It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
As shown in fig. 1-4, an embodiment of the present invention provides a crane slipper for automatically plugging and unplugging a pin, including: the device comprises a sliding shoe beam 1, a push-pull trolley 2, a sliding rail 3, a track beam 4 and a track baffle 5;
the two slide rails 3 are arranged on the track beam 4 in parallel; a plurality of track baffles 5 are uniformly arranged on the outer sides of the two slide rails 3.
At least one group of push-pull trolleys 2 and sliding shoe beams 1 are arranged on the sliding rail 3 in a sliding mode; the push-pull trolley 2 is connected with the sliding shoe beam 1 through an oil cylinder 6; the push-pull trolley 2 is connected with the skid shoe beam 1 through a telescopic rod of the oil cylinder 6. The push-pull trolley 2 pushes the sliding shoe beam 1 to move so as to drive the whole running mechanism to slide on the sliding rail 3.
The skid shoe beam 1 bears the weight of the whole circular track crane and drives the running mechanism to run. The slipper beam 1 comprises a beam structure 11; sliding plates 12 are respectively arranged at two ends of the bottom of the beam structure 11; the skid plate 12 is mounted at the bottom of the beam structure 11 by means of socket head cap screws and a fixing plate. The sliding plate 12 is matched with the sliding rail 3; at least one end of the beam structure 11 is provided with an oil cylinder lug plate 13, and the oil cylinder lug plate 13 is used for being connected with the oil cylinder 6. The beam structure 11 is a main body of the slipper beam 1 and is mainly formed by welding plates. The sliding plate 12 is made of No. 45 steel plates, surface quenching is performed, material hardness is improved, and when the sliding shoes run, friction force between the sliding plate and the sliding rails can be reduced. The oil cylinder ear plate 13 is used for connecting a telescopic rod of the oil cylinder 6. The middle of the beam structure 11 is provided with a mounting hole, and the mounting hole is used for fixedly mounting a workpiece on the beam structure 11.
The push-pull trolley 2 pushes or pulls the sliding shoes to slide on the sliding rails through the extension and contraction of the oil cylinder 6. The push-pull trolley 2 comprises a trolley frame 21; the trolley frame 21 is generally made of steel plates by welding and bolting. The middle part of the trolley frame 21 is provided with an oil cylinder 6; the oil cylinder 6 is arranged in the middle of the trolley frame 21 through an oil cylinder pin shaft 26 arranged on the cylinder barrel, so that the oil cylinder 6 can rotate around the vertical direction, namely can swing in the horizontal direction, and the whole system is driven to move back and forth through the extension of the oil cylinder 6. The first lug plate 22 and the second lug plate 27 are sequentially arranged at the upper end and the lower end of the push-pull trolley 2; two sets of plugging pin shaft units are respectively arranged at two ends of the trolley frame 21; at least one roller 25 is arranged between the two sets of plugging pin shaft units; the utility model discloses can set up two gyro wheels 25 between two sets of plug round pin axle units.
The two sets of plugging pin shaft units are divided into front and rear plugging pin shaft units, and the front plugging pin shaft unit is close to the extending end of the telescopic rod of the oil cylinder; plug round pin axle unit includes: the plug pin electric cylinder 23, the plug pin shaft 24 and the support frame 28;
the plug pin electric cylinder 23 is mounted on the first ear plate 22 through a support frame 28; the supporting frame 28 is mounted on the first ear plate 22 through bolts; the telescopic rod of the plug pin electric cylinder 23 is connected with the plug pin shaft 24; the telescopic rod of the plug pin electric cylinder 23 is connected with the plug pin shaft 24 through a bolt; the plug pin 24 penetrates the first lug 22.
The plug pin 24 penetrates the second lug plate 27.
In order to ensure that the plug pin shaft 24 can clamp the push-pull trolley 2, the plug pin shaft 24 is not inserted into a certain pin hole of the slide rail system, but is clamped on a rail baffle plate outside the slide rail 3. The roller 25 is pressed on the upper plane of the side plate of the sliding rail 3, and the push-pull trolley 2 can move along with the sliding shoes on the sliding rail 3. When the plug pin electric cylinder 23 acts, the plug pin shaft 24 at the front end extends or contracts. When the plug pin shaft 24 is in the extending state, the plug pin shaft extends out of the lower surface of the second lug plate 27 by a proper distance to clamp the track baffle 5. In the contraction state, the plugging pin shaft 24 at the front end contracts to the upper surface of the second lug plate 27, so that the push-pull trolley 2 can move forwards on the slide rail 3.
As shown in fig. 5, in order to reduce the shaking of the oil cylinder 6 during the stretching process, the 4 sets of the plugging and unplugging pin shaft units do not act simultaneously, for example, if the forward direction is defined as forward, only two plugging and unplugging pin shafts at the front end are plugged and unplugged, and the other two electric cylinders do not act, when the oil cylinder 6 extends out, the plugging and unplugging pin shafts 24 are clamped on the slide rail baffle, and the oil cylinder 6 pushes the sliding shoes to move forward, so that the push-pull trolley 2 is in a pulled state as a whole.
Fig. 6 is a schematic view of the continuous motion of the operating mechanism. When a plurality of groups of push-pull trolleys and slipper beams are arranged on the slide rail 3, the push-pull trolleys and the slipper beams are sequentially arranged. For example, when two sets of the push-pull trolleys 2 and the skid shoe beams 1 are arranged, the two push-pull trolleys 2 enable the two oil cylinders 6 to alternately extend and retract through a control system. When the front end push-pull trolley 2 oil cylinder 6 extends out, the plug pin shaft 24 extends out to clamp the track baffle 5, the rear end push-pull trolley plug pin shaft 24 is in a withdrawing state at the moment, and the running mechanism moves forwards. After the oil cylinder of the front end push-pull trolley 2 is contracted, the plug pin shaft is retracted, meanwhile, the plug pin shaft of the rear end push-pull trolley extends out to clamp the track baffle, and the telescopic rod of the oil cylinder extends out to push the running mechanism to continue to move forwards. The two push-pull trolleys are pushed alternately to realize the continuous motion of the running mechanism.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: it is to be understood that modifications may be made to the technical solutions described in the foregoing embodiments, or some or all of the technical features may be equivalently replaced, without substantially departing from the scope of the technical solutions of the embodiments of the present invention.
