Description

Technical Field

[0001] The invention relates to the technical field of electric power operation, in particular to a fall arrester for electric power high-altitude operation construction. Background Art

[0002] A fall arrester is a safety device used to prevent people or objects from falling during high-altitude operations. It is usually called a speed differential or a self-controlled fall arrester. Its main function is to induce braking through speed changes when a fall occurs, thereby effectively protecting the safety of the user.

[0003] Commonly used fall arresters include flexible fall arresters and rigid fall arresters. The flexible fall arrester is made of flexible materials such as stainless steel stranded wire, steel-core aluminum stranded wire or galvanized steel stranded wire. This device is more flexible and can effectively buffer the impact force generated during a fall, thereby reducing damage to the user. The rigid fall arrester, also known as the hard fall arrester, is usually made of rigid materials such as steel rails. It has high stability and fixity and is suitable for high-altitude working environments that require high stability, such as construction, steel, and shipbuilding.

[0004] In the related technology, for example, Chinese patent CN118341013A discloses a rigid guide rail type fall prevention device. When the rigid guide rail type fall prevention device is in use, the worker needs to pull the fall arrester to move on the rigid guide rail body when moving on the operating platform, so as to facilitate mobile construction and keep 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 support block through the first ring and the second ring, so that the lower support block swings through the circular sleeve, and when the lower support block swings, it will drive the slider to slide into the interior of the first air cavity through the rotating bar, so that the gas inside the first air cavity enters the interior of the second air cavity through the first gas delivery channel and the second gas delivery channel, and the pressure block slides outward and is squeezed and fits on the rigid guide rail body to achieve double self-locking.

[0005] Although the above-mentioned rigid guide rail type fall arrester can improve the protection effect to a certain extent, it is found in actual use that when workers are working at height, the fall arrester is below and the workers are above, which causes the workers to drop a certain distance when falling to trigger the self-locking function of the fall arrester. The workers may collide with surrounding objects during the falling process, which can easily cause safety accidents; and because the workers have fallen a certain distance, the workers themselves have a large kinetic energy, which will increase the instantaneous force on the fall arrester and reduce its service life on the one hand, and cause greater damage to the workers on the other hand. Summary of the invention

[0006] Based on this, it is necessary to provide a kind of electric power high-altitude construction fall arrester to address the problem of poor reliability of the current fall arrester during use.

[0007] The above purpose is achieved through the following technical solutions: A fall arrester for electric power aerial work construction, used to lock the worker on a guide rail when the worker falls; the fall arrester for electric power aerial work construction comprises: Two slides are both sleeved on the guide rail and 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 the two slides can slide relative to each other; each of the slides is elastically hinged with a locking portion, and the locking portion is configured to be connected to a safety rope on the worker, and is configured to have a moving state and a locking state, when in the moving state, the locking portion is disengaged from the guide rail; when in the locking state, the locking portion and the guide rail are frictionally locked; each of the slides is provided with a sliding locking portion, and the sliding locking portion is configured to lock the position of the slide on the guide rail.

[0009] Furthermore, the first elastic member includes a compression spring.

[0010] Furthermore, the electric power high-altitude construction fall arrester also includes an adjustment mechanism, which is configured to adjust the sensitivity of the electric power high-altitude construction fall arrester according to the horizontal distance between the worker and the guide rail, thereby making the sensitivity of the electric power high-altitude construction fall arrester higher when the horizontal distance between the worker and the guide rail is greater.

[0011] Furthermore, there are two compression springs, which are arranged in parallel between the two slide seats; the adjustment mechanism includes two adjustment components, and the two adjustment components and the compression springs are arranged in one-to-one correspondence and symmetrically; each of the adjustment components includes two sliding plates and two fixed shafts, and the two sliding plates and two fixed shafts of the same adjustment component are symmetrically arranged on the two slide seats, and the sliding plate can slide along the extension direction of the guide rail; the two ends of the same compression spring are respectively fixedly connected to the two sliding plates of the same adjustment component, and a guide portion is arranged on the side of the sliding plate facing away from the compression spring; the fixed shaft is fixedly arranged on the slide seat, and the same The two fixed shafts on each of the slide seats are symmetrically arranged on both sides of the guide rail; an adjusting ring is symmetrically sleeved on each of the fixed shafts, and the adjusting ring can rotate on its own, and the two adjusting rings on the same fixed shaft are in friction contact with the guide rail; two sliding rings are symmetrically sleeved on each of the fixed shafts, and the sliding rings are partially inserted inside the adjusting rings at the same time, and a friction medium is filled between the sliding rings and the adjusting rings; under the action of the guide part, the two sliding rings can synchronously slide elastically in opposite directions along the axial direction of the fixed shaft to change the contact area between the sliding ring and the adjusting ring, thereby changing the resistance encountered by the adjusting ring when it rotates.

[0012] Furthermore, each of the adjustment components also includes two second elastic members, and the second elastic members are connected between two sliding rings on the same fixed shaft. Under the action of the second elastic members, the two sliding rings on the same fixed shaft tend to approach each other.

[0013] Furthermore, the second elastic member includes a second tension spring.

[0014] Furthermore, the friction medium includes damping fluid.

[0015] Furthermore, the electric power aerial work construction fall arrester also includes two lock buckles, which are movably sleeved on the locking portion and are configured to be connectable to the safety rope.

[0016] Furthermore, the sliding locking portion includes 4N auxiliary rollers, and the 4N auxiliary rollers are divided into two large groups. The large groups and the sliding seats are arranged correspondingly, and the auxiliary rollers in each large group are formed into a small group in pairs. The two auxiliary rollers in the same small group are symmetrically arranged on both sides of the guide rail and are in friction contact with the guide rail; N is a natural number greater than or equal to 1.

[0023] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0024] like Figures 1 to 9As shown, the electric power high-altitude construction fall arrester provided by an embodiment of the present invention is used to lock the worker on the guide rail when the worker falls, and is configured to include two slides 1, the two slides 1 are both sleeved on the guide rail, and 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 the two slides 1 can slide relative to each other; each slide 1 is elastically hinged with a locking portion 11, the locking portion 11 is configured to be connected to the safety rope on the worker, and is configured to have a moving state and a locking state, when in the moving state, the locking portion 11 is disengaged from the guide rail; when in the locked state, the locking portion 11 and the guide rail are frictionally locked; each slide 1 is provided with a sliding locking portion, and the sliding locking portion is configured to lock the position of the slide 1 on the guide rail.

[0025] Specifically in this embodiment, Figure 2 As shown, the slide 1 is configured to consist of a base 101 and two mounting platforms 102, wherein the base 101 is configured to be a rectangular block structure, the mounting platform 102 is configured to be a T-shaped block structure, and has a horizontal section and a vertical section that are vertically and fixedly connected, and the mounting platform 102 is configured when installed so that the left end of the horizontal section is fixed and vertically connected to the right side wall of the base 101, and the two mounting platforms 102 are symmetrically arranged; when in use, the guide rail passes between the two mounting platforms 102 on the same slide 1.

[0026] like Figure 4 As shown, the locking portion 11 is configured as an L-shaped block structure, and the inflection point of the locking portion 11 is hinged on the base 101; to facilitate the installation of the locking portion 11, mounting holes are opened through the left and right side walls of the base 101, and a rotating shaft is vertically connected to the front and rear side walls of the mounting holes. When installing, the locking portion 11 is configured so that its inflection point can be rotatably sleeved on the rotating shaft.

[0027] More specifically, in order to facilitate the elastic hinge connection of the locking portion 11, as shown in FIG. Figure 4 As shown, a first tension spring 13 is connected between the left side wall at the right end of the locking portion 11 and the slide seat 1 , and under the action of the first tension spring 13 , the locking portion 11 has a tendency to rotate clockwise around the rotation axis.

[0028] When in use, firstly, the two slides 1 are sleeved on the guide rails, and then the safety ropes on the workers are connected to the two locking parts 11 respectively. When the workers move in the vertical direction on the operating platform, they can drive the slide 1 located below to move on the guide rails through the safety ropes, and the slide 1 located below then drives the slide 1 located above to move on the guide rails, so that the workers are always located between the two slides 1. In the process of the slide 1 moving, if Figure 4As shown, the locking portion 11 is in a moving state and away from the guide rail, thereby avoiding frictional contact between the locking portion 11 and the guide rail to affect the movement of the slide 1. Under the action of the sliding locking portion, the slide 1 can be locked on the guide rail to avoid falling. When a worker falls accidentally, since the locking portion 11 located above is above the worker, the worker can trigger the self-locking function of the fall arrester by descending a short distance, thereby avoiding damage to the fall arrester and the worker caused by excessive kinetic energy when the worker falls. During the worker's fall, the worker drives the locking portion 11 to rotate around the rotation axis in the counterclockwise direction through the safety rope on his body, so that the locking portion 11 switches from the moving state to the locked state. Figure 5 As shown, the locking portion 11 is in a locked state and is frictionally locked with the guide rail; and when the locking portion 11 located at the top fails, the locking portion 11 located at the bottom can still trigger the self-locking function of the fall arrester, thereby achieving double insurance.

[0029] In some embodiments, the electric power aerial work construction fall arrester is configured to also include a first elastic member, which is connected between the two slides 1. Under the action of the first elastic member, the two slides 1 tend to move away from each other.

[0030] When in use, the slide 1 located at the bottom can drive the slide 1 located at the top to move along the guide rail through the first elastic member, so that the worker is always located between the two slides 1.

[0031] In a further embodiment, the first elastic member is configured to include a compression spring 2 .

[0032] Specifically in this embodiment, the compression spring 2 is arranged during installation so that the top end is connected to the bottom of the upper slide 1 and the bottom end is connected to the top of the lower slide 1 .

[0033] During use, when the worker moves in the vertical direction on the operating platform, he can drive the slide 1 located below to move on the guide rail through the safety rope, and the compression spring 2 is subsequently compressed; as the compression spring 2 is compressed, when the thrust received by the compression spring 2 on the slide 1 located above is greater than the resistance it receives, the slide 1 located above can move along the guide rail under the action of the combined force, so that the worker is always located between the two slides 1.

[0034] In other embodiments, the electric power high-altitude construction fall arrester is configured to also include an adjusting mechanism 3, and the adjusting mechanism 3 is configured to be able to adjust the sensitivity of the electric power high-altitude construction fall arrester according to the horizontal distance between the worker and the guide rail, thereby making the sensitivity of the electric power high-altitude construction fall arrester higher when the horizontal distance between the worker and the guide rail is greater.

[0035] Specifically in this embodiment, a higher sensitivity means that the locking portion 11 can complete locking at a lower speed.

[0036] During use, the adjustment mechanism 3 can adjust the sensitivity of the electric power high-altitude construction fall arrester according to the horizontal distance between the worker and the guide rail, so that the sensitivity of the electric power high-altitude construction fall arrester is higher when the horizontal distance between the worker and the guide rail is greater, thereby further improving the protection effect and avoiding the electric power high-altitude construction fall arrester being in a highly sensitive state all the time, thereby avoiding affecting the normal construction work of the workers.

[0037] In a further embodiment, there are two compression springs 2, which are arranged in parallel between the two slides 1; the adjustment mechanism 3 is arranged to include two adjustment components, and the two adjustment components and the compression springs 2 are arranged one by one and symmetrically; each adjustment component is arranged to include two sliding plates 31 and two fixed shafts 32, and the two sliding plates 31 and two fixed shafts 32 of the same adjustment component are symmetrically arranged on the two slides 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 respectively fixedly connected to the two sliding plates 31 of the same adjustment component, and a guide portion 311 is arranged on the side of the sliding plate 31 facing away from the compression spring 2; the fixed shaft 32 is fixedly arranged on the slide 1, The two fixed shafts 32 on the same slide seat 1 are symmetrically arranged on both sides of the guide rail; each fixed shaft 32 is symmetrically sleeved with an adjusting ring 33, the adjusting ring 33 can rotate on its own, and the two adjusting rings 33 on the same fixed shaft 32 are in friction contact with the guide rail; each fixed shaft 32 is symmetrically sleeved with two sliding rings 34, the sliding ring 34 is partially inserted into the adjusting ring 33 at the same time, and a friction medium is filled between the sliding ring 34 and the adjusting ring 33; under the action of the guide part 311, the two sliding rings 34 can synchronously 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, thereby changing the resistance encountered by the adjusting ring 33 when rotating.

[0038] Specifically in this embodiment, Fig. 9 As shown, the sliding plate 31 is configured as a flat plate structure, and is configured to be slidably inserted between the right side wall of the base 101 of the same slide seat 1 and the left side wall of the vertical section of the mounting platform 102 during installation; the guide portion 311 is configured as a V-shaped block structure; Figure 7 As shown, the compression spring 2 is arranged to be parallel to 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.

[0039] More specifically, Fig. 9As shown, the fixed shaft 32 is arranged to be fixed at the left end and vertically inserted on the right side wall of the base 101 of the same slide seat 1, and the right end is fixed and vertically inserted on the left side wall of the vertical section of the mounting platform 102 during installation; the cross-sectional shape of the adjusting ring 33 is arranged to be Z-shaped, and the large mouth end of the adjusting ring 33 faces the middle part of the fixed shaft 32; in order to facilitate limiting the adjusting ring 33 to be able to rotate only on its own, two limiting rings 322 are symmetrically and spaced apart on the circumferential side wall of the fixed shaft 32; accordingly, an annular limiting groove is opened on the inner side wall of the adjusting ring 33, and the adjusting ring 33 is arranged to be slidably inserted in the limiting groove during installation.

[0040] More specifically, in order to limit the sliding ring 34 to slide only along the axial direction of the fixed shaft 32, as shown in FIG. Fig. 9 As shown, two limit bar groups are symmetrically and spaced apart on the circumferential side wall of the fixed shaft 32, each limit bar group includes a plurality of limit bars 321, the extension direction of the limit bars 321 is parallel to the axial direction of the fixed shaft 32, and the plurality of limit bars 321 of the same group are evenly arranged along the circumferential direction; correspondingly, sliding grooves having a number equal to the number of limit tubes of the same limit bar group are opened on the inner circumferential wall of the sliding ring 34, and the plurality of sliding grooves are evenly arranged along the circumferential direction, and the sliding ring 34 is configured so that the limit bars 321 are slidably inserted into the sliding grooves during installation.

[0041] More specifically, in order to facilitate the guide cooperation between the guide portion 311 and the sliding ring 34, as shown in FIG. Fig. 9 As shown, a sliding protrusion 341 is fixedly provided on the outer peripheral wall of the sliding ring 34. The sliding protrusion 341 is provided as a strip structure, and its extension direction is perpendicular to the axis of the sliding ring 34. When in use, the bottom of the sliding protrusion 341 slides against the inclined surface of the guide part 311.

[0042] More specifically, the friction medium is arranged to be coated between the outer peripheral wall of the sliding ring 34 and the inner peripheral wall of the adjusting ring 33 when in use.

[0043] During use, when the worker moves away from the guide rail, the two slide seats 1 approach each other under the pull of the safety rope, thereby compressing the compression spring 2. The compression of the compression spring 2 causes the two sliding plates 31 of the same adjustment component to move away from each other. Under the inclined guiding action of the guide portion 311, the two sliding rings 34 on the same fixed shaft 32 move away from each other, thereby increasing the area of ​​the sliding ring 34 inserted into the corresponding side adjustment ring 33, thereby increasing the friction medium in contact with the sliding ring 34 and the adjustment ring 33, and increasing the resistance encountered by the adjustment ring 33 when rotating; when the worker falls accidentally later, the slide seat 1 can basically remain motionless under the rotation resistance of the adjustment ring 33, thereby quickly triggering the self-locking function of the fall arrester.

[0044] Similarly, when the worker moves toward the guide rail, the two sliding plates 31 of the same adjustment component approach each other under the action of the compression spring 2, and the two sliding rings 34 on the same fixed shaft 32 approach each other under the action of elasticity, thereby reducing the area of ​​the sliding ring 34 inserted into the corresponding side adjustment ring 33, thereby reducing the friction medium in contact with the sliding ring 34 and the adjustment ring 33, and reducing the resistance encountered by the adjustment ring 33 when rotating; when the worker moves normally afterwards, the slide seat 1 can move normally, thereby reducing the possibility of triggering the self-locking function of the fall arrester and avoiding affecting the normal construction work of the workers.

[0045] In a further embodiment, in order to facilitate the elastic sliding of the two sliding rings 34 on the same fixed shaft 32, each adjustment component is configured to also include two second elastic members, and the second elastic members are connected between the two sliding rings 34 on the same fixed shaft 32. Under the action of the second elastic members, the two sliding rings 34 on the same fixed shaft 32 have a tendency to approach each other.

[0046] During use, the second elastic member enables the sliding ring 34 to be normally reset to avoid affecting the next use.

[0047] In a further embodiment, the second elastic member is configured to include a second tension spring 35 .

[0048] Specifically in this embodiment, Fig. 9 As shown, the second tension spring 35 is arranged during installation with the left end fixedly connected to the right side wall of the left sliding protrusion 341, and the right end fixedly connected to the left side wall of the right sliding protrusion 341. Under the action of the second tension spring 35, the two sliding rings 34 on the same fixed shaft 32 tend to approach each other.

[0049] In other embodiments, the friction medium is configured to include a damping fluid.

[0050] In other embodiments, the electric power aerial work construction fall arrester is configured to further include two lock buckles 12, which are movably sleeved on the locking portion 11 and are configured to be connected to a safety rope.

[0051] Specifically in this embodiment, the provision of the lock buckle 12 can improve the connection stability between the safety rope and the locking portion 11 .

[0052] In other embodiments, the sliding locking portion is configured to include 4N auxiliary rollers 14, and the 4N auxiliary rollers 14 are divided into two large groups. The large groups are arranged corresponding to the slide seat 1, and the auxiliary rollers 14 in each large group are formed into a small group in pairs. The two auxiliary rollers 14 in the same small group are symmetrically arranged on both sides of the guide rail and are in friction contact with the guide rail; N is a natural number greater than or equal to 1.

[0053] Specifically in this embodiment, for example, the number of auxiliary rollers 14 is four. Figure 2 and Figure 4 As shown, when installing, the left end of the auxiliary roller 14 is vertically and rotatably inserted into the right side wall of the base 101, and the right end is vertically and rotatably inserted into the left side wall of the vertical section of the mounting platform 102; and the axes of the two auxiliary rollers 14 on the same slide 1 are located in the same horizontal plane and frictionally abut against both sides of the guide rail to lock the position of the slide 1 on the guide rail.

[0054] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
