Description

Technical Field

[0001] This utility model relates to the field of rust removal equipment technology, and more specifically, to a low-vibration pneumatic hammer rust removal device. Background Technology

[0002] Rust removal equipment is a type of mechanical equipment specifically designed to remove rust and scale from the surface of objects. It uses physical, chemical, or electrochemical methods to restore the surface of objects to a clean and smooth state, thereby improving the performance, extending the service life, and enhancing the appearance of the objects. Physical rust removal uses mechanical force or the impact and friction of abrasives to remove rust, while chemical rust removal uses chemical reactions to dissolve or peel off the rust layer. Electrochemical rust removal equipment mainly uses an electrolytic cell, power supply, and electrode system to remove rust from the surface of objects.

[0003] A search revealed that publication number CN119388298A discloses a rust removal device for steel pipes, belonging to the technical field of rust removal equipment. It mainly includes a mounting frame; a clamping part, which includes a slide, a sliding mechanism, and a rotary motor. A first disc is mounted on the output end of the rotary motor, and a second cylinder is mounted on the other side of the mounting frame, with the output end of the second cylinder rotatably connected to the second disc; a grinding part, which includes two sets of tracks, on which at least one set of trolleys is mounted, and a grinding machine is mounted on each trolley, with a downward-sloping grinding belt on the grinding machine; and a collection mechanism, which includes a collection trough, with a discharge port on one side and a discharge pipe installed at the bottom of the discharge port. This rust removal device for steel pipes, by setting up the clamping and grinding parts, allows for uniform grinding of the exterior of the steel pipe in all directions. Simultaneously, by setting up the collection mechanism, the rust generated during grinding can be collected and quickly processed, preventing it from scattering everywhere. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Traditional rust removal equipment lacks effective vibration reduction design. The strong vibrations generated during impact operations are transmitted to the operator's arm almost without obstruction. Prolonged exposure to such high-intensity vibrations can easily lead to hand vibration syndrome, which not only harms physical health but also reduces work efficiency. Furthermore, the impact noise generated by rust removal equipment during operation is usually above 100 decibels, and there are no corresponding noise reduction measures. Being in such a noisy environment for a long time can seriously damage the operator's hearing. Moreover, high-decibel noise can also interfere with the surrounding work environment, reduce communication efficiency, and easily lead to safety accidents. In addition, most traditional rust removal equipment is not equipped with dust collection components, and a large amount of dust generated during the rust removal process flies around freely. If this dust is inhaled by the operator, it will irritate the respiratory tract and cause respiratory diseases such as coughing and asthma.

[0005] Therefore, a low-vibration pneumatic hammer rust removal device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a low-vibration pneumatic hammer rust removal device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a low-vibration pneumatic hammer rust removal device, comprising a rust removal mechanism, a limiting component, a dust collection component, a housing, and a flexible handle. The limiting component is installed below the rust removal mechanism, and the dust collection component is placed on the side of the limiting component. The housing is installed on the side of the rust removal mechanism, and the flexible handle is placed on the side of the dust collection component away from the limiting component. The rust removal mechanism includes a driving component and a transmission component, and the transmission component is installed below the driving component.

[0008] Preferably, the limiting assembly includes a telescopic rod, a guide tube, a retainer, and steel balls, wherein the retainer is placed on the outer diameter surface of the telescopic rod, the steel balls are embedded in the sidewall of the retainer, and the guide tube is placed on the outer diameter surface of the retainer.

[0009] Preferably, the vacuuming assembly includes a vacuum hood, a vacuum pipe, a collection box, and a negative pressure fan, wherein the vacuum pipe is installed on the side of the vacuum hood, the collection box is installed below the vacuum pipe, and the negative pressure fan is installed on the inner side of the collection box.

[0010] Preferably, the drive assembly includes a cylinder, a rubber damping pad, and an exhaust muffler, with the exhaust muffler mounted above the cylinder and the rubber damping pad mounted on the side of the cylinder.

[0011] Preferably, the transmission assembly includes an impact rod, a connecting plate, a spring damper, and a chisel head, with the connecting plate installed below the impact rod, the spring damper installed below the connecting plate, and the chisel head installed below the spring damper.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. Compared with existing technologies, this low-vibration pneumatic hammer rust removal equipment adopts a multi-stage vibration reduction design. Rubber vibration damping pads are set between the cylinder and the outer shell, which can absorb a large amount of vibration generated by the cylinder operation, reducing the transmission of vibration from the source. The spring vibration damper at the connection between the connecting plate and the chisel head can buffer the instantaneous energy of the impact, further reducing vibration transmission. At the same time, the flexible handle is filled with vibration-absorbing polyurethane foam, which provides additional protection for the arm, greatly reducing the vibration hazards to the operator and making the operation process more stable and comfortable.

[0014] 2. Compared with existing technologies, this low-vibration pneumatic hammer rust removal equipment indirectly reduces noise caused by component collisions through multi-stage vibration reduction design. It also equips the cylinder exhaust port with an exhaust muffler to reduce noise, and optimizes the structure and uses buffer materials in key parts to effectively reduce impact noise, create a relatively quiet working environment, protect the operator's hearing, and improve work concentration.

[0015] 3. Compared with existing technologies, this low-vibration pneumatic hammer rust removal equipment can collect dust from all directions through the dust collection component. The dust collection hood precisely covers the chisel head working area, and the flexible dust collection pipe transports the dust to a large-capacity collection box, ensuring a clean working environment and avoiding adverse effects of dust on the human body and equipment, thus providing a guarantee for high-precision processing.

[0021] 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.

[0022] Example 1

[0023] As attached Figures 1 to 4The low-vibration pneumatic hammer rust removal device shown includes a rust removal mechanism 1, a limiting component 2, a dust suction component 3, a housing 4, and a flexible handle 5. The limiting component 2 is installed below the rust removal mechanism 1, and the dust suction component 3 is placed on the side of the limiting component 2. The housing 4 is installed on the side of the rust removal mechanism 1, and the flexible handle 5 is placed on the side of the dust suction component 3 away from the limiting component 2. The rust removal mechanism 1 includes a drive component 6 and a transmission component 7, and the transmission component 7 is installed below the drive component 6.

[0024] Specifically: When workers use the rust removal equipment to remove rust from the surface of objects, the outer casing 4 of the rust removal equipment can provide a space for placing the objects. Before rust removal, workers need to place the part of the object that needs to be rusted under the rust removal mechanism 1, and then start the rust removal switch through the flexible handle 5. After the switch is started, the drive component 6 of the rust removal mechanism 1 will drive the transmission component 7 to move up and down, and remove rust from the rust spots on the surface of the object. While the transmission component 7 moves vertically, the limiting component 2 can ensure that the position of the transmission component 7 does not deviate, making the rust removal position more accurate. When the rust removal mechanism 1 removes rust from the object, it will generate a large amount of rust powder. This powder will fly in the air due to vibration. At this time, the dust collection component 3 will collect this powder to ensure the working environment of the workers.

[0025] Example 2

[0026] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0027] In a preferred embodiment, the limiting component 2 includes a telescopic rod 8, a guide tube 9, a retainer 10, and steel balls 11. The retainer 10 is placed on the outer diameter surface of the telescopic rod 8, and steel balls 11 are embedded in the side wall of the retainer 10. The guide tube 9 is placed on the outer diameter surface of the retainer 10. The steel balls 11 are embedded in the retainer 10 and can rotate freely. When the worker removes rust from the object, the transmission component 7 moves vertically under the drive of the drive component 6. At the same time as the transmission component 7 moves vertically, the telescopic rod 8 also moves vertically in the guide tube 9. The retainer 10 with embedded steel balls 11 isolates the telescopic rod 8 and the guide tube 9, so that the telescopic rod 8 and the guide tube 9 do not make direct contact. However, the telescopic rod 8, the guide tube 9, and the steel balls 11 on the retainer 10 make direct contact. Because the steel balls 11 can roll, there is rolling friction between the telescopic rod 8 and the steel balls 11, which greatly reduces the wear of the telescopic rod 8 and increases the smoothness of the movement of the telescopic rod 8.

[0028] In a preferred embodiment, the dust collection assembly 3 includes a dust collection hood 12, a dust collection pipe 13, a collection box 14, and a negative pressure fan 15. The dust collection pipe 13 is installed on the side of the dust collection hood 12, and the dust collection hood 12 and the dust collection pipe 13 are connected by threads. The collection box 14 is installed below the dust collection pipe 13, and the dust collection pipe 13 and the collection box 14 are connected by threads. The negative pressure fan 15 is bolted to the inner wall side of the collection box 14. When the rust removal equipment generates a large amount of rust powder during the rust removal process, the dust collection hood 12 confines this powder to a designated area to prevent the powder from drifting in the air. The powder in the dust collection hood 12 enters the collection box 14 through the dust collection pipe 13 because the negative pressure fan 15 creates negative pressure in the collection box 14.

[0029] In a preferred embodiment, the drive assembly 6 includes a cylinder 16, a rubber damping pad 17, and an exhaust muffler 18. The exhaust muffler 18 utilizes sound-absorbing material to absorb sound energy, thereby achieving noise reduction. The sound-absorbing material typically has porous and permeable characteristics. When sound waves enter these pores, they cause vibrations in the air molecules within the pores. Due to friction and viscous resistance, the sound energy is converted into heat energy and dissipated. The exhaust muffler 18 is model OXS-3. An exhaust valve is bolted to the top of the cylinder 16. The muffler 18 and the side of the cylinder 16 are bolted with rubber vibration damping pads 17. When the worker starts the flexible handle 5, the cylinder 16 will drive the transmission component 7 to move vertically. During the operation of the cylinder 16, the exhaust port of the cylinder 16 will generate a lot of noise. The exhaust muffler 18 installed at the exhaust port will absorb the noise and convert it into heat energy for consumption. The rubber vibration damping pads 17 sandwiched between the cylinder 16 and the outer shell 4 can reduce the vibration transmission of the cylinder 16 to the outer shell 4 during the operation of the cylinder 16.

[0030] In a preferred embodiment, the transmission assembly 7 includes an impact rod 19, a connecting plate 20, a spring damper 21, and a chisel head 22. The spring damper 21 is made of high-quality spring steel, which has high strength and good elasticity. The outer shell 4 is made of carbon steel and is treated with anti-corrosion to adapt to the harsh environment such as humidity and dust encountered by the rust removal equipment during operation. Its structure is compact and easy to install, and it can effectively isolate and reduce medium and high frequency vibrations. The connecting plate 20 is bolted to the bottom of the impact rod 19, the spring damper 21 is bolted to the bottom of the connecting plate 20, and the chisel head 22 is bolted to the bottom of the spring damper 21. After the drive assembly 6 is started, the drive assembly 6 will drive the connecting plate 20 to move vertically through the impact rod 19. During the vertical movement of the connecting plate 20, vibration will be generated. The spring damper 21 can reduce the transmission of vibration, making the chisel head 22 more stable during the rust removal process.

[0031] The working process of this utility model is as follows: First, when the worker uses the rust removal equipment to remove rust from the surface of the object, the outer shell 4 of the rust removal equipment can provide a space for the object to be placed. Before rust removal, the worker needs to place the object to be rusted under the rust removal mechanism 1, and then start the rust removal switch through the flexible handle 5. After the switch is started, the cylinder 16 of the drive component 6 will drive the transmission component 7 to move vertically. During the operation of the cylinder 16, the exhaust port of the cylinder 16 will generate a lot of noise, and the exhaust muffler 18 installed at the exhaust port will absorb the noise. The energy is converted into heat and consumed. The rubber damping pad 17 sandwiched between the cylinder 16 and the outer shell 4 reduces the vibration transmission from the cylinder 16 to the outer shell 4 during the operation of the cylinder 16. Under the drive of the drive assembly 6, the impact rod 19 of the transmission assembly 7 drives the connecting plate 20 to move vertically. The connecting plate 20 will vibrate during the vertical movement, and the spring damper 21 can reduce the vibration transmission, making the chisel head 22 more stable during the rust removal process. While the transmission assembly 7 moves vertically, the limiting assembly 2 can ensure the transmission. The position of component 7 will not deviate. When the limiting component 2 moves relative to the telescopic rod 8, the telescopic rod 8 will move vertically in the guide tube 9. A retainer 10 with embedded steel balls 11 separates the telescopic rod 8 and the guide tube 9, preventing direct contact between them. However, the telescopic rod 8, the guide tube 9, and the steel balls 11 on the retainer 10 make direct contact. Because the steel balls 11 can roll, there is rolling friction between the telescopic rod 8 and the steel balls 11, greatly reducing wear on the telescopic rod 8 and increasing the smoothness of its movement, thus facilitating rust removal. The positioning is more precise, and when the rust removal mechanism 1 removes rust from the object, it will generate a large amount of rust powder. This powder will fly in the air due to vibration. At this time, the dust collection hood 12 of the dust collection component 3 will limit this powder to a designated area to prevent the powder from scattering in the air. The powder in the dust collection hood 12 will enter the collection box 14 through the dust collection pipe 13 because the negative pressure fan 15 creates negative pressure in the collection box 14, thereby realizing the collection of this powder by the dust collection component 3 and ensuring the working environment of the workers. The above is the working principle of this low-vibration pneumatic hammer rust removal equipment.
