Description

Technical Field

[0001] This invention belongs to the field of rock drilling technology, specifically relating to a rock drilling device for installing mountain protection nets. Background Technology

[0002] When installing mountain protection netting, drilling into the rock mass is mainly to create anchor bolt holes so that anchor bolts can be fixed in the rock mass, thereby ensuring the stability of the protection netting.

[0003] The requirements for drilling in rocky terrain during the installation of protective netting include the following: Anchor holes must be drilled to the depth specified in the drawings to ensure drilling quality. Drilling should be done at a uniform speed, strictly controlling the drilling rate to prevent bending and deformation of the borehole. After reaching the required depth, drilling should continue uninterrupted for 1-2 minutes after stopping the advance to ensure a smooth borehole wall.

[0004] The traditional method is to manually drill into the rock mass using a handheld drilling machine. However, because the drilling speed and direction are controlled manually, the drilling stability is difficult to ensure. In addition, the borehole diameter is generally greater than 45mm, so workers not only need to be attached to the hillside by a traction rope, but also need to hold the handheld drilling machine to drill into the rock mass, resulting in low drilling quality assurance.

[0005] Therefore, it is necessary to develop a rock drilling device that can control the drilling depth and drilling direction in the rock mass and has high drilling stability. Summary of the Invention

The rotating mechanism is equipped with a drilling mechanism and a ash removal mechanism on both sides. The rotating mechanism is used to change the position of the drilling mechanism and the ash removal mechanism. The drilling mechanism is used to drill down the slope rock and soil, and the ash removal mechanism is used to rotate and discharge the rock and soil in the borehole.

[0059] Referring to Figure 15 The development board 61 includes a liquid level signal receiving module, a distance signal receiving module 1, a distance signal receiving module 2 and a pressure signal receiving module. The liquid level signal receiving module is used to receive the liquid level signal input by the liquid level sensor 46 in real time. The distance signal receiving module 1 is used to receive the distance signal input by the distance sensor 1 32 in real time. The distance signal receiving module 2 is used to receive the distance signal input by the distance sensor 50 in real time.

[0062] During the processing of the signal analysis processing module, the real-time liquid level value q received by the liquid level signal receiving module is compared with the liquid level action value f, wherein f=1 cm, when q>f, the signal analysis processing module sends the control signal of keeping the electromagnetic valve 49 open to the integrated relay 59, and when q≤f, the signal analysis processing module immediately sends the control signal of closing the electromagnetic valve 49 to the integrated relay 59 and immediately sends the stop operation instruction of the sub-drilling slurry pump 45 to the integrated relay 59.

[0063] In addition, the signal analysis processing module receives the real-time input tension signal of the tension sensor 25 and converts the tension signal into a tension value, wherein the signal analysis processing module stores the non-cutting tension value j, the non-straight cutting tension value k and the bottom touch tension value h, j is the tension value when the cutting edge of the drilling mechanism does not touch the rock slope, h is the tension value when the bent stirring blade 31 of the ash removal mechanism touches the bottom, wherein the tension value H obtained by the tension sensor 25 on the ash removal mechanism in real time and the tension value J obtained by the tension sensor 25 on the drilling mechanism in real time.

[0064] Wherein, k-j=110N, when drilling normally, J≤(k-20)N.

When J > j and J≤(k-20)N, the n value is obtained instantaneously and is taken as the initial zero value.

A 2-second delay is added, the signal analysis processing module issues the control motor two 18 rotor shaft forward rotation 0.5 rotation instruction to the steering and rotation numerical control module three, and after the running is completed, the control electric telescopic rod two 24 retraction instruction is issued to the steering and rotation numerical control module four and the control motor three 27 running instruction is issued to the relay control module two. When the signal analysis processing module obtains H = h, the control electric telescopic rod two 24 extension instruction is issued to the steering and rotation numerical control module four. When the electric telescopic rod two 24 is extended to the reset position, a 1-second delay is added, and the control motor three 27 stop running instruction is issued to the relay control module two.

[0067] In this process, when J≥k, the running stop drilling program is executed, the signal analysis processing module issues the control motor four 35 running instruction to the relay control module two and the control electric telescopic rod three 33 stop running instruction to the steering and rotation numerical control module four. A 3-second delay is added, the control electric telescopic rod three 33 retraction running instruction is issued to the steering and rotation numerical control module four, and the unexecuted stroke is continued to be executed. When J≥k and the running stop drilling program is executed for 3 times and the drilling is still not continued, the control electric telescopic rod three 33 extension instruction is issued to the steering and rotation numerical control module four, and the electric telescopic rod 33 is extended to the initial position. At this time, the worker can check the bottom composition in the hole and decide whether to continue drilling at this position.

Then the signal analysis processing module instructs the steering rotation control module three to control the motor two 18 to rotate the rotor shaft in the forward direction by 0.5 turns. After running, the steering rotation control module four is instructed to control the retraction of the top rod of the electric telescopic rod three 33, and the relay control module two is instructed to control the motor four 35 to run. Until the top rod of the electric telescopic rod three 33 is retracted to the first retraction length, delay for 5 seconds, and the steering rotation control module four is instructed to control the extension of the top rod of the electric telescopic rod three 33. Until the top rod of the electric telescopic rod three 33 is extended to the initial position, delay for 2 seconds, and the signal analysis processing module instructs the steering rotation control module three to control the motor two 18 to rotate the rotor shaft in the forward direction by 0.5 turns. After running, the steering rotation control module four is instructed to control the retraction of the top rod of the electric telescopic rod two 24, and the relay control module two is instructed to control the motor three 27 to run.

If not, repeat the above drill-out procedure until b = n-m.

[0070] Under such a setting, not only can the drilling depth control effectiveness be effectively guaranteed, but also the rock dust particles in the drill hole can be effectively discharged, providing convenience for the subsequent installation of anchor rods.

[0075] The industrial computer 57 issues a control command to retract the first electric telescopic rod 5, and the first electric telescopic rod 5 drives the pressing piece 7 to move downward. When the pressing piece 10 is pressed against the inner wall of the hole, the industrial computer 57 issues a control command to stop the operation of the first electric telescopic rod 5. Then, the industrial computer 57 issues a control command to operate the first motor 15, and drives the movable plate 12 to move horizontally in the climbing frame 1 until the drill rod 52 is aligned with the position to be drilled.

[0077] The working principle of the embodiment is as follows:

[0078] During the whole operation process, two workers wear safety ropes, and the drilling device is pushed down along the mountain slope to assist the operation, and during the whole operation process, the two workers are mainly responsible for the positioning of the drilling device, the insertion of the pressing piece 10 into the drilled hole, and the operation of the industrial computer 57.

[0079] The blocking and inserting mechanism: the top rod of the electric telescopic rod 5 is retracted, and the pressing piece 7 continuously supports the two side pressing edges 10 outward, forcing the effective pressure of the two side pressing edges 10 in the hole, thereby stabilizing the state of the drilling device on the mountain slope.

[0080] The moving platform, the rotating mechanism, the drilling mechanism and the ash removal mechanism: through the driving of the moving platform, the rotating mechanism, the drilling mechanism and the ash removal mechanism are driven to move along the climbing frame 1, so that not only the distance selection drilling is satisfied, but also the blocking and inserting operation of the blocking and inserting mechanism is performed once, that is, the drilling operation on multiple positions is implemented; through the setting of the rotating mechanism, the drilling mechanism and the ash removal mechanism are quickly switched; through the drilling mechanism, the mountain rock can be effectively drilled, and the ash removal operation of the ash removal mechanism can make the rock powder particles in the hole be effectively cleaned out, and the inner wall of the hole can be made more clean, thereby providing convenience for subsequent glue pouring and anchor rod insertion.

[0081] The rotating mechanism, the drilling mechanism, the ash removal mechanism and the control mechanism: under the control of the control mechanism, the drilling mechanism can be automatically drilled with depth flushing lubrication, and the rotating ring mechanism is automatically controlled to be switched to the ash removal mechanism to perform rapid ash removal operation in the hole, so that the drilling depth, the continuity of the inner wall of the hole and the cleanliness of the hole can be effectively guaranteed, the drilling quality is high, and the operation is more convenient and safe.
