Description

Technical Field

[0001] This application relates to the technical field of subsea trenchers, and particularly to a frame structure of a subsea trenching device. Background Art

[0002] A subsea trencher is a special device dedicated to trench digging operations on the seabed. It plays an important role in engineering projects such as subsea oil and gas development, subsea cable laying, and subsea communication lines. According to the form of the impact force generated on the soil, subsea trenchers can be divided into types such as hydraulic jet trenchers, mechanical trenchers, and plow trenchers. Among them, hydraulic jet trenchers use high-pressure water jets to disperse the soil to form a trench shape, mechanical trenchers directly excavate through mechanical devices, and plow trenchers are similar to plows in farmland and cut a trench by sliding on the seabed.

[0003] A prior patent (publication number: CN206015761U) discloses a crawler-type subsea trenching device, including a machine shell, a digging shovel, and a bucket. An engine is arranged on the lower left side inside the machine shell, two front and rear drive wheels are symmetrically arranged on both sides of the machine shell, a high-power motor is arranged on the upper left side inside the machine shell, a transmission belt is connected between the output end of the high-power motor and the rotating shaft, a concentric rotating shaft is fixedly arranged around the middle of the rotating shaft, a circle of digging shovels is connected around the concentric rotating shaft, a bucket is arranged at the central position of the bottom of the machine shell, a water pumping device is connected to the upper end of the bucket, a horizontally placed transverse sewage outlet is connected to the water outlet end of the water pumping device, and a tail water outlet is arranged at the connection between the output end of the water pumping device and the transverse sewage outlet. A control unit is arranged on the lower right side inside the machine shell. The utility model improves the excavation efficiency by using the digging shovel in cooperation with the bucket, and adds a water pumping device in cooperation with the sewage pipe for sewage discharge, avoiding the excavated soil from filling the gully again.

[0004] During the use of the above document, the overall lack of stability on the slope makes it impossible to transfer the center of gravity of the device, which will cause the overall device to be unstable when working on the slope and is inconvenient to use. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, this application provides a frame structure of a subsea trenching device, which has the advantages of transferring the center of gravity and improving stability, and solves the problems raised in the background art.

[0006] To achieve the above object, the present application provides the following technical solutions: A frame structure of a subsea trenching device, including a body. A set of swing grooves are provided on both the left and right sides of the body. A rotating column is rotatably connected between each set of swing grooves. Swing counterweights are fixedly connected to the outer surfaces of the two rotating columns. A plurality of swing counterweights are located in the swing grooves adjacent to them. Swing frames are hinged to both the left and right sides of the body. Driving devices are installed at the ends of the two swing frames away from each other. Driving tracks are installed on the outer surfaces of the two driving devices.

[0007] Through the above solution, by installing a plurality of swing counterweights, when the body works on a slope, the center of gravity of the body can be transferred through the cooperation of the swing counterweights.

[0008] Further, two driving motors are installed on the front surface of the body. The output ends of the two driving motors are fixedly connected to the rotating columns adjacent to them.

[0009] Through the above solution, installing the driving motors can drive the rotation of the rotating columns, enabling the rotating columns to drive the swing counterweights to approach or move away from the center of the body.

[0010] Further, a plurality of damping buffers are hinged to both the left and right sides of the body. The other ends of the plurality of damping buffers are hinged to the swing frames adjacent to them.

[0011] Through the above solution, installing a plurality of damping buffers can buffer the pressure when the swing frames swing, enabling the driving tracks to remain in contact with the ground.

[0012] Further, the body is treated with rust prevention.

[0013] Through the above solution, treating the body with rust prevention can improve the overall corrosion resistance, thereby extending the overall service life.

[0014] Further, a plurality of the swing counterweights are in the shape of cams.

[0015] Through the above solution, setting the swing counterweights in the shape of cams can facilitate the transfer of the overall center, enabling the body to work stably on the slope.

[0016] Further, fixing members are installed on the inner wall of the body. An expansion link is installed on the bottom surface of the fixing member. A trenching device is installed at the bottom end of the expansion link.

[0017] Through the above solution, installing the expansion link can control the height of the trenching device, thereby enabling the adjustment of the trenching depth.

[0018] Further, a gyroscope is installed on the inner wall of the body.

[0019] Through the above solution, installing a gyroscope can detect the angle of the body and facilitate the adjustment of the inclination of the body.

[0020] Furthermore, a steering platform is rotatably connected to the upper surface of the body, and a plurality of monitoring devices and a plurality of lighting devices are installed on the outer surface of the steering platform.

[0021] Through the above solution, installing a camera rotation can facilitate the observation of the ground, and installing a lighting device can facilitate the operation of the body at night.

[0022] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0023] For the frame structure of the subsea trenching device, by installing a plurality of swinging counterweights, when the body works on a slope, the center of gravity of the body can be transferred through the cooperation of the swinging counterweights, and the friction with the slope can be increased in cooperation with the crawler, so as to improve the stability of the body when working on the slope. At the same time, it still has high structural strength when moving on the rugged seabed, improving the overall practicability. Description of the Drawings

[0033] Please refer to Figure 1 、 Figure 2 and Figure 4 Multiple swing counterweights 4 are in the shape of cams.
