Description

Technical Field

[0001] The utility model relates to the technical field of hollowing hammers, in particular to a multi-angle adjustable hollowing hammer for civil engineering projects. Background Art

[0002] Hollowing is caused by the presence of air in the original masonry and the powder ash layer. When testing, use a hollowing hammer or a hard object to tap the plaster layer and the leveling layer. If a thumping sound is heard, it is a hollowing. In house quality, hollowing generally refers to the hollowing phenomenon between the floor, wall, ceiling decoration layer and the structural layer of the house due to loose bonding and bonding, commonly known as "two layers of skin".

[0003] China's utility model patent application number: 202220898459.8 discloses a multi-angle adjustable civil engineering project detection hollowing hammer, which is provided with a first driving gear, a second driving gear, a first rotating plate, a second rotating plate and a driving motor. Running the driving motor can drive the first driving gear to rotate, and the first driving gear drives the second driving gear to rotate, thereby driving the hollowing hammer head to rotate through the first rotating plate and the second rotating plate, so that the angle of the hollowing hammer head can be adjusted according to needs, and the adjustment is relatively convenient, making it more convenient to use.

[0004] However, in the above patent, although the angle of the hammer head of the hollowing hammer can be adjusted when it is in use, when the hammer head of the hollowing hammer is damaged after long-term use, it is not convenient to disassemble and replace the hammer head of the hollowing hammer alone. It can only be disassembled and replaced together with the related components for angle adjustment. Since there are no problems with the related components for angle adjustment, directly replacing them will cause a waste of resources. Therefore, it is necessary to design a multi-angle adjustable civil engineering hollowing hammer. Summary of the invention

The connecting plates 6 are provided with two and are symmetrically distributed at the left and right ends of the support frame 4. The insides of the two connecting plates 6 are both rotatably connected to rotating disks 7. The ends of the two rotating disks 7 that are close to each other are fixedly connected to rectangular plug rods 9. The inside of the support frame 4 is rotatably connected to There are two rotating cylinders 8 distributed on the left and right sides, and the circumferential surface of the rotating cylinder 8 at the left end is installed with an angle adjustment component. The two rectangular plug rods 9 extend into the two rotating cylinders 8 respectively and are slidably connected with the two rotating cylinders 8 respectively. A fixing seat 15 is connected between the two rectangular plug rods 9. The left and right end surfaces of the fixing seat 15 are provided with slots 16. The two rectangular plug rods 9 are connected with the fixing seat 15 through the two slots 16 respectively. The upper end of the fixing seat 15 is fixedly connected with a hollow drum hammer head 3, and the angle adjustment component is used to adjust the angle of the hollow drum hammer head 3; the hollow drum hammer head 3 is located in the middle position of the support frame 4. When working, the utility model has the function of being able to disassemble the hollow drum hammer head 3 separately for replacement.

[0024] Further, if Figure 2 As shown, the displacement adjustment assembly includes a first handle 12, a threaded barrel 11 and a threaded rod 5. The support frame 4 is internally rotatably connected with the threaded barrel 11. The circumferential surface of the threaded barrel 11 is fixedly connected with the first handle 12. The threaded barrel 11 is internally threadedly connected with two threaded rods 5. The two threaded rods 5 are respectively fixedly connected with the two connecting plates 6. The two threaded rods 5 both penetrate the support frame 4 and are slidably connected with the support frame 4. The threads on the surfaces of the two threaded rods 5 are in opposite directions. The inside of the threaded barrel 11 is provided with two internal threads in opposite directions, and the two internal threads are respectively matched with the two threaded rods 5. During operation, the first handle 12 is rotated to drive the threaded barrel 11 to rotate. At this time, the two threaded rods 5 can simultaneously drive the two connecting plates 6 to move away from each other, and then drive the two rectangular plug rods 9 to move away from each other. After the two rectangular plug rods 9 are completely away from the slots 16, the hollow drum hammer head 3 can be disassembled for replacement.

[0025] Further, if Figure 2 and Figure 4As shown, the angle adjustment assembly includes a worm 18, a worm wheel 13, a bearing seat 14 and a second handle 17.

[0028] The working principle of this utility model:

[0029] When in use, the staff can pick up the entire equipment by holding the flexible sleeve 2 and go to the construction site of the civil engineering project to carry out inspection work. Specifically, the wall of the building can be knocked with the hollowing hammer head 3 to detect whether there is hollowing between the wall and the structural layer. When the hollowing hammer head 3 is damaged after long-term use and needs to be disassembled and replaced, the first handle 12 is first rotated to drive the threaded cylinder 11 to rotate. At this time, the two threaded rods 5 can simultaneously drive the two connecting plates 6 to move away from each other, and then drive the two rectangular plug rods 9 to move away from each other. Until the two rectangular plug rods 9 are completely away from the slots 16, the hollowing hammer head 3 can be disassembled and replaced.
