Abstract
The invention discloses a kind of crane hoisting mechanism, belong to the hoisting crane technical field, mainly comprise reel and fixed pulley group, described reel rotates by two bearing seats and is installed on the upper surface of described vehicle frame, the fixed pulley group is by rope connecting shackle assembly, one end of rope is fixed on the reel, and described lifting mechanism also comprises the pulley beam that is used to install described fixed pulley group, and described pulley beam is installed on the upper surface of described vehicle frame.The present invention makes the fixed pulley group be convenient to safeguard by changing the installation site of fixed pulley group, has improved the hoisting depth of weight simultaneously.
Description
Technical field
The present invention relates to the hoisting crane technical field, relate in particular to a kind of crane hoisting mechanism.
Background technology
All rely on lifting mechanism by the rope connecting shackle weight of slinging during hoisting crane lifting weight, traditional lifting mechanism comprises the reel on the vehicle frame that is installed in walking dolly and rotates the fixed pulley group that is installed on the vehicle frame, wherein the installation site of fixed pulley group is positioned on the vehicle frame of reel below, though this structure makes the hoisting crane compact overall structure, but, there is following shortcoming:
1, time-consuming, effort during maintenance fixed pulley group because the fixed pulley group is positioned at the below of reel, is subjected to space constraint, as will safeguarding or change very difficulty of assembly pulley, even will dismantle parts such as reel, increases workman's work capacity;
2, the weight hoisting depth is limited, the weight hoisting depth is subjected to the restriction of fixed pulley group position height, because the fixed pulley group is positioned on the cross member of frame of reel below, so weight can only the highlyest be promoted to the cross member of frame below apart from fixed pulley group half meter height and position nearly;
When 3, lifting weight, the fixed pulley group is subjected to oblique pulling, can cause the vehicle frame fatigue of walking dolly impaired, influences the normal operation of hoisting crane.
Summary of the invention
Technical matters to be solved by this invention is: a kind of crane hoisting mechanism is provided, by changing the installation site of fixed pulley group, makes the fixed pulley group be convenient to safeguard, improved the hoisting depth of weight simultaneously.
For solving the problems of the technologies described above, technical scheme of the present invention is: crane hoisting mechanism comprises and rotates the reel that is installed on the vehicle frame that described reel is installed on the upper surface of described vehicle frame by bearing seat; Be used for fixed pulley group by rope connecting shackle assembly; Described lifting mechanism also comprises the pulley beam that is used to install described fixed pulley group, and described pulley beam is installed on the upper surface of described vehicle frame.
As a kind of improvement, described pulley beam is articulated on the described vehicle frame.
As further improvement, the two ends of described reel are equipped with the rotating shaft that is fixed together with described reel, and described reel is installed on the described vehicle frame by two bearing seats, and pairing bearing seat is stretched out in the rotating shaft of the power intake of described reel.
After having adopted technique scheme, the invention has the beneficial effects as follows: because the fixed pulley group is installed on the pulley beam, and the pulley beam is installed on the upper surface of vehicle frame, make the installation site of fixed pulley group transfer to the vehicle frame upper surface of walking dolly from the below of reel, it is big that installing space becomes, maintenance and easy to maintenance; Because the position on vehicle frame of fixed pulley group is improved, make also corresponding being improved of hoisting depth of weight, compare with traditional lifting mechanism, do not changing under other conditions, the hoisting depth of weight has improved half meter nearly, is equivalent to the height of vehicle frame, if on traditional crane hoisting mechanism, will reach this effect, remove the height of leaveing no choice but change factory building, the position of hoisting crane walking dolly is improved half meter, can realize.
Because the pulley beam is articulated on the vehicle frame of walking dolly, when the fixed pulley group because tiltedly the drawing when stressed of rope, the pulley beam can rotate an angle around jointed shaft, make the oblique pulling that acts on the fixed pulley group become the positive pressure that acts on the pulley beam, improve the force-bearing situation of walking dolly vehicle frame, prolonged the service life of crane hoisting mechanism.
Because reel rotates by two bearing seats and is installed on the vehicle frame, make reel can rely on the output shaft of reductor to support, thereby when maintenance or replacing reductor, needn't dismantle reel, compare with traditional lifting mechanism, traditional reel is a cantilevered, one end is installed on the vehicle frame by bearing seat, and the output shaft direct connection of the other end and reductor is when safeguarding reductor, reel need be disassembled together, therefore increase a lot of labor contents; And adopt the mounting means of two bearing seats with the hinged support of reel, can dismantle reductor easily and do not influence the stressed of reel.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the embodiment of the invention;
Fig. 2 is the plan structure scheme drawing of Fig. 1;
Among the figure: 1, vehicle frame, 2, reel, 3, the fixed pulley group, 31, fixed pulley, 4, hook assembly, 5, the pulley beam, 6, rope, 7, bearing seat, 8, pulley beam bearing seat.
The specific embodiment
As depicted in figs. 1 and 2, a kind of crane hoisting mechanism, mainly comprise reel 2 and fixed pulley group 3, described reel 2 rotates and is installed on the upper surface of described vehicle frame 1, fixed pulley group 3 is by rope 6 connecting shackle assemblies 4, one end of rope 6 is fixed on the reel 2, the other end is fixed on the fixed pulley group 3, rope 6 is wound between the running block of fixed pulley group 3 and hook assembly 4, under the power driven of reductor, reel 2 rotates, and rope 6 is reeled on reel 2, and hook assembly 4 drives weight and rises.Described lifting mechanism also comprises the pulley beam 5 that is used to install described fixed pulley group 3, the fixed pulley 31 of described fixed pulley group 3 all rotates and is installed on the described pulley beam 5, described pulley beam 5 is installed on the upper surface of described vehicle frame 1, described pulley beam 5 is articulated on the described vehicle frame 1 by two pulley beam bearing seats 8, when fixed pulley group 3 because tiltedly the drawing when stressed of rope 6, pulley beam 5 can be swung an angle, automatic capturing, make the oblique pulling that acts on the fixed pulley group 3 become the positive pressure that acts on the pulley beam 5, improve the force-bearing situation of walking dolly vehicle frame 1.
The two ends of described reel 2 are equipped with the rotating shaft that is fixed together with described reel 2, described reel 2 is installed on the described vehicle frame by two bearing seats 7, pairing bearing seat 7 is stretched out in the rotating shaft of the power intake of described reel 2, during use, the output shaft of reductor connects by coupler with the rotating shaft of the power intake of reel 2, when needs dismounting reductor, can easily reel 2 be separated with reductor, and not influence the stressed of reel 2.
The present invention is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within protection scope of the present invention.
