Description

Technical Field

[0001] This utility model relates to the field of core mold vibration tube making technology, and in particular to a core mold vibration tube making inner wall polishing device. Background Technology

[0002] The inner wall finishing process of the mandrel vibration pipe forming is a key step in improving the surface quality of the concrete pipe. After the mandrel (vibrator) is removed, when the concrete in the pipe is in its initial setting state (it can self-stabilize and form but has not yet fully hardened), tools such as scrapers and grinding heads are used to apply moderate and controllable pressure to the inner wall of the pipe and perform scraping or grinding movements. This process aims to remove burrs, laitance, joint marks, and minor unevenness generated during demolding, and fill surface pores, thereby significantly improving the smoothness, flatness, and dimensional accuracy of the inner wall, providing better hydraulic performance and interface quality for subsequent pipe laying.

[0003] In the prior art, multiple sets of scrapers are usually set inside the reinforced concrete drainage pipe. A spring is fixedly installed on the side of each scraper to apply pressure to the scraper. The spring pushes the scraper against the inside of the reinforced concrete pipe and rotates the scrapers synchronously along the pipe axis, thereby removing the burrs on the inner wall of the pipe.

[0004] However, in actual use, reinforced concrete pipes may be softer when the core is first extracted, requiring gentler pressure; after they harden somewhat, the pressure needs to be increased slightly. Existing equipment makes it difficult to adjust the pressure on the scraper. During the inner wall finishing process, excessive pressure applied by the scraper to the pipe wall can damage the pipe, while insufficient pressure can weaken the finishing effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the hardness of reinforced concrete changes over time after core mold vibration pipe making, while the pressure applied by the scraper to the inner wall of the pipe remains constant, which reduces the finishing effect. Therefore, this invention proposes a core mold vibration pipe making inner wall finishing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The device for polishing the inner wall of a mandrel vibratory tube is designed, including a cross plate with a rotating shaft fixedly connected to its center. It also includes a pressure regulating assembly comprising several rotating shafts rotatably connected to the cross plate. A connecting plate is fixedly connected to the end of each rotating shaft, and a scraper is fixedly connected to the side of the connecting plate. An arc-shaped spring is fixedly connected to the side of the scraper, and an adjusting plate is fixedly connected to the end of the arc-shaped spring. The adjusting plate and the cross plate are in sliding engagement.

[0008] Preferably, a hinge seat is fixedly connected to the surface of the adjusting plate, a hinge rod is hinged to the hinge seat, a square plate is provided between the hinge rods, and the hinge rods and the square plate are hinged to each other.

[0009] Preferably, a U-shaped frame is fixedly connected to the surface of the cross plate, and a lead screw is rotatably connected between the U-shaped frame and the cross plate, and the lead screw is threadedly connected to the square plate.

[0010] Preferably, the lead screw is located at the center of the square plate.

[0011] Preferably, a handwheel is fixedly connected to the end of the lead screw, and the handwheel is made of rubber.

[0012] Preferably, the arc-shaped spring is a stainless steel spring.

[0013] Preferably, the cross plate has a plurality of sliding grooves, and a slider is slidably connected in the sliding grooves. The slider is fixedly connected to the corresponding adjustment plate.

[0014] Preferably, the cross plate and the U-shaped frame are in a sliding fit.

[0015] The beneficial effects of the core mold vibration tube inner wall finishing device proposed in this utility model are as follows: When using this utility model, rotating the handwheel drives the lead screw to rotate, and the square plate slides up and down along the U-shaped frame, thereby adjusting the position of each adjustment plate. The change in the position of the adjustment plate can adjust the pressure of the arc spring on the scraper, thereby adjusting the pressure of the scraper on the reinforced concrete during edge trimming and improving the finishing effect on the inner wall of the tube.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-5 This utility model is a core mold vibration tube inner wall polishing device, including a cross plate 1, with a rotating shaft 14 fixedly connected to the center of the cross plate 1. The feature is that it also includes a pressure adjustment component, which includes several rotating shafts 2, the rotating shafts 2 being rotatably connected to the cross plate 1, a connecting plate 3 being fixedly connected to the end of the rotating shaft 2, a scraper 4 being fixedly connected to the side of the connecting plate 3, an arc spring 8 being fixedly connected to the side of the scraper 4, and an adjustment plate 7 being fixedly connected to the end of the arc spring 8. The adjustment plate 7 and the cross plate 1 are in sliding fit.

[0026] The operation process of this embodiment is as follows: The rotating shaft 14 is set at the axial position of the formed concrete drainage pipe. It can be driven manually or connected to an external motor. The motor drives the rotating shaft 14 to rotate. The rotating shaft 14 is located at the center of the cross plate 1. That is, when the rotating shaft 14 rotates, it can drive the cross plate 1 to rotate at the axial position of the inner wall of the pipe.

[0027] The user moves each scraper 4, compresses the arc spring 8, and inserts the device into the concrete pipe. The arc spring 8 pushes each scraper 4 tightly against the inner wall of the pipe. During use, the cross plate 1 rotates, and the rotational force drives each scraper 4 to rotate along the inner wall of the pipe. When the scraper 4 rotates, the arc spring 8 pushes it to fit against the inner wall of the pipe and applies a certain pressure, thereby scraping off the burrs on the inner wall of the pipe. The pipe formed by the core mold vibration is relatively soft in the early stage and gradually hardens after a period of time after forming. The pressure applied by the arc spring 8 to the scraper 4 remains consistent. Therefore, the position of the adjusting plate 7 on the cross plate 1 can be moved according to the hardness of the reinforced concrete. Since the adjusting plate 7 is fixedly connected to the arc spring 8, the movement of the adjusting plate 7 can increase or decrease the pressure of the arc spring 8 on the scraper 4. Thus, during use, the position of the adjusting plate 7 can be adjusted according to the hardness of the reinforced concrete drainage pipe to change the pressure of the arc spring 8 on the scraper 4, which can avoid the weakening of the finishing effect caused by the scraper 4 applying too much or too little pressure to the inner wall of the pipe.

[0028] Example 2

[0029] In practical use, each scraper 4 needs to apply consistent pressure to the inner wall of the pipe. During adjustment, it is difficult to adjust the positions of each adjusting plate 7 synchronously. Therefore, please refer to [the relevant documentation / reference needed]. Figure 2-5 Based on the first specific embodiment, a hinge seat 15 is fixedly connected to the surface of the adjusting plate 7, and a hinge rod 12 is hinged to the hinge seat 15. A square plate 11 is arranged between the hinge rods 12, and the hinge rods 12 and the square plate 11 are hinged to each other. A U-shaped frame 9 is fixedly connected to the surface of the cross plate 1, and a lead screw 10 is rotatably connected between the U-shaped frame 9 and the cross plate 1. The lead screw 10 is threadedly connected to the square plate 11. The lead screw 10 is located at the center of the square plate, and a handwheel 13 is fixedly connected to the end of the lead screw 10. The handwheel 13 is made of rubber, and the arc spring 8 is a stainless steel spring. Several sliding grooves 5 are opened in the cross plate 1, and sliders 6 are slidably connected in the sliding grooves 5. The sliders 6 are fixedly connected to the corresponding adjusting plate 7, and the cross plate 1 and the U-shaped frame 9 are slidably engaged.

[0030] The operation process of this embodiment is as follows: When adjusting the pressure of the scraper 4 on the inner wall of the pipe, turn the handwheel 13. The rotation of the handwheel 13 drives the screw 10 to rotate. Since the square plate 11 and the U-shaped frame 9 are in sliding fit, the square plate 11 moves up and down along the U-shaped frame 9. The two ends of each hinge rod 12 are respectively hinged to the square plate 11 and the hinge seat 15. At this time, the movement of the square plate 11 causes each hinge rod 12 to be displaced. Since the adjusting plate 7 and the slider 6 are fixed, and the slider 6 can only move in the slide groove 5, the movement of the hinge rod 12 can drive the adjusting plate 7 to move linearly along its corresponding slide groove 5, thereby realizing the rapid adjustment of the position of each adjusting plate 7. It can synchronously adjust the pressure of each scraper 4 on the inner wall of the reinforced concrete pipe, further improving the practicality of the device.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
