Description

Technical Field

[0001] The utility model relates to the technical field of angle steel production, in particular to an auxiliary feeding mechanism for angle steel. Background Art

[0002] Angle steel is a commonly used profile in the field of power tower manufacturing. During the production process of angle steel, it needs to be cut to size. Generally, a conveyor belt is set at the front end of the cutting device, and then the angle steel material is placed on the conveyor belt and transported to the cutting device for cutting.

[0003] Since angle steel materials are long and heavy, when loading them onto a conveyor belt, they are generally carried to the conveyor belt by multiple people working together. This method of loading has high labor intensity and low loading efficiency, especially for some large-sized angle steel materials. If the angle steel materials fall during manual handling, they can easily injure workers, and the workers' personal safety cannot be guaranteed. Utility Model Content

There are clamping assemblies on multiple gantries, which are more stable for the clamping and transportation of long strips of angle steel materials. This solution greatly reduces the labor intensity of workers when loading angle steel, thereby improving the loading efficiency. At the same time, there is no need for manual handling and loading, which avoids the risk of angle steel falling and injuring workers, and ensures the personal safety of workers.

[0024] Example

[0025] An auxiliary feeding mechanism for angle steel includes a feeding mechanism arranged in front of a conveyor belt 1, the feeding mechanism includes a plurality of gantries 2 distributed in a straight line, a roller 8 is provided at the bottom end of the gantry 2, a guide rail 5 is fixed to the top of the gantry 2, the guide rail 5 is parallel to the transport direction of the conveyor belt 1, a transport component 6 is slidably provided on the guide rail 5, a clamping component 7 for magnetically adsorbing the angle steel material below is connected below the transport component 6, and the clamping component 7 can move vertically.

[0026] In this embodiment, Figure 1 and Figure 2 As shown, the loading mechanism is composed of a plurality of gantries 2 distributed in a straight line, and the guide rail 5 connects the gantries 2 into a whole. A roller 8 is provided at the bottom of each gantry 2, and the roller 8 can facilitate the movement of the gantry 2. The roller 8 is a universal wheel, and the universal wheel is bolted to the bottom end of the gantry 2. A worker can push the gantry 2 to a suitable loading position. The guide rail 5 is fixed on the top of the gantry 2 and is parallel to the transportation direction of the conveyor belt 1, providing a stable moving path for the transport component 6. The transport component 6 slides on the guide rail 5 and can be easily moved along the direction of the conveyor belt 1. The clamping component 7 can ensure that the angle steel material below is stable and does not fall off during transportation by magnetic absorption. The clamping component 7 can also move vertically to grasp and release the angle steel material. When loading, the angle steel material is accumulated at the front end of the conveyor belt 1, the loading mechanism is pushed above the angle steel material, and then the clamping assembly 7 moves downward close to the angle steel material, and then the angle steel material is clamped, and the clamping assembly 7 moves up. The worker can directly push the gantry 2 above the conveyor belt 1, and then place the angle steel material on the conveyor belt 1, or move the angle steel material to the conveyor belt 1 horizontally through the transportation assembly 6. There are clamping assemblies 7 on multiple gantries 2, which are more stable for the clamping and transportation of long strips of angle steel materials. This solution greatly reduces the labor intensity of workers when loading the angle steel, thereby improving the loading efficiency. At the same time, there is no need for manual handling and loading, which avoids the risk of angle steel falling and injuring workers, thereby ensuring the personal safety of workers.

[0027] Furthermore, the guide rail 5 is an angle steel, the top corner of the angle steel is welded and fixed to the middle position of the top end of the gantry 2, the opening of the angle steel faces downward, and the transport component 6 is slidably connected to the two outer side surfaces of the angle steel.

[0028] Specifically, angle steel is chosen as the material for the guide rail 5 mainly because angle steel has good strength and stability and relatively low cost. The top angle of the angle steel is welded and fixed to the middle position of the top end of the gantry 2. This connection method is simple and firm, and can ensure the stability and reliability of the guide rail 5. The opening of the angle steel faces downward, and the transport component 6 is slidably connected to the two outer sides of the angle steel to ensure that it can move smoothly back and forth on the angle steel guide rail 5. This connection method is simple and reliable, and can meet the needs of automatic loading.

[0029] Furthermore, the transport component 6 includes an arc-shaped plate 13 and a bearing 4. The two ends of the arc-shaped plate 13 are located on the outside of the angle steel. Support rods 9 are provided on the inner sides of the two ends of the arc-shaped plate 13. The support rods 9 are perpendicular to the arc-shaped plate 13. The ends of the support rods 9 are connected to the bearing 4. The bearing 4 contacts the side of the angle steel. The bottom end of the arc-shaped plate 13 is connected to the clamping component 7.

[0030] Specifically, Figure 2 As shown, the two ends of the arc plate 13 are located on the outside of the angle steel to prevent the guide rail 5 from affecting the sliding of the arc plate 13. At the same time, the shape of the arc plate 13 helps to disperse the load and improve the carrying capacity of the entire transport component 6. The support rod 9 is vertically connected to the inner side of the arc plate 13, and the bearing 4 installed at its end is in contact with the side of the guide rail 5. The design of the bearing 4 allows the transport component 6 to slide easily on the angle steel guide rail 5, reducing friction and resistance and improving transportation efficiency. At the same time, the bearing 4 also has a certain durability and can cope with long-term and high-frequency use. The bottom end of the arc plate 13 is connected to the clamping component 7. This connection method ensures the stability and accuracy of the clamping component 7 during movement. The clamping component 7 absorbs the angle steel material through magnetic force, and the transport component 6 is responsible for moving the clamping component 7 and the angle steel material absorbed by it along the guide rail 5 smoothly to the conveyor belt 1, thereby realizing auxiliary loading, reducing the labor intensity of workers and improving loading efficiency.

[0031] Furthermore, the clamping assembly 7 includes a telescopic cylinder 12 and a clamping plate 11 . The telescopic cylinder 12 is fixed to the bottom surface of the arc-shaped plate 13 , and the telescopic end of the telescopic cylinder 12 is connected to the clamping plate 11 .

[0032] Furthermore, the bottom surface of the clamping plate 11 is formed with an inverted V shape adapted to the angle steel material, and the electromagnet plate 10 is fixed to the bottom surface of the clamping plate 11 .

[0033] Specifically, the telescopic cylinder 12 is fixed to the bottom surface of the arc plate 13, and its telescopic end is connected to the clamping plate 11, so that the clamping plate 11 can be moved vertically as needed, so as to facilitate the clamping of the angle steel material. The telescopic cylinder 12 has the characteristics of precise control and stable operation, which can ensure the accuracy and stability of the clamping plate 11 during the movement. The inverted V-shaped design of the bottom surface of the clamping plate 11 is adapted to the shape of the angle steel material. This shape can ensure the close fit between the clamping plate 11 and the angle steel, preventing the angle steel from sliding or falling off during the transmission process. At the same time, the inverted V-shaped design can also adapt to angle steels of different sizes, increasing the versatility and flexibility of the clamping assembly 7. An electromagnet plate 10 is fixed on the bottom surface of the clamping plate 11. The electromagnetic force generated by the electromagnet plate 10 after being energized can adsorb the angle steel material, thereby realizing automatic clamping and releasing of the angle steel. The electromagnet plate 10 has the characteristics of fast response speed and strong adsorption force, thereby ensuring the stability and safety of the angle steel during the transmission process. At the same time, by controlling the on and off of the electromagnet, the opening and closing operation of the clamping plate 11 can be conveniently realized, thereby improving work efficiency.

[0034] Furthermore, limit plates 3 are provided at both ends of the guide rail 5 .

[0035] Specifically, the main function of the limit plate 3 is to limit the movement range of the bearing 4. When the moving part of the arc plate 13 reaches the end of the guide rail 5, the limit plate 3 will prevent it from continuing to move, thereby preventing the equipment from falling due to exceeding its design range and preventing the clamping assembly 7 from being damaged.

[0036] Furthermore, a wear-resistant layer made of polytetrafluoroethylene is coated on the side of the guide rail 5 that contacts the bearing 4 .

[0037] Specifically, polytetrafluoroethylene (PTFE) is a material with excellent wear resistance. Its molecular structure makes it have an extremely low friction coefficient and excellent sliding performance, which can effectively reduce the friction and wear between the guide rail 5 and the bearing 4. Therefore, coating the PTFE wear-resistant layer on the side of the guide rail 5 can significantly improve the wear resistance of the guide rail 5, reduce the heat and noise generated by friction, and thus extend the service life of the guide rail 5. Secondly, the PTFE material also has good chemical stability and corrosion resistance. It can resist the erosion of a variety of chemical substances and is not easy to react with lubricating oil or other media, thereby keeping the surface of the guide rail 5 clean and smooth. This helps to reduce the risk of failure of the guide rail 5 due to corrosion or pollution and improve the reliability and stability of the equipment. In addition, the guide rail 5 coated with the PTFE wear-resistant layer also has a lower maintenance cost. Due to the wear resistance and stability of the PTFE material, the guide rail 5 is not easy to wear or damage during use, reducing the frequency of replacement and maintenance, which not only reduces the maintenance cost, but also improves the operating efficiency of the equipment.

[0038] Furthermore, at least one clamping plate 11 is provided along the length direction of the gantry 2 .

[0039] Specifically, firstly, a plurality of clamping plates 11 can clamp a plurality of angle steels at the same time, thereby realizing batch loading and greatly improving production efficiency. A plurality of clamping plates 11 are arranged in the length direction of the gantry 2, and the spacing between the clamping plates 11 can be adjusted according to actual needs to adapt to angle steels of different lengths or quantities. Secondly, the presence of a plurality of clamping plates 11 also makes the loading process more stable and reliable. Since each clamping plate 11 can work independently, when a clamping plate 11 fails or needs maintenance, the other clamping plates 11 can still continue to work, which will not cause much impact on the entire loading process. In addition, this design also has a certain degree of flexibility. According to actual production needs, the number of clamping plates 11 can be easily increased or decreased to adapt to production tasks of different scales. At the same time, the position of the clamping plates 11 can also be fine-tuned to meet specific process requirements.

[0040] The working principle of the utility model is as follows: each gantry 2 is pushed to the front of the conveyor belt 1, and the telescopic cylinder 12 is controlled to move downward, so that the clamping plate 11 contacts the angle steel material below, and the inverted V-shape on the clamping plate 11 fits with the angle steel material. The electromagnetic iron plate 10 is energized to generate electromagnetic force to adsorb the angle steel material, and the telescopic cylinder 12 retracts to separate the angle steel material from the ground. Then the worker pushes the angle steel material to move above the conveyor belt 1, and the bearing 4 slides on the guide rail 5 and drives the arc plate 13 to move, thereby driving the lowered angle steel material to move along the transportation direction of the conveyor belt 1. After the angle steel material is located above the conveyor belt 1, the telescopic cylinder 12 extends, so that the angle steel material is placed on the conveyor belt 1, and the electromagnetic iron plate 10 is powered off. The angle steel material is driven by the conveyor belt 1 to be transported to the next process, which greatly reduces the labor intensity of the workers, thereby improving the loading efficiency. At the same time, there is no need for manual handling and loading, which avoids the risk of angle steel falling and injuring workers, thereby ensuring the personal safety of workers.

[0041] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
