Fig. 2 is the top view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the rear elevation of Fig. 1.
In figure: the little cross-arm of 1-, 2-fastening bolt auxiliary connection, 3-embraces iron, 4-link, 5-suspender belt.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1,2,3 and shown in Figure 4, a kind of cross-arm dismounting assistor, it is characterized in that: comprise two little cross-arms 1, two fastening bolt auxiliary connections 2, the two ends of described every little cross-arm 1 are provided with a corresponding aperture, described two fastening bolt auxiliary connections, 2 covers are through in the hole at little cross-arm 1 two ends, two little cross-arms 1 are fastening, can be by adjustment hole apart from the size that adapt to pole diameter when bolt passes the hole at little cross-arm 1 two ends.
Preferably, the middle part of described little cross-arm 1 is fixedly installed embraces iron 3, embraces iron 3 and can use the replacements such as angle bar, iron block, arc iron.
Preferably, also comprise four suspender belts 5, described four suspender belts 5 hang respectively the two ends that are located at two little cross-arms 1.
Preferably, described suspender belt 5 one ends are fixed on the end of little cross-arm 1, and the other end is provided with hook, and the end of little cross-arm 1 is provided with link 4 or hanging hole.
Preferably, but described hook is opening locked hook, and in the time of can preventing that cross-arm weight is larger, deformation of hook, cross-arm come off.
Preferably, described suspender belt 5 is provided with length-adjustment buckle, can regulate according to the installation site of cross-arm the height of cross-arm while utilizing suspender belt 5 lifting cross-arm.
Preferably, described little cross-arm 1 is the ∟ 40*40 galvanized angle iron of long 50cm, and the contact area of cross-arm and cross-arm dismounting assistor is increased, and the wide angle bar of 40mm can meet the installing space of M16 bolt and nut, the long 80cm of described suspender belt 5, can meet the installation requirement of all kinds of cross-arms.
" holder " with " hangs " the installation or removal operation of two kinds of forms to utilize " cross-arm dismounting assistor " to complete.While utilizing the lifting form of cross-arm dismounting assistor to carry out the installation or removal operation, operating personnel step on after bar and cross-arm dismounting assistor are provided with to the one side of embracing iron 3 and are close to electric pole and fix, be arranged on the 20cm place, cross-arm top that needs installation or removal, utilize fastening bolt auxiliary connection 2 by two little cross-arm 1 fixations, then four suspender belts 5 are hooked in the cross-arm of the required installation hook that rear use can lock that winds with one circuit in the two ends link 4 or hanging hole of cross-arm dismounting assistor, form closed circuit lifting.Because suspender belt 5 is length adjustable, generally by under cross-arm dismounting assistor, being 20cm along the central horizontal face to required installation cross-arm, may also be adjusted to as required 15cm or 10CM etc., by the length-adjustment buckle on suspender belt 5, regulate the installation site of cross-arm, it is in order to make suspender belt 5 produce the self-tightening effect that four suspender belts 5 wind with one circuit, make the cross-arm lifting more firm, can avoid rocking because of the electric pole shaft, the staff touches carelessly, or high wind blows the dangerous phenomenons such as cross-arm that the unsafe factor such as cross-arm causes swings, glides or comes off and occurs.After lifting, the bolt hole of cross-arm is namely automatically corresponding, the adjustment cross-arm direction that installation personnel can be easy and convenient and wear fastening bolt, the fastening bolt that installation personnel only needs to put on is tightened, and cross-arm is fixed, just can like a cork cross-arm be installed on need to position.When the dismounting of carrying out cross-arm or replacing operation, operation sequence is the same with installation.
Another embodiment is the support form, cross-arm dismounting assistor is provided with to the one side of embracing iron 3 to be close to electric pole and to fix, cross-arm dismounting assistor is set directly to the below, position that needs to install cross-arm, utilize fastening bolt auxiliary connection 2 by two little cross-arm 1 fixations, then cross-arm is on the little cross-arm 1 of cross-arm dismounting assistor, utilize cross-arm dismounting assistor to do positioning supports, suspender belt 5 changes by upwards being wound around, by " day " the font length-adjustment buckle of regulating suspender belt 5 length, block cross-arm, keep cross-arm to be adjacent to electric pole, then suspender belt is after cross-arm was wound around for two weeks, with the hook that can lock, be hooked in the two ends link 4 or hanging hole of cross-arm dismounting assistor.In like manner, in the dismounting of carrying out cross-arm or while changing operation, operation sequence is the same with installation, thus installation or removal cross-arm rapidly and accurately.
This apparatus structure is simple, easy to operate, accurate positioning, comprehensive strong, easy to carry, high efficiency, has also reduced the input of personnel and fund simultaneously, itself can regulate the installation diameter dimension to adapt to each model electric power electric pole.After using " cross-arm dismounting assistor ", can or more change jobs to change by a people by cross-arm installation, the dismounting of needs two people's cooperations and complete, reducing the recruitment number of installing, when reducing labour intensity, improve operating efficiency and the safety of cross-arm installation or removal work, can be widely used in the cross-arm installation or removal work in power construction.In actual job, the installation or removal work of single cross-arm is used this assistor also can play to reduce labour intensity and is increased work efficiency and the effect of safety.
