DETAILED DESCRIPTION

[0041] The following will be combined with the Figure 1 To the attached Figure 5 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort shall fall within the scope of protection of the present invention.

[0042] It should be noted that if there are any directions involved in the embodiments of the present invention, they shall be based on the directions shown in the drawings, such as front and back. Figure 1 The specific Figure 1 The left side is the front, Figure 1 The right side is the back; at the same time Figure 2 As shown in the figure, the left-right direction is roughly the horizontal direction, and the up-down direction shown in the figure is the vertical direction. If a specific posture changes, the directional indication will also change accordingly.

[0043] Reference Figure 1 - Figure 13 As shown, the present invention provides a construction engineering flatness detection device, comprising two mounting seats 1, a fixed rod 3 is installed between the two mounting seats 1, a moving member 7 is slidably provided on the fixed rod 3, a drawing component 5 is provided on the moving member 7, an air storage component 2 is provided between the drawing component 5 and the two mounting seats 1, and an adsorption component 6 is installed between the air storage component 2 and the two mounting seats 1;

[0044] The gas storage assembly 2 includes a storage box 201. A mounting tube 202 is mounted on one end of the side wall of the storage box 201. The mounting tube 202 connects the inside and outside of the storage box 201. A ring 209 is mounted on the side of the mounting tube 202 away from the storage box 201. A spring 210 is mounted on the side of the ring 209 close to the storage box 201. A sealing bead 211 is mounted on the side of the spring 210 away from the ring 209. The side wall of the mounting tube 202 is symmetrically provided with through grooves 208 on one side of the inner cavity of the storage box 201. The design of the through grooves 208 facilitates the entry of external airflow into the storage box 201.

[0045] A conduit 213 is installed on the side of the bottom surface of the inner cavity of the savings box 201 near the mounting tube 202. A second ring 214 is installed on the top surface of the inner cavity of the conduit 213. A second spring 215 is installed on the bottom surface of the second ring 214. A closing tube 216 is installed at the bottom end of the second spring 215. The bottom surface of the closing tube 216 is closed, and a plurality of chute grooves 217 are evenly opened on the side wall of the closing tube 216. A connecting tube 203 is installed below the outer wall of the conduit 213. A hose 1 205 is installed below the inner cavity of the connecting tube 203. The hose 1 205 is connected to the drawing component 5.

[0046] A sliding plate 1 207 is provided inside the savings box 201 for sliding movement. Pull rope 1 206 and pull rope 2 204 are connected to both sides of the sliding plate 1 207. Pull rope 1 206 and pull rope 2 204 both pass through the side wall of the savings box 201 and extend to the outside of the savings box 201.

[0047] In this embodiment, pulling the second pull rope 204 drives the positioning plate 703, the moving frame 701, the drawing assembly 5, the first pull rope 206 and the first sliding plate 207 to move. Subsequently, the first sliding plate 207 moves away from the mounting cylinder 202. As the first sliding plate 207 moves, the space between the first sliding plate 207 and the mounting cylinder 202 becomes larger. At this time, the pressure in the storage box 201 decreases. Under the action of atmospheric pressure, the external air presses against the sealing bead 211 and overcomes the tension of the first spring 210. At this time, the external air enters the storage box 201.

[0048] Pulling the pulling rope 206 drives the positioning plate 703, the moving frame 701, the drawing component 5, the pulling rope 204 and the sliding plate 207 to move. At this time, the sliding plate 207 moves in the opposite direction, and the sliding plate 207 compresses the air between the sliding plate 207 and the storage box 201. At this time, the closing bead 211 will contact the inner wall of the mounting tube 202 under the action of the air pressure between the sliding plate 207 and the storage box 201. At the same time, the closing tube 216 will overcome the pulling force of the spring 215 under the action of the air pressure between the sliding plate 207 and the storage box 201, and move downward. The airflow of the storage box 201 passes through the conduit 213 and the slide 217, and is finally sprayed by the hose 205 to the forward direction of the roller 504.

[0049] In a further embodiment, referring to Figure 1 - Figure 11 The storage box 201 is installed between the two mounting seats 1, and the mounting cylinder 202 is located at one end of the inner cavity of the storage box 201 and is installed with a circular plate 212;

[0050] A plurality of arc-shaped plates 218 are evenly installed below the inner cavity of the conduit 213, and a plurality of corresponding sliding plates are arranged inside the sliding grooves 217;

[0051] In this embodiment, the arc plate 218 limits the vertical movement distance of the sealing cylinder 216, and the circular plate 212 limits the movement distance of the sealing bead 211, thereby preventing the sealing cylinder 216 and the sealing bead 211 from excessive movement.

[0052] In a further embodiment, referring to Figure 1 - Figure 4The movable member 7 includes a movable frame 701, which is slidably arranged on the fixed rod 3. A positioning plate 703 is symmetrically provided on one side of the movable frame 701 close to the gas storage component 2. A connecting block 702 is installed between the two positioning plates 703. The drawing component 5 is slidably arranged on the connecting block 702. One positioning plate 703 is connected to a pull rope 1 206, and the other positioning plate 703 is connected to a pull rope 2 204. The pull rope 1 206 and the pull rope 2 204 are respectively slidably installed on the mounting seat 1. A rubber protective layer is provided on the outside of the pull rope 1 206 and the pull rope 2 204, so that the connection between the pull rope 1 206 and the pull rope 2 204 and the storage box 201 remains airtight.

[0053] In this embodiment, pulling the pull rope 1 206 or the pull rope 2 204 can drive the movable member 7 to slide on the fixed rod 3, thereby achieving the effect of the drawing pen 508 on the drawing component 5 drawing the ground flatness circuit diagram on the paper.

[0054] In a further embodiment, referring to Figure 1 - Figure 9 The drawing component 5 includes a sliding rod 501, which is slidably arranged in the connecting block 702. A roller 504 is provided on the bottom surface of the sliding rod 501. A positioning block 502 is installed below the side wall of the sliding rod 501. The positioning block 502 is connected to the hose 205.

[0055] A sliding frame 503 is slidably provided on the side wall of the sliding rod 501. A plurality of plywood 505 is evenly arranged on the top and bottom surfaces of the sliding frame 503. The plywood 505 is provided with grooves 506. Rubber bands 509 are sleeved between the grooves 506 on the plurality of plywood 505. The plywood 505 is provided with anti-slip grooves on the side close to the sliding rod 501.

[0056] A rubber block 507 is installed on the side of the sliding frame 503 close to the savings box 201, and a drawing pen 508 is inserted into the rubber block 507;

[0057] In this embodiment, when pulling the second pull rope 204 to store gas in the storage box 201, the sliding rod 501 should be pulled to slide upward to avoid contact between the roller 504 and the ground, thereby reducing wear on the roller 504;

[0058] The rubber block 507 is made of hard rubber, and the drawing pen 508 is interference-fitted with the rubber block 507 . This allows the drawing pen 508 to remain in its inserted position regardless of its length. Furthermore, by controlling the insertion length of the drawing pen 508 in the rubber block 507 , it is possible to control whether the drawing pen 508 is in contact with the drawing paper.

[0059] The sliding frame 503 and the sliding rod 501 can slide relative to each other to adjust the positions of the sliding frame 503, the rubber block 507, and the drawing pen 508. After adjustment, the rubber band 509 is tightened between the grooves 506 on the multiple clamping plates 505, so that the grooves 506 are in close contact with the sliding rod 501, thereby increasing friction and limiting the position of the sliding frame 503.

[0060] Furthermore, when the moving member 7 drives the drawing component 5 to move, the drawing pen 508 in the drawing component 5 will draw a ground flatness circuit diagram on the paper.

[0061] In a further embodiment, referring to Figure 1 - Figure 13 The adsorption assembly 6 includes a mounting box 601, which is arranged between the two mounting seats 1. A positioning frame 603 is slidably provided in the mounting box 601, and a plurality of moving blocks 605 are evenly arranged below the side of the positioning frame 603 close to the mounting box 601;

[0062] A connection box 602 is installed below the outer wall of the installation box 601 away from the moving member 7. A moving block 605 slides through the connection box 602. The moving block 605 is located on the left and right side walls of the inner cavity of the connection box 602. Limit blocks 610 are respectively installed.

[0063] A fixing box 606 is installed on the bottom surface of the savings box 201;

[0064] A flow guide tube 604 is provided between the fixing box 606 and the connection box 602 , and the flow guide tube 604 communicates with the inner cavity of the connection box 602 and the fixing box 606 ;

[0065] A second sliding plate 609 is slidably mounted in the connection box 602. A movable rod 607 is mounted on the side of the second sliding plate 609 away from the guide tube 604. A movable groove 4 is formed on the bottom surface of the storage box 201. The movable rod 607 is slidably mounted in the movable groove 4. A connecting rope 608 is connected to the movable rod 607. The connecting rope 608 is connected to the first sliding plate 207 away from the movable rod 607.

[0066] In this embodiment, during the use of the device, the mounting base 1 is first placed on the ground, and paper is placed between the positioning frame 603 and the mounting box 601. Then, the pull rope 204 is pulled to drive the sliding plate 1 207 to move. The moving sliding plate 1 207 will resist the moving rod 607, so that the moving rod 607 pulls the sliding plate 2 609. When the sliding plate 2 609 moves, the connecting space between the connecting box 602, the guide tube 604 and the fixed box 606 becomes larger. At this time, the air pressure inside the three is small. Under the action of atmospheric pressure, the moving block 605 will move with the positioning frame 603 toward the direction of the connecting box 602, thereby pressing and positioning the paper.

[0067] In a further embodiment, referring to Figure 4 and Figure 13 A closing plate 8 is installed below the side of the sliding plate 207 away from the moving rod 607, and the bottom surface of the closing plate 8 is in contact with the bottom surface of the inner cavity of the storage box 201;

[0068] In this embodiment, when the sliding plate 207 pushes the moving rod 607 , the closing plate 8 closes the moving groove 4 , preventing the savings box 201 from communicating with the outside through the moving groove 4 .

[0069] The working principle of the present invention is as follows: when using the device, first place the mounting base 1 on the ground, and put paper between the positioning frame 603 and the mounting box 601;

[0070] Then, the pull rope 204 is pulled to drive the positioning plate 703, the moving frame 701, the drawing assembly 5, the pull rope 1 206 and the sliding plate 1 207 to move. Then, the sliding plate 1 207 will move in the direction away from the installation cylinder 202. As the sliding plate 1 207 moves, the space between the sliding plate 1 207 and the installation cylinder 202 will become larger. At this time, the pressure in the storage box 201 decreases. Under the action of atmospheric pressure, the external air will press against the sealing bead 211 and overcome the tension of the spring 1 210. At this time, the external air enters the storage box 201.

[0071] As the sliding plate 1 207 continues to move, the sliding plate 1 207 will come into contact with the moving rod 607, causing the moving rod 607 to pull the sliding plate 2 609. When the sliding plate 2 609 moves, the space connecting the connection box 602, the guide tube 604, and the fixed box 606 becomes larger. At this time, the air pressure inside the three is low. Under the action of atmospheric pressure, the moving block 605 and the positioning frame 603 will move toward the connection box 602, thereby pressing and positioning the paper.

[0072] When drawing, pull the pull rope 1 206 to move the positioning plate 703, the moving frame 701, the drawing component 5, the pull rope 204 and the sliding plate 1 207, and use the drawing component 5 to draw a ground flatness diagram on the paper. At this time, the sliding plate 1 207 moves in the opposite direction, and the sliding plate 1 207 compresses the air between the sliding plate 1 207 and the storage box 201. At this time, the sealing bead 211 will contact the inner wall of the installation cylinder 202 under the action of the air pressure between the sliding plate 1 207 and the storage box 201, and the sealing cylinder 216 will be closed. Under the action of the air pressure between the sliding plate 1 207 and the storage box 201, the pulling force of the spring 215 is overcome and the sliding plate 1 moves downward. The airflow from the storage box 201 passes through the duct 213 and the chute 217, and is finally ejected by the hose 1 205 in the direction of the roller 504. This can simultaneously draw a ground flatness route map and blow away the dust on the moving path of the roller 504, reducing the impact of the dust on the ground on the detection results, thereby improving the accuracy of the ground flatness detection and extending the service life of the roller 504.

[0073] And as the sliding plate 207 continues to move, when the sliding plate 207 is about to move to the end, the connecting rope 608 between the sliding plate 207 and the moving rod 607 will be tightened, and then the sliding plate 207 will pull the moving rod 607 and the sliding plate 2 609 to move through the connecting rope 608, thereby reducing the connecting space between the connecting box 602, the guide tube 604 and the fixed box 606, thereby moving the moving block 605 and the positioning frame 603 in the direction away from the installation box 601, thereby releasing the limit on the paper after the drawing is completed, achieving the effect of quickly locating and releasing the positioning of the paper used to draw the ground flatness line map, and improving the stability of the paper during drawing.
