Description

Technical Field

[0001] The utility model relates to the technical field of cross-arm assembly welding, in particular to a turnover device for cross-arm assembly welding. Background Art

[0002] In power transmission, electric energy needs to be transmitted through cables. However, cables cannot be laid infinitely long. Especially during high-altitude transmission, support devices need to be set at certain intervals. Electric power poles are commonly used support devices. At the same time, many distribution devices are also installed on electric power poles, and electric power poles play an important role in the normal operation of the power grid. As an important part of the electric power pole, the main function of the cross-arm is to fix the conductors of the power line in the air to ensure the stability and safety of the conductors. The solid structure and reasonable layout of the cross-arm can effectively support the weight of the conductors and prevent the conductors from shifting or sagging due to factors such as wind force and gravity, thus ensuring the normal operation of the power line.

[0003] During the cross-arm assembly process, through precise cooperation and connection, the tight combination between each component can be ensured, thus forming a solid overall structure. This stability is crucial for supporting conductors such as power lines and lightning protection lines, and can prevent safety accidents caused by structural loosening or deformation. Through assembly, the cross-arm can disperse and bear the weight and tension from the conductors, improving the overall load-bearing capacity. This is of great significance for ensuring the stable operation of the power line and extending the service life of the cross-arm.

[0004] After the cross-arm is assembled, the seams need to be welded, and in addition, some necessary connectors such as hanging line plates, footrests, handrails, jumper plates, and anti-bird thorn devices need to be welded on the four sides of the assembled cross-arm. However, there are great difficulties in welding at present. Generally, manual labor is used for turnover. Since the assembled cross-arm is too large and heavy, it is very difficult to turn it over when welding the other side, and at the same time, dimensional deviation may occur during the turnover process. Therefore, using the current turnover method is slow, the welding auxiliary time is very long, the welding efficiency is low, and it is time-consuming and laborious.

[0005] Therefore, there is an urgent need in the art for a turnover device for cross-arm assembly welding that saves time and effort, has a fast turnover speed, and improves the turnover efficiency. Summary of the Invention

[0006] The purpose of the utility model is to provide a turnover device for cross-arm assembly welding to solve the problems existing in the above-mentioned prior art. During cross-arm assembly welding, it can save time and effort, have a fast turnover speed, a more appropriate turnover angle, and improve production efficiency.

[0007] To achieve the above purpose, the utility model provides the following solutions:

[0008] The utility model provides a turnover device for cross-arm assembly welding, which comprises a workbench and a turnover assembly. The workbench is supported by a support assembly. The turnover assembly includes a turnover frame and a plurality of clamping assemblies. The turnover frame is located on one side of the workbench and its lower end is hinged to the support assembly. The clamping assemblies are located at the top of the turnover frame and are movably connected to the turnover frame.

The fixed end of the second hydraulic cylinder is connected to the connecting bracket, and the movable end of the second hydraulic cylinder is connected to the rotating shaft.

[0014] Preferably, two first limiting legs are hinged to the side of the turnover frame away from the workbench, and a second limiting leg is hinged to one of the second clamping jaws farthest from the control device.

[0017] The utility model has achieved the following beneficial technical effects compared with the prior art:

[0018] 1.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0027] The present utility model provides a turning device for cross-arm assembly welding, as Figure 1 - Figure 2As shown in the figure, it includes a workbench 1, and the workbench 1 is supported by a support assembly. The support assembly includes a horizontal support frame 3 and several support columns 4. The horizontal support frame 3 and several support columns 4 are fixedly connected by welding or other means to form a support frame structure, making the support assembly more stable. The flipping frame 2 is located on one side of the workbench 1, and the lower end of the flipping frame 2 is hinged to the lower part of several support columns 4, so that the flipping frame 2 can rotate relative to the support columns 4. The upper end surface of the flipping frame 2 is basically flush with the workbench 1, ensuring the supporting force for the paired cross arms. Several sleeves 6 arranged evenly along the length direction are fixedly connected to the upper end of the flipping frame 2 by welding or other means. The rotating shaft 7 passes through several sleeves 6 in sequence and is movably connected to the sleeves 6, so that the rotating shaft 7 can rotate within the sleeves 6. Several clamping assemblies are evenly fixedly connected to the rotating shaft 7, and the rotation of the rotating shaft 7 will drive the rotation of the clamping assemblies. The clamping assembly includes a first clamping claw 8 and a second clamping claw 9 which are fixedly connected. The first clamping claw 8 and the second clamping claw 9 are arranged at a right angle. When welding, the paired cross arms are placed between the first clamping claw 8 and the second clamping claw 9. When the flipping frame 2 is in the natural state, the first clamping claw 8 is in the horizontal direction, that is, when not flipped, the flipping frame 2 is in the vertical direction, and the paired cross arms are located above the first clamping claw 8.

[0028] The fixed end of the first hydraulic cylinder 10 is connected to the side of the horizontal support frame 3 away from the flipping frame 2, and the movable end of the first hydraulic cylinder 10 is connected to the flipping frame 2. When the first hydraulic cylinder 10 is started, it can drive the flipping frame 2 to rotate relative to the support assembly in the direction away from the workbench 1. The second hydraulic cylinder 11 is fixedly connected to the flipping frame 2 through a connecting bracket 12. When the flipping frame rotates driven by the first hydraulic cylinder 10, it will drive the connecting bracket 12 to rotate, and then drive the second hydraulic cylinder 11 to rotate. The fixed end of the second hydraulic cylinder 11 is connected to the connecting bracket 12, and the movable end of the second hydraulic cylinder 11 is connected to the rotating shaft 7. When the second hydraulic cylinder 11 is started, it can drive the rotation of the rotating shaft 7 within the sleeves 6, and then drive the clamping assemblies on the rotating shaft 7 to rotate.

[0029] The control device 5 is located inside one end of the horizontal support frame 3, making the structure more compact and playing a protective role for the control device 5. Two first limiting legs 13 are hinged to the side of the flipping frame 2 away from the workbench 1. When the first hydraulic cylinder 10 drives the flipping frame 2 to rotate, the two first limiting legs 13 will be driven to rotate. After the two first limiting legs 13 touch the ground, the flipping frame 2 stops rotating and the movable end of the first hydraulic cylinder 10 stops moving, restricting the flipping frame 2 at this position. A second limiting leg 14 is hinged to one of the second clamping claws 9 furthest from the control device. The second limiting leg 14 can rotate relative to the clamping assembly. When the second hydraulic cylinder 11 drives the rotating shaft 7 to rotate, the rotating shaft 7 will drive the clamping assembly to rotate. After the second limiting leg 14 touches the ground, the rotating shaft 7 stops rotating and the movable end of the second hydraulic cylinder 11 stops moving, restricting the rotating shaft 7 at this position. By providing two first limiting legs 13 and one second limiting leg 14, when the clamping assembly flips, it is respectively limited at a certain angle, indirectly controlling the stroke of the hydraulic cylinder, making the movement of the movable end of the hydraulic cylinder more accurate, with a simple structure and convenient operation. Moreover, the two first limiting legs 13 and the second limiting leg 14 achieve three-point support for the paired cross arm after flipping, making the support more stable.

[0030] The flipping device for cross-arm assembly welding provided by the utility model, in the specific application process, places the assembled cross-arm on the workbench 1. At this time, the flipping frame 2 is in the vertical direction, the first clamping jaw 8 is in the horizontal direction, and the assembled cross-arm is above the first clamping jaw 8. At this time, welding operations can be performed on the exposed side of the assembled cross-arm. After the welding of the exposed side is completed and it is necessary to flip the assembled cross-arm to weld the hidden side, the first hydraulic cylinder 10 is started through the control device 5. The first hydraulic cylinder 10 will drive the flipping frame 2 to rotate relative to the support assembly. The rotation of the flipping frame 2 will drive the rotation of the second hydraulic cylinder 11, two first limiting legs 13, the second limiting leg 14, and the clamping assembly. The assembled cross-arm will rotate with the clamping assembly. When it rotates to a certain angle and the two first limiting legs 13 contact the ground, the movable end of the first hydraulic cylinder 10 stops moving. At this time, the assembled cross-arm has been rotated by a certain angle from the horizontal direction. Then, the second hydraulic cylinder 11 is started through the control device 5. The second hydraulic cylinder 11 will drive the rotating shaft 7 to rotate, and the rotating shaft 7 will drive the clamping assembly to rotate accordingly. The assembled cross-arm will rotate with the clamping assembly. When the second limiting leg 14 contacts the ground, the movable end of the second hydraulic cylinder 11 stops moving. At this time, the hidden side of the assembled cross-arm is exposed, and welding operations can be performed on it, completing the flipping of the assembled cross-arm. This flipping device realizes the flipping of the assembled cross-arm by using the first hydraulic cylinder 10 and the second hydraulic cylinder 11, and the assembled cross-arm can be flipped twice, making the flipping angle more appropriate. The staff can start the hydraulic cylinder to work according to requirements such as the welding position, improving the welding efficiency. Compared with the prior art where manual labor is used for flipping, it saves time and effort, improves the flipping speed and efficiency, and avoids size deviation caused by offset after flipping, improving the welding rate.

[0031] After the welding of the hidden side of the assembled cross-arm is completed and the flipping device is reset, first manually close the second hydraulic cylinder 11. The return stroke of the movable end of the second hydraulic cylinder 11 will drive the rotating shaft 7 to rotate, and at the same time drive the clamping assembly to rotate towards the side close to the workbench 1. After the second hydraulic cylinder 11 stops moving, manually close the first hydraulic cylinder 10. The return stroke of the movable end of the first hydraulic cylinder 10 will drive the flipping frame 2 to rotate towards the workbench 1, thereby resetting the flipping frame 2.

[0032] In this embodiment, a first workbench groove 15 is provided at the position of the workbench 1 opposite to several support columns 4. A support column groove 16 is provided at the upper end of the support column 4. The first workbench groove 15 communicates with the support column groove 16 for accommodating the first clamping jaw 8. In the natural state, the first clamping jaw 8 is accommodated in the first workbench groove 15 and the support column groove 16, ensuring the safety of the working environment.

[0033] In this embodiment, a second workbench groove 17 is provided at one end of the workbench 1 close to the control device 5, and the second workbench groove 17 is used to accommodate the second hydraulic cylinder 11. This makes the structure more compact and plays a role in protecting the second hydraulic cylinder 11.

[0034] The present utility model uses specific examples to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation on the present utility model.
