Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, and in particular to a slope operation safety protection device. Background Technology

[0002] Slope protection in engineering can be divided into two categories: slope surface protection and retaining structure protection. Common measures for slope surface protection include mortar or rammed earth finishing, shotcreting, sprayed concrete, masonry retaining walls, anchored shotcrete slope protection, and anchored shotcrete mesh slope protection. These measures are mainly used to protect the slope surface from weathering, erosion, and minor rockfalls.

[0003] Slope work presents a significant risk of falls from heights due to the complex terrain. Current safety measures are often inadequate and fail to effectively protect workers. Therefore, a specialized safety device for slope work is needed to improve operational safety. Utility Model Content

[0004] This utility model discloses a safety protection device for slope operations. To achieve the above objectives, this utility model adopts the following technical solution:

[0005] A slope protection device includes a ground anchor, two limiting rings are symmetrically welded on both sides of the ground anchor, a ground nail is inserted and installed inside the limiting ring, a seamless upright is inserted and installed inside the limiting ring, a longitudinal column is inserted and installed inside the seamless upright, and a limiting component is fixedly connected to the top of the longitudinal column.

[0006] A steel wire rope is inserted through the upper end of the limiting component, and both ends of the steel wire rope are fixedly connected to the ground by turnbuckles. A fall arrestor is fitted on the surface of the steel wire rope, and the other end of the fall arrestor is used to connect to a five-point safety belt.

[0007] In a preferred embodiment, a positioning sleeve is fixedly connected to the top of the seamless upright. The surface of the positioning sleeve has positioning bolt holes, and an adjusting bolt is threaded onto the inner wall of the positioning bolt holes. The surface of the longitudinal column has several positioning screw holes, the positions of which correspond to the adjusting bolts, and the size of the positioning screw holes matches the size of the adjusting bolts.

[0008] In a preferred embodiment, the surface of the ground anchor is provided with a limiting screw hole, and the inner wall of the limiting screw hole is threaded with a clamping bolt, which is used to clamp and limit the seamless upright.

[0009] In a preferred embodiment, the limiting component includes a U-shaped limiting plate fixedly connected to the upper end of the longitudinal column. The top end of the U-shaped limiting plate is rotatably connected to an anti-detachment baffle via a rotating shaft. A torsion spring is sleeved on the surface of the rotating shaft. The other end of the torsion spring is fixedly connected to the surface of the rotating shaft and the other end of the torsion spring is fixedly connected to the surface of the anti-detachment baffle.

[0010] In a preferred embodiment, an extension block is fixedly connected to the inner surface of the U-shaped limiting plate, and one end of the anti-detachment baffle overlaps with the lower surface of the extension block. The extension block is used to limit the anti-detachment baffle.

[0011] In a preferred embodiment, the limiting component further includes a positioning ring, which is fixedly connected to the top of the longitudinal column and is used to connect the hook of the turnbuckle.

[0012] As can be seen from the above, the slope operation safety protection device provided by this utility model has the following technical effects.

[0013] Firstly, the protective device has strong comprehensive protection performance: the various components work together to ensure the safety of workers from multiple aspects, preventing falls and providing descent protection in the event of a fall. By setting limit components, it is convenient to switch the steel cable with anti-fall descent device between seamless uprights in different positions, and it can also prevent the steel cable from falling off the U-shaped limit plate, increasing the safety of use.

[0014] Secondly, by setting two turnbuckles at both ends of the wire rope, the tension of the wire rope can be quickly adjusted, avoiding the risk of the wire rope falling off the U-shaped limit plate due to being too loose. In addition, if the wire rope is too loose, it will be inconvenient for the operator to switch between seamless uprights.

[0015] Thirdly, the protective device is highly reliable: all components are made of high-strength, high-quality materials, ensuring the reliability and stability of the protective device during slope operations. 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 and Figure 2 A slope operation safety protection device includes a ground anchor 1. Two limiting and fixing rings 2 are symmetrically welded on both sides of the ground anchor 1. Ground anchors 3 are inserted and installed inside the limiting and fixing rings 2. Seamless uprights 4 are inserted and installed inside the limiting and fixing rings 2. Longitudinal columns 5 are inserted and installed inside the seamless uprights 4. A limiting component 6 is fixedly connected to the top of the longitudinal column 5.

[0024] It should be noted that the ground anchor 1 is a round tube with a diameter of 50mm*400mm, and will be welded to 4 pre-inserted ground anchors 1 with a diameter of 25mm*50mm. The weld length is not less than 60mm. The ground nail 3 is a round tube with a diameter of 100mm*300mm, and the seamless pole 4 is a round tube with a diameter of 350mm*2000mm.

[0025] Made of high-strength alloy steel, the device is designed in a conical shape with a sharp tip for easy insertion into the slope. The main body of the ground anchor 1 has multiple limiting screw holes for connecting the seamless pole 4, ensuring its firm fixation on the slope and enabling it to withstand greater tensile and impact forces. The seamless pole 4 is made of rust-resistant seamless steel pipe, possessing high strength and stability. The seamless pole 4 can be inserted into the fixing hole of the ground anchor 1 and tightened by the tightening bolt 12. Its height can be adjusted according to the specific needs of the slope operation, providing a vertical support structure for the entire protective device.

[0026] It should be noted that the surface of the ground fixing device 1 is provided with a limiting screw hole, and the inner wall of the limiting screw hole is threaded with a clamping bolt 12. The clamping bolt 12 is used to clamp and limit the seamless upright 4.

[0027] Furthermore, the limiting component 6 includes a U-shaped limiting plate 601 and a positioning ring 605 fixedly connected to the longitudinal column 5. The top end of the U-shaped limiting plate 601 is rotatably connected to an anti-detachment baffle 603 via a rotating shaft 602. A torsion spring is sleeved on the surface of the rotating shaft 602. The other end of the torsion spring is fixedly connected to the surface of the rotating shaft 602 and the other end of the torsion spring is fixedly connected to the surface of the anti-detachment baffle 603.

[0028] Specifically, the positioning ring 605 is fixedly connected to the top of the longitudinal column 5, and the positioning ring 605 is set on the top of the two outermost longitudinal columns 5. The two ends of the wire rope 8 are connected and fixed to the ground anchors, and the wire rope 8 is used to connect the tops of all the seamless poles 4 in series to improve the overall stability of the protective device.

[0029] It should be noted that steel wire ropes 8 are inserted through the U-shaped limit plate 601 and the positioning ring 605, and the two ends of the steel wire ropes 8 are fixedly connected to the ground by turnbuckles 7. The surface of the steel wire ropes 8 is also fitted with a five-point safety belt with a fall arrestor 9. The end of the fall arrestor 9 away from the five-point safety belt is fitted with a steel wire on the surface of the steel wire ropes 8, so as to facilitate the movement of workers to the construction position.

[0030] The fall arrestor 9 is a core component that can automatically activate when a worker accidentally falls. Through its internal braking device and descent mechanism, it allows the worker to descend at a safe speed, avoiding injury from the fall.

[0031] Five-point harness: Ergonomically designed with five straps for the shoulders, waist, and hips, it securely fastens the worker's body to the protective device. The harness is made of soft and comfortable material, yet it is strong and can withstand considerable tensile force.

[0032] Use stainless steel turnbuckles with a specification of 7.2mm opening, 10.8mm inner diameter, 91mm frame, and a telescopic range of 145-217mm.

[0033] Through the above technical solution, the turnbuckle 7 is used to adjust the tightness of the wire rope 8. The two ends of the turnbuckle 7 are connected to the wire rope 8 respectively. By rotating the adjusting nut in the middle of the turnbuckle 7, the wire rope 8 can be easily tightened or loosened.

[0034] It is worth noting that the overall structure of the protective device is easy to install and adjust. The design of the ground fixing device 1, the seamless upright 4, and the turnbuckle 7 allows the device to be quickly installed and adjusted according to different slope conditions, adapting to different operating scenarios.

The surface of the positioning sleeve 10 is provided with positioning bolt holes, and an adjusting bolt 11 is threadedly connected to the inner wall of the positioning bolt holes. A number of positioning screw holes are provided on the surface of the longitudinal column 5. The positions of the positioning screw holes correspond to the adjusting bolts 11, and the size of the positioning screw holes matches the adjusting bolts 11.

[0036] It is worth noting that the protective device is highly reliable: all components are made of high-strength, high-quality materials, ensuring the reliability and stability of the protective device during slope operations.

[0037] It should be noted that an extension block 604 is fixedly connected to the inner surface of the U-shaped limiting plate 601, and one end of the anti-detachment baffle 603 overlaps with the lower surface of the extension block 604. The extension block 604 is used to limit the anti-detachment baffle 603.

[0038] This protective device boasts strong comprehensive protection: its various components work together to ensure the safety of workers from multiple aspects, preventing falls and providing descent mitigation protection in the event of a fall.

[0039] Working principle: At the slope operation site, first insert the ground anchor 1 into a suitable position on the slope ground and fix the ground anchor 1 with the ground anchor nail 3. Then, insert the seamless pole 4 into the fixing hole of the ground anchor 1 and tighten it. Next, pass the steel wire rope 8 with turnbuckles 7 at both ends through the positioning ring 605 and the U-shaped limiting plate 601 and fix it to the ground. Put the steel wire with the fall arrestor 9 on the steel wire rope 8. Then, the workers put on the five-point safety belt and connect the safety belt to the fall arrestor 9. During the preparation process, the steel wire rope 8 can be easily tightened or loosened by rotating the adjusting nut in the middle of the turnbuckle 7.
