[0017] like Figure 1 As shown, the present invention provides a steel bar welding device for construction engineering, including a frame 1, the frame 1 includes a bottom plate and a top plate, a group of support rods are connected between the top plate and the bottom plate, and a driving member 2 is connected to the top of the frame 1. In this embodiment, the driving member 2 is a cylinder, and a through hole is provided on the top plate. The piston rod of the cylinder passes through the through hole, and a lifting plate 3 is connected to the lower side of the driving rod of the driving member 2, and a welding gun 4 is connected to the lower side of the lifting plate 3. The lifting plate 3 is driven to rise and fall by the cylinder, thereby driving the welding gun 4 to rise and fall.

[0018] like Figure 2 As shown, two supporting mechanisms for placing steel bars are connected at the bottom of the frame 1, the welding gun 4 is provided above the middle of the two supporting mechanisms, the supporting mechanism includes two relatively arranged supporting members 5, the supporting member 5 includes a fixed box 6, a raising plate 6.2 is provided on the lower side of each fixed box 6, a receiving trolley 6.3 is provided between every two corresponding raising plates 6.2, the carriage of the receiving trolley 6.3 is a U-shaped structure, and the steel bars dropped from the supporting member 5 are received by the receiving trolley 6.3.

[0019] like Figure 3 As shown, through holes are provided on both side walls of each fixed box 6, the two through holes are coaxially arranged, a fixed rod 7 passes through the two through holes, a sliding plate 7.1 is connected to the fixed rod 7, the sliding plate 7.1 slides in the corresponding fixed box 6, a first spring 6.1 is connected between the sliding plate 7.1 and the inner side of the corresponding fixed box 6, and the fixed rod 7 is reset by the first spring 6.1.

[0020] A support roller mechanism 8 is connected to the opposite ends of the two fixed rods 7. The support roller mechanism 8 includes a U-shaped bracket 8.1, a support roller 8.2 is rotatably connected in the U-shaped bracket 8.1, and a drive motor 8.3 is connected to one side of the U-shaped bracket 8.1. The drive motor 8.3 is used to drive the support roller 8.2 to rotate. The steel bars are supported by the two support rollers 8.2, and the support rollers 8.2 are driven to rotate by the drive motor 8.3. The support rollers 8.2 drive the steel bars to rotate, so that the steel bars can also rotate during welding, thereby improving the welding efficiency.

[0021] Two pressing roller assemblies 9 are connected to the lifting plate 3. The pressing roller assembly 9 includes a bracket. The two pressing rollers are rotatably connected in the bracket. The two pressing rollers can not only press the steel bars, but also will not hinder the rotation of the steel bars.

[0022] A set of elastic retractable members 10 are also connected between the lifting plate 3 and the pressing roller assembly 9. Figure 4 As shown, the elastic telescopic member 10 includes a sleeve 101, a sliding rod 102 is inserted into the sleeve 101, the clamping roller assembly 9 is connected to the lower side of the sliding rod 102, and a second spring 103 is connected between the sliding rod 102 and the corresponding inner side of the sleeve 101. When the driving member 2 drives the lifting plate 3 to move downward, the lifting plate 3 drives the clamping roller assembly 9 and the welding gun 4 to move downward, and the clamping roller assembly 9 is first pressed on the steel bar. When the welding gun 4 then moves downward, the sliding rod 102 retracts into the sleeve 101, which will not hinder the downward movement of the welding gun 4, and the elastic force of the second spring 103 can ensure that the clamping roller can always be firmly pressed on the steel bar.

[0023] Two transmission mechanisms are also connected to the lifting plate 3. When the lifting plate 3 moves downward, each transmission mechanism drives the corresponding two fixing rods 7 to move toward the middle.

[0024] The transmission mechanism includes two transmission members, which include a first push block 11 and a second push block 12 that are arranged in a coordinated manner. The first push block 11 is connected to the corresponding fixing rod 7, and the second push block 12 is connected to the lower side of the lifting plate 3 through a connecting rod 13.

[0025] An inclined surface is provided on the upper side of the first pushing block 11, and an inclined surface is provided on the lower side of the second pushing block 12. When the second pushing block 12 moves downward, the inclined surface of the second pushing block 12 will push the inclined surface of the first pushing block 11 downward, so that the first pushing block 11 drives the fixing rod 7 to move toward the middle, thereby making the two supporting rollers 8.2 move toward the middle, so that the two supporting rollers 8.2 can support the steel bars, and the second pushing block 12 can then move downward along the side wall of the first pushing block 11. The height of the first pushing block 11 is sufficient. Before the lifting plate 3 drives the welding gun 4 to contact the steel bars, the second pushing block 12 can move along the side wall of the first pushing block 11 all the time. When the second pushing block 12 moves upward and disengages from the first pushing block 11, the first pushing block 11 is reset under the elastic force of the first spring 6.1, so that the two supporting rollers 8.2 are separated, so that the welded steel bars fall downward from between the two supporting rollers 8.2.

[0026] Before using the device, the driving member 2 is started to drive the second pushing block 12 to press the first pushing block 11 downward, so that the two supporting rollers 8.2 move toward the middle, so that the two supporting rollers 8.2 can support the steel bar. When in use, the two sections of steel bars are placed on the corresponding two supporting rollers 8.2 respectively, and then the driving member 2 is started to drive the pressing roller assembly 9 to move downward to press the steel bar. After the steel bar is pressed, the lifting plate 3 continues to move downward to enable the welding gun 4 to weld the steel bar. When the welding gun 4 is welding the steel bar, the driving motor 8.3 is started to drive the supporting roller 8.2 to rotate, and the supporting roller 8.2 drives the steel bar to rotate, so that the welding gun When welding the steel bar, the steel bar can be rotated to improve the welding efficiency. After the welding is completed, the driving member 2 is started to drive the welding gun 4, the pressing roller assembly 9 and the second pushing block 12 to move upward. When the second pushing block 12 moves upward and separates from the first pushing block 11, the first pushing block 11 is reset under the elastic force of the first spring 6.1, thereby driving the two supporting rollers 8.2 to move to both sides, so that the welded steel bar falls downward from between the two supporting rollers 8.2 and falls into the receiving trolley 6.3, thereby quickly completing the unloading, which not only reduces the labor intensity of the employees but also improves the unloading efficiency.
