Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe processing, in particular to a concrete pipe pouring device. Background Technique

[0002] Concrete is a composite material composed of cement, fine and coarse aggregates and water in appropriate proportions. It hardens in water and becomes hard and firm over time. When producing and pouring concrete pipes, the concrete mixture is usually poured into a mold, and through processes such as vibration and compaction, it is cured and formed into a pipe. After the concrete pipe is poured, in order to remove the pouring mold more smoothly, generally before pouring, a demoulding agent is sprayed on the inner surface of the mold. At present, when spraying the demoulding agent, it is usually carried out manually. Since the diameters and thicknesses of different pipes are inconsistent, the widths and depths of the pouring cavities between the inner and outer cylinders are also inconsistent. Manual spraying not only has low efficiency, but also the spraying uniformity is not easy to control, resulting in some concrete sticking to the formwork during demoulding later, affecting the pouring effect.

[0003] Based on the above situation, it is necessary to design a concrete pipe pouring device to solve the above problems. Summary of the Utility Model

Detailed implementation manner

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0019] Referring to Figures 1 - 3 As shown, a concrete pipe casting device includes a mold cavity 1, a connecting plate 2, a mounting bracket 5 and a rotating member 6. The mold cavity 1 is composed of an inner cylinder 11 and an outer cylinder 12 arranged coaxially. The outer wall of the inner cylinder 11 and the inner wall of the outer cylinder 12 form the mold cavity 1 for containing concrete casting material. For concrete pipes with different thicknesses, the diameters of the inner cylinder 11 and the outer cylinder 12 can be adjusted. Before pouring concrete into the mold cavity 1, in order to facilitate demolding after pouring, it is necessary to spray a demolding agent on the inner wall of the mold cavity 1. In order to improve the spraying uniformity and reduce the labor intensity, the present utility model has at least one mounting plate 3 movably connected to the connecting plate 2 through a sliding rod 21, and a mounting seat 4 is connected to the lower part of the mounting plate 3 through a first telescopic member 31. The first telescopic member 31 drives the mounting seat 4 to extend into the mold cavity 1. An mounting bracket 5 is movably connected to the mounting seat 4, and two mounting brackets 5 are symmetrically arranged on each mounting seat 4 with the middle of the mounting seat 4 as the center. A scraper 41 for cleaning debris on the inner wall of the mold cavity 1 and a spray head 42 for spraying a demolding agent on the inner wall of the mold cavity 1 are provided on the mounting seat 4, which can respectively process the outer surface of the inner cylinder 11 and the inside of the outer cylinder 12. And a rotating member 6 is provided above the connecting plate 2. The rotating member 6 can be a device such as a motor that can drive the mounting plate 3 to make a circular motion along the axis of the mold cavity 1, so as to drive the scraper 41 and the spray head 42 to make a circular motion along the mold cavity 1, and cooperate with the first telescopic member 31 to uniformly process the inner wall of the mold cavity 1.

[0020] Furthermore, as Figure 2As shown, in order to align the axis of the rotating member 6 with that of the mold cavity 1 so that the rotating member 6 can more stably drive the mounting plate 3 to perform circular motion along the mold cavity 1, a second telescopic member 7 is provided below the connecting plate 2. The movable end of the second telescopic member 7 is connected to a fixed seat 71. The axis of the second telescopic member 7 coincides with the axis of the rotating member 6. On both sides of the fixed seat 71, third telescopic members 72 are symmetrically arranged with respect to the middle of the fixed seat 71. When adjusting for mold cavities 1 with different planned diameters, the axis of the inner cylinder 11 may not coincide with the axis of the rotating member 6. At this time, the second telescopic member 7 moves downward, and the two third telescopic members 72 extend synchronously and in opposite directions, so that the two third telescopic members 72 are in contact with the inner wall of the inner cylinder 11. At this time, the straight line formed by the two third telescopic members 72 can be regarded as the inner diameter of the inner cylinder 11. Since the second telescopic member 7 is located between the two third telescopic members 72, it is convenient to adjust the position of the mold cavity 1 so that its axis coincides with the central axis of the rotating member 6.

[0021] Among them, as Figure 1 shown, it further includes a workbench 8. The mold cavity 1 is located on the workbench 8, and a fourth telescopic member 81 is provided at the top of the workbench 8. The movable end of the fourth telescopic member 81 is fixedly connected to the rotating member 6 through a fixing plate 82. The fourth telescopic member 81 can drive the rotating member 6 and the connecting plate 2 to move up and down. When it is necessary to take out the inner cylinder 11 and the outer cylinder 12 for demolding, the connecting plate 2 is moved upward to facilitate the removal of the inner cylinder 11 and the outer cylinder 12 from above.

[0022] Furthermore, a liquid storage box 9 for containing spraying liquid is provided on the mounting plate 3. A hose 91 is connected to the liquid storage box 9. The output end of the hose 91 is respectively communicated with two spray heads 42 on the mounting frame 5 through a three-way pipe 93. A water pump 92 is provided on the hose 91. The output directions of the two spray heads 42 on the mounting frame 5 are opposite, one facing the outer wall of the inner cylinder 11 and the other facing the inner wall of the outer cylinder 12. The water pump 92 transports the demolding agent in the liquid storage box 9 to the spray heads 42 and sprays it onto the inner wall of the mold cavity 1.

[0023] Furthermore, when it is necessary to adjust the position of the scraper 41 according to the specifications of the mold cavity 1, first, the position of the mounting frame 5 is adjusted so that the scraper 41 is in contact with the inner wall of the mold cavity 1. By rotating the setscrew 43 threadedly connected to the mounting seat 4, when the setscrew 43 abuts against the mounting frame 5, the mounting frame 5 is fixed inside the mounting seat 4.

[0024] Further, when producing concrete pipes with different diameters, that is, changing the diameter of the inner cylinder 11, the diameter of the mold cavity 1 changes synchronously. It is necessary to adjust the position of the first telescopic member 31. One side of the connecting plate 2 is rotatably connected with an adjusting screw 22. The adjusting screw 22 passes through the mounting plate 3 and is threadedly connected with the mounting plate 3. By rotating the adjusting screw 22, under the limiting and guiding action of the sliding rod 21, the mounting plate 3 can move along the axial extension direction of the adjusting screw 22, so that the first telescopic member 31 can be adjusted above the mold cavity 1 according to production needs, facilitating its insertion into the mold cavity 1. Preferably, the number of mounting plates 3 is two groups, which can perform spraying treatment work in the mold cavity 1 synchronously, improving work efficiency.

[0025] It should be noted that the first telescopic member 31, the second telescopic member 7, the third telescopic member 72, and the fourth telescopic member 81 can all be mechanisms capable of performing linear reciprocating motion, such as electric push rods or hydraulic rods.

[0026] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
