Description

Technical Field

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

[0002] As an important engineering material, an anchor rod generates stress opposite to the anchor rod through the friction and cohesion between the soil or rock, effectively preventing the soil from moving due to the load, thereby enhancing the stability and safety performance of the structure. In soft soil areas, due to the instability of the soil and low bearing capacity, the anchor rod can increase the inherent strength of the soft soil through the action of prestressed tension, thereby slowing down or preventing the collapse and sliding of the soil and making it more stable.

[0003] In the prior art, most of the anchor rod fixing devices simply use an expansion shell head to ensure the stable state of the anchor rod before grouting. However, when in an environment with poor soil hardness, the fixing effect of the expansion shell head is greatly reduced, resulting in an increase in the instability of the anchor rod itself before grouting. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the above equipment is in use, due to the existing anchor rod fixing device in an environment with poor soil hardness, the instability of the anchor rod itself before grouting is enhanced, and an anchor rod fixing device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an anchor rod fixing device, including an anchor rod fixing mechanism, and an anchor plate reinforcement mechanism is movably sleeved on the outer surface wall of the anchor rod fixing mechanism;

[0006] The anchor rod fixing mechanism includes a hollow anchor rod, a steel expansion shell head is fixedly sleeved on the outer surface wall of the hollow anchor rod, a first thread groove is opened on one side of the outer wall of the hollow anchor rod, a soil-breaking drill bit is threadedly connected to the inner surface wall of the first thread groove, a plurality of grouting holes are opened on the outer surface wall of the soil-breaking drill bit, a plurality of first holes are opened on the inner surface wall of the hollow anchor rod, and fastening pins are movably inserted into the inner surface walls of the plurality of first holes.

[0007] Preferably, a push ellipse block is movably inserted into the inner surface wall of the hollow anchor rod, a connecting rod is fixedly connected to the outer surface wall of the push ellipse block, and a handle is threadedly connected to the outer surface wall of the connecting rod.

[0008] Preferably, a nut is threadedly connected to the outer surface wall of the hollow anchor rod, and a gasket is movably sleeved on the outer surface wall of the hollow anchor rod.

[0009] Preferably, the anchor plate reinforcement mechanism includes an anchor plate, and a second hole is opened on one side of the outer wall of the anchor plate.

[0010] Preferably, four second thread grooves are formed on one side of the outer wall of the anchor plate.

[0011] Preferably, the inner walls of the four second thread grooves are all threadedly connected with fixing bolts.

[0012] Preferably, the outer wall of the hollow anchor rod is movably inserted into the inner wall of the second hole.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, under the action of the anchor fixing mechanism, a plurality of first holes are opened on the surface of the hollow anchor, and the fastening pins inside the first holes are pushed out of the first holes and inserted into the soil by using the pushing ellipse, so that the anchor is firmly fixed inside the borehole. The plurality of fastening pins inserted into the soil inside the inner wall of the borehole further increase the friction between the anchor and the soil, ensuring that the anchor can maintain its own stability for a long time before grouting. At the same time, under the action of the fastening pins, the connection state between the anchor and the soil after grouting is further strengthened, which has strong practicality and makes the anchor more stable.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1, as Figures 1-4 As shown, the utility model provides an anchor rod fixing device, comprising an anchor rod fixing mechanism 1, and an outer wall movable sleeve of the anchor rod fixing mechanism 1 is provided with an anchor pad reinforcement mechanism 2;

[0026] The anchor fixing mechanism 1 includes a hollow anchor 101, the outer wall of which is fixedly sleeved with a steel expansion head 102, a first thread groove 103 is provided on one side of the outer wall of the hollow anchor 101, the inner wall of the first thread groove 103 is threadedly connected with a ground-breaking drill bit 104, the outer wall of the ground-breaking drill bit 104 is provided with a plurality of grouting holes 105, the inner wall of the hollow anchor 101 is provided with a plurality of first holes 106, the inner walls of the plurality of first holes 106 are movably inserted with fastening pins 107, the inner wall of the hollow anchor 101 is movably inserted with a push-pull ellipse 108, the outer wall of the push-pull ellipse 108 is fixedly connected with a connecting rod 109, the outer wall of the connecting rod 109 is threadedly connected with a handle 110, the outer wall of the hollow anchor 101 is threadedly connected with a nut 111, and the outer wall of the hollow anchor 101 is movably sleeved with a gasket 112.

[0027] The effect achieved by the entire Embodiment 1 is that under the action of the anchor rod fixing mechanism 1, by fixedly sleeving a steel expansion shell head 102 on the outer wall of the hollow anchor rod 101, the friction between the anchor rod 101 and the inner wall of the drill hole is increased by using the steel expansion shell head 102. At the same time, a first thread groove 103 is opened on one side of the outer wall of the hollow anchor rod 101, and the earth-breaking drill bit 104 is connected to the first thread groove 103 by thread connection. A plurality of grouting holes 105 are opened on the outer wall of the earth-breaking drill bit 104. By using the grouting holes 105, the mortar injected into the hollow anchor rod 101 flows into the drill hole through the grouting holes 105 until it overflows from the other end of the hollow anchor rod 101. A plurality of first holes 106 are opened on the inner wall of the hollow anchor rod 101, and fastening pins 107 are movably inserted into the inner walls of the plurality of first holes 106. By pulling the handle 110, the push ellipse block 108 fixedly connected to one side of the outer wall of the connecting rod 109 is pulled out to the left. During the pulling-out process, the plurality of fastening pins 107 are extruded out of the hollow anchor rod 101 through the opened first holes 106 under the action of the push ellipse block 108 and inserted into the inner wall of the drill hole, realizing the fixing effect of the anchor rod. The use of the plurality of fastening pins 107 inserted into the soil inside the inner wall of the drill hole further increases the friction between the hollow anchor rod 101 and the soil, ensuring that the hollow anchor rod can maintain its own stability for a long time before grouting. At the same time, under the action of the fastening pins 107, the connection state between the hollow anchor rod 101 and the soil after grouting is further strengthened, with strong practicability and making the anchor rod more stable.

[0028] Embodiment 2, as Figures 2-4 shown, the anchor plate reinforcement mechanism 2 includes an anchor plate 201. A second hole 202 is opened on one side of the outer wall of the anchor plate 201. Four second thread grooves 203 are opened on one side of the outer wall of the anchor plate 201. Fixing bolts 204 are threadedly connected to the inner walls of the four second thread grooves 203. The outer wall of the hollow anchor rod 101 is movably inserted into the inner wall of the second hole 202.

[0029] The effect achieved by the entire Embodiment 2 is that under the action of the anchor plate reinforcement mechanism 2, by opening a second hole 202 on one side of the outer wall of the anchor plate 201 and four second thread grooves 203 on one side of the outer wall of the anchor plate 201, the outer walls of the four fixing bolts 204 are threadedly connected to the inner walls of the second thread grooves 203, and the four fixing bolts 204 are fixed in the soil through the four second thread grooves 203, thereby improving the stability of the entire anchor rod fixing device in this way.

[0030] Working principle: First, a steel expanding shell head 102 is fixedly sleeved on the outer wall of the hollow anchor rod 101 to increase the friction between the anchor rod 101 and the inner wall of the drill hole. At the same time, a first thread groove 103 is opened on one side of the outer wall of the hollow anchor rod 101, and the earth-breaking drill bit 104 is connected to the first thread groove 103 by thread connection. Multiple grouting holes 105 are opened on the outer wall of the earth-breaking drill bit 104, and the mortar injected into the hollow anchor rod 101 flows into the drill hole through the grouting holes 105 until it overflows from the other end of the hollow anchor rod 101. Multiple first holes 106 are opened on the inner wall of the hollow anchor rod 101, and fastening pins 107 are movably inserted into the inner walls of the multiple first holes 106. By pulling the handle 110, the push ellipse block 108 fixedly connected to one side of the outer wall of the connecting rod 109 is pulled out to the left. During the pulling process, the multiple fastening pins 107 are extruded out of the hollow anchor rod 101 through the opened first holes 106 under the action of the push ellipse block 108 and inserted into the inner wall of the drill hole to realize the fixing effect of the anchor rod. The multiple fastening pins 107 inserted into the soil inside the inner wall of the drill hole further increase the friction between the hollow anchor rod 101 and the soil, ensuring that the hollow anchor rod can maintain its own stability for a long time before grouting. At the same time, under the action of the fastening pins 107, the connection state between the hollow anchor rod 101 and the soil after grouting is further strengthened, which has strong practicability and makes the anchor rod more stable. At the same time, a nut 111 is threadedly connected to the outer wall of the hollow anchor rod 101, and an anchor backing plate 201 is in contact between the nut 111 and the soil. The nut 111 makes the hollow anchor rod 101 in close contact with the soil. A second hole 202 is opened on one side of the outer wall of the anchor backing plate 201, and four second thread grooves 203 are opened on one side of the outer wall of the anchor backing plate 201. The outer walls of the four fixing bolts 204 are threadedly connected to the inner walls of the second thread grooves 203, and the four fixing bolts 204 are fixed in the soil through the four second thread grooves 203. In this way, the stability of the entire anchor rod fixing device is improved. Finally, the mortar injected into the hollow anchor rod 101 flows into the drill hole through the grouting holes 105 until it overflows from the other end of the hollow anchor rod 101.

[0031] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
