The utility model provides a present hoist tow-cable coaster pull wire rope fluff thorn or damage the problem of tow-cable after disconnected thigh.
Description
Technical Field
The utility model relates to a hoisting equipment technical field, in particular to a draw gear for overhead traveling crane towline.
Background
Power cable and control cable on the monkey, walk along with the dolly on the cart roof beam through utilizing tow-cable coaster and traction wire rope, at the walking in-process, wire rope strand breakage easily, the burr and scratch tow-cable, the steel wire of burr or the steel wire of strand breakage insert in the tow-cable easily, cause cable ground connection to form the short circuit, equipment trouble takes place, secondly in order to ensure equipment operation safety, as long as wire rope burr or the strand breakage appears, just must change, need lift off the wire rope checkpost during the change, wire rope takes out, penetrate intact wire rope again, beat the checkpost, and this process needs 8 hours at least, direct influence production. Because of relying on the high altitude construction, the potential safety hazard is easy to occur when the high altitude construction is carried out for a long time, and simultaneously, the whole steel wire rope which is broken or has burrs is dismounted by manpower during replacement, thereby wasting time and labor and having high labor cost and also increasing the labor intensity of personnel. In addition, under the long-term high load operation of the crane, sometimes the trolley traction steel wire rope is broken, so that the towing cable is directly stressed to follow the trolley, the towing cable can be directly broken for a long time, and then the towing cable of the trolley is broken, the production operation of the crane is directly influenced, and unnecessary economic loss is caused.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a draw gear for overhead traveling crane towline can avoid present hoist towline coaster to pull wire rope fluff thorn or the problem of disconnected strand after damage towline.
In order to achieve the above object, the technical solution of the present invention is specifically as follows:
the utility model provides a draw gear for overhead traveling crane tow-cable, includes horizontal guide, coaster, sliding connection a plurality of coaster on the horizontal guide, be provided with detachable installation component on the coaster, adjacent two through detachable iron chain interconnect between the detachable installation component, the tow-cable passes through detachable installation component is fixed on the coaster.
The detachable installation component comprises an arc-shaped plate, the arc-shaped plate is detachably and fixedly installed on the pulley, and the towing cables are placed on the arc-shaped plate.
The arc-shaped plate is fixedly installed on the pulley through a fixing bolt.
The two ends of the iron chain are provided with quick connecting rings, and the quick connecting rings are connected with the arc-shaped plate through connecting holes formed in the arc-shaped plate.
The utility model has the advantages that: the utility model discloses a detachable installation component and detachable iron chain realize the connection between two adjacent coasters to and arranging and fixing of towing cable, simple high-efficient, abandoned current wire rope's connected form, effectively avoided the disconnected strand of wire rope, the fluff thorn and the problem of scratch towing cable. Wherein, detachable installation component includes the arc, and arc detachable fixed mounting is on the coaster, and the arc is used for placing the towline and realizes being connected between the adjacent coaster, provides the protection for the towline, also provides support and installation face for the towline. Wherein, in order to reduce use cost, improve the work efficiency of installation maintenance, the arc passes through fixing bolt fixed mounting on the coaster. In order to realize the quick installation of iron chain to and the dismantlement of iron chain change efficiency, the iron chain both ends all are provided with quick go-between, and quick go-between is connected with the arc through setting up the connecting hole on the arc.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, a draw gear for overhead traveling crane tow-cable, including horizontal guide 1, coaster 2, sliding connection a plurality of coaster 2 on horizontal guide 1, be provided with detachable installation component on coaster 2, through detachable 5 interconnect on the iron chain between two adjacent detachable installation components, tow-cable 6 passes through detachable installation component to be fixed on coaster 2, detachable installation component includes arc 3, 3 detachable fixed mounting of arc are on coaster 2, place tow-cable 6 on arc 3, arc 3 passes through fixing bolt 7 fixed mounting on coaster 2, 5 both ends of iron chain all are provided with quick go-between 4, quick go-between 4 is connected with arc 3 through setting up the connecting hole on arc 3.
When the utility model is used, a vertical bracket with the same height is welded on a girder of the crane and is used for fixing a horizontal guide rail 1, a movable pulley 2 is arranged on the horizontal guide rail, a bottom plate of the pulley 2 is fixed with an arc-shaped plate 3 through a bolt 7, a towing cable 6 is fixed between the bottom plate of the pulley 2 and the arc-shaped plate 3, two ends of the arc-shaped plate 3 are respectively provided with a connecting hole, for connecting a quick connecting ring 4, the arc-shaped plate 3 is connected with an iron chain 5 through the quick connecting ring 4 and is fixed on each moving trolley 2 in such a way that the span of the iron chain 5 between every two moving trolleys 2 is smaller than that of a towing cable 6, when the trolley walks to draw the first pulley 2 to move, the pulley can drive the iron chain 5 to move, because the span of the iron chain 5 is less than that of the towing cable 6, the iron chain 5 is firstly tightened and simultaneously drives the second pulley 2 to move, and so on, the towing cable 6 is realized to walk along with the trolley.
The dolly is at the walking in-process, and only the friction that sways between iron chain 5 and the tow-cable 6 has directly eliminated the phenomenon of wire rope strand breakage or wire rope fluff thorn, will not take place again simultaneously because the wire rope strand breakage or the tow-cable short circuit trouble that the wire rope fluff thorn caused, directly eliminated equipment potential safety hazard, still eliminated the phenomenon of wire rope torsional strength simultaneously.
If the iron chain 5 breaks off in the walking process, the maintainer or the crown block operator only needs to connect the arc plate 3 and the iron chain 5 together by using the quick connecting ring 4, so that the operation is simple, convenient and quick, the operation and maintenance cost is reduced, and the working efficiency is also improved.
When changing the tow-cable 6, only need to twist off the fixing bolt 7 that each coaster 2 and arc 3 are connected one by one, pull down old and useless tow-cable 6, new tow-cable is put away, twists off the fixing bolt 7 that each coaster 2 and arc 3 are connected one by one again, it is convenient, quick to change.
If the iron chain 5 breaks off in the walking process, the maintainer or the crown block operator only needs to connect the arc plate 3 and the iron chain 5 together by using the quick connecting ring 4, so that the operation is simple, convenient and quick, the operation and maintenance cost is reduced, and the working efficiency is also improved.
The above are merely examples of the present invention, and the scope of the present invention is not limited thereby. In addition to the above embodiments, the present invention can also have other embodiments, and all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
