Abstract

The invention discloses a chain dig device of self-propelled submarine cable embed device, whose compression arm is box covered by chain, front end is pipe inserted into rotational base to form a rotational shaft. Wherein, the rotational base via connection plate is mounted on the body of embed device; the inside hydraulic motor is connected to the chain wheel of dig chain; a caterpillar steel plate with cutting teeth is mounted on the chain; one end of compression hydraulic cylinder is mounted on the frame of embed device while another end is connected to the pipe structure of compression arm; a chain tension device is mounted inside the free arm of compression arm; the lower support is mounted above the compression arm while its one end is connected with one end of compression arm; the compressor is U-shape section frame via the side hinge shaft hinged with compression arm and above the lower support; and one end of open cylinder is hinged with compression arm while another end mounted on the side hinged shaft. The invention apply exchange with simple structure, lower cost and the application in self-propelled or floating self-propelled submarine cable embed device.

Description

technical field [0001] The invention relates to a digging tool, in particular to a chain digging tool for a self-propelled submarine cable laying machine. Background technique [0002] The rapid development of the global communication industry needs to bury a large number of cables and optical cables (submarine cables) on the seabed. Early cables crossed the seabed and were placed directly on the seabed without burying. However, due to the increase in marine vessels and fishing activities, since the 1950s, in order to prevent damage to transoceanic submarine cables, people began to develop and develop cable burying technology. In order to adapt to the continuous increase of operating water depth and burial depth, self-propelled submarine cable embedding machines with crawler belts as the walking mechanism appeared in the 1990s. When laying cables on the hard sandy seabed with a shear strength of 25-400kPa, the self-propelled embedding machine generally needs to be equipped...
