Description

Technical Field

[0001] The present invention relates to the field of engineering project management, and more specifically to a BIM-based construction engineering project management device and a system thereof. Background Art

[0002] An engineering project is a project that uses engineering construction as a carrier. It is a one-time engineering construction task that is managed. It takes buildings or structures as target outputs, and needs to pay a certain fee, follow a certain procedure, and be completed within a certain period of time, and it should meet quality requirements. BIM technology is a digital tool used in engineering design and construction management. It integrates relevant information of various projects through parameter models, and uses this digital information model as the basis for various construction projects to do various related work. In the actual application process, BIM not only includes the information model of the building, but also includes the model of construction engineering management behavior. It perfectly combines the information model of the building with the management behavior model of the construction project. Therefore, within a certain range, the building information model can simulate the actual construction engineering behavior, which has profound significance in engineering cost management.

[0003] In the current engineering project management based on BIM technology, project information is usually displayed and analyzed by connecting the PLC controller to the display, which can better display text and pictures. However, some existing engineering project management information analysis devices cannot adjust the display to rise and fall, so the display cannot be stored and protected, resulting in the operating display used for BIM technology being exposed to the outside for a long time, which is easy to cause damage. Damage will lead to an increase in production costs, which is not conducive to the management of engineering construction projects. The display is not easy to disassemble and install. Therefore, when the display fails, it cannot be quickly disassembled and replaced, which is not conducive to maintenance, resulting in the need to replace the entire device, thereby increasing the cost of use. In addition, the heat dissipation effect of the display is poor, and dust pollution is easily caused during the heat dissipation process, resulting in dust entering the inside of the display and reducing the service life. For this reason, we propose a BIM-based construction project management device and system. Summary of the invention

In addition, by providing a motor box, a heat dissipation hole, a baffle, a piston plate, a spring one, a shaft rod, a rotating cam, a gear ring and a rack, when the driving motor is started and the lifting plate is controlled to rise or fall, the rack will push the gear ring to rotate, thereby driving the rotating cam to rotate, and pushing the piston plate to move back and forth left and right, so that air can be repeatedly extracted and exhausted through the heat dissipation hole, and the driving motor is ventilated and cooled, which has a cooling effect, and ensures that the use temperature can be reduced when the driving motor is started and used.

[0017] The present invention provides an air pressure box, a filter plate, a filter hole, a movable groove, a movable block, a spring, a blocking plate, a cleaning column, an inclined abutment plate, a guide plate, an elastic air bag one, a vent pipe one, a piston plate, a pushing column, a spring three, an elastic air bag two and a vent pipe two, so that when the management display controller is stored in the storage box, the bottom end of the rack will squeeze the elastic air bag two, so that the gas inside the elastic air bag two is filled into the air pressure box. At this time, the pushing column will move upward and cooperate with the inclined abutment plate to push the blocking plate to move right. At this time, the cleaning column will penetrate into the filter hole to guide out the debris inside the filter hole. At the same time, the interior of the elastic air bag one is filled with gas, so that the guide plate becomes inclined, which is convenient for guiding the debris at the cleaning location to flow out of the air inlet. When the management display controller is extended from the storage box, the elastic air bag two expands to extract the gas inside the air pressure box. At this time, the blocking plate will be away from the filter plate, and the filter hole is in a ventilated state. At this time, the cooling fan is started and the air inlet is in an air intake state.

At this time, the connecting groove will connect the elastic telescopic rod with the inside of the cavity. When the elastic telescopic rod is extended or retracted, gas can be drawn in or discharged from the outside, so that the upper card seat can be pulled upward to be turned over, so that the management display controller can be easily drawn out and replaced. When the management display controller is extended from the inside of the storage box, the extrusion block is away from the partition and is pushed by spring four, which will drive the movable piece to slide down. The coordinated linkage head, linkage column, cam groove and linkage rod will pull the sealing baffle to rotate. At this time, the docking hole one and the docking hole two will be misaligned. At this time, the elastic telescopic rod cannot exhaust or draw air to the outside, so that the elastic telescopic rod cannot be freely extended and retracted, thereby ensuring that when the management display controller is outside the storage box, it will be tightly engaged with the upper and lower card seats and is not easy to fall out, thereby avoiding the problem of the management display controller easily falling off during use.
