Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, the every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the range of the utility model protection.
The embodiment of the utility model saving casting device：As shown in Fig. 3-Fig. 7, saving casting device includes pedestal, launching tube 7, launching tube 7
It is mounted on the base by emitting tube stent 6.Pedestal includes upper and lower spaced upper base plate, lower seat board, upper base plate, lower seat board
Between be equipped with several support columns.For understructure under the premise of meeting supporting role, weight is lighter, compact-sized.Pedestal
Rear portion is equipped with rear support leg, and there are two rear support legs and two rear support legs are arranged in "eight" shape.One in two rear support legs court downward
It is left extend, another is downward towards right extension, rear support leg is that segmentation is removable, and rear support leg includes Convenient table and the work of releasable connection
Dynamic leg.Pedestal front is equipped with front leg strut, and front leg strut has two of left and right settings.The platy structure that front leg strut is integrally formed, it is preceding
Supporting leg includes straight panel and tilt prop, and tilt prop is bent downwardly forward by the junction with straight panel, namely is tilted down forward, to match
Rear support leg is closed, pedestal is supported on ground.
Before the saving casting device of the present embodiment is opposite, innovation essentially consists in the radiation pattern of rescue rope, devises new
Transmitting barrel structure, base portion structural modification is little.The structure of launching tube part is as follows：
Transmitting barrel structure includes launching tube 7, transmitting tube stent 6, and launching tube 7 is hingedly connected to bottom by emitting tube stent 6
On seat, transmitting 6 lower part of tube stent is articulated and connected with pedestal.Pedestal is equipped with the electric pushrod of the angle of control launching tube 7, electronic
The telescopic end of push rod and transmitting tube stent 6 are hinged, and the fixing end of electric pushrod is hinged on pedestal.
Launching tube 7 includes launching tube ontology 72 and the inlet suction port 73 with the assembly of launching tube ontology 72, inlet suction port 73 are
Mounted in launching tube ontology 72 close to one end of pedestal, inlet suction port 73 is connect with launching tube ontology 72.Launching tube ontology 72 is fixed
On transmitting tube stent 6.73 other end of inlet suction port is connect with electromagnetic intake valve, and electromagnetic intake valve is by tracheae and equipped with compression
The gas cylinder of gas connects.It is fitted with transmitting bullet in launching tube 7, transmitting bullet includes that rope roll 9 for filling rescue rope and setting are being restricted
The bullet 8 of 9 outer ends of cylinder, rescue rope one end is fixed on launching tube, the other end is fixed on bullet 8, and rope roll 9 is located at launching tube 7
It is interior, emit and is formed with sealing emission cavity between bullet and launching tube 7.The barrel dliameter of launching tube ontology 72 compare before it is big, with energy
Rope roll 9 is enough installed.The inner end of rope roll 9 is equipped with rope and covers, and rope covers the cord hole equipped with wire rope handling, and rope lid, which has, to be born high pressure gas and push away
The stress surface of power.Rope lid it is not shown in the diagram go out, rope lid with rope roll 9 clamp.Rope roll 9 is made of transparent plastic, and bullet uses
Aluminium alloy is made, and bullet is slightly heavy, flight stability, to improve precision of jettisoninging.One end of bullet 8 is the plug inserted with rope roll
82, the other end has spherical structure 81.The limiting stand terrace coordinated with rope roll 9 is formed between plug 82 and spherical structure 81.
By being arranged to bullet 8 with spherical structure, rather than cone structure, transmitting bullet just in case bump against people, can reduce to it is artificial at
Injury.
Due to the initial time being ejected in transmitting bullet, rescue rope flies out therewith, and transmitting bullet needs to undertake institute
There is the weight of rescue rope, its initial velocity will certainly be reduced.In order to improve transmitting bullet initial velocity, to emit bullet mounting means into
It has gone optimization design, pin hole 71 is radially provided on 72 end of launching tube ontology, through hole 83 is radially provided on bullet 8, is being emitted
After bullet puts into launching tube ontology 72, the position of through hole 83 is corresponding with 71 position of pin hole.Transmitting bullet is fixed on transmitting by cutting off
On cylinder ontology 72, cut off across pin hole 71, through hole 83.Through hole 83 is specifically arranged on the plug 82 of bullet, in bullet 8
After being inserted on rope roll 9 and putting into launching tube 7 together, it is actually also to be interspersed on rope roll 9 to cut off.Emitting initial rank
Section, due to the presence cut off, when the gas pressure in launching tube 7 is smaller, transmitting bullet cannot be ejected, and be suppressed in launching tube 7
Pressure, pressure gradually increase, and when arriving critical value, cutting off can be cut, and transmitting bullet is popped up by high pressure gas.By building the pressure, Ke Yiti
The launch velocity degree of projectile occurred frequently, and then may be implemented to jettisoning at a distance.
Further, in order to improve the effect that builds the pressure, the structure of inlet suction port 73 is optimized, inlet suction port 73 is in
Funnel-form, inlet suction port 73 are made of bell-mouth structure of air 731 and screw thread pipeline section 732.Bell-mouth structure of air 731 and launching tube ontology 72
Connection, screw thread pipeline section 732 with electromagnetic intake valve for connecting.The structure of inlet suction port to be formed with buffering in inlet suction port 73
Air cavity.If the not structure of the optimization, the high pressure gas come out by electromagnetic intake valve is directly entered the larger launching tube of barrel dliameter
In ontology 72, pressure can be mutated, and then reduce the initial thrust to emitting bullet.
It, can be in launching tube in launching tube ontology and air inlet connecting for ease of being relatively fixed for rescue rope end and launching tube
The junction of head sets a tether bar, the snub ropes tether Gan Shangxiyou.Tether bar is positioned radially along launching tube ontology, the length of snub rope
Degree is longer than the length of launching tube ontology.When dress transmitting plays, one end of rescue rope is connect with snub rope.Certainly, in other implementations
In example, rescue rope also can be fixed directly with launching tube ontology, such as a hook is arranged in launching tube ontology, be used for tether.
When in use, rescue rope is that up to a hundred meters of rope is mounted in rope roll by cloth rope device in advance to the utility model saving casting device
In 9, rope lid is then loaded onto, rescue rope one end is fixedly connected with bullet, and the other end is connect after passing through rope lid with snub rope.Transmitting
Bullet is mounted in by cutting off in launching tube 7, after adjusting launch angle, is opened by remote control or button control solenoid valve, is first suppressed
Then pressure emits bullet and is popped up by high pressure gas；Snub rope is straightened, and then the rope in rope roll constantly discharges, and transmitting bullet carries
The weight of rope constantly reduces with the increase of cast, unlike the rope that bullet during jettisoninging of the prior art pulls is got over
Come heavier and then influences bullet flight.By verification experimental verification, the maximum of the saving casting device of the utility model jettisonings distance relatively far away from.
The utility model emits the embodiment of barrel structure, transmitting barrel structure and the launching tube knot in above-mentioned saving casting device embodiment
Structure is identical, is no longer described in detail.
