Description

Multifunctional tunneling trolley

Technical Field

The utility model relates to an underground coal seam exploitation facility, concretely relates to multi-functional tunnelling platform truck.

Background

The main work of coal mine rock roadway tunneling comprises advanced geological drilling construction, roadway construction and the like; the advanced geological drilling is generally constructed by using a full hydraulic drilling machine, and only a drilling machine with light weight and low power can be used due to the limitation of rock loading transportation equipment and environmental conditions, and the drilling machine has long time for entering and exiting a tunneling working face, high labor intensity, low drilling speed and low comprehensive efficiency. The tunnel excavation process mainly adopts the drilling and blasting construction and the gangue loading of a steel wire rope rock raking machine: the roadway drilling and blasting method for advancing excavation mainly comprises the following working procedures of drilling and blasting: the drilling method comprises manual air hammer drilling and drill jumbo mechanical drilling, the drilling speed of the manual air hammer is low, the labor intensity of workers is high, and the efficiency is low; the drilling jumbo is high in mechanical drilling speed and efficiency, which is 2-3 times of the drilling efficiency of an artificial air hammer, but the drilling jumbo is limited by defects of the drilling jumbo and environmental conditions, so that the drilling jumbo cannot adapt to the requirements of medium and small section roadway tunneling at present, the use of the drilling jumbo in the medium and small section roadway is influenced at present, and the drilling jumbo mainly has two aspects, namely, the working mechanism for drilling is long, the width of the roadway is small, the drilling jumbo is not beneficial to construction of a cut blast hole for forming a free surface, the blasting effect is poor, and the circulation progress is low; secondly, the design of the drill jumbo is not scientific with the design of the rock loader, and the efficiency is low; drilling holes of a drilling and loading machine integrating a rock drilling jumbo with a tunneling drill carriage and rock loading; the tunneling drill carriage is matched with a rock loader to complete the tunneling process of the roadway to form the roadway. The existing tunneling drill carriage is not matched with a rock loading device, the tunneling drill carriage needs to be moved back to a rock loading machine behind the rock loading machine to load gangue before rock loading after blasting, the tunneling drill carriage and the rock loading machine cannot normally converge due to narrow tunnel in a tunnel with a medium-small section, the tunneling drill carriage needs to be moved back to a large-section tunnel before the tunneling drill carriage is moved back, the rock loading machine can return to the original place to load rock after the tunneling drill carriage is moved back, the operation is very complex, the time consumption is long, the efficiency is very low, and meanwhile, as the bottom plate of the tunnel is concave and convex after the rock loading machine goes out of a mine, the tunneling drill carriage is unsafely and stably moved, the bottom plate needs to be manually moved flat while walking, otherwise, the tunnel, pipelines and air cylinders are easily damaged by rollover, safety accidents are caused, and the tunneling drill carriage cannot adapt to drilling in medium-small section tunneling; the drilling and rock loading are integrated in design, but the drilling and rock loading are performed to achieve the design effect, a reliable continuous transportation system is required to be matched with the drilling and rock loading, most roadways of a coal mine do not have the continuous transportation condition, and meanwhile, the drilling and rock loading process of the drilling and rock loading machine cannot be operated in parallel, the efficiency is too low, and the drilling and rock loading machine cannot meet the requirement of tunneling. Therefore, there is a need for improvements to existing ripping equipment.
