Description

Technical Field

[0001] The invention relates to the technical field of surveying and mapping, and in particular to a construction surveying and mapping equipment. Background Art

[0002] In actual construction work such as foundation pits or building beams and columns, for example, the verticality of the pit wall and the size and flatness of the pit must be accurately measured. Line-laying measurement is an important part of construction, involving the positioning of buildings and the accuracy of construction measurement. Line-laying personnel need to master the use of measuring instruments and be familiar with the line-laying measurement plan. Traditional line-laying measurement is mainly carried out through the cooperation of measuring rulers and plumb bobs. The current surveying and mapping line-laying measurement equipment is not convenient for testing the horizontality of the ground during long-distance measurement. The measuring ruler is easily affected by the terrain, and there are depressions and bends, which affect the measurement accuracy. At the same time, the long-distance ground marking work adopts the traditional ink fountain line-drawing method. When marking long distances, it is easy to miss some parts, which is not convenient for auxiliary marking. At the same time, the plumb bob is not easy to fine-tune and correct during vertical measurement. The skew will affect the accuracy of the laser vertical point. During foundation pit surveying and mapping work, the bottom of the plumb bob is easily contaminated with mud, blocking the laser projection point, and the protection effect is poor.

Only relying on the method of manually lifting the ink fountain line and then releasing the marking line, the marking length is limited and the marking line is incomplete. If the line is marked multiple times, it is easy to cause the landing point of each marking to be different and not clear enough. The structure is simple to operate, and uses air pressure to mark quickly and more efficiently. Start the air pump connected to the connecting pipe 2013. At this time, the air pressure pushes the pressing column 302 downward to mark the sponge column 304, which is convenient for dipping ink on the ground.

The measuring ruler 201 is held and the plumb bob 501 is pulled to perform vertical detection on the side of the foundation pit or the beam column. If the plumb bob 501 is skewed or offset, the plumb bob 501 will drive the fine-tuning installation frame 601 to be skewed and offset together. At this time, the traction rope 401 will push the swing block 604 to drive the fixed power connection piece 603 to contact the power connection piece 6041. At this time, the prompt light 602 on the corresponding side can light up to alarm. By adopting a circle of swing blocks 604, the comprehensiveness of the detection is guaranteed.

The height of the lead pendant 501 is difficult to observe accurately, and the lead pendant 501 is easily dropped excessively. The structure of this machine can reduce the pollution rate, and the closed protective part 7 can automatically control the shielding and protection of the laser light 503, which can prevent the laser light 503 from being polluted and affecting the projection of the laser. At the same time, the closed protective part 7 used can automatically detect and control to avoid manual misoperation. This structure can realize automatic detection and control, and the length of the detection rod 702 is adjusted according to demand. When the lead pendant 501 is lowered, when the lead pendant 501 is about to approach the ground, the detection rod 702 contacts the ground first. Under the action of the gravity of the lead pendant 501, the lead pendant 501 will continue to press down, and the closed inclined block 7031 will be squeezed by the closed control slider 701. At this time, the two swinging closed frames 703 will rotate in opposite directions for shielding and protection. At this time, the closed control slider 701 will be close to the magnet 704, and magnetic positioning can be realized to ensure stable shielding.

[0041] The working principle of this embodiment is as follows: first, the staff member carries the handheld frame 103 in one hand and rotates the hand wheel on the winding roller 102 with the other hand, which can be used to wind up the measuring ruler 201, and directly lays the measuring ruler 201 on the ground, and uses the scale lines on the measuring ruler 201 to perform measurement work. After the measuring ruler 201 is laid on the ground, if the ground is flat, then the bubbles inside each horizontal cavity 2011 are located in the middle of the horizontal cavity 2011. At this time, the bubbles in the middle of the horizontal cavity 2011 cannot conduct electricity, and the corresponding circle of horizontal power-on circle 202 cannot conduct. However, once the ground is skewed, the bubbles in the middle of the horizontal cavity 2011 move upwards, and the horizontal power-on circle 202 is 202 is immersed in the conductive liquid in the horizontal cavity 2011 to achieve conduction, and the corresponding alarm light 203 is controlled to give an alarm prompt; after the measuring ruler 201 is placed on the ground, the air pump connected to the connecting pipe 2013 is started, and the air pressure pushes the pressure column 302 downward to mark the sponge column 304, which is convenient for dipping ink on the ground. At the same time, the air pressure is also used to blow out the ink inside the marking sponge column 304 through the air pressure to achieve marking on the ground. At this time, the staff can use the ink fountain to assist in the line work along the punctuation points, hold the measuring ruler 201, and pull the lead pendant 501, which can be used for vertical detection on the side of the foundation pit or the beam column. When the traction rope 401 is lifted, if the lead pendant 501 is pulled, it can be used for vertical detection on the side of the foundation pit or the beam column. The lead pendant 501 is skewed and offset, and the lead pendant 501 drives the fine-tuning installation frame 601 to be skewed and offset. At this time, the traction rope 401 will push the swing block 604, driving the fixed power connection piece 603 to contact the power connection piece 6041. At this time, the prompt light 602 on the corresponding side can light up to alarm. At this time, the staff can use a wrench to manually unscrew one circle of the positioning bolt 502, manually control the sliding adjustment disk 402 to move the displacement and adjust the center of gravity on the top of the lead pendant 501, and then tighten the positioning bolt 502 one circle for positioning; when the lead pendant 501 is lowered, when the lead pendant 501 is about to approach the ground, the detection rod 702 touches the ground first, and under the action of the gravity of the lead pendant 501 , the plumb bob 501 will continue to press down, and at this time the plumb bob 501 will drive the swinging closing frame 703 to move downward together, and the closing bevel 7031 will be squeezed by the closing control slider 701, and the two swinging closing frames 703 will rotate inward, and the bottom of the two swinging closing frames 703 will block the laser light 503, and the closing control slider 701 will be close to the magnet 704, so as to realize magnetic positioning and ensure stable blocking, and when the laser light 503 needs to be used again to obtain the marking point, the staff needs to manually pull down the closing control slider 701 to release the squeezing of the closing bevel 7031 to ensure that the lens of the laser light 503 is clean and free of impurities and scratches.
