Description

Technical Field

[0001] This application relates to the field of sewage pipe segment technology, specifically a prefabricated sewage pipe segment component mold. Background Technology

[0002] As an infrastructure component of urban drainage systems, the quality and production efficiency of sewage pipe segments have a significant impact on a city's sewage treatment capacity and construction costs.

[0003] Traditional molds often require manual tapping or mechanical devices for demolding, which is not only inefficient but also easily damages the tunnel lining segments. During the concrete pouring process, air bubbles and cavities are easily formed. Traditional molds lack an effective vibration mechanism, making it difficult to completely remove these defects. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a prefabricated sewage pipe segment component mold, which has advantages such as easy demolding and elimination of cavities, thus solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a prefabricated sewage pipe segment component mold, including a base frame, an arc-shaped mold above the base frame, and an arc-shaped push block slidably inserted into the inner bottom wall of the arc-shaped mold.

[0006] The upper surface of the base frame is fixedly connected to four limiting plates arranged in a matrix. Each limiting plate has a limiting rod horizontally slidably inserted inside. One end of each limiting rod is fixedly connected to one side of the arc-shaped mold. A spring is fixedly connected between each limiting plate and the arc-shaped mold. Rotating shafts are rotatably connected to the left and right ends of the upper surface of the base frame. Cams are fixedly connected to the top ends of the two rotating shafts. Each cam is in contact with the arc-shaped mold.

[0007] The above solution, through the cooperation of the arc-shaped pusher and the hydraulic rod, enables the workpiece to rise easily within the arc-shaped mold, thus greatly simplifying the demolding process. This not only improves demolding efficiency but also effectively avoids surface damage to the tunnel segments that may be caused by traditional hammering methods, ensuring the integrity of the finished tunnel segments. The combination design of the cam and spring provides an effective vibration mechanism for the arc-shaped mold. During the concrete pouring process, the vibration can promote the rapid discharge of air bubbles and cavities inside the concrete, thereby significantly improving the quality of the tunnel segments and reducing structural defects caused by air bubbles and cavities. The polishing treatment and Teflon coating on the inner wall of the arc-shaped mold not only reduce the friction between the concrete and the mold, making the demolding process smoother, but also improves the corrosion resistance and non-stick properties of the mold, extending its service life.

[0008] Further, the bottom of the arc-shaped mold is fixedly embedded with two hydraulic rods, and the output ends of the two hydraulic rods are fixedly connected with the bottoms of the arc-shaped push blocks close to them.

[0009] Through the above scheme, the up and down movement of the arc-shaped push block can be powered by the hydraulic rod.

[0010] Further, a set of moving wheels are installed at the bottom of the chassis.

[0011] Through the above scheme, the user can move the whole device conveniently by the moving wheels.

[0012] Further, two motors are installed at the bottom of the chassis, and the output ends of the two motors are fixedly connected with the bottom ends of the rotating shafts close to them.

[0013] Through the above scheme, the bottom of the chassis is provided with two motors, and the output ends of the two motors are fixedly connected with the bottom ends of the rotating shafts close to them.

[0014] Further, the inner wall of the arc-shaped mold is polished.

[0015] Through the above scheme, the polishing of the arc-shaped inner wall can reduce the friction between the concrete and the mold, make the demolding process smoother, and improve the smoothness of the finished product surface.

[0016] Further, the inner wall of the arc-shaped mold is coated with Teflon.

[0017] Through the above scheme, Teflon is a high molecular polymer material with high temperature resistance, corrosion resistance and excellent non-stick performance, which can effectively prevent the adhesion of concrete on the inner wall of the mold, thereby simplifying the demolding process.

[0018] Further, a control host is installed on one side of the arc-shaped mold.

[0019] Through the above scheme, the setting of the control host can realize the centralized control of the motor, hydraulic rod and other electrical components, so that the user can adjust the vibration frequency, push block rising speed and other parameters of the mold according to the production demand, improve the production efficiency and flexibility.

[0020] Further, a slot is formed at the bottom of the chassis, and the two hydraulic rods are located inside the slot.

[0021] Through the above scheme, the setting of the slot can avoid the collision between the hydraulic rod and the chassis during the vibration of the arc-shaped mold, and improve the safety of the whole device.

[0022] Compared with the prior art, the technical scheme of the present application has the following advantages:

[0023] The prefabricated sewage pipe piece component mold realizes easy lifting of the workpiece in the arc-shaped mold through cooperation of the arc-shaped push block and the hydraulic rod, thereby greatly simplifying the demolding process, improving the demolding efficiency, effectively avoiding possible surface damage of the pipe piece caused by the traditional knocking mode, ensuring the integrity of the pipe piece product, and providing an effective vibration mechanism for the arc-shaped mold through the combination design of the cam and the spring. In the concrete pouring process, the vibration can promote rapid discharge of bubbles and cavities in the concrete, thereby significantly improving the quality of the pipe piece and reducing structural defects caused by the bubbles and cavities. The polishing treatment and the Teflon coating of the inner wall of the arc-shaped mold not only reduce the friction between the concrete and the mold, make the demolding process smoother, but also improve the corrosion resistance and non-stick performance of the mold, prolong the service life of the mold.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3The bottom of the base frame 1 is provided with a notch 13, and the two hydraulic rods 9 are located inside the notch 13. Through the arrangement of the notch 13, the collision between the hydraulic rod 9 and the base frame 1 during the vibration of the arc-shaped mold 2 can be avoided, and the overall safety is improved.

[0035] The precast sewage pipe piece component mold in the embodiment realizes the easy lifting of the workpiece in the arc-shaped mold 2 through the cooperation of the arc-shaped push block 3 and the hydraulic rod 9, thereby greatly simplifying the demolding process. Not only the demolding efficiency is improved, but also the surface damage of the pipe piece caused by the traditional knocking method is effectively avoided, and the integrity of the pipe piece product is ensured.

Then, the motor 11 is started, the motor 11 drives the rotating shaft 7 to rotate, and then drives the cam 8 to rotate. The cam 8 contacts the arc-shaped mold 2, and by constantly changing the position of the contact point, the mold is vibrated. This vibration helps the bubbles and cavities inside the concrete to be discharged rapidly, improving the quality of the pipe piece. After the concrete solidifies, the hydraulic rod 9 is started, the output end of the hydraulic rod 9 is fixedly connected with the bottom of the arc-shaped push block 3, and the arc-shaped push block 3 is pushed up by the extension and contraction of the hydraulic rod 9. The upward movement of the arc-shaped push block 3 can drive the workpiece inside the mold to rise, thereby realizing easy demolding. The design of the moving wheels 10 at the bottom of the base frame 1 makes the entire mold move conveniently, which is convenient for operation at different work sites. The arrangement of the control host 12 realizes the centralized control of the electric elements such as the motor 11 and the hydraulic rod 9. The user can adjust the vibration frequency, the push block rising speed and other parameters of the mold according to the production demand, thereby improving the production efficiency and flexibility.
