There is the required accompanying drawing used in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments described in application, for those of ordinary skill in the art, on the premise of not paying creative work,
Other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is block corner block front view when high voltage power transmission provided by the invention is constructed；
Fig. 2 is along A1-A2 sectional view in Fig. 1；
Fig. 3 is corresponding side view when upper hanging plate provided by the invention is opened.
Embodiment
In order that those skilled in the art more fully understand the present invention program, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only this
Invention part of the embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art exist
The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Referring to Fig. 1, block corner block front view when the figure is high voltage power transmission construction provided by the invention.Referring to Fig. 2,
The figure is along A1-A2 sectional view in Fig. 1.
Block corner block during the high voltage power transmission construction that the present embodiment provides, including：Left standing frame 101, right standing frame 102,
Top sheave 103, lower sheave 104, clutch shaft bearing 105, second bearing 106；
The diameter of the top sheave 103 is more than the diameter of the lower sheave 104；
The top sheave 103 and lower sheave 104 are placed between the left standing frame 101 and right standing frame 102；
The top sheave 103 is fixed between the left standing frame and right standing frame by the clutch shaft bearing 105；
The lower sheave 104 is fixed between the left standing frame 101 and right standing frame 102 by the second bearing 106；
The upper ends bearing rope of top sheave 103；
Place danish seine rope in the space 107 formed between the top sheave 103 and lower sheave 104.
It is understood that place danish seine rope for convenience, the periphery of top sheave 103 and lower sheave 104 can be spaced pre-
Set a distance, i.e., the circumference of two pulleys are not in contact with.
Due to the coaster that the present embodiment provides, in order to avoid bearing rope in work progress and danish seine rope are mutually wrapped in one
Rise, top sheave 103 is set on the top of coaster, bottom sets lower sheave 104, i.e. top sheave 103 is arranged with lower sheave about 104
Row, can so make the distance at bearing rope and danish seine rope interval bigger, that is, the distance being spaced is about the straight of top sheave 103
Footpath.In addition, in order to further increase the distance of bearing rope and danish seine rope, the present invention sets top sheave to be more than lower sheave.Due to upper
The diameter of pulley directly determines the distance between bearing rope and danish seine rope, and lower sheave is only to play a part of slip.So may be used
To ensure that bearing rope and danish seine rope will not mutually be intertwined, so as to improve efficiency of construction.
In addition, coaster provided by the invention also includes：Upper hanging plate 108；
The upper hanging plate 108 is located at the top of the coaster；
One end of the upper hanging plate 108 is fixed on the right standing frame 102 by Fixed latches 109；
The other end of the upper hanging plate 108 is connected by movable latch 110 with the left standing frame 101；
Place the bearing rope in the space 111 that the top sheave 103 is formed with the upper hanging plate 108.
It is understood that set one end of upper hanging plate 108 to be connected by movable latch 110 with the left standing frame 101, can
To facilitate placement bearing rope.When needing to place bearing rope, the movable latch 110 is pulled up, upper hanging plate 108 is opened, specifically
Referring to Fig. 3, the figure is corresponding side view when upper hanging plate 108 is opened.
After bearing rope is placed, when the movable latch 110 inserts the left standing frame 101.
In addition, the coaster that the present embodiment provides, in addition to：Fixed tailing axle 112；
One end of the fixed tailing axle 112 connects the right standing frame 102, the other end connection institute of the fixed tailing axle 112
Left standing frame 101 is stated, for fixing the relative position of right standing frame 102 and left standing frame 101.
It should be noted that the material of the top sheave 103 provided by the invention and lower sheave 104 is nylon material.
It is steel that pulley in corner block of the prior art, which uses material, will so increase the abrasion to insulating cord.And
Two pulleys that the present invention uses are nylon materials, can so reduce the abrasion to bearing rope and danish seine rope.
The right standing frame 102 and left standing frame 101 use No. 10 channel-section steels, sturdy and durable.
The upper hanging plate uses Q345 steel.
The fixed tailing axle uses No. 45 steel.
The upper hanging plate is provided with through hole；
The coaster is hung on the cross-arm of power transmission tower using shackle through the through hole.
The coaster that above example of the present invention provides, two pulleys, and top sheave is big up and down are set, truckle is small, full
Sufficient construction property, it can increase the distance between bearing rope and danish seine rope, avoid both from being mutually wrapped in work progress
Together.In addition, for the ease of placing thicker bearing rope, upper hanging plate is arranged around to the form of Fixed latches activity.Due to
Danish seine rope is thinner, therefore can directly seal in the space 107 between top sheave and lower sheave.
Coaster provided by the invention can improve efficiency of construction, ingenious in design, and unheavy.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention.Though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention.It is any to be familiar with those skilled in the art
Member, without departing from the scope of the technical proposal of the invention, all using the methods and technical content of the disclosure above to the present invention
Technical scheme makes many possible changes and modifications, or is revised as the equivalent embodiment of equivalent variations.Therefore, it is every without departing from
The content of technical solution of the present invention, the technical spirit according to the present invention is to any simple modification made for any of the above embodiments, equivalent
Change and modification, still fall within technical solution of the present invention protection in the range of.
