[0013] The details and working process of the present invention are described in detail in conjunction with the accompanying drawings of the present invention. The gasoline engine 7 is connected to the rod shell 6-12 of the vibrating rod 6 through the gear box 3, the symmetrically arranged rubber spring 4, the rubber spring clamp 6-2, the I flange 6-3, the connecting sleeve 6-4, and the II flange 6-6; the lower end of the connecting sleeve 6-4 is formed with an outer cone surface 6-4-1, the upper end is formed with a step 6-4-2 for inserting into the I flange 6-3, the II flange 6-6 is formed with an internal thread 6-6-1, and the rod shell 6-12 is formed with an inner cone surface 6-6-1 matching the outer cone surface 6-4-1 of the connecting sleeve 6-4. 12-1 and external thread 6-12-2 matching with internal thread 6-6-1 of flange Ⅱ 6-6, connecting sleeve 6-4 is connected with rod shell 6-12 by conical surface, and flange Ⅰ 6-3 is fastened with flange Ⅱ 6-6 by thread pair; output shaft of gasoline engine 7 is connected with spring flexible shaft 5 through gear box 3, spring flexible shaft 5 is connected with roller cone 6-11 through spring positioning column 6-1 and joint 6-5, handle 1 is fixed at the upper end of rubber spring 4, and throttle combination switch 2 is installed on handle 1. Bearing 6-7, washer 6-8, oil seal 6-9 and oil seal seat 6-10 are installed in rod shell 6-12 of vibrating rod 6, raceway 6-13 is fixed, and the lower end is connected with pick body 6-14 and pick head 6-15 by left thread. When working, turn on the throttle combination switch 2, start the gasoline engine 7, and the power of the gasoline engine 7 is transmitted to the spring flexible shaft 5 through the output shaft of the gear box 3, and then drives the roller cone 6-11 to rotate through the spring positioning column 6-1 and the joint 6-5 in the vibrating rod 6. While the roller cone 6-11 rotates, its outer cone surface rolls along the inner cone surface of the raceway 6-13 fixed in the rod shell 6-12 without sliding (equivalent to the bevel gear with a very small modulus and the inner gear ring meshing and rotating with each other), generating exciting force, which reaches the pick head 6-15 through the rod shell 6-12 and the pick body 6-14, tamping the ballast of the roadbed, overcoming the friction resistance between the ballast, making it move relative and rearrange, filling the gap under the pillow, thereby achieving the purpose of compacting the ballast and stabilizing the roadbed. Since the roller cone 6-11 is required to roll along the inner cone surface of the raceway 6-13 without sliding, there should be no oil stains in the vibrating rod 6. If oil enters, it will cause sliding, causing the vibrating rod 6 to stop vibrating or vibrate weakly, and the vibrating rod 6 must be removed for cleaning. The disassembly method is: loosen the thread pair between the flange Ⅰ 6-3 and the flange Ⅱ 6-6, remove the flange Ⅱ 6-6, the connecting sleeve 6-4 can be disengaged from the rod shell 6-12, unscrew the pick body 6-14 (left thread) together with the pick head 6-15, and then clamp the joint 6-5 to rotate the roller cone 6-11 (right thread), and the roller cone 6-11 will be disengaged from the joint 6-5, and then hold the rod shell 6-12, and gently push the roller cone 6-11 extending out of the rod shell 6-12 vertically onto the wooden board, and all the parts in the vibrating rod 6 except the raceway 6-13 can be removed (the raceway is a non-detachable connection), remove the dust, oil and moisture on the surface of each part, wash it with clean gasoline, and reinstall it after drying. The assembly is carried out in reverse order, and the disassembly and assembly are very convenient, and the on-site maintenance is very convenient.The beneficial effects of the present invention are as follows: the original structural form overcomes the disadvantages of the existing tamping picks such as complex structure, inconvenient disassembly and installation, and difficult on-site maintenance, and meets the urgent needs of simple structure, convenient disassembly and installation, and convenient on-site maintenance required for tamping maintenance of ballasted lines. The innovatively developed rubber spring has good vibration reduction and is comfortable to operate. The machine has strong adaptability, reliable operation, high production efficiency, good tamping effect, novel design, reasonable structure, simple maintenance, and safety and reliability.
