Description

A flange connection pull-out pin type emergency release device Technical Field

[0001] This utility model relates to the field of emergency detachment device technology, and in particular to a flange connection pull-out pin type emergency detachment device. Background Technology

[0002] Emergency release devices prevent leaks caused by accidental hose breakage. They are applicable in various fields, including unloading from ship to shore, tank loading and unloading on highways and railways, and other stationary and mobile fluid storage devices, such as loading arms and fluid transfer arms connected to transport vehicles. Threaded clamp-type emergency release devices, flange clamp-type emergency release devices, and flange pull-out pin-type emergency release devices are all types of emergency release devices. When installing a flange pull-out pin-type emergency release device, the flange of the device must be connected to the flange of the pipeline, and one person should be needed to support the device while pulling it apart. The installation of a pin-type emergency release device requires another person, making it impossible for a single person to complete the task. A Chinese patent discloses a "flange connection pull-out pin type emergency release device" (application number CN201820216550.0), which achieves a sealing effect through the use of a clamp, rubber, clamping holes, clamping blocks, and protrusions, preventing leakage of liquid substances and avoiding waste. However, it cannot solve the problem that when installing the flange-connected pipe flange of the pull-out pin type emergency release device, one person needs to support the device while another person installs it, making it impossible for a single person to complete the task. Summary of the Invention

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a flange connection pull-out pin type emergency release device. By rotating the double-acting screw on the outer side of the second fixed frame, the clamping frame threaded to both ends of the double-acting screw can move symmetrically, so that the clamping frame clamps the flange slot, temporarily fixing the main body of the device to the flange without the need for support from others, making it convenient for a single worker to install the main body of the device. By rotating the screw motor on the outer side of the first fixed frame, the position of the second fixed frame threaded to the screw motor can be adjusted, which also allows the clamping frame on the second fixed frame to be adjusted to clamp flanges in other positions. An LED light is installed above the second fixed frame to illuminate the position of the flange, which is convenient for workers to install in dim conditions. At the same time, by extending and retracting the telescopic rod on the fixed plate, the movable frame connected to the telescopic rod can be adjusted in position with the LED light.

The anti-slip texture of the handle design can effectively increase the user's grip on the handle during operation and improve the comfort of operation.

[0012] Compared with existing technologies, this flange-connected pull-out pin type emergency release device allows for symmetrical movement of the clamping frame threaded at both ends of the double-ended screw rod on the outer side of the second fixed frame. This clamping frame holds the flange in its slot, temporarily fixing the main body of the device to the flange without the need for assistance, making it convenient for a single worker to install the device. The rotation of the screw motor on the outer side of the first fixed frame allows the second fixed frame, threaded to the motor, to be adjusted in position, facilitating the adjustment of the clamping frame on the second fixed frame for clamping flanges in other locations. An LED light above the second fixed frame illuminates the flange position, aiding installation in low-light conditions. Furthermore, the telescopic rod on the fixed plate allows the movable frame connected to the telescopic rod to be adjusted in position, along with the LED light. Attached Figure Description
