[0026] Furthermore, the clamping mechanism 2 includes a cylinder 201, a first clamping plate 203, a second clamping plate 205 and two guide rails 202.

The output end of the cylinder 201 is fixedly connected to the first clamping plate 203. Both ends of the first clamping plate 203 are fixedly connected to the first rack 204. Both ends of the second clamping plate 205 are fixedly connected to the second rack 206. The two first racks 204 are slidably connected to the second clamping plate 205. Then, the two second racks 206 are both slidably connected to the first clamping plate 203, and gears 207 are rotatably installed on the upper surfaces of the two guide rails 202. The two gears 207 are respectively located between the first racks 204 and the second racks 206 on both sides. The two gears 207 are respectively meshed with the first racks 204 and the second racks 206 on both sides. A limiting groove 208 is provided on the side close to the first clamping plate 203 and the second clamping plate 205. The limiting groove 208 is adapted to the reinforcing ribs at the upper end of the hydraulic hammer body 5, and the reinforcing ribs of the hydraulic hammer body 5 are correspondingly inserted into the limiting groove 208.

[0027] In the present application, by starting the cylinder 201, the first clamping plate 203 is driven to move in the direction close to the hydraulic hammer body 5, the first clamping plate 203 drives the two first racks 204 to move synchronously, the first rack 204 drives the gear 207 to rotate, and the gear 207 drives the second rack 206 to move in the opposite direction, thereby realizing the synchronous movement of the first clamping plate 203 and the second clamping plate 205 until the first clamping plate 203 and the second clamping plate 205 clamp the hydraulic hammer body 5, by setting the meshing connection between the first gear 207, the second gear 207 and the rack, the stability of the first clamping plate 203 and the second clamping plate 205 can be improved, thereby improving the stability of the hydraulic hammer body 5 during the testing process, and by setting the limiting groove 208, the reinforcing ribs of the hydraulic hammer body 5 are inserted into the limiting groove 208, which can prevent the hydraulic hammer body 5 from being displaced between the first clamping plate 203 and the second clamping plate 205, thereby further improving the stability.

[0029] In the specific setting, a number of detection plates 305 are arranged in a circle on the outside of the drill rod of the hydraulic hammer body 5, which are used to detect the accuracy of the impact position of the hydraulic hammer body 5. If the drill rod is offset, it will contact the detection plate 305 when impacting downward, causing the detection plate 305 to rotate around one end of the mounting rod 304, thereby driving the contact piece 307 to move outward. When the contact piece 307 contacts the copper sheet 303, the control terminal receives a signal and records the offset of the corresponding position, which is convenient for subsequent adjustments to the hydraulic hammer body 5.

[0030] The working principle of this utility model:

During operation, the cylinder 201 is started to drive the first clamping plate 203 to move toward the direction close to the hydraulic hammer body 5, and the first clamping plate 203 drives the two first racks 204 to move synchronously. The first rack 204 drives the gear 207 to rotate, and the gear 207 drives the second rack 206 to move in the opposite direction, thereby realizing the synchronous movement of the first clamping plate 203 and the second clamping plate 205, until the first clamping plate 203 and the second clamping plate 205 clamp the hydraulic hammer body 5, and then the hydraulic hammer body 5 is driven by the driving source to make the hydraulic The drill rod of the hammer body 5 reciprocates to strike the force sensor 4, and the impact force generated by the force sensor 4 on the hydraulic hammer body 5 transmits the performance parameters to the control terminal, thereby realizing the detection of the impact performance of the hydraulic hammer. During the hammering process, if the drill rod is offset, it will contact the detection plate 305, causing the detection plate 305 to rotate around one end of the mounting rod 304, thereby driving the contact piece 307 to move outward. When the contact piece 307 contacts the copper sheet 303, the control terminal receives a signal and records the offset of the corresponding position, which is convenient for subsequent adjustments to the hydraulic hammer body 5.
