[0002] With the rapid development of modern industrial production, mechanical equipment is increasingly widely used in various fields. However, this has also brought about the frequent occurrence of mechanical injury accidents, among which V-belt entrainment accidents are particularly common and dangerous. In order to improve employees' safety awareness and response capabilities and reduce the occurrence of such accidents, a safety somatosensory mechanical injury V-belt entrainment simulation system has emerged. This system simulates a real mechanical working environment, allowing participants to personally experience the danger of V-belt entrainment, thereby enhancing safety awareness and improving operating skills.

[0003] As an important part of the transmission device, since the V-belt was invented by John Gates in 1917, the application of the V-belt in industrial production has had a development history of a hundred years. In industrial production, mechanical injury accidents are one of the important factors threatening employees' safety. V-belt entrainment accidents, due to their suddenness and high risk, have become typical representatives of mechanical injury accidents. Such accidents often occur during the operation of equipment. Due to improper operation or equipment failure, the V-belt suddenly entrains the body parts of the staff, causing serious injuries or even death. Therefore, how to effectively prevent and control V-belt entrainment accidents has become an important issue in enterprise safety production.

[0004] The safety somatosensory mechanical injury simulation system simulates a real mechanical working environment and accident scene. On the premise of ensuring the safety of participants, they can experience the danger of mechanical injury. This simulation system has characteristics such as intuitiveness, interactivity, and repeatability, and can significantly improve employees' safety awareness and response capabilities.

Detailed implementation manner

[0021] Combined with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to the attached Figure 1-6 , the safety somatosensory mechanical injury V-belt entrainment simulation system of this embodiment: includes a chassis 1, a driving pulley 2 and a driven pulley 3 are rotatably connected to the chassis 1, a connecting belt 4 is connected between the driving pulley 2 and the driven pulley 3, an adjusting pulley 5 is arranged in the middle of the connecting belt 4, a lifting block 6 is rotatably connected to the adjusting pulley 5, the lifting block 6 is slidably connected to the chassis 1, a belt tightener 7 is arranged at the lower end of the adjusting pulley 5, and the belt tightener 7 is located at the lower end of the connecting belt 4.

[0023] Both the driving pulley 2 and the driven pulley 3 are connected to the chassis 1 through a rotating shaft. The chassis 1 is equipped with a motor for driving the driving pulley 2 to rotate. The driving pulley 2 and the driven pulley 3 are connected by a connecting belt 4. The driving pulley 2 drives the driven pulley 3 to rotate synchronously through the connecting belt 4. The driven pulley 3 and the driving pulley 2 are not at the same height. An adjusting pulley 5 is installed between the driving pulley 2 and the driven pulley 3 for transition. At the same time, in order to prevent the connecting belt 4 from being too loose, a belt tightener 7 is installed at the lower end of the connecting belt 4. The belt tightener 7 is used to increase the tension of the connecting belt 4 and prevent the connecting belt 4 from slipping during operation.

[0024] The fixing bracket 8 is installed in the chassis 1, the cylinder 9 is installed on the fixing bracket 8, the lifting block 6 is installed on the cylinder 9, the movement of the lifting block 6 is driven by the telescopic movement of the cylinder 9, the movement of the lifting block 6 drives the movement of the adjusting pulley 5, and the pin shaft of the adjusting pulley 5 can move vertically in the chute 10. By lifting and lowering the lifting block 6, the position of the adjusting pulley 5 can be changed, so as to change the positional structure of the driving pulley 2, the driven pulley 3 and the adjusting pulley 5, and achieve the purpose of tightening the connecting belt 4.

[0025] The tightener 7 is composed of a first rod 701, a second rod 703 and a connecting shaft 702. The connecting shaft 702 connects the first rod 701 and the second rod 703. The first rod 701 is located below the connecting belt 4. As Figure 3 shown, when the first rod 701 rotates counterclockwise, the first rod 701 will push the connecting belt 4 upward, and the connecting belt 4 will form a bend. The route of the connecting belt 4 is stretched, so that the connecting belt 4 can achieve the purpose of tensioning. The tightener 7 cooperates with an elastic member. The elastic member can be a spring. The spring is connected to the second rod 703. The spring can pull the second rod 703 to rotate counterclockwise. Further, the elastic member can also be a torsion spring 11. The torsion spring 11 has a counterclockwise torsional force on the connecting shaft 702. The torsion spring 11 has a counterclockwise torsional force on the first rod 701 through the connecting shaft 702. When the connecting belt 4 is loose, under the action of the torsion spring 11, the first rod 701 rotates counterclockwise. Under the action of the torsion spring 11, the counterclockwise rotation of the first rod 701 can automatically fasten the connecting belt 4, realizing the automatic tensioning function of the connecting belt 4 and avoiding the situation of the connecting belt 4 slipping during the working process.

[0026] Further, in order to prevent the connecting belt 4 from derailing, a fixing block 13 is installed between the adjusting pulley 5 and the driven pulley 3. Two limiting rollers 14 are rotatably connected to the fixing block 13. The two limiting rollers 14 are located on the front and back sides of the connecting belt 4. The position of the connecting belt 4 is limited by the limiting rollers 14 to prevent the connecting belt 4 from derailing and ensure the normal operation of the device.

[0027] The protective cover 15 is located at the outer ends of the driven pulley 3 and the driving pulley 2. The protective cover 15 seals the surroundings of the driving pulley 2 and the driven pulley 3, preventing the hand from reaching into the connecting belt 4 and ensuring the safety of the user. The user can observe the interior through the observation port 16. The grid door 17 is installed at the observation port 16 through a hinge. The opening and closing grid door 17 can facilitate the opening and closing of the grid door 17 and at the same time does not affect the viewing of the internal components of the protective cover 15.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
