Description
Technical field
The utility model relates to transmission line and hangs gold utensil, specifically a kind of insulator salt density test string hanging point device.
Background technology
The close value of salt is for stating insulator surface pollution level, determining to play important directive function to the antifouling work of electric power system by the basic parameter of the dirty level of environment.After power transmission and transformation line puts into operation, filthy monitoring point should be set, namely on selected shaft tower, 3 ~ 5 salt density test strings are hung, carry out the sampling of the close value of salt, regularly carry out the close accumulative situation of the close ash of salt to operating insulator to monitor, grasp the contamination degree on electric transmission line isolator surface, this area, improve stability and the reliability of intelligent grid operation.
In prior art; hanging equipment is hung because overhead line structures do not arrange special salt-free density test string; conventional method be use iron wire by the colligation of salt density test string on cross arm of tower; colligation more loose then salt density test string can along cross-arm slippage through wind; colligation tension is then unfavorable for that adjustment is put in the close displacement of salt, and high-altitude construction labour intensity is large.Some salt density insulators strings need long-time suspension (2 ~ 3 years), the impact such as climate, environment, corrosion, iron wire and cross-arm rub and hold very much fracture, cause salt density test string to fall, make number of test points according to collecting, and damage to the pedestrian below shaft tower, vehicle.
In addition, in order to ensure the accuracy of the close value test result of salt, the position of salt density test string hanging point is typically chosen in as far as possible near insulator string position, because iron wire is longer in charged installation process, easily cause the safe distance of iron wire and wire to produce not in operation to discharge, electric shock accidents occurs.
Summary of the invention
The purpose of this utility model is to provide the close string hardware of a kind of test salt, and structure is simple, and salt density test string is installed firmly, easy to use, safe and reliable.
The purpose of this utility model is achieved through the following technical solutions:
A kind of insulator salt density test string hanging point device, comprises the first link plate, the second link plate and the ball-eye for suspending salt density test string; First link plate is slab construction, the second link plate stage casing be provided with horizontal direction opening inside, for the draw-in groove of load-bearing; The two ends up and down of the first link plate and the second link plate connect respectively by connecting bolt; On the mobilizable connecting bolt being connected to first and second link plate lower end of ball-eye.
Further, the described connecting bolt for connecting the first link plate and the second link plate is equipped with retaining pin.
The beneficial effects of the utility model are: hanging point device structure is simple, and volume is little, is convenient for carrying; The suspension of salt density test string is solid and reliable, overcomes the defect of prior art, significantly enhances durability and the fail safe of hanging point device, has stopped the generation of salt density test string falling accident, ensure that the operation of equipment long-term stability; Handling safety is convenient, can quick adjustment hanging point position locking by fastening bolt; Effectively reduce the labour intensity of work high above the ground, improve operating efficiency.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is using state figure of the present utility model.
Embodiment
In figure: 1, the first link plate, the 2, second link plate, 21, draw-in groove, 3, ball-eye, 4, upper connecting bolt, 5, lower connecting bolt, 6, retaining pin, 7, salt density test string, 8, cross-arm angle steel.
Embodiment
As can be seen from Figure 1, technical solutions of the utility model comprise the first link plate 1, second link plate 2 and the ball-eye 3 for suspending salt density test string 7; First link plate 1 is slab construction, the second link plate 2 stage casing be provided with a horizontal direction, for the draw-in groove 21 of load-bearing, make the stage casing draw-in groove part of the second link plate be horizontal, that opening is inside U-shaped; The two ends up and down of the first link plate 1 and the second link plate 2 connect respectively by upper connecting bolt 4, lower connecting bolt 5; The mounting ring set load of ball-eye 3 is connected on lower connecting bolt 5, and can swing around lower connecting bolt 5.
The described connecting bolt for connecting the first link plate 1 and the second link plate 2 is equipped with retaining pin 6, and swing to prevent salt density test string and cause bolt looseness to come off, this retaining pin can select split pin, is convenient to dismounting.
When the utility model uses, the draw-in groove 21 in the middle part of the second link plate 2 is utilized to be installed on the cross-arm angle steel 8 of shaft tower, hanging point device is mounted on shaft tower, fastening upper and lower connecting bolt, and make first, second link plate clamping cross-arm angle steel 8 fix hanging point position by the upper connecting bolt 4 of locking, make it that phenomenon moved left and right along angle steel can not occur, keep ball-eye 3 to swing around lower connecting bolt 5, as shown in Figure 2 simultaneously; Last suspending salt density test string completes and mounts operation.
As need hanging point position be adjusted during circuit runs, only need suitably unscrew connecting bolt 4, make between first, second link plate and cross-arm angle steel 8 lax, hanging point can be moved along cross-arm angle steel.
The utility model hanging point device is simple and reasonable, volume is little, operational motion scope in installation process is little, to increase the safe distance of human body to electrified body, improve the job security of survey crew, by the draw-in groove mounting cross-arm angle steel in the middle part of the second link plate in installation process, without the need to lifting support, be convenient to regulate hanging point position simultaneously; Hanging point device and cross arm of tower adopt face to contact, make the suspension of salt density test string solid and reliable, enhance durability and the fail safe of hanging point, overcome the defects such as the colligation of prior art iron wire is wasted time and energy, the close string of salt easily falls, reduce the labour intensity of work high above the ground, improve operating efficiency.
Finally should be noted that: above embodiment is not intended to limit for illustration of the technical solution of the utility model; those skilled in the art modifies to execution mode or carries out equivalent replacement to portion of techniques feature; and do not depart from the essence of technical solutions of the utility model, all should be encompassed within the utility model scope required for protection.
