Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a steel structure grinding device that facilitates the collection of debris. Background Technology

[0002] During construction, it is generally necessary to grind the protruding burrs on the surface of the steel structure. The common method is to grind by hand and wash with water during the grinding process to cool the steel structure and wash away the waste. However, the grinding waste is washed to the ground or other places by the water flow, which is not only difficult to clean, but also cannot be collected, resulting in waste of steel. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a steel structure grinding device that facilitates the collection of debris during the grinding process.

[0004] The technical solution adopted in this invention is:

[0005] A steel structure grinding device for easy collection of debris includes an outer cover assembly, a grinding assembly, and a collection assembly. The grinding assembly and the collection assembly are both disposed inside the outer cover assembly. The outer cover assembly includes an end plate and shields disposed on the upper and lower sides of the end plate. A collection hood is disposed inside the lower shield. The grinding assembly includes a grinding disc and a drive motor for driving the grinding disc to rotate. The collection assembly includes two sets of rotating scrapers. The grinding disc and the two sets of rotating scrapers are rotatably mounted on the end plate, and the two sets of rotating scrapers are respectively disposed on both sides of the grinding disc. During the grinding process, the drive motor synchronously drives the grinding disc and the two sets of rotating scrapers to rotate, scraping off the debris and causing it to fall into the collection hood.

[0006] As a further optimization, the drive motor of the present invention is connected to the grinding disc via a drive shaft, and a transmission shaft extending toward the rotating scraper is rotatably provided on the end plate. One end of the transmission shaft is connected to the drive shaft via a first bevel gear structure, and the other end of the transmission shaft is connected to the rotating scraper via a second bevel gear structure.

[0007] As a further optimization, the rotating scraper of the present invention is connected to the transmission shaft via a bevel gear structure through a connecting shaft, and the rotating scraper is slidably connected to the connecting shaft. The sliding direction of the rotating scraper is along the axial direction of the connecting shaft, and a first spring is provided between the rotating scraper and the connecting shaft. When the rotating scraper moves toward the connecting shaft, the first spring is in a compressed state.

[0008] As a further optimization, the shield and the end plate of the present invention are slidably connected. A guide shaft is provided on the rear side of the shield and a guide sleeve is provided on the back of the end plate. The guide shaft on the shield is slidably connected to the guide sleeve on the end plate, and a second spring is provided between the guide shaft and the guide sleeve. When the two shields move away from each other, the second spring is in a stretched state.

[0009] As a further optimization, the shielding cover of the present invention is provided with a shielding assembly, which includes two support rods and a flexible shielding member disposed between the two support rods. The edge of the shielding cover is provided with a square groove and a hole groove. A sleeve is slidably disposed in the square groove of the shielding cover. The sliding direction of the sleeve is perpendicular to the end plate, and a third spring is disposed between the sleeve and the square groove. When the sleeve moves towards the end plate, the third spring is in a compressed state. One of the support rods of the shielding assembly is connected to the hole groove, and the other support rod is slidably connected to the sleeve. When approaching the steel structure, the steel structure first contacts the outer support rod and further pushes the support rod, causing the flexible shielding member to curl naturally until the steel structure contacts the grinding disc.

[0010] As a further optimization, the end plate of the present invention is provided with two sets of anti-fall components on the upper and lower sides. Each set of anti-fall components includes a U-shaped rod and a sliding groove on the back of the end plate. The end of the U-shaped rod protrudes from the shield, and the bottom of the U-shaped rod is slidably disposed in the sliding groove of the end plate in the vertical direction. A fourth spring is also provided between the U-shaped rod and the sliding groove. When the two sets of U-shaped rods move away from each other, the fourth spring is in a compressed state.

[0011] As a further optimization, the collecting cover limiting rod of the present invention has a limiting groove at its end. The limiting rod passes through the end plate. When the U-shaped rod located on the lower side moves downward, the bottom rod of the U-shaped rod is in a state of moving into the limiting groove.

[0012] As a further optimization, the present invention also provides a water spraying component inside the shielding cover on the upper side. The water spraying component includes a water pipe and a water storage tank. The bottom of the water storage tank is provided with a drip hole. Both the collection cover and the shielding cover on the lower side are provided with water permeable holes.

[0013] As a further optimization, the back of the end plate of the present invention is also provided with a hand-held assembly. The hand-held assembly includes a grip handle and a connector fixedly disposed on the back of the end plate. The connector is a ball. One end of the grip handle is a connecting ring that matches the connector. The connecting ring is sleeved on the ball and connected by a pin.

[0014] As a further optimization, the collection cover of the present invention is an embedded structure that matches the shielding cover, and the longitudinal interface of the collection cover is a U-shaped structure.

[0015] The present invention has the following advantages:

[0016] 1. The grinding device of the present invention drives the grinding disc and the rotating scraper to rotate through the same power structure, which facilitates the scraping of waste adsorbed on the surface of the steel structure, especially when wet, the effect is obvious.

[0017] 2. The grinding device of the present invention has a shielding component between two adjustable shields to block the gap between the two shields and prevent waste from flying out from the gap. Moreover, the shielding component has the self-adjusting ability to adapt the width and length to the size of the steel structure, making it more convenient to use.

[0018] 3. The U-shaped rod in the anti-fall assembly of the present invention can move up and down, leaving adjustment space for the grinding process and preventing the grinding device from falling off due to slipping. Attached Figure Description

In the embodiments of the present invention, "multiple" refers to two or more.

[0035] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, B existing alone, or both A and B existing simultaneously. Furthermore, in this document, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0036] This embodiment provides a steel structure grinding device 1 that facilitates the collection of debris. Specifically, as shown in the example... Figure 1 The diagram shows an outer cover assembly, a polishing assembly 13, and a collection assembly. The polishing assembly 13 and the collection assembly are both housed within the outer cover assembly. The outer cover assembly includes an end plate 12 and shielding covers 15 disposed on the upper and lower sides of the end plate 12. A collection cover 18 is disposed within the lower shielding cover 15. Figure 10As shown, the collection cover 18 is an embedded structure that matches the shield 15, and the longitudinal interface of the collection cover 18 is a U-shaped structure. A handheld assembly is also provided on the back of the end plate 12. The handheld assembly includes a grip handle 111 and a connector fixedly disposed on the back of the end plate 12. The connector is a sphere, such as... Figure 2 As shown, one end of the grip 111 is a connecting ring 112 that matches the connecting body. The connecting ring 112 is sleeved on the ball, and the connecting ring 112 is provided with a corresponding connecting port 113. The connecting ring 112 and the connecting body are connected by a pin 123. The grinding assembly includes a grinding disc 133 and a drive motor 131 for driving the grinding disc 133 to rotate. Specifically, it can be configured as follows: Figure 4 The structure shown includes a groove 121 within the connecting body for housing the drive motor 131. The drive motor 131 is housed within the groove 121. The collecting assembly includes two sets of rotating scrapers 141. The grinding disc 133 and the two sets of rotating scrapers 141 are rotatably mounted on the end plate 12, with the two sets of rotating scrapers 141 respectively positioned on the upper and lower sides of the grinding disc 133. The drive motor 131 is connected to the grinding disc 133 via a drive shaft 132. A drive shaft 132 is rotatably mounted on the end plate 12 to guide the rotating scrapers 131. 41. An extended drive shaft 134 is rotatably mounted on an end plate 12 via a bearing 122. One end of the drive shaft 134 is connected to a drive shaft 132 via a first bevel gear structure, and the other end is connected to a rotating scraper 141 via a second bevel gear structure. The rotating scraper 141 is connected to the drive shaft 134 via a connecting shaft 14 through a bevel gear structure, and the rotating scraper 141 is slidably connected to the connecting shaft 14. Specifically, as shown... Figure 5 As shown, a spline block 143 is provided at the end of the connecting shaft 14, and a spline groove 142 is provided in the middle of the rotating scraper 141. The sliding direction of the rotating scraper 141 is along the axial direction of the connecting shaft 14, and a first spring is provided between the rotating scraper 141 and the connecting shaft 14. When the rotating scraper 141 moves toward the connecting shaft 14, the first spring is in a compressed state.

[0037] like Figure 6 As shown, in this embodiment, the shield 15 and the end plate 12 are slidably connected. A guide shaft 151 is provided on the rear side of the shield 15, and a guide sleeve 124 is provided on the back of the end plate 12. The guide shaft 151 on the shield 15 and the guide sleeve on the end plate 12 are slidably connected, and a second spring 152 is provided between the guide shaft 151 and the guide sleeve. When the two shields 15 move away from each other, the second spring 152 is in a stretched state. The shield 15 is set to a slidable state, that is, the distance between the two shields 15 can be adjusted to adapt to steel structures of different sizes.

[0038] Since the spacing between the two shields 15 is adjustable, a space needs to be provided between the two shields 15 to accommodate this setting and prevent debris from flying out from the gap between the two shields 15. Figure 7 As shown, a shielding assembly is provided between the shielding covers 15. The shielding assembly 16 includes two support rods 162 and a flexible shielding member disposed between the two support rods 162. The edge of the shielding cover 15 is provided with a square groove 153 and a hole groove. A sleeve 161 is slidably disposed in the square groove 153 of the shielding cover. The sliding direction of the sleeve 161 is perpendicular to the end plate 12, and a third spring is provided between the sleeve 161 and the square groove 153. When the sleeve 161 moves towards the end plate 12, the third spring is in a compressed state. One of the support rods 162 of the shielding assembly is slidably connected to the hole groove, and the other support rod 162 is slidably connected to the sleeve 161. When approaching the steel structure 2, the steel structure 2 first contacts the outer support rod 162 and further pushes the support rod 162, causing the flexible shielding member to curl naturally until the steel structure 2 contacts the grinding disc 133.

[0039] like Figure 8 As shown, two sets of anti-fall components are provided on the upper and lower sides of the end plate 12. Each set of anti-fall components includes a U-shaped rod 126 and a sliding groove 125 on the back of the end plate 12. The end of the U-shaped rod 126 protrudes from the shield 15, and the bottom of the U-shaped rod 126 is slidably disposed in the sliding groove 125 of the end plate 12 in the vertical direction. A fourth spring is also provided between the U-shaped rod 126 and the sliding groove 125. When the two sets of U-shaped rods 126 move away from each other, the fourth spring is in a compressed state. The two sets of U-shaped rods 126 slide up and down, which can leave grinding space to accommodate steel structures of different sizes. In the event that the grinding device 1 falls off due to slippage, the U-shaped rods 126 can still support the steel structure 2, preventing the grinding device 1 from falling off. To further enhance the anti-fall effect, the end of the U-shaped rod 126 can be designed as a hook.

[0040] like Figure 10 As shown, a limiting rod 181 is provided at the rear end of the collection cover 18, and a limiting groove is provided at the end of the limiting rod 181. The limiting rod 181 passes through the end plate 12. When the U-shaped rod 126 located on the lower side moves downward, the bottom of the U-shaped rod 126 is in a state of moving into the limiting groove. The collection cover 18 is embedded in the shielding cover. Since the vibration during the grinding process is relatively large, the embedding method alone is not secure. By setting the limiting groove and the U-shaped rod 126 engaging, the limiting function can be achieved.

[0041] like Figure 9As shown, a water spraying assembly 17 is also provided inside the shield 15 located on the upper side. The water spraying assembly 17 includes a water pipe 171 and a water storage tank. A drip hole is provided at the bottom of the water storage tank. In order to avoid water flowing out too quickly and to achieve a dripping effect, the size of the drip hole is set relatively small. The drip hole can play a role in adsorbing the waste debris and causing it to fall into the collection hood 18. Correspondingly, both the collection hood 18 and the shield 15 located on the lower side are provided with water permeable holes 182 to filter the moisture in the waste debris and retain only the waste debris.

[0042] like Figure 11 The diagram shown is a schematic of the steel structure grinding process in this embodiment. The steel structure 2 can be an I-beam, square steel, etc. When grinding the steel structure, the position is adjusted up and down so that the steel structure 2 is inserted between the upper and lower shields 15, the two shields 15 are opened, and the shielding component 16 is pushed inward until it contacts the grinding disc 13. At the same time, the two sets of U-shaped rods 126 are also opened and supported on the upper and lower ends of the steel structure 2. After the drive motor 131 is started, the grinding disc 13 and the rotating scraper 141 start simultaneously. After grinding the waste, the rotating scraper 141 scrapes off the waste adhering to the steel structure 2 and it falls into the collection cover 18. Finally, after grinding is completed, the waste is recycled and processed in a unified manner.

[0043] The above-described embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention. The scope of protection of the present invention is defined by the claims.
