Abstract
The utility model discloses a power failure device in disengagement of a steel wire rope of a gantry crane, which is mainly used for solving the problem that the disengagement of the steel wire rope of the gantry crane can not be found out in time and cause damage to the steel wire rope. According to the technical scheme, the power failure device comprises a steel wire rope reel, and is characterized in that a support frame is arranged at the lower part of the steel wire rope reel and provided with stroke switches, the stroke switches are electrically connected with a motor control device of the steel wire rope reel, a limiting pressure plate is arranged at the upper part of the support frame, and return springs are arranged between the limiting pressure plate and the support frame. According to the power failure device, power failure can be conducted in the first time when the steel wire rope extends out of a normal position so as to stop the steel wire rope reel from rotating; and simultaneously an alarm is given out so as to remind a driver of checking the condition of the steel wire rope, the disengagement fault of the steel wire rope is controlled in a bud, thereby avoiding serious damage accidents of the steel wire rope. Shown by trial use, the power failure device is sensitive in response and obvious in effect, effectively plays a role in protecting the steel wire rope, prevents the damage to the loosen steel wire rope, and ensures the use safety and service life of the steel wire rope.
Description
Technical field
The utility model relates to a kind of elevator machinery, especially for high pedestal jib crane steel cable slot disengaging breaker device, belongs to the weight-lifting equipment technical field.
Background technology
High pedestal jib crane (be called for short door a machine) be a kind of with crane span structure by the crane span structure type hoisting crane of both sides outrigger support on ground rail or ground, it is port and pier weight-lifting equipment commonly used.The chief component of high pedestal jib crane comprise hoist, revolution, luffing and operating unit, wherein cable drum is the vitals of luffing mechanism.Cable drum the steel cable slot disengaging phenomenon can occur in the course of the work, and this is a kind of comparatively serious breakdown of equipment, is in time disposed in case steel cable slot disengaging occurs to cause easily serious accident.Some machine dependency structure design defect, taking off the groove fault can frequent occurrence.Such as certain shipbuilding enterprise, a high pedestal jib crane is because the design defect of luffing mechanism causes variable-amplitude steel wire rope often to take off groove, and this machine place in operation 2 years causes steel rope to be scrapped once because taking off the groove fault, expends a large amount of manpower and materials and repairs nearly ten times.For preventing steel cable slot disengaging, sometimes need to join the extension weight to keep operation at the gib head of hoisting crane.Above-mentioned situation has had a strong impact on equipment work efficiency and service life of steel wire rope.
The utility model content
The utility model is used for solving the defective of above-mentioned prior art, and a kind of door machine steel cable slot disengaging breaker device that can in time find steel cable slot disengaging and control the cable drum stall is provided.
The alleged problem of the utility model solves with following technical proposals:
A kind of machine steel cable slot disengaging breaker device, it comprises cable drum, special feature is: the bottom of described cable drum is provided with bracing frame, bracing frame is provided with travel switch, travel switch is electrically connected with cable drum electric machine control device, support frame as described above top is provided with spacing pressing plate, is provided with pull back spring between spacing pressing plate and the bracing frame.
Above-mentioned door machine steel cable slot disengaging breaker device, described device also is provided with annunciator, and annunciator is electrically connected with travel switch.
Above-mentioned door machine steel cable slot disengaging breaker device, the length of described spacing pressing plate and cable drum usable length coupling, described travel switch arranges 6-8, and they are distributed on the top of bracing frame.
Above-mentioned door machine steel cable slot disengaging breaker device, a uniform 6-10 pull back spring between described spacing pressing plate and the bracing frame.
The utility model needs timely handling problems to design a kind of machine steel cable slot disengaging breaker device for high pedestal jib crane steel cable slot disengaging fault, this device is installed in the cable drum bottom, when leaning out the normal position, touches steel rope spacing pressing plate, and then push down limit switch, outage stops operating cable drum; Give the alarm to driver's cab in the cable drum stall, the prompting driver checks the steel rope situation, and the steel cable slot disengaging Fault Control in bud, is avoided causing serious steel rope damage accident.Show that through on probation the utility model is quick on the draw, successful, effectively play the effect of protection steel rope, prevent the further destruction to the release, wire rope, ensured use safety and the service life of steel rope.
Description of drawings
Fig. 1 is the utility model structural representation.
Each parts label is expressed as follows among the figure: 1. bracing frame, 2. travel switch; 3. pull back spring; 4. spacing pressing plate; 5. cable drum; 6. annunciator; 7. operator's compartment.
The specific embodiment
Referring to Fig. 1, the utility model consists of and to comprise and be fixed with bracing frame 1 in the bottom of cable drum 5 by cable drum 5, and bracing frame is provided with travel switch 2, and travel switch is electrically connected with cable drum electric machine control device; Be provided with spacing pressing plate 4 on bracing frame top, the position of spacing pressing plate is corresponding with the contact of travel switch, and the upper surface of spacing pressing plate and the spacing of cable drum are less than the diameter of steel rope.For guaranteeing the sensitieness of travel switch action, prevent bias voltage, travel switch arranges 6-8, and they are distributed on the top of bracing frame; The usable length size of the length of spacing pressing plate 4 and cable drum is complementary, and is connected by pull back spring 3 between spacing pressing plate and the bracing frame, and pull back spring is 6-10, and they are distributed between spacing pressing plate and the bracing frame.Described device also is provided with annunciator 6, and annunciator is electrically connected with travel switch, and annunciator is installed in the operator's compartment 7 of gantry crane.
Still referring to Fig. 1, when the utility model uses, in case the steel rope bracket occurs, the position that leans out of steel rope presses spacing pressing plate 4, and the elastic force that spacing pressing plate overcomes pull back spring 3 moves down, and touches the contact of travel switch 2, the cable drum motor is closed in the travel switch action, makes the cable drum stall; Travel switch triggers the annunciator 6 that is arranged in the operator's compartment 7 simultaneously, and annunciator sends alarm signal, and notice gantry crane driver in time processes the steel rope of bracket, and fault namely is resolved in bud, avoids steel rope to damage because getting loose.After return was processed at the bracket position of steel rope, spacing pressing plate was returned to the normal position under the effect of pull back spring.
