Detailed description of the invention
The exemplary embodiments embodying feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various changes in different embodiments, it neither departs from the scope of the present invention, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit the present invention.
The hoisting crane of the embodiment of the present invention, has the walking auto-guider of the embodiment of the present invention; But walking auto-guider of the present invention, is not limited to just for hoisting crane, also may be used for the mechanical equipment that other walking arrangements are the straight line moving of wheel rail system.
Walking auto-guider below for hoisting crane is example, introduces the walking auto-guider of the embodiment of the present invention.
The walking auto-guider of the embodiment of the present invention, utilize be arranged on hoisting crane side, front and back end at least two cover guidance sets carry out work, guidance set preferably two cover, also can be four covers.Be introduced with the two cover guidance sets being installed on the front and back end of the side of hoisting crane.
Two rang sensors 3 measure certain side of hoisting crane 1, front and back end relative to the horizontal throw of orbit 7.If two distances measured remain unchanged or remain within the scope of setting in hoisting crane traveling process, illustrate that hoisting crane traveling track is straight line or is similar to straight line, traveling is good, without the need to adjustment.Further, from the horizontal throw that this is measured, also can find out drift condition and skew side, also namely to any side offset.
If two distances measured exceed the scope of setting in hoisting crane 1 traveling process, and trend is when being increasing, the straight line of the traveling track that hoisting crane is described more and more offset track, at this moment, control system automatic (or manual) instruction driver train 4 be arranged in two guide piecees of hoisting crane side, front and back end of hoisting crane promotes horizontal guide sheave 5 and moves a certain distance to skew side, under the effect of horizontal guide sheave 5, hoisting crane 1 moves towards the running orbit (straight line) specified gradually, so just achieves self guided effect.Below for crane in bridge type, be described in detail as follows:
As shown in Figure 1, the walking auto-guider of the embodiment of the present invention, can be arranged on the two ends of hoisting crane side, and as left side in Fig. 1, in Fig. 1, hoisting crane is such as that upwards skidding is sailed.
As shown in Figure 1 and Figure 4.Hoisting crane 1 is conventional crane in bridge type, usually includes 4 wheels 11; Bearing 2 has two, is fixedly mounted on the rear and front end on the left of hoisting crane 1 respectively, and support 2 includes slide rail 21 and the support 22 for mounting distance sensor 3.
Rang sensor 3 is arranged on support 22, track 7 inner side, and flush in vertical direction with track 7, rang sensor 3 can measure the horizontal throw with track 7 side, respectively has one before and after rang sensor 3.
Bearing 6 is mainly used to installation two horizontal guide sheaves 5, by the support 61 be fixed on bearing 6, two horizontal guide sheaves 5 are installed, be stuck on slide rail 21 by the slide rail bayonet socket 62 be fixed on bearing 6, make bearing 6 can along slide rail about 21 linear slide, bearing 6 has two, front and back end is arranged, also namely the bearing 6 of hoisting crane 1 front end is positioned at the front of bearing 2, and the bearing 6 of hoisting crane 1 rear end is positioned at the rear of bearing 2.
Two actuating devices 4, respectively arrange one before and after hoisting crane 1.Each actuating device 4, one end is hinged on bearing 2, and the other end is hinged on bearing 6, and bearing 6 can be driven relative to bearing about 2 linear slide; Two horizontal guide sheaves 5 are arranged on same support 61, and horizontal guide sheave 5 horizontal arrangement, flushes with track 7, be distributed in the left and right sides of track 7, can directional tagging be played, guide the route of being partial to regulation during hoisting crane 1 traveling, horizontal guide sheave 5 totally 4, divides two groups, is distributed in rear and front end; Track 7, for carrying hoisting crane 1, directly contacts with 4 wheels 11 of hoisting crane 1, and track 7 is straight line in theory.
Hoisting crane 1 is along before and after track 7 during traveling, running orbit is straight line in theory, but because the difference etc. of the difference of the straightness accuracy difference of the actual variance of wheel diameter, track body, orbit altitude, driving vehicle wheel rotational speed, hoisting crane 1 running orbit can be made to be not exclusively straight line, wheel rim and track even can be made to rub mutually or gnaw rail.When hoisting crane 1 runs, be arranged on the left of hoisting crane 1, two rang sensors 3 of front and back end can in real time with certain frequency measure respectively its at a distance of distance X1 (front), X2 (afterwards) of track, and by this data upload to the control system of hoisting crane, operating personal can understand the running state of hoisting crane relative to track in time.
When X1 is less than the limit value of setting, or X1 is in the trend reduced gradually to be had when exceeding limit value possible, the control system automatic (or manual) of hoisting crane sends instruction, the horizontal guide sheave 5 making actuating device 4 promote X1 end moves to the left, namely in Fig. 4, the right horizontal guide sheave in front end 5 diminishes with track 7 gap L 1 (in Fig. 4 the right horizontal guide sheave 5 in rear end and track 7 gap L 2) is even zero, progressively can reduce the value of X1 like this when hoisting crane runs, force hoisting crane traveling track to be tending towards normal; If X1 becomes large and exceed the limit value of setting, or the trend that X1 is in be increased gradually has when exceeding limit value possible, the control system automatic (or manual) of hoisting crane sends instruction, the horizontal guide sheave 5 making actuating device 4 promote X1 end moves to the right, namely the flat wheel in a left side, Fig. 4 Zhong Shui front end diminishes with orbit gap is even zero, progressively can reduce the value in this gap like this when hoisting crane runs, force hoisting crane 1 traveling track to be tending towards normal.In like manner, also can according to the situation of change of X2, adjustment rear end horizontal guide sheave 5 and the gap L 2 of track 7, adjust the running orbit of hoisting crane.In addition, also can adjust the right horizontal guide sheave 5 in front end and track 7 gap L 1 simultaneously, and the gap L 2 of rear end horizontal guide sheave 5 and track 7, reach the quick adjusting of operation track for crane.
It should be noted that:
1, above-described embodiment only arranges rang sensor 3 in track 7 side, also can arrange a pair rang sensor 3 in track 7 both sides, both can increase redundancy, and mutually can verify correctness again;
2, in Fig. 2, Fig. 3, actuating device 4 is a hydraulic actuating cylinder, may also be a cylinder, or motor-driven gear rack actuating device, or motor-driven worm and gear actuating device etc., as long as the actuating device of linear drives can be formed.
3, rang sensor 3 can be laser ranging, and also can be electromagnetic induction range finding, mainly own vol be little, survey precision is high.
The walking auto-guider of the embodiment of the present invention, solve the technical matters of the horizontally-guided foot wheel abrasion of hoisting crane, handled easily personnel understand hoisting crane traveling situation in real time, automatic adjustable level track adjusting wheel position, automatic calibration hoisting crane circulation line, reduces maintenance cost.
The change that those skilled in the art do when should recognize the scope and spirit of the present invention disclosed in the claim do not departed from appended by the present invention and retouching, within the protection domain all belonging to claim of the present invention.
