Detailed Description
Referring to fig. 1 to 6, a manual power-off mechanism for a barrier machine includes a barrier machine housing, a node switch 12 installed inside the barrier machine housing for controlling a circuit loop of the barrier machine, a through hole provided on the barrier machine housing, and a manual member capable of entering the through hole;
the node switch 12 includes a limit post capable of being elastically compressed to a switch stroke, and the manual member can be compressed to the switch stroke by pressure after entering the through hole, so that the circuit of the railing machine is disconnected.
The rail machine also comprises a track piece which is arranged on the rail machine shell and used for transmitting the pressure generated by the manual piece to the limit post, wherein the track piece can reset after the pressure born by the track piece disappears, and the reset can be manually adjusted or automatically adjusted; because manual adjustment is complicated, the shell needs to be opened for resetting, and preferably, the track piece realizes automatic adjustment through elastic reset.
The barrier machine shell comprises a barrier machine base 11 and a barrier machine shell 21 fixedly connected to the upper end of the barrier machine base 11;
the track piece comprises a guide bracket 31 fixedly connected to the inside of the breast board machine shell 21 through bolts, a cam groove column 32 riveted on the guide bracket 31, a guide rod 41 slidingly connected in the cam groove column 32 and on the guide bracket 31, an elastic cylindrical pin 43 mounted on the guide rod 41 and matched with the cam groove column 32, a pulling piece 42 fixedly connected to the upper end of the guide rod 41, and a compression spring 44 sleeved on the guide rod 41;
the manual part can push the poking piece 42 to rotate after entering the through hole, so that the elastic cylindrical pin 43 moves on the cam groove column 32 to enable the guide rod 41 to descend, and when the manual part is pulled out of the through hole, the guide rod 41 is reset through the compression spring 44.
The technical scheme of automatic power-off when the existing barrier machine is manually operated by a worker is that a switch of a control cabinet beside equipment is powered off, an internal switch of the barrier machine is powered off, and the like. However, the scheme has complicated operation flow, the operation of the control cabinet, the operation of opening the interior of the breast board machine and the like need a certain technical basis, and the operation has a certain influence on the interior of the equipment. And the operation of the control cabinet and the operation of opening the interior of the breast board machine equipment have certain potential safety hazards.
The manual part is inserted into the housing of the breast board machine and is connected with the output shaft of the motor 51 of the breast board machine, the hand crank 61 is operated through the motor main shaft cylinder to realize the manual operation of the breast board machine, and when the hand crank 61 is inserted into the breast board machine, the hand crank 61 can be simultaneously and effectively automatically powered off to finish the safety protection of manual operation staff, the whole process is inserted without other redundant operation, the working procedure is simple, the mechanical structure form ensures that the equipment failure rate is low, and the equipment is not affected by other factors.
Specifically, when the railing machine needs to be manually operated in a power-off mode, the lock cover 22 is opened, the hand crank 61 is inserted into the lock hole 23, the hand crank 61 pushes the pulling piece 42 open, the pulling 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 spiral of the cam groove column 32, so that the guide rod 41 moves downwards, the limiting column of the node switch 12 positioned on the side edge of the railing machine base is compressed, 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 limiting column of the node switch 12 to a switch stroke, the node switch 12 controls the circuit of the railing machine to be disconnected, and the internal power-off of the railing machine is ensured.
When the railing machine is manually operated, the hand crank is pulled away from the motor shaft, and the railing machine is still powered off to protect staff.
When the handle 61 is pulled out from the side rail machine housing 21, the guide bar 41 moves upward by the urging force of the compression spring 44, at this time, the elastic cylindrical pin 43 on the guide bar 41 spirals upward along with the groove on the cam groove 32, the bottom of the guide bar 41 releases the limit post of the node switch 12, the node switch 12 resets, the side rail machine circuit is controlled to be turned on, and the guide post pulling piece 42 returns to the initial position.
The railing machine shell 21 is provided with a lock hole 23 forming the through hole.
The lock hole 23 is provided with a lock cover 22 which can be opened and closed relatively to the lock hole, and the lock cover 22 can be hinged at one end and is locked at the other end, so that the lock hole can be opened and buckled relatively. Or may be threadably coupled to the locking hole 23.
The manual part 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 barrier machine motor 51 is also arranged in the barrier machine shell, and a motor output shaft 52 is arranged on the barrier machine motor 51; the maximum travel of the hand piece into the end of the boom machine housing is against the free end of the motor output shaft 52.
More specifically, the handle 61 is inserted into the lock hole 23 and then is further inserted into the output shaft of the barrier motor 51, the end of the output shaft of the barrier motor 51 is of an outer hexagonal structure, the end of the handle 61 corresponding to the end is provided with an inserting hole which is of an inner hexagonal structure, and thus after the handle 61 is inserted into the output shaft of the barrier motor 51, the handle 61 can be buckled with the output shaft of the barrier motor 51, and then the handle 61 can be rotated by shaking the output shaft of the barrier motor 51.
The purpose of the rotation of the motor output shaft of the breast board machine is as follows: the railing motor 51 rotates to drive the railing to open and close. The purpose of inserting the hand crank 61 into the output shaft of the electric motor 51 of the barrier machine is to drive the barrier machine by inserting the hand crank 61 into the barrier machine to drive the output shaft 51 of the barrier machine to rotate if the field is not electrified, but when the barrier machine needs to be lifted or lowered, or when other reasons such as temporary driving, failure of the controller and the like need to manually operate the barrier machine. However, there is a great risk that when the hand crank 61 is buckled with the output shaft of the barrier motor 51, a person operates the hand crank 61 to drive the output shaft of the barrier motor 51, and at the moment, the output shaft of the barrier motor 51 needs to be ensured not to be suddenly started, so that the hand crank 61 is prevented from being driven to rotate to hurt operators, or the barrier is prevented from being suddenly electrified, and when staff does not operate, a barrier is suddenly started to cause injury to the staff. When operating personnel overhauls the barrier machine, also need the barrier machine to cut off the power supply accurately, consequently manual power-off mechanism just can guarantee that the barrier machine cuts off the power supply when staff such as manual operation barrier machine, maintenance barrier machine closely operate, and can not switch on the start-up barrier machine suddenly, ensures staff's safety.
