The track type container gauntry crane comprises cross sill and wheel case, the wheel of wheel case supports described track type container gauntry crane and advances on planned orbit, the advantage of current track formula container gantry crane is that its span can reach 40 meters (12 row freight containers) or more, as long as the stockyard load-carrying capacity is enough, the heap height can be above 7 to 8 layers, and the track type container gauntry crane also can have overhanging, so the track type container gauntry crane has higher utilization of area rate.The track type container gauntry crane can pass through the direct electricity consumption of electrical network in addition, so its energy consumption is very low.

It is very inconvenient that but the shortcoming of present track type container gauntry crane is the transition problem, because the track type container gauntry crane can only be advanced on fixing track and its wheel case can not turn to, self can not realize transition so present track type container gauntry crane only relies on, so just suppress of the application of track type container gauntry crane in various occasions.

So pressing for provides a kind of later-model track type container gauntry crane, himself can realize turning to, the realization transition of energy quickness and high efficiency, thus better bring into play the value of service of track type container gauntry crane in various occasions.

The utility model content

High and the inefficient defective of transition difficulty, cost that can not turning to property causes that exists at present track type container gauntry crane, the purpose of this utility model provides a kind of from steering-type track type container gauntry crane, so just improved the alerting ability that equipment uses, improved the efficient of transition and reduced cost.

For achieving the above object, it is a kind of from steering-type track type container gauntry crane that the utility model provides, comprise cross sill and wheel case, described cross sill is connected with described wheel case by rotating shaft, described cross sill and wheel case are that the bearing pin of vertical direction is fixed, described cross sill has push rod, and described push rod is connected with the wheel case to drive it in the horizontal direction around described rotating shaft rotation.

Described bearing pin top is connected with hydraulic actuating cylinder one end, and the described hydraulic actuating cylinder other end is connected with cross sill.

The upper head plate of the bottom plate of described cross sill and wheel case has pin shaft hole and mates mutually, described bearing pin and described pin shaft hole coupling.

Described push rod is a motor-driven, and push rod one end and described wheel case flexibly connect, and the push rod other end and described cross sill flexibly connect.

Described radius-rod drive wheel case is 90 degree rotary states in the horizontal direction.

Adopt described in the utility model from steering-type track type container gauntry crane, because the cross sill from steering-type track type container gauntry crane is connected with the wheel case by rotating shaft, and have bearing pin and a push rod, fix described cross sill and wheel case with bearing pin during work, unclamp bearing pin in the time of need turning to, the described wheel case of radius-rod drive turns to around the shaft simultaneously, turn to and insert bearing pin again after finishing, when from steering-type track type container gauntry crane after turn to track to arrive the desired location, make from the steering-type track type container gauntry crane state of resuming work.More than find out, adopt the described defective that can solve existing track type container gantry crane transferring difficulty from steering-type track type container gauntry crane preferably, and the utility model can also carry out automatic guidance in the transition process, can realize fast like this, transition efficiently.

The specific embodiment

Further specify the technical solution of the utility model below in conjunction with drawings and Examples.

With reference to figure 1 and Fig. 2, the utility model provides a kind of from steering-type track type container gauntry crane, with reference to figure 3, from steering-type track type container gauntry crane 100, comprise cross sill 10 and wheel case 20, described cross sill 10 is connected (with reference to figure 5) by rotating shaft 40 with described wheel case 20, below the wheel case 20 wheel is installed, described cross sill 10 and wheel case 20 are that the bearing pin 30 of vertical direction is fixing, described cross sill 10 has push rod 50, and described push rod 50 is connected with wheel case 20 to drive its 40 rotations around the shaft in the horizontal direction.

With reference to figure 5, rotating shaft 40 the first half and cross sill 10 are fixing, rotating shaft 40 has the shaft shoulder 41, between two parts, countershaft 40 has played positioning action to the shaft shoulder 41 about connecting portion, and connecting portion has a packing ring between two parts up and down, axle sleeve is arranged outside the rotating shaft 40, by rotating shaft 40, rotating shaft 40 lower parts are connected with wheel case 20, wheel case 20 40 rotations around the shaft.

With reference to figure 4, the top of described bearing pin 30 is connected with hydraulic actuating cylinder 31 1 ends, and described hydraulic actuating cylinder 31 other ends are connected with cross sill 10; With reference to figure 6, the bottom plate 11 of described cross sill 10 and the upper head plate 21 of wheel case 20 have pin shaft hole and mate mutually, described bearing pin 30 and described pin shaft hole coupling.
