Description

Technical Field

[0001] The present invention relates to the technical field of anchoring construction. More specifically, the present invention relates to an anchoring agent feeding device and a using method thereof. Background Art

[0002] Bolt support is the main support form for rock headings in coal mines in China. With the development of anchor support operations, it is necessary to first drill holes on a fixed foundation, then place bagged anchoring agents into the bolt holes, and then insert bolts into the bolt holes. The bolts are fixed to the bolt hole walls through the adhesive action of the anchoring agents. The existing operation method for installing anchoring agents is that the operator stands on a lifting platform to reach a height suitable for the roof, and then manually inserts the anchoring agent tube into the bolt hole and blocks the bolt hole by hand to prevent the anchoring agent from falling. However, this method has low efficiency and poor safety. Using a liftable anchoring agent conveying device can avoid the operator from working at heights, but the existing anchoring agent conveying device has the problem of inconveniently controlling the anchoring agent tube at high positions during use. Summary of the Invention

[0003] The object of the present invention is to provide an anchoring agent feeding device and a using method thereof. By adjusting the lengths of the first telescopic rod and the second telescopic rod, the height of the inner tube (anchoring agent tube) can be adjusted. By rotating the second telescopic rod, the bottom of the inner tube can be opened or closed to prevent the anchoring agent from falling. By moving the second connecting member on the guide rod, the second opening can be made to face or not face the first opening. When the second opening does not face the first opening, the anchoring agent can be prevented from falling. When the second opening faces the first opening, the inner tube and the outer tube can be taken out from the side of the bolt. The use is simple and convenient.

[0004] To achieve these objects and other advantages of the present invention, there is provided an anchoring agent feeding device, including:

[0005] An inner tube, which is cylindrical and arranged vertically. A first opening is arranged vertically on the inner tube, and the first opening can allow a bolt to pass through;

[0006] An outer tube, which is cylindrical and arranged vertically, and is sleeved outside the inner tube. The outer tube and the inner tube are coaxially arranged. The bottom end of the inner tube extends out of the bottom end of the outer tube. A first connecting member is arranged on the outer tube, and a second opening is arranged vertically;

[0007] A connecting rod, which is arranged horizontally. One end of the connecting rod is fixedly connected to the side wall of the bottom end of the inner tube;

[0008] A first telescopic rod, which is arranged vertically. The top of the first telescopic rod is connected to the other end of the connecting rod;

[0009] A second telescopic rod, which is arranged vertically. The top of the second telescopic rod is rotatably connected to the first connecting member;

[0010] The guide rod is arc-shaped, and its center of circle is located on the axis of the inner tube. The guide rod is fixed at the bottom end of the first telescopic rod. A second connecting piece is sleeved on the guide rod, and the second connecting piece can move along the circumferential direction of the guide rod. The bottom of the second telescopic rod is rotatably connected to the second connecting piece. When the second connecting piece moves on the guide rod, the second connecting piece can drive the second telescopic rod to move, and further drive the outer tube to rotate along its circumferential direction. When the second connecting piece drives the outer tube to rotate along its circumferential direction, the second opening can be opposite to or not opposite to the first opening.

[0011] The cover is fixed on the second telescopic rod. When the second telescopic rod rotates, the cover can seal or open the bottom of the inner tube. When the cover opens the bottom of the inner tube, the cover is not opposite to the bottoms of both the inner tube and the outer tube.

[0012] Preferably, in the anchoring agent feeding device, the inner diameter of the outer tube is equal to the outer diameter of the inner tube. The cover is circular, and its outer diameter is greater than or equal to the outer diameter of the inner tube. A third connecting piece is arranged on the outer edge of the cover, and the third connecting piece is fixed on the second telescopic rod. When the cover seals the bottom of the inner tube, the center of the cover is located on the axis of the inner tube.

[0013] Preferably, in the anchoring agent feeding device, a limiting block is arranged at one end of the guide rod, and the second connecting piece cannot pass through the limiting block. The other end of the guide rod is fixed on the side wall of the bottom end of the first telescopic rod. When the second connecting piece moves on the guide rod from one end to the other end, the second opening changes from not being opposite to the first opening to being opposite to the first opening.

[0014] Preferably, in the anchoring agent feeding device, a first guiding block is arranged along the circumferential direction on the outer wall of the inner tube. The cross-section of each part of the first guiding block is T-shaped. The middle end of the first guiding block is fixed on the side wall of the inner tube and is in contact with the side wall of the inner tube. The first guiding block is not opposite to the first opening. A first guiding groove matching with the first guiding block is arranged along the circumferential direction on the inner wall of the outer tube, and the first guiding block is located in the first guiding groove.

[0015] Preferably, in the anchoring agent feeding device, the top end of the inner tube extends out of the top end of the outer tube, and a pair of abutting blocks are arranged thereon.

[0016] Preferably, in the anchoring agent feeding device, the part of the second telescopic rod below the cover is composed of multiple sleeves arranged in sequence from top to bottom. The top of the sleeve at the top is fixedly connected to the cover, and the bottom of the sleeve at the bottom is rotatably connected to the second connecting piece. In two adjacent sleeves, a pair of second guiding grooves are arranged on the inner side wall of the sleeve at the upper part. The second guiding grooves are arranged vertically. The top end of the sleeve at the lower part passes through the bottom of the sleeve at the upper part, and a pair of second guiding blocks are arranged on its side wall. The pair of second guiding blocks are respectively located in the pair of second guiding grooves, so that two adjacent sleeves can only move relatively up and down.

[0017] Preferably, in the anchoring agent feeding device, each sleeve is a hollow cylinder.

[0018] Preferably, in the anchoring agent feeding device, the outer diameter of the cover is equal to the outer diameter of the inner tube.

[0019] The using method of the anchoring agent feeding device includes the following steps:

[0020] Step 1: Make the second opening not opposite to the first opening, and the cover seal the bottom of the inner tube, and then put the anchoring agent into the inner tube in sequence.

[0021] Step 2: Adjust the lengths of the first telescopic rod and the second telescopic rod to move the top end of the inner tube to the position of the bolt hole and align it with the bolt hole. Then move the bolt to the bottom of the cover, and then rotate the second telescopic rod to open the bottom of the inner tube. At the same time, insert the bolt from the bottom of the inner tube, and then push the anchoring agent into the bolt hole through the bolt until it reaches the bottom of the hole.

[0022] Step 3: Make the second opening opposite to the first opening, and take out the inner tube and the outer tube from the side of the bolt.

[0023] The present invention has at least the following beneficial effects:

[0024] By adjusting the lengths of the first telescopic rod and the second telescopic rod, the height of the inner tube (anchoring agent tube) can be adjusted. By rotating the second telescopic rod, the bottom of the inner tube can be opened or closed to prevent the anchoring agent from falling. By moving the second connecting piece on the guiding rod, the second opening can be made opposite or not opposite to the first opening. When the second opening is not opposite to the first opening, the anchoring agent can be prevented from falling. When the second opening is opposite to the first opening, the inner tube and the outer tube can be taken out from the side of the bolt. The use is simple and convenient, and no high-altitude operation is required.

[0025] In the present invention, the part of the second telescopic rod below the cover is composed of multiple sleeves arranged in sequence from top to bottom. When adjusting the height of the inner tube, only the length of the first telescopic rod needs to be adjusted, and the second telescopic rod can expand and contract along with the first telescopic rod, so the efficiency is higher.

[0036] The following further describes the present invention in detail with reference to the drawings, so that those skilled in the art can implement it according to the description in the specification.

[0037] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0038] As Figures 1 to 9 shown, the present invention provides an anchoring agent feeding device, including:

[0039] Inner tube 1, which is cylindrical in shape and arranged along the vertical direction. A first opening 101 is arranged on the inner tube 1 along the vertical direction. The first opening 101 can allow the anchor rod 8 to pass through, that is, the inner tube 1 can be taken out from the side of the anchor rod.

[0040] Outer tube 2, which is cylindrical in shape and arranged along the vertical direction, and is sleeved outside the inner tube 1. The outer tube 2 and the inner tube 1 are coaxially arranged. The bottom end of the inner tube 1 extends out of the bottom end of the outer tube 2 to arrange the connecting rod 3. A first connecting piece 201 is arranged on the outer tube 2, and a second opening 202 is arranged along the vertical direction. The widths of the first opening 101 and the second opening 202 are smaller than the diameter of the inner tube 1.

[0041] Connecting rod 3, which is horizontally arranged. One end of the connecting rod 3 is fixedly connected to the side wall of the bottom end of the inner tube 1.

[0042] First telescopic rod 4, which is vertically arranged. The top of the first telescopic rod 4 is connected to the other end of the connecting rod 3. The first telescopic rod 4 is a telescopic rod that does not need to rotate during the telescopic process, that is, each section of the tube body of the first telescopic rod 4 only axially stretches and does not rotate during telescoping.

[0043] Second telescopic rod 5, which is vertically arranged. The top of the second telescopic rod 5 is rotatably connected to the first connecting piece 201.

[0044] The guiding rod 6, which is arc-shaped and has its center of circle located on the axis of the inner tube 1, is fixed to the bottom end of the first telescopic rod 4. A second connecting member 601 is sleeved on the guiding rod 6. The second connecting member 601 can move along the circumferential direction of the guiding rod 6. The bottom of the second telescopic rod 5 is rotatably connected to the second connecting member 601, so that the second telescopic rod 5 can rotate relative to the first connecting member 201 and the second connecting member 601 to open or close the bottom of the inner tube 1. When the second connecting member 601 moves on the guiding rod 6, the second connecting member 601 can drive the second telescopic rod 5 to move, and further drive the first connecting member 201 and the outer tube 2 connected to the first connecting member 201 to rotate along the circumferential direction of the outer tube 2. When the second connecting member 601 drives the outer tube 2 to rotate along its circumferential direction, the second opening 202 can be opposite or not opposite to the first opening 101.

[0045] The sealing cover 7, which is fixed to the second telescopic rod 5. When the second telescopic rod 5 rotates, the sealing cover 7 can seal the bottom of the inner tube 1 (as shown in Figure 3 ) or open the bottom of the inner tube 1 (as shown in Figure 4 ). When the sealing cover 7 opens the bottom of the inner tube 1, the sealing cover 7 is not opposite to the bottoms of both the inner tube 1 and the outer tube 2 so as not to interfere with the insertion of the anchor rod into the inner tube 1. As shown in Figure 3 and Figure 4 , in order to open the sealing cover 7 at the bottom of the inner tube 1, the second telescopic rod 5 can be rotated by 180 degrees, and then the sealing cover 7 can be rotated by 180 degrees. Figure 3 In Figure 6 and 7 , since the second connecting member 601 is below the third connecting member 701, when looking at the device from top to bottom, the second connecting member 601 is blocked by the third connecting member 701, so the second connecting member 601 is represented by a dotted line. After the sealing cover 7 rotates by 180 degrees, the part of the second connecting member 601 that is not blocked by the third connecting member 701 is represented by a solid line, and the part blocked by the third connecting member 701 is represented by a dotted line. As shown in Figure 8 and 9 , in the two figures, the first connecting member 201 is represented by a solid-line square, the second connecting member 601 is represented by a dotted-line square, the second telescopic rod 5 is represented by a dotted-line circle, and the second connecting member 601 and the second telescopic rod 5 are located below the first connecting member 201. The structures of the second connecting member 601 and the second telescopic rod 5 are as shown in Figure 8 and 9 .

[0046] When the anchoring agent feeding device provided by this solution is in use, during use, move the second connecting piece 601 on the guiding rod 6 until the second opening 202 is not opposite to the first opening 101, and rotate the first telescopic rod 4 to make the cover 7 seal the bottom of the inner tube 1. Then, put the anchoring agent into the inner tube 1 in sequence; adjust the lengths of the first telescopic rod 4 and the second telescopic rod 5 to move the top end of the inner tube 1 to the position of the bolt hole, and align it with the bolt hole. Then, move the bolt to the bottom of the cover 7 and close to the bottom of the cover 7. Next, rotate the second telescopic rod 5 to make the cover 7 open the bottom of the inner tube 1. At the same time, insert the bolt into the inner tube 1 from the bottom, and then push the anchoring agent into the bolt hole through the bolt until it reaches the bottom of the hole; move the second connecting piece 601 on the guiding rod 6 until the second opening 202 is opposite to the first opening 101, and take out the inner tube 1 and the outer tube 2 from the side of the bolt.

[0047] Specifically, the inner diameter of the outer tube 2 is equal to the outer diameter of the inner tube 1. As Figure 3 and Figure 4 shown, the cover 7 is circular, and its outer diameter is greater than or equal to the outer diameter of the inner tube 1. A third connecting piece 701 is provided on the outer edge of the cover 7, and the third connecting piece 701 is fixed on the second telescopic rod 5. When the cover 7 seals the bottom of the inner tube 1, the center of the cover 7 is located on the axis of the inner tube 1. When the second telescopic rod 5 rotates, it drives the third connecting piece 701 to rotate, and further drives the cover 7 connected to the third connecting piece 701 to rotate.

[0048] Specifically, as Figure 8 and Figure 9 shown, a limiting block 602 is provided at one end of the guiding rod 6, and the second connecting piece 601 cannot pass through the limiting block 602. The other end of the guiding rod 6 is fixed on the side wall of the bottom end of the first telescopic rod 4. As Figure 6 and Figure 7 shown, when the second connecting piece 601 moves on the guiding rod 6 from one end to the other end, the second opening 202 changes from not being opposite to the first opening 101 to being opposite to the first opening 101.

[0049] Specifically, a first guiding block is provided on the outer wall of the inner tube 1 along its circumferential direction. The cross-section of each part of the first guiding block is T-shaped. The middle end of the first guiding block is fixed on the side wall of the inner tube 1 and is in contact with the side wall of the inner tube 1. The first guiding block is not opposite to the first opening 101. A first guiding groove matching the first guiding block is provided on the inner wall of the outer tube 2 along its circumferential direction. The cross-section of each part of the first guiding groove is T-shaped. The first guiding block is located in the first guiding groove. By providing the T-shaped first guiding block and the T-shaped first guiding groove, the first guiding block will not come out of the first guiding groove, and the outer tube 2 can only rotate relative to the inner tube 1 along the circumferential direction.

[0050] Specifically, the top end of the inner tube 1 extends out of the top end of the outer tube 2, and a pair of abutting blocks 102 are arranged thereon. During the advancement of the anchoring agent, it abuts against the outer wall of the bolt hole through the pair of abutting blocks, which can prevent the inner tube 1 and the outer tube 2 from advancing together with the bolt.

[0051] Specifically, the part of the second telescopic rod 5 below the cover 7 is composed of multiple sections of sleeves arranged from top to bottom in sequence. The top of the sleeve at the topmost part is fixedly connected to the cover 7, and the bottom of the sleeve at the bottommost part is rotatably connected to the second connecting member 601. Among adjacent two sections of sleeves, a pair of second guiding grooves are arranged on the inner side wall of the sleeve at the upper part, and the second guiding grooves are arranged vertically. The top end of the sleeve at the lower part passes through the bottom of the sleeve at the upper part above it, and a pair of second guiding blocks 501 are arranged on its side wall. The pair of second guiding blocks 501 are respectively located in the pair of second guiding grooves, so that adjacent two sections of sleeves can only move relatively up and down. By making the part of the second telescopic rod 5 below the cover 7 composed of multiple sections of sleeves arranged from top to bottom in sequence, when adjusting the heights of the inner tube 1 and the outer tube 2, only the length of the first telescopic rod 4 needs to be adjusted, and the second telescopic rod 5 can extend and contract along with the first telescopic rod 4, so the efficiency is higher.

[0052] Specifically, each section of sleeve is a hollow cylindrical shape.

[0053] Specifically, the outer diameter of the cover 7 is equal to the outer diameter of the inner tube 1.

[0054] The using method of the anchoring agent feeding device includes the following steps:

[0055] Step 1: Move the second connecting member 601 on the guiding rod 6 until the second opening 202 is not opposite to the first opening 101, then rotate the second telescopic rod 5 to make the cover 7 seal the bottom of the inner tube 1, and then sequentially put the anchoring agent into the inner tube 1;

[0056] Step 2: Adjust the lengths of the first telescopic rod 4 and the second telescopic rod 5 to move the top end of the inner tube 1 to the bolt hole and align it with the bolt hole. Then move the bolt to the bottom of the cover 7 and close to the cover 7. Then rotate the second telescopic rod 5 to open the bottom of the inner tube 1 by the cover 7. At the same time, insert the bolt into the inner tube 1 from the bottom, and then push the anchoring agent into the bolt hole until the bottom of the hole through the bolt;

[0057] Step 3: Move the second connecting member 601 on the guiding rod 6 until the second opening 202 is opposite to the first opening 101, and take out the inner tube 1 and the outer tube 2 from the side of the bolt.

[0058] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made.
