为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请提供一种用于钻机的加压结构，所述钻机包括桅杆1及可滑动地安装于桅杆1的动力头2，如图1(参考图2)所示，所述加压结构包括：主卷扬、副卷扬、主卷扬钢丝绳6、副卷扬钢丝绳9、用于安装在桅杆1的顶部的第一滑轮4以及用于安装在桅杆1上且在动力头2下方的第二滑轮7；
其中，所述主卷扬包括用于设置在桅杆1侧面的主卷扬卷筒5，所述主卷扬钢丝绳6设置为绕在主卷扬卷筒5上，且沿远离主卷扬卷筒5的方向绕过第一滑轮4后能连接于动力头2；所述副卷扬包括用于设置在桅杆1侧面的副卷扬卷筒8，副卷扬钢丝绳9设置为绕在副卷扬卷筒8上，且沿远离副卷扬卷筒8的方向绕过第二滑轮7后能连接于动力头2。其中，主卷扬卷筒5和副卷扬卷筒8设置在桅杆1的侧面是指位于桅杆1的外围，并不仅仅是左右两侧，还可以是前侧或后侧。
本申请提供的加压结构，通过控制副卷扬卷筒8收卷副卷扬钢丝绳9能够对动力头2施加向下的压力，而在控制主卷扬卷筒5收卷主卷扬钢丝绳6能够向上提升动力头2。
在一个实施方式中，所述加压结构还包括用于安装在桅杆1上且在第二滑轮7上方的第三滑轮10，沿远离副卷扬卷筒8的方向，副卷扬钢丝绳9设置为从上方绕过第三滑轮10后再向下绕在第二滑轮7上。
可选地，第三滑轮10设置为安装在低于第一滑轮4的位置。这样，可以避 免主卷扬钢丝绳6和副卷扬钢丝绳9产生缠绕。
在一个实施方式中，所述主卷扬和副卷扬分别包括用于控制液压的浮动阀，以在副卷扬卷筒8收卷时能够使得主卷扬卷筒5同步放卷，而在主卷扬卷筒5收卷时能够使得副卷扬卷筒8同步放卷。所述加压结构还可以包括控制浮动阀的浮动开关。其中在液压系统中通过浮动阀控制液压从而在一个卷筒转动进行收卷时另一个卷筒处于浮动状态以能够跟随同步放卷是本领域技术人员能够实现的，在此不再详述。
可以理解的是，主卷扬卷筒5和副卷扬卷筒8的转动并不限于采用液压系统控制的方式，在其它实施方式中，也可以采用电机来控制主卷扬卷筒5和副卷扬卷筒8转动，在工作过程中，通过控制电机也可以实现在控制副卷扬卷筒8收卷时主卷扬卷筒5同步放卷，以及在主卷扬卷筒5收卷时副卷扬卷筒8同步放卷。
本申请提供的加压结构，结构简单，方便灵活，可以用于多工法钻机，适合多种工法施工。
本申请还提供一种钻机，如图1和图2，该钻机包括：桅杆1、可滑动地连接于所述桅杆1的动力头2以及用于驱动所述动力头2的加压结构。
所述加压结构包括：第一滑轮4、第二滑轮7、主卷扬、副卷扬、主卷扬钢丝绳6和副卷扬钢丝绳9。
其中，所述第一滑轮4设置于桅杆1的顶部，所述主卷扬包括位于桅杆1的一侧的主卷扬卷筒5，主卷扬钢丝绳6沿远离主卷扬卷筒5的方向绕经第一滑轮4后与动力头2连接；第二滑轮7设置于桅杆1的底部，所述副卷扬包括设置在桅杆1的侧面的副卷扬卷筒8；副卷扬钢丝绳9沿远离副卷扬卷筒8的方向绕过第二滑轮7后与动力头2连接。
本申请提供的钻机所采用的加压结构，结构简单，相比现有技术中的卷扬加压机构可以有效降低成本，而且该加压结构限制少，在钻机上采用该加压结构，可以将动力头2升高到桅杆1的较高位置，从而钻机应用广泛，适合于多 种工法的施工，例如，可以进行CFA、锚杆、预应力锚索、高压旋喷等工法的施工。另外，本申请提供的加压结构在用于钻机上时，主卷扬钢丝绳6和副卷扬钢丝绳9并不经过桅杆1的内部，因此可以避免钢丝绳与桅杆1的内部结构磨损所导致的钢丝绳寿命低的问题。
下面结合图1-图2描述本申请的一个实施方式提供的钻机。
该实施方式中，动力头2滑动设置于桅杆1上，桅杆1包括：主桅杆和安装在主桅杆上方的上桅杆3，上桅杆3设置于桅杆1的顶部，用于安装具有第一滑轮4的滑轮架；第一滑轮4设置于上桅杆3的顶部；主卷扬卷筒5位于桅杆1的一侧，用于给主卷扬钢丝绳6提供动力；主卷扬钢丝绳6缠绕于主卷扬卷筒5，且主卷扬钢丝绳6的一端与主卷扬卷筒5连接，另一端绕过第一滑轮4的顶部与动力头2的顶部连接；第二滑轮7设置于桅杆1的底部；副卷扬卷筒8设置于桅杆1的侧面；副卷扬钢丝绳9缠绕于副卷扬卷筒8，且一端与副卷扬卷筒8连接，另一端绕经第二滑轮7的底部并与动力头2的底部连接。
如图1-图2所示，主卷扬钢丝绳6从主卷扬卷筒5出发，在桅杆1外侧向上，通过第一滑轮4与动力头2顶部的吊耳连接。副卷扬钢丝绳9从副卷扬卷筒8出发，在桅杆1外侧向上，利用副卷扬卷筒8绕经桅杆1，到达桅杆1的另一侧，再向下通过布置在桅杆1底部的第二滑轮7，与动力头2的下方连接。
钢丝绳加压系统中的钢丝绳需要保持张紧状态，传统钢丝绳加压是采用张紧油缸张紧钢丝绳，本申请无需增加张紧油缸的配置，在完成整体的组装后，控制主卷扬卷筒5和副卷扬卷筒8同步转动(即主卷扬卷筒5收卷时副卷扬卷筒8同步放卷，而副卷扬卷筒8收卷时主卷扬卷筒5同步放卷)，具体可以使得其中一者的马达工作，另一者的马达不工作，通过使得所述另一者跟随所述一者转动的方式来完成钢丝绳加压系统的钢丝绳收紧。
在该实施方式中，加压结构还可以包括第三滑轮10，第三滑轮10设置在桅杆1上且在第一滑轮4和所述第二滑轮7之间的高度位置上，沿远离副卷扬卷筒8的方向，副卷扬钢丝绳9绕经第三滑轮10的顶部再绕经第二滑轮7的底 部后并与动力头2的底部连接，能够保证副卷扬卷筒8的出绳角以及入绳角，防止副卷扬钢丝绳9的卷绕。需要说明的是，当副卷扬卷筒8到第二滑轮7的空间距离足够长，可以保证副卷扬卷筒8的出绳角以及入绳角，则无需增加第三滑轮10，副卷扬钢丝绳9可以直接从副卷扬卷筒8连接至第二滑轮7。当然，主卷扬卷筒5和副卷扬卷筒8可以依据布置不同进行互换。
该实施方式中，设置第三滑轮10的高度低于第一滑轮4的高度，可以保证主卷扬钢丝绳6和副卷扬钢丝绳9在工作过程中互不干涉。
可选地，第三滑轮10可以安装在桅杆1顶部的上桅杆3上，即第一滑轮4和第三滑轮10均安装在上桅杆3上，这样在拆卸上桅杆3时可以一起将第一滑轮4和第三滑轮10一起拆卸下来。
为了进一步地优化上述技术方案，桅杆1还包括：加长下桅杆11，加长下桅杆11设置于桅杆1的主桅杆的底部，且第二滑轮7设置于加长下桅杆11上。
当需求配置不同工法施工时，利用旋挖工法既有的主卷扬卷筒5和副卷扬卷筒8完成钢丝绳加压系统，实现动力头的加压、下放及提升。
油缸加压系统与上述的钢丝绳加压结构可以进行切换，在切换至采用油缸加压系统加压时，拆除上桅杆3和加长下桅杆11，将加压油缸的固定端安装在桅杆1上，且伸缩端连接于动力头2，由此可以通过加压油缸对动力头2进行加压。
而在从油缸加压系统切换至采用本申请的加压结构进行加压时，将加压油缸拆卸下来，并将上桅杆3和加长下桅杆11装到桅杆1的主桅杆上，搭好主卷扬钢丝绳6和副卷扬钢丝绳9后，即可采用钢丝绳加压结构进行加压，两种加压方式切换简单方便。
为了进一步地优化上述技术方案，主卷扬卷筒5和副卷扬卷筒8在钢丝绳加压系统中需要同步，防止加压失效，在主卷扬和副卷扬上均设置有浮动阀，用于控制液压，并在加压操作系统中设置浮动开关。在进行加压以及下放的过程中，副卷扬马达工作，副卷扬卷筒8回转收卷副卷扬钢丝绳9时，主卷扬卷 筒5采用浮动状态，随着副卷扬卷筒8的动作同步放绳。在进行上提的过程中，主卷扬马达工作，主卷扬卷筒5收卷主卷扬钢丝绳6，副卷扬卷筒8采用浮动状态，随着主卷扬卷筒5的动作放绳，可以避免钢丝绳发生绞绳。
本申请提供的技术方案中，主卷扬钢丝绳6和副卷扬钢丝绳9采用在桅杆1外侧走线，解决了现有技术中钢丝绳需要从桅杆内部穿过，容易与桅杆内部的结构磨损，影响钢丝绳寿命的问题。
在需要进行CFA、锚杆、预应力锚索、高压旋喷等工法的施工时，需要动力头提升至最高点，并实现全行程加压。
在多工法状态下，钻机采用本申请提供的钢丝绳加压结构主要存在以下三种工况，参考图2：
加压工况：在钻杆12与地层接触时，动力头2与钻杆12连接，副卷扬马达工作，副卷扬卷筒8收卷副卷扬钢丝绳9，主卷扬卷筒5采用浮动状态，随着副卷扬卷筒8的动作放绳，即同步放卷。动力头2在副卷扬钢丝绳9的拉力作用下，将加压力传递给钻杆12，完成加压。
下放工况：在钻杆12与地层不接触，动力头2需要进行下放的过程中，副卷扬马达工作，副卷扬卷筒8收卷副卷扬钢丝绳9，主卷扬卷筒5采用浮动状态，随着副卷扬卷筒8的动作放绳。副卷扬做功和动力头2的自重做功抵抗主卷扬浮动阀的阻力后，才是驱动动力头2下降的功。可以防止动力头2突然加速掉落，产生安全隐患；动力头2沿着桅杆的1滑轨向下运动。
提升工况：在施工完成后，动力头2需要提升，在进行上提的过程中，主卷扬马达工作，主卷扬卷筒5收卷主卷扬钢丝绳6；副卷扬卷筒8采用浮动状态，随着主卷扬卷筒5的动作放绳；动力头2沿着桅杆1的滑轨向上运动。
本申请的另一方面实施例还公开了一种钻机，包括钻机本体13、桅杆1、钻杆12、动力头2和上述的加压结构，桅杆1设置于钻机本体13上，加压结构设置于桅杆1上，用于为动力头2加压，钻杆12连接在动力头2上。
本实施例提供的钻机，利用钻机既有的主卷扬和副卷扬，通过增加第二滑 轮7、第三滑轮10和第一滑轮4来实现动力头2的上提、下放及加压。
其中，钻杆12为锚杆、预应力锚索或旋喷管，根据实际工况自行选择。钻机本体13采用履带式行走底盘。
本申请另一方面实施例还公开了一种钻机，如图3所示，包括钻机本体13、桅杆1和动力头2，还包括上述的加压结构和加压油缸14，即上述的加压结构可以结合液压系统的加压油缸14使用，也可以单独使用，根据不同的工况切换，当采用加压油缸13对动力头2加压时，加压油缸14的固定端与桅杆1连接、其伸缩端与动力头2连接，动力头2可在加压油缸14的驱动下沿桅杆1的长度方向滑动移动。在切换至本申请提供的加压结构进行加压时，可以拆卸加压油缸14。加压油缸14和本申请提供的加压结构的具体切换方式可参考如上描述。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
