Description

Technical Field

[0001] The utility model relates to the technical field of experience devices, and in particular to a high-altitude operation fall impact experience device. Background Art

[0002] The so-called high-altitude work refers to the work performed by people at a height with a certain position as the reference. The national standard GB / T3608-2008 "Classification of High-altitude Work" stipulates: "High-altitude work refers to work performed at a height of 2m or more from the reference plane of the falling height where there is a possibility of falling." High-altitude work is a kind of special work. If the protective measures on the construction site are not in place, it is easy to cause casualties from falling. Therefore, when conducting safety production education, experience training on the high-altitude falling experience device can make high-altitude workers deeply aware of the hazards of falling from heights, and can personally experience the effects of falling impact in the process, which will greatly improve their safety awareness of high-altitude work, and then realize the importance of taking good anti-falling measures, which will minimize the probability of high-altitude falling accidents.

[0003] In order to achieve the experience function of simulating a fall from a height, the Chinese utility model patent with patent number 202121656507.4 discloses a high-altitude fall experience device. By setting a driving mechanism between the experience platform and the bracket, the experience platform is driven to drive the experiencer to fall quickly downward, which can ensure the safety of the experiencer and simulate the real feeling of falling, so that the experiencer can truly feel the danger of falling from a height, thereby improving the safety awareness of the operators. Although the high-altitude fall experience device can simulate a certain weightlessness effect after falling in specific safety training performance, the falling process of the personnel is not a free fall, and the personnel are not suspended in the air during the experience process. It cannot restore the hanging situation of the high-altitude workers due to protective measures, which deviates from the actual situation, making it difficult to fully reproduce the actual situation of the high-altitude operation fall accident, and the experience immersion is not strong, and it is difficult for the experiencer to combine it with specific safety production applications. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, a device for experiencing the impact of falling at height is provided. On the one hand, while ensuring the safety of the experience personnel, by realizing free fall, the hanging situation of the high-altitude workers due to protective measures is restored, and the falling process in the real high-altitude working environment is simulated, so that the experience personnel can feel the impact effect at the moment of falling. On the other hand, by expanding the detection and display of falling impact, the experience personnel can fully understand the relationship between the height of the fall and the magnitude of the falling impact force, and the important functionality of anti-fall protective equipment. It can also be used to conduct impact tests on the work safety belts to verify the safety of the protective equipment for high-altitude work.

[0018] The lifting ring is used to hang the release device on the shackle;

[0019] The rotating device is fixed to the top of the inner part of the shell;

[0020] The output shaft of the rotating device is connected to one end of the rotating shaft through the rotating connector, and the other end of the rotating shaft is connected to one end of the movable block;

[0021] The clockwise rotation of the rotating shaft drives the movable block to expand outward to form an open lock opening, and the counterclockwise rotation of the rotating shaft drives the movable block to contract inward to form a closed lock opening.

[0022] Based on the above, the portal frame includes two supporting columns and one fixing column;

[0023] The support column is assembled by a first support column and a second support column through a support column connector;

The components are connected and combined on site by splicing installation, and the height of the support column can be adjusted by installing the support column connector to achieve the effect of simulating different high-altitude operation environments. By controlling the lifting device to connect the release device for simultaneous linkage, the free fall phenomenon and effect of falling from a height at different heights are simulated. By installing a safety lock above the release device as a protection means during falling, the hanging protection effect of the safety belt during falling is simulated. A protective cushion is placed under the release area, which can further avoid the risk of injury to personnel during the falling experience. The weight information of the experiencer is collected by the impact force detection device, converted into a static force value and displayed in real time on the display device. The current impact force value change is displayed at the moment of falling and is continuously displayed for a certain period of time, so that the experiencer can intuitively see the impact force change of falling from a height at different heights. The experiencer can also wear a work safety belt to perform a safety belt impact test before work to verify that the protection performance of the test safety belt is normal and intact. By recreating the effects of fall accidents at different heights during high-altitude operations, the participants can truly feel the protective effect of the safety belt when falling. In the process of watching, participating and experiencing, the trainees can have a deeper understanding of the dangers of fall accidents and protective measures. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The support column 2 is assembled by connecting the first support column 5 and the second support column 7 via the support column connector 6, which is convenient for transportation and on-site installation. In other embodiments, when the site height is sufficient and there are special requirements for the experience height, the connector 6 can be replaced with a third support column to increase the height of the support column 2, and an extendable movement mechanism can be added between the first support column 5 and the second support column 7 to achieve the purpose of height adjustment within a certain range.

[0040] Further preferably, the limit device 10 includes a limit plate 16 arranged on the pull rope 15 and a limit switch arranged on the frame 1; the limit switch is electrically connected to the control system 13;

[0041] During the experience, the lifting device 9 controls the winch mechanism 14 to work upward and gradually retract the pull rope 15, and the limit plate 16 gradually rises along with the pull rope 15. When the pull rope 15 triggers the limit device 10 to move, the maximum height of the falling experience is reached, and the control system 13 controls the lifting device 9 to disconnect the power supply and stop working. At this time, it will no longer be able to lift upward, and the control system 13 is set to only control the lifting device 9 to work downward.

[0042] Further preferably, the release device 21 includes a shell, a lifting ring 22 arranged at the top of the shell, a rotating device 23 arranged inside the shell, a rotating connector 24, a rotating shaft 25 arranged in a rotating cylinder 26, and a movable block 27; the lifting ring 22 is used to hang the release device 21 on the shackle 18; the rotating device 23 is fixed to the top of the shell; the output shaft of the rotating device 23 is connected to one end of the rotating shaft 25 through the rotating connector 24, and the other end of the rotating shaft 25 is connected to one end of the movable block 27; the clockwise rotation of the rotating shaft 25 drives the movable block 27 to expand outward to form an open lock 28, and the counterclockwise rotation of the rotating shaft 25 drives the movable block 27 to contract inward to form a closed lock 28;

The clockwise rotation of the rotating shaft 25 drives the movable block 27 to expand outward. The expansion of the movable block 27 opens the lock 28. After the lock 28 is opened in place, the rotating device 23 stops rotating.

[0045] The experiencer wears the work safety belt, hangs on the release device 21, and performs the safety belt impact test before the operation to verify that the protective performance of the test safety belt is normal and intact. The lifting device 9 controls the hoisting mechanism 14 to work upward and gradually retract the pull rope 15. The pull rope 15 drives the release device 21 to lift upward, and the experiencer is suspended in the air.

The operator controls the release device 21 to release. At the moment of the experiencer falling, the display device 11 displays the current impact force value and retains it for a certain time, which is convenient for the experiencer to check after leaving the experience area, intuitively see and compare the changes in the impact force values ​​of falling at different heights, and enhance the awareness of the risk of falling from height.

[0046] The hook of the fall arrester 8 is fixed to the safety belt of the experiencer. During the experience, the release device 21 is released, and the experiencer's instantaneous fall will drive the fall arrester 8 to stop, so that the anti-fall function of the fall arrester can be experienced.

[0047] The safety lock 20 is removed from the experiencer's seat belt. The experiencer's seat belt is only connected to the release device 21. During the experience, the release device 21 is disengaged, and the experiencer loses the protection of the seat belt and safety rope and falls onto the protective cushion 12 in an instant, simulating a high-altitude shifting operation without the seat belt protection, ignoring the consequences of the risk of falling from a height.

[0048] The specific experience process of this utility model:

[0049] A frame 1 is fixed at the site, a pull rope 15 is installed on the hoisting mechanism 14 of the lifting device 9, an impact force detection device 17 is fixed under the pull rope 15, a shackle 18 and a connecting ring 19 are used to connect the impact force detection device 17 with a release device 21, and a fall arrester 8 is used to connect the release device 21 as back protection. When experiencing, the control system 13 is operated to run the experience device, and the safety lock 20 and the release device 21 are connected to the experiencer's safety belt.

The rising button of the remote control device is remotely pressed to control the rising action of the lifting device 9. The lifting device 9 drives the release device 21 to move upward through the connection of the pull rope 15. After the release device 21 reaches the experience height, stop pressing the rising button of the remote control device, and remotely press the release button of the remote control device to control the release action of the release device 21. The lock mouth 28 of the release device 21 will automatically fall into place. After the lock mouth 28 of the release device 21 is opened, the experiencer is pulled by the fixed safety lock 20 to fall within a certain distance, achieving the effect of free fall from a height. Before lifting, the impact force detection device 17 collects the experiencer's weight information and displays it in real time on the display device 11. The current impact force value change is displayed at the moment of falling and retained for a certain time. The remote control device is remotely pressed to control the lifting device 9 to descend, and the safety lock 20 is relaxed and no longer pulls. The experiencer opens the safety belt and leaves the experience area, and the experience process ends.

[0050] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
