The invention discloses an offshore platform deck piece lifting point generation method, which belongs to the technical field of ship and ocean engineering, is used for generating lifting points of an offshore platform deck piece, and comprises the following steps: calculating the gravity center of the deck piece, selecting a single crane or double cranes according to the weight of the deck piece, and selecting the lifting points of the single crane by taking the gravity center as a circle center. Constructing a lifting point circle by taking the calibrated distance set as a radius; for double-crane lifting point selection, a deck piece is divided into two areas, the center of a lifting point circle is arranged in each area, and the lifting point circle is constructed with the calibrated distance set as the radius; and the lifting point circles and the rod pieces form intersection points, four lifting points are selected for each lifting point circle every time to serve as candidates for traversal, and through lifting point reasonability judgment, deck piece lifting points are finally generated. According to the method, the lifting point circle is constructed, candidate points are traversed, and project requirements can be quickly responded; through an auxiliary positioning mechanism, it is ensured that the method can still be effectively applied when facing various complex and non-standard deck sheet structures, and the robustness of the method is improved.

This invention relates to the field of civil engineering technology, and provides a double-layer thin-walled pressurized column component, comprising an outer column shell, an inner cylinder, and a pressurization container. The outer column shell has a hollow structure; the inner cylinder is a cylindrical structure with open ends, disposed inside the outer column shell, with its axis parallel to the axis of the outer column shell, and a gap between the outer side wall of the inner cylinder and the inner side wall of the outer column shell; the pressurization container is disposed inside the inner cylinder, and is used to fill a pressure medium and expands and deforms as the internal pressure of the pressure medium increases, thereby generating compressive force on both ends of the outer column shell. This design solves the problems in related technologies where pressure-bearing components are prone to bending or buckling instability when bearing external pressure, and the low material utilization efficiency caused by the cylinder wall of the pressure-bearing component simultaneously bearing axial and circumferential stresses.

The fuel tank comprises a fuel tank body and a cylindrical beam, a concave area is arranged on the side of the rear portion of the fuel tank body and provided with a first buffer slope, the cylindrical beam is connected to the upper portion of the rear portion of the fuel tank body, and the two ends of the cylindrical beam are located on the two sides of the fuel tank body. The hydraulic oil tank is installed in the sunken area and comprises a hydraulic oil tank body and a circular tube beam, the circular tube beam is arranged above the rear portion of the hydraulic oil tank body, and the cylindrical beam is inserted into the circular tube beam; a second buffering inclined face is arranged on the rear portion of the hydraulic oil tank body, and the second buffering inclined face and the first buffering inclined face are opposite in position. The invention discloses a hybrid power mine truck and an installation method of a combined oil tank. Space can be reserved for arrangement of the power battery of the hybrid power mine truck, and overall arrangement and installation of the fuel tank and the hydraulic oil tank are achieved.

This utility model discloses a convection-type windproof photovoltaic support, including a mounting frame with multiple connecting seats fixedly mounted on it. A photovoltaic panel is disposed on one side of each connecting seat. The photovoltaic panel is connected to the connecting seat via a telescopic adjustment device. Multiple photovoltaic panels are positioned facing or away from the center of the mounting frame, and are aligned or dispersed. The mounting frame includes an outer ring and an inner ring. A connecting plate is fixedly connected to the corner of the outer and inner rings. Multiple vertical plates are fixedly disposed at the bottom of the connecting plates, and a base plate is fixedly disposed at the bottom of each vertical plate. The connecting seats are fixedly mounted on the inner ring, connecting plates, and outer ring. When the photovoltaic panels are dispersed, they provide convection and windproof protection, allowing wind to pass through the area between the photovoltaic panels, reducing the overall stress on the support and preventing significant stress on large areas of the photovoltaic panels.

This utility model discloses a lightweight, high-strength aluminum alloy bicycle frame, belonging to the field of bicycle frames. The device includes a head tube, front fork, frame, seat tube, rotating bushing, down tube, and rear fork. The front fork is mounted at the bottom of the head tube. One end of the frame is welded to the head tube, and the other end is welded to the seat tube. A rotating bushing is welded to the bottom of the seat tube. One end of the down tube is welded to the rotating bushing, and the other end is welded to the head tube. Symmetrical movable support blocks are arranged on the outer periphery of the seat tube. Compared to traditional bicycle frame devices, the triangular design of the rear fork effectively disperses various forces generated during riding, allowing the rear fork to maintain a stable structure even under complex road conditions. Simultaneously, the rear fork transmits vibrations to the shock absorber through the movable support blocks. The shock absorber uses the pressure of sealed gas to achieve shock absorption, effectively reducing vibration transmission to the rider's body and improving riding comfort.

The present invention provides a mobile liquid hydrogen tank container, which includes an inner container and an outer container arranged outside the inner container. A plurality of sliding support structures are arranged between the inner container and the outer container in the circumferential direction. The sliding support structures are used to support the inner container and enable the inner container to slide along the axial direction relative to the outer container when thermal stress is generated in the mobile liquid hydrogen tank container. By setting the sliding support structure between the inner container and the outer container in a multi-point connection manner in the circumferential direction, the present invention reduces the contact area between the inner container and the outer container on the basis of supporting the inner container, achieves the purpose of reducing heat leakage, and the inner container is well stressed, which can improve the safety of the inner container.

This invention discloses a scaffold connector for easy disassembly of tall formwork structures, comprising uprights, horizontal bars, vertical diagonal bars, a movable hinge plate, and a connecting plate. The uprights and horizontal bars are connected by the connecting plate. The front end of the connecting plate has six connecting teeth, and the inner edge of the connecting plate has three V-shaped connecting hooks. The front end of the horizontal bar includes six horizontal bar protrusions and three diamond-shaped connecting hooks. The horizontal bar protrusions connect with the connecting teeth, and the diamond-shaped connecting hooks connect with the V-shaped connecting hooks. The movable hinge plate is connected to the horizontal bar, and its upper and lower ends are threaded to the diagonal bars. This scaffold connector, through the rational arrangement of the structure of each component, reduces the local pressure on the connecting plate, and the connecting plate and the horizontal bar can be quickly connected or disassembled using a simple push-pull engagement.
