A movable lifting platform two-arm top help anchor rod anchor cable construction drilling rig

Abstract

The invention relates to a drilling rig for construction of anchor rods and cables with two arms on a movable lifting platform, which includes a crawler walking part, a body platform, a lifting platform, a platform lifting device, a drilling arm part, a hydraulic drilling rig part, a temporary support device, a hydraulic The operating system, the pumping station part and the main motor; the main feature is that there are two stages of pedals on the lifting platform, which are respectively a primary rotary pedal and a secondary flip pedal; the temporary support device includes a column, an angle adjustment cylinder, and a beam , telescopic oil cylinder, telescopic beam and supporting part; and the lifting platform adopts three lifting oil cylinders and three-point support, four-link integral top beam, parallel movement, vertical lifting and other structures; It also has the functions of construction blasthole, gas discharge hole, water exploration and discharge drilling, better temporary support capacity, ultra-high roadway support and other functions, adopts full hydraulic system transmission, explosion-proof performance and safety Good performance.

Description

technical field [0001] The invention belongs to coal mine underground excavation equipment, and in particular relates to a movable lifting platform two-arm top side anchor rod and anchor cable construction which is suitable for large, medium and small coal mines and is required for continuous mining, continuous excavation, and fully mechanized excavation construction. drill car. Background technique [0002] At present, the main methods of roadway excavation in various coal mines are continuous mining, continuous excavation, and fully mechanized excavation. Body drilling rig or crawler-type liftable roof bolt and anchor cable construction drilling rig, such as the disclosed crawler-type liftable roof bolt and anchor cable construction drilling rig in Chinese Patent No. 200720102731. Type traveling mechanism, advance support; the traveling mechanism is driven by a hydraulic motor, and the drilling rig platform is installed on the frame of the traveling mechanism; A hydrauli...

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 operation. The mine roof bolt and anchor cable construction using continuous mining and continuous excavation technology has basically realized mechanization. The mine roof bolt and anchor cable construction using fully mechanized excavation technology, if it is still manual operation of a single drilling rig, 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 need for two sets of equipment to enter or exit the excavation face in turn during excavation construction, coupled with the dragging of cables, it takes a long time and a large amount of auxiliary work

[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 at high altitude, and the working safety environment is poor.

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