[0026] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions in the present utility model in conjunction with the drawings in the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0027] The following will describe Figures 1 - 4 a concrete box girder end-sealing device of the present utility model.

[0028] This embodiment provides a concrete box girder end-sealing device, including a base 1, a storage bin 2, and a discharge chute 3.

[0029] Among them, the storage bin 2 is arranged on the base 1, and a discharge port is arranged at the bottom of the storage bin 2; the discharge chute 3 is rotatably arranged on one side of the base 1 and is located below the discharge port. The discharge chute 3 can be switched between a first state and a second state. In the first state, the discharge chute 3 is inclined, and the first end of the discharge chute 3 is higher than the second end of the discharge chute 3; in the second state, the second end of the discharge chute 3 is higher than the first end of the discharge chute 3, and the first end of the discharge chute 3 can be adapted to the pouring port of the end-sealing formwork to convey the concrete in the storage bin 2 to the anchor hole at the end of the box girder through the discharge chute 3.

[0030] With such an arrangement, when performing the end-sealing operation on the concrete box girder structure, the storage bin 2 automatically supplies materials, reducing manual operation and improving the construction speed. The rotatable design of the discharge chute 3 makes it convenient to add materials to the storage bin 2 or perform other preparatory work when it is in the non-working first state; when it is in the second state, at this time, the concrete in the storage bin 2 can smoothly enter the discharge chute 3 through the discharge port under the action of gravity and finally flow to the anchor hole at the end of the box girder. By using the adaptation of the discharge chute 3 to the pouring port of the end-sealing formwork, it plays a guiding role, effectively avoiding the blockage and waste of concrete during the conveying process and improving the construction efficiency; and in the non-working state, when the concrete leaks from the discharge port, the discharge chute 3 can also effectively collect the concrete and prevent it from flowing to the ground and related working equipment.

[0031] Furthermore, it further includes a buffer box 4. The buffer box 4 is arranged between the discharge port and the discharge chute 3. The buffer box 4 includes a feed end and a discharge end. The feed end corresponds to the discharge port, and the discharge end corresponds to the discharge chute 3 and is located above the discharge chute 3.

[0032] With such an arrangement, the buffer box 4 can temporarily store the concrete flowing out of the storage bin 2, making the conveying process of the concrete smoother, avoiding the flow rate fluctuation caused by direct conveying, ensuring that the flow rate of the concrete entering the anchor hole through the discharge chute 3 is gentle and uniform. Even when there is a short-term flow rate fluctuation or blockage between the discharge port and the discharge chute 3, the discharge chute 3 can continuously receive the concrete, thereby reducing the interruption time of the end-sealing operation caused by waiting.

[0033] As Figure 1 shown, the buffer box 4 is connected to the side of the storage bin 2 corresponding to the discharge chute 3, and the discharge port is communicated with the inside of the storage bin 2; the discharge end of the buffer box 4 corresponds to the part between the rotation center of the discharge chute 3 and the first end, and the length of the part from the rotation center to the second end is greater than the length of the part from the rotation center to the first end, so that when not working, the discharge chute 3 is in an inclined state, and the height of the first end is greater than the height of the second end, which is convenient for the discharge chute 3 to effectively collect the concrete when the concrete leaks from the discharge port of the storage bin 2.

[0034] In some embodiments, a chamfer is provided at the end of the first end of the discharge chute 3, which is beneficial for docking the first end of the discharge chute 3 with the pouring port of the sealing end template.

[0035] In this embodiment, the width of the discharge chute 3 gradually decreases from the second end to the first end. With such a setting, as the flow path of the concrete gradually converges, it helps to reduce the resistance of the concrete during the flow process. The concrete is not likely to accumulate in the discharge chute 3 during the flow process, reducing the risk of blockage, enabling the concrete to flow out of the discharge chute 3 more smoothly, and helping to maintain the uniformity of the concrete during the flow process, avoiding the performance degradation of the concrete caused by long-term stay or poor flow.

[0036] In some embodiments, an adjusting rod 5 is detachably connected to the second end of the discharge chute 3. The length of the adjusting rod 5 is adjustable, and the adjusting rod 5 can be in contact with the bottom of the buffer box 4 when the discharge chute 3 is in the second state. With such a setting, when the discharge chute 3 is in the second state, the contact between the adjusting rod 5 and the bottom of the buffer box 4 is used to replace the contact between the second end of the discharge chute 3 and the bottom of the buffer box 4. By adjusting the length of the adjusting rod 5, the distance between the second end of the discharge chute 3 and the bottom of the buffer box 4 is changed, so as to change the inclination angle of the discharge chute 3 when transporting concrete, adjust the flow rate of the concrete towards the anchor hole, and improve the construction efficiency.

[0037] As Figure 3 shown, the adjusting rod 5 is connected to the second end of the discharge chute 3 by bolts. A plurality of connection holes can be provided along the axial direction of the adjusting rod 5. By connecting bolts to the connection holes at different positions, the length adjustment of the adjusting rod 5 can be realized, or adjusting rods 5 with different lengths can be selected according to actual needs to change the length of the adjusting rod 5.

[0038] Referring to Figure 1 And Figure 4 , in this embodiment, an installation frame is provided on the side of the base 1 facing the discharge chute 3. The discharge chute 3 is rotatably installed on the installation frame. For example, the installation frame includes a bottom plate 6, a rotating rod 7 and a pair of inclined struts 8. The bottom plate 6 is connected to the side of the base 1 facing the discharge chute 3. The pair of inclined struts 8 are arranged at intervals on both sides of the discharge chute 3. The upper end of each inclined strut 8 is connected to the storage box 2, and the lower end is connected to the bottom plate 6. The rotating rod 7 is arranged parallel to the bottom plate 6, and both ends of the rotating rod 7 are respectively connected to the pair of inclined struts 8. The discharge chute 3 is rotatably connected to the rotating rod 7, and in the first state, the discharge chute 3 can be in contact with the bottom of the discharge end of the buffer box 4.

[0039] Further, to increase the structural stability of the mounting bracket, at the connection between the diagonal brace 8 and the rotating rod 7, a first connecting rod and a second connecting rod are also provided. The first connecting rod is arranged parallel to the bottom plate 6, and its two ends are respectively connected to the outer side of the base 1 and the diagonal brace 8. The second connecting rod is arranged vertically, and its two ends are respectively connected to the bottom plate 6 and the diagonal brace 8.

[0040] In some embodiments, the bottom of the base 1 is provided with moving wheels (not shown in the figure) to facilitate the movement of the device.
