Abstract
The utility model provides a balancing lever of a double-single-connection roller hoisting mechanism and relates to a main hoisting mechanism of a crane. The balancing lever of the double-single-connection roller hoisting mechanism solves the problem that an existing balancing lever can not be used in the double-single-connection roller hoisting mechanism and comprises a single-connection roller I, a single-connection roller II and a steel wire rope wound around a fixed pulley set, a movable pulley set and balance pulleys from the two single-connection rollers. The steel wire rope is wound around the middle portions of the two balance pulleys and then connected with a balancing lever body. The balancing lever body comprises a support fixed to a trolley frame, a balancing pull board connected with the support through a hinge pin and a wedge-shaped joint connected with the balancing pull board through a hinged shaft. A sliding groove is formed in the balancing pull board. The hinge pin is installed in the sliding groove and is capable of sliding laterally. The balancing lever of the double-single-connection roller hoisting mechanism is used for casting of the main hoisting mechanism of the crane and has the advantages that the hoisting mechanism is safe and reliable and the steel wire rope is convenient to adjust.
Description
Technical field
The utility model relates to main hoisting mechanism of crane, particularly the two single-joint winding drum hoisting mechanism compensating bars of a kind of employing.
Background technology
Existing main hoisting mechanism of crane is as shown in Figure 1: lifting mechanism adopts two simply connected reels 1 and 2, and steel rope 4 is walked around fixed pulley group 5, running block 6 is realized balance by equalizer pulley 3.The deficiencies in the prior art part is to realize balance by pulley, can only use steel cable, adjusts inconvenience, and poor stability, particularly can't meet the requirement that does not allow to adopt the pulley balance in main lifting mechanism of foundry crane.
Usually use a kind of compensating bar in the lifting mechanism of double crosslinking drum, its structure as shown in Figure 3.Because lever can not be oversize, the permission stroke can not be too large, therefore can only be used in the lifting mechanism of double crosslinking drum.High when the hoisting speed of crane requirement, when structural arrangement need to adopt two simply connected reel, for safety, need to adopt compensating bar.The compensating bar of prior art can't be used in two single-joint winding drum hoisting mechanisms.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, and the compensating bar of a kind of pair of single-joint winding drum hoisting mechanism is provided, and solves the technical matters that existing compensating bar can't be used in two single-joint winding drum hoisting mechanisms.
The utility model is achieved through the following technical solutions:
The compensating bar of a kind of pair of single-joint winding drum hoisting mechanism, comprise: I simply connected reel and II simply connected reel, and the steel rope of walking around fixed pulley group, running block, equalizer pulley from two simply connected reels, it is characterized in that: described steel rope connects compensating bar at the middle part of walking around two equalizer pulleys, and described compensating bar comprises: be fixed on the bearing on trolley frame, the balance arm-tie be connected by bearing pin with bearing, with the balance arm-tie by the wedge joint of stud connection and be connected wedge joint and the rope clamp of steel rope; Described balance arm-tie has chute, and described bearing pin is arranged in chute and can horizontally slips.
In described bearing pin both sides, baffle plate is set, at pin shaft end, axle end baffle plate is set.
The utility model compared with prior art, because the middle part of walking around two equalizer pulleys at steel rope connects compensating bar, the balance arm-tie of compensating bar has chute, bearing pin is arranged in chute and can horizontally slips, compensating bar can be moved in the horizontal direction with respect to trolley frame, be used for balance because of the overbalance of installing and the device fabrication error causes.Because compensating bar is located at the middle part of two cover mechanisms, make steel rope become two, the installation of steel rope and the horizontal adjustment of suspender are more convenient.
The utility model is for main lifting mechanism of foundry crane, has a lifting mechanism safe and reliable, the advantage that steel rope is easy to adjust.

The specific embodiment
As shown in Fig. 2,4,5,6, the compensating bar of a kind of pair of single-joint winding drum hoisting mechanism comprises: I simply connected reel 1 and II simply connected reel 2, and the steel rope 4 of walking around fixed pulley group 5, running block 6, equalizer pulley 3 from two simply connected reels; Described steel rope 4 connects compensating bar 7 at the middle part of walking around two equalizer pulleys 3, and described compensating bar 7 comprises: the rope clamp 7-6 that is fixed on the bearing 7-1 on trolley frame, the balance arm-tie 7-3 be connected by bearing pin 7-2 with bearing 7-1, the wedge joint 7-5 be connected by hinge 7-4 with balance arm-tie 7-3 and connects wedge joint 7-5 and steel rope 4; Described balance arm-tie 7-3 has chute 7-3-1, and described bearing pin 7-2 is arranged in chute 7-3-1 and can horizontally slips.
In described bearing pin 7-2 both sides, baffle plate 7-7 is set, is used for preventing rotating and axial motion; At bearing pin 7-2 axle head, axle end baffle plate 7-8 is set, is used for the longitudinal travel of limiting balance arm-tie along bearing pin.
Compensating bar of the present utility model is located at the middle part of two cover mechanisms, is used for balance because of the overbalance of installing and the device fabrication error causes.The utility model has fixed bearing, bearing pin for the limiting balance amount, compensating bar can move in the horizontal direction, and meets the balance of mechanism requirement, and it has following advantage: steel rope becomes two, the installation of steel rope and the horizontal adjustment of suspender are more convenient, and lifting mechanism safety and reliability are higher.
