Description

Technical Field

[0001] This utility model relates to a hook pile structure for electric scraper operations in mining areas. Background Technology

[0002] In mining operations, backfilling is the primary mining method in areas such as the 630 mining zone. Whether backfilling or scraping operations are performed, electric scraper hook piles must be installed near the backfill shaft to secure the scraper and guide its operation. Currently, the electric scraper hook piles used in the mining area have undergone two main generations of product development:

[0003] 1. Circular hook pile: Made of No. 40 threaded steel welded into a circular structure, this hook pile is heavy (over 3kg per pile) and bulky, making it inconvenient to carry; moreover, the welded structure has insufficient strength, and it is prone to deformation and breakage due to uneven stress during electric rake dragging, resulting in a high damage rate; at the same time, the circular hook pile is fixed to the surrounding rock by welding or deep burial, and installation and removal require heavy tools, which is laborious. The average monthly usage of a single mining area reaches 10-15 piles, resulting in a large consumption of steel.

[0004] 2. Wedge-shaped hook pile: As an improved version of the circular hook pile, although it has been slightly optimized in structure, it still has obvious defects: the way the wedge structure is combined with the surrounding rock means that it must be forcibly embedded in the surrounding rock during installation, and it is easy to get stuck due to the pressure of the surrounding rock when it is removed, making disassembly difficult; moreover, its material and structure have not solved the problem of "easy deformation when dragged by electric scraper", and the average monthly usage in a single mining area is still 12, with a single weight of 2.784kg, and the problems of steel consumption and labor intensity have not been fundamentally improved.

[0005] The aforementioned two types of hook piles not only lead to high steel costs in the mining area, but also increase the labor intensity of workers and reduce the overall labor productivity of the mining area due to the time-consuming and labor-intensive installation and dismantling, thus failing to meet the needs of efficient and low-cost mining operations. Utility Model Content

[0006] The main purpose of this utility model is to provide a hook pile structure for electric scraper operations in mining areas, aiming to solve the problem.

[0007] To achieve the above objectives, this utility model proposes a hook pile structure for electric scraper operations in mining areas, comprising a sleeve body, a conical plug, a steel wire rope, and a matching anchor rod. The sleeve body has an inner cavity, and the steel wire rope can be wound around the inner cavity after being twisted. The conical plug can be inserted into the inner cavity from the end of the sleeve body. The sleeve body and the matching anchor rod are both installed in the hole, and the outer wall surface of the sleeve body and the outer wall surface of the matching anchor rod are in contact with each other.

[0008] In one embodiment, the inner diameter of the sleeve body is 2-4 cm.

[0009] In one embodiment, the sleeve body has a length of 8-12cm, an outer diameter of 3-5cm, and a wall thickness of 0.5-1cm.

[0010] In one embodiment, the sleeve body is made of steel.

[0011] In one embodiment, the conical plug is conical in shape and is adapted to the taper of the inner cavity of the sleeve body.

[0012] In one embodiment, the taper of the tapered plug is 1:5–1:8.

[0013] In one embodiment, the conical plug is made of cemented carbide.

[0014] In one embodiment, the length of the matching anchor rod is 30-50cm.

[0015] In this invention, the hook pile structure for electric scraper operations in mining areas includes a sleeve body, a conical plug, a steel wire rope, and a matching anchor rod. The sleeve body has an inner cavity, and the steel wire rope, after being twisted, can be wound around the inner cavity. The conical plug can be inserted into the inner cavity from the end of the sleeve body. Both the sleeve body and the matching anchor rod are installed in holes, and the outer wall surface of the sleeve body and the outer wall surface of the matching anchor rod are in contact with each other. Therefore, in this invention, the combined use of the sleeve body and the matching anchor rod, along with the compression and fixation with the surrounding rock, can improve the resistance to deformation. Simultaneously, the compression and fixation method of the conical plug can prevent the steel wire rope from loosening, making it less prone to damage during electric scraper dragging, effectively increasing the average service life of the hook pile and reducing the frequency of replacement.

[0025] This utility model provides a hook pile structure for electric scraper operations in mining areas.

[0026] like Figure 1-2 As shown, the hook pile structure for electric scraper operation in mining areas provided by this utility model embodiment includes a sleeve body 2, a conical plug 1, a steel wire rope 5, and a matching anchor rod 4. The sleeve body 2 has an inner cavity, and the steel wire rope 5 can be wound in the inner cavity after being twisted. The conical plug 1 can be inserted into the inner cavity from the end of the sleeve body 2. The sleeve body 2 and the matching anchor rod 4 are both installed in the hole, and the outer wall surface of the sleeve body 2 and the outer wall surface of the matching anchor rod 4 are in contact with each other.

[0027] In this application, the surrounding rock surface is first cleaned at a predetermined location near the filling well in the mining area to ensure a flat installation surface. Then, the end of the electric scraper wire rope 5 is twisted open, and the twisted section of wire rope 5 is inserted into the inner cavity of the sleeve body 2. The conical plug 1 is then inserted from the open end of the sleeve body 2 until the conical plug 1 is tightly fitted with the wire rope 5 and the inner cavity of the sleeve body 2, thus fixing the wire rope 5. Finally, a hole 3 is drilled in the surrounding rock next to the side wall of the sleeve body 2, and the matching anchor rod 4 is driven into the drilled hole 3, so that the end of the anchor rod is pressed against the outer wall of the sleeve body 2, squeezing and fixing the sleeve body 2 to the surrounding rock. After use, only the matching anchor rod 4 needs to be pulled out to directly remove the sleeve body 2 and the conical plug 1, completing the disassembly.

[0028] The hook pile structure for electric scraper operations in mining areas provided in this application can improve the resistance to deformation. At the same time, the compression fixing method of the conical plug 1 can prevent the wire rope 5 from loosening, making it less prone to damage when the electric scraper is dragged, which can effectively improve the average service life of the hook pile and reduce the frequency of replacement.

[0029] The sleeve body 2 is made of wear-resistant low-carbon steel and has a hollow columnar structure. The inner diameter is designed to be 2-4cm according to the diameter of the commonly used electric rake wire rope 5, so as to ensure that the twisted wire rope 5 can be stably embedded. The length of the sleeve body 2 is controlled at 8-12cm, the outer diameter is 3-5cm, the wall thickness is 0.5-1cm, and the single weight is only 0.426kg, which not only ensures structural strength, but also greatly reduces weight, making it easy for operators to carry.

[0030] The conical plug 1 is made of hard alloy and has a conical shape. Its taper matches the taper of the inner cavity of the sleeve body 2, with a taper ratio of 1:5 to 1:8. Its function is to firmly fix the wire rope 5, which is inserted into the inner cavity of the sleeve and twisted, through the principle of "compression fixing", to prevent the wire rope 5 from loosening or falling off during electric rake operation.

[0031] The matching anchor bolt 4 is made of threaded steel with a diameter of 16-18mm, and its length is designed according to the thickness of the surrounding rock, usually 30-50cm. Its function is to firmly fix the sleeve body 2 to the surrounding rock of the mining area through "outer wall compression". After drilling the surrounding rock hole 3 next to the sleeve body 2, the anchor bolt is driven in, and the end of the anchor bolt is pressed against the outer wall of the sleeve, so that the sleeve body 2 and the surrounding rock form a stable fixed structure, preventing the sleeve from shifting when the electric scraper is dragged.

[0032] Compared with the prior art, this application has the following significant advantages:

[0033] 1. Save steel and reduce costs: The average monthly usage of traditional wedge hook piles in a single mining area is 12, with a single weight of 2.784 kg. The average monthly usage of this application in a single mining area is only 3.5, with a single weight of 0.426 kg.

[0034] Taking Hunan Xinlong Mining's No. 630 pithead (10 mining areas, 11 months of annual production) as an example, the amount of steel that can be saved each year is calculated as follows: 10 mining areas × 11 months × (12 mining areas / month × 2.784 kg / mining area - 3.5 mining areas / month × 0.426 kg / mining area) = 3510.9 kg, which significantly reduces the cost of steel procurement and replacement.

[0035] 2. Convenient installation and disassembly, reducing labor intensity: Traditional hook pile installation requires 2-3 people with heavy tools, and disassembly is prone to jamming and requires cutting; this application only requires 1 person to install and disassemble, without heavy tools, and the disassembly time is reduced from the traditional 30 minutes / piece to 5 minutes / piece, significantly reducing the labor intensity of operators and reducing the time consumed in operation.

[0036] 3. Robust structure and high durability: The sleeve body 2 is made of wear-resistant steel, which, together with the anchor rod and the surrounding rock, is squeezed and fixed, improving the deformation resistance; the compression and fixing method of the conical plug 1 prevents the wire rope 5 from loosening, and it is not easy to be damaged when the electric rake is dragged. The average service life of the hook pile is extended from the traditional 1 month to more than 3 months, reducing the frequency of replacement.

[0037] 4. Small size and easy to carry: This application weighs only 0.426kg and is 1 / 4 the size of a traditional hook pile. Operators can carry 10-15 at a time without the need for additional transportation, which improves the convenience of operation.

[0038] The following describes in detail the specific implementation method of this application, taking into account the actual application scenario of the No. 630 pithead of Hunan Xinlong Mining.

[0039] Sleeve body 2: Made of Q235 wear-resistant steel, 10cm in length, 4cm in outer diameter, 0.8cm in wall thickness, 3cm in inner cavity diameter, 0.426kg in weight, 50 pieces are processed per batch, which can meet the needs of 10 mining areas for 1 month.

[0040] Conical plug 1: Made of hard alloy, with a taper of 1:6, a length of 5cm, a maximum diameter of 3cm, and is adapted to the inner cavity of sleeve body 2.

[0041] Matching anchor rod 4: Made of 16-18mm diameter threaded steel, 50cm in length, with the end ground into a pointed shape for easy insertion into drill hole 3.

[0042] One worker carries the sleeve body 2, conical plug 1, matching anchor rod 4, and drilling tools 3 to the work site; after cleaning the surrounding rock surface, twist the end of the electric rake wire rope 5 (about 8cm in length) and insert it into the inner cavity of the sleeve body 2; insert the conical plug 1 until it fits tightly; use a handheld drilling machine 3 to drill a hole with a diameter of 38mm and a depth of 30-50cm 5cm away from the sleeve, drive the anchor rod in until the end is pressed against the outer wall of the sleeve, and complete the installation. The installation of a single hook pile takes about 8 minutes.

[0043] 2. Results of use: The hook piles of this application were used for ore scraping operations in this mining area. When the electric scraper was dragged, the sleeve body 2 did not shift or deform, and the wire rope 5 did not loosen. After one month of continuous operation, the hook piles remained intact and showed no signs of damage.

[0044] 3. Disassembly operation: After the operation is completed, use a wrench to pull out the anchor rod, and directly remove the sleeve body 2 and the conical plug 1. The disassembly of a single part takes about 3 minutes. The removed sleeve body 2 can be reused after cleaning, with a reuse rate of 80%.

[0045] After the implementation of this embodiment was tested at a mining site in the 630 pit, the traditional circular and wedge-shaped hook piles were completely phased out, and all the hook piles were replaced by the sleeve-type hook piles of this application. This resulted in a cumulative saving of more than 45,500 kg of steel, a 73.3% reduction in the labor time spent by workers installing the hooks, and a 10% increase in the efficiency of mining site scraping operations, achieving significant economic and social benefits.

[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
