The utility model provides a portable scaffold for construction engineering relates to the technical field of scaffold for construction engineering, include: first side lifting part, second side lifting part, lifting board part, first swing rod, first side lifting part and second side lifting part same structure, first side lifting part and second side lifting part symmetry distribution, first swing rod has two, two first swing rod one end respectively with first side lifting part L shaped support both sides are connected, two first swing rod other end respectively with two second swing rod one end rotation connection, this equipment can carry out simple folding, reduce the floor area, and this equipment below is equipped with universal wheel, can be convenient for manual arbitrary movement equipment, simultaneously, this equipment is equipped with protective net, prevents manual in the course of operation, because of inattentive drop, reduces the risk that personnel has the accident, this equipment can also carry out secondary lifting, utilizes simple structure to increase lifting height, has improved equipment application range.

This utility model discloses a fire truck hose and cable layout structure, including a fire truck and a drone, with the drone mounted on the upper part of the fire truck. A fire-extinguishing water spray pipe is installed on the drone, connected to the fire truck's water pump via a hose. The drone is connected to a DC power supply on the chassis at the bottom of the fire truck via a cable, with the drone receiving DC power from the chassis power supply. Only one positive conductor is installed in the cable. The hose includes an outer layer, a negative conductor, and an inner lining layer, with the negative conductor positioned between the outer and inner lining layers and braided together with the outer layer. This utility model removes the negative conductor from the cable and integrates it into the hose structure, reducing the cable diameter and weight, effectively increasing the drone's lifting height under a 400kg load. The flowing medium inside the hose continuously carries away heat from the negative conductor, avoiding overheating risks. Simultaneously, the braided copper conductor and polyester layer enhance the hose's compressive strength.
