Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring, and specifically relates to a self-compacting concrete pouring device. Background Art

[0002] Self-compacting concrete is a type of construction concrete with high fluidity, good filling properties, and good stability. It can fill every corner of the formwork under its own weight without vibration and can pass through narrow spaces and complex reinforced structures.

[0003] However, during pouring, the traditional pouring device has a relatively simple structure, usually just a simple conveying pipe and pouring port. When pouring high-density reinforced structures, it takes a certain amount of time for concrete to flow and fill. During this time, the pouring device is constantly discharging material. When the discharge speed is higher than the concrete flow filling speed, it is very likely to cause concrete to gather under the pouring device, resulting in concrete accumulation and blockage, which not only affects the construction progress, but also may cause concrete waste.

[0004] In order to solve the above problems, this application proposes a self-compacting concrete pouring device. Utility Model Content

[0005] In view of the problems in the related art, the present invention proposes a self-compacting concrete pouring device to overcome the above technical problems existing in the existing related art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A self-compacting concrete pouring device comprises a pouring pipe, a mounting plate is provided at the bottom of the pouring pipe, the top of the mounting plate is fixedly connected to a fixing frame, the bottom of the fixing frame is fixedly connected to a guide column, the outer wall of the guide column is slidably connected to a moving block, the outer wall of the moving block is rotatably connected to a rotating rod, the end of the rotating rod away from the moving block is rotatably connected to a connecting rod, the end of the connecting rod away from the rotating rod is hinged to the bottom of the mounting plate, the top of the moving block is slidably connected to the guide rod, and the top of the moving block is fixedly connected to a return spring.

[0008] Preferably, a rubber ring is fixedly connected to the outer side wall of the connecting rod, a protective cover is fixedly connected to the top of the moving block, and the top of the protective cover is fixedly connected to the bottom of the fixing frame. By providing the protective cover and the rubber ring, the protective cover prevents concrete from entering the top of the moving block and prevents the return spring from getting stuck during use. The rubber ring facilitates adjustment of the concrete outlet to avoid accumulation.

[0009] Preferably, a fixing hole is provided on the outer wall of the movable block, a mounting seat is fixedly connected to the bottom of the fixing frame, and an adjustment rod is rotatably connected to the inner wall of the mounting seat. By providing the mounting seat and the adjustment rod, the position of the movable block can be restricted when not in use, thereby facilitating casting at a position with a smaller feed inlet.

[0010] Preferably, the end of the adjustment rod close to the fixing hole is fixedly connected with a clamping column, and the outer wall of the clamping column fits with the inner wall of the fixing hole. By setting the clamping column, the engagement between the adjustment rod and the fixing hole is improved, thereby improving the stability of the moving block and avoiding the position of the moving block from changing during use.

[0011] Preferably, the outer side wall of the mounting plate is fixedly connected to an extension frame, the inner side wall of the extension frame is rotatably connected to a connecting block, the bottom of the connecting block is fixedly connected to an arc-shaped support plate, and the inner side wall of the arc-shaped support plate fits with the outer side wall of the adjusting rod. By setting the extension frame, the connecting block and the arc-shaped support plate, it is convenient to fix the adjusting rod so as to limit the position of the moving block.

[0012] Preferably, a push rod is fixedly connected to the top of the connecting block, and the push rod and the arc-shaped support plate are located on the same vertical line. By providing the push rod, it is convenient for the operator to adjust the position of the connecting block.

[0013] To sum up, the technical effects and advantages of the utility model are as follows: the self-compacting concrete pouring device, through the coordinated use of the mounting plate, the fixing frame, the guide column, the moving block, the rotating rod, the connecting rod, the guide rod, and the return spring, facilitates the movement of the concrete accumulated at the bottom of the pouring pipe, thereby preventing the concrete from accumulating at the bottom of the pouring pipe during pouring, and further preventing the concrete from flowing too slowly due to accumulation, thereby affecting the efficiency of concrete pouring.

[0014] By using the moving block, rotating rod, connecting rod, protective cover and rubber ring in coordination, concrete can be prevented from entering the top of the moving block during pouring, thereby preventing the concrete from causing the reset spring to be stuck. In addition, by using the rotating rod, connecting rod and rubber ring in coordination, the size of the pouring port can be easily adjusted, thereby improving the accuracy of pouring.

[0024] Reference Figure 2 and Figure 3 The outer wall of the connecting rod 7 is fixedly connected with a rubber ring 11. The material of the rubber ring 11 is elastic rubber material. When the six connecting rods 7 expand in the direction away from the moving block 5, the six connecting rods 7 stretch the rubber ring 11, thereby expanding the diameter of the concrete discharge port, thereby improving the discharge efficiency, and facilitating the operator to adjust the flow rate of the concrete according to the size of the pouring port. The top of the moving block 5 is fixedly connected with a protective cover 10. The protective cover 10 is an extendable telescopic cover. The top of the protective cover 10 is fixedly connected to the bottom of the fixed frame 3 to prevent concrete from being retained on the top of the moving block 5 during the pouring process, thereby preventing the solidified concrete from blocking the return spring 9.

[0025] Reference Figure 4 The outer wall of the moving block 5 is provided with a fixing hole 12, and there are two fixing holes 12. The two fixing holes 12 are symmetrically distributed with the central axis plane of the moving block 5. The bottom of the fixing frame 3 is fixedly connected with a mounting seat 16, and the inner side wall of the mounting seat 16 is rotatably connected with an adjustment rod 17. There are two mounting seats 16 and two adjustment rods 17. The two mounting seats 16 and the adjustment rods 17 correspond to the positions of the two fixing holes 12 respectively. When not in use, the position of the moving block 5 is restricted by the two adjustment rods 17 to prevent the moving block 5 from sliding toward the bottom direction of the guide column 4 when not in use.

[0026] Reference Figure 1 and Figure 4 The adjusting rod 17 is fixedly connected to one end of the fixing hole 12 with a clamping column 18. Two clamping columns 18 are provided, and the outer walls of the two clamping columns 18 fit with the inner walls of the fixing hole 12. The two clamping columns 18 are located inside the two fixing holes 12. The two clamping columns 18 facilitate improving the clamping stability of the two adjusting rods 17 and the two fixing holes 12.

[0027] With reference to Figure 1 and Figure 4 , the outer side wall of the mounting plate 2 is fixedly connected with an extension frame 13, the extension frame 13 is provided with two, the two extension frames 13 are distributed in the central axis of the mounting plate 2 symmetrically, the inner side wall of the two extension frames 13 is rotatably connected with a connecting block 14 respectively, the bottom of the two connecting blocks 14 is fixedly connected with an arc-shaped support plate 15 respectively, the inner side wall of the two arc-shaped support plates 15 is matched with the outer side wall of the adjusting rod 17 respectively, when not in use, rotate the two connecting blocks 14, rotate the position of the two arc-shaped support plates 15 to the top of the two adjusting rods 17, and the bottom outer side wall of the two arc-shaped support plates 15 is matched with the top outer side wall of the two adjusting rods 17 respectively, at this time, the position of the two adjusting rods 17 is limited by the two arc-shaped support plates 15, avoiding the position of the two adjusting rods 17 changing when not in use.

[0028] With reference to Figure 1 and Figure 4 , the top of the connecting block 14 is fixedly connected with a push rod 19, the push rod 19 is provided with two, the two push rods 19 are located at the top of the two connecting blocks 14 respectively, and the two push rods 19 are located on the same vertical line with the two arc-shaped support plates 15 respectively, the two push rods 19 lengthen the force arm of the two arc-shaped support plates 15, which facilitates reducing the effort spent by the operator when rotating the arc-shaped support plate 15.

[0029] Working principle: when pouring concrete, the moving block 5 is affected by the force generated by the falling of the concrete and moves away from the mounting plate 2, at this time, the rotating rod 6 connected with the moving block 5 moves away from the mounting plate 2 synchronously, at this time, the moving block 5 stretches the two return springs 9, because the end of the rotating rod 6 away from the moving block 5 is rotatably connected with the connecting rod 7, and the end of the connecting rod 7 away from the rotating rod 6 is hingedly connected with the bottom of the mounting plate 2, so when the moving block 5 moves away from the mounting plate 2, it will push the connecting rod 7 away from the moving block 5, so that the six connecting rods 7 expand outward in a circular shape, because the flow rate of the concrete is different, the moving block 5 moves back and forth along the guide column 4 under the action of the two return springs 9, thereby driving the rotating rod 6 and the connecting rod 7 to expand and contract back and forth, and then stirring the concrete, thereby avoiding the accumulation of concrete at the bottom of the pouring pipe 1, thereby avoiding affecting the flow rate of the concrete, improving the pouring efficiency of the concrete, and shielding the concrete with the protective cover 10 during pouring, avoiding the concrete stagnating on the top of the moving block 5 during pouring, thereby avoiding the agglomerated concrete causing the return spring 9 to be blocked.
