Description

A Drilling and Anchor Integrated Machine with a Full-Section Drilling Telescopic Platform

technical field

The invention relates to a dual-arm drilling (anchor) integrated machine, in particular to a telescopic platform capable of realizing full-section drilling with a single arm, which is suitable for narrow roadways such as coal mines or non-coal mines.

Background technique

At present, on roadway excavation construction equipment such as coal mines or non-coal mines, the current dual-arm drilling and anchoring integrated machine and the dual-arm drilling and anchoring integrated machine do not move. There is interference. When the left arm or the right arm is drilling alone, it can only drill three-fifths or less of the head-on blast holes of the roadway section, and cannot realize the full-section drilling of the roadway. For example, Sany Heavy Equipment, Shijiazhuang Such products are produced by China Coal, Shanghai Founder and other enterprises. However, mechanical products will inevitably have quality failures. Since each working arm can only punch holes in more than half of the roadway section, when any working arm in the dual-arm model has a quality failure, manual work is required. To carry out the remaining drilling operations, if the equipment is in normal condition, the manpower can be reduced. Once a mechanical failure occurs, no man can be found, and the production efficiency will be lower, which will not achieve the goal of mechanization and manpower reduction.

Contents of the invention

In view of the fact that the current double-arm drilling (anchor) integrated machine does not have a single-stage or multi-stage telescopic (including fixed) platform structure, the present invention provides a multi-stage telescopic platform structure, which is arranged on the slideways on both sides of the drilling (anchor) unit. Telescopic, lifting and lowering of the tank body in front of the transport tank, positioning of the push plate, installation and adjustment of the gantry structure of the excavating arm, and deflection of the excavating arm, so as to achieve the purpose of full-section drilling with a single arm.

The invention provides a novel telescopic (including fixed) platform structure in a dual-arm drilling (anchor) integrated machine. The telescopic platform is integrated with the vehicle frame through a flange mounting seat and positioning pins, and the connection is safe and reliable.

The technical solution adopted by the present invention is: a drill-installation-anchor integrated machine with a telescopic platform for full-section drilling, which includes a vehicle frame, a drill arm mechanism, a conveying tank, an excavating arm and a crawler walking mechanism. One side or both sides of the working arm is provided with a telescopic platform, and the telescopic platform includes a fixed platform fixed on the vehicle frame and a telescopic extension platform connected with the fixed platform, and the extension platform is connected to the flat platform through the drill arm connection seat. The moving oil cylinder is connected with the arm translation oil cylinder, and the translation oil cylinder and the arm translation oil cylinder are respectively connected with the swing oil cylinder. The fixed platform is equipped with a rear bolter, and the extended platform includes at least one telescopic tube, and one end of the telescopic tube is provided with a drill arm or a bolt arm mounting seat, and the telescopic tube is connected to the set by the piston push rod. The hydraulic cylinders in the fixed platform are connected.

The structural features of the present invention are:

1. When the drilling boom is extended to work, the extended length of the telescopic platform is about to extend all the multi-section telescopic beams with the drilling boom to the limit, that is,

Extend to the appropriate distance between the slewing seat of the excavating arm and the boom (including the limit position of the fixed platform forward extension). At this time, the operator can clearly see the middle and lower parts within three-quarters of the front when the forearm is extended to the front of the roadway top. On the working surface, when the forearm is stretched forward and falls on the bottom of the roadway, you can clearly see the middle and upper working surface within two-thirds of the front. Lift the front shovel through the front tank to support the telescopic platform to form a "floating support point" , can significantly increase the stability of the telescopic (including frame fixing) platform.

2. After forming a stable telescopic platform (including the trolley traveling to the limit position of the fixed platform), the operator on the telescopic platform realizes the above-mentioned line of sight. At this time, the excavating working arm and the telescopic platform have been able to achieve misalignment, avoiding the sight of structural parts Interference with movement, the drilling arm installed on the front of the telescopic beam of the telescopic platform can also rotate at a larger angle. Through the lifting and landing of the excavating arm, a single arm can cover the entire roadway section (including the front and top) blast holes or anchors pole eye. If this structure is adopted, mechanization can be realized to reduce manpower, and the efficiency of drilling and excavation can be obviously improved.

3. When carrying out slag removal and loading operations, the telescopic beam of the telescopic platform shrinks (or the trolley retreats on the slideway), and the drill arm assembly retracts, giving way to a large space for the excavating arm, so that the excavating arm swings left and right It is also larger, with a larger slag loading range than traditional models, and can carry out full-section slag loading operations.

The present invention utilizes the expansion and contraction of the telescopic platform to "give up" a large space for the excavating working arm, so that the left and right yaw angle of the excavating working arm is also larger, and the drilling arm installed at the front of the telescopic beam of the telescopic platform can also rotate Larger angle, through the lifting and landing of the excavating arm, a single arm can cover the entire roadway section (including the head and the top) blast hole or anchor hole, which is larger than the traditional model and can carry out full-section excavation. The slag loading operation realizes mechanization to reduce manpower and improves the efficiency of drilling and excavation.
