Embodiment Construction
[0022] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] The design verification load test system of the intermediate traveling block of the present invention, the structure is shown in figure 1 and figure 2 As shown, it includes bearing base 1, one end of bearing column 6 is fixed on bearing base 1, and the other end of bearing column 6 passes through the middle part of the traveling block to be tested, and connects with hydraulic cylinder 15 piston rod through clamp 12 and bolts. One end of the cavity protrudes from the protruding head on the rod to connect, the two side walls of the plug cavity of the hydraulic cylinder 15 are placed inside the frame side wall of the load-bearing frame 16, and a pad is arranged between the plug cavity of the hydraulic cylinder 15 and the inside of the frame side wall of the load-bearing frame 16 Plate 17, the end face of hydraulic cylinder 15 plug cavit...

The invention discloses a medium through type travelling block design verification load test system. The system includes a bearing seat. The bearing seat is fixedly connected to one end of a bearing column. The other end of the bearing column passes through the middle part of a to-be-tested travelling block, and is connected to a protruding head on an extension bar on one end of a hydraulic cylinder piston rod cavity through a clamp and bolts. The two sidewalls of the piston cavity of a hydraulic cylinder are placed inside the sidewall of the frame of a bearing frame. A cushion plate is arranged between the hydraulic cylinder piston cavity and the frame of the bearing frame. A protruding rod is fixedly connected to the end face of the piston cavity end of the hydraulic cylinder. The protruding rod is embedded into a groove arranged in the middle of one end face of the frame of the bearing frame. The other end of the frame of the bearing frame is open. The bearing frame is fixedly connected to a bracket. The invention also discloses a test method adopting the design verification load test system. The test system solves the problem that a conventional load test system is narrow in adaptation range and complex in operation and is limited by place. Through the connection of the bearing members and main bearing parts of the to-be-tested travelling block, a closed force transmissionstructure is formed. The verification of design verification load is realized by adjusting oil supply pressure of the hydraulic cylinder.
Description
technical field [0001] The invention belongs to the technical field of petroleum drilling and production equipment, and relates to a design verification load test system and a test method of a middle-pass traveling block. Background technique [0002] As a special motion compensation device, the drill string heave compensation system can effectively reduce the influence of the heave motion generated by the semi-submersible drilling platform, floating drilling platform and floating drilling ship on the bottom hole WOB and the life of the drilling tool under the action of waves. influences. In order to verify the design accuracy of the drill string compensation device, the design verification load test of the main bearing part must be carried out for the first set of traveling blocks according to the requirements of the design standard API SPEC 8C (fifth edition). The design verification load is 0.8×rated load value×safety coefficient, and not less than 2 times the rated load...
