Description

Technical Field

[0001] The present invention relates to the technical field of bridge deck cranes, and more specifically to an integral bridge deck crane with a double cable plane steel box girder and high load capacity. Background Art

[0002] With the progress of bridge construction technology, the construction technology of bridges has changed from traditional cast-in-place construction to modern prefabricated and assembled construction. Modern prefabricated and assembled construction is easy to realize mechanized construction, and the upper and lower structures can work in parallel, shortening the on-site construction period, meeting the requirements of modern infrastructure construction for safety, efficiency, and economy. For the installation of steel box girders, basically, when the floating transportation conditions are met, the construction method is to ship the beam segments by ship, and the cantilever assembly can be carried out by using a bridge deck crane or the segment installation can be carried out by configuring a large floating crane to set up a support, or the jacking method can also be used for construction.

[0003] When the bridge deck crane suspends the steel box girder for assembly, generally, a single set of suspension mechanism is used to control the lifting and displacement of the steel box girder. However, when the steel box girder is lifted and in a suspended state, its balance is difficult to guarantee. And if an angular inclination occurs, it is difficult to correct and adjust in the air, resulting in a position deviation in the assembly of the steel box girder, increasing the burden of the steel box girder assembly operation. Moreover, the steel box girder is not suspended and stressed stably in the air. For a steel box girder with a large width, there is a risk of uneven stress on the steel box girder and interference and inclination of the ropes, increasing the limitations of the operation of the bridge deck crane.

Cross beam pressing plates 1209 are provided at the output ends of the two hydraulic cylinders 1208, and can descend to contact the surface of the steel box girder through the cross beam pressing plates 1209, greatly ensuring the pressure and comprehensive strength of the top surface of the suspended steel box girder and avoiding the possibility of position inclination and deviation.

[0029] As a preferred solution of this embodiment: Balance blocks are provided at the tops on both sides of the pier top bracket 1, and the auxiliary bracket 4 and the moving track 5 are integrally connected with the main truss 3, increasing the overall structural strength of the device.

[0030] As a preferred solution of this embodiment: The moving track 5 and the traveling crane are in the same vertical plane as the main hoisting mechanism 7, and the two auxiliary ropes 10 and the main rope 8 are in different horizontal planes. The two auxiliary ropes 10 are located at both ends of the main rope 8, enabling the two auxiliary ropes 10 and the main rope 8 to be lifted and lowered synchronously without interference, and at the same time facilitating the individual adjustment of the two auxiliary ropes 10.

[0033] As a preferred solution of this embodiment: lifting lugs adapted to the secondary ear plates 13 are provided at the bottoms of the two groups of secondary ropes 10. Rubber gaskets are provided inside the two groups of secondary ear plates 13, and the rubber gaskets are in contact with the lifting lugs. The stability of the structural connection and the structural strength can be greatly improved through the contact between the rubber gaskets inside the lifting lugs and the secondary ear plates 13.

[0034] As a preferred solution of this embodiment: the bevel gear set 1202 is respectively composed of a first bevel gear and a second bevel gear. A first bevel gear is provided at the output end of the servo motor 1201, and a second bevel gear meshing with the first bevel gear is provided at the middle position outside the bidirectional lead screw 1203, which is convenient for driving the bidirectional lead screw 1203 to rotate and revolve stably by using the structural meshing of the first bevel gear and the second bevel gear.

[0035] As a preferred solution of this embodiment: three guide plates are installed at the bottoms of the mutually remote ends of the two groups of side beam plates 1207, and sliding grooves are provided inside the guide plates, and sliding blocks fixedly connected to the cross beam pressing plates 1209 are provided inside the sliding grooves. The two groups of side beam plates 1207 and the three guide plates at the same end form an L-shaped structure. The stability of the contact and pressing of the cross beam pressing plates 1209 with the steel box girder and the guiding property of the lifting adjustment can be improved by using the structural cooperation of the sliding grooves opened in the guide plates and the sliding blocks.

[0036] As a preferred solution of this embodiment: three pressure sensors are provided inside the two groups of cross beam pressing plates 1209. Anti-slip pads are provided at the bottoms of the two groups of cross beam pressing plates 1209. Positioning members for strengthening the connection with the anti-slip pads are provided on both sides inside the two groups of cross beam pressing plates 1209. The stability of the contact between the anti-slip pads and the surface of the steel box girder can be improved through the strengthening cooperation of the positioning members with the anti-slip pads, and the possibility of the steel box girder slipping off can be avoided.

[0037] Example 1, as Figures 1-6As shown in the figure, the main suspension mechanism is formed by the connection of the main hoisting mechanism 7, the main rope 8 and the main ear plate 14, which is connected to the side of the hanging basket 9. The auxiliary suspension mechanism is formed by the connection of the auxiliary hoisting mechanism 6, the auxiliary rope 10 and the auxiliary ear plate 13, which is connected to both ends of the hanging basket 9. At this time, a connection system can be obtained at the four corners of the top surface of the hanging basket 9. Among them, the two groups of main ear plates 14 and the hanging basket 9 are fixedly connected, and the connection between the auxiliary ear plate 13 and the auxiliary rope 10 can be used as an angle adjustment structure to correct the position when the hanging basket 9 is tilted, increasing the flexibility and safety of the device hoisting operation.

[0038] Example 2, as Figures 1-6 shown in the figure, when the two groups of side beam plates 1207 are unfolded, six guide plates on the bottom surface of the side beam plates 1207 can be driven to unfold synchronously, and the side beam plates 1207 and the guide plates form an L-shaped structure. By using the cooperation of the chute and the slider opened on the guide plate, it is ensured that the cross beam pressing plate 1209 contacts the surface of the steel box girder smoothly and precisely for pressing and stabilizing. At the same time, a pressure sensor is arranged on the bottom surface of the cross beam pressing plate 1209, so as to be in contact with the side of the top of the steel box girder through the pressure sensor, which is convenient for the device to intelligently judge the inclination direction of the steel box girder, so as to quickly correct it through the movement of the auxiliary hoisting mechanism 6 and the traveling crane on the moving track 5.

[0039] Working principle: When the bridge deck crane is working, the traveling crane drives the auxiliary hoisting mechanism 6 to move on the moving track 5 to be in the same vertical plane state as the main hoisting mechanism 7. At this time, the main rope 8 and the auxiliary rope 10 can be lowered through the synchronous start of the auxiliary hoisting mechanism 6 and the main hoisting mechanism 7, driving the whole hanging basket 9 to descend, so as to hoist and connect the steel box girder through the lifting appliance 11. Then, by starting the auxiliary hoisting mechanism 6 and the main hoisting mechanism 7 again, the hanging basket 9 and the hoisted steel box girder can be lifted to carry out the assembly operation of the steel box girder;

[0040] Before the hanging basket 9 and the hoisted steel box girder are lifted, the start of the servo motor 1201 can drive the bidirectional lead screw 1203 to rotate. Then, through the rotation of the bidirectional lead screw 1203, the two groups of internal thread pipes 1204 drive the sleeve 1206 to expand synchronously under the limit cooperation of the guide post 1205. Then, the two groups of internal thread pipes 1204 and the sleeve 1206 can drive the side beam plates 1207 to expand synchronously for spacing adjustment, so that the two groups of cross beam pressing plates 1209 can adapt to steel box girders of different widths. After the structure is adjusted, the start of the hydraulic cylinder 1208 can drive the cross beam pressing plate 1209 to descend and contact the surface of the steel box girder, so that the cross beam pressing plate 1209 is attached to the side of the top surface of the steel box girder, forming pressure to ensure the stable effect of the suspension and hoisting of the steel box girder;

[0041] When the steel box girder is inclined, the traveling crane can be adjusted by moving on the moving track 5, so that the traveling crane drives the auxiliary hoisting mechanism 6 to displace in the opposite direction of the inclination, and then the auxiliary hoisting mechanism 6 drives the auxiliary rope 10 to pull the hanging basket 9 for horizontal correction adjustment. During this period, the main hoisting mechanism 7 and the main rope 8 are used as the main suspension carriers to form a fulcrum, which can stably ensure the stability and accuracy of the horizontal correction of the auxiliary hoisting mechanism 6 and the auxiliary rope 10 pulling the hanging basket 9, and increase the flexibility of the actual operation of the bridge crane.

[0042] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than limiting the protection scope of the present invention. Any simple modification or equivalent replacement of the technical solution of the present invention by those of ordinary skill in the art shall not depart from the essence and scope of the technical solution of the present invention.
