[0002] Construction project cost analysis is a complex and meticulous process that involves a comprehensive assessment of the costs involved in the construction of a building project. Construction project cost refers to the total cost of all expenses incurred from planning to completion, acceptance, and commissioning, including materials, labor, equipment, and overhead. Accurate cost analysis is crucial for the smooth progress of a project, cost control, and subsequent management and operations.

[0003] When analyzing construction project cost data, drawings, etc., it is often necessary to compare them with various charts and drawings. However, the charts and drawings are often fixed on the display analysis board. In order to display more data charts, the existing display analysis board adopts an expandable display board, which takes up a large space when in use and is inconvenient to use.

[0004] Therefore, a construction engineering cost analysis device is proposed. Utility Model Content

[0024] like Figures 1 to 4As shown, a construction project cost analysis device includes a base 1, a lifting mechanism 2 is provided on the top surface of the base 1, and a lifting column 3 is provided on the surface of the lifting mechanism 2, a switching rotation mechanism 4 is provided on both side walls of the lifting column 3, and the rotating part of the switching rotation mechanism 4 is provided with a display movable belt 5, and a pulling switching mechanism 6 for driving the switching rotation mechanism 4 to rotate is fixedly installed at the end of the switching rotation mechanism 4. More specifically, when the display movable belt 5 and the surface of the switching rotation mechanism 4 are mounted, the display movable belt 5 is in a taut state, and the lifting mechanism 2 can be used to vertically lift the lifting column 3, thereby enabling the display movable belt 5 to be vertically fixed and adjusted. By fixing the drawings and data charts on the surface of the display movable belt 5, the area for drawing analysis and display can be increased. Compared with the expandable display analysis board in the prior art, it can save the space occupied by the comparison equipment. The display movable belt 5 on both sides of the lifting column 3 can realize comparative analysis operations on drawings or data charts. When switching drawings, the switching rotation mechanism 4 is driven to rotate by pulling the switching mechanism 6, and the display movable belt 5 can be rotated by switching the rotation mechanism 4. The display movable belt 5 can be used to switch the drawings or data charts fixed on the surface of the display movable belt 5, which is convenient for comparative analysis of drawings and data charts.

[0025] At least four sets of self-locking universal wheels 7 are fixedly mounted on the bottom surface of the base 1, and the self-locking universal wheels 7 are arranged in a rectangular array on the bottom surface of the base 1. More specifically, the self-locking universal wheels 7 on the bottom surface of the base 1 facilitate the movement of the device.

[0026] The lifting mechanism 2 includes an H-shaped frame 201, the H-shaped frame 201 being fixedly mounted on the top surface of the base 1. A motor 202 is fixedly mounted on the top surface of the base 1 and located inside the H-shaped frame 201. A threaded rod 203 is fixedly mounted on the output end of the motor 202, extending through the H-shaped frame 201. A guide rod 204 is fixedly mounted on the inner top surface of the H-shaped frame 201. A lifting column 3 is threadedly mounted on the surface of the threaded rod 203, and the surfaces of the lifting column 3 and the guide rod 204 are movably mounted. More specifically, the threaded rod 203 is driven to rotate by the motor 202, and the threaded rod 203 and the lifting column 3 are threadedly mounted, so that the threaded rod 203 moves vertically along the inner wall of the H-shaped frame 201, thereby enabling the vertical height of the display movable belt 5 to be adjusted.

[0027] The switching mechanism 4 includes a rotating shaft 401. The rotating shafts 401 are rotatably mounted on the left and right side walls of the switching mechanism 4. Side plates 402 are rotatably connected to the surface of the rotating shaft 401. A rotating wheel 403 is fixedly mounted on the surface of the rotating shaft 401. The surface of the rotating wheel 403 is also mounted with a pull-to-switch mechanism 6. More specifically, pulling the switching mechanism 6 drives the upper rotating shaft 401 and rotating wheel 403 to rotate. The rotation of the rotating shaft 401 and rotating wheel 403 further rotates the display belt 5, enabling the switching operation between the drawings and data charts displayed on the surface of the display belt 5.

More specifically, by pulling the zipper 603, the engagement between the zipper 603 and the groove 602 on the surface of the switch wheel 601 drives the switch wheel 601 and the rotating shaft 401 to rotate.

[0029] When performing a cost analysis, engineering drawings and data charts are secured to the surface of a flexible display belt 5 using adhesive tape. More specifically, the adhesive tape secures the engineering drawings and data charts to the surface of the display belt 5 so that they can be rotated and switched with the display belt 5.

[0030] In summary: when the display movable belt 5 and the surface of the switching rotation mechanism 4 are mounted, the display movable belt 5 is in a taut state, and the lifting mechanism 2 can be used to vertically lift the lifting column 3, thereby enabling the display movable belt 5 to be vertically fixed and adjusted. By fixing the drawings and data charts on the surface of the display movable belt 5, the area for drawing analysis and display can be increased. Compared with the expandable display analysis board in the prior art, it can save the space occupied by the comparison equipment. The display movable belt 5 on both sides of the lifting column 3 can realize comparative analysis operations on drawings or data charts. When switching drawings, the switching rotation mechanism 4 is driven to rotate by pulling the switching mechanism 6, and the display movable belt 5 can be rotated by switching the rotation mechanism 4. The display movable belt 5 can be used to switch the drawings or data charts fixed on the surface of the display movable belt 5, which is convenient for comparative analysis of drawings and data charts.
