Description

Technical Field

[0001] The present application relates to the technical field of construction equipment, and more specifically, to a device for blocking a material conveying pipe of a concrete placing boom. Background Art

[0002] A concrete placing boom is a widely used construction machinery, mainly used for conveying the pumped concrete into the formwork of the component to be poured through a pipeline.

[0003] During the use of the existing concrete placing boom, after the material conveying pipe for conveying concrete is used up, it needs to be disassembled from the placing system. However, there is still some uncast concrete remaining in the material conveying pipe. When the material conveying pipe is disassembled, the residual concrete will leak during the movement of the placing boom after the concrete is poured, resulting in waste.

[0004] To solve the above problems, the present application provides a device for blocking a material conveying pipe of a concrete placing boom. Utility Model Content

[0005] The present application provides the following technical solution: A device for blocking a material conveying pipe of a concrete placing boom, including a main body of the material conveying pipe, a fixed frame is fixedly connected to the front end of the main body of the material conveying pipe, a blocking plate is slidably connected to the inner side of the fixed frame, a handle is fixedly connected to the left end face of the blocking plate, a bidirectional lead screw is rotatably connected to the inner side of the handle, two moving plates are symmetrically and slidably connected to the surface of the blocking plate, a limiting rod is fixedly connected to the opposite side of each of the two moving plates, two limiting grooves two and two limiting grooves one are symmetrically formed in the inner side of the fixed frame, and the end of the limiting rod away from the moving plate extends into the interior of the limiting groove two.

[0006] Through the above technical solution, by rotating the handle to screw the bidirectional lead screw, the limiting rod is moved out of the interior of the limiting groove two, and then the handle is lifted to drive the blocking plate to move, so that the right end of the blocking plate abuts against the inner wall of the semi-circular plate. At this time, the blocking plate blocks the port of the main body of the material conveying pipe, and the limiting rod corresponds to the limiting groove one. Then, the handle is rotated in the reverse direction to drive the bidirectional lead screw to rotate, so that the limiting rod is inserted into the interior of the limiting groove one, completing the limiting and fixing of the blocking plate, and thus completing the blocking of the port of the main body of the material conveying pipe, avoiding the leakage of the concrete material and resulting in waste.

[0007] Further, a semi-circular plate is provided at the right end of the fixed frame, and the semi-circular plate is fixedly connected to the front end of the main body of the material conveying pipe.

[0008] Through the above technical solution, the semi-circular plate can play a role in blocking the blocking plate.

[0009] Further, both the grip and the fixing frame are arranged in a "U"-shaped structure, and the bottom end of the bidirectional lead screw extends to the outside of the grip and is fixedly connected with a rotating handle.

[0010] Through the above technical solution, the rotating handle is used to conveniently screw the bidirectional lead screw.

[0011] Further, two sliding grooves are symmetrically formed on the grip, and the limiting rod is slidably inserted into the interior of the sliding grooves.

[0012] Through the above technical solution, the sliding grooves can limit the limiting rod and improve the stability of the limiting rod during movement.

[0013] Further, two sliding plates are symmetrically and fixedly connected to the inner side of the fixing frame, and the blocking plate is slidably sleeved on the outside of the two sliding plates.

[0014] Through the above technical solution, the sliding plates can limit the blocking plate, and the blocking plate moves on the outside of the two sliding plates, improving the stability of the blocking plate during movement.

[0015] Further, sliding grooves are formed on the sliding plates, and the limiting rod is slidably connected to the interior of the sliding grooves.

[0016] Through the above technical solution, the sliding grooves can further limit the limiting rod. At the same time, when the grip is used to drive the blocking plate to move, the limiting rod moves with the blocking plate inside the sliding grooves.

[0017] Further, one end of the blocking plate is arranged in a rounded corner structure, while the other end of the blocking plate is arranged in a flat surface.

[0018] In summary, the present application includes the following beneficial technical effects:

[0019] The rotating handle is used to screw the bidirectional lead screw, so that the limiting rod is moved out of the interior of the second limiting groove. Then, the grip is lifted by hand to drive the blocking plate to move, so that the right end of the blocking plate abuts against the inner wall of the semi-circular plate. At this time, the blocking plate blocks the port of the material conveying pipe body, and the limiting rod corresponds to the first limiting groove. Then, the rotating handle is reversely screwed to drive the bidirectional lead screw to rotate, so that the limiting rod is inserted into the interior of the first limiting groove, completing the limiting and fixing of the blocking plate, and thus completing the blocking of the port of the material conveying pipe body, avoiding the leakage of concrete material and causing waste.

[0028] The embodiment of the present application discloses a device for blocking the material conveying pipe of a concrete placing boom. Please refer to Figure 1 , Figure 2 and Figure 3, including the main body 1 of the material conveying pipe, a fixing frame 2 is fixedly connected to the front end of the main body 1 of the material conveying pipe, a blocking plate 4 is slidably connected to the inner side of the fixing frame 2, one end of the blocking plate 4 is arranged in a rounded corner structure, while the other end of the blocking plate 4 is arranged in a flat surface, a handle 9 is fixedly connected to the left end surface of the blocking plate 4, a bidirectional lead screw 10 is rotatably connected to the inner side of the handle 9, two moving plates 11 are symmetrically and slidably connected to the surface of the blocking plate 4, a limiting rod 8 is fixedly connected to the opposite sides of the two moving plates 11, and two limiting grooves II 6 and two limiting grooves I 3 are symmetrically formed in the inner side of the fixing frame 2;

[0029] One end of the limiting rod 8 away from the moving plate 11 extends into the interior of the limiting groove II 6. By turning the handle 14 to screw the bidirectional lead screw 10, the rotation of the bidirectional lead screw 10 drives the two moving plates 11 to move relatively. The relative movement of the two moving plates 11 respectively drives the two limiting rods 8 to move relatively, so that the limiting rod 8 moves out of the interior of the limiting groove II 6. Then, hold the handle 9 by hand to drive the blocking plate 4 to move, so that the right end of the blocking plate 4 abuts against the inner wall of the semi-circular plate 13. At this time, the blocking plate 4 blocks the port of the main body 1 of the material conveying pipe, and the limiting rod 8 corresponds to the limiting groove I 3. Then, reverse-rotate the handle 14 to drive the bidirectional lead screw 10 to rotate, so that the limiting rod 8 is inserted into the interior of the limiting groove I 3 to complete the limiting and fixing of the blocking plate 4.

[0030] Please refer to Figure 1 , a semi-circular plate 13 is arranged at the right end of the fixing frame 2. The semi-circular plate 13 can play a role in blocking the blocking plate 4. The surface of the semi-circular plate 13 and the surface of the fixing frame 2 are on the same horizontal plane. The semi-circular plate 13 is fixedly connected to the front end of the main body 1 of the material conveying pipe. Both the handle 9 and the fixing frame 2 are arranged in a "U"-shaped structure. The bottom end of the bidirectional lead screw 10 extends to the outside of the handle 9 and is fixedly connected to a rotating handle 14. The rotating handle 14 is used to conveniently screw the bidirectional lead screw 10.

[0031] Please refer to Figure 1 and Figure 2 , two sliding grooves 12 are symmetrically formed in the handle 9. The limiting rod 8 is slidably inserted into the interior of the sliding grooves 12. The sliding grooves 12 can limit the limiting rod 8 and improve the stability of the limiting rod 8 during movement. Two sliding plates 7 are symmetrically and fixedly connected to the inner side of the fixing frame 2. The blocking plate 4 is slidably sleeved on the outside of the two sliding plates 7. The sliding plates 7 can limit the blocking plate 4. When the blocking plate 4 moves, it moves on the outside of the two sliding plates 7, improving the stability of the blocking plate 4 during movement.

[0032] Please refer to Figure 1 and Figure 2 , a sliding groove 5 is formed in the sliding plate 7. The limiting rod 8 is slidably connected to the interior of the sliding groove 5. The sliding groove 5 can further limit the limiting rod 8. At the same time, when the handle 9 is used to drive the blocking plate 4 to move, the limiting rod 8 moves in the interior of the sliding groove 5 along with the blocking plate 4.

[0033] The implementation principle of the embodiment of this application is as follows: When it is necessary to block the main body 1 of the material conveying pipe, the two-way lead screw 10 is screwed by rotating the handle 14. The rotation of the two-way lead screw 10 drives the two moving plates 11 to move relatively. The relative movement of the two moving plates 11 respectively drives the two limiting rods 8 to move relatively, so that the limiting rods 8 are moved out of the inside of the second limiting groove 6. Then, the handle 9 is held by hand to drive the blocking plate 4 to move, so that the right end of the blocking plate 4 abuts against the inner wall of the semi-circular plate 13. At this time, the blocking plate 4 blocks the port of the main body 1 of the material conveying pipe, and the limiting rod 8 corresponds to the first limiting groove 3. Then, the handle 14 is rotated in the reverse direction to drive the two-way lead screw 10 to rotate, so that the limiting rod 8 is inserted into the inside of the first limiting groove 3, completing the limit fixation of the blocking plate 4, and thus completing the port blocking of the main body 1 of the material conveying pipe, avoiding the leakage of concrete materials and causing waste.

[0034] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
