Abstract
The utility model discloses a size-changeable superlong auxiliary arm device for a crane, which comprises a main arm, an auxiliary arm, a lifting hook and an overwinding device, wherein, the upper end of the main arm is connected with a diffraction frame type auxiliary arm, an energy storage cylinder support frame and a lifting pulley support frame; the upper end of the diffraction frame type auxiliary arm is provided with the overwinding device and a luffing dragline whose lower end is connected with the energy storage cylinder support frame and a luffing support frame dragline; the luffing support frame dragline is connected with the lifting pulley support frame; an energy storage cylinder is arranged between the middle part of the energy storage cylinder support frame and the lower part of the diffraction frame type auxiliary arm. The utility model has the advantages of simple structure and flexible operation. The utility model can make the crane exert the maximum effect without field limitation.
Description
The utility model relates to a kind of crane subsidiary arm, the adjustable overlength auxiliary of particularly a kind of amplitude.
Known crane subsidiary arm is mounted in crane arm side or below, during with the auxiliary hoisting operation auxiliary is captiveed joint with bolt device with principal arm, the angle between the two is that offset angle is a certain value, makes the auxiliary can't luffing, auxiliary is subjected to the effect of axial force and bending moment force, has limited the length of auxiliary.
But the later-model purpose of this reality is but that a kind of auxiliary also hoisting crane luffing overlength auxiliary device of luffing that can extend simultaneously will be provided.
The purpose of this utility model is achieved in that the upper end of principal arm is connected with the lower end of the posture auxiliary that spreads out simultaneously, one end of accumulation of energy jar support and an end of gin wheel support, the upper end of the posture of spreading out auxiliary was equipped with winding apparatus and luffing drag-line, the lower end of luffing drag-line is connected with luffing support drag-line one end with the other end of accumulation of energy jar support simultaneously, the other end of luffing support drag-line is connected with the other end of gin wheel support, pass through drag-line simultaneously, the luffing pulley, the luffing rope is connected with attic base, between the bottom of the middle part of accumulation of energy jar support and the posture auxiliary that spreads out the accumulation of energy cylinder is installed.
Owing to adopted such scheme, the posture of spreading out subframe can extend as required, because the structure of luffing support drag-line, gin wheel support, accumulation of energy jar support, accumulation of energy cylinder and the posture auxiliary that spreads out, making the posture auxiliary that spreads out can luffing be that its offset angle is a variable angle.But it is simple to be somebody's turn to do luffing overlength auxiliary apparatus structure, flexible during work, can not be subjected to the limitation in place, and hoisting crane is played a role to greatest extent.
Be further described in conjunction with the embodiments with reference to the accompanying drawings below.
But Fig. 1 hoisting crane luffing overlength auxiliary structure drawing of device.
But Fig. 2 hoisting crane luffing overlength auxiliary device luffing pulley A is to figure.
Spread out posture auxiliary, (3) lifting hook, (4) of (1) principal arm, (2) crossed winding apparatus, (5) luffing drag-line, (6) luffing support drag-line, (7) accumulation of energy jar support, (8) gin wheel support, (9) accumulation of energy cylinder, (10) gin wheel, (4) drag-line, (12) luffing pulley, (13) luffing rope, (14) derrick line among the figure.
Among Fig. 1, the lower end of principal arm (1) is connected with the chassis, the upper end of principal arm (1) is connected with an end of spread out posture auxiliary (2) lower end, accumulation of energy jar support (7), gin wheel support (8) simultaneously, winding apparatus (4) and luffing drag-line (5) were installed in the posture of spreading out auxiliary (2) upper end, and luffing drag-line (5) can change its length according to the length of the posture auxiliary (2) that spreads out.The below of crossing winding apparatus (4) is lifting hook (3), and the lower end of luffing drag-line (5) is connected with an end of the other end of accumulation of energy jar support (7), luffing support drag-line (6), and the other end of luffing support drag-line (6) is connected with the other end of gin wheel support (8); By drag-line (11) luffing pulley (12), luffing rope (13) connects simultaneously, and luffing rope (13) is wrapped on the luffing pulley, and the luffing pulley is connected with the chassis.At the middle part of accumulation of energy support (7) and spread out and be connected with accumulation of energy cylinder (9) between posture auxiliary (2) bottom, gin wheel (10) is installed at gin wheel support (8) middle part.During work, make the master file action receive (putting) derrick line (14), make secondary scrolling do to receive (putting) luffing rope (13) simultaneously, thereby realized hoisting action and corresponding derricking motion.
Claims (1)
1, but a kind of hoisting crane luffing overlength auxiliary device, mainly comprise principal arm, auxiliary, lifting hook, cross winding apparatus, it is characterized in that: the upper end while of principal arm and the lower end of the posture auxiliary that spreads out, one end of accumulation of energy jar support is connected with an end of gin wheel support, the upper end of the posture of spreading out auxiliary was installed winding apparatus and was connected with the luffing drag-line, the lower end of luffing drag-line is connected with the other end of accumulation of energy jar support and an end of luffing support drag-line simultaneously, the other end of luffing support drag-line is connected with the other end of gin wheel support, pass through drag-line simultaneously, the luffing pulley, the luffing rope is connected with attic base, and the accumulation of energy cylinder is installed between the bottom of the middle part of accumulation of energy jar support and the posture auxiliary that spreads out.
