技术领域Technical field
本发明涉及矿山机械领域技术领域,尤其涉及一种井下快速掘进的掘支锚一体机***及其使用方法。The invention relates to the technical field of the field of mining machinery, in particular to a digging-supporting-anchor integrated machine system for rapid underground excavation and a use method thereof.
背景技术Background technique
随着生产矿井采深的增加,地应力、围岩受力及变形复杂多样,锚网支护以其支护效果好、适用范围广、可以根据巷道条件灵活应变等特点,被广大巷道开采所使用,但在目前巷道掘进的过程中,机械化掘进效率很高,巷道支护速度远远滞后于掘进速度。掘支锚时间严重不匹配,导致掘进机进尺时间远小于工作总时间,大量的时间内掘进机停工作业用来进行支护作业。解决掘支锚时间严重不匹配的一个方向为实现掘支锚平行作业。With the increase of mining depth in production mines, the in-situ stress, surrounding rock stress and deformation are complex and diverse. Bolt-mesh support is widely used in roadway mining due to its good supporting effect, wide application range, and flexible strain according to roadway conditions. However, in the current process of roadway excavation, the efficiency of mechanized excavation is very high, and the speed of roadway support is far behind the excavation speed. There is a serious mismatch between the excavation and anchor time, which results in the roadheader's footage time being far less than the total working time, and a large amount of time the roadheader is out of work for supporting operations. One direction to solve the serious mismatch in the time of excavation and support is to realize the parallel operation of excavation and support.
CN104500086A中公开了专利名称为:一种巷道无人掘锚一体机。其支护***就只涉及临时支护与锚杆支护,不能解决小块围岩掉落的问题,如果需要加装锚网需要人工靠近工作断面,为了人员安全截割头需要停工,不能实现掘支锚平行作业,同时粉尘、噪音等因素也对工人存在极大的安全威胁。其截割部一次停车作业只能截割一次进给量,效率比较低。The patent name disclosed in CN104500086A is: an unmanned roadway digging and anchoring integrated machine. Its support system only involves temporary support and bolt support, and cannot solve the problem of small pieces of surrounding rock falling. If it is necessary to install an anchor net, it must be manually approached to the working section. The cutting head needs to be stopped for personnel safety, which cannot be realized. Digging and supporting anchors are operated in parallel, and factors such as dust and noise also pose great safety threats to workers. The cutting unit can only cut one feed at one stop operation, and the efficiency is relatively low.

c在步骤b进行的同时,锚支部3的进给滑块3.2通过齿轮齿条推动往前运动指定距离,锚支部俯仰液压缸3.10伸长至设定距离,反馈控制其停止伸长,使俯仰滑轨3.3摆动到指定角度,回转电机一3.7、回转电机二3.9、电机液压缸3.8三者共同动作,使得锚杆钻机3.6的位姿至指定位姿,锚杆钻机3.6进行打锚杆的动作将,锚网支护到巷道顶板上;c While step b is being carried out, the feed slider 3.2 of the anchor support 3 is pushed forward by a rack and pinion for a specified distance, and the anchor support pitching hydraulic cylinder 3.10 extends to the set distance, and feedback controls it to stop elongation and pitch The slide rail 3.3 swings to the specified angle, the rotary motor 1 3.7, the rotary motor 2 3.9, and the motor hydraulic cylinder 3.8 all act together to make the posture of the bolter 3.6 reach the specified posture, and the bolter 3.6 performs the action of bolting. Support the anchor net to the roof of the roadway;
d在截割头2.2完成一轮S形截割断面后,进给液压缸2.6再伸长一定距离,进行下一个S型截割断面,同时锚支部3的回转电机二3.9逆时针摆动一定角度,打下一根锚杆;d After the cutting head 2.2 completes a round of S-shaped cutting section, the feed hydraulic cylinder 2.6 extends a certain distance to carry out the next S-shaped cutting section, and at the same time, the rotary motor 2 of the anchor branch 3 swings a certain angle counterclockwise. , Lay an anchor rod;
e锚支部3完成一个断面上的打锚杆后,挡板滑板4.2后移,挡板滑板4.2退出临时支护,进给滑块3.2前移,进行下一个断面的锚杆支护;After the anchor support part 3 completes the anchoring of one section, the baffle slide 4.2 moves back, the baffle slide 4.2 exits the temporary support, and the feed slide 3.2 moves forward to carry out the anchor support of the next section;
f截割头2.2完成第二轮断面的S型截割后,进给液压缸2.6收缩,截割头2.2回收到初始位置,锚支部3的进给滑块3.2后退到底,锚支部俯仰液压缸3.10、回转电机一3.7、回转电机二3.9、电机液压缸3.8动作,锚支部3回到初始位置,纵轴式掘进机体1前后支撑缩回,纵轴式掘进机体1前进到下一个巷道断面处,重复步骤a-f动作。After the cutting head 2.2 completes the S-shaped cutting of the second round section, the feed hydraulic cylinder 2.6 shrinks, the cutting head 2.2 is recovered to the initial position, the feed slider 3.2 of the anchor support 3 is retracted to the end, and the anchor support pitch hydraulic cylinder 3.10. Rotary motor 1 3.7, rotary motor 2 3.9, motor hydraulic cylinder 3.8 act, the anchor support 3 returns to the initial position, the longitudinal axis tunneling machine body 1 is supported and retracted, and the longitudinal axis tunneling machine body 1 advances to the next roadway section. , Repeat step af action.
