Description
[0001] The present invention relates to the technical field of mining machinery, and in particular, to an excavating, supporting and anchoring integrated machine system for downhole rapid excavation and a use method thereof.
[0002] As the mining depth of a production mine is increasing, a ground stress and a surrounding rock stress and deformation are complex and diverse. An anchor net support is used by a majority of tunnel mining because of a good supporting effect, a wide range of application, flexibility in adapting to changes according to tunnel conditions, and other features of the anchor net support. However, in a current process of tunnel excavation, a mechanized excavation efficiency is very high, and a tunnel support speed lags far behind an excavation speed. Due to a serious mismatch of the excavating time, supporting time and anchoring time, a footage time of an excavating machine is far less than a total working time, and in a large amount of time, the excavating machine stops operating for performing a support operation. One direction to resolve the serious mismatch of the excavating time, supporting time and anchoring time is to implement an excavating, supporting and anchoring parallel operation.
[0003] A patent entitled "UNMANNED TUNNEL EXCAVATION AND ANCHORING INTEGRATED MACHINE" is disclosed in CN104500086A. A support system thereof only involves temporary support and anchor rod support, and cannot resolve a problem of falling of small pieces of surrounding rock. If an anchor net needs to be installed, a working section needs to be manually approached, and a cutting head needs to be stopped for safety of workers. Therefore, the excavating, supporting and anchoring parallel operation cannot be implemented, and dust, noises and other factors also greatly threaten the safety of the workers. A cutting unit thereof can perform cutting by only one feed each time the cutting unit stops to operate, and the efficiency is relatively low.
Technical Problem
[0004] To resolve the foregoing problem, the present invention provides an excavating, supporting and anchoring integrated machine system for downhole rapid excavation.
Technical Solution
[0005] To achieve the foregoing objective, the present invention adopts the following technical means:
[0006] The present invention provides an excavating, supporting and anchoring integrated machine system for downhole rapid excavation, including an excavation machine having an elongate body extending along a longitudinal axis, where a cutting unit used for cutting a section, an anchoring and supporting unit capable of free or flexible movement, working at a plurality of angles, and used for driving an anchor rod on the cut section, and a baffle unit functioning as a temporary support and protecting the anchoring and supporting unit are disposed on the elongate body of the excavation machine.
[0007] Further, the cutting unit includes a cutting unit bottom plate welded on the elongate body of the excavating machine, a cylindrical slide rail is disposed on the cutting unit bottom plate, a first sliding block is correspondingly disposed on the cylindrical slide rail, the first sliding block is connected to a base, a feed hydraulic cylinder is connected between the base and the cutting unit bottom plate, the base is hinged with a swing member being able to swing left and right, the swing member is driven by using a swing hydraulic cylinder connected to the base, the swing member is hinged with a cutting head being able to pitch up and down, and the cutting head is driven by using a pitching hydraulic cylinder connected to the swing member; the anchoring and supporting unit includes an anchoring and supporting unit bottom plate welded on two sides of the elongate body of the excavation machine, the anchoring and supporting unit bottom plate is connected to a feed sliding block through a slide rail, the feed sliding block is hinged with a pitching slide rail being able to pitch up and down, a pitching sliding block is correspondingly disposed on the pitching slide rail, the pitching slide rail is driven by using an anchoring and supporting unit pitching hydraulic cylinder installed on the feed sliding block, a second rotary motor is disposed on the pitching sliding block, the second rotary motor is hinged with a first rotary motor, a motor hydraulic cylinder driving the
DESCRIPTION first rotary motor to pitch up and down is disposed on the second rotary motor, and the first rotary motor is connected to an anchor rod drilling machine through an anchor rod drilling machine sliding block; and the baffle unit includes a baffle bottom plate welded on a rear side of the elongate body of the excavation machine, a baffle slide plate is slidably disposed on the baffle bottom plate through a baffle slide rail, the baffle slide plate is driven to slide by using a baffle unit advancing and retreating hydraulic cylinder installed on the baffle bottom plate, the baffle slide plate is hinged with afirst baffle being able to pitch up and down, the first baffle is driven by using a baffle pitching hydraulic cylinder installed on the baffle slide plate, the first baffle is hinged with a second baffle for facilitating in anchor net installation and use as a temporary support, and the second baffle is driven to level by using a baffle leveling hydraulic cylinder installed on the first baffle.
[0008] Different from a cutting unit of a general excavation machine, the cutting unit may perform a feed movement and may feed more while stopping to operate, so as to improve the operation efficiency. A first rotary motor, a second rotary motor, and a motor hydraulic cylinder together form a humanoid wrist joint, so that an anchor rod drilling machine is more flexible to operate and can better adapt to the downhole complicated working environment.
[0009] Further, each of the feed hydraulic cylinder, the swing hydraulic cylinder, the pitching hydraulic cylinder, the anchoring and supporting unit pitching hydraulic cylinder, the baffle leveling hydraulic cylinder, the baffle pitching hydraulic cylinder, and the baffle advancing and retreating hydraulic cylinder is a servo hydraulic cylinder, so that negative feedback control may be implemented. The first rotary motor and the second rotary motor control a rotation angle by using a rotary encoder, which may make the control more accurate.
[0010] Further, a shape of a front portion of the second baffle is a cambered net, which may better fit a shape of a top of a tunnel on one hand, and may drive an anchor rod into a top plate and a side wall of the tunnel through the second baffle on the other hand.
[0011] Further, a pitching movement of the first baffle operates synchronously with a leveling movement of the second baffle, so that the work efficiency may be increased.
[0012] Further, an operating amplitude of the base is 0 mm to 2000 mm, a swing amplitude of the swing member is -35 degrees to 35 degrees, a pitching amplitude of the
DESCRIPTION cutting head is -15 degrees to 35 degrees, a movement amplitude of the baffle slide plate is 0 mm to 2000 mm, a pitching amplitude of the first baffle is 10 degrees to 80 degrees, and an adjustment amplitude between the second baffle and the first baffle is 120 degrees to 180 degrees.
[0013] The present invention further provides a method for using the foregoing system, the method specifically including the following steps:

[0017] (d) after the cutting head completes a round of S-shaped section cutting, the feed hydraulic cylinder extending for a specific distance, to perform a next round of S-shaped section cutting, and at the same time, the second rotary motor of the anchoring and supporting unit swinging counterclockwise by a specific angle, to drive a next anchor rod;
[0018] (e) after the anchoring and supporting unit completes anchor rod driving on a
DESCRIPTION section, the baffle slide plate moving backward, the baffle slide plate exiting the temporary support, and the feed sliding block moving forward, to perform anchor rod support of a next section; and
[0019] (f) after the cutting head completes a second round of S-shaped section cutting, the feed hydraulic cylinder contracting, the cutting head returning to an initial position, the feed sliding block of the anchoring and supporting unit moving backward to an end, the anchoring and supporting unit pitching hydraulic cylinder, the first rotary motor, the second rotary motor, and the motor hydraulic cylinder acting together, the anchoring and supporting unit returning to an initial position, the front support and the rear support of the elongate body of the excavation machine retracting, and the elongate body of the excavation machine moving forward to a next section of the tunnel, to repeat actions of steps (a) to (f).
Advantageous Effect
[0020] Beneficial effects of the present invention are as follows:
[0021] A structure of the present invention is simple in which the cutting unit may perform a feed movement and may feed more while stopping to operate, so as to improve the operation efficiency. A first rotary motor, a second rotary motor, and a motor hydraulic cylinder together form a humanoid wrist joint, so that an anchor rod drilling machine is more flexible to operate and can better adapt to the downhole complicated working environment. By means of the protection plate structure, the problem that the excavating time, supporting time and anchoring time are not matched in the existing tunnel excavating process is solved, and the excavating efficiency is greatly improved.
