Embodiment Construction

[0036] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] Please combine Figure 1 to Figure 4 As shown, a lifting and shifting device for a large bridge crane provided by the present invention includes a lifting device 100 and a rail 2 arranged on a dock surface 1 .

[0038] The bottom of the elevating device 100 has two pressure beams 3 arranged in parallel, and the two pressure beams 3 are connected by a lateral stabilizer 11. The elevating device 100 needs to be strengthened, and the elevating device 100 needs to be strengthened by using a lateral stabilizer 11. Stabilize and strengthen the pressure beam 3 .

[0039] Both ends of the two pressure beams 3 are connected with long pressure beams 4 to increase the length of the pressure beams 3 .

[0040] The prosthetic leg 5 is connected on the long pressure beam 4 .

[0041] A jacking trolley 6 is provided on the track 2,...

Abstract

The invention discloses a lifting shifting device for a large-scale bridge crane and a shifting method. The lifting shifting device comprises a lifting device and a track arranged on the wharf surface; two parallelly arranged pressing beams are arranged at the bottom of the lifting device, the two pressing beams are connected through a transverse stable support, and eiking pressing beams are connected to the two end parts of the two pressing beams; fake legs are connected to the eiking pressing beams; jacking trolleys are arranged on the track, and the number of the jacking trolleys is consistent with the number of the fake legs; and trolley supporting seats are arranged at the top ends of the jacking trolleys, and the trolley supporting seats are connected with the bottom ends of the fakelegs. According to the lifting shifting device for the large-scale bridge crane and the shifting method, the integral shifting and integrated installation of the lifting device are realized, and thusthe batch and pipelined heightening transformation of the bridge crane is realized.

Description

technical field [0001] The invention relates to the heightening technology of large-scale bridge cranes, and more specifically, relates to a lifting and shifting device and a displacement method for large-scale bridge cranes. Background technique [0002] According to the operating characteristics of the existing bridge crane elevating device, every time a bridge crane is raised, it is necessary to dismantle and install the elevating device on the bridge crane again, and it takes about two weeks to dismantle and reinstall the elevating device time. For the situation where multiple bridge cranes need to be rebuilt in batches, dismantling and assembling operations will consume a lot of time, especially for those wharves that are relatively busy and have expensive labor costs, such time consumption is almost unacceptable. The overall movement of the device in and out saves the process of dismantling and assembling the lifting device, which will save a lot of time and cost. C...
