Thousand-palm compound wagon drill

Abstract

The invention discloses a thousand-palm compound wagon drill. A wheel type or crawler-type carrying tool is used for carrying multiple types of equipment; an engine which is used for driving the carrying tool to move and can be used for supplying power to a hydraulic device of the carrying equipment is arranged; the carrying tool is provided with a cab; a control device for the carrying equipment is arranged in the cab; a plurality of groups of drilling and blasting devices are arranged on a chassis of the carrying tool; and auxiliary attachments are arranged. The thousand-palm compound wagon drill is characterized in that: the drilling and blasting device is provided with a horizontal tube support (3) which can be moved forwards and backwards; the tube support is supported by using the chassis; one front end of the tube support is fixedly connected with a palm type end face; a plurality of groups of drill hammer drilling fingers are arranged on the palm type end face along the circumferential edge of a circular disk (4), so that supporting, positioning and propelling of a drill hammer are realized; and a rotary crane boom is arranged at the back end of the tube support, so that initial lining and spraying anchorage delivery operation of tunnels are completed.

Description

technical field [0001] The invention relates to a rock drilling jumbo for tunnel construction, in particular to a thousand-hand composite rock drilling jumbo for simultaneous construction at multiple points at the same time. Background technique [0002] Drilling and blasting methods are mostly used in tunnels. It is common to use rock drilling rigs to drill holes in tunnel construction. However, most of the known rock drilling rigs have fewer drilling rigs that can work at multiple points at the same time, and cannot adapt to more complicated tunnel construction conditions. Therefore, it is necessary to improve the existing rock drilling rigs. At present, the advanced multi-arm trolleys in the world, such as: Japan's nine-arm trolley can only complete nine eyes at the same time, and its own weight is too heavy. In China, XCMG three-arm trolleys are all expensive, and they are constructed by drilling and blasting. In the application, the concept of the arm is adopted, which...

Problems solved by technology

At present, there is only one-armed trolley on the market, and it is 30m 2 For the large tunnels with the above sections, there are currently nine-arm trolleys on the market, and fixed hydraulic trolleys with door-type multi-point simultaneous drilling, but they are stereotyped trolleys, and the repeated use rate is low, which will increase the cost and weigh more than 100 tons.

Looking at all the trolleys in the world, none of them have realized the concept of simultaneous operation of the two processes of "drilling" and "primary lining"
