Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] see figure 1 , the bridge crane trolley line installation accuracy measuring instrument provided by the embodiment of the present invention includes a side bar 7, a level scale bar 1, a sliding scale bar 2, a line pendant 5, a level adjustment bar 10 and a level 9, and the level bar 1 is vertical It is installed on the side bar 7 at 200 mm from the lower end, forming an unbalanced "T" shape that falls down. Horizontal adjustment rod 10 is vertically installed on the side rod side of horizontal scale rod 1, and is arranged in parallel with side rod 1, and can change the length by its own screw function, thereby playi...

Abstract

The invention relates to the field of the auxiliary tool of trolley conductor installation and construction of the bridge crane, particularly to a measurement appliance for installation precision of a trolley conductor of a bridge crane. The measurement appliance comprises a side lever, a horizontal scale rod, a sliding scale marker, a line drop body, and a level gauge. The lower end of the side lever is fixed on a crane beam vertically; the horizontal scale rod is installed on the side lever vertically and the horizontal scale rod and the side lever for an inverted T shape; the sliding scale marker sleeves and slides on the horizontal scale rod freely; the line drop body includes a vertical dropping unit suspended to the sliding scale marker by connection of a nylon cord; and the level gauge is used for measuring whether the horizontal scale rod is in a horizontal mode. Therefore, an objective of measurement of key positioning dimensions including a horizontal spacing and a vertical spacing of installation of a trolley conductor can be achieved.

Description

technical field [0001] The invention relates to the field of construction auxiliary tools for trolley line installation of bridge cranes, in particular to an installation accuracy measuring instrument for trolley lines of bridge cranes. Background technique [0002] Overhead cranes are widely used, and the installation of the trolley line of the bridge crane needs to grasp two key installation dimensions, namely: the horizontal distance between the center line of the crane track and the center line of the trolley line, and the distance between the upper surface of the crane track and the trolley line. The vertical spacing of the surface on the line. However, since the installation position of the trolley line of the bridge crane is outside the crane girder, during construction, the slide line bracket must be installed first, and then the insulating porcelain bottle and the trolley line should be installed on the bracket. During construction or positioning measurement, it is...
