The safe power supply system comprises high-altitude bare sliding wires, sliding wire brackets, current collectors, a reversing pulley, a heavy hammer block and a limiting switch, wherein a plurality of high-altitude bare sliding wires (2) respectively pass through pulleys in a plurality of pulley assemblies (3) of the current collectors and then placed into V-shaped sliding wire limiting devices (12) fixed on the sliding wire brackets (10) below, one ends of the high-altitude bare sliding wires (2) are connected with an insulator (1), the other end of the insulator (1) is fixed on a building, the other ends of the high-altitude bare sliding wires (2) are connected with an insulator (4), the other end of the insulator (4) is connected with one end of a steel wire rope (6), the other end of the steel wire rope (6) passes by the reversing pulley (5) and then is connected with the upper part of the heavy hammer block (7), and the reversing pulley (5) is fixed on the building. The utility model relates to the safe power supply system for the outdoor high-altitude sliding contact wire of the gantry crane, which is large in spacing distance among the sliding wire brackets, small in investment cost, convenient to install and maintain, safe and reliable to use, and worthy of promotion.
Description
Technical field
The invention discloses a kind of high-altitude power supply system of sliding contact line, be in particular the outdoor high-altitude of transfer crane trolley safe power supply system, belong to high-altitude slide wire power supply technical field.
Background technology
The high-altitude power supply system of sliding contact line is more at present, hangs slide-wire guide rails etc. as tubular type trolley, angle steel formula trolley, rail rigid body trolley, cable, and all there is the investment cost height in above-mentioned trolley, weak points such as overhauling difficulty is installed.
The objective of the invention is at above-mentioned deficiency of the prior art, aim to provide the outdoor high-altitude of a kind of transfer crane trolley safe power supply system.
Summary of the invention
The objective of the invention is to realize in the following manner, the outdoor high-altitude of transfer crane trolley safe power supply system, comprise the naked slip in high-altitude, the slip carriage, current colector, the changed course pulley, movement weight mass, limit switch, after it is characterized in that the naked slips in several high-altitudes (2) pass the vee-cut of the pulley (9) in several current colector pulley assemblings (3) respectively, the slip carriage (10) that is held on the below is gone up in the fixing V-arrangement slip limiting device (12), and an end is connected with an end of insulator (1), the other end of insulator (1) is fixed on the building, the naked slip in high-altitude (2) other end is connected with an end of insulator (4), the other end of insulator (4) is connected with an end of steel rope (6), the other end of steel rope (6) is walked around changed course pulley (5) back and is connected with movement weight mass (7) top, changed course pulley (5) is fixed on the building
The vee-cut of pulley (9) rolls with the naked slip in high-altitude (2) and contacts, current colector pulley assembling (3) is higher than V-arrangement slip limiting device (12), be welded with supporting plate (13) in the V-arrangement slip limiting device (12), limit switch (16) is installed on the building and places movement weight mass (7) below in the same way.
Description of drawings
The present invention is described in detail in detail with reference to the accompanying drawings
Fig. 1 elevational schematic view of the present invention
Fig. 2 schematic top plan view of the present invention
Fig. 3 high-altitude of the present invention slip, current colector, slip carriage end view
Fig. 4 movement weight mass of the present invention, contact-breaker installation site scheme drawing
Fig. 5 V-arrangement slip of the present invention limiting device scheme drawing
The specific embodiment
With reference to figure three, current colector pulley assembling (3) is fixed by insulator (8) and transfer crane (11).
With reference to figure five, insulator (15) two ends are fixed by bolt (14) with V-arrangement slip limiting device (12), slip carriage (10) respectively.
Three-phase mains power cable line is connected with three high-altitude trolleys (2) by AC contactor, AC contactor is by limit switch (16) control circuit break-make, (11) three of transfer cranes are connected with current colector pulley assembling (3) respectively with electrical cables, when high-altitude trolley (2) the vee-cut of electric back by pulley (9) make the current colector pulley assemble (3) must.
Transfer crane (11) is in the mobile operating process, the vee-cut of the pulley (9) in the current colector pulley assembling (3) lifts high-altitude trolley (2), pulley (9) rolls in the below of high-altitude trolley (2) thereupon, falls in the V-arrangement slip limiting device (12) in the effect from gravity after high-altitude trolley (2) leaves pulley (9).When tensile phenomenon in use appears suddenly in certain root high-altitude trolley (2), connected movement weight mass (7) moment this moment can fall downwards, when movement weight mass (7) with place the below limit switch (16) contact after moment namely cut off main power source, guaranteed the safety in utilization of high-altitude trolley.
The present invention is that a kind of slip carriage spacing distance is big, and investment cost is few, the installation maintenance is convenient, safe and reliable is the outdoor high-altitude of the transfer crane trolley safe power supply system that is worthy to be popularized.
Claims (3)
1. the outdoor high-altitude of transfer crane trolley safe power supply system, comprise the naked slip in high-altitude, slip carriage, current colector, changed course pulley, movement weight mass, contact-breaker, after it is characterized in that the naked slips in several high-altitudes (2) several passing the vee-cut of the pulley (9) in the current colector pulley assembling (3) respectively, the slip carriage (10) that is held on the below is gone up in the fixing V-arrangement slip limiting device (12).
2. the outdoor high-altitude of transfer crane according to claim 1 trolley safe power supply service system, the vee-cut of pulley (9) rolls with the naked slip in high-altitude (2) and contacts, current colector pulley assembling (3) is higher than V-arrangement slip limiting device (12), be welded with supporting plate (13) in the V-arrangement slip limiting device (12), limit switch (16) is installed on the building and places movement weight mass (7) below in the same way.
