It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0039] This embodiment provides a device for calculating the amount of anchor grouting. Figure 1 and Figure 2 As shown, it includes an anchor rod 1, a connecting chamber 2, a cover chamber 3, a grouting pipe 4 and a flow measurement component 5;

[0040] The grouting pipe 4 is connected to the connecting chamber 2, and one end of the grouting pipe 4 extends into the connecting chamber 2, and the other end extends out of the connecting chamber 2 for grouting;

[0041] The cover bin 3 is detachably connected to the top of the connecting bin 2. The grouting pipe 4 is connected to the cover bin 3. One end of the grouting pipe 4 extends into the cover bin 3 and is sealed and connected to the anchor rod 1. The other end extends out of the cover bin 3.

[0042] The flow measurement component 5 is connected to one end of the grouting pipe 4 extending into the cover chamber 3 , and the flow measurement component 5 extends out of the cover chamber 3 to display the flow in the grouting pipe 4 .

[0043] When the above anchor grouting quantity calculation device is working, if Figure 1 As shown, the cover chamber 3 is connected to the connecting chamber 2, and the end of the grouting pipe 4 extending into the cover chamber 3 is sealed and connected to the anchor rod 1. The slurry can enter the anchor rod 1 through the grouting pipe 4 and grouting is achieved through the anchor rod 1. At the same time, Figure 2 As shown, the flow measurement assembly 5 measures the flow of the grouting pipe 4 and displays it on the outside of the cover bin 3.

[0044] Therefore, the anchor grouting amount calculation device in this embodiment can measure the grouting amount to ensure accurate grouting. Figure 3 As shown, the cover chamber 3 and the connection chamber 2 in the anchor grouting quantity calculation device provided in this embodiment can be disassembled to facilitate the disassembly and assembly operations of the flow measurement component.

[0045] The interiors of the cover bin 3 and the connecting bin 2 are both hollow, and there are various ways to detachably connect the cover bin 3 and the connecting bin 2, such as snapping the cover bin 3 and the connecting bin 2 together, or connecting the cover bin 3 and the connecting bin 2 through bolts and nuts.

[0046] In an optional embodiment, if Figure 4 As shown, the cover bin 3 and the connecting bin 2 are detachably connected by a first fixing member 6, a second fixing member 7, a rotating rod 8 and a locking member 9, wherein: the first fixing member 6 is fixed to the outer surface of the connecting bin 2, and the rotating rod 8 rotates with the first fixing member 6; the second fixing member 7 is fixed to the outer surface of the cover bin 3 and is arranged opposite to the first fixing member 6 along an extension direction parallel to the anchor rod 1, and a through groove 71 is provided on the second fixing member 7 for the rotating rod 8 to be rotated in so that the rotating rod 8 passes through the second fixing member 7; the locking member 9 is movably connected to the rotating rod 8, and the locking member 9 is used to press on the surface of the second fixing member 7 away from the first fixing member 6 to lock the position of the rotating rod 8 relative to the second fixing member 7.

[0047] When in use, the position of the locking piece 9 can be adjusted so that the locking piece 9 cancels the surface of the second fixing piece 7 away from the first fixing piece 6, and then the rotating rod 8 is rotated so that the rotating rod 8 exits the through slot 71, canceling the penetration of the rotating rod 8 into the second fixing piece 7, and the cover bin 3 can be removed from the connecting bin 2; when it is necessary to lock the position of the cover bin 3 relative to the connecting bin 2, the cover bin 3 can be aligned with the connecting bin 2, and then the rotating rod 8 is rotated so that the rotating rod 8 enters the through slot 71. At this time, the rotating rod 8 penetrates the second fixing piece 7, and then the position of the locking piece 9 is adjusted so that the locking piece 9 presses the surface of the second fixing piece 7 away from the first fixing piece 6, and the position of the cover bin 3 relative to the connecting bin 2 can be locked.

[0048] The above structure can ensure the stable connection between the cover compartment 3 and the connecting compartment 2, and is easy to assemble and disassemble, which is convenient for users to operate.

[0049] In an optional embodiment, in order to enable the locking member 9 to stably press against the surface of the second fixing member 7 facing away from the first fixing member 6 , the locking member 9 is sleeved on the outside of the rotating rod 8 and threadedly engaged with the rotating rod 8 .

[0050] The above arrangement allows the user to adjust the position of the locking member 9 by simply rotating the locking member 9, which is convenient for the user's operation and makes the locking of the locking member 9 more stable.

[0051] Specifically, the rotating rod 8 can be a screw rod, and the locking member 9 can be a nut.

[0052] In addition, a connecting seat may be provided on the first fixing member 6, and the rotating rod 8 is hinged to the connecting seat.

[0053] In an optional embodiment, if Figure 2 As shown, the flow measurement assembly 5 includes a flow meter 51, a display dial 52 and a display compartment 53, wherein:

[0054] The display compartment 53 is connected to the outer surface of the cover compartment 3, and the display compartment 53 is in communication with the cover compartment 3, so that other structures of the flow measurement assembly 5 can extend out of the cover compartment 3;

[0055] The flow meter 51 is installed on the grouting pipe 4 to measure the flow of the slurry in the grouting pipe 4. The display dial 52 is connected to the flow meter 51 to display the flow measured by the flow meter 51. The display dial 52 is located in the display compartment 53 for easy viewing by the user.

[0056] The display dial 52 and the flow meter 51 are existing products, and their principles are existing technologies, so no further explanation is given here.

[0057] In an optional embodiment, if Figure 5 As shown, the display chamber 53 has an opening, and the opening is movably connected to an observation door 54.

[0058] Specifically, the observation door 54 is in the shape of a plate and is pivotally connected to the opening of the display chamber 53. Under the action of the observation door 54, it is convenient to observe the data displayed on the display dial 52, so as to achieve the effect of precise quantity control.

[0059] The material of the observation door 54 can be glass or transparent plastic.

[0060] In an optional embodiment, if Figure 5 and Figure 6 As shown, the end of the grouting pipe 4 close to the anchor rod 1 includes a first connecting pipe 41, and the first connecting pipe 41 has a first trumpet portion 411 with an opening gradually increasing along the flow direction of the slurry; the end of the anchor rod 1 close to the grouting pipe 4 includes a second connecting pipe 11, and the second connecting pipe 11 has a second trumpet portion 111 with an opening gradually decreasing along the flow direction of the slurry, and the end face of the second trumpet portion 111 close to the grouting pipe 4 is provided with a sealing ring 112 for abutting against the first trumpet portion 411 to ensure a sealed connection between the anchor rod 1 and the grouting pipe 4.

[0061] When the connecting chamber 2 and the cover chamber 3 are snap-fitted together, the second trumpet portion 111 can extend into the first trumpet portion 411, and the sealing ring 112 at the top of the second trumpet portion 111 can abut against the inner wall of the first trumpet portion 411, thereby sealing the bottom of the first trumpet portion 411 and the top of the second trumpet portion 111, ensuring that the slurry can be smoothly transferred from the first trumpet portion 411 to the second trumpet portion 111.

[0062] Specifically, the material of the sealing ring 112 may be, but is not limited to, rubber, and the sealing ring 112 may be in a circular shape.

[0063] In an optional embodiment, if Figure 5 As shown, the flow meter 51 is connected to the top end of the first connecting pipe 41 , and the top end of the flow meter 51 is connected to the annular pipe 42 in the grouting pipe 4 .

[0064] In an optional embodiment, a one-way control component 10 for controlling the slurry in the first horn portion 411 to flow unidirectionally into the second horn portion 111 is provided in the first horn portion 411 .

[0065] The one-way control component 10 can make the slurry flow into the second horn portion 111 in one direction, thereby improving the safety performance and effect of grouting.

[0066] In an optional embodiment, if Figure 6As shown, the one-way control component 10 includes a control ball 101, a support member and multiple elastic members 103; one end of each elastic member 103 is connected to the inner surface of the first horn portion 411, and the other end of each elastic member 103 is connected to the support member, and the support member is connected to the control ball 101. The end of the control ball 101 that is away from the support member is used to block the end of the first horn portion 411 that is away from the second horn portion 111 under the elastic force of the elastic member 103.

[0067] During grouting, the grouting pressure can overcome the elastic force of each elastic member 103, pushing the control ball 101 downward, so that the control ball 101 stops blocking the end of the first horn portion 411 away from the second horn portion 111, and the slurry can flow from the first horn portion 411 into the second horn portion 111. When grouting is canceled, under the elastic force of the elastic member 103, the support member gives the control ball 101 an upward thrust, thereby driving the control ball 101 to block the end of the first horn portion 411 away from the second horn portion 111.

[0068] The elastic member 103 may be a tension spring, one end of which is fixedly connected to the inner surface of the first horn portion 411 , and the other end of which is fixedly connected to the support member, which may be fixedly connected to the control ball 101 .

[0069] Specifically, the control ball 101 can be hemispherical in shape, and the end thereof away from the second horn portion 111 is a first plane, and the end of the first horn portion 411 away from the second horn portion 111 has a second plane. The first plane can offset the second plane to achieve blocking of the end of the first horn portion 411 away from the second horn portion 111 by the control ball 101.

[0070] Of course, the control ball 101 may also be spherical, and the blocking effect is achieved by abutting the end of the first horn portion 411 away from the second horn portion 111 with its spherical surface.

[0071] The support member can adopt an integrated structure or a split structure.

[0072] In an optional embodiment, the support member includes a plurality of support plates 102 connected to the control ball 101 , and the plurality of support plates 102 are connected to the plurality of elastic members 103 in a one-to-one correspondence.

[0073] Multiple support plates 102 can be evenly spaced around the axis of the control ball 101. One end of the support plate can be fixedly connected to the control ball 101 by welding, bonding, etc., and the other end can be fixedly connected to the elastic member 103 by hooking, welding, bonding, etc.

[0074] In an optional embodiment, if Figure 1 As shown, a limit plate 011 for limiting the grouting depth of the anchor rod 1 is fixedly connected to the outer surface of the anchor rod 1 .

[0075] Specifically, the limiting plate 011 may be disc-shaped.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
