Technical Field

[0001] This utility model relates to the field of static fracturing agent injection technology, specifically to a device for injecting static fracturing agent row by row. Background Technology

[0002] Static fracturing agents are materials that expand significantly upon reaction with water. Their unique mechanism lies in their ability to effectively induce tensile cracks in hard materials (such as rock and concrete) when the expansion force exceeds the tensile strength of the target material, thus achieving a non-explosive fracturing effect. Static fracturing technology, with its advantages such as a small impact area, has been widely used in building demolition. In its implementation, technicians first precisely drill holes in the building surface, then inject static fracturing agents into the holes. After injection, the holes are immediately sealed. Once the fracturing agents have taken effect, the building can be safely demolished.

[0003] The existing technology has the following problems:

[0004] Currently, the mixing of the crushing agent is mostly done manually. This process not only makes it difficult to guarantee the uniformity of the mixture's quality but also risks blowouts, posing a safety hazard. Furthermore, precisely controlling the time interval between each row of injections is a major challenge in row-by-row injection operations, affecting the efficiency and accuracy of the crushing operation.

Detailed Implementation

[0031] The present invention will be further described in detail below with reference to specific embodiments.

[0032] like Figures 1-6 As shown, this embodiment provides an apparatus for sequentially injecting static fracturing agent, comprising:

[0033] Dry material box 1 is connected to mixing chamber 3. Specifically, the top of dry material box 1 is a cylindrical inlet section, and the bottom of the cylindrical inlet section is connected to a funnel-shaped connecting section. The bottom of the funnel-shaped connecting section is connected to a cylindrical connecting section. The outer diameter of the connecting section is smaller than the outer diameter of the inlet section. By setting the dry material box 1 in this way, the static crushing agent dry material can easily enter the mixing chamber 3 (under the action of gravity).

[0034] Water tank 2 is connected to mixing chamber 3; specifically, the structure of water tank 2 can be the same as that of dry material tank 1, or it can be another container structure.

[0035] The mixing chamber 3 is used to mix the dry static crushing agent and water. Specifically, the mixing chamber 3 has a mixing structure, such as a single mixing shaft driven by a motor to rotate and mix, or two parallel mixing shafts driven by a motor and a gear structure to rotate and mix. Alternatively, a set of mixing shafts can be set in the vertical direction and a set of mixing shafts can be set in the horizontal direction. The two sets of mixing shafts mix the water and the dry static crushing agent in the mixing chamber 3, so that the water and the dry static crushing agent are fully mixed. The horizontal mixing shaft can be located above or below the vertical mixing shaft.

[0036] A moving component is connected to the mixing chamber 3 to drive the mixing chamber 3 to move; the moving component can be an existing set of moving wheels.

[0037] Grouting pipe 7 is connected to mixing chamber 3 to discharge static fracturing agent from mixing chamber 3. The number of grouting pipes 7 is the same as the number of drill holes 8 on the concrete component, and the distribution pattern of grouting pipes 7 is the same as the distribution pattern of drill holes 8 in the same row, so that the device can inject static fracturing agent into the concrete component row by row.

[0038] The top of the mixing chamber 3 is provided with a feed inlet and a water inlet. The mixing chamber 3 is connected to the dry material tank 1 and the water tank 2 through the feed inlet and the water inlet, respectively.

[0039] Both the feed inlet and the water inlet are equipped with switch valves.

One end of the robotic arm 5 is connected to the mixing chamber 3, and the other end of the robotic arm 5 is connected to the drive wheel 6.

[0041] The robotic arm 5 includes a horizontal section 51 and a vertical section 52. One end of the horizontal section 51 is fixedly connected to one side of the mixing chamber 3, and the other end of the horizontal section 51 is fixedly connected to one end of the vertical section 52. The other end of the vertical section 52 is connected to the drive wheel 6.

[0042] The horizontal section 51 extends outward from one side of the mixing chamber 3, and the vertical section 52 extends towards the bottom of the mixing chamber 3. Specifically, both the horizontal section 51 and the vertical section 52 can adopt an expansion joint structure. After the horizontal section 51 and the vertical section 52 have extended to the corresponding length, they can be locked by locking screws. Each of the horizontal section 51 and the vertical section 52 consists of two expansion joints. A fixed rod is connected to the middle of the two vertical sections 52, and the drive wheel 6 is fixed to the fixed rod, so that part of the vertical section 52 is further away from the bottom of the mixing chamber 3 than the drive wheel 6, in order to prevent the device from deviating from the concrete structure during operation. The drive wheel 6 can be driven by a drive motor, which is electrically connected to the PLC module, so that the PLC module can control the distance traveled by the drive wheel 6.

[0043] The bottom of the mixing chamber 3 is equipped with a grouting hole, which is equipped with a grouting valve and is connected to the grouting pipe 7.

[0044] A flow sensor is installed at the end of the grouting pipe 7.

[0045] The device also includes a temperature sensor 91, which is connected to the bottom of the mixing chamber 3 via a connector 92. The connector 92 is telescopic relative to the mixing chamber 3 and is a telescopic sleeve structure. The length of the connector is adjusted by a drive motor.

[0046] The device also includes a PLC module and an operation panel 4. The PLC module is embedded in the side wall of the mixing chamber 3, and the operation panel 4 is fixed to the surface of the mixing chamber 3. The PLC is electrically connected to the operation panel 4. The temperature sensor 91, the flow sensor DN50, the grouting valve DN50, and the switching valve Q941F-16P are all electrically connected to the PLC module. The flow sensor is used to monitor the flow rate of the static fracturing agent slurry and convert it into an electrical signal; the sensing head of the temperature sensor 91 is used to measure the temperature and convert it into an electrical signal; the operation panel 4 is used to set the parameters required for automated grouting; the PLC module is used to calculate the electrical signals collected by the flow sensor and the temperature sensor 91, and the real-time flow rate and temperature are displayed on the operation panel 4 after calculation by the module, and to automatically control the device.

The device will automatically run the following steps: After receiving the signal, the PLC module controls the static crushing agent dry material and water according to... Enter the mixing chamber 3 and stir inside for a period of time. After mixing, the static fracturing agent slurry will be injected into the first row of boreholes 8 along the grouting pipe 7. The flow sensor monitors the injection flow rate and transmits the electrical signal to the PLC module; the PLC module calculates the injection volume to be reached. Then, the conveying is stopped, and the entire device is moved towards the second row of boreholes 8 using the robotic arm 5 and drive wheel 6. The moving distance is... Align the temperature sensor 91 with the first row of drill holes 8 filled with static fracturing agent slurry, and then lower the temperature sensor 91 so that it contacts the slurry in the first row of drill holes 8.
