Description
Technical field
The utility model belongs to protective device technical field, and in particular to a kind of overhead manned equipment light veil type off-axis protection
Device.
Background technology
When breaking axis occurs for overhead manned equipment, and its it is dangerous, and the device for workers that my mine uses has no this protection
Facility, off-axis protection is developed after manufacturer, and protected mode is：The square metal area for being close to rotary part is installed on the drive wheel
One metal detection Hall sensor has installed driving wheel carrier bracker below driving wheel, and when off-axis occurs for side, driving wheel tenesmus is arrived
On bracket, holding driving wheel prevents from dropping.And the Hall sensor as detection metal and is exported because losing metal signal at this time
Survey, which changes, forces equipment downtime, and mounted sensor is relative complex and is unfavorable for doing off-axis protection test.
Utility model content
Technical problem to be solved in the utility model is：Irrelevant personnel enters rotation section when how to prevent driving wheel from operating
Position lower section, causes danger.
Technical solution used by the utility model is：A kind of overhead manned equipment light veil type off-axis protective device, including
Protection bracket mounted on drive shaft both sides, is mounted under feeler lever the feeler lever to hang down vertically mounted on drive shaft center
The light curtain sending and receiving apparatus of side, holder, control chip, the electromagnetic switch for controlling overhead manned equipment open and close, feeler lever
There are cross sheet metal, light curtain sending and receiving apparatus, electromagnetic switch electric signal connection control chip in lower section.
As a kind of preferred embodiment：The distance at light curtain sending and receiving apparatus both ends is more than the length of drive shaft.
The utility model has the beneficial effects that：When breaking axis occurs, feeler lever block light curtain sending and receiving apparatus to
When realizing emergency shutdown, prevent accident from further increasing, while having service personnel below drive shaft, because light curtain is hidden by personnel
Gear, still in blocking, equipment can not start, and when someone swarms into below the driving wheel of operating, because light curtain is blocked, will stand
It is latched emergency stop, protection life safety, more convenient usually to test off-axis protection, as long as there is shelter to probe into, equipment is
It can stop.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, overhead manned equipment light veil type off-axis protective device, in 4 both sides of drive shaft, respectively installation one is protected
Bracket 3 is protected, 3 upper end of protection bracket is fixed on holder 2, and lower end is in 4 side-lower of drive shaft at L rows, when off-axis occurs,
Protection bracket 3 holds drive shaft 4, and the feeler lever 5 to hang down vertically mounted on 4 center of drive shaft, the lower section of feeler lever 5 has ten
Font sheet metal, when off-axis occurs, feeler lever 5 moves down, and cross sheet metal enters the light curtain transmitting being mounted below feeler lever 5 and connects
Receiving apparatus 1, light curtain sending and receiving apparatus 1 send out off-axis signal to control chip, and control chip controls electricity after receiving off-axis signal
Magnetic switch is closed, and the distance at 1 both ends of light curtain sending and receiving apparatus is more than the length of drive shaft 4.It is in light curtain when there is shelter
When sending and receiving apparatus 1 is intermediate, it will realize that normally opened electromagnetic switch is closed, to realize to being in light curtain sending and receiving apparatus
The protection of repair or other staff among 1.
