The hydraulic pressure control unit includes: first to fourth inlet valves which are arranged on the individual upstream parts of the wheel cylinder to control the hydraulic pressure being transferred to the wheel cylinder installed on each vehicle wheel; first to fourth dump valves individually controlling the flow of the hydraulic pressure being discharged from the wheel cylinder; and first and second balance valves. The first balance valve is arranged between the inlet and dump valves and connects or cuts off two wheel cylinders having the first and second inlet valves connected thereto. The second balance valve connects or cuts off the two wheel cylinders having the third and fourth inlet valves connected thereto. COPYRIGHT KIPO 2016
  • [专利] Foundation structure
    (KR101537106) The present invention relates to a foundation structure, and more specifically, relates to a foundation structure which has a supporting surface receiving a weight of an equipment and has an upper part where the equipment is installed and a lower part where a cable or an oil pipe is installed, thereby preventing an obstacle from being placed on a road for workers. The foundation structure comprises: a base frame having a supporting surface with a predetermined height to receive the weight of the equipment installed in an upper part thereof; and a lower supporter coupled with an upper surface of the base frame to fixate the equipment to prevent the equipment from being moved. According to the present invention, the equipment is installed in the upper part of the foundation structure, and the cable or the oil pipe is installed in a lower part thereof, thereby minimizing interruption for the worker′s passage. Also, the equipment may firmly be supported by the upper part of the foundation structure and the equipment may be fixated without movement or be only released by a simple operation; thereby securing high work efficiency, preventing the equipment from shaking, and preventing accidents from occurring.
  • [专利] Device for transporting and placing a bridge of an offshore oil rig for sea operation onto a floating or stationary structure
    (KR101721706) A device for transporting and placing a bridge (1) of an offshore oil rig onto a floating or stationary mounting structure (3). The device has two parallel floating barges (10) for mounting the bridge (1). Each barge has a set of vertical movement rams (11) that move the bridge between a position of bearing on the barges (10) and a position of bearing on the structure (3). Each barge (10) has at least one assembly (15) for controlling the roll of each barge (10) in relation to the bridge (1) during the placement of the bridge onto the mounting structure (3). The assembly includes at least two rams (16) that are carried by the barge (10) and are located on both sides of the longitudinal axis of the barge (10). Each ram (16) is connected to the bridge (1) by a connecting member (17) that has rigid pull and flexible compression. (From US8753039 B2)
