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
The present invention relates to technical field of electric appliances, relate in particular to a kind of electrical installation of suitable portal crane walking.
Background technology
Current colector is current collector again, is a kind of electrical installation (the main electrical part that connects portal crane and slip road) of suitable portal crane walking.Along with engineering gets into the construction peak load conditions, portal crane is suitable for too frequent, and the collector damage frequency is high, former because: 1. current colector and being connected of slip be through carbon brush as bridge, carbon brush quick abrasion (replacing in 1 month 1 time); 2. the flexible scope of current colector is less can not alleviate the carbon brush wearing and tearing by actv.; 3. current colector only has the insulation outpost of the tax office one, causes the line short fault easily.Be necessary technical scheme of the prior art to be done further improvement for this reason,, improve the portal crane Occupation coefficient, guarantee to produce to remedy the deficiency of existing current colector technology to the problems referred to above.
Summary of the invention
The technical matters that the present invention will solve is: a kind of portal crane current collector is provided, can increases the service life.
The present invention solves the problems of the technologies described above the technical scheme of being taked to be: a kind of portal crane current collector is characterized in that: it comprises insulating base, expansion link, nylon insulation rod, traveling wheel and pulley base; Insulating base connects with the expansion link lower end, and nylon insulation rod lower end connects with the expansion link upper end, and nylon insulation rod upper end connects with the pulley base; Traveling wheel is connected on the pulley base through bearing, twines slip on the traveling wheel; The bearing termination links through copper lug and cable.
Press such scheme, described expansion link comprises pipe, round steel and stage clip; Pipe is fixed on the said insulating base; Described insulating base is provided with aperture, and round steel is enclosed within the pipe and passes aperture, and compression spring sleeve is outside round steel; There is screw thread the round steel bottom and is connected with nut, and the round steel top connects with described nylon insulation rod; The nylon insulation rod is the cylindricality insulation rod of two joint different-diameters up and down, and the diameter of lower end cylindricality insulation rod is less than the internal diameter of pipe, and the diameter of upper end cylindricality insulation rod is greater than the external diameter of pipe.
Press such scheme, described insulating base is made up of metal base plate and the insulation leg that is connected on the metal base plate.
Press such scheme, described metal base plate is a steel plate; Described insulation leg is 4 porcelain insulators; Porcelain insulator and steel plate Bolt Connection.
Principle of work of the present invention is: expansion link is regulated the flexible scope of current colector through stage clip and round steel; Replaced common current collector to rely on the carbon brush walking with traveling wheel; The bearing that connects traveling wheel and pulley base directly feeds back to gauntry crane car owner motor through the copper lug connecting cable with electricity, makes whole portal crane and current colector be integrally formed; Adopt nylon insulation rod and insulating base, form two insulated barriers.
Beneficial effect of the present invention is: 1, change the connection mode of current colector and slip, reduce wearing and tearing, increase the service life; 2, use expansion link instead, flexible scope increases; 3, have two insulated barriers, avoid the line short fault, improve safety performance.
