Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric power operation, in particular to an electric power aerial operation construction anti-falling device. BACKGROUND

[0002] The anti-falling device is a safety device used in high-altitude operation to prevent personnel or objects from falling, commonly known as a speed difference device or a self-controlled anti-falling device, which mainly functions to trigger a braking action through a change in speed when falling occurs, thereby effectively protecting the safety of the user.

[0003] Commonly used anti-falling devices include flexible anti-falling devices and rigid anti-falling devices. The flexible anti-falling device is made of flexible materials such as stainless steel wire, steel-cored aluminum wire, or galvanized steel wire, etc. This device is more flexible and can effectively buffer the impact force generated during falling, thereby reducing harm to the user. The rigid anti-falling device, also known as a hard anti-falling device, is usually made of rigid materials such as steel rails, etc., and has high stability and fixity, suitable for high-altitude operation environments that require high stability, such as construction, steel, and shipbuilding fields.

[0004] In related technologies, such as Chinese patent CN118341013A, a rigid guide rail type anti-falling device is disclosed. When in use, the worker needs to pull the anti-falling device to move on the rigid guide rail body while moving on the operation platform, thereby facilitating movement and construction, and maintaining protection at all times. When the worker falls due to an accident, the safety rope will be pulled, and the safety rope will pull the lower block through the first and second circular rings, causing the lower block to swing through the circular sleeve. When the lower block swings, the rotating bar will drive the sliding block to slide into the first air cavity, causing the gas inside the first air cavity to enter the second air cavity through the first and second gas conveying channels, and the pressing block will slide outward and press against the rigid guide rail body, achieving double self-locking.

[0005] Although the above-mentioned rigid guide rail type anti-falling device can improve the protection effect to some extent, it is found in actual use that when the worker is operating at high altitude, the anti-falling device is below the worker, causing the worker to need to descend a certain distance to trigger the self-locking function of the anti-falling device when falling. During the falling process, the worker may collide with surrounding objects, thereby easily causing safety accidents. Moreover, because the worker has already descended a certain distance, the worker's kinetic energy is large, which on the one hand increases the instantaneous force on the anti-falling device, reducing its service life, and on the other hand causes the worker to suffer greater harm. SUMMARY

[0038] AsFigures 1 to 9 As shown in the drawings, the power aerial construction anti-falling device provided by the embodiment of the present application is used to lock the worker on the guide rail when the worker falls, and is provided with two sliding seats 1, both of which are sleeved on the guide rail, are arranged at intervals along the extension direction of the guide rail, and can elastically slide along the extension direction of the guide rail, and can slide relative to each other; each sliding seat 1 is elastically hinged with a locking part 11, which is configured to be connected with the safety rope on the worker, and is configured to have a moving state and a locking state, in the moving state, the locking part 11 is separated from the guide rail, and in the locking state, the locking part 11 is frictionally locked with the guide rail; each sliding seat 1 is provided with a sliding locking part, which is configured to lock the position of the sliding seat 1 on the guide rail.

[0039] Specifically, in the embodiment, as shown in the drawings, Figure 2 The sliding seat 1 is provided with a base body 101 and two mounting tables 102, wherein the base body 101 is provided in the shape of a rectangular block structure, the mounting table 102 is provided in the shape of a T-shaped block structure, and has a horizontal section and a vertical section which are vertically and fixedly connected, the mounting table 102 is provided in the installation that the left end of the horizontal section is fixedly and vertically connected on the right side wall of the base body 101, and the two mounting tables 102 are symmetrically arranged; in use, the guide rail passes through between the two mounting tables 102 on the same sliding seat 1.

[0040] As shown in the drawings, Figure 4 The locking part 11 is provided in the shape of an L-shaped block structure, and the inflection point of the locking part 11 is hinged on the base body 101; in order to facilitate the installation of the locking part 11, mounting holes are provided on the left and right side walls of the base body 101, and shafts are vertically connected on the front and rear side walls of the mounting holes, and the locking part 11 is provided in the installation that the inflection point thereof is sleeved on the shafts in a rotatable manner.

[0041] More specifically, in order to facilitate the elastic hinging of the locking part 11, as shown in the drawings, Figure 4 A first tension spring 13 is connected between the right end left side wall of the locking part 11 and the sliding seat 1, and under the action of the first tension spring 13, the locking part 11 has a tendency to rotate in the clockwise direction around the shaft.

[0042] In use, first, the two sliding seats 1 are sleeved on the guide rail, and then the safety rope on the worker is connected to the two locking parts 11 respectively, when the worker moves in the vertical direction on the operation platform, the safety rope can drive the lower sliding seat 1 to move on the guide rail, and the lower sliding seat 1 then drives the upper sliding seat 1 to move on the guide rail, so that the worker is always located between the two sliding seats 1; in the process of moving the sliding seat 1, as shown in the drawings, Figure 4As shown, the locking portion 11 is in a moving state and is away from the guide rail, so as to avoid the frictional contact between the locking portion 11 and the guide rail and affect the movement of the sliding seat 1. The sliding seat 1 can be locked on the guide rail under the action of the sliding locking portion and is prevented from falling. When the worker falls by accident, the locking portion 11 located above is above the worker, so that the worker can trigger the self-locking function of the fall arrester by falling a short distance, so as to avoid the damage to the fall arrester and the worker caused by the excessive kinetic energy when the worker falls. In the process of falling of the worker, the worker drives the locking portion 11 to rotate around the rotating shaft in the counterclockwise direction through the safety rope on the body, so as to switch the locking portion 11 from the moving state to the locking state, as shown in Figure 5 As shown, the locking portion 11 is in a locking state and is in frictional locking with the guide rail. When the locking portion 11 located above fails, the locking portion 11 located below can still trigger the self-locking function of the fall arrester, so as to achieve double insurance.

[0043] In some embodiments, the power high-altitude operation construction fall arrester is further provided with a first elastic member connected between the two sliding seats 1. Under the action of the first elastic member, the two sliding seats 1 have a tendency to move away from each other.

[0044] In use, the sliding seat 1 located below can drive the sliding seat 1 located above to move along the guide rail through the first elastic member, so that the worker is always located between the two sliding seats 1.

[0045] In further embodiments, the first elastic member is provided with a compression spring 2.

[0046] In this embodiment, the compression spring 2 is arranged to be connected at the top end to the bottom of the sliding seat 1 located above and connected at the bottom end to the top of the sliding seat 1 located below during installation.

[0047] In use, when the worker moves in the vertical direction on the operation platform, the worker can drive the sliding seat 1 located below to move on the guide rail through the safety rope, and the compression spring 2 is then compressed. With the compression of the compression spring 2, when the sliding seat 1 located above receives a pushing force from the compression spring 2 that is greater than the resistance, the sliding seat 1 located above can move along the guide rail under the action of the resultant force, so that the worker is always located between the two sliding seats 1.

[0048] In other embodiments, the power high-altitude operation construction fall arrester is further provided with an adjusting mechanism 3 configured to adjust the sensitivity of the power high-altitude operation construction fall arrester according to the horizontal distance between the worker and the guide rail, so as to make the sensitivity of the power high-altitude operation construction fall arrester higher when the horizontal distance between the worker and the guide rail is farther.

[0049] In this embodiment, the higher sensitivity means that the locking portion 11 can complete the locking at a smaller speed.

[0050] During use, the adjusting mechanism 3 can adjust the sensitivity of the electric power overhead construction fall protector according to the horizontal distance between the worker and the guide rail, so that the sensitivity of the electric power overhead construction fall protector is higher when the horizontal distance between the worker and the guide rail is farther, the protection effect is further improved, and the electric power overhead construction fall protector can be prevented from being in a high sensitivity state all the time, so as to avoid affecting the normal work of the worker.

[0051] In a further embodiment, the number of compression springs 2 is two, and the two compression springs 2 are arranged in parallel between the two sliding seats 1; the adjusting mechanism 3 is arranged to include two adjusting assemblies, the two adjusting assemblies and the compression springs 2 are arranged one by one and symmetrically; each adjusting assembly is arranged to include two sliding plates 31 and two fixed shafts 32, the two sliding plates 31 and the two fixed shafts 32 of the same adjusting assembly are symmetrically arranged on the two sliding seats 1, and the sliding plate 31 can slide along the extension direction of the guide rail; the two ends of the same compression spring 2 are fixedly connected to the two sliding plates 31 of the same adjusting assembly, and the side of the sliding plate 31 away from the compression spring 2 is provided with a guide portion 311; the fixed shaft 32 is fixedly arranged on the sliding seat 1, and the two fixed shafts 32 on the same sliding seat 1 are symmetrically arranged on the two sides of the guide rail; the adjusting ring 33 is symmetrically sleeved on each fixed shaft 32, the adjusting ring 33 can rotate, and the two adjusting rings 33 on the same fixed shaft 32 are in frictional contact with the guide rail; two sliding rings 34 are symmetrically sleeved on each fixed shaft 32, the sliding ring 34 is partially inserted into the adjusting ring 33, and a friction medium is filled between the sliding ring 34 and the adjusting ring 33; under the action of the guide portion 311, the two sliding rings 34 can synchronously and elastically slide in opposite directions along the axial direction of the fixed shaft 32 to change the contact area between the sliding ring 34 and the adjusting ring 33, and then change the resistance received by the adjusting ring 33 when rotating.

[0052] Specifically, as shown in Figure 9 , the sliding plate 31 is arranged in a flat plate structure, and is arranged to be slidingly inserted between the right side wall of the base body 101 and the left side wall of the vertical section of the mounting table 102 of the same sliding seat 1 during installation; the guide portion 311 is arranged in a V-shaped block structure; as shown in Figure 7 , the compression spring 2 is arranged in parallel with the guide rail during installation, and the top end is fixedly connected to the bottom of the sliding plate 31 located above, and the bottom end is fixedly connected to the top of the sliding plate 31 located above.

[0053] More specifically, as shown in Figure 9As shown, the fixed shaft 32 is arranged to be fixed at the left end and vertically inserted into the right side wall of the base body 101 of the same sliding seat 1, and fixed at the right end and vertically inserted into the left side wall of the vertical section of the mounting table 102 when installed; the cross-sectional shape of the adjusting ring 33 is arranged in a Z shape, and the large end of the adjusting ring 33 faces the middle part of the fixed shaft 32; in order to facilitate the limitation that the adjusting ring 33 can only rotate, two limiting rings 322 are symmetrically and spaced on the circumferential side wall of the fixed shaft 32; correspondingly, a limiting groove is formed in the inner side wall of the adjusting ring 33, and the adjusting ring 33 is arranged to be slidingly inserted into the limiting groove when installed.

[0054] More specifically, in order to limit the sliding ring 34 to only slide along the axial direction of the fixed shaft 32, Figure 9 as shown, two limiting strip groups are symmetrically and spaced on the circumferential side wall of the fixed shaft 32, each limiting strip group includes a plurality of limiting strips 321, the extending direction of the limiting strips 321 is parallel to the axial direction of the fixed shaft 32, and the plurality of limiting strips 321 in the same group are uniformly arranged in the circumferential direction; correspondingly, a sliding groove is formed in the inner circumferential wall of the sliding ring 34, the number of the sliding grooves is equal to the number of the limiting strips in the same limiting strip group, and the plurality of sliding grooves are uniformly arranged in the circumferential direction; the sliding ring 34 is arranged to be slidingly inserted into the sliding groove when installed.

[0055] More specifically, in order to realize the guiding cooperation between the guiding part 311 and the sliding ring 34, Figure 9 as shown, a sliding protrusion 341 is fixedly arranged on the outer circumferential wall of the sliding ring 34, the sliding protrusion 341 is arranged in a strip structure, and the extending direction of the sliding protrusion 341 is perpendicular to the axis of the sliding ring 34, and the bottom of the sliding protrusion 341 slidingly abuts against the inclined surface of the guiding part 311 when in use.

[0056] More specifically, the friction medium is arranged between the outer circumferential wall of the sliding ring 34 and the inner circumferential wall of the adjusting ring 33 when in use.

[0057] During use, when the worker moves away from the guide rail, the two sliding seats 1 are close to each other under the pulling of the safety rope, so as to compress the compression spring 2, the compression of the compression spring 2 makes the two sliding plates 31 of the same adjusting assembly move away from each other, and under the guiding action of the inclined surface of the guiding part 311, the two sliding rings 34 on the same fixed shaft 32 move away from each other, so as to increase the area of the sliding ring 34 inserted into the inside of the corresponding side adjusting ring 33, and then increase the friction medium contacted by the sliding ring 34 and the adjusting ring 33, and increase the resistance received by the adjusting ring 33 when rotating; when the worker falls accidentally, the sliding seat 1 can basically remain stationary under the rotating resistance of the adjusting ring 33, so as to quickly trigger the self-locking function of the fall arrestor.

[0058] Similarly, when the worker moves towards the guide rail, the two sliding plates 31 of the same adjusting assembly are close to each other under the action of the compression spring 2, and the two sliding rings 34 on the same fixed shaft 32 are close to each other under the elastic action, so as to reduce the area of the sliding ring 34 inserted into the inside of the corresponding side adjusting ring 33, and further reduce the friction medium between the sliding ring 34 and the adjusting ring 33, and reduce the resistance when the adjusting ring 33 rotates; when the worker moves normally, the sliding seat 1 can move normally, thereby reducing the possibility of triggering the self-locking function of the fall arrestor, and avoiding affecting the normal work of the worker.

[0059] In further embodiments, in order to realize the elastic sliding of the two sliding rings 34 on the same fixed shaft 32, each adjusting assembly is further provided with two second elastic members connected between the two sliding rings 34 on the same fixed shaft 32, and under the action of the second elastic member, the two sliding rings 34 on the same fixed shaft 32 have a tendency to approach each other.

[0063] In other embodiments, the friction medium is provided to include damping liquid.

[0064] In other embodiments, the electric power overhead work construction fall arrestor is further provided with two lock buckles 12, which are movably sleeved on the locking part 11 and are configured to be connected with the safety rope.

[0065] Specific to the present embodiment, the arrangement of the lock buckle 12 can improve the connection stability between the safety rope and the locking part 11.

[0066] In other embodiments, the sliding locking part is provided to include 4N auxiliary rollers 14, which are divided into two large groups, and the large groups are correspondingly arranged with the sliding seat 1, and the auxiliary rollers 14 in each large group are two by two as a small group, and the two auxiliary rollers 14 in the same small group are symmetrically arranged on both sides of the guide rail and are in frictional contact with the guide rail; N is a natural number greater than or equal to 1.

In order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not contradict, they shall be considered as the scope of the present disclosure.

[0069] The above embodiments only express several implementation manners of the present application, the description is relatively specific and detailed, but it shall not be understood as the limitation of the scope of the present application. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
