In the prior art, the enclosing mode is almost that the film is bound on a machine table by manually ascending a height. The enclosing mode of manual ascending and binding is adopted, and the defects of long time consumption, high construction difficulty, high danger, difficult fixation on a machine table, messy appearance and the like exist.

SUMMERY OF THE UTILITY MODEL

Based on the aforesaid is not enough, this application provides a enclose car to improve partly or totally, even solve among the relevant art and enclose the problem that the degree of difficulty is high and the effect is poor.

The application is realized as follows:

examples of the present application provide a bounding vehicle for bounding a work area; the car of enclosing includes:

the film take-up and pay-off mechanism comprises a scroll and a film wound on the scroll;

the limiting mechanism comprises at least three groups of brackets; each group of brackets comprises two supporting pieces, and each supporting piece comprises a clamping plate, a supporting plate and a movable block; one end of the supporting plate is connected with the lower end of the clamping plate, and the supporting plate is provided with a supporting surface for supporting in the operation area; two sides of the supporting plate are respectively movably connected with movable blocks, and the two movable blocks are selectively staggered or arranged in parallel with the supporting plate; the two movable blocks are arranged alternately with the support plate to be supported in the working area, and the two holding plates are provided to form a first gap so that the film drawn from the reel passes through the first gap.

In the implementation process, the film winding and unwinding mechanism is arranged in the bounding car, and the film wound on the reel can be wound and unwound by the film winding and unwinding mechanism. When the enclosing vehicle is used for enclosing a working area, one end of the film is drawn out from the reel for a certain length so as to enclose the working area; when the working area does not need to be enclosed, the film drawn out of the reel is retracted and wound on the reel again for storage.

In order to keep the film in the enclosing operation area stable and form a stable enclosing area, a limiting mechanism is further arranged in the enclosing vehicle. The limiting mechanism comprises at least three groups of supports, and the at least three groups of supports can form a stable enclosing region.

When the operation area is encircled, the two supporting pieces are placed at proper positions of the operation area, and the clamping plates in the two supporting pieces are oppositely placed to form a first gap. The film drawn from the reel is passed through a first gap (i.e., both sides of the film are in contact with the holding plates in the two supports, respectively) so that the film can be fixedly supported at that position. Because the lower extreme of grip block is connected with the backup pad, and the both sides of backup pad are connected with the movable block, then when needs utilize support piece fixed film, can set up two movable blocks and backup pad crisscross in order to form stable support region (for example triangle-shaped support region or T shape support region), and then make the stable support of support piece and operation region's suitable position.

When the working area does not need to be encircled, the two movable blocks can be retracted to two sides of the supporting plate and are arranged in parallel with the supporting plate, then the two oppositely placed supporting pieces are retracted from the relevant positions of the working area, and the film is retracted by the film retracting mechanism. The two movable blocks are movably connected with the supporting plate, so that the supporting piece is accommodated and placed and is matched with the supporting plate to form a stable supporting area.

In a possible embodiment, the bracket further comprises a plurality of fixing elements, which are equipped to fix two clamping plates.

In the implementation process, when the two supporting pieces are matched to fix the film, the fixing pieces are used for fixing the two clamping plates, so that a stable gap can be formed between the two clamping plates, and the film in the relevant area can be stably clamped in the first gap. Moreover, the fixing members are used for fixing the two clamping plates, so that the two supporting members can be mutually matched (for example, mutually supported by the fixing members) to be stably supported at the relevant positions of the working area.

In a possible embodiment, the fixing member includes two first magnets, the two first magnets are respectively disposed on the two clamping plates, and the two first magnets are in contact with each other in an attraction manner to fix the two clamping plates.

In addition, when the diaphragm passes through the first gap, part of the film can be positioned between the two first magnets which are mutually adsorbed, so that the film is prevented from collapsing (the film has certain softness, and if the film is not fixed on the surface of the clamping plate, the film supported in the vertical direction can collapse). In addition, the film is clamped by the two first magnets, so that the film can be fixed and prevented from being damaged, and the durability of the film is improved.

In a possible embodiment, two movable blocks are optionally arranged perpendicular or parallel to the supporting plate; when the movable blocks are vertically arranged with the support plate, the movable blocks in the two support members form a second gap, and the second gap is communicated with the first gap, so that the film can simultaneously pass through the first gap and the second gap.

In the implementation process, the two movable blocks are perpendicular to the supporting plate, so that the supporting member can be more stably supported in the operation area (for example, a T-shaped supporting area is formed). And the two movable blocks form a second gap communicated with the first gap, so that the film can pass through the second gap, the lower end of the film can be contacted with the ground of the operation area, a larger gap is prevented from being formed between the film and the ground, and the sealing property of the operation area is improved.

In the implementation process, the second magnet is arranged at the movable block for forming the second gap, and the two second magnets are mutually adsorbed, so that the movable blocks in the two supporting pieces can be stably connected together. In addition, when the diaphragm passes through the second gap, part of the film can be located between the two second magnets which are mutually adsorbed, and the film is prevented from rolling (the film has certain flexibility, and if the film is not fixed on the surface of the movable block, the bottom end of the film supported in the vertical direction can be upwards rolled by the action of wind, for example, so that a gap is formed between the bottom end of the film and the bottom surface). In addition, the film is clamped by the two second magnets, so that the film can be fixed and prevented from being damaged, and the durability of the film is improved.

Because every support piece includes two movable blocks, then two movable blocks department in every support piece all is provided with the second magnet, is used for the second magnet adsorption contact with two movable blocks department in another support piece respectively.

In a possible embodiment, the two movable blocks in each support member are respectively provided with one second magnet, and when the two movable blocks are arranged in parallel with the first support plate, the projection distance between the two second magnets along the first support plate is not less than 50mm.

At above-mentioned realization in-process, when two movable blocks and first backup pad parallel arrangement, the second magnet of two movable blocks departments in same support piece is not less than 50mm along the projection interval of first backup pad, can accomodate adjacent when stacking at two support pieces, avoids the second magnet mutual adsorption in two support pieces.

When the rotating motor drives the reel to rotate clockwise (or anticlockwise), one end of the film can be drawn out for a certain length through the corresponding traction piece or the bracket; when the rotating motor drives the reel to rotate anticlockwise (or clockwise), one end of the film extraction reel can be rewound on the reel.
