[0002] BIM, or Building Information Modeling, creates a 4D construction simulation by binding components in the BIM model with tasks in the construction plan. This makes the project handover process more visual and allows the supervision unit to monitor the project progress in a timely manner.

[0003] In existing technologies, staff members use handheld digital mobile devices to walk into the interior of building equipment and compare the 3D building model of BIM on the equipment screen with the actual building structure on site, assisting supervisors in conducting on-site parallel inspections and acceptance of concealed works.

[0004] However, currently, when supervisors compare internal building pipelines, visual errors cause significant discrepancies between what they see and the BIM building model displayed on the monitor, leading to misjudgments and affecting inspection results. To address this, this invention proposes a digital display device for project progress monitoring to solve the aforementioned problems. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1, please refer to Figures 1-9 The present invention provides a technical solution:

[0032] A digital display device for monitoring project progress includes: a mounting frame 1 and a positioning frame 3.

[0033] Specifically, two parallel displays 2 are set on the front of the mounting frame 1, and a camera 11 is installed on the back of the mounting frame 1. The camera 11 is electrically connected to one of the displays 2. One display 2 can display the actual building structure captured by the camera 11 and present it on the display 2 in the form of an image. The other display 2 is used to display the BIM three-dimensional building model structure. Staff and supervisors only need to compare the structure in the images on the two displays 2 to quickly detect whether there are differences between the actual building structure and the BIM three-dimensional building structure model. By comparing the two screens, the detection efficiency can be improved. Combined with the actual structure on site, misjudgment can be avoided. In addition, for areas with differences, further detection and planning of the building structure on site are required.

[0034] Secondly, the positioning frame 3 is installed on the outer back of the mounting frame 1 and can be used to position the mounting frame 1. A support rod 4 is vertically mounted on the surface of the positioning frame 3, and the upper end of the support rod 4 is rotatably connected to the middle position of the upper back of the positioning frame 3. Figure 2As shown, the positioning frame 3 can swing around the support rod 4 at a certain angle under the action of gravity. The staff can hold the lower end of the support rod 4 to move the monitor 2. Even if there is some shaking during the walking, the monitor 2 can still maintain a relatively stable state, thereby ensuring that the direction of the image captured by the camera 11 on the back of the mounting frame 1 will not be significantly different. A stabilizer 5 is set in the middle of the support rod 4. The stabilizer 5 is mainly used to stabilize the connection between the positioning frame 3 and the support rod 4. When the staff walks and shakes, causing the support rod 4 to shake, the positioning frame 3 can rely on gravity to maintain a relatively stable position.

[0035] Furthermore, the stabilizer 5 includes an arc-shaped rod 51, which is perpendicular to and fixedly connected to the support rod 4. When the support rod 4 swings on the back of the positioning frame 3, the arc-shaped rod 51 can move accordingly, and the direction of movement of the arc-shaped rod 51 is to swing around the upper end of the support rod 4. Arc-shaped sleeves 52 are movably sleeved on both outer sides of the arc-shaped rod 51, and the inner cavities of the two arc-shaped sleeves 52 are kept connected through the arc-shaped rod 51. The arc-shaped sleeves 52 are fixedly connected to the positioning frame 3. Therefore, when relative movement occurs between the positioning frame 3 and the support rod 4, the arc-shaped rod 51 will slide in the inner cavity of the arc-shaped sleeve 52. The inner cavity of the arc-shaped sleeve 52 is filled with hydraulic oil, and a return spring 55 is installed at one end. The cooperation of the hydraulic oil and the return spring 55 can produce a damping effect on the relative movement between the arc-shaped rod 51 and the arc-shaped sleeve 52, thereby buffering the shaking and vibration generated when the staff walks, so as to improve the stability of the image captured by the camera 11.

[0036] To reduce the shaking of the positioning frame 3, this application further includes a first piston 53 and a second piston 54 adapted to be movably disposed within the inner cavity of the arc-shaped sleeve 52. The first piston 53 is fixedly connected to the end of the arc-shaped rod 51, and the second piston 54 is fixedly connected to one end of the return spring 55. Hydraulic oil is filled between the first piston 53 and the second piston 54. The return spring 55 and the arc-shaped rod 51 are located at both ends of the arc-shaped sleeve 52, respectively. Figure 4 As shown, when the arc-shaped rod 51 moves between the two arc-shaped sleeves 52, the first piston 53 first uses hydraulic oil as a medium to push the second piston 54 to slide in the inner cavity of the arc-shaped sleeve 52, thereby compressing or stretching the return spring 55. Then, the hydraulic oil flows through the arc-shaped rod 51 from the inner cavity of one arc-shaped sleeve 52 into the inner cavity of the other arc-shaped sleeve 52. Since the hydraulic oil has a large viscosity, it can create a damping effect on the movement of the arc-shaped rod 51. Therefore, when the arc-shaped rod 51 starts to move, it is first buffered by the return spring 55, and then damped by the hydraulic oil, thereby minimizing the shaking of the positioning frame 3 when the support rod 4 shakes.

[0037] To dampen the swing of the arc-shaped rod 51, this application further includes a ventilation opening 521 at the end of the arc-shaped sleeve 52 away from the arc-shaped rod 51. When the second piston 54 slides within the inner cavity of the arc-shaped sleeve 52, outside air can exchange with the air in the inner cavity at the end of the arc-shaped sleeve 52, thereby preventing air pressure from affecting the sliding of the second piston 54. Hollow cavities 56 are provided inside both ends of the arc-shaped rod 51 to store a certain amount of hydraulic oil. The two hollow cavities 56 are connected by a spiral through-hole 561 inside the arc-shaped rod 51. The spiral structure of the spiral through-hole 561 itself can prolong the flow of hydraulic oil within it. The path is designed to fully utilize the viscous effect of the hydraulic oil to enhance the damping effect on the arc-shaped rod 51. A damping hole 531 communicating with the inner cavity of the hollow cavity 56 is provided through the middle of the first piston 53. The diameter of the damping hole 531 and the spiral through hole 561 are the same and both smaller than the diameter of the hollow cavity 56. The hydraulic oil between the first piston 53 and the second piston 54 can pass through the damping hole 531 into the inner cavity of the hollow cavity 56, ensuring that the hydraulic oil in the inner cavities of the two arc-shaped sleeves 52 can be exchanged. The damping hole 531 is a group of small-diameter holes to increase the contact area with the hydraulic oil and fully utilize the viscous effect of the hydraulic oil.

[0038] To securely connect the support rod 4 to the arc-shaped rod 51, this application further includes a fastening slot 511 formed on the middle surface of the arc-shaped rod 51. A connecting sleeve 41 is fixedly connected to the middle of the support rod 4, and the connecting sleeve 41 is sleeved on the outer side of the middle of the arc-shaped rod 51. A fastening screw 42 is threadedly connected through the surface of the connecting sleeve 41, and one end of the fastening screw 42 is inserted into the inner cavity of the fastening slot 511. Figure 5 As shown, the support rod 4 can be fixedly connected to the arc rod 51 by the fastening screw 42. In addition, multiple fastening slots 511 are opened in the length direction of the surface of the arc rod 51, so that the connection position between the support rod 4 and the arc rod 51 can be selected and changed according to the actual use.

[0039] To connect the positioning frame 3 to the support rod 4, this application further includes a connecting shaft 31 fixedly connected to the upper surface of the positioning frame 3, and a connecting collar 44 fixedly connected to the upper end of the support rod 4. The connecting collar 44 is rotatably sleeved on the outside of the connecting shaft 31. The connection between the connecting shaft 31 and the connecting collar 44 ensures that the support rod 4 and the positioning frame 3 can rotate relative to each other. However, since the positioning frame 3 has a certain weight, it can maintain a suspended state at the upper end of the support rod 4 by gravity. Even if the support rod 4 shakes, the positioning frame 3 can maintain a relatively stable position. A handle 43 is fixedly installed at the lower end of the support rod 4 for workers to hold. A mounting base 32 is fixedly connected to the surface of the positioning frame 3, and the mounting base 32 is fixed to the arc-shaped sleeve 52 for installation and positioning of the arc-shaped sleeve 52.

[0040] To facilitate the viewing of the display 2 by the surrounding supervisors, the installation frame 1 of the present application is set in a "曰" - shaped structure for installing two displays 2 respectively. As Figure 6 and Figure 1 shown, the two displays 2 can be kept parallel to each other in the up - down position, so as to facilitate the supervisors to compare and detect the building structures in the pictures of the two displays 2. One end of the display 2 is fixedly connected with a rotating shaft 21, and the display 2 is rotationally connected to the installation frame 1 through the rotating shaft 21. The display 2 can rotate at a certain angle as Figure 1 shown. Without changing the shooting angle of the camera 11, the display 2 can be rotated to face the side, which is convenient for other surrounding supervisors to view. A synchronous connecting rod 22 is fixedly connected between the other ends of the two displays 2. An avoidance slot 14 corresponding to the synchronous connecting rod 22 is opened on the surface of the installation frame 1. The synchronous connecting rod 22 is provided to connect the two displays 2 together to ensure that the two displays 2 keep the same orientation.

[0041] To limit the rotation angle of the display 2, the present application also has a receiving groove 12 horizontally opened in the middle of the surface of the installation frame 1 and communicating with the avoidance slot 14. Limiting chutes 13 are opened on the upper and lower inner walls of the receiving groove 12. A limiting connecting rod 6 is rotatably sleeved outside the synchronous connecting rod 22. One end of the limiting connecting rod 6 extends into the receiving groove 12 and is fixedly connected with a sliding pin 61 through it. The upper and lower ends of the sliding pin 61 are respectively slidably inserted into the two limiting chutes 13. The cooperation between the sliding pin 61 and the limiting chutes 13 ensures that the end of the limiting connecting rod 6 can only slide in the inner cavity of the receiving groove 12 and will not be separated from it. As Figure 1 and Figure 7 shown, the limiting connecting rod 6 can connect the installation frame 1 and the display 2, and the limiting connecting rod 6 is used to limit the rotation angle of the display 2.

[0042] To store and rotate the display 2, the present application also has a baffle 15 fixedly connected to the horizontal inner wall of the installation frame 1, and the baffle 15 abuts against the back of the display 2 to ensure that the display 2 can keep a stable position after being retracted into the installation frame 1. An X - shaped frame 16 is fixedly connected between two adjacent upper and lower baffles 15 to reinforce the strength of the installation frame 1 itself. A notch groove 17 corresponding to the two displays 2 is opened on the side of the installation frame 1, which is convenient for the staff to rotate the display 2 by pulling it from the side of the display 2. A rubber pad 23 corresponding to the notch groove 17 is adhered to the side of the display 2 to increase the friction between the staff's fingers and the side of the display 2.

[0043] To connect the positioning frame 3 to the mounting frame 1, this application further includes symmetrically provided positioning slots 18 on both the upper and lower surfaces of the mounting frame 1. Claws 33 are fixedly connected to both the upper and lower sides of the positioning frame 3, and the claws 33 engage with the slots of the positioning slots 18 to connect and fix the positioning frame 3 to the display 2. Figure 6 and Figure 3 As shown, the front end of the claw 33 is a wedge-shaped structure. The mounting frame 1 can squeeze the front end of the claw 33 to cause a slight deformation, which facilitates the positioning frame 3 to clamp and connect the mounting frame 1. In addition, the mounting frame 1 and the display 2 can be removed from the positioning frame 3. A recess is provided on the upper part of the positioning frame 3 for the camera 11 to pass through, in order to avoid collision between the camera 11 and the positioning frame 3.
