Abstract
Description
Technical Field
[0001] This utility model relates to the field of anchor bolt support technology, specifically to a resin anchoring agent installation device. Background Technology
[0002] The current anchoring operation process during underground mine or traffic tunnel construction is as follows: First, drill holes of the appropriate length and diameter are made at the top of the tunnel; second, the construction worker pushes one or more resin anchors into the hole with one hand, while using the anchor rod to hold the tail of the anchor to prevent it from falling; then, the construction worker slowly pushes the resin anchor into the appropriate depth of the hole with the anchor rod; the resin anchor is stirred evenly with a mixer; after waiting for a certain period of time, the tray is placed on top and the nuts are tightened.
[0003] However, the following problems were found during actual construction: In the construction of anchor bolt support on the top of the roadway, since the borehole is at the top of the roadway, when placing the resin anchoring agent into the borehole, the operators usually need to stand at a higher position with the help of ladders and other tools. This construction is not only inconvenient but also unsafe. Moreover, during the installation of the anchoring agent, the anchoring agent that enters the borehole first is not only prone to slipping but also difficult to fix at the specified depth, which can easily lead to waste of anchoring agent or installation failure.
[0004] Therefore, there is an urgent need for an auxiliary installation device to solve the above problems. Utility Model Content
[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a resin anchoring agent installation device, which solves the technical problem in the prior art that it is not easy to place the anchoring agent into the borehole during roadway top support operations.
[0006] According to one aspect, at least one embodiment of the present invention provides a resin anchoring agent installation device, including an installer having an installation cavity inside the installer for holding the anchoring agent, the outer periphery of the installer having a plurality of elastic wings configured to bend and engage with the inner wall of the borehole after entering the borehole, and the top of the installer having an opening communicating with the installation cavity for a clamp of the anchoring agent to pass through and engage, thereby fixing the end of the anchoring agent.
[0007] As a further technical solution, the installer also has a protective surface located between the opening and the elastic wing.
[0008] As a further technical solution, the protective surface is conical and gradually slopes downward toward the side away from the axis of the mounter, and there is a clearance gap between the elastic wings.
[0009] As a further technical solution, the outer periphery of the installer also has several release grooves that communicate with the mounting cavity.
[0010] As a further technical solution, a protective sleeve is also included, one end of which is connected to the outer periphery of the installer, and the protective sleeve is used to cover the outside of the anchoring agent.
[0011] As a further technical solution, a connector is also included, one end of which is connected inside the protective sleeve, and the other end has a threaded portion for connection with the anchor bolting machine.
[0012] As a further technical solution, the outer periphery of the installer also has a limiting ring portion, which is located on one side of the elastic wing. The limiting ring portion is configured to abut against the end face of the protective sleeve to limit the connection position of the protective sleeve.
[0013] As a further technical solution, the connector has a screwing part, and the outer side wall of the screwing part has two symmetrical planes.
[0014] As a further technical solution, the cone half-angle of the protective surface is 10°-30°.
[0015] As a further technical solution, the angle between the flexible wing and the axis of the installer after bending is 35°-55°.
[0016] The beneficial effects of this utility model are as follows:
[0017] In this invention, the installer, along with the anchoring agent, is stably fixed inside the borehole, solving the problems of anchoring agent slippage and difficulty in fixing it at the specified depth. The overall structure of the installer eliminates the need for manual handling of the anchoring agent, reducing the risk of high-altitude operations for workers. Simultaneously, the structural design ensures the anchoring agent remains stable at the specified depth, reducing waste and the probability of installation failure. Using a long rod to push the installer instead of the anchoring agent, and due to the open design, it can press against the borehole wall at the deepest point, providing effective feedback without compressing or damaging the anchoring agent, preventing premature leakage. The installer also provides some protection for the anchoring agent during insertion, preventing falling debris from damaging it. Attached Figure Description

[0030] like Figures 1-3 As shown, this invention illustrates a resin anchoring agent 2 installation device according to one embodiment of the present invention, including an installer 1, an installation cavity 11 inside the installer 1, the resin anchoring agent 2 being packaged in a manner similar to a sausage, the contour of the installation cavity 11 being designed to fit the resin anchoring agent 2, facilitating the insertion of one end of the resin anchoring agent 2 into the installation cavity 11, a ring of elastic wings 12 being provided on the outer peripheral wall of the installer 1, the elastic wings 12 extending along the axial direction of the installer 1, initially forming a certain angle with the axis of the installer 1, the elastic wings 12 being elastic and capable of elastic deformation, the top of the installer 1 having an opening 13 communicating with the installation cavity 11, the contour of the opening 13 being adapted to the clamp 21 of the anchoring agent 2, the clamp 21 being able to pass through the opening 13 and be limited by the edge of the opening 13.
[0031] The design principle is as follows: First, insert one end of the resin anchor 2 into the mounting cavity 11. Then, pull out the clamp 21 of the resin anchor 2 from the opening 13, so that it is locked onto the end face of the opening 13 to achieve initial positioning. Afterwards, glue can be added between the resin anchor 2 and the inner wall of the mounting cavity 11 to strengthen the fixation. Then, the resin anchor 2 together with the installer 1 is inserted into the drill hole. For example, a long rod is used to hold the installer 1 and insert the whole into the drill hole. The elastic wing 12 bends under the pressure of the inner wall of the drill hole. The deformation of the elastic wing 12 in the drill hole is used to lock the inner wall of the drill hole. Combined with the limiting of the clamp 21 by the opening 13, the resin anchor 2 can be fixed in real time at any position in the drill hole. There is no need to hold the resin anchor 2 while inserting the anchor rod, making the operation simpler and less labor-intensive.
[0032] This embodiment provides a resin anchor 2 installation device. The installer 1, along with the anchor 2, is stably fixed inside the borehole, solving the problems of the anchor 2 easily slipping and being difficult to fix at the specified depth. The overall structure of the installer 1 eliminates the need for manual handling of the anchor 2, reducing the risk of high-altitude operations for operators. Simultaneously, the structural design ensures the anchor 2 remains stable at the specified depth, reducing the probability of anchor 2 waste and installation failure. Using a long rod to push the installer 1 instead of the anchor 2, and due to the opening 13, it can press against the borehole wall when reaching the deepest point, providing effective feedback without compressing or damaging the anchor 2, preventing premature leakage. The installer 1 also provides some protection for the anchor 2 during insertion, preventing falling debris from damaging it.
[0033] refer to Figures 1-3 In some embodiments, a protective surface 14 is also provided on the outer periphery of the installer 1. In this embodiment, the protective surface 14 helps guide the falling rocks downwards and out between the elastic wings 12, preventing them from getting stuck between the installer 1 and the inner wall of the borehole, thus affecting the continued deepening of the installer 1.
[0034] refer to Figures 1-3 In some embodiments, the protective surface 14 is preferably conical, with its generatrix extending from the edge of the opening 13 toward the direction of the elastic wing 12. In this embodiment, the conical surface is more conducive to the falling rocks falling out of the clearance gap 121. In addition, the clearance gap 121 between the elastic wings 12 ensures that each elastic wing 12 can be bent independently, avoiding deformation restriction caused by the mutual compression of adjacent elastic wings 12, and ensuring the clamping effect of the elastic wings 12 on the inner wall of the borehole.
[0035] refer to Figures 1-3 In some embodiments, the outer periphery of the installer 1 is also provided with a release groove 15, which allows the anchoring agent 2 to be quickly released into the borehole after the subsequent anchor rod enters and destroys the resin anchoring agent 2.
[0036] refer to Figures 1-3 In some embodiments, a resin anchor 2 installation device further includes a protective sleeve 3, one end of which is connected to the outer periphery of the installer 1, and the inner spatial contour of the protective sleeve 3 is adapted to the outer contour of the anchor 2, so that the anchor 2 is located inside the protective sleeve 3.
[0037] Its design principle is as follows: the protective sleeve 3 covers the outside of the anchoring agent 2, isolating the anchoring agent 2 from the inner wall of the borehole and preventing the anchoring agent 2 from directly contacting the inner wall of the borehole. The working process is as follows: after the anchoring agent 2 is placed into the installation cavity 11 and fixed through the opening 13, the protective sleeve 3 covers the outside of the anchoring agent 2; the protective sleeve 3 is directly pushed to send the whole into the borehole, thereby achieving isolation and protection of the anchoring agent 2.
[0038] This embodiment provides a resin anchoring agent 2 installation device. A protective sleeve 3 facilitates the easy and labor-saving insertion of the installer 1 and the anchoring agent 2 into the borehole, while also protecting the anchoring agent 2. The protective sleeve 3 covers the outside of the anchoring agent 2, preventing friction or collision between the anchoring agent 2 and the borehole wall during entry, thus protecting the integrity of the anchoring agent 2. The connection between the protective sleeve 3 and the installer 1 encloses the anchoring agent 2 in a relatively enclosed space. Combined with the holding of the anchoring agent 2 by the installation cavity 11 and the limiting of the clamp 21 by the opening 13, this further reduces the positional displacement of the anchoring agent 2 due to external collisions, ensuring that the anchoring agent 2 stably reaches the designated depth. The protective sleeve 3 reduces the risk of failure of the anchoring agent 2 due to physical damage, improving the installation success rate. Furthermore, the protective sleeve 3 acts on the installer 1; when reaching the deepest point of the borehole, the protective sleeve 3 applies force to the installer 1 to determine if it is the deepest point, without damaging the anchoring agent 2.
[0039] refer to Figures 1-4 In some embodiments, a resin anchoring agent 2 installation device further includes a connector 4, one end of which is fixedly connected to the inside of the protective sleeve 3, and the outer periphery of the other end is provided with a threaded portion 41, the thread specification of which is adapted to the connection interface of the anchor bolt machine.
[0040] Its design principle is as follows: the connector 4 is connected to the anchor bolting machine via the threaded part 41, allowing the power of the anchor bolting machine to be transmitted to the protective sleeve 3 and the installer 1 through the connector 4, thus achieving mechanized operation. The working process is as follows: connect one end of the connector 4 to the protective sleeve 3, and the other end to the anchor bolting machine via the threaded part 41; start the anchor bolting machine, which drives the protective sleeve 3, the installer 1, and the anchoring agent 2 to move through the connector 4, sending them to the designated position in the borehole.
[0041] This embodiment provides a resin anchoring agent 2 installation device. Through the connector 4, it enables mechanical replacement of manual pushing of the anchoring agent 2, reducing the time and risk of high-altitude operations for operators. The cooperation between the connector 4, the protective sleeve 3, and the installer 1 makes the insertion process of the anchoring agent 2 smoother, avoiding the displacement of the anchoring agent 2 caused by uneven force during manual pushing, ensuring that the anchoring agent 2 accurately reaches the designated depth. Mechanized operation combined with structural fixation further improves construction efficiency and installation accuracy.
[0042] refer to Figures 1-4 In some embodiments, the mounter 1 also has a limiting ring 16, which protrudes outward along the outer periphery of the mounter 1 and is located below the elastic wing 12; when the protective sleeve 3 is connected to the outer periphery of the mounter 1, the end face of the protective sleeve 3 abuts against the limiting ring 16.
[0043] Its design principle is as follows: by abutting the end face of the protective sleeve 3 with the limiting ring 16, the movement of the protective sleeve 3 along the axial direction of the installer 1 is restricted, ensuring that the connection position of the protective sleeve 3 is fixed. The working process is as follows: the protective sleeve 3 is inserted along the outer periphery of the installer 1 until the end face of the protective sleeve 3 abuts the limiting ring 16. At this time, the connection position of the protective sleeve 3 is limited. Adhesive is added between the two to complete the fixation of the protective sleeve 3 and the installer 1.
[0044] This embodiment provides a resin anchoring agent 2 installation device. The limiting ring 16 positions the protective sleeve 3 on the installer 1, facilitating the connection between the protective sleeve 3 and the installer 1. This improves installation efficiency.
[0045] refer to Figures 1-4 In some embodiments, the connector 4 also has a screwing part 42, which is located in the middle of the connector 4 and has two symmetrical planes 421 on its outer periphery, which are arranged in parallel.
[0046] The design principle is as follows: the two symmetrical planes 421 of the screwing part 42 can be used with tools such as wrenches. By applying torque to the screwing part 42 through the tool, the connector 4 can be tightened or disassembled. The working process is as follows: when the connector 4 is connected to the protective sleeve 3 or the anchor bolt machine, the wrench is inserted between the two planes 421 of the screwing part 42, and the connector 4 is rotated by the tool to tighten the threaded part 41 of the connector 4 with the corresponding connection interface; when disassembling, the tool is rotated in the opposite direction to disengage the connector 4 from the connection interface.
[0047] This embodiment provides a resin anchor 2 installation device. The connector 4 can be quickly installed and removed through the screwing part 42, which improves the overall installation efficiency of the installation device.
[0048] refer to Figures 1-4In some embodiments, the protective surface 14 is conical with a cone half-angle of 10°-30°, that is, the angle between the generatrix of the protective surface 14 and the axis of the mount 1 is 10°-30°.
[0049] This embodiment provides a resin anchoring agent 2 installation device. By limiting the angle, it provides parameters with better guiding effect, which can relatively reduce the situation where gravel and rocks get stuck on the installer 1.
[0050] refer to Figures 1-4 In some embodiments, the angle between the flexible wing 12 and the axis of the mount 1 after bending is 35°-55°.
[0051] This embodiment provides a resin anchor 2 installation device. By limiting the angle, it not only ensures the clamping stability of the installer 1 in the drill hole and prevents the anchor 2 from slipping, but also avoids structural damage to the elastic wing 12 due to excessive deformation, thus extending the service life of the device.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
