Description

Technical Field

[0001] The invention relates to the technical field of cable bridge welding, and in particular to a mobile welding device suitable for cable bridges. Background Art

[0002] Cable trays are rigid structural systems that closely support cables, consisting of trough-type, tray-type or ladder-type straight sections, bends, tees, and crosses, as well as brackets and hangers. Cable trays are divided into trough-type, tray-type, ladder-type, and grid-type structures, and are composed of brackets, brackets, and installation accessories. The cable trays in buildings can be erected independently or attached to various buildings and pipe gallery brackets. They should have the characteristics of simple structure, beautiful shape, flexible configuration, and easy maintenance. All parts must be galvanized. For cable trays installed in the open air outside buildings, if they are near the sea or in a corrosion zone, the material must have the physical properties of corrosion resistance, moisture resistance, good adhesion, and high impact resistance.

[0003] The purpose of welding partitions inside the cable tray duct is to distinguish cables with different uses inside the duct. When two or more cables with different uses are laid inside the same bridge at the same time, partitions need to be welded inside the cable tray duct to separate them in order to avoid mutual interference.

[0004] In the prior art, when welding partitions inside cable tray ducts, most of the time, manual welding is still adopted, which is time-consuming and labor-intensive, and the smoke generated by welding is also likely to cause harm to the health of workers; in the prior art, a device that uses a robotic arm to drive the welding equipment to automatically weld has also been developed, but after the partitions are welded, the welding slag and other impurities generated during the welding process still need to be manually cleaned by the workers, which still increases the labor of the workers and cannot achieve fully automated operation.

[0040] As a technical optimization solution of the present invention, the grinding mechanism includes two round blocks 30, which are respectively mounted on the outer walls of the two round rods 29. The outer walls of the two round blocks 30 are provided with round grooves 32, and the insides of the two round grooves 32 are both equipped with electric sliders 33, and the ends of the two electric sliders 33 away from the round grooves 32 are both equipped with connecting rods 34.

A second double-headed screw is preset inside the two third chutes 36, and one end of the two second double-headed screws is connected to the preset output end of the first servo motor, so that the two second double-headed screws can be driven to rotate inside the corresponding third chutes 36, and the two third sliders 38 can be driven to move and adjust in the direction of approaching or moving away from each other; and a second servo motor is preset on the outer wall of one side of the two third sliders 38, and the output ends of the two second servo motors are respectively connected to the rotating parts of the two rectangular strips, so that the two rectangular strips can be driven to rotate and adjust between the two corresponding third sliders 38.

[0043] As a technical optimization solution of the present invention, the second driving mechanism includes a driving motor 16 installed on the outer wall of the two fixed plates 8 away from each other, the output ends of the two driving motors 16 are both installed with a first bevel gear 17, the outer walls of the two fixed plates 8 away from each other are both rotatably installed with a driving block 18, the outer walls of the two driving blocks 18 away from each other on the side of the fixed plate 8 are both installed with a second bevel gear 19, and the two first bevel gears 17 are meshed with their corresponding second bevel gears 19. While the driving motor 16 drives the first bevel gear 17 to rotate, it can synchronously drive the second bevel gear 19 and the driving block 18 to rotate.

[0044] As a technical optimization solution of the present invention, the inner walls on both sides of the two fixed plates 8 are provided with third grooves 20, and the driving plates 23 are slidably installed inside the two third grooves 20. The top ends of the two driving plates 23 are connected to the inner walls of the corresponding third grooves 20 through springs 22, and the bottoms of the two driving plates 23 are connected to the mobile frame 15 through the third electric telescopic rod 24, and the center position of the mobile frame 15 is installed with a pressure rod 37. When the driving block 18 rotates, it will push against the top of the driving plate 23 below, drive multiple springs 22 to elastically extend, and drive the third electric telescopic rod 24 and the mobile frame 15 below to move downward, and after the driving block 18 rotates and resets, it drives the mobile frame 15 and other components to move upward and reset, thereby achieving the effect of driving the mobile frame 15 to move up and down.

[0045] In the present invention, when the user uses the device, after placing the cable tray directly below the movable frame 15, the position of the two second sliders 13 inside the second slide slot 12 is adjusted according to the width of the cable tray, driving the positions of the multiple components below to be adjusted together, and then the telescopic ends of the two first electric telescopic rods 5 are controlled to extend downward together, driving the multiple components below to move downward together, until the two welding heads 7 abut against the bottom surface of the cable tray wire duct, and then the two movable plates 14 are controlled to move in a direction of approaching, driving the two welding heads 7 and the grinding block 31 and multiple components below. Move together in the direction of approaching each other, according to the thickness of the partition to be welded, control the two electric sliders 33 to move inside the corresponding circular groove 32, drive the two connecting rods 34 and the grinding block 31 to move and adjust in the direction of approaching each other, so that the distance between the two grinding blocks 31 is adapted to the thickness of the partition. At this time, the partition to be welded can be placed between the two grinding blocks 31, and the two grinding blocks 31 can naturally support the outer walls on both sides of the partition and ensure that the partition is located in the center position of the cable tray duct, which is convenient for the subsequent welding work between the partition and the cable tray duct.

[0046] At the same time, when the partition is placed in the center position of the cable tray duct, if it is necessary to grind the bottom end of the partition to be welded, so as to facilitate the subsequent welding between the partition and the cable tray duct, one of the sliding blocks 28 can be controlled to move in the direction close to the other sliding block 28 inside the corresponding through groove 27 until the two sliding blocks 28 are in the same straight line. At this time, the two grinding blocks 31 are also in a close state. The two grinding blocks 31 are controlled to rotate, and one end of the partition is placed between the two grinding blocks 31. With the help of the two grinding blocks 31, the bottom end of the partition to be welded can be grinded, and as the external manual or feeding mechanism pushes the partition to move, the two grinding blocks 31 can be used to comprehensively grind the bottom end of the partition to be welded, which is beneficial to the subsequent welding work. After the two grinding blocks 31 have completed the grinding of the bottom end of the partition, one of the sliding blocks 28 is controlled to drive the corresponding grinding block 31 to move and reset, so that it continues to support both sides of the partition.

[0047] After the partition is located in the center position of the cable tray duct, the bottom ends of the two welding heads 7 are in contact with the two ends of the bottom of the partition, and the telescopic ends of the third electric telescopic rods 24 are controlled to extend downward, so that the movable frame 15 is driven to move downward, so that the pressure rod 37 set in the center position of the movable frame 15 can press and fix the partition downward, and then the two rectangular strips are controlled to drive the two metal wire brushes 9 to rotate upward together to a horizontal state, and because the two metal wire brushes 9 are made of metal filaments, they will not affect the subsequent movement of the round rod 29, and with the help of two sliding blocks 28 moving in the direction of approaching, the two welding heads 7 are driven to move together, so that the two welding heads 7 can perform welding work together, and the partition can be welded inside the cable tray duct conveniently and quickly, thereby improving welding efficiency; and at this time, the two metal wire brushes 9 located at the bottom of the movable frame 15 in a horizontal state can block the top of the two welding heads 7 to prevent sparks generated by welding from splashing upward, thereby improving welding safety.

[0048] After the partition is welded inside the cable tray of the cable bridge, the telescopic ends of the two second electric telescopic rods 35 can be controlled to extend downward together, thereby driving the two grinding blocks 31 to contact the welding parts of the partition and the cable tray. As the two grinding blocks 31 are controlled to rotate and the grinding blocks 31 are driven to move with the help of the two sliding blocks 28, the welding parts of the partition and the cable tray are polished and cleaned, the excess parts produced by welding are polished and smoothed, and the aesthetics of the welding parts are improved.

[0049] After the two grinding blocks 31 have finished grinding the welding parts, the telescopic ends of the two first electric telescopic rods 5 can be controlled to retract upward, and the telescopic ends of the multiple third electric telescopic rods 24 can be controlled to extend downward, driving the mobile frame 15 to move downward to the bottom of the two welding heads 7. At this time, the pressure rod 37 in the center position inside the mobile frame 15 is located directly above the partition. By controlling the two driving motors 16 to start, the driving block 18 is driven to rotate, so that the driving block 18 continuously pushes and resets the driving plate 23 below during the rotation, and drives the pressure rod 37 to continuously vibrate and knock the top of the welded partition. On the one hand, the stability of the partition after welding can be tested, and on the other hand, the excess impurities on the surface of the welding part of the partition and the cable tray trunking can be vibrated off, which is convenient for subsequent cleaning of impurities.

[0050] After the welding quality test of the partition is completed, there will be debris generated by grinding and welding slag generated by welding on both sides of the partition. At this time, the telescopic ends of the multiple third electric telescopic rods 24 can be controlled to retract upward and reset, and the movable frame 15 can be driven to move upward and reset, and then the two rectangular strips are controlled to drive the corresponding wire brushes 9 to rotate downward to a vertical state, so that the two wire brushes 9 are respectively located on both sides of the partition, and the bottom ends of the two wire brushes 9 are in contact with the bottom surface of the cable tray of the cable tray. With the help of the two corresponding third sliders 38, the two wire brushes 9 are driven to move in the direction of approaching, and the impurities accumulated on both sides of the partition are pushed to a position close to the partition, and the first slider 11 is moved to one end inside the first slide 2, and the two wire brushes 9 are driven to clean out the impurities cleaned near the two sides of the partition from the inside of the cable tray cable tray, so as to achieve the effect of automatically removing impurities generated by welding and grinding, so that the degree of automation of the device is high, and the applicability of the entire device in actual use is improved.

[0051] After the welding work of the partition inside the cable tray duct is completed, the cable tray is removed from the bottom of the movable frame 15. At this time, the movable frame 15 is still located below the two welding heads 7. The two rectangular strips can be controlled to drive the two wire brushes 9 to rotate upward to a horizontal state together, and then the two movable plates 14 are controlled to move in opposite directions, driving the two welding heads 7 and the grinding block 31 to move to the center of the two rectangular grooves inside the movable frame 15 respectively, and the telescopic ends of the multiple third electric telescopic rods 24 are controlled to retract upward, thereby driving the movable frame 15 and the two wire brushes 9 below to contact the two welding heads 7 and the grinding block 31. At this time, the driving motor 16 can be controlled again to drive the driving block 18 to rotate, so that the two wire brushes 9 under the movable frame 15 machine continuously move up and down, and the two wire brushes 9 can continuously rub against the outer walls of the two welding heads 7 and the grinding block 31 while moving up and down, so that the debris attached to the outer walls of the two welding heads 7 and the grinding block 31 can be cleaned and removed.

[0052] The two sliding blocks 28 can also be synchronously controlled to move back and forth inside the corresponding through grooves 27, so that the two welding heads 7 and the grinding blocks 31 can be in frictional contact with the two wire brushes 9 laterally, further improving the cleaning effect of the outer walls of the two welding heads 7 and the grinding blocks 31; and while the two wire brushes 9 move up and down, the impurities mixed inside them can also be shaken away, which is convenient for the subsequent use of the two wire brushes 9.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.
