It is an important branch of civil engineering, covering the entire process from project planning, design, construction to completion and delivery. Construction cost analysis devices are tools used to systematically analyze and manage the costs of construction or civil engineering projects.
[0003] In the current process of construction project cost analysis, especially in group meetings or on-site discussions, paper drawings are still often displayed on display boards so that all parties involved can conduct centralized analysis and cost budgeting. However, when fixing drawings, traditional methods such as paper clips and paperclips are often used for piercing fixation. Although this method can fix the drawings, it requires manually inserting and removing the paper clips, which makes changing drawings cumbersome. This is especially true when frequent changes of drawings are required in cost analysis meetings, which seriously affects the efficiency of cost analysis. Utility Model Content

Detailed Implementation
[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figures 1-6This utility model provides an embodiment of a construction project cost analysis device, comprising: a base 1; a support 3, the support 3 being fixedly connected to the top of the base 1; a mounting block 4, the mounting block 4 being fixedly connected to the top of the support 3; a placement plate 5, the placement plate 5 being disposed on the top of the mounting block 4; a mounting frame 6, the mounting frame 6 being fixedly connected to the top of the placement plate 5; a pull rod 7 and a protrusion 8, the pull rod 7 being disposed inside the mounting frame 6, and the protrusion 8 being fixedly connected to the top of the pull rod 7; a pressure plate 10, the pressure plate 10 being fixedly connected to the bottom of the pull rod 7, and the pressure plate 10 being in contact with the outside of the placement plate 5; and a spring. 11. The bottom of the spring 11 is fixedly connected to the outside of the pressure plate 10, and the top of the spring 11 is fixedly connected to the inside of the mounting bracket 6. The spring 11 is sleeved on the outside of the pull rod 7. An anti-displacement component is also included. The anti-displacement component is used to prevent displacement of the engineering cost analysis device during use. A through hole 9 is provided inside the mounting bracket 6, and the pull rod 7 is slidably connected inside the through hole 9. The through hole 9 facilitates the movement of the pull rod 7. A telescopic rod 12 is fixedly connected to the lower part of the mounting bracket 6, and the top of the telescopic rod 12 is fixedly connected to the lower part of the pressure plate 10. The telescopic rod 12 assists in the movement of the pressure plate 10.
[0037] Specifically, when fixing the cost drawing, firstly, pull the protrusion 8, causing it to move the bottom-connected pull rod 7. During the movement of the pull rod 7, since the bottom is fixedly connected to the pressure plate 10, the pressure plate 10 also moves synchronously. At the same time, the movement of the pull rod 7 will compress the spring 11 sleeved on its outside, causing the spring 11 to undergo elastic deformation under the force, thereby storing a certain amount of elastic energy. Next, when the pressure plate 10 continues to move until it is completely detached from the upper surface of the placement plate 5, the top of the cost drawing to be fixed can be... The edge of the tube is inserted below the pressure plate 10 and above the placement plate 5. Then, the pull on the protrusion 8 is released. The reaction force of the spring 11 causes the pull rod 7 and the pressure plate 10 to automatically reset. As the pressure plate 10 returns to its original position, its downward pressing action will firmly press the cost drawing onto the outer surface of the placement plate 5, thereby achieving stable fixation of the drawing. This fixing method is simple to operate, and in actual use, there is no need to use traditional drawing pins, paper clips, or other piercing fixing tools, which avoids damage to the drawing itself and improves the efficiency of drawing replacement and fixing.
[0038] Reference Figures 2-7The anti-displacement component includes a U-shaped frame 13, which is fixedly connected to the middle of the base 1. An electric push rod 14 is fixedly connected inside the U-shaped frame 13. A movable plate 15 is fixedly connected to the output end of the electric push rod 14. Connecting rods 17 are fixedly connected to both sides of the bottom of the movable plate 15. Anti-slip plates 18 are fixedly connected to the bottom of the two connecting rods 17. The anti-slip plates 18 can increase the friction with the ground and prevent the rollers 2 from shifting. Fixed rods 16 are fixedly connected to both sides of the inside of the U-shaped frame 13. The movable plate 15 is slidably connected to the outside of the two fixed rods 16. The fixed rods 16 facilitate the movement of the movable plate 15. Sliding holes 19 are opened on both sides of the inside of the base 1. The two connecting rods 17 are slidably connected to the inside of the two sliding holes 19. The sliding holes 19 facilitate the movement of the connecting rods 17. Rollers 2 are installed around the lower part of the base 1. The rollers 2 facilitate the movement of the device.
[0039] Specifically, after the cost analysis device is moved to the work site or other predetermined suitable position via the rollers 2 located at the bottom, the electric push rod 14 is activated. After the electric push rod 14 is powered on, since the top of the moving plate 15 is fixedly connected to the electric push rod 14, the moving plate 15 is driven to move downward synchronously during the operation of the electric push rod 14. The lower parts of both sides of the moving plate 15 are provided with connecting rods 17, so as the moving plate 15 moves downward, the connecting rods 17 are also pushed downward synchronously. As the connecting rods 17 move downward, the anti-slip plate 18 fixedly connected to its bottom moves downward synchronously until the bottom of the anti-slip plate 18 is in close contact with the ground. When the anti-slip plate 18 is in complete contact with the ground and generates a certain friction force, the electric push rod 14 can be closed, completing the limiting process. After the anti-slip plate 18 makes contact with the ground, it relies on the frictional resistance provided by its material and surface structure to prevent the cost analysis device from displacing or sliding due to external forces or vibrations during use. Through the design of this structure, the limiting operation of the cost analysis device during use is realized, thereby improving the stability of the device in the working state.
[0040] Reference Figures 2-4 A motor 23 is fixedly connected to the rear side inside the mounting block 4. A worm gear 22 is fixedly connected to the output end of the motor 23. A worm wheel 21 is meshed with the outside of the worm gear 22. A rotating rod 20 is fixedly connected to the middle of the worm wheel 21. The rotating rod 20 is rotatably connected inside the mounting block 4. The top of the rotating rod 20 is fixedly connected to the bottom of the placement plate 5.
[0041] Specifically, when adjusting the display angle, start the motor 23. The motor 23 drives the worm gear 22 fixed at the output end to rotate. The rotation of the worm gear 22 drives the externally meshed worm wheel 21 to rotate. The rotation of the worm wheel 21 drives the internally fixed rotating rod 20 to rotate. The rotation of the rotating rod 20 drives the top fixed placement plate 5 to rotate. The rotation of the placement plate 5 drives the externally fixed cost drawing to rotate.
[0042] Working principle: When fixing the cost drawing, firstly, the pull block 8 moves the bottom-fixed pull rod 7, and the movement of the pull rod 7 moves the bottom-fixed pressure plate 10. At the same time, when the pull rod 7 moves, it compresses the externally sleeved spring 11, causing the spring 11 to deform under the force. Then, when the pressure plate 10 is separated from the outside of the placement plate 5, the top of the cost drawing is placed under the pressure plate 10. Then, when the pull block 8 is released, the pressure plate 10 returns to its original position under the reaction force of the spring 11, fixing the cost drawing to the outside of the placement plate 5. This achieves convenient fixing of the cost drawing. When fixing the drawing, there is no need to use piercing fixing methods such as drawing pins or paper clips, making the operation simple and improving the efficiency of cost analysis.
[0043] After the cost analysis device is moved to a suitable position via the rollers 2, the electric push rod 14 is activated. The electric push rod 14 moves the movable plate 15 fixed at the output end downwards. As the movable plate 15 moves, the connecting rods 17 fixed on both sides at the bottom move downwards simultaneously. At the same time, as the connecting rods 17 move, the anti-slip plate 18 fixed at the bottom moves, so that the anti-slip plate 18 contacts the ground. Then, the electric push rod 14 is turned off. This allows for easy limiting of the device when using the cost analysis device, preventing displacement during use and thus improving the stability of the device.
[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
