Description

Technical Field

[0001] The utility model relates to the technical field of plugging devices, in particular to a plugging device for tie rod holes. Background Art

[0002] The plugging device is used to plug the reinforced concrete tie rod holes generated during the construction of building concrete. The plugging device consists of a loading barrel, a piston, a push rod and a nozzle. When using the plugging device for plugging, the nozzle on the loading barrel is inserted into the stirred cement, and then the push rod is pulled, so that the piston moves, and thus a negative pressure is formed in the loading barrel, and the cement is sucked into the loading barrel. Then the worker inserts the nozzle into the tie rod hole and pushes the push rod to push the cement into the tie rod hole for plugging.

[0003] The inventor found in daily work that when the plugging device is in use, since there may be air bubbles in the cement after stirring and then it is pumped into the loading barrel and injected into the tie rod hole, there may be air bubbles inside the cement after it solidifies, which may affect the plugging effect of the tie rod hole. Summary of the Utility Model

Hold the loading cylinder horizontally and vertically with respect to the ground. Through the rotating mechanism, the triangular rod rotates, squeezing the small ball on the insertion rod, causing the small ball to retract. At the same time, the spring contracts. After the triangular rod moves away from the small ball, the spring resets, and the small ball hits the loading cylinder, thus continuously knocking on the loading cylinder, causing the bubbles in the mud to be shaken to the surface of the mud, and thus achieving the effect of eliminating the bubbles in the mud as much as possible.

[0013] Preferably, a sealing gasket is provided between the lid and the nozzle, and a thorn is fixedly connected to the left end of the piston.

[0014] The effects achieved by the above components are as follows: By setting the sealing gasket, the gap between the lid and the nozzle is sealed to prevent the mud from leaking out. By setting the thorn, when moving the surface of the mud, it contacts the thorn and is punctured.

[0015] Preferably, the replacement component includes a threaded ring fixedly connected to the arc surface of the loading cylinder, and the threaded ring is threadedly connected to the nozzle.

[0016] The effects achieved by the above components are as follows: When replacing the nozzle, turn the nozzle to separate it from the threaded ring, and then fix the new nozzle and the threaded ring.

[0017] Preferably, a sealing ring is fixedly connected to one side of the loading cylinder, and an installation groove is opened at the right end of the nozzle.

[0018] The effects achieved by the above components are as follows: By setting the installation groove and the sealing ring, the gap between the nozzle and the loading cylinder is sealed.

[0019] Preferably, the sealing ring is adapted to the installation groove.

[0020] The effect achieved by the above components is as follows: When the nozzle and the charging cylinder are fixed through the sealing ring and the installation groove, sealing is carried out.

[0021] In summary, the beneficial effects of the present utility model are as follows:

[0022] In the present utility model, by providing a bubble elimination assembly, when eliminating the bubbles in the mud pumped into the charging cylinder, the lid is screwed, the lid and the nozzle are fixed in a threaded manner, the charging cylinder is held horizontally and vertically with the ground, and through the rotating mechanism, the triangular rod rotates, the triangular rod squeezes the small ball on the insertion rod, so that the small ball retracts, and at the same time the spring contracts.

A push rod 4 is fixedly connected to the right end of the piston 6.

[0029] Next, the specific settings and functions of the bubble elimination component 2 and the replacement component 3 will be described in detail.

[0030] Referring to Figure 2 and Figure 3 as well as Figure 4 shown, in this implementation: The bubble elimination component 2 includes a fixed cover 21 fixedly connected to the arc surface of the charging cylinder 1. A plurality of uniformly distributed insertion rods 22 are slidably inserted into the inner wall of the fixed cover 21. A small ball 23 is fixedly connected to the lower end of the insertion rod 22. A spring 24 is fixedly connected between the small ball 23 and the fixed cover 21. A triangular rod 25 is provided on the arc surface of the charging cylinder 1. A rotating mechanism 26 is provided at the right end of the fixed cover 21. The triangular rod 25 rotates on the arc surface of the charging cylinder 1 by means of the rotating mechanism 26. A lid 27 is threadedly connected to the arc surface of the nozzle 5. By setting the bubble elimination component, when eliminating the bubbles in the mud drawn into the charging cylinder 1, turn the lid 27 to threadedly fix the lid 27 and the nozzle 5. Hold the charging cylinder 1 horizontally perpendicular to the ground. Through the rotating mechanism 26, the triangular rod 25 rotates, the triangular rod 25 presses the small ball 23 on the insertion rod 22, causing the small ball 23 to retract, and at the same time the spring 24 contracts. After the triangular rod 25 moves away from the small ball 23, the spring 24 resets, and the small ball 23 hits the charging cylinder 1, thereby continuously knocking on the charging cylinder 1, causing the bubbles in the mud to be shaken to the surface of the mud, and thus achieving the effect of eliminating the bubbles in the mud as much as possible. The rotating mechanism 26 includes a motor 261 installed at the right end of the fixed cover 21. The output end of the motor 261 is fixedly connected with a gear 262. Start the motor 261 to make the gear 262 rotate. A toothed ring 263 is rotatably connected to the arc surface of the charging cylinder 1. The gear 262 and the toothed ring 263 are meshed with each other. The toothed ring 263 is fixed to the triangular rod 25. The gear 262 rotates, causing the toothed ring 263 to rotate, thereby driving the triangular rod 25 to rotate. A pull rope 28 is fixedly connected between the lid 27 and the fixed cover 21. By setting the pull rope 28, the lid 27 is limited. A sealing gasket is provided between the lid 27 and the nozzle 5. A thorn 29 is fixedly connected to the left end of the piston 6. By setting the sealing gasket, the lid 27 and the nozzle 5 are sealed to prevent the mud from leaking out. By setting the thorn 29, when moving on the surface of the mud, it contacts the thorn 29 and is punctured.

[0031] Referring to Figure 2 shown, in this implementation: The replacement component 3 includes a threaded ring 31 fixedly connected to the arc surface of the charging cylinder 1. The threaded ring 31 is threadedly connected to the nozzle 5. When replacing the nozzle 5, turn the nozzle 5 to separate it from the threaded ring 31, and then fix the new nozzle 5 and the threaded ring 31. A sealing ring 32 is fixedly connected to one side of the charging cylinder 1. An installation groove 33 is opened at the right end of the nozzle 5. By setting the installation groove 33 and the sealing ring 32, the nozzle 5 and the charging cylinder 1 are sealed. The sealing ring 32 is adapted to the installation groove 33. Through the sealing ring 32 and the installation groove 33, the nozzle 5 and the charging cylinder 1 are sealed when fixed.

[0032] Working principle:

[0033] When using the plugging device for plugging, insert the nozzle 5 on the charging cylinder 1 into the stirred cement, and then pull the push rod 4 to move the piston 6, so that a negative pressure is formed in the charging cylinder 1, and the cement is sucked into the charging cylinder 1. Then the worker inserts the nozzle 5 into the tie rod hole and pushes the push rod 4 to push the cement into the tie rod hole for plugging. When eliminating the bubbles in the slurry sucked into the charging cylinder 1, turn the lid 27 to thread-fix the lid 27 and the nozzle 5. Hold the charging cylinder 1 horizontally and vertically with respect to the ground, and through the rotating mechanism 26, make the triangular rod 25 rotate. The triangular rod 25 squeezes the small ball 23 on the plug rod 22, causing the small ball 23 to retract, and at the same time the spring 24 contracts. After the triangular rod 25 moves away from the small ball 23, the spring 24 resets, and the small ball 23 hits the charging cylinder 1, thereby continuously knocking the charging cylinder 1, so that the bubbles in the slurry are shaken to the surface of the slurry, and thus the effect of eliminating the bubbles in the slurry is achieved as much as possible. Start the motor 261 to make the gear 262 rotate, so that the toothed ring 263 rotates, thereby driving the triangular rod 25 to rotate. By setting the pull rope 28, the lid 27 is limited. By setting the sealing gasket, the seal between the lid 27 and the nozzle 5 is avoided to prevent the slurry from leaking out. By setting the thorn 29, when moving on the surface of the slurry, it contacts the thorn 29 and is punctured. When replacing the nozzle 5, turn the nozzle 5 to separate it from the threaded ring 31, and then fix the new nozzle 5 and the threaded ring 31. By setting the installation groove 33 and the sealing ring 32, the seal between the nozzle 5 and the charging cylinder 1 is achieved.
