The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
Shown in Fig. 1 to 7, the link plate operating control of changing step according to the utility model embodiment, wherein, the link plate 30 of changing step is arranged on the stock 50 of hoisting crane, the link plate operating control of changing step comprises: the thrust unit 10 that is arranged on stock 50 1 sides, thrust unit 10 comprises rocking bar 11, center shaft 12 and impeller 13, first end of rocking bar 11 is connected with the top and bottom of center shaft 12 respectively with first end of impeller 13, second end of rocking bar 11 to the distance of center shaft 12 greater than second end of impeller 13 distance to center shaft 12; Wherein, impeller 13 is used for rotating with the link plate 30 of changing step contact and promote to change step link plate 30.
Whole device is laborsaving by lever principle, since as second end of the rocking bar 11 of the arm of force initiatively to the distance of center shaft 12 greater than as second end of the impeller 13 of resistance arm distance to center shaft 12, when therefore needing to promote to change step link plate, as long as use less power just can obtain Expected Results.Because thrust unit is arranged on a side of the stock 50 of hoisting crane, device gets up not take up space, and can handle the link plate of changing step in limited space, thereby finishes the operation of changing step of hoisting crane.The length of each parts of thrust unit all can specifically be provided with according to concrete needs, and the concrete length of center shaft 12 for example can highly be set according to operation.
As shown in Figure 1, also comprise the pin 20 that is fixed on the link plate 30 of changing step according to the link plate operating control of changing step of the present utility model, pin 20 contacts with impeller 13 and drive the link plate 30 of changing step under impeller 13 promotes and rotates.Preferably, pin 20 be arranged at the link plate 30 of changing step on the side of a side of thrust unit 10.
According to an embodiment of the present utility model, hoisting crane is superhuge tower crane.As shown in Figure 4 and Figure 5, change step link plate 30 in initial condition, because of the reason of gravity is in plumbness, the link plate 30 of changing step this moment hangs on the body of the tower joint main chord 60 of hoisting crane.When the tower machine need change step to operate, as shown in Figure 6 and Figure 7, inwardly stir rocking bar 11, rocking bar 11 drives impellers 13 outwards promote to change step pin 20 on the link plate 30 by center shaft 12, make the link plate 30 of changing step break away from body of the tower joint main chord 60 and outwards motion, thereby provide condition for finishing the operation of changing step.Pin 20 is arranged on changes step link plate 30 on the side of a side of thrust unit 10, thereby thrust unit 10 can adopt simple rod shaped structure just can realize promotion to pin 20.
As Fig. 1, Fig. 5 and shown in Figure 7, the link plate operating control of changing step comprises that also being fixedly connected on being used on the stock 50 hooks the grab 70 of rocking bar 11.
When rocking bar 11 reaches capacity the position, catch on rocking bar 11 with grab 70 and make rocking bar 11 be unlikely to outwards to move, thereby link plate 30 by gravitys that prevent to change step are fallen on body of the tower joint marks time in jacking or when falling joint.After hooking rocking bar 11 with grab 70, the link plate 30 of changing step breaks away from the body of the tower joint fully and marks time.When the tower machine need be hung when operation step, release catch 70, change step link plate 30 under the influence of gravity, rotate downwards, change step link plate 30 drives pins 20, and pin 20 promotes impellers 13 and inwardly moves, and impeller 13 outwards rotates center shaft 12, the link plate 30 that falls fully to changing step behind the position is fallen on the body of the tower joint marks time, for tower machine jacking supernumerary segment or fall tower and subtract joint and prepare.
As shown in Figure 1, the two ends of impeller 13 have bending part respectively, and are fixedly connected on the center shaft 12 by bending part.
The structure for amplifying of Fig. 1 shown in Fig. 2 and 3 also comprises otic placode 40 on the main chord 51 that is fixedly connected on stock 50 having the otic placode hole on the otic placode 40 according to the link plate operating control of changing step of the present utility model, and center shaft 12 passes the otic placode hole.
As shown in Figures 1 to 3, otic placode 40 comprises upper ear plate 41 and lower ear plate 42, and upper ear plate 41 is passed at the middle part of center shaft 12, and lower ear plate 42 is passed in the bottom of center shaft 12.
As shown in figures 1 and 3, the lower end of center shaft 12 has the locating part 121 that restriction center shaft 12 moves straight down with respect to lower ear plate 42.Preferably, locating part 121 is the hoop along the periphery of center shaft 12 along projection, and the overall diameter of hoop is greater than the diameter that is positioned at the otic placode hole on the lower ear plate 42.
Be positioned at the locating part 121 of center shaft 12 lower ends, the position that is used to limit center shaft 12 prevents that center shaft 12 from sliding from the otic placode hole of lower ear plate 42.The outside projection all around that locating part 121 can have any shape from center shaft 12, for easily manufactured, preferably, locating part 121 can be the hoop of diameter greater than the diameter in the otic placode hole on the lower ear plate 42, hoop can be in advance and center shaft 12 fix, the center shaft 12 that will have hoop then is placed in the otic placode hole of otic placode.
Preferably, upper ear plate 41 detouchables are connected with main chord 51.
This kind structure, on installation, the especially center shaft 12 of the link plate handling device that helps changing step have clip the time, can be earlier with in center shaft 12 suits and the upper ear plate 41, and then on mounting center axle 12, clip is installed.Perhaps, the otic placode hole on the upper ear plate 41 can be made the hole greater than the overall diameter of clip, make the center shaft 12 that has clip can pass upper ear plate 41, the upper ear plate 41 that will pass the center shaft 12 of strip slip-collar then is fixed on the main chord 51.
As can be seen from the above description, the utility model the above embodiments have realized following technique effect:
Adopt the link plate operating control of changing step of the present utility model, whole device is laborsaving by lever principle, when needing to promote to change step link plate, as long as use less power just can obtain Expected Results.Thrust unit is arranged on a side of the stock of hoisting crane, and device gets up not take up space, and reserves bigger operational space to the people, has strengthened the safety of work.In addition, this apparatus structure is simple, is easy to handle and install, and actv. has alleviated people's labour intensity, has improved the crane lifting supernumerary segment and has fallen the efficient that tower subtracts joint.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
