The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

Example one

As shown in fig. 1 to 3, the hoist according to the first embodiment includes a top frame 10, a guide post 20, a hoisting frame 30, and a hoisting device 40. Wherein the guide post 20 is provided on the upper frame 10 and extends toward the lower side of the upper frame 10. The guide post 20 is configured in a telescopic structure, and the guide post 20 is plural. The lifting frame 30 is attached to the end of the plurality of guide posts 20 facing away from the top frame 10. The lifting means 40 is adapted to move the lifting frame 30 closer to or away from the upper frame 10.

With the technical solution of this embodiment, the guiding column 20 of the hoisting machine is a telescopic structure, and the hoisting frame 30 is disposed at the lower end of the guiding column 20. During operation, the lifting device 40 may move the lifting frame 30 upward and retract the guide post 20. At this time, the lifting frame 30 can be lifted to a higher height and avoid the space below, so that the lifter can rotate to other stations for operation through the curing kiln. The structure can greatly expand the operation range of the hoister and improve the utilization rate of the hoister, so the technical scheme of the embodiment overcomes the defects that the hoister in the prior art is poor in utilization rate and can only operate in a small range.

The above-mentioned "the guide post 20 extends downward of the upper frame 10" means that the guide post 20 extends toward a lower space where the upper frame 10 is located when the hoist is placed on the track. When the elevator is placed in another position, the guide posts 20 extend outward relative to the top frame 10.

It should be noted that, in order to ensure that the lifting frame 30 can be lifted and lowered smoothly, the number of the guide posts 20 is set to be plural. Specifically, in the present embodiment, the number of the guide posts 20 is four, and the lower ends of the four guide posts 20 are respectively connected to four corners of the lifting frame 30. Of course, other numbers of guide posts 20 may be provided.

Further, the bottom end of the guide post 20 is connected to the lifting frame 30 by a fastener. Of course, the bottom ends of the guide posts 20 may be connected to the lifting frame 30 in other ways, such as by welding.

As shown in fig. 2, in the technical solution of the present embodiment, the lifting device 40 includes a hoisting mechanism, and the hoisting mechanism is connected with the lifting frame through a connecting rope. Specifically, when the hoisting mechanism tightens the connection rope, the connection rope applies upward tension to the lifting frame 30, and since the guide posts 20 are provided in a collapsible structure, the connection rope can lift and move the lifting frame 30 upward. At this time, the lifting frame 30 may move to a higher position, and as will be understood by those skilled in the art with reference to fig. 2, when the lifting frame 30 moves to the higher position, the guide pillar 20 does not interfere with the lower space of the lifting frame 30, so that the lifter may cross the production equipment (e.g., a curing kiln) and be circulated to other stations for working, thereby greatly improving the application range and utilization rate of the lifter. Accordingly, when the winding mechanism loosens the connecting rope, the lifting frame 30 is lowered by its own weight while the guide post 20 is extended.

As shown in fig. 2 and 4, in the solution of the present embodiment, the guiding column 20 includes a plurality of columns 21, and adjacent columns 21 are nested. Specifically, each guide post 20 in the present embodiment is constituted by three posts 21. The three columns 21 are nested in the vertical direction. Further, the column body 21 is a hollow column, and the size of the column body 21 is gradually reduced in the direction from top to bottom, thereby enabling the column body 21 located below to penetrate upward into the column body 21 located above. The above structure allows the guide post 20 to be flexibly extended and contracted.

Of course, the structure (e.g., number) of the above-mentioned columns 21 can be adjusted by those skilled in the art, as long as the adjacent columns 21 can be nested.

As shown in fig. 4, in the solution of the present embodiment, a guiding structure 50 and a limiting structure 60 are disposed between adjacent columns 21. Specifically, in the present embodiment, the bottom of the inner wall of the upper column 21 is provided with a first roller, and the top of the outer wall of the lower column 21 is provided with a second roller. When sliding between the adjacent columns 21, the first roller and the second roller can function as a guide, i.e., as a guide structure 50. Further, when the adjacent columns 21 slide until the first roller and the second roller contact, the two columns 21 can no longer extend relatively, i.e. the first roller and the second roller also serve as the limiting structure 60.

Of course, the guide structure 50 and the position limiting structure 60 may be separate structures, and various common guide and position limiting structures may be adopted. For example, the guide structure 50 may be a guide groove and a guide rib, and the position-limiting structure 60 may be a position-limiting flange, etc.

As shown in fig. 2, in the solution of the present embodiment, the side of the lifting frame 30 is provided with a grabbing structure 70. Specifically, the gripping structure 70 is a jaw, which is disposed on both sides of the lifting frame 30, and each side of the lifting frame 30 is provided with a plurality of jaws. The jaws are controlled by air cylinders and can be opened outwardly or tightened inwardly so that the jaws can pick up the die table (or other component).

Further, rollers and drive wheels are provided on the inside surfaces of the jaws for horizontally transporting the die table (or other member) to a predetermined station.

As shown in fig. 3 and 4, in the technical solution of this embodiment, the elevator further includes a first traveling mechanism 80 and a second traveling mechanism 90 disposed on the top frame 10, and the first traveling mechanism 80 and the second traveling mechanism 90 are respectively adapted to cooperate with rails in different directions. The first traveling mechanism 80 and the second traveling mechanism 90 each include a roller and a motor that drives the roller to rotate. The first running gear 80 and the second running gear 90 make it possible to circulate the elevator in different directions in the production line.

As shown in fig. 3, in the present embodiment, the hoist further includes a position adjustment mechanism 100, and the position adjustment mechanism 100 is disposed between the top frame 10 and the first traveling mechanism 80. Specifically, the position adjustment mechanism 100 is a drive cylinder that can adjust the downward height of the first travel mechanism 80. As will be understood by those skilled in the art in conjunction with fig. 5 and 6, when the first traveling mechanism 80 has a lower height than the second traveling mechanism 90, the first traveling mechanism 80 is separated from the corresponding rail and the second traveling mechanism 90 is in contact with the corresponding rail. Accordingly, when the downward height of the first travel mechanism 80 is greater than that of the second travel mechanism 90, the first travel mechanism 80 contacts the corresponding rail and the second travel mechanism 90 is separated from the corresponding rail. Therefore, the position adjusting mechanism 100 can realize the switching of the hoister between different tracks.

Of course, the position adjustment mechanism 100 may be provided in other manners, and for example, the position adjustment mechanism 100 may be provided between the second travel mechanism 90 and the top frame 10. Alternatively, the above-described position adjusting mechanisms may be provided between the top frame 10 and the first traveling mechanism 80, and between the second traveling mechanism 90 and the top frame 10.

Example two

In contrast to the first embodiment, the lifting device 40 of the second embodiment is disposed between the adjacent columns 21, and the lifting device is adapted to relatively extend or retract the adjacent columns 21. The lifting device is a driving cylinder, the driving cylinder is arranged between the adjacent columns 21, and the driving cylinder can drive the adjacent columns 21 to relatively extend or retract, so that the effect of lifting or descending the lifting frame 30 is achieved.

In a new step, the winding mechanism may not be provided in the second embodiment.
