Description

Technical Field

[0001] This utility model relates to the field of scanning device technology, and in particular to a cost engineering scanning device that is compatible with multiple specifications of drawings. Background Technology

[0002] In the field of construction cost estimation, engineering drawings are crucial documents containing detailed project designs, dimensions, material specifications, and other key information. They play an indispensable role in cost calculation, cost control, and overall project evaluation. As the scale and complexity of engineering projects continue to increase, the specifications of engineering drawings are becoming increasingly diverse, ranging from common A3 and A2 sizes to larger sizes like A1 and A0, and even some custom-designed large-format drawings.

[0003] However, most scanning devices on the market are only suitable for fixing and scanning drawings of a single size. When it is necessary to scan drawings of different sizes, the fixing device needs to be adjusted to fix the drawings, but the adjustment process is very inconvenient. Therefore, a cost engineering scanning device that can adapt to multiple drawing sizes was designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cost engineering scanning device that is compatible with multiple drawing specifications.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cost engineering scanning device adaptable to multi-size drawings includes a worktable. Side plates are fixedly connected to both ends of the top of the worktable. A sliding rod is fixedly connected between the same ends of the two side plates. A movable strip is slidably fitted at the same end of each of the two sliding rods. Circular holes adapted to the sliding rods are formed at both ends of each movable strip. A rectangular groove is formed at the top of each movable strip, and rectangular holes are formed on both sides of each movable strip. A limiting mechanism is provided at both ends of each rectangular groove. The limiting mechanism includes a component fixedly connected to one end of the bottom of the rectangular groove. A fixed plate is provided, and a rod is slidably fitted in the middle of the fixed plate. A circular hole adapted to the rod is provided on the fixed plate. A slider is fixedly connected to the side of the rod near the slide bar, and positioning blocks are fixedly connected to both ends of the slider. Each positioning block is slidably connected in a nearby rectangular hole. An arc-shaped anti-slip pad is fixedly embedded on the side of the slider near the slide bar, and the arc-shaped anti-slip pad is adapted to the slide bar. A limit block is fixedly connected to the other end of the rod, and a second spring is fitted on the rod between the slider and the fixed plate. The setting of the limit mechanism allows the moving bar to be locked on the slide bar.

[0006] Preferably, two positioning rods are slidably sleeved at the center of each rectangular groove, and a round hole adapted to the positioning rod is opened at the center of each of the two moving strips. The bottom of the two positioning rods on the same side is fixedly connected to the same pressure plate, and a rubber pad is fixedly connected to the bottom of each pressure plate. A first spring is sleeved on each positioning rod located between the moving strip and the pressure plate.

[0007] Preferably, the top of the two positioning rods on the same side is fixedly connected to the same top plate, and the top of each top plate is fixedly connected to a handle. By pulling the handle upward, the moving bar can slide on the slide rod, and at the same time the rubber pad is separated from the worktable, which facilitates the fixing of drawings of different sizes.

[0008] Preferably, each of the top plates is rotatably connected to two sides by a connecting rod, and the other end of each connecting rod is rotatably connected to the top of the adjacent slider.

[0009] Preferably, support plates are fixedly connected to both ends of the bottom of the workbench, and guide rods are fixedly connected between the same ends of the two support plates. The same sliding strip is slidably fitted on the circumferential surface of the two guide rods. Both ends of the sliding strip are provided with round holes that are adapted to the guide rods. The same U-shaped frame is fixedly connected to both ends of the sliding strip, and a scanner is fixedly connected to the middle of the bottom of the U-shaped frame.

[0010] Preferably, a lead screw is rotatably connected between the middle of the two support plates, and the lead screw thread passes through the sliding bar. A lead screw nut adapted to the lead screw is fixedly sleeved in the middle of the sliding bar. A servo motor is fixedly connected to the outside of one of the support plates, and the output end of the servo motor passes through the support plate and is fixedly connected to one end of the lead screw.

[0011] Preferably, a processor is fixedly connected to the outer side of one of the support plates, and the processor is electrically connected to the servo motor and the scanner respectively.

[0012] The beneficial effects of this utility model are as follows: By employing technologies such as a moving bar, positioning rod, top plate, slider, rubber pad, connecting rod, second spring, and insertion rod, pulling the handle allows the moving bar to slide horizontally and the rubber pad to rise. Releasing the handle fixes the moving bar to the sliding rod, while the rubber pad descends, enabling quick fixing of drawings of different sizes. This improves efficiency in the early stages of scanning and effectively solves the problem mentioned in the background technology of the inconvenience in scanning drawings of different sizes. It achieves specification adaptability and operational efficiency in the early fixing stage of cost engineering drawing scanning. The flexible adjustment of the mechanical structure adapts to different drawing sizes without requiring equipment changes or frequent device adjustments, significantly shortening drawing clamping time and laying a stable foundation for subsequent high-precision scanning, further promoting the overall efficiency improvement of digital processing of cost engineering drawings.

A slider 9 is fixedly connected to the side of the plug rod 904 near the slide rod 5, and a positioning block 901 is fixedly connected to both ends of the slider 9. Each positioning block 901 is slidably connected in a rectangular hole 602 that is close to each other. An arc-shaped anti-slip pad 902 is fixedly embedded on the side of the slider 9 near the slide rod 5, and the arc-shaped anti-slip pad 902 is adapted to the slide rod 5. A limit block is fixedly connected to the other end of the plug rod 904, and a second spring 905 is sleeved on the plug rod 904 between the slider 9 and the fixing plate 903. Through the setting of the limit mechanism, the moving bar 6 will not slide on the slide rod 5.

[0017] In this utility model, two positioning rods 7 are slidably sleeved in the middle of each rectangular groove 601, and round holes adapted to the positioning rods 7 are opened in the middle of each of the two moving bars 6. The bottom of the two positioning rods 7 on the same side is fixedly connected to the same pressure plate 701. The bottom of each pressure plate 701 is fixedly connected to a rubber pad 702. A first spring 703 is sleeved on each positioning rod 7 between the moving bar 6 and the pressure plate 701. The top of the two positioning rods 7 on the same side is fixedly connected to the same top plate 8. The top of each top plate 8 is fixedly connected to a handle 801. The two sides of each top plate 8 are rotatably connected to connecting rods 802, and the other end of each connecting rod 802 is rotatably connected to the top of the adjacent slider 9. By pulling the handle 801, the limiting mechanism can be unlocked and the rubber pad 702 can be separated from the worktable 1.

[0018] In this utility model, support plates 2 are fixedly connected to both ends of the bottom of the workbench 1. Guide rods 10 are fixedly connected between the same ends of the two support plates 2. The same sliding strip 1102 is slidably sleeved on the circumferential surface of the two guide rods 10. The two ends of the sliding strip 1102 are provided with round holes that are adapted to the guide rods 10. The two ends of the sliding strip 1102 are fixedly connected to the same U-shaped frame 12. A scanner 1201 is fixedly connected to the middle of the bottom of the U-shaped frame 12.

[0019] In this utility model, a lead screw 11 is rotatably connected between the middle of the two support plates 2, and the lead screw 11 is threaded through the sliding bar 1102. A lead screw nut that matches the lead screw 11 is fixedly sleeved in the middle of the sliding bar 1102. A servo motor 1101 is fixedly connected to the outside of one of the support plates 2, and the output end of the servo motor 1101 is fixedly connected to one end of the lead screw 11 through the support plate 2. Under the control of the servo motor 1101, the scanner 1201 can move on the top of the worktable 1 to scan the drawing.

[0020] In this utility model, a processor 4 is fixedly connected to the outer side of one of the support plates 2, and the processor 4 is electrically connected to the servo motor 1101 and the scanner 1201 respectively.

[0021] Working principle: When in use, lay the drawing to be scanned flat on the top of the worktable 1. Move the handle 801 upwards, causing the top plate 8, along with the positioning rod 7 and the pressure plate 701, to rise. This compresses the first spring 703, separating the rubber pad 702 from the top of the support plate 2. Simultaneously, as the top plate 8 rises, the connecting rod 802 pulls the sliders 9 at both ends, compressing the second spring 905. This separates the arc-shaped anti-slip pad 902 from the sliding rod 5, allowing the moving bar 6 to slide freely on the sliding rod 5 until the rubber pad 702 moves to one end of the drawing. Release the handle 801. The rubber pad 702 can press one end of the drawing firmly, while the slider 9 resets, locking the moving bar 6 and the slide bar 5 together. Repeating this operation allows the other rubber pad 702 to press the other end of the drawing firmly, fixing the drawing in place. The processor 4 controls the rotation of the servo motor 1101, causing the scanner 1201 to move on the drawing. This allows the scanned data to be stored in the processor 4 and transferred to a connected computer via data transmission. Pulling the two handles 801 allows the moving bar 6 to move easily, enabling the fixing of drawings of different sizes and improving scanning efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
