Description

Technical Field

[0001] The utility model relates to the technical field of line drawing devices, in particular to a line drawing detection device for construction services. Background Art

[0002] Construction is a production activity carried out by people using various building materials and machinery to build various building products within a certain space and time according to a specific design blueprint. It includes the entire production process from construction preparation and groundbreaking to project completion and acceptance. Pipes are often used in the construction process. Before use, the pipes need to be inspected for quality. Because pipes are usually long, they need to be cut into sections. When cutting the pipes, workers need to measure the pipes with a ruler and then use a marker to mark the length of the pipe to be cut. This operation is very cumbersome and the marking accuracy is not high, which affects the cutting effect.

[0003] Patent CN220179320U proposes a line drawing detection device for construction engineering services. Through the setting of the line drawing mechanism, the driving motor drives the connecting shaft and the socket gear to rotate, the socket gear drives the ring gear to rotate, and the rotation of the ring gear drives the protruding slide to slide on the slide groove. At the same time, when the ring gear rotates, it drives the electric telescopic rod 2 and the brush to rotate, thereby drawing lines on the pipeline. The servo motor drives the threaded rod to rotate, and the threaded rod drives the threaded sleeve to move, and then drives the support frame and the sleeve to move as a whole, and adjusts the position of the brush. The position of the brush movement is synchronized with the position of the indicator plate. The position of the line drawing can be adjusted as needed, and the pipeline of a specific length can be easily cut out, which is convenient for unified detection and can automatically draw lines on the pipeline.

[0004] Although the above solution can realize automatic marking of pipe fittings, it is not suitable for marking pipes of different diameters. At the same time, the device is large and inconvenient to carry. A flat area needs to be found at the construction site for marking, so its applicability is low. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a line detection device for construction services to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Through two triangular seats and two sets of positioning components, it can be suitable for the installation of pipes of different diameters. According to the scale of the tape measure after unfolding, the position of the line drawing pen on the side frame is moved to draw the position where the line needs to be drawn, and the range of the line drawing is preliminarily measured. The intercepted pipe can be measured again in the subsequent process to detect the error in the line drawing distance. The device is convenient to fold, store and carry.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a line drawing detection device for construction services, including a triangular seat, the triangular seat is provided with two groups, and the top inner surface of the two groups of triangular seats is provided with a positioning assembly, the positioning assembly includes a storage frame, and the two sides of the storage frame are slidably inserted with insertion strips, the two insertion strips respectively extend from the top and bottom of the storage frame, and contact blocks are fixed on the protruding ends of the insertion strips, and the contact blocks can be squeezed and contacted with the top and bottom inner walls of the pipe to be marked. The bottoms of the two groups of triangular seats are provided with a measuring assembly, and the measuring assembly includes a tape measure, one end of the tape measure is fixed to the bottom of one triangular seat, and the other end of the tape measure slides through the other triangular seat, and one end of the tape measure is located between the positioning assembly and the triangular seat and is provided with a line drawing assembly, the line drawing assembly includes a horizontal frame, a movable groove is opened on the surface of the horizontal frame, and a movable block is slidably connected in the movable groove, the outer surface of the movable block is rotatably mounted with a side frame through a damping shaft, and a line drawing pen is installed on the surface of the side frame.

[0007] Furthermore, the positioning assembly also includes a gear. A gear is installed inside the storage frame between the two insertion strips and is rotatably installed through a bearing. A rack is fixed on the inner side of the insertion strip, and the gear is meshed with the rack. A connecting column is fixed at the center of the gear, and the connecting column passes through the storage frame and is rotatably installed on the top of the triangular seat through a bearing.

[0008] Furthermore, the line drawing assembly also includes a rotating disk, and the rotating disk is fixed at the position of the horizontal frame corresponding to the connecting column, and the rotating disk is rotatably sleeved on the surface of the connecting column through a bearing.

[0009] Furthermore, a screw is rotatably installed inside the movable groove through a bearing, and the movable block is threadedly sleeved on the surface of the screw.

[0010] Furthermore, a slider is slidably sleeved on the surface of the side frame corresponding to the position of the liner pen, and the liner pen is fixed on the surface of the slider.

[0011] Furthermore, a card frame is provided on one side of the slider, and a pressure plate is provided inside the card frame on the side of the slider. A locking bolt is threadedly inserted into the outer end of the card frame of the sliding frame. One end of the locking bolt is rotatably connected to the pressure plate through a bearing, and the pressure plate can be squeezed into contact with the surface of the side frame.

[0012] Furthermore, the measuring component also includes a sliding frame, which is slidably connected to the surface of the tape measure, and a connecting frame is slidably connected to the top of the sliding frame. The connecting frame is L-shaped, and the vertical end of the connecting frame is slidably connected to the back of the slider. A slot is provided on the back of the slider corresponding to the vertical end of the connecting frame.

[0013] Furthermore, a winding seat is installed on the outer surface of the bottom of the triangular seat at one end of the measuring tape, and the measuring tape is wound on the winding seat through a rotating shaft and a torsion spring.

[0014] Beneficial effects of the utility model:

[0015] 1. The utility model has a connecting frame and a marking pen on the same tangent plane, so the vertical end of the connecting frame is slidably inserted into the slot of the slider. Therefore, when the slider is slid along the side frame and the marking pen moves, the connecting frame and the sliding frame can slide synchronously along the measuring tape. When the drawing position is determined, the locking bolt is rotated to drive the pressure plate to squeeze the surface of the side frame, fixing the position of the slider, maintaining the stability of the marking pen when it makes a circular rotation, and preventing the drawing direction from deviating.

[0016] 2. The utility model records the two marking positions of a section of pipe manually to obtain the distance, and then compares the measurement results of the length of the cut pipe separately to obtain the error size. The card slot is in a semi-open form. Therefore, when the slider and the side frame rotate together with the cross frame, the slider squeezes the connecting frame, so that the vertical end of the connecting frame is separated from the card slot. The connecting frame will not interfere with the subsequent step of drawing the line around the pipe with the marking pen. After the line is drawn, the device is retracted, the tape measure is reeled in by the reel-up seat, and the two triangular seats are close to each other, which reduces the size of the device and is convenient to carry.

[0017] 3. The utility model rotates the screw, and the moving block cooperates with the screw thread to slide along the inside of the moving groove. After the side frame is unfolded and perpendicular to the moving block, the position of the drawing pen can be adjusted so that the pen tip contacts the surface of the pipe, thereby facilitating line drawing. The rotating connection between the side frame and the moving frame facilitates subsequent folding and storage.

[0018] 4. The utility model drives the gear to rotate by rotating the connecting column, and the racks on both sides engage with the gear to drive the two inserts to extend synchronously in opposite directions, and contact the inner walls of the top and bottom of the pipe through the contact block, and can keep the position of the connecting column on the central axis of the pipe. Because the cross frame is connected to the connecting column through the rotating disk, the position of the cross frame will not be affected when the connecting column rotates. At the same time, the cross frame can keep rotating on the central axis of the pipe to guide the rotation path of the marker. In addition, this structure can meet the requirement that the two sets of triangular frames do not have to be placed on a flat ground. It is only necessary to ensure that there is space at the bottom of the pipe to accommodate the marker and the side frame. The marker will always keep moving along the cross-section of the pipe.

[0019] 5. Compared with the prior art, the present invention can be applied to the installation of pipes of different diameters through two triangular seats and two sets of positioning components. According to the scale of the unfolded tape measure, the position of the marking pen on the side frame is moved to draw lines at the positions where lines are required, and a preliminary measurement of the range of the lines is performed. The intercepted pipes can be measured again in the subsequent process to detect the error in the line distance. The device is convenient to fold, store and carry. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] See also Figures 1 to 6The utility model provides a technical solution: a line drawing detection device for construction services, including a triangular seat 1, the triangular seat 1 is provided with two groups, and a positioning component 3 is provided on the top inner surface of the two groups of triangular seats 1, the positioning component 3 includes a receiving frame 31, and insertion strips 32 are slidably inserted on both sides of the receiving frame 31. The two insertion strips 32 pass through the top and bottom of the receiving frame 31 respectively, and a contact block 33 is fixed on the passing end of the insertion strip 32. The contact block 33 can be squeezed and contacted with the top and bottom inner walls of the pipe to be marked. A measuring component 4 is provided at the bottom of the two groups of triangular seats 1, and the measuring component 4 includes a tape measure 41. One end of the tape measure 41 is fixed to the bottom of the triangular seat 1 on one side, and the other end of the tape measure 41 slides through the triangular seat 1 on the other side. One end of 41 is located between the positioning component 3 and the triangular seat 1, and a drawing component 2 is provided. The drawing component 2 includes a horizontal frame 24, a movable groove 25 is opened on the surface of the horizontal frame 24, and a movable block 27 is slidably connected in the movable groove 25. The outer surface of the movable block 27 is rotatably installed with a side frame 21 through a damping shaft, and a drawing pen 23 is installed on the surface of the side frame 21. When using the device, the two triangular seats 1 are unfolded to the two ends of the pipeline, and the tape measure 41 of the measuring component 4 is unfolded synchronously and fixed to the two ends of the pipeline through the positioning component 3. The pipeline surface is drawn around the central axis of the pipeline through the drawing component 2, and the distance of the lines at both ends of the pipeline to be intercepted is recorded, and the length of the intercepted pipeline is measured by subsequent measuring equipment to detect the error value of the tape measure 41.

[0029] In this embodiment, the positioning assembly 3 also includes a gear 36. The interior of the storage frame 31 is located between the two insertion strips 32 and a gear 36 is rotatably installed through a bearing. A rack 35 is fixed to the inner side of the insertion strip 32, and the gear 36 is meshed with the rack 35. A connecting column 34 is fixed at the center of the gear 36, and the connecting column 34 passes through the storage frame 31 and is rotatably installed on the top of the triangular seat 1 through a bearing. The drawing assembly 2 also includes a rotating disk 28. The horizontal frame 24 is fixed with a rotating disk 28 at a position corresponding to the connecting column 34, and the rotating disk 28 is rotatably sleeved on the surface of the connecting column 34 through a bearing. Rotating the connecting column 34 drives the gear 36 to rotate, and the racks 35 on both sides and the gear 36 are connected. The engagement drives the two insertion strips 32 to extend synchronously in opposite directions, contacting the top and bottom inner walls of the pipe through the contact block 33, and can keep the position of the connecting column 34 on the central axis of the pipe. Because the cross frame 24 is connected to the connecting column 34 through the rotating disk 28, the rotation of the connecting column 34 will not affect the position of the cross frame 24. At the same time, the cross frame 24 can keep rotating on the central axis of the pipe to guide the rotation path of the marker 23. In addition, this structure can meet the requirement that the two sets of triangular frames do not necessarily have to be placed on a flat ground. It is only necessary to ensure that there is space at the bottom of the pipe to accommodate the marker 23 and the side frame 21. The marker 23 will always keep moving along the cross-section of the pipe.

[0030] In this embodiment, a screw 26 is rotatably installed inside the movable groove 25 through a bearing, and a movable block 27 is threadedly sleeved on the surface of the screw 26. A slider 22 is slidably sleeved on the surface of the side frame 21 corresponding to the position of the marker 23, and the marker 23 is fixed on the surface of the slider 22. The screw 26 is rotated, and the movable block 27 and the screw 26 are threadedly matched to slide along the inside of the movable groove 25. After the side frame 21 is unfolded and perpendicular to the movable block 27, the position of the marker 23 can be adjusted so that the tip of the pen contacts the surface of the pipe, thereby facilitating line drawing. The rotating connection between the side frame 21 and the movable frame facilitates subsequent folding and storage.

[0031] In this embodiment, a card frame is provided on one side of the slider 22, and a pressure plate 210 is provided inside the card frame on the side of the slider 22. A locking bolt 211 is threadedly inserted into the outer end of the card frame of the sliding frame 42. One end of the locking bolt 211 is rotatably connected to the pressure plate 210 through a bearing, and the pressure plate 210 can be squeezed into contact with the surface of the side frame 21. The measuring component 4 also includes a sliding frame 42. The sliding frame 42 is slidably sleeved on the surface of the tape measure 41, and a connecting frame 43 is slidably inserted into the top of the sliding frame 42. The connecting frame 43 is L-shaped. The vertical end of the connecting frame 43 is slidably plugged into the back of the slider 22. A slot 29 is provided on the back of the slider 22 corresponding to the vertical end of the connecting frame 43. A winding seat 44 is installed on the outer surface of the bottom of the triangular seat 1 at one end of the tape measure 41, and the tape measure 41 is wound on the winding seat 44 through a rotating shaft and a torsion spring. After the triangular seat 1 is unfolded to the two ends of the pipe, it is placed on the ground. At this time, the tape measure 41 will also be stretched and unfolded, and the winding seat 44 will automatically unwind. The sliding frame 42 is slidably sleeved on the tape measure 41, and is connected to the drawing pen 23 through the connecting frame 43. On the same cutting plane, the vertical end of the connecting frame 43 slides and is inserted into the slot 29 of the slider 22. Therefore, when the slider 22 is slid along the side frame 21 and the drawing pen 23 moves, the connecting frame 43 and the sliding frame 42 can slide synchronously along the tape measure 41. When the drawing position is determined, the locking bolt 211 is rotated to drive the pressure plate 210 to squeeze the surface of the side frame 21, fix the position of the slider 22, maintain the stability of the drawing pen 23 when it rotates in a circle, avoid the deviation of the drawing direction, and manually record the two drawing positions of a section of pipe. , get the distance, and then compare the measurement results of the intercepted pipe length separately to get the error size. The slot 29 is in a semi-open form. Therefore, when the slider 22 and the side frame 21 rotate together with the cross frame 24, the slider 22 squeezes the connecting frame 43, so that the vertical end of the connecting frame 43 is separated from the slot 29. The connecting frame 43 will not interfere with the subsequent step of the marking pen 23 drawing a line around the pipe. After the line drawing is completed, the device is retracted, and the tape measure 41 is reeled in by the reeling seat 44. The two triangular seats 1 are close to each other, which reduces the volume of the device and is convenient to carry.

[0032] When using the device, the two triangular seats 1 are unfolded to the two ends of the pipe, the tape measure 41 of the measuring assembly 4 is unfolded synchronously, the connecting column 34 is rotated to drive the gear 36 to rotate, and the racks 35 on both sides are engaged with the gear 36 to drive the two insertion strips 32 to extend synchronously in opposite directions, and contact the top and bottom inner walls of the pipe through the contact block 33, and the position of the connecting column 34 can be kept on the central axis of the pipe. Because the horizontal frame 24 is sleeved on the connecting column 34 through the rotating disk 28, the position of the horizontal frame 24 will not be affected when the connecting column 34 rotates. The screw 26 is rotated, and the moving block 27 is threadedly matched with the screw 26 to slide along the inside of the moving groove 25. After the side frame 21 is unfolded and perpendicular to the moving block 27, the position of the drawing pen 23 can be adjusted so that the pen tip contacts the surface of the pipe. At the same time, the horizontal frame 24 can keep rotating on the central axis of the pipe to guide the rotation path of the drawing pen 23. In the direction, the connecting frame 43 and the drawing pen 23 are on the same section, so the vertical end of the connecting frame 43 slides and is inserted into the slot 29 of the slider 22. Therefore, when the slider 22 is slid along the side frame 21 and the drawing pen 23 moves, the connecting frame 43 and the sliding frame 42 can slide synchronously along the tape measure 41. When determining the drawing position, the locking bolt 211 is rotated to drive the pressure plate 210 to squeeze the surface of the side frame 21, fix the position of the slider 22, maintain the stability of the drawing pen 23 when it rotates in a circle, and avoid the deviation of the drawing direction. The two drawing positions of a section of pipe are manually recorded to obtain the distance, and the length of the cut pipe is measured by subsequent measuring equipment to detect the error value of the tape measure 41. After the drawing is completed, the device is retracted, and the tape measure 41 is reeled in by the reeling seat 44. The two triangular seats 1 are close to each other, which reduces the volume of the device and is convenient to carry.
