Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and in particular to a novel tunnel anchor grouting device. Background Technology

[0002] As an important part of tunnel construction, tunnel anchor bolt construction is often insufficient to resist the huge deformation of the surrounding rock by shotcrete alone, and cannot effectively guarantee the reliability of the support. In this case, the anchoring effect of anchor bolts is needed to achieve effective support.

[0003] In tunnel anchor bolt construction, anchor bolt grouting is an extremely important process. At present, many grouting equipment uses electricity to provide the power for mixing and grouting. However, there are many cases of water seepage and accumulation in tunnels. For safety reasons, the use of electricity should be reduced.

[0004] In addition, the existing equipment is heavy and difficult to transport and move, which slows down the construction speed and affects the overall construction progress of the tunnel. Currently, air pressure grouting is also used in the construction of tunnel anchor bolts, but the equipment is simple and lacks a grout mixing device. During the construction process, the grout may settle, affecting the grouting effect. Moreover, the existing equipment support structure is a fixed steel scaffold, which does not take into account the construction safety caused by uneven ground, thus affecting the construction. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that the large weight of the equipment makes it difficult to transport and move, which slows down the construction speed and affects the overall construction progress of the tunnel.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a novel tunnel anchor bolt grouting device, comprising:

[0007] The grouting tank body has a first partition plate on its inner wall, a second partition plate below the first partition plate, and a third partition plate below the second partition plate. The first partition plate and the top surface of the inner cavity of the grouting tank body form a piston chamber, and a driving mechanism is provided in the piston chamber.

[0008] The driving mechanism includes a piston sleeve, the right side of which is connected to the inner wall of the grouting tank body. A piston is installed inside the grouting tank body, and a piston rod is installed on the left side of the piston. One end of the piston rod passes through the piston sleeve and is connected to a connecting rod via a rotating shaft. A fixing screw is installed on the lower side of the connecting rod, and a wheel is connected to the fixing screw. A wheel shaft is installed on the lower surface of the wheel, and a driving gear is installed on the outer wall of the wheel shaft. The driving gear meshes with a driven gear, and a stirring rod is installed at the axis of the driven gear.

[0009] Preferably, a gear chamber is provided between the first partition plate and the second partition plate, with the driving gear and the driven gear located in the gear chamber.

[0010] Preferably, a stirring chamber is provided between the second partition plate and the third partition plate, and a stirring rod is located in the stirring chamber.

[0011] Preferably, a piston pneumatic branch pipe is provided on the outer wall of the grouting tank body, and one end of the piston pneumatic branch pipe passes through the outer wall of the grouting tank body and is connected to the piston sleeve. The other end of the piston pneumatic branch pipe is connected to an air inlet branch pipe, and a valve is installed on the air inlet branch pipe.

[0012] Preferably, the third partition plate forms a storage chamber with the bottom surface of the inner cavity of the grouting tank body, and one end of the air inlet branch pipe passes through the outer wall of the grouting tank body and is connected to the storage chamber.

[0013] Preferably, a grouting valve is provided on the lower surface of the grouting tank body at its axis, and the grouting valve is connected to the bottom surface of the grouting tank body. Triangular supports are provided around the grouting valve on the bottom surface of the grouting tank body.

[0014] Preferably, the third partition plate is provided with a grout leakage hole, and the main body of the grouting tank is provided with a manual valve on one side of the third partition plate, and the manual valve is used to control the opening and closing of the grout leakage hole.

[0015] Preferably, the upper surface of the grouting tank body is symmetrically provided with a water inlet and a feed inlet about its axis, and both the water inlet and the feed inlet pass through the first partition plate and the second partition plate and are connected to the mixing chamber.

[0016] Preferably, the outer wall of the grouting tank body is provided with handles symmetrically about its axis.

[0017] Preferably, the piston sleeve has a vacuum jacket, and a piston partition is provided on one side of the piston in the inner cavity of the piston sleeve. A butterfly valve is installed on the piston partition. An upper air inlet pipe and a lower inclined pipe are symmetrically arranged on the right side of the piston partition about the bearing seat of the butterfly valve. The upper air inlet pipe passes through the jacket and communicates with the inner cavity of the piston sleeve. A pressure relief valve communicating with the jacket is installed on the outer wall of the piston sleeve.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] 1. This invention uses changes in air pressure to cause a piston to reciprocate. The piston drives a connecting rod via a piston rod, which in turn drives a wheel via a fixing screw. The wheel then drives a wheel shaft to rotate, which in turn drives a drive gear. The drive gear then drives a meshing driven gear, which in turn drives a driven gear. This allows the driven gear to synchronously drive a mixing rod, which then rapidly agitates the concrete materials and water. This transmission method eliminates the need for a motor, reducing electricity consumption during construction and preventing electrical leakage hazards in seepage tunnels. This significantly improves the safety of the construction site.

[0020] 2. The present invention can control the air intake of the air intake branch pipe through the valve, so that the air intake branch pipe can regulate the air pressure in the storage chamber, and by controlling the air pressure, the concrete mixture in the storage chamber can be quickly injected into the tunnel anchor bolt.

[0021] 3. The present invention can easily adjust the grouting tank body to a horizontal state by means of the triangular bracket set on the lower surface of the grouting tank body, so that the grouting tank body can work stably in the tunnel.

[0022] 4. The present invention allows for easy movement of the grouting tank body via a handle. Thus, when the new tunnel anchor grouting equipment needs to be moved, only two people are needed to hold the handle to move the new tunnel anchor grouting equipment conveniently.

[0032] The present invention will now be described in further detail.

[0033] Example 1:

[0034] See Figure 1 - Figure 5 As shown,

[0035] A novel tunnel anchor grouting device includes:

[0036] The grouting tank body 15 has a first partition plate 10 on its inner wall, a second partition plate 12 located below the first partition plate 10 on its inner wall, and a third partition plate 13 located below the second partition plate 12 on its inner wall. The first partition plate 10 and the top surface of the inner cavity of the grouting tank body 15 form a piston chamber, and a driving mechanism 11 is provided in the piston chamber.

[0037] The drive mechanism 11 includes a piston sleeve 1101. The right side of the piston sleeve 1101 is connected to the inner wall of the grouting tank body 15. A piston 1102 is provided inside the grouting tank body 15. A piston rod 1103 is provided on the left side of the piston 1102. One end of the piston rod 1103 passes through the piston sleeve 1101 and is connected to a connecting rod 1104 via a rotating shaft. A fixing screw 1105 is provided on the lower side of the connecting rod 1104. The fixing screw 1105 is connected to a wheel 1106. A wheel shaft 1107 is provided on the lower surface of the wheel 1106. A drive gear 1108 is provided on the outer wall of the wheel shaft 1107. The drive gear 1108 is meshed with a driven gear 1109. A stirring rod 11010 is provided at the axis of the driven gear 1109.

[0038] The above structure allows for the following: When tunnel anchor bolt grouting is required, the tunnel anchor bolt grouting equipment is moved to the grouting position. Concrete raw materials and water are then injected into the mixing chamber through the feed hole 1 and water inlet 2, respectively. Next, the air inlet branch pipe 7 is vented, allowing air to be introduced into the piston pneumatic branch pipe 5. The gas in the piston pneumatic branch pipe 5 then enters the piston sleeve 1101. Driven by the gas, the piston 1102 moves within the piston sleeve 1101. The piston 1102 then pushes the piston rod 1103, which in turn drives the connecting rod 1104 via a rotating shaft. The connecting rod 1104 then... 104 drives the wheel 1106 through the fixing screw 1105, then the wheel 1106 drives the wheel shaft 1107 to rotate, then the wheel shaft 1107 drives the drive gear 1108, then the drive gear 1108 drives the meshing driven gear 1109, so the driven gear 1109 can drive the mixing rod 11010 synchronously, and then the mixing rod 11010 can quickly stir the concrete raw materials and water. The above transmission does not require the use of a motor to provide power, which can reduce the electricity consumption during construction, thereby avoiding the risk of electric leakage in the seepage tunnel, and greatly improving the safety of the construction site.

[0039] A gear chamber is provided between the first partition plate 10 and the second partition plate 12, and the driving gear 1108 and the driven gear 1109 are located in the gear chamber.

[0040] The above structure allows for the following: when it is necessary to mix concrete raw materials and water in the mixing chamber, the piston 1102 is first started by the piston air pressure branch pipe 5. Then, the piston 1102 drives the piston rod 1103, which in turn drives the connecting rod 1104. The connecting rod 1104 then drives the wheel 1106, which in turn drives the drive gear 1108 through the wheel shaft 1107. The drive gear 1108 then drives the driven gear 1109, which in turn drives the mixing rod 11010 to quickly stir the concrete raw materials and water, thus ensuring that the concrete raw materials and water are fully mixed.

[0041] A stirring chamber is provided between the second partition plate 12 and the third partition plate 13, and the stirring rod 11010 is located in the stirring chamber.

[0042] The above structure allows for the thorough mixing of concrete raw materials and water within the mixing chamber by the stirring rod 11010, resulting in a more complete mixing of the concrete raw materials and water.

[0043] Preferably, a piston pneumatic branch pipe 5 is provided on the outer wall of the grouting tank body 15, and one end of the piston pneumatic branch pipe 5 passes through the outer wall of the grouting tank body 15 and is connected to the piston sleeve 1101. The other end of the piston pneumatic branch pipe 5 is connected to an air inlet branch pipe 7, and a valve 6 is installed on the air inlet branch pipe 7.

[0044] The above structure allows for the following: when it is necessary to mix concrete raw materials and water in the mixing chamber, gas is pumped into the piston pneumatic branch pipe 5 via an air pump. The gas in the piston pneumatic branch pipe 5 is then transported into the piston sleeve 1101. By controlling the gas, the reciprocating motion of the piston 1102 can be controlled. The reciprocating power provided by the piston 1102 can then drive the connecting rod 1104. The connecting rod 1104 then drives the wheel shaft 1107 via the fixing screw 1105. The wheel shaft 1107 then drives the drive gear 1108. The drive gear 1108 then drives the driven gear 1109. Thus, the driven gear 1109 can drive the mixing rod 11010 to rotate. At the same time, the air intake branch pipe 7 can be controlled by the valve 6 to allow air to enter. The air intake branch pipe 7 can regulate the air pressure in the storage chamber. By controlling the air pressure, the concrete mixture in the storage chamber can be quickly injected into the tunnel anchor bolt.

[0045] The third partition plate 13 and the inner cavity bottom surface of the grouting tank body 15 form a storage chamber, and one end of the air inlet branch pipe 7 passes through the outer wall of the grouting tank body 15 and is connected to the storage chamber.

[0046] The above structure allows for the regulation of air pressure within the storage chamber via the air inlet branch pipe 7, enabling the rapid injection of concrete mixture into the grouting pipe.

[0047] A grouting valve 9 is provided on the lower surface of the grouting tank body 15 at its axis, and the grouting valve 9 is connected to the bottom surface of the grouting tank body 15. A triangular bracket 8 is provided around the grouting valve 9 on the bottom surface of the grouting tank body 15.

[0048] The above structure allows the grouting tank body 15 to be easily adjusted to a horizontal position by the triangular bracket 8 set on the lower surface of the grouting tank body 15, thus enabling the grouting tank body 15 to work stably in the tunnel.

[0049] The third partition plate 13 is provided with a grout leakage hole 14, and the grouting tank body 15 is provided with a manual valve 4 on one side of the third partition plate 13, and the manual valve 4 is used to control the opening and closing of the grout leakage hole 14.

[0050] The above structure allows the manual valve 4 to control the concrete in the mixing chamber to enter the storage chamber through the control grout leakage hole 14.

[0051] The upper surface of the grouting tank body 15 is symmetrically provided with a water inlet 2 and a feed inlet 1 about its axis, and both the water inlet 2 and the feed inlet 1 pass through the first partition plate 10 and the second partition plate 12 and are connected to the mixing chamber.

[0052] The above structure allows for the following: when grouting of tunnel anchor bolts is required, the prepared concrete raw materials are fed into the mixing chamber through the feed hole 1, and water is fed into the mixing chamber through the water inlet 2, so that the water and concrete raw materials are fully mixed in the mixing chamber.

[0053] The outer wall of the grouting tank body 15 is symmetrically provided with handles 3 about its axis.

[0054] The above structure allows for convenient movement of the grouting tank body 15 via the handle 3.

[0055] Example 2:

[0056] See Figure 6 - Figure 8 As shown,

[0057] The piston sleeve 1101 is provided with a vacuum jacket 11016. A piston partition 11012 is provided in the inner cavity of the piston sleeve 1101 on one side of the piston 1102. A butterfly valve 11014 is installed on the piston partition 11012. An upper air inlet pipe 11013 and a lower inclined pipe 11015 are symmetrically arranged on the right side of the piston partition 11012 about the bearing of the butterfly valve 11014. The upper air inlet pipe 11013 passes through the jacket 11016 and communicates with the inner cavity of the piston sleeve 1101. A pressure relief valve 11011 that communicates with the jacket 11016 is installed on the outer wall of the piston sleeve 1101.

[0058] The above structure results in the following: When the stirring rod 11010 is driven, air is pumped into the inner cavity of the piston sleeve 1101. The gas in the piston sleeve 1101 first passes through the piston partition 11012 via the 45° downward inclined pipe 11015, pushing the piston 1102. During its movement, the piston 1102 compresses the gas in front of it. The gas compressed by the piston 1102 then enters the upper air intake pipe 11013. The gas in the upper air intake pipe 11013 is then guided to the right side of the piston partition 11012 through the intake pipe 11013. The gas discharged in this way can push the butterfly valve 11014 downward to open it. The rotated butterfly valve 11014 can then open the upper air intake pipe 11012. The right end of the air inlet of the air pipe 11013 is opened, and at the same time, the butterfly valve 11014 closes the air inlet of the downward inclined pipe 11015 as it rotates downward. This allows gas to enter after the right end of the upper air inlet pipe 11013 is opened. Then, the gas enters the left side of the piston partition 11012 from the left end of the upper air inlet pipe 11013. The gas that enters pushes the piston 1102 to the right. Thus, the piston 1102 can form a reciprocating motion under the action of the air intake of the upper air inlet pipe 11013 and the downward inclined pipe 11015. The reciprocating piston 1102 can continuously provide power to the stirring rod 11010. The pressure relief valve 11011 is used to keep the air pressure in the piston sleeve 1101 stable.

[0059] Working principle: The tunnel anchor grouting equipment is moved to the grouting position. Concrete raw materials and water are then injected into the mixing chamber through the feed hole 1 and water inlet 2, respectively. Next, air is introduced into the air inlet branch pipe 7, and then a gas pump delivers gas into the air inlet branch pipe 7. Simultaneously, the air inlet branch pipe 7 guides the gas into the piston pneumatic branch pipe 5. The gas in the piston pneumatic branch pipe 5 then enters the piston sleeve 1101. Driven by the gas, the piston 1102 moves within the piston sleeve 1101. The piston 1102 then pushes the piston rod 1103, which in turn drives the connecting rod 1104 via a rotating shaft. The connecting rod 1104 then drives the wheel 1106 via a fixing screw 1105. The wheel 1106 then drives the wheel shaft 11. Rotating 07, the circular shaft 1107 drives the drive gear 1108, which in turn drives the meshing driven gear 1109. This drives the driven gear 1109 synchronously, causing the stirring rod 11010 to rapidly agitate the concrete raw materials and water. When the mixed concrete needs to be delivered into the tunnel anchor bolt, the grouting valve 9 is opened, allowing the concrete to be delivered into the tunnel anchor bolt. Simultaneously, the air intake branch pipe 7 is controlled by valve 6 to regulate the air pressure in the storage chamber. By controlling the air pressure, the concrete mixture in the storage chamber can be quickly injected into the tunnel anchor bolt. This is the construction principle of this new type of tunnel anchor bolt grouting equipment.
