Description

Technical Field

[0001] The invention relates to the technical field of sound barriers arranged on both sides of a road, and in particular to a fiber-reinforced sound barrier forming machine. Background Art

[0002] Sound barriers are set up on both sides of highways, high-speed railways, municipal bridges and subway tracks. They are wall-like structures set up on the sides of railways and highways to reduce the impact of driving noise on nearby residents. At present, there are many types of sound barriers, the most common of which are ordinary metal sound barriers, aluminum alloy sound barriers, ordinary concrete sound barriers, GRC non-metallic sound barriers, photovoltaic sound barriers, etc. Among them, ordinary concrete sound barriers, with an average surface density of 195kg / m, are limited to use in roadbed sound barrier projects, do not generate static electricity, are heavy and difficult to install, and have a service life of ≥25 years; GRC non-metallic sound barriers, with an average surface density of 83kg / m, can be used in roadbed and bridge sound barrier projects, do not generate static electricity, are light and easy to install and bolted, and have a service life of ≥25 years; photovoltaic sound barriers, with an average surface density of 35kg / m, can be used in roadbed and bridge sound barrier projects, are prone to static electricity, are light and easy to install and bolted, and have a service life of ≥15 years. In recent years, a new type of ECP non-metallic sound barrier has appeared on the market, namely, fiber-reinforced non-metallic sound barrier, with an average surface density of 40-80kg / m, which can be used in roadbed and bridge sound barrier projects, does not generate static electricity, is light and easy to install, and has a service life of ≥30 years. This ECP non-metallic sound barrier is a high-pressure vacuum extruded fiber cement board, referred to as ECP board. In the process of producing ECP board, the thickness of the initially formed dry blank board and the top surface groove, width, and the size of the raised part and groove part did not meet the standards, and the product quality could not be guaranteed, resulting in a smooth installation during the later assembly.

[0003] In the prior art, the utility model patent with patent number 201921580579.8 discloses a production line for producing ECP boards, which belongs to the technical field of a complete set of production lines for ECP boards, including: a pretreatment system arranged in sequence according to the production process of ECP boards, which is used to modify solid waste slag to form modified slag; a mud preparation system, which is used to prepare mud using modified slag as one of the raw materials; a plate forming system, which is used to produce mud into ECP dry blank boards; and a finishing system, which is used to finish the ECP dry blank boards to form ECP finished boards. The production line for producing ECP boards of the present invention can achieve the purpose of producing ECP finished boards. The present invention uses solid waste slag (such as phosphogypsum) as the initial raw material, turning waste into treasure, consuming a large amount of solid waste slag (such as phosphogypsum) that pollutes the environment, and improving the increasingly polluted natural environment. However, in the finishing system of this scheme, an edge grinding machine is provided, but its structure is not described in detail, and there is no mention of how to grind the two sides of the dry blank board flush.

[0004] The utility model patent with the patent number of 202311683081.5 relates to a rolling integrated forming device for metal unit plates of sound barriers, including a base and a feeding mechanism that can assist workers to transfer the rolled metal unit plates; the base is provided with a conveying module, a rolling module, a cutting assembly and a shaping mold; the shaping mold is fixedly installed on the top of the base, used to assist the metal unit plates in rolling to form a shaping structure; the rolling module can roll and shape the metal unit plates; the conveying module can drive the metal unit plates to move on the shaping mold; the cutting assembly can cut the metal raw materials into equal parts. The present invention mainly drives the slot rod to swing by a reciprocating motor, pushes the push plate to the left, pushes the metal unit plate onto the hook column, and lowers the metal unit plate by resetting the hook column, without the need for workers to move it down, which can reduce the physical exertion of workers. However, this scheme also does not explain which method is used to machine the dry blank plate in the machining system.

[0005] None of the above-mentioned prior arts solves the problem of how to make the dry blank plate reach the standard size, and the product quality cannot be guaranteed. At present, there is an urgent need for an automatic continuous trimming device for non-metallic sound barriers, which can trim the raised part, groove part and top surface of the sound barrier dry blank plate at the same time without pausing, and through the smooth connection between the processes, it changes the processing method of the single machine in the existing sound barrier machining process, reduces the labor cost, improves the production efficiency and product quality, and after forming the standard size, it plays a favorable condition for the subsequent assembly.
