Description

Technical Field

[0001] This invention relates to the field of communication tower manufacturing, and more particularly to a welding equipment for the production of steel structures for communication towers. Background Technology

[0002] A communication tower is a structure used to support wireless communication antennas. It is mainly composed of steel structures connected by welding and bolts. It has a low wind pressure resistance, high cross-sectional bending stiffness, simple structure, clear force transmission, and can make full use of the load-bearing performance of materials.

[0003] The poles of a communication tower are typically constructed from single equilateral angle steel bars. During production, to enhance the strength of the equilateral angle steel, improve the overall structural stability, and facilitate connections with other steel structures, several reinforcing rings are usually welded to its surface. The specific welding method involves manually welding multiple ribs in a circular array onto the equilateral angle steel. Then, two curved steel sections are spliced ​​onto the welded ribs and welded together to form a complete ring-shaped component. However, this process requires manual placement, alignment, and welding of the ribs, resulting in low overall welding efficiency. Furthermore, the ribs are prone to skewing during welding, affecting the weld strength of the subsequent reinforcing rings. Welding the curved steel sections also requires multiple people to work together to splice and fix them, consuming significant manpower and hindering the overall production efficiency of the communication tower's steel structure.

[0004] In summary, this application proposes a welding equipment for the production of communication tower steel structures, which improves the aforementioned technical problems. Summary of the Invention

[0005] To overcome the shortcomings of the low overall welding efficiency caused by the need for manual placement, calibration, and welding of ribs during the welding process, and the tendency for ribs to become skewed during welding, which affects the weld strength of the subsequent reinforcing rings, this invention provides a welding equipment for the production of communication tower steel structures.

[0006] Technical Solution: A welding equipment for producing steel structures for communication towers includes a connecting frame and two drive motors mounted on the connecting frame. Two arc-shaped plates are rotatably connected to the connecting frame, and the outputs of each drive motor are fixedly connected to one arc-shaped plate. Each arc-shaped plate is provided with a slide rail, and the equipment also includes several electric slide tables slidably connected to the slide rails of the arc-shaped plates. Each electric slide table is provided with a slide rail, and a placement plate is slidably connected to the slide rail via an electric slider. An electric clamping plate is installed on each side of the placement plate. An electric push rod is fixedly connected to the connecting frame. A connecting frame 2 is fixedly connected to the telescopic part of the electric push rod, and the connecting frame 2 is slidably connected to the connecting frame 1 via a slide rod. Two drive motors are fixedly connected to the connecting frame 2. Two arc-shaped plates are rotatably connected to the connecting frame 2, and the arc-shaped plates are fixedly connected to the output shafts of the drive motors. Each arc-shaped plate is provided with a slide rail, and an electric slide table 2 is slidably connected to the slide rail. A slide rail is provided on the surface of the electric slide table 2, and two fixed plates are slidably connected to the slide rail via an electric slider.

[0007] Optionally, the mounting plate has a clearance groove.

[0008] Optionally, the surface of the fixing plate is rough.

[0009] Optionally, the placement plate is equipped with an electromagnet.

[0010] Optionally, the clamping part of the electric clamping plate is trapezoidal, with the end closer to the placement plate being the narrow end and the end farther from the placement plate being the wide end.

[0011] Optionally, it also includes several electric slide tables three slidably connected to the slide rail of the arc plate two; each electric slide table three has a slide groove on its surface, and a linear electric slider one and a linear electric slider two are slidably connected to the slide groove; each linear electric slider one is rotatably connected to a fixed roller one; the linear electric slider two is fixedly connected to an electric motor; and the output part of the electric motor is fixedly connected to a fixed roller two.

[0012] Optionally, the surface of the fixed roller is detachably connected with a polishing layer.

[0013] Optionally, it also includes mounting blocks, electric push rod II, and electric rollers; several mounting blocks arranged in a circular array are fixedly connected to the left side of arc plate I and the right side of arc plate II; each mounting block is fixedly connected to an electric push rod II; each telescopic part of electric push rod II is equipped with an electric roller.

[0014] Optionally, the electric roller is equipped with a locking mechanism.

[0015] Optionally, it also includes a suction tube connected to an external suction mechanism; each of the three motorized slides is fixedly connected to a suction tube.

[0016] The beneficial effects are: by placing the ribs on the placement plate and then rotating the placement plate along the arc plate, the ribs are automatically positioned and automatically aligned with the equilateral angle steel. Compared with manual placement and alignment, this can effectively improve the overall welding efficiency. In addition, the electric clamping plate always clamps and fixes the ribs, preventing them from tilting due to manual touch or interference during the welding process, thus ensuring the overall welding quality.

[0017] By moving the fixed rollers one and two along the electric slide table in three directions along the equilateral angle steel, the curved steel is driven to move towards the equilateral angle steel, so that the curved steel is fully in contact with the rib plate, and the two curved steel pieces are tightly in contact. Compared with the existing method of multiple people working together to splice, this method can effectively improve the overall splicing efficiency, and thus improve the overall production efficiency of welding communication tower steel structures.

[0018] By controlling the retraction of the electric push rod and the rotation of the electric rollers on the arc plate, the placement plate is moved laterally along the equilateral angle steel, applying a lateral thrust to the welded rib plate, thereby detecting the welding quality between the rib plate and the equilateral angle steel; by controlling the movement of the fixed rollers one and two away from the equilateral angle steel, a tensile test is performed on the welded part between the rib plate and the arc steel to detect the welding quality of that part, thereby ensuring the overall welding quality of the communication tower steel structure.

[0019] The entire equipment is automatically moved on the equilateral angle steel by electric rollers, thereby improving the overall welding efficiency. Attached Figure Description

Detailed Implementation

[0028] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0029] Example 1: A welding equipment for the production of communication tower steel structures, referring to... Figures 1-7 As shown, it includes a connecting frame 1, a drive motor 2, and an arc plate 3; the connecting frame 1 is rotatably connected to two arc plates 3; the connecting frame 1 is fixedly connected to two drive motors 2, and the output of each of the two drive motors 2 is fixedly connected to one arc plate 3.

[0030] Each arc-shaped plate 3 is equipped with a slide rail and also includes an electric slide table 4, a placement plate 5, an electric clamping plate 6, an electric push rod 7, a connecting frame 8, a drive motor 9, an arc-shaped plate 10, an electric slide table 11, and a fixing plate 12. Several electric slide tables 4 are slidably connected to the slide rails on the arc-shaped plate 3. Each electric slide table 4 is equipped with a slide rail, which is slidably connected to the placement plate 5 via an electric slider. An electric clamping plate 6 is installed on each side of the placement plate 5. The electric clamping plate 6 consists of an electric telescopic rod and a clamping plate; the electric telescopic rod is used to move the clamping plate. The device is equipped with a connecting frame 1, which is fixedly connected to an electric push rod 7. The telescopic part of the electric push rod 7 is fixedly connected to a connecting frame 2 8, and the connecting frame 2 8 is slidably connected to the connecting frame 1 via a slide rod. The connecting frame 2 8 is fixedly connected to two drive motors 2 9. The connecting frame 2 8 is rotatably connected to two arc-shaped plates 2 10, and each of the two arc-shaped plates 2 10 is fixedly connected to the output part of a drive motor 2 9. Each arc-shaped plate 2 10 is provided with a slide rail, and an electric slide table 2 11 is slidably connected on the slide rail. The surface of the electric slide table 2 11 is provided with a slide rail, and the slide rail is slidably connected to two fixed plates 12 via an electric slider.

[0031] The fixing plate 12 has a clearance groove 1201 to facilitate welding of the connection between the rib plate 100 and the arc-shaped steel 200 by the welding torch.

[0032] The surface of the fixing plate 12 is rough, which increases the friction between it and the curved steel 200 and improves the clamping and fixing effect.

[0033] An electromagnet 51 is provided on the surface of the placement plate 5, which can magnetically fix the placed rib plate 100, thereby achieving initial fixation of the rib plate 100.

[0034] The clamping plate of the electric clamping plate 6 is configured as a trapezoidal shape that is narrower near the end of the placement plate 5 and wider away from the end of the placement plate 5. When clamping the rib plate 100, a component force toward the placement plate 5 can be applied to it to improve the clamping effect on the rib plate 100.

[0035] The working steps of the above embodiment are as follows: First, the equilateral angle steel is erected on the iron frame using lifting equipment, so that the welding area of ​​the equilateral angle steel is suspended in the air; then, the rib plate 100 is manually welded onto the equilateral angle steel; during welding, the equipment is lifted by the hoisting equipment and moved above the equilateral angle steel, then the drive motor 2 is controlled to drive the two arc plates 3 to rotate and open, and the drive motor 9 is controlled to drive the two arc plates 10 to rotate and open, then the hoisting equipment is controlled to lower the equipment and place it on the equilateral angle steel, and then the arc plates 3 and 10 are controlled to rotate and merge, as shown. Figure 1 As shown, the arc-shaped plate 3 and the arc-shaped plate 10 surround the equilateral angle steel. Then, the electric push rod 122 on the mounting block 121 is controlled to drive the electric roller 123 to move and contact the equilateral angle steel, fixing the equipment on the equilateral angle steel. The connection between the hoisting equipment and the equipment is then manually disconnected. After the equipment installation is completed, welding work is carried out. First, the electric slide table 4 is controlled to drive the placement plate 5 and other connected parts to move along the slide rail on the arc-shaped plate 3 to the upper side of the arc-shaped plate 3, so that the ribs 100 can be placed manually. Then, the ribs 100 are placed one by one manually. On the placement plate 5, the rib plate 100 is magnetically attracted by the electromagnet 51 on the placement plate 5, initially fixing it to the placement plate 5 to improve the efficiency of manual placement. After placement, the two electric clamping plates 6 on the placement plate 5 are controlled to move towards each other to clamp and fix the magnetically attracted rib plate 100. Then, the electric slide table 4 is controlled to drive the placement plate 5 and the fixed rib plate 100 to rotate along the arc plate 3, distributing the rib plate 100 in a circular array on the surface of the equilateral angle steel. Then, the electric slider is controlled to drive the placement plate 5 and the rib plate 100 to move towards the surface of the equilateral angle steel, such as... Figure 4As shown, the rib plate 100 is automatically aligned until it comes into contact with the equilateral angle steel. Then, the rib plate 100 is manually welded to the equilateral angle steel using welding equipment, thus completing the welding of the rib plate 100. In this way, by placing the rib plate 100 on the placement plate 5 and then rotating the placement plate 5 along the arc plate 3, the rib plate 100 is automatically positioned and aligned. Compared with manual placement and alignment, this can effectively improve the overall welding efficiency. Moreover, the electric clamping plate 6 keeps the rib plate 100 clamped and fixed at all times, preventing the rib plate 100 from becoming skewed due to manual touch during the welding process, thus ensuring the overall welding quality.

[0036] It also includes an electric slide table 3 101, a linear electric slider 1 102, a fixed roller 1 103, a linear electric slider 2 104, an electric motor 106, and a fixed roller 2 105; a number of electric slide tables 3 101 are slidably connected to the slide rail on the arc plate 2 10; each electric slide table 3 101 has a slide groove on its surface, and the slide groove is slidably connected to the linear electric slider 1 102 and the linear electric slider 2 104; each linear electric slider 1 102 is rotatably connected to the fixed roller 103; the linear electric slider 2 104 is fixedly connected to the electric motor 106; the output part of the electric motor 106 is fixedly connected to the fixed roller 2 105.

[0037] The surface of the fixed roller 2 105 is detachably connected with a grinding layer 10501. The grinding layer 10501 of the fixed roller 2 105 can grind the inner ring surface of the arc-shaped steel 200, thereby improving the welding quality with the rib plate 100.

[0038] It also includes mounting blocks 121, electric push rods 122 and electric rollers 123; four mounting blocks 121 arranged in a circular array are fixedly connected to the left side of the arc plate 13 and the right side of the arc plate 20; each mounting block 121 is fixedly connected to an electric push rod 122; each electric push rod 122 has an electric roller 123 installed on its telescopic part, and the electric roller 123 consists of a motor and a roller, with the motor used to drive the roller to rotate.

[0039] The electric roller 123 is equipped with a locking structure, which is an electromagnetic lock consisting of an electromagnet and a latch. When energized, the electromagnet generates a magnetic force to attract the latch, thus locking the electric roller 123 in place. When the power is off, the magnetic force disappears, the latch is released, and the electric roller 123 can rotate freely. Therefore, during welding, the electric roller 123 can be locked in place by the locking structure, improving the stability of the welding process.

[0040] The surface of the fixed roller 2 105 is provided with a grinding layer 10501. The fixed plate 12 clamps and fixes the arc-shaped steel 200. During the process of waiting for the rib plate 100 to be welded, the electric slide table 3 101 is controlled to drive the fixed roller 1 103 and the fixed roller 2 105 to reciprocate along the arc-shaped plate 2 10. At the same time, the electric motor 106 is controlled to drive the fixed roller 2 105 to rotate, and the area on the arc-shaped steel 200 that is to be welded to the rib plate 100 is ground to improve the quality of subsequent welding.

[0041] Furthermore, considering that after the welding of the reinforcing ring is completed, the welding quality still needs to be inspected to ensure the overall production quality of the communication tower steel structure; therefore, after the welding of the rib plate 100 is completed, all the placement plates 5 are then controlled to move along the electric slide table 4 away from the equilateral angle steel, thereby applying a peeling force to the weld between the rib plate 100 and the equilateral angle steel. By controlling the retraction of the electric push rod 7 and the rotation of the electric roller 123 on the arc plate 3, the placement plates 5 are moved laterally along the equilateral angle steel, applying a thrust along the axial direction of the equilateral angle steel to the welded rib plate 100, thereby inspecting the welding condition at the joint between the rib plate 100 and the equilateral angle steel and ensuring the overall welding quality; after the rib plate 100 is completed... After testing the welding quality of the equilateral angle steel, the arc-shaped steel 200 is then welded. After welding, the electric clamping plate 6 on the placement plate 5 is controlled to clamp and fix the rib 100. Then, the electric slide table 3 101 is controlled to drive the fixed roller 1 103 and the fixed roller 2 105 to move along the arc-shaped plate 2 10, so that the electric slide table 3 101 and the electric slide table 2 11 are equidistantly distributed on the arc-shaped plate 2 10. Then, the two fixed plates 12, as well as the fixed roller 1 103 and the fixed roller 2 105, are controlled to move away from the equilateral angle steel, thereby applying force to the welding part of the rib 100 and the arc-shaped steel 200, and detecting the welding quality of this part, thus ensuring the overall quality of the communication tower steel structure welding.

[0042] Example 2: Based on Example 1, referring to... Figure 7 As shown, it also includes a suction tube 201; each electric slide 3 101 is fixedly connected to a suction tube 201, and the suction tube 201 is connected to an external suction mechanism.

[0043] Based on the above embodiment 1, considering that when the inner ring surface of the arc-shaped steel 200 is ground by the grinding layer 10501 of the fixed roller 2 105, the grinding dust will fall on the surface of the equilateral angle steel, thus affecting the welding of the rib plate 100 and the equilateral angle steel, during the grinding process of the grinding layer 10501, the external suction mechanism is controlled to work, and the dust generated by the suction pipe 201 is used to suck up the dust generated by the grinding, thereby preventing the debris from falling on the equilateral angle steel and affecting the quality of subsequent welding.

The scope of the following claims should be given the broadest interpretation so as to cover all variations and equivalent structures and functions.
