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

Abstract

The invention provides a movable two-platform partitioned four-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 part, a temporary support device, a hydraulic operation system, a pump station part and a main motor, and is characterized by also comprising a lifting platform and a platform lifting device, wherein the platform lifting device is installed on the machine body platform, the lifting platform is connected on the platform lifting device, and the drill arms are respectively arranged at the upper part and the lower part of the lifting platform and the left side and the right side of the lifting platform. The operation and the construction of a roadway support are simultaneously carried out in an upper region, a lower region, a left region and a right region in a double-layer partitioned way, thereby shortening the working time and improving the support efficiency. The drill carriage of the invention can be used for carrying out top pushing type temporary support on the heads of working surfaces especially aiming at highly gassy mines and mines with complicated geological conditions, and simultaneously can be used for carrying out construction of gas prediction holes, gas discharge holes and geological exploration holes.

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. 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 hydraulic cylinder-type advance support, one side of the advanc...

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.
