Portal crane current collector

A technology of gantry cranes and collectors, which is applied in the direction of load hanging components, transportation and packaging, etc., and can solve problems such as the small expansion and contraction range of collectors, which cannot effectively alleviate the wear of carbon brushes, the high frequency of collector damage, and short-circuit faults in lines. Achieve the effect of increasing the telescopic range, prolonging the service life, and avoiding short-circuit faults

Embodiment Construction

[0014] figure 1 It is a structural schematic diagram of an embodiment of the present invention, figure 2 for figure 1 A-A sectional view of, image 3 for figure 1 The B-B sectional view, Figure 4 for figure 1 C-C sectional view of C-C, including insulating base, telescopic rod, nylon insulating rod, walking pulley 8 and pulley base 9.

[0015] The insulating base consists of a 2mm thick steel plate 10 and an insulating porcelain vase 7 connected on the steel plate 10, and the insulating porcelain vase 7 is connected with the steel plate 10 by bolts to play an insulating role.

[0016] The pulley base 9 is U-shaped, and the walking pulley 8 is connected in the pulley base 9 through a bearing, and the sliding wire is wound on the walking pulley 8; the bearing end has a 25mm thread, and is connected with the cable through the copper nose 6. The walking pulley is a copper wheel, which has a 2mm cap on the surface after lathe machining to reduce the frictional resistance of...

Abstract

The invention provides a portal crane current collector, which is characterized by comprising an insulated base, a telescopic bar, a nylon insulated rod, a traveling pulley and a pulley base, wherein the insulated base is connected with the lower end of the telescopic bar; the lower end of the nylon insulated rod is connected with the upper end of the telescopic bar, and the upper end of the nylon insulated rod is connected with the pulley base; the pulley base is U-shaped, and the travelling pulley is connected in the pulley base via a bearing and is wound with slide wires; the end socket of the bearing is connected with a cable via a copper pig tail; the telescopic bar is used for adjusting the telescopic range of the current collector by means of a pressure spring and a round steel; the travelling pulley replaces a common current collector which depends on a carbon brush to travel; the bearing connecting the travelling pulley with the pulley base is connected with the cable via the copper pig tail so as to directly feedback electricity to the main motor of the portal crane, thus integrating the entire portal crane with the current collector into a whole; and the nylon insulated rod and the insulated base form two insulated barriers, thus preventing circuits from shorted faults and improving safety performance.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to an electrical device suitable for traveling by a gantry crane. Background technique [0002] The current collector, also known as the receiver, is an electrical device suitable for the traveling of the gantry crane (the main electrical device connecting the gantry crane and the slideway). As the project enters the peak period of construction, the gantry crane is used too frequently, and the frequency of collector damage is high. The reasons are: 1. The connection between the collector and the sliding wire is through the carbon brush as a bridge, and the carbon brush wears quickly (replace once a month. ); 2. The range of expansion and contraction of the collector is small and cannot effectively alleviate the wear of the carbon brush; 3. The collector has only one insulation barrier, which is likely to cause a short circuit fault. For this reason, it is necessary to...
