Purchase
When purchasing hoisting machinery, enterprises should first consider the scope of use, the frequency of work, the utilization rate, the rated lifting capacity and other factors of the enterprise, and select the crane that is suitable for the working level of the unit. Conduct market research based on the proposed technical parameters. The supplier of choice must be a professional crane manufacturer with a special equipment safety license. And to check the compatibility of the processing equipment of the manufacturer, the standardization of production, the advanced nature of the product, and compare the selection of lifting equipment with reasonable price, good quality, excellent performance and complete safety equipment.
After the equipment arrives, check whether the random technical data is complete, whether the random accessories, tools and accessories are consistent with the list, whether the equipment and accessories are damaged or defective, and the unpacking acceptance record is made.
installation
The installation team of the lifting machinery can choose the manufacturer with the qualification to install, and form a service mode of manufacturing, installation and commissioning. In addition, the selected installation unit must be a professional team with the “Special Equipment Installation (Maintenance) Safety Approval Certificate†issued by the provincial quality and technical supervision department, and have the installation qualification to install the corresponding lifting weight. After the installation unit is determined, it is necessary to assist the installation unit to handle the special equipment start-up report before installation, and check whether the installation team's construction organization plan, installation equipment, installation procedures, technical requirements, concealed project acceptance records during the installation process, and self-inspection reports meet the requirements. . After the installation is completed, the installation unit shall be supervised to carry out comprehensive self-inspection, operation test and load test. After confirming the self-inspection, the special equipment inspection agency shall be declared for installation and acceptance. Only after the acceptance has passed and the "Safety Use License" has been obtained can it be put into use. After the acceptance is passed, the user shall file the relevant technical data such as random technical data, installation information and inspection report of the crane. Periodic inspections, overhauls, alterations, accident records, etc. that occur during use in the future are also stored in the hoisting machinery safety technical file.
The structure of the core barrel is generally divided into single - acting double core tube and most of the fishing apparatus. The double tube section consists of an outer tube assembly and an inner tube assembly. The outer pipe assembly includes; The main structure and working principle of the cartridge stopper, cartridge chamber, stable joint outer pipe, diamond reamer and diamond bit are as follows:
(1) Spear structure is composed of spear head and recovery spring. When coring, the fishing device is lowered to the upper part of the inner tube assembly in the drill pipe, and the fishing hook grasps the fishing spear, lifts the fishing device up, picks up the recycling card barrel, and inwardly compressing the cartridge card, so that the inner tube assembly and the outer tube are separated, so that the inner tube assembly is lifted up.
(2) The clip structure is mainly composed of the clip frame, clip, spring and other components. Its function is that when the inner tube sits on the outer tube, the clip expands with the help of the elastic force of the expansion spring and sticks to the inner wall of the clip chamber, so that the drilling tool can achieve positioning.
(3) Buffer structure by spring, locking mother, split pin composition. Protecting the inner tube when pulling the core.
(4) Single action structure is realized by two pairs of thrust bearings.
(5) Adjust the length of the inner pipe assembly and the outer pipe assembly of the structure, and fine-tune the lower shaft and the locking mother to achieve the gap required by the end of the spring seat and the step inside the drill bit.
(6) The fishing structure, also known as the fishing device, is mainly composed of fishing hook, hammer and safety rope. The fishing hook is used to hold the spearhead while fishing the inner pipe, and the weight is used to speed up the fishing device's descent to save fishing time. The safety rope is a thin rope. When the inner pipe is stuck for some reason and cannot be lifted, the safety rope can be forcefully lifted and then the drill can be lifted.
