Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically to an intelligent cover plate frame welding device. Background Technology

[0002] Manhole covers are mainly used in power, telecommunications, and municipal applications to seal the openings of underground manholes and ensure a level surface. To improve the load-bearing capacity of the manhole covers, they are generally composed of a frame and concrete. The frame enhances the compressive strength of the concrete, ensuring the manhole cover is not easily broken and has a long service life.

[0003] In related technologies, cover plate frames are generally made of welded steel. Welding of cover plate frames is mostly done manually. However, there are many welding points in the cover plate frame, which makes manual welding slow and poses safety and health hazards. In addition, the position of the steel must be carefully considered. If welding operation is incorrect, it is easy to cause certain deviations in the formed cover plate frame structure, resulting in unstable cover plate frame quality. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent cover plate frame welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent cover plate frame welding device, comprising a base, an ejector mounted on the base, a fixing plate mounted on the ejector, four positioning plates and four placement seats on the surface of the fixing plate, a pre-reserved gap between the positioning plates and the placement seats, a steel plate placed between the positioning plates and the placement seats, and reinforcing bars placed on the placement seats to ensure accurate welding position, improve welding quality and consistency of finished products. After welding is completed, the ejector pushes out the cover plate frame for easy removal of the finished product.

[0006] A support rod is connected to a base, and a three-axis controller is installed on the support rod. The three-axis controller is connected to a fixing head, and a welding head is installed on the fixing head. The three-axis controller controls the movement of the welding head, and the welding head welds steel plates and reinforcing bars. Welding is performed on steel plates and reinforcing bars at different positions to meet diverse welding needs and improve the continuity and automation of welding.

[0007] An assembly base is mounted on a three-axis controller. The assembly base is equipped with a welding wire spool and a conveyor. The welding head is connected to the assembly base. The conveyor feeds the welding wire from the welding wire spool into the welding head, ensuring that the welding wire can be supplied smoothly to the welding head and providing the necessary materials for the welding process.

[0008] Furthermore, the ejector includes four cylinders, with the piston rods of the cylinders passing through a fixed plate. The fixed plate is mounted on the cylinder housing, and the four cylinders are located at the four corners of the fixed plate. When ejecting the cover plate frame, the force is evenly distributed, avoiding deformation due to uneven force and ensuring the quality of the finished product.

[0009] Furthermore, the placement seat is provided with several evenly arranged positioning slots. The positioning slots position the two ends of the reinforcing bars, improving the placement accuracy of the reinforcing bars before welding, ensuring the accurate position of the welding points, thereby improving the welding quality and the overall strength of the cover plate frame. The evenly arranged positioning slot design also makes it convenient for operators to place the reinforcing bars quickly and accurately, improving work efficiency.

[0010] Furthermore, the surface of the fixing plate is provided with two auxiliary seats, and the auxiliary seats have an integrally formed boss in the middle, which can play an auxiliary positioning role for the cover plate frame, which is conducive to improving the welding accuracy and finished product quality.

[0011] Furthermore, the three-axis controller includes left and right lead screw slides, front and rear lead screw slides, and upper and lower lead screw slides. The left and right lead screw slides are mounted on the support rod, the front and rear lead screw slides are mounted on the left and right lead screw slides, and the upper and lower lead screw slides are mounted on the front and rear lead screw slides. The mounting base is connected to the front and rear lead screw slides and the upper and lower lead screw slides. The modular lead screw slide structure facilitates installation, debugging, and maintenance, reducing the difficulty of equipment maintenance.

[0012] Furthermore, the conveyor includes a fixed base, on which two feeding motors and a driven wheel are mounted. The feeding motors are equipped with a driving wheel. The rotation of the driving wheel drives the welding wire to move towards the welding head, which can provide stable and continuous welding wire feeding power, ensuring that the welding wire can be delivered to the welding head in a timely and accurate manner according to the welding requirements, and avoiding problems such as insufficient welding wire supply or jamming.

[0013] Furthermore, a corrugated sleeve is fitted onto the upper and lower lead screw slides. The corrugated sleeve is connected to the fixed head to prevent foreign objects such as sparks and slag generated during the welding process, ensuring the normal operation of the three-axis controller, thereby improving the stability and reliability of the welding equipment.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The left and right lead screw slides, front and rear lead screw slides, and upper and lower lead screw slides can control the movement of the welding head in three-dimensional space to realize automated welding of the cover plate skeleton. There is no need for manual spot welding operation, which increases the welding speed and quickly completes the welding work of many welding points on the cover plate skeleton. The conveyor can stably feed the welding wire from the welding wire spool into the welding head, ensuring that the welding wire supply is uninterrupted during the welding process, ensuring continuous welding work and improving production efficiency.

[0016] (2) Through automated welding, operators only need to set the parameters of the equipment and place the reinforcing bars and steel plates. They do not need to stay in the welding work area for a long time, which reduces contact with the dangerous welding environment, reduces the probability of safety accidents and the damage to the health of operators. The cylinder starts to push out the cover plate frame, and it is more convenient to remove the cover plate frame.

[0017] (3) Positioning the reinforcing bars and steel plates by positioning plates and placement seats ensures accurate welding positions and avoids steel displacement during welding. Compared with manual placement of steel, which is prone to positional deviation, this method can effectively ensure the accuracy of welding point positions, making the formed cover plate skeleton structure more standardized and improving the stability of cover plate skeleton quality.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example:

[0027] Please see Figure 1-6 The present invention provides a technical solution: an intelligent cover plate frame welding equipment, including a base 1, the base 1 having space for installing some peripheral equipment, an ejector installed on the base 1, and a fixing plate 16 installed on the ejector. The ejector automatically ejects the cover plate frame without the need for manual removal of the cover plate frame, making it convenient to transport.

[0028] The surface of the fixed plate 16 is provided with four positioning plates 10 and four placement seats 11. A gap is reserved between the positioning plates 10 and the placement seats 11. A steel plate is placed between the positioning plates 10 and the placement seats 11. Reinforcing bars are placed on the placement seats 11 to realize the preset position of the reinforcing bars and steel plates, providing the welding equipment with the reinforcing bars and steel plates required for welding, so that the welding equipment can weld the preset welding points and realize the automatic welding of the cover plate frame.

[0029] Support rod 2 is connected to base 1. A three-axis controller is installed on support rod 2. The three-axis controller is connected to a fixed head 7. A welding head 8 is installed on the fixed head 7. Support rod 2, together with the three-axis controller, fixed head 7 and welding head 8, can realize the flexible movement of welding head 8 in three-dimensional space. Welding head 8 welds steel plates and steel bars. The welding speed is fast and the production efficiency of cover plate frame is high.

[0030] The assembly base 12 is mounted on the three-axis controller. The assembly base 12 is equipped with a welding wire spool 13 and a conveyor. The welding head 8 is connected to the assembly base 12. The conveyor feeds the welding wire from the welding wire spool 13 into the welding head 8. The welding wire spool 13 is wound with a certain length of welding wire, which is longer than the welding rod used for manual welding. This can significantly extend the time for changing the welding wire spool 13, allowing the welding equipment to work continuously for a longer time and reducing the number of downtimes.

[0031] In this embodiment, as Figure 3 As shown, the ejector includes four cylinders 9. The piston rods of the cylinders 9 pass through the fixing plate 16, which is mounted on the housing of the cylinders 9. The four cylinders 9 are located at the four corners of the fixing plate 16 and are aligned with the four corners of the cover plate frame. When the cover plate frame is not fully welded, the piston rods of the cylinders 9 retract, which will not affect the placement of the steel plate. When the cover plate frame is completed, the four cylinders 9 simultaneously lift the cover plate frame to ensure that the cover plate frame will not get stuck between the positioning plate 10 and the placement seat 11, making it easier to remove the cover plate frame.

[0032] In this embodiment, as Figure 3 As shown, the placement seat 11 is provided with a number of evenly arranged positioning grooves 14. The positioning grooves 14 position the two ends of the steel bars. The positioning grooves 14 are arranged at intervals, which can control the spacing of the steel bars, making the cover plate frame specifications more consistent and reducing the difficulty for workers to place the steel bars.

[0033] In this embodiment, as Figure 3and Figure 6 As shown, the surface of the fixing plate 16 is provided with two auxiliary seats 15. The auxiliary seat 15 has an integrally formed boss in the middle. The cover plate frame has two square tubes. The square tubes are placed on the boss to position them and facilitate welding them to the reinforcing bars.

[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the three-axis controller includes left and right lead screw slides 3, front and rear lead screw slides 4, and upper and lower lead screw slides 5. The left and right lead screw slides 3, front and rear lead screw slides 4, and upper and lower lead screw slides 5 are equipped with servo motors. The left and right lead screw slides 3 are mounted on the support rod 2, the front and rear lead screw slides 4 are mounted on the left and right lead screw slides 3, and the upper and lower lead screw slides 5 are mounted on the front and rear lead screw slides 4. The mounting base 12 is connected to the front and rear lead screw slides 4 and the upper and lower lead screw slides 5. An n-shaped seat is mounted on the left and right lead screw slides 3, and the mounting base 12 is connected to the upper surface of the n-shaped seat. The front and rear lead screw slides 4 are mounted on the lower surface of the n-shaped seat, so that the welding wire spool 13 and the welding head 8 move left and right synchronously to ensure stable welding wire supply.

[0035] The combination of left and right lead screw slides 3, front and rear lead screw slides 4, and upper and lower lead screw slides 5 is a mature and highly precise structure that enables the welding head 8 to move and position precisely in three dimensions, thereby meeting the requirements of complex welding trajectories and allowing the welding equipment to weld cover plate skeletons of different shapes and specifications.

[0036] In this embodiment, as Figure 5 As shown, the conveyor includes a fixed base 17, on which two feeding motors 18 and a driven wheel 19 are mounted. A driving wheel 20 is mounted on the feeding motor 18. The feeding motor 18 drives the driving wheel 20 to rotate. The welding wire is located between the driven wheel 19 and the driving wheel 20. The rotation of the driving wheel 20 drives the welding wire to move towards the welding head 8.

[0037] In this embodiment, as Figure 1 As shown, a corrugated sleeve 6 is fitted onto the upper and lower lead screw slides 5. The corrugated sleeve 6 is connected to the fixed head 7. When the fixed head 7 and the welding head 8 move up and down, the corrugated sleeve 6 can extend and retract without affecting the lifting and lowering of the welding head 8. The welding sparks and slag are blocked by the corrugated sleeve 6, which can prevent damage to the upper and lower lead screw slides 5. The upper and lower lead screw slides 5 work stably, reducing the failure rate of the welding equipment.

[0038] Specifically, during use, the steel plate is placed on the fixed plate 16 at the reserved gap between the positioning plate 10 and the placement seat 11; the reinforcing bars are placed on the placement seat 11, and the two ends of the reinforcing bars are positioned by the evenly distributed positioning grooves 14 on the placement seat 11, thereby controlling the spacing of the reinforcing bars; the square tube is placed on the protrusion in the middle of the auxiliary seat 15 on the surface of the fixed plate 16 for positioning, in preparation for welding.

[0039] Two feeding motors 18 drive the drive wheel 20 to rotate. The welding wire is between the driven wheel 19 and the drive wheel 20. When the drive wheel 20 rotates, it drives the welding wire to move towards the welding head 8, ensuring that the welding head 8 has a continuous supply of welding wire.

[0040] The welding head 8 is controlled by the left and right lead screw slides 3, the front and rear lead screw slides 4, and the upper and lower lead screw slides 5. The welding head 8 moves flexibly and precisely in three-dimensional space. The welding head 8 welds the positioned steel plate and reinforcing bar according to the preset welding trajectory and parameters, so as to realize the automatic welding of the cover plate skeleton.

[0041] After the cover plate frame is welded, the four cylinders 9 located at the four corners of the fixed plate 16 start to work. The piston rods of the cylinders 9 extend and simultaneously lift the cover plate frame, pushing the cover plate frame upward. Since the lifting is aligned with the four corners of the cover plate frame, it can ensure that the cover plate frame will not get stuck between the positioning plate 10 and the placement seat 11, making it convenient for operators to remove and move it.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
