The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Referring to FIG. 1 and FIG. 2, a kind of bridge crane cart cable protecting device of the utility model include controller, locking frame 1,
Elastomeric element 3, loose cable limit switch 4.Bridge crane includes leading cable frame 2, cable drum.Locking frame 1, which is placed horizontally at, leads the upper of cable frame 2
Side；The top for leading cable frame 2 is provided with mounting portion 201 for connecting elastomeric element 3；Locking frame 1 passes through elastomeric element 3 and installation
Portion 201 connects.Cable 8 enters after locking frame 1 leads cable frame 2 and guides cable 8 mobile by leading cable frame 2.Loose cable limit is opened
Close 4 with to lead 2 position of cable frame relatively fixed, and connect with controller, for detecting whether locking frame 1 is displaced, reception due to
The loose cable signal that the loose cable limit switch 4 of the displacement triggering of locking frame 1 is generated and exported, controller is according to loose cable signal control bridge
It hangs out of service.That is, extra cable 8 rides on locking frame 1, oppresses locking frame 1 and overcomes elasticity when the loose cable of cable 8 occurs
The elastic force of component 3 generates displacement, changes the positional relationship of itself and loose cable limit switch 4, triggers loose cable limit switch 4 and exports loose cable
Signal, control bridge crane is out of service after controller receives loose cable signal, prevents loose cable excessive damage cable 8, causes bridge crane failure；
The reliability and safety for improving bridge crane operation, protects the property safety and personnel safety of operation field.
A kind of bridge crane of the utility model, including leading cable frame 2, cable drum and above-mentioned bridge crane cart cable protection dress
It sets, again may be by bridge crane cart cable protecting device prevents loose cable from excessively damaging cable 8, causes bridge crane failure；It improves
The reliability and safety of bridge crane operation protects the property safety and personnel safety of operation field.
Below by specific embodiment, concrete structure design and working principle to the utility model are explained in detail
It states.
In one embodiment, referring to FIG. 1 and FIG. 2, locking frame 1 is rectangle frame；Elastomeric element 3 is helical spring.Bridge crane is big
Vehicle cable protecting device further includes bolt assembly comprising bolt 5, nut 6 and gasket 7.It is useful in the top setting for leading cable frame 2
In the mounting portion 201 connecting with elastomeric element 3, the through-hole that adaptation is connect with bolt 5 is provided on mounting portion 201；Correspondingly,
The position that each through-hole is corresponded on locking frame 1 is provided with corresponding through-hole 101 concentric with each through-hole respectively.Bolt 5 sequentially passes through
It is connect after through-hole, helical spring, gasket 7, corresponding through-hole 101 with nut 6, the supporting role for making locking frame 1 pass through helical spring
The elastic force of helical spring can be overcome to generate shifting positioned at the top for leading cable frame 2, and if applying enough oppressive forces above locking frame 1
Position.Bolt 5 can then limit the direction of displacement and amplitude of locking frame 1, and be unlikely to the unevenness for making helical spring due to locking frame 1
Even stress and damage.In order to guarantee the smooth displacement when suffering oppression power of locking frame 1, the diameter of corresponding through-hole 101 is greater than bolt 5
Diameter, in order to guarantee the normal work of helical spring, the aperture of gasket 7 need to be less than the diameter of corresponding through-hole 101.Certainly, corresponding
Through-hole 101 is also possible to the long slot hole of left and right directions, as long as being able to achieve the smooth displacement of locking frame 1, i.e., in the guarantor of the utility model
Within the scope of shield.In addition, locking frame 1 is rectangle frame, then corresponds to through-hole 101 and be preferably provided on the quadrangle of locking frame 1, and through-hole
Then it is arranged on the quadrangle of the corresponding through-hole 101 of mounting portion 201.

4, be separately positioned on the left and right side of locking frame 1, and after left loose cable limit switch 4 is connected with right loose cable limit switch 4 and
Controller connection, extra cable 8 rides over any side of locking frame 1 when no matter loose cable occurs, and triggers left loose cable limit switch 4
Or right loose cable limit switch 4 can export loose cable signal to controller, keep controller control bridge crane out of service.
In one embodiment, loose cable limit switch 4 is close switch, and is fixed on and leads on cable frame 2, is not having loose cable
When keep it is relatively fixed with the position of locking frame 1.Controller is PLC, the switch value input interface of loose cable limit switch 4 and PLC
Connection.When loose cable occurs, the elastic force that extra cable 8 oppresses locking frame 1 and locking frame 1 is made to overcome elastomeric element 3 generates displacement,
It triggers loose cable limit switch 4 and exports loose cable signal, loose cable signal is on-off model, and PLC is according to receiving above-mentioned switching value
It is out of service that signal controls bridge crane.
In one embodiment, referring to Fig.1, bridge crane cart cable protecting device further includes direction selection limit switch, tension
Limit switch, rocker arm 11, guide rod 9, target.Direction selection limit switch, tension limit switch, target are respectively positioned on limit case 10
Interior, limit case 10 is fixedly connected with cart.Direction selection limit switch and tension limit switch are all made of close to switch.Rocker arm 11
It is connect with guide rod 9, guide rod 9 is connect with target.Direction limit switch includes rotating forward limit, reversion limit；Tension limit switch packet
It includes and rotates forward tension limit, reversion tension limit.Rocker arm 11 is used to adjust the extending direction of cable 8 according to the traffic direction of cart.
When rocker arm 11, which is located at diagram, leads cable 2 left side of frame, i.e., cart is driving target triggering just by guide rod 9 to when illustrating race running
Turn limit switch or reversion limit switch export rotating forward perhaps reverse signal to controller controller according to rotate forward or invert
Signal controls cable drum and rotates forward or invert；When rocker arm 11, which is located at diagram, leads cable 2 right side of frame, i.e., cart is transported to diagram left side
When row, target triggering reversion limit switch is driven by guide rod 9 or rotates forward limit switch output reverse signal or positive transfering the letter
Number give controller, controller according to reverse signal or positive rotaring signal control cable drum reversion or rotate forward.When rocker arm 11 by
In cable tension pull rocker arm 11 be located at lead cable frame 2 left side or right side tension position when, guide rod 9 drive target touching
Hair rotates forward tension limit switch or reversion tension limit switch exports tension signal to controller, and controller is according to tension signal
It is out of service to control bridge crane, cable 8 is prevented to be pulled off.
Preferably, it is connect after tension limit switch is connected with loose cable limit switch 4 with controller, as long as triggering tension limit
Any one in any one or loose cable limit switch 4 in switch, controller will all receive on-off model, then control
Device is out of service according to the on-off model control bridge crane received.
In with specific example, bridge crane cart cable protecting device further includes take-up key, is connect with controller, when
Extra cable is restored to normal condition for controlling cable drum when confirmation occurs without other abnormal conditions when loose cable occurs.
