Technical Field

[0001] The invention relates to the technical field of coal mine tunnel construction, and in particular to a roof anchoring agent hole-entering device and a roof anchoring agent pushing method. Background Art

[0002] Mining anchors are a type of material widely used in mining engineering to reinforce and stabilize rock mass or underground engineering structures. In the mining process, mining anchors play a very important role, which can effectively enhance the bearing capacity of rock, prevent rock collapse and collapse, and ensure the safety and efficiency of mining production.

[0003] Before anchoring, support design is required to determine the anchoring agent's layout location, quantity, depth and other parameters. Support design should take into account the stability and safety of the engineering structure to avoid accidents. The operation technology of pushing the anchoring agent into the rock mass and fixing it includes drilling, grouting, anchor installation and other steps, which requires the operator to have professional skills and experience to ensure that the anchoring agent can be effectively fixed in the rock mass.

[0004] When constructing roof anchors in coal mine tunnels, anchoring agents need to be delivered into the anchor boreholes. Often, two or more anchors are delivered into the holes. Since the texture of the anchors is relatively soft, when multiple anchors are delivered into the anchor boreholes one by one, the anchors often bend and cannot be delivered into the anchor boreholes. Summary of the invention

[0005] The purpose of the present invention is to provide a roof anchor hole entry device and a roof anchor pushing method that can increase the anchor hole entry speed, so as to solve the technical problem in the background technology that the anchor is soft and difficult to be sent into the anchor hole when constructing roof anchors in coal mines.

[0006] To achieve the above-mentioned purpose, the present invention provides, on the one hand, a roof anchor hole entry device, comprising a PVC tube for placing one or more sections of anchors, wherein both ends of the PVC tube are not sealed, and when in use, the anchor drill bit pushes upward against the lower anchor inside the PVC tube, and an opening passes through one side of the tube wall of the PVC tube from top to bottom, and the width of the opening is smaller than the diameter of the anchor and larger than the diameter of the anchor drill bit.

[0007] As a further solution of the present invention, the PVC pipe also includes a pushing gasket for pushing the anchor, and a groove connected to the top of the anchor drill bit is provided on one side of the pushing gasket, and the shape of the groove is adapted to the shape of the top of the anchor drill bit, and the other side of the pushing gasket is connected to the anchor.

[0008] As a further solution of the present invention, the size of the pushing gasket is smaller than the diameter of the PVC pipe.

[0009] As a further solution of the present invention, the PVC pipe also includes a pushing gasket for pushing the anchor, and one side of the pushing gasket is provided with a buckle connected to the top of the anchor drill bit, and the shape of the buckle is adapted to the top shape of the anchor drill bit, and the other side of the pushing gasket is connected to the anchor.

[0010] In another aspect, the present invention provides a method for pushing a roof anchoring agent, comprising:

[0011] After the anchor holes are obtained by drilling anchor holes in the construction roof, one or more anchoring agents are loaded into any roof anchoring agent insertion device as described in any one of claims 1 to 4;

[0012] The anchor drilling machine is started, and an anchoring agent injection device loaded with anchoring agent is sent into the anchor hole;

[0013] After the anchoring agent is delivered to the designated position, the anchoring agent entry device is lowered and recovered.

[0014] As a further solution of the present invention, the anchor drilling machine is started and an anchoring agent injection device loaded with anchoring agent is sent into the anchor hole, comprising:

[0015] Fix the top of the anchor drill bit with the groove of the push pad of the anchoring agent hole-entering device;

[0016] The anchor drilling machine is started, and the pushing gasket of the anchor hole feeding device pushes the anchor into the anchor hole, and at the same time, the PVC pipe is pushed into the anchor hole.

[0017] As a further solution of the present invention, the anchor drilling machine is started and an anchoring agent injection device loaded with anchoring agent is sent into the anchor hole, comprising:

[0018] Fix the top of the anchor drill bit with the buckle of the push pad of the anchoring agent hole entry device;

[0019] The anchor drilling machine is started, and the pushing gasket of the anchor hole feeding device pushes the anchor into the anchor hole, and at the same time, the PVC pipe is pushed into the anchor hole.

[0020] As a further solution of the present invention, after the anchoring agent is delivered to the designated position, the anchoring agent hole-entering device is dropped and recovered, comprising:

[0021] After the anchoring agent is delivered to the designated position, the PVC pipe is loosened and the PVC pipe is separated from the anchor drill bit through one side of the through opening.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] The top plate anchoring agent hole-entering device in this embodiment includes a PVC tube for placing one or more sections of anchoring agent, and both ends of the PVC tube are not sealed. When in use, the anchor drill bit pushes upward against the lower anchoring agent inside the PVC tube, and one side of the tube wall of the PVC tube passes through the opening from top to bottom, and the opening width is less than the anchoring agent diameter and greater than the anchor drill bit diameter. The top plate anchoring agent hole-entering device can solve the problem that the anchoring agent is soft and difficult to be sent into the anchor drilling hole when the top plate anchor is constructed in a coal mine. The top plate anchoring agent hole-entering device can ensure that the anchoring agent fully fills the anchor hole and exerts the expected consolidation effect. This helps to improve the safety and stability of the mine and ensure the normal progress of mining operations. The anchoring agent hole-entering device is suitable for various types of geological environments and engineering construction scenes, and can be applied to different types of anchor drilling holes, with strong applicability and flexibility. By using a notched anchoring agent hole-entering device to push the anchoring agent, the anchoring agent hole-entering speed can be increased, thereby improving the progress of anchor construction. Using an anchoring agent injection device to push the anchoring agent into the anchor rod drill hole is an efficient, accurate, safe and cost-saving construction method. It can not only improve work efficiency and quality, but also effectively ensure construction safety and stability, and provide a good foundation for long-term use.

[0024] Since the texture of the anchor is relatively soft, the contact area with the anchor can be increased by providing a pushing gasket, thereby preventing the anchor drill bit from directly contacting the anchor and causing deformation of the anchor; and by providing a structure adapted to the top of the anchor drill bit on one side of the pushing gasket, the pushing gasket and the anchor drill bit can be effectively connected, and the anchor can be pushed smoothly when in use. In the case of pushing multiple sections of anchor, the anchor can be pushed to the designated position of the anchor hole more effectively, avoiding deformation and bending of the anchor during the pushing process.

[0032] In order to enable persons skilled in the art to better understand the technical solutions in one or more embodiments of this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below in conjunction with the drawings in one or more embodiments of this specification. Obviously, the described embodiments are only one or more partial embodiments of this specification, rather than all embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this document.

[0033] It should be noted that, in the absence of conflict, one or more embodiments and features in the embodiments in this specification can be combined with each other. One or more embodiments of this specification will be described in detail below with reference to the drawings and in combination with the embodiments.

[0034] Mining anchor is a material used to fix anchor rods or anchor cables. The anchor is sent into the anchor hole through the anchor hole device, which can strengthen the soil support: after solidification, the mining anchor can form a strong bond with the surrounding soil, increase the support capacity of the soil, and improve the overall stability of the geological body. Increase the tensile strength of the anchor: after the anchor is solidified, the anchor can be tightly connected to the rock or soil, effectively improve the tensile strength of the anchor, and prevent it from shifting or falling off due to force. Improve the bonding force between the surrounding rock and the anchor: during the solidification process, the mining anchor will bond with the rock or soil to form a solid consolidation body, increase the bonding force between the surrounding rock and the anchor, and improve the stability of the anchor. Prevent loosening and sliding: by injecting the anchor into the anchor hole and filling the pores, the loosening and sliding of the soil or rock can be effectively prevented, and the stability of the infrastructure can be maintained. Improve the safety of the working face: The use of mining anchors can strengthen the support of the working face, prevent rock instability and roof collapse, and ensure the safety of miners.

[0035] like Figure 1 As shown, a roof anchor hole entry device includes a PVC tube 6 for placing one or more sections of anchors, both ends of the PVC tube 6 are not sealed, and when in use, the anchor drill bit 3 pushes upward against the lower anchor inside the PVC tube 6, and one side of the tube wall of the PVC tube 6 passes through an opening from top to bottom, and the opening width is smaller than the diameter of the anchor and larger than the diameter of the anchor drill bit 3.

[0036] The roof anchor hole device can solve the problem that the anchor is soft and difficult to be delivered into the anchor hole when the roof anchor is constructed in coal mines. The roof anchor hole device can ensure that the anchor fully fills the anchor hole and exerts the expected consolidation effect. This helps to improve the safety and stability of the mine and ensure the normal progress of mining operations. The anchor hole device is suitable for various types of geological environments and engineering construction scenarios, and can be used in different types of anchor drilling. It has strong applicability and flexibility. By using a notched anchor hole device to push the anchor, the anchor hole speed can be increased, thereby improving the progress of anchor construction. Using an anchor hole device to push the anchor into the anchor hole is an efficient, precise, safe and cost-saving construction method. It can not only improve work efficiency and quality, but also effectively ensure construction safety and stability, and provide a good foundation for long-term use.

[0037] The opening width of the PVC tube 6 is smaller than the diameter of the anchor and larger than the diameter of the anchor drill bit 3. In the process of pushing the anchor to the designated position, the anchor can be prevented from falling through the opening. However, in the recovery process, since the opening width of the PVC tube 6 is larger than the diameter of the anchor drill bit, the PVC tube 6 can be easily taken out from the anchor drill bit 3. Since the anchor drill bit 3 is holding the first anchor 4 and the second anchor 5, the first anchor 4 and the second anchor 5 do not fall in the anchor borehole 2. Therefore, taking out the PVC tube does not affect the fixation and use of the anchor.

[0038] In one embodiment, Figure 2 As shown, the PVC pipe 6 also includes a pushing gasket 7 for pushing the anchor agent. One side of the pushing gasket 7 is provided with a groove connected to the top of the anchor drill bit 3. The shape of the groove is adapted to the shape of the top of the anchor drill bit 3. The other side of the pushing gasket 7 is connected to the anchor agent.

[0039] Preferably, the size of the pushing gasket 7 is smaller than the diameter of the PVC pipe 6 .

[0040] Since the texture of the anchor is relatively soft, the contact area with the anchor can be increased by providing a pushing gasket, thereby preventing the anchor drill bit from directly contacting the anchor and causing deformation of the anchor; and by providing a structure adapted to the top of the anchor drill bit on one side of the pushing gasket, the pushing gasket and the anchor drill bit can be effectively connected, and the anchor can be pushed smoothly when in use. In the case of pushing multiple sections of anchor, the anchor can be pushed to the designated position of the anchor hole more effectively, avoiding deformation and bending of the anchor during the pushing process.

[0041] The size of the pushing gasket is smaller than the diameter of the PVC pipe 6. When in use, after one or more sections of anchoring agent are pushed to the specified position by the anchor drill bit, the restriction on the PVC pipe 6 is released. Since the size of the PVC pipe 6 is larger than the size of the pushing gasket 7 and the size of the anchoring agent, the PVC pipe 6 can easily slide to the position below the anchor drill bit 3 after losing the restriction, which is convenient for the recovery of the PVC pipe 6.

[0042] In one embodiment, the PVC pipe 6 also includes a pushing gasket 7 for pushing the anchor agent. A buckle connected to the top of the anchor drill bit 3 is provided on one side of the pushing gasket 7. The shape of the buckle is adapted to the shape of the top of the anchor drill bit 3. The other side of the pushing gasket 7 is connected to the anchor agent.

[0043] Since the texture of the anchor is relatively soft, the contact area with the anchor can be increased by providing a pushing gasket, thereby preventing the anchor drill bit from directly contacting the anchor and causing deformation of the anchor; and by providing a structure adapted to the top of the anchor drill bit on one side of the pushing gasket, the pushing gasket and the anchor drill bit can be effectively connected, and the anchor can be pushed smoothly when in use. In the case of pushing multiple sections of anchor, the anchor can be pushed to the designated position of the anchor hole more effectively, avoiding deformation and bending of the anchor during the pushing process.

[0044] The size of the pushing gasket is smaller than the diameter of the PVC pipe 6. When in use, after one or more sections of anchoring agent are pushed to the specified position by the anchor drill bit, the restriction on the PVC pipe 6 is released. Since the size of the PVC pipe 6 is larger than the size of the pushing gasket 7 and the size of the anchoring agent, the PVC pipe 6 can easily slide to the position below the anchor drill bit 3 after losing the restriction, which is convenient for the recovery of the PVC pipe 6.

[0045] In one embodiment, Figure 6 As shown, the present invention provides a roof anchor pushing method, comprising:

[0046] S601, after the anchor holes are obtained by drilling anchor holes in the construction roof, one or more sections of anchoring agents are loaded into the roof anchoring agent entry device.

[0047] S602, start the anchor drilling machine and send the anchor injection device loaded with anchor into the anchor hole.

[0048] like Figure 3As shown, the bolt drill bit 3 pushes upward against the second anchor 5 inside the PVC pipe 6, the bolt drill is started, and the PVC pipe 6 loaded with the first anchor 4 and the second anchor 5 is sent into the bolt hole 2. The PVC pipe loaded with anchors is sent into the bolt hole together, which can solve the problem that the anchor is soft and difficult to be sent into the bolt hole when the roof bolt is constructed in the coal mine. The roof anchor hole feeding device can ensure that the anchor fully fills the bolt hole and exerts the expected consolidation effect. This helps to improve the safety and stability of the mine and ensure the normal progress of mining operations.

[0049] S603, after the anchoring agent is delivered to the designated position, the anchoring agent entry device is lowered and recovered.

[0050] like Figure 4 As shown, after the PVC tube 6 loaded with the first anchor 4 and the second anchor 5 is delivered to the specified position of the anchor hole 2, the PVC tube 6 is loosened. Since the diameter of the PVC tube 6 is larger than the size of the first anchor 4 and the second anchor 5, the PVC tube 6 can easily slide to the position below the anchor drill bit 3 after losing the restriction.

[0051] In one embodiment, the method of starting the anchor drilling machine and delivering the anchoring agent injection device loaded with anchoring agent into the anchor hole includes:

[0052] Fix the top of the anchor drill bit with the groove of the push pad of the anchoring agent hole-entering device;

[0053] The anchor drilling machine is started, and the pushing gasket of the anchor hole feeding device pushes the anchor into the anchor hole, and at the same time, the PVC pipe is pushed into the anchor hole.

[0054] Since the texture of the anchor is relatively soft, the contact area with the anchor can be increased by providing a pushing gasket, thereby preventing the anchor drill bit from directly contacting the anchor and causing deformation of the anchor; and by providing a structure adapted to the top of the anchor drill bit on one side of the pushing gasket, the pushing gasket and the anchor drill bit can be effectively connected, and the anchor can be pushed smoothly when in use. In the case of pushing multiple sections of anchor, the anchor can be pushed to the designated position of the anchor hole more effectively, avoiding deformation and bending of the anchor during the pushing process.

[0055] The size of the pushing gasket is smaller than the diameter of the PVC pipe 6. When in use, after one or more sections of anchoring agent are pushed to the specified position by the anchor drill bit, the restriction on the PVC pipe 6 is released. Since the size of the PVC pipe 6 is larger than the size of the pushing gasket 7 and the size of the anchoring agent, the PVC pipe 6 can easily slide to the position below the anchor drill bit 3 after losing the restriction, which is convenient for the recovery of the PVC pipe 6.

[0056] In one embodiment, the method of starting the anchor drilling machine and delivering the anchoring agent injection device loaded with anchoring agent into the anchor hole includes:

[0057] Fix the top of the anchor drill bit with the buckle of the push pad of the anchoring agent hole entry device;

[0058] The anchor drilling machine is started, and the pushing gasket of the anchor hole feeding device pushes the anchor into the anchor hole, and at the same time, the PVC pipe is pushed into the anchor hole.

[0059] Since the texture of the anchor is relatively soft, the contact area with the anchor can be increased by providing a pushing gasket, thereby preventing the anchor drill bit from directly contacting the anchor and causing deformation of the anchor; and by providing a structure adapted to the top of the anchor drill bit on one side of the pushing gasket, the pushing gasket and the anchor drill bit can be effectively connected, and the anchor can be pushed smoothly when in use. In the case of pushing multiple sections of anchor, the anchor can be pushed to the designated position of the anchor hole more effectively, avoiding deformation and bending of the anchor during the pushing process.

[0060] The size of the pushing gasket is smaller than the diameter of the PVC pipe 6. When in use, after one or more sections of anchoring agent are pushed to the specified position by the anchor drill bit, the restriction on the PVC pipe 6 is released. Since the size of the PVC pipe 6 is larger than the size of the pushing gasket 7 and the size of the anchoring agent, the PVC pipe 6 can easily slide to the position below the anchor drill bit 3 after losing the restriction, which is convenient for the recovery of the PVC pipe 6.

[0061] In one embodiment, Figure 5 As shown, after the anchoring agent is delivered to the designated position, the anchoring agent hole-entering device is dropped and recovered, including:

[0062] After the anchoring agent is delivered to the designated position, the PVC pipe is loosened and the PVC pipe is separated from the anchor drill bit through one side of the through opening.

[0063] The opening width of the PVC tube 6 is smaller than the diameter of the anchor and larger than the diameter of the anchor drill bit 3. In the process of pushing the anchor to the designated position, the anchor can be prevented from falling through the opening. However, in the recovery process, since the opening width of the PVC tube 6 is larger than the diameter of the anchor drill bit, the PVC tube 6 can be easily taken out from the anchor drill bit 3. Since the anchor drill bit 3 is holding the first anchor 4 and the second anchor 5, the first anchor 4 and the second anchor 5 do not fall in the anchor borehole 2. Therefore, taking out the PVC tube does not affect the fixation and use of the anchor.

[0064] The above description is only one or more embodiments of this specification and is not intended to limit this specification.
