Dotting device for a roads and a bridge based on municipal building construction

Abstract

The invention discloses a dotting device for a road and a bridge based on municipal building construction, and belongs to the technical field of building construction. The dotting device for the road and the bridge based on municipal building construction comprises a dotting box, wherein a motor output shaft penetrates through the inner wall of a machine box, extends to the outside and is sleeved with a supporting rod, the upper end of the supporting rod is rotationally connected with a movable rod through a hinge pin a rotating column is rotationally connected between an arc-shaped limiting block A and an arc-shaped limiting block B, the upper side of a rocker arm is rotatably connected with a roller B through a hinge pin, a fixed block is welded to the front end of the rotating column, and a dotting head is arranged on the bottom surface of a sleeve A. Through close fit of the structures, the device makes direct contact with the ground for dotting through the dotting head, the situations that due to spraying dotting through a spray head, dotting is dispersed, and the area is large; and adhesion is poor through spraying, the dotting effect is poor, so that the interval laying error in the later period is large, and laying is influenced are avoided, and the device improves the dotting efficiency, and improves the dotting effect.

Description

technical field [0001] The invention relates to the technical field of building construction, more specifically, to a dotting device for road bridges based on municipal building construction. Background technique [0002] During the construction of the bridge deck of the overpass, it is necessary to lay steel mesh on the road surface, and the steel bars need to be laid at a certain distance, so before laying the steel bars, it is necessary to mark the distance on the road surface. mark. The document of prior art publication number CN107268444B provides a kind of road bridge dotting device for municipal construction, and the device is provided with a driving wheel, a drive roller, a driven wheel, and a dotting device; The traveling wheel includes a traveling wheel shaft, a traveling wheel body, and a first gear; the driving wheel includes a driving wheel shaft, a driving wheel body, and a second gear; the driving roller includes an inclined slideway, and the driven wheel inc...

The document of prior art publication number CN107268444B provides a kind of road bridge dotting device for municipal construction, and the device is provided with a driving wheel, a drive roller, a driven wheel, and a dotting device; The traveling wheel includes a traveling wheel shaft, a traveling wheel body, and a first gear; the driving wheel includes a driving wheel shaft, a driving wheel body, and a second gear; the driving roller includes an inclined slideway, and the driven wheel includes a driven wheel shaft, a driven wheel body, and a dial Inserting rod; the dotting device includes a dotting shaft, a dotting bar, and a dotting probe. The device is set to do the dotting by setting the dotting pen. This insertion method is extremely unstable. Can cause the dotting pen to fall off the dotting probe, hindering the dotting work

The literature of prior art publication number CN112045652A provides a kind of dotting device based on municipal building construction for road bridges. The device is fixed with a mixing bucket by bolts on the rear top of the base, and the bottom of the mixing bucket is provided with an outlet; the base The square slot hole in the middle of the top is fixedly equipped with a spray head. Although the device has many beneficial effects, there are still the following problems: the device sprays the dots through the spray head, and the dots are scattered due to the spraying. The effect is poor, resulting in a large gap laying error in the later stage, which affects the laying. Other existing paint dotting devices need to be equipped with a separate paint liquid road drive system and a dotting lifting drive system, and it is also necessary to configure the synchronization between the two drive systems. mechanism, so the design of the dual drive system makes the overall weight larger, bulky and also reduces the reliability of the marking operation. In view of this, we propose a road and bridge marking device based on municipal construction
