Description

Technical Field

[0001] This utility model belongs to the field of safety protection equipment technology, specifically relating to a high-altitude fall protection safety device. Background Technology

[0002] In high-altitude operations, workers may fall accidentally due to weather, equipment failure, or human error. Without the protection of fall arrestors, workers may suffer serious injuries or even lose their lives. Fall arrestors can effectively prevent workers from falling to the ground when they fall accidentally, thus ensuring their safety.

[0003] Chinese patent application number 202223125837.8 discloses a high-altitude fall protection device, comprising two sets of horizontal beam assemblies installed in parallel left and right directions, with a safety net installed between the two sets of horizontal beam assemblies. The safety net and the two sets of horizontal beam assemblies form a safety bearing surface. Cross support frames are movably installed on the front and rear sides below the two sets of horizontal beam assemblies, and each of the two cross support frames consists of two cross-hinged support legs. The lower ends of the four support legs are limited by casters and installed in rails, and the four rails are fixedly installed on the ground. This utility model uses two sets of horizontal beam assemblies connected to a safety net and two cross support frames to form a buffer for people or objects falling from a height. It achieves the safety protection effect of protecting people or objects from falling from a height by absorbing the weight of the falling object through the safety net and by the dissipation of the weight of the falling object through the elastic elongation deformation of the spring under gravity.

[0004] The aforementioned disclosed patents have the following problems when used:

[0005] 1. The device is supported by guide rails during use. The contact area between the guide rails and the ground is small and there are no fixing components, so the stability of the device cannot be guaranteed during use. At the same time, the addition of a load-bearing flower bed makes the device inconvenient to use and store, and its practicality is not high.

[0006] 2. This device protects falling objects or people with a safety net, but there are no side guards on either side of the safety net. Falling people or objects may bounce up under the action of the safety net and roll to one side, which is not very safe and is not conducive to widespread promotion. Utility Model Content

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] Please see Figure 1-3 The present invention provides the following technical solution: a high-altitude fall protection device, including an outer frame beam 1, an inner frame beam 2 provided on one side of the outer frame beam 1, a spring 3 provided at the contact point between the outer frame beam 1 and the inner frame beam 2, a wire rope sleeve 8 sleeved on the surface of the inner frame beam 2, a safety net 4 provided on one side of the inner frame beam 2, a support leg 7 provided at the bottom of the outer frame beam 1, a guide rail 5 provided at the bottom of the support leg 7, a limit component 6 provided at the bottom of the guide rail 5, and a side stop component 9 provided on one side of the outer frame beam 1.

[0024] Specifically, the limiting component 6 includes a pin hole 61, a mounting plate 62, a slot 63, a limiting block 64, an anti-slip block 65, a locking block 66, and a mounting bolt 67. The bottom of the guide rail 5 is provided with a mounting plate 62, the surface of the mounting plate 62 is provided with a limiting block 64, one side of the limiting block 64 is provided with a pin hole 61, the side of the limiting block 64 away from the pin hole 61 is provided with a mounting bolt 67, the bottom of the mounting plate 62 is provided with an anti-slip block 65, one side of the surface of the mounting plate 62 is provided with a slot 63, and the side of the mounting plate 62 away from the slot 63 is provided with a locking block 66.

[0025] By adopting the above technical solution, when using the limiting component 6, the guide rail 5 is first installed on the surface of the mounting plate 62, and the guide rail 5 is limited and fixed by the limiting block 64. The anti-slip block 65 enables the device to be used on a relatively smooth ground, preventing the device from shifting due to the low friction between the mounting plate 62 and the ground. The mounting bolt 67 allows the device to be pre-installed in the required location, which is convenient for construction and protects personnel safety. The pin hole 61 makes it easy to fix the device on a soft ground surface. When the protection area of ​​the safety net 4 is insufficient, multiple devices can be fixed by engaging the slot 63 and the locking block 66. This does not affect the stability of the device and improves its practicality. This process also avoids the need to suspend the load-bearing flower bed on the support leg 7 when the device is in use, making the device easier to store and use.

[0026] Specifically, a baffle is provided at one end of the interior of the card slot 63.

[0027] By adopting the above technical solution, when it is necessary to engage the card slot 63 and the card block 66, the baffle can limit the card block 66, making it easier for the card block 66 to fully engage with the card slot 63, thus improving stability.

[0028] In this embodiment, when using the limiting component 6, the guide rail 5 is first installed on the surface of the mounting plate 62. The guide rail 5 is fixed by the limiting block 64. The anti-slip block 65 allows the device to be used on relatively smooth ground, preventing the device from shifting due to low friction between the mounting plate 62 and the ground. The mounting bolt 67 allows the device to be pre-installed in the required location, facilitating construction and protecting personnel safety. The pin hole 61 allows the device to be easily fixed on soft ground surfaces. When the protection area of ​​the safety net 4 is insufficient, multiple devices can be fixed by engaging the slot 63 and the block 66. This does not affect the stability of the device and improves its practicality. This process also avoids the need to suspend the load-bearing flower bed on the support leg 7 during use, making the device easier to store and use. When it is necessary to engage the slot 63 and the block 66, the baffle can limit the block 66, making it easy for the block 66 to fully engage with the slot 63, thus improving stability.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that, specifically, the side guard assembly 9 includes a guard net 91, a limiting frame 92, a connecting plate 93, a through hole 94, a base 95, a column 96, and a spring 97. The base 95 is provided on one side surface of the outer frame beam 1, the column 96 is provided on the top surface of the base 95, the spring 97 is provided inside the column 96, the guard net 91 is provided on one side of the spring 97, the through hole 94 is provided on the surface of the guard net 91, the connecting plate 93 is provided on one side of the base 95, and the limiting frame 92 is provided on the top of the connecting plate 93.

[0031] By adopting the above technical solution, when using the side guard assembly 9, firstly, the guard net 91 inside the column 96 is pulled out, passes through the limiting frame 92, and then the guard net 91 is engaged with the limiting groove by the card plate at one end. Then, the guard net 91 is connected to the safety net 4 through the through hole 94. When in use, while the safety net 4 moves downward under force, the limiting frame 92 simultaneously drives the guard net 91 to move downward, so that the guard net 91 can effectively prevent falling objects and people. The safety net 4 and the guard net 91 are connected through the through hole 94, which prevents falling objects or people from rolling out from the gap at the contact point between the two. The spring 97 facilitates the storage of the guard net 91, thereby solving the problem that falling objects or people will not bounce up and roll to one side. It is convenient to store and improves the safety performance of the device.

[0032] Specifically, a limiting groove is provided inside the upright post 96 on the side of the baffle 91 away from the spring 97, and a retaining plate is provided at the end of the baffle 91 near the limiting groove.

[0033] By adopting the above technical solution, the efficiency of use is improved by inserting the card plate into the limiting groove during use.

[0034] Specifically, a fastening bolt is provided on one side surface of the limiting frame 92, and a stop block is provided on the side end of the fastening bolt near the baffle 91.

[0035] By adopting the above technical solution, the surface of the barrier net 91 can be fixed by fastening bolts and abutments, thereby keeping the barrier net 91 taut and ensuring the effectiveness of fall prevention.

[0036] In this embodiment, when using the side guard assembly 9, first pull out the guard net 91 inside the column 96, pass it through the limiting frame 92, and then engage it with the limiting groove via the locking plate at one end of the guard net 91. Then, connect the guard net 91 to the safety net 4 through the through hole 94. During use, as the safety net 4 moves downward under force, the limiting frame 92 simultaneously drives the guard net 91 downward, enabling the guard net 91 to effectively prevent falling objects and people from falling. Connecting the safety net 4 and the guard net 91 through the through hole 94 prevents falling objects or people from rolling out from the gap at the contact point. The spring 97 facilitates the storage of the guard net 91, thus preventing falling objects or people from bouncing and rolling to one side. This facilitates storage and improves the safety performance of the device. During use, by engaging the locking plate into the limiting groove, the efficiency of use is improved. The surface of the guard net 91 can be fixed by the fastening bolts and the abutment, thus keeping the guard net 91 taut and ensuring the effectiveness of the fall prevention.

[0037] The structure and operating principle of the spring 3, guide rail 5 and wire rope sleeve 8 in this utility model have been disclosed in a high-altitude fall protection device disclosed in Chinese patent application number 202223125837.8.

[0038] The working principle and usage process of this utility model: This utility model adjusts a high-altitude fall protection device. When using the limiting component 6, the guide rail 5 is first installed on the surface of the mounting plate 62. The guide rail 5 is limited and fixed by the limiting block 64. The anti-slip block 65 allows the device to be used on relatively smooth ground, preventing the device from shifting due to low friction between the mounting plate 62 and the ground. The mounting bolt 67 allows the device to be pre-installed at the required location, facilitating construction and protecting personnel safety. The pin hole 61 allows the device to be easily fixed on soft ground surfaces. When the protection area of ​​the safety net 4 is insufficient, multiple devices can be fixed by engaging the slot 63 and the block 66. This does not affect the stability of the device and improves its practicality. This process also avoids the need to suspend the heavy flower bed on the support leg 7 during use, making the device easier to store and use. When it is necessary to engage the slot 63 and the block 66, the baffle can limit the block 66, making it easy for the block 66 to fully engage with the slot 63. This invention improves stability by adjusting a high-altitude fall protection device. When using the side guard assembly 9, firstly, the guard net 91 inside the column 96 is pulled out, passes through the limiting frame 92, and then engages with the limiting groove via a locking plate at one end of the guard net 91. Then, the guard net 91 is connected to the safety net 4 through the through hole 94. During use, as the safety net 4 moves downwards under force, the limiting frame 92 simultaneously drives the guard net 91 downwards, enabling the guard net 91 to effectively protect falling objects and people. Hole 94 connects safety net 4 to barrier net 91, preventing falling objects or people from rolling out through the gap at the contact point. The spring 97 facilitates the storage of barrier net 91, thus preventing falling objects or people from bouncing and rolling to one side. This facilitates storage and improves the safety performance of the device. During use, the card plate is inserted into the limiting groove, improving efficiency. The surface of barrier net 91 can be fixed by fastening bolts and abutments, keeping barrier net 91 taut and ensuring the effectiveness of fall prevention.
