Abstract
Description
Technical Field
[0001] This invention relates to the technical field of safety protection for working at heights, and in particular to a non-invasive horizontal lifeline device and method for working at heights in a GIS room. Background Technology
[0002] Currently, in high-altitude operations in the power industry, there are common horizontal lifeline or safety rope solutions. These solutions are typically used in scenarios such as building exterior wall construction and large steel structure installation. Moreover, these solutions mostly rely on pre-embedded anchor points, complex tracks, or permanent installation structures that require welding / drilling, and cannot prevent workers at height from accidentally entering non-working areas.
[0003] However, the aforementioned existing technologies are completely unsuitable for the unique environment of a GIS (Gas Insulated Switchgear) room, resulting in a long-standing safety dilemma of "no reliable anchor points" for high-altitude operations in GIS rooms. The specific dilemma lies in: Because the GIS equipment inside the GIS room has a smooth cylindrical structure, it cannot be used as a safety belt attachment point. Furthermore, since there are no other fixed structures at higher levels inside the room for attachment, conventional methods of fixing with steel wire ropes are not suitable for the GIS room. Secondly, maintenance work is a temporary requirement, and no destructive modifications (such as drilling or welding) to the main load-bearing structure of the GIS room (such as beams) are allowed. Therefore, there is a high risk of working at height.
[0004] In addition, the equipment layout in the GIS room is relatively compact, and generally only a fence is set up at the ground level to distinguish between the work area and the non-work area. When workers are working at height, it is difficult for them to identify the boundary between the work area and the non-work area at height, and there is a possibility of accidentally entering the non-work area.
[0005] Therefore, based on the above-mentioned technical problems, this application proposes a non-invasive horizontal lifeline device and method for high-altitude operations in GIS rooms that does not require damage to the GIS room, has good security, and can distinguish between working and non-working areas for staff. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a non-invasive horizontal lifeline device and method for high-altitude operations in GIS rooms that does not require damage to the GIS room, has good safety, and can distinguish between working and non-working areas for staff.
[0007] To achieve the above objectives, the present invention provides a non-intrusive horizontal lifeline device for high-altitude operations in a GIS room, comprising a steel wire rope, boundary warning components, a safety belt, and an alarm. At least two boundary warning components are configured, detachably and spaced apart, to divide the steel wire rope between the two boundary warning components into a working area, and the steel wire rope outside the two boundary warning components into a non-working area. The safety belt has a first attachment end for attaching to the working area of the steel wire rope. The alarm is located at the first attachment end of the safety belt and is used to issue a warning signal when the first attachment end contacts any boundary warning component, or when the distance between the first attachment end and any boundary warning component is less than a preset distance threshold.
[0008] Furthermore, the device also includes a wire locking device, of which at least two are provided. The wire locking device is used to wrap around and fix the end of the wire rope to the wire rope to form a closed rope loop structure that fixes the wire rope to the crossbeam.
[0009] Furthermore, the wire locking device is a dual-hole wire locking device.
[0010] Furthermore, the boundary warning component includes a magnetic coded marker ring and a fixing unit. The magnetic coded marker ring is disposed on the fixing unit and is used to trigger the alarm function of the alarm. The fixing unit is detachably fixed to the wire rope.
[0011] Furthermore, the steel wire rope is made of high-strength galvanized material.
[0012] Furthermore, the length of the steel wire rope is greater than the width of the GIS room.
[0013] Furthermore, the diameter of the wire rope is greater than or equal to 12mm.
[0014] Furthermore, a fall protection buffer is provided at one end of the seat belt, which is used to absorb the impact energy generated by the fall.
[0015] Based on the same inventive concept, this application also provides a non-invasive horizontal lifeline method for high-altitude operations in a GIS room, comprising the following steps: Step 1: Measure the indoor data of the GIS room, wherein the indoor data includes the movable range of the work area and the width data between the beams at the height of the work area; Step 2: Based on the width data between the beams at the indoor height, select the steel wire rope with the corresponding length, and divide the working area of the steel wire rope according to the movable range of the working area; Step 3: After passing one end of the wire rope through one of the locking devices, it is wrapped around one of the crossbeams at a high point in the working area. Then, the end of the wire rope that has been wrapped is folded back and passed through the locking device. Then, the locking device is used to fix the folded-back part of the wire rope and the overlapping part corresponding to the folded-back part by a preset fixing tool. Step 4: After one end of the wire rope is fixedly wrapped around one of the crossbeams, the wire rope is pulled taut to a horizontal state, and the two boundary warning components are detachably installed on the boundary of the working area of the wire rope. Step 5: Repeat step 3 to fix the other end of the wire rope around another beam opposite to one of the beams mentioned above. When the wire rope is fixed around the beam, it must be taut. Step 6: After the steel wire rope is fixed, the first hook end of the safety belt is movably hooked onto the working area of the steel wire rope, and the second hook end of the safety belt is connected to the worker's protective suit. After the connection of the two ends of the safety belt is completed, the worker is allowed to carry out maintenance work within the permitted range of movement in the working area. When the first hook end of the safety belt comes into contact with any boundary warning group or the distance between the first hook end and any boundary warning component is less than a preset distance threshold, a warning signal is issued.
[0016] Furthermore, in step 6, after the wire rope is fixed, its height above the ground is greater than the height above the ground of the worker.
[0017] The present invention adopts the above-described solution, and its beneficial effects are as follows: By wrapping the two ends of the steel wire rope around two opposing crossbeams at a high point inside the GIS room, a flexible and non-invasive fixation is achieved without the need for pre-embedded anchor points in the wall or on-site drilling. This allows for safe high-altitude maintenance within the GIS room, where destructive construction is prohibited, and features rapid deployment. Secondly, the steel wire rope and locking device can be recycled after use, resulting in low operating costs and no impact on the layout of the GIS room. Furthermore, by installing two boundary warning components on the steel wire rope, an alarm on the safety belt will issue a warning signal when workers approach non-working areas, effectively dividing the work area from the non-working area (work zone and non-working zone) at high altitude, thus providing a clear warning to workers operating at height and improving safety.

[0022] To facilitate understanding of the present invention, a more complete description is given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention. Example
[0023] See appendix Figure 1-2 As shown, in this embodiment, a non-intrusive horizontal lifeline device for high-altitude operations in a GIS room includes a steel wire rope 1, a boundary warning component 2, a safety belt 3, a wire locking device 5, and an alarm 4. At least two boundary warning components 2 are configured, and each component is detachably and spaced apart from the steel wire rope 1 to divide the steel wire rope 1 between the two boundary warning components 2 into a working area, and the steel wire rope 1 outside the two boundary warning components 2 into a non-working area (the specific size of the aforementioned areas needs to be set according to actual conditions). Secondly, at least two wire locking devices 5 are provided. These devices are used to wrap around and fix the end of the steel wire rope 1 to the steel wire rope 1, forming a closed loop structure that fixes the steel wire rope 1 to the crossbeam, thereby allowing the steel wire rope 1 to be erected between two crossbeams arranged opposite each other at a high altitude within the GIS room.
[0024] Furthermore, the wire locking device 5 is preferably a double-hole wire locking device 5. By selecting the double-hole wire locking device 5, sufficient threading space can be provided for the setting of threading and then turning back at the end of the wire rope 1 (that is, the wire rope 1 uses one hole when threading for the first time and the other hole when turning back). And with the pre-set fixing tool, the turning back part and the overlapping part corresponding to the turning back part are effectively fixed (the above-mentioned double-hole wire locking device 5 includes the wire locking device 5 body and two clamping bolts. After the wire rope 1 is threaded, the clamping bolts are screwed into the corresponding holes by tools such as wrenches or pneumatic wrenches to clamp the wire rope 1, thereby achieving fixation; the wire locking device 5 body and the two clamping bolts are not shown in the figure).
[0025] It should be noted that, since the GIS equipment itself is a smooth cylindrical structure, it cannot be used as a safety belt attachment point. Furthermore, since there are no other fixed structures available for attachment at higher levels indoors, the conventional method of fixing with steel wire ropes is not suitable for the GIS room. Secondly, maintenance work is a temporary requirement, and no destructive modifications (such as drilling or welding) are allowed to be made to the main load-bearing structure of the GIS room (such as beams). Therefore, there is a disadvantage of high-altitude operation.
[0026] In this embodiment, by adopting a flexible and non-invasive fixing method, the steel wire rope 1 and the locking device 5 are used to form a rope loop structure around the beam at both ends of the steel wire rope 1. Without the need for anchor points pre-embedded in the wall or on-site drilling, safe high-altitude maintenance can be carried out in the GIS room where destructive construction is prohibited, achieving the purpose of rapid deployment. Specifically, it has the characteristics of low operation threshold and rapid deployment. Secondly, the steel wire rope 1 and the locking device 5 can be recycled after use, which has the characteristics of low use cost and no impact on the layout of the GIS room.
[0027] In this embodiment, the safety belt 3 has a first attachment end for attaching to the working area of the wire rope 1, and its second attachment end is connected to the worker's protective suit; the alarm 4 is set at the first attachment end of the safety belt 3, and is used to issue a warning signal when the first attachment end comes into contact with any boundary warning component 2, or when the distance between the first attachment end and any boundary warning component 2 is less than a preset distance threshold, so as to warn the worker that he is about to leave the working area (too close to the non-working area may be dangerous). The warning signal can be issued by a highly indicative method such as emitting a buzzer or flashing a warning light.
[0028] It should be noted that, due to the compact layout of equipment in the GIS room, fences are generally only installed at the ground level to distinguish between the work area and the non-work area. However, when workers are performing tasks at height, it is difficult to identify the boundaries between the work area and the non-work area, which may lead to accidental entry into the non-work area, posing a high risk. In this embodiment, a steel wire rope 1 is installed between two beams arranged opposite each other at a high position in the GIS room, and two boundary warning components 2 are installed on the steel wire rope 1. When workers approach the non-work area, an alarm 4 on the safety belt 3 emits a warning signal, thereby achieving the high-altitude division of the work area and the non-work area (work zone and non-work zone), providing a clear warning to workers performing tasks at height and improving their safety. Secondly, by keeping the steel wire rope 1 taut, the rope 1 is prevented from falling due to its own weight, thus ensuring the safety of the device and preventing the actual working area from deviating from the preset range.
[0029] Furthermore, the steel wire rope 1 is made of high-strength galvanized material, and the diameter of the steel wire rope 1 is greater than or equal to 12mm, thereby ensuring that the steel wire rope 1 has sufficient support strength and preventing the steel wire rope 1 from breaking due to insufficient strength and inability to withstand excessive impact force when falling from a height, thus improving the protection level of the device for workers.
[0030] Furthermore, the length of the wire rope 1 is greater than the width of the GIS room (the specific length of the wire rope 1 needs to be measured according to the actual working area) so as to leave enough space for both ends of the wire rope 1 to be wrapped around the high crossbeam, avoiding the phenomenon that after one end of the wire rope 1 is wrapped and fixed, the other end cannot be wrapped and fixed properly, thus ensuring that the device can be used normally.
[0031] Furthermore, the boundary warning component 2 includes a magnetic coded marking ring and a fixing unit. The magnetic coded marking ring is set on the fixing unit and is used to trigger the alarm function of the alarm 4. The fixing unit is detachably fixed to the wire rope 1. The fixing unit can be detachably fixed by means of clamping, magnetic attraction, etc. (the specific structure and fixing method can be set according to the actual situation, and no specific restrictions are made here).
[0032] Furthermore, a fall protection buffer (not shown in the figure) is also provided at one end of the safety belt 3. The fall protection buffer is used to absorb the impact energy generated by the fall, that is, to protect the staff in the event of a fall from a height (the above-mentioned fall protection buffer needs to be specifically selected according to the usage scenario and the specific physical data of the staff. Its structure and usage method are easy to understand by those skilled in the art, and will not be elaborated here). Specifically, since the work area inside the GIS room may be located at a high position and a large height above the ground, if only a single safety belt 3 is used when the staff is performing maintenance, the excessive impact may exceed the strength limit of the safety belt 3 and cause it to break when a fall from a height occurs, thus failing to provide safety protection for the staff. By setting up the above-mentioned fall protection buffer, the impact force of the fall can be effectively absorbed in the event of a fall from a height, and the injury to the staff can be reduced through the buffering effect, thereby providing safety protection for the staff and improving the safety of the equipment. Example
[0033] See appendix Figure 3 As shown, a non-invasive horizontal lifeline method for high-altitude operations in a GIS room includes the following steps: Step 1: Measure the indoor data of the GIS room, including the movable range of the work area and the width data between the beams at the height of the work area, to ensure that the corresponding size of the steel wire rope 1 can be selected and the specific layout of the steel wire rope 1 can be determined, so as to ensure the normal use of the above-mentioned device. Step 2: Based on the width data between the beams at the indoor height, select the steel wire rope 1 with the corresponding length, and divide the working area of the steel wire rope 1 according to the movable range of the working area; Step 3: After passing one end of the wire rope 1 through one of the locking devices 5, it is wrapped around one of the crossbeams at the height of the work area, and the end of the wire rope 1 that has completed the wrapping is folded back and passed through the locking device 5. Then, by using a preset fixing tool (such as a wrench), the locking device 5 fixes the folded-back part of the wire rope 1 and the overlapping part corresponding to the folded-back part. Step 4: After one end of the wire rope 1 is fixed and wrapped around one of the crossbeams, the wire rope 1 is pulled taut to a horizontal state, and the two boundary warning components 2 are detachably installed on the boundary of the working area of the wire rope 1. Step 5: Repeat step 3, and fix the other end of the steel wire rope 1 around the other beam opposite to one of the above beams. After the steel wire rope 1 is fixed around the beam, the steel wire rope 1 should be taut, that is, the steel wire rope 1 should be in a relatively horizontal state. This makes it easier for the alarm 4 to detect the distance to any boundary warning component 2, avoids misjudgment caused by the working area of the steel wire rope 1 being relatively reduced due to drooping, and improves the effectiveness and safety of the device. Step 6: After the wire rope 1 is fixed, the first hook end of the safety belt 3 is movably hooked onto the working area of the wire rope 1, and the second hook end of the safety belt 3 is connected to the worker's protective suit. After the connection of both ends of the safety belt 3 is completed, the worker is allowed to carry out maintenance work within the permitted range of movement in the working area. When the first hook end of the safety belt 3 comes into contact with any boundary warning component 2 or the distance between the first hook end and any boundary warning component 2 is less than a preset distance threshold (this preset distance threshold can be set according to the actual situation), the alarm 4 on the first hook end of the safety belt 3 will issue a warning signal to alert the worker to the current position and avoid the danger caused by accidentally entering a non-working area.
[0034] Furthermore, in step 6, after the wire rope 1 is fixed, its height above the ground is greater than that of the worker, in order to comply with the safety principle of "high attachment, low use" for working at heights. This reduces the impact on the safety belt 3 in the event of a fall from height, thus improving safety. Secondly, the fixed wire rope 1 can be used by one or more workers for mobile attachment, that is, the wire rope 1 erected between two relatively arranged crossbeams can be used as a shared mobile attachment point. At the same time, according to actual maintenance needs, one or more workers can use the same device for maintenance at heights, providing continuous safety protection for multiple workers, thus having a wide range of applicability.
[0035] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any modifications or variations made by those skilled in the art, without departing from the scope of the present invention, using the disclosed technical content, are equivalent embodiments of the present invention. Therefore, all equivalent changes made based on the concept of the present invention without departing from the scope of the present invention should be covered within the protection scope of the present invention.
