Description
Technical field
The utility model relates to power construction apparatus field, belong to for a kind of extending foot of cableway A-frame.
Background technique
Currently, transmission line of electricity increasingly develops to super-pressure, extra-high voltage direction, and these super-pressure, extra-high voltage are most
It is erected at the complex topographic territories such as no man's land, especially mountain area, forest land again, this brings the erection of transmission line of electricity very big
Inconvenience especially sets up these super-pressure, the goods and materials transport of UHV transmission line is made troubles；It needs first to add shipping thus
The electric transmission line erection of a large amount of heavy type is transported to the place of complicated landform by cableway with goods and materials, is set up and is transmitted electricity for power worker
Route is used；Freight ropeway includes at least both ends bracket, hauling rope, carrying rope, freight trolley and dragger at present, and some is also
Including intermediate support, stringing goods and materials are transported to stringing place to support hauling rope and carrying strap to move freight trolley.
Since freight ropeway carries the stringing goods and materials of larger volume and weight, in the more severe condition of the condition of erection
Under, consider it is more be the safety of cableway, wherein selecting how the ropeway supporting trestle of structure becomes key point, current cableway branch
Frame selects the simple door shaped stent of structure, can only be suitable for relatively flat ground of topographies such as city Plains since structure is simple
Side, for rugged just helpless up.
Utility model content
The purpose of the utility model is to provide a kind of extending foots of cableway A-frame, can effectively solve background technique
The problems in.
Realize above-mentioned purpose technical solution be: the extending foot of cableway A-frame, it is characterised in that: including mutually it
Between by the upper connector and lower connector of flanged joint, intermeshing first band is equipped with by bearing respectively in upper connector
Shaft bevel gears and second band shaft bevel gears, the first band shaft bevel gears, upper connector axial centre be vertically arranged, the second band
Shaft bevel gears, upper connector axial centre be arranged concentrically, the protruding upper connector of the rotation axis of first band shaft bevel gears；Institute
The inner tube for being provided with and being slided in lower connector with respect to lower connector is stated, the center of inner tube is threaded with screw rod, the screw rod
It is fixedly connected with the second band shaft bevel gears.
The utility model provides a kind of extending foot, can be by adjusting height, to adapt in rugged mountain area
A variety of different landform have extensive adaptability, have structure simple, easy to use, and security performance, which greatly improves, waits spies
Point.
Further, the lower end of said inner tube extends downwardly lower connector and is hinged with pedestal, and the setting of pedestal guarantees branch
Frame support is more steady.
Further, the outer end of the rotation axis of the first band shaft bevel gears is provided with the center for cooperating with rocking handle
Hole, convenient for passing through rocking handle rotating shaft, to adjust the height of telescopic outrigger.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of existing cableway A-frame.
Specific embodiment
As shown in Fig. 2, cableway A-frame in the prior art includes crossbeam 1, the both ends of crossbeam 1 are connected separately with triangle
Steel pipe support 2, triangle steel pipe support 2 include two and are arranged in two steel pipes in the first steel pipe supporting leg 3 of left and right arrangement and one
The upper end of the second steel pipe supporting leg 4 between supporting leg 3, the first steel pipe supporting leg 3 can swingingly be hinged on crossbeam along 1 width direction of crossbeam
On 1, the second steel pipe supporting leg 4 can be swingingly hinged on crossbeam 1 along 3 length direction of crossbeam.
It is connected under the first steel pipe supporting leg 3 and the second steel pipe supporting leg 4 as shown in Figure 1, the utility model provides one kind
The extending foot 5 at end, extending foot 5 include the upper connector 5.1 and lower connector 5.2 for passing through flanged joint between each other, on
Intermeshing first band shaft bevel gears 5.4 and the second band shaft bevel gears 5.5 are equipped with by bearing 5.3 respectively in connecting tube 5.1,
First band shaft bevel gears 5.4, upper connector 5.1 axial centre be vertically arranged, second band shaft bevel gears 5.4, upper connector 5.1
Axial centre be arranged concentrically, the protruding upper connector 5.1 of the rotation axis of first band shaft bevel gears 5.4 and outer end are arranged
There is a centre bore 5.9 for cooperating with rocking handle, centre bore 5.9 can be in the structure of polygon using section, in lower connector 5.2
It is provided with the inner tube 5.6 that can be slided with respect to lower connector 5.2, the lower end of inner tube 5.6 extend downwardly lower connector 5.2 and hinged
There is pedestal 5.8, the center of inner tube 5.6 is threaded with screw rod 5.7, and screw rod 5.7 is fixedly connected with the second band shaft bevel gears 5.5.
Cableway A-frame is in use, be triangularly arranged structural support on ground for the triangle steel pipe support 2 at 1 both ends of crossbeam
On face, and 5 length of extending foot of the first steel pipe supporting leg 3 and the second steel pipe supporting leg 4 is adjusted according to field condition, guarantee and ground
Firm contact, the specific Principles of Regulation of extending foot 5 are as follows: pass through rocking handle rotate first band shaft bevel gears 5.4, first band axial cone
Gear 5.4 drives the second band shaft bevel gears 5.5 to rotate, and the second band shaft bevel gears 5.5 drive screw rod 5.7 to rotate, and screw rod 5.7 drives
Inner tube 5.6 is gone up and down, to realize the height adjustment of the first steel pipe supporting leg 3 and the second steel pipe supporting leg 4.
