Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a marking and line marking device used in building construction. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of buildings, encompassing a series of complex and orderly procedures from foundation construction to the erection of the main building structure and interior and exterior decoration. In building construction, preliminary work such as site leveling and foundation excavation must be carried out first to build a solid foundation for the building. Subsequently, through procedures such as steel bar binding, formwork erection, and concrete pouring, the main framework of the building is gradually constructed.

[0003] When marking lines in construction, the line marking machine is a key piece of equipment. However, in actual operation, there is a problem that affects the marking effect. The line marking machine is usually equipped with pulleys to facilitate the movement of the equipment, but these pulleys have a deflection function. When the workers operate the line marking machine to carry out the marking work, because the pulleys can deflect, the actual marking trajectory is very likely to deviate from the pre-planned marking line. The originally planned marking position and direction cannot be accurately achieved due to the deflection of the pulleys.

[0004] Therefore, a marking and line marking device for building construction is proposed. Utility Model Content

Figures 1-4This utility model provides a technical solution: a marking and line marking device for building construction, including a mounting base 1, a push handle 2 fixedly mounted on the left end of the mounting base 1, a pulley frame 3 below the mounting base 1, four pulley frames 3 evenly arranged, a connecting mechanism 4 above the pulley frames 3, and a line marking mechanism 5 inside the connecting mechanism 4;

[0026] The connecting mechanism 4 includes a connecting part and a locking part;

[0027] The scribing mechanism 5 includes a drive unit and a scribing unit.

[0028] The connecting part includes a lifting frame 41, two lifting frames 41 are arranged at the front and rear, and the two lifting frames 41 are located on the front and rear sides of the mounting base 1 respectively. A connecting frame 42 is fixedly arranged on the top surface of the lifting frame 41, and two connecting frames 42 are arranged on the left and right sides.

[0029] A hydraulic cylinder 43 is fixedly installed on the right end of the top surface of the mounting base 1. The upper end of the output shaft of the hydraulic cylinder 43 is fixedly connected to the right connecting frame 42. A positioning frame 45 is fixedly installed on the left end of the top surface of the mounting base 1. A positioning plate 44 is installed inside the positioning frame 45.

[0033] Furthermore, in this embodiment, the output shaft of the hydraulic cylinder 43 extends and retracts, driving the right connecting frame 42 to move up and down. The movement of the connecting frame 42 will drive the lifting frame 41 to rise and fall. When the lifting frame 41 rises and falls, it will drive the rotating frame 47 and the locking frame 49 to rotate around the hinge point with the connecting seat 46, so that the locking frame 49 and the lower end of the bearing seat 410 are locked with the inner wall of the locking frame 49, thereby preventing the bearing seat 410 from rotating and preventing the pulley frame 3 at the lower end of the bearing seat 410 from deflecting.

The connecting pump 59 delivers the paint to the marking head 510, and the marking head 510 marks lines on the ground.

[0038] Furthermore, in this embodiment, the motor 53 drives the threaded rod 54 to rotate, causing the movable seat 55 to move smoothly along the threaded rod 54, thereby driving the marking head 510 to move to the predetermined marking area, ensuring the straightness and accuracy of the marking, and meeting the strict requirements of building construction for marking lines.
