Movable two-arm hanging wall anchor rod and anchor cable construction drill carriage

Abstract

The invention provides a movable two-arm hanging wall anchor rod and anchor cable construction drill carriage which mainly comprises a crawler traveling part, a machine body platform, drill arm parts, a hydraulic drill device, a temporary support device and a hydraulic operation system, and is characterized in that the temporary support device comprises a temporary support base, an extension arm,a protection plate, an oil cylinder of the extension arm and an oil cylinder of the protection plate; the temporary support base is arranged on the machine body platform; the extension arm is articulated on the temporary support base; the oil cylinder of the extension arm is articulated on an extension arm seat and the extension arm; the protection plate is articulated at the top end of the extension arm; and the oil cylinder of the protection plate is articulated on the protection plate and the extension arm. The invention lowers the labor intensity of constructors, reduces the number of theconstructors, improves the tunneling speed and the operating efficiency, creates the safe operating environment, and especially has a function of carrying out top pushing type temporary support for ultrahigh tunnels and the head-on coal sides of working surfaces.

Description

technical field [0001] The invention relates to coal mine underground excavation equipment, which is suitable for large, medium and small coal mines, and is a roof bolt and anchor cable construction machine required for continuous mining, continuous excavation, and fully mechanized excavation construction of various roadways. Background technique [0002] At present, the main methods of roadway excavation in various coal mines are continuous mining, continuous excavation and fully mechanized excavation. Using a single drilling rig, there is also a crawler-type liftable roof bolt and anchor cable construction drilling rig, such as the crawler-type liftable roof bolt and anchor cable construction drilling rig disclosed in Chinese Patent No. 200720102731.2. Support, crawler-type traveling mechanism, advanced support; the traveling mechanism is driven by a hydraulic motor, and the drilling rig platform is installed on the frame of the traveling mechanism; The front end is equip...

AI Technical Summary

Problems solved by technology

[0004] 1. The tunnel excavation section is small: the excavation section is generally 15M 2 Left and right, when the height of the roadway exceeds 2 meters, scaffolding must be set up to carry out the construction of the roof anchor rod and anchor cable

[0005] 2. Non-mechanized operations. The construction of mine roof bolts and cables using continuous mining and continuous excavation technology has basically realized mechanization. All the excavation processes of bolt and anchor cable construction are carried out by hand-held pneumatic drills. The thrust of the drilling comes from the human arm and arm, and the labor intensity of the workers is high.

Since the construction of the anchor bolts and cables mainly relies on manpower, the construction quality of the anchor bolts and cables cannot be guaranteed fundamentally.

[0006] 3. The construction speed is slow, and it takes a lot of time to build and dismantle scaffolding when the construction section exceeds 2 meters

[0007] 4. Low efficiency: Due to the large number of drilling holes and the large number of construction workers, the operation efficiency is low

[0008] 5. Low safety factor: construction workers work alternately at high altitude, and the working safety environment is poor

[0011] 2. It takes a long time to advance and retreat the machine, and the auxiliary workload is large

Due to the excavation construction, two drilling rigs need to be driven into or out of the excavation face in sequence, coupled with the dragging of the cable, the time is long and the auxiliary workload is large

[0012] 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 drilling rig cannot complete the construction of gas prediction holes, gas discharge holes, geological detection holes, and vibration blastholes

[0013] 4. The construction of roof anchor rod and anchor cable can not reach zero lag, which is unfavorable to the control of road side

[0014] 5. The workload of the roof bolt and anchor cable construction does not match, the workload of the top drill is large, and the workload of the side drill is small, which affects the support time and causes personnel to work idle

[0015] 6. The construction workers are working alternately at high altitude, and the working safety environment is poor

[0016] 7. There are a lot of people, two drilling rigs need to be equipped with 8 people
