Problems solved by technology

[0002] At present, it is relatively common to install guardrails on both sides of the road. When installing the guardrails, the fixed columns need to be rammed into the ground. However, the actual tamping device has very poor ability to change the angle when it is working.

Abstract

The invention discloses a hydraulic compactor for a road limit rod, which comprises a main hollow shell, and a main telescopic space is arranged inside the top of the main hollow shell. The invention uses high-pressure buffer fluid to realize the adjustment of the tamping angle. When adjusting, a hydraulic pump is used to inject high-pressure liquid into the through hole in the rotating part, and the angle is changed under the pressure of the high-pressure hydraulic pressure. At the same time, when using High-pressure hydraulic pressure is injected into the telescopic parts to change the friction between the rotating parts to realize the rotation, and then use the high-pressure liquid to provide a strong pulling force to fix the two rotating parts tightly and provide the main friction force to stabilize the parts during work. Provides primary stop action to increase angular adjustment range for compaction work.

Description

technical field [0001] The invention relates to the technical field of tampers, in particular to a tamper for a hydraulic road limit rod. Background technique [0002] At present, it is relatively common to install guardrails on both sides of the road. When installing the guardrails, the fixed columns need to be rammed into the ground. However, the actual tamping device has very poor ability to change the angle when it is working. Contents of the invention [0003] The object of the present invention is to provide a hydraulic compactor for a road limit rod to solve the problems raised in the above-mentioned background technology. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a hydraulic type road limit rod tamper, comprising a main hollow shell, a main telescopic space is provided inside the top of the main hollow shell, the top of the main telescopic space and The center of the bottom end is respectively ...
