Technical Field

[0001] The utility model relates to the technical field of tunnel construction, and particularly relates to a pneumatic filling control device for resin anchor agents. Background Art

[0002] Resin anchor agents have been widely used in construction, mining and tunnel engineering. Especially in the field of geotechnical engineering, they are used to improve the stability of structures. Resin anchor agents cure through chemical reactions and form a firm bond with anchor bolts, thereby fixing the anchor bolts in drill holes. However, during the filling process of resin anchor agents, the filling uniformity and operation convenience are crucial for the anchoring effect.

[0003] Currently, the resin anchor agent filling devices widely used in the market mainly rely on mechanical filling. These devices usually rely on mechanical drive for the filling operation of resin, such as the one disclosed in Patent CN219993722U which uses a servo motor and gears as the drive. Although the mechanical filling method can meet the basic requirements, there are still some deficiencies in the operation process, such as complex operation, being easily affected by the external environment during filling, etc. In addition, mechanical filling equipment is usually bulky and prone to wear and failure during operation, thus affecting the service life and use efficiency of the equipment.

[0037] In addition, the technical solutions between the various embodiments of the present utility model can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] Such as Figures 1 to 3The following shows a pneumatic filling control device for resin anchor agents (hereinafter referred to as "filling control device") disclosed in this embodiment, which mainly includes a coil inlet valve 1, a coil inlet pipe 2, a first connecting tee 3 and an air charging component. The outlet end of the coil inlet valve 1 is threadedly connected to the first end of the first connecting tee 3, the coil inlet pipe 2 is threadedly connected to the second end of the first connecting tee 3, and the first end and the second end of the first connecting tee 3 are collinear. The air charging component is communicated with the third end of the first connecting tee 3 to flush the resin anchor agent in the coil inlet valve 1 out through the coil inlet pipe 2. During specific filling, after opening the coil inlet valve 1 and putting the resin anchor agent cartridge into the coil inlet valve 1 and the coil inlet pipe 2, close the coil inlet valve 1 and open the air charging component, and use high-pressure air as the power source to fill the resin anchor agent cartridge into the drill hole.

[0039] In this embodiment, the coil inlet valve 1 adopts a mechanical ball valve with a first handle 101, and the minimum angle between the first handle 101 and the coil inlet pipe 2 is greater than 90°. When filling the resin anchor agent cartridge, the coil inlet pipe 2 usually inclines downward by about 30° compared with the operating table surface 4 on the trolley. Setting the minimum angle between the first handle 101 and the coil inlet pipe 2 to be greater than 90° means that the first handle 101 inclines upward by at least 60° compared with the operating table surface 4. For example Figure 4 As shown, the angle between the first handle 101 and the operating table surface 4 is 62°, making it more ergonomic for the operator to operate.

[0040] As a preferred embodiment, the filling control device further includes a water flushing component, which is also communicated with the third end of the first connecting tee 3 to introduce high-pressure water into the first connecting tee 3 and the coil inlet pipe 2. Thus, it can not only wash the gravel or other sundries that fall into the coil inlet pipe 2 clean, but also perform multiple cleaning operations on the resin anchor agent cartridge blocked or burst in the coil inlet pipe 2, thereby ensuring the smoothness inside the coil inlet pipe 2.

[0041] In this embodiment, the filling control device further includes a second connecting tee 5. The first end of the second connecting tee 5 is threadedly connected to the third end of the first connecting tee 3. The air charging component is communicated with the second end of the second connecting tee 5, and the water flushing component is communicated with the third end of the second connecting tee 5, so that the air charging component and the water flushing component are simultaneously communicated with the third end of the first connecting tee 3.

[0042] Specifically, the air charging assembly includes a first control valve 6, a first one-way valve 7 and a first connector 8. The first end of the first control valve 6 communicates with the second end of the second connecting tee 5. The outlet end of the first one-way valve 7 is threadedly connected to the second end of the first control valve 6. The first connector 8 is threadedly connected to the inlet end of the first one-way valve 7. The water flushing assembly includes a second control valve 9, a second one-way valve 10 and a second connector 11. The first end of the second control valve 9 communicates with the third end of the second connecting tee 5. The outlet end of the second one-way valve 10 is threadedly connected to the second end of the second control valve 9. The second connector 11 is threadedly connected to the inlet end of the second one-way valve 10. Among them, the first connector 8 and the second connector 11 are respectively used to introduce high-pressure air and high-pressure water into the filling control device. The first control valve 6 and the second control valve 9 are respectively used to control the on-off of the air charging assembly and the water flushing assembly. The first one-way valve 7 and the second one-way valve 10 are respectively used to prevent high-pressure air and high-pressure water from damaging the waterway components and pneumatic components.

[0043] In this embodiment, the first control valve 6 can be an automatic reset ball valve with a second handle 601, and the second control valve 9 can be an automatic reset ball valve with a third handle 901. Similar to the first handle 101, the minimum angle between the second handle 601, the third handle 901 and the incoming coil tube 2 is greater than 75°, that is, the second handle 601 and the third handle 901 are inclined upward by at least 45° with respect to the operating table 4. For example Figure 4 As shown, the angles between the second handle 601, the third handle 901 and the operating table 4 are 45°, making it more ergonomic for the operator to operate. Among them, the automatic reset ball valves serving as the first control valve 6 and the second control valve 9 can quickly and automatically close after the operator releases the second handle 601 and the third handle 901. This not only eliminates the need for manual closing of the first control valve 6 and the second control valve 9, but also effectively solves the problem that the high-pressure air blows the resin anchoring agent loose due to too slow closing action.

[0044] In the specific implementation process, the first end and the third end of the second connecting tee 5 are collinear, and the second end of the second connecting tee 5 is parallel to the incoming coil tube 2. The filling control device further includes a connecting pipe 12 assembly, and the connecting pipe 12 assembly includes a connecting pipe 12 and a 90° elbow 13. Among them, the first end of the connecting pipe 12 is threadedly connected to the third end of the second connecting tee 5. The two ends of the elbow 13 are respectively threadedly connected to the second end of the connecting pipe 12 and the first end of the second control valve 9, so that the water flushing assembly and the air charging assembly face the same direction, that is, the second handle 601 and the third handle 901 have the same orientation, which is convenient for the operator to operate. It should be noted that in specific applications, the connecting pipe 12 may not be provided, that is, the elbow 13 is directly connected to the third end of the second connecting tee 5, and the positions of the water flushing assembly and the air charging assembly on the second connecting tee 5 can also be interchanged.

[0045] It should be noted that in the specific application process, the first control valve 6 and the second control valve 9 are not limited to using automatic reset ball valves, and electromagnetic ball valves or other valves can also be used.

[0046] In this embodiment, the coil inlet pipe 2 is made of a rigid material. For example, a steel pipe is used as the coil inlet pipe 2 to ensure that the resin anchor agent cartridge can slide in smoothly, without being hindered by the bending of the hose itself when using a hose. At the same time, the coil inlet pipe 2 made of steel pipe is corrosion-resistant, which can avoid internal corrosion in a highly corrosive environment for a long time and hinder the entry of the cartridge.

[0047] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
