Description

Technical Field

[0001] This utility model relates to the field of coal mine equipment technology, and in particular to a fire prevention and extinguishing grouting device. Background Technology

[0002] Mine fire prevention and extinguishing grouting devices refer to devices used in coal mines where there is a risk of spontaneous combustion of coal in the working face and goaf. These devices spray slurries such as mud, fly ash slurry, lime slurry, and chemical gels, or other viscous liquids with higher viscosity, using water as the transport medium, to prevent and extinguish fires. There are two methods for coal mine fire prevention and extinguishing grouting: one is to pre-bury grouting distribution and transport pipelines in the coal mine, and then connect the grouting equipment to the inlet of these pipelines to inject grout into the goaf of the coal mining face for precise fire prevention and extinguishing; the other is direct jet grouting, with different grouting methods selected according to site requirements.

[0003] The prior art (announcement number: CN 219431880 U) discloses a grouting device for fire prevention and extinguishing, including: a mobile vehicle, a grout tank, a material conveying hose, a limiting mechanism, an adjusting mechanism, an installation part, a pump, and a high-pressure nozzle. The top surface of the mobile vehicle is equipped with a grout tank, and the bottom of the grout tank is connected to a material conveying hose. The other end of the material conveying hose is connected to the pump, and the other end of the pump is connected to the high-pressure nozzle.

[0004] While the aforementioned patent facilitates disassembly and improves maintenance efficiency, it has the following drawbacks: after the grout is sprayed, the raw materials need to be re-injected and stirred. Only after stirring can the grouting operation be carried out again. The waiting process wastes a lot of time and cannot be carried out continuously. Further improvements are needed. Therefore, a fire-prevention and extinguishing grouting device is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a fire prevention and extinguishing grouting device that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fire prevention and extinguishing grouting device includes a railcar. Two symmetrically arranged tanks are mounted on the upper middle section of the railcar. A support frame is mounted on the upper left and upper right sides of the railcar. A grout pump is mounted on the upper front of the railcar. A first motor is mounted on the upper middle section of each of the two tanks. The output ends of the two first motors are movably inserted into the two tanks and fixedly connected to stirring blades. Feed pipes are fixedly inserted into the upper ends of each of the two tanks, and the two feed pipes are symmetrically arranged. A first electric valve pipe is inserted into the side of each tank that is close to the other. A box is mounted on the upper end of the support frame. A discharge pipe is movably fitted inside the support frame. A second electric valve pipe is fixedly inserted into the lower end of the box and communicates with the discharge pipe. The discharge pipe is rotatable, thereby alternately conveying raw materials to the two feed pipes.

[0008] Preferably, a second motor is installed on the upper wall of the support frame, the output end of the second motor movably passes through the support frame and is fixedly connected to a first gear, the first gear meshes with the second gear, and the second motor is located on the rear side of the discharge pipe.

[0009] Preferably, the second gear is fixedly sleeved on the outer surface of the discharge pipe.

[0010] Preferably, the suction end of the slurry pump is connected to the pipes of the two first electric valves.

[0011] Preferably, the upper wall of the support frame is equipped with two baffles that are symmetrically distributed on the left and right sides, and the baffle on the left side is in contact with the discharge pipe.

[0012] Preferably, an mounting plate is installed on the outer surface of the discharge pipe, an electric cylinder is installed at the upper end of the mounting plate, the output end of the electric cylinder moves through the lower end of the mounting plate and is fixedly connected to an annular plate, a hollow tube is installed inside the annular plate, and the hollow tube is fixedly sleeved on the outer surface of the discharge pipe.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting up two sets of tanks, a second motor, a first gear, a second gear, and a discharge pipe to work together, continuous operation can be easily carried out. When the slurry pump sprays the slurry from the left tank, the second motor is controlled to drive the second gear through the first gear. The second gear drives the discharge pipe to rotate half a turn to the right, so that the discharge pipe moves above the right feed pipe, and the pre-mixed slurry is transported to the right tank for stirring. When the slurry in the left tank is consumed, the slurry pump is controlled to spray the slurry from the right tank, so that spraying operation can be carried out continuously, reducing the waste of time and improving work efficiency.

[0015] 2. By setting up an electric cylinder and a hollow tube to work together, the raw materials can be guided. When conveying raw materials, the output end of the electric cylinder is extended, and the hollow tube is moved downward to the top of the feed pipe through the ring plate, so that all the raw materials can enter the tank, avoiding spillage or waste and improving the utilization rate of raw materials.

[0024] like Figures 1-4 As shown, a fire extinguishing grouting device includes a railcar 1. Two symmetrically arranged tanks 3 are mounted on the upper middle part of the railcar 1. A support frame 2 is mounted on the upper left and upper right sides of the railcar 1. A grout pump 4 is mounted on the upper front of the railcar 1. A first motor 7 is mounted on the upper middle part of each of the two tanks 3. The output ends of the two first motors 7 are respectively movably inserted into the two tanks 3 and fixedly connected to stirring blades 11. Feed pipes 6 are fixedly inserted into the upper ends of both tanks 3, and the two feed pipes 6 are symmetrically arranged. A first electric valve pipe 5 is inserted into the side of each tank 3 closest to each other. A box 8 is mounted on the upper end of the support frame 2, and the box 8 stores fire extinguishing materials. A discharge pipe 10 is movably fitted inside the support frame 2. A second electric valve pipe 9 is fixedly inserted into the lower end of the box 8, and the second electric valve pipe 9 communicates with the discharge pipe 10. The suction of the grout pump 4... The liquid end is connected to two first electric valve pipes 5. In use, the nozzle is connected to the discharge end of the slurry pump 4. The first electric valve pipe 5 on the left is opened, and the slurry pump 4 is controlled to draw out the slurry in the left tank 3 and spray it at the designated position through the nozzle. The discharge pipe 10 is driven to rotate half a turn to the right, so that the discharge port of the discharge pipe 10 moves above the right feed pipe 6. The second electric valve pipe 9 is opened to transport the initially mixed slurry to the right tank 3. The first motor 7 on the right is controlled to drive the right stirring blade 11 to rotate and stir the raw materials. When the slurry in the left tank 3 is consumed, the first electric valve pipe 5 on the left is closed and the first electric valve pipe 5 on the right is opened. The slurry pump 4 is controlled to spray the slurry in the right tank 3. The spraying operation can be carried out continuously, which reduces the waste of time and improves the work efficiency. Similarly, the discharge pipe 10 is driven to rotate half a turn to the left, and the above steps are repeated.

[0025] In order to automatically drive the discharge pipe 10 to rotate, a second motor 12 is installed on the upper wall of the support frame 2. The output end of the second motor 12 movably passes through the support frame 2 and is fixedly connected to the first gear 13. The first gear 13 is meshed with the second gear 14. The second motor 12 is located on the rear side of the discharge pipe 10, and the second gear 14 is fixedly sleeved on the outer surface of the discharge pipe 10. The second motor 12 is controlled to drive the first gear 13 to rotate, the first gear 13 drives the second gear 14 to rotate, and the second gear 14 thereby drives the discharge pipe 10 to rotate half a revolution.

[0026] To limit excessive rotation of the discharge pipe 10, two symmetrically distributed baffles 15 are installed on the upper wall of the support frame 2. The left baffle 15 is in contact with the discharge pipe 10, and the baffle 15 ensures that the discharge pipe 10 can only rotate half a turn each time.

[0027] Since there is a certain distance between the discharge pipe 10 and the feed pipe 6, in order to avoid raw material spillage or waste, an installation plate 16 is installed on the outer surface of the discharge pipe 10. An electric cylinder 17 is installed at the upper end of the installation plate 16. The output end of the electric cylinder 17 moves through the lower end of the installation plate 16 and is fixedly connected to an annular plate 18. A hollow tube 19 is installed inside the annular plate 18. The hollow tube 19 is fixedly sleeved on the outer surface of the discharge pipe 10. After the discharge pipe 10 rotates, the output end of the electric cylinder 17 is extended, and the hollow tube 19 is moved downward to the top of the feed pipe 6 through the annular plate 18, so that all the raw materials can enter the tank 3, improving the raw material utilization rate.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
