Abstract

The invention discloses a foundation pit construction line marking device. The foundation pit construction line marking device comprises a control lever. A handle is connected with the upper end of the control lever. The lower end of the control lever is connected with a tail wheel carrier. The lower end of the tail wheel carrier is connected with a tail wheel shaft. The tail wheel shaft is rotationally connected with a tail wheel through a tail wheel bearing. The upper end of the tail wheel carrier is connected with a connecting rod. The other end of the connecting rod is connected with a sleeve. Adjustable bolts are connected with the circumferential surfaces of the two ends of the sleeve respectively through threads. The front end of each adjustable bolt can be screwed into the sleeve.The two ends of the sleeve are inserted into front wheel shafts respectively. The front wheel shafts can axially move in the sleeve. The end of each front wheel shaft is rotationally connected with aline marking rolling wheel through a front wheel bearing. The line marking rolling wheels are hollow and can contain powdery materials inside. A filling opening is formed in the outer side face of each line marking rolling wheel. An openable door is arranged at the position of each filling opening. A plurality of discharge holes are evenly distributed in the circumferential surface of each line marking rolling wheel in the circumferential direction. The foundation pit construction line marking device is simple in structure and convenient to use, and can mark two control lines at one time, andtherefore, the labor intensity is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a marking device for foundation pit construction control lines. Background technique [0002] In building construction, it is often necessary to excavate foundation pits, and it is necessary to delineate the excavation control line before excavation. For this control line, most construction companies currently delineate it manually, that is: two operators in the The two ends of the tape are tightened, and another operator sprinkles lime on the ground bit by bit along the tape. This scribing method is time-consuming, labor-intensive, labor-intensive, and inefficient, especially for ground with a certain slope, this manual scribing is just more strenuous. Contents of the invention [0003] In order to solve the above existing problems, the present invention proposes a control line marking device for foundation pit construction. The device is simple in structure, ...
