Problems solved by technology

[0003] At present, the hanging baskets in the existing bridge deck cranes erecting viaducts are designed to be anchored and fixed, so they do not have the free adjustment in the longitudinal direction, and the requirements for the dimensional accuracy of the bridge pre-embedded and lifting holes are very high, which can easily lead to misalignment. In addition, the truss used in the bridge deck crane is usually integrally formed, the structure is complex, the processing cost is high, and it cannot meet the requirements of modern bridge construction technology

specific Embodiment approach

[0029] Further, see figure 1 and image 3 , as a specific embodiment of the bridge deck crane provided by the present invention, the lifting mechanism 3 includes a hanging basket 31 and a lifting assembly 32. The lifting assembly 32 is arranged on the load-bearing truss 1 and can drive the hanging basket 31 to lift. The hanging basket 31 is provided with a first sensing device 33, and the support column 21 is provided with a second sensing device 34. The first sensing device 33 can cooperate with the second sensing device 34 to monitor whether the hanging basket 31 has reached a preset height. . In this way, when the hanging basket 31 rises under the driving of the lifting assembly 32, and when the hanging basket 31 rises to a preset height, the second sensing device 34 and the first sensing device 33 sense each other to send a signal, and the lifting assembly 32 stops driving. The hanging basket 31 rises, which improves the splicing efficiency and shortens the construction ...

Abstract

The invention relates to the technical field of bridge construction, and specifically discloses a bridge deck crane, including a first truss, a second truss spliced ​​with the first truss to form a load-bearing truss, and a first adjustment mechanism arranged at the bottom of the load-bearing truss , the load-bearing truss is provided with a lifting mechanism and a second adjustment mechanism, the first adjustment mechanism includes a support column, and an adjustment handle, the second adjustment mechanism includes a pair of guide rails inclined at the bottom end of the load-bearing truss, and a pair of guide rails arranged on the guide rails the locking mechanism. In this way, the load-bearing truss is formed by splicing the first truss and the second truss, which avoids an increase in the cost of the truss due to integral molding; by providing a lifting mechanism and a second adjustment mechanism on the load-bearing truss, the lifting mechanism can lift the bridge. On the other hand, the second adjusting mechanism can adjust the longitudinal displacement of the lifting mechanism, and when the lifting mechanism moves to a proper position, it can be locked by the locking mechanism in the second adjusting mechanism.

Description

technical field [0001] The invention relates to the field of bridge construction, and specifically discloses a bridge deck crane. Background technique [0002] With the advancement of bridge construction technology, the bridge construction technology has changed from traditional cast-in-place construction to modern prefabricated assembly construction. Modern prefabricated assembly construction is easy to realize mechanized construction, the upper and lower structures can work in parallel, shorten the on-site construction period, and meet the requirements of safe, efficient and economical modern infrastructure construction. It is against this background that the bridge deck crane came into being as a special erection equipment. [0003] At present, the hanging baskets in the existing bridge deck cranes erecting viaducts are designed to be anchored and fixed, so they do not have the free adjustment in the longitudinal direction, and the requirements for the dimensional accura...
