Steel bar spacing marking device

Abstract

The invention provides a steel bar spacing marking device which effectively solves the problems that in the prior art, when the steel bars are laid, the marking precision is poor, the spacing size isinconvenient to control and adjust, and the influence of the ground surface flatness is larger. According to the technical scheme, the device comprises a rectangular shell, a driving shaft penetratesthrough the left side wall of the shell, and a first bevel gear is arranged at the left end of the driving shaft. The upper side of the first bevel gear is meshed with a second bevel gear, the upper end of a center shaft of the first bevel gear is connected with a spline shaft through a universal coupling, and a roller sleeves the spline shaft. A slideway is arranged at one side of the shell, a longitudinal shaft is arranged in the shell and is equipped with a driving wheel, and a first friction disc is arranged at the left side of the driving wheel. A second friction disc is arranged at the right side of the driving wheel, a driven shaft penetrates through the right side plate of the shell, and a cam disc is arranged at the right end of a driven shaft. A connecting rod is connected to thecam disc, a piston cylinder is fixed to the outer side of the right side plate of the shell, the lower end of the connecting rod is hinged to a piston to form a slider-crank mechanism, and a materialstorage box is fixed to the upper end of the shell.

Description

technical field [0001] The invention relates to the technical field of steel bar positioning, in particular to a steel bar spacing marking device. Background technique [0002] At present, in the municipal construction, the distance between road and bridge reinforcing bars is generally all manually marked or set out by workers with a scale in the prior art. In this way, manual marking often leads to large errors, resulting in unbalanced forces in local areas, which not only affects the quality of the project, but also affects the progress of the construction and increases the construction cost. [0003] In the prior art, the patent document with application number 201310084749.4 discloses a steel bar spacing marker for building construction, in order to solve the problems of large randomness and insufficient precision in manual marking. It uses the rotation of the wheel to drive the rotation of the spokes. During the rotation, the spokes first pass through the ink-soaked co...
