Description

Technical Field

[0001] This utility model relates to the field of mine safety management technology, and in particular to a high-strength edge rock-blocking device for mine safety management. Background Technology

[0002] Rockfalls around mines can pose a significant threat to passing vehicles and pedestrians, and can also damage roadbeds or bridges. To prevent the risk of falling rocks and ensure the safety of personnel and the surrounding environment, rockfall barriers are usually installed to effectively block rocks that may roll off the edge of the mine.

[0003] In existing technologies, rockfall protection is usually achieved using protective nets. During installation, support ropes and pre-embedded anchors are first installed to form a continuous support frame. The protective net is then laid out and the net is wrapped with stitching ropes to complete the installation and rockfall protection. However, both the support ropes and the protective net must be installed close to the slope surface, which can lead to poor deformation of the net during protection. When rocks fall, the net is easily damaged, thus affecting the protection effect. Utility Model Content

[0004] Therefore, it is necessary to address the problem that both the support rope and the protective net need to be installed close to the slope surface, which can easily lead to poor deformation of the protective net during the protection process. When there is a rockfall, the protective net is easily damaged, thus affecting the protection effect. To address this issue, a high-strength edge rock-blocking device for mine safety management is provided.

[0005] Includes: a protective net, support ropes, stitching ropes, and anchor bolts, wherein the sides of the protective net are fixedly connected to the support ropes via stitching ropes; A connecting mechanism includes a cylinder and two mounting blocks. Two steel wire ropes are fixedly connected to the surface of the cylinder. The ends of the two steel wire ropes away from the cylinder are respectively fixedly connected to the surfaces of the two mounting blocks. U-shaped blocks are fixedly connected to the opposite ends of the two mounting blocks. Round rods are rotatably connected to both sides of the inner wall of the U-shaped blocks. Card plates are fixedly connected to the surfaces of the two round rods. A coil spring is fixedly connected to the surface of one end of the round rod, and the other end of the coil spring is fixedly connected to the inner wall of the U-shaped block.

[0006] In one embodiment, the connecting mechanism further includes a connecting plate for mounting the anchor bolt. A connecting rod is fixedly connected to the other end of one of the mounting blocks, and the connecting rod is fixedly installed to the connecting plate using bolts and nuts. A ring for mounting a support rope is fixedly connected to the other end of the other mounting block. This ensures that the connecting mechanism is connected to the anchor bolt and the support rope.

[0007] In one embodiment, the overall shape of the clamping plate is "V" shaped, and the included angle at the bend of the clamping plate is greater than 90 degrees. This ensures the effective engagement of the clamping rod cylindrical mounting hole.

[0008] In one embodiment, a connecting spring is fixedly connected between the opposite sides of the two clamping plates. Both the coil spring and the connecting spring are alloy steel components. This ensures the clamping plates have the strength to move when they are clamped to the cylinder.

[0009] In one embodiment, a ribbon, made of plastic, is fixedly attached to the surface of the U-shaped block. This facilitates observation of whether the card plate has detached from the cylinder.

[0010] In one embodiment, a limiting block is fixedly connected to the surface of the connecting rod, and the overall shape of the limiting block is "U". This facilitates better alignment of the bolt mounting holes of the connecting rod with the bolt mounting holes of the connecting plate.

[0011] In one embodiment, the opposite ends of the two cylindrical rods both extend through a U-shaped block and are fixedly connected to a knob, with an operating hole at the end of the knob. This facilitates the placement of the two clamping plates into the cylinder by the operator.

[0012] In one embodiment, the connecting plate is U-shaped, which facilitates better installation with the connecting ring of the anchor rod.

[0013] Beneficial effects 1. When performing rockfall protection in a mine, the wire rope in the connecting mechanism is folded to ensure the operational effectiveness of the connecting mechanism. During the protection process, when the impact of falling rocks causes the protective net and support rope to bear a large force, the clamp plate detaches from the cylinder and unfolds the wire rope, which helps to buffer the impact force. At the same time, it allows the support rope and protective net to stretch to a certain extent, providing additional deformation space for the protective net and support rope, reducing the risk of damage to the protective net due to excessive instantaneous force, and improving the protection effect. 2. The addition of ribbons to the above-mentioned connecting mechanism allows staff to better observe whether the U-shaped block has detached from the cylinder, thereby determining whether the protective net and support rope can withstand the large impact of falling rocks, facilitating timely maintenance.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The following is combined Figures 1-5 This invention describes a high-strength edge rock-blocking device for mine safety management.

[0019] In one embodiment, a high-strength edge rock-blocking device for mine safety management includes: a protective net 100, a support rope 200, a stitching rope 300, and an anchor bolt 400. The side of the protective net 100 is fixedly connected to the support rope 200 through the stitching rope 300. The connecting mechanism 500 includes a cylinder 510 and two mounting blocks 520. Two steel wire ropes 530 are fixedly connected to the surface of the cylinder 510. The ends of the two steel wire ropes 530 away from the cylinder 510 are fixedly connected to the surfaces of the two mounting blocks 520 respectively. U-shaped blocks 540 are fixedly connected to the opposite ends of the two mounting blocks 520. Round rods 541 are rotatably connected to both sides of the inner wall of the U-shaped blocks 540. The surfaces of the two round rods 541 are fixedly connected to the plates 550. A coil spring 542 is fixedly connected to the surface of one end of the round rod 541. The other end of the coil spring 542 is fixedly connected to the inner wall of the U-shaped block 540.

[0020] In this embodiment, the number of protective net 100, support rope 200, sewing rope 300, anchor rod 400 and connecting mechanism 500 is selected according to actual usage requirements. Protective net 100, support rope 200 and sewing rope 300 are all steel wire components.

[0021] When installing the anchor bolt 400, the anchor bolt 400 hole position is determined and a hole is drilled at the hole position. After drilling, grout is injected and the anchor bolt 400 is inserted to provide a stable anchoring point. This is a known existing technology.

[0022] The sewing rope 300 connects the side of the protective net 100 to the support rope 200 by wrapping.

[0023] Both ends of the cylinder 510 are provided with rectangular holes. When the U-shaped block 540 is inserted into the cylinder 510 through the rectangular holes, the surface of the U-shaped block 540 fits against the inner wall of the rectangular holes. In the initial state, the clamping plate 550 in the connecting mechanism 500 is inside the cylinder 510, and the two steel wire ropes 530 are folded.

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, the connecting mechanism 500 also includes a connecting plate 560 that is installed with the anchor bolt 400. One of the mounting blocks 520 has a connecting rod 570 fixedly connected to its other end. The connecting rod 570 and the connecting plate 560 are fixedly installed together by bolts and nuts. The other end of the other mounting block 520 has a ring 580 fixedly connected to it for installing the support rope 200. The overall shape of the connecting plate 560 is U-shaped.

[0025] In this embodiment, the support rope 200 and the ring 580 are fixed by rope clips during installation. Both the connecting plate 560 and the connecting rod 570 have mounting holes for bolts. After connecting the connecting plate 560 and the anchor rod 400, the connecting rod 570 is inserted into the inner side of the connecting plate 560, and the mounting holes of the connecting plate 560 and the connecting rod 570 are aligned. The inner wall of the connecting plate 560 is in contact with the surface of the connecting rod 570. The bolts are passed through the mounting holes of the connecting plate 560 and the connecting rod 570, and the nuts and bolts are tightened to complete the installation of the connecting rod 570 and the connecting plate 560.

[0026] like Figure 5 As shown, the overall shape of the card plate 550 is "V" shaped, and the included angle at the bend of the card plate 550 is greater than 90 degrees. A connecting spring 543 is fixedly connected between the opposite sides of the two card plates 550. Both the coil spring 542 and the connecting spring 543 are alloy steel components.

[0027] In this embodiment, when the U-shaped block 540 is inserted into the cylinder 510 and the clamping plate 550 is placed inside the cylinder 510, the two coil springs 542 and the connecting spring 543 are in a released state. At this time, the two clamping plates 550 form an angle with the direction of the U-shaped block 540, and the connecting spring 543 can deform.

[0028] like Figure 5 As shown, a ribbon 590 is fixedly connected to the surface of the U-shaped block 540, and the ribbon 590 is a plastic component.

[0029] In this embodiment, the ribbon 590 can be a bright color. When the U-shaped block 540 and the cylinder 510 are installed, the ribbon 590 is placed inside the cylinder 510. When the U-shaped block 540 is separated from the cylinder 510, the ribbon 590 floats out. At this time, the ribbon 590 can be used to observe whether the U-shaped block 540 and the cylinder 510 are separated, thereby determining whether the protective net 100 and the support rope 200 can withstand a large impact force from falling rocks.

[0030] like Figure 5 As shown, a limiting block 571 is fixedly connected to the surface of the connecting rod 570, and the overall shape of the limiting block 571 is "U".

[0031] In this embodiment, when the connecting rod 570 is inserted into the inner side of the connecting plate 560, one end of the connecting plate 560 enters the limiting block 571, the surface of one end of the connecting plate 560 is in contact with the inner wall of the limiting block 571, and the mounting hole of the connecting plate 560 is aligned with the mounting hole of the connecting rod 570.

[0032] like Figure 5 As shown, the opposite ends of the two round rods 541 both pass through the U-shaped block 540 and are fixedly connected to a knob, and the end of the knob is provided with an operating hole.

[0033] In this embodiment, when installing the U-shaped block 540 in the connecting mechanism 500 with the cylinder 510, the two knobs are rotated using a tool and an operating hole, causing the two round rods 541 to drive the two clamping plates 550 to rotate. The coil spring 542 and the connecting spring 543 contract, and the connecting spring 543 deforms, allowing the two clamping plates 550 to enter the cylinder 510 through the rectangular holes at the ends of the cylinder 510. After the clamping plates 550 enter the cylinder 510, the force on the knobs is released, the coil spring 542 and the connecting spring 543 are released, and the clamping plates 550 are engaged with the cylinder 510.

[0034] Working principle: When installing this device for mine protection, multiple anchor bolts 400 are fixed to the slope as required. After the anchor bolts 400 are fixed, a suitable number of connecting mechanisms 500 are selected and installed with the anchor bolts 400. During installation, the connecting plate 560 is first connected to the mounting ring of the anchor bolt 400, and the connecting rod 570 is fixed to the connecting plate 560 using bolts and nuts. After the installation is completed, the two ends of the support rope 200 are installed to the rings 580 in the two connecting mechanisms 500 respectively through rope clips, and the support rope 200 is adjusted to a suitable tension. Then, the protective net 100 is installed and the side of the protective net 100 is fixed to the support rope 200 through the sewing rope 300. After the installation is completed, the mine can be protected.

[0035] During the protection process, when falling rocks impact the protective net 100 and the support rope 200, the force they bear increases. At this time, the support rope 200 applies a pulling force to the mounting block 520 and the cylinder 510. During this process, the cylinder 510 squeezes the clamping plate 550. When the pulling force applied by the support rope 200 to the mounting block 520 and the cylinder 510 is large, the two clamping plates 550 will be squeezed and rotated by the cylinder 510. The coil spring 542 and the connecting spring 543 are compressed, and the clamping plate 550 and the U-shaped block 540 are disengaged from the cylinder 510. At this time, the wire rope 530 unfolds, allowing the support rope 200 and the protective net 100 to stretch to a certain extent, providing additional deformation space for the protective net 100 and the support rope 200.

[0036] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
