Movable three-arm top-assisting anchor rod and anchor cable construction drill carriage

Abstract

The invention relates to a movable three-arm top-assisting anchor rod and anchor cable construction drill carriage which comprises a caterpillar travelling part, an engine body platform, a base seat, drilling arm parts, hydraulic drill rig devices, an operating system, a pump station part and an electric motor, wherein the hydraulic drill rig devices are arranged on the tops of the drilling arm parts; the operating system, the pump station part, the electric motor and the like are installed at the rear on the engine body platform; the construction drill carriage is characterized in that the construction drill carriage is provided with three sets of independent drilling arm parts and hydraulic drill rig devices which are respectively arranged at the left, the middle and the right of the base and are installed on the base; the base is fixedly arranged on the engine body platform; and the drilling parts and the hydraulic drill rig devices which are arranged at the left and the right sides can slide outwards. The construction drill carriage lightens the labor intensity of constructors, reduces the number of the constructors, improves the advancing speed and the operation efficiency, creates safe operation environment, and has the functions of automatically moving, lifting, double platforms, synchronous construction of top-assisting anchor rod and anchor cable, ultrahigh laneway supporting and protecting, etc.

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. The support methods are bolts, anchor cables, joists, and anchor nets. Drilling rig or crawler type liftable roof bolt and anchor cable construction drilling rig, such as Chinese Patent No.: 200720102731.2 disclosed crawler type liftable roof anchor bolt and cable construction drilling rig, there are two drilling rig devices, one advance support, crawler type The traveling mechanism is advanced support; the traveling mechanism is driven by a hydraulic motor, and the drilling...

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
