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 rammer compactor for a road limiting rod. The hydraulic rammer compactor for the road limiting rod comprises a main hollow shell, and a main telescopic space is formed inside the top end of the main hollow shell. According to the hydraulic rammer compactor for the road limiting rod, a high-pressure buffer solution is utilized to achieve the adjustment of the compaction angle, when adjustment is conducted, high-pressure liquid is injected into through holes in rotating parts through a hydraulic pump, and the angle change is achieved under the pressure actionof the high-pressure hydraulic pressure. Meanwhile, the high-pressure hydraulic pressure is utilized to inject the liquid into a telescopic part, the friction force between the rotating parts is changed, rotation is achieved, then the high-pressure liquid is utilized to provide the high tension, the two rotating parts are tightly fixed, the main friction force is provided, the main limiting effectis provided for stabilization of the parts in the working process, and therefore the angle adjusting range of the compaction work is widened.

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 ...
