Description

Technical Field

[0001] This utility model relates to the field of transmission connection technology, specifically to a side-protected gear transmission connection mechanism for a paste filling hydraulic support. Background Technology

[0002] Paste-filled hydraulic supports are indispensable support equipment in backfilling mining operations. They are mainly used in coal mines and other mining processes, especially in situations where coal is under pressure from three sources (buildings, railways, and water bodies). Through paste-filling technology, green mining and environmental protection can be achieved in the mining area.

[0003] Among the existing patent documents, there is a patent with publication number CN 118442098 A entitled "Split connection structure of split paste filling hydraulic support". This patent mainly adjusts the spacing through the meshing transmission of gears and racks. Since the connection structure is located on both sides of the base and has no protective measures, when it is working underground, falling rocks can easily affect the rolling of the gears, and in severe cases, it can cause the gears to deform or be damaged. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a side-protected gear transmission connection mechanism for a hydraulic support for paste filling. This mechanism can effectively prevent falling rocks from rolling into the tooth groove through the side protective shell and anti-collision steel wire, thus avoiding the interruption of transmission due to the obstruction of falling rocks when the transmission gear is rolling. The anti-collision steel wire, because it is set on the outside, can first block and buffer larger falling rocks, effectively preventing the side protective shell from being directly impacted and causing large-area deformation, which greatly extends the service life of the side protective shell.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is implemented as follows:

[0006] A side-protection type toothed rail transmission connection mechanism for a paste-filling hydraulic support includes a fixed rail frame and a sliding toothed frame; the fixed rail frame is applied to the bottom side of the mine hydraulic support part in the paste-filling hydraulic support, and the sliding toothed frame is applied to the bottom side of the paste-filling isolation part in the paste-filling hydraulic support; the side-protection type toothed rail transmission connection mechanism of this paste-filling hydraulic support is mainly used to adjust the distance between the mine hydraulic support part and the paste-filling isolation part.

[0007] The fixed rail frame has multiple linearly distributed toothed grooves. A transmission gear is rotatably mounted on one end of the sliding toothed frame, and the teeth on the transmission gear are always meshed in the toothed grooves. The fixed rail frame is equipped with a drive mechanism that drives the transmission gear to rotate. Under the drive of the drive mechanism, the transmission gear can roll linearly along the toothed grooves.

[0008] The fixed rail frame is equipped with a side protective shell that can completely cover the tooth groove and transmission gear. The side protective shell is an L-shaped one-piece die-cast metal shell.

[0009] Multiple anti-collision steel wires are also installed on the outer side of the side protective shell, with both ends of the anti-collision steel wires passing through cable trays located on both sides of the side protective shell. A fastening mechanism is installed on the outer side of the cable trays to straighten and tighten the anti-collision steel wires. After the anti-collision steel wires are straightened and tightened, the distance between them and the surface of the side protective shell is 10-15mm.

[0010] By adopting the above solution, the mechanism can effectively prevent falling rocks from rolling into the tooth groove through the side protective shell and anti-collision steel wire, thus avoiding the interruption of transmission due to the obstruction of falling rocks when the transmission gear is rolling. The anti-collision steel wire, because it is set on the outside, can first block and buffer larger falling rocks, effectively preventing the side protective shell from being directly impacted and causing large-area deformation, which greatly extends the service life of the side protective shell.

[0011] In a preferred embodiment of a side-protection gear transmission connection mechanism for a paste-filling hydraulic support, a locking mechanism is fixedly installed on a screw tube on the outside of a cable tray. A locking sleeve is threaded onto the outside of the screw tube. The anti-collision steel wire is sequentially threaded through the screw tube and the locking sleeve. Finally, a limiting steel ball is threaded through the anti-collision steel wire near its end. The limiting steel ball abuts against the end of the locking sleeve, and the diameter of the limiting steel ball is larger than the inner diameter of the locking sleeve. The anti-collision steel wire is knotted at its end to form a limiting knot, which abuts against the limiting steel ball. The limiting knot is further welded and fixed by welding.

[0012] The above solution is adopted to facilitate the tightening of the anti-collision steel wire during subsequent use. Because the anti-collision steel wire may loosen after being hit by falling rocks for a long time, once the anti-collision steel wire becomes loose, the locking nut can be rotated and moved outward to resist the limiting steel ball and pull the anti-collision steel wire outward, thus restoring the tension of the anti-collision steel wire.

[0013] In a preferred embodiment of a side-protection gear-rail transmission connection mechanism for a hydraulic support for paste filling, the drive mechanism includes a positioning seat fixed on a sliding gear frame and located away from the end where the transmission gear is located. A motor is mounted on the positioning seat, and a drive gear is concentrically connected to the motor shaft. A driven gear is also concentrically connected to the transmission gear, and the drive gear and the driven gear are transmitted through gear chain meshing.

[0014] Using the above scheme, in order to achieve the rotation of the transmission gear, the motor drives the drive gear to rotate, and the driven gear rotates under the meshing transmission of the gear chain, which in turn drives the transmission gear to rotate. At this time, the teeth of the transmission gear continuously mesh with the tooth grooves, so that the sliding gear frame slides along the length direction of the fixed rail frame, thereby adjusting the distance between the mine hydraulic support part and the paste filling isolation part.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. This mechanism can effectively prevent falling rocks from rolling into the tooth groove through the side protective shell and anti-collision steel wire, thus avoiding the interruption of transmission due to the obstruction of falling rocks when the transmission gear is rolling. The anti-collision steel wire, because it is set on the outside, can first block and buffer larger falling rocks, effectively preventing the side protective shell from being directly impacted and causing large-area deformation, which greatly extends the service life of the side protective shell.

[0017] 2. To facilitate tightening of the anti-collision steel wire during subsequent use, since the anti-collision steel wire may loosen after being hit by falling rocks for a long time, once the anti-collision steel wire becomes loose, the locking nut can be rotated and moved outward to counteract the limiting steel ball and pull the anti-collision steel wire outward, thus restoring the tension of the anti-collision steel wire.

[0018] 3. In order to achieve the rotation of the transmission gear, the motor drives the drive gear to rotate, which in turn drives the driven gear to rotate through the meshing of the gear chain. At this time, the teeth of the transmission gear continuously mesh with the tooth grooves, so that the sliding gear frame slides along the length of the fixed rail frame, thereby adjusting the distance between the hydraulic support part and the paste filling isolation part of the mine.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one main embodiment 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.

[0034] like Figures 1 to 12 As shown, a side-protection geared rail transmission connection mechanism for a paste-filling hydraulic support includes a fixed rail frame 1 and a sliding gear frame 2. The fixed rail frame 1 is applied to the bottom side of the mine hydraulic support part 17 in the paste-filling hydraulic support, and the sliding gear frame 2 is applied to the bottom side of the paste-filling isolation part 18 in the paste-filling hydraulic support. This side-protection geared rail transmission connection mechanism for the paste-filling hydraulic support is mainly used to adjust the distance between the mine hydraulic support part 17 and the paste-filling isolation part 18. The fixed rail frame 1 has multiple linearly arrayed toothed grooves 3, and a transmission gear 4 is rotatably mounted on one end of the sliding gear frame 2. The teeth on the transmission gear 4 are always meshed in the toothed grooves 3. A drive mechanism is installed on the fixed rail frame 1 to drive the transmission gear 4 to rotate. Under the drive of the drive mechanism, the transmission gear 4 can roll linearly along the tooth groove 3. A side protective shell 5 that can completely cover the tooth groove 3 and the transmission gear 4 is installed on the outside of the fixed rail frame 1 by screws. The side protective shell 5 is an L-shaped one-piece die-cast metal shell. Multiple anti-collision steel wires 6 are also installed on the outside of the side protective shell 5. The two ends of the anti-collision steel wires 6 are respectively threaded into the cable tie plates 7 located on both sides of the side protective shell 5. A fastening mechanism that can straighten and tighten the anti-collision steel wires 6 is installed on the outside of the cable tie plates 7. After the anti-collision steel wires 6 are straightened and tightened, the distance between them and the surface of the side protective shell 5 is 10-15mm. The mechanism effectively prevents falling rocks from rolling into the tooth groove 3 through the side protective shell 5 and the anti-collision steel wire 6, thus avoiding the interruption of transmission of the transmission gear 4 due to the obstruction of falling rocks when it is rolling. The anti-collision steel wire 6, being located on the outside, can first block and buffer larger falling rocks, effectively preventing the side protective shell 5 from being directly impacted and causing large-area deformation, which greatly extends the service life of the side protective shell 5.

[0035] like Figures 10 to 11 As shown, the fastening mechanism is welded and fixedly installed on the outside of the cable tray 7. The outside of the cable tray 8 is fitted with a fastening sleeve 9 by a thread. The anti-collision steel wire 6 is sequentially passed through the cable tray 8 and the fastening sleeve 9. Finally, a limiting steel ball 10 is passed through the anti-collision steel wire 6 near its end. The limiting steel ball 10 abuts against the end of the fastening sleeve 9. The diameter of the limiting steel ball 10 is larger than the inner diameter of the fastening sleeve 9. The anti-collision steel wire 6 is knotted at its end to form a limiting knot 11. The limiting knot 11 abuts against the limiting steel ball 10. The limiting knot 11 is further welded and fixed by welding. To facilitate tightening of the anti-collision steel wire 6 during subsequent use, since the anti-collision steel wire 6 may become loose after being hit by falling rocks for a long time, once the anti-collision steel wire 6 becomes loose, the locking sleeving 9 can be rotated and moved outward to resist the limiting steel ball 10 and pull the anti-collision steel wire 6 outward, thus restoring the tension of the anti-collision steel wire 6.

[0036] like Figures 6 to 7As shown, the drive mechanism includes a positioning seat 12 fixed to the sliding gear frame 2 by screws at the end away from the transmission gear 4. A motor 13 is mounted on the positioning seat 12, and a drive gear 14 is concentrically connected to the shaft of the motor 13. A driven gear 15 is also concentrically connected to the transmission gear 4. The drive gear 14 and the driven gear 15 are driven by a gear chain 16. In order to achieve the rotation of the transmission gear 4, the motor 13 drives the drive gear 14 to rotate, which in turn drives the driven gear 15 to rotate through the gear chain 16, thereby driving the transmission gear 4 to rotate. At this time, the teeth of the transmission gear 4 continuously mesh with the tooth grooves 3, so that the sliding gear frame 2 slides along the length of the fixed rail frame 1, thereby adjusting the distance between the mine hydraulic support part 17 and the paste filling isolation part 18.

[0037] The working principle of this utility model:

[0038] Before application, the fixed rail frame 1 is fixed to the bottom side of the mine hydraulic support part 17 in the paste filling hydraulic support with screws, and the sliding gear frame 2 is fixed to the bottom side of the paste filling isolation part 18 in the paste filling hydraulic support with screws, so as to adjust the distance between the mine hydraulic support part 17 and the paste filling isolation part 18.

[0039] When adjusting the spacing, the motor 13 drives the drive gear 14 to rotate, and the driven gear 15 rotates under the meshing transmission of the gear chain 16, which in turn drives the transmission gear 4 to rotate. At this time, the teeth of the transmission gear 4 continuously mesh with the tooth groove 3, so that the sliding gear frame 2 slides along the length direction of the fixed rail frame 1, thereby adjusting the spacing between the mine hydraulic support part 17 and the paste filling isolation part 18.

[0040] During the above-mentioned use, the side protective shell 5 and the anti-collision wire 6 can effectively prevent falling rocks from rolling into the tooth groove 3, avoiding the transmission gear 4 from being interrupted by falling rocks when rolling. The anti-collision wire 6, being located on the outside, can first block and buffer larger falling rocks, effectively preventing the side protective shell 5 from being directly impacted and causing large-area deformation, which greatly extends the service life of the side protective shell 5. Moreover, in order to facilitate the tightening of the anti-collision wire 6 during subsequent use, since the anti-collision wire 6 may loosen after being impacted by falling rocks for a long time, once the anti-collision wire 6 loosens, the locking sleeving 9 can be rotated and moved outward to resist the limiting steel ball 10 and pull the anti-collision wire 6 outward, thus restoring the tension of the anti-collision wire 6.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
