Integrated equipment with supporting and anchoring collaborative operation function

Abstract

The invention relates to the field of fully mechanized excavating working surface electromechanical equipment, in particular to integrated equipment with a supporting and anchoring collaborative operation function. The equipment comprises an aerial rail assembly which takes a top end supporting U-shaped beam as an anchor point to be fixedly suspended on the lower portion of the top end supportingU-shaped beam, and the guide direction of the aerial rail and the tunneling direction are the same. A walking assembly capable of linearly moving in a reciprocating mode in the guide direction of theaerial rail assembly is arranged on the aerial rail assembly, and the walking assembly is provided with a functional part used for achieving the drilling anchoring function and / or a supporting function. The equipment is extremely high in operation flexibility, high in maneuverability in a narrow environment and high in adaptability to the surrounding environment, and can also achieve the paralleloperation effect between construction procedures to the largest extent.

Description

technical field [0001] The invention relates to the field of mechanical and electrical equipment for fully mechanized excavation working faces, in particular to integrated equipment with the function of cooperating with anchor protection. Background technique [0002] With the expansion of the production scale of coal mines and the improvement of coal mining mechanization, the production capacity and advancing speed of the fully mechanized mining face continue to increase, which puts forward higher requirements for the speed and efficiency of bolt digging and support. At present, the roadheader equipment has made great breakthroughs in terms of function and quality, and the intelligence level and work efficiency of the products have been significantly improved. However, in contrast, the development of anchor support equipment is relatively slow, and the speed of anchor support operations is lower than the speed of roadway excavation, that is, fast-drilled roadways cannot be ...

AI Technical Summary

Problems solved by technology

The above-mentioned published patents all disclose that the drilling and anchoring system and the temporary support mechanism are installed on the top of the roadheader, and adopt the crawler ground travel mode, which can realize the mechanized operations of "digging", "anchor" and "supporting", and in a certain To a certain extent, the labor intensity of coal mine workers and the incidence of casualty accidents among coal mine workers can be reduced; however, its shortcomings should not be underestimated: first, the equipment structure is huge and the scope of use is limited

In the existing disclosed all-in-one machine for digging, bolting and protecting, since both the drilling and anchoring equipment and temporary supporting equipment are installed on the roadheader, the overall structure of the equipment is relatively complicated and the size is large, and the space of many underground roadways in coal mines is small, so the all-in-one machine for digging, anchoring and protecting In the process of transportation and installation, there are many inconveniences, and even some mines cannot use such equipment at all

Second, the mobility of the equipment is poor

The above-mentioned all-in-one machines for digging, bolting and protecting all adopt the crawler-type traveling mode. Due to the heavy equipment and the poor geological conditions of the coal mine underground roadway, the maneuverability of the whole set of equipment during the traveling process is poor, and it is difficult for workers to operate.

Third, the coordination ability of each sub-component of the equipment is poor, and the overall work efficiency is not high

The above-mentioned disclosed equipment is only a superposition of simple mechanical structures, and does not fully consider the cooperative operation between the subsystems; for example, the excavation and drilling and anchoring operations of the equipment cannot be carried out at the same time, and the speed of the anchor support operation is lower than that of roadway excavation. speed, etc., so that the overall performance of the system cannot be fully utilized, and the overall work efficiency is not high

Finally, the degree of automation of the rod bolter is not high

The above disclosed drilling and anchoring equipment requires manual work in the process of installing the bolt on the bolting rig. On the one hand, the manual operation speed is relatively slow, which affects the work efficiency of the drilling and anchoring; on the other hand, if the manual installation of the bolt is performed Improper, there will be certain security risks
