[0002] Project cost refers to the construction price of a project, which is the total amount of all costs expected or actually required to complete the construction of a project. Pipeline laying is a link in the construction of a project. In order to confirm the accuracy of the cost budget in actual construction, it is necessary to measure the length of the pipeline.

[0003] After searching, the Chinese patent publication number CN220018459U discloses a pipeline length measuring device for engineering cost, including a clamping ring plate and a connecting platform. There are two groups of clamping ring plates, and the two groups of clamping ring plates are arranged opposite to each other. The connecting platform is located at the upper ends of the two groups of clamping ring plates, and the two groups of clamping ring plates are connected through the connecting platform. An adjustment support assembly is provided at the outer lower end of the clamping ring plate, and laser rangefinders are provided on both sides of the connecting platform, and a matching measurement assembly is provided to match the laser rangefinder.

[0028] Example 1

[0029] A pipeline length measuring device, such as Figures 1 to 5 As shown, it includes a distance measuring mechanism and a laser emitting mechanism. The distance measuring mechanism includes a base plate 1 supported on the ground and a height adjustment component 3. The height adjustment component 3 is fixed to the outer wall of the top of the base plate 1. A fixed frame 4 is fixed to the top of the height adjustment component 3. A controller 5 is arranged on one side of the fixed frame 4. The controller 5 is electrically connected to the central processing unit inside the fixed frame 4. A slide groove 10 is opened on the outer wall of the top of the fixed frame 4. A movable plate 6 is slidably connected to the inner wall of the slide groove 10. A threaded rod 12 is rotatably connected to the inner wall of the slide groove 10. The threaded rod 12 is threadedly matched with the movable plate 6. One end of the threaded rod 12 is connected to a motor 11. A laser rangefinder 7 is fixed to the top of the movable plate 6. A top positioning component 9 and a side positioning component 8 are fixed to the outer wall of the bottom surface of one end of the movable plate 6. The side positioning component 8 includes a fixed plate 19 and a pressure plate 20. The fixed plate 19 is fixed to the outer wall of the bottom end of the movable plate 6. The pressure plate 20 is slidably matched with the movable plate 6. The top positioning assembly 9 has the same structure as the side positioning assembly 8, but the moving directions of the pressure plate 20 in the top positioning assembly 9 and the pressure plate 20 in the side positioning assembly 8 are staggered. The height adjustment assembly 3 includes a sleeve 13 and a lifting rod 14. The sleeve 13 is fixed to the outer wall of the top end of the bottom plate 1. The lifting rod 14 longitudinally slides in the inner wall of the sleeve 13. The bottom end of the lifting rod 14 is connected to a moving block 16. The inner wall of the bottom end of the sleeve 13 is rotatably connected to a threaded rod 15. The threaded rod 15 is threadedly matched with the moving block 16. The outer wall of the bottom end of the threaded rod 15 is connected to a driven bevel gear 17. One side of the driven bevel gear 17 is meshed with an active bevel gear 18. One side of the active bevel gear 18 is connected to an output shaft of a motor 11 installed on the side wall of the sleeve 13.

[0030] The laser emitting mechanism includes an L-shaped plate 22 and a laser emitter 23 fixed to the outer wall of the top end of the L-shaped plate 22, a side positioning component 8 and a plurality of top positioning components 9 arranged in a straight line are fixed to the inner wall of the bottom end of the L-shaped plate 22, a display screen is arranged on one side of the laser emitter 23, and handles 25 are arranged on both sides of the laser emitter 23.

[0031] When measuring distance, a worker places the distance measuring mechanism on the ground at one end of the pipeline, controls the motor 11 to start through the controller 5, adjusts the position of the laser rangefinder 7, drives the threaded rod 15 to rotate through the transmission of the active bevel gear 18 and the driven bevel gear 17, and moves the moving block 16 to change the height of the laser rangefinder 7. When the pressure plate 20 in the top positioning assembly 9 contacts the top of the pipeline, the pressure detected by the pressure sensor 21 in the top positioning assembly 9 changes, and the height adjustment of the laser rangefinder 7 is completed at this time. At the same time, the threaded rod 12 rotates to drive the moving block 16 to move. The movable plate 6 slides along the slide groove 10 to move the laser rangefinder 7 toward one end of the pipeline, and determines whether the laser rangefinder 7 has moved to one end of the pipeline through the side positioning component 8; at the same time, another staff member holds the laser emitting mechanism and places the L-shaped plate 22 on the other end of the pipeline. The top positioning component 9 and the side positioning component 8 arranged on the inner wall of the L-shaped plate 22 can determine the relative position of the laser emitter 23 and one end of the pipeline. When the positions of the distance measuring mechanism and the laser emitting mechanism are adjusted, the laser emitter 23 emits laser, and the laser rangefinder 7 receives the laser for distance measurement.

[0032] By setting the height adjustment component 3, the side positioning component 8 and the top positioning component 9, the relative positions of the laser distance measuring mechanism and the laser emitting mechanism and the two ends of the pipeline are positioned to avoid the reduction of measurement accuracy due to the position offset of the laser distance measuring mechanism and the laser emitting mechanism.

When the pressure plate 20 in the top positioning component 9 contacts the top of the pipeline, the pressure detected by the pressure sensor 21 in the top positioning component 9 changes, and the height adjustment of the laser rangefinder 7 is completed at this time. At the same time, the threaded rod 12 rotates, driving the moving plate 6 to slide along the slide groove 10, so that the laser rangefinder 7 moves to one end of the pipeline, and determines whether the laser rangefinder 7 moves to one end of the pipeline through the side positioning component 8; At the same time, another staff member holds the laser emitting mechanism and places the L-shaped plate 22 at the other end of the pipeline. The top positioning component 9 and the side positioning component 8 set on the inner wall of the L-shaped plate 22 can determine the relative position of the laser emitter 23 and one end of the pipeline. Then the laser indicator 24 emits an indication laser beam. The staff member can observe whether the positions of the laser rangefinder 7 and the laser emitter 23 are aligned through the cooperation of the laser indicator 24 and the positioning grooves on both sides of the laser rangefinder 7, and adjust the level of the laser rangefinder 7 through the electric support rod 2 when the ground is uneven or the pipeline is tilted as a whole; when the positions of the distance measuring mechanism and the laser emitting mechanism are adjusted, the laser emitter 23 emits laser, and the laser rangefinder 7 receives the laser for distance measurement.
