Description

Technical Field

[0001] This utility model relates to the field of mining machinery engineering technology, specifically a quick anchor changing positioning and locking device for coal mine anchor machines. Background Technology

[0002] Currently, coal mine tunneling and anchoring operations mostly utilize integrated tunneling and anchoring machines, which combine tunneling and anchoring functions, enabling parallel operations of both. However, in practical applications, existing tunneling and anchoring machines have the following problems in the anchor replacement process: The replacement of anchor bolts in traditional roadheader-anchor-jacking machines usually requires manual intervention. Operators need to install new anchor bolts. During actual operation, the vibration and impact loads generated by the tunneling equipment make the anchor bolts prone to falling off. Traditional anchor bolt locking methods mainly rely on threaded connections and mechanical nuts. This method is cumbersome and inefficient for manual disassembly. There is a lack of existing technology that can provide reliable locking while ensuring rapid replacement, resulting in low anchor bolt replacement efficiency and seriously affecting tunneling speed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1-4 As shown, this utility model provides a technical solution: a quick anchor changing positioning and locking device for a coal mine anchoring machine, including an anchoring boom frame 1, a front side seat 101 fixedly welded to the front wall of the anchoring boom frame 1, and a rear side seat 102 fixedly welded to the rear wall of the anchoring boom frame 1. A set of fixing seats 205 is fixedly welded to the upper and lower walls of the front seat 101, and a set of fixing seats 205 is also welded to the upper and lower walls of the rear seat 102. The four sets of fixing seats 205 have through slots, and a set of sliding shafts 206 is fixedly inserted into two sets of fixing seats 205 at the same horizontal line. The front seat 101 has through slots, and a protective tube 212 is fixedly installed in the slots. An anchor rod 213 is installed inside the protective tube 212. A connecting seat 214 is installed at the right end of the anchor rod 213. A limiting chamber 3 is fixedly sleeved on the outside of the connecting seat 214. A retaining ring groove 301 is opened on the right outer wall of the anchor rod 213. Two sets of extrusion blocks 302 are installed inside the retaining ring groove 301. A set of electric push rods 303 is connected to one side of each of the two sets of extrusion blocks 302. The two sets of electric push rods 303 are fixedly installed inside the limiting chamber 3.

[0017] Based on the overall structure of the device, an innovative structure is adopted to enable rapid replacement and reliable locking of anchor bolts 213, significantly reducing manual intervention and downtime, and effectively improving work efficiency; at the same time, it can resist vibration and impact loads generated during tunneling, reducing the problem of anchor bolts 213 easily falling off.

[0018] like Figure 1As shown, a set of cylinders 2 are fixedly installed at the upper and lower ends of the tunneling boom frame 1, respectively. A set of piston rods 201 are connected to the left ends of the two sets of cylinders 2. The left ends of the two sets of piston rods 201 are fixedly connected to the top plate 203 through the inside of the support block 202. The support block 202 is fixedly welded to the upper wall of the tunneling boom frame 1. The inside of the support block 202 is provided with a slot that matches the outer diameter of the piston rod 201. The two sets of cylinders 2 are synchronously controlled by connecting the circuit.

[0019] By fixing the cylinder 2 and piston rod 201 to both sides of the piston rod 201 and using wiring to control the two sets of cylinders 2, it is possible to ensure that the cylinder 2 and piston rod 201 are synchronized.

[0020] like Figure 1 As shown, a set of slots are provided on the left wall of the top plate 203. The inner diameter of the slots is adapted to the outer diameter of the protective tube 212. Two sets of contact blocks 204 are fixedly welded to the left wall of the top plate 203. Sensors are installed on the surface of the top plate 203.

[0021] By installing two sets of wall-contacting blocks 204 on the surface of the top plate 203, it can make contact with the wall first, and a sensor is installed to detect whether it is in contact with the wall.

[0022] like Figure 2 As shown, the surface material of the sliding shaft 206 is chrome-plated carbon steel. A set of sliding seats 207 is respectively fitted on the outside of the two sets of sliding shafts 206, and the two sets of sliding seats 207 are fixedly connected by a connecting plate 208.

[0023] By designing the surface of the sliding shaft 206 as chrome-plated carbon steel, it is possible to ensure smoothness and low friction while increasing corrosion resistance.

[0024] like Figure 1 As shown, a threaded groove is provided through the interior of the rear seat 102, and a lead screw 209 is inserted into the threaded groove. A linear stepper motor 210 is installed on the left end of the lead screw 209. The left end of the linear stepper motor 210 is fixedly connected to the hydraulic drill 211 through a connecting sleeve. The hydraulic drill 211 is fixedly connected to the surface wall of the connecting plate 208 by screws.

[0025] By using a linear stepper motor 210 to drive the lead screw 209 to rotate, a translational force is generated to move the entire device.

[0026] like Figure 4 As shown, the depth of the retaining ring groove 301 is consistent with the height of the extrusion block 302.

[0027] By opening a retaining ring groove 301 on the outer wall of the anchor rod 213, and opening the groove to a depth consistent with that of the compression block 302, the anchor rod 213 can be effectively limited by the compression block 302.

[0028] Working Principle: This device is part of a coal mine anchoring machine, used for quick anchor replacement and positioning locking of anchor bolts 213. When anchor replacement is required, the operator inserts the side of anchor bolt 213 without the retaining ring groove 301 through the inside of the protective tube 212, and then inserts the other side of anchor bolt 213 into the connecting seat 214, ensuring that the anchor bolt 213 contacts the inside of the connecting seat 214. Then, the electric push rod 303 is controlled to drive the pressing block 302 to extend forward. When the pressing block 302 extends forward, it will enter the retaining ring groove 301, ensuring that the two sets of pressing blocks 302 restrict the anchor bolt 213. Then, other subsequent work can be carried out. The linear stepper motor 210 drives the lead screw 209 to rotate. When the lead screw 209 rotates, it will intersect with the threaded groove opened inside the rear seat 102, thereby... The generated force drives the two sets of sliding seats 207 to move on the sliding shaft 206. At the same time, the cylinder 2 drives the piston rod 201 to move forward. When the contact block 204 on the top plate 203 and the sensor contact the wall, the piston rod stops. The distance between the piston rod and the wall is measured by the surveying equipment on the anchor excavator and transmitted to the overall controller. The linear stepper motor 210 determines the distance to move to the left based on this distance. At the same time, the electric push rod 303 is controlled to retract inward, and the pressing block 302 moves outward from the retaining ring groove 301, removing the restriction on the anchor rod 213. Then, the hydraulic drill 211 presses the anchor rod 213 to the left, inserting the anchor rod 213 into the pre-drilled hole. This process is repeated, with each new anchor rod 213 pressing against the previous one until it touches the bottom of the hole, after which other work is carried out.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
