Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure processing technology, and in particular to a steel structure grinding device. Background Technology
[0002] Grinding is an important process in steel structure processing. Its purpose is to remove impurities such as oxide scale, rust, and welding slag from the surface of the steel structure to ensure the surface quality of the steel structure and improve the quality and effect of subsequent painting, welding and other processes. Grinding generates a lot of dust, which not only pollutes the working environment but also endangers the health of the operators.
[0003] A search revealed Chinese patent documents (authorization announcement number CN215788973U), indicating that this utility model relates to the field of steel structure technology and discloses a steel structure grinding device. This device includes a base plate, a working plate fixedly connected to the upper surface of the base plate, a support plate fixedly connected to the upper surface of the base plate, a conveyor belt disposed between the working plate and the support plate, the conveyor belt being disposed on the upper surface of the base plate, and a motor chamber formed inside the working plate, with a servo motor disposed inside the motor chamber. This steel structure grinding device works by rotating a handle mounted on a worm gear, which in turn drives a worm wheel to rotate a threaded rod. The threaded rod then causes a threaded block to slide on a slide bar. The threaded block, via a connecting shaft, moves a pressure roller, facilitating adjustment of the gap between the pressure roller and the conveyor belt. This allows for grinding of different types of steel structures. Small rollers mounted on the upper support plate engage with the grinding belt to maintain belt tension and ensure normal operation. While the device meets basic usage requirements, it generates a large amount of dust during grinding, which not only pollutes the working environment but also harms the health of operators. Utility Model Content
[0004] The purpose of this invention is to provide a steel structure grinding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure grinding device, comprising a support frame for supporting the steel structure, wherein a collection rack is installed on the side of the support frame;
[0006] The collection rack has a double-circular cross groove for limiting positioning inside. Two springs are installed inside the double-circular cross groove, and the ends of the two springs are connected to a double-circular cross plate. The double-circular cross plate is slidably disposed inside the double-circular cross groove. A position sensor is installed at the bottom of the double-circular cross plate, and a position detector that cooperates with the position sensor is installed on the inner bottom wall of the double-circular cross groove. A collection box for collecting metal scraps is slidably installed on the top of the double-circular cross plate.
[0007] Preferably, a filter box for dust filtration is installed on the top of the collection rack, and a dust inlet is provided at the bottom of the filter box for dust to enter. Two filter plate frames for support are slidably installed inside the filter box.
[0008] Preferably, both filter plate frames are equipped with filter plates for filtering dust, and the top of the filter box is provided with an air outlet for the filtered gas to be discharged, and a fan is installed inside the air outlet.
[0009] Preferably, a grinding table is installed on the top of the collection rack to limit the displacement of the steel structure, and a baffle is welded to the side of the grinding table to prevent grinding debris from splashing out.
[0010] Preferably, the bottom of the grinding table is provided with a chip inlet groove for grinding chips to enter, the bottom of the grinding table is connected to a collection hopper, and the bottom of the collection hopper is connected to a waste chip pipe.
[0011] Preferably, a first drive unit is mounted on the side of the support frame, a first connecting part is mounted on the movable part of the first drive unit, and a grinding disc for grinding the steel structure is mounted on the movable part of the first connecting part.
[0012] Preferably, a second drive unit is installed inside the support frame, the movable part of the second drive unit is connected to a second connecting part, and the movable part of the second connecting part is equipped with a moving platform for vertical movement.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] This steel structure grinding device, thanks to the structure of the filter box, allows metal shavings and dust generated during grinding to enter the collection hopper and waste shavings pipe through the shavings inlet. The metal shavings enter the collection box, while the dust enters the filter box through the dust inlet and comes into contact with the filter plate. The filter plate filters the dust, and the filtered gas is discharged through the air outlet. Compared with traditional steel structure grinding devices, which have a weak ability to handle the large amount of dust generated during grinding, this structure can improve filtration efficiency, reduce dust and smoke pollution to the working environment, and protect the health of operators.
[0015] This steel structure grinding device benefits from the structure of the collection box. As the metal shavings inside the collection box increase, the collection box presses down on the double circular cross plate and the position sensor. The position sensor and the position detector work together to determine the position of the collection box, thereby determining whether the collection box needs to be removed for cleaning, reducing frequent shutdowns for cleaning and improving processing efficiency.

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0026] like Figures 1 to 5The steel structure grinding device shown includes a support frame 1 for supporting the steel structure, and a collection rack 107 is installed on the side of the support frame 1.
[0027] The collection rack 107 has a double-circular cross groove 3 for limiting movement inside. Two springs 301 are installed inside the double-circular cross groove 3. Damping is provided between the two springs 301 and the double-circular cross groove 3. The ends of the two springs 301 are connected to a double-circular cross plate 304. The double-circular cross plate 304 is slidably disposed inside the double-circular cross groove 3. A position sensor 303 is installed at the bottom of the double-circular cross plate 304. A position detector 302 that cooperates with the position sensor 303 is installed on the inner bottom wall of the double-circular cross groove 3. A collection box 305 for collecting metal shavings is slidably installed on the top of the double-circular cross plate 304. After a period of time, the metal shavings in the collection box 305 increase. The collection box 305 presses down on the double-circular cross plate 304 and the position sensor 303. The control system of the device is connected to the position sensor 303 and the position detector 302 and continuously receives the signal data generated by their interaction. The control system has a preset signal characteristic range for the collection box 305 when it is in its normal position. When the actual received signal exceeds this range, the control system determines that the position of the collection box 305 is abnormal. In addition, by setting a weight threshold, when dust accumulates in the collection box 305 and the weight increases, causing a slight change in position, the sensor 303 detects the signal change. After analysis and judgment by the control system, when the preset threshold is reached, it prompts that the collection box 305 needs to be removed for cleaning, reducing frequent shutdowns for cleaning and improving processing efficiency.
[0028] A filter box 4 for dust filtration is installed on the top of the collection rack 107. A dust inlet 401 for dust to enter is provided at the bottom of the filter box 4. Two filter plate frames 402 for support are slidably installed inside the filter box 4. Filter plates 403 for dust filtration are installed inside the two filter plate frames 402. An air outlet 404 for the exhaust of filtered gas is provided on the top of the filter box 4. A fan 405 is installed inside the air outlet 404. When the fan 405 is turned on, the metal shavings and dust generated during grinding enter the collection hopper 203 and waste shavings pipe 204 through the chip inlet 202. The metal shavings enter the collection box 305, and the dust enters the filter box 4 through the dust inlet 401 and comes into contact with the filter plates 403. The filter plates 403 filter the dust, and the filtered gas is discharged through the air outlet 404.
[0029] The top of the collection rack 107 is equipped with a grinding table 2 for limiting the displacement of the steel structure. The side of the grinding table 2 is welded with a baffle 201 for preventing grinding chips from splashing out. The bottom of the grinding table 2 is provided with a chip inlet 202 for grinding chips to enter. The bottom of the grinding table 2 is connected to a collection hopper 203, and the bottom of the collection hopper 203 is connected to a waste chip pipe 204. The sparks generated during grinding are blocked by the baffle 201 to prevent metal waste chips from splashing out.
[0030] A first drive unit 101 is mounted on the side of the support frame 1. The first drive unit 101 uses a grinding motor as the power core of the grinding mechanism. The output shaft drives the grinding disc 103 to rotate at high speed. Relying on the strong rotational power, it efficiently grinds away impurities such as oxide scale and rust from the steel structure surface. A first connecting part 102 is mounted on the movable part of the first drive unit 101. The grinding disc 103 for grinding the steel structure is mounted on the movable part of the first connecting part 102. The grinding disc 103 is fixedly connected to the output shaft of the grinding motor and rotates at high speed under the drive of the grinding motor. It uses the abrasive on its surface to contact and rub against the steel structure surface, thereby removing impurities such as oxide scale, rust, and welding slag. It is mounted on a movable crossbeam via an adjustable bracket, allowing for angle adjustment in both horizontal and vertical directions. This enables flexible adaptation to steel structure surfaces of different shapes and angles. Combined with the lifting and horizontal movement of the movable crossbeam, it achieves comprehensive grinding of all parts of the steel structure, effectively improving grinding efficiency and quality. Furthermore, different grinding discs 103 of different materials and grit sizes can be replaced according to different grinding needs to meet diverse grinding precision requirements. A second drive unit 104 is installed inside the support frame 1. The second drive unit 104 consists of a drive motor and a lead screw transmission mechanism forming a lifting power source. The motor drives the lead screw to rotate, and through the cooperation of the nut and the lead screw, the rotational motion is converted into the vertical linear motion of the moving crossbeam along the column, thus adapting to the grinding needs of steel structures of different heights. The movable part of the second drive unit 104 is connected to a second connecting part 105. The movable part of the second connecting part 105 is equipped with a moving table 106 for vertical movement. When the steel structure material is placed in the grinding table 2, the second drive unit 104 is activated. The second drive unit 104 drives the second connecting part 105 to adjust the height of the moving table 106, thereby adjusting the height of the first connecting part 102 and the grinding disc 103. The first drive unit 101 is then activated, driving the first connecting part 102 and the grinding disc 103 to rotate, and the grinding disc 103 grinds the steel structure material.
[0031] Working principle
[0032] In use, the steel structure grinding device first places the steel structure material into the grinding table 2, then activates the second drive unit 104. The second drive unit 104 drives the second connecting part 105 to adjust the height of the moving table 106, thereby adjusting the height of the first connecting part 102 and the grinding disc 103. Then, the first drive unit 101 is activated, causing the first connecting part 102 and the grinding disc 103 to rotate. The grinding disc 103 grinds the steel structure material. Sparks generated during grinding are blocked by the baffle 201 to prevent metal shavings from splashing out. The fan 405 is then activated, and the metal shavings and dust generated during grinding pass through the chip inlet 2. 02. Metal shavings enter the collection hopper 203 and waste pipe 204, and enter the collection box 305. Dust enters the filter box 4 through the dust inlet 401 and comes into contact with the filter plate 403. The filter plate 403 filters the dust, and the filtered gas is discharged through the air outlet 404. After a period of time, the metal shavings in the collection box 305 increase. The collection box 305 presses down the double circular cross plate 304 and the position sensor 303. The position sensor 303 and the position detector 302 work together to determine the position of the collection box 305, thereby determining whether the collection box 305 needs to be removed for cleaning, reducing frequent shutdowns for cleaning and improving processing efficiency.
