Description

Technical Field

[0001] The present invention belongs to the technical field of underground anchor support equipment, and in particular relates to a fully electric anchor drilling rig. Background Art

[0002] With the continuous improvement of the intelligence level of coal mines and the continuous promotion of technologies such as intelligent rapid excavation, the speed of mine excavation has been greatly improved, and the level of intelligent excavation has also been greatly improved. As one of the construction processes that consumes the longest man-hours in the excavation process, bolt support construction has reduced the impact of bolt support construction on the efficiency of tunnel excavation to a certain extent by adopting a large number of bolt drills in parallel and some bolts lagging support. However, with the use of a large number of bolt drills and the implementation of policy requirements such as "thousand-person mines" that have been implemented in coal mines for many years, the contradiction between the small number of people and the large number of equipment to be operated has been highlighted. Some coal mine underground excavation teams have repeatedly encountered the problem of a large number of equipment and a serious shortage of operators.

[0003] Anchor drilling rigs are the most widely used equipment in a complete set of rapid excavation equipment. In some rapid excavation equipment, in a single system, the number of anchor drilling rigs can reach more than 12. Generally, due to the limitation of work stations, some drilling rigs can be operated by one person at two times, but most drilling rigs can only be operated by one person at one time, resulting in a large number of people required for anchor operation, and the labor intensity of some people operating two drilling rigs at the same time is too high.

[0004] In addition, the existing anchor drills for coal mines are mainly divided into two categories: pneumatic and hydraulic. Pneumatic anchor drills are mainly single-body anchor drills, which have the advantages of light weight, convenient and flexible movement, but because of the slow construction speed, they are obsolete models in fast tunneling tunnels, and are only used in individual mines to supplement the anchors in individual positions. Hydraulic anchor drills are the mainstream anchor drill models currently installed on complete equipment such as tunneling machines and anchor boring machines. Generally, the whole machine adopts full hydraulic action, and some models have added functions such as electro-hydraulic control, which can reduce the labor intensity of workers to a certain extent. However, due to the characteristics that various parameters in hydraulic transmission are not easy to accurately measure and control, it is difficult for hydraulic anchor drills to improve their control level. Even if the anchor drill with an electro-hydraulic control system is added, it is basically mainly operated manually and frequently underground, and it is difficult to automatically control and realize the automation of anchor construction.

[0061] It should be noted that one side of the first electric slide 2 in the present disclosure is connected to the anchor drilling rig, and the other side is a mounting flange for connecting to the complete equipment on which the anchor drilling rig is installed, so that the remaining mechanisms of the anchor drilling rig except the first electric slide 2 can be lifted and lowered along the drilling direction. The sliding seat of the first electric slide 2 in the present disclosure is fixedly connected to the sliding mounting seat on the frame 1, and the slide grooves on both sides of the first electric slide 2 are slidably connected to a set of sliding guide rails at the rear of the frame 1, and then under the action of the first electric slide 2, the frame 1 performs a sliding motion parallel to the drilling direction.

[0062] The connection structure between the second electric slide 3 and the drill box assembly 4 is similar to the connection structure between the first electric slide 2 and the frame 1, and will not be described in detail in the present disclosure.

[0063] like Figure 3As shown, as an optional embodiment, the drill box assembly 4 includes a drive motor 4.1, a reducer 4.2 and a drill sleeve 4.3; the drive motor 4.1 drives the drill sleeve 4.3 to rotate through the reducer 4.2, and the drill sleeve 4.3 is provided with a threaded hole that matches the thread of the drill rod or anchor rod. Specifically, the drive motor 4.1 adopts a high-speed electric motor and is fixedly installed with the reducer 4.2. At the same time, the drive motor 4.1 can output the specified torque and speed under the control of the electronic control system 8, and feed back the output value to the electronic control system 8 in real time.

Specifically, the drill rod can be stored on the right side of the frame 1, and the working position of the drill rod can be located in front of the frame 1. At the same time, the rotating motor 5.3 is a structure in which the motor shaft is hollow, and can output a specified angle as required under the control of the motor control system.

[0065] like Figure 5As shown, as an optional embodiment, the clamping assembly 5.6 includes a clamping seat 5.6.2, two clamping heads 5.6.1, two electromagnets 5.6.6 and two reset springs 5.6.5. The clamping seat 5.6.2 is fixedly connected to the rotating seat 5.5, and includes two clamping arms arranged opposite to each other; the two clamping heads 5.6.1 are respectively slidably arranged on the opposite side walls of the two clamping arms; the two electromagnets 5.6.6 are respectively arranged in the two clamping arms, and are used to drive the two clamping heads 5.6.1 to move toward or away from each other; one end of the reset spring 5.6.5 is connected to the clamping head 5.6.1, and the other end is connected to the clamping seat 5.6.2, and is used to make the clamping head 5.6.1 return to the initial position, wherein the material of the clamping head 5.6.1 is magnetically conductive steel. By such arrangement, when the electromagnet 5.6.6 is energized, it can slide on the clamping arm, i.e. retract, thereby releasing the drill rod. When the power is off, the clamping head 5.6.1 can be reset in time under the action of the reset spring 5.6.5, that is, the clamping assembly 5.6 in the present disclosure can also be controlled by the electronic control system 8.

[0066] As an optional embodiment, the clamping end of the clamping head 5.6.1 is hemispherical, so that the drill rod can be clamped better.

[0067] As an optional embodiment, the sliding end of the clamping head 5.6.1 is cylindrical, and the clamping head 5.6.1 is provided with an annular groove located at the sliding end; the clamping assembly 5.6 also includes a sealing ring 5.6.7; the sealing ring 5.6.7 is located in the annular groove to seal the gap between the clamping head 5.6.1 and the clamping seat 5.6.2.

[0068] As an optional implementation, the structure of the second picking and placing device 6 is the same as that of the first picking and placing device 5 , and the second picking and placing device 6 and the first picking and placing device 5 are symmetrically arranged.

[0069] like Figure 6 As shown, as an optional embodiment, the top plate assembly 7 includes a fixed plate 7.3, a plurality of guide posts 7.4, a top plate 7.1, a plurality of top cones and a plurality of spring members 7.2. The fixed plate 7.3 is arranged at the top of the frame 1; a plurality of guide posts 7.4 are slidably connected to the fixed plate 7.3 so that the fixed plate 7.3 can slide along the guide posts 7.4; the top plate 7.1 is fixedly connected to the plurality of guide posts 7.4; a plurality of top cones are arranged on the upper surface of the top plate 7.1; a plurality of spring members 7.2 are respectively sleeved on the plurality of guide posts 7.4, and the two ends of the spring members 7.2 are respectively abutted against the fixed plate 7.3 and the top plate 7.1; and the force sensor 7.5 is abutted between the fixed plate 7.3 and the frame 1. The force sensor 7.5 has a high sampling frequency, and when working, it can collect the magnitude of the positive pressure acting on the force sensor 7.5 in real time.

[0070] The electric control system 8 is composed of an electric control box, control program software, etc., and is used for automatic program control during anchor bolt installation.

[0071] When not in operation, all mechanisms of the anchor bolt of the drilling rig are in a retracted state, wherein the drill box assembly 4 is located at the bottom end of the anchor bolt drilling rig, and the first pick-and-place device 5 and the second pick-and-place device 6 are both retracted and located at both sides of the drilling rig.

[0072] During work, install the drill rod and anchor rod on the anchor drilling rig and start the drilling rig. The steps are as follows:

[0073] Step 1: The electronic control system 8 controls the first electric slide 2 to realize the ascent of the frame 1 until the top plate assembly 7 is plugged and fixed into the tunnel; wherein, the force sensor 7.5 measures the contact force with the top plate 7.1 in real time, feeds back to the electronic control system 8, and adjusts the electric slide of the drilling rig lifting device to ensure that the top contact force is at a preset value.

[0074] Step 2: The electric control system 8 controls the first pick-and-place device 5 to grab the drill rod and move the drill rod to the working position; specifically, the electric control system 8 controls the rotation of the rotating seat 5.5 through the rotating motor 5.3 and controls the clamping assembly 5.6 to grab the drill rod and move the drill rod to the working position;

[0075] Step 3: The electric control system 8 controls the drill box assembly 4 to rise through the second electric slide 3 to achieve the connection between the drill box assembly 4 and the drill rod; and when the drill box assembly 4 is connected to the drill rod, the electric control system 8 controls the first pick-up and placement device 5 to release the drill rod; specifically, the electric control system 8 controls the drive motor 4.1 to achieve the slow rotation of the drill sleeve 4.3, so as to achieve its connection with the drill rod; and when the electric control system 8 no longer supplies power to the clamping assembly 5.6, the clamping head 5.6.1 retracts to release the drill rod, and the electric control system 8 controls the rotating seat 5.5 to rotate through the rotating motor 5.3 so that the first pick-up and placement device 5 is retracted to the right side of the frame 1;

[0076] Step 4: The electric control system 8 continues to control the rise of the drill box assembly 4 through the second electric slide 3, and controls the drilling of the drill rod through the drill box assembly 4 until the drilling operation is completed; specifically, the second electric slide 3 pushes the drill rod to move upward, and at the same time drives the motor 4.1 to keep the drill rod rotating; the electric control xit monitors the output torque of the motor of the drill box assembly 4, the longitudinal position of the drill box assembly 4 on the drilling rig, and the thrust value of pushing the drill box upward in real time; records the drill box longitudinal position parameters when the output torque of the drill box motor and the thrust value of the drill box upward movement begin to increase significantly; thereby enabling the electric control system 8 to adjust the control parameters of the drill box motor to drive the drill box to reach a preset stable speed; monitors the output torque of the drill box motor, the thrust value of the drill box upward movement, and the speed of the drill box upward movement, and automatically adjusts the control parameters of the drill box feeding device to ensure that the drill box motor can output at full power when the speed of the drill box upward movement does not exceed the preset value;

[0077] Step 5: The electric control system 8 controls the drill box assembly 4 to descend through the second electric slide 3 so that the drill rod exits the borehole; the first pick-and-place device 5 grabs the drill rod and moves the drill rod to its initial position, wherein when the first pick-and-place device 5 grabs the drill rod, the electric control system 8 controls the drill box assembly 4 to disconnect it from the drill rod; specifically, the electric control system 8 supplies power to the electromagnet 5.6.6 to retract the clamping head 5.6.1. Then the electric control system 8 controls the first pick-and-place device 5 to move to the working position. The electric control system 8 controls the drill box assembly 4 to continue to descend through the second electric slide 3 until the drill rod descends to the initial position, stops supplying power to the electromagnet 5.6.6 of the first pick-and-place device 5, and extends the clamping head 5.6.1 to grab the drill rod, and then the electric control system 8 controls the first pick-and-place device 5 to move to the right side of the frame 1;

[0078] Step 6, the electric control system 8 controls the second pick-and-place device 6 to grab the anchor rod and move the anchor rod to the working position;

[0079] Step 7: The electric control system 8 controls the drilling box assembly 4 to rise through the second electric slide 3 to achieve the connection between the drilling box assembly 4 and the anchor rod; and when the drilling box assembly 4 is connected to the anchor rod, the electric control system 8 controls the second pick-up and placement device 6 to release the anchor rod;

[0080] Step 8: The electric control system 8 continues to control the drilling box assembly 4 to rise through the second electric slide 3 to push the anchor rod into the drill hole until the anchor rod reaches the designated position;

[0081] Step 9: The electric control system 8 tightens the anchor nut through the drill box assembly 4 to achieve the installation of the anchor.

[0082] It should be noted that steps 6, 7, 8 and 9 of the anchor drilling rig driving the anchor installation are the same as the steps of driving the drill rod to drill a hole, except that the anchor itself does not rotate, and will not be described in detail here.

[0083] In summary, the anchor drilling rig disclosed in the present invention has the following technical effects: the output torque, thrust, speed, etc. of the second electric slide 3 drilling rig lifting device, etc. can be monitored in real time, and the working state of the drilling rig can be controlled according to the real-time monitoring data, so that the drilling rig can always run efficiently and ensure a high anchor construction speed;

[0084] The clamping heads 5.6.1 of the first pick-and-place device 5 and the second pick-and-place device 6 both adopt a clamping method of retraction controlled by an electromagnet 5.6.6 and reset by a spring, which can effectively adjust the clamping state according to the working state, has a good holding effect on the clamping state, and can release it in time.

[0085] The top plate assembly 7 integrates a force sensor 7.5, which can monitor the top force of the drilling rig in real time. At the same time, in cooperation with the first electric slide 2, the lifting state of the drilling rig can be adjusted in time to maintain a relatively stable top force, making the drilling process more stable.

[0086] The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure.
