A kind of gauntry crane
Technical field
The utility model belongs to the elevator machinery technical field, is specifically related to a kind of gauntry crane of large span big elevating capacity.
Background technology
At present, two supporting legs that the large span gauntry crane that shipyard is used generally comprises girder and is connected with girder, the lower end of two supporting legs is fixed with corresponding grade beam, grade beam is provided with the mobile road wheel that is assemblied on large Car Track, the mobile dolly that is equipped with on girder, be installed with lifting mechanism on dolly, the structure that hoists comprises hoisting drum, drive actuating device, the fixed pulley group that is installed in dolly that hoisting drum rotates, be used for the running block and the steel rope that are connected mutually with suspender, steel rope connects suspender by running block, and this suspender is implemented the handling of goods.When needs handling article, dolly moves on girder, and the grade beam of hoisting crane drives supporting leg and girder slides along track, after reaching the desired location, implements the article handling.But the lifting mechanism of above-mentioned gauntry crane is arranged on dolly, so just makes dolly weight larger, the equal more complicated of the structure of dolly and manufacturing process, and the dolly productive costs is higher.In addition, because the span of gauntry crane is larger, this just proposes high requirement to the overall construction intensity of hoisting crane, and the total quality that needs to improve hoisting crane is to satisfy the requirement of crane structure intensity, and this also can increase productive costs.
The utility model content
The purpose of this utility model is to provide a kind of gauntry crane, carries hoisting drum and actuating device and causes the larger technical matters of dolly weight with the dolly that solves gauntry crane of the prior art.
for achieving the above object, the technical scheme of gauntry crane provided by the utility model is: gauntry crane, comprise girder and two supporting legs that are connected with girder, two supporting leg lower ends are fixed with corresponding grade beam, the mobile dolly that is equipped with on girder, described gauntry crane also comprises lifting mechanism, this lifting mechanism comprises hoisting drum, the actuating device that is in transmission connection with hoisting drum, be installed in the fixed pulley group on dolly and be wrapped in the steel rope between reel and fixed pulley group in unison, described hoisting drum and actuating device are fixedly mounted on supporting leg or the grade beam corresponding with supporting leg.
Also be provided with the reverse wheel for the commutation of steel rope pile warp that is arranged between hoisting drum and fixed pulley group on described girder.
Described girder is provided with the location division, this location division and hoisting drum lay respectively at described fixed pulley group both sides, and an end of described steel rope is installed on hoisting drum, the other end is connected on described location division after pile warp reverse wheel, fixed pulley group and running block after laying out hoisting drum successively.
Described reverse wheel and fixed pulley group and position point are in sustained height.
The beneficial effects of the utility model are: the hoisting drum of gauntry crane provided by the utility model and actuating device are fixedly mounted on supporting leg or the grade beam corresponding with supporting leg, alleviated like this burden of dolly, and simplified vehicle structure, also reduced the weight of dolly, the manufacturing process of dolly also is simplified, improve simultaneously the whole stressing conditions of gauntry crane, so just made the overall construction intensity of hoisting crane to reduce, and then reduced the hoisting crane productive costs.
Description of drawings
Fig. 1 is the lifting mechanism principle of work schematic diagram of a kind of embodiment of gauntry crane provided by the utility model;
Fig. 2 is the structural representation that uses the gauntry crane of lifting mechanism as shown in Figure 1;
Fig. 3 is the left side view of Fig. 2;
Fig. 4 is the right side view of Fig. 2.
The specific embodiment
As shown in Figures 1 to 4, a kind of embodiment of gauntry crane, gauntry crane in this embodiment comprise girder 10 and with two supporting legs 11,12 that are connected in girder 10 two ends, two supporting legs correspondence respectively are supported on two grade beams 13,14, two supporting legs are respectively rigid leg 11 and flexible leg 12, move along the girder length direction on girder 10 and are equipped with dolly 17 and dolly 18.Described gauntry crane also comprises for the lifting mechanism 15 of handling article and lifting mechanism 15, the composition of two cover lifting mechanisms is basic identical, principle of work is also basic identical, include hoisting drum 1, be used for to drive actuating device that hoisting drum rotates, be installed in fixed pulley group 4 on corresponding dolly, be used for hanging running block 5 and the steel rope 2 of suspension hook, the fixed pulley group fixedly is assemblied on corresponding dolly, and is moved along the girder length direction by the dolly drive.gauntry crane in the present embodiment mainly is with the difference of gantry of the prior art lifting: the hoisting drum 1 of lifting mechanism and actuating device are all on fixing assembling and grade beam 13 corresponding to rigid leg 11, be provided with the location division 6 that is connected with steel rope on girder 10, this location division 6 and hoisting drum 1 lay respectively at the both sides of described fixed pulley group 4, also be provided with the reverse wheel 3 for the commutation of steel rope pile warp that is arranged between hoisting drum and fixed pulley group on girder 10, reverse wheel 3 and location division 6 are positioned at the both sides of fixed pulley group, steel rope 2 lays out hoisting drum 1 and at pile warp reverse wheel 3, fixed pulley group 4, be connected in after running block 5 on location division 6, in the present embodiment, because steel rope is laying out at first pile warp fixed pulley group of reverse wheel, and in the end to lay out after the winding system that fixed pulley group and running block form be to lay out through the pulley on the fixed pulley group, the pulley that plays like this wiring effect on the fixed pulley group can be Duoed one than the pulley that plays the wiring effect on running block.Reverse wheel 3 in the present embodiment, fixed pulley group 4 and location division 6 are positioned at sustained height, so that be horizontal at the length of cable that reaches between fixed pulley group and location division between reverse wheel and fixed pulley group.
The hoisting drum of the gauntry crane that provides in above-described embodiment is not arranged on dolly as prior art, and be mounted on the grade beam corresponding with rigid leg, alleviate like this dolly burden, simple and the weight of vehicle structure reduces, the manufacturing process of dolly also is simplified, and can also improve the whole stressing conditions of hoisting crane.Simultaneously, because hoisting drum and actuating device all are placed on apart from the nearer grade beam in ground, be convenient to like this lifting mechanism is carried out repair and maintenance.
In above-described embodiment, reverse wheel and location division are set on girder, the ran between hoisting drum, reverse wheel, fixed pulley group and location division on steel rope all is in the position near supporting leg and girder like this, on the one hand effectively utilized the space, the impact that the steel rope of also avoiding on the other hand pile warp hoisting drum, reverse wheel, fixed pulley group causes the normal handling work of hoisting crane.In other embodiments, also can save reverse wheel, at this moment, the length of cable between reel and fixed pulley group is to tilt to extend, and when crane for hoisting fitfull article, steel rope may affect the normal handling of hoisting crane like this.
In above-described embodiment, hoisting drum and actuating device directly fixedly are assemblied on grade beam, and hoisting drum and drive configuration also can be connected on rigid leg in other embodiments.Certainly, hoisting drum and actuating device can also be by on the bracing frames that is fixedly supported on special setting, and this bracing frame is connected on rigid leg or the grade beam corresponding with rigid leg.
