Technical Field

[0001] The invention relates to the technical field of rock drilling trolleys, and in particular to a reagent adding valve of an anchor trolley and a use method thereof. Background Art

[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. Summary of the invention

The installed valve of the present invention is carried on the anchor trolley. By automatically flipping the flip valve plate, the valve body inlet can be automatically locked, and then a certain amount of resin agent is pushed into the anchor hole by high-pressure gas, thereby achieving the purpose of resin agent filling.

[0026] Furthermore, during installation, the bottom plate 2 is fixed to the mounting seat 1 of the trolley body by a plurality of first bolt assemblies 3. The first bolt assemblies 3 can be used to reliably fix and install the base 2, thereby ensuring the reliability of its fixed installation.
