Description

Big machine lofting instrument Technical Field The utility model belongs to the technical field of construction measuring tools for a large machine, and particularly relates to a large machine lofting tool. Background A certain line workshop has a line mainframe construction task of nearly 100 kilometers every year, the workshop is the most busy time during the construction period of the mainframe, and continuous construction operation and night shifts are quite arduous for people who do the mainframe, especially people who loft the mainframe before and after. With the situation that the work load of the large machine is unchanged due to the fact that the number of workers in a workshop is reduced, the improvement of the construction efficiency of the large machine and the saving of manpower become particularly important, but under the construction conditions of the prior art and tools, the efficiency is intended to be improved, the manpower is saved, and accordingly the large problem is also caused. The existing large machine lofting method is that an L-shaped ruler is used for measuring the height difference of a steel rail surface before and after a large machine at a lofting point, a 5 meter ruler is used for measuring the lateral movement quantity of the steel rail, so that whether the working effect of the large machine reaches the standard or not is calculated, but the L-shaped ruler is longer and larger, the erection is inconvenient, and the use in an electrified section is unsafe. And whether the L-shaped ruler or the 5 meter ruler can be completed by two operators, and 4 operators are needed for one-machine construction before and after the operation, so that pressure is caused to force distribution. Therefore, the scheme is to improve the existing lofting tool. Disclosure of utility model Aiming at the problems of low working efficiency, insufficient manpower and the like of the existing large-scale construction lofting operation, the utility model designs the lofting tool special for the large-scale construction, greatly improves the working efficiency of lofting, saves manpower, and is simple to operate and accurate in lofting measurement. In order to achieve the above purpose, the present utility model adopts the following technical scheme: a master loft tool, comprising: a bracket which can be arranged on the rail head of the steel rail; the mounting seat is hinged with the bracket; The adjusting component is connected to the bracket and used for leveling the mounting seat; And the electronic distance meter is connected with the mounting seat. As a further scheme of the utility model, the upper surface of the mounting seat is a horizontal plane, the electronic range finder is fixedly connected to the upper surface of the mounting seat, and a level meter is arranged on the upper surface of the mounting seat. As a further scheme of the utility model, the adjusting assembly comprises a nut seat and an adjusting bolt, wherein the nut seat is fixedly connected to the bracket, and the output end of the adjusting bolt is abutted against the lower surface of the mounting seat.
