Abstract

The invention discloses a box beam moving trolley which solves the serious consequences possibly caused by the inconformity of the running speeds of a rigid car and a soft car at the two sides of a guide rail existing in the prior art. The invention comprises large support saddles, an oil jack, a bearing beam and a driving shaft component. The oil jack is arranged on the bearing beam and the front part and the rear part of the oil jack are respectively provided with a large support saddle; the large support saddles are arranged on the bearing beam; the box beam moving trolley also comprises three sets of protection devices which are respectively a travel switch and a stop crossbeam arranged at the two sides of the large support saddles and an encoder arranged at one side of the driving shaft component. Compared with the prior art, the box beam moving trolley of the invention has the advantages of adopting redundant protection, ensuring the conformity of the running speeds of the rigid car and the soft car and having simple and easy implementation.

Description

technical field [0001] The invention relates to construction engineering equipment, in particular to a box girder mobile trolley. Background technique [0002] With the progress of society and the accelerated development of economic construction, the total mileage of national railway construction is expected to reach 100,000 kilometers in 2020; for the formwork of the subgrade in railway construction, it is moved to the designated position after the beam making yard is finished. , Box girder mobile trolley is widely used because of its cheap price and reliable performance. [0003] The box girder mobile trolley is composed of a rigid car and a soft car. The oil roofs on the rigid car and the soft car respectively withstand the two ends of the formwork. The oil roof is directly fixed on the supporting beam, and the length of each formwork can be It reaches 32 meters and weighs 2,400 tons. During the process of moving the formwork with the box girder mobile trolley, there may...
