Description

Technical Field

[0001] This invention relates to the field of cleaning devices for metal disc buckles, specifically a method for cleaning cement dust from the surface of metal disc buckles. Background Technology

[0002] Disc buckles are used to erect building scaffolding. During use, they inevitably get covered with cement dust and other deposits. When they are returned to the rental company or warehouse after use, the cement dust on the disc buckles (including horizontal bars, vertical bars, diagonal braces, etc.) needs to be cleaned so that they can be used again. The common method is to manually clean the cement dust by using a hammer to knock and scrape. This method is extremely labor-intensive, time-consuming, and inefficient, and it can also easily scratch the galvanized layer on the surface of the disc buckles. Summary of the Invention

[0003] The purpose of this invention is to provide a method for cleaning cement dust from the surface of disc buckles by replacing manual labor with machines, achieving automation, high efficiency, and significant labor savings.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A method for cleaning cement dust from the surface of a digital buckle includes an active container containing several free impactors. The digital buckle to be cleaned is placed inside the active container. During the movement of the active container, the free impactors collide with the digital buckle, causing the cement dust on the surface of the digital buckle to fall off. The active container is a rotating container.

[0005] This solution uses a machine to simulate manual tapping and scraping of the disc buckle surface to remove cement dust. An active container, capable of rotation or vibration (e.g., a rotating container), is used. The rotation of the container drives a free impactor to rotate or vibrate at a certain speed. After reaching a certain height within the rotating container, the impactor is thrown in a parabolic trajectory and then impacts the disc buckle upon landing. Although the disc buckle is heavy, it also tumbles along with the rotating container, causing collisions between the disc buckles. After sufficient rotation, the cement dust can be largely removed. Even if a small amount of cement dust remains, it will not affect the buckle's usability. Alternatively, a vibrating container can be used, using vibration to cause the impactor and the disc buckle to collide, simulating manual tapping and scraping. However, some disc buckle rods are quite long (6 meters), requiring a vibration table exceeding 6 meters in length, making it more difficult and costly to manufacture compared to a rotating container. Similarly, an oscillating container can also be used, but this is also more difficult and costly to manufacture.

[0006] As a further preferred embodiment of this technical solution, the rotating container includes a base, a horizontal roller, a roller drive device, and a control device. The horizontal roller and the roller drive device are mounted on the base, and the roller drive device is connected to the control device. The disc buckle and the free impactor are inside the horizontal roller. When the horizontal roller rotates, it carries the disc buckle and the free impactor to a certain height and then throws them off in a parabolic trajectory. As an embodiment of a rotary container, this solution uses a horizontal drum to hold multiple disc buckles to be cleaned. The horizontal drum is equipped with a door. When the geared motor is started, it drives the horizontal drum to rotate. The disc buckles and free impactors rotate inside the horizontal drum. Under appropriate speed control, the disc buckles and free impactors are carried to a certain height and then fly out in a parabolic trajectory to generate impact (if the speed is too slow, they will fall and will not fly out in a parabolic trajectory; if the speed is too fast, the centrifugal force will be too great and they will keep rotating with the horizontal drum and will not be able to fly out). The collision between the disc buckles or with the free impactors is equivalent to knocking the cement stuck to the disc buckles until the cement falls off. After a period of rotation, the door is opened and the cleaned disc buckles can be taken out. This can realize an automated, highly efficient, and labor-saving automatic cleaning process for disc buckles.

[0007] As a further preferred embodiment of this technical solution, the disc buckle can be one or more of a vertical pole, a horizontal pole, and a diagonal brace. The length of the rotating container in this solution is based on the longest disc buckle, while shorter disc buckles can also be placed inside the rotating container for dust removal. As a further preferred embodiment of this technical solution, the free impactor is a steel ball or steel segment, and the hardness of the steel ball or steel segment is not higher than the hardness of the disc buckle material. The size of the free impactor in this solution does not need to be very large. An excessively heavy free impactor will have a lower speed when flung, as it may fall quickly, resulting in insufficient impact force on the disc buckle, especially on disc buckles at a distance. A free impactor of appropriate weight, such as a smaller steel ball or steel segment, will have a higher initial velocity when carried upwards and flung by the horizontal roller, generating a greater impact force on the disc buckle. However, to avoid damaging the surface layer of the disc buckle, the hardness of the free impactor should not exceed the hardness of the disc buckle material.

[0008] As a further preferred embodiment of this technical solution, the material of the free impact body is Q235, Q215, or Q195. The scaffolding disc buckle is mainly made of Q345B / Q355B low-alloy steel pipe. In this solution, the material of the free impact body is Q235, Q215, or Q195, with a hardness not exceeding that of the scaffolding disc buckle material, so that the surface layer of the disc buckle will not be damaged upon impact.

[0009] As a further preferred embodiment of this technical solution, the horizontal drum employs multiple protrusions to carry the disc buckle and free impactor upwards during the drum's rotation. These protrusions can be levers protruding into the horizontal drum or protruding horizontal tubes arranged along the drum's axis. Compared to the smooth inner wall of the drum, these protrusions more easily carry the disc buckle and free impactor upwards, and after reaching a certain height, they do not prevent the disc buckle and free impactor from being thrown out along a parabolic path.

[0010] As a further preferred embodiment of this technical solution, the inner wall of the horizontal drum is equipped with a sound-absorbing rubber pad to reduce noise. This solution lays a rubber pad on the inner wall of the cleaning drum, which effectively absorbs and reduces the impact force of free impacting objects and the disc buckle on the horizontal drum during operation, while also reducing the impact noise from these impacting objects and the disc buckle.

[0011] As a further preferred embodiment of this technical solution, the horizontal drum is equipped with an automatic opening and closing door and a dust removal port. The horizontal drum in this solution uses an automatic opening and closing door to reduce workload; the dust removal port is used to clean the cement dust that has been knocked down from the horizontal drum.

[0012] As a further preferred embodiment of this technical solution, the horizontal roller is positioned and stopped, a limit block is provided on the horizontal roller, and a proximity switch corresponding to the limit block is provided on the base. The proximity switch is electrically connected to the control device, and the limit block is within the trigger range of the proximity switch when the horizontal roller stops rotating. This design involves installing a limit block on the horizontal roller and a proximity switch on the base. The horizontal roller rotates at approximately 30 revolutions per minute. The proximity switch detects the position of the upper limit block on the horizontal roller. Each time the machine stops, the electrical control system can detect the signal from the proximity switch to stop the horizontal roller at a fixed position. When the "stop" button of the electrical control system is pressed, if the limit block is within the sensing area of ​​the proximity switch, the electrical control system immediately controls the geared motor to stop the horizontal roller from rotating immediately. If the limit block is not within the sensing area of ​​the proximity switch when the "stop" button of the electrical control system is pressed, the horizontal roller will continue to rotate until the limit block on the horizontal roller enters the sensing area of ​​the proximity switch again (at most one more revolution). At this point, the electrical control system immediately controls the geared motor to stop the horizontal roller from rotating immediately, facilitating the automatic opening and closing of the horizontal roller door.

[0013] The present invention has the following beneficial effects: Replacing manual labor with machines achieves automation, high efficiency, and significant labor savings. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] This invention provides the following technical solution: A method for cleaning cement dust from the surface of a digital buckle includes an active container with several free impactors inside. The digital buckle to be cleaned is placed inside the active container. During the movement of the active container, the free impactors collide with the digital buckle, causing the cement dust on the surface of the digital buckle to fall off. The active container is a rotating container.

[0018] like Figure 1 As shown, the rotating container 1 includes a base 2, a horizontal roller 3, a roller drive device 4, and a control device 5. The horizontal roller 3 and the roller drive device 4 are mounted on the base 2. The roller drive device 4 is connected to the control device 5. The disc buckle and the free impactor are inside the horizontal roller 3. When the horizontal roller 3 rotates, it carries the disc buckle and the free impactor to a certain height and then throws them away in a parabolic trajectory.

[0019] A disc buckle can be one or more of the following: upright, horizontal, or diagonal brace.

[0020] The free impactor is a steel ball or steel segment, and the hardness of the steel ball or steel segment is no higher than the hardness of the disc buckle material.

[0021] The material of the free impactor is Q235, Q215, or Q195.

[0022] The horizontal drum 3 uses multiple protrusions to carry the disc buckle and free impact body upwards together when the horizontal drum rotates.

[0023] The inner wall of the horizontal drum 3 is equipped with a sound-absorbing rubber pad to reduce noise.

[0024] The horizontal drum 3 is equipped with an automatic opening and closing door and a dust removal port.

[0025] The horizontal roller is positioned and stopped. A limit block is provided on the horizontal roller, and a proximity switch corresponding to the limit block is provided on the base. The proximity switch is electrically connected to the control device. When the horizontal roller stops rotating, the limit block is within the trigger range of the proximity switch.

[0026] The specific working process of this invention is as follows: This solution uses a horizontal drum 3 to hold multiple disc buckles to be cleaned. The horizontal drum 3 is equipped with a door. The reduction motor is started to drive the horizontal drum 3 to rotate. The disc buckles and free impactors rotate inside the horizontal drum 3. Under appropriate speed control, the speed is about 30 revolutions per minute. After the disc buckles and free impactors are carried to a certain height, they will fly out in a parabolic trajectory and collide. The collision between the disc buckles or the collision with the free impactors is equivalent to knocking the cement on the disc buckles until the cement falls off. After a period of rotation, the door is opened and the disc buckles that have been cleaned can be taken out. This can realize an automated, highly efficient, and labor-saving automatic cleaning process for disc buckles.
