Description
Technical field
This utility model, is specifically related to a kind of coal-cutting machine towline protecting apparatus.
Background technology
Currently used coal-winning machine had towing cable protection device originally at the use initial stage, but in use owing to making
The trailing weight causing coal-winning machine with domestic cable and cable protecting clamp increases, and protection device frequent movement causes coal-winning machine
Cisco unity malfunction, therefore can only shield original defencive function.Damage due to towing cable protective folder during the use in later stage
Badly cause electric cable for coal mining machine play snap joint often to pull, electrical equipment accident occurs.
Utility model content
The purpose of this utility model is to provide a kind of coal-cutting machine towline protecting apparatus, to overcome above-mentioned prior art to exist
Defect, this utility model reduces the incidence rate of electrical equipment accident, it is ensured that equipment properly functioning.
For reaching above-mentioned purpose, this utility model adopts the following technical scheme that
A kind of coal-cutting machine towline protecting apparatus, including pullswitch, pullswitch is fixed on and electric cable for coal mining machine play side
To parallel position, one end of pullswitch is fixed with a retainer ring, and the other end is holding wire access port, and retainer ring is by drawing
Line is connected to the pipe collar being fixed on electric cable for coal mining machine, and holding wire access port is connected to coal-winning machine by holding wire.
Further, pullswitch is that KHJ15/18-1 type combines jerk latch switch.
Further, pullswitch is provided with two bolts hole.
Further, pullswitch by two coordinate with bolt hole be bolted to and electric cable for coal mining machine play direction
Parallel position.
Further, retainer ring is fixed by welding in one end of pullswitch.
Further, bracing wire is steel wire rope.
Compared with prior art, this utility model has a following useful technique effect:
This utility model changes protection device into pullswitch, drives stay cord action when cable generation play, and bracing wire is opened
Pass realizes automatic blocking, and coal-winning machine is automatically stopped traction and shows fault message on a display screen after receiving block signal, logical
Cross this utility model and decrease the incidence rate of electrical equipment accident, it is ensured that equipment properly functioning.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail:
Seeing Fig. 1 and Fig. 2, a kind of coal-cutting machine towline protecting apparatus, including pullswitch 8, pullswitch 8 is KHJ15/
18-1 type combination jerk latch switch, pullswitch 8 is provided with two bolts hole, and pullswitch 8 is joined with bolt hole by two
That closes is bolted to the position parallel with electric cable for coal mining machine 6 play direction, and one end of pullswitch 8 is welded with a retainer ring
1, the other end is holding wire access port 2, and retainer ring 1 is connected to the pipe collar 3 being fixed on electric cable for coal mining machine 6, bracing wire by bracing wire 4
4 is steel wire rope, and holding wire access port 2 is connected to coal-winning machine by holding wire 5, and electric cable for coal mining machine 6 one end is connected with coal-winning machine, separately
One end is connected with cable connector 7.
Below in conjunction with the accompanying drawings implementation process of the present utility model is further described:
This utility model uses the KHJ15/18-1 type combination jerk latch switch that a Tianjin Huaning produces, in its one end
The retainer ring 1 of one connecting steel wire ropes bracing wire 4 of welding, the other end installs the holding wire access port 2 adapted with holding wire 5.Will
Jerk latch switch is bolted to the position parallel with electric cable for coal mining machine 6 play direction, at coal-winning machine with two M12*30's
The pipe collar 3 adapted with cable size is installed on cable 6 and is connected with the retainer ring 1 on jerk latch switch with bracing wire 4, when
Electric cable for coal mining machine 6 occurs to drive bracing wire 4 action during play, and jerk latch switch realizes automatic blocking, and coal-winning machine receives locking
It is automatically stopped traction after signal and shows fault message on a display screen.
