Description

Technical Field

[0001] The utility model relates to the technical field of on-line monitoring of concrete, in particular to a concrete mixer truck with an on-line monitoring device. Background Art

[0002] Commercial concrete still requires a lot of transportation time from production to pouring. At this stage, the concrete will gradually lose its construction performance as the cement hydration reaction proceeds, which is also called slump loss over time. Therefore, it is usually stipulated that the operation time of concrete mixer trucks shall not exceed 1.5 hours. At present, most mixing stations will also use retarders to reduce the performance loss of commercial concrete during transportation, and place different types of admixtures on the truck. When the vehicle arrives at the construction site, the external inspection personnel stationed at the construction site will adjust the materials on site as needed. However, there are always some unavoidable emergencies in reality, such as traffic jams and queues at construction sites. The method of extending the setting time of ready-mixed concrete by using retarders still cannot ensure that every truck of concrete can be poured smoothly. In addition, there are many factors such as raw material quality, mix ratio, climate temperature, etc. that will also affect the construction performance of ready-mixed concrete, which undoubtedly increases the workload of external inspection personnel. At present, some companies on the market have also developed remote vehicle-mounted monitoring devices. The remote vehicle-mounted monitoring device is equipped with an admixture addition system to enable technicians to monitor the status of the concrete mixture in the concrete mixer truck in real time on the mobile terminal without leaving home, and add admixtures according to actual construction needs.

[0003] In the prior art, since concrete mixture will inevitably spray onto the camera during use, its installation method and structural shape make it difficult to disassemble the internal structure, making subsequent maintenance difficult. Utility Model Content

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figures 1 to 6 The present embodiment provides a concrete mixer truck with an online monitoring device, including a mixer truck 1, a mixing drum 2 is provided on the mixer truck 1, a feed hopper 4 is provided on the mixer truck 1, a shell 3 is provided between the feed hopper 4 and the mixing drum 2, and an adjustment seat 5 is provided in the shell 3, two support plates 6 are fixedly installed on the adjustment seat 5, a chassis 7 is fixedly installed on the adjustment seat 5, a motor 8 is fixedly installed in the chassis 7, an angle rod 9 is rotatably connected between the two support plates 6, two sleeve plates 10 are fixedly connected to the angle rod 9, and an adjustment component and a stabilization component are provided on the adjustment seat 5.

[0022] In this embodiment, an adjustment plate 11 is fixedly connected to the two set plates 10 , and a camera 12 and a fill light 13 are provided on the adjustment plate 11 .

[0023] In this embodiment, a cover plate 14 is installed at the opening of the housing 3 , a fixing block 15 is fixedly connected to the cover plate 14 , an electric push rod 16 is fixedly provided on the fixing block 15 , and one end of the electric push rod 16 is fixedly connected to the adjustment seat 5 .

[0024] In this embodiment, the adjustment assembly includes a screw 17, which is fixedly connected to the output shaft of the motor 8. A first bevel gear 18 is fixedly connected to the screw 17, and a second bevel gear 19 is fixedly connected to the angle rod 9. The second bevel gear 19 meshes with the first bevel gear 18.

[0025] In this embodiment, the stabilizing assembly includes two positioning wheels 20, and the two positioning wheels 20 are fixedly connected to the angle rod 9. Positioning grooves are provided on the two positioning wheels 20. A threaded sleeve 21 is slidably connected to the screw 17, and a movable plate 22 is fixedly connected to the threaded sleeve 21. Two vertical columns 23 are fixedly connected to the movable plate 22. Spring plates 24 are provided in the two vertical columns 23, and protruding rods 25 are fixedly connected to the two spring plates 24. Sealing strips 26 are provided on both sides of the adjusting seat 5. When the two protruding rods 25 are aligned with the two positioning grooves, the elastic force released by the two spring plates 24 is used to drive the two protruding rods 25 into the two positioning grooves to fix the two positioning wheels 20.

[0026] It should be noted that an electric cylinder for driving the movable plate 22 to rise and fall is provided under the movable plate 22. The electric cylinder is used to push the movable plate 22 upward so that the protruding rod 25 on it can be aligned with the positioning groove and inserted into it, thereby achieving the limit fixation of the positioning wheel 20, and further achieving the limit fixation of the camera 12 and the fill light 13.

[0027] Working principle: The remote monitoring device, i.e., the shell 3, is installed on the outside of the feed hopper 4 and in the gap between the mixing drum 2 through external screws, and then the cover plate 14 is installed on the opening of the shell 3 through external screws. The opening of the shell 3 is sealed so that when the concrete mixture enters the mixing drum 2 through the feed hopper 4 during the loading process of the mixer truck 1, the monitoring device is not affected by the splashing of the concrete mixture, and the protection effect is better. When it is necessary to observe the state of the concrete mixture in the mixing drum 2, the electric push rod 16 drives the adjustment seat 5, the camera 12 and the fill light 13 to move downward, so that the camera 12 is facing the concrete mixture. When observation is not required, the adjustment seat 5, the camera 12 and the fill light 13 are driven upward by the electric push rod 16 to adjust the position of the camera 12 to avoid the situation where the camera 12 is damaged by concrete splashing or backflow when the camera 12 is not in use. When the adjustment seat 5 and the camera 12 retract, the two sealing strips 26 seal the gap between the bottom of the adjustment seat 5 and the shell 3. It is in a closed state, and the camera 12 is in a protected state to prevent cement slurry from entering the shell 3 through the gap and agglomerating, which affects the upward and downward extension of the adjustment seat 5. When the angle of the camera 12 needs to be adjusted, the motor 8 is started, so that the screw 17 drives the second bevel gear 19 to rotate through the first bevel gear 18, and the second bevel gear 19 drives the angle rod 9 to rotate. The angle rod 9 drives the adjustment plate 11 to rotate through the two sleeve plates 10, and the camera 12 and the fill light 13 are adjusted in angle. At the same time, the angle rod 9 drives the two positioning wheels 20 to rotate, and the screw 17 drives the moving plate 22 to move upward through the threaded sleeve 21. The moving plate 22 drives the two vertical columns 23 to move upward, so that the two convex rods 25 are squeezed with the two positioning wheels 20 and compress the two spring plates 24. When the camera 12 and the fill light 13 rotate to a certain angle, the two convex rods 25 are aligned with the two positioning grooves. At the same time, the two spring plates 24 release the elastic force to drive the two convex rods 25 into the two positioning grooves, thereby achieving a limiting and fixing effect on the camera 12.
