Abstract
The utility model discloses a kind of overhanging driver's cab gantry crane, comprise girder, girder is connected with ground rail with flexible leg by rigid leg, girder is equipped with dolly, the side of upper dolly is fixedly connected with the connect box of oriented side-lower inclination, the other end of connect box is provided with driver's cab, is provided with ladder in connect box, and ladder extends to above driver's cab.Structure is simple, distance lifting object apart from short, with upper dolly transverse shifting, namely can clearly can observe lift heavy position and state down, trolley travelling situation can be observed upward.
Description
Technical field
The utility model relates to elevator machinery technical field, is specifically related to a kind of overhanging driver's cab gantry crane.
Background technology
Large-sized gantry formula hoisting crane generally has upper and lower two trolley bodies, when needing the steel construction pieces such as lifting boat segmental, upper and lower trolley body runs to segmentation overhead, hook segmentation, upper and lower dolly horizontal sliding on girder, hoisting crane is walked along ground rail, until segmentation is transported to target place.
Gantry crane driver's cab of the prior art is installed on rigid leg, even if operating personal has barrier obstruction, also can only be fixed in this position, by means of operating experience or felt to crane hoisting and traveling gear control.Along with the develop rapidly of China's shipbuilding cause, the width in building berth and depressed place is increasing, and the gantry crane span also corresponding increase of configuration, the orbital distance of gantry crane is increasing, has even exceeded 200mm.Remote-control rack seriously tests the vision condition of operating personal.Especially at night time operation equipment, light is failed to understand in addition, and occur that major accident situation happens occasionally, often fatal crass, suffers heavy losses.And whether inspect upper and lower dolly and break down and need service personnel to climb up girder, maintenance workload is large.Therefore, improvement gantry crane driver's cab of the prior art being carried out to position setting is necessary.
Utility model content
The purpose of this utility model is the defect overcoming prior art, provide that a kind of structure is simple, distance lifting object apart from short, can with the overhanging driver's cab gantry crane of upper dolly transverse shifting.
For achieving the above object, the technical solution of the utility model is a kind of overhanging driver's cab gantry crane, it is characterized in that, comprise girder, described girder is connected with ground rail with flexible leg by rigid leg, and described girder is equipped with dolly, the side of described upper dolly is fixedly connected with the connect box of oriented side-lower inclination, the other end of described connect box is provided with driver's cab, is provided with ladder in described connect box, and described ladder extends to above described driver's cab.
The transverse shifting of upper dolly will inevitably cause the vibrations of driver's cab, and it is poor by means of only casing connection safety between upper dolly and driver's cab, in order to the vibrations reducing driver's cab are gone forward side by side the safety of one-step optimization driver's cab, preferred technical scheme is, is also connected with at least two steel ropes between described upper dolly and driver's cab.Steel rope can be used as safety rope, for the operating personal in driver's cab heavily insures for providing one more.
When the height of driver's cab is lower, the lifting object lateral rotation on crane hook, can constitute a threat to the safety of driver's cab, and preferred technical scheme is, the bottom of described driver's cab is a little less than the bottom surface of described girder.
In order to avoid upper dolly is unbalance because of the weight of side connect box and driver's cab, and then occur the phenomenon of gnawing rail, preferred technical scheme is, the opposite side of described upper dolly is provided with the clump weight for keeping upper dolly both sides stress balance.
In order to ensure the safety of operating personal when going up or down stairway further, preferred technical scheme is, is also provided with handrail above described ladder.
Advantage of the present utility model and beneficial effect are:
The utility model is by being arranged on position on the lower side, girder side by driver's cab, operating personal is positioned at above lift heavy all the time, namely lift heavy position and state can clearly be observed down, eliminate remote on the visual demand of operating personal and the impact of obstacle, avoid operating personal with sensation and experience operational outfit;
Be arranged on by driver's cab near base plate vicinity outside girder, can observe trolley travelling situation upward, operating personal also can realize inspecting upper and lower dolly by the ladder in upper and lower connect box, facilitates the maintenance of crane girder Shang Ge mechanism.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1 to Figure 3, the overhanging driver's cab gantry crane of embodiment, comprise girder 1, girder 1 is connected with ground rail with flexible leg (not shown) by rigid leg 2, girder 1 is equipped with dolly 3, the side of upper dolly 3 is fixedly connected with the connect box 4 of oriented side-lower inclination, and the other end of connect box 4 is provided with driver's cab 5, be provided with ladder 6 in connect box 4, ladder 6 extends to above driver's cab 5.
In the present embodiment, at least two steel ropes 7 are also connected with between upper dolly 3 and driver's cab 5; The bottom of driver's cab 5 is a little less than the bottom surface of girder 1; The opposite side of upper dolly 3 is provided with the clump weight 8 for keeping upper dolly 3 both sides stress balance; Handrail 9 is also provided with above ladder 6.
Install tightening device additional to steel rope, the effect that steel rope can be made to reduce driver's cab vibrations is optimized further.
Compared with being arranged on rigid leg with by driver's cab, the crane operator in the present embodiment need to climb up girder again under in driver's cab, but the operating personal in driver's cab can be more precisely reliable for the control of lift heavy.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
