Description

Technical Field

[0001] The invention relates to the technical field of cable bridge processing, in particular to a cable bridge welding device. Background Art

[0002] Cable trays are divided into trough-type cable trays, tray-type cable trays, ladder-type cable trays, grid-type cable trays and other structures. They can be erected independently or laid on various buildings and pipe gallery brackets. They have the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. For the cable trays installed in the open air outside the building, if they are near the seaside or in a corrosion zone, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion and high impact strength. However, the overall length of the cable tray is limited after all. Therefore, during the erection, if there is a place with a long erection path, multiple cable trays need to be connected in sequence by welding, so as to extend the overall length of the cable tray.

[0003] According to a Chinese patent with application publication number CN116586833A, a cable tray welding device is disclosed. By touching the magnetic card block during the sliding process of the bridge, the magnetic card block drives the positioning plate to rotate into the positioning groove: the positioning plate is rotated to fit with the surface of the bridge, and the bridge slides toward the welding area until it contacts the limit table, and is transported to the welding area, thereby achieving a positioning effect. However, during the welding process, the above-mentioned device still lacks the function of calibrating the end of the bridge. If the end of the bridge is deformed or curled, the smoothness of the weld and the density of the weld cannot be guaranteed. For this reason, we propose a cable tray welding device to solve the above-mentioned technical problems. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, by starting the hydraulic cylinder, the upper and lower pile feet are brought closer to the middle. During the movement of the upper and lower pile feet toward the middle, the upper and lower positioning plates are first abutted against the top and bottom of the bridge frame, and as the upper and lower calibration tables continue to move toward the middle, the telescopic rod moves toward the inside of the telescopic groove, thereby compressing the reset spring, and further under the action of the rebound force of the reset spring, the telescopic rod is pushed in the reverse direction, so that the positioning plate is tightly abutted against the surface of the bridge frame, thereby achieving the upper and lower positioning effect of the upper and lower positioning plates on the tripod, avoiding the problem of displacement of the tripod during welding, and ensuring the beauty of the lines of the bridge frame welding.

[0020] 2. In the present invention, the upper and lower calibration platforms are brought closer to each other, further driving the upper and lower combing plates to move toward the middle, so that the upper and lower combing plates are respectively closer to the top of the bridge frame and the bottom of the foot frame, until the upper and lower combing plates are in contact with the top of the bridge frame and the bottom of the bridge frame, and as the two calibration platforms continue to move toward the middle, the downward thrust of the connecting rod on the combing plate is subjected to the reverse force of the bridge frame surface, so that the connecting rod pushes the combing plate to slide along the surface of the bridge frame, and as the calibration platform gradually approaches the bridge frame, the connecting rod rotates along the inside of the first hinge groove, and the combing plate moves toward the direction of the positioning frame, further driving the vertical sliding rod to move together along the inside of the linear sliding block, causing the fastening spring to compress and accumulate force, and the combing plate is pressed down by the rebound force generated by the fastening spring, so that the combing plate is always tightly attached to the surface of the bridge frame, and then when the combing plate slides along the surface of the bridge frame, the bridge frame is pressed flat, and the curled portion is flattened, thereby ensuring the fit of the left and right bridge frame interfaces, and further improving the aesthetics and welding quality of the bridge frame after welding.

[0021] 3. In the present invention, the two calibration tables above move downward, so that the front and rear thrust plates drive the front and rear thrust pins to move downward together. The downward movement of the two thrust pins distributed front and back will drive the two torsion sleeves to rotate under the action of the spiral thrust of the two spiral grooves distributed front and back. It should be noted that the spiral direction of the two front and rear spiral grooves, so the two front and rear spiral grooves are under the action of the downward movement of the two thrust pins, and the two torsion sleeves rotate in opposite directions. The rotation of the two torsion sleeves drives the positioning vertical shaft to rotate along the two bearing seats through the vortex spring, and the rotation of the positioning vertical shaft also drives the positioning pressure head to rotate along the axial direction of the positioning vertical shaft through the arc arm, so that the front and rear positioning pressure heads move toward the middle, and the front and rear of the bridge are positioned to ensure the lateral stability of the bridge.

[0022] 3. In the present invention, after the positioning pressure head abuts against the surface of the bridge frame, if the thrust pin continues to move downward, the torsion sleeve will continue to rotate, which will cause the vortex spring to compress and accumulate force, thereby not continuously pushing the positioning vertical shaft to rotate, thereby preventing the positioning pressure head from clamping and deforming the bridge frame. At the same time, the rebound force generated by the vortex spring is transmitted to the positioning pressure head through the positioning vertical shaft and the arc arm, thereby ensuring sufficient clamping and positioning effect on the bridge frame.

[0041] The specific embodiment of the present invention is as follows: on the one hand, by starting the hydraulic cylinder 301, the upper and lower pile feet 302 are brought closer to the middle. During the movement of the upper and lower pile feet 302 toward the middle, the upper and lower positioning plates 3016 first abut against the top and bottom of the bridge frame, and as the upper and lower calibration platforms 303 continue to move toward the middle, the telescopic rod 3014 moves toward the inside of the telescopic slot 3013, thereby compressing the reset spring 3015. Further, under the action of the rebound force of the reset spring 3015, the telescopic rod 3014 is pushed in the reverse direction, so that the positioning plates 3016 are tightly abutted against the surface of the bridge frame, achieving the upper and lower positioning effect of the upper and lower positioning plates 3016 on the tripod, avoiding the problem of displacement of the tripod during welding, and ensuring the aesthetic lines of the bridge frame welding. On the other hand, since the upper and lower calibration platforms 303 are close to each other, the upper and lower combing plates 306 are further driven to move toward the middle, so that the upper and lower combing plates 306 are respectively close to the top of the bridge frame and the bottom of the tripod, until the upper and lower combing plates 306 are close to each other. The sorting plate 306 is in contact with the top and bottom of the bridge frame, and as the two calibration platforms 303 continue to move toward the middle, the downward thrust of the connecting rod 305 on the combing plate 306 is subjected to the reverse force of the bridge surface, causing the connecting rod 305 to push the combing plate 306 to slide along the surface of the bridge frame, and as the calibration platform 303 gradually approaches the bridge frame, the connecting rod 305 rotates along the inside of the first hinge groove 304, and the combing plate 306 moves toward the direction of the positioning frame 308, further driving the vertical slide bar 3011 to move along the inside of the linear slider 3010, causing the fastening spring 3012 to compress and accumulate force, and the combing plate 306 is pressed down by the rebound force generated by the fastening spring 3012, so that the combing plate 306 is always tightly attached to the surface of the bridge frame, and then when the combing plate 306 slides along the surface of the bridge frame, the bridge frame is pressed flat, and the curled part is pushed flat, ensuring the fit of the left and right bridge interface, and further improving the aesthetics and welding quality of the bridge frame after welding.

[0042] Embodiment 3: The horizontal positioning component 400 includes two bearing seats 401 fixedly mounted on the surface of the welding frame 100, the two bearing seats 401 are distributed up and down, and the two bearing seats 401 distributed up and down have a positioning vertical shaft 402 installed inside to rotate together, and an arc arm 403 is fixedly installed on the outer wall of the positioning vertical shaft 402, and the arc arm 403 is located between the upper and lower bearing seats 401, and a positioning pressure head 404 is fixedly installed on one end of the arc arm 403 away from the positioning vertical shaft 402, and the positioning pressure head 404 is located at the upper and lower Between the two calibration platforms 303, a buffer rubber pad is provided on the outer wall of the positioning pressure head 404, a torsion sleeve 406 is provided on the upper part of the outer wall of the positioning vertical shaft 402, and a spiral groove 407 is provided on the outer wall of the torsion sleeve 406, wherein two thrust plates 408 distributed front and back are fixedly installed on one side of the upper calibration platform 303 close to the pile foot 302, and thrust pins 409 are fixedly installed on the side away from the two thrust plates 408, and the outer wall of the thrust pin 409 is slidably connected with the inner wall of the spiral groove 407;

[0043] The top wall of the torsion sleeve 406 is rotatably connected to the top of the positioning vertical shaft 402 via a bearing, and the inner diameter of the torsion sleeve 406 is larger than the outer diameter of the positioning vertical shaft 402. A vortex spring 405 is fixedly installed between the outer wall of the positioning vertical shaft 402 and the inner wall of the torsion sleeve 406.

[0044] Specifically, in this embodiment, when the two calibration platforms 303 above move downward, the two front and rear thrust pins 409 are driven to move downward together through the two front and rear thrust plates 408. The downward movement of the two front and rear thrust pins 409 will drive the two torsion sleeves 406 to rotate under the action of the spiral thrust of the two front and rear spiral grooves 407. It should be noted that the spiral direction of the two front and rear spiral grooves 407 is such that the two front and rear spiral grooves 407 are under the action of the downward movement of the two thrust pins 409, and the two torsion sleeves 406 rotate in opposite directions. The rotation of the two torsion sleeves 406 drives the positioning vertical shaft 402 to rotate along the two bearing seats 401 through the vortex spring 405, and the rotation of the positioning vertical shaft 402 is also driven by the vortex spring 405. The arc arm 403 drives the positioning pressure head 404 to rotate along the axial direction of the positioning vertical axis 402, so that the front and rear positioning pressure heads 404 move toward the middle, position the front and rear of the bridge frame, and ensure the lateral stability of the bridge frame. After the positioning pressure head 404 abuts against the surface of the bridge frame, if the thrust pin 409 continues to move downward, the torsion sleeve 406 will continue to rotate. At this time, the vortex spring 405 will be compressed and stored, so that it will not continuously push the positioning vertical axis 402 to rotate, avoiding the positioning pressure head 404 from clamping and deforming the bridge frame. At the same time, the rebound force generated by the vortex spring 405 is transmitted to the positioning pressure head 404 through the positioning vertical axis 402 and the arc arm 403, which can ensure that there is sufficient clamping and positioning effect on the bridge frame.

[0045] When the cable tray welding device of the present invention is working, two cables to be welded are respectively inserted from the left and right sides of the welding frame 100 between the upper and lower calibration components 300, and the welding ends of the two cables are made to abut against each other;

[0046] Then, all the hydraulic cylinders 301 are started, so that the upper and lower pile feet 302 are brought closer to the middle. During the movement of the upper and lower pile feet 302 toward the middle, the upper and lower positioning plates 3016 first contact the top and bottom of the bridge frame, and as the upper and lower calibration platforms 303 continue to move toward the middle, the telescopic rod 3014 moves toward the inside of the telescopic slot 3013, thereby compressing the reset spring 3015. Further, under the action of the rebound force of the reset spring 3015, the telescopic rod 3014 is pushed in the reverse direction, so that the positioning plates 3016 are tightly contacted with the surface of the bridge frame, achieving the upper and lower positioning effect of the upper and lower positioning plates 3016 on the tripod, avoiding the displacement problem of the tripod during welding, and ensuring the aesthetic lines of the bridge frame welding;

[0047] At the same time, as the upper and lower calibration platforms 303 approach each other, the upper and lower combing plates 306 are further driven to move toward the middle, so that the upper and lower combing plates 306 approach the top of the bridge and the bottom of the foot frame respectively, until the upper and lower combing plates 306 hit the top of the bridge and the bottom of the bridge, and as the two calibration platforms 303 continue to move toward the middle, the downward thrust of the connecting rod 305 on the combing plate 306 is acted upon by the reverse force of the bridge surface, so that the connecting rod 305 pushes the combing plate 306 to slide along the surface of the bridge, and as the calibration platform 303 gradually approaches the bridge, the connecting rod 305 moves along the first hinge The groove 304 rotates inside, and the combing plate 306 moves toward the positioning frame 308, further driving the vertical slide bar 3011 to move along the inside of the linear slide block 3010, causing the fastening spring 3012 to compress and accumulate force, and the combing plate 306 is pressed down by the rebound force generated by the fastening spring 3012, so that the combing plate 306 is always tightly attached to the surface of the bridge frame, and then when the combing plate 306 slides along the surface of the bridge frame, the bridge frame is pressed flat, and the curled part is flattened, ensuring the fit of the left and right bridge frame interfaces, and further improving the aesthetics and welding quality of the bridge frame after welding;

[0048] When the two calibration platforms 303 above move downward, the two front and rear thrust pins 409 are driven to move downward together through the two front and rear thrust plates 408. The downward movement of the two front and rear thrust pins 409 will drive the two torsion sleeves 406 to rotate under the action of the spiral thrust of the two front and rear spiral grooves 407. It should be noted that the spiral directions of the two front and rear spiral grooves 407 are such that the two front and rear spiral grooves 407, under the action of the downward movement of the two thrust pins 409, the two torsion sleeves 406 rotate in opposite directions. The rotation of the two torsion sleeves 406 drives the positioning vertical shaft 402 to rotate along the two bearing seats 401 through the vortex spring 405, and the rotation of the positioning vertical shaft 402 is also driven by the arc arm 4 03 drives the positioning pressure head 404 to rotate along the axial direction of the positioning vertical axis 402, so that the front and rear positioning pressure heads 404 move toward the middle, position the front and rear of the bridge frame, and ensure the lateral stability of the bridge frame. When the positioning pressure head 404 abuts against the surface of the bridge frame, if the thrust pin 409 continues to move downward, the torsion sleeve 406 will continue to rotate. At this time, the vortex spring 405 will be compressed and stored, so that it will not continuously push the positioning vertical axis 402 to rotate, avoiding the positioning pressure head 404 from clamping and deforming the bridge frame. At the same time, the rebound force generated by the vortex spring 405 is transmitted to the positioning pressure head 404 through the positioning vertical axis 402 and the arc arm 403, which can ensure that the bridge frame has sufficient clamping and positioning effect.

[0049] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the invention.
