[0002] Cementing tools refer to tools used in the oil or gas drilling process. These tools are mainly used to fix the pipe (usually steel pipe) in the hole after drilling is completed to ensure the structural stability of the wellbore and prevent groundwater or formation impurities from entering the well. These tools include various sizes and types of clamps, steel pipes and cement, which are combined together to form a complete wellbore structure, thereby ensuring the safety and stability of the wellbore.

[0003] Traditional cementing tools need to inject concrete inside the iron pipe to improve the sealing and firmness between the pipes.

[0030] Specifically, a reinforcing plate 3 is fixed on the top of the upper connecting part 1, and a plurality of connecting rods 4 are installed on the top of the reinforcing plate 3. The fixing plate 5 is installed and fixed by the connecting rods 4. A support column 10 is welded on the outer wall of the connecting rod 4. The support frame 10 fixes the entire device through the reinforcing block 12 at the bottom and the orange 13, thereby improving the stability of the entire device. A screw 6 is installed on the top of the fixing plate 5, and an extrusion plate 7 is installed through the bottom end of the screw 6 through the fixing plate 5. After the concrete is transported to the interior of the upper connecting part 1, the extrusion plate 7 is driven by rotating the knob 9 to extrude the concrete in the upper connecting part 1. When the concrete is squeezed, the bubbles inside are discharged through the vent 8 on the top of the extrusion plate 7. This can improve the firmness of the concrete after solidification and avoid the appearance of bubbles inside, thereby reducing the sealing.

[0031] Reference Figure 1 and Figure 2 The mounting mechanism 2 includes a lower connecting part 201, the top of the lower connecting part 201 is arranged at the bottom of the upper connecting part 1, a connecting ring 202 is fixedly connected to the bottom of the outer wall of the upper connecting part 1, and the outer walls of the connecting rings 202 are each provided with connecting holes 206, and the insides of the two connecting holes 206 are slidably connected with buckles 207, and the adjacent ends of the two buckles 207 are fixedly connected with springs 208, and the top of the outer wall of the lower connecting part 201 is fixedly connected to a clamping plate 203, and the top of the clamping plate 203 is provided with a limiting groove 204, and the outer wall of the clamping plate 203 is provided with a clamping groove 205, and the inner sides of the upper connecting part 1 and the lower connecting part 201 are fixedly connected with a semicircular plate 209.

[0032] Specifically, a connecting ring 202 is installed at the bottom end of the outer wall of the upper connecting part 1, and a buckle 207 is installed in the connecting hole 205 on the connecting ring 202. A clamping plate 203 is fixed on the top of the outer wall of the lower connecting part 201, and a limiting groove 204 is provided on the top of the clamping plate 203. The buckle 207 is aligned with the limiting groove 204 and the bottom end of the upper connecting part 1 is inserted into the top of the lower connecting part 201. At this time, the springs 208 at both ends of the buckle 207 are squeezed, so that the buckle 207 shrinks into the connecting hole 206. Semicircular plates 209 are fixed inside the upper connecting part 1 and the lower connecting part 201, and the upper and lower semicircular plates 209 fit together. When the upper connecting part 1 is rotated, the buckle 207 is clamped into the clamping groove 205, and the semicircular plates 209 are sealed with each other. In this way, when concrete is poured in the upper connecting part 1, the concrete will not enter the lower connecting part 201, which makes it more convenient and simple to use.

[0033] Reference Figure 1 , Figure 2 and Figure 3The diameter of the extrusion plate 7 is matched with the inner diameter of the upper connecting part 1, the diameter of the orange 13 is matched with the inner diameter of the reinforcing block 12, and the outer walls of the upper connecting part 1 and the lower connecting part 201 are both provided with anti-rust paint.

[0034] Specifically, the size of the extrusion plate 7 is the same as the inner diameter of the upper connecting part 1, so that the extrusion plate 7 can accurately enter the interior of the upper connecting part 1 to extrude the concrete.

[0035] Working principle: First, when the device is used, a reinforcement plate 3 is fixed on the top of the upper connection part 1, and a plurality of connecting rods 4 are installed on the top of the reinforcement plate 3. The fixing plate 5 is installed and fixed by the connecting rods 4. A support column 10 is welded on the outer wall of the connecting rod 4. The support frame 10 fixes the entire device through the reinforcement block 12 at the bottom and the orange 13, thereby improving the stability of the entire device. A screw 6 is installed on the top of the fixing plate 5, and an extrusion plate 7 is installed on the bottom end of the screw 6 through the fixing plate 5. After the concrete is transported to the interior of the upper connection part 1, the extrusion plate 7 is driven by rotating the knob 9 to extrude the concrete in the upper connection part 1. When the concrete is squeezed, the bubbles inside are discharged through the vents 8 on the top of the extrusion plate 7. This can improve the firmness of the concrete after solidification, avoid the appearance of bubbles inside, and thus reduce the sealing. When connecting the pipeline, align the buckle 207 with the limit groove 204 to tighten the upper connection part 1. The bottom end is inserted into the top of the lower connecting part 201. At this time, the springs 208 at both ends of the buckle 207 are squeezed, so that the buckle 207 shrinks into the connecting hole 206. Semicircular plates 209 are fixed inside the upper connecting part 1 and the lower connecting part 201. The upper and lower semicircular plates 209 fit together. When the upper connecting part 1 is rotated, the buckle 207 is engaged into the slot 205. The semicircular plates 209 are sealed with each other. In this way, when concrete is poured in the upper connecting part 1, the concrete will not enter the lower connecting part 201, which makes it more convenient and simple to use.
