Both the transmission housing 210 and the clamping plate 203 are provided with clamping portions that can be docked with each other, so that the clamping plate 203 can be sleeved and clamped on the transmission housing 210.

[0044] Preferably, as Figure 2 shown, in the embodiment, the number of both the first shock-absorbing columns 206 and the second shock-absorbing columns 204 is four. The four first shock-absorbing columns 206 and the four second shock-absorbing columns 204 are symmetrically arranged. Such an arrangement can further reduce the vibration impact on the human body from all around.

[0045] Preferably, in the embodiment, both the first shock-absorbing column 206 and the second shock-absorbing column 204 are made of rubber, having good elastic and damping characteristics, and can reduce vibration and noise.

The clutch of the internal combustion engine is connected to the input shaft 209 for power transmission. The input shaft 209 is supported and positioned by bearings 216 and spacer sleeves. The input shaft 209 transmits power to the pick body portion 3 through the intermediate shaft group.

[0050] However, it is not limited thereto. The power transmission method of the input shaft 209 may also be: a gearbox is provided at the lower end of the input shaft 209, and a helical gear shaft is provided inside the gearbox to transmit power. In this way, the power input direction can be changed, the vibration damage to the internal combustion engine itself can be reduced, the failure rate of the internal combustion engine can be lowered, and the service life can be extended.

[0051] Preferably, as Figures 2 to 6 shown, in the embodiment, the transmission portion 2 may further include a transmission housing 210. The transmission component is disposed inside the transmission housing 210, and the transmission housing 210 is connected to the engine mount 208 through a dust cover 211.

The pick head 304 is disposed at the end of the pick body 301. The eccentric block group is sleeved on the main shaft 302. When the main shaft 302 is driven by the intermediate shaft group to rotate at a high speed, it will drive the eccentric block group to perform an eccentric motion inside the pick body 301. The vibration is transmitted to the pick body 301 through the bearings 216 and the bearing seat, and the pick body 301 generates vibration and transmits it to the pick head 304, thereby realizing the vibrating operation.

[0053] Preferably, as Figures 2 to 6 shown, in the embodiment, the intermediate shaft group includes a first intermediate shaft 212, a second intermediate shaft 213, a third intermediate shaft 214, a coupling 215, and a bearing 216. The first intermediate shaft 212 is sleeved on the input shaft 209. The third intermediate shaft 214 is sleeved on the main shaft 302.

[0054] Specifically, mounting holes are provided inside both the first intermediate shaft 212 and the third intermediate shaft 214. The input shaft 209 is mounted in the mounting hole of the first intermediate shaft 212 by means of bolt connection. Both ends of the second intermediate shaft 213 are connected to the first intermediate shaft 212 and the third intermediate shaft 214 respectively through couplings 215. The main shaft 302 is mounted in the mounting hole of the third intermediate shaft 214 by means of bolt connection, which can better transmit power.

[0055] Preferably, as Figures 2 to 6 shown, in the embodiment, the main shaft 302 is rotatably arranged inside the pick body 301 through bearings 216.

[0056] Specifically, both ends of the main shaft 302 are fixedly supported by bearings 216 and bearing seats. A rolling bearing is used at the upper end, and a cylindrical roller bearing is used at the lower end. A bearing bushing is installed between the cylindrical roller bearing and the main shaft 302 for axial positioning to prevent the cylindrical roller bearing from shifting and swinging during high-speed operation. Two sets of eccentric blocks 305 are symmetrically installed at the upper and lower ends of the bearing bushing to ensure uniform and reasonable force on the main shaft 302. In addition, a lock washer and a round nut are installed at the lower end of the main shaft 302 to prevent the two sets of eccentric blocks 305 from moving up and down.

[0057] Preferably, in the embodiment, the pick head 304 is detachably connected to the pick body 301. The shape of the pick head 304 can be a flat head or a pointed head.

The detachable connection method is a threaded connection.

[0058] Preferably, as Figure 2 shown, in the embodiment, the pick body part 3 may further include a connecting pipe 403, a connecting ear 404 and a reinforcing rib 405. Specifically, a connecting ear 404 is provided on the connecting pipe 403, and the connecting ear 404 and the pick body 301 are connected by bolts, which is convenient for disassembly, repair and replacement.

[0059] According to different working conditions, the length of the connecting pipe 403 and the shape of the pick head 304 can be replaced. The connecting pipe 403 and the pick head 304 are connected by a threaded connection, which is convenient for disassembly, replacement and repair. Four reinforcing ribs 405 are annularly arranged at the lower end of the connecting pipe 403 to reduce the wear rate of the connecting pipe 403, increase the vibration range of the ballast, and realize efficient operation.

[0060] The using process of the eccentric tamping pick with shock absorption function is as follows: The internal combustion engine starts, drives the clutch to work and transmits the power to the input shaft 209. The input shaft 209 is connected with the intermediate shaft group and transmits the power to the main shaft 302. Two groups of eccentric blocks 305 are symmetrically installed at both ends of the main shaft 302. The main shaft 302 drives the eccentric blocks 305 to rotate at high speed. The generated eccentric force acts on the pick body 301 through the bearing 216 and the bearing seat and increases its frequency, realizing the radial vibration tamping function and avoiding damaging the ballast and sleepers during operation. The vibration force is transmitted to the pick head 304 to form a stirring force on the ballast. The frictional resistance between the ballasts is overcome and reduced, making the ballast in a nearly flowing state and starting to move relatively and rearrange. After a certain period of time, the void under the sleeper is filled, thus achieving the purpose of compacting the sleeper.

[0061] The eccentric tamping pick with shock absorption function is provided with a three - stage shock absorption component, which can play a role in buffering and shock absorption. On the premise of meeting the operation requirements, it can minimize the vibration damage caused during tamping operation, improve the service life and reliability of the whole machine. At the same time, it can also protect the user, safeguard the physical and mental health of the user, and reduce the labor intensity.
