4results about How to "Flexible and convenient layout" patented technology

The invention discloses a cantilever type underwater towed navigation body laying and recovery device which comprises a power distribution control cabinet and further comprises an installation frame, the lower portion of the installation frame is connected to a ship deck, and a base plate is detachably installed at one end of the installation frame. The cable winch mechanism is mounted at a non-cantilever end in the mounting frame; the bracket assembly is mounted in the mounting frame close to the cantilever end; the guide assembly is connected above the mounting frame in a sliding manner; the linear motion mechanism is arranged above the mounting frame and is connected with the guide assembly; the adjusting assembly is mounted on one side of the mounting frame and is in transmission connection with the linear motion mechanism; wherein a dragging cable of the cable winch mechanism is connected with the underwater dragging navigation body after passing through the guide assembly. The device is simple and compact in structure and convenient to disassemble and assemble, and the risk of collision between the towed navigation body and a ship deck and related equipment is reduced by adopting outboard lowering and withdrawing; and the base plate can play a role in buffering and protecting the bottom of the underwater towed navigation body when the underwater towed navigation body is supported.

The present application belongs to the technical field of refrigeration and low temperature engineering, and discloses a throttling refrigerator, which comprises a capillary bundle and a shell, the capillary bundle comprises a plurality of capillary tubes filled and arranged in the shell, the end portions of the plurality of capillary tubes are flush arranged, the first end of the capillary bundle is a working medium inlet, the second end of the capillary bundle extends to the bottom of the shell and has an expansion gap with the bottom of the shell, the plurality of capillary tubes have a backflow gap therebetween, and a backflow outlet is arranged on the side wall of the shell close to the first end of the capillary bundle. The capillary bundle is arranged as a fluid throttling channel, the arrangement of the capillary bundle is flexible and convenient, the setting process is simple, the three-dimensional space of the shell can be fully utilized, the space utilization rate of the shell is improved, the capillary bundle can be arranged more, the overall flow of the fluid channel is increased, the channel is composed of a plurality of capillary tubes, the refrigerator has larger flow and refrigerating capacity, and the refrigeration performance is improved.

The utility model discloses a shield tunneling machine segment crane limiting device which comprises a stand column, a cross beam, a deflector rod, a limiting switch assembly, a segment machine supporting beam, a segment machine rotation moving frame, a segment crane, a cross-shaped limiting switch and a segment machine working platform, and the segment machine working platform is fixed to the segment machine rotation moving frame and moves along with the segment machine rotation moving frame; the cross beam is a rectangular steel pipe, an open groove is formed in the middle of one wide side of the cross beam in the length direction, the open groove of the cross beam is upwards welded to the tops of the stand columns, the two deflector rods are perpendicularly welded to the same side faces of the two ends of the cross beam respectively, and the limiting switch assembly is arranged in the middle of the cross beam in the length direction. The bottom ends of the stand columns are welded to a segment machine working platform and located at the two ends of a segment crane walking track or fixed to the limiting position. And the cross-shaped limit switch is arranged on a duct piece crane wheel box of a traveling device of the duct piece crane. The device can avoid the risks of equipment damage, extrusion, falling impact and the like caused by misoperation, and is simple, compact and flexible and convenient to arrange.

The utility model discloses an improved underwater towed navigation body laying and recovery device which comprises a power distribution control cabinet and further comprises an installation frame, and the lower portion of the installation frame is connected to a ship deck. The cable winch mechanism is mounted at a non-cantilever end in the mounting frame; the bracket assembly is mounted in the mounting frame close to the cantilever end; the guide assembly is connected above the mounting frame in a sliding manner; the linear motion mechanism is arranged above the mounting frame and is connected with the guide assembly; the adjusting assembly is mounted on one side of the mounting frame and is in transmission connection with the linear motion mechanism; wherein a dragging cable of the cable winch mechanism is connected with the underwater dragging navigation body after passing through the guide assembly. According to the utility model, outboard lowering and withdrawing are adopted, so that the collision risk of the towed navigation body with a ship deck and related equipment is reduced; and meanwhile, the occupied space is small, good universality is achieved, and the task requirement for flexibly laying and recovering the underwater towed navigation body on small and medium-sized ships with limited shipborne space can be met.
