Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering monitoring and management, and specifically to a construction engineering quality management platform based on blockchain technology. Background Art

[0002] The construction project quality management platform based on blockchain technology mainly uses blockchain, a cutting-edge technology, to innovate the traditional construction project quality management model, and create a transparent, efficient and reliable quality control ecosystem for the construction industry. By integrating the full process data of the construction project, it solves many pain points in the current project quality management, such as information opacity, difficulty in responsibility traceability, and low collaborative efficiency. Project management faces many difficulties. Construction sites, road construction and other activities will generate a lot of dust or impurities, which will have a serious impact on air quality and public health. It is usually necessary to use monitoring and management information screens to monitor and manage environmental factors or other factors on construction sites. To this end, we propose a construction project quality management platform based on blockchain technology. Summary of the invention

[0003] The purpose of the present invention is to provide a construction project quality management platform based on blockchain technology to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a construction project quality management platform based on blockchain technology, comprising a long pole, a monitoring management information screen is fixedly installed on the arc surface of the long pole, a supporting device is provided on the arc surface of the long pole, and the supporting device comprises a mounting frame, the mounting frame is fixedly connected to the arc surface of the long pole, three short poles are fixedly connected to the inner surface of the mounting frame, the arc surface of the short pole is rotatably connected to a support block, three fixing plates are fixedly connected to the arc surface of the mounting frame, a slot is provided on one side of the support block, a rod is slidably inserted in the fixing plate, and the rod is slidably connected to the inner wall of the slot of the support block.

[0005] The effect achieved by the above components is: by setting up the supporting device, the effect of auxiliary support for the long pole is achieved, which avoids the need for staff to fix the long pole and the equipment on the long pole in the construction project area for monitoring and management. Usually, during the process of fixing the long pole, staff are required to support the long pole, and then other staff can use the installation tools to fix the long pole, which makes the operation steps of the staff when installing the long pole more cumbersome and requires a lot of time, thereby improving the practicability of the device.

[0006] Preferably, one end of the insertion rod is fixedly connected to a pulling block, the arc surface of the short rod is sleeved with two torsion springs, and the two ends of the torsion spring are respectively fixedly connected to the mounting frame and the supporting block.

[0007] The effect achieved by the above components is: before installing the long pole, it is usually necessary to fold up the support block to facilitate the transportation of the long pole and the equipment on the long pole to other areas. The torsion force of the torsion spring can make the support block parallel to the long pole, thereby reducing the occupied space and facilitating transportation.

[0008] Preferably, a plurality of pointed cones are fixedly connected to the lower surface of the support block, and the size of the insertion rod is matched with the size of the support block slot.

[0009] The effect achieved by the above components is: a number of sharp cones are designed on the lower surface of the support block, so that the support block can adapt to different terrains. When placed in a loose soil area, the sharp cones at the lower end of the support block can penetrate into the loose soil, making the support block more stably supported on the loose soil surface, thereby improving the stability of the device.

[0010] Preferably, the arc surface of the long rod is fixedly connected to two fixed blocks, the surface of the fixed block is fixedly connected to a threaded rod, the arc surface of the threaded rod is threadedly connected to a mounting plate, a circular ring block is slidably inserted into the arc surface of the long rod, the circular ring block is fixedly connected to one side of the two mounting plates, a circular hole is opened on the surface of the circular ring block, and the threaded rod is slidably connected to the inner wall of the circular hole of the circular ring block.

[0011] The effect achieved by the above components is: before the long pole and the equipment on the long pole are transported to the construction project area, the torsion force of the torsion spring will drive the support block to be parallel to the long pole, and then the sharp cone on the support block will be exposed. The circular ring block can protect the sharp cones on the three support blocks to prevent them from shaking and avoid the sharp cones from being damaged by bumps or injuring the workers.

[0012] Preferably, the arc surface of the insert rod is sleeved with a spring, and two ends of the spring are fixedly connected to the fixing plate and the pulling block respectively.

[0013] The effect achieved by the above components is: when the support block rotates on the arc surface of the short rod and its support block slot is aligned with the insertion rod, the elastic force of the spring will drive the insertion rod to automatically insert into the inner wall of the support block slot, thereby improving the convenience of the device.

[0014] Preferably, a protective device is provided on the surface of the monitoring and management information screen, and the protective device includes a U-shaped groove, and the U-shaped groove is opened on the surface of the monitoring and management information screen. The inner wall of the U-shaped groove is slidably connected to a U-shaped frame, and the inner wall of the U-shaped frame is fixedly connected to a protective plate, and the protective plate is made of acrylic material. The surface of the U-shaped frame is fixedly connected to two connecting plates, and the surface of the monitoring and management information screen is fixedly connected to two arc blocks, and a card slot is opened on the surface of the arc block, and a screw is inserted into the inner thread of the connecting plate, and one end of the screw is rotatably connected to a card block, and the card block is slidably connected to the inner wall of the card slot.

[0015] The effect achieved by the above components is: by setting up a protective device, the effect of protecting the monitoring and management information screen is achieved, and the monitoring and management information screen is avoided from being exposed to the outside world for a long time when it is installed in outdoor places such as construction sites. As a result, during the construction process of the construction site, there may be a lot of gravel or impurities colliding with the surface of the monitoring and management information screen, causing the surface of the monitoring and management information screen to be damaged after the impact, making it impossible for the staff to continue to use the monitoring and management information screen to monitor and manage the construction project area, thereby improving the safety of the device. At the same time, the protective plate is made of acrylic material, and the information on the monitoring and management information screen can be viewed directly through the protective plate.

[0016] Preferably, a limiting rod is slidably inserted in the connecting plate, and one end of the limiting rod is fixedly connected to the clamping block.

[0017] The effect achieved by the above components is: to avoid the situation in which the block rotates continuously with the rotation of the screw rod when the staff rotates the screw rod to drive the block to move toward the inner wall of the slot, making it inconvenient to insert the block into the inner wall of the slot.

[0018] Preferably, a plurality of balls are fixedly connected to the inner wall of the U-shaped frame, and the size of the clamping block is matched with the size of the clamping slot.

[0019] The effect achieved by the above components is that when the staff pushes the U-shaped frame to slide on the inner wall of the U-shaped groove, the setting of the balls can make it slide more smoothly and reduce the friction of the sliding.

[0020] Preferably, an adjustment device is provided on one side of the monitoring and management information screen, and the adjustment device includes a fixed frame, which is fixedly connected to one side of the monitoring and management information screen, a servo motor is fixedly installed on the upper surface of the fixed frame, and a screw rod is fixedly connected to the output end of the servo motor, and a long plate is threadedly connected to the circular arc surface of the screw rod, and a cleaning pad is slidably connected to the inner wall of the long plate.

[0021] The effect achieved by the above components is: by setting the adjustment device, the dust or impurities on the surface of the protective plate can be cleaned. The cleanliness of the protective plate directly affects the staff's observation of the monitor display screen. Keeping the protective plate clean can ensure that the staff can clearly observe the display screen, which is convenient for them to carry out real-time monitoring and management.

[0022] Preferably, a driving rod is inserted into the internal thread of the long plate, and one end of the driving rod is in contact with the cleaning pad.

[0023] The effect achieved by the above components is: the cleaning pad can be replaced regularly. As the cleaning pad is used, its cleaning ability will gradually decrease. Regular replacement of the cleaning pad can ensure that the protective plate can be effectively cleaned frequently and keep the surface of the protective plate clean, thereby ensuring the visibility of the monitoring management information screen.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-5The present invention provides a technical solution: a construction project quality management platform based on blockchain technology, comprising a long pole 1, a monitoring and management information screen 2 is fixedly installed on the arc surface of the long pole 1, and a supporting device 3 is provided on the arc surface of the long pole 1. By setting the supporting device 3, the effect of auxiliary support for the long pole 1 is achieved, avoiding the need for staff to fix the long pole 1 and the equipment on the long pole 1 in the construction project area for monitoring and management. Usually, during the process of fixing and installing the long pole 1, a staff member is required to support the long pole 1, and then other staff members can use the installation tools to fix the long pole 1 conveniently, resulting in the operation steps of the staff when installing the long pole 1 being cumbersome and requiring a lot of time, thereby improving the practicality of the device, and a protective device 4 is provided on the surface of the monitoring and management information screen 2. By setting the protective device 4, the effect of protecting the monitoring and management information screen 2 is achieved, avoiding the monitoring and management information screen 2 being installed in the When working in outdoor places such as construction sites, the monitoring and management information screen 2 is exposed to the outside world for a long time. Therefore, during the construction process, there may be a lot of gravel or impurities that collide with the surface of the monitoring and management information screen 2, causing the surface of the monitoring and management information screen 2 to be damaged after the impact, making it impossible for the staff to continue to use the monitoring and management information screen 2 to monitor and manage the construction project area, thereby improving the safety of the device. At the same time, the protective plate 403 is made of acrylic material, and the information on the monitoring and management information screen 2 can be viewed directly through the protective plate 403. An adjustment device 5 is provided on one side of the monitoring and management information screen 2. By setting the adjustment device 5, the dust or impurities on the surface of the protective plate 403 can be cleaned. The cleanliness of the protective plate 403 directly affects the staff's observation of the monitor display screen. Keeping the protective plate 403 clean can ensure that the staff can clearly observe the display screen, which is convenient for them to conduct real-time monitoring and management.

[0042] The specific arrangement and functions of the supporting device 3, the protective device 4 and the adjusting device 5 are described in detail below.

[0043] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the supporting device 3 includes a mounting frame 301, the mounting frame 301 is fixedly connected to the arc surface of the long rod 1, three short rods 302 are fixedly connected to the inner surface of the mounting frame 301, the arc surface of the short rod 302 is rotatably connected to the supporting block 303, the arc surface of the mounting frame 301 is fixedly connected to three fixing plates 304, a slot is provided on one side of the supporting block 303, a plug rod 305 is slidably inserted in the fixing plate 304, the plug rod 305 is slidably connected to the inner wall of the slot of the supporting block 303, one end of the plug rod 305 is fixedly connected to a pulling block 306, the arc surface of the short rod 302 is sleeved with two torsion springs 307, the two ends of the torsion spring 307 are respectively connected to the mounting frame 301 and the supporting block 30 3 fixed connection, before installing the long pole 1, it is usually necessary to fold up the support block 303 to facilitate the transportation of the long pole 1 and the equipment on the long pole 1 to other areas. The torsion of the torsion spring 307 can make the support block 303 parallel to the long pole 1, thereby reducing the occupied space and facilitating transportation. The lower surface of the support block 303 is fixedly connected with a plurality of sharp cones 308. The size of the plug rod 305 is adapted to the size of the slot of the support block 303. A plurality of sharp cones 308 are designed on the lower surface of the support block 303, so that the support block 303 can adapt to different terrains. When placed in a loose soil area, the sharp cone 308 at the lower end of the support block 303 can be inserted into the loose soil to make the support block 303 The support on the loose soil surface is more stable, which improves the stability of the device. The arc surface of the long rod 1 is fixedly connected to two fixed blocks 309, and the surface of the fixed block 309 is fixedly connected to a threaded rod 310, and the arc surface of the threaded rod 310 is threadedly connected to a mounting plate 311. A circular ring block 312 is slidably inserted on the arc surface of the long rod 1. The circular ring block 312 is fixedly connected to one side of the two mounting plates 311. A circular hole is opened on the surface of the circular ring block 312, and the threaded rod 310 is slidably connected to the inner wall of the circular hole of the circular ring block 312. Before the long rod 1 and the equipment on the long rod 1 are transported to the construction project area, the torsion force of the torsion spring 307 will drive the support block 303 to be parallel to the long rod 1. The circular ring block 312 can protect the sharp cones 308 on the three support blocks 303, so that they will not shake, and avoid the sharp cones 308 from being damaged by bumps or injuring the staff. The arc surface of the insertion rod 305 is covered with a spring 313, and the two ends of the spring 313 are fixedly connected to the fixed plate 304 and the pull block 306 respectively. When the support block 303 rotates on the arc surface of the short rod 302, the slot of the support block 303 is aligned with the insertion rod 305, and the elastic force of the spring 313 drives the insertion rod 305 to automatically insert into the inner wall of the slot of the support block 303, thereby improving the convenience of the device.

[0044] like Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the protective device 4 includes a U-shaped groove 401, which is opened on the surface of the monitoring and management information screen 2, and the inner wall of the U-shaped groove 401 is slidably connected to a U-shaped frame 402, and the inner wall of the U-shaped frame 402 is fixedly connected to a protective plate 403, and the protective plate 403 is made of acrylic material. The surface of the U-shaped frame 402 is fixedly connected to two connecting plates 404, and the surface of the monitoring and management information screen 2 is fixedly connected to two arc blocks 407, and the surface of the arc block 407 is opened with a card slot 408. The connecting plate 404 is internally threaded with a screw 405, and one end of the screw 405 is rotatably connected to a card block 406, and the card block 406 is slidably connected to the inner wall of the card slot 408, and the connecting plate 40 4 is slidably inserted with a limiting rod 409, one end of which is fixedly connected to the block 406, so as to avoid the situation that the block 406 keeps rotating with the rotation of the screw 405 when the staff rotates the screw 405 to drive the block 406 to move toward the inner wall of the slot 408, and it is inconvenient to insert it into the inner wall of the slot 408. The inner wall of the U-shaped frame 402 is fixedly connected with a plurality of balls 410, and the size of the block 406 is adapted to the size of the slot 408. When the staff pushes the U-shaped frame 402 to slide on the inner wall of the U-shaped slot 401, the setting of the balls 410 can make it slide more smoothly and reduce the friction of sliding.

[0045] like Fig.10 and Fig.11 As shown, the adjustment device 5 includes a fixing frame 51, which is fixedly connected to one side of the monitoring and management information screen 2. A servo motor 52 is fixedly installed on the upper surface of the fixing frame 51, and a screw rod 53 is fixedly connected to the output end of the servo motor 52. The arc surface of the screw rod 53 is threadedly connected to a long plate 54, and the inner wall of the long plate 54 is slidably connected to a cleaning pad 55. A driving rod 56 is inserted into the inner thread of the long plate 54, and one end of the driving rod 56 abuts against the cleaning pad 55, so as to achieve the effect of regularly replacing the cleaning pad 55. As the cleaning pad 55 is used, its cleaning ability will gradually decrease. Regularly replacing the cleaning pad 55 can ensure that the protective plate 403 can be effectively cleaned frequently and keep the surface of the protective plate 403 clean, thereby ensuring the visibility of the monitoring and management information screen 2.

[0046] Working principle: When the staff needs to install the long pole 1 and the monitoring management information screen 2 and other equipment on the long pole 1 for monitoring and management at the construction site, the circular ring block 312 is pushed to drive the mounting plate 311 to move on the arc surface of the threaded rod 310 first, until the circular ring block 312 no longer blocks the support block 303, and the support block 303 is pushed to rotate on the arc surface of the short rod 302, and the support block 303 drives the pointed cone 308 to rotate. When it rotates to contact the ground, the slot of the support block 303 is aligned with the insertion rod 305, and the elastic force of the spring 313 drives the insertion rod 305 to automatically insert into the inner wall of the slot of the support block 303. When placed in a loose soil environment, the support block 303 can be pressed to drive the pointed cone 308 to penetrate into the loose soil. By setting the support device 3, the effect of auxiliary support for the long pole 1 is achieved, avoiding the need for staff to fix the long pole 1 and the equipment on the long pole 1 in the construction project area for monitoring and management. Usually, during the process of fixing the long pole 1, a staff member is required to support the long pole 1, and then other staff members can use the installation tools to fix the long pole 1, which makes the operation steps of the staff when installing the long pole 1 more complicated and thus requires a lot of time, thereby improving the practicality of the device.

[0047] When it is necessary to protect the monitoring and management information screen 2, push the U-shaped frame 402 to drive the ball 410 to slide on the inner wall of the U-shaped groove 401, the U-shaped frame 402 drives the protective plate 403 to move, the U-shaped frame 402 drives the connecting plate 404 to move, the connecting plate 404 drives the screw 405 to move, the screw 405 drives the block 406 to move, the block 406 drives the limit rod 409 to move, when sliding to the end of the U-shaped groove 401, the block 406 and the groove 408 are aligned, at this time, the screw 405 can be rotated to drive the block 406 to be stuck into the inner wall of the groove 408, after the installation is completed, the monitoring and management information screen 2 can be protected, by setting the protective device 4. The effect of protecting the monitoring and management information screen 2 is achieved, and the monitoring and management information screen 2 is avoided from being exposed to the outside world for a long time when the monitoring and management information screen 2 is installed in outdoor places such as construction sites. As a result, there may be more gravel or impurities in the construction site during the construction process, which may collide with the surface of the monitoring and management information screen 2, causing the surface of the monitoring and management information screen 2 to be damaged after the impact, making it impossible for the staff to continue to use the monitoring and management information screen 2 to monitor and manage the construction project area, thereby improving the safety of the device. At the same time, the protective plate 403 is set to acrylic material, and the information on the monitoring and management information screen 2 can be directly viewed through the protective plate 403.

[0048] When it is necessary to clean the dust or impurities on the surface of the protective plate 403, start the servo motor 52, and the output end of the servo motor 52 drives the screw rod 53 to rotate, and the screw rod 53 drives the long plate 54 to move up and down on the arc surface of the screw rod 53, and the long plate 54 drives the driving rod 56 and the cleaning pad 55 to move up and down, and the cleaning pad 55 starts to clean the dust or impurities on the surface of the protective plate 403. After cleaning, the long plate 54 is moved to the bottom of the protective plate 403. By setting the adjustment device 5, the dust or impurities on the surface of the protective plate 403 are cleaned. Whether the protective plate 403 is clean or not directly affects the staff's observation of the monitor display screen. Keeping the protective plate 403 clean can ensure that the staff can clearly observe the display screen, which is convenient for them to conduct real-time monitoring and management.
