Abstract

The invention discloses an engineering surveying pay-off device, and belongs to the technical field of engineering surveying. The engineering surveying pay-off device comprises wire guiding discs, a rotating shaft A and a fixing cover, the rotating shaft A is installed between the two wire guiding discs, the fixing cover is fixed to the outer sides of the wire guiding discs, a rotating shaft B is arranged in the middle of the rotating shaft A, two limiting rods parallel to the rotating shaft A are arranged between the two wire guiding discs, one limiting rod is provided with a wire guiding mechanism, a manual adjusting mechanism is arranged in the fixing cover located on the left side, and a driving mechanism is arranged in the fixing cover located on the right side. The manual adjusting mechanism and the driving mechanism are arranged, manual or automatic operation can be achieved, meanwhile, the structure is compact, the manual adjusting mechanism and the driving mechanism are correlated and do not affect each other, and the arranged wire guiding mechanism is connected to the interior of the driving mechanism and is manually and automatically controlled, so that the problems that in the pay-off process non-uniform winding, untidy arrangement and line pressing problem of reciprocating motion can be solved.

Description

technical field [0001] The invention relates to the technical field of engineering surveying, in particular to an engineering surveying and setting-out device. Background technique [0002] Building construction setting out is one of the necessary skills for construction managers. The beginning of each construction project is construction positioning and setting out, which is related to the success or failure of the entire project. The construction setting out is through the prior inspection of the construction project positioning and setting out. Ensure that the construction project is carried out safely and smoothly in accordance with the requirements of planning approval, while taking into account the improvement of municipal facilities and environmental quality, so as to avoid infringement on the interests of adjacent property owners. [0003] There are many tools that need to be carried and used in the construction measurement process, including spirit levels, range fin...
