Description

Technical Field

[0001] This utility model relates to the field of building material testing technology, and in particular to a density testing device for building engineering boards. Background Technology

[0002] Construction board is a material used in building structures, commonly used in building walls, roofs, floors, partitions, etc. It is mainly made of wood particles, fine wood chips or other fibrous materials and a suitable amount of adhesive. When testing the density of construction board, corresponding testing devices are generally used.

[0003] The applicant found through a search that a Chinese patent discloses "a density testing device for building engineering boards", with the publication number "CN222189061U". This patent mainly measures the volume of building engineering boards by accurately measuring the volume of water discharged when the building engineering boards are immersed in water. There is no need to remove the building engineering boards, which effectively avoids the adverse interference of water droplets attached to the building engineering boards after they are removed from the water on the volume measurement. This can improve the accuracy of building engineering board density testing and is relatively simple to use.

[0004] The aforementioned device can improve the density accuracy of building slabs through a series of structural designs. However, in actual use, the device is laid down and raised horizontally, which causes a large amount of water to remain on the top surface of the slabs when they are raised. As a result, workers need to manually clean the water off the surface of the slabs before removing them, which increases the workload of the workers and makes the device less effective. Utility Model Content

One end of the water delivery pipe 7 is fixedly connected to one side of the inner tub 4. A water suction pipe 8 is fixedly connected to the input end of the water pump 6. One end of the water suction pipe 8 is fixedly connected to one side of the surface of the outer tub 1. A lifting component 3 is provided on one side of the surface of the outer tub 1, which can drive the fixing frame 9 and the panels on the fixing frame 9 to lift and lower to complete the density testing. A cleaning component 2 is provided on the fixing frame 9, which can reciprocate as the fixing frame 9 rises to clean the residual water on the panels.

[0022] The technical effect achieved by the above embodiment is as follows: after the board is fixed on the fixed frame 9, the lifting component 3 is used to immerse the board in the water of the inner tank 4 to test the density. Then, the lifting component 3 lifts the fixed frame 9 and the board on the fixed frame 9. At the same time as lifting the fixed frame 9 and the board on the fixed frame 9, the cleaning component 2 can be activated, so that the cleaning component 2 can scrape off the water remaining on the board after it is lifted, so as to avoid too much water remaining on the board and affecting the staff to pick up the board, thereby improving the use effect of the device. Example

[0023] like Figure 1 , Figure 2 and Figure 4As shown, a density testing device for building slabs includes all the contents of Embodiment 1. Furthermore, the lifting assembly 3 includes a first column 301, one side of which is fixedly connected to one side of the outer barrel 1. A first mounting groove 307 is formed inside the first column 301. A first motor 302 is fixedly connected to the top surface of the first column 301. The output end of the first motor 302 passes through the top surface of the first column 301 and extends into the interior of the first mounting groove 307. A first lead screw 309 is fixedly connected to the output end of the first motor 302. The bottom end of the first lead screw 309 is rotatably connected to the bottom surface of the first mounting groove 307. The lifting assembly 3 also includes a mounting block 304 and a support rod 306. The inner walls of both the mounting block 304 and the support rod 306 are connected to the first lead screw 309. The inner wall of the lifting assembly 3 is threadedly connected to the second column 305. One side of the second column 305 is fixedly connected to the mounting block 304 and the support rod 306 respectively. The second column 305 has a second mounting groove 308 inside. The top surface of the second column 305 is fixedly connected to the second motor 303. The output end of the second motor 303 passes through the top surface of the second column 305 and extends into the interior of the second mounting groove 308. The output end of the second motor 303 is fixedly connected to the second lead screw 311. The bottom end of the second lead screw 311 is rotatably connected to the bottom surface of the second mounting groove 308. The rod wall of the second lead screw 311 is threadedly connected to the threaded block 310. One side of the threaded block 310 passes through one side of the second mounting groove 308 and is fixedly connected to one side of the fixing frame 9.

[0024] The technical effect achieved by the above embodiment is as follows: when it is necessary to control the lifting and lowering of the fixed frame 9, by starting the first motor 302 and the second motor 303, the first motor 302 and the second motor 303 can drive the first lead screw 309 and the second lead screw 311 to rotate. As the first lead screw 309 rotates, the mounting block 304 and the support rod 306 can move along the rod wall of the first lead screw 309, thereby achieving the effect of controlling the lifting and lowering of the second column 305. Then, when the second lead screw 311 rotates, it can drive the threaded block 310 to move along the rod wall of the second lead screw 311, thereby achieving the effect of driving the fixed frame 9 and the plate on the fixed frame 9 to lift and lower. Example

[0025] like Figure 1 , Figure 3 and Figure 4As shown, a density testing device for building slabs includes all the contents of Embodiment 2. In addition, the cleaning component 2 includes two fixing plates 201, the bottom surfaces of which are fixedly connected to the top surface of the fixing frame 9.

The inner wall of the scraper 204 is slidably connected to the wall of the limiting rod 203.

[0026] The technical effect achieved by the above embodiment is as follows: when the second lead screw 311 drives the threaded block 310 and the fixed frame 9 to move upward, the transmission gear 206 can mesh with the rack 205 as the fixed frame 9 rises, thereby causing the transmission gear 206 to drive the third lead screw 202 to rotate. Under the rotation of the third lead screw 202 and the limitation of the limiting rod 203, the scraper 204 is caused to move along the rod wall of the third lead screw 202, so that the scraper 204 can scrape off the water remaining on the plate. Example
