Description
技术领域technical field
本发明涉及矿物资源采掘机械领域,具体是一种深部矿井钻孔牵引装置。The invention relates to the field of mineral resource mining machinery, in particular to a deep mine drilling traction device.
背景技术Background technique
近些年,随着开采强度的不断加大,我国煤矿资源采掘深度以每年8米至12米的速度增加,一大批煤矿快速进入深部开采阶段,深部矿井采掘工作较为困难。In recent years, with the continuous increase of mining intensity, the mining depth of my country's coal mine resources has increased at a rate of 8 meters to 12 meters per year. A large number of coal mines have rapidly entered the deep mining stage, and deep mine mining is more difficult.
为了保障工作人员的安全,采掘煤矿之前,需要将煤储层间隙中的煤层气开采出来。煤层气开采时,需要先利用压裂器在作业区域的煤层上形成数条缝隙,此过程称为压裂。目前,压裂作业之前,需要钻取数百米深的通道,将缠绕在绞盘上的压裂器缓慢送入钻孔中。此过程存在以下问题:In order to ensure the safety of the staff, before mining the coal mine, it is necessary to extract the coalbed methane in the gap of the coal reservoir. When coalbed methane is exploited, it is necessary to use a fracturing device to form several cracks in the coal seam in the operation area. This process is called fracturing. Currently, prior to fracturing operations, it is necessary to drill a channel hundreds of meters deep and slowly feed the fracturing device wound on the winch into the borehole. This process has the following problems:
1.压裂器只能通过人工转动绞盘,缓慢地送入或取出数百米长的钻孔中,而没有其他的动力,压裂器送入钻孔深部与取出的过程费时又费力。1. The fracturing device can only be slowly sent into or taken out of the hundreds of meters long borehole by manually turning the winch, without other power, the process of sending the fracturing device into the deep part of the borehole and taking it out is time-consuming and laborious.
2.压裂器自身结构单一,无法自行掘进,应对异常情况的能力不足。如遇障碍物、矿体塌方等突发的异常情况,压裂器就只能送至此位置进行压裂作业,无法继续深入钻孔,进行压裂作业。2. The structure of the fracturing device is single, unable to excavate by itself, and the ability to deal with abnormal situations is insufficient. In case of unexpected abnormal situations such as obstacles and ore body collapse, the fracturing device can only be sent to this location for fracturing operations, and cannot continue to drill deeply for fracturing operations.
因此,有必要发明一种深部矿井钻孔牵引装置,使深部矿井开采装置能够适应深部矿井复杂的地质情况,较为轻松地送入钻孔的深部。Therefore, it is necessary to invent a deep mine drilling traction device, so that the deep mine mining device can adapt to the complicated geological conditions of the deep mine, and can be sent into the deep part of the borehole more easily.

Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
如图1至6所示,本发明提供了深部矿井钻孔牵引装置的具体实施方式,包括牵引头1、爬行机构2以及防爆电机3;As shown in Figures 1 to 6, the present invention provides a specific embodiment of a deep mine drilling traction device, including a
所述牵引头1包括圆柱形筒体101,转动安装于圆柱形筒体101中心孔内的转轴,同轴固定于转轴一端且伸出圆柱形筒体101的锥形圆台102,环设于锥形圆台102圆锥面上的螺旋齿103,同轴固定于锥形圆台102小端面上的锥形钻头104;The
所述爬行机构2包括同轴设置的至少两个钢筋箍201,沿所有钢筋箍201的轴向共同焊接于所有钢筋箍201外缘上的至少三个钢筋棍202,所述钢筋箍201和钢筋棍202组成筒形的钢筋架体,位于相邻钢筋棍202之间的钢筋箍201上转动安装有至少一个蜗轮203,所述钢筋架体内穿设有蜗杆204,且所有的蜗轮203均与蜗杆204相配合,所述蜗杆204内固设有输出轴208,所述输出轴208的一端与牵引头1的转轴另外一端同轴固定连接,所述钢筋棍202的一端与牵引头1的圆柱形筒体101相连接,所述输出轴208的另外一端与防爆电机3的输出端同轴固定连接,所述钢筋棍202的另外一端与防爆电机3的机壳相连接;所述钢筋架体的外径小于牵引头1的圆柱形筒体101和防爆电机3的外径,所有蜗轮203的最外侧的轮齿齿顶围成的圆的直径大于牵引头1的圆柱形筒体101和防爆电机3的外径。The
本发明提供了所述深部矿井钻孔牵引装置的具体工作流程:The present invention provides the specific working process of the deep mine drilling traction device:
(1)前进过程(1) Advance process
如图7所示,防爆电机3通过第五拉环302与压裂器相连。电缆固定于压裂器上,地上的电源通过电缆,与防爆电机3相连,为牵引装置提供电力。防爆电机3通过输出轴208,带动爬行机构2的蜗杆204转动,再传递给与蜗杆204相配合的蜗轮203,使蜗轮203向外转动并且带动爬行机构2向前爬行。牵引头1的螺旋齿103转动,掘进,同时将前方质地较硬的障碍物扫至一旁。爬行机构2与牵引头1相配合,牵引压裂器至钻孔深处。As shown in FIG. 7 , the explosion-
(2)后退过程(2) Backward process
电缆反接电源,使防爆电机3反转,驱动蜗杆204反转,再传递给蜗轮203,使蜗轮203向内转动并且带动爬行机构2向后爬行,牵引压裂器离开钻孔。The cable is reversely connected to the power supply, so that the explosion-
具体实施时,所述防爆电机3也可通过其他连接部件与压裂器相连。During specific implementation, the explosion-
具体使用时,为了能够使本发明所述的深部矿井钻孔牵引装置适应钻孔复杂多变的地质情况,进一步的,位于钢筋棍202外的所有钢筋箍201上均设有一个开口207;位于转轴另外一端的圆柱形筒体101的端面上沿圆周方向环设有至少三个第一拉环105,所述钢筋棍202的两端分别设有至少三个第二拉环205和第三拉环206,所述防爆电机3的机壳上环设有至少三个第四拉环301,所有第二拉环205与第一拉环105一一对应且相互穿套,所有第三拉环206与第四拉环301一一对应且相互穿套。由于钢筋箍201具有一定的弹性,开口207的设置能够使得钢筋箍201的直径有一定的变化余量,而且钢筋棍202的两端呈拉环连接结构(钢筋棍202相对于牵引头1和防爆电机3在径向方向上有一定的活动空间),当钻孔为不规则形状时,较窄位置处的钢筋箍201可根据钻孔的宽度压紧闭合(或部分闭合)开口207,钢筋架体部分位置处直径减小,使得此处的蜗轮203与蜗杆204紧密配合,蜗轮203随着蜗杆204的转动而转动;较宽处的钢筋箍201处于自由状态,钢筋架体部分位置处直径较大,使得此处的蜗轮203与蜗杆204处于接触配合的状态,蜗轮203可能随着蜗杆204的转动而转动。所以本发明所提供的钢筋架体能够根据钻孔的情况来自行改变其直径,减小钻孔内障碍物对钢筋架体的损坏,同时能够使得牵引过程更加流畅。由于钻孔的实际情况不可能为规则圆孔形状,因此本发明中的爬行机构2在实际使用过程中,可能会存在部分蜗轮203转动,部分蜗轮203不转的情况,但是这并不影响爬行机构2的前进和后退的使用。During specific use, in order to make the deep mine drilling traction device described in the present invention adapt to the complex and changeable geological conditions of drilling, further, an
如图3所示,所有蜗轮203分别间隔设于钢筋架体上的钢筋箍201上。在保证动力的基础上,这样可以提升钢筋架体整体的刚度。As shown in FIG. 3 , all the worm gears 203 are arranged at intervals on the
具体的,所有钢筋箍201上的开口207位置位于同一直线上。使用时,如图5所示,位于开口207处的钢筋箍201上不可设置钢筋棍202,为了保持爬行机构2周向运行的稳定性和均一性,如图6所示,位于开口207两侧的钢筋箍201上分别也设置有一个涡轮203。Specifically, the positions of the
在钻孔掘进矿井塌方等因素产生的障碍物时,为了便于监控牵引头1的工作状况,靠近锥形圆台102的圆柱形筒体101端面上设有摄像头106。优选的,所述摄像头106位于螺旋齿103的外侧,避免螺旋齿103阻碍摄像头106视野。In order to facilitate monitoring the working conditions of the
如图2所示,所述靠近锥形圆台102的圆柱形筒体101端面呈与锥形圆台102过渡配合的锥形面。As shown in FIG. 2 , the end surface of the
进一步的,为了提升钢筋棍202与钢筋箍201的连接紧密性,提升钢筋架体的刚度,与钢筋棍202相对应的钢筋箍201外缘上开设有与钢筋棍202相适配的弧形凹槽。弧形凹槽增加了钢筋棍202和钢筋箍201之间的接触面积,提升了连接强度。Further, in order to improve the tightness of the connection between the
以上所述,仅为本发明的具体实施方式,但本发明的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本发明揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本发明的保护范围之内。因此,本发明的保护范围应以所述权利要求的保护范围为准。The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. Should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
