Description

Technical Field

[0001] This invention relates to the field of welding technology, and more specifically to an automated welding equipment for steel joints. Background Technology

[0002] In engineering, large steel structures require welding of various steel nodes during assembly. Since there are many steel nodes in different locations, including some at high altitudes, manual welding equipment must be carried up to the beams and columns for welding, which is not only very laborious but also poses certain dangers.

[0003] Chinese patent (CN115106612A) discloses a welding device for beam-column joints in steel-concrete composite structures, including a linkage frame, an electric wire, and a welding torch. The electric wire is located inside the linkage frame, and the welding torch is located above the linkage frame. By controlling the extension of a square electric telescopic rod, the square electric telescopic rod is inserted into the inside of a sleeve through a square slot. Then, the motor is started according to the height of the beam-column joint. The motor starts and drives the load-bearing plate to rise. At the same time, the rotation of the threaded rod drives the square electric telescopic rod to rotate through the interaction of the second bevel gear, the first bevel gear, and the sleeve. The rotation of the square electric telescopic rod achieves the effect of releasing the electric wire. After welding, the welding torch is inserted into the inside of the sleeve for protection. This solves the problem that it is not only very laborious but also dangerous for manual welding equipment to climb onto the beam and column for welding.

[0004] However, the horizontal insertion protection structure of the welding torch used in this patent has the problem that the connection between the welding torch tail end and the wire is prone to bending under gravity, and the excessive fatigue strength leads to the wire breaking at the connection, making the welding torch unusable. In addition, the synchronous wire feeding and take-up structure of this patent cannot stretch the wire separately after it is raised to a certain working position without affecting the internal wire recycling. Therefore, an automated welding processing equipment for steel nodes is needed to solve the above problems. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1-7 As shown, this is an automated welding equipment for steel nodes. The equipment includes a linkage frame 1, a wire 2, and a welding torch 10. The wire 2 is located inside the linkage frame 1, and the welding torch 10 is located above the linkage frame 1. A power supply 3, electrically connected to the wire 2, is installed at the bottom right side inside the linkage frame 1. A shock-absorbing pad is provided at the bottom left side inside the linkage frame 1, and a drive motor 4 is fixedly installed on the shock-absorbing pad. The output shaft of the drive motor 4 is connected to a lifting assembly 5. A load-bearing plate 8 is installed on the lifting assembly 5, and a placement mechanism 9 is provided on the load-bearing plate 8 to place the welding torch 10 and protect it. A transmission assembly 6 is provided at the top of the linkage frame 1 near the lifting assembly 5. The transmission assembly 6 is connected to the lifting assembly 5 to transmit motion. A wire winding and unwinding mechanism 7 is provided on the right side of the transmission assembly 6, in which the wire 2 is wound around the wire winding and unwinding mechanism 7. During the lifting and unwinding movement of the welding torch 10, the wire 2 is wound and unwound synchronously, further facilitating the use of the welding torch 10 at high positions.

[0032] Further such as Figure 1 and Figure 2 As shown, the lifting assembly 5 includes a lifting threaded rod 52. The bottom end of the lifting threaded rod 52 is unthreaded and extends through the top plate of the linkage frame 1 into the interior of the linkage frame 1. The lifting threaded rod 52 is fixedly connected to the output shaft of the drive motor 4 inside the linkage frame 1. A first bevel gear 51 is connected to the bottom end of the lifting threaded rod 52. The first bevel gear 51 cooperates with the transmission assembly 6 to transmit motion. The end of the lifting threaded rod 52 located outside the linkage frame 1 is threaded. The lifting threaded rod 52 is connected to a load-bearing plate 8. The load-bearing plate 8 is located near the lifting threaded rod. A connecting sleeve 81 is installed on the threaded rod 52, which is threadedly connected to the lifting threaded rod 52. A guide rod 53 is provided at the top of the linkage frame 1 away from the lifting threaded rod 52. The guide rod 53 is parallel to the lifting threaded rod 52. The end of the load-bearing plate 8 near the guide rod 53 is slidably connected to the guide rod 53. By starting the drive motor 4, the lifting threaded rod 52 is driven to rotate. The lifting threaded rod 52 drives the load-bearing plate 8 to rise and fall. The load-bearing plate 8 drives the placement mechanism 9 installed on its top to move, which facilitates the welding of the steel nodes at high positions.

[0033] Furthermore, to avoid the existing horizontally fixed welding torch 10, which causes the connection between the tail end of the welding torch 10 and the wire 2 to easily bend under gravity, resulting in excessive fatigue strength and breakage of the wire 2 at the connection point, rendering the welding torch 10 unusable, such as... Figure 1 and Figure 4 As shown, a placement mechanism 9 is provided for vertically placing the welding torch 10. This placement mechanism 9 includes a vertical base 91 fixedly installed on the top surface of the load-bearing plate 8. A gear seat 93 is connected to the top of the vertical base 91 near the lifting threaded rod 52. A protective cover 95 is installed on the gear seat 93. The structure of the gear seat 93 is as follows: Figure 5 As shown, (with) Figure 4 (Based on the direction) Sliding grooves 931 are symmetrically provided on both the inner and outer sides of the tooth seat 93. A tooth groove 932 is provided in the middle of the side of the tooth seat 93 near the protective cover 95. Furthermore, a moving rack 94 is symmetrically provided on the side of the tooth seat 93 near the protective cover 95 about the tooth groove 932. A moving rack 94 is also provided on the outer side inside the tooth groove 932.

[0034] Further such as Figure 4 As shown, a placement cavity 97 is provided on one side of the protective cover 95. Multiple heat dissipation holes 98 are provided on the top of the placement cavity 97, connecting the outside to the inside of the placement cavity 97. Further, a heat dissipation groove 99 is provided on the side of the placement cavity 97 near the gear seat 93. A rotating hole is provided in the heat dissipation groove 99, and a rotating rod is rotatably connected to the rotating hole. A cooling fan 911 is installed on the rotating rod in the heat dissipation groove 99. The other end of the rotating rod is as shown... Figure 5The protective cover 95 is connected to a rotating gear 912, which meshes with a moving rack 94 inside a tooth groove 932. A moving groove 96 is provided at the tooth base 93 position of the protective cover 95. The moving groove 96 is adapted to the tooth base 93, and symmetrical sliding bars are arranged on both sides of the moving groove 96. The two sliding bars are slidably connected to the corresponding sliding grooves 931. Further, symmetrical through grooves are provided on both sides of the bottom of the protective cover 95 near the tooth base 93. A connecting rod is connected between the two through grooves, and connecting gears 910 are installed at both ends of the connecting rod. The two connecting gears 910 mesh with the corresponding moving racks 94, enabling the protective cover 95 to move steadily on the tooth base 93. During this movement, the rotating gear 912 rotates, which in turn drives the cooling fan 911 to rotate, blowing air into the placement cavity 97 to accelerate the heat dissipation of the welding torch head 101. A handle is provided on the top of the protective cover 95 to facilitate repeated movement and accelerate heat dissipation, thus improving the heat dissipation effect.

[0035] In this invention, the connecting gear 910 and the rotating gear 912 have the same number of teeth.

[0036] To ensure that the wire 2 can be released and tightened synchronously when the load-bearing plate 8 rises and falls, and that the wire 2 can be stretched independently when it rises to the working position, such as... Figure 2 and Figure 3 As shown, the present invention is provided with a transmission component 6 and a take-up and release mechanism 7. The driving force of the drive motor 4 is transmitted to the take-up and release mechanism 7 through the cooperation of the transmission component 6 and the take-up and release mechanism 7, so that the wire 2 can be synchronously released and tightened as the load-bearing plate 8 rises and falls. The transmission component 6 includes a connecting frame 62 fixedly connected to the top surface of the linkage frame 1. A transmission base 63 is rotatably connected to the connecting frame 62. One end of the transmission base 63 is connected to a second bevel gear 61, and the second bevel gear 61 meshes with a first bevel gear 51. The rotation of the first bevel gear 51 can drive the transmission base 63 to rotate. The other end of the transmission base 63 is provided with a square mounting groove. The mounting groove cooperates with the take-up and release mechanism 7 to realize the transmission and disconnection of power.

[0037] Further such as Figure 2 and Figure 3As shown, the above-mentioned take-up and unwind mechanism 7 includes a first fixed frame 71 and a second fixed frame 72 connected to both sides of the bottom surface of the linkage frame 1. The first fixed frame 71 is located close to the drive motor 4, and the power supply 3 is located between the first fixed frame 71 and the second fixed frame 72. A drive shaft 79 is rotatably connected between the first fixed frame 71 and the second fixed frame 72. An inner rotating roller 73 is sleeved on the outside of the drive shaft 79 and located between the first fixed frame 71 and the second fixed frame 72. An outer rotating roller 76 is sleeved on the outside of the inner rotating roller 73, and both ends of the outer rotating roller 76 are fitted into mounting grooves 74 symmetrically opened on both sides of the inner rotating roller 73. A coil spring 75 is installed inside the mounting groove 74. One end of the coil spring 75 is connected to the mounting groove 74, and the other end is connected to the outer rotating roller 76 to realize the position recovery of the inner rotating roller 73 after rotation. The inner rotating roller 73 has a central opening. A connecting groove 77 is adapted to the drive shaft 79. A mounting groove 4 is provided in the middle of the connecting groove 77, and a connecting key 78 is adapted to be installed in the mounting groove 4. A keyway 710 is also provided in the middle of the drive shaft 79, and the connecting key 78 is fitted in the keyway 710. In order to enable the drive shaft 79 to move back and forth, the length of the keyway 710 is much greater than the length of the connecting key 78, so as to realize the position change of the drive shaft 79. Furthermore, a connecting groove 711 is also provided in the middle of the outer roller 76. The connecting groove 711 is adapted to the shaft section of the inner roller 73. With the setting of the disc spring 75, it can apply force to pull the outer roller 76 to rotate within a small range. After release, the outer roller 76 returns to its position. A wire 2 is wound around the outside of the outer roller 76. A connector 25 is provided at the end of the wire 2 near the power supply 3. The wire 2 is connected to the power supply 3 through the connector 25.

[0038] Furthermore, to allow the drive shaft 79 to rotate or remain stationary, a rectangular mounting groove is provided on the outer side of the first fixing frame 71, and a circular mounting groove is provided on the outer side of the second fixing frame 72. A rectangular mounting bracket 714 is further provided at the left end of the drive shaft 79, and a circular mounting bracket 713 is provided at the right end. An electric telescopic rod 712 is connected to the right end face of the drive shaft 79. This electric telescopic rod 712 is rotatably connected to the right side wall inside the linkage frame 1. Activating the electric telescopic rod 712 causes the drive shaft 79 to move left and right. A square connecting shaft 715 is connected to the left end of the drive shaft 79, and a pointed corner 716 is provided at the front end of the square connecting shaft 715. Activating the electric telescopic rod 712 extends and pushes the drive shaft 79 to the left, causing the circular mounting bracket 713 to engage in the circular mounting groove, and the rectangular mounting bracket 714 to disengage from the rectangular mounting groove (e.g., ...). Figure 3 As shown), the extended square connecting shaft 715 is inserted into the square assembly slot of the conductive base 63. The drive motor 4 drives the transmission shaft 79 to rotate, and the transmission shaft 79 drives the inner rotating roller 73 and the outer rotating roller 76 to rotate, thereby releasing or tightening the wire 2.

[0039] In order to allow wire 2 to still be stretched to a small extent when rising to the working position, such as Figure 1 and Figure 2 As shown, a first sliding sleeve 21 is provided at the top of the linkage frame 1, and a second sliding sleeve 22 is provided at the corresponding position of the load-bearing plate 8. Both the first sliding sleeve 21 and the second sliding sleeve 22 are slidably sleeved on the outside of the wire 2, and multiple limiting protrusions 23 are provided at the upper end of the wire 2 for limiting after stretching to prevent the restoring force of the coil spring 75 from retracting the wire 2. A wire clamping plate 915 is provided in the middle of the vertical base 91. A circular groove 917 is opened in the middle of the wire clamping plate 915, and an inclined groove 916 is opened in the oblique direction of the circular groove 917. The direction of the inclined groove 916 is as follows: Figure 7 As shown, the side of the clamping plate 915 near the inclined groove 916 is inclined to the upper left and is the connection surface for connecting with the vertical base 91. When the welding gun 10 cannot reach the steel node to be welded, the wire 2 is pulled to clamp the corresponding limiting protrusion 23 onto the clamping plate 915, which facilitates welding. At the same time, in order to make the stretching more convenient and avoid slippage, a pull wire grip 24 is provided on the wire 2 to facilitate force stretching, making the equipment suitable for different working scenarios.

[0040] Furthermore, to facilitate the vertical placement of the welding torch 10, a mounting groove 92 is provided on one side of the vertical base 91. The welding torch 10 includes a welding torch head 101 and a welding torch handle 102. The welding torch handle 102 is adapted to the mounting groove 92, and as such... Figure 6 As shown, the vertical base 91 is also provided with a mounting groove 913. One end of the mounting groove 913 is connected to the insertion slot on the vertical base 91, and the other end is connected to the through slot, which extends to the outside. A positioning rod 914 is provided in the mounting groove 913. The positioning rod 914 is provided with a boss in the mounting groove 913. A return spring is provided between the boss and the mounting groove 913. Pulling the positioning rod 914 can pull the front end of the positioning rod 914 out of the mounting groove 92, which is convenient for the welding gun placement handle 102 to be moved out. A limiting plate 103 is also provided on the welding gun placement handle 102 for placement limitation. The front end of the positioning rod 914 is provided with an inclined surface, which is convenient for the welding gun placement handle 102 to be directly inserted from the outside.

[0041] When this invention is in operation, the linkage frame 1 is first transported to the corresponding position. After disconnecting the connector 25, the electric telescopic rod 712 is started, and the left end of the transmission shaft 79 is connected to the transmission base 63. Then, the drive motor 4 is started, which drives the lifting threaded rod 52 and the first bevel gear 51 to rotate. The lifting threaded rod 52 drives the load-bearing plate 8 to rise. The load-bearing plate 8 drives the placement mechanism 9 to move upward. At the same time, the first bevel gear 51 drives the second bevel gear 61 to rotate. The second bevel gear 61 drives the transmission base 63 to rotate. The transmission base 63 drives the transmission shaft 79 to rotate. The transmission shaft 79 drives the inner rotating roller 73 and the outer rotating roller 76 to rotate, and the wire 2 is released synchronously, so that the rising welding torch 10 can pull the wire 2 to rise.

[0042] When the work position requires welding of steel nodes at different locations using the extended wire 2, the electric telescopic rod 712 is activated to retract, disconnecting the drive shaft 79 from the transmission base 63. Then, the rectangular bracket 714 is engaged in the rectangular mounting slot. The wire 2 is pulled by holding the pull wire grip 24, and the corresponding limiting protrusion 23 is engaged on the wire clamping plate 915 for use. After use, when the wire 2 needs to be retracted, the pull wire grip 24 is pulled to remove the wire 2 from the wire clamping plate 915. The pulled wire 2 is then retracted by the coil spring 75 to prevent the pulled wire 2 from not being fully retracted into the linkage frame 1 during synchronous tightening, which would cause the wire 2 to become messy and affect the next use.

[0043] When finishing work and tidying up the welding torch 10, push the welding torch holder 102 into the mounting slot 92. The welding torch holder 102 presses against the positioning rod 914 until it is inserted into the slot opened on the welding torch holder 102, where the limiting plate 103 limits the position. Then, press down the protective cover 95 (which was in the top position before starting). The protective cover 95 moves down, driving the rotating gear 912 to rotate. The rotating gear 912 drives the cooling fan 911 to rotate, blowing air onto the welding torch head 101 after work to dissipate heat. At the same time, the placement cavity 97 of the protective cover 95 covers the welding torch head 101 for protection, preventing workers from accidentally touching the welding torch head 101 and causing injury.
