Description

Technical Field

[0001] The utility model relates to an anchor rod protective cover. Background Art

[0002] Anchor rods are important equipment used for support installation. They are inserted into the inner wall of the tunnel to achieve support hoisting.

[0003] In actual operations, due to the force of the support, the anchor rod will be subjected to lateral force, which will eventually cause the anchor rod to deflect. In order to reduce this situation, we have designed an anchor rod protective cover that can be limited at the end of the anchor rod to limit the deflection of the anchor rod. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an anchor rod protective cover which can be limited at the end of the anchor rod and restrict the deviation of the anchor rod.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] An anchor rod protective cover comprises a protective sleeve, wherein the upper end of the protective sleeve is provided with a socket for inserting the anchor rod, the outer wall of the protective sleeve is provided with an ear plate, a cable is fitted through the ear plate, and the end of the cable away from the ear plate is equipped with a hook.

[0007] In the above technical solution, the protective sleeve is made of steel and is formed by turning, and the ear plate and the protective sleeve are connected by welding.

[0008] Preferably, a buffer device is installed in the protective sleeve.

[0009] Preferably, an adjusting bolt for adjusting the resistance of the buffer device is screwed into the bottom of the protective sleeve.

[0010] Preferably, the buffer device includes an upper and a lower slider, a spring is welded between the upper and lower sliders, and the adjusting bolt is screwed into the protective sleeve to support the lower slider.

[0011] Preferably, a socket is provided at the bottom of the lower sliding block, the inner diameter of the socket is larger than the diameter of the adjusting bolt, and the portion of the adjusting bolt inserted into the socket is the polished rod portion.

[0012] The beneficial effects of the utility model are:

[0013] Advantage 1: This device has a reasonable structure, is easy to install, has a quick disassembly design, and can be reused. It is easy to inspect and maintain, saves manpower and improves efficiency.

[0014] Advantage 2: The buffer device is easy to replace, ensuring long-term stability of the product. The double buffer design improves protection performance, reduces anchor damage, and reduces maintenance frequency.

[0015] Advantage three: The protective casing is equipped with a buffer device inside, which can disperse and absorb pressure when the anchor rod is impacted, provide additional buffer protection, reduce the risk of tilting and deviation, and significantly extend the service life of the anchor rod.

[0016] Advantage four: the cables on the protective casing can be adjusted for suitable installation, making it easy to hang and adapt to standard or complex areas, ensuring the stability and safety of the anchor rod. BRIEF DESCRIPTION OF THE DRAWINGS
