Description

Technical Field

[0001] The utility model relates to the technical field of rebound hammers, in particular to a rebound hammer for soft rock testing. Background Art

[0002] Soft rock can be divided into two categories: geological soft rock and engineering soft rock. Geological soft rock refers to loose, scattered, soft and weak rock layers with low strength, high porosity, poor cementation, significant influence of structural surface cutting and weathering, or containing a large amount of expansive clay minerals. This type of rock is mostly mudstone, shale, siltstone and mudstone. Engineering soft rock emphasizes the size of the engineering force load borne by the soft rock, and emphasizes the analysis and grasp of the relative essence of the soft rock from the contradictory and unified relationship between the strength of the soft rock and the engineering force load. In the detection of soft rock, a rebound hammer is generally used to test the compressive strength of the wall of the exploration tunnel pre-opened on the soft rock.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] The utility model will now be further described in conjunction with the accompanying drawings.

[0022] Combined with Figure 1-3 A verticality detection component is provided on one side of the rebound tester body 2 on the top surface of the mounting plate 1. The verticality detection component detects the verticality between the detection end of the rebound tester body 2 and the cave wall. The verticality detection component includes a vertical plate 3 and a contact plate 4. The vertical plate 3 is connected to the mounting plate 1. A cross bar 5 is provided on the vertical plate 3. The end of the cross bar 5 away from the vertical plate 3 is hinged with the contact plate 4. A reflector 7 is provided on the surface of the contact plate 4 facing the vertical plate 3. A light transmitter 8 and a light receiver 9 are provided on the vertical plate 3.

[0023] When in use, the contact plate 4 hinged at one end of the cross bar 5 first contacts the cave wall and fits against the cave wall surface, and the angle of the contact plate 4 changes. At this time, the light emitted by the light transmitter 8 is reflected by the reflector 7 on the back of the contact plate 4, and the light receiver 9 cannot receive the light reflected by the reflector 7. At this time, the angle adjustment component adjusts the angle of the rebound tester body 2 through the mounting plate 1 until the light receiver 9 can receive the light reflected by the reflector 7. At this time, the detection end of the rebound tester body 2 is perpendicular to the cave wall, and the driving component is activated, so that the detection end of the rebound tester body 2 contacts the cave wall for detection, thereby ensuring the detection accuracy.

[0024] Combined with Figure 1-2 An angle adjustment component is provided on the bottom surface of the mounting plate 1, and the angle adjustment component is used to adjust the angle of the mounting plate 1. The angle adjustment component includes a support plate 10 and a connecting shaft 11. The support plates 10 are symmetrically arranged on the bottom surface of the mounting plate 1. A connecting shaft 11 is provided between the support plates 10. A gear 12 is provided at one end of the connecting shaft 11. A motor 1 is provided on the inner surface of the support plate 10. A gear 2 13 is provided on the output end of the motor 1. The gear 2 13 is meshed with the gear 12.

[0025] When in use, the connecting shaft 11 is rotatably connected to the upper end of the support rod for installation and support. When the angle of the mounting plate 1 is adjusted, the motor 1 rotates, and the connecting shaft 11 is driven to rotate on the support rod through the engagement of the gear 2 13 and the gear 1 12, so that the angle of the rebound tester body 2 is adjusted through the support plate 10 and the mounting plate 1 until the light receiver 9 can receive the light reflected by the reflector 7.

[0026] Combined with Figure 1-2 The driving assembly drives the rebound tester body 2 to make horizontal movement on the mounting plate 1. The driving assembly includes a second vertical plate 14 and a second motor 15. The top surface of the mounting plate 1 is provided with a second vertical plate 14. A transmission rod 16 is slidably connected to the second vertical plate 14. The transmission rod 16 is connected to the rebound tester body 2. A transmission plate 17 is provided on the end of the transmission rod 16 away from the rebound tester body 2. A spring 18 is provided between the transmission plate 17 and the second vertical plate 14. The mounting plate 1 is provided with a second motor 15. A cam 19 is provided on the output end of the second motor 15. The cam 19 is in contact with the transmission plate 17.

[0027] After the angle adjustment of the mounting plate 1 is completed, the motor 2 15 rotates, driving the cam 19 to rotate, the cam 19 drives the transmission plate 17 to move, the transmission plate 17 squeezes the spring 18, and the transmission plate 17 drives the rebound tester body 2 to move on the mounting plate 1 through the transmission rod 16, so that the detection end of the rebound tester body 2 contacts the cave wall and detects it.
