AI Technical Summary

Technical Problem

Traditional automatic pass-through hydraulic presses for gas cylinder testing lack the ability to clamp and secure the cylinders, causing them to tip over easily during testing, which affects the normal use and practicality of the device.

Method used

An automatic pass-through hydraulic press was designed, comprising a transmission component, a clamping mechanism, a flushing component, a pumping component, and a fan component. The press uses a turntable to drive a connecting rod and a bevel gear system to achieve stable clamping of the gas cylinder. It performs water pressure testing and wastewater recycling through a spray pipe and a pumping pipe. The fan component is used to dry the inside of the gas cylinder.

Benefits of technology

It achieves stable clamping of the gas cylinder, preventing tipping, and can automatically complete water pressure testing and wastewater recycling. The operation is quick and improves the practicality and testing efficiency of the device.

Abstract

This utility model discloses an automatic through-type hydraulic press for steel cylinder inspection, relating to the technical field of inspection devices. It includes a base, a transmission assembly on the top of the base, a chamber fixedly connected to the top of the base, a viewing window on one side of the chamber, a water tank fixedly connected to the front of the base, a flushing assembly and a pumping assembly at the upper end of the transmission assembly, and a fan assembly on one side of the pumping assembly. The transmission assembly includes a first motor fixedly connected inside the base, a limiting groove on the top surface of the base, a first threaded rod rotatably connected inside the limiting groove, the first threaded rod being fixedly connected to the output end of the first motor, a moving block slidably connected inside the limiting groove, and two sets of adjacent clamping blocks jointly clamping and fixing the bottom of a group of steel cylinders. This allows the mounting base to stabilize the steel cylinders, facilitating subsequent inspection by the device and preventing the cylinders from tipping over.
