具体实施方式detailed description
下面结合附图对本发明做进一步说明，但本发明并不局限于以下实施例。The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited to the following embodiments.
如图1所示，本发明提供的水下水平管汇连接器安装工具上的定位锁紧机构包括设于所述安装工具前端的2个定位板8；2个定位板8之间连接一个传动板4，该传动板4设于定位板8的上端部，且能沿定位板8上下移动，传动板4的下端面为圆弧面。As shown in Figure 1, the positioning and locking mechanism on the underwater horizontal manifold connector installation tool provided by the present invention includes two positioning plates 8 arranged at the front end of the installation tool; a transmission mechanism is connected between the two positioning plates 8 Plate 4, the transmission plate 4 is arranged on the upper end of the positioning plate 8, and can move up and down along the positioning plate 8, the lower end surface of the transmission plate 4 is an arc surface.
如图1所示，本发明定位锁紧机构还包括设于安装工具顶部的前提杆2和曲柄3，该前提杆2与安装工具之间为旋转连接，而前提杆2与曲柄3之间通过螺栓9进行固定连接，从而当前提杆2在水中水流和自身重力的作用下横放时，曲柄3会在前提杆2的带动下进行旋转，同时，曲柄3可推动传动板4向下移动。As shown in Figure 1, the positioning and locking mechanism of the present invention also includes a premise rod 2 and a crank 3 arranged on the top of the installation tool. The bolt 9 is fixedly connected, so that when the forelift rod 2 is placed horizontally under the action of the current in the water and its own gravity, the crank 3 will rotate under the drive of the premise rod 2, and meanwhile, the crank 3 can push the transmission plate 4 to move downward.
如图1所示，2个定位板8的相对的端面上分别设有一个推杆13，该推杆13可沿定位板8上下移动。在推杆13的上端连接有弹簧5；在定位板8上于推杆13的下部设有锁紧旋转块6，两者通过螺栓7进行连接。该锁紧旋转块6上设有圆弧面；当传动板4向下移动时，其会推动推杆13向下移动，而推杆13下移则会推动锁紧旋转块6旋转。As shown in FIG. 1 , a push rod 13 is provided on opposite end surfaces of the two positioning plates 8 , and the push rod 13 can move up and down along the positioning plate 8 . A spring 5 is connected to the upper end of the push rod 13 ; a locking rotating block 6 is arranged on the lower part of the push rod 13 on the positioning plate 8 , and the two are connected by bolts 7 . The locking rotary block 6 is provided with an arc surface; when the transmission plate 4 moves downward, it will push the push rod 13 to move downward, and the downward movement of the push rod 13 will push the locking rotary block 6 to rotate.
图2所示为本发明的定位锁紧机构与连接器配合时的示意图，本发明的使用方法如下：Figure 2 is a schematic diagram of the positioning and locking mechanism of the present invention when it cooperates with the connector. The method of use of the present invention is as follows:
当水平连接器主体下放到毂座上之后，需要下放安装工具对其实施安装。当缆绳1吊放安装工具上方，通过定位板8与管汇上事先安装的毂座上的定位设施12相配合实现粗对中，与此同时，在下放过程中，传动板4内圆弧面与公毂座11外壁相配合，也具有一定的对中作用。之后缆绳1继续下放，前提杆2和后提杆10在水流和重力作用下势必横落，从而带动与之固连的曲柄3旋转，而此时曲柄3相当于杠杆，利用相对较小的重力产生向下较大的驱动力，向下推动传动板4下移，定位板4两侧的推杆13推动锁紧旋转块6抱紧公毂座11，在传动板4和锁紧旋转块6的共同圆弧面与公毂座11的配合下牢牢抱紧，而此时要想扰动安装工具，便需要较大的驱动力。After the main body of the horizontal connector is lowered onto the hub, it is necessary to lower the installation tool to install it. When the cable 1 is hoisted above the installation tool, the positioning plate 8 cooperates with the positioning facility 12 on the pre-installed hub seat on the manifold to realize rough centering. At the same time, during the lowering process, the inner arc surface of the transmission plate 4 Cooperating with the outer wall of the male hub seat 11 also has a certain centering effect. Afterwards, the cable 1 continues to be lowered, and the premise rod 2 and the rear lifting rod 10 are bound to fall horizontally under the action of water flow and gravity, thereby driving the crank 3 fixedly connected therewith to rotate. At this time, the crank 3 is equivalent to a lever, which is generated by relatively small gravity. Larger downward driving force pushes the transmission plate 4 downwards to move down, and the push rods 13 on both sides of the positioning plate 4 push the locking rotating block 6 to hold the male hub seat 11 tightly. Under the cooperation of the common arc surface and the male hub seat 11, they are tightly hugged, and at this time, if the installation tool is to be disturbed, a relatively large driving force is required.
当安装工具实施安装之后，前提杆2和后提杆10在缆绳1的上提作用向上提起，此时传动板4在弹簧5的作用下向上运动，从而锁紧旋转块6便可以旋转，此时缆绳1继续上提，便可以携带安装工具整体撤离，完成回收操作。After the installation tool is installed, the premise rod 2 and the rear lifting rod 10 are lifted up by the lifting effect of the cable 1. At this time, the transmission plate 4 moves upward under the action of the spring 5, so that the rotating block 6 can be locked and rotated. When the cable 1 continues to be lifted, the installation tool can be carried to evacuate as a whole, and the recovery operation is completed.
上述各实施例仅用于说明本发明，其中各部件的结构、连接方式等都是可以有所变化的，凡是在本发明技术方案的基础上进行的等同变换和改进，均不应排除在本发明的保护范围之外。Above-mentioned each embodiment is only for illustrating the present invention, wherein the structure of each component, connection mode etc. all can be changed to some extent, every equivalent conversion and improvement carried out on the basis of the technical solution of the present invention, all should not be excluded from the present invention. outside the scope of protection of the invention.
