Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering, in particular to an anchor rod for municipal engineering. Background Art

[0002] Anchor rods are steel bars or steel pipes used in underground projects. They play a role in strengthening and stabilizing soil and rock by combining with surrounding rocks to bear horizontal tension. Anchor rods were first widely used in tunnels and underground mining, and are now also used in engineering technology. At present, anchor rods have become one of the indispensable materials in various underground projects.

[0003] The existing anchor technology uses an ordinary rock drill to drill a hole, then inserts the anchor with the anchor head installed into the hole, injects an anchoring agent or concrete into the hole, and finally installs a grout plug, a pad, and a nut.

[0004] In the prior art, anchor rods have a fixed length, which means that there are limitations when the anchor rod length needs to be adjusted to adapt to different geological conditions or engineering requirements. This leads to mismatched anchor rod performance and cannot be optimized to the greatest extent. Therefore, an anchor rod for municipal engineering is proposed to solve the above problem. Utility Model Content

[0005] In order to remedy the above deficiencies, the utility model provides an anchor rod for municipal engineering, aiming to improve the problem in the prior art that after the anchor rod is installed, it is usually difficult or impossible to remove, which means that if the structure needs to be changed or repaired, the anchor rod may become a limiting factor, requiring additional engineering costs and complexity.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An anchor rod for municipal engineering, comprising a telescopic shell, a fixed shell fixedly connected to the right side of the telescopic shell, a pull rod slidably connected inside the fixed shell, a spring sleeved on the outer periphery of the pull rod, a telescopic rod slidably connected to the left side of the pull rod, the telescopic rod slidably connected to the inside of the telescopic shell, a push plate fixedly connected to the left side of the spring, the push plate fixedly connected to the outer periphery of the pull rod, the right side of the spring abuts against the right side inside the fixed shell, and a fixing component is arranged at the bottom of the telescopic shell;

[0023] 1. The pull rod can be stretched through the spring and the push plate. When the telescopic rod needs to be extended, pull out the pull rod, slide the telescopic rod to adjust to the required length, and then release the pull rod. Because a spring is provided on the outer periphery of the pull rod, the pull rod will be reinserted into the telescopic rod when the pull rod is released.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-Figure 3The utility model provides an embodiment: an anchor rod for municipal engineering, including a telescopic shell 1, which plays a protective role. The right side of the telescopic shell 1 is fixedly connected to a fixed shell 2, which is used for fixing and protection. A pull rod 3 is slidably connected inside the fixed shell 2, and the pull rod 3 can play a fixing role. A spring 4 is sleeved on the outer periphery of the pull rod 3, and the spring 4 can generate elastic force. A telescopic rod 11 is slidably connected to the left side of the pull rod 3, and the telescopic rod 11 is slidably connected to the inside of the telescopic shell 1. A push plate 5 is fixedly connected to the left side of the spring 4, and the push plate 5 is fixedly connected to the outer periphery of the pull rod 3. When the pull rod 3 is pulled, the push plate 5 will squeeze the spring 4 to generate elastic force. The right side of the spring 4 abuts against the right side inside the fixed shell 2, and a fixing component is arranged at the bottom of the telescopic shell 1.

[0034] Reference Figure 2-Figure 5 The fixed component includes a connecting piece 6, which is fixedly connected to the outer periphery of the telescopic shell 1. The bottom end of the connecting piece 6 is fixedly connected to a connecting block 7, and the connecting block 7 is slidably connected to a slider 8. The slider 8 can slide inside the connecting block 7. The side of the slider 8 away from the telescopic shell 1 is fixedly connected to a conical needle 9, and the conical needle 9 can move with the slider 8. The conical needle 9 can penetrate into the soil for reinforcement. The bottom end of the slider 8 close to the telescopic shell 1 is fixedly connected to a slide rod 13, and the slide rod 13 will drive the slider 8 to move when it moves. The outer periphery of the slide rod 13 is slidably connected to a base 10, and the base 10 is rotatably connected to the outer periphery of the telescopic shell 1. The right side of the base 10 is rotatably connected to an electric push rod 17, and the electric push rod 17 can provide power to drive the base 10 to rotate back and forth.

[0035] Reference Figure 3-Figure 5 A pull block 15 is fixedly connected to the right side of the pull rod 3, and the pull block 15 can facilitate the pull rod 3 to be pulled out better. A plurality of evenly distributed arc grooves 14 are opened inside the base 10, and the sliding rod 13 slides inside the sliding arc groove 14. The curvature of the arc groove can enable the slider 8 to drive the conical needle 9 to extend, so that the conical needle has enough length to penetrate into the surrounding soil for fixation. A plurality of evenly distributed fixing holes are opened on the right side of the telescopic rod 11, and the pull rod 3 slides in the plurality of telescopic rod 11 fixing holes to fix the telescopic rod. A baffle 12 is fixedly connected to the top of the telescopic rod 11, and the baffle 12 can limit the telescopic length of the telescopic rod 11 to prevent the telescopic rod 11 from sliding out of the telescopic housing 1. The baffle 12 is slidably connected inside the telescopic housing 1, and a support plate 16 is fixedly connected to the bottom end of the electric push rod 17, and the support plate 16 can support the electric push rod 17. A hole groove is opened in the middle of the support plate 16, and the telescopic rod 11 slides in the hole groove of the support plate 16.

[0036] Working principle: When the telescopic rod 11 needs to be extended or retracted, the pull rod 3 can be pulled out. At this time, because there are springs 4 and push plates 5 on the outer periphery of the pull rod 3, and the push plates 5 are fixedly connected to the pull rod 3, when the pull rod 3 is pulled, the push plates 5 will squeeze the springs 4 to generate elastic force, and the telescopic rod 11 will be adjusted to a suitable length. After the telescopic rod 11 is adjusted, when the pull rod 3 is released, the pull rod 3 will bounce back into the fixing hole of the telescopic rod 11 due to the elasticity of the spring 4, and the anchor rod will be extended or retracted. When the anchor rod is extended or retracted to a suitable length, it can be placed in the drilled hole, and then the electric push rod 17 is started. When the electric push rod 17 is started, it will push the base 10 to rotate, and when the base 10 rotates, it will drive the slide bar 13 to move. When the slide bar 13 moves, it will drive the slider 8 to slide in the connecting block 7. When the slider 8 slides, it will drive the conical needle 9 to move. When the conical needle 9 penetrates into the soil, the anchor rod is fixed so that it will not move.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
