Abstract
The utility model relates to an engine room crane of a wind turbine generator system and in particular relates to a mechanical rotary engine room crane of a wind turbine generator system which aims at solving the technical problems that a stationary type engine room crane is too narrow in working range, and that an electric rotary engine room crane is difficult to control, high in production cost and easy to damage. The mechanical rotary engine room crane comprises an electric hoist installed on a cross beam and a pillar connected with the cross beam, and is characterized in that a self-lubricating shaft sleeve is installed in the pillar and is in clearance fit with a rotating shaft of the cross beam, and a locking pin connected with the rotating shaft is arranged at the self-lubricating shaft sleeve on the pillar. The mechanical rotary engine room crane is applied to the wind turbine generator system, and has the advantages of wide working range, simple structure and convenience in operation.
Description
Technical field
The utility model relates to the cabin crane of wind power generating set, particularly a kind of wind power generating set machinery rotation formula cabin crane.
Background technology
When wind power generating set is changed parts in maintenance, need cabin crane that parts are lifted.Mostly adopt the fixed engine room loop wheel machine, because fixed engine room loop wheel machine operating range is too little, the electric rotary of employing cabin crane is arranged also, although its operating range is larger, but the control difficulty, cost is very high, and swiveling gear very easily damages under the rocking of fan vibration and hoist ceiling crane.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of prior art, a kind of wind power generating set machinery rotation formula cabin crane is provided, it is too little to solve fixed engine room loop wheel machine operating range, electric rotary cabin crane control difficulty, high, the damageable technical matters of cost.
The utility model is achieved through the following technical solutions:
A kind of wind power generating set machinery rotation formula cabin crane, comprise: be installed on the hoist ceiling crane on the crossbeam, and the column that is connected with crossbeam, it is characterized in that: in the described column self lubrication bearing is installed, the axis of revolution free-running fit of described self lubrication bearing and described crossbeam is on the described column, be positioned at the self lubrication bearing place and be provided with stop pin with described axis of revolution.
The utility model compared with prior art, because self lubrication bearing is installed in the column, in the self lubrication bearing in the insertion of the axis of revolution on the crossbeam column, the free-running fit realization cabin crane revolution by axis of revolution and self lubrication bearing realizes fixing by screwing of stop pin.Therefore, the utility model not only can be realized revolution, and operating range is larger, and simple in structure, and cost is low, and is easy to operate, easy to control.
The utility model is used for wind power generating set, and it is large to have operating range, simple in structure, easy to operate, advantage.
Description of drawings
Fig. 1 is the structural representation of the fixed engine room loop wheel machine of prior art;
Fig. 2 is the structural representation of the electric rotary cabin crane of prior art;
Fig. 3 is structural representation of the present utility model.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 3, a kind of wind power generating set machinery rotation formula cabin crane, comprise: be installed on the hoist ceiling crane 1 on the crossbeam 5, and the column 2 that is connected with crossbeam 5, in the described column 2 self lubrication bearing 3 is installed, axis of revolution 5.1 free-running fits of described self lubrication bearing 3 and described crossbeam 5 are on the described column 2, be positioned at self lubrication bearing 3 places and be provided with stop pin 4 with described axis of revolution 5.1.
When the parts in the maintenance cabin need to lift by crane, unclamp first stop pin 4, then promote crossbeam 5, the axis of revolution 5.1 of crossbeam 5 installs around column 2 rotations of self lubrication bearing 3, thereby drive hoist ceiling crane 1 to suitable position, tighten again stop pin 4, fixing rear lifting parts.
Claims (1)
