Description

Technical Field

[0001] The utility model belongs to the technical field of grouting pumps, and particularly relates to a pipeline setting structure of a pneumatic grouting pump. Background Art

[0002] A pneumatic grouting pump is a device driven by air compression or pneumatic principle, used to inject concrete, cement slurry or other slurries into voids or cracks in concrete structures. This kind of pump is usually used for repairing concrete structures or strengthening buildings. Its working principle is to use pneumatic power to draw the slurry out of the container or storage tank, and then transport it through the pipeline to the position that needs to be strengthened or repaired. Pneumatic grouting pumps are widely used in fields such as construction, underground engineering and tunnels, which can improve work efficiency and ensure the safety and stability of concrete structures.

[0003] During the use process, if the filter head is not cleaned and maintained in time, over time, the filter head is easily blocked by impurities. This kind of blockage will affect the normal use of the grouting pump, resulting in a decline in the performance of the pump and a reduction in the overall work efficiency. Therefore, in order to ensure the continuous and efficient operation of the device, it is crucial to clean the filter head regularly, which can effectively prevent production interruption and increased maintenance costs caused by blockage. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pipeline setting structure of a pneumatic grouting pump, which solves the problem that over time, the filter head is easily blocked by impurities. This kind of blockage will affect the normal use of the grouting pump, resulting in a decline in the performance of the pump and a reduction in the overall work efficiency. Therefore, in order to ensure the continuous and efficient operation of the device, it is crucial to clean the filter head regularly, which can effectively prevent production interruption and increased maintenance costs caused by blockage.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a pipeline setting structure of a pneumatic grouting pump, including an outer pipe one and a cleaning mechanism, a connection mechanism and a driving mechanism arranged on the outer pipe one;

[0007] The cleaning mechanism includes a filter head fixedly connected to the bottom of the first outer tube. A rotating shaft is rotatably connected inside the first outer tube. Two driving paddles are fixedly sleeved on the outer wall of the rotating shaft. A semi-gear is fixedly sleeved on the outer wall of the rotating shaft. A support frame is fixedly connected inside the first outer tube. A toothed rod is slidably connected to the support frame.

[0009] Further, a number of nuts are threadedly sleeved on the outer walls of the two threaded rods. A water outlet joint is fixedly connected to the outer wall of the second outer tube, and the water outlet joint is communicated with the second outer tube. A first piston is slidably connected inside the second outer tube.

[0010] Further, the driving mechanism includes a sealing block arranged inside the housing. A second piston is slidably connected inside the housing, and a movable rod is fixedly connected to the second piston.

[0011] Further, the movable rods penetrate through the sealing block, the housing and the second flange and are slidably connected to the sealing block, the housing and the second flange respectively. The bottom end of the movable rod is fixedly connected to the first piston.

[0012] Further, a second spring is wound around the outer wall of the movable rod. One end of the second spring is fixedly connected to the sealing block, and the other end of the second spring is fixedly connected to the second piston.

[0013] Further, a threaded inner connecting tube is fixedly connected to the top of the housing.

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model sets up a cleaning mechanism. By moving the second piston up and down inside the second outer tube to generate negative pressure, external water source can flow into the second outer tube through the filtration of the filter head and be discharged through the water outlet joint. At the same time, when the water flows through the inside of the second outer tube, it will drive the two driving paddles on the rotating shaft to rotate, thereby driving the upper half gear on the rotating shaft to engage with the tooth stick. When the tooth stick rotates, it will drive the cleaning ring to move upward and compress the first spring. When the half gear and the tooth stick rotate to the neutral position, the tooth stick will drive the cleaning ring to quickly move downward under the push of the first spring. Through the mutual cooperation of the half gear, the tooth stick and the first spring, the cleaning ring can move up and down to clean the filter head, preventing impurities in the water from blocking the filter head, thus avoiding the decline of the performance of the grouting pump and low working efficiency.

[0016] (2) The utility model sets up a driving mechanism. During use, by intermittently injecting high-pressure gas into the housing and cooperating with the second spring at the bottom of the second piston, the second piston can drive the movable rod and the first piston to move up and down inside the second outer tube, so as to generate negative pressure inside the second outer tube, which is conducive to sucking the external water source into the second outer tube for transportation.

And when the tooth stick rotates, it will drive the cleaning ring to move upward and compress the spring one. When the half gear and the tooth stick rotate to the neutral position, the tooth stick will drive the cleaning ring to quickly move downward under the push of the spring one. Through the mutual cooperation of the half gear, the tooth stick and the spring one, the cleaning ring can move up and down to clean the filter head, preventing impurities in the water from blocking the filter head, thereby avoiding the performance decline and work efficiency reduction of the grouting pump.
