Embodiment Construction

[0029] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.

[0030] A trolley for measuring the flatness and span of the track of the aerial crane, including a traveling device 3 that can be sleeved on the track of the aerial crane. The inner side of the traveling device 3 is provided with a pulley block 4 that interacts with the track surface, and the top surface of the traveling device 3 passes through the The connecting mechanism is provided with a 360° measuring prism 1 . It can be understood that the pulley block 4 is arranged on the inner side of the running device 3 to interact with the track to reduce friction and improve the smoothness of the running device 3 moving along the track. With the 360° prism setting, the position coordinates of the prism can be re...

Abstract

The invention relates to the technical field of nuclear power industry engineering construction auxiliary monitoring devices, and discloses a trolley for measuring flatness and span of a crane rail. The trolley comprises a walking device capable of being sleeved on the crane rail, and a pulley block interacting with a rail surface is arranged on the inner side of the walking device. A 360-degree measuring prism is arranged on the top face of the walking device through a connecting mechanism, the walking device is connected with a crane and is driven by the crane to walk along the rail, a prismdoes not need to be arranged on the rail by monitoring personnel, the working difficulty is reduced, the working efficiency is improved, the safety of the monitoring personnel is guaranteed, and theoverall structure is simple. The track flatness and span can be monitored without manual assistance, the efficiency is improved, the cost is reduced, and the trolley has great popularization value andwide application prospect.

Description

technical field [0001] The invention relates to the technical field of auxiliary monitoring devices for nuclear power industrial engineering construction, in particular to a trolley used for measuring the flatness and span of an aerial crane track. Background technique [0002] In the construction of the third-generation nuclear power reactor type "Hualong One", due to the large amount of work, it is necessary to build a large number of temporary processing plants. For crane equipment, the track of the aerial crane is arranged on the steel structure corbel, so the height is relatively large, while the temporary factory building is mostly built in the backfill area, and the settlement is relatively large; during the use of the aerial crane, due to the uneven settlement deformation of the factory building, the track The deformation during use and the creep of the track itself will cause the span and flatness of the track to exceed the limit of use; there is no corresponding pl...
