Abstract
The utility model belongs to the jack -up field especially relates to a hoist compensating beam with slack rope limit function who is used for the hoist, set up on the frame and be located the limit switch directly over the compensating beam roof beam body and set up the safe chi on the compensating beam roof beam body including setting up the compensating beam roof beam body on the frame and set up the wire rope who is used for hoisting the lifting hook on the compensating beam roof beam body, still including, by the upper end of safe chi is located limit switch, and can along with the compensating beam roof beam physically the rotation and contact limit switch, the one end of the compensating beam roof beam body is provided with the spring that draws high that links to each other with the frame, safe chi is located between extension spring and the limit switch, the utility model discloses a production efficiency and factor of safety have been mentioned to the function that the mechanical system realized avoiding wire rope to take off the groove, owing to make simply, the cost is lower simultaneously, have wide application prospect in the hoist field.
Description
Technical field
The utility model belongs to lifting field, particularly relates to a kind of crane balance beam with slack rope limit function for hoisting crane.
Background technology
Conventional crane, be lifted on suspension hook on equalizing bar in decline process, when suspension hook runs into some obstacle stopping whereabouts on aerial or ground, and now reel is also restricted toward whereabouts in continuation, looseness of steel wire ropes can be caused like this and take off groove, the lighter needs repeatedly to keep in repair, and severe one may bring potential safety hazard to production work.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of crane balance beam with slack rope limit function is provided, effectively can avoid the de-groove danger caused because of looseness of steel wire ropes, conveniently produce and improve safe handling coefficient, being applicable to all kinds hoisting crane.
The technical scheme that the utility model adopts: a kind of crane balance beam with slack rope limit function, comprise and be arranged at equalizing bar beam body on vehicle frame and be arranged on equalizing bar beam body for lifting the steel rope of suspension hook, it is characterized in that: also comprise and being arranged on vehicle frame and the limit switch be positioned at directly over equalizing bar beam body and the safety ruler be arranged on equalizing bar beam body, the upper end of described safety ruler is positioned at by limit switch, and can contact limit switch with the rotation of equalizing bar beam body; One end of described equalizing bar beam body be provided be connected with vehicle frame draw high spring, described safety ruler is between extension spring and limit switch.
Described equalizing bar beam body is arranged on vehicle frame by equalizing bar axle, and can rotate around equalizing bar axle.
Described limit switch is positioned at the left side of equalizing bar axle axis, described safety ruler and draw high the right side that spring is positioned at equalizing bar axle.
Described extension spring one end is connected with equalizing bar beam body, and the other end is connected with vehicle frame by spring supporting seat.
Described limit switch comprises the limit switch main body be arranged on vehicle frame and the feeler lever being arranged at limit switch body top.
Advantage of the present utility model: the utility model realizes the function avoiding steel cable slot disengaging mechanically, refer to production efficiency and safety factor, simultaneously simple owing to manufacturing, cost is lower, has broad application prospects in crane field.
Accompanying drawing explanation
Fig. 1 is constructional drawing of the present utility model.
Fig. 2 is the constructional drawing of limit switch in the utility model.
Detailed description of the invention
As Fig. 1, shown in 2, a kind of crane balance beam with slack rope limit function, comprise the equalizing bar beam body 6 be installed on by equalizing bar axle 8 on vehicle frame 9, equalizing bar beam body can rotate around equalizing bar axle, equalizing bar beam body is provided with the steel rope 7 for lifting suspension hook, position vehicle frame is positioned at above equalizing bar beam body is provided with limit switch 1, limit switch 1 comprises the limit switch main body 10 be arranged on vehicle frame and the feeler lever 11 be movably arranged in limit switch main body 10, limit switch is positioned at the left side of equalizing bar axle, the right side that equalizing bar beam body is positioned at equalizing bar axle is also provided with safety ruler 2, safety ruler 2 can rotate with equalizing bar beam body, and can contact with the feeler lever of limit switch after turning, also by pull bar 5, an extension spring 3 is installed at the right-hand member of equalizing bar beam body, the other end drawing high spring 3 is connected on vehicle frame by spring supporting seat 4, spring supporting seat is fixed on vehicle frame.
Principle of work: spring supporting seat 4 is fixed on vehicle frame, extension spring 3 one end is fixed on spring supporting seat 4, the other end is connected with equalizing bar beam body 6, in suspension hook decline process, when suspension hook runs into some obstacle stopping whereabouts on aerial or ground, steel rope 7 loosens, extension spring 3 pulls equalizing bar beam body 6 to rotate certain angle, safety ruler 2 and limit switch 1 is collided, causes hoist power-cut, reel stops continuing lower rope, thus avoids the danger that steel rope 7 takes off groove.
Claims (5)
1. one kind has the crane balance beam of slack rope limit function, comprise and be arranged at equalizing bar beam body on vehicle frame and be arranged on equalizing bar beam body for lifting the steel rope of suspension hook, it is characterized in that: also comprise and being arranged on vehicle frame and the limit switch be positioned at directly over equalizing bar beam body and the safety ruler be arranged on equalizing bar beam body, the upper end of described safety ruler is positioned at by limit switch, and can contact limit switch with the rotation of equalizing bar beam body; One end of described equalizing bar beam body be provided be connected with vehicle frame draw high spring, described safety ruler is between extension spring and limit switch.
2. the crane balance beam with slack rope limit function according to claim 1, is characterized in that: described equalizing bar beam body is arranged on vehicle frame by equalizing bar axle, and can rotate around equalizing bar axle.
