Detailed Description
The invention is further described below with reference to the accompanying drawings. In the description of the present invention, it is to be understood that the terms "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations and positional relationships based on those shown in the drawings, and are used merely for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be taken as limiting the scope of the present invention.
As shown in the figure, a lifting platform comprises a work bucket 1 and a plurality of ladder stands 2 movably connected to the bottom of the work bucket 1, a fixing part 3 is arranged in the center of the bottom of the work bucket 1, a plurality of telescopic cylinders 4 in one-to-one correspondence with the ladder stands 2 are connected to the bottom of the fixing part 3, clamping claws 6 are arranged at the tail ends of telescopic arms 5 of the telescopic cylinders 4, and the clamping claws 6 can be connected with dowel bars 7 arranged on the ladder stands 2 in a buckling mode. Before the lifting platform is lifted, the telescopic arms 5 of the telescopic cylinders 4 are controlled to extend out, so that the clamping jaws 6 at the tail ends of the telescopic arms 5 are buckled on the dowel bars 7 of the corresponding ladder stands 2; the telescopic arms 5 are controlled to retract, the pulling force acts on the ladder stand 2 through the dowel bars 7, the ladder stand 2 approaches to the fixing piece 3 under the action of the centripetal pulling force, and then the ladder stand gradually stands up to realize lifting operation; after the lifting is finished, the lifting platform can be kept stable by depending on the self structure of the lifting platform, and an external power source is not required to do work additionally; the operation principle of the lifting platform during descending is similar to that during lifting, the telescopic arms 5 are controlled to extend out, the ladder stand 2 is pushed to be far away from the fixing piece 3, and the working bucket 1 descends. The position of dowel bar 7 can be adjusted according to actual need, because telescopic cylinder 4's length is invariable, so the distance of dowel bar 7 and mounting 3 also does not change when lifting to the highest point, has changed the position of dowel bar 7, just can change the angle range that cat ladder 2 stands, and then changes the height upper limit of work fill 1, has enlarged the application scope of whole lift platform.
As shown in fig. 1 and 2, in the present embodiment, the number of the ladder stands 2 is three, and the three ladder stands 2 are symmetrically arranged in a ring shape with a perpendicular bisector of the bucket 1 as a symmetry axis. Dowel bars 7 on the three crawling ladders 2 are arranged at the same height, and after the claws 6 are buckled on the dowel bars 7, the output power of the three telescopic cylinders 4 is kept the same, and the three telescopic arms 5 are also kept in the same motion state, so that the stable lifting of the working bucket 1 can be ensured. It should be noted that this embodiment is only a preferred embodiment created by the present invention, and in other embodiments, the number of the ladder stands 2 may be larger than three, the position and length of the ladder stands 2 may also be asymmetrically designed, and the output power of each telescopic cylinder 4 is adjusted to extend or retract each telescopic arm 5 at different movement speeds, so as to ensure stable lifting of the bucket 1, and the design solution also falls within the protection scope of the present invention.
As shown in fig. 2, the ladder 2 includes an insulating ladder tube 21 and a non-insulating ladder tube 22, the insulating ladder tube 21 is disposed at a side close to the working bucket 1, the insulating ladder tube 21 is made of glass fiber, and the non-insulating ladder tube 22 is made of a composite material containing carbon fiber and polyetheretherketone. The operation place of lift platform often the operating mode is complicated, may have the hidden danger of electrocuting, sets up insulating ladder pipe 21 back, can avoid whole lift platform to form a conducting path, sets up insulating ladder pipe 21, has cut off the conducting path between work fill 1 and the ground, even ground produces the danger of electrocuting, the staff on the work fill 1 can not meet with danger yet, has promoted whole lift platform's security performance.
The working bucket 1 is made of titanium alloy material, the firmness degree of the working bucket is ensured, and the fence protection effect can be fully exerted. The work bucket 1 is provided with an inclination angle monitoring and alarming device, if the lifting platform is in an accident in the working process, the work bucket 1 is unbalanced, the inclination of the work bucket is greater than the preset value of the inclination angle monitoring and alarming device, an alarm is triggered, and a worker is prompted to stop operating and take protective measures.
In this embodiment, the telescopic cylinder 4 is movably connected with the fixing member 3 in a hinged manner, and the telescopic cylinder 4 can be driven by the driving device to change the angle between the telescopic cylinder and the horizontal plane. After the telescopic arm 5 finishes contracting, the driving device is started, the telescopic cylinder 4 continues to swing downwards, the distance between the ladder stand 2 and the fixing piece 3 is shortened, the lifting upper limit of the working bucket 1 is further improved, and the application range of the lifting platform is expanded.
As shown in fig. 3, a bottom plate 8 is connected to the bottom of the ladder 2, a pressure sensor 9 is arranged between the bottom plate 8 and the ladder 2, and the pressure value applied to the bottom plate 8 by the ladder 0 can be monitored in real time through the pressure sensor 6. When the pressure value is too large, the vertical degree of the ladder stand 2 is relatively high, and the distance between the ladder stand 2 and the fixing piece 3 is too close, so that the stability of the whole lifting platform is influenced. The staff can monitor this pressure value, holds lift platform's lifting degree, avoids the risk.
The bottom plate 8 lower extreme is provided with gyro wheel 10, and when lift platform goes up and down, the slip displacement is realized to cat ladder 2 accessible gyro wheel 10, and the resistance is littleer, and whole device power consumption is also few, does benefit to the operation.
The bottom plates 8 are further provided with connecting holes 11, the connecting rods 12 are arranged among the bottom plates 8, and two ends of each connecting rod 12 are provided with connecting heads 13 matched with the connecting holes 11. After the lifting platform lifting is completed, the positions of the ladder stands 2 are not changed, the connecting rods 12 are adjusted to proper lengths, the connectors 13 are inserted into the connecting holes 11, the connecting rods 12 are fixed between the bottom plates 8, the distance between the ladder stands 2 can be stabilized, and the stability of the whole lifting platform is improved.
As shown in fig. 3 and 4, a height compensator 14 is further disposed in the center of the bottom plate 8, an adjusting knob 15 is disposed in the center of the height compensator 14, and a supporting foot 16 is connected to the bottom of the adjusting knob 15. After the lifting platform is stable, the adjusting knob 15 is rotated to control the supporting feet 16 to extend out until the supporting feet contact the ground, and the ladder stand 2 can be fixed. The working condition on the spot is complicated, and the regional ground that lift platform is located may not be level and smooth enough, through adjust knob 15, adjusts the extension length of each spike 16, can offset the influence that partial ground slope brought.
It will be apparent to those skilled in the art that various modifications may be made to the above embodiments without departing from the general spirit and concept of the invention. All falling within the scope of protection of the present invention. The protection scheme of the invention is subject to the appended claims.
