Abstract
The utility model crane balance boom device, comprise mount pad and rotate around the hanging axis that fore-and-aft direction extends the equalizing bar be assemblied on mount pad, the two ends, left and right of described equalizing bar are equipped with hinge stent, the rotating shaft that the top of hinge stent is extended by fore-and-aft direction and equalizing bar hinged, the bearing pin that the bottom of hinge stent is extended by left and right directions is rotatably equipped with pulley.This crane balance boom device in use, two steel ropes are respectively around on the pulley of the correspondence of equalizing bar device, cause when occurring that the lineoutofservice signal pull of both sides is not of uniform size, because equalizing bar rotates with mount pad to assemble, the end of hinge stent and equalizing bar is hinged, the rotation direction of pulley is vertical with the rotation direction of equalizing bar, and steel rope both can swing along the length direction of equalizing bar, can broad ways swing again.More effectively can balance the pulling force of the steel rope of both sides, improve the stability that steel rope runs.
Description
Technical field
The utility model relates to elevator machinery field, is specifically related to a kind of crane balance boom device.
Background technology
Equilibrium arm is a kind of stressed mechanism of balance two wire rope ends that is used for, and is widely used in the machineries such as crane hoisting mechanism.The Chinese patent of notification number CN 202080827 U discloses a kind of overhead traveling crane equalizing bar weighing and force measurement overload alarm, this device comprises equalizing bar mounting seat, equalizing bar mounting seat is provided with equalizing bar by axle, equalizing bar two ends are installed and are connected with steel rope, hang steel rope swaying direction have limitation, this structure can only swing along equalizing bar length direction, if when steel rope needs to swing perpendicular to equalizing bar length direction, just cannot meet operating needs.
Summary of the invention
The purpose of this utility model is to provide a kind of crane balance boom device that steel rope can be made to swing along equalizing bar length direction, can swing along the Width of equalizing bar again.
To achieve these goals, the utility model adopts following technical scheme: crane balance boom device, comprise mount pad and rotate around the hanging axis that fore-and-aft direction extends the equalizing bar be assemblied on mount pad, the two ends, left and right of described equalizing bar are equipped with hinge stent, the rotating shaft that the top of hinge stent is extended by fore-and-aft direction and equalizing bar hinged, the bearing pin that the bottom of hinge stent is extended by left and right directions is rotatably equipped with pulley.
Be provided with self-lubricating bearing between described hanging axis and equalizing bar, self-lubricating bearing is sheathed on hanging axis.
Described mount pad top has the opening up mounting groove through along equalizing bar length direction, and the groove bottom wall of described mounting groove is provided with cushion, and described cushion has and supports with the lower surface of the equalizing bar being in heeling condition the bearing surface coordinated.
The beneficial effects of the utility model are: this crane balance boom device in use, two steel ropes are respectively around on the pulley of the correspondence of equalizing bar device, when crane lifting weight, occur that the lineoutofservice signal pull of both sides is not of uniform size to cause, when there is wire rope inclined-pulling in lifting process, because equalizing bar rotates with mount pad to assemble, the end of hinge stent and equalizing bar is hinged, the rotation direction of pulley is vertical with the rotation direction of equalizing bar, steel rope both can swing along the length direction of equalizing bar, can broad ways swing again.More effectively can balance the pulling force of the steel rope of both sides, reduce the wearing and tearing of steel rope, improve the stability that steel rope runs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model crane balance boom device;
Fig. 2 is the partial schematic diagram in Fig. 1.
Detailed description of the invention
The embodiment of the utility model crane balance boom device, as shown in Figure 1-2: comprise mount pad 1 and rotate around the hanging axis 3 that fore-and-aft direction extends the equalizing bar 2 be assemblied on mount pad 1, mount pad 1 top has the opening up mounting groove through along the length direction of equalizing bar, the groove bottom wall of mounting groove is provided with cushion 11, cushion 11 adopts quality of rubber materials, and cushion 11 has and supports with the lower surface of the equalizing bar 2 being in heeling condition the bearing surface coordinated.Be provided with self-lubricating bearing between hanging axis 3 and equalizing bar 2, self-lubricating bearing is sheathed on hanging axis 3, is provided with boss 10 in the middle part of the lower end of equalizing bar 2, and the left and right sides of boss 10 bottom is the inclined-plane 101 be obliquely installed relative to the bearing of trend of equalizing bar 2.When equalizing bar 2 is in heeling condition to the left or to the right, the inclined-plane of the corresponding side of boss 10 supports with cushion 11 and coordinates, and by arranging the inclined-plane 101 of boss 10, equalizing bar 2 is large with the area of contact of cushion 11, impulsive force during collision is less, and buffering effect is better.
The two ends, left and right of equalizing bar 2 are equipped with hinge stent 5, and the rotating shaft 6 that the top of hinge stent 5 is extended by fore-and-aft direction is hinged with equalizing bar 2, and the bearing pin 9 that the bottom of hinge stent 5 is extended by left and right directions is rotatably equipped with pulley 8.The both sides on the top of equalizing bar 2 are the relative inclined-plane 21 tilting upward extension, and the cross section along the bearing of trend of equalizing bar is echelon form.The two ends of hanging axis 3 are equipped with annular groove, are inserted in annular groove the axial limiting realized hanging axis 3 by baffle plate 4, and baffle plate 4 is bolted to connection on mount pad 1.The axial limiting mode of rotating shaft 6 is identical with the axial limiting mode of hanging axis.The end of bearing pin 9 is provided with semi-circular groove, and buckle 7 is plugged in semi-circular groove, to bearing pin 9 axis and radial direction spacing.
In use, two steel ropes are respectively around on the pulley 8 of the correspondence of equalizing bar device, when crane lifting weight, occur that the lineoutofservice signal pull of both sides is not of uniform size to cause, when there is wire rope inclined-pulling in lifting process, because equalizing bar rotates with mount pad to assemble, the end of hinge stent and equalizing bar is hinged, steel rope both can swing along the length direction of equalizing bar, can swing again along the Width perpendicular to length direction.More effectively can balance the pulling force of the steel rope of both sides, reduce the wearing and tearing of steel rope, improve the stability that steel rope runs.When equalizing bar swings in the lateral direction, when being in heeling condition, cushion 11 contact-impact of boss 10 meeting first and on mount pad 1 below equalizing bar 2, cushion 11 is quality of rubber materials, can buffer action be played, avoid equalizing bar directly and mount pad collide, and then weaken the vibration of steel rope.
In other embodiments, the axle sleeve between hanging axis and equalizing bar also can adopt alloy sheath, and alloy sheath is located at the outside of hanging axis, also can adopt self lubrication bearing.
In other embodiments, cushion also can adopt other soft material to make, as nylon etc.
In other embodiments, the below of equalizing bar does not arrange boss, and equalizing bar is when being in heeling condition, and the lower surface of equalizing bar directly supports with the cushion on mount pad and coordinates, and plays buffer action.
In other embodiments, for the mount pad not arranging mounting groove, and on equalizing bar, groove is offered, now, cushion can be located on the sidewall of mount pad, and the sidewall of mount pad is convexly equipped with boss, cushion is arranged on boss, and when equalizing bar tilts, the lower surface of equalizing bar supports with cushion and coordinates.
