Description

The trailed equipment of electric block supply cable

The utility model relates to a kind of trailed equipment that is used for the electric block supply cable, particularly a kind ofly is applicable to pulling of the electric block supply cable that moves on irregular monorail.

Little, that space structure is special at fitfull, area, often need in work workshop, factory building or the storehouse of handling than heavy object again, generally be not suitable for installing " bridge-type " or " masts type " hoisting crane, can only install start flexible, easy and simple to handle, bear and hang the bigger again electric block of load.In addition because space structure special, causing the running orbit of electric block irregular, is open change locus of radius, therefore can not set up slide wire power supply, can only adopt soft Plastic-sheathed Cable power supply, so just a problem of how to set up soft Plastic-sheathed Cable occur to the electric block power supply.

Be used at present at the erection mode of the supply cable of the electric block that moves on the irregular monorail be: on soft Plastic-sheathed Cable, whenever be spaced a distance and fix an annulus, and all annulus are enclosed within on the Metallic rod, one end of Metallic rod is connected on the electric block by metallic bond, the other end is overlapped on by wire rope hanging on the pulley groove on the structure-steel framing, when electric block during along the operation of irregular single track, drive Metallic rod and on pulley groove, freely slidably reciprocate, reached and pulled the purpose of cable to the electric block power supply.But because Metallic rod utilizes metallic bond to be connected with electric block, in operational process because of metallic bond repeatedly turn round hinge, cause fracture easily, simultaneously can be owing to jolt and swing along with Metallic rod flexible produces by the pulley of wire rope hanging on structure-steel framing, cause the dangerous of electric block handling work, this kind structure generally just needed steel rope and metallic bond are changed once in two months, brought great waste to human and material resources.

The purpose of this utility model is to provide a kind of trailed equipment that is used for the electric block supply cable, make Metallic rod and electric block be connected and the overlap joint of pulley groove can not occur the phenomenon of the fracture and the swing of jolting because of the motion of electric block, thereby reached the purpose of safe power supply.

The purpose of this utility model is to realize like this, steel ball of end welding of several cable pulling tracks that are fixed on the annulus on the cable will be installed with, steel ball is put into the diameter of Spherical Volume of the traction seat device of installing on the electric block, the other end of cable pulling track is overlapped on the holder rail furrow wheel of universal track riding wheel apparatus, along with moving of electric block, steel ball rotates in diameter of Spherical Volume, and the cable pulling track freely slidably reciprocates on holder rail furrow wheel.

The trailed equipment of electric block supply cable of the present utility model, its traction seat device is to become the steel part of spherical concave surface with two internal operations by being vertically welded in seat board on the electric block one side elevation boatswain chair, passing bolt hole on seat board and two steel parts with bolt is connected and forms, make the concave surface of two steel parts relative, so that form a diameter of Spherical Volume.

The trailed equipment of electric block supply cable of the present utility model, its universal track riding wheel apparatus is to be connected by axle and two clamping plate by fixed arm, regulating arm and holder rail furrow wheel to form, one end of fixed arm is welded on the structure-steel framing, the other end is connected up and down with an end of regulating arm by axle, on axle, be with pressure bearing and fixing, so that regulating arm is around this along continuous straight runs rotation with the nut adjusting; On the hole of the other end of regulating arm, vertically penetrate one, the upper end of axle is with bearing, and regulate with nut and to be fixed on the regulating arm, so that this axle can freely rotate on regulating arm, in the lower end of axle one axis hole is arranged, at the axis hole two ends clamping plate with holes about in the of are arranged respectively, the upper end hole that passes clamping plate by axostylus axostyle is connected with this, a holder rail furrow wheel that is with bearing is arranged between the following stomidium of two clamping plate, to ask the rail furrow wheel to be connected between two clamping plate by axostylus axostyle, so that holder rail furrow wheel rotates on axostylus axostyle.

The utlity model has advantages such as simple in structure, reasonable in design, flexible and convenient to use, solved in the past when using the trailed equipment of electric block supply cable, the easily fracture of cable pulling track that occurs and electric block junction and swinging up and down of track riding wheel apparatus and problems such as jolting of causing, make the very steady and harmony in operational process of whole device, can reach more than 10 years service life, thereby reached the purpose of saving human and material resources and safe power supply.

The utility model is described in further detail below in conjunction with accompanying drawing.
