Drilling, loading, transporting and anchoring integrated machine with dual platforms and four arms for coal roadway

Abstract

The invention provides a drilling, loading, transporting and anchoring integrated machine with dual platforms and four arms for a coal roadway, comprising a caterpillar travel part, an engine body platform, four drill arm parts, four hydraulic drilling rig parts, a provisional supporting device, a hydraulic and operation system, a pump station part, a rear support part, a shovel plate part, a first conveyor and a second conveyor and being characterized in that the integrated machine also comprises a lifting platform and a platform lifter; the platform lifter is arranged on the engine body platform, and the lifting platform is connected above the platform lifter; four drill arm parts and four hydraulic drilling rig parts are installed at the rear sides of the upper and lower parts and the left and right sides of the lifting platform; and the provisional supporting part is fixedly installed on the front end of the lifting platform. The integrated machine in the invention can complete all procedures such as drilling, coal loading, coal transporting, anchor bolts and anchor cables construction, provisional supporting and the like, and improves the centrality, flexibility and systematicness of tunneling equipment, thus reducing mechanical handing, installing and dismounting operations on headwork faces, lowering labor intensity for workers and increasing work efficiency of tunneling.

Description

technical field [0001] The invention relates to coal mine underground mechanical equipment, in particular to a coal roadway double-platform four-arm drilling, loading and anchoring integrated machine suitable for large, medium and small coal mine roadway opening and chamber driving. Background technique [0002] At present, the roadway excavation of various coal mines in my country generally adopts blasting excavation, fully mechanized excavation and continuous mining and other excavation technologies. An existing coal roadway drilling, loading and anchoring integrated machine, such as Chinese Patent No.: 200820125012.7 provides a coal roadway drill The integrated machine for shipping and anchoring mainly includes the crawler walking part and the scraper conveyor part, a temporary support part, two drilling rig parts that can lift and swing the roof anchor rod and anchor cable, and the hydraulic pressure and operating system; the transportation part It is composed of rake claw...

AI Technical Summary

Problems solved by technology

[0004] Although this machine has many advantages, it can swing within a certain range to achieve the purpose of reloading. It can realize front and rear telescopic, left and right swing, and rotation in three directions. It is very flexible, convenient and fast to complete blastholes and roof bolts Anchor cable construction; however, with the continuous improvement of coal mining technology requirements, the machine still has many deficiencies and problems

[0005] 1. The structure of the hydraulic drilling rig of this machine is relatively complex, the mechanism is large and heavy, and there are many friction pairs, which are relatively prone to failure

[0006] 2. The working platform is too small. With the construction drilling rig mentioned above, the operation and working space of the construction operators is small, the working safety conditions and environment are poor, and the safety factor is low. It is impossible to work staggered at high altitude, causing people to stop working and resulting in low work efficiency

[0007] 3. Poor adaptability to complex geological conditions

In case of complex geological conditions such as faults, high gas areas, and high water content areas, the machine cannot complete the construction of gas prediction holes, gas discharge holes, geological detection holes, and vibration blastholes.
