Abstract
The utility model discloses a high altitude construction car cantilever crane, include first cantilever crane cover, second cantilever crane cover, flexible hydro -cylinder, tow chain, first cantilever crane ways is established outside second cantilever crane cover, and first cantilever crane cover and second cantilever crane cover inside are had a perfect understanding, and flexible hydro -cylinder setting is in first cantilever crane cover and second cantilever crane cover, the inside tow chain holding chamber that is equipped with of first cantilever crane cover, flexible hydro -cylinder are close to first cantilever crane cover one end fixed connection tow chain, the tow chain holding intracavity of tow chain setting in first cantilever crane cover. The tow chain sets up in first cantilever crane cover, and waterproof, rain -proof can reduce the corruption, ageing of tow chain, has lengthened the life of car cantilever crane, and is simultaneously more pleasing to the eye.
Description
Technical field
This utility model is related to a kind of high-altitude operation vehicle jib structure.
Background technology
For the high-altitude operation vehicle of operation height relatively low (i.e. less than 25 meters), simple articulated boom structure is sufficient for
Its transaction capabilities requires, and the luffing stretching of jib structure drives drag chain to promote mainly by hydraulic jack.Existing market is existing
Drag chain on some boom type high-altitude operation vehicle arm supports is all fixing and external, less attractive in appearance and expose long in atmosphere
Time deposits easy corrosion, and wear phenomenon is serious.
Content of the invention
This utility model provides a kind of high-altitude operation vehicle arm support to solve of the prior art not enough, additional in principal arm
If arm support set, the burn into that waterproof, rain-proof can reduce drag chain is aging, extends the service life of car arm support, simultaneously more beautiful
See.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is：
A kind of high-altitude operation vehicle arm support, including the first arm support set, the second arm support set, telescopic oil cylinder, drag chain, the first arm support set
Be set in the second arm support set outer, the first arm support set and the second arm support set internal run-through, telescopic oil cylinder be arranged on the first arm support set and
In second arm support set；First arm support set is internal to be provided with drag chain containing cavity, and telescopic oil cylinder covers one end near the first arm support and is fixedly connected
Drag chain, the drag chain that drag chain is arranged in the first arm support set houses intracavity.Drag chain is arranged in the first arm support set, and waterproof, rain-proof can
Aging with the burn into of minimizing drag chain, extend the service life of car arm support, simultaneously better appearance.
As a kind of preferred version of high-altitude operation vehicle arm support described in the utility model, the first described arm support set and the
Two arm support inner rooms pass through slide block and supporting slide rail and connect, make arm support set become can with contraction type, according to the flexible situation of arm support,
To adjust the length of run of arm support set.
As a kind of preferred version of high-altitude operation vehicle arm support described in the utility model, fixing outside described telescopic oil cylinder
There is pressing plate, drag chain is fixed with pressing plate by bolt, convenient disassembly, when needing maintenance or changing drag chain it is only necessary to by bolt
Turn on it is possible to pull out whole piece drag chain.
As a kind of preferred version of high-altitude operation vehicle arm support described in the utility model, described the first arm support is by first
Upper arm support and second time arm support fasten formation up and down, and the second arm support is formed by fastening about the second left arm frame and the second right arm frame.

Specific embodiment
With reference to the accompanying drawings and detailed description this utility model is described in further detail.
Embodiment 1
As Figure 1-4, a kind of high-altitude operation vehicle arm support, including first arm support cover 1, second arm support set 2, telescopic oil cylinder 3,
Drag chain 4, the first arm support set 1 is set in outside the second arm support set 2, and the first arm support set 1 and the second arm support cover 2 internal run-throughs, and stretch oil
Cylinder 3 is arranged in the first arm support set and the second arm support set；First arm support set is internal to be provided with drag chain containing cavity, and telescopic oil cylinder 3 is close
First arm support covers one end and is fixedly connected drag chain 4, is fixed with pressing plate 6 outside telescopic oil cylinder 3, and drag chain 4 passes through bolt to be fixed with pressing plate 6,
Drag chain is arranged in the drag chain containing cavity 5 in the first arm support set.
Connected by slide block and supporting slide rail between the first arm support set 1 and the second arm support set 2, it is to avoid rigidity rubs.
For the ease of dismantling and overhauling, the first arm support is fastened up and down and is formed by arm support on first and second time arm support, and second
Arm support is formed by fastening about the second left arm frame and the second right arm frame.
As equipment has the phenomenons such as abrasion using rear drag chain for a long time, need maintenance, replace or maintain, as long as pressure will be fixed on
On plate, the bolt on both sides unclamps, linearly to the first arm support posterior joint pull out drag chain, very convenient practicality and
And whole set equipment seems very attractive in appearance.
Although being illustrated to embodiment of the present utility model in description, these embodiments are intended only as carrying
Show, should not limit protection domain of the present utility model.Carry out various omissions in the range of without departing from this utility model objective, put
Change and change should be included in protection domain of the present utility model.
