Description

Technical Field

[0001] The invention belongs to the field of repair and maintenance of machinery and equipment, and designs a one-button automatic locking and tagging device. Background Art

[0002] When enterprises manufacture, install, repair, maintain and perform other operations on machines throughout their life cycle, unreleased energy (electrical energy, potential energy, thermal energy, etc.) may be accidentally released and cause harm to operators. "Lockout / tagout" is one of the commonly used safety operation methods to prevent the accidental release of these dangerous energies. The GB / T33579 "Lockout / tagout for Mechanical Safety Hazardous Energy Control Methods" standard has been specially formulated to provide detailed requirements and definitions for lockout and tagout.

[0003] Lockout and tagout mainly consists of five main steps: notification, closing, locking, tagging and releasing. However, in actual operation, maintenance personnel often forget some of the lockout and tagout steps, choose incorrect locking positions, choose inappropriate locks for tagging and locking, forget to release and detect residual energy, or even do not perform lockout and tagout because they find it troublesome. As a result, lockout and tagout are not implemented in a standardized manner or are ineffective and the implementation effect is unsatisfactory:

[0004] Through long-term practice and research on lockout and tagout, a "one-button automatic lockout and tagout device" has been developed. By setting controllers for various energy sources used by the equipment and connecting them to the device for centralized control; and through the designed electrical mechanical device, the four steps of closing, locking, tagging and releasing the lockout and tagout are automatically controlled, thus realizing one-button lockout and tagout, greatly reducing the complexity of tagging and locking, and significantly improving the procedural integrity, step orderliness, effect effectiveness and implementation efficiency of lockout and tagout, thereby ensuring the life safety of maintenance personnel. Summary of the invention

[0005] Purpose of the invention: To reduce the difficulty of tagging out and locking out, improve the integrity and orderliness of the tagging out and locking out procedures, and realize the automation of tagging out and locking out;

[0006] Technical solution: To achieve the above purpose, the technical solution of the present invention is as follows: BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Attached Figure 1 It is a schematic diagram of the functional modules of the present invention;

[0008] Attached Figure 2 It is a circuit structure diagram of the present invention. DETAILED DESCRIPTION

[0009] This device can achieve the above functions through the designed circuit and the following technical solutions:

[0010] (1) Install switches with permission control (such as key switches, fingerprint locks, code scanning switches, etc.) to ensure that unauthorized personnel cannot operate them. This ensures that the one-button lockout and tagout must be activated and closed by the maintenance operator himself to prevent misoperation;

[0011] (2) Connect the signals of various energy sources or energy opening and closing devices to this device to ensure that all energy sources can be closed and opened with one button;

[0012] (3) One-button automatic power off: Energy control startup is achieved through a trip device, electromagnetic main valve, electric valve, etc., and all startup controllers are connected to the authority control switch described in (1) to achieve one-button control;

[0013] (4) Automatic residual energy release: By installing a discharge device, a gas release device, etc., after one-click opening, the energy switch is turned off and the residual energy release is turned on, thereby ensuring that the residual energy is consumed;

[0014] (5) Automatic residual energy monitoring: by installing current and voltage meters, pressure gauges and other devices to detect the energy status of the line pipeline and display the readings, so that operators can intuitively see the residual energy release status and avoid being harmed by energy;

[0015] (6) Automatic locking: The control switch area is locked by installing a controlled lock. When it is opened with one button, the remote control lock is locked, and personnel cannot open the panel to perform power supply operations, thereby preventing unauthorized personnel from operating the panel incorrectly. If the operator locks the panel with one button and takes the key away, the switch area cannot be opened without reinserting the key and releasing the key with one button, thereby ensuring that unauthorized personnel cannot open the energy source during maintenance.

[0016] (7) Automatic tag-out reminder: Through the designed lighting device, the tag-out lock light will light up after one-click opening, reminding that the line is in operation and unauthorized personnel are not allowed to operate;

[0017] (8) Final confirmation prompt: This device uses a designed control system to detect the feedback signal of the above operations, determine that the system has completed power outage, gas outage, and energy outage, and then give a completion signal indication.

[0018] Operators must use a special key (not limited to physical keys, but also scan code switches / fingerprints / faces, etc.) to operate. After the key switch is turned on, wait for the remaining energy to be released, check that the voltage, current, and pressure gauges are all 0, and wait for the tag lock operation completion signal light to light up, then remove the key to carry out maintenance. During maintenance, the equipment maintenance sign lights up to remind others not to operate. At the same time, because the switch area panels are locked, other personnel cannot start the energy switch that touches the equipment, thus avoiding accidental

[0019] operate;

[0020] After the maintenance personnel finish, they use the special key to open it, the remaining energy is released and closed, the valve starts, and the valve opens.

[0021] When the panel is opened, the personnel must manually supply power (secondary confirmation), thus ensuring the safety of equipment maintenance personnel;

[0022] At the same time, the switch panel of this device has a lock hole. When multiple people are repairing it, each person must physically lock it.

[0023] Repair completed

[0024] After that, all persons must remove the locks before power can be supplied to ensure the safety of all maintenance personnel.
