Description

Technical Field

[0001] This utility model belongs to the technical field of safety education simulation equipment, specifically relating to a high-altitude falling object simulation device. Background Technology

[0002] Accidents involving falling objects from heights are common at construction sites, with numerous cases of workers being injured or even killed due to not wearing safety helmets. Safety helmets, as crucial head protection equipment, effectively prevent head injuries from impacts and falling objects, thus mitigating the impact of accidents and ensuring worker safety. Wearing safety helmets is a key measure for maintaining the safety of personnel at construction sites; proper use of safety helmets can significantly reduce the mortality rate in accidents.

[0003] However, current education on the dangers of falling objects from heights and the importance of safety helmets mainly rely on watching relevant accident videos. This makes it difficult for workers to intuitively perceive the potential dangers of falling objects, leading to frequent instances of not wearing safety helmets and unsatisfactory training results. Therefore, this invention proposes the design of a falling object simulation device. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides a high-altitude falling object simulation device, which has a good safety education effect, can effectively improve workers' safety awareness, and is of superior quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-altitude falling object simulation device, comprising a frame, with rollers fixedly installed around the bottom of the frame by screws, a winch fixedly installed at the top of the frame by several bolts, a power connection line fixedly connected to the input end of the winch, a control switch fixedly connected to the power connection line, and the control switch fixedly installed at the front right side of the frame by several screws, a steel wire rope wound on the winch, a through hole opened at the middle of the top of the frame, through which the steel wire rope passes, guide pulleys fixedly installed at both ends of the inner side of the top of the frame by screws, and the steel wire rope passing through between the two guide pulleys, and several steel wire ropes fixedly connected around the bottom of the steel wire rope;

[0006] The bottom ends of several steel wire ropes are fixedly connected to an electromagnetic chuck. The input end of the electromagnetic chuck is fixedly connected to a second power supply line. A conduit is welded and fixed to the left front end of the upright frame, and the second power supply line passes through the conduit. A second control switch is fixedly connected to the second power supply line. A simulated falling object is magnetically attracted to the bottom end of the electromagnetic chuck.

[0007] A base is fixedly installed on the inner side of the bottom end of the stand by several bolts. A drawer is opened at the front end of the base. A drawer box is slidably connected inside the drawer. A pull handle is fixedly installed at the middle of the front end of the drawer box by screws. A head mold is fixedly installed at the middle of the bottom end of the drawer box by screws.

[0008] The upper end of the base is provided with a groove, and the upper end of the stand is provided with an explosion-proof transparent glass cover. The bottom end of the explosion-proof transparent glass cover is fitted and connected to the groove and fixed by adhesive.

[0009] As a preferred technical solution of the high-altitude falling object simulation device of this utility model, the simulated falling object is a metal component.

[0010] As a preferred technical solution of the high-altitude falling object simulation device of this utility model, the head mold is a metal component.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model mainly consists of a frame, a winch, an electromagnetic chuck, a base, a drawer, and an explosion-proof transparent glass cover. In use, the winch, steel wire rope, and steel wire hoisting rope can raise the electromagnetic chuck, which holds a simulated falling object, to a predetermined height. Then, the simulated falling object on the electromagnetic chuck is released and allowed to fall freely. The simulated falling object will collide with the safety helmet that is pre-placed on the head mold inside the drawer. The explosion-proof transparent glass cover can visually demonstrate the impact damage of the falling object. This device has a good safety education effect and can effectively improve workers' safety awareness. It is of superior quality.

[0013] In the process of using this utility model, the guide pulley guides the wire rope, which can ensure that the electromagnetic chuck and the simulated falling object can move up and down along the central axis, so as to realize that the simulated falling object accurately hits the safety helmet on the head model, which is of better use.

[0014] In the process of using this utility model, the simulated falling object can be easily brought to a predetermined height by adsorbing it with an electromagnetic chuck, and it is easy to release it quickly. In addition, the simulated falling object can be flexibly replaced with different specifications and types for use, making it a better choice.

[0015] In the process of using this utility model, by setting up a drawer and head mold, it is convenient to place and fix the safety helmet in the center. After the simulation experiment, the drawer can be pulled out, which makes it easy to take out and replace the safety helmet in the drawer, as well as take out the simulated falling object in the drawer. It is better to use.

[0016] In the process of using this utility model, by setting an explosion-proof transparent glass cover, it is possible to prevent simulated falling objects from being ejected during the simulation process, thus avoiding injury to surrounding personnel. At the same time, the transparency of the explosion-proof transparent glass cover makes it easy for workers to see and feel the object intuitively, making it a better choice.

The specific connection and use of the winch 3, power connection line 4, control switch 5 and steel wire ropes 6 are existing known technologies and will not be described in detail here. The power connection line 4 is not fully shown. The winch 3 and steel wire ropes 6 enable the electric lifting and lowering of the electromagnetic chuck 10 and the simulated falling object 14. The guide pulley 8 guides the steel wire rope 6 to ensure that the electromagnetic chuck 10 and the simulated falling object 14 can move up and down along the central axis, so as to achieve the accurate impact of the simulated falling object 14 on the safety helmet on the head mold 19.

[0029] Reference Figure 1 and Figure 5As shown, furthermore, the bottom ends of several steel wire ropes 9 are jointly and fixedly connected to an electromagnetic chuck 10. The input end of the electromagnetic chuck 10 is fixedly connected to a power connection cable 11. A conduit 12 is welded and fixed to the left front end of the support frame 1, and the power connection cable 11 passes through the conduit 12. A control switch 13 is fixedly connected to the power connection cable 11. A simulated falling object 14, which is a metal component, is magnetically attracted to the bottom end of the electromagnetic chuck 10. The specific connections and uses of the electromagnetic chuck 10, the power connection cable 11, and the control switch 13 are detailed below. As these are existing known technologies, they will not be described in detail here. The power connection cable 11 is not fully shown. The conduit 12 is used for guiding and supporting the middle section of the power connection cable 11. The simulated falling object 14 is made of a metal material that can be magnetically attracted by the electromagnetic chuck 10, such as iron, or other metal materials that can meet its usage requirements. By attracting the simulated falling object 14 through the electromagnetic chuck 10, the simulated falling object 14 can be easily brought to a predetermined height and is easy to release quickly. In addition, the simulated falling object 14 can be flexibly replaced with different specifications and types for use.

[0030] Reference Figure 1 , Figure 6 and Figure 7 As shown, further, a base 15 is fixedly installed on the inner side of the bottom end of the support frame 1 by several bolts. A drawer 16 is opened at the front end of the base 15. A drawer box 17 is slidably connected inside the drawer box 16. A pull handle 18 is fixedly installed at the middle of the front end of the drawer box 17 by screws. A head mold 19 is fixedly installed at the middle of the bottom end of the drawer box 17 by screws. The head mold 19 is a metal component. By setting the drawer box 17 and the head mold 19, it is convenient to place and fix the safety helmet in the center. After the simulation experiment, the drawer box 17 can be pulled out to easily take out and replace the safety helmet in the drawer box 17, as well as take out the simulated falling object 14 simulated after the experiment.

The bottom end of the explosion-proof transparent glass cover 21 is fitted and connected to the groove 20 and fixed by adhesive. By setting the explosion-proof transparent glass cover 21, the simulated falling object 14 can be prevented from popping out during the simulation, avoiding injury to the surrounding personnel. At the same time, the transparency of the explosion-proof transparent glass cover 21 makes it easy for workers to see and feel it intuitively.

[0032] In this implementation plan: This utility model mainly consists of a frame 1, a winch 3, an electromagnetic chuck 10, a base 15, a drawer 17, and an explosion-proof transparent glass cover 21. In use, the winch 3, steel wire rope 6, and steel wire hoisting rope 9 can raise the electromagnetic chuck 10, which holds the simulated falling object 14, to a predetermined height. Then, the simulated falling object 14 on the electromagnetic chuck 10 is released and allowed to fall freely.

The impact damage of the falling object can be visually displayed through the explosion-proof transparent glass cover 21. This device has a good safety education effect and can effectively improve workers' safety awareness. It is of good quality.

[0033] The usage process and working principle of this utility model are as follows: Figure 1 As shown, the electromagnetic chuck 10, which is connected to an external power source via the power connection cable 11, can be controlled remotely by the operator via the control switch 13 on the power connection cable 11. This releases the simulated falling object 14 on the electromagnetic chuck 10, which undergoes free fall and collides with the safety helmet that is pre-worn on the head mold 19 inside the drawer 17. The impact damage of the falling object can be visually displayed through the explosion-proof transparent glass cover 21, which has a good safety education effect and can effectively improve workers' safety awareness. It is the best choice for use.

[0034] After the simulation, the drawer box 17 can be pulled out from the base 15 through the drawer cavity 16 using the pull handle 18. This allows for the replacement of the safety helmet on the head mold 19 and the removal of the simulated falling object 14 from the drawer box 17. Then, the drawer box 17 is pushed back in. Next, the winch 3, which is connected to an external power source via the power connection cable 14, is operated using the control switch 15 on the power connection cable 14. The winch 3 releases the wire rope 6 and guides it through the guide pulley 8 to lower the electromagnetic chuck 10 to a suitable height. Then, the electromagnetic chuck 10 is operated using the control switch 2 13 to place the simulated falling object 14 at the bottom of the electromagnetic chuck 10 and be picked up by it. Finally, the winch 3 is operated using the control switch 15 to wind up the wire rope 6 and raise the electromagnetic chuck 10, which holds the simulated falling object 14, to a predetermined height for the next simulation.
