Description

Technical Field

[0001] This application belongs to the field of power construction technology, and in particular relates to a fall protection device for power construction. Background Technology

[0002] Power construction refers to a series of engineering operations carried out for the construction, maintenance, and repair of power systems. It covers the installation, commissioning, inspection, and emergency repair of power generation facilities, transmission lines, and distribution equipment, such as high-voltage line erection, substation equipment installation, and cable laying. When power construction involves working at heights, such as connecting lines or repairing equipment on poles, scaffolding, building roofs, or high-altitude platforms, fall protection devices must be used to prevent workers from falling due to accidental falls or tool failures. Common examples include safety belts, safety ropes, fall arrestors, and lifeline systems to ensure the personal safety of construction workers.

[0003] The existing utility model with authorization announcement number CN223164292U discloses a fall protection device for power construction. By setting tightening bolts and locking parts, the connection end of the upper fixed frame and the lower fixed frame can be quickly tightened and fixed, which is convenient for installation and disassembly. By setting sliding rods and auxiliary plates, the stability of the clamping plate during movement and clamping can be enhanced, avoiding unstable clamping and thus preventing accidents.

[0004] While the above technical solution facilitates installation and disassembly to some extent, it requires loosening the clamping structure each time the relative clamped safety cable structure moves upward. It lacks a convenient locking structure that allows the device to move upward along the safety cable, causing construction workers to loosen the device multiple times each time it needs to be moved upward. After the device is loosened, its anti-fall function will fail, leaving construction workers still at risk of falling.

[0005] Therefore, we propose a fall protection device for power construction to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that the anti-fall function of the device will fail after the device is loosened, so that construction workers will still be at risk of falling. Therefore, this invention proposes an anti-fall device for power construction.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A fall arrestor for power construction includes a first casing, a second casing disposed on the outer side of the first casing, a fixing rod fixedly connected to the inner wall of the first casing, a connecting block fixedly connected to the inner side wall of the first casing, a first arc-shaped clamping block fixedly connected to the inner wall of the connecting block, a support rod fixedly connected to the inner wall of the second casing, a knocking rod disposed inside the second casing, a second arc-shaped clamping block disposed on the outer side of the first arc-shaped clamping block, a support frame fixedly connected to the outer surface of the second arc-shaped clamping block, and a hanging ring fixedly connected to the end of the knocking rod away from the support frame.

[0009] Preferably, the inner wall of the second casing is rotatably connected to the outer surface of the fixing rod, the inner wall of the striking rod is rotatably connected to the outer surface of the support rod, the outer surface of the support frame is rotatably connected to the inner wall of the striking rod, and fastening bolts are provided in both the interior of the first casing and the interior of the second casing, with the outer surfaces of the fastening bolts contacting the inner walls of the first casing and the second casing respectively.

[0010] Preferably, the outer surface of the fastening bolt is threaded with a fastening nut, and the end of the fastening nut near the first casing is in contact with the outer surface of the first casing.

[0011] Preferably, a washer is fitted on the outer surface of the fastening bolt, and the side of the washer near the second casing is in contact with the outer surface of the second casing.

[0012] Preferably, the inner wall of the first arc-shaped clamping block is fixedly connected to a first anti-slip sleeve, and the inner wall of the first anti-slip sleeve is provided with a plurality of identical first anti-slip grooves.

[0013] Preferably, the inner wall of the second arc-shaped clamping block is fixedly connected to a second anti-slip sleeve, and the inner wall of the second anti-slip sleeve is provided with a plurality of identical second anti-slip grooves.

[0014] In summary, the technical effects and advantages of this application are as follows:

[0015] The main structure is formed by the cooperation of the first and second shells. The fixing rod on the inner wall of the first shell enhances the stability of the overall structure when opening and closing. The first arc-shaped clamping block, fixed on its inner wall by the connecting block, forms a clamping base for the safety cable with the second arc-shaped clamping block on the outer side. The support rod on the inner wall of the second shell provides rotational support for the knocking rod. The knocking rod is connected to the second arc-shaped clamping block through the support frame, and the position of the second arc-shaped clamping block can be adjusted by lever action, facilitating the movement of the device along the safety cable. Position adjustment can be achieved without loosening the overall structure, preventing the fall protection function from failing during movement. The hanging ring at the end of the knocking rod facilitates the connection of safety equipment for construction personnel, thus enabling the device to move along the safety cable. During ascent, the first and second arc-shaped clamps will not over-clamp the cable between them. However, in the event of a fall, the first and second arc-shaped clamps will quickly clamp and lock the cable between them. The overall structure ensures clamping stability and fall protection while significantly improving ease of use and reducing the risk of falls for construction workers working at heights. It avoids the problem of construction workers having to loosen the device multiple times each time they need to move it upwards due to the lack of a convenient locking structure that allows the device to move upwards along the safety cable. After loosening the device, the fall protection function of the device will fail, leaving construction workers still at risk of falling. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A fall arrestor for power construction includes a first casing 1, a second casing 2 disposed on the outer side of the first casing 1, a fixing rod 3 fixedly connected to the inner wall of the first casing 1, and the inner wall of the second casing 2 rotatably connected to the outer surface of the fixing rod 3. Fastening bolts 11 are provided both inside the first casing 1 and inside the second casing 2. The outer surfaces of the fastening bolts 11 contact the inner walls of the first casing 1 and the second casing 2 respectively. The fastening bolts 11 can quickly insert and limit the movement of the two casings, and, in conjunction with other locking structures, ensure the stability of the overall structure during operation, preventing accidental loosening.

[0024] A connecting block 4 is fixedly connected to the inner wall of the first housing 1, and a first arc-shaped clamping block 5 is fixedly connected to the inner wall of the connecting block 4. A fastening nut 12 is threadedly connected to the outer surface of the fastening bolt 11. The end of the fastening nut 12 near the first housing 1 contacts the outer surface of the first housing 1. The fastening nut 12, through its threaded engagement with the fastening bolt 11, can further enhance the tightness of the connection between the first housing 1 and the second housing 2, prevent the connection from loosening due to vibration during long-term use, and improve the reliability of the device clamping.

[0025] The inner wall of the second housing 2 is fixedly connected to a support rod 6. A knocking rod 7 is provided inside the second housing 2. The inner wall of the knocking rod 7 is rotatably connected to the outer surface of the support rod 6. A washer 13 is sleeved on the outer surface of the fastening bolt 11. The side of the washer 13 closest to the second housing 2 contacts the outer surface of the second housing 2. When the fastening nut 12 is tightened, the washer 13 can increase the contact area with the outer surface of the second housing 2, disperse the tightening pressure, and prevent the surface of the second housing 2 from deforming or being damaged due to excessive force, thus extending the service life of the device.

[0026] A second arc-shaped clamping block 8 is provided on the outer side of the first arc-shaped clamping block 5. A support frame 9 is fixedly connected to the outer surface of the second arc-shaped clamping block 8. The outer surface of the support frame 9 is rotatably connected to the inner wall of the knocking rod 7. A first anti-slip sleeve 14 is fixedly connected to the inner wall of the first arc-shaped clamping block 5. Several identical first anti-slip grooves 15 are opened on the inner wall of the first anti-slip sleeve 14. The first anti-slip sleeve 14 and the several first anti-slip grooves 15 opened on the inner wall can increase the friction with the safety cable, prevent the device from sliding along the cable in the clamping state, and improve the safety of falling.

[0027] A hanging ring 10 is fixedly connected to the end of the striking rod 7 away from the support frame 9. A second anti-slip sleeve 16 is fixedly connected to the inner wall of the second arc-shaped clamping block 8. Several identical second anti-slip grooves 17 are opened on the inner wall of the second anti-slip sleeve 16. The second anti-slip sleeve 16 and the several second anti-slip grooves 17 opened on the inner wall cooperate with the first anti-slip sleeve 14 and the first anti-slip groove 15 to further enhance the clamping friction of the safety cable. The double anti-slip structure makes the clamping more stable and reduces the risk of falling.

[0028] The working principle of this utility model is as follows: When in use, first rotate the first shell 1 and the second shell 2 along the fixing rod 3 to open them, place the safety cable between the first arc-shaped clamp 5 and the second arc-shaped clamp 8, then rotate the second shell 2 to close it, pass the fastening bolt 11 through the two and tighten the fastening nut 12, and complete the initial fixation with the help of the washer 13. At this time, the construction personnel can connect the safety equipment to the hanging ring 10.

[0029] When the construction workers need to adjust the position of the device by moving upwards, the safety equipment will lift the knocking rod 7 upwards through the hanging ring 10. The knocking rod 7 rotates around the support rod 6 as the fulcrum, and drives the second arc-shaped clamping block 8 to move slightly outwards through the support frame 9, reducing the clamping force between it and the first arc-shaped clamping block 5. At this time, the device can move smoothly upwards along the safety cable without loosening the fastening bolts 11 and fastening nuts 12, and the fall protection function remains effective at all times.

[0030] In the event of an accidental fall, the device will slide downwards due to gravity. The safety equipment will then press down on the lever 7 via the hanging ring 10. Consequently, the second arc-shaped clamp 8 will press against the first arc-shaped clamp 5, locking the safety cable. The safety cable will generate reverse friction with the first anti-slip sleeve 14 and the second anti-slip sleeve 16, causing the second arc-shaped clamp 8 to move closer to the first arc-shaped clamp 5 under the action of friction. With the help of the meshing action of the first anti-slip groove 15 and the second anti-slip groove 17, the cable will be quickly locked and fixed, preventing the device from falling further and providing reliable safety protection for construction personnel. The design of the entire fall arrest device for power construction effectively solves the problem that the lack of a convenient locking structure that allows the device to move upwards along the safety cable has led to construction personnel having to loosen the device multiple times each time they need to move upwards. After the device is loosened, its fall arrest function will fail, leaving construction personnel still at risk of falling.
