Abstract
The utility model relates to the technical field of cable power supply, in particular to a cable slack on-line detection protector which comprises a supporting plate and roller wheels as well as a limit switch, wherein the roller wheels comprise fixed roller wheels and following roller wheels which are all arranged on the supporting plate, the following roller wheels are connected with a tension spring fixed on the supporting plate, provided with limit sheets, and positioned in a sliding groove on the supporting plate; and the fixed roller wheels are respectively distributed on a lead-in end and a lead-out end of the cable slack on-line detection protector. The cable slack on-line detection protector has the advantage that the real-time on-line detection on cable slack of a movable cable reel of a crane can be simply and effectively realized, thus realizing the function of preventing the cable from loosening or tightening overly. The cable slack on-line detection protector avoids the direct economic loss generated by broken cables and the loss caused by shut-down of the crane.
Description
Technical field
The utility model relates to the cable power supply technical field, is the online detection fender guard of a kind of cable degree of tightness specifically.
Background technology
At present, the complete machine of employed all kinds of rail mounted transfer cranes moves the power supply of the main employing of power supply cable drum removal cable on all kinds of railway goods yards and the staith.The removal cable reel that uses has two kinds now: 1, do not dispose cable degree of tightness fender guard; 2, disposed cable tension fender guard, but operating mode real-time online check cable tension force entirely, because existing fender guard is to bump limit switch by cable flexing, so, can only just can work swinging to maximum position.And can not realize measuring ability at regional area, when near cable access point, no matter cable stretch is much, cable all can not swing to maximum position.Such device does not have cable to cross lax the detection and defencive function simultaneously.
In sum; then the existing apparatus shortcoming is can not cross pine and tension by really real-time check cable when cable tension fender guard; cable is broken because of crossing tensioning in the course of the work; perhaps because of crossing lax being scattered on the big Car Track; thereby broken by big wheel; this type of accident occurs more in transfer crane uses; influencing hoisting crane on the one hand normally uses and shuts down; on the other hand; because cable is crushed suddenly or breaks by big wheel in orbit in power supply is used, thereby easily cause electric leakage to cause safety misadventure.
Summary of the invention
The utility model is intended to overcome the defective of above-mentioned prior art, provides a kind of cable degree of tightness online detection fender guard,
The purpose of this utility model realizes by following measure:
The online detection fender guard of a kind of cable degree of tightness; comprise stay bearing plate and roller; it is characterized in that: described roller is divided into fixed idler whell and follower rollers; described fixed idler whell and follower rollers are installed on the stay bearing plate; follower rollers links to each other with tension spring on being fixed on stay bearing plate, and described follower rollers is positioned at the sliding tray on the stay bearing plate.
Described follower rollers is provided with banking stop.
Also include limit switch.
Described limit switch is two.
Described fixed idler whell is distributed in cable degree of tightness online detection fender guard end of incoming cables and leading-out terminal respectively.
The utility model advantage is: cable stretch that can simple and effective realization hoisting crane removal cable reel obtains real-time online detection, thereby realizes that cable crosses the degree of tightness defencive function.Direct economic loss and the hoisting crane parking loss of avoiding cable to be produced by breaking.Can avoid cable to crush in orbit simultaneously or break causing electric leakage and the personal safety accident of appearance.Thereby can also avoid the cable stretch tension to prolong cable life.
Description of drawings
Fig. 1 is the utility model structural representation;
In the accompanying drawing 1, stay bearing plate 2, fixed idler whell 3, follower rollers 4, tension spring 5, sliding tray 6, banking stop 7, limit switch.
The specific embodiment
The online detection fender guard of a kind of cable degree of tightness; comprise stay bearing plate and roller; roller is divided into fixed idler whell and follower rollers; described fixed idler whell and follower rollers are installed on the stay bearing plate; follower rollers links to each other with tension spring on being fixed on stay bearing plate, and follower rollers is provided with banking stop, and described follower rollers is positioned at the sliding tray on the stay bearing plate; also include limit switch, fixed idler whell is distributed in cable degree of tightness online detection fender guard end of incoming cables and leading-out terminal respectively.
After cable is through the online detection fender guard of degree of tightness; pass through fixed idler whell successively; follower rollers; fixed idler whell; between fixed idler whell and follower rollers, be provided with simultaneously two limit switches; limit when detecting cable respectively and crossing pine or tension; because follower rollers is pressed on the cable by tension spring all the time; when cable stretch is big; spring stress is big; when cable stretch hour; spring stress is little; thereby slippage in the guide groove of follower rollers on stay bearing plate; banking stop on the follower rollers is along with the follower rollers side-to-side movement during to the set position of limit switch; a limit switch is sent out in the banking stop contact, and two limit switches can be realized the pine excessively or the tension protection of cable according to its detected maximin.Described limit switch is a prior art, can use touch switch.
