The specific embodiment
The invention will be further described below in conjunction with specific embodiments and the drawings, but should not limit protection scope of the present invention with this.
With reference to figure 1, the crawling equipment of the present embodiment comprises sliding trolley 11 and ratchet crawling device 12, links to each other by the oil cylinder 13 of creeping between the two.Sliding trolley 11 and ratchet crawling device 12 all are arranged on the track 14, are provided with a plurality of orbit holes of arranging side by side along the track bearing of trend on the track 14, and the ratchet in the ratchet crawling device 12 can insert orbit hole or therefrom deviate from.Wherein, the oil cylinder 13 of creeping can be any one suitable oil cylinder, for example hydraulic jack.
As a nonrestrictive example, sliding trolley 11 is connected with 2 ratchet crawling devices 12, and each ratchet crawling device 12 links to each other with sliding trolley 11 by the oil cylinder 13 of creeping respectively.
Referring to figs. 2 to Fig. 5, the ratchet crawling device in the present embodiment comprises: slipping mechanism bearing 1 is provided with spindle hole, spacing hole 15 and retreat spacing hole 16 advances on it; Main shaft 4 penetrates the spindle hole on the slipping mechanism bearing 1, and the setting party of this main shaft 4 is to perpendicular to the direction of creeping, namely perpendicular to the bearing of trend of track, as a nonrestrictive example, the end of main shaft 4 can be equipped with axle clamping plate 8, and 8 pairs of main shafts of axle clamping plate 4 carry out spacing; Ratchet 2, around main shaft 4 rotation, ratchet 2 comprises the main part 20 that is fixedly connected with main shaft 4 and certainly this main part ratchet top 21 that stretch out both sides about in the of 20 and ratchet bottom 22, particularly, has centre bore on the main part 20, main shaft 4 passes this centre bore; Ratchet shelves axle 3 penetrates removably and advances spacing hole 15 and retreat spacing hole 16, and ratchet shelves axle 3 is spacing to ratchet top 21 when this main shaft 4 rotates at ratchet 2; Anti-lifting shaft 7 penetrates the anti-lifting shaft hole on the slipping mechanism bearing 1, and the setting party of this anti-lifting shaft 7 namely is parallel to the bearing of trend of track to being parallel to the direction of creeping; The anti-piece 5 that rises can be around anti-lifting shaft 7 rotations, and this anti-end that rises piece 5 has the hook portion for the fastener track; The anti-pin 6 that upgrades removably passes anti-rises piece 5 and slipping mechanism bearing 1, with anti-rise piece 5 spacing be fixed on the slipping mechanism bearing 1 and make prevent rising piece 5 the hook portion fastener in orbit.
Below in conjunction with Fig. 1 to Fig. 5 the operating principle of this crawling equipment and ratchet crawling device is described.
When ratchet shelves axle 3 is positioned at when advancing spacing hole 15, ratchet 2 can be around main shaft 4 rotation (among Fig. 2 for being rotated counterclockwise), the ratchet bottom 22 of ratchet 2 is positioned at the rail groove on the track 14 under the original state, when stretching out, the oil cylinder 13 of creeping promotes 12 reaches of ratchet crawling device, ratchet 2 rotates so that ratchet bottom 22 can be deviate from rail groove around main shaft 4, whole ratchet crawling device 12 is promoted further to move forward by the oil cylinder 13 of creeping, and ratchet bottom 22 is because gravity can fall in the next rail groove automatically; The oil cylinder 13 of creeping this moment is regained, because the position-limiting action on 3 pairs of ratchet tops 21 of ratchet shelves axle, ratchet bottom 22 is stuck in the rail groove to deviate from rail groove, also just so that ratchet crawling device 12 be stuck on the rail groove, 11 withdrawals along with the oil cylinder 13 of creeping of sliding trolley that are installed in oil cylinder 13 other ends of creeping travel forward, this moment, ratchet bottom 22 sidewall was blocked by the sidewall of rail groove, and can guarantee that ratchet crawling device 12 is fixing provides pulling force for sliding trolley 11 in orbit.
When ratchet shelves axle 3 is positioned at when retreating spacing hole 16, the ratchet bottom 22 of ratchet 2 is positioned at the rail groove on the track 14 under the original state, when the oil cylinder 13 of creeping stretches out, because 3 pairs of ratchet tops 21 of ratchet shelves axle spacing so that ratchet bottom 22 be stuck in the rail groove, ratchet 2 can't be deviate from rail groove, namely ratchet crawling device 12 is stuck on the rail groove, be installed in 11 backward motions of stretching out along with the oil cylinder 13 of creeping of sliding trolley of oil cylinder 13 other ends of creeping, this moment, ratchet bottom 22 sidewall was blocked by the sidewall of rail groove, and can guarantee that ratchet crawling device 12 is fixing provides thrust for sliding trolley 11 in orbit; When the oil cylinder 13 of creeping is regained, ratchet 2 can be around main shaft 4 rotation (among Fig. 2 for turning clockwise), so that successfully deviate from rail groove ratchet bottom 22, ratchet crawling device 12 is mobile backward under the tractive of oil cylinder 13 of creeping, ratchet 2 is owing to gravity can fall automatically, so that ratchet bottom 22 falls in the next rail groove.
Furthermore, for the ratchet bottom 22 of ratchet 2 can fall in the rail groove smoothly, the weight of ratchet bottom 22 is much larger than the weight on ratchet top 21.In order to guarantee the weight difference of the two, the size of ratchet bottom 22 can be greater than the size on ratchet top 21, in addition can also be on ratchet top 21 flutings with weight reduction.
When running well, the anti-pin 6 that upgrades penetrates in the anti-installing hole that rises on piece 5 and the slipping mechanism bearing 1, so that the anti-hook portion fastener that rises piece 5 in orbit, with the maintenance posture.Turn to or other reasons when the ratchet crawling device is taken off from track at needs, the pin 6 of preventing upgrading can be taken off, pulling the anti-piece 5 that rises makes it around anti-lifting shaft 7 rotations, the ratchet crawling device is taken off from track, when commutation, the ratchet crawling device that takes off can be prevented on the orbital direction after the change, the pin 6 of will preventing again upgrading installs, so that anti-rises piece 5 and slipping mechanism bearing 1 is fixed.
The mounting means of whole ratchet climbing mechanism is as follows: the centre bore on the main part 20 of the oil cylinder otic placode of will creeping, ratchet 2 aligns with the spindle hole of slipping mechanism bearing 1, the main shaft 4 of packing into; To prevent again rising the anti-lifting shaft 4 of piece 5 usefulness and be connected with slipping mechanism bearing 1, spliced all parts will be wholy set in the track relevant position, insert again the anti-pin 6 that upgrades, finish installation.
Although the present invention with preferred embodiment openly as above; but it is not to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can make possible change and modification, so protection scope of the present invention should be as the criterion with the scope that claim of the present invention was defined.
