Description

Technical Field

[0001] The utility model mainly relates to the technical field of flowmeter transportation and protection, and specifically relates to a fixed chain hoisting device. Background Technique

[0002] A mass flowmeter is an instrument used to measure the mass flow rate of a fluid. It can accurately measure the flow rate without being affected by changes in fluid temperature, pressure, density, etc. One of the core components of a mass flowmeter is the vibration tube, also known as the vibrating tube or measuring tube. The vibration tube is the key part for realizing the measurement of fluid mass flow in a mass flowmeter. Its working principle is usually based on the Coriolis effect. The vibration tube is usually one or two U-shaped or S-shaped pipes made of metal or other strong materials. They have high mechanical strength and elasticity. When the fluid passes through the vibration tube, the vibration tube will vibrate at a certain frequency under the action of an external driving device. According to the principle of the Coriolis force, the flowing fluid in the vibrating tube will be subjected to a force proportional to the fluid velocity and mass flow rate. This force will cause changes in the vibration frequency and amplitude of the vibration tube. By measuring these changes, the mass flow rate of the fluid flowing through the vibration tube can be accurately calculated.

[0003] The vibration tube is a very precise and fragile component in a mass flowmeter. It is usually made of thin-walled metal or other sensitive materials. During the installation process of the unsealed vibration tube, hoisting is required for transportation. Unsealed means that the vibration tube has no external protective shell or covering to absorb external impacts and pressures. Therefore, it is more likely to be directly damaged during handling. During hoisting, if the operator does not follow the correct handling procedures, such as using improper lifting tools, too fast hoisting speed, improper selection of lifting points, or using the wrong hoisting method, it is easy to cause collisions between the vibration tube and the hoisting structure, resulting in damage to the vibration tube. Moreover, different-sized vibration tubes require the replacement of different types of hoisting, which is very inconvenient. Frequent replacement of lifting tools reduces work efficiency.
