Description

Technical Field

[0001] This utility model belongs to the field of scaffolding processing technology, specifically relating to a grinding machine for processing the uprights of disc-lock scaffolding. Background Technology

[0002] Disc-lock scaffolding is a new type of socket-type scaffolding. Its components include horizontal bars, vertical bars, diagonal braces, top supports, flat supports, safety ladders, and hook planks. The vertical bars of disc-lock scaffolding are mostly treated with hot-dip galvanizing for corrosion protection. Grinding is a key pretreatment step before coating application. If there is oxide scale, rust, oil stains, or welding residue on the surface of the vertical bars, it will hinder the bonding between the zinc layer and the steel, causing the coating to easily peel off and lift, reducing the anti-corrosion effect. Grinding can remove these impurities, making the surface of the vertical bars uniformly rough, allowing the galvanized layer to adhere tightly, and extending the rust-proof durability of the vertical bars. Therefore, it is necessary to use a grinding machine to grind the vertical bars in disc-lock scaffolding.

[0003] According to the patent announcement number CN223234502U, a disc-lock type scaffolding steel pipe grinding device is known prior art. Although this patent has the advantage of the cleaning cloth being able to remove dust and loose dirt from the surface of the steel pipe to be ground, preventing impurities from being pressed into the surface of the steel pipe by the grinding wheel during the grinding process, causing secondary pollution and affecting the subsequent coating or welding of the steel pipe, the technical solution of this patent still has the following defects in actual use: the steel pipe in this patent requires full manual pushing without any assistance, which is quite laborious. After grinding, the steel pipe will have waste debris attached to it, and the presence of waste debris will affect the adhesion of the subsequent galvanized layer. In addition, the cleaning cloth is directly fixed on the inner wall of the limiting ring block, making the installation and removal of the cleaning cloth inconvenient and slow. Utility Model Content

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a grinding machine for processing uprights of disc-lock scaffolding, including a grinding machine body 1. A feeding conveying assembly 3 is installed at one end of the grinding machine body 1, and a discharging conveying assembly 5 is installed at the other end. The feeding conveying assembly 3 and the discharging conveying assembly 5 have the same structure. The feeding conveying assembly 3 includes two electric push rods 301, which are mounted on the grinding machine body 1. A mounting frame 303 is installed on the movable end of each electric push rod 301. Three rollers 307 are equidistantly arranged on the mounting frame 303, and both ends of the three rollers 307 are connected by bearings. Gears 304 are mounted on the rotating shaft. Three gears 304 on the same side form a group, and there are two groups in total. Both groups of gears 304 are connected by a gear chain 306. A first motor 305 is mounted on one side of the mounting frame 303 via a fixed seat. The output shaft of the first motor 305 is fixed to a gear 304 via a coupling. This gear 304 is located in the middle of a group of gears 304. An inclined groove 302 is provided on the inner wall of the mounting frame 303. The inclined groove 302 allows waste or impurities to be discharged from the mounting frame 303. A support limit frame 4 is provided on one side of the feeding conveying component 3. In this embodiment, the upright of the disc-lock scaffold to be ground is first placed on the support limit frame 4, and the first motor 305 on the feeding conveying assembly 3 is started, so that the first motor 305 drives the gear 304 to rotate. Under the transmission action of the toothed chain 306, the three rollers 307 can rotate in the same direction. In this way, before the upright is inserted into the feeding cleaning assembly 6 and before the grinding wheel 9 starts grinding, the operation of the feeding conveying assembly 3 provides assistance for the conveying of the upright, so that the upright does not need to be pushed forward by manpower, saving the physical strength of the workers. After the grinding wheel 9 finishes grinding the uprights and the uprights are cleaned by the discharge cleaning component 7, the discharge conveying component 5 can continue to convey the ground uprights for a period of time to prevent them from falling directly off the grinding machine body 1 after grinding, making it easier for the staff to take away the ground uprights.

[0018] In the above scheme, it should be noted that: the support limit frame 4 is a structure that can be vertically telescopically adjusted, consisting of two movably connected support rods and bolts, that is, the two support rods are locked together by bolts, and the bottom of the support limit frame 4 bottom support rod is fixed to the grinding machine body 1, and the top of the support limit frame 4 top support rod is connected to an arc-shaped support block, such as the existing tripod telescopic fixing rod, which is existing technology and will not be described in detail here.

[0019] Please see Figure 1 , Figure 2 and Figure 3 The grinding machine body 1 is provided with an adjustment component 8, on which a first movable seat 14 and a second movable seat 11 are installed. A second motor 13 and a third motor 10 are respectively installed on the first movable seat 14 and the second movable seat 11. Guide wheels 12 and grinding wheels 9 are respectively installed on the output shafts of the second motor 13 and the third motor 10 through couplings. The adjustment component 8 includes a movable groove 805 and a bidirectional threaded rod 802. The movable groove 805 is opened on the grinding machine body 1. The pulleys at the bottom of the first movable seat 14 and the second movable seat 11 are slidably connected in the movable groove 805. Both ends of the bidirectional threaded rod 802 are installed on the shield 2 through bearings and rotating shafts. A rotating wheel 801 is installed at one end of one rotating shaft. A first threaded block 803 and a second threaded block 804 are threadedly connected to the bidirectional threaded rod 802. The first threaded block 803 and the second threaded block 804 are welded and fixed to the first movable seat 14 and the second movable seat 11, respectively.

[0020] In this embodiment, the heights of the support limiting frame 4, the feeding conveying assembly 3, the discharging conveying assembly 5, the feeding cleaning assembly 6, and the discharging cleaning assembly 7 can be adjusted in advance according to the diameter of the disc-lock scaffold uprights so that their center points are in a straight line. Then, the rotating wheel 801 is rotated, and the first threaded block 803 and the second threaded block 804 move closer or further away from each other on the bidirectional threaded rod 802. At the same time, multiple pulleys slide in the movable groove 805 until the guide wheel 12 and the grinding wheel 9 reach the required distance and stop. That is, the guide wheel 12 and the grinding wheel 9 contact the two sides of the upright respectively, thus making it suitable for processing uprights of various diameters. Please see Figure 4 , Figure 5 and Figure 6The adjusting assembly 8 has a feeding cleaning assembly 6 and a discharging cleaning assembly 7 installed on both sides respectively. The feeding cleaning assembly 6 and the discharging cleaning assembly 7 have the same structure. The feeding cleaning assembly 6 includes a support cylinder 606, which is installed on the grinding machine body 1. A support rod 605 is slidably connected inside the support cylinder 606. A groove 607 is opened on the support cylinder 606, and a threaded rod 608 is slidably connected inside the groove 607. One end of the threaded rod 608 is fixed to the outer surface of the support rod 605, and the other end of the threaded rod 608 passes through the groove 607 and is threadedly connected to a threaded cap 609. One side of the cap 609 abuts against the outer surface of the support cylinder 606. The top of the support rod 605 is fixedly connected to the mounting cylinder 601. The cylindrical cleaning cloth 604 is sleeved inside the mounting cylinder 601. The handle of the cylindrical cleaning cloth 604 is provided with a threaded hole. The mounting cylinder 601 is integrally formed with a limit frame 603. The limit frame 603 is threadedly connected with a fixing bolt 602. The handle of the cylindrical cleaning cloth 604 passes through the limit frame 603. The fixing bolt 602 is threadedly connected to the threaded hole. The grinding area of ​​the grinding machine body 1 is provided with a shield 2. The shield 2 can be made of transparent material. In this embodiment, when the electric push rod 301 is started, the height of the roller 307 can be adjusted. By loosening the threaded cap 609 and sliding the threaded rod 608, the height of the mounting cylinder 601 can be adjusted and fixed. When it is necessary to replace the tubular cleaning cloth 604 on the feeding cleaning component 6 and the discharging cleaning component 7, the tubular cleaning cloth 604 can be removed by loosening the fixing bolt 602 and pulling the handle on the tubular cleaning cloth 604. Then, a new tubular cleaning cloth 604 can be installed. The installation and removal are convenient and quick. The discharging cleaning component 7 can clean the upright after grinding, preventing waste from adhering to the upright. In the above solution, it should be noted that the tubular cleaning cloth 604 can be composed of a shell made of rigid materials such as plastic and a cleaning cloth pasted on the inner wall of the shell, which is existing technology. Moreover, the tubular cleaning cloth 604 can be disassembled and replaced according to the diameter of the pole, thereby ensuring that the tubular cleaning cloth 604 and the pole can fit tightly together.

[0021] The working principle and usage process of this utility model are as follows: First, the workers can manually adjust the height of the support limit frame 4 according to the diameter of the upright of the disc-lock scaffold. Then, they can turn the threaded cap 609 and slide the threaded rod 608 to adjust the height of the mounting cylinder 601. At the same time, they can start the electric push rod 301 to adjust the height of the roller 307 and manually rotate the rotating wheel 801 so that the first threaded block 803 and the second threaded block 804 move closer or further apart on the bidirectional threaded rod 802. Meanwhile, multiple pulleys slide in the movable groove 805 until the guide wheel 12 and the grinding wheel 9 can contact the surface of the upright respectively. Next, after the heights of the support limit frame 4, roller 307 and mounting cylinder 601, as well as the distance between the guide wheel 12 and the grinding wheel 9 are adjusted, the workers first place the upright to be ground on the support limit frame 4, so that the end of the upright is located on the feeding conveyor assembly 3. At this time, the first motor 305 is started, so that the first motor 305 drives the gear 304 to rotate. Under the transmission action of the gear chain 306, the three rollers 307 can rotate in the same direction, thereby driving the upright to move. Then, with the manual assistance of the staff, one end of the upright is inserted into the feeding and cleaning component 6, and driven by the feeding and conveying component 3, it continues to move towards the gap between the grinding wheel 9 and the guide wheel 12 in the grinding area. At this time, the second motor 13 and the third motor 10 are started to work, so that the guide wheel 12 and the grinding wheel 9 rotate in the same direction. When the upright comes into contact with the two, the surface of the upright can be rolled and polished. Secondly, when the upright moves toward the discharge cleaning component 7, the polished upright will pass through the discharge cleaning component 7. At this time, the tubular cleaning cloth 604 on it can clean off the attached waste, and the upright is then transported by the discharge conveying component 5, so that the staff can easily take away the polished upright. Finally, when it is necessary to replace the tubular cleaning cloth 604 on the feed cleaning assembly 6 and the discharge cleaning assembly 7, simply loosen the fixing bolt 602 and pull the handle on the tubular cleaning cloth 604 to remove the tubular cleaning cloth 604 and then install a new tubular cleaning cloth 604.

[0022] In the above scheme, it should be noted that: the diameter of the upright in this application cannot be greater than the diameter of the mounting cylinder 601, and the diameter of the upright cannot be less than the minimum distance between the guide wheel 12 and the grinding wheel 9. That is, the grinding machine in this application can only process uprights of various diameters of disc-lock scaffolding, and is not applicable to all disc-lock scaffolding uprights of different diameters. The feeding conveying assembly 3 and the discharging conveying assembly 5 have the same structure and driving method. The feeding cleaning assembly 6 and the discharging cleaning assembly 7 have the same structure. The feeding cleaning assembly 6 is used to clean the surface of the upright before grinding, and the discharging cleaning assembly 7 is used to clean the surface of the upright after grinding. When the upright is located between the guide wheel 12 and the grinding wheel 9, the grinding wheel 9 is used to grind the surface of the upright, and the guide wheel 12 is used to limit the upright and drive it. Under the combined action of the grinding wheel 9, the upright is rotated and moved for grinding.
