Variable stroke separation type high-speed hydraulic tamping machine

Abstract

The invention discloses a variable-stroke separate high-speed hydraulic rammer compactor, which comprises a compacting frame, a compacting foot, a compacting hammer, a hydraulic cylinder, a hydraulic control circuit and an electric control circuit, wherein the top of the compacting hammer is provided with a cavity; a set of cam type locking and releasing mechanism is arranged in the cavity; the cam type locking and releasing mechanism comprises a pair of eccentric cams, two torsional springs and two camshaft shifting forks; the bottom of a hydraulic cylinder piston rod is provided with a connector; the outer rotary surfaces of the cams are provided with a circle of circular-arc grooves, so that a channel is formed between the cams; the channel is aligned with the vertical direction of theconnector; the compacting frame is provided with two shifting fork carrier rods along the vertical direction; and the two fork shifting carrier rods are aligned with the triggering ends of the two camshaft shifting forks in the vertical direction. A hydraulic driving system in the invention is easy to control, the hydraulic system and the entire structure of the rammer compactor are greatly simplified, the overall cost is greatly lowered, and the reliability and the stability of the rammer compactor are improved.

Description

technical field [0001] The invention relates to a high-speed hydraulic tamping machine, in particular to a novel high-speed hydraulic tamping machine of a variable stroke separation type. Background technique [0002] my country is currently vigorously developing infrastructure construction, including high-grade highways, high-speed railways, airports, bridges, etc. The construction volume of bridges and culverts, especially culvert structures, has increased sharply; The filling is carried out after the completion of these structures. When filling, it is necessary not only to ensure that the structure of the structure itself is not damaged, but also to have sufficient compactness. Due to the narrowness of the filling place, the operation of large-scale compaction machines is inconvenient, and it is difficult for small-scale compaction equipment to achieve the required compaction degree, so the construction is difficult. [0003] The traditional hydraulic tamping machine ado...
