Description

Technical Field

[0001] This application belongs to the field of cement product processing equipment, and more specifically, it relates to a production apparatus for plastic drainage pipe fittings and cement shells for pipes. Background Technology

[0002] In the application of cement mortar, vibration is required to liquefy the mortar and effectively improve its density. Existing technologies often employ vibratory compactors for cement mortar vibration. For example, Chinese Patent Publication No. CN111962875A discloses a cement mortar vibrator comprising a slide plate, a rotating support, a first rotating drive mechanism, a mounting frame, a connecting pipe, a second rotating drive mechanism, a lifting mechanism, a vibratory rod, and a drill bit. The slide plate, in its working state, is placed on the surface of the concrete being constructed and has through holes for the vibratory rod and drill bit to pass through. The rotating support is rotatably mounted on the slide plate. The first rotating drive mechanism is mounted on the slide plate. The mounting frame is mounted on the top of the rotating support. The connecting pipe is clearance-fitted to the mounting frame. The second rotating drive mechanism is mounted on the mounting frame, with its output end clearance-fitted to the connecting pipe along the axial direction and fixedly connected to the connecting pipe circumferentially. The lifting mechanism is mounted on the mounting frame, with its working end fixedly connected to the connecting pipe. The vibratory rod is mounted at the bottom of the connecting pipe, and the drill bit is mounted at the bottom of the vibratory rod.

[0003] However, for plastic drainage pipe fittings or plastic drainage pipes covered with a cement shell, during their production process, it is impossible to use a vibrator to effectively vibrate the cement mortar inside the mold, or the vibration is too cumbersome due to the limitations of the mold. As a result, the cement mortar inside the mold cannot be effectively vibrated and liquefied, which reduces the quality of the cement shell produced by the mold. Summary of the Invention

[0004] The purpose of this application is to provide a production apparatus for plastic drainage pipe fittings and cement shells, which can ensure the density of cement mortar in the mold, improve the strength and service life of the cement shell, and thus help improve the quality of the produced cement shell.

[0005] To achieve the above objectives, this application employs the following technical solution: The production apparatus for plastic drainage pipe fittings and cement shells of pipes described in this application includes a concrete foundation, on which a frame is installed. Several vibration springs are distributed on the frame, and the frame is connected to a vibration table via the vibration springs. Several molds are connected to the vibration table via anti-loosening fasteners, and each mold is connected to a cement mortar conveying pipe. A housing is also located in the middle of the vibration table, and a vibration motor is installed inside the housing. Driven by the vibration motor, the vibration table moves relative to the frame. The vibration springs are connected to the frame via screws, nuts, and washers, and the screws and nuts are connected using an anti-loosening threaded structure. The molds are arranged symmetrically on both sides of the vibration table, with several molds on the same side of the vibration table arranged in a matrix and symmetrically positioned on the vibration table. The housing is located in the middle of the vibration table.

[0006] Preferably, as one of the technical solutions of this application, a rubber block is provided at the connection position between the concrete foundation and the frame.

[0007] Preferably, as one of the technical solutions of this application, the top of the mold is provided with a grouting hole, which is connected to a cement mortar conveying pipeline.

[0008] Preferably, as one of the technical solutions of this application, the cement mortar conveying pipe is a rubber hose with a wear-resistant and smooth inner wall, and the cement mortar conveying pipe is connected to the cement mortar grouting equipment at the end away from the mold.

[0009] Preferably, as one of the technical solutions of this application, the vibration table is an aluminum alloy plate.

[0010] Preferably, as one of the technical solutions of this application, the vibration table is connected to a baffle by anti-loosening fasteners. The baffle is located at both ends of the mold and blocks the openings at both ends of the mold. A plastic drain pipe is coaxially arranged inside the mold. A sizing collar is provided at one or both ends of the plastic drain pipe at the position where it passes through the baffle. The sizing collar blocks the openings at both ends of the mold. The mold has a grouting hole and a venting hole.

[0011] Preferably, as one of the technical solutions of this application, the mold is provided with a plurality of support plates in the length direction, the bottom end of the support plate is connected to the vibration table, and the top end of the support plate is in contact with the mold.

[0012] Compared with the prior art, the beneficial effects of this application are: 1. This application, by directly setting a vibration motor on the vibration table, not only facilitates the direct transmission of vibration but also reduces the impact on the stability of the frame itself. Several molds are installed on the vibration table, which not only enables the disassembly of the molds from the frame but also ensures the compactness of the cement mortar filling inside the molds, thereby improving the strength and service life of the cement shell. The required molds should be symmetrically set and evenly distributed on the vibration table to ensure the self-balance of the vibration table during the vibration process.

[0013] 2. In this application, a rubber block is fitted on the bolt connection assembly between the frame and the concrete foundation. The rubber block can reduce the impact of the frame vibration on the concrete foundation through its limited deformation. When wear occurs, it can be visually observed and is easy to replace, resulting in low maintenance costs in the later stage.

[0014] 3. During the production of the cement shell covering the plastic drainage pipe, sizing collars and baffles are needed to seal the mold. Furthermore, during the grouting process, vent holes need to be opened in the mold to ensure stable grout injection. Since the plastic drainage pipe extends a certain distance, several support plates need to be distributed along the length of the mold that extends with it. Attached Figure Description

[0026] The structure and connection relationships of the remaining parts are the same as those described in any of the foregoing embodiments, and will not be repeated here to avoid unnecessary detail.

[0027] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0028] In this application, the vibration table 1 is made of aluminum alloy, which can ensure the strength of the vibration table itself and meet the requirements of vibration transmission.

[0029] In this application, the molds 2 are distributed on both sides of the vibration table 1. The molds 2 on both sides of the vibration table 1 are symmetrically distributed, and the molds 2 on each side of the vibration table 1 are arranged in a matrix and symmetrically set on the vibration table 1 to meet the problem of vibration balance of the vibration table 1 during vibration.

[0030] The mold 2 and the vibration table 1 are connected by anti-loosening fasteners to meet the requirements of disassembly. At the same time, during daily maintenance, during each use interval or routine inspection, maintenance personnel should check the connection stability and looseness of bolts and fasteners to ensure the overall stability of the vibration equipment. The specific selection of anti-loosening threads can be made by those skilled in the art according to their needs.

[0031] In this application, the mold 2 is connected to the cement mortar conveying pipe 12 through the grouting hole 13. The grouting hole 13 is located at the top of the mold 2. The cement mortar conveying pipe 12 is a rubber hose. In order to meet the conveying requirements of cement mortar, the inner wall of the cement mortar conveying pipe 12 should be smooth and wear-resistant to improve the conveying efficiency of cement mortar and its service life.

[0032] In this application, the vibration motor 5 transmits vibration to the vibration table 1 through the housing 6, thereby vibrating the cement mortar inside the mold 2 through the vibration table 1, which improves the density of the cement mortar.

[0033] In this application, since the molds 2 are arranged on both sides of the vibration table 1 and the molds 2 on the same side and both sides of the vibration table 1 are symmetrically arranged, it can be ensured that the amplitude transmitted to each mold 2 is consistent, and the density of cement mortar in different molds 2 is uniform and close to consistent.

[0034] In this application, a rubber block 10 is provided between the frame 4 and the concrete foundation 11. The rubber block 10 can reduce the impact on the bottom surface vibration of the entire concrete foundation 11 and help improve the vibration effect of the vibration table 1.

[0035] Vent holes 14 can be processed on both sides of the grouting hole 13 of the mold 2 as needed, so as to realize the cement mortar injection between the plastic drainage pipe 16 and the mold 2. After injection, the cement mortar will form a cement shell 15 on the outside of the plastic drainage pipe 16.

[0036] The mold 2 described in Example 1 is used to produce pipe fittings. The scheme described in Example 2 is suitable for the production of plastic drainage pipes with cement shells. In both cases, the cement mortar inside the mold 2 is vibrated during the production process to improve the density of the cement mortar.

[0037] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
