[0002] In the process of tunnel support construction, an anchor trolley is usually required to carry out anchor driving operations. In addition, for different rock masses, resin anchors are required to ensure the support effect. During the construction process of resin anchors, it is necessary to pre-inject a paste-like fluid resin agent into the anchor hole. Since the resin agent has a certain viscosity, a special resin agent injection equipment is required during the injection process of the resin agent into the anchor hole. During specific use, the resin agent injection equipment needs to be frequently docked or disassembled with the injection pipe. The entire resin agent injection operation process is relatively cumbersome and the work efficiency is low. Utility Model Content

[0025] Embodiment 1:

[0026] See Figures 1-4 , the resin agent adding valve of the bolt drill jumbo, including bottom plate 2, a valve body mounting plate 4 is fixedly arranged on one side of the top of the bottom plate 2, a valve body 10 is fixedly mounted on the back of the valve body mounting plate 4, a through stepped through-hole 26 is machined at the center of the valve body 10, and the conical inlet 7 of the stepped through-hole 26 is arranged at the upper part of the valve body mounting plate 4; a valve plate shaft 25 is rotatably mounted on the valve body 10, and a flipping valve plate 8 is mounted inside the valve body 10 on the valve plate shaft 25; the flipping valve plate 8 is in limit fit with the stepped through-hole 26, so that the flipping valve plate 8 can only rotate and open towards the outlet direction of the stepped through-hole 26, and is limited and closed in the reverse direction; a connecting pipe 15 is arranged at the end of the valve body 10; an air supply pipe 20 is communicated with the valve body 10 through a first elbow 17, and a water supply pipe 22 is communicated with the valve body 10 through a second elbow 21; both the first elbow 17 and the second elbow 21 are communicated with the stepped through-hole 26 and are located at the part behind the flipping valve plate 8. The adding valve of the present utility model is carried on the bolt drill jumbo, and through the automatic flipping of the flipping valve plate, the automatic locking of the valve body inlet can be realized, and then a certain amount of resin agent is pushed by high-pressure air and injected into the anchor hole, so as to achieve the purpose of resin agent filling.

[0027] Further, during installation, the bottom plate 2 is fixed on the mounting base 1 of the drill jumbo body through a plurality of first bolt assemblies 3. Through the above-mentioned first bolt assemblies 3, the reliable fixation and installation of the base 2 can be realized, thereby ensuring the reliability of its fixed installation.

[0028] Further, stiffening plates 18 are symmetrically fixed between the back of the valve body mounting plate 4 and the bottom plate 2. Through the above-mentioned stiffening plates 18, the fixed reliability between the valve body mounting plate 4 and the bottom plate 2 is enhanced.

[0029] Further, the valve body 10 is fixed on the outer wall of the back of the valve body mounting plate 4 through a valve body seat plate 11 and a plurality of second bolt assemblies 6. Through the above-mentioned second bolt assemblies 6, the reliable fixed installation of the valve body 10 can be realized.

[0030] Furthermore, the outer wall of the connector pipe 15 is provided with a plurality of grooves 23. When in use, the connector pipe 15 is used to connect to a hose, which is used to transport the resin agent to the anchor hole. The grooves 23 enhance the connection strength and reliability between the hose and the connector pipe 15.

[0031] Furthermore, a flap counterweight mechanism is mounted on the valve plate shaft 25 to automatically flip and close the valve plate 8. The flap counterweight mechanism includes a counterweight rod 12, one end of which is secured to the end of the valve plate shaft 25 via a first locking nut 16 and a second locking nut 24. The counterweight rod 12 is arranged perpendicular to the valve plate shaft 25. A limit handle 14 is provided at the end of the counterweight rod 12. The counterweight rod 12 is a threaded rod with an adjusting nut 13 threadedly mounted thereon. This flap counterweight mechanism ensures that the valve plate 8 can automatically flip and close the stepped through hole 26. Among them, when it is necessary to inject resin agent, it is only necessary to automatically push open the flip valve plate 8, and then inject the agent into the interior of the valve body. When the outlet pipe of the resin agent injection equipment is pulled out, the flip valve plate 8 will automatically flip under the action of the counterweight rod 12, and then the flip valve plate 8 will block the stepped through hole 26 to prevent the gas from being discharged from the inlet during subsequent inflation, thereby ensuring that the resin agent inside the valve body is pushed to the delivery hose by high-pressure gas.

[0032] Furthermore, the air supply pipe 20 is synchronously connected to a branch pipe 19, which is connected to a pressure gauge 5. The pressure gauge 5 is fixed to the valve body mounting plate 4, and the dial of the pressure gauge 5 is located on the front of the valve body mounting plate 4. The branch pipe 19 and the pressure gauge 5 are used in conjunction with each other to monitor the air supply pressure, thereby ensuring the best resin agent pushing effect.

[0033] Example 2:

[0034] The method for using the agent adding valve of the anchor trolley comprises the following steps:

[0035] Step 1, installation of the reagent filling valve:

[0036] The reagent filling valve is fixedly installed on the anchor trolley;

[0037] Step 2: Connect the pipes of the reagent filling valve:

[0038] Connect the air supply pipe 20 and the water supply pipe 22 to the valve body 10 respectively, and connect the branch pipe 19 to the pressure gauge 5;

[0039] Step 3, hose connection:

[0040] The hose for delivering the resin agent is fixedly connected to the joint pipe 15, and the other end of the hose is connected to the grouting pipe, which is used to extend into the anchor hole;

[0041] Step 4: Lubricate the hose with water:

[0042] The flip valve plate 8 is initially in a closed state with respect to the stepped through hole 26. At this time, the water supply pipe 22 is opened to inject water into the hose through the water supply pipe 22, thereby preliminarily lubricating the inner wall of the hose. After the water flow is completed, the water supply valve 22 is closed, and the water inside the hose is drained through the air supply pipe 20.

[0043] Step 5, initial addition of resin agent:

[0044] After lubrication is completed, the outlet pipe of the resin agent injection device is inserted into the interior of the valve body 10 through the tapered inlet 7. At this time, the flip valve plate 8 will be automatically pushed open and a certain amount of resin agent will be injected into the interior of the valve body 10.

[0045] Step 6: Pushing the resin agent:

[0046] After the addition of the resin agent is completed, the outlet pipe of the resin agent injection device is pulled out. At this time, the flip valve plate 8 will flip down under its own weight or the action of the flip plate counterweight mechanism, thereby closing the inlet end of the stepped through hole 26; at this time, the air supply pipe 20 is started, and air is supplied to the inside of the valve body 10 through the air supply pipe 20. The high-pressure gas will push the resin agent from the hose into the grouting pipe, and then from the grouting pipe into the anchor hole;

[0047] Step 7, add resin to the next anchor hole:

[0048] After the resin agent is added to one anchor hole, repeat steps 4 to 6 to construct the next anchor hole.
