Single-stage safety wire contact device installation project

The installation of the trolley line device mainly includes the fixing of the trolley line on the insulator, the production and installation of the trolley line retractor, and the production and installation of the maintenance section device.

Item Name Slide Line Item Feature 1 Name; 2 Model; 3 Specification; 4 Material Measurement Unit m

Engineering quantity calculation rule Calculate the single-phase length of the project according to the design diagram. Project content 1 Sliding line bracket production, installation, brushing oil; 2 Sliding line installation; 3 Tensioning device and hanging supporter production, installation (1) Project name slide Contact line: can be made of angle steel, flat steel, round steel, copper car wire and so on. However, these types of trolley wires consume a lot of energy. Now, safe and energy-saving slide wire devices have been promoted.

(II) Item Characteristics Slide wire tensioning device: It can be used to adjust the expansion and contraction of the circular slide wire. General requirements for long contact line within 25m, adjustment distance should not be less than 100mm; more than 25m, the adjustment distance should not be less than 200mm.

Slide wire bracket: There are many forms, generally based on the design requirements or the actual needs of the site, use one of the current national standards map bracket or self-processing. During the production, the size of the processing should be carefully checked. If necessary, the actual size of the building can be measured at the construction site, and a sketch can be drawn and processed according to the figure. The E-shaped bracket is the bracket most commonly used for angle steel wire contact and is welded with angle steel. The bracket is fixed with studs.

Slide wire retractor: It is a kind of temperature compensation device. When the trolley line crosses the building expansion joint or the length exceeds 50m, a retractor should be installed to accommodate the settlement and temperature changes of the building. Between the two angle rails of the retractor, 10 to 20 should be left

The gap of mm, the contact line on both sides of the clearance should be processed to be smooth, the contact surface is installed on the same level, and the difference between the two ends should not be greater than 1mm.

Seated tram insulator holder: The lower end of the insulator is fixed on the angle bracket by a nut, and the upper end is equipped with inner and outer clamps for fixing the trolley wire. The angle specification of the outer splint is the same as that of the angle wire of the trolley wire, and the specification of the inner splint angle steel is smaller than that of the outer splint angle steel.

Hanging type contact line: It is a type of suspended trolley line. Hanging type wire contact supports are generally made of iron, made of angle steel or other steel, and are fixed with studs.

(III) Rules for Calculating Engineering Volume (None)

(IV) Project content Crane trolley line: The crane is a common lifting device in the factory workshop. The trolley line and moving cable are the supporting facilities for the crane. The cranes used in the workshop include bridge cranes, single-girder suspension cranes and electric hoists. In the workshop, in order to supply the crane with power, the trolley wire should be laid along the crane girder. The power supply to the trolley trolley line is generally led from the main power line to the branch circuit and is powered by the iron shell switch. The collector on the crane is then powered by the trolley line. The power switch, wire and trolley wire are not crane equipment and need special design and construction. This is one of the contents of workshop power engineering.

Crane trolleys are divided into bare skid line and safety skid line.

(1) Bare installation trolley wire installation. The bare skid line used by the crane can be made of angle steel, flat steel or round steel (round bar) depending on the type of crane. The trolley line is generally arranged on the opposite side of the driver's cab of the crane; if it is arranged on the side of the driver's cab, when the upper and lower cabs of the staff are in danger of touching the trolley line, they must be provided with barrier protection. The trolley wires for electric hoists and hanging cranes are generally mounted on brackets on I-beam rails.

   Beam roll forming machine is used with upright roll forming machine, it can produce various types pillars for warehouse storage or supermarket shelves. The production speed can be adjustable. The quantity, punching and cutting length be automatically controlled by the PLC system.
