Description

Technical Field

[0001] This invention relates to the field of aluminum cantilever arms for overhead contact lines, and more specifically to a pre-assembly device for a single lug of an aluminum cantilever arm. Background Technology

[0002] With the rapid development of railway construction in my country, new requirements have been placed on the process quality standards of related components in the railway industry, and the requirements for the precision of the construction and maintenance of railway lines are becoming increasingly stringent. In railway lines, the overhead contact system is a crucial component ensuring normal railway operation. Connected to the electrified railway power supply lines, it directly undertakes the primary task of supplying energy to electric trains. The cantilever arm is the support device for the overhead contact system, and its pre-assembly is an important aspect of electrified railway construction. High-speed railways have extremely high precision requirements for overhead contact system installation. Since most components of high-speed railway overhead contact system projects cannot be repeatedly disassembled and reassembled, the cantilever arm support device must be precisely assembled in one go after accurate calculations. Due to constraints such as high altitude conditions on site, a pre-fabrication method based on ground batches is necessary. The quality of the first-time installation of the entire contact suspension directly affects the quality, progress, and efficiency of subsequent construction. Aluminum cantilever arms include flat cantilever arms and angled cantilever arms. Flat cantilever arms include a cantilever tube and a combined load-bearing cable seat, sleeve seat, and single lug fixed to the cantilever tube. An angled cantilever arm includes a cantilever tube and a sleeve seat and single lug fixed to the cantilever tube. In the assembly process of aluminum cantilever arms, it is necessary to pre-assemble the single ear first, and then assemble the sleeve seat and combined load-bearing cable seat of the flat cantilever arm and the sleeve seat of the inclined cantilever arm. In the existing technology, the pre-assembly of the single ear is mostly done manually, which leads to low work efficiency. Moreover, manual assembly is prone to problems such as inaccurate positioning of the assembly position and uneven locking force of the single ear, thereby reducing the product qualification rate.

[0003] In view of this, the present invention provides a pre-assembly device for a single ear of an aluminum cantilever arm. By setting up modules such as a single pre-tensioning tube module, a single pre-tightening module, a single pre-feeding tube module, and a single pre-supporting and pressing module, the pre-assembly of the single ear of the aluminum cantilever arm is automated, ensuring the accuracy of the assembly position of the cantilever arm tube and the single ear, and the uniformity of the locking force of the single ear, thereby improving the work efficiency and the product qualification rate.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] Reference Figures 1 to 7 As shown, an improved single-ear pre-assembly device for an aluminum wrist arm includes a single pre-rail module a1 and a single-ear pickup module a8. The single pre-rail module a1 is equipped with a single pre-feeding tube module a6. Multiple single pre-support clamping modules a7 are located to the side of the single pre-rail module a1, in front of the single pre-feeding tube module a6. Multiple single pre-support frame modules a2 are located in front of the single pre-support clamping module a7, and these modules are aligned on the same straight line. A single pre-tightening module a4 is located on the single pre-rail module a1 and in front of the single pre-feeding tube module a6. A single pre-pulling tube module a3 is also provided on the single pre-rail module a1. The single-ear pickup module a8 is used to grasp the single ear and transfer it between adjacent single pre-support clamping modules a7. The single pre-feeding tube module a6 is used to clamp the wrist arm tube and continue to transport it forward so that the wrist arm tube...

[0027] The single pre-support clamping module a7 is used to support and clamp the carpal tube conveyed by the single pre-feeding tube module a60. The single pre-tightening module a4 is used to move below the single ear and lock the single ear and the carpal tube. The single pre-pull tube module a3 is used to clamp the carpal tube conveyed by the single pre-feeding tube module a60 and continue to convey it forward. The single pre-support frame module a2 is used to support the carpal tube conveyed by the single pre-pull tube module a3.

[0028] In this embodiment, the "front" and "back" directions refer to... Figure 1 The direction shown is the reference. Figure 1 In the diagram, left represents front and right represents back.

[0029] 5. In this embodiment, the single ear pickup module a8 is used to grasp a single ear and transfer it between adjacent single pre-support clamping modules a7; the single pre-feeding tube module a6 is used to clamp the carpal tube and continue to feed it forward so that the carpal tube passes through and through the single ear; the single pre-support clamping module a7 is used to support and clamp the carpal tube fed by the single pre-feeding tube module a6; and the single pre-tightening module a4 is used to move to below the single ear and lock it.

[0030] The single ear and the wrist arm tube are tightly connected. The single pre-stretch tube module a3 is used to clamp the wrist arm tube conveyed by the single pre-feed tube module a6 and continue to convey it forward. The single pre-support frame module a2 is used to support the wrist arm tube conveyed by the single pre-stretch tube module a3.

[0031] In this embodiment, the single-ear pickup module a8 first picks up a single ear and transfers it between two adjacent single pre-support clamping modules a7; preferably, the single-ear pickup module a8 transfers the single ear...

[0032] The tube is transported to the space between the two single pre-support clamping modules a7 closest to the single pre-support frame module a2. Then, the single pre-feeding module a6 clamps the arm tube conveyed from the previous station and continues to convey it forward so that the arm tube passes through the single ear; when the arm tube is long enough, it can also pass through the single ear while being conveyed from the previous station, in which case the single pre-feeding module a6 only serves to clamp the arm tube and continue conveying it forward. Then, the single pre-pulling module a3 clamps the conveyed arm tube and continues to convey it forward. During the conveying of the arm tube, when the arm tube reaches the position of the pre-fitted single ear, the conveying is paused, the single pre-support clamping module a7 clamps the arm tube, and the single pre-tightening module a4 moves below the single ear to lock the single ear and the arm tube, and then the arm tube continues to be conveyed.

[0033] Compared with the prior art, this embodiment achieves automated operation of pre-assembly of single lugs of aluminum cantilever arms by setting up modules such as single pre-tensioning tube module a3, single pre-tightening module a4, single pre-feeding tube module a6, and single pre-supporting and pressing module a7. The single pre-tensioning tube module a3 and single pre-feeding tube module a6 ensure the accuracy of the assembly position of the single lug and the cantilever tube, and the single pre-tightening module a4 and single pre-supporting and pressing module a7 ensure that the locking force of the single lug is equal, thereby improving the operation efficiency and the product qualification rate.

[0034] Furthermore, refer to Figure 5 As shown, the single pre-feed tube module a6 includes a single pre-feed tube base a61 disposed on the single pre-rail module a1, a single pre-feed tube movement driver a63 disposed on the single pre-feed tube base a61 and driving the single pre-feed tube base a61 to move relative to the single pre-rail module a1, and a single pre-feed tube support a62 disposed on the single pre-feed tube base a61. The single pre-feed tube support a62 is provided with a single pre-feed tube clamping driver a64. The telescopic end of the single pre-feed tube clamping driver a64 is connected to a single pre-feed tube gripper a65. The single pre-feed tube gripper a65 is used to clamp the wrist arm tube.

[0035] Furthermore, refer to Figure 2 As shown, the single pre-support frame module a2 includes a single pre-support column a21 and a single pre-support lifting cylinder a22 disposed on the single pre-support column a21. The telescopic end of the single pre-support lifting cylinder a22 is provided with a single pre-support connecting plate a23, and the single pre-support connecting plate a23 is provided with a single pre-support roller a24. The single pre-support roller a24 is used to support the carpenter arm tube.

[0036] In this embodiment, the single pre-support lifting cylinder a22 and the single pre-support connecting plate a23 are designed to avoid interference between the single pre-support frame module a2 and the single pre-tensioning pipe module a3 during the transport of the cantilever tube.

[0037] Example 2:

[0038] Based on Example 1, referring to Figure 6As shown, the single pre-support clamping module a7 includes a single pre-support clamping column a71, a single pre-support clamping lifting driver a72 disposed on the single pre-support clamping column a71, a single pre-support clamping connecting plate a74 disposed on the telescopic end of the single pre-support clamping lifting driver a72, a single pre-support clamping roller a77 disposed on the single pre-support clamping connecting plate a74, and a single pre-support clamping roller a77 disposed on the single pre-support clamping connecting plate a74 and located on the single pre-support clamping roller a77. A single pre-support clamping actuator a75 is located on the side of 77. A single pre-support clamping block a76 is provided on the telescopic end of the single pre-support clamping actuator a75. The single pre-support clamping block a76 moves up and down relative to the single pre-support clamping roller a77 under the drive of the single pre-support clamping actuator a75 to release or clamp the wrist arm tube. The single pre-support clamping block a76 rotates relative to the single pre-support clamping actuator a75 under the drive of the single pre-support clamping actuator a75.

[0039] Furthermore, a single pre-support pressing lifting drive a72 and a single pre-support pressing connecting plate a74 are provided with a single pre-support pressing lifting plate a73, which is used to provide a sliding track for the single pre-support pressing connecting plate a74 to move up and down relative to the single pre-support pressing lifting drive a72.

[0040] In this embodiment, the reason for setting up a single pre-support clamping lifting driver a72 is that when the single pre-support clamping connecting plate a74 and its single pre-support clamping roller a77 are in the position supporting the arm tube, they will interfere with the conveying of the arm tube, especially the conveying of the arm tube equipped with a single ear. Similarly, the reason for setting up a single pre-support clamping block a76 to rotate relative to the single pre-support clamping driver a75 under the drive of the single pre-support clamping driver a75 is also to avoid interference of the single pre-support clamping module a7 with the conveying of the arm tube. The reason for setting up a single pre-support clamping block a76 to move up and down relative to the single pre-support clamping roller a77 under the drive of the single pre-support clamping driver a75 to loosen or clamp the arm tube is to ensure the stability of the arm tube when the single pre-tightening module a4 locks the single ear and the arm tube, and to prevent the arm tube from shifting due to locking.

[0041] Example 3:

[0042] Based on Example 1 or 2, refer to Figure 3As shown, the single pre-tensioned tube module a3 includes a single pre-tensioned tube base a31 disposed on the single pre-rail module a1, a single pre-tensioned tube moving driver a33 disposed on the single pre-tensioned tube base a31 and driving the single pre-tensioned tube base a31 to move relative to the single pre-rail module a1, and a single pre-tensioned tube support a32 disposed on the single pre-tensioned tube base a31. The single pre-tensioned tube support a32 is provided with a single pre-tensioned tube clamping driver a36. The single pre-tensioned tube clamping driver a36 drives the single pre-tensioned tube gripper a37 to clamp or release to hold or release the wrist arm tube.

[0043] Furthermore, the single pre-tensioned tube support a32 is provided with a single pre-tensioned tube connecting plate a34, and the single pre-tensioned tube clamping driver a36 is provided on the single pre-tensioned tube support a32 through the single pre-tensioned tube connecting plate a34.

[0044] Furthermore, the single pre-tensioned tube connecting plate a34 is provided with a single pre-tensioned tube rotary driver a35, and the single pre-tensioned tube clamping driver a36 is connected to the single pre-tensioned tube rotary driver a35. The single pre-tensioned tube rotary driver a35 drives the single pre-tensioned tube clamping driver a36 to rotate, thereby driving the wrist arm tube held by the single pre-tensioned tube gripper a37 to rotate.

[0045] In this embodiment, the reason why the single pre-tensioned tube gripper a37 is set on the single pre-tensioned tube bracket a32 through the single pre-tensioned tube connecting plate a34 is to avoid interference from the single pre-support clamping module a7 and the single pre-support frame module a2 on the single pre-tensioned tube module a3 when the single pre-tensioned tube module a3 is conveying the cantilever tube. The reason why the single pre-tensioned tube rotary driver a35 is set to drive the single pre-tensioned tube clamping driver a36 to rotate, thereby driving the cantilever tube held by the single pre-tensioned tube gripper a37 to rotate, is because the single ear assembled on the cantilever tube has a directional requirement, that is, some of the bolts of the single ear face up and some face down. The single pre-tightening module a4 can only lock the bolts facing down. Therefore, when the bolts of the single ear need to face up, the single pre-tensioned tube rotary driver a35 drives the single pre-tensioned tube clamping driver a36 to rotate, thereby driving the cantilever tube held by the single pre-tensioned tube gripper a37 to rotate. At this time, after locking the bolts of the single ear, the cantilever tube is rotated again, and the bolts of the single ear meet the requirement of facing up.

[0046] Example 4:

[0047] Based on any of the foregoing embodiments, refer to Figure 4As shown, it also includes a single pre-fixed support module a5, which is located on the side of the single pre-rail module a1 near the end of the single pre-support clamping module a7. The single pre-fixed support module a5 and the multiple single pre-support clamping modules a7 are located on the same straight line. The single pre-fixed support module a5 is equipped with a single pre-fixed support marking machine a57, which is used to mark the cartilage tube.

[0048] Furthermore, the single pre-fixed support module a5 includes a single pre-fixed support column a51, a single pre-fixed support connecting plate a52 and a single pre-fixed support mounting plate a54 disposed on the single pre-fixed support column a51. The single pre-fixed support connecting plate a52 is provided with a single pre-fixed support roller a53 for supporting the arm tube. The single pre-fixed support mounting plate a54 is provided with a single pre-fixed support telescopic actuator a55. The telescopic end of the single pre-fixed support telescopic actuator a55 is provided with a single pre-fixed support moving plate a56. The single pre-fixed support marking machine a57 ​​is disposed on the single pre-fixed support moving plate a56.

[0049] In this embodiment, the single pre-fixed support marking machine a57 ​​can mark information such as the installation position, structural features, specifications, and production date of the aluminum cantilever arm on the cantilever tube, thereby facilitating the subsequent use and maintenance of the aluminum cantilever arm; the single pre-fixed support roller a53 can be used to support the cantilever tube; the single pre-fixed support telescopic driver a55 can adjust the distance between the single pre-fixed support marking machine a57 ​​and the cantilever tube, thereby facilitating marking, and can also extend to mark when marking is needed and retract when marking is not needed to avoid interference with the conveying of the cantilever tube.
