Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a building engineering cost statistics board. Background Technology

[0002] In the early stages of the construction industry, when information technology applications were not yet widespread, and with project cost data scattered across various paper documents and individual costs requiring manual calculation and summarization, traditional construction cost statistics boards emerged as a basic tool. Their purpose was to centrally present cost information for each stage of the project through a physical carrier, providing the on-site team with intuitive data analysis and collaborative reference, in order to adapt to the cost management model that was mainly manual at the time.

[0003] Traditional construction cost statistics boards rely on a structured, partitioned design on a physical statistical board. They delineate dedicated recording areas for project cost elements according to professional categories (such as civil engineering and installation) and cost composition (labor, materials, and machinery). Basic data for each item is entered manually using handwritten notes or magnetic stickers. Then, direct costs, indirect costs, and other hierarchical summaries are completed through manual calculation. Finally, cost information is presented in an intuitive physical form, achieving centralized display and static association, providing a visualized data reference benchmark for on-site cost management.

[0004] Traditional construction cost statistics boards have a fixed size. As statistical data accumulates and fills the entire board, there's no space left to record new data, forcing staff to erase portions, slowing down the work process. Furthermore, the boards are unstable, easily wobbling under external forces and potentially tipping over, endangering nearby personnel. Therefore, a new construction cost statistics board is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a construction project cost statistics board, which aims to improve the problems of traditional construction project cost statistics boards, such as fixed size leading to insufficient space for recording data when data increases, the need to erase some data reducing work efficiency, poor stability, easy shaking and tipping under external force, and affecting the safety of staff.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a construction project cost statistics board, comprising a sleeve plate, a motor fixedly installed on one side of the top of the sleeve plate, two display plates slidably connected to the inner wall of the sleeve plate, a rack fixedly connected to the top of the display plates, a pulley two fixedly connected to the output end of the motor passing through the inner wall of the sleeve plate, a gear two fixedly connected to the bottom end of the pulley two, a pulley one rotatably connected to one side of the top of the inner wall of the sleeve plate via a bearing, a gear one fixedly connected to the bottom of the pulley one, a synchronous belt sleeved between the pulley one and the pulley two, the gear one and the gear two meshing with the two racks, connecting columns fixedly connected to both ends of the bottom of the sleeve plate, a base plate fixedly connected to the bottom ends of the two connecting columns, threaded rods rotatably connected to the tops of the two connecting columns via bearings, threaded sleeves sleeved on both sides of the surface of the threaded rods, and fixed columns slidably connected to the opposite sides of the two connecting columns.

[0007] As a further description of the above technical solution: both sides of the threaded sleeve are rotatably connected to connecting strips, and both ends of the bottom of the fixed column are fixedly connected to support columns.

[0008] As a further description of the above technical solution: omnidirectional wheels are provided at the four corners of the bottom of the base plate.

[0009] As a further description of the above technical solution: a crank handle is fixedly connected to one end of the threaded rod.

[0010] As a further description of the above technical solution: both the upper and lower ends of the inner wall of the sleeve plate are provided with slide rails, and both the upper and lower ends of the display plate are provided with slide grooves, and the slide rails slide on the inner wall of the slide grooves.

[0011] As a further description of the above technical solution: the bottom end of the connecting strip is rotatably connected to the top of the fixed column.

[0012] As a further description of the above technical solution: the thread directions on both sides of the threaded rod surface are opposite.

[0013] As a further description of the above technical solution: a base block is fixedly connected to the bottom end of the support column.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the motor drives the second gear and the second pulley to rotate, and with the help of the synchronous belt transmission, the first pulley and the first gear rotate synchronously, causing the racks fixed to the two display boards to move. At this time, the two display boards extend outward synchronously, thus achieving the effect of expanding the data recording area.

[0015] 2. In this utility model, the threaded rod is rotated by shaking the handle, which drives the threaded sleeve to move horizontally, causing the connecting strip to drive the fixed column to move vertically, and making the bottom block on the support column touch the ground, thus achieving stable support for the entire equipment, avoiding the equipment from tilting due to external forces or environmental factors, and improving safety.

[0018] 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.

[0019] Reference Figures 1-4This utility model provides an embodiment of a construction project cost statistics board, comprising a sleeve plate 1, a motor 15 fixedly installed on one side of the top of the sleeve plate 1, two display plates 14 slidably connected to the inner wall of the sleeve plate 1, a rack 3 fixedly connected to the top of the display plates 14, a pulley 19 fixedly connected to the output end of the motor 15 through the inner wall of the sleeve plate 1, a gear 20 fixedly connected to the bottom end of the pulley 19, a pulley 16 rotatably connected to one side of the top of the inner wall of the sleeve plate 1 via a bearing, a gear 17 fixedly connected to the bottom of the pulley 16, a synchronous belt 18 sleeved between the pulley 16 and the pulley 19, and gears 17 and 20 meshing with the two racks 3, connecting columns 6 fixedly connected to both ends of the bottom of the sleeve plate 1, a base plate 10 fixedly connected to the bottom of the two connecting columns 6, a threaded rod 13 rotatably connected to the top of the two connecting columns 6 via a bearing, threaded sleeves 9 sleeved on both sides of the surface of the threaded rod 13, and a fixed column 12 slidably connected to the opposite side of the two connecting columns 6. When motor 15 starts, pulley 19 and gear 20 rotate synchronously. Gear 20 meshes with rack 3 on display panel 14 to drive one of the display panels 14 to extend outward smoothly along the preset track. At this time, pulley 19 drives pulley 16 to rotate through synchronous belt 18. Gear 17 at the bottom of pulley 16 also rotates. Gear 17 meshes with rack 3 on the other display panel 14, realizing the synchronous outward extension of the two display panels 14 under the drive of motor 15, increasing the usable area for data recording. By shaking handle 5, threaded rod 13 is rotated, and two threaded sleeves 9 move inward or outward along threaded rod 13 at the same time. Threaded sleeves 9 are connected to fixed column 12 through connecting strip 7. The movement of threaded sleeves 9 will drive the connecting strip 7 to move, thereby pushing fixed column 12 to move upward or downward in the vertical direction, providing support for the entire equipment and preventing the equipment from tipping over due to external force collision during use.

[0020] Reference Figure 1 The threaded sleeve 9 is rotatably connected to both sides by connecting bars 7, and the bottom ends of the fixed column 12 are fixedly connected to support columns 11. When the threaded sleeve 9 moves, the connecting bars 7 rotatably connected on both sides move synchronously, causing the fixed column 12 to move up and down. The support columns 11 at the bottom of the fixed column 12 move with it. The rotatable connection between the threaded sleeve 9 and the connecting bars 7 makes the support system move flexibly.

[0021] Reference Figure 1 The base plate 10 is equipped with casters 8 at the four corners of the bottom, which facilitates the movement of the equipment and allows it to be moved to different locations more flexibly.

[0022] Reference Figure 1 A crank handle 5 is fixedly connected to one end of the threaded rod 13. The operator can control the raising and lowering of the fixed column 12 by manually cranking the crank handle 5 to rotate the threaded rod 13.

[0023] Reference Figures 1-3The upper and lower ends of the inner wall of the sleeve plate 1 are provided with slide rails 4, and the upper and lower ends of the display plate 14 are provided with sliding grooves 2. The slide rails 4 slide on the inner wall of the sliding grooves 2. The guiding function of the slide rails 4 on the sliding grooves 2 ensures that the two display plates 14 remain stable during the movement and avoids deviation or jamming.

[0024] Reference Figure 1 The bottom end of the connecting strip 7 is rotatably connected to the top of the fixed column 12, forming a movable linkage structure, which makes the support adjustment operation flexible and reliable.

[0025] Reference Figure 1 The threads on both sides of the threaded rod 13 have opposite directions. When the crank handle 5 is turned to rotate the threaded rod 13, the threaded sleeves 9 on both sides will move in opposite directions due to the different rotation directions of the threads.

[0026] Reference Figure 1 A base block 21 is fixedly connected to the bottom end of the support column 11. The base block 21 increases the contact area with the ground, thereby improving the stability of the entire equipment.

[0027] Working principle: During operation, the user only needs to start the motor 15, which drives the connected gear 20 to start rotating. Since the gear 20 meshes with the rack 3 on the side of the display plate 14, as the gear 20 rotates, the rack 3 will drive the corresponding display plate 14 to be pushed out smoothly along the slide rail 4. At this time, the pulley 19 on the motor 15 will also rotate synchronously. Under the transmission action of the synchronous belt 18, the pulley 16 is driven to rotate, which in turn causes the gear 17 fixedly connected to the pulley 16 to rotate. The gear 17 also meshes with the rack 3 of the other display plate 14, allowing the two display plates 14 to extend outward synchronously under the drive of the motor 15, effectively expanding the usable area for data recording. The user can crank the handle 5 to start rotating the threaded rod 13. During the rotation of the threaded rod 13, the two threaded sleeves 9 will move inward or outward along the threaded rod 13 at the same time. The threaded sleeves 9 are connected to the fixed column 12 through the connecting strip 7. The movement of the threaded sleeves 9 will drive the connecting strip 7 to rotate, thereby pushing the fixed column 12 to move upward or downward in the vertical direction. When the fixed column 12 moves downward and the bottom block 21 under the support column 11 touches the ground, it can provide solid support for the entire device and prevent shaking due to external collisions or environmental factors during use.

[0028] 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.
