[0002] With the acceleration of urbanization, there are more and more slope protection projects in cities. Traditional slope protection projects often use concrete structures, but this method has some problems, such as high material costs, long construction periods, and great damage to the environment. Therefore, it is urgent to develop a more environmentally friendly, economical, and efficient slope protection construction method.

[0003] In the prior art, when completing the excavation of the holes in the protection slope and placing the anchor rods in the holes, the anchor rods are usually placed directly by manual labor. After the anchor rods are completely placed in the holes, the anchor rods are only positioned at the center axis of the holes by adjusting their positions at the hole mouth. However, the anchor rods at the bottom of the holes cannot be adjusted to be centered, causing the anchor rods to be tilted relative to the holes, resulting in reduced strength after the concrete is poured.

[0004] In view of the above problems, the present invention provides an anchor rod installation and positioning structure to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0033] Reference Figures 1 to 5 , the present invention provides a technical solution: an anchor rod installation and positioning structure, comprising: a fixing block 1, a clamping hoop 2, and a centering adjustment mechanism 3;

[0034] The clamping hoop 2 is fixed on one end face of the fixing block 1 and is used to pre-clamp the anchor rod, and a plurality of elastic clamping pads 5 are fixedly arranged around the circumference of the clamping hoop 2, and the plurality of elastic clamping pads 5 are used to preliminarily center and limit the anchor rod;

[0035] The centering adjustment mechanism 3 is arranged on the other end surface of the fixing block 1, and is used to keep the anchor rod coaxial with the hole when installing the anchor rod.

[0036] As a preferred embodiment, four sliding grooves 4 are diagonally provided on one side of the fixing block 1 close to the centering adjustment mechanism 3 , and a first connecting hole is coaxially provided relative to the clamping hoop 2 .

[0037] When installing the anchor rod, first install one end of the anchor rod in the clamping hoop 2 through the elastic clamping pad 5, and perform preliminary centering limit clamping. After completing the above operations, slowly put this end into the hole. When the anchor rod is completely placed in the hole, apply pressure to the anchor rod, so that the centering adjustment mechanism 3 pops out. Under the action of the centering adjustment mechanism 3, the anchor rod is located at the center axis of the hole, and the first centering limit fixation is completed.

[0038] After completing the first centering limit fixation, the clamping hoop 2 is sleeved on the anchor rod through the elastic clamping pad 5 at the other end of the anchor rod, and the centering adjustment mechanism 3 is located at the hole mouth of the hole. At this time, the centering adjustment mechanism 3 is pressed to make it pop out, so that the hole end of the anchor rod is located at the center axis of the hole. At this point, the second centering limit fixation of the anchor rod is completed; by performing two centering limit fixations on the two ends of the anchor rod, the anchor rod can be kept on the center axis of the hole at all times without external force, thereby improving the stability of the anchor rod installation to facilitate subsequent concrete pouring.

[0039] As a preferred embodiment, the centering adjustment mechanism 3 includes: four limiting slide bars 21, an adjustment pressing block 22, and a centering adjustment component 23;

[0040] The four limiting slide bars 21 are respectively slidably disposed in the four slide grooves 4; the adjusting pressing block 22 is disposed on the fixing block 1; and

[0041] One end of the centering adjustment component 23 is connected to the limiting slide rod 21 , and the other end is connected to the adjustment pressing block 22 .

[0042] It needs to be explained that by pressing the adjusting block 22, the adjusting block 22 slides down under the force, thereby releasing the movement restriction of the centering adjusting component 23, so that the limiting slide rod 21 pops out under the action of the centering adjusting component 23, and the limiting slide rod 21 is controlled by the centering adjusting component 23, so that the anchor rod is adjusted to the center axis of the hole under the clamping of the clamping hoop 2.

[0043] As a preferred embodiment, the limiting slide bar 21 includes:

[0044] A limiting rod 211 is slidably disposed in the slide slot 4 and connected to the centering adjustment component 23;

[0045] A turntable 212, one end of which is fixedly mounted on the limiting rod 211, and the other end of which is centrally provided with a groove, in which a rotating shaft is arranged; and

[0046] The limiting groove 213 is provided in the limiting rod 211 and a limiting axis is arranged therein.

[0047] It should be noted that when the centering adjustment component 23 limits it, the centering adjustment component 23 limits the limit rod 211 through the limit shaft, thereby preventing it from popping out of the slide groove; after pressing the adjustment block 22, the centering adjustment component 23 is disengaged from the limit shaft, so that under the action of the centering adjustment component 23, the limit rod 211 slides out of the slot, that is, while adjusting the anchor rod to be at the center axis of the hole, the anchor rod is fixed in the hole.

[0048] As a preferred embodiment, the centering adjustment component 23 includes:

[0049] The slide rails 231 are symmetrically arranged on both sides of the slide groove 4, one end of a slider 232 is slidably arranged in the slide groove 4, and the other end of the slider 232 is fixed on the limiting rod 211;

[0050] A compression spring 234 is provided between the slide rail 231 and the slider 232; and

[0051] The limiting rod 233 is rotatably disposed on the rotating shaft, and one end thereof abuts against the adjusting pressing block 22 , and the other end thereof abuts against the limiting shaft.

[0052] As a preferred embodiment, a torsion spring is provided at the connection between the limiting rod 233 and the rotating shaft.

[0053] It should be noted that, in the limited state, by pressing the limiting rod 233, one end of it abuts against the limit shaft and the other end abuts against the adjusting block 22. During the installation process, the torsion spring generates torque, which enables the limiting rod 233 to maintain a limited posture to prevent accidental falling off and causing failure of the limited state.

[0054] When the limiting state is released, the adjusting pressure block 22 is pressed. When the adjusting pressure block 22 slides down, it squeezes one end of the limiting rod 233, causing the limiting rod 233 to rotate around the rotating shaft, that is, the other end of the limiting rod 233 is lifted, so that the lifted end of the limiting rod 233 is released from the abutment state with the limiting shaft. After the abutment state with the limiting shaft is released, the compression spring 234 uses its elastic potential energy to make the limiting rod 211 slide out of the sliding groove quickly. Because each limiting rod 211 is under the action of the same compression spring 234, the sliding displacement of the limiting rod 211 is the same, that is, the anchor rod can be located at the center axis of the hole, and the limiting fixation of the anchor rod is completed at the same time.

[0055] As a preferred embodiment, the regulating block 22 includes:

[0056] Four slideways 223 are evenly fixed around the circumference on the fixed block 1, one end of the slide 222 is slidably set in the slide 223, and the other end of the slide 222 is fixed to the press table 221; and the limit damping blocks 224 are symmetrically fixed on both sides of the slide 223 to provide a certain sliding damping.

[0057] As a preferred embodiment, one end of the limiting rod 233 abuts against the limiting shaft, and the other end abuts against the end of the pressing platform 221; a second connecting hole is opened in the pressing platform 221 opposite to the first connecting hole, and the first connecting hole is nested and connected with the second connecting hole.

[0058] It should be noted that in the limited state, the press table 221 is at the highest point of the slideway 223, and the damping between the slide table 222 and the slideway 223 prevents the press table 221 from sliding without the action of external force;

[0059] When the restricted state needs to be released, the pressing platform 221 is squeezed / pressed to make the pressing platform 221 overcome the damping between the slide 222 and the slideway 223 and slide down through the slideway 223. During the sliding process, the pressing platform 221 causes the restricting rod 233 to rotate, thereby releasing the restriction on the limiting rod 211.

[0060] In specific implementation, when installing the anchor rod, first install one end of the anchor rod in the clamping hoop 2 through the elastic clamping pad 5, and perform preliminary centering limit clamping. After completing the above operations, slowly put this end into the hole. When the anchor rod is completely placed in the hole, apply pressure to the anchor rod, thereby pressing the adjustment block 22, so that the centering adjustment component 23 releases the limitation on the limit rod 211, that is, the limit rod 211 pops out of the slide groove, and under the action of the limit rod 211, the anchor rod is placed at the center axis of the hole, and the centering limit fixation is completed.

[0061] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
