Multi-functional arching mounting trolley

Abstract

The invention discloses a multi-functional arching mounting trolley. The multi-functional arching mounting trolley includes a trolley body, the trolley body is provided with a main placing boom and anauxiliary placing boom, wherein the main placing boom and the auxiliary placing boom have rotary, telescopic and pitching functions; an arching clamping device is arranged on the end part of the mainplacing boom; the end part of the auxiliary placing boom is provided with an operating basket and / or a rock face crushing device and / or a grabbing lifting arm; and the grabbing lifting arm is used for grabbing an arching and lifting heavy objects. According to the multi-functional arching mounting trolley, tunnel rock face under-excavation faces can be processed, the arching can also be stably clamped, and components and parts can also be lifted to upper air when the components and the parts are forgotten or lost.

Description

technical field [0001] The invention relates to the field of tunnel construction, in particular to a multifunctional arch installation trolley. Background technique [0002] In recent years, my country's underground engineering has developed rapidly, and mechanized operations have gradually been widely used in engineering technology, especially in the field of underground tunnel construction. [0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches is mainly carried out by manpower. It has the following disadvantages: 1. The number of workers required is large, and the labor intensity Large size and low efficiency. Existing arches are mostly connected by flanges and sleeves. When on-site installation requires a lot of manual construction; 2. Existing arch constructions cannot cooperate with mechanized on-site construction of arches. [00...

Problems solved by technology

[0003] At present, in the process of tunnel construction, steel arches need to be erected on the excavated rock face. The traditional steel arches are heavy, and the installation of the arches is mainly carried out by manpower. It has the following disadvantages: 1. The number of workers required is large, and the labor intensity Large size and low efficiency. Existing arch frames are mostly connected by flanges and sleeves. When on-site installation requires a lot of manual construction; 2. Existing arch frames cannot match the mechanized on-site construction of arch frames

The hydraulic breaker is heavy, and it will vibrate during the construction process. The work fatigue of the construction personnel will be very high, and the construction personnel will work at high altitude for a long time, which will reduce the construction efficiency and bring safety hazards.

[0006] At the same time, when the construction personnel are installing the arch, sometimes due to the lack of parts or tools, they must not get down from the height to take it.

This reduces the construction efficiency and increases the artificial fatigue strength
