Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a steel structure grinding equipment with negative pressure dust removal capability. Background Technology

[0002] Steel structures are a widely used structural form in construction. Due to their low steel consumption, fast construction speed, and high economic benefits, they are gradually becoming a green building material. Currently, the design and construction technology of steel structures is basically mature and they have been widely used in industrial plants, highways and railways, warehouses, garages, shopping malls, stadiums, airports, and commercial buildings.

[0003] Grinding is an indispensable step in the fabrication of steel structures. Grinding removes impurities such as rust, scale, and burrs from the steel structure surface, improving its surface quality and ensuring the smooth progress of subsequent painting and welding processes. However, grinding steel structures generates a large amount of metal dust. This dust not only permeates the working environment, severely polluting the air and posing a significant threat to the respiratory system of operators—long-term inhalation may lead to serious diseases such as pneumoconiosis—but also poses a certain explosion risk if it accumulates in large quantities in the workshop, threatening production safety.

[0004] Some existing patents have addressed the dust problem to some extent. For example, patent publication number CN214771160U describes a steel structure grinding device, which belongs to the field of steel structure engineering technology. The grinding device is a trolley structure for easy movement. It has two side plates located on the left and right sides of the operating table. During the grinding process, sparks are mostly scattered to the sides, and the side plates can block the sparks. An operating table is set on the base of the grinding device, and a telescopic shaft is set between the operating table and the base. The operating table consists of an outer frame and an inner plate. The telescopic shaft is connected to the inner plate. The steel structure material to be ground is placed on the inner plate and the grinding position is adjusted. The telescopic shaft raises the inner plate to contact the grinding disc for grinding. The debris generated during the grinding process is blocked by the side plates. After grinding, a suction pipe can be installed to suck away the residual debris on the operating table and base, keeping the operating table surface clean. However, dust extraction via suction pipes is performed after grinding, and the dust generated during grinding spreads and affects the working environment. Furthermore, manual adjustment of the suction port is required for dust removal, resulting in high manual intervention and low automation efficiency. Additionally, the waste debris generated during steel structure grinding is at a certain temperature; these warm impurities entering the suction equipment can disrupt its normal operation. Therefore, there is an urgent need to design steel structure grinding equipment with negative pressure dust removal capability to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a steel structure grinding device capable of negative pressure dust removal, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] Steel structure grinding equipment with negative pressure dust removal capability includes:

[0008] The chassis has a three-jaw positioning chuck installed at the top center.

[0009] A grinding assembly is disposed on top of the three-jaw positioning chuck, and a movable module for adjusting the position of the grinding assembly is provided on the chassis;

[0010] The negative pressure dust removal assembly includes a cyclone dust collector installed at the center of the bottom of the chassis. A second guide pipe extending out of the chassis is installed at the air inlet end of the cyclone dust collector. A corrugated pipe is installed at the top of the second guide pipe, and a first guide pipe is installed at the top of the corrugated pipe. An annular suction hood is installed at one end of the first guide pipe. A first air guide pipe is installed at the top exhaust end of the cyclone dust collector. A negative pressure generating device is installed at one end of the first air guide pipe and on one side of the inner wall of the chassis. A second air guide pipe is installed at the exhaust end of the negative pressure generating device. A cooling assembly is installed on one side of the chassis.

[0011] Furthermore, the mobile module includes a first support frame installed on one side of the top of the chassis, and an X-axis mobile module is installed on the top of the first support frame, and a Z-axis mobile module is installed on the moving end of the X-axis mobile module.

[0012] Furthermore, the polishing assembly includes a polishing box installed at the moving end of the Z-axis moving module, and a polishing motor is installed inside the polishing box, with a polishing disc installed on the output shaft of the polishing motor.

[0013] Furthermore, the annular suction cover is wrapped around the outside of the grinding disc, and the top of the annular suction cover and the bottom of the grinding box are equipped with equally spaced reinforcing rods, and the bottom of the annular suction cover is provided with equally spaced suction holes.

[0014] Furthermore, the cooling assembly includes a cooling cylinder installed at the corner of the second feed pipe, and an exhaust pipe is fixed to the top of one side of the cooling cylinder. A second support is installed on one side of the chassis, and a chilled water circulator is installed on the top of the second support. A spiral circulation pipe inserted into the cooling cylinder is installed on one side of the chilled water circulator, and the spiral circulation pipe is sleeved on the second feed pipe.

[0015] Furthermore, the chassis is equipped with control equipment, which is electrically connected to the negative pressure generating device, the Z-axis moving module, the X-axis moving module, the chilled water circulator, and the grinding motor.

[0016] Furthermore, support legs are installed at the four corners of the bottom of the chassis, and the ash discharge pipe of the cyclone dust collector extends to the bottom of the chassis.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, a three-jaw positioning chuck can be used to quickly position and clamp the steel structure, which facilitates grinding operations. Since both the X-axis moving module and the Z-axis moving module are moving structures driven by motor screws, the position of the grinding components can be precisely adjusted to achieve precise grinding of different parts of the steel structure, thereby improving grinding efficiency and quality.

[0019] In this invention, the coordinated use of components such as an annular suction hood, a first guide pipe, a corrugated pipe, a second guide pipe, and a cyclone dust collector allows for timely extraction of dust generated during the grinding process, replacing manual operation. The cyclone dust collector efficiently separates the dust-laden gas, collecting the dust in the ash discharge pipe. The purified gas then enters the negative pressure generating device through the first guide pipe and is discharged through the second guide pipe. This achieves effective separation of dust and gas, facilitating centralized dust treatment and preventing dust from entering and damaging the negative pressure generating device. Furthermore, the annular suction hood, which surrounds the grinding disc, has suction holes at its bottom that effectively and quickly collect dust, preventing it from spreading into the air, improving the working environment, and protecting the health of operators.

[0020] In this invention, the cooling water circulator in the cooling component cools the second feed pipe through a spiral circulation pipe, which can effectively reduce the dust temperature and avoid safety hazards caused by high temperature. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figures 1-5 In this embodiment of the invention, the steel structure grinding equipment capable of negative pressure dust removal includes:

[0029] The chassis 1 has a three-jaw positioning chuck 2 installed at the top center. The three-jaw positioning chuck 2 can be used to quickly position and clamp the steel structure, which is convenient for grinding operations.

[0030] The grinding assembly is located on top of the three-jaw positioning chuck 2. The housing 1 is equipped with a moving module for adjusting the position of the grinding assembly. The moving module includes a first support 7 installed on one side of the top of the housing 1, and an X-axis moving module 6 is installed on the top of the first support 7. A Z-axis moving module 5 is installed at the moving end of the X-axis moving module 6. Both the Z-axis moving module 5 and the X-axis moving module 6 are moving structures driven by motor-driven screws. The grinding assembly includes a grinding box 4 installed at the moving end of the Z-axis moving module 5, and a grinding motor 12 is installed inside the grinding box 4. A grinding disc 13 is installed on the output shaft of the grinding motor 12. The position of the grinding assembly can be precisely adjusted to achieve precise grinding of different parts of the steel structure, thereby improving grinding efficiency and quality.

[0031] The negative pressure dust removal assembly 3 includes a cyclone dust collector 307 installed at the center of the bottom of the casing 1. A second guide pipe 310 extending out of the casing 1 is installed at the air inlet end of the cyclone dust collector 307. A corrugated pipe 304 is installed at the top of the second guide pipe 310, and a first guide pipe 303 is installed at the top of the corrugated pipe 304. An annular suction hood 301 is installed at one end of the first guide pipe 303. The annular suction hood 301 surrounds the grinding disc 13. Reinforcing rods 302 are evenly distributed at the top of the annular suction hood 301 and the bottom of the grinding box 4. Equally spaced reinforcing rods 302 are installed at the bottom of the annular suction hood 301. The cyclone dust collector 307 has a first air guide pipe 311 installed at the top exhaust end of the distributed suction holes 312. One end of the first air guide pipe 311 is connected to a negative pressure generating device 308 installed on the inner wall of one side of the casing 1. The negative pressure generating device 308 can be a vacuum pump or a negative pressure fan. The exhaust end of the negative pressure generating device 308 is connected to a second air guide pipe 309. A cooling component is installed on one side of the casing 1. When the negative pressure generating device 308 is activated, a negative pressure environment is formed in the entire negative pressure dust collection component 3, which effectively and quickly collects dust, prevents dust from spreading into the air, improves the working environment, and protects the health of operators.

[0032] Specifically, the cooling component includes a cooling cylinder 306 installed at the corner of the second feed pipe 310, and an exhaust pipe 305 fixed to the top of one side of the cooling cylinder 306. A second support frame 9 is installed on one side of the casing 1, and a chilled water circulator 8 is installed on the top of the second support frame 9. A spiral circulation pipe 14 inserted into the cooling cylinder 306 is installed on one side of the chilled water circulator 8. The spiral circulation pipe 14 is sleeved on the second feed pipe 310. The chilled water circulates in the spiral circulation pipe 14 through the chilled water circulator 8, effectively absorbing the heat of dust and airflow in the second feed pipe 310, achieving a cooling effect and avoiding safety problems caused by high temperature.

[0033] Specifically, a control device 10 is installed inside the chassis 1, and the control device 10 is electrically connected to the negative pressure generating device 308, the Z-axis moving module 5, the X-axis moving module 6, the chilled water circulating machine 8, and the grinding motor 12. The control device 10 enables precise control of each component.

[0034] Specifically, support legs 11 are installed at the four corners of the bottom of the chassis 1, and the ash discharge pipe of the cyclone dust collector 307 extends to the bottom of the chassis 1 to facilitate support for the entire equipment.

[0035] The working principle of this utility model is as follows: the steel structure to be polished is placed on the three-jaw positioning chuck 2, the three-jaw positioning chuck 2 is used to quickly position and clamp the steel structure, the polishing motor 12 is started to drive the polishing disc 13 to rotate at high speed to polish the surface of the steel structure, and the X-axis moving module 6 and Z-axis moving module 5 are controlled by the control device 10 to drive the polishing box 4 and the polishing disc 13 to move in the horizontal and vertical directions, so as to achieve precise polishing of different parts of the steel structure;

[0036] During the grinding process, the negative pressure generating device 308 is activated to create a negative pressure environment within the entire negative pressure dust removal assembly 3. The annular suction hood 301 covers the outside of the grinding disc 13, and the suction hole 312 at its bottom sucks in the dust generated during the grinding process. The dust enters the cyclone dust collector 307 through the first guide pipe 303, the corrugated pipe 304, and the second guide pipe 310 in sequence. Inside the cyclone dust collector 307, the dust-laden airflow rotates, and the dust is separated from the gas by centrifugal force. The dust falls along the inner wall of the cyclone dust collector 307 to the ash discharge pipe and is discharged. The purified gas enters the negative pressure generating device 308 through the first air guide pipe 311, and is then discharged through the second air guide pipe 309, the cooling cylinder 306, and the exhaust pipe 305.

[0037] While grinding, the cold water circulation machine 8 is controlled to run, and the cold water circulates in the spiral circulation pipe 14. Due to the low temperature of the cold water, it can effectively absorb the heat of the dust and airflow in the second guide pipe 310, which has a cooling effect and avoids the safety problems that may be caused by high temperature dust.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
