Embodiment Construction

[0010] The features of the present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can understand.

[0011] Such as figure 1 As shown, the internal combustion engine 14 is installed above the equipment, connected with the shock absorber 16 through the pressure plate 13, the shock absorber 16 is an elastic body, the lower pressure plate 18 is connected with the shock absorber 16, and the lower pressure plate 18 is fixed with the shell 6 of the impact mechanism , The lower cam impact block 25 is installed on the lower bottom plate of the housing 6 . The vibrating shaft overcoat 2 slides in the impact mechanism shell 6, and the sliding position is limited by two limit screws 26. The internal combustion engine 14 starts, drives the clutch disc 15 to rotate at high speed, and the power is transmitted to the drive shaft 8 through the flexible shaft 17. The drive shaft 8 is a gear shaft, and the lowe...

Abstract

The invention provides a hand-held vibration impact internal combustion tamping pickaxe comprising an internal combustion engine, shock absorbers, an impact mechanism and a shock mechanism. The hand-held shock impact internal combustion tamping pickaxe is characterized in that the internal combustion engine is connected with the shock absorbers through pressure plates, the lower ends of the shock absorbers are connected with a box body of the impact mechanism, and the impact mechanism is arranged in the box body; the impact mechanism comprises energy storage springs, driving shafts, an upper cam impact block, a lower cam impact block, planet gears, a gear ring and the like, a sun gear is designed and machined on the driving shafts, and the shock mechanism is connected with the impact mechanism in a matched mode through connecting sleeves; and the shock mechanism comprises shock shafts, outer sleeves and a shock head, the shock shafts are eccentric shafts, and high-frequency shock can be achieved at a high speed. Shock and impact dual functions of the tamping pickaxe are achieved by means of the method that spring energy is utilized by the upper cam impact block of a deceleration strip of a planetary mechanism to continuously impact the shock shaft outer sleeves.

Description

technical field [0001] The invention relates to railway ballast tamping equipment, in particular to a hand-held vibrating impact internal combustion tamping pick which integrates vibration tamping and impact tamping. Background technique [0002] At present, the tamping picks used in the railway construction system include flexible shaft vibration tamping picks, domestic "Little Bee" vibration picks, German "Wick" impact tamping picks, Swedish "Cobra" impact tamping picks and other domestic impact tamping picks. These tamping picks have the following disadvantages: the soft-shaft vibration tamping picks and the domestic "little bee" vibration tamping picks are eccentric shock type and have no axial impact force. Although they do not cause damage to the ballast, the ballast can only Under the action of the shock force, it flows freely with the gravity to achieve compactness, and the sleeper cannot be raised. It is difficult to achieve the result of tamping and compacting with...
