Description

Technical Field

[0001] This utility model relates to the field of anti-falling object net processing technology, specifically an anti-falling object net welding and grinding device. Background Technology

[0002] Falling object netting is a metal protective facility installed on both sides of bridges, primarily used to prevent objects from falling and affecting the safety of traffic routes below. Its structure consists of an upper frame and a lower welded structure, forming a complete protective system through column supports and auxiliary structures. It is woven and welded using low-carbon steel wire or aluminum-magnesium alloy wire, and the surface is hot-dip galvanized and plastic-coated, giving it corrosion resistance and UV resistance.

[0003] After the anti-falling object net is welded, workers need to use a handheld angle grinder to grind the welded areas at the four corners of the net to improve the flatness of the net frame and facilitate subsequent plastic coating. When grinding the welded areas, workers need to walk around the net with a small handheld angle grinder while grinding, which is inefficient. Therefore, it is necessary to design an anti-falling object net welding and grinding device to improve the above problems. Utility Model Content

[0025] In the following description, embodiments of the anti-falling object net welding and grinding device of the present invention will be described with reference to the accompanying drawings.

[0026] Figure 1-5 This invention illustrates an embodiment of a welding and grinding device for anti-falling object nets, comprising:

[0027] The system consists of a base plate 1 and a net body 2. A lifting platform 3 is mounted on the top of the base plate 1, allowing it to slide back and forth. Specifically, sliding blocks 9 are fixedly installed on both the left and right sides of the bottom of the lifting platform 3. A guide rail 10, which works in conjunction with the sliding blocks 9, is fixedly installed on the top of the base plate 1. Multiple rollers 91 are mounted on the surface of the sliding blocks 9, rolling within the guide rail 10. By using the rollers 91, when the lifting platform 3 is pushed to move the net body 2, the rollers 91 roll within the guide rail 10, thus improving the smoothness of the user's movement when pushing the lifting platform 3. The anti-falling object net body 2 is placed on the top of the lifting operating platform 3. A grinding component 6 is set on the top of the base plate 1. The grinding component 6 slides left and right on the top of the base plate 1. Specifically, support plates 4 are fixedly installed on both the left and right sides of the top of the base plate 1. A guide column 5 is fixedly installed between the two support plates 4. The grinding component 6 slides on the surface of the guide column 5. A ball screw 7 is also rotatably connected between the two support plates 4. A ball screw nut is installed on the grinding component 6. The ball screw nut is threadedly connected to the surface of the ball screw 7. A motor 8 is fixedly installed on the surface of the support plate 4. The output shaft of the motor 8 is fixedly installed to one end of the ball screw 7.

[0028] Specifically, the grinding assembly 6 includes a mounting base 61 that slides on the top of the base plate 1. A drive wheel 62 is rotatably connected to the front of the mounting base 61. A mounting bracket 63 is fixedly mounted on the right side of the mounting base 61. Two driven wheels 64 are rotatably connected to the front of the mounting bracket 63. An adjusting rod 69 is fixedly mounted in the middle of the mounting base 61. An adjusting wheel 65 is mounted on the front of the adjusting rod 69 and slides up and down on the front of the adjusting rod 69. A grinding belt 66 is fitted on the surfaces of the drive wheel 62, driven wheels 64, and adjusting wheel 65. A cylinder 67 is fixedly mounted on the front of the mounting base 61. A pressure block assembly 68 is mounted on the output end of the cylinder 67. The pressure block assembly 68 moves down and squeezes the grinding belt 66 to deform it, thereby achieving the grinding belt 66 pressing against the anti-falling net body 2. For grinding, specifically, the pressure block assembly 68 includes a connecting plate 681 fixedly installed at the output end of the cylinder 67. A U-shaped pressure plate 682 is provided at the bottom of the connecting plate 681. The U-shaped pressure plate 682 and the connecting plate 681 are connected by multiple elastic telescopic rods 683. Multiple rollers 684 are installed at the bottom of the U-shaped pressure plate 682. The rollers 684 roll on the surface of the grinding belt 66. With the setting of the pressure block assembly 68, when the grinding belt 66 is pressed down to grind the edge of the anti-falling net body 2, the rollers 684 will roll on the surface of the grinding belt 66, thereby reducing the resistance between the grinding belt 66 and the pressure block assembly 68. Moreover, by utilizing the elastic force of the elastic telescopic rods 683, the welding marks on the surface of the anti-falling net body 2 can be gradually ground.

[0029] The lifting platform 3 is driven by a tight screw to achieve precise positioning. It can be equipped with a PLC controller or photoelectric sensor to achieve automatic rising and falling and automatic sensing action. It is convenient and simple to operate. At the same time, a clamp can be installed on the top of the lifting platform 3 to limit and lock the anti-falling net body 2. Baffles are installed around the lifting platform 3 to prevent dust generated during grinding from affecting the service life of the components in the lifting platform 3.

[0030] Telescopic protective covers can also be installed on the surfaces of the guide post 5 and the ball screw 7 to reduce dust during grinding and improve their service life.

[0031] Working principle: When using this utility model, the user places the anti-falling net bodies 2 one by one on the top of the lifting platform 3. The lifting platform 3 then moves the anti-falling net bodies 2 up and down, bringing the topmost anti-falling net body 2 close to the bottom of the pressure block assembly 68. Subsequently, the motor at the bottom of the mounting base 61 drives the drive wheel 62 to rotate, thereby driving the grinding belt 66. The cylinder 67 then moves the pressure block assembly 68 downward, causing the grinding belt 66 to deform and contact the welded joints of the anti-falling net bodies 2, thus grinding the anti-falling net bodies 2. During the polishing process of 2, the user can manually push the lifting platform 3 to move the anti-falling net body 2, and the motor 8 drives the ball screw 7 to rotate, thereby causing the polishing component 6 to slide left and right on the surface of the guide column 5, so as to achieve full polishing of the anti-falling net body 2. After the top anti-falling net body 2 is polished, the lifting platform 3 drives the anti-falling net body 2 to rise, so as to achieve polishing of the second layer of anti-falling net body 2. It should be noted that the polishing device of this application is mainly for polishing the weld seam of the frame of the rectangular anti-falling net body 2.

[0032] All standard parts used in this invention can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through the control unit. The control circuit of the control unit can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. Therefore, the control method and circuit connection will not be explained in detail in this invention.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
