A Sliding Line Structure with Improved IP Protection Level

Abstract

The invention discloses a trolley conductor structure for increasing IP protection grade. The structure comprises a wire jacket provided with an opening on the top face and a current collector movably connected to the wire jacket; the current collector comprises an electronic brush box arranged in the wire jacket in a sleeved mode and a flat rectangular junction box; the bottom of the junction box is connected to the top of the electronic brush box, and the top of the junction box extends out of the opening; the left side and the right side of the top face of the wire jacket are provided with an A type bending piece and a B type bending piece respectively, wherein the A type bending piece and the B type bending piece are in an angle steel shape; transverse folding parts of the two bending pieces are relatively opposite; the vertical folding part of the A type bending piece is connected to the right brim opening of the opening on the top of the wire jacket, and the vertical folding part of the B type bending piece is connected to the left vertex of the top face of the wire jacket body; the width of the vertical folding part of the B type bending piece is bigger than that of the vertical folding part of the A bending piece, and the width of the transverse folding part of the B type bending piece is bigger than that of the transverse folding part of the A bending piece; the transversely arranged junction box is connected to the top face of the electronic brush box through a left toward transversely arranged n-shaped three-fold bending piece and then through a stripe-block box. The IP protection grade is higher.

Description

technical field [0001] The invention belongs to the technical field of construction elevators, and relates to a construction elevator trolley line, in particular to a trolley line structure with improved IP protection level. Background technique [0002] The trolley line of the construction elevator is the power supply current channel of the elevator, and its IP protection level is very important for the safe operation of the elevator. [0003] The structure of the trolley line in the prior art is as follows: figure 1 , figure 2 As shown, the top surface of the cover body is provided with a square tubular line cover 4 with a long straight opening top opening 1, and a current collector that is movably connected with the line cover 4; The slot is inserted with a corresponding conductive strip 3; the collector includes a square box-shaped brush box 5 and a flat rectangular box-shaped junction box 2 that are sleeved in the wire sleeve 4; the bottom of the junction box 2 is co...

Problems solved by technology

[0004] The sliding contact wire structure adopting such technology can certainly be used, but its long straight open-shaped top opening 1 is a weak point in safety. The rod-shaped body outside the wire sleeve 4 is obviously easy to stretch into the inner cavity of the wire sleeve 4, and the IP The protection level is low, the electrical safety reliability is not high enough, and the use effect is not ideal enough
