[0037] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0038] like Figure 1-5As shown, a T-beam web longitudinal reinforcement installation welding device, it should be noted that in the following embodiments, the first direction is the direction facing the T-beam web along the horizontal direction, and the second direction is the extension direction of the T-beam longitudinal reinforcement. The welding device includes a main frame 1, a lifting rod 7, a stirrup combing mechanism 8 and a longitudinal reinforcement combing mechanism 9. The main frame 1 is a portal frame formed by welding square steel or steel sections and corresponding to the T-beam frame 6. The shape of the T-beam frame 6 is adapted to the shape of the T-beam steel bar. The T-beam frame 6 is provided with a placement groove corresponding to the T-beam stirrups, so that the T-beam stirrups are placed according to the preset spacing and direction. The two sides of the main frame 1 corresponding to the T-beam frame 6 are lifting spaces. A plurality of lifting platforms 2 are longitudinally slidably mounted on both sides of the main frame 1. The lifting platforms 2 are used for installing the welding device, the stirrup combing mechanism 8 and the longitudinal reinforcement combing mechanism 9, thereby driving the stirrup combing mechanism 8 and the longitudinal reinforcement combing mechanism 9 to move longitudinally, so as to adapt to the longitudinal reinforcements spaced apart in the longitudinal direction, and the stirrups can be combed and positioned as the stirrup combing mechanism 8 rises.

[0039] A plurality of lifting rods 7 are linearly arranged on the top of the main frame 1. The lifting rods 7 can be any one of an air cylinder, an oil cylinder, and a ball screw. The lifting rods 7 can be extended and retracted in the longitudinal direction to drive the lifting platform 2 to move in the longitudinal direction. The lifting platform 2 is provided with through holes corresponding to the lifting rods 7. The lifting rods 7 pass through the through holes in sequence in the longitudinal direction. After the plurality of lifting rods 7 pass through the through holes in the longitudinal direction, they are connected one by one with the corresponding plurality of lifting platforms 2 to independently drive the lifting platforms 2. Specifically, taking the four lifting platforms 2 set in the present application as an example, four lifting rods 7 are correspondingly set, among which the first lifting rod 7 passes through the main frame 1 and is connected to the first lifting rod 7 from top to bottom. The second lifting rod 7 passes through the first lifting platform 2 from top to bottom and is connected to the second lifting platform 2. The third lifting rod 7 passes through the first and second lifting platforms 2 from top to bottom and is connected to the third lifting platform 2. The fourth lifting rod 7 passes through the first, second and third lifting platforms 2 from top to bottom and is connected to the fourth lifting platform 2. The diameter of the through hole is larger than the diameter of the lifting rod 7. The length or telescopic stroke of the lifting rod 7 is adjusted according to the actual position of the corresponding lifting platform 2. A connecting flange is provided at the driving end of the lifting rod 7, which is fixed to the corresponding lifting platform 2 through the connecting flange. The lifting platform 2 is a square plate. In order to avoid mutual interference, the stirrup combing mechanism 8 and the longitudinal reinforcement combing mechanism 9 are respectively arranged on the opposite sides of the lifting platform 2, specifically on the upper side or the lower side. The stirrup combing mechanism 8 is arranged in the middle of one side of the lifting platform 2. Preferably, the stirrup combing mechanism 8 is located at the midline of the upper side of the lifting platform 2. The stirrup combing mechanism 8 is slidably assembled with the lifting platform 2 along a first direction. The first direction is the direction of the web of the T-beam 17 along the horizontal direction on both sides of the main frame 1. The stirrup combing mechanism 8 can extend or retract into the lifting platform 2. After the stirrup combing mechanism 8 extends out of the lifting platform 2, it clamps the T-beam stirrups, thereby combing the T-beam stirrups.

[0040] The longitudinal reinforcement combing mechanism 9 is arranged in the middle of the other side of the lifting platform 2 through the base 16. The base 16 is slidably assembled along a first direction and a second direction perpendicular to the first direction, wherein the second direction is the direction along which the longitudinal reinforcement of the T-beam extends, thereby meeting the demand for combing the longitudinal reinforcement of the T-beam. A welding device slidably assembled along the first direction is provided in the middle of the base 16, and the welding device is slidably assembled along the first direction. Two longitudinal reinforcement combing mechanisms 9 are respectively located on both sides of the welding device, thereby the longitudinal reinforcement of the T-beam on both sides of the welding device can be combed along the second direction. The longitudinal reinforcement of the T-beam is limited by the longitudinal reinforcement combing mechanism 9 to ensure the position accuracy of the longitudinal reinforcement of the T-beam during welding.

[0041] In actual use, the stirrup combing mechanism 8 extends out to clamp the T-beam stirrups, and the longitudinal reinforcement combing mechanism 9 is manually or mechanically loaded into the T-beam longitudinal reinforcement.

[0043] The welding device is resistance welding. The two welding heads first move in the first direction and extend into the inner side of the stirrups. Then the cylinder moves in the second direction to bring the stirrups into the welding heads. Then the welding heads move backward in the first direction to pull the stirrups back, close the stirrups and the longitudinal bars, and then resistance welding. The principle of this welding is to melt and weld the intersection of the stirrups and the longitudinal bars through electricity. It is not considered double-sided welding.
