上座12的第二端和下座11的第二端通过调节组件13相连，用于调节上座12和下座11之间的枢转角度。
根据本公开实施例的气举反循环钻进装置1000，上座12的第一端与下座11的第一端可枢转地相连，可以使上座12以下座11第一端为端点进行旋转，进而使上座12和下座11之间形成一个倾角，上座12的第二端通过调节组件13与下座11的第二端相连，通过对调节组件13的长度(从上座12的第二端到下座11的第二端之间调节组件13的长度)进行调节，以调节上座12和下座11之间的夹角。其中，调节组件13的长度越长，则上座12和下座11之间的夹角越大。其中，上座12和下座11之间的夹角不超过90°。
可以理解的是，当需要在具有一定坡度的环境中(斜坡)进行打孔作业时，套管与钻机(气举反循环钻机等)需要保持同轴，则需要通过对调节组件13的长度进行调节，以使安装在上座12上的钻机与套筒同轴。其中，调节组件13可以通过是气压缸、液压缸、电机等驱动。
同时，动力装置20可枢转地设在斜孔座10上，可以通过调节动力装置20与斜孔座10之间的夹角，在后续的安装过程中，由于动力装置20与斜孔座10存在一定角度，进而降低了安装钻杆60所需的高度，使钻杆60便于安装且由于安装高度降低，增加了 施工安全性。
因此，根据本公开实施例的气举反循环钻进装置1000，具有结构简单、减小因安装面水平度造成的误差、安全性高和应用范围广的优点。
在一些具体的实施例中，调节组件13可以是由驱动装置驱动的伸缩杆，折叠支架等。
在一些实施例中，动力装置20包括门架21和动力头22，动力头22可枢转地设在门架21上。
其中，门架21包括第一立柱211、第二立柱212和主横梁213。第一立柱211可枢转地设在上座12上。
第二立柱212可枢转地设在上座12上，且与第一立柱211沿第一水平方向间隔设置。
主横梁213可滑动地设于第一立柱211和第二立柱212之间。动力头22可枢转地与主横梁213相连。
根据本公开实施例的气举反循环钻进装置1000，动力头22可枢转地设在门架21上，可以便于后续钻杆60的安装。具体地，在气举反循环钻机工作过程中，钻杆60首先需要伸入到钻孔内，此时则需要使动力头22和钻孔之间预留一个钻杆60的长度。而当动力头22可摆动地安装在门架21上时，将动力头22进行旋转，此时安钻管时，可以根据动力头22偏转的角度确定动力头22与钻孔之间的垂直距离，可以理解的是，动力头22偏转角度越大，动力头22与钻孔之间所需的垂直距离越小。其中，动力头22偏转角度在1°至90°，优选地，动力头22偏转角度为45°
可以理解的是，根据本公开实施例的气举反循环钻进装置1000具有结构简单，操作安全，便于安装的优点。
在一些实施例中，门架21还包括第一副横梁214、第二副横梁215和第三副横梁216，第一副横梁214分别与第一立柱211和第二立柱212相连，且与动力头22在前后方向上相邻，第二副横梁215分别与第一立柱211和第二立柱212相连，且在上下方向上与第一副横梁214相间隔，第三副横梁216分别与第一立柱211和第二立柱212相连，且在前后方向上与第二副横梁215相对。
根据本公开实施例的气举反循环钻进装置1000，通过第一副横梁214可以和驱动装置相连，进而可以使驱动装置通过第一副横梁214同时对第一立柱211和第二立柱212进行控制以调节第一立柱211和第二立柱212与斜孔座10之间的角度，同时由于通过第一副横梁214同时控制，可以保证第一立柱211和第二立柱212转动的角度相同。
通过第二副横梁215和第三副横梁216可以进一步加强第一立柱211和第二立柱212之间结构的稳定性，同时通过第二副横梁215和第三副横梁216可以对动力头22的摆动角度进行限制。
在一些实施例中，门架21还包括耐磨层217，耐磨层217分别设在第一立柱211 和主横梁213之间和第二立柱212和主横梁213之间。
根据本公开实施例的气举反循环钻进装置1000，通过耐磨层217还可以减少门架21的磨损，进而延长门架21的使用寿命。在一些具体地实施例中，耐磨层217可以用于调节门架21中其它部件之间的垂直度。
在一些实施例中，气举反循环钻进装置1000还包括气体供给装置30、第一进气管40、第二进气管50、钻杆60、排渣管70、第一阀门401、第二阀门402和U型管80。
气体供给装置30用于提供气体介质。第一进气管40的第一端与气体供给装置30相连。第二进气管50与第一进气管40的第二端相连。
钻杆60的部分套设在第二进气管50中，钻杆60的另外部分露出于第二进气管50上端并与动力装置20相连。
排渣管70的第一端与动力装置20相连，排渣管70的第二端与沉渣装置90相连。
第一阀门401设在第一进气管40上。第二阀门402与第一阀门401间隔设在第一进气管40上。动力头22通过U型管80与排渣管70相连。
根据本公开实施例的气举反循环钻进装置1000，第二进气管50的部分位于钻孔中，气体供给装置30通过第一进气管40向第二进气管50中提供空气介质，优选地，气体供给装置30用于向第二进气管50中提供压缩空气，压缩空气进入第二进气管50后，压缩空气对钻孔内的泥浆加压，使泥浆通过钻杆60向排渣管70流动，并通过排渣管70排入沉渣装置90中进行沉淀。其中，经沉渣装置90沉淀后的清水可以再次排入钻孔中进行利用。
通过第一阀门401可以控制压缩空气进入第二气管的流量，进而可以控制对泥浆施加的压力，以控制泥浆的排出速度。
通过在第一进气管40上设置与第一阀门401间隔的第二阀门402，可以进一步控制从空气供给装置中输送而来的压缩空气的流量，进而进一步对泥浆的排出速度进行控制。
动力头22通过U型管80与排渣管70相连可以有效防止在泥浆排出过程中，发生倒流现象，导致泥浆排出速度减缓，甚至泥浆排出停止。
可以理解的是，根据本公开实施例的气举反循环钻进装置1000，压缩空气从钻杆60的外周侧向钻孔内的泥浆加压，可以使泥浆从钻杆60进入排渣管70中，进而可以对第二进气管50的内壁进行防护，延长了第二进气管50的使用寿命。
在一些实施例中，排渣管70包括第一子管701和第二子管702，第一子管701的第一端与钻杆60相连，第一子管701的第二端与第二子管702的第一端相连，第二子管702的第二端与沉渣装置90相连。第一子管701和第二子管702通过弧形管703相连。第一子管701上设有第三阀门7011。
根据本公开实施例的气举反循环钻进装置1000，第一子管701和第二子管702通过弧形管703相连，可以进一步防止在泥浆排出过程中，泥浆发生倒流，且第二子管702向下延伸，可以使进入到第二子管702中的泥浆通过重力自动排出。可以理解的是，弧形管703可以是鹅颈管。
通过第三阀门7011的设置，可以进一步防止泥浆排出过程中，泥浆发生倒流。
在一些实施例中，沉渣装置90包括多个沉淀池901，多个沉淀池901依次相连，且多个沉淀池901的上端开口。
根据本公开实施例的气举反循环钻进装置1000，通过多个沉淀池901对从排渣管70中输送而来的泥浆进行沉淀，使比重较大的泥沙在多个沉淀池901中沉淀后，可以对多次沉淀后的废水再次进行利用，其中，每个沉淀池901之间可以通过泵相连。
在一些实施例中，每个沉淀池901的高度沿水流方向依次降低。
根据本公开实施例的气举反循环钻进装置1000，由于水流方向每个沉淀池901的高度逐渐降低，进而可以使多个沉淀池901内的经过沉淀的废水通过溢流的方式逐渐向后六区，进而可以减少成本。
在一些实施例中，每个沉淀池901内设有用于过滤的格栅。
根据本公开实施例的气举反循环钻进装置1000，通过格栅可以进一步对每个沉淀池901内的废水进行过滤。其中，每个沉淀池901的进水口位于栅栏下方，出水口位于栅栏上方。
