable wheel 4 is rotatable relative to the second connecting shaft 8. The first connecting shaft 7 and the second connecting shaft 8 are arranged parallel to each other. The first connecting shaft 7 and the second connecting shaft 8 can have a set length, and the two lengths can be the same.

[0067] To avoid scratching the outer surface of the cap-shaped beam, the first moving wheel 7 and the second moving wheel 8 are both made of soft material, preferably rubber wheels.

[0068] It should be explained that the first support member 9 and the second support member 10 have the same structure, and the entire installation device is symmetrically arranged with the central axis of the screw of the hanging rod bolt held by the clamping component as the center line;

[0069] In this embodiment, the first support member 9 and the second support member 10 are respectively the first support rod and the second support rod; the first support rod and the second support rod are both L-shaped, each including a vertical section and a horizontal section connected to the vertical section. The vertical section of the first support rod can be placed on one side of the width direction of the cap beam, and the horizontal section of the first support rod can be placed on the bottom side of the cap beam; the vertical section of the second support rod can be placed on the other side of the width direction of the cap beam, and the horizontal section of the second support rod can be placed on the bottom side of the cap beam. The L-shaped structure of the first support rod and the second support rod is reasonably designed, which not only facilitates the hinged connection between the first support rod and the bottom side of the first support rod, but also makes it convenient for moving parts to be installed on the first support rod and the second support rod.

[0070] In addition, the length and width of the first support member 9 are adjustable. Correspondingly, the length and width of the second support member 10 are also adjustable, which can effectively ensure reliable contact between the moving parts and the surface of the cap beam. When the clamping parts clamp the screw of the hanging bolt so that the hanging bolt does not contact the inner surface of the guide rail of the cap beam, the lengths of the first support member 9 and the second support member 10 are adjusted so that the first moving wheel 3 and the second moving wheel 4 are in reliable contact with the cap beam 2. Moreover, the first support member and the second support member can be adjusted according to cap beams of different widths and heights to be suitable for cap beams of different sizes.

[0071] In some examples, the horizontal and vertical sections of the first support member 9 and the second support member 10 respectively include telescopic structural members. The telescopic structural members include a fixed rod and a movable rod. The fixed rod and the movable rod are connected by an axial moving member to achieve length adjustment. The axial moving member can be an existing spline structural member with a locking function. Of course, the first support member 9 and the second support member 10 can also be other telescopic structural members, such as the vertical section including multiple sleeves. Adjacent sleeves can be locked together. The length or width of the first support member 9 and the second support member 10 can be adjusted by adjusting the extension length of one sleeve relative to another sleeve.

[0072] refer to Figure 5 As shown, considering that the first moving wheel 3 and the second moving wheel 4, which are set up vertically, both need to contact the hat-shaped beam 2, the vertical sections of the first support member 9 and the second support member 10 each include two telescopic structural members 11, one of which is located between the second connecting shaft and the clamping component, and the other of which is located between the first connecting shaft and the second connecting shaft; in addition, telescopic structural members 11 are provided at the horizontal sections of the first connecting shaft 7, the second connecting shaft 8, the first support member and the second support member.

[0073] The installation device provided in this embodiment has a simple structure. The first support member and the second support member are movably connected. After one of them rotates relative to the other, it can be hung on the cap beam. The clamping component clamps the cap beam and prevents the hanging bolt from contacting the cap beam. When an external force pushes the first support member and the second support member, the hanging bolt can be moved quickly along the section of the cap beam guide rail under the action of the moving component. This effectively avoids the hanging bolt from damaging the zinc chromate special resin primer during the movement. Moreover, the length and width of the first support member and the second support member are adjustable, making it suitable not only for hanging bolts of different lengths but also for cap beams of different widths and heights, thus broadening the application range of the installation device.

[0074] Example 2

[0075] The difference between this embodiment and Embodiment 1 is that:

[0076] refer to Figure 6 , Figure 7 and Figure 8 As shown, the moving component also includes a third moving wheel 12 that can roll along the side of the section where the hat-shaped beam is located. The central axis of the third moving wheel 12 is perpendicular to the central axis of the first moving wheel 3. The third moving wheel 12 is fixed to the inner side of the first support member 9 and the second support member 10. The third moving wheel 12 is located between the first moving wheel 3 and the second moving wheel 4. The first moving wheel 3 and the second moving wheel 4 are arranged vertically opposite each other. The arrangement of the third moving wheel 12 is equivalent to adding lateral constraints on both sides of the section where the hat-shaped beam guide rail 14 is located, which can further ensure the stability of the moving component moving along the section where the hat-shaped beam guide rail is located.

[0077] Specifically, the third moving wheel 12 is fixed to the first support member and the second support member through the L-shaped connecting shaft 13, so that the central axis of the third moving wheel 12 is perpendicular to the central axis of the first moving wheel and the second moving wheel.

[0078] Moreover, in some examples, the vertical sections of the first support member 9 and the second support member 10 each include two vertical rods 15, which are parallel to each other and spaced apart. The two vertical rods 15 are connected by a horizontal rod 16, and the bottom ends of the two vertical rods 15 are connected to the hinge ring 5 by a Y-shaped connector 17.

[0079] refer to Figure 9 As shown in this embodiment, the L-shaped connecting shaft 13 can also be provided with a telescopic structure, and the first support and the second support are respectively provided with telescopic structures between the L-shaped connecting shaft and the second connecting shaft.

[0080] It is understandable that in other examples, the moving parts only include the first moving wheel 3 and the third moving wheel 12, which can also ensure the reliable movement of the moving parts along the section of the hat-shaped beam guide rail.

[0081] Example 3

[0082] This embodiment provides an application of the installation device for the cap-shaped beam hanging bolts described in Embodiment 1 or Embodiment 2, which is applied to rail vehicles and can be used for the installation of equipment under the rail vehicle.

[0083] Example 4

[0084] This embodiment provides a method for installing equipment under a rail vehicle, using a mounting device for cap-shaped beam hanging bolts as described in Embodiment 1 or Embodiment 2, including the following:

[0085] Place the hanging bolt 1 of the undercarriage equipment to be installed at the end of the guide rail of the hat-shaped beam 2;

[0086] The first support member 9 and the second support member 10 are respectively equipped with the clamping component 6 and the moving component;

[0087] Adjust the length of the horizontal section of the first support member 9 and the second support member 10 according to the width of the hat-shaped beam 2, that is, adjust the width of the first support member and the second support member;

[0088] The first support member 9 and the second support member 10 are respectively placed on both sides of the cap-shaped beam 2. The first support member 9 and the second support member 10 are arranged opposite to each other, and the bottom sides of the first support member and the second support member are hinged together.

[0089] Clamping component 6 clamps the thread of hanging bolt 1, keeping hanging bolt 1 suspended relative to the cap beam. (Refer to...) Figure 3 As shown, the threaded rod of the longer hanging bolt passes through the hinge ring 5, as referenced. Figure 4 As shown, the screw of the shorter hanging bolt did not reach the position of the hinge ring 5. The length of the vertical section of the first support member 9 and the second support member 10 was adjusted so that the two first moving wheels 3 contacted the upper surface of the hat-shaped beam 2 respectively, and the two second moving wheels 4 contacted the lower surface of the hat-shaped beam respectively.

[0090] Push the first support member and / or the second support member so that the first and second moving wheels move along the length of the section where the hat-shaped beam guide rail is located, and stop after moving to the installation position of the undercarriage equipment. The hanging bolts pass through the undercarriage equipment to be installed and are locked by fasteners.

[0091] In this embodiment, an installation device is used to install the undercarriage equipment, which effectively avoids damaging the primer on the inner guide rail surface of the hat-shaped beam. The installation device drives the hanging bolts to move quickly, which effectively improves the installation efficiency of the undercarriage equipment.

[0092] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
