Abstract
The utility model discloses an anti-derail device for a bridge type loader of a heading machine. The anti-derail device includes a sensor fixed on the end of the loader, and the sensor is connected with a headlight of the heading machine. When the heading machine walks to a belt tail shield at the end of a tail runway of a main belt, the sensor is triggered to automatically cut off a power supply of the headlight to enable a driver to get a signal to timely stop running of a unit. The sensor is connected with a reset device, and when the heading machine is automatically power-off, the normal power supply function of the heading machine can be simply and quickly realized by the reset device. The anti-derail device realizes the automatic power off function of the heading machine, eliminates the safety hidden trouble, avoids frequent occurrence of derail accidents of a bridge type belt, no longer needs to arrange a specially-assigned person to care the bridge type belt, and can save the labor and reduce the investment.
Description
Technical field
The utility model relates to the anti-lost duct device of a kind of colliery elevating conveyor.
Background technology
Fully-mechanized digging machine is when operation; bridge-type belt is followed fully-mechanized digging machine and is moved on main belt runway; when running to forward main belt runway end lights position; if guardian can not pass on outage information in time; accident easily slides down; once the accident of sliding down will cause losses such as damaging main rotary drum of belt conveyer and bridge-type belt electric drum by pressure, causes very large impact to production, also bring very large economic loss simultaneously.
Summary of the invention
The purpose of this utility model is to prevent that elevating conveyor from sliding down, thereby provides a kind of development machine bridge conveyor anti-lost duct device.
For realizing above object, the utility model adopts following technical scheme.
The anti-lost duct device of development machine bridge conveyor, comprises the sensor that is fixed on elevating conveyor end, and sensor is connected with the headlight of development machine.When development machine is gone to the tail runway end lights belt tail guard shield of main belt, sensor is triggered, automatically cut off headlight power supply make development machine driver obtain signal can timely unit out of service.
As preferred version, described sensor connects resetting means, after development machine auto-breaking, by resetting means, can realize development machine normal power supply function, simple and fast.
The anti-lost duct device of development machine bridge conveyor described in the utility model, realized the automatic circuit break function of development machine, eliminate safe hidden trouble, avoided the slide down frequent generation of accident of bridge-type belt, greatly reduce the repair cost of fully-mechanized digging machine bridge-type belt and the time that drilling depth is produced in impact, be conducive to the normal structure of producing.Without arranging again special messenger to nurse bridge-type belt, realized labor saving, reduce the object dropping into, improved operating efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-elevating conveyor, 2-sensor, 3-development machine, 4-headlight, 5-resetting means, the main belt of 6-, 7-belt tail guard shield.
The specific embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, the utility model is done to further clear, complete explanation.
As shown in Figure 1, the anti-lost duct device of a kind of development machine bridge conveyor described in the utility model, comprises the sensor 2 that is fixed on elevating conveyor 1 end, and sensor 2 is connected with the headlight 4 of development machine 3.Sensor 2 is touch sensor or contactless biography device, and as touch sensor or infrared sensor, sensor 4 can be controlled headlight 4 power-off.When development machine 3 is gone to the tail runway end lights belt tail guard shield 7 of main belt 6, sensor 2 is triggered, automatically cut off headlight 4 power supplys make development machine 3 drivers obtain signal can timely unit out of service.
Sensor 2 connects resetting means 5, after development machine auto-breaking, by resetting means 5, can realize development machine normal power supply function.
The claimed scope of the utility model is not limited to the above specific embodiment; to those skilled in the art; the utility model can have various deformation and change, all any modifications of doing within design of the present utility model and principle, improves and is equal within replacement all should be included in protection domain of the present utility model.
Claims (2)
