Pengpu develops the first domestic gas permeable caisson excavator

Pengpu Heavy Industry Equipment Factory relies on the excellent product quality, relying on the mature products such as steel machine, heat treatment cold bed and roller table to stand in the metallurgical industry, and then extend the tentacles to the tunnel construction machinery field with broad development space, following the municipal The two companies initially cooperated in the production of high-precision reinforced concrete segment steel molds for the Tibet Road Cross-river tunnel project, and jointly created the first domestic gas pressure caisson excavator. The product has passed the user acceptance and is currently in Tibet. Road construction site service. The second edition of the "Labor" on November 23 also published the news of the successful trial of the compressed caisson excavator.

In order to better guarantee the manufacturing quality of the product and establish a good image of the company, Pengpu Heavy Industry Equipment Factory has set up a leading group of “Municipal Second Company Compressed Caisson Excavator Project” after the contract, which is the director of the branch factory. The team leader and the technical deputy director Zhu Ronghua served as the quality in charge of the project. The relevant departments identified the responsible persons, defined the quality responsibility, formed the secondary responsibility system, and formulated the “Pneumatic caisson excavator quality plan”. To guide the whole process of product production. In the procurement process of major forgings, purchased materials and accessory parts, the Business Section strictly follows the corresponding procedure documents of the quality system and relevant supporting documents. The technical department first carefully and carefully digested the drawings. In order to facilitate the processing and production, and to meet the processing capacity of the equipment, on the basis of the requirements of the relevant national standards, technical specifications, technical specifications of the product technology agreement, etc., after the user’s consent, some parts were made. Appropriate modification, the manufacture and processing of important parts, the use of high-precision processing equipment, according to the drawings and assembly of general technical conditions to prepare the technical procedures, and design of the process equipment, to ensure that the quality of product processing technology within the scope of work correctly and effectively run. The inspection department is divided into B and C secondary inspections for product inspection. The B-level inspection is an important part of the unit, and the important items are fully inspected and measured. The C-level inspection is for the general parts in the unit, the full or sampling inspection of the incoming materials, filling in the inspection records and inspection conclusions, and making the material identification. For the main raw materials, purchased parts, outsourced parts and supporting parts of the project, relevant quality certificates or certificates must be provided, and they should be kept for inspection when entering the factory. During the processing, the inspectors shall make the first inspection in time, strengthen the inspection inspection, and strictly complete the inspection. According to the process regulations, the surface peening, pickling phosphating and painting require pretreatment, etc., for the exposed parts with the embedded requirements of the process, select the painter with higher technical level, responsible for the scraping of the blank and the polishing of the blank. . The inspectors shall focus on re-examine the exposed welded parts. If they do not meet the requirements, they must be repaired and polished and tested. Before the workpiece is painted, the surface is cleaned and sprayed according to the coating thickness specified by the technical standards. After more than five months of trial production and commissioning, the gas-filled caisson excavator finally passed the user acceptance.

The successful completion of the project verified the overall operational capability of Pengpu Heavy Industry Equipment Factory. During the project development process, Baosteel Cold Bed, Xianggang Cold Bed, Angang Roller, Shougang Loading and Exporting Machine and other products were produced simultaneously. Collaboration and mutual cooperation ensure the successful development of the compressed caisson excavator and ensure the smooth progress of other projects. The successful completion of the development project marks that the factory has the confidence and ability to enter new product areas and markets under the correct leadership of the company.
