Abstract

The utility model discloses a push-open device for a gap of an iron tower, which comprises a bidirectional force application device in a major structure of a general tightener, wherein the bidirectional force application device comprises two screw rods that are opposite in spiral direction; the screw rods are connected with the two ends of a sleeve through sleeves with left-hand threaded nuts and right-hand threaded nuts to form a bidirectional lead screw structure; a ratchet wrench is arranged in the middle of the sleeve; through the operation of the ratchet wrench, the sleeve can rotate to allow the two screw rods to move oppositely; cross arms vertical to the axes of the screw rods are arranged at the ends of the screw rods, which are exposed outside the sleeve; the two cross arms are parallel to each other and symmetrical along the axis of the ratchet wrench; a strengthened lining pin used for preventing each cross arm from deforming is welded between each of the two ends of each cross arm and each corresponding screw rod; and the push-open device is light in weight, convenient in operation and fast in mounting; and formerly, the push-open device is unavailable, and a controllable lightning conductor base cannot be mounted into the gap of the iron tower originally, while the push-open device shortens the time of mounting the base into the gap of the iron tower to be less than 3 minutes, thereby greatly shortening the operation time.

Description

Iron tower space distraction device
Technical field
The utility model relates to electric power accessory appliances field, particularly a kind of iron tower space distraction device.
Background technology
For power supply enterprise, pass through the transmission line of electricity in mountain area, the probability that its line insulator is struck by lightning is very high, and thunderbolt causes the possibility of power failure also very big; At present, it is the effective ways that prevent line tripping that transmission line of electricity is installed additional controlled discharging rod, but if guarantee in work progress, not have a power failure, unique method is exactly the controlled discharging rod of charged installation.
The pedestal of the charged controlled discharging rod of goat's horn strain insulator iron tower is formed by two sections, and wherein, lower end length is 1 meter; Need theoretically, need only discharging rod pedestal length and be not more than 1 meter through being bolted to goat's horn tower center line hanging wire cross-arm to the gap of goat's horn bifurcation; Gap in the middle of the iron tower is not less than 1 meter, and material and the tower material between the iron tower gap of making pedestal are smooth, and the operating personnel is in strict accordance with standardized work; Base level is advanced in the gap of goat's horn tower, just can accomplish installation smoothly.But, the operating personnel in installation process very major part all can't install into.Its reason is:
1. the gap of iron tower is less than 1 meter, and according to the iron tower design standard, this gap design is of a size of 1 meter, in fact, and on the one hand because iron tower is made, work progress is nonstandard; On the other hand, have certain clearance between iron tower junction bolt and the bolt eyelet, under the situation of iron tower self gravitation and the extruding downwards of lead gravity, cause actual gap less than 1 meter, in actual measurement, the gap is essentially 998----999mm.
2. controlled discharging rod pedestal is made nonstandard, and overlap or burr etc. are arranged, and size is between 999-----between the 1001mm.
Therefore, be necessary to design a kind of auxiliary instrument of installing of controlled discharging rod pedestal that is used for.
Summary of the invention
In view of this, one of purpose of the utility model provides a kind of iron tower space distraction device, has advantage in light weight, easy to operate, time saving.
The purpose of the utility model realizes through following technical scheme:
This iron tower space distraction device, said iron tower space distraction device comprises the bidirectional force applying device that adopts general turnbuckle agent structure, said bidirectional force applying device comprises two screw rods that hand of spiral is opposite; Said screw rod is connected the two ends of sleeve respectively with the sleeve that has left and right sides spin nut; Form two-way screw structure, the middle part of said sleeve is provided with free wrench, through the operation of free wrench; Sleeve is rotated, make two screw rods take place to move in opposite directions;
Said screw rod is exposed to the exterior end of sleeve and is provided with the cross-arm vertical with screw axis; Two cross-arms are parallel to each other and along the axis symmetry of free wrench, are welded with respectively between the two ends of said cross-arm and the cooresponding screw rod to be used to the reinforcing line pin that prevents that cross-arm is out of shape.
Further, be wound with anti-skidding rubber on the said cross-arm;
Further, also be welded with limiting stopper on the two ends of said cross-arm respectively.
The beneficial effect of the utility model is:
1. this installation weight is light, and is easy to operate, installs rapidly, and contrast before this device, from can't controlled discharging rod pedestal being installed into originally, does not shorten to less than the pedestal in 3 minutes completion iron tower gaps and installs, and has shortened production time in a large number;
2. this device has been saved a large amount of muscle power of operating personnel, has ensured safety of operation, is fit to promote the use of.
Other advantages, target and the characteristic of the utility model will be set forth in specification sheets subsequently to a certain extent; And to a certain extent; Based on being conspicuous to those skilled in the art, perhaps can from the practice of the utility model, obtain instruction to investigating of hereinafter.The target of the utility model and other advantages can realize and obtain through following specification sheets and claims.
Description of drawings
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model is done further to describe in detail below, wherein:
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Below will be with reference to accompanying drawing, the preferred embodiment of the utility model is carried out detailed description.Should be appreciated that preferred embodiment has been merely explanation the utility model, rather than in order to limit the protection domain of the utility model.
As shown in Figure 1, the iron tower space distraction device of the utility model comprises the bidirectional force applying device 1 that adopts general turnbuckle agent structure; Said bidirectional force applying device 1 comprises two screw rods 2 that hand of spiral is opposite, and screw rod 2 is connected the two ends of sleeve respectively with the sleeve 3 that has left and right sides spin nut, form two-way screw structure; The middle part of sleeve 3 is provided with free wrench 4; Through the operation of free wrench 4, sleeve 3 is rotated, make two screw rods 2 take place to move in opposite directions;
In addition; Be exposed to the exterior end of sleeve at screw rod and be provided with the cross-arm vertical 5 with screw axis; Two cross-arms 5 are parallel to each other and along the axis symmetry of free wrench 4, are welded with respectively between the two ends of cross-arm 5 and the cooresponding screw rod 2 to be used to the reinforcing line pin 6 that prevents that cross-arm is out of shape.
As further improvement, on cross-arm, be wound with anti-skidding rubber, thereby can guarantee non-sliply when in use, avoid influence to strut effect.
As further improvement, on the two ends of cross-arm, also be welded with limiting stopper 7 respectively, see from the side that promptly this cross-arm is "] of an outer opening " the shape structure, thus guarantee fixed effect.
During use, the cross-arm at device for spreading two ends is propped up the both sides tower material that forms the iron tower gap respectively,, make screw rod relative to outwards moving, thereby strut the iron tower gap, thereby satisfy the installing space of lightning arrester pedestal through cross-arm then through the operation free wrench.
The iron tower space distraction device of the utility model is made through following steps:
