Vibrating slab tamper

Abstract

The invention discloses a vibration flat rammer, which is characterized by the following: setting motor on the frame and armrest on the armrest seat; fixing flange on the motor; setting arm seat absorber and absorber protector between armrest seat and upper installment plate; fixing the loading system on the rack lower installment plate; setting pulley box with driving structure in connection with the motor and loading system on the installment flange; adapting front eccentric block, middle eccentric block and back eccentric block in the loading case to generate exciting force to compact ground foundation through motor driving system; setting lubrication system in the loading case to lubricate the operation part and reduce noise. The invention adapts universal joint as driving part, which avoids the rigidity driving shaft breakdown phenomenon.

Description

technical field [0001] The invention belongs to the technical field of paving and repairing machines, tools or auxiliary equipment for pavement of roads or other similar structures, and in particular relates to vibratory flat compactors. Background technique [0002] At present, in the compaction of narrow areas in construction projects, the frog type ramming machine developed in the 1960s is still widely used, and its structure is simple and the production cost is low. The main disadvantage of the frog-type ramming machine is that the ramming effect is poor, which can no longer meet the requirements of use. It is required that the thickness of the paved soil layer cannot be deep, and the productivity is not high. The stress-bearing parts often break, and the connecting bolts on the tamp head frame are easy to loosen under continuous impact. If they are not checked frequently, the eccentric block will fly out and cause accidents such as injury. During the construction proces...

Problems solved by technology

The main disadvantage of the frog-type ramming machine is that the ramming effect is poor, which can no longer meet the requirements of use. It is required that the thickness of the paved soil layer cannot be deep, and the productivity is not high. The stress-bearing parts often break, and the connecting bolts on the tamp head frame are easy to loosen under continuous impact. If they are not checked frequently, the eccentric block will fly out and cause accidents such as injury. During the construction process, the noise is loud, Especially construction in residential areas has become a well-known public hazard

In addition, the frog-type ramming machine has a high labor intensity for the operator during use, and the transmission belt 15 is prone to failure due to the periodic change of the exciting force of the eccentric block, and needs to be replaced frequently, and disassembly and assembly are more troublesome

[0003] At present, the vibratory plate compactor used on the construction site uses two vibrating shaft exciters, and the two vibrating shafts rotate in reverse, which limits the power of the vibratory plate compactor.

Most of the structural settings are that the eccentric excitation device is arranged at the front of the complete machine, and the power device is arranged at the rear of the complete machine. The weight of the power device is greater than the weight of the eccentric excitation device, which is likely to cause uneven weight distribution of the complete machine in terms of structural settings. Even, resulting in uneven compaction

[0004] Impact rammers, one-way vibratory plate compactors and two-way plate compactors produced in the United States are large in size, fast in compaction speed, and high in compaction efficiency. These compactors can only compact large-area foundations. Work cannot be done in smaller tunnels, and these rammers are expensive to sell
