Dismounting and mounting machine for prefabricated box culvert mould core

Abstract

The invention discloses a dismounting and mounting machine for a prefabricated box culvert mould core. The dismounting and mounting machine is composed of hydraulic cylinders, a hydraulic station, a multi-way valve, an upper vehicle frame, upper vehicle tracks, upper vehicle wheels, upper vehicle wheel driving motors, a lower vehicle frame, lower vehicle tracks, lower vehicle wheels and lower vehicle wheel driving motors, wherein the four hydraulic cylinders are provided and are fixedly arranged at two sides of the upper vehicle frame; the multi-way valve and the hydraulic station are arranged on the upper vehicle frame; the multi-way valve is connected between the hydraulic station and the hydraulic cylinders through an oil transmission pipeline; the upper vehicle frame, the upper vehicle tracks, the upper vehicle wheels and the upper vehicle wheel driving motors form an upper sliding mechanism; the lower vehicle frame, the lower vehicle tracks, the lower vehicle wheels and the lower vehicle wheel driving motors form a lower siding mechanism; and the upper sliding mechanism is parallel to the lower sliding mechanism, and the connecting way of the upper sliding mechanism is similar to that of the lower sliding mechanism. The dismounting and mounting machine for the prefabricated box culvert mould core can be used for self-loading and self-unloading a box culvert mould core, loading and unloading by using a crane are not needed, and transporting by a fork lift truck is not needed, so that the loading and unloading expenses are greatly reduced; and when the mould core is removed, the dismounting and mounting machine is high in precision, good in stability, free of deflection and flexible in operation.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a prefabricated box culvert core dismantling machine. Background technique [0002] The construction of underground comprehensive pipe corridors has been widely carried out across the country. Jilin Province plans to build 1,000 kilometers of underground comprehensive pipe corridors from 2015 to 2018, with a total investment of about 100 billion yuan. For this reason, the construction of urban underground comprehensive pipe corridors has kicked off in the whole province. The applicant actively responded to the call of the state, changed its thinking and concept, transformed its investment direction, and invested all its technical strength and effective resources in the construction of the underground comprehensive utility corridor. [0003] In this reform, the leading idea for the construction of underground comprehensive pipe corridors is to break the ...

AI Technical Summary

Problems solved by technology

The biggest difficulty in the process of assembling and disassembling the box culvert mold is the assembly and disassembly of the box culvert mold core. Due to the large volume and weight of the box culvert mold core, it cannot be disassembled without a special machine. Secondly, the box culvert mold core The precision of installation and disassembly is high, and the installation process is required to be stable. Any deviation will directly affect the quality of the box culvert

In the existing technology, forklifts and cranes are basically used to transport and load the box culvert mold core, which requires high operating skills for forklift workers, and the movement of the box culvert mold core is controlled manually, and the accuracy and stability are easily affected

In addition, this operation is basically carried out outdoors, which requires a lot of indoor space in the factory building
