Detailed Description
The embodiment of the invention provides a climbing performance test platform of an insulating bucket arm vehicle, which is used for solving the technical problem that the development of the insulating bucket arm vehicle is limited due to the lack of the climbing performance test platform.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the embodiments of the present application, it should be noted that the terms "mounted," "connected," and "connected" are used broadly and are defined as, for example, a fixed connection, an exchangeable connection, an integrated connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, and a communication between two elements, unless otherwise explicitly stated or limited. Specific meanings of the above terms in the embodiments of the present application can be understood in specific cases by those of ordinary skill in the art.
Because of insulating boom car can provide good operating condition for high altitude live working, has been used widely in electric power system comprehensively, but the operational environment among the electric power system is complicated, mostly the mountain area, the topography is complicated, the operation vehicle can't avoid passing through complicated highway sections such as a large amount of abrupt slopes on the way, so whether need to possess the climbing ability that safely passes through various topography complicated ramps to professional operation vehicle before using and test, still report relevant insulating boom car and climb abrupt slope's test platform, design thinking and method, and do not have the complete vehicle parameter measurement system who matches with climbing abrupt slope test platform. Due to the lack of a test platform for the climbing of the insulating bucket arm truck, whether the climbing performance of the insulating bucket arm truck meets the specific operation requirement cannot be determined, and further the safe use of the insulating bucket arm truck and the perfection and development of the insulating bucket arm truck are limited.
Referring to fig. 1, fig. 1 is a platform for testing climbing performance of an insulation bucket arm vehicle according to an embodiment of the present invention.
The invention provides a climbing performance test platform of an insulating bucket arm vehicle, which comprises:
a test ramp 10, a first connecting ramp 20, a second connecting ramp 21, a first level 40 and a second level 41; the lower end of the test ramp 10 is connected with the first channel 40 through the first connecting ramp 20, and the higher end is connected with the second channel 41 through the second connecting ramp 21; the slope of the test ramp 10 is greater than the slope of the connecting ramp.
It should be noted that: the test ramp is an inclined ramp with equal gradient at each position on the ramp; the connecting ramp is an inclined ramp with equal gradient at each position on the ramp; the flat road is a road surface parallel to the horizontal plane; the first level road is a flat ground.
The insulating arm vehicle climbing performance testing platform in the embodiment is composed of a first flat road, a first connecting ramp, a testing ramp, a second connecting ramp and a second flat road which are sequentially connected from low to high, the gradient of the testing ramp is set to be the maximum gradient of the insulating arm vehicle required to pass through in an actual application environment, the connecting ramp is arranged to connect the testing ramp and the flat road, so that the insulating arm vehicles with different approach angles and departure angles can safely drive in and out of the testing ramp, and then the insulating arm vehicle to be tested drives from the first flat road to the second flat road to complete testing. If the insulating bucket arm vehicle can stably run through the test ramp, the climbing performance of the insulating bucket arm vehicle is judged to reach the standard; and if the insulating bucket arm vehicle cannot stably run through the test ramp, judging that the climbing performance of the insulating bucket arm vehicle does not reach the standard.
Specifically, through statistical analysis, the maximum gradient of most areas needing to be operated by the insulating bucket arm vehicle is found to be 28-44%, so that the gradient value range of the test ramp is determined to be 28-44%; the length of test ramp should not be too short, because need guarantee that insulating arm car wholly gets into test ramp back and then drives out from test ramp completely, otherwise can't embody the climbing performance of insulating arm car, need consider the energy saving in addition, so the length of test ramp should not set up too long yet, through the car length that combines current different model insulating arm cars and can embody the minimum distance of marcing of climbing ability, the length value scope of final definite test ramp is 10 ~ 16 meters. The sudden change by a wide margin of slope can cause the vehicle to take place contact or collision with the road surface, lead to the unable normal driving of vehicle, and the slope of test ramp is great, so can't let insulating arm car directly get into test ramp from the level road, so set up the connection ramp and couple together level road and test ramp, let insulating arm car drive in the first connection ramp of less slope from the first level road of 0 slope earlier, drive in the test ramp of big slope from the first connection ramp of less slope again, be equivalent to setting up a buffering slope, the sudden change range with the slope reduces. The test shows that when the gradient of the connecting ramp is about half of that of the test ramp, the head and the tail of the insulating arm car cannot contact or collide with the road surface, so that the gradient value range of the connecting ramp is 14% -22%, and meanwhile, in order to avoid sudden change of the advancing speed of the car caused by continuous and rapid increase of the friction force borne by the car, the length of the first connecting ramp is set to be equal to that of the test ramp, and the insulating arm car is driven into the test ramp after the advancing speed of the first connecting ramp is stable. Because when the vehicle drives into the second connecting ramp from the testing ramp and drives into the second flat road from the second connecting ramp, the friction force borne by the insulating arm vehicle is reduced, the speed can be increased, and the vehicle can normally drive without time for speed buffering, the second connecting ramp mainly has the effect of providing a buffering gradient between the testing ramp and the second flat road so as to ensure that the insulating arm vehicle can safely drive out of the testing ramp, the length of the second connecting ramp can be set to be shorter than that of the first connecting ramp, and the length range of the second connecting ramp is 7-10 meters.
Optimally, in order to enable the climbing performance test platform of the insulating arm vehicle to be generally applicable, in the embodiment, a value with the widest application range is selected in the value ranges of the slope gradient and the slope length of the slope, and the value ranges are combined to obtain a test platform with higher universality.
