Forklift equipment special for flammable ice on surface of sea floor

Abstract

The invention belongs to the field of mining equipment for flammable ice on the surfaces of sea floors, and particularly relates to forklift equipment special for flammable ice on the surface of a sea floor. The forklift equipment comprises a forklift body, two driving wheels and two driven wheels, wherein the two driving wheels are rotationally installed on the two sides of the front portion of the forklift body, and the two driven wheels are rotationally installed on the two sides of the rear portion of the forklift body. Two driving motors used for driving the two rotary wheels are installed on the forklift body. The front end of the forklift body is connected with a bucket. A rear extending part is arranged on the upper portion of the rear end of the bucket. A strip-shaped opening in the left-right direction of the bucket is formed in the lower end of the rear extending part. A conveying belt which is arranged in the left-right direction of the bucket is installed on the lower portion, corresponding to the lower portion of the strip-shaped opening, of the rear extending part. The bucket is used for lifting the crushed solid flammable ice, so that the solid flammable ice is transferred onto the conveying belt. Compared with the other modes, the action ranges of all executive components are small, so that the situation that the solid flammable ice is decomposed in the process of being conveyed to a flammable ice mining well is avoided.

Description

Technical field [0001] The invention belongs to the field of seabed combustible ice mining equipment, and specifically relates to a special forklift equipment for seabed surface combustible ice. Background technique [0002] In the process of mining combustible ice on the seafloor surface, it is necessary to break the combustible ice into small pieces and then load it into a sealed tank and then transport it to the sea. So far, no public literature has found that it is suitable for long-term combustible ice mining on the seafloor surface. device of. As a mechanical device working in deep water, its executive components generally use motors as driving forces. [0003] On the other hand, the document number CN102195387B discloses a sealing structure of a submersible pump, which includes a conventional structure of a hydraulic pump driven by a motor driven by a rotor and a stator with embedded windings through its rotating shaft, and located at the outermost Layer of protective jack...

Problems solved by technology

——In this patent solution, since the metal seal isolation shield is not completely closed only at the lower end and the shaft seal of the motor, the submersible pump must keep the motor at the upper liquid pump to ensure its sealing effect, so in use Generally, it is necessary to use fixing parts to fix the submersible pump in a stable position before it can be used. When this type of submersible pump is used on a deep seabed (for example, when the depth of combustible ice is mined on the seabed, the depth exceeds 300 meters), the fixing of this type of submersible pump It is very difficult, and it is difficult to achieve the effect of maintaining the sealing performance for a long time with ordinary submersible pumps.
