[0038] refer to Figure 1-Figure 13 As shown, in an embodiment of the present invention, a T-beam web frame monolithic welding device is provided, which is used to weld the upper and lower overlapping horseshoe tendons 41 and long stirrups 42 together to form a skeleton monolithic piece of the T-beam web reinforcement skeleton (hereinafter referred to as the skeleton monolithic piece 40). The T-beam web frame monolithic welding device includes a pedestal 10 and a welding mechanism 20, the pedestal 10 includes a plurality of positioning slot seats 13, and the positioning slot seats 13 are provided with a plurality of positioning slots with notches facing upwards, which are used to position the horseshoe tendons 41 and the long stirrups 42, and the welding mechanism 20 is arranged on the pedestal 10, and is used to weld and fix the horseshoe tendons 41 and the long stirrups 42.

[0039] refer to Fig.14 As shown, the horseshoe tendon 41 and the long stirrup 42 constituting the skeleton single piece 40 include a first overlap point located at the first end of the long stirrup 42 along the length direction, and a second overlap point and a third overlap point located at opposite sides of the long stirrup 42 along the width direction and symmetrically arranged. In order to stably connect the horseshoe tendon 41 and the long stirrup 42, it is necessary to weld and fix at the first overlap point, the second overlap point, and the third overlap point, that is, the first overlap point is the first welding point A, the second overlap point is the second welding point B, and the third overlap point is the third welding point C. On this basis, the welding mechanism 20 includes a first welding mechanism 20a and a second welding mechanism 20b, wherein the first welding mechanism 20a includes a first welding assembly for welding and fixing the first welding point A, and the second welding mechanism 20b includes two groups of second welding assemblies symmetrically arranged along the second direction, respectively used for welding and fixing the second welding point B and the third welding point C. In order to avoid the horseshoe tendon 41 and the long stirrup 42 when they are placed in the positioning groove seat 13, the first welding assembly in the first welding mechanism 20a is slidably arranged on the platform 10 along the first direction, and the first welding mechanism 20a includes a first driving member 25 that drives the first welding assembly to move along the first direction. The two groups of second welding assemblies in the second welding mechanism 20b are slidably arranged on the platform 10 along the second direction, and the second welding mechanism 20b includes a second driving member 26 that drives the two groups of second welding assemblies to move toward or away from each other along the second direction. The first direction is the length direction of the long stirrup 42 ( Figure 1 The second direction is the width direction of the long stirrup 42 ( Figure 1 The first direction and the second direction are perpendicular to each other.

[0040] Continue to refer Fig.14 As shown, the long stirrups 42 constituting the skeleton monolithic sheet 40 are formed by bending steel bars, and the long stirrups 42 include a connecting section 421, an extension section 422 and a bending section 423, wherein the connecting section 421 is U-shaped, and the two extension sections 422 are respectively connected to the two ends of the connecting section 421, and the two bending sections 423 are formed by bending the two extension sections 422 toward each other. In order to maintain the stability of the shape of the long stirrups 42, the two bending sections 423 need to be connected and fixed, therefore, the skeleton monolithic sheet 40 also includes a fourth welding point D located at one end of the long stirrups 42 away from the first welding point A. Based on this, the welding mechanism 20 also includes a third welding mechanism 20c, and the third welding mechanism 20c includes a third welding assembly slidably disposed on the pedestal 10 along the first direction, and the third welding mechanism 20c also includes a third driving member 27 for driving the third welding assembly to move along the first direction, and the second welding mechanism 20b is located between the first welding mechanism 20a and the third welding mechanism 20c.

[0041] Since the two bent sections 423 of the long stirrup 42 are not fixed, affected by the elasticity of the long stirrup 42 itself, the initial distance between the two extension sections 422 of the long stirrup 42 placed on the positioning slot seat 13 along the second direction is greater than the preset distance. On this basis, the T-beam web frame single-piece welding device also includes a clamping mechanism 30 located between the second welding mechanism 20b and the third welding mechanism 20c. The clamping mechanism 30 includes two clamping assemblies 31 arranged to slide at intervals along the second direction and a fourth driving member 32 for driving the two clamping assemblies 31 to move toward or away from each other along the second direction. The two clamping assemblies 31 are respectively used to clamp the two extension sections 422 and drive the two extension sections 422 to move along the second direction, so that the two extension sections 422 are close to each other to a preset distance.

[0042] The above-mentioned T-beam web frame single-piece welding device uses a clamping mechanism 30 to cooperate with the positioning groove seat 13 on the pedestal 10 to position the horseshoe tendon 41 and the long stirrup 42, and at the same time uses a welding mechanism 20 movably arranged on the pedestal 10 to weld the welding points of the horseshoe tendon 41 and the long stirrup 42, thereby realizing automatic welding of the single-piece frame 40 with high forming accuracy and production efficiency.

[0043] refer to Figure 2As shown, the positioning slot seats 13 are grouped in pairs to form a positioning slot seat group, and the pedestal 10 includes three groups of positioning slot seat groups, two of which are used to support and position the horseshoe tendon 41, and one group is used to support and position the long stirrup 42. Specifically, for the convenience of description, the two groups of positioning slot seat groups used to support and position the horseshoe tendon 41 are respectively defined as the first positioning slot seat group and the second positioning slot seat group, and the positioning slot seat group used to support and position the long stirrup 42 is defined as the third positioning slot seat group. The positioning slots provided on the positioning slot seats 13 in the first positioning slot seat group and the third positioning slot seat group all penetrate the positioning slot seats 13 along the first direction, and the positioning slots provided on the two positioning slot seats 13 in the second positioning slot seat group penetrate the positioning slot seats 13 along the second direction.

[0044] More specifically, in order to reduce the difficulty of the horseshoe tendon 41 and the long stirrup 42 entering the positioning slot, the notch of the positioning slot is configured to be a trumpet shape that gradually converges from top to bottom.

[0045] refer to Figure 1 As shown, the pedestal 10 includes a frame 11 and a panel 12, the panel 12 is fixed to the outer surface of the frame 11, and the panel 12 is provided with an escape opening for the welding mechanism 20 and the clamping mechanism 30 to pass through, the positioning groove seat 13 is embedded in the top surface of the panel 12, and the bottom of the positioning groove on the positioning groove seat 13 is flush with the top surface of the panel 12, when the horseshoe tendon 41 and the long stirrup 42 are placed in the positioning groove seat 13, the pedestal 10 can cooperate with the positioning groove seat 13 to support the horseshoe tendon 41 and the long stirrup 42, thereby reducing the possibility of deformation of the horseshoe tendon 41 and the long stirrup 42 due to gravity.

[0046] refer to Figure 5 and Figure 6 As shown, the clamping assembly 31 includes a mounting base plate 313, two clamping plates 311 spaced apart along the second direction, and a fifth driving member 312. The two clamping plates 311 are both arranged on the mounting base plate 313, at least one clamping plate 311 is connected to the fifth driving member 312, and the fifth driving member 312 is configured to drive the clamping plate 311 to reciprocate along the second direction to clamp or loosen the long stirrup 42.

[0047] Exemplarily, the fifth driving member 312 adopts a cylinder, and in order to use the same fourth driving member 32 to make the two clamping assemblies 31 move toward or away from each other, the clamping mechanism 30 also includes a flexible transmission structure, and the fourth driving member 32 adopts a motor, and the motor is connected to the two clamping assemblies 31 through the flexible transmission structure. Specifically, the flexible transmission structure includes a sprocket and a chain, and the chain is wound between two sprockets arranged at intervals along the second direction, one of the sprockets is connected to the fourth driving member 32, and the two clamping assemblies 31 are respectively arranged on the upper and lower layers of the chain through a clamping plate, so as to achieve movement toward or away from each other under the drive of the motor. In order to enable the clamping plate 311 to protrude from the panel 12, the clamping mechanism 30 also includes a support frame 33, and the clamping assembly 31 is slidably arranged on the support frame 33 along the second direction. The support frame 33 is also provided with a positioning guide rail for guiding the moving direction of the clamping assembly 31, and the clamping assembly 31 is slidably connected to the support frame 33 through the positioning guide rail.

[0048] refer to Figure 7-Figure 13 As shown, the first welding assembly, the second welding assembly and the third welding assembly all include an upper electrode 22, a lower electrode 23 and a sixth driving member 24. The first welding assembly, the second welding assembly and the third welding assembly are each slidably disposed on the pedestal 10 through a sliding base plate 21. The upper electrode 22 and the lower electrode 23 are spaced apart from each other on the sliding base plate 21. The sixth driving member 24 is connected to the lower electrode 23 to drive the lower electrode 23 to rise and fall, so that the lower electrode 23 cooperates with the upper electrode 22 to clamp the steel bars and weld the steel bars.

[0049] Exemplarily, the first driving member 25 and the sixth driving member 24 are both cylinders, the third driving member 27 is a motor, a rack is provided on the pedestal 10, and a gear meshing with the rack is provided on the motor as the third driving member 27. When the motor rotates, the gear meshing with the rack drives the third welding assembly to move in the first direction. The second driving member 26 also uses a motor, and the motor cooperates with the flexible transmission structure to drive the two second welding assemblies. It should be emphasized that in order to realize the synchronous movement of the two second welding assemblies toward and away from each other along the second direction, the two second welding assemblies are respectively arranged on the upper and lower layers of the flexible member (such as a chain) in the flexible transmission structure.

[0051] In order to adapt to the welding of single-piece frames of different lengths, the second welding mechanism 20b further includes an eighth driving member 29, which is configured to drive the second welding assembly to move along the first direction. Specifically, the second welding mechanism 20b further includes a translation chassis, which is slidably arranged on the pedestal 10 along the first direction, and a sliding base plate 21 of the second welding mechanism 20b is arranged on the translation chassis.

[0052] Exemplarily, the eighth driving member 29 also adopts a motor, which cooperates with the gear rack transmission structure to drive the translation chassis to move along the first direction.

[0053] When the T-beam web frame single-piece welding device in this embodiment is used to weld the frame single piece 40, the horseshoe tendon 41 and the long stirrup 42 are restricted on the positioning groove seat 13, the first welding mechanism 20a moves along the first direction to the preset first welding position, the second welding mechanism 20b moves along the first direction as a whole, and the two second welding assemblies move along the second direction to the second welding position and the third welding position, the third welding mechanism 20c moves along the first direction to the preset fourth welding position, the clamping assemblies 31 in the clamping mechanism 30 move along the second direction to the preset first clamping position and the second clamping position, and clamp the two clamping sections of the long stirrup 42, then the first welding assembly, the second welding assembly, and the third welding assembly descend, so that the upper electrode 22 abuts against the steel bar, the lower electrode 23 rises and clamps the steel bar together with the upper electrode 22, and the welding operation begins. After the welding is completed, each welding mechanism 20 and the clamping mechanism 30 return to the initial position to complete the welding operation.
