Description

Technical Field

[0001] This utility model relates to the field of industrial protective covers, specifically to a protective cover for a dynamic balancing test bench for a transmission shaft. Background Technology

[0002] With the rapid development of modern industry, the operating speed and precision of various mechanical equipment are constantly improving. As a key component in many mechanical systems, the performance of the drive shaft directly affects the overall operating efficiency and stability of the equipment. Under high-speed rotation, imbalance in the drive shaft can cause strong vibrations and noise, not only reducing the service life of the equipment but also potentially leading to safety accidents. Therefore, precise dynamic balancing testing and adjustment of the drive shaft has become a crucial step in ensuring the normal operation of the equipment.

[0003] In existing technologies, during dynamic balancing tests, the drive shaft rotates at high speed, but the dynamic balancing test bench lacks protective measures. If the drive shaft itself has defects, is not securely installed, or has excessive imbalance, parts or fragments may fly off the drive shaft. Without a protective cover, these flying objects can cause serious injury to nearby operators, such as cuts or impacts. For example, similar accidents have occurred in some high-speed rotating machinery tests, posing a significant threat to personnel safety. For some open drive shaft dynamic balancing test benches, without a protective cover, operators working near the test bench may inadvertently or accidentally bring body parts (such as fingers, clothing, etc.) close to or into contact with the rotating drive shaft, thus being caught in it and suffering serious personal injury.

[0004] Without a protective cover, the drive shaft dynamic balancing test bench is also susceptible to contamination from the external environment. Dust, oil, and other contaminants in the air can adhere to components such as the drive shaft, sensors, and guide rails, affecting the normal operation and lifespan of the equipment. Prolonged exposure to such an environment can cause wear and corrosion of equipment parts, requiring more frequent maintenance and replacement, thus increasing maintenance costs. Without the shielding of a protective cover, the test bench components are also more vulnerable to factors such as ultraviolet radiation and temperature changes. For example, prolonged exposure to sunlight may cause plastic parts to age and become brittle, while metal parts may rust and corrode, thereby affecting the performance and lifespan of the equipment.

[0005] Currently, the shaft speed during dynamic balancing tests can reach up to 3000 rpm. The test bench generates considerable noise during operation. Without a protective cover, this noise directly propagates into the surrounding environment, potentially damaging the operator's hearing and affecting work comfort. Prolonged exposure to noise can lead to hearing loss, tinnitus, and other symptoms, impacting health and work order. Without a protective cover, counterweights can easily fall off and cause injury. The rotating drive shaft also causes airflow and vibration, potentially displacing or dropping tools and parts, disrupting normal operations. Furthermore, this unstable working environment can create psychological stress for operators, affecting work efficiency and quality. Utility Model Content

[0030] As attached Figure 1-2 As shown, this embodiment provides a protective cover for a dynamic balancing test bench for a transmission shaft, including several profiles 1, walls 2, rollers 3, springs 7, a canopy 4, a rotating claw 5, and a track 6.

[0031] like Figure 1 As shown, the profile 1 is divided into two groups, each group of profile 1 is evenly distributed on a surface, and the profiles 1 are parallel to each other; the wall 2 is fixedly connected to the two groups of profiles 1 respectively; the profile 1 is a square tube with a side length of 3cm and a thickness of 2mm. The wall 2 is a steel plate with a length of 1.7 meters, a height of 87cm, and a thickness of 3mm. The distance between two corresponding walls 2 is 70cm. The single rail groove of the track 6 is 4cm wide, and the double rail spacing is 66cm.

[0032] The canopy roof 4 can be welded to the upper part of the wall 2. The canopy roof 4 is 117cm above the ground, which facilitates the operator's movement and observation on the canopy roof 4.

[0033] like Figure 2 As shown, rollers 3 are installed at the bottom of the wall 2 to form a rolling connection; the rolling connection allows the operator to easily pull open the protective cover when needed, saving the operator's physical strength and attention. Two rollers 3 are installed at each end of the wall 2, each with a diameter of 10mm. The track 6 is 3 meters long.

[0034] The spring 7 has two ends connected to one end of the track 6 and the wall 2, respectively; the wall 2 is also provided with a rotating claw 5 that engages with the other end of the track 6. Simple stakes can be installed at both ends of the track 6, one end for securing the spring 7 and the other end for engaging the rotating claw 5. This design allows the protective cover to be retracted automatically by releasing the engagement between the rotating claw 5 and the end of the track 6 after the dynamic balancing test of the rotating shaft, thus saving the operator's physical effort and attention, and simplifying operation.

[0035] like Figure 1 As shown, the roof 4 has a herringbone structure with a slope to facilitate drainage and cleaning; the herringbone structure increases the surface area, which is beneficial for arranging more instruments as a dial.

[0036] The addition of column 9 strengthens the roof 4, protects the wall structure, and increases stability. Column 9 is 57cm long. Column 9 can also be made of metal square or round tubing.

[0037] like Figure 3 As shown, a timer 10 is installed on the roof 4 to facilitate the operator in timing the dynamic balancing experiment of the rotating shaft and to easily calculate the remaining time before the protective cover is opened.

[0038] A viewing window 11 is installed on the roof 4 to facilitate the operator's inspection of the internal working conditions. In case of unusual noises or smells, it is easy to see the internal situation and avoid direct contact or accidental injury. The glass of the viewing window 11 can be long strip tempered glass or reinforced glass, and it is mechanically or welded to the roof 4 with a groove of the corresponding shape and size.

[0039] The addition of the distress horn 12 will help to activate the horn and shout for help on-site in the event of an accident near the lab bench.

[0040] A buffer pad 13 is also provided between the wall 2 and the roller 3 to reduce the vibration transmitted by the track 6 or the ground to the protective cover, which helps the protective function of the protective cover, facilitates the need for visual observation, and can also extend its own life.

[0041] The roof 4 is also equipped with a running status indicator light 14. The light can be connected to the circuit of the test bench and powered on. When the test bench is running, the light is turned on; when the test bench stops, the light is turned off.

[0042] Lighting lamps 15 and 16 are also installed on the roof 4 and inside the wall 2 for operation and looking inside at night or in the dark.

[0043] Profile 1 can also be a metal round tube. The canopy 4 of the protective cover can also be equipped with a handle at the top, which can be made of 5mm steel rods.

[0044] The practical advantages of the protective cover are as follows:

[0045] Preventing flying debris: During dynamic balancing tests, the drive shaft rotates at high speed. If a malfunction occurs, such as a loose or broken part, fragments or components may fly out. A protective cover with a sliding track can effectively block these flying objects, preventing injury to nearby operators and greatly improving the safety of the testing process.

[0046] It also prevents personnel from getting caught in the drive shaft: When operators are working near the test bench, they may sometimes inadvertently get close to the rotating drive shaft. The protective cover forms a physical barrier to prevent personnel from accidentally getting their body parts caught in the drive shaft, reducing the risk to personal safety.

[0047] In terms of ease of operation: Flexible opening and closing: The sliding rail design makes the protective cover opening and closing smoother and more convenient. Operators can easily slide the protective cover open or close it as needed, saving operation time and improving work efficiency. For example, when installing or removing the drive shaft, the protective cover can be quickly opened for operation, and then closed afterward.

[0048] Furthermore, regarding equipment maintenance and lifespan: it prevents the drive shaft and other components on the test bench from being corroded by the external environment, such as dust, oil, and moisture. This helps reduce wear and damage, extend the equipment's lifespan, and lower maintenance costs. When maintenance of the test bench is required, the protective cover of the sliding rail can be easily opened, allowing operators to more easily access all parts of the equipment for cleaning, lubrication, inspection, and other maintenance work.

[0049] In terms of improving the working environment, it can also absorb and isolate the noise generated by the rotation of the drive shaft to a certain extent, improve the quietness of the working environment, and reduce the hearing damage and psychological impact of noise on operators. Keeping the work area clean: It can prevent the spread of pollutants such as debris and oil generated during the test to the surrounding work area, making the working environment cleaner and more hygienic, and facilitating subsequent cleaning work.

[0050] The above embodiments are merely one of the implementation methods to achieve the technical solution of this utility model. The scope of protection claimed by this utility model is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model.
