The technical scheme of automatic power-off of the existing fence machine during manual operation of workers is that a switch of a control cabinet beside the equipment is powered off, a switch inside the fence machine equipment is powered off and the like. However, the operation flow of the above scheme is complicated, a certain technical basis is needed for the operation of the control cabinet and the operation of opening the interior of the rail machine equipment, and the like, and certain influence is also exerted on the interior of the equipment. And the control cabinet operation and the operation of opening the interior of the rail machine equipment have certain potential safety hazards.

According to the scheme, the manual piece is inserted into the rail machine shell and the 51 output shaft of the rail machine motor, the hand crank 61 is rocked to move through the motor spindle cylinder so as to realize the function of the manual operation rail machine, and when the hand crank 61 is inserted into the rail machine equipment, the hand crank can be effectively and automatically powered off simultaneously, the safety protection of manual operation workers is completed, the whole process is inserted, other redundant operations are not needed, the process is simple, the fault rate of the equipment is low due to the mechanical structure, and no other influences are caused on the equipment.

Specifically, when the rail machine needs to be powered off and manually operated, the lock cover 22 is opened, the hand crank 61 is inserted into the lock hole 23, the hand crank 61 pushes the poking piece 42 open, the poking piece 42 drives the guide rod 41 to start rotating, when the guide rod 41 rotates, the elastic cylindrical pin 43 on the guide rod 41 is limited by the cam groove column 32, the elastic cylindrical pin 43 moves downwards along with the groove type spiral of the cam groove column 32, the guide rod 41 moves downwards, the limit column of the node switch 12 on the side edge of the rail machine base is compressed, meanwhile, the compression spring 44 in the guide rod 41 is compressed until the hand crank 61 is inserted into the motor output shaft 52, at the moment, the guide rod 41 compresses the limit column of the node switch 12 to a switch stroke, the node switch 12 controls the rail circuit to be disconnected, and the internal power failure of the rail machine is guaranteed.

After the rail machine finishes manual operation, the hand crank is taken out from the motor shaft, and the rail machine is still powered off at the moment so as to protect workers.

When the hand crank 61 is pulled out from the casing 21 of the gate machine, the guide rod 41 moves upwards due to the thrust of the compression spring 44, the elastic cylindrical pin 43 on the guide rod 41 spirals upwards along with the groove on the cam groove column 32, the bottom of the guide rod 41 loosens the limit column of the node switch 12, the node switch 12 resets, the circuit loop of the gate machine is controlled to be connected, and the guide column shifting piece 42 is restored to the initial position.

And a lock hole 23 forming the through hole is arranged on the casing 21 of the wood hurdle machine.

The lock hole 23 is provided with a lock cover 22 which can be opened and closed relative to the lock hole, and the lock cover 22 can be a lock card with one end hinged and the other end locked, and can be rotated relative to the lock hole to realize opening and buckling. Or may be screwed into the locking hole 23.

The hand piece comprises a hand crank 61 penetrating into the lock hole 23, and the hand crank 61 is labor-saving in structure and convenient to use.

A wood hurdle machine motor 51 is further installed in the shell of the wood hurdle machine, and a motor output shaft 52 is arranged on the wood hurdle machine motor 51; the maximum travel of the hand piece into the end of the gate housing is against the free end of the motor output shaft 52.

More specifically, the hand crank 61 is inserted into the lock hole 23 and then continuously inserted into the output shaft of the log hurdle motor 51, the shaft end of the output shaft of the log hurdle motor 51 is of an outer hexagonal structure, and the end of the hand crank 61 corresponding to the shaft end is provided with an insertion hole of an inner hexagonal structure, so that the hand crank 61 can be buckled with the output shaft of the log hurdle motor 51 after being inserted into the output shaft of the log hurdle motor 51, and then the hand crank 61 is shaken to drive the output shaft of the log hurdle motor 51 to rotate.

The purpose of the rotation of the output shaft of the rail machine is as follows: the motor 51 of the machine rotates to drive the opening and closing of the gates. The purpose of inserting the hand crank 61 into the output shaft of the motor 51 of the log splitter is to drive the output shaft 51 of the motor of the log splitter to rotate when the log splitter needs to be lifted or lowered or the log splitter needs to be manually operated due to other reasons such as temporary driving, controller failure and the like when the power is not supplied on site. But doing so has very big risk, when crank 61 and the lock of rail machine motor 51 output shaft, people's operation crank 61 drive rail machine motor 51 output shaft, need ensure at this moment that rail machine motor 51 output shaft can not suddenly start to avoid driving crank 61 and rotate and injure operating personnel, or avoid rail machine to go up the electricity suddenly, the railing suddenly starts when the staff does not operate, can look for the staff and cause the injury. When operating personnel overhauls the fence wood machine, also need the outage that the fence wood machine can be accurate, therefore manual outage mechanism is exactly in order to be able to ensure the fence wood machine outage when staff such as manual operation fence wood machine, maintenance fence wood machine closely operate, and can not switch on suddenly and start the fence wood machine, ensure staff's safety.
