Embodiment Construction
[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0024] Such as Figure 1 to Figure 4 A locking device for preventing slippage and overturning of the drilling floor of a self-elevating drilling platform is shown, which includes two locking claws 10 symmetrically installed on both sides of the bottom of the drilling floor support 11, and each locking claw 10 rotates Bearing pin 7 is hinged on the drill floor support 11, and the two ends of rotating pin shaft 7 are provided with adjusting nut 9, and the length of rotating pin shaft 7 is greater than the width of locking claw 10 tops. A connection plate 8 is provided at the joint between the rotating pin shaft 7 and the outside of the drill floor support 11 . Locking pawl 10 is provided with several locking pins 14 on the side wall bottom facing cantilever track support beam 13, and the spacing between two adjacent locking pins 14 is the same as the lock on t...

The invention discloses a locking device for preventing slippage and overturning of the drill floor of a self-elevating drilling platform. Hinged on the support of the drill floor, the two ends of the rotating pin shaft are provided with adjusting nuts, and the locking claws are provided with several locking pins on the lower part of the side wall facing the cantilever beam track support beam. The distance between two adjacent locking pins is the same as that of the cantilever The spacing of the locking pin holes on the stiffener plates on both sides of the top of the beam track support beam is consistent, and the shape and specification of the locking pins are compatible with the locking pin holes. In the present invention, the locking pin on the locking pawl is engaged with or disengaged from the locking pin hole on the stiffener plate of the cantilever beam track support beam, and the locking pin and the locking pin hole are matched to provide a force against slipping and overturning , so that the drill floor can be locked at any position of the cantilever beam track support beam during normal operation, so as to prevent the drill floor from slipping or overturning. The locking / unlocking operation is convenient, time-saving and labor-saving, and has high reliability.
Description
technical field [0001] The invention relates to the technical field of offshore drilling platform equipment, in particular to a locking device for preventing slippage and overturning of a self-elevating drilling platform drill floor. Background technique [0002] The jack-up drilling platform is an important equipment for offshore oil exploration and development. Compared with the traditional cantilever beam, the drilling floor and the cantilever beam are separated. In order to meet the requirement of drilling multiple oil wells at the same site, the drill floor of the jack-up drilling platform needs to be able to move horizontally on the cantilever beam. During the actual drilling operation and towing process, due to the influence of factors such as wind force in the operation area, vibration of the rig floor, and platform pitch and roll, the rig floor will slip or capsize on the track support beam, which will lead to major safety accidents . Therefore, the jack-up rig ne...
