Description

Technical Field

[0001] The utility model belongs to the technical field of building construction pipeline fixing, and particularly relates to a fixing device for a concrete conveying elbow. Background Art

[0002] During the high-rise building construction process, a large amount of cast-in-place concrete construction is often involved. When using a concrete pump to convey concrete, due to the vibration of the concrete pump, the conveying pipe will shake and generate relatively large noise. Especially, the vibration at the elbow of the conveying pipe section (i.e., the first-floor pump pipe) is relatively serious. After fixing it, the occurrence of the above-mentioned adverse phenomena will be greatly reduced.

[0003] The general fixing methods are two types: fixing with concrete piers and fixing with steel pipe supports. The above two fixing methods have the following disadvantages. The former has a cumbersome production process and a long cycle for the concrete piers, and the overall is heavy and not easy to turnover. When the elbow vibrates, it is easy to have a hard collision with the concrete pier, resulting in a risk of wear at the elbow. While the latter, when fixed by the steel pipe support, due to the small contact area between the pipe body and the elbow, the fixing effect on the elbow is poor, and there is still vibration and noise. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a fixing device for a concrete conveying elbow, as described in detail below.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] The fixing device for a concrete conveying elbow provided by the utility model includes a rectangular outer frame and a conveying elbow. The rectangular outer frame includes a number of steel pipes and a number of pipe coupling joints. The pipe coupling joints are vertically and horizontally connected at the ends of the steel pipes to form the rectangular outer frame, and the conveying elbow is located inside the rectangular outer frame.

Detailed Embodiments

[0024] In order to make the purpose, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.

[0025] See Figures 1-4As shown in the figure, the present utility model provides a fixing device for a concrete conveying elbow, which includes a rectangular outer frame and a conveying elbow 14. The rectangular outer frame includes a number of steel pipes 1 and a number of pipe coupling joints 2. The pipe coupling joints 2 are located at the ends of the steel pipes 1 and are connected vertically and horizontally to form the rectangular outer frame. The conveying elbow 14 is located inside the rectangular outer frame. One side above the rectangular outer frame is fixedly connected with a top horizontal pipe 5 through a pipe coupling joint 2. One side below the rectangular outer frame is fixedly connected with a bottom horizontal pipe 8 through a pipe coupling joint 2. The bottom horizontal pipe 8 is located below the horizontal part of the conveying elbow 14. Arc-shaped support seats 12 are fixedly connected to both the top horizontal pipe 5 and the bottom horizontal pipe 8. The two arc-shaped support seats 12 are respectively in contact with the vertical part and the horizontal part of the conveying elbow 14. Arc-shaped cover plates 13 are provided on the opening sides of the two arc-shaped support seats 12. Bolt connecting pieces 3 for fixing the arc-shaped cover plates 13 are provided on both sides of the arc-shaped support seats 12;

[0026] An upper supporting belt 6 is provided on the lower side of the conveying elbow 14. The other side above the rectangular outer frame is fixedly connected with a connecting horizontal pipe 7 through a pipe coupling joint 2. A pulling and fixing piece for driving the upper supporting belt 6 to move upward is provided on the connecting horizontal pipe 7.

[0027] Refer to Figure 3 As shown in the figure, the bolt connecting piece 3 includes a nut 3a fixedly connected to the end of the arc-shaped support seat 12. A bolt 3b is threadedly connected to the nut 3a. A fixing sleeve 3c inserted with the bolt 3b is fixedly connected to the end of the arc-shaped cover plate 13. After the arc-shaped support seat 12 and the arc-shaped cover plate 13 are respectively located on both sides of the pipe body of the conveying elbow 14, the bolt 3b is inserted into the fixing sleeve 3c and the nut 3a at the same time and rotated to complete the preliminary fixing of the two to the conveying elbow 14.

[0028] Specifically, sponge pads are provided on the inner arc surfaces of the arc-shaped support seat 12 and the arc-shaped cover plate 13. The vibration of the conveying elbow 14 can be further buffered through the material characteristics of the sponge pads.

[0029] Refer to Figure 4 As shown in the figure, the pulling and fixing piece includes two rings 9 respectively sleeved on both sides of the connecting horizontal pipe 7. Fixing holes 11 are opened at the four corners of the upper supporting belt 6. One side of the ring 9 and the two fixing holes 11 on the same side are connected by two connecting ropes 10. An adjusting component 4 for driving the two rings 9 to approach or move away from each other is provided on the connecting horizontal pipe 7. After the upper supporting belt 6 is wrapped around the lower side of the conveying elbow 14, the ends of the multiple connecting ropes 10 are fixedly connected to the fixing holes 11 in the form of knots in sequence. At this time, the movement of the ring 9 can drive the upper ends of the connecting ropes 10 to move, thereby driving the upper supporting belt 6 to move upward to further reinforce the conveying elbow 14.

[0030] Furthermore, the end of the connecting rope 10 is fixedly connected to the fixing hole 11 by means of a knot. Fixing by means of a knot can achieve the effect of adjustable length of the connecting rope 10 in the area between the fixing hole 11 of the upper support belt 6 and the collar 9, so as to adjust in a timely manner according to the differences in the installation positions of the rectangular outer frames or the differences in the bending degrees of the conveying elbows 14.

[0031] Referring to Figure 2 As shown, the adjusting assembly 4 includes two ear plates 4a fixedly connected to the middle of the connecting cross-tube 7. The same bidirectional screw 4b is rotatably connected to the upper sides of the two ear plates 4a. Threaded sleeves 4c threadedly connected to the bidirectional screw 4b are fixedly connected to both collars 9, and the two threaded sleeves 4c are respectively located on both sides of the bidirectional screw 4b. By rotating the bidirectional screw 4b, the threaded sleeves 4c threadedly connected to both sides are driven to move away from each other. At this time, the two collars 9 also move away from each other on the connecting cross-tube 7. Under the pulling action of the upper ends of the two connecting ropes 10 moving away from each other, the upper support belt 6 is gradually tightened under the lower side of the conveying elbow 14, further stably reinforcing the conveying elbow 14.

[0032] Specifically, the middle cross-section of the bidirectional screw 4b is designed as a regular hexagon, and the part with the regular hexagon design is located between the two ear plates 4a, which is convenient for rotating the bidirectional screw 4b by tools such as a hexagon wrench, and can further increase the upward pulling force on the upper support belt 6 after manual rotation is impossible.

[0033] With the above structure, a number of steel pipes 1 are longitudinally and transversely spliced, and are fixedly connected by pipe hoop joints 2 at the end joints, so that a number of steel pipes 1 and a number of pipe hoop joints 2 are combined to form a rectangular outer frame. At this time, the conveying elbow 14 is located inside the rectangular outer frame. Subsequently, the top cross-tube 5, the connecting cross-tube 7 and the bottom cross-tube 8 are connected and installed on the rectangular outer frame through pipe hoop joints 2 in sequence. At this time, the arc-shaped brackets 12 on the top cross-tube 5 and the bottom cross-tube 8 are respectively abutted against the vertical part and the horizontal part of the conveying elbow 14. Then, the arc-shaped cover plate 13 is installed on the other side of the arc-shaped bracket 12 and fixed by bolt connectors 3. The two cooperate to surround and fix the conveying elbow 14. Then, the upper support belt 6 is wrapped around the lower side of the conveying elbow 14, and then the upper support belt 6 is pulled up by the pulling fastener until it is tightened, further fixing the conveying elbow 14.
