Abstract
The utility model discloses a connecting device for connecting a top rotating part and a rotary supporting device of a crane. The connecting device comprises an upper flange plate and a lower flange plate, between which a web and a plurality of rib plates are arranged. The upper flange plate and the lower flange plate are respectively connected with the top rotating part and the rotary supporting device of the crane; the outer part of the upper flange plate is square and the inner part is round; and the lower flange plate is round. The upper flange plate is changed from round to be square and the size of the rib plates at the corresponding part is increased, thus enlarging the contact area of the upper flange plate and the top rotating part, improving the stress dispersion of the connecting device and the top rotating part, and greatly reducing the stress concentration at the contact place. Therefore, the whole structure is in a good relatively balanced stress strain status. The added rib plates are evenly distributed around a bolt hole on the lower flange plate, which, for one thing, has the functions of supporting the upper and lower flanges and strengthening the rigidity of the upper and lower flanges, and for the other thing, improves the stress strain status of the whole structure to enable the force to be well dispersed.
Description
Technical field
The utility model relates to a kind of crane equipment, the connecting device between specifically a kind of hoisting crane top rotating part and the rotary supporting device.
Background technology
Present seat type or high-level slewing tower crane rotary supporting device mainly contain two kinds of versions: central pest slewing ring device and rotating disc type rotary supporting device, rotating disc type rotary supporting device mainly contain roller jacket type (being replaced by rolling bearing type gradually) and rolling bearing type rotary supporting device.Rolling bearing type rotary supporting device scantling of structure compactness, perfect performance can bear vertical power, horizontal force and capsizing moment simultaneously, is most widely used a kind of rotary supporting device.For guaranteeing the bearing arrangement normal operation, fixing frame with the connection bearing seat ring is required to have enough rigidity.The mounting means of this mechanism is that hoisting crane top rotating part is fixed on the revolution seat ring of rolling bearing type rotary supporting device, the revolution seat ring of rolling bearing type rotary supporting device then with the concrete mutuallies such as end face of bottom underframe, gate seat bottom surface, inferior holder structure.The last lower connecting device of traditional rolling bearing type rotary supporting device all adopts all similar to the rotary supporting device cross section circular race of joint face up and down, and this version scantling of structure compactness make simply, but structure stress is unbalanced.Especially the junction stress concentration of the revolution seat ring of top rotating part and rolling bearing type rotary supporting device is especially outstanding.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of structure itself and top attaching parts thereof all good, the compact conformation of stress equalization, easy installation and removal, the succinct hoisting crane top rotating part attractive in appearance of profile and the connecting device between the rotary supporting device are provided.
For achieving the above object, the utility model adopts following technical proposals: the connecting device between a kind of hoisting crane top rotating part and the rotary supporting device, it comprises top flange plate and bottom wing listrium, be provided with web and some gussets between the upper and lower flange plate, upper and lower flange plate is connected with rotary supporting device with hoisting crane top rotating part respectively, and upper and lower flange plate is respectively square-outside and round-inside shape and annular arrangement.
Described web is cylindric steel plate.
Described top flange plate and hoisting crane top rotating part are welded as a whole.
Described bottom wing listrium links together by the revolution seat ring of high strength bolt and rotary supporting device.
Described gusset and the even cross-distribution of bottom wing listrium upper bolt hole, the upper and lower side of gusset is connected with upper and lower flange plate respectively.
Top flange plate of the present utility model has been made square on original circular basis, the appropriate section gusset also increases, enlarged the area of contact of top flange plate and top rotating part, improved the stress spread condition of the utility model and top rotating part, reduced the stress concentration of contact position greatly, made the total stressing conditions be in the good order and condition of relative equilibrium.Added some gussets are distributed on around the bolt hole on the bottom wing listrium, play on the one hand to support and go up the lower flange, increase the effect of its rigidity, also improve the stressing conditions of structure on the other hand, exert all one's strength and are well spread.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is that the utility model is installed and used constitution diagram.
1. top flange plates wherein, 2. web, 3. gusset, 4. bolt hole, 5. bottom wing listrium, 6. hoisting crane top rotating part, 7. slewing supporting device, 8. revolution seat ring, 9. high strength bolt.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1-Fig. 3, the utility model is made of for web 2 cylindraceous, circular bottom wing listrium 5 and some gussets 3 top flange plate 1, the volume of square-outside and round-inside shape.The utility model top is welded as a whole by top flange plate 1 and hoisting crane top rotating part 6, and the bottom is linked together by the revolution seat ring 8 of high strength bolt 9 with rolling bearing type rotary supporting device 7 by bottom wing listrium 5.Because it is square that top flange plate 1 of the present utility model has been made on original circular basis, appropriate section gusset 3 also increases, enlarged the area of contact of top flange plate 1 of the present utility model and hoisting crane top rotating part 6, improved the stress spread condition of the utility model and hoisting crane top rotating part 6, reduced the stress concentration of contact position greatly, made the total stressing conditions be in the good order and condition of relative equilibrium.The upper and lower flange plate 1,5 of support is played in distributions of evenly reporting to the leadship after accomplishing a task of added some gussets 3 and the bolt hole 4 of bottom wing listrium 5 on the one hand, increases the effect of its rigidity, also improves the stressing conditions of structure on the other hand, exerts all one's strength and is well spread.
