[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 This utility model provides a technical solution: an engineering cost and progress management device, including a base 1, a support column 2 fixedly connected to the upper center of the base 1, a first slot 2001 opened inside the upper end of the support column 2, a connecting column 3 provided inside the upper end of the support column 2, a rotating rod 4 fixedly connected to the lower end of the connecting column 3, a rotating ring 5 fixedly connected to the surface of the rotating rod 4, a second slot 2002 opened in the inner center of the support column 2, and a plurality of steel balls 6 provided inside the second slot 2002. By setting the steel balls 6, the contact area between the rotating ring 5 and the inner surface of the support column 2 is reduced, friction is reduced, rotational flexibility is improved, and the service life of the progress management device is improved.
[0026] A frame 7 is fixedly connected to the upper end of the connecting column 3. A threaded groove 9 is opened inside the lower end of the frame 7. An adjustment device 10 is provided inside the threaded groove 9. The adjustment device 10 includes an adjustment motor 101, a threaded rod 102, and a threaded block 103. A pressure rod 12 is provided above the threaded block 103. A connecting rod 11 is fixedly connected to the upper and lower ends of the pressure rod 12. A fixed half ring 13 is provided symmetrically at the center of the surface of the pressure rod 12. By setting up the adjustment motor 101, the threaded rod 102, and the fixed half ring 13, the adjustment motor 101 drives the two threaded rods 102 to rotate, indirectly driving the fixed half ring 13 to move. This allows the two pairs of fixed half rings 13 to move closer and further apart, adjusting the appropriate distance between the two pairs of fixed half rings 13, thereby fixing planning drawings of different lengths. This is practical.
[0027] The surface of the connecting column 3 is rotatably connected to the inner surface of the first slot 2001, the surface of the rotating rod 4 is rotatably connected to the inner surface of the support column 2, the rotating ring 5 is located inside the second slot 2002, the upper and lower surfaces of the rotating ring 5 are rotatably connected to the inside of the second slot 2002, the outer surface of the rotating ring 5 is rolledly connected to the surface of multiple steel balls 6, the two output shafts of the adjusting motor 101 are fixedly connected to the threaded rod 102, the surface of the threaded rod 102 is threadedly connected to the inside of the threaded block 103, the center position inside the threaded groove 9 is installed and connected to the adjusting motor 101, and the surfaces of the two threaded blocks 103 are slidably connected to the inside of the threaded groove 9.
[0028] The frame 7 is internally fixedly connected to a rough plate 8. The lower end of the lower connecting rod 11 is fixedly connected to the upper end of the threaded block 103. The upper end of the frame 7 is provided with a sliding groove 15. A slider 16 is slidably connected at the center of the sliding groove 15. The lower end of the slider 16 is fixedly connected to the upper end of the upper connecting rod 11. The rough surface of the rough plate 8 contacts the back of the planning drawing. Under the pressure of the elastic pressure ring 132, the stability of fixing the planning drawing is improved. The slider 16 slides inside the slider 16, which limits the range of motion of the pressure rod 12 and prevents the fixed half ring 13 from shaking when moving, thus improving the stability of fixing the planning drawing by the fixed half ring 13.
[0029] The fixed half-ring 13 includes a mounting head 131, an elastic pressure ring 132, and an anti-slip pad 133. One side of the mounting head 131 is mounted and connected to the surface of the pressure rod 12, and the other side of the mounting head 131 is fixedly connected to one side of the elastic pressure ring 132. The other side of the elastic pressure ring 132 is fixedly connected to the anti-slip pad 133. The mounting head 131 facilitates the installation and removal of the fixed half-ring 13, and allows for quick replacement of the fixed half-ring 13 when it is damaged, thus improving replacement efficiency. The elastic pressure ring 132 itself has elasticity and flexibility, which can reduce damage to the drawings when fixing planning drawings of different thicknesses, and at the same time facilitates placing the planning drawings between the elastic pressure ring 132 and the rough plate 8.
[0030] The other ends of the two threaded rods 102 are fixedly connected to bearings 14. The outer ring of the bearings 14 is fixedly connected to the inside of the threaded groove 9. Three lights 17 are evenly installed on the upper inside of the frame 7. A drawing tube 18 is installed on the left side of the frame 7, and a double-layer storage box 19 is installed on the right side of the frame 7. The lighting function of the lights 17 is realized at night, so that the staff can clearly see the contents of the planning drawings fixed on the progress management device in the dark night, which improves the efficiency of the staff at night. At the same time, the drawing tube 18 and the double-layer storage box 19 can store planning drawings and tools, prevent dust, moisture and other substances from falling on their surface, and improve their service life.
[0031] Working principle: When in use, the power is turned on. When adjusting the length of the fixed planning drawing of the progress management device, the adjustment device 10 is started. The two output shafts of the adjustment device 10 drive the threaded rod 102 to rotate. The surface of the threaded rod 102 drives the threaded block 103 to move. The upper end of the threaded block 103 drives the connecting rod 11 to move. The upper end of the connecting rod 11 drives the pressure rod 12 to move. The surface of the pressure rod 12 drives the two fixed half rings 13 to move, so that the two pairs of fixed half rings 13 move closer and further apart. The appropriate distance between the two pairs of fixed half rings 13 is adjusted according to the length of the planning drawing, thereby adjusting the length of the fixed planning drawing of the progress management device.
