Description

Technical Field

[0001] This disclosure belongs to the technical field of downhole anchor bolt support equipment, specifically relating to a construction operation method based on a fully electric anchor bolt drilling rig. Background Technology

[0002] With the continuous improvement of coal mine intelligence and the widespread adoption of technologies such as intelligent rapid tunneling, mine tunneling speed and intelligence levels have significantly increased. As one of the most time-consuming construction procedures in tunneling, anchor bolt support construction has, to some extent, reduced its impact on tunneling efficiency by employing a large number of anchor bolt drilling rigs operating in parallel and using delayed anchor bolt support in some cases. However, the extensive use of anchor bolt drilling rigs and the implementation of policies such as the "1,000-person mine" policy in coal mines, which have been in place for many years, have highlighted the contradiction between the limited number of personnel and the large amount of equipment required for operation. This has led to frequent problems in some coal mine tunneling teams where there is a large amount of equipment but a severe shortage of operators.

[0003] As the most frequently used equipment in rapid tunneling systems, anchor bolt drilling rigs are used in the largest number of units in some rapid tunneling systems. In some rapid tunneling systems, the number of anchor bolt drilling rigs can reach more than 12 units. Generally, due to work position limitations, some drilling rigs can be operated by one person to operate two rigs, but most drilling rigs can only be operated by one person to operate one rig. This results in a large number of personnel required for anchor bolt operation, and the labor intensity of some personnel who operate two drilling rigs at the same time is too high.

[0004] Furthermore, existing anchor bolt drilling rigs used in coal mines are mainly divided into two categories: pneumatic and hydraulic. Pneumatic anchor bolt drilling rigs are mainly single-unit anchor bolt drilling rigs, which have the advantages of being lightweight and easy to move and be flexible. However, due to their slow construction speed, they are obsolete in fast-moving tunnels and are only used in a few mines for supplementary anchor bolting in specific locations. Hydraulic anchor bolt drilling rigs are the mainstream anchor bolt drilling rig model currently installed on tunneling machines, roadheader-anchoring machines, and other complete sets of equipment. Generally, the entire machine adopts a fully hydraulic operation, and some models have added electro-hydraulic control functions, which can reduce the labor intensity of workers to a certain extent. However, due to the difficulty in accurately measuring and controlling various parameters in hydraulic transmission, it is difficult to improve the control level of hydraulic anchor bolt drilling rigs. Even anchor bolt drilling rigs with electro-hydraulic control systems still rely mainly on frequent manual operation underground, making it difficult to automate anchor bolt construction through automatic control.

[0060] like Figure 1 and Figure 2As shown, this disclosure provides a construction operation method based on a fully electric anchor bolt drilling rig. The fully automatic anchor bolt drilling rig is used to automatically complete drill rod drilling and anchor bolt installation in roadways. The fully electric anchor bolt drilling rig includes a first electric slide 2, a frame 1, a second electric slide 3, a drill box assembly 4, a first pick-and-place device 5, a second pick-and-place device 6, a roof plate assembly 7, and an electrical control system 8. The frame 1 is mounted on the first electric slide 2; the frame 1 is the load-bearing component of the anchor bolt drilling rig, made of steel plate, and has a frame structure, consisting of a bottom plate, side plates, and a top plate. Guide rails are machined on one side of each side plate. One guide rail is used to connect to the first electric slide 2, and the other guide rail is used to connect to the second electric slide 3. The second electric slide 3 is mounted on the lower part of the frame 1. The drill box assembly 4 is mounted on the second electric slide 3 and is used to drive the drill rod to drill; the first pick-and-place device 5 is mounted on the upper part of the frame 1 and is used to pick up and release the drill rod; the second pick-and-place device 6 is mounted on the upper part of the frame 1 and is arranged opposite to the first pick-and-place device 5, and is used to pick up and release the anchor rod; the top plate assembly 7 is mounted on the top of the frame 1 and is used to fix the fully electric anchor bolt drilling machine during operation; the electrical control system 8 is used to control the first electric slide 2, the second electric slide 3, the drill box assembly 4, the first pick-and-place device 5, and the second pick-and-place device 6; the anchor bolt drilling machine in this disclosure adopts fully electric control and operation, can automatically adjust the drilling machine working parameters according to the working status, and can store the drill rod and an anchor rod with a built-in explosive cartridge, and can realize one-button automatic construction to complete the anchor bolt drilling and anchor bolt installation.

[0061] It should be noted that the first electric slide 2 in this disclosure is connected to the anchor drilling rig on one side and has a mounting flange on the other side for connecting to the entire machine of the anchor drilling rig, thereby enabling the other mechanisms of the anchor drilling rig, except for the first electric slide 2, to move up and down along the drilling direction. The sliding seat of the first electric slide 2 is fixedly connected to the sliding mounting seat on the frame 1, and the sliding 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. Therefore, under the action of the first electric slide 2, the frame 1 performs a sliding movement 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 this disclosure.

[0063] like Figure 3As shown, in one 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 via the reducer 4.2. The drill sleeve 4.3 has a threaded hole that mates with the drill rod or anchor rod. Specifically, the drive motor 4.1 is a high-speed motor, fixedly mounted to the reducer 4.2. Under the control of the electronic control system 8, the drive motor 4.1 can output a specified torque and speed, and feed back the output value to the electronic control system 8 in real time. The reducer 4.2 is a two-stage planetary reducer, and the output shaft of the drill sleeve 4.3 assembly is connected to the output shaft of the reducer 4.2. The reducer 4.2 housing is fixedly connected to the drill box mounting base and can move along the drilling rig guide rail under the drive of the drill box mounting base.

[0064] like Figure 4 As shown, in one optional embodiment, the first pick-and-place device 5 includes a fixed base 5.1, a connecting pin, a rotary motor 5.3, a rotating seat 5.5, and a clamping assembly 5.6. The fixed base 5.1 is mounted on the right side of the frame 1; the rotary motor 5.3 is fixedly mounted on the fixed base 5.1; the rotating seat 5.5 is rotatably mounted on the frame 1 via a connecting pin 5.4; the rotating seat 5.5 is connected to the output shaft of the first rotary motor 5.3; the clamping assembly 5.6 is disposed on the rotating seat 5.5 and is used to clamp or release the drill rod; wherein, the fixed base 5.1 extends forward so that the output shaft of the rotary motor 5.3 is located at the right front of the frame 1. This arrangement allows the rotating seat 5.5 to have a relatively large rotation angle, thereby making the overall space arrangement of the frame 1 more reasonable and reducing its volume. Specifically, the drill rod can be stored on the right side of the frame 1, while the working position of the drill rod can be located at the front of the frame 1. Meanwhile, the rotary motor 5.3 has a hollow motor shaft structure and can output a specified angle as required under the control of the motor control system.

[0065] like Figure 5As shown, in one optional embodiment, the clamping assembly 5.6 includes a clamping base 5.6.2, two clamping heads 5.6.1, two electromagnets 5.6.6, and two return springs 5.6.5. The clamping base 5.6.2 is fixedly connected to the rotating base 5.5 and includes two clamping arms arranged opposite each other; the two clamping heads 5.6.1 are slidably disposed on the opposite sidewalls of the two clamping arms; the two electromagnets 5.6.6 are respectively disposed in the two clamping arms and are used to drive the two clamping heads 5.6.1 to move towards or away from each other; one end of the return spring 5.6.5 is connected to the clamping head 5.6.1, and the other end is connected to the clamping base 5.6.2, for returning the clamping head 5.6.1 to the initial position, wherein the clamping head 5.6.1 is made of steel with magnetic conductivity. With this configuration, when the electromagnet 5.6.6 is energized, it can slide and retract on the clamping arm, 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 return spring 5.6.5. That is, the clamping component 5.6 in this disclosure can also be controlled by the electronic control system 8.

[0066] As an optional implementation, the clamping end of the clamping head 5.6.1 is hemispherical. This design allows for better clamping of the drill pipe.

[0067] As an optional implementation, 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 pick-and-place device 6 is the same as that of the first pick-and-place device 5, and the second pick-and-place device 6 and the first pick-and-place device 5 are arranged symmetrically.

[0069] like Figure 6 As shown, in one 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 disposed at the top of the frame 1; the plurality of guide posts 7.4 are slidably connected to the fixed plate 7.3, allowing the fixed plate 7.3 to slide along the guide posts 7.4; the top plate 7.1 is fixedly connected to the plurality of guide posts 7.4; the plurality of top cones are disposed on the upper surface of the top plate 7.1; the 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 abut against the fixed plate 7.3 and the top plate 7.1 respectively; a 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 during operation, it can collect the magnitude of the normal force acting on the force sensor 7.5 in real time.

[0070] The electrical control system 8 consists of an electrical 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 drilling rig's anchor bolts are in the retracted state. The drill box assembly 4 is located at the bottom 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 on both sides of the drilling rig.

[0072] During operation, drill rods and anchor rods are installed on the anchor drilling rig, and the drilling rig is started. The operation steps are as follows:

[0073] Step 1: The electrical control system 8 controls the first electric slide 2 to raise the frame 1 until the top plate assembly 7 is inserted and fixed with the roadway; wherein, the force sensor 7.5 measures the contact force with the top plate 7.1 in real time, feeds it back to the electrical control system 8, and adjusts the electric slide of the drilling rig lifting device to ensure that the contact force is within the preset value.

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

[0075] Step 3: The electrical control system 8 controls the drill box assembly 4 to rise via the second electric slide 3 to connect the drill box assembly 4 with the drill rod; and when the drill box assembly 4 is connected to the drill rod, the electrical control system 8 controls the first pick-and-place device 5 to release the drill rod; specifically, the electrical control system 8 controls the drive motor 4.1 to slowly rotate the drill sleeve 4.3, thereby connecting it with the drill rod; and when the electrical 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 electrical control system 8 controls the rotating seat 5.5 to rotate via the rotary motor 5.3 so that the first pick-and-place device 5 retracts to the right side of the frame 1;

[0076] Step 4: The electronic control system 8 continues to control the drill box assembly 4 to rise via the second electric slide 3, and controls the drill rod to move via the drill box assembly 4, until the drilling operation is completed. Specifically, the second electric slide 3 pushes the drill rod upward, while the drive motor 4.1 keeps the drill rod rotating. The electronic control system 8 monitors in real time the output torque of the drill box assembly 4 motor, the longitudinal position of the drill box assembly 4 on the drilling rig, and the magnitude of the thrust value that pushes the drill box upward. It records the longitudinal position parameters of the drill box when the output torque of the drill box motor and the upward thrust value of the drill box begin to increase significantly. This allows the electronic control system 8 to adjust the control parameters of the drill box motor to drive the drill box to a preset stable speed. It monitors the output torque of the drill box motor, the upward thrust value of the drill box, and the upward speed of the drill box, and automatically adjusts the control parameters of the drill box feed device to ensure that the drill box motor can output full power when the upward speed of the drill box does not exceed the preset value.

[0077] Step 5: The electrical control system 8 controls the drill box assembly 4 to descend via the second electric slide 3, causing the drill rod to exit the borehole; the first pick-and-place device 5 grabs the drill rod and moves it to its initial position. While the first pick-and-place device 5 is grabbing the drill rod, the electrical control system 8 controls the drill box assembly 4 to disconnect from the drill rod. Specifically, the electrical control system 8 supplies power to the electromagnet 5.6.6, causing the clamping head 5.6.1 to retract. Then, the electrical control system 8 controls the first pick-and-place device 5 to move to the working position. The electrical control system 8 controls the drill box assembly 4 to continue descending via the second electric slide 3 until the drill rod reaches its initial position. Power supply to the electromagnet 5.6.6 of the first pick-and-place device 5 is stopped, causing the clamping head 5.6.1 to extend and grab the drill rod. Then, the electrical 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 electronic control system 8 controls the second pick-and-place device 6 to grab the anchor bolt and move it to the working position;

[0079] Step 7: The electrical control system 8 controls the drill box assembly 4 to rise through the second electric slide 3 to connect the drill box assembly 4 with the anchor rod; and when the drill box assembly 4 is connected to the anchor rod, the electrical control system 8 controls the second pick-and-place device 6 to release the anchor rod.

[0080] Step 8: The electrical control system 8 continues to control the drill box assembly 4 to rise via the second electric slide 3, so as to push the anchor rod into the borehole until the anchor rod is deep enough to reach the designated position;

[0081] Step 9: The electrical control system 8 tightens the anchor bolt nut through the drill box assembly 4 to install the anchor bolt.

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

[0083] In summary, the anchor drilling rig disclosed herein has the following technical effects: the output torque, thrust, speed, etc. of the second electric slide table 3 drilling rig lifting device can be monitored in real time, and the working status of the drilling rig can be controlled according to the real-time monitoring data, so as to achieve high-efficiency operation of the drilling rig at all times and ensure a high anchor drilling 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 spring reset, which can effectively adjust the clamping state according to the working state, maintain the clamping state well, and release it in time.

[0085] The top plate assembly 7 integrates a force sensor 7.5, which can monitor the jacking force of the drilling rig in real time. At the same time, in conjunction with the first electric slide 2, it can adjust the lifting status of the drilling rig in a timely manner to maintain a relatively stable jacking force, making the drilling process more stable.

[0086] The above are merely preferred embodiments of this disclosure and are not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
