DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0015] The present embodiment includes a storage hopper 1, in which waterproof mortar is placed, and the holes of the tension bolts are sealed with the waterproof mortar. A conveying bin 2 is fixedly connected to the lower end surface of the storage hopper 1, and the conveying bin 2 is fixed on the bottom plate 4 of the flatbed trolley 3. Casters are provided at the bottom of the flatbed trolley 3, and a telescopic handle 22 is provided on one side to meet the needs of people of different heights to push the flatbed trolley 3. A vertical unloading channel 5 is provided downward in the middle of the upper surface of the conveying bin 2 of the present embodiment. The unloading channel 5 does not penetrate the conveying bin 2 downward, but is connected to the feeding channel 9 at the bottom. The upper end opening of the unloading channel 5 corresponds to the unloading port 6 of the storage hopper 1, and the waterproof mortar in the storage hopper 1 can enter the unloading channel 5 through the unloading port 6. The anti-backflow baffle A7 is rotatably connected to the inner wall of the upper end opening of the discharge channel 5. In this embodiment, a fixed shaft is installed on the inner wall of the discharge channel 5, and a sleeve is provided on the side of the anti-backflow baffle A7 close to the fixed shaft. The sleeve is sleeved on the fixed shaft and can rotate around the fixed shaft, thereby realizing the rotational connection of the anti-backflow baffle A7. Other existing structures that can realize the rotation function are all within the protection scope of the present invention, and no special restrictions are made on the rotational connection structure of the anti-backflow baffle A7. When the anti-backflow baffle A7 rotates upward to a horizontal state, it can block the upper end opening of the feeding channel 5. When the pressure in the feeding channel 5 increases, the anti-backflow baffle A7 can prevent the waterproof mortar from flowing back into the storage hopper 1. Therefore, the angle at which the anti-backflow baffle A7 can rotate downward should not be too large. For this purpose, a plurality of limit rods 8 are fixed on the inner wall of the feeding channel 5 below the anti-backflow baffle A7. The lower end of the limit rod 8 is fixed on the inner wall of the feeding channel 5. The limit rod 8 can be inclined upward to abut against the bottom surface of the anti-backflow baffle A7. , the anti-backflow baffle A7 is limited so that the anti-backflow baffle A7 cannot continue to rotate downward after contacting the limiting rod 8, thereby limiting the downward rotation angle of the anti-backflow baffle A7. In this embodiment, the limiting rod 8 is preferably used to limit the maximum rotation angle of the anti-backflow baffle A7 to 10-20°, that is, the anti-backflow baffle A7 can rotate downward from a horizontal state to a maximum of 10-20°, which can not only ensure that the waterproof mortar can flow down into the discharge channel 5, but also prevent the waterproof mortar from flowing back.

[0016] A horizontal feeding channel 9 is provided at the bottom of the conveying bin 2. The feeding channel 9 passes through the conveying bin 2 from front to back. The feeding channel 9 is located below the unloading channel 5, and the feeding channel 9 is connected to the unloading channel 5. A push rod 10 is provided in the feeding channel 9. In this embodiment, the push rod 10 is a cylindrical push rod 10, so the feeding channel 9 is also designed to be cylindrical, and the diameter of the push rod 10 is equal to the inner diameter of the feeding channel 9. The rear end of the push rod 10 is fixed to the telescopic rod of the telescopic mechanism 11. The telescopic mechanism 11 is installed on the bottom plate 4 of the flatbed car 3. The telescopic mechanism 11 is a device with a horizontal telescopic function. The front end of the telescopic rod of the telescopic mechanism 11 is fixed to the rear end of the push rod 10, which can drive the push rod 10 to slide horizontally forward and backward in the feeding channel 9. The telescopic mechanism 11 can be a hydraulic push rod or an electric telescopic rod, etc., and there is no special restriction here. It is preferred that the length of the push rod 10 is greater than the length of the feeding channel 9.

[0017] The anti-backflow baffle B12 is rotatably connected to the front outer wall of the feeding channel 9. The anti-backflow baffle B12 is located above the feeding channel 9. The anti-backflow baffle B12 droops naturally to block the front port of the feeding channel 9. Similarly, the anti-backflow baffle B12 is also rotatably connected via a fixed shaft and a sleeve. A fixed shaft is installed above the front port of the feeding channel 9. A sleeve is fixed on the anti-backflow baffle B12. The sleeve is sleeved on the fixed shaft and can rotate around the fixed shaft to achieve the rotational connection of the anti-backflow baffle B12. The present invention does not impose any special restrictions on the manner of rotating the connector. As long as the rotating connection structure can achieve the rotation function, it is within the protection scope of the present invention. The anti-backflow baffle B12 also has the function of blocking the backflow of the waterproof mortar.

[0018] A delivery pipe 13 is connected to the front end of the delivery channel 9 of the delivery bin 2. The delivery pipe 13 is a hose. The other end of the delivery pipe 13 is connected to the chamber of an injection gun 14. The injection gun 14 is used to inject waterproof mortar into the tension bolt holes. The anti-backflow baffle B12 is located in the delivery pipe 13. The inner diameter of the delivery pipe 13 is slightly larger than the diameter of the delivery channel 9.

[0019] The front end of the chamber of the injection gun 14 is open and the rear end is closed. A mechanism for pushing the waterproof mortar forward is provided in the chamber of the injection gun 14. An electric push rod 15 is fixed on the inner wall of the rear end of the chamber of the injection gun 14. A trowel plate 16 is fixed at the front end of the electric push rod 15. The trowel plate 16 is pushed by the electric push rod 15 to slide back and forth in the chamber. The diameter of the trowel plate 16 is equal to the inner diameter of the chamber of the injection gun 14. The inner diameter of the chamber of the injection gun 14 is equal to the aperture of the tension bolt hole. The inner diameter of the chamber of the injection gun 14 can also be slightly larger than the aperture of the tension bolt hole. For example, the inner diameter of the chamber of the injection gun 14 is 1-5mm larger than the aperture of the tension bolt hole. Preferably, the electric push rod 15 can push the trowel plate 16 to the front end position flush with the front end surface of the chamber of the injection gun 14, so that the trowel plate 16 can simultaneously smooth the outer end surface of the tension bolt hole.

[0020] A sealing ring 17 is fixed to the outer periphery of the front opening of the chamber of the injection gun 14. The sealing ring 17 is used to prevent the waterproof mortar injected into the tension bolt hole from running out. The sealing ring 17 can be a rubber ring. An overflow hole 18 is provided at the upper end of the sealing ring 17. The overflow hole 18 is a very thin disconnected seam opened at the upper end of the sealing ring 17. This disconnected seam allows excess waterproof mortar to flow out. As a further preferred solution, the amount of waterproof mortar pushed into the delivery pipe 13 by the push rod 10 at one time can be set to the amount of waterproof mortar required to fill the tension bolt hole. In this way, the amount of waterproof mortar entering the injection cavity each time is the amount of waterproof mortar required to fill the tension bolt hole. It can be pushed into the tension bolt hole by the trowel plate 16. In this way, the injection amount can be accurately controlled to avoid the waste of waterproof mortar.

[0021] In order to conveniently control the electric push rod 15 and the telescopic mechanism 11, the electric push rod switch 19 and the telescopic mechanism switch 20 can be arranged on the grip 21 of the injection gun 14, so that the worker can conveniently control the electric push rod 15 and the telescopic mechanism 11 during operation. The connection between the electric push rod switch 19 and the electric push rod 15 and the connection between the telescopic mechanism 11 and the telescopic mechanism switch 20 can be connected by wire or wirelessly.

[0022] When in use, pour the mixed waterproof mortar into the storage hopper 1. Due to gravity, the waterproof mortar will enter the discharge channel 5 through the discharge port 6 and then enter the feeding channel 9. First, open the telescopic mechanism 11 to allow the push rod 10 to repeatedly feed the waterproof mortar into the conveying pipe 13 until the waterproof mortar reaches the uppermost end of the conveying pipe 13. Then, align the front end of the chamber of the injection gun 14 with the tension bolt hole. At the same time, the sealing ring 17 surrounds the outside of the tension bolt hole and is close to the structural surface. Then, press the telescopic mechanism switch 20 again to allow the push rod 10 to push the waterproof mortar forward in the feeding channel 9. The corresponding amount of waterproof mortar that can fill the tension bolt hole is sent to the chamber of the injection gun 14. At this time, press the electric push rod switch 19 to push the trowel plate 16 forward to push the waterproof mortar into the tension bolt hole. At the same time, when the trowel plate 16 reaches the outer end face of the tension bolt hole, the waterproof mortar on the outer end face of the tension bolt hole is pressed and smoothed, and the filling and smoothing are completed at one time. Press the switch to return the electric push rod 15 and the telescopic mechanism 11 to their original positions, then move the injection gun 14 to the next tension bolt hole, and repeat the above operations to fill and smoothen. The grouting amount in the whole process is precisely controllable, and the filling and smoothing are completed in one step, which is both beautiful and ensures the construction quality.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
