Abstract
The utility model discloses a turn to equipment on circular orbit for hoisting equipment, including basic ring rail and turn to the device, basic ring rail's central authorities set up the annular groove track, turn to the device and include two sets of bendings to car and load-bearing platform, set up two sets of bendings to the car on the basic ring rail, two sets of bendings set up the fortune runner to the car bottom, the fortune runner moves in the annular groove track, and two sets of bendings erect load-bearing platform to between the car, load-bearing platform comprises a plurality of strengthening ribs of welded between two parallel arrangement's steelframe and two parallel arrangement's the steelframe, and two sets of bendings are unanimous to the traffic direction and the speed of car. The two groups of turning cars are synchronously controlled. In order to achieve the lifting effect, a lifting device must be installed on the bearing platform. The utility model discloses utilize basic ring rail and the cooperation that turns to the device, realize hoisting apparatus freely and turn to on basic ring rail, can realize 360 turning to, furthest performance ring rail's effect.
Description
Technical Field
The utility model belongs to the technical field of large-scale hoisting equipment, more specifically say, relate to a steering gear on circular orbit for hoisting equipment.
Background
The circular track crane is a large-scale arm type hoisting device which moves by means of a fixed circular track, has the advantages of simple structure, small ground pressure, huge hoisting capacity and the like, and has irreplaceable important position in the hoisting field.
Modular design and construction in the engineering field have become a new trend, and both in the marine engineering field and the petrochemical field, or in other fields such as the bridge construction field, etc., gradually tend to be modular design and installation modes.
And in the aspect of petrochemical hoisting, a large module is adopted for installation, so that the construction speed is increased, and the investment benefit is maximized. This requires that the lifting apparatus must be ultra-large. Although our country has produced the largest crawler crane in the world XGC 8800. However, the maximum lifting moment is only 88000t.m, and the crawler crane cannot be developed any more in terms of lifting moment due to the structural limitation of the crawler crane (mainly the limitation of a slewing gear). The hoisting engineering requiring the ultra-large hoisting moment cannot be met, so that the development of the ultra-large circular rail crane in China is imperative.
After the circular rail crane is subjected to load sharing through the bogie and the circular rail, the requirement on the ground is low.
The most important function of the circular rail crane is to lift heavy objects and have good steering effect, and the steering effect should have 360-degree steering and positioning.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: the utility model aims at prior art not enough and defect, provide a turning to equipment on circular orbit for hoisting equipment, utilize basic orbits and the cooperation that turns to the device, realize hoisting apparatus freely and turn to on basic orbits, can realize 360 turning to, arrange with the carrier loader, furthest performance ring rail's effect.
The technical scheme is as follows: in order to realize the above purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a turn to equipment on circular orbit for hoisting equipment, includes basic ring rail and turns to the device, basic ring rail's central authorities set up the annular groove track, turn to the device and include two sets of curved cars and load-bearing platform, set up two sets of curved cars on the basic ring rail, two sets of curved car bottoms set up the fortune runner, the fortune runner moves in the annular groove track, and two sets of curved cars erect load-bearing platform between, load-bearing platform comprises a plurality of strengthening ribs of welded between two parallel arrangement's steelframe and two parallel arrangement's steelframes, the traffic direction and the speed of two sets of curved cars are unanimous.
Furthermore, the utility model discloses a further technical scheme do: the two groups of the turning vehicles are arranged in a synchronous control mode.
Furthermore, in order to achieve the lifting effect, a lifting device must be installed on the bearing platform.
Has the advantages that: compared with the prior art, the utility model, its beneficial effect is:
(1) the utility model discloses utilize basic ring rail and the cooperation that turns to the device, realize hoisting apparatus freely and turn to on basic ring rail, can realize 360 turning to, arrange with the carrier loader, furthest performance ring rail's effect.
(2) The utility model discloses a ground connection specific pressure is little, hoisting capacity is strong, with carrier loader collocation, has played the good effect that hoisting apparatus turned to on the circular orbit.

Fig. 2 is the utility model relates to a turning to the structural schematic diagram of equipment on circular orbit for hoisting equipment.
Detailed Description
The present invention will be further described with reference to the following detailed description.
As shown in fig. 1 and 2, an upper turning device of an endless track for a hoisting device includes a base endless track 1 and a turning device. The central authorities of basis ring rail 1 set up the annular groove track, turn to the device and include two sets of curved car 2 and load-bearing platform 3, set up two sets of curved car 2 on the basis ring rail 1, two sets of curved car 2 bottoms set up the fortune runner, the fortune runner moves in the annular groove track, erects load-bearing platform 3 between two sets of curved car 2, load-bearing platform 3 comprises a plurality of strengthening ribs 4 of welded between two parallel arrangement's steelframe and two parallel arrangement's steelframe, two sets of curved traffic directions and the speed of car are unanimous.
The two groups of the turning vehicles 2 are arranged in a synchronous control mode.
And a hoisting device is arranged on the bearing platform 3.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
