具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例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公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
除非另作定义，此处使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开专利申请说明书以及权利要求书中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现在“包括”或者“包含”前面的元件或者物件涵盖出现在“包 括”或者“包含”后面列举的元件或者物件及其等同，并不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相对位置关系也可能相应地改变。
在柱塞泵中，由于柱塞不断往复运动，盘根压帽等紧固件会因震动等因素导致螺纹松动后退，从而可能导致盘根压帽等紧固件与其他部件(例如，柱塞卡箍)发生撞击使得设备损坏。现场人员需对盘根压帽等紧固件定期进行排查紧固(例如，每隔2至3小时)，从而影响现场作业效率及作业安全。
本公开的实施提供一种防松装置以及柱塞泵，能够有效地解决盘根压帽松动的问题，减少人员排查次数，提高作业效率，保证设备运行安全。
本公开的实施提供的防松装置，包括：第一支架、第二支架和弹性构件。第一支架包括：第一卡接部，限定第一容纳空间；第一连接部，在第一方向上延伸且固定连接到所述第一卡接部；以及限位部，经由所述第一连接部固定连接到所述第一卡接部，其中，所述限位部在垂直于所述第一方向的第二方向凸出于所述第一连接部。第二支架包括第二卡接部，限定第二容纳空间，其中，所述第二卡接部在所述第一方向上与所述第一卡接部相对，以及第二连接部，在所述第一方向上延伸且固定连接到所述第二卡接部。弹性构件连接所述第一支架和所述第二支架，构造为控制所述第一支架和所述第二支架在所述第一方向上相对移动。
这样，通过将第一卡接部和第二卡接部抵接到柱塞泵两个相邻间隔架上，且将限位部的相反于第一连接部的端部插入紧固件的定位孔中，能够有效的防止紧固件在松动方向上转动。此外，利用利用弹性构件的伸缩第一支架和第二支架可产生相对移动，这样能够在不依赖其他工具的情况下将防松装置安装到间隔架和紧固件上或者从其上拆除，从而增加了防松装置的拆装便利性。
图1示出根据本公开实施例的防松装置的立体示意图；图2示出根据本公开实施例的防松装置的各个部分在拆散状态下的立体示意图。
参见图1和图2，本公开的实施例提供的防松装置S，包括：第一支架F1和第二支架F2。例如，第一支架F1和第二支架F2的材料为刚性材料，例如金属，更具体的，钢材。当安装到柱塞泵的间隔架和紧固件上的情况下，第一 支架F1和第二支架F2能够承受柱塞泵作业期间的各种震动对其产生的应力而不产生实质变形。
第一支架F1包括固定连接的第一卡接部1、第一连接部2和限位部3。
第一卡接部1限定第一容纳空间K1。第一卡接部1构造为卡接在柱塞泵的第一间隔架上，使得第一间隔架的至少一部分位于第一容纳空间K1中。
第一连接部1在第一方向X上延伸。限位部3经由第一连接部1固定连接到第一卡接部1。例如，第一卡接部1、第一连接部2和限位部3通过焊接固定连接为一个整体。然而，本公开实施例并不限制第一卡接部1、第一连接部2和限位部3的固定连接方式。
限位部3在垂直于第一方向X的第二方向Y凸出于第一连接部2。限位部3在第二方向Y上远离第一连接部2的端部构造为插入紧固件的定位孔中。
第二支架F2包括固定连接的第二卡接部4和第二连接部5。
第二卡接部4限定第二容纳空间K2；第二卡接部4构造为卡接在柱塞泵的第二间隔架上，使得第二间隔架的至少一部分位于第二容纳空间K2中。
第二卡接部4在第一方向X上与第一卡接部1相对。
第二连接部5在第一方向X上延伸。第二连接部5在第一方向X上可移动连接到第一连接部2。
在限位部3在第二方向Y上远离第一连接部2的端部插在紧固件的定位孔中且第一卡接部1和第二卡接部4分别卡接在第一间隔架和第二间隔架上的情况下，如果紧固件要发生松动会带动第一支架F1朝向第一间隔架所在的第一侧转动，由于第一支架F1作为一个刚性支撑体已经抵靠在第一间隔架上，第一间隔架限制了第一支架F1进一步朝第一间隔架的转动。因此，第一间隔架经由第一支架F1对紧固件提供朝向第二间隔架所在的第二侧的抵抗力从而限制紧固件在松动方向上转动。此外，第一卡接部1和第二卡接部4可拆卸的卡接在位于柱塞泵外侧的第一间隔架和第二间隔架，一方面可以增强防松装置S的安装稳定性，另一方面可提高防松装置的安装便捷性。
在本实施例中，第二连接部5插入第一连接部2中，在第二方向Y上第一连接部2与第二连接部5部分重叠。这样，第一连接部2和第二连接部5彼此嵌套从而能够稳定的在第一方向上相对移动。
例如，第一连接部2具有管形形状；第二连接部5具有柱形形状；第二 连接部5插入第一连接部2内。例如，第一连接部2的轴向为第一方向X；第二连接部5的轴向为第一方向X。第一连接部2与第二连接部5同轴设置。
更具体的，第一连接部2具有圆管形形状；第二连接部5具有圆柱形形状。然而本公开的实施例并不限制第一连接部2和第二连接部5的具体形状。
限位部3例如具有柱形形状。限位部3的轴向例如为Y方向。例如，限位部3包括在远离第一连接部2的方向上顺次排列的第一圆柱部分31、圆锥台部分32和第二圆柱部分33。第一圆柱部分31、圆锥台部分32和第二圆柱部分33同轴设置。第一圆柱部分31的直径大于第二圆柱部分33的直径。这样，一方面可以保证限位部3具有较大的抗变形能力，另一方面可以便于第二圆柱部分33插入紧固件的定位孔中。
防松装置S还包括：位于第一连接部2内的弹性构件7。弹性构件7抵接第一卡接部1和第二连接部5。
例如，弹性构件7为弹簧。第二连接部5的靠近弹簧的一端设置有凸起部51，当弹簧7抵接第二连接部5时，凸起部51插入弹簧7内。
在上述实施例中，第二连接部5插入第一连接部2中，然而本公开的实施例并不限于此第一连接部和第二连接部的嵌套关系。在另一实施例中，与限位部和第一卡接部固定连接的第一连接部插入与第二卡接部固定连接的第二连接部中。
在上述实施例中，弹性构件7位于第一连接部2内。然而本公开的实施例并不限于此。只要弹性构件7能够通过抵接第一支架F1和第二支架F2而控制第一支架F1和第二支架F2在第一方向上相对移动即可。
第一连接部2上设置有开口21。
防松装置S还包括突出构件6。突出构件6通过开口21可拆卸连接到第二连接部5。
在本实施例中，第二连接部5上设置有内螺纹孔，突出构件6的靠近第二连接部5的端部上设置有与该内螺纹孔匹配的外螺纹结构。突出构件6通过该内螺纹孔和该外螺纹结构可拆卸连接于第二连接部5。突出构件6凸出于第一连接部2的外表面。这里，并不限制突出构件6可拆卸连接到第二连接部5的具体方式。
例如，突出构件6在第三方向上凸出于第一连接部，第三方向与第一方 向X和第二方向Y相交。例如，第三方向为垂直于第一方向X和第二方向Y的方向Z。例如，突出构件6例如具有柱形形状。突出构件6的轴向为第三方向Z。
例如，开口21具有在第一方向X延伸的条形形状。突出构件6沿第一方向X在开口21中的能够移动的最大距离大于第二卡接部在第一方向上的最大尺寸。这样，可便于防松装置的安装。
例如，第一卡接部1由第一板形构件11和第二板形构件12组成，其中，第一板形构件11在第一方向X上与第一连接部2重叠，第二板形构件12位于第一板形构件11在第二方向Y上远离限位部3的一端。这样可以减少在安装防松装置时对弹性构件的压缩程度。
例如，在第一方向X和第二方向Y所在的平面上，第一卡接部1具有L形的截面形状。
例如，第二卡接部4包括第三板形构件41和连接到第三板形构件41的第四板形构件42和第五板形构件43。
在第一方向X上，第三板形构件41与第二连接部5重叠；在第二方向Y上，第四板形构件42位于第三板形构件41靠近限位部3的一端。在第二方向Y上，第五板形构件43位于第三板形构件41远离限位部3的一端。
例如，第一板形构件11、第二板形构件12、第三板形构件41、第四板形构件42和第五板形构件43每个为平板形状。然而，在另外的示例中，第一板形构件11、第二板形构件12、第三板形构件41、第四板形构件42和第五板形构件43的任一个可以具有其他的形状，例如弧形板形状。
例如，第一板形构件11垂直于第一方向X，第二板形构件12垂直于第二方向Y。
例如，第三板形构件41垂直于第一方向X，第四板形构件42和第五板形构件43均垂直于第二方向Y。
在装配防松装置S时，首先将弹簧7放入第一支架F1的第一连接部2中，再将第二支架F2的第二连接部5放入第一支架F1的第一连接部2中，最后将突出构件6拧入第二支架F2上的螺纹孔52中。可以通过推动突出构件6来控制防松装置S在柱塞泵上的安装和拆卸。
图3示出根据本公开实施例的柱塞泵的部分立体示意图，其中，包括防 松装置的部分被放大示出。
参见图3，本公开另一实施例提供的柱塞泵，包括：液力端20，在锁紧方向上旋转而安装在液力端20的一侧上的紧固件40，固定连接到液力端20的一侧上的第一间隔架R1和第二间隔架R2以及防松装置S。例如，锁紧方向为顺时针方向，松动方向为逆时针方向。
紧固件40包括多个定位孔H。
防松装置S的第一卡接部1抵接第一间隔架R1使得第一间隔架R1的至少一部分位于第一容纳空间中；防松装置S的第二卡接部4抵接第二间隔架R2使得第二间隔架R2的至少一部分位于第二容纳空间中，限位部3的相反于第一连接部2的端部沿第二方向Y插入紧固件40的定位孔H的任一个中。弹性构件7处于弹性形变状态。
处于弹性形变状态的弹性构件对第一支架和第二支架提供在第一方向上相互远离的作用力，使得第一支架和第二支架分别稳固抵接在第一间隔架和第二间隔架上。
在锁紧方向上第一间隔架R1位于第二间隔架R2上游。也就是，在垂直于紧固件40的轴向的平面内，紧固件40的中心与第一间隔架R1的直线连线为第一直线连线，紧固件40的中心与第二间隔架R2的直线连线为第二直线连线，第一直线连线绕紧固件40的轴向沿锁紧方向转动一锐角角度可与第二直线连线重合。
例如，在第一方向X上，防松装置S的限位部3位于第一间隔架R1和第二间隔架R2之间。
例如，第一间隔架R1平行于第二间隔架R2。
柱塞泵还包括活动连接到液力端的柱塞50。紧固件40为与柱塞50同轴设置的盘根压帽。
紧固件40的多个定位孔H的每个例如在紧固件40的径向方向延伸。
