Description

Technical Field

[0001] This utility model belongs to the field of coal mining technology, and in particular relates to an anchor bolt fixed support mechanism for coal mining. Background Technology

[0002] According to the published patent CN219220463U, a support anchor bolt fixing structure for coal mine roadways includes an outer shell. The top of the outer shell is fixedly connected to a fixed edge, and an anchor bolt is inserted into the inner wall of the outer shell. By setting an opening and closing mechanism, the pin is pulled out of the first limiting hole, and the brake rod is pulled upward. The brake rod drives the movable ring to slide synchronously. The movable ring drives the top of the traction rod to slide synchronously. The bottom end of the traction rod drives the barb to rotate and extend out of the receiving groove. Then, the pin is inserted into the inside of the second limiting hole. Through the above design, the opening and closing of the barb is controlled, avoiding the formation of grooves on some barbs during the insertion into the soil, thereby preventing some barbs from losing their grip and improving the fixing efficiency. However, there are still the following shortcomings.

[0003] While the above-mentioned equipment can improve the overall fixing efficiency by relying on barbs during use, the angle at which the equipment applies support to the outside is relatively effective, resulting in relatively low stability after the equipment is fixed. It is difficult to ensure that the equipment will not easily shift, and the reliability is poor. Therefore, we propose an anchor bolt fixing support mechanism for coal mines. Utility Model Content

[0004] The purpose of this utility model is to provide an anchor bolt fixing support mechanism for coal mines. Through the support mechanism and locking mechanism, it solves the problem that although the overall fixing efficiency of the equipment can be improved by relying on the barb, the angle at which the equipment applies support to the outside is relatively effective, resulting in relatively low stability of the overall equipment after fixing, making it difficult to ensure that the equipment will not easily shift and resulting in poor reliability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a coal mine anchor bolt fixing support mechanism, including a fixing sleeve, a through groove on the inner wall of the fixing sleeve, a plurality of sliding grooves on the inner wall of the fixing sleeve, and a support mechanism provided on the inner wall of the fixing sleeve.

[0007] The support mechanism includes a worm gear, the outer wall of which is rotatably connected to the inner wall of a fixed sleeve. A knob is fixedly connected to the top outer wall of the worm gear. A transmission rod is rotatably connected to the inner wall of the fixed sleeve. A worm wheel is fixedly connected to the outer wall of the transmission rod, and the outer wall of the worm wheel meshes with the outer wall of the worm gear. A helical gear is fixedly connected to the outer wall of the transmission rod. A transmission disc is rotatably connected to the inner wall of the fixed sleeve. The inner wall of the transmission disc has several inclined grooves. A second helical gear is fixedly connected to the outer wall of the transmission disc, and the outer wall of the second helical gear meshes with the outer wall of the first helical gear. Support blocks are slidably connected to the inner walls of the several inclined grooves. A guide disc is fixedly connected to the inner wall of the fixed sleeve. The inner wall of the guide disc has several guide grooves, and the inner walls of the guide grooves are slidably connected to the outer walls of the support blocks.

[0008] Furthermore, the inner walls of several of the slides are provided with locking mechanisms, the locking mechanisms including several locking pins, the outer walls of the several locking pins being slidably connected to the inner walls of the slides.

[0009] Furthermore, a pull ring is fixedly connected to the outer wall of the locking pin, and a spring is fixedly connected to the outer wall of the locking pin.

[0010] Furthermore, the outer wall of the spring is fixedly connected to the inner wall of the fixed sleeve, and the outer wall of the locking pin is fixedly connected with several connecting strips.

[0011] Furthermore, a rack is fixedly connected to the outer wall of each of the connecting strips, and a rack groove is provided on the inner wall of the fixing sleeve.

[0012] Furthermore, the inner walls of several rack grooves are slidably connected to the outer walls of several racks, and several gears are rotatably connected to the inner wall of the fixed sleeve.

[0013] Furthermore, the outer wall of the gear meshes with the outer walls of several racks, and an anchor rod is slidably connected to the inner wall of the through groove.

[0014] Furthermore, the inner wall of the anchor rod is provided with a locking hole, and the inner wall of the locking hole is slidably connected to the outer wall of a plurality of locking pins.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting up support blocks, allows the bottom of the equipment to be buried in the soil. Simply turning the knob clockwise will cause the worm to rotate, which in turn will drive the worm wheel to rotate. The worm wheel will drive the transmission rod to rotate, which will drive the helical gear to rotate. The helical gear will drive the second helical gear to rotate, which will drive the transmission disc to rotate counterclockwise. The transmission disc will cause several support blocks to move away from each other, thus providing additional support to the equipment from multiple angles. This greatly improves the stability of the equipment after it is fixed, ensuring that the equipment will not easily shift and demonstrating excellent reliability.

[0017] 2. This utility model incorporates locking pins. During use, several locking pins are inserted into the lock holes to secure the anchor rod. To remove the anchor rod, the pull ring is pulled outwards. The pull ring moves the locking pins, which in turn move several connecting bars and compress the springs. Each connecting bar moves the rack, which in turn moves the gears. Each gear moves the rack at its other end, which in turn moves the connecting bar on the other side. This movement causes the locking pins on the other side to move. During this process, the locking pins move away from each other and disengage from the lock holes, thus no longer restricting the individual movement of the anchor rod. This allows for quick disassembly and installation of the anchor rod, saving on anchor rod replacement costs and effectively improving the versatility of the equipment.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

During use, several locking pins 301 will be inserted into the locking holes 30. Anchor rod 308 is fixed inside the 9-hole. If anchor rod 308 needs to be removed, pull ring 302 can be pulled outward. Pull ring 302 will drive locking pin 301. Locking pin 301 will drive several connecting bars 304 to move and squeeze spring 303 during this period. Several connecting bars 304 will drive rack 305 to move. Several racks 305 will drive gear 307 to rotate. Several gears 307 will drive the rack 305 at the other end to move. The rack 305 at the other end will drive the connecting bar 304 on the other side to move. Several connecting bars 304 will drive the locking pin 301 on the other side to move. During this period, several locking pins 301 will move away from each other and disengage from the locking hole 309 so as not to restrict the individual movement of anchor rod 308.
