Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building construction reference line setting device. Background Art

[0002] Before construction begins, it's necessary to lay out the construction baseline. Setting out construction baselines is a crucial and complex technical task. One of the primary purposes of setting out the baselines is to establish a reference horizontal plane, which serves as a base for basic construction work like wall construction and paving. However, the uneven ground at construction sites makes it difficult to place a level to establish a baseline. Therefore, we've developed a new device for setting out construction baselines. Utility Model Content

[0003] The main purpose of the utility model is to provide a construction baseline setting device, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The cam is provided with a plurality of gears, and the gears are connected with the gears of the lifting link, and the gears are connected with the gears of the lifting link, and the gears are connected with the gears of the lifting link.

[0006] Preferably, the interior of the installation box is communicated with the interior of the movable groove.

[0007] Preferably, the gear column and the rack are meshed and connected together, and the outer surface of the gear column does not contact the inner surface of the movable groove.

[0008] Preferably, the motor and the installation box are fixedly connected together.

[0009] Preferably, the prompt device includes a fixing frame, a center line is provided in the middle of the inner rear wall of the fixing frame, a movable rod is fixedly installed inside the fixing frame, a movable ring is provided on the outer surface of the movable rod, and a pointer is provided on the rear of the outer surface of the movable ring.

[0010] Preferably, the width of the pointer is consistent with the width of the center line.

[0011] Preferably, the position of the pointer corresponds to the position of the center line in front and back.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Use the universal wheel to move the entire frame to the position where the defense line is required and fix it. Observe the position of the pointer on the movable ring. If the pointer is on the left or right side of the center line, it means that the fixed seat is tilted with the left lower and the right higher, or the left higher and the right lower. According to the actual situation, open the two telescopic cylinders on the left or the right through the controller to drive the left or right side of the fixed plate to move upward until the pointer corresponds to the position of the center line. At this time, the fixed plate is in a balanced state as a whole, which is convenient for laying out the line later.

[0014] 2. Turn on the motor through the controller, and the motor drives the gear column to rotate. The gear column is engaged with the rack, which makes it easy to drive the sliding column to move upward, and then makes it easy to drive the placement plate to move upward until it is adjusted to the appropriate height. By placing the level on the placement plate, you can lay out the line. It is convenient to adjust the height of the placement plate according to needs, and it is convenient to lay out lines at different heights, which is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
