Abstract
A safety pin is provided and which comprises a cylinder having a first port and a second port arranged in longitudinal ends. A piston is moveably disposed within the cylinder and dividing the cylinder into a first chamber in communication with the first port and a second chamber in communication with the second port. A dowel pin is securely attached to the piston. An adjusting device regulates the position of the piston along a position perpendicular to the first and second directions. And a supplying device directing compressed air to the first chamber through the first port, or directing the compressed air to the second chamber through the second port so as to push the piston and the dowel pin to move along the first direction so as for performing locking and unlocking the equipment. By this arrangement, equipment can be readily locked up and unlocked by the provision of the safety pin.
Description
- The present invention relates to a safety pin, and more particularly, to a safety pin which can be manipulated automatically by means of a driving device.
- For those heavy equipment locked merely by a servo are really dangerous to those maintenance personnel if the equipment do not incorporated a deadbolt or safety pin in additional to the servo. There are plenty of moving parts within the heavy equipment, and during this revolving and transporting, it is mandatory to have a safety pin deadbolted to those moving or revolving parts so as to ensure a safety environment for the working personnel to perform the maintenance, repairs, and inspection. This is extremely important to the safety of those maintenance personnel so as to avoid any safety issues if those equipment are accidently triggered to operate or turned on with power.
- However, any safety pin operated solely by human has a potential risk resulted from human negligence or risking personnel safety. For example, in some application, the safety pin is located at right under equipment which is hanging over the working position in which the safety pin is to set.
- Accordingly, it is necessary to provide a safety pin so as to resolve the prior art issue.
- It is the objective of the present invention to provide a safety pin which can be operated automatically and remotely without risking personnel's safety.
- In order to resolve the technical issue encountered by the prior art, the present invention provides a technical solution by introducing a safety pin which comprises a cylinder having a first port and a second port arranged in longitudinal ends. A piston is moveably disposed within the cylinder and dividing the cylinder into a first chamber in communication with the first port and a second chamber in communication with the second port. A dowel pin is securely attached to the piston. An adjusting device regulates the position of the piston along a position perpendicular to
