This utility model discloses a photovoltaic bracket suspension support structure, mainly comprising triangular support stabilizing units. Each triangular support stabilizing unit consists of two equally sized right-angled triangular supports symmetrically arranged on the left and right sides of a column. The right-angled triangular supports are composed of a column, a crossbeam, and diagonal braces, with the column and crossbeam serving as the right-angled sides and the diagonal braces as the hypotenuses. The two right-angled triangular supports share a single column. This utility model offers advantages such as economy and safety, high construction efficiency, and rapid component installation. It effectively solves problems such as difficulty in installing photovoltaic modules in fish-solar hybrid projects, agricultural-solar hybrid projects, and projects with excessively high ground clearance, which often result in low efficiency, long construction periods, and uneconomical costs.

The utility model provides a kind of applied to the auxiliary erecting tool of cable erection, it is related to cable erection technical field, including trolley, the top of trolley is connected with auxiliary lifting assembly, the auxiliary lifting assembly includes two groups of fixed support.The utility model in when erecting scene space is smaller, cannot use lift truck to carry out the erection of cable, cable can be rolled to trolley by uphill board, after then, servo motor is started to drive rotating rod rotation, to make two groups of unidirectional screw rod rotate simultaneously, further by the mode of screw rotation drives cable to ascend, trolley is pushed to the front of target placing rack, after adjusting cable position makes it with placing rack accurate alignment, switch servo motor is positive rotation mode, by positive engagement transmission makes unidirectional screw rod drive hanger steady decline, until cable and placing rack are completely contacted, i.

This utility model relates to the field of insulator technology, specifically an insulator for overhead power transmission and distribution lines, comprising: an insulator body, an insulator platform fixedly mounted on the upper end of the insulator body, a cover plate rotatably mounted on the mounting platform, and a fixing component and an auxiliary component mounted on the mounting platform for mounting the power transmission and distribution line body; by inserting the power transmission and distribution line body into the mounting groove and placing it on the arc surface of the arc-shaped pad, rotating the cover plate to press the power transmission and distribution line body so that the power transmission and distribution line body fits against the anti-slip ridges on the arc surface of the arc-shaped pad, while the rotating column and the lever plate are inserted into the straight groove, and then rotating the lever plate causes the lever plate to engage with the protruding plate to limit the cover plate, the compressed spring returns to its original position and pushes the limit plate to move, causing the positioning plate to move upward so that its end wall engages with the rotating plate, thereby fixing the position of the lever plate and realizing the stable mounting of the power transmission and distribution line body on the insulator body for overhead power transmission and distribution lines. The operation is simple and quick, without the need for auxiliary tools, thus improving the efficiency of power transmission and distribution line erection.

The present application relates to a kind of slice assembly type variable cross-section box girder cantilever crane and hoisting method, crane includes support system, walking system and hoisting system;Walking system includes two tracks beams anchored in the beam surface two sides, the support system includes two diamond truss pieces, the lower longitudinal beam of two truss pieces is temporarily anchored on track beam, hoisting system includes two mobile cross beams, two mobile cross beams are supported on the upper longitudinal beam of two support pieces and can slide along the upper longitudinal beam, two mobile cross beams are respectively equipped with two winches that can slide along mobile cross beam.By hoisting system hoisting the each board unit of box girder section and splicing into complete section, after one section hoisting is completed, support system moves forward and hoists next section.The crane structure of the present application is simple, small in size, light in weight, and has good applicability for slice assembly type box girder section assembly.

This utility model discloses a cable cutting device for electromechanical installation engineering, including a workbench. A base is provided at the bottom of the workbench, and a first support plate is provided on the upper surface of the workbench. A lifting cylinder is provided on the top of the first support plate, and a first limiting post is provided at the output end of the lifting cylinder. A transmission rod is provided on the side of the first limiting post, and a first cutting head is provided at the bottom of the transmission rod. Two support seats corresponding to the first cutting head are provided on the upper surface of the workbench. An arc-shaped groove is formed on the top of each support seat, and tensioning components are provided on both sides of each support seat. This application includes a first cutting head and a second cutting head. The first cutting head can cut the cable, and the second cutting head simultaneously cuts the cable outer shell, separating the cable outer shell from the main cable at the cable connection point. This facilitates subsequent cable splicing and improves the efficiency of cable laying.

The application belongs to the technical field of scaffolds, and particularly relates to a disc buckle type scaffold. The overall structure at the two ends of the horizontal rod is arranged at the upper end of the connecting disc, the unilateral stress concentration problem caused by the fact that the construction load directly acts on the local area of the connecting disc in the traditional scaffold is changed, and therefore the stress uniformity and structural durability of the connecting disc are effectively improved. The end of the horizontal rod is provided with a mounting portion with a locking hole, the locking hole can be matched with the locking area on the vertical rod, the displacement or rotation of the horizontal rod in the use process is effectively limited, and the stable connection between the horizontal rod and the vertical rod is realized. In addition, at least one group of horizontal rods which are arranged perpendicularly to each other in the horizontal plane are connected on the same vertical rod, the vertical rod can form a spatial stable structure with at least two surrounding vertical rods through the structural design, the overall structural stability requirement can be met without being connected with all the vertical rods in four directions, the safety is ensured, and the installation and dismounting efficiency of the scaffold is significantly improved.
