Description

Technical Field

[0001] This utility model relates to the field of construction surveying and setting out technology, and more specifically, it relates to a construction surveying and setting out device. Background Technology

[0002] Foundation pit engineering is a systematic project that integrates geological engineering, geotechnical engineering, structural engineering and geotechnical testing technology. During the construction of foundation pit engineering, it is necessary to excavate foundation pit pile holes. Before excavating the foundation pit pile holes, the construction workers will measure the position of the center of the foundation pit pile holes on the ground according to the drawings, and then spread lime to mark the corresponding size range. Then the excavation equipment will excavate the soil according to the spread lime. During the process of spreading lime, people will use construction surveying and setting-out devices.

[0003] The existing construction surveying and setting-out device includes a base, a servo motor is fixedly connected to the top surface of the middle part of the base, a connecting rod is fixedly connected to the top of the servo motor, and a mortar bucket is connected to the connecting rod through a corresponding adjustment structure. The servo motor drives the connecting rod and the mortar bucket to rotate, and the lime is sprinkled onto the ground through the discharge valve pipe on the mortar bucket, marking the area of ​​the circular foundation pit pile hole on the ground.

[0004] However, the existing construction surveying and setting-out device is not convenient for moving the connecting rod to the middle position of the measured and marked foundation pit, which causes the area of ​​lime to be sprinkled to deviate, resulting in poor accuracy of lime sprinkling and setting-out. Furthermore, since the servo motor is located at the top center of the base, the lime bucket will rotate on the upper side of the base during the lime sprinkling and setting-out process, causing some lime to be sprinkled on the base, resulting in poor integrity of the lime sprinkling and setting-out area. The lime falling on the base leads to waste of lime, and the lime on the base also needs to be cleaned by people, increasing the workload. Utility Model Content

Through the action of the compression spring, the compression spring pushes the fixing ring and the locking pin to move closer to the locking slot, and the locking pin is inserted into the corresponding locking slot to fix the square tube.

[0035] In summary, when using the overall equipment:

[0036] First, take out the measuring tool from inside the placement slot. Use the measuring tool to measure the position of the center of the foundation pit pile hole on the ground according to the drawing, and mark it. Roll the roller on the ground to move the construction measurement and layout device to the vicinity of the marked position to be laid out. Then start the second servo motor, which drives the adjusting screw to rotate. The rotation of the adjusting screw causes the second convex seat to slide inside the second convex groove. The second convex seat drives the sliding plate, support plate, horizontal plate and mortar bucket to move, so that the mortar bucket moves to one side of the base.

[0037] Then, the clamping post is moved outward by pulling the pull plate, and the clamping post is separated from the clamping groove. Then, the height of the positioning cone is adjusted by sliding the square tube on the outside of the square post, and the positioning cone is moved to a position close to the ground. The pull plate is released, and the compression spring pushes the fixing ring and the clamping post to the side closer to the clamping groove, and the clamping post is inserted into the corresponding clamping groove. The square tube is fixed, and then the construction surveying and setting-out device is pushed to move so that the positioning cone corresponds to the middle position of the marked foundation pit pile hole.

[0038] Then, loosen the fixing screw to separate the side end of the fixing screw from the side wall of the first convex groove. Then, slide the first convex seat inside the first convex groove. The first convex seat drives the ash bucket to move. According to the radius of the foundation pit pile hole marked on the drawing, align the positioning column with the corresponding scale value on the scale line. At this time, the distance between the central axis of the discharge valve pipe and the positioning cone is the radius of the foundation pit pile hole. Then, tighten the fixing screw to make the side end of the fixing screw abut against the side end of the first convex groove, fixing the first convex seat and the ash bucket. Then, add lime into the ash bucket through the feeding port. Then, open the valve on the discharge valve pipe. The lime inside the ash bucket is sprinkled onto the ground through the discharge valve pipe. At the same time, the first servo motor drives the rotating plate and the ash bucket to rotate at an appropriate speed, thereby completely and accurately drawing the range of the foundation pit pile hole.
