Description
Technical field
Auxiliary device when the utility model relates to a kind of electric system maintenance activity, especially a kind of guide chain of lifting distribution transformer of simple and convenient.
Background technology
At present, the mountain area power supply station especially in rural area, voltage transformer and JP cabinet are installed and are changed more frequently, and crane can be used in place with good conditionsi, and operating cost is higher.But in remote mountain areas, its voltage transformer may be arranged on hillside, do not possess in the situation of using crane condition, can only lean on manpower that voltage transformer and JP cabinet are installed and changed.Current operational method is first the lightning arrester of the top of distribution transformer installation site to be removed, an another attached cross-arm on lightning arrester cross-arm, this cross-arm is more much larger than the intensity of the angle steel of installation lightning arrester, then with iron wire by the hoist colligation of guide chain in the middle of cross-arm, then by guide chain sling voltage transformer or JP, just can install and change.The existing problem of measure of taking at present has: 1, inefficiency (needing to dismantle lightning arrester before work, another attached large cross-arm on lightning arrester cross-arm).2, there is potential safety hazard (during additional cross-arm, easily coming off).3, there is economic attrition (additional cross-arm is easily bent).4, malfunction (because guide chain is fixed, institute's voltage transformer that hangs or JP cabinet can only straight up and down cannot swing, and dodge holder load).
Utility model content
The technical problems to be solved in the utility model is to provide a kind of allocated radio lifting guide chain, it have carry, easy to operate, economical and practical feature, and can make to be hung device avoiding obstacles.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
With the matching used allocated radio lifting of two electric poles guide chain, the steel rope that comprises the rope sling that two ends are shaped with, the hoist of cross-under guide chain on steel rope, described rope sling is after the bending of the end of steel rope and the rope body of steel rope forms by wire clips is fastening, is also connected with hook on rope sling; Described wire clips comprises a U-bolt and two nuts, and on the double-screw bolt of U-bolt, cross-under has deck.
The utility model further improves and is: described wirerope diameter is 8 millimeters～12 millimeters, and length is 4.5 meters.
Owing to adopting technique scheme, the obtained technological advance of the utility model is:
Above distribution transformer installation site, be generally all provided with lightning arrester cross-arm is installed, the cross-arm that lightning arrester is installed is generally the angle steel of a small dimension model.The utility model in use, steel rope two ends can be walked around after electric pole and cross-arm, with hook, catch on steel rope, steel rope and guide chain are just fixedly connected on the top of voltage transformer like this, just can lift by crane the equipment such as voltage transformer or JP cabinet, need not dismantle the lightning arrester on the cross-arm of voltage transformer top.The utlity model has easy to carry, easy to operate feature, economical and practical.The length of steel rope of the present utility model can not be too short, be generally 4.5m, select this length can be in hoisting process, make steel rope certain distance that swings, the obstacles such as stand that therefore can make to be hung device and avoid installation voltage transformer below, can not have influence on the lifting of voltage transformer.
If while meeting the close together of two electric poles that voltage transformer is installed, can be by steel rope of the present utility model directly as stated above around being enclosed within on electric pole, due to the Action of Gravity Field of chain sling and hanging object, between rope sling and electric pole, also can, because there being friction force to hold tightly, also can reach the height of lifting.If while meeting two electric poles distant that voltage transformer is installed, can, by hanging over the outer end of the cross-arm that lightning arrester is installed between rope sling of the present utility model, also can normally use.
In addition, rope sling of the present utility model is compressed and is formed by wire clips, while meeting particular distance, can unclamp the nut on wire clips and adjusts the length of steel rope, to adapt to the size of different electric pole distance, hoisting height and obstacle.10 millimeters of wirerope diameters of the present utility model, can meet load-carrying capacity and be unlikely to again to seem because diameter is excessive heavy, have also saved material simultaneously, are easy to carry; Steel rope and rope sling are made into an integral body by wire clips, both durable, are convenient to again make, and expense is cheap, have solved current remote mountain areas voltage transformer and JP cabinet and have installed and a difficult problem of changing.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation that uses state of the utility model;
Fig. 2 is the integral structure schematic diagram of steel rope of the present utility model;
Fig. 3 is the structural representation of rope sling;
Fig. 4 is the structural representation of wire clips.
In the accompanying drawings: 1, steel rope; 2, rope sling; 3, wire clips, 3.1, U-bolt, 3.2 decks, 3.3, nut, 4, hook, 5, guide chain, 6, electric pole, 7, cross-arm.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
The utility model is that the hoist of chain sling 5 is connected on a steel rope 1, and wire clips 3 rope sling 2 of tiing a knot out for steel rope two ends also connects a hook 4 on rope sling 2, like this steel rope 1, rope sling 2, a lifting rope of hook 4 formation.The diameter of steel rope 1 is preferably elected 8 millimeters～12 millimeters as, and length is preferably 4.5 meters.Rope sling 2 can directly overlap hang over lightning arrester cross-arm two ends, electric pole outside, also can be by steel rope two ends on electric pole or the junction of electric pole and lightning arrester cross-arm, with hook, catch on steel rope, steel rope and guide chain are just fixedly connected on the top of voltage transformer like this, just can lift by crane the equipment such as voltage transformer or JP cabinet, need not dismantle the lightning arrester on the cross-arm of voltage transformer top.
Rope sling 2 of the present utility model is that the end bending of steel rope 1 rope body rear and steel rope 1 is drawn close, and then with wire clips 3 is fastening, forms.Described wire clips 3 comprises a U-bolt 3.1, on two double-screw bolts of U-bolt 3.1, a deck 3.2 in cross-under is then screwed into a nut 3.3, after steel rope is put between U-bolt and deck on each double-screw bolt, screw nut 3.3 and just two steel ropes can be compressed, form rope sling.
During use, steel rope two ends are connected on electric pole 6 or the two ends of lightning arrester cross-arm 7 by hook or rope sling, fix after hoisting rope, guide chain is hung on hoisting rope, distribution transformer is positioned at the below of guide chain, by guide chain, distribution transformer is risen on voltage transformer cross-arm and can complete lifting task.
