Abstract
The utility model discloses a trolley flexible cable protective device, in order to solve the problems that in the prior art, a drag chain structure is high in sliding friction; a drag chain is easy to damage, and is high in installation and maintenance cost and the like. The trolley flexible cable protective device comprises a drag chain and a trolley, wherein the drag chain is arranged on a main beam upper cover plate of an electric conducting side; the trolley slides on trolley railways. The technical scheme is as follows: a connecting plate is arranged between the end beam of the trolley and the main beam of the electric conducting side; one end of the drag chain is fixed on the connecting plate through a drag chain moving end joint, and the other end of the drag chain is fixed on the main beam of the electric conducting side through a drag chain fixed end joint; the main beam of the electric conducting side is also provided with a roller for supporting the drag chain so as to prevent the mutual friction between the middle part of the drag chain and the main beam upper cover plate of the electric conducting side when the drag chain is at the bent state; the service life of the drag chain is prolonged. The trolley flexible cable protective device belongs to the field of crane equipment, and is mainly suitable for bridge-type cranes.
Description
Technical field
The utility model belongs to the weight-lifting equipment field, is a kind of dolly flexible-cable fender guard specifically, mainly is applicable to crane in bridge type.
Background technology
Crane in bridge type be crossbearer in the workshop, warehouse and overhead, the stock ground weight-lifting equipment that carries out the material handling.Because its two ends are seated on tall and big concrete column or metallic support, shape is like bridge.The crane span structure of crane in bridge type vertically moves along being laid on the track of both sides on overhead, can take full advantage of the space handling material below crane span structure, is not subjected to the obstruction of wayside equipment.It is a kind of elevator machinery that range of use is the widest, quantity is maximum.
The dolly feeder equipment uses cable, copper slip, angle steel or other conductive material usually.The diameter of copper slip is not less than 6mm, and the angle steel size is not less than 40x40x4mm.Compare with copper slip, angle steel power supply, the dolly cable power supply can be avoided the exposed Danger Electric shock risk that occurs outside; Cable coaster is a kind of desirable electric power system, can be divided into two kinds of C type rail cable coaster and H type cable coasters according to the difference of track, and this system is lower to the requirement of environment, operates steadily and does not produce spark, all can work at indoor, outdoor dirty environment.Be widely used in various general-purpose overhead cranes, transfer crane etc.But coaster is long-term pull the cable wearing and tearing large, and be deposited in when needing supporting I-beam section and higher flange beam stand to avoid cable sagging walk on stage on, when a coaster damaged, a whole set of coaster all needed to dismantle, maintenance capacity is large.
Drag chain is a kind of novel safety moving cable protecting device; drag chain is similar to tank chain outward; formed by numerous cellular chains; rotate between link freely, the interior height of the drag chain of same train, outer height, pitch are identical, and drag chain inner width, bending spring can carry out as required comformability and select; the unit chain link is comprised of left and right carrier bar and upper and lower cover plates; the every joint of drag chain can be opened, and mounting or dismounting are convenient, can put into drag chain to cable after opening cover plate.Separately can provide shim, space in chain is separated on demand.Be used widely in industries such as numerically-controlled machine tool, stone machining equipment, glass machinery, door and window machinery, manipulator, Automatic Warehouses.Rarely have producer to use drag chain in the crane in bridge type industry, discovery drag chain in service can directly drop down onto nadir from vertex, repeat such motion impact very large to drag chain and nadir larger to the drag chain friction, greatly reduced the drag chain life-span, drag chain, the cable of conventional confguration very easily damage.For this reason, need badly existing drag chain structure is improved.
Summary of the invention
The purpose of this utility model is to provide a kind of dolly flexible-cable fender guard, has solved in prior art the drag chain structure cliding friction large, and drag chain is fragile, installation and maintenance high in cost of production problem.To avoid drag chain under case of bending, make drag chain middle part and the mutual friction of conductive side girder upper cover plate phase, the service life of having improved drag chain.
The purpose of this utility model is achieved in that it comprises the drag chain that is arranged on conductive side girder upper cover plate, the dolly that slides on trolley track, its technical essential is: be provided with connecting panel between described dolly end carriage and conductive side girder, drag chain one end is fixed on connecting panel by drag chain mobile terminal joint, and the drag chain other end is fixed on the conductive side girder by drag chain fixed end joint; Also be provided with on the conductive side girder for the running roller that supports drag chain.
Described drag chain mobile terminal joint or drag chain fixed end joint are made by abrasion-proof stainless steel.
Advantage of the present utility model and beneficial effect are as follows: in drag chain lowest part bottom, roller structure is set, has reduced the vertical distance between drag chain highest point and lowest part, the impact when greatly reducing drag chain and falling; Make cliding friction change friction of rolling into, the power of reducing friction; First section of drag chain is fixed on the girder middle part, and tail end is fixed on dolly, when drag chain moves back and forth with dolly, can be crooked with safe minor radius, and avoid the mechanical damage of cable, extended the service life of drag chain, reduced the production maintenance cost; Cable is arranged together regularly, improved the aesthetic property of equipment; Easy for installationly take up room littlely, save cable length 55%, reduced cost of installation; The every joint of drag chain can be opened, and can dock voluntarily according to actual length, is easy for installation and maintenance; But low, the wear-resisting high-speed motion of noise during motion; The utility model also has simple in structure, and is applied widely, the advantage such as is easy to promote the use of.

Below in conjunction with accompanying drawing and by example, utility model is described in further detail; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
The specific embodiment
According to Fig. 1 ~ Fig. 4, the utility model is described in detail.This dolly flexible-cable fender guard comprises the drag chain 5 that is arranged on conductive side girder upper cover plate 3, the assemblies such as dolly that slide on trolley track 6.Wherein be provided with connecting panel 10 between dolly end carriage 4 and conductive side girder 9, an end of drag chain 5 is fixed on connecting panel 10 by drag chain mobile terminal joint 7, and the other end of drag chain 5 is fixed on conductive side girder 9 by drag chain fixed end joint 8.Also be provided with on conductive side girder 9 for the running roller 11 that supports drag chain 5, to avoid drag chain under case of bending, make drag chain middle part (being drag chain nadir 2 before improving) and the 3 phase mutual friction of conductive side girder upper cover plate.Adopt before of the present utility model being designed with, drag chain 5 is in the crank motion of crooked, level, and the suffered downward pulling force of drag chain vertex 1 is very big, and drag chain is damaged, and has reduced drag chain service life.In crank motion, drag chain nadir 2 constantly rubs with conductive side girder upper cover plate 3, has reduced drag chain service life.Adopt when drag chain moves back and forth with dolly after design of the present utility model, can be crooked with safe minor radius, avoid the mechanical damage of cable, extended the service life of drag chain, reduced the production maintenance cost.During use, cable is arranged in drag chain box regularly, has improved the aesthetic property of equipment, save cable length, reduced cost of installation.
