Description

Technical Field

[0001] This utility model relates to the technical field of construction engineering, and specifically relates to an anchor rod construction device. Background Technique

[0002] An anchor rod construction device is a special equipment used to install anchor rods in rock or soil. An anchor rod is a structural element used to reinforce and stabilize rock and soil masses. The anchor rod construction device plays an important role in civil engineering, mining engineering, tunnel engineering, slope support, foundation pit support and other fields, especially in occasions where rock and soil masses need to be reinforced and stabilized.

[0003] However, during actual use, the existing anchor rod construction device rotates the anchor rod head into the mountain body through a rotating machine. After reaching the destination, mortar needs to be injected into the anchor rod and then injected into the mountain body through the hollow interior of the anchor rod to improve the strength of the mountain and prevent the mountain from collapsing.

[0004] However, when the existing anchor rod construction device pushes the anchor rod into the mountain body, it is necessary to push the mortar into the head through the interior of the anchor rod. Since there are holes in the head that communicate with the interior of the anchor rod, the mortar can be discharged from the holes. When the head rotates at high speed, it may cause sand and gravel to enter the interior of the anchor rod through the holes in the head, resulting in blockage inside the anchor rod. The grouting material cannot completely fill the anchor rod hole, resulting in insufficient bonding between the anchor rod and the surrounding medium, affecting the bearing capacity and stability of the anchor rod. Therefore, we propose an anchor rod construction device. Content of the Utility Model

[0005] One technical problem to be solved by this application is: how to design an anchor rod construction device that can prevent sand and gravel from entering the interior of the anchor rod through the holes in the head.

[0006] To solve the above technical problem, the embodiment of this application provides an anchor rod construction device, including an anchor rod body, a connecting cylinder arranged on the inner wall of the anchor rod body, and a head arranged inside the anchor rod body, and further including:

[0007] A rotating ring, the rotating ring is arranged inside the connecting cylinder;

The slider is movably disposed on the inner wall of the ring groove. The outer surface of the rotating ring is movably disposed on the inner wall of the fixed cylinder.

[0011] In some embodiments, an inclined groove is formed on the inner wall of the end face of the fixed cylinder. A sliding rod is provided on the side of the baffle plate close to the inclined groove. The sliding rod is movably disposed on the inner wall of the inclined groove. An elastic force assembly for controlling the opening and closing of the baffle plate by centrifugal force is provided on the outer surface of the rotating ring.

[0012] In some embodiments, the elastic force assembly includes a connecting rod. The bottom end of the connecting rod is disposed on the outer surface of the rotating ring. An arc-shaped groove is formed on the outer surface of the fixed cylinder. A connecting groove communicating with the arc-shaped groove is formed on the inner wall of the connecting cylinder. The connecting rod is movably disposed inside the arc-shaped groove.

[0013] In some embodiments, an iron bead is provided at the top end of the connecting rod. The iron bead is movably disposed inside the connecting groove. A tension spring is disposed on the inner wall of the connecting groove. The other end of the tension spring is disposed on the outer surface of the iron bead.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Embodiment 1

[0031] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0032] An anchor construction device, including a bolt body 1, a connecting cylinder 3 provided on the inner wall of the bolt body 1, and a rotating head 2 provided inside the bolt body 1, further including:

[0033] A rotating ring 6, and the rotating ring 6 is provided inside the connecting cylinder 3;

[0034] Baffle plates 5, there are multiple baffle plates 5, and the multiple baffle plates 5 are circumferentially distributed at the center of the rotating ring 6 and are arranged on the end face of the rotating ring 6 to prevent sand and gravel from entering the interior of the anchor rod body 1 through the holes and grooves of the rotating head 2;

[0035] Opening and closing assembly 7, the opening and closing assembly 7 is arranged inside the connecting cylinder 3 and is used to control the opening and closing of the multiple baffle plates 5.

[0036] The opening and closing assembly 7 includes a fixed cylinder 71 arranged on the inner wall of the connecting cylinder 3. A ring groove 73 is formed on the end face of the rotating ring 6. A slider 72 is arranged on the side of the baffle plate 5 close to the rotating ring 6. The slider 72 is movably arranged on the inner wall of the ring groove 73. The outer surface of the rotating ring 6 is movably arranged on the inner wall of the fixed cylinder 71. In this way, by moving the rotating ring 6, the ring groove 73 on the end face of the rotating ring 6 can be rotated. Since the ring groove 73 is hexagonal, the slider 72 can be driven to move on the inner wall of the ring groove 73.

[0037] An inclined groove 75 is formed on the inner wall of the end face of the fixed cylinder 71. A sliding rod 74 is arranged on the side of the baffle plate 5 close to the inclined groove 75. The sliding rod 74 is movably arranged on the inner wall of the inclined groove 75. An elastic force assembly 8 for controlling the opening and closing of the baffle plate 5 by centrifugal force is arranged on the outer surface of the rotating ring 6. The sliding rod 74 and the inclined groove 75 are arranged to play a guiding role, so that the baffle plate 5 can connect the rotating cylinder and the interior of the anchor rod body 1.

[0038] The elastic force assembly 8 includes a connecting rod 84. The bottom end of the connecting rod 84 is arranged on the outer surface of the rotating ring 6. An arc-shaped groove 82 is formed on the outer surface of the fixed cylinder 71. A connecting groove 81 communicated with the arc-shaped groove 82 is formed on the inner wall of the connecting cylinder 3. The connecting rod 84 is movably arranged inside the arc-shaped groove 82.

[0039] An iron bead 85 is arranged at the top end of the connecting rod 84. The iron bead 85 is movably arranged inside the connecting groove 81. A tension spring 83 is arranged on the inner wall of the connecting groove 81. The other end of the tension spring 83 is arranged on the outer surface of the iron bead 85. Mainly through the weight of the iron bead 85, the centrifugal force is increased. Therefore, the baffle plate 5 can be closed during the overall rotation. When there is no rotation, it can be reset under the drive of the tension spring 83 to open the baffle plate 5.

[0040] A diversion cylinder 4 is arranged on the inner wall of the anchor rod body 1. The end face of the diversion cylinder 4 is arranged inside the fixed cylinder 71. The diversion cylinder 4 is arranged to allow the mortar to pass through the interior of the fixed cylinder 71 and the rotating ring 6, rather than directly acting on the end face of the fixed cylinder 71.

[0041] When using this device, first drill the rotating head 2 into the rock by rotating the anchor rod body 1. When rotating the anchor rod body 1, since the iron bead 85 is a solid iron ball, the connecting groove 81 can drive the deformation of the tension spring 83, so that it reaches the inner wall of the connecting groove 81. At the same time, due to the action of the iron bead 85, the connecting rod 84 arranged on the outer surface of the iron bead 85 can drive the rotating ring 6 to rotate inside the fixed cylinder 71. For this reason, a plurality of baffles 5 can be driven to block the connection between the rotating ring 6 and the fixed cylinder 71. Therefore, when sand and gravel enter through the hole groove of the rotating head 2, they will be blocked by the baffle 5. When grouting is required, the anchor rod body 1 stops rotating. At this time, due to the absence of centrifugal force, the iron bead 85 will be pulled back to its original position by the tension spring 83. Therefore, it drives the connecting rod 84 arranged on the outer surface to move. The connecting rod 84 drives the rotating ring 6 arranged at the bottom end to rotate. The rotating ring 6 drives the ring groove 73 opened on the end face to rotate. For this reason, the ring groove 73 can drive a plurality of sliding blocks 72 arranged inside to move. The sliding rod 74 arranged on the other side of the baffle 5 will slide inside the inclined groove 75, so as to open a plurality of baffles 5, so that the mortar inside the anchor rod body 1 can enter the rotating ring 6 through the inside of the fixed cylinder 71, and finally spray out from the hole groove of the rotating head 2.

[0042] Embodiment 2

[0043] Please refer to Figure 8-9 , this utility model provides a technical solution:

[0044] Different from Embodiment 1, scraping rings 9 are arranged on the inner walls of the fixed cylinder 71 and the rotating ring 6 respectively. The adjacent end faces of the two scraping rings 9 are movably arranged on both sides of the baffle 5 respectively. The end face of the scraping ring 9 close to the baffle 5 is sharp.

[0045] When the baffle 5 needs to be opened or closed, both sides of the baffle 5 will move from the end face of the scraping ring 9. The scraping ring 9 will scrape off the mortar on both sides of the baffle 5, preventing the mortar from adhering to the baffle 5 and causing the baffle 5 to adhere during segmented use, and preventing the whole from getting stuck.
