Abstract
The invention discloses a double-track height-variable gantry tower crane. The double-track height-variable gantry tower crane comprises a tracked and height-variable gantry base and a tracked tower crane, wherein the tracked and height-variable gantry base comprises a ground track, fixed legs, a plurality of sections of telescopic legs and a transverse beam track, and is of a double-main-beam symmetric structure; the transverse beam track is a wedge-shaped steel track; the tracked tower crane is connected with the gantry base through the transverse beam track in a double-rim connection manner. According to the double-track height-variable gantry tower crane, lifting, bidirectional movement, rotation and amplitude variation mechanisms can be operated independently and can be used cooperatively to complete needed operation contents. The double-track height-variable gantry tower crane has the combined advantages of a gantry tower crane and a tower crane, so that requirements on cargo hoisting in places with port restrictions and geographic restrictions can be met, and quite part of consumption of operation energy can be reduced.
Description
Technical field:
The present invention relates to tower crane technical field, specifically a kind of double track uprises gate seat tower crane.
Background technology
Rubber-tyred mobile crane, span winch, tower crane, as ripe lifting product, because of its usage condition and operating characteristic separately, are widely applied from different occasions such as lifting operations at engineering construction.Span winch adopts wheel track walking, because having track on its crossbeam, can be in the situation that gantry base be not mobile mobile cargo on demand just, saved comparatively speaking the energy.The goods outside a beam but span winch can not be sling, and its beam is because huge structure can not be placed everywhere, in use often has limitation.In tower crane, cab over type, movable arm type were developed rapidly in recent years, wherein arm tower crane is because jib can change within the specific limits, be applicable to very much the construction of intensive and narrow area, more and more be used widely, but traditional tower crane needs base to move together, and the repeatedly walking of heavy wares needs the support of quite a few energy, in the modern society of resource scarcity, the requirement of saving the energy when reaching application target is quite urgent.
Summary of the invention:
The object of this invention is to provide a kind of double track and uprise gate seat tower crane, can realize hoist, the independently working of way moving, rotation, luffing mechanism, also can combine use, to complete needed job content, can meet the lifting handling at the goods on the ground such as harbour, also can meet the use in conditional place geographically, can reduce the energy resource consumption of quite a few again simultaneously.
The present invention achieves the above object by the following technical programs: a kind of double track uprises gate seat tower crane, includes track and gantry base that can uprise and the tower crane two parts that have track.The described gantry base that has track and can uprise comprises ground rail, Convenient table, several sections of Retractive leg, crossbeam track, is two girder symmetrical structures, and described crossbeam track adopts wedge shape rail.Employing segment type uprises, and by hydraulic telescopic device, is realized and being uprised, and by snap fastening device, realizes the fixing of height.Described have the tower crane of track to comprise reaction plate, rolling disc, operator's compartment, Shears, trunk, swing arm, winch and hoist rope, is connected, for two-wheel edge connects with gantry base by crossbeam track.Described hoist rope is walked around Shears and the trunk weight of slinging.
Outstanding advantages of the present invention is:
By gantry base that has track and can uprise being moved to the job position that needs handling to use, tower crane on crossbeam track is picked up goods within the specific limits, by the swing of swing arm and the rotation of rolling disc, realize luffing, easily, realize simply the object of handling goods, both reached the object of lifting lift cargo, do not need mobile gantry base constantly, thereby in the situation that meeting function needs, saved again the energy yet.Accompanying drawing explanation
Fig. 1 is the structural representation that double track of the present invention uprises gate seat tower crane.
Fig. 2 is that the crossbeam track that double track of the present invention uprises gate seat tower crane is connected enlarged drawing with the wheel that gets on the right track.
Fig. 3 is the crossbeam track birds-eye view that double track of the present invention uprises gate seat tower crane.
Fig. 4 be double track of the present invention uprise gate seat tower crane uprise leg structure figure.
In figure, be labeled as: reaction plate 1, rolling disc 2, winch 3, operator's compartment 4, Shears 5, hydraulic actuating cylinder 6, trunk 7, hoist rope 8, swing arm 9, the wheel 10 that gets on the right track, crossbeam track 11, uprises supporting leg 12, base wheel 13, ground rail 14, wedge shape rail 15, dual wheels wheel rim 16, the wheel face 17 that gets on the right track, Convenient table 18, snap fastening device 19, Retractive leg 20, hydraulic telescopic device 21.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is further described.
As shown in Figure 1, a kind of double track uprises gate seat tower crane, includes track and gantry base that can uprise and the tower crane two parts that have track.The described gantry base that has track and can uprise comprises crossbeam track 11, uprises supporting leg 12, base wheel 13, ground rail 14, is two girder symmetrical structures.Described have the tower crane of track to comprise reaction plate 1, rolling disc 2, winch 3, operator's compartment 4, Shears 5, trunk 7, swing arm 9 and hoist rope 8, and described hoist rope 8 is walked around Shears 5 and trunk 7 weight of slinging.
As shown in Figure 2 and Figure 3, described in have the tower crane of track to be connected by crossbeam track 11 with gantry base, described crossbeam track 11 adopts wedge shape rail 15, is square-section, the wheel 10 that gets on the right track adopts dual wheels wheel rims 16.
As shown in Figure 4, four uprise supporting leg and consist of Convenient table 18, snap fastening device 19, Retractive leg 20, hydraulic telescopic device 21, adopt segment type to uprise, and by hydraulic telescopic device 21, are realized and being uprised, by snap fastening device 19, realize the fixing of height, it is selected that Retractive leg joint number is looked particular case.
Principle of work and process:
Operating personal uprises gantry tower crane to whole double track and controls operator's compartment 4 is interior, base wheel 13 moves to job position roughly on ground rail 14, by the wheel 10 that gets on the right track, travelled to correct position again, flexible drive swing arm 9 swings by hydraulic actuating cylinder 6 realize luffing, by winch 3, pulling hoist rope 8 to realize hoists, it is unstable that this kind of luffing mode avoided that jib gravity motion too much causes, and processing safety is improved.
Rolling disc 2, with respect to the rotation of reaction plate 1 moving heavy object more neatly, has been avoided the frequent movement of heavy base, has saved the energy.
The present invention combines the advantage of the hoisting crane of two types, can realize hoist, the independently working of way moving, rotation, luffing mechanism, also can combine use, complete needed job content.Can meet the lifting handling at the goods at harbour, also can meet the use in conditional place geographically, can reduce again the operation energy resource consumption of quite a few simultaneously.
