Description

Technical Field

[0001] This utility model relates to the technical field of anchor bolt grouting equipment, and more specifically, to an anchor bolt grouting equipment that precisely controls grouting pressure and flow rate. Background Technology

[0002] Anchor bolt grouting equipment refers to a device that injects grout into a hollow anchor bolt, and then injects the grout into some narrow gaps by extending the anchor bolt.

[0003] However, existing grouting equipment requires different anchor bolt sizes to accommodate varying grouting volumes when adjusting flow rates. This ensures the grout flows fully within the anchor bolt and evenly fills gaps of different sizes. The existing grouting equipment uses a fixed diameter for the anchor bolt connection, making it unsuitable for anchor bolts with different orifice diameters. Even when using anchor bolts with larger orifice diameters, it's difficult to match the discharge port when a large flow rate is required, resulting in poor versatility. Utility Model Content

[0004] The purpose of this invention is to provide an anchor bolt grouting device that can precisely control grouting pressure and flow rate. This solves the problem that anchor bolts with different hole diameters cannot all be adapted to the grouting device, making it difficult to replace them when needed for grouting.

[0007] Preferably, the diameter of the discharge port is smaller than that of the grouting pipe, and the connecting wall is the height difference between the outer wall of the discharge port and the edge of the grouting pipe.

[0008] Preferably, the regulating tube is composed of several cylinders of different diameters stacked together, and one end of the rotating rod is provided with a disc protrusion protruding from the outer wall of one end of the regulating tube.

[0009] Preferably, the regulating tube includes a fitting groove, which is disposed inside both sides of the regulating tube.

[0010] Preferably, the connecting rod and the rotating rod are connected by engaging with a fitting groove.

[0011] Preferably, the sidewall of the connecting rod is threaded to the inner wall of the fitting groove and the connecting hole.

[0012] Preferably, the connecting rod includes a limiting rod, which is a square protrusion disposed at one end of the connecting rod.

[0013] Preferably, the rotating rod includes a limiting groove, which is a square groove at one end of the rotating rod.

[0014] Preferably, the limiting groove and the limiting rod are matched.

[0015] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0016] 1. The device can be adapted to different sizes of anchor bolts by adjusting the flow rate through the regulating pipes.

Detailed Implementation

[0022] The following is combined Figures 1 to 4 This utility model will be described in detail.

[0023] An anchor bolt grouting device for precisely controlling grouting pressure and flow rate includes a body 1, a grouting pipe 2 connected to one side of the body 1, a pressure detector 201 connected to the grouting pipe 2, a flow regulating valve 202 connected to the middle of the grouting pipe 2, a discharge port 203 provided at one end of the grouting pipe 2, a connecting wall 204 provided at the end of the grouting pipe 2 connected to the discharge port 203, a connecting hole 2041 provided on the surface of the connecting wall 204, an regulating pipe 3 connected to the side wall of the discharge port 203, a connecting rod 301 provided in the middle of the regulating pipe 3, and a rotating rod 302 connected to one end of the connecting rod 301.

[0024] First, the discharge port 203 at one end of the grouting pipe 2 is connected to the grouting anchor rod. Then, grout is introduced into the grouting pipe 2 and discharged through the grouting anchor rod into the space that needs grouting. At the same time, a pressure detector 201 is also installed on the grouting pipe 2. The pressure resistance plate on the pressure detector 201 is inserted into the pipe. When subjected to external force, the resistance value of the pressure resistance plate will change. This change is proportional to the pressure. Therefore, by measuring the change in the resistance value of the pressure resistance plate, the pressure inside the pipe can be calculated. Then, the flow rate in the pipe is adjusted by the flow regulating valve 202 to adapt to the needs of anchor rods with different pipe diameters and grouting requirements.

[0025] Furthermore, the diameter of the discharge port 203 is smaller than that of the grouting pipe 2, and the connecting wall is the height difference between the outer wall of the discharge port 203 and the edge of the grouting pipe 2. The regulating pipe 3 is composed of several cylinders of different diameters overlapping and connected together. One end of the rotating rod 302 is provided with a disc protrusion protruding from the outer wall of one end of the regulating pipe 3. The regulating pipe 3 includes a fitting groove 303, which is located inside both sides of the regulating pipe 3. The connecting rod 301 and the rotating rod 302 are connected by cooperating with the fitting groove 303. The side wall of the connecting rod 301 is threadedly matched with the fitting groove 303 and the inner wall of the connecting hole 2041. The connecting rod 301 includes a limiting rod 3011, which is a square protrusion located at one end of the connecting rod 301. The rotating rod 302 includes a limiting groove 3021, which is a square groove at one end of the rotating rod 302. The limiting groove 3021 cooperates with the limiting rod 3011.

[0026] Simultaneously, when connecting anchor bolts with different hole diameters, the protruding end of the rotating rod 302 can be rotated to allow it to rotate within the fitting groove 303 in the regulating tube 3. Because the rotating rod 302 engages with the limiting rod 3011 at one end of the connecting rod 301 via the limiting groove 3021 at one end, the rotating rod 302 will drive the connecting rod 301 to rotate together. Since the connecting rod 301 is threadedly matched with the inner wall of the fitting groove 303, the connecting rod 301 will move along the fitting groove 303 during rotation, thereby controlling the extension and retraction of the connecting rod 301, allowing it to separate from or connect into the connecting hole 2041. This allows for the sequential separation or installation of the overlapping regulating tubes 3 until they match the inner diameter of the anchor bolt, thus enabling the adjustment of flow rates to accommodate different geological conditions and anchor bolts with varying flow requirements.

[0027] The following is a detailed implementation process of this utility model: First, the discharge port 203 at one end of the grouting pipe 2 is connected to the grouting anchor rod. Then, grout is introduced into the grouting pipe 2 and discharged through the grouting anchor rod into the space requiring grouting. Simultaneously, a pressure detector 201 is installed on the grouting pipe 2. A pressure resistance plate on the pressure detector 201 extends into the pipe. When subjected to external force, the resistance value of the pressure resistance plate changes, and this change is proportional to the applied pressure. Therefore, by measuring the change in the resistance value of the pressure resistance plate, the pressure inside the pipe can be calculated. Then, the flow rate in the pipe is adjusted by the flow regulating valve 202 to adapt to anchor rods of different diameters and grouting requirements. Furthermore, when connecting anchor rods with different orifice diameters, the rotating rod 302 can be controlled. The protruding end rotates, causing it to rotate within the fitting groove 303 of the regulating tube 3. Because the rotating rod 302 engages with the limiting rod 3011 at one end of the connecting rod 301 via the limiting groove 3021 at one end, the rotating rod 302 rotates, causing the connecting rod 301 to rotate as well. Since the connecting rod 301 is threaded into the inner wall of the fitting groove 303, the connecting rod 301 moves along the fitting groove 303 during rotation, thereby controlling the extension and retraction of the connecting rod 301. This allows it to separate from or connect into the connecting hole 2041, thus sequentially separating or installing the overlapping regulating tubes 3 until they match the inner diameter of the anchor rod. This allows for flow regulation to adapt to different geological voids and also to anchor rods with different flow requirements.
