    • A floating clamping device for an injection head of a continuous oil pipe, including a drive sprocket, a transmission chain, a supporting plate, a pushing plate, clamping oil cylinders and a clamping assembly. At least two clamping oil cylinders are installed on the supporting plate fixedly. The pushing plate is fixed on the supporting plate through a pin shaft. The clamping assembly includes a saddle-shaped clamping block, a clamping block seat and rollers which are mounted on the clamping block seat. The clamping assembly is mounted on the transmission chain. A piston rod of the clamping oil cylinder is pressed on one face of the pushing plate, while the other face of the pushing plate is pressed on the rollers. The pushing plate has a simple structure and is convenient for maintenance; the clamping device has a compact structure and a reduced volume.
    • 一种用于连续油管的注射头的浮动夹紧装置,包括驱动链轮,传动链,支撑板,推板,夹紧油缸和夹紧组件。 至少两个夹紧油缸固定在支撑板上。 推板通过销轴固定在支撑板上。 夹紧组件包括鞍形夹紧块,夹紧块座和安装在夹紧座座上的辊。 夹紧组件安装在传动链上。 夹紧油缸的活塞杆被压在推板的一个面上,而推板的另一面被压在辊子上。 推板结构简单,维修方便; 夹紧装置具有紧凑的结构和减小的体积。

    • Provided are systems and methods for communication protocol mapping. A first computing device uses a first communication protocol while a second computing device uses a second communication protocol. In some implementations, the first communication protocol and the second communication protocol are for different service domains. In accordance with an embodiment of the disclosure, a server is configured to map communication between the different service domains. In some implementations, the first communication protocol is a protocol conforming to Representational State Transfer ‘REST’ and the second communication protocol is a Session Initiation Protocol ‘SIP’. In accordance with another embodiment of the disclosure, a server is configured to map communication between the protocol conforming to REST and SIP, regardless of whether different service domains are involved.
    • 提供了用于通信协议映射的系统和方法。 当第二计算设备使用第二通信协议时,第一计算设备使用第一通信协议。 在一些实现中,第一通信协议和第二通信协议用于不同的服务域。 根据本公开的实施例,服务器被配置为映射不同服务域之间的通信。 在一些实现中,第一通信协议是符合表示状态传输“REST”的协议,第二通信协议是会话发起协议SIP。 根据本公开的另一实施例,服务器被配置为映射符合REST和SIP的协议之间的通信,而不管涉及不同的服务域。
