Description

  The present invention relates to a net lifting / lowering device for partitioning a space such as a cage in a cage or the like for breeding and managing birds and small animals.

When artificially rearing rare animals and rare bird species, nesting, breeding, breeding, flying and avoiding natural enemies are made so that their growth environment is as close as possible to natural conditions so that they can become independent and survive in the natural world. Attempts have been made to return the animals to nature.
In fact, in a large cage that is surrounded by a wire mesh, you can create various environments such as trees, water and rocks that mimic nature, and animals can have various experiences and training. , To breed.

Even in such cages that simulate nature, it may be necessary to bred animals at different stages in multiple spaces depending on the level of training.
For example, in the case of a bird, it may be necessary to make the growth space different between a stage of a chick that is still difficult to get out of the nest and a bird grown at the stage of flight training.

In order to partition such a space, the net is used as a partition, and when the partition is necessary, it is lowered to partition the space, and when the partition is unnecessary and the inside of the cage is used as a large space, the net may be raised. It is done.
When lifting and lowering a net, it is necessary to lift the net evenly over the entire length in the width direction so that the net can be lifted without entanglement.

However, unlike the curtains used on the stage, cages for raising such animals are equipped with mountains and valleys that imitate nature in the space. Depending on the location, the height from the ceiling or roof to the ground may be different.
In other words, the height of the net also varies depending on the location such as the topography, and the length of the rope for lifting the net also varies.
As described above, in order to pull up the net evenly, it is necessary to wind up ropes of different lengths, and in order to wind up the ropes of different lengths and uniformly raise the overall length in the width direction of the net, the drum of one diameter It is impossible to wind up the whole evenly.
In order to wind up ropes of different lengths, it is necessary to wind them separately using a plurality of winding drums, and the number of winders has increased.

  The problem to be solved is to be able to pull up the entire net even when the length of the rope to be wound is different, and to reduce the number of lifting devices that wind up the rope and lift the net. .

The lifting device for the partition net according to the present invention is suspended from the roof or the ceiling, and the partition net that partitions the cage interior space formed between the undulating ground and the roof or the ceiling. A lifting device for a partitioning net comprising a winch for winding a plurality of lifting ropes on a drum and lifting and lowering the partitioning net by winding or feeding the lifting rope, the winch drum having different diameters in multiple stages, The ends of a plurality of lifting ropes arranged at intervals over the entire partition net that can land on the ground are fixed to the lower end of the partition net, and the lower end of the partition net is landed along the ground. A plurality of lifting ropes having the same net hanging height at the position are connected to one, and the ascending rope connected to one according to the net hanging height. Connect multiple ropes in descending order of the net lifting height at the position where the lower end of the partition net is landed along the ground, and rotate the drum from the larger diameter of the winch drum to the smaller diameter. Then, all the lifting ropes are wound or sent out, and the net is lifted and lowered evenly.
It is also possible to arrange a longitudinal net extending in a direction intersecting with the above-described net and to be able to move up and down by a lifting device.

The present invention can obtain the following effects.
<a> Ends of a plurality of lifting ropes arranged at intervals over the entire partition net that can land on the ground having undulations are fixed to the lower end of the partition net, and the lower ends of the partition net are aligned with the ground. Since a plurality of lifting ropes having the same net hanging height at the landing position are connected to one, the number of ropes to be wound is reduced, and the configuration as a lifting device is simplified.
<B> The position where the diameter of the drum of the winch is varied in a plurality of stages, and the plurality of the lifting ropes connected to one according to the suspension height of the net are landed with the lower end of the partition net along the ground. Since the net suspension height in the order is high, the winch drum is connected from the largest to the smallest diameter, and the drum is rotated to wind up or send out all the lifting ropes so that the nets are evenly raised and lowered smoothly. The net can be lifted and lowered.
<C> A plurality of ropes can be wound and delivered by one lifting device, and the number of lifting devices can be reduced.
By making the longitudinal net move up and down in the intersecting direction with respect to the net partitioning the <d> space, the space partitioned by the net can be further partitioned.

  Embodiments according to the present invention will be described in detail below with reference to the drawings.

<1> Cage FIG. 2 is an overall view of the cage 1 for breeding rare bird species. The roof 3 is formed by a steel frame, front and rear surfaces 4 and 4, and left and right surfaces 5 and 5 are rhombuses. Wire mesh 2 is stretched.
The cage 1 is built on topography where the left and right end portions are raised, and the roof portion is inclined on the left and right end portions side.
Accordingly, the height from the topography of the cage 1 to the roof is different between the left and right intermediate portions and the left and right end portions, and the height gradually increases toward the end portions on the left and right end portions. It is low.
Such an internal space of the cage 1 can be partitioned by a net 6 that can land on the ground having undulations traversing left and right at positions spaced apart from each other in the front and rear directions.
In the embodiment, three nets 6 can be moved up and down, and the space in the cage 1 can be divided into four.
As the net 6, a net made of synthetic resin can be used.

<2> Rope The net 6 is hung from a steel plate that is a roofing material that extends to the roof 3 in the left-right direction, and can be moved up and down by a plurality of ropes 8 extended from a winch 7 disposed outside the cage 1. It has become.
The rope 8 can be widely used, such as a twisted synthetic resin fiber or a metal wire rope.
Each rope 8 is suspended from the roof portion 3 and fixed to the lower end portion of the net 6 by, for example, binding its tip.
Above the lower end of the rope 8, it passes through the mesh of the net 6 in some places and is not fixed to the net 6.
Alternatively, the rope 8 may be passed through a metal ring or string-like ring that is fixed to the net 6 at an appropriate distance from above and below.
As described above, the suspension height of the net 6 varies depending on the position in the left-right direction. Therefore, the winding length varies depending on the length of the rope 8 that moves up and down.
As shown in FIG. 1, the middle part of the net 6 has the highest hanging height (length to be pulled up), and the four longest ropes 8 a are lowered from the roof part 3 and fixed to the lower end part of the net 6. Has been.
As it goes from the middle part to the left and right, the suspension height of the net 6 gradually decreases, and the lengths thereof become shorter in the order of 8b, 8c, and 8d.

<3> Rope Connection The rope 8 having the same winding length, i.e., the net 6 hanging height at the position connected to the net 6, is integrally connected.
The four ropes 8a in the middle part are the ropes 8 that wind up the highest part of the net 6 and have the same winding length, and these are connected to one as shown in FIG. .
Of the rope 8, the rope 8b and the rope 8b have the same length for winding up and down as they go gradually from the middle to the left and right, and the rope 8c and the rope 8c, and the rope 8d and the rope 8d are the same. is there.
These ropes 8 having the same winding length are connected to each other as shown in FIG.

<4> Winch The winch 7 has a drum 11 on the outer periphery of the rotating shaft 10 rotated by the motor 9, and the diameter of the drum 11 is varied in a plurality of stages.
In the embodiment, since the winding length of the rope 8 is different in four stages, the diameter of the drum 11 is four stages.
The diameter ratio of the four stages of drums 11a, 11b, 11c, and 11d is the same as the ratio of the winding lengths of the ropes 8a, 8b, 8c, and 8d fixed to the net 6 to be pulled up.
Of the ropes 8, the rope 8 a having the longest winding length is connected to the drum 11 a having the largest diameter among the drums 11, and the ropes 8 b, 8 c, and 8 d have diameters in order as the winding length is shortened. Connect to small drums 11b, 11c, 11d.
This conceptual diagram is shown in FIG.
The winch 7 may be manually operated without using the electric motor 9.

<5> Longitudinal Net The net 6 described above crosses the cage 1 in the left-right direction and partitions the space, but the net 12 is also arranged in a direction intersecting the net 6, that is, in a direction longitudinally crossing the cage 1. It may go up and down to further partition the partitioned space.
In this embodiment, since the vertical height of the longitudinal net 12 is the same in the longitudinal direction of the cage 1, the lengths of the three ropes 8e connected to the vertical net 12 are all the same.
The three ropes 8e are connected to one and connected to a manual winch 13 having a single diameter.
The conceptual diagram of the connection state of the ropes 8a to 8e described above to the winches 7 and 13 is shown in FIG.

<6> Net lifting / lowering The motor 9 is driven to wind or send out the rope 8.
The ropes 8a to 8d are connected to the drums 11a to 11d having a larger diameter in the descending order of the winding length, and the drum 11 having a larger diameter winds a lot of the rope 8 even at the same rotation speed. Since the drum 11 having a diameter winds the rope 8 little by little, the entire length in the left-right direction of the net 6 is lifted and lowered equally according to the suspension height.
Since the lower end of the rope 8 is fixed only to the lower end portion of the net 6, the net 6 is pulled up rather than wound up.
Since the net 6 is lifted and lowered evenly, the net 6 can be lifted and lowered smoothly.

<7> Elevation of Vertical Net The vertical net 12 is raised and lowered using the winch 13.
The left and right ends of the net 6 and the left and right surfaces 5 and 5 of the cage 1 are formed by passing the string through the mesh and sewing it up and down, or by tying the string attached to one side to the other, Make sure there is no gap between them.
The net 6 and the longitudinal net 12 are also sewed in the vertical direction by passing the string through the mesh of the both, or by tying the string attached to one side to the other so that no gap is generated between them. To do.
