Long core tube disassembling and assembling machine

Abstract

The invention discloses a long core tube disassembling and assembling machine. The machine comprises a top core main frame, a top core propelling assembly installed on the top core main frame, a bearing bottom frame fixedly connected to the rear side of the top core main frame, a positioning and supporting assembly fixedly connected to the bearing bottom frame and used for bearing a double-hole formwork vehicle, and a ferrying guide rail fixedly connected to the side part of the bearing bottom plate and used for ferrying the double-hole formwork vehicle to the positioning and supporting assembly; the top core propelling assembly comprises a top core shaft set, a core pipe jacking set frame fixedly connected to the rear end of the top core shaft set, a main oil cylinder set frame fixedly connected to the middle of the top core shaft set, a main propelling oil cylinder fixedly connected to the middle of the top core main frame and a propelling pulley mechanism connected to the top core main frame and the core pipe jacking set frame; and a propelling rod of the main propelling oil cylinder is fixedly connected with the main oil cylinder set frame. The stroke of the propelling device for disassembling the long core tube is shortened, the procedures of disassembling the core tube, cleaning and maintaining the core tube and assembling the core tube into an empty mold are completed ata time, the core tube is disassembled and assembled accurately and rapidly, and the working efficiency is high.

Description

technical field [0001] The invention relates to a machine for disassembling and assembling a long core tube, which is used for disassembling and assembling a short core tube in a double-hole plate mold, and belongs to the technical field of assembly-type building production molds. Background technique [0002] The double-hole plate is used as an assembled wall panel for prefabricated buildings. Its structure is to open a through hole in the middle for inserting steel bars. The through holes at the front and rear ends cross the through holes at the left and right ends. Concrete is poured in the hole, and after solidification, the building wall panel is formed. [0003] In the process of making a double-hole plate, the mold needs to be removed after the double-hole plate is formed, and the core tube must be pulled out first. [0004] The extraction of the core tube in the existing double-hole plate is mostly done manually, which is labor-intensive and time-consuming, resultin...

Problems solved by technology

[0004] The extraction of the core tube in the existing double-hole plate is mostly done manually, which is labor-intensive and time-consuming, resulting in low production efficiency; at present, some ejector pins are used to eject the core tube in the double-hole plate mold. , there are still the following problems: the existing ejector rod adopts a vertical frame, which not only takes up a large space, but also is inconvenient to operate; it is not possible to dismantle multiple side-by-side core tubes in the double-hole plate mold at one time; the removed core tubes need to be moved to other work There is also no function of inserting the core tube into the double-hole plate empty mold; the length of the core tube in the mold for producing a long double-hole plate is also long, and the existing removal method is not only laborious, but also The propulsion device requires a large stroke, the thrust transmission stroke is long, and the propulsion device requires high precision, resulting in high device cost and inconvenient operation; removing the core tube, maintaining and cleaning the core tube, and loading the core tube, all processes need to be moved to an independent It is carried out at the equipment, the process is complicated, the operation process is cumbersome, and the process flow is complicated, resulting in low production efficiency of double-hole plate
