Description

Technical Field

[0001] This utility model relates to the field of quick assembly and disassembly technology of electrical cabinets, and in particular to a high-strength alloy anchor rod. Background Technology

[0002] Traditional anchor bolts are mostly made of ordinary steel. When dealing with increasingly complex and demanding engineering environments, the problem of insufficient strength becomes more and more obvious. With the increase in the depth of underground engineering and the increase in the bearing pressure of large building structures, the tensile strength and shear strength of ordinary anchor bolts can no longer meet the requirements. For example, in deep mining, when the mining depth reaches a certain level, the ground stress increases significantly. The tensile strength of traditional anchor bolts may only be 500-800MPa, while in actual engineering environments, anchor bolts need to withstand tensile forces of more than 1000MPa. This can easily lead to anchor bolt yielding or breakage, causing the support structure to lose its function.

[0003] Traditional anchor bolts have poor corrosion resistance in harsh natural or specific industrial environments, which is a major drawback. They also cannot accurately locate their depth when inserted into the ground, and they cannot automatically fix themselves after being inserted, which may cause the anchor bolts to shift during subsequent use.

[0004] In view of this, we have studied and improved the existing problems to provide a high-strength alloy anchor rod with a reasonable structural design, high stability, and comprehensive application. The aim of this technology is to solve the problems and improve its practical value. Utility Model Content

[0005] This invention pre-fixes the equipment before it is inserted into the ground, preventing the drill bit from deviating during drilling and ensuring precise positioning before drilling. Furthermore, it allows grout to be discharged through a slot after the anchor rod enters the ground, effectively addressing voids in special circumstances and achieving a high-strength alloy anchor rod.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength alloy anchor bolt, comprising an anchor bolt body, a pad provided on the outer side of the anchor bolt body, a nut movably connected to the upper end of the pad, a fixing hole provided on the side of the pad near the lower end, sliding grooves provided on both sides of the anchor bolt body, a fixing seat connected to the lower end of the pad, fixing rods provided around the pad, a protrusion fixedly connected to the inner side of the fixing seat, a drill bit fixedly connected to the lower end of the protrusion, and a slot provided on the outer side of the drill bit.

[0007] Preferably, the anchor body is hollow inside, and its outer side is threaded. The pad has a through hole at the center, and its inner side is threaded. The pad and the anchor body are threaded together.

[0008] Preferably, the nut is threaded to the anchor rod body and is located at the upper end of the pad. The grooves are opened on both sides of the anchor rod body, and there are two sets of them. The two sets of grooves do not completely penetrate the anchor rod body, and no threads are provided at their openings.

[0009] Preferably, the fixing seat has a through hole at its center, the inner diameter of which matches the outer diameter of the anchor rod body, and the fixing seat is movably connected to the outside of the anchor rod body.

[0010] Preferably, the fixing rod is fixedly connected to the through hole inside the fixing seat, and there are two sets of them. The fixing rod matches the inner diameter of the slide groove, and the fixing seat is fixed through the slide groove.

[0011] Preferably, the fixing rod is fixedly connected around the fixing seat, extends upward through the fixing seat, and the lower end of the fixing rod is a pointed head. The outer diameter of the part extending upward matches the inner diameter of the fixing hole and is at the same vertical angle as the fixing hole.

[0012] Preferably, the drill bit is fixedly connected to the lower end of the anchor rod body, and a slot is provided on one side of the drill bit, which is connected to the hollow part inside the anchor rod body.

[0013] This utility model has the following beneficial effects: the lower end of the fixing rod 7 is longer than the drill bit 9, so before going deep into the ground, the fixing seat 6 is first fixed by inserting four sets of fixing rods 7 into the ground surface to fix the equipment, thereby accurately positioning the position, and after fixing, it is also more stable, thus preventing displacement during long-term use. If rotation is required for drilling, the fixed rods 7 need to be removed, thus preventing the fixing seat 6 from being unable to rotate due to the fixing rods 7 when rotating synchronously. The fixing seat 6 pre-fixes the equipment before it is inserted into the ground, so that the drill bit 9 is prevented from deviating during drilling, and can also be accurately positioned before drilling.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-4 The present invention provides an embodiment of a high-strength alloy anchor bolt, comprising an anchor bolt body 1, a pad 2 provided on the outer side of the anchor bolt body 1, a nut 3 movably connected to the upper end of the pad 2, a fixing hole 4 opened on the side of the pad 2 near the lower end, sliding grooves 5 opened on both sides of the anchor bolt body 1, a fixing seat 6 connected to the lower end of the pad 2, fixing rods 7 provided around the perimeter, a protrusion 8 fixedly connected to the inner side of the fixing seat 6, a drill bit 9 fixedly connected to the lower end of the protrusion 8, and a slot 10 opened on the outer side of the drill bit 9.

[0022] In an optional embodiment: the anchor body 1 is hollow inside, and its outer side is threaded. The pad 2 has a through hole at the center, and its inner side is threaded. The pad 2 and the anchor body 1 are threaded together. The anchor body 1 is made of nickel-based alloy. Nickel-based alloy has excellent high temperature resistance, corrosion resistance, and high strength and toughness. It can still maintain good mechanical properties in high temperature environment, so that it is more stable in use. Its hollow interior allows for mud pouring during use.

[0023] In an optional embodiment: the nut 3 is threadedly connected to the anchor body 1 and is located at the upper end of the pad 2. The grooves 5 are opened on both sides of the anchor body 1, and there are two sets of them. The two sets of grooves 5 do not completely penetrate the anchor body 1, and no threads are provided at the opening. When the pad 2 is used, the whole can bear greater surrounding rock stress. At the same time, when the nut 3 is used, it will concentrate the stress of the surrounding rock onto the pad 2.

[0024] In an optional embodiment: a through hole is provided at the center of the fixing seat 6, the inner diameter of which matches the outer diameter of the anchor body 1, and the fixing seat 6 is movably connected to the outside of the anchor body 1. The fixing seat 6 will pre-fix the equipment before it is inserted into the ground, so as to prevent the drill bit 9 from deviating during drilling and to accurately position it before drilling.

[0025] In an optional embodiment: two sets of fixing rods 7 are fixedly connected to the through holes inside the fixing seat 6, and the fixing rods 7 match the inner diameter of the slide groove 5. The fixing seat 6 is fixed through the slide groove 5. When the anchor rod 1 enters the ground, the fixing seat 6 will stay at the upper end of the ground. As the anchor rod 1 continues to go deeper, the fixing seat 6 will rise continuously along the slide groove 5 through the protrusion 8. Thus, when the fixing seat 6 moves, the slide groove 5 provides a guiding function to prevent the fixing seat 6 from getting stuck. At the same time, it also allows the fixing rod 7 to be accurately connected to the upper fixing hole 4.

[0026] In an optional embodiment: the fixing rod 7 is fixedly connected around the fixing base 6, extending upward through the fixing base 6. The lower end of the fixing rod 7 is a pointed tip, and the outer diameter of the part extending upward matches the inner diameter of the fixing hole 4 and is at the same vertical angle as the fixing hole 4. When the equipment is inserted into the ground, because the lower end of the fixing rod 7 is longer than the drill bit 9, the fixing base 6 is first fixed to the ground surface by inserting four sets of fixing rods 7 before going deep into the ground, so as to accurately position the equipment and make it more stable after fixing, thereby preventing displacement during long-term use. If rotation is required for drilling during use, the fixed rod 7 needs to be removed to prevent the fixing base 6 from being unable to rotate due to the fixing rod 7 when rotating synchronously.

[0027] In an optional embodiment: the drill bit 9 is fixedly connected to the lower end of the anchor body 1, and a useful slot 10 is opened on one side of it. The slot 10 is connected to the hollow part inside the anchor body 1. When grouting is performed after the anchor body 1 enters the ground, it will be discharged through the slot 10, thereby providing an effective response to cavities in special circumstances.

[0028] Working principle and process: When inserting the equipment into the ground, because the lower end of the fixing rod 7 is longer than the drill bit 9, the fixing seat 6 is first fixed to the ground surface by inserting four sets of fixing rods 7 before going deep underground, thus accurately positioning the equipment and making it more stable after fixing, thereby preventing displacement during long-term use. If rotation is required for drilling, the fixed rods 7 need to be removed to prevent the fixing seat 6 from being unable to rotate due to the fixing rods 7 when rotating synchronously. When the anchor body 1 enters the ground, the fixing seat 6 will stay at the upper end of the ground. As the anchor body 1 continues to go deeper, the fixing seat 6 will rise continuously along the slide groove 5 through the protrusion 8. The slide groove 5 provides guidance for the movement of the fixing seat 6, thereby preventing the fixing seat 6 from getting stuck. At the same time, the fixing rod 7 can be accurately connected to the upper fixing hole 4. When grouting is carried out after the anchor body 1 enters the ground, it will be discharged through the empty groove 10, thus providing an effective solution for special situations of cavities.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
