The present invention relates to a transfer device for a mold for a modified sulfur polymer concrete (MSPC) product, and more particularly, to a mold transfer device used for a manufacturing process of an MSPC product that requires heating and cooling of a mold in a manufacturing process.

In general, concrete is widely used as a representative construction material because of its high compressive strength and durability, low cost and abundance. Today, with the development of the industry, various structures are gradually increasing in size and diversification, and accordingly, there is an increasing need for concrete with improved physical properties than conventional concrete. In particular, there is a great need to remedy the shortcomings of large brittleness, small tensile strength and easy cracking, which are the biggest drawbacks of concrete. In addition, concrete is weak in an acidic environment and easy to proliferate various bacteria, a situation in which concrete having high chemical resistance and antibacterial property is required. In addition, as various structures are gradually enlarged and diversified, there is an increasing need for concrete having improved durability compared to conventional concrete.

On the other hand, in concrete pipes such as sewage pipes, sewage and wastewater pipes and underground hollow pipes, the pipe is corroded or cracked due to the reaction of harmful components such as acid mixed with sewage, sewage and waste water and cement components. Occurrences and ultimately polluting the soil often occur. In addition, when communication between the existing concrete pipe and other concrete pipes is required, the pipe is drilled or hammered, but due to the brittleness of the concrete pipe may cause cracks in the pipe during the drilling operation. On the other hand, after connecting the pipe and the joint is treated with cement mortar, but also the joint is not well adhered to the cement mortar, the leakage occurs in the joint often occurs to contaminate the ground. In addition, when repairing the damaged existing concrete pipes with cement mortar, the existing concrete pipes and cement mortar are not easily adhered to, so it is not easy to completely repair them.

As a method of compensating the disadvantages of the concrete pipe, a method for manufacturing an MSPC product was developed by pouring a concrete composition containing sulfur polymer into a mold installed with reinforcing bar.

The manufacturing method of the MSPC product is disclosed in Korean Patent Application No. 10-2003-0008279. The manufacturing method of the said MSPC product includes a process of assembling a mold and placing reinforcing bars in a mold, heating the mold to a predetermined temperature in advance, installing a heated mold on a centrifugal molding table, and a sulfur polymer. Mixing the prepared concrete composition at a temperature of about 100 to 160 ° C., transferring the concrete composition to a mold of a centrifugal molding table while maintaining the temperature, and casting the product by rotating the mold using a centrifugal molding table. It includes a step of forming, a step of moving the mold having completed product molding to a cooling place to cool it, and a step of demolding the mold having completed cooling. The preheating of the mold is intended to prevent the temperature of the concrete composition from sharply lowering during concrete composition pouring and product molding.

As such, the manufacturing method of the MSPC product includes the step of transferring the mold from the mold assembly and reinforcement site to the heating device, and the process of moving the mold from which the product molding is completed to the cooling place. This movement is done by a crane. That is, the crane installed on the ceiling of the factory moves the mold while moving in the horizontal and vertical directions.

However, the crane not only requires a large installation cost, but also has a problem that it is difficult to store the mold inside the heating device when the upper surface of the heating device is closed. In addition, when the mold falls to the ground while the mold is being transferred, not only the mold may be broken, but also work equipment may be damaged or an operator may be injured.

In order to solve this problem, a method of transferring a mold using a transfer device such as a chain has been proposed. The chain is installed in a predetermined frame in a caterpillar to load the mold and transfer it to a heating device or cooling place. Thus, the chain can safely and effectively move heavy molds, as well as low installation costs. However, there is a problem in that the frame inside the heating device and the chain repeatedly reciprocating inside and outside the heating device repeat thermal expansion and thermal contraction due to high temperature heat. That is, the thermal stress may be generated to bend or crack the chain or frame.

The present invention has been made to solve the above problems, it is possible to effectively move the mold to the heating device even if the upper surface of the heating device is sealed, it can be installed at a low cost as well as damage to the mold or work equipment or worker injury It is an object of the present invention to provide a transfer device for molds for MSPC products without concern.
