Production of power sliding contact line for electric hoist bridge crane

DHGTJT-1000A power sliding contact wire, safety sliding contact wire is a new type of mobile power supply device that gradually replaces old exposed angle iron and copper bar sliding contact wire with its superior insulation, safety, temperature resistance, vibration resistance, energy saving and other performance. The safety sliding contact wire is composed of smooth and flat T2 copper bars or aluminum profiles embedded with wear-resistant conductors filled in engineering plastic pipes or groove plates as the carrier fluid, combined into a transmission conduit with an open groove under the conduit to facilitate the operation of the current collector. The high wear-resistant copper based graphite brush of the current collector guides the electric force to the working electrical device.

The structure of the safety sliding contact line is diverse, but the general principle is as follows: mobile devices need to change positions from time to time due to their movement, and at each different position, the mobile device must be able to obtain power at any time, otherwise it cannot continue to move. At this time, the safety sliding contact line emerged by laying several conductors in parallel along the running track of the mobile device and connecting them to the power supply. On mobile devices, there is also a collector installed that can draw electricity from conductors.

DHGTJT-1000A power sliding contact line, single-stage sliding contact line is a new type of power supply system for feeding mobile mechanical equipment. The conductor is a special formula high-quality aluminum alloy profile, and the outer sheath is made of special polyvinyl chloride material, which plays a safe role in rain, dust, snow, and electric shock prevention. Simple in structure and easy to install and maintain, it is widely used as a power supply line for mobile equipment in mining, metallurgy, chemical industry, machinery, docks, freight yards, and other fields.

Single level sliding contact wire components: 1. Collector; The main device for picking up electrical energy on the collector side in the sliding contact line system, which directly conducts electrical energy to the electrical appliances through the sliding contact between the collector brush and the guide rail, thus achieving the mobile power supply of the system. The current collector consists of two parts: a mechanical tension device and a current collector brush that directly slides in contact with the guide rail. 2. Maintenance section; Mainly used for maintenance of sliding contact lines. 3. Temperature compensation section; Also known as the thermal expansion compensation section, it is used to compensate for changes in wire length caused by temperature fluctuations. 4. Hanging rack; A device used to fix sliding contact wires. 5. End sheath; Protect the safety and service life of the sliding contact wire. 6. Fixed frame; A bracket used to fix and stabilize sliding contact wires.

The hoist double beam crane uses an electric hoist as the lifting mechanism, and the bridge adopts a semi inclined rail box beam with conductive cables. The main beam and end beam are connected by detachable bolts. The gourd double beam crane has the advantages of compact external dimensions, low building clearance height, light weight, small volume, low wheel pressure, and simple structure. It is also easy to install, use, maintain, and transport, making it a new type of bridge crane. Suitable for various occasions such as workshops, logistics parks, factories, metallurgical manufacturing, mechanical processing, etc.
