2、结构特征与工作原理
DD、DDZ 系列吊卡主要有左主体、右主体、卡页、拉板（1 型）或锁钩（2 型）、卡 页轴和铰链铀等零件组成。左、右主体通过铰链铀连接。卡页被卡页轴固定在左主体上， 并围绕卡页轴转动，扭簧安装在卡页轴上，起自动复位作用。铰链轴、卡页轴由弹性挡圈 限位，拆卸较为方便。1 型吊卡中的拉板和扭簧由拉板销固定在卡页上，拉板在扭簧的作 用下，起开合和锁紧吊卡的作用；2 型吊卡中的锁钩和扭簧由螺栓安装在卡页上，并固定。 锁钩的钩子在扭簧的作用下，钩紧右主体上的钩紧销，达到锁紧的目的。吊卡左右两端设 计有挡环，以防吊卡在提升作业时从吊环中滑出。

To use the type 1 elevator, pull outward the shield, the upper slope of 45º separate from the body it attached, and pull outward on, the latch can separate from the latch cam of the other body, and then the elevator is opened for operation. To use the type 2 elevator, pull outward the handle of the latch lock, the hook separate from the lock pin with the force of small wrench spring, and pull outward on, the latch can separate from the latch cam of the body, and then the elevator is opened for operation. When close the elevator, grasp the two handle of the two halves body and pull them together, the latch will automatically hook the latch cam, or the shield will press latch or latch lock will hook the hook pin, the elevator will be closed and locked tightly. Then the operation of ascending or descending can be carried out.
1 型吊卡在工作时，顺时针扳转拉板，Fra Baidu bibliotek拉板上端 45º斜面脱离右主体，继续向外拉， 卡页从右主体的锁舌上脱开，吊卡即被打开进入工作状态。2 型吊卡在工作时，顺时针拉 动锁钩上的把手，钩子从钩紧销上脱落。继续向外拉，卡页从右主体的锁舌上脱开，吊卡 即被打开，钻杆可以自由进出。关闭时，只要握住左、右主体上的手柄，向内合紧，卡页 在大扭簧的作用下自动卡住右主体的锁舌，拉板或锁钩在小扭簧的作用下，也紧紧的压紧 卡页或钩住钩紧销，吊卡完全闭合与锁紧。这时就可进行提升或下降作业。

close the elevator safely. Every elevator has been equipped with two link blocks at both end, such can prevent the elevator fall off from elevator link in lifting operation.
DESCRIPTION: DD, DDZ type Elevators are convention bottleneck center latch elevators to handle
pipes in oil and gas drilling operation. Read the Manual before use the product. DD, DDZ type elevators are made from high quality alloy steel with both advanced

technology and heat treatment. The elevators are verified by strength test and NDT referred to ANSI/ASTM A487. The elevators can handle taper shoulder drill pipe from 2⅜" to 5½" O.D., plain drill pipe from 3½" to 5½", and tubing from 1.9" to 4½" O.D. at the temperature minus 20℃. The rating loads are as follows: 585kN, 712kN, 900kN, 1125kN, 1350kN, 2250kN, 3150kN, 4500kN and etc.
Center Latch Elevators have been strictly Volumetric Radiographic Tested and Surface NDE and Verification tested and Ex-work tested, every technical parameters and properties of the equipment offered to customers are in accordance with the specifications of API Spec 8C and SY/T 5035 Elevator link, Elevator and Manual Tong.
STRUCTURAL PRINCIPLE: DD, DDZ Center Latch Elevators Series are constructed in two halves of bodies,
latch, latch lock (type 1), or shield (type 2), latch pin, hinge pin, and other spare parts. The two bodies are hinged by hinge pin; the latch is jointed to one body by latch pin and can be rotated around it. The wrench spring is fixed to the latch and can be functioned as restoring. Latch pin and hinge pin are retained by snap spring, which is easy for assemble for disassemble. Shield and wrench spring of type 1 elevator are stationed on latch by shield pin, and the shield can be used to close or open elevator with the force of wrench spring. Latch lock and wrench spring of type 2 elevator are stationed on the latch by bolt. With the force of wrench spring, the latch lock can hook the lock pin of to
