Description

Technical Field

[0001] The present application relates to the field of rail vehicles, and in particular to a rail vehicle workshop equipment and a rail vehicle workshop management device. Background Art

[0002] After the rail vehicle is assembled, it enters the commissioning workshop for vehicle commissioning. The commissioning process is divided into: verification and alignment, system function commissioning, static test, and dynamic test. When commissioning the functions of each system, most of the tests are carried out under high voltage. Therefore, ensuring safe power supply in the workshop can complete the production commissioning task in a timely manner.

[0003] In the production process of urban rail vehicles, high voltage (DC750V standard voltage, DC1500V standard voltage, AC25KV standard voltage) will be used for debugging. The high voltage used in the debugging process is provided to the rail vehicle by transmitting power to the contact network. However, there may be climbing operations in the contact network process. This operation needs to be completed on the roof of the rail vehicle, including roof inspection operations, pantograph debugging operations, and air conditioning debugging operations. If the operator is performing a climbing operation, the contact network is powered on to the top personnel, which will endanger the safety of the climbing operators. The climbing operation requires the use of a climbing vehicle, and the climbing vehicle management is key management, that is, the climbing vehicle is used by the key to complete the climbing operation; the contact network power supply is also based on key management, that is, the power supply room is opened by the key, and the switch in the power supply room is operated to complete the power supply to the contact network. The high voltage is delivered under the premise of ensuring safety. During the period, power can only be delivered after judging the on-site situation through human subjective consciousness. It is impossible to accurately determine whether there is a climbing operation, which is prone to safety accidents caused by power supply during the climbing or climbing operation. Summary of the invention

[0004] In order to solve the problems existing in the prior art, the present invention provides a rail vehicle workshop equipment, which can realize key interlocking and restrict operations.

[0019] Key interlocking / interlocking refers to the locking and unlocking of keys by inserting and removing the keys. Key interlocking / interlocking is mechanical, stable, and active, with simple logic control and high safety.

[0020] To this end, the present invention provides a rail vehicle workshop device for interlocking keys; the workshop device is configured with a first eccentric lock 21, a second eccentric lock 22 and a shaft 23, and a rotating shaft 24 of a lock core of the first eccentric lock 21 and a rotating shaft 25 of a lock core of the second eccentric lock 22 are connected through the shaft 23, such as Figure 1 The rotating shafts of the two eccentric locks are connected by a shaft. When the key of the eccentric lock at one end rotates, the rotating shaft of the eccentric lock at the other end is driven to rotate through the shaft, so that the two eccentric locks are in different states to achieve interlocking; the interlocking process is: the first eccentric lock is in an unlocked state (a state in which the key can be pulled out), and the second eccentric lock is in a locked state (a state in which the key cannot be pulled out). The key on the first eccentric lock can be pulled out, and the key on the second eccentric lock cannot be pulled out; when the key on the second eccentric lock needs to be pulled out, the key on the first eccentric lock is turned to put the first eccentric lock in a locked state. During the process of turning the key on the first eccentric lock, the rotating shaft of the first eccentric lock rotates, and the rotating shaft of the second eccentric lock rotates under the drive of the shaft, so that the second eccentric lock is in an unlocked state, and the key on the second eccentric lock can be pulled out; when the key on the first eccentric lock needs to be pulled out again, the key on the second eccentric lock is turned to put the second eccentric lock in a locked state, and during the process of turning the key on the second eccentric lock, the rotating shaft of the second eccentric lock rotates, and the rotating shaft of the first eccentric lock rotates under the drive of the shaft, so that the first eccentric lock is in an unlocked state, and the key on the first eccentric lock can be pulled out.

[0021] The workshop equipment provided by the present invention is also configured with a lock core status monitoring module for monitoring the lock core status of the first eccentric lock and the second eccentric lock; the lock core status monitoring module includes a paddle switch, a data processor and a prompt component. When the first eccentric lock and the second eccentric lock are in a locked state, the paddle switch is closed to stimulate the access data processor, and the data processor generates a driving signal to start the prompt component to prompt the lock core status of the first eccentric lock and the second eccentric lock.

[0022] The paddle switch is located at a position where the lock tongue 26 of the eccentric lock can contact when the first eccentric lock and the second eccentric lock are in the unlocked state. The eccentric lock state is indicated by the closing and opening of the paddle switch. When the eccentric lock is in the unlocked state, the lock tongue 26 of the eccentric lock does not contact the paddle switch, the paddle switch is disconnected, the excitation connected to the data processor is cut off, and the prompt component ends the prompt; when the eccentric lock is in the locked state, the lock tongue 26 of the eccentric lock fits the paddle switch, the paddle switch is closed, the excitation is connected to the data processor, and the data processor generates a driving signal to drive the prompt component to start, thereby achieving a prompting effect. The prompt component can be an LED light, and the number and color types are configured according to the number of eccentric locks to achieve one-to-one prompting.

[0023] In order to better fix the rotating shafts 24 and 25 to the shaft 23, the device uses pins 27 to assemble the rotating shafts and the shaft.

[0024] The workshop equipment provided by the present invention can be used separately. The first eccentric lock and the second eccentric lock are respectively configured with keys configured for different equipment / devices / areas, so as to realize effective management of different operations and effectively avoid the situation where a certain operation cannot be accurately judged due to the ongoing operation, thereby starting another operation and causing an impact; such as the climbing operation of urban rail vehicles and the contact network power transmission operation, the two cannot be carried out at the same time. The present equipment is used to manage the climbing vehicle keys used for the climbing operation and the distribution room / box keys required for the contact network power transmission operation, so that the two operations cannot be carried out at the same time, and the situation where the climbing operator is damaged due to the contact network power transmission operation is completely avoided; the first eccentric lock and the second eccentric lock are respectively configured with keys configured for the same equipment / device / area, so as to meet the requirement that only one person can operate the same business.
