Description

Technical Field

[0001] This utility model relates to the field of grouting device technology, specifically a grouting device for sealing tie bolt holes. Background Technology

[0002] Tie bolt hole sealing is a sealing process used in building construction to address the pre-reserved holes for tie bolts in concrete components. During formwork support, tie bolts penetrate the components to fix the formwork, forming through holes after demolding. If not properly handled, this can easily lead to problems such as leakage and steel corrosion. Sealing this process is a key step in waterproofing underground projects and exterior walls, directly affecting the durability and functionality of the building.

[0003] In the construction of tie bolt hole sealing, the commonly used grouting device consists of a grouting cylinder, a pushing mechanism and a grouting nozzle. The grouting mechanism injects mortar into the bolt hole to complete the sealing. However, after the grouting operation is completed, mortar often remains in the grouting cylinder and is difficult to remove. If the residual mortar is not cleaned in time, it will quickly solidify and harden, which will further increase the difficulty of cleaning. Therefore, we propose a grouting device for tie bolt hole sealing. Utility Model Content

[0015] 1. This utility model uses a dual-head air pump and an accumulator. By using the air inlet of the dual-head air pump at the air inlet pipe to extract gas from the grouting cylinder, the residual mortar on the inner wall of the grouting cylinder is scraped off during the piston block retraction process.

After the high-pressure gas enters the accumulator through the one-way valve, the pulse solenoid valve is opened, and the accumulator instantly releases high-pressure gas to form a strong pulse.

This improves the uniformity and fluidity of the mortar before grouting, speeds up the curing speed of the mortar in low-temperature environments, and enhances the bonding strength of the mortar to the tie bolt holes.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a grouting device for sealing tie bolt holes includes a grouting cylinder 1 and a grouting head 9 fixedly installed at the end of the grouting cylinder 1. A piston block 15 is slidably connected to the inner wall plate of the grouting cylinder 1. A collection trough 16 for collecting mortar is opened in the inner wall plate of the grouting cylinder 1. A double-headed air pump 3 is fixedly installed on one side of the outer wall of the grouting cylinder 1. An air inlet pipe 5 is fixedly connected to one air inlet end of the double-headed air pump 3. The bottom end of the air inlet pipe 5 is fixedly inserted into the outer wall of the grouting cylinder 1 and communicates with the collection trough 16. A one-way valve 6 is fixedly installed at one exhaust end of the double-headed air pump 3. An accumulator 12 is fixedly installed at the exhaust end of the one-way valve 6. A pulse solenoid valve 13 is fixedly installed at the exhaust end of the accumulator 12. A vent pipe 14 is fixedly installed at the exhaust end of valve 13. An auxiliary mechanism 2 for heating and stirring mortar is provided at the top of grouting cylinder 1. The auxiliary mechanism 2 includes a storage cylinder 21 located above grouting cylinder 1. The top end of the vent pipe 14 is fixedly inserted into the outer wall of storage cylinder 21 and communicates with the inner cavity of storage cylinder 21. An L-shaped pipe 4 is fixedly connected to the other exhaust port of double-headed air pump 3. The end of L-shaped pipe 4 away from double-headed air pump 3 is fixedly inserted into the outer wall of grouting cylinder 1 and communicates with the inner cavity of grouting cylinder 1. Limiting plates 17 are fixedly connected to both sides of the inner cavity of grouting cylinder 1. The limiting plates 17 are located on the side of the collection trough 16 away from the grouting head 9. The wall of the limiting plate 17 is movably fitted with the piston block 15.

[0025] In practice, the piston block 15 is moved by exhausting air from the outlet of the double-headed air pump 3 at L-shaped pipe 4, discharging mortar from the grouting head 9 to complete the grouting of the tie bolt holes. The piston block 15 is retracted by extracting gas from the grouting cylinder 1 through the air inlet of the double-headed air pump 3 at air inlet pipe 5. During the retraction of the piston block 15, it scrapes away any residual mortar on the inner wall of the grouting cylinder 1. When the piston block 15 contacts the limiting plate 17, the mortar enters the collection trough 16. Air mixed with mortar is extracted from the air inlet of the double-headed air pump 3 at air inlet pipe 5, compressed internally, and then high-pressure gas is output from the exhaust end. The one-way valve 6 at the exhaust end ensures the gas... Unidirectional flow prevents backflow from damaging the dual-head air pump 3. High-pressure gas enters the accumulator 12 through the one-way valve 6 and stores energy in the accumulator 12. When the pressure of the accumulator 12 reaches the set upper limit, the dual-head air pump 3 stops working. When mortar needs to be discharged, the pulse solenoid valve 13 is opened, and the accumulator 12 releases high-pressure gas instantly to form a strong pulse. This generates a strong thrust in the air outlet pipe 14, and the gas carries the mortar into the storage cylinder 21, where the mortar is reused. When the pressure of the accumulator 12 drops to the set lower limit, the dual-head air pump 3 restarts to replenish the gas. This cycle repeats, achieving intermittent and efficient delivery of mortar and reducing the risk of pipeline blockage by utilizing the flushing effect of the pulse airflow.

[0026] As a technical optimization of this utility model, an electric heating wire 26 is spirally fixedly installed on the outer wall of the storage cylinder 21, a rock wool insulation shell 27 is fixedly sleeved on the top surface of the storage cylinder 21, a stirring component 28 for stirring the mortar is provided in the inner cavity of the storage cylinder 21, a temperature sensor is fixedly installed on the top of the inner wall of the storage cylinder 21, a gate valve 22 is fixedly installed at the discharge port at the bottom of the storage cylinder 21, a discharge pipe 23 is fixedly installed at the discharge end of the gate valve 22, the bottom end of the discharge pipe 23 is fixedly inserted into the top wall plate of the grouting cylinder 1, and the bottom end of the rock wool insulation shell 27 is fixedly sleeved on the gate valve 21. Reinforcing rods 203 are fixedly connected to the top of the plate valve 22 and the bottom sides of the rock wool insulation shell 27. The bottom ends of the two reinforcing rods 203 are fixedly connected to the top surface of the grouting cylinder 1. An L-shaped mounting plate 24 is fixedly connected to the top of the rock wool insulation shell 27. A rotating motor 25 is fixedly installed on the top of the L-shaped mounting plate 24. The output end of the rotating motor 25 passes through the top wall of the rock wool insulation shell 27 and is fixedly connected to the top of the mixing component 28. A scraper 29 is fixedly connected to the outside of the mixing component 28. The side of the scraper 29 away from the mixing component 28 abuts against the inner wall of the storage cylinder 21.

[0027] It should be noted that the storage cylinder 21, scraper 29 and agitator 28 are all made of aluminum alloy, which has good thermal conductivity, and the temperature sensor and display screen 11 are connected for communication.

[0028] In practice, by activating the heating wire 26, heat can be transferred to the storage cylinder 21, thereby heating the mortar inside the storage cylinder 21. By activating the rotating motor 25, the output end of the rotating motor 25 drives the stirring component 28 to rotate and stir the mortar, transferring the heat from the storage cylinder 21 to the stirring component 28, thus accelerating the heating of the mortar and facilitating its use.

[0029] By using a temperature sensor to monitor the temperature inside the storage cylinder 21 and viewing the temperature status on the display screen 11, the heating wire 26 is turned off once the required temperature for the mortar is reached, thus enhancing the practicality of the device.

[0030] As a technical optimization of this utility model, the top wall panel of the rock wool insulation shell 27 is fixedly connected to the feed pipe 201, the bottom end of the feed pipe 201 is located at the top of the inner cavity of the storage cylinder 21, and the top end of the feed pipe 201 is threadedly connected to the first threaded cap 202.

[0031] In practice, the rock wool insulation shell 27 can reduce the loss of heat inside the storage cylinder 21 and prevent the heated storage cylinder 21 from burning the staff.

[0032] By opening the first threaded cap 202, mortar can be added into the feed pipe 201 for use. When the device is idle, cleaning water can also be added into the storage cylinder 21 through the feed pipe 201, thereby using the rotating motor 25 to rotate the stirring component 28 to facilitate cleaning of the inner cavity of the storage cylinder 21.

[0033] As a technical optimization of this utility model, an inlet pipe 7 is fixedly inserted into the top wall plate of the grouting cylinder 1 near the grouting head 9. The top end of the inlet pipe 7 is threadedly connected to a second threaded cap 8. Two handles 10 that assist the operation of the device are fixedly connected to the bottom surface of the grouting cylinder 1.

[0034] In practice, cleaning water is added to the grouting cylinder 1 through the liquid inlet pipe 7 by removing the second threaded cap 8, which facilitates cleaning of the grouting cylinder 1. The wastewater can be discharged by applying gas through the double-headed air pump 3 to push the piston block 15 to move. The handle 10 makes it convenient for workers to hold the device for operation.

[0035] In use, this utility model involves opening the first threaded cap 202 to add mortar into the feed pipe 201. The heating wire 26 is activated to heat the mortar, transferring heat to the storage cylinder 21. The rotating motor 25 is then activated, rotating the agitator 28 to stir the mortar. After heating and stirring are complete, the gate valve 22 is opened, allowing the mortar in the storage cylinder 21 to enter the feed pipe 23 and then the inner cavity of the grouting cylinder 1. The operator holds the handle 10 and aligns the grouting head 9 with the tie bolt hole to be grouted. Air is expelled through the outlet of the L-shaped pipe 4 on the double-headed air pump 3, and gas is injected into the grouting cylinder 1 through the L-shaped pipe 4, pushing the piston block 15 forward and discharging the mortar from the grouting head 9, thus completing the grouting process. After grouting is complete, the gate valve 22 is closed. The air inlet of the double-headed air pump 3 at the air inlet pipe 5 is used to extract the gas from the grouting cylinder 1. The piston block 15 can be retracted. During the retraction of the piston block 15, the piston block 15 scrapes off the mortar remaining on the inner wall of the grouting cylinder 1. When the piston block 15 contacts the limiting plate 17, the mortar enters the collection trough 16. The air mixed with mortar is extracted by the air inlet end of the double-headed air pump 3 at the air inlet pipe 5. After internal compression, high-pressure gas is output from the exhaust end. The one-way valve 6 at the exhaust end ensures that the gas flows in one direction to prevent backflow from damaging the double-headed air pump 3. After the high-pressure gas enters the accumulator 12 through the one-way valve 6, the energy is stored in the accumulator 12. When the pressure of the accumulator 12 reaches the set upper limit, the double-headed air pump 3 stops working. When it is necessary to discharge the mortar, the pulse solenoid valve 13 is opened. The accumulator 12 releases high-pressure gas instantly to form a strong pulse, which generates a strong thrust in the air outlet pipe 14. The gas carries the mortar into the storage cylinder 21, and the mortar is reused.
