Description

Technical Field

[0001] This utility model relates to the technical field of steel structure welding devices, specifically a steel structure welding device for municipal road and bridge construction. Background Technology

[0002] In modern urban construction, the scale of municipal road and bridge construction is constantly expanding. In order to meet the increasing traffic flow and urban development needs, the requirements for the strength and stability of road and bridge structures are getting higher and higher. Steel structures are widely used in municipal road and bridge construction due to their advantages such as high strength, light weight and recyclability.

[0003] The unloading process of traditional welding equipment requires manual intervention. After welding is completed, workers need to move the welded workpiece away and then put in the workpiece to be processed. This process will leave the welding equipment idle for a long time, which will reduce the overall work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a steel structure welding device for municipal road and bridge construction, which solves the problem that the unloading process of traditional welding devices requires manual intervention. After welding is completed, workers need to move the welded workpiece away first and then put in the workpiece to be processed. This process will leave the welding device in an idle state for a long time, which will lead to a reduction in overall work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a steel structure welding device for municipal road and bridge construction, comprising a base, a bracket fixedly installed on the upper surface of the base, a welding mechanism installed inside the bracket, and two placement platforms fixedly installed on the upper surface of the base. A first cylinder is fixedly installed on the upper surface of each placement platform, the output end of the first cylinder extending into the interior of the placement platform, and a clamping plate fixedly installed at the output end of the first cylinder. A unloading mechanism is installed inside the base, and the unloading end of the unloading mechanism is located between the two placement platforms.

[0007] Furthermore, the unloading mechanism includes a lead screw, which is rotatably connected to the inside of the lead screw. A guide slide is fixedly installed inside the base, and a first motor is fixedly installed on the outer surface of the base. The output end of the first motor is fixedly connected to one end of the lead screw.

[0008] Furthermore, a movable plate is slidably connected inside the base. One end of the movable plate is slidably connected to a guide slide rod, and the other end of the movable plate is threadedly connected to a lead screw. A second cylinder is fixedly installed inside the movable plate.

[0009] Furthermore, an auxiliary telescopic rod is fixedly installed inside the movable plate, and the number of the auxiliary telescopic rods is fixed at two.

[0010] Furthermore, a mounting shell is fixedly installed at the output end of the second cylinder. The lower surface of the mounting shell is connected to one end of two auxiliary telescopic rods. A bidirectional lead screw is rotatably connected inside the mounting shell. A second motor is fixedly installed at one end of the mounting shell. The output end of the second motor is connected to one end of the bidirectional lead screw.

[0011] Furthermore, the mounting housing has two unloading plates that are slidably connected inside. The two unloading plates are respectively threaded onto the positive and negative threads of the bidirectional lead screw, and the two unloading plates are disposed between the two placement platforms.

[0012] This utility model has the following beneficial effects:

[0013] (1) After welding is completed, the unloading operation begins. The first motor is started and drives the lead screw to rotate. Since the lead screw is threadedly connected to the moving plate and the moving plate is slidably connected to the guide slide, the guide slide plays a guiding role and restricts the moving plate to move only along the axial direction of the lead screw. Therefore, the rotation of the lead screw will cause the moving plate to move between the two placement platforms. Once the moving plate is in the appropriate position, the second cylinder is activated. The output of the second cylinder pushes the mounting shell downwards. Simultaneously, the movement of the mounting shell extends the auxiliary telescopic rod, bringing the mounting shell closer to the welded workpiece. Then, the second motor is activated, driving the bidirectional lead screw to rotate. Since the two unloading plates are threaded onto the positive and negative threads of the bidirectional lead screw respectively, the rotation of the lead screw causes the two unloading plates to move towards or away from each other inside the mounting shell. When the two unloading plates clamp the welded workpiece, the first motor is activated to move the moving plate out, thus removing the workpiece clamped by the unloading plates. The worker then places the workpiece to be processed inside the table for the next welding cycle. Afterward, the unloading plates are released, and the welded workpiece is removed. This avoids the need for manual removal of the processed workpiece before placing the workpiece to be processed for the next welding cycle, which previously kept the welding mechanism idle for extended periods, leading to reduced work efficiency.

[0014] (2) This utility model drives the bidirectional lead screw to rotate through the second motor. Since the two unloading plates are respectively threaded to the positive and negative threads of the bidirectional lead screw, the rotation of the bidirectional lead screw will cause the two unloading plates to move towards or away from each other inside the mounting shell, which can clamp the workpiece and improve the stability of unloading the workpiece.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a steel structure welding device for municipal road and bridge construction, including a base 1, a bracket 2 fixedly installed on the upper surface of the base 1, a welding mechanism 3 installed inside the bracket 2, a placement platform 4 fixedly installed on the upper surface of the base 1, the number of placement platforms 4 is fixedly two, a first cylinder 5 fixedly installed on the upper surface of each placement platform 4, the output end of the first cylinder 5 extends into the interior of the placement platform 4, a clamping plate 6 fixedly installed on the output end of the first cylinder 5, and a unloading mechanism 7 installed inside the base 1, the unloading end of the unloading mechanism 7 is located between the two placement platforms 4;

[0025] The unloading mechanism 7 includes a lead screw 701, which is rotatably connected inside the lead screw 701. A guide slide rod 702 is fixedly installed inside the base 1. A first motor 703 is fixedly installed on the outer surface of the base 1. The output end of the first motor 703 is fixedly connected to one end of the lead screw 701.

[0026] The base 1 has a sliding connection to a movable plate 704. One end of the movable plate 704 is slidably connected to a guide slide rod 702, and the other end of the movable plate 704 is threadedly connected to a lead screw 701. A second cylinder 705 is fixedly installed inside the movable plate 704.

[0027] An auxiliary telescopic rod 706 is fixedly installed inside the movable plate 704, and the number of auxiliary telescopic rods 706 is fixed to two.

[0028] The output end of the second cylinder 705 is fixedly mounted with a mounting shell 707. The lower surface of the mounting shell 707 is connected to one end of the two auxiliary telescopic rods 706. The interior of the mounting shell 707 is rotatably connected with a double-acting screw 708. One end of the mounting shell 707 is fixedly mounted with a second motor 709. The output end of the second motor 709 is connected to one end of the double-acting screw 708.

[0029] The mounting housing 707 has two sliding connections inside, with the two unloading plates 710 respectively threaded onto the positive and negative threads of the double-acting screw 708. The two unloading plates 710 are positioned between the two placement platforms 4.

[0030] After welding is completed, the unloading operation begins. The first motor 703 is started, which drives the lead screw 701 to rotate. Since the lead screw 701 is threadedly connected to the moving plate 704 and the moving plate 704 is slidably connected to the guide slide rod 702, the guide slide rod 702 plays a guiding role, restricting the moving plate 704 to move only along the axial direction of the lead screw 701. Therefore, the rotation of the lead screw 701 will cause the moving plate 704 to move between the two placement platforms 4. Once the movable plate 704 has moved to the appropriate position, the second cylinder 705 is activated. The output end of the second cylinder 705 pushes the mounting shell 707 downward. Simultaneously, the movement of the mounting shell 707 causes the auxiliary telescopic rod 706 to extend, bringing the mounting shell 707 closer to the welded workpiece. Next, the second motor 709 is activated, driving the bidirectional lead screw 708 to rotate. Since the two unloading plates 710 are threaded onto the positive and negative threads of the bidirectional lead screw 708 respectively, the rotation of the bidirectional lead screw 708 will cause the two unloading plates 710 to move towards or away from each other inside the mounting shell 707. When the two unloading plates 710 clamp the welded workpiece, the first motor 703 is started to move the moving plate 704 out, which moves the workpiece clamped by the unloading plates 710 out. Then, the worker places the workpiece to be processed inside the table 4 to perform the next set of welding. Then the unloading plates 710 are released and the welded workpiece is taken out and removed. This avoids the situation in the existing technology where the processed workpiece needs to be moved away manually before the workpiece to be processed is put in for the next set of welding, which keeps the welding mechanism 3 in a long idle state and reduces work efficiency.

[0031] In use, first place two workpieces on the two placement tables 4, then push them to the docking state, with the docking gap below the welding head of the welding mechanism 3. Then start the first cylinder 5. The output end of the first cylinder 5 pushes the clamping plate 6. Since the first cylinder 5 is installed on the placement table 4, the clamping plate 6 will move towards the workpiece, thus firmly clamping the workpiece on the placement table 4, ensuring that the workpiece will not be displaced during the welding process. After the workpiece is clamped, the welding mechanism 3 starts to work and performs welding operations on the steel structure workpiece on the placement table 4.

[0032] After welding is completed, the unloading operation begins. The first motor 703 is started, which drives the lead screw 701 to rotate. Since the lead screw 701 is threadedly connected to the moving plate 704 and the moving plate 704 is slidably connected to the guide slide rod 702, the guide slide rod 702 plays a guiding role, restricting the moving plate 704 to move only along the axial direction of the lead screw 701. Therefore, the rotation of the lead screw 701 will cause the moving plate 704 to move between the two placement platforms 4. Once the movable plate 704 has moved to the appropriate position, the second cylinder 705 is activated. The output end of the second cylinder 705 pushes the mounting shell 707 downward. Simultaneously, the movement of the mounting shell 707 causes the auxiliary telescopic rod 706 to extend, bringing the mounting shell 707 closer to the welded workpiece. Next, the second motor 709 is activated, driving the bidirectional lead screw 708 to rotate. Since the two unloading plates 710 are threaded onto the positive and negative threads of the bidirectional lead screw 708 respectively, the rotation of the bidirectional lead screw 708 will cause the two unloading plates 710 to move towards or away from each other inside the mounting shell 707. When the two unloading plates 710 clamp the welded workpiece, the first motor 703 is started to move the moving plate 704 out, which moves the workpiece clamped by the unloading plates 710 out. Then, the worker places the workpiece to be processed inside the table 4 to perform the next set of welding. Then the unloading plates 710 are released and the welded workpiece is taken out and removed. This avoids the situation in the existing technology where the processed workpiece needs to be moved away manually before the workpiece to be processed is put in for the next set of welding, which keeps the welding mechanism 3 in a long idle state and reduces work efficiency.
