DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1: Figures 1 to 6 As shown, an intelligent concrete pouring system based on BIM+GIS technology according to an embodiment of the present invention includes a concrete pump truck 4 and a control server 5;

[0033] The concrete pump truck 4 comprises a vehicle body and a discharge pipe 1;

[0034] The control server 5 includes a pouring schedule generation module 9, a vehicle identification module 6, a vehicle positioning module 7 and a discharge port positioning module 8;

[0035] The pouring schedule generating module 9 is used to automatically generate a pouring schedule for the day according to the schedule, and schedule vehicles according to the pouring schedule;

[0036] The vehicle identification module 6 identifies the vehicle entering the construction site according to the license plate number and feeds back the identification information to the vehicle positioning module 7;

[0037] The vehicle positioning module 7 sends the preset parking point and pouring path to the corresponding vehicle according to the feedback information of the vehicle identification module 6, and automatically navigates the vehicle to the designated location;

[0038] The outlet positioning module 8 is used to locate the coordinates of the outlet in real time during the pouring process;

[0039] During operation, the concrete pouring schedule of the day is generated according to the progress schedule by the pouring schedule generation module 9, which includes information such as concrete model, weight, pouring location, pouring time, etc. The production and transportation of the concrete pump truck 4 is scheduled according to the concrete pouring schedule. When the concrete transport truck departs, the supplier sends the vehicle information and concrete pouring information to the control server 5. When the concrete pump truck 4 arrives at the construction site, the vehicle identification module 6 identifies the vehicle license plate number to obtain the corresponding concrete information, and feeds back the information to the vehicle positioning module 7. The vehicle positioning module 7 sends the preset parking point and pouring path to the corresponding vehicle according to the feedback information of the vehicle identification module 6, and automatically navigates the vehicle to the designated location. When the concrete pump truck 4 arrives at the preset parking point, the discharge port is aligned with the concrete pouring operation surface, and pouring is automatically performed. The discharge port positioning module 8 feeds back the coordinates of the discharge port to the server in real time during the pouring process. The above method simplifies the operation steps, improves the construction efficiency, realizes the automatic pouring of concrete, and only a small number of steps are manually involved, saving manpower and time; and improves the flexibility and safety of the construction process. The whole process of concrete pump truck 4 from positioning to pouring is automated, reducing errors caused by human factors.

[0040] The discharge port positioning module 8 includes a camera, an ultrasonic sensor, a display screen and an alarm. The camera and the ultrasonic sensor are both installed on the discharge pipe 1 of the concrete pump truck 4, and the display screen and the alarm are installed in the cab of the concrete pump truck 4. When working, the camera captures the surrounding conditions of the discharge port and displays it on the display screen, so that the driver can observe the surrounding conditions of the discharge port in real time to avoid collisions. In addition, by setting up an ultrasonic sensor, the distance between the surrounding objects and the sensor can be measured by emitting ultrasonic waves, thereby further preventing collisions.

[0041] The control server 5 further includes a collision detection module, which monitors in real time whether the concrete pouring path is consistent with the preset pouring path according to the coordinate information to prevent collision, so as to monitor the moving path of the concrete pump truck 4 in real time.

[0042] The vehicle positioning module 7 associates the concrete pouring information of a specific part in the BIM model with the preset parking spots and pouring paths through the shift information of the concrete pump truck 4; when working, various information is processed through the BIM model, and the concrete information of the whole process from concrete transportation to pouring is associated with the BIM model, which is easy for construction management and control.

[0043] The vehicle positioning module 7 automatically navigates the concrete pump truck 4 to a preset parking spot through the GIS positioning system; when working, the concrete pump truck 4 is automatically navigated to a designated location without manual guidance, thereby reducing manual work intensity and improving work efficiency.

[0044] The opening of the discharge pipe 1 is also provided with a sealing plate 2 for preventing concrete leakage. The sealing plate 2 is a pair of semicircular plates. A support assembly 3 is provided on the outside of the opening of the discharge pipe 1. The opening or closing of the pair of sealing plates 2 is controlled by the support assembly 3. The support assembly 3 includes a mounting frame fixedly installed on the outside of the opening of the discharge pipe 1. The mounting frame is composed of a collar 1 31, a fixing rod 32 and a collar 2 33. The fixing rod 32 is provided with multiple groups and symmetrically fixedly connected between the collar 1 31 and the collar 2 33 arranged in parallel above and below. The opposite sides of the two sealing plates 2 are fixedly connected with connecting rods 34 respectively. The connecting rods 34 are fixedly connected to the opposite sides of the two sealing plates 2. A rotating block 35 is fixed to the middle of the connecting rod 34, a rotating seat 36 is fixed to the side wall of the collar 1 31, the rotating block 35 is rotatably installed in the middle of the rotating seat 36, a cylinder 39 is fixed to the side wall of the collar 2 33, a vertical rod 38 is slidably installed in the middle of the cylinder 39, an oblique support rod 37 is rotatably installed at the end of the connecting rod 34 away from the sealing plate 2, the top of the oblique support rod 37 is rotatably connected to the bottom of the vertical rod 38, a movable block 311 is fixed to the vertical rod 38, the movable block 311 is slidably arranged inside the cylinder 39, and a spring 1 310 is installed inside the cylinder 39 to reset the movable block 311;

[0045] During operation, during the automatic pouring process, the discharge pipe 1 is aligned with the pouring position. At this time, the concrete pushes the sealing plates 2 on both sides from the inside. The sealing plates 2 rotate around the rotating block 35 and push the diagonal support rods 37 and the vertical rods 38 upward through the connecting rods 34. The vertical rods 38 drive the movable block 311 to move and squeeze the spring 1 310. At this time, the sealing plates 2 can be opened to both sides to discharge the concrete from the discharge port. When the pouring position needs to be changed, the discharge of concrete is first stopped, and the discharge pipe 1 is moved to a new pouring position, and then pouring is carried out. At this time, the vertical rods 38, the diagonal support rods 37 and the connecting rods 34 can be pushed to move in the opposite direction under the rebound action of the spring 1 310, and finally the sealing plates 2 are re-covered at the outlet of the discharge pipe 1. This can prevent the concrete from flowing out of the outlet during the movement of the discharge pipe 1, polluting the surrounding environment, and even causing safety hazards.

[0046] A through hole is provided on the bottom side wall of the cylinder 39, and a sleeve rod 314 is fixedly installed on the outside of the through hole. A limiting column 313 is slidably installed in the middle of the through hole. A spring 2 315 is installed inside the sleeve rod 314 to reset the limiting column 313. A limiting groove 312 is provided on the side wall of the movable block 311, and the end of the limiting rod is adapted to the limiting groove 312. When working, the discharge pipe 1 is moved to a new pouring position. During the pause of the discharge pipe 1, some concrete may be squeezed out from the middle of the sealing plate 2 due to inertia. At this time, the limiting column 313 is pushed to be clamped in the limiting groove 312 by setting the spring 2 315. The inertial force generated by the momentary pause makes it difficult to squeeze the limiting column 313 out of the limiting groove 312, thereby ensuring that the position of the movable block 311 remains unchanged, so that the sealing plate 2 is always in a closed state to avoid accidental leakage of concrete.

[0047] Embodiment 2: Figure 5 As shown, compared with Example 1, another implementation of the present invention is: the side of the vertical rod 38 is fixedly connected with a cross rod 316, and the cross rod 316 is rotatably installed with a roller 317 away from the end of the vertical rod 38, and the roller 317 abuts against the side of the fixed rod 32; when working, the vertical rod 38 is supported by the cross rod 316 and the roller 317, so that the up and down movement of the vertical rod 38 is more stable, and the vertical rod 38 is prevented from being deformed after long-term use.

[0048] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
