Description

Rotary mechanism for guardrail rush-repair vehicle Technical Field The utility model relates to the technical field of guardrail emergency repair vehicles, in particular to a slewing mechanism for a guardrail emergency repair vehicle. Background Along with the rapid development of highway traffic, the guardrail is used as an important facility for guaranteeing driving safety, and the rush-repair efficiency directly influences the road traffic capacity. At present, a guardrail rush-repair vehicle is commonly provided with a pile driving and pulling device for quickly replacing damaged guardrail piles. Because the guardrail rush-repair car is driven to the nearby guardrail, the vehicle is in the left side of damaging the guardrail, in order to switch the pile driving device from the storage state to the working state, the whole pile driving device is required to be driven to rotate by the rotary mechanism, so that the pile driving device can face the guardrail. The instrument control box of the pile driving device is usually fixed on the vehicle body, and is usually positioned at a position close to the vehicle head in order to avoid interference with the pile driving device, so that the instrument control box is far away from the hammer head part of the pile driving assembly, and an operator can conveniently operate while checking the position of the hammer head. Disclosure of utility model Aiming at the technical defects, the utility model aims to provide a slewing mechanism for a guardrail rush-repair vehicle, which can stably drive a pile driving assembly to rotate on the guardrail rush-repair vehicle and is convenient to operate by using an instrument control box. In order to solve the technical problems, the utility model provides a slewing mechanism for a guardrail rush-repair vehicle, which comprises the following components: The rotary upper bracket is used for installing a pile driving assembly; the rotary lower bracket is fixedly connected with the chassis of the guardrail rush-repair vehicle; The rotary support comprises an outer ring fixedly connected with the rotary upper bracket and an inner ring fixedly connected with the rotary lower bracket, and the outer ring is rotationally connected with the inner ring; the instrument control box is used for controlling the pile driving assembly to work and is fixed on the rotary upper support through the connecting arm.
