Description
Technical field
The utility model belongs to the underground equipment security fields, relates in particular to a kind of monkey car wire rope breaking fender guard.
Background technology
The coal mine sloping lane overhead manned equipment is commonly called as " monkey car ", is applied to the colliery inclined shaft usually and takes advantage of the people, is that the most frequently used personnel in the pit transports equipment, belongs to endless-rope system, mainly is grouped into by drive part, tensioning portion, circuit pack and electric control part.At present; the protection of " monkey car " safe in operation has the rope of falling protection; the reminder alarm of getting on or off the bus protection; steel rope slipping protection etc.; but " monkey car " rope broken protector is not arranged as yet; in " monkey car " operational process; if " monkey car " steel rope is once disconnected rope; steel rope will glide under the effect of oblique sliding force; whole " monkey car " superior support personnel are along with gliding or dropping; can cause personal casualty and transportation facilities to damage, the use of inclined gallery " monkey car " steel rope at present is very lack of standardization, particularly in the inspection with steel rope; maintenance and periodic replacement aspect do not have the legal principle foundation; the mine that has is selected the high steel rope of tensile strength for use; the mine that has uses and selects the low steel rope of tensile strength for use, and each mine more time of change steel rope also lack of standardization, all be to change in two to four years one by rule of thumb.Bring very big potential safety hazard for like this inclined shaft " monkey car " transportation, therefore, it is extremely urgent that inclined gallery " monkey car " installs the wire rope breaking fender guard.
Summary of the invention
The purpose of this utility model provides a kind of monkey car wire rope breaking fender guard, solves existing monkey truck system and lacks rope broken protector, causes the operation of monkey car to have the problem of potential safety hazard.
For addressing the above problem; the technical solution of the utility model is: a kind of monkey car wire rope breaking fender guard; comprise the monkey truck system; return sheave crossbeam at the monkey truck system is equipped with support; an automatically controlled valve body is installed on the support; a spool that has lockhole is movably arranged in the automatically controlled valve body; the bottom of spool is fixedly connected with claw; described claw is provided be used to the groove that is stuck on the steel rope; automatically controlled valve body is provided with an electromagnetic lock; the dead bolt of electromagnetic lock and the lockhole on the spool are complementary, and a control system is connected with described electromagnetic lock circuit, are used for the open and close of control electromagnetic lock.
Between described spool and automatically controlled valve body, be provided with pressure spring.
Be provided with slide rail in described automatically controlled valve body, spool is installed in the automatically controlled valve body by slide rail.
Described control system comprises:
A travel switch is installed in monkey car tail take-up device place, is used for sending the slack rope signal;
A slack rope relay is connected with the travel switch circuit, receives the slack rope signal, and the open contact of described slack rope relay connects automatically controlled valve body, is used for the electromagnetic lock on the automatically controlled valve body of control, and normally closed contact is connected with main motor, is used for the main motor of control and shuts down.
Described control system also comprises an annunciator, and described annunciator is connected with the slack rope relay circuit, is used for sending alerting signal.
During use; actual installation situation according to the monkey car; the claw of some is installed near monkey car steel rope; when fracture takes place in monkey car steel rope; the travel switch that is installed in monkey car tail take-up device place is touched by steel rope; send the slack rope signal to the slack rope relay; the slack rope relay receives that the electromagnetic lock on the automatically controlled valve body of control is opened behind the signal; the claw of captiveing joint with spool is fallen; the slack rope relay stops the operation of monkey car owner motor and notice alarm equipment alarm simultaneously; fall behind under the claw; the claw groove carries out spacing to steel rope; when taking advantage of people's chair lift to arrive the claw place, take advantage of people's chair lift rope clamping device to be caught on by claw, make steel rope can not continue to glide, play protection discrepancy well personnel's safety effect.After eliminating fault, the control electromagnetic lock restores electricity, and manually claw is thrown off and takes advantage of people's chair lift rope clamping device, spool is boosted again, and claw leaves monkey car steel rope, and inclined gallery monkey car can recover normal condition.
The utlity model has following advantage: 1 is simple in structure, and 2 with low cost being easy to are transformed on the basis of existing installation, and 3 anti-break ropes are effective, improved the safety of monkey car greatly; 3 owing to adopt electric-control system, can close monkey car owner motor at once and stop the operation of monkey car behind disconnected rope, and the monkey car has been played protective effect.
