Description
Technical field
The present invention relates to mine equipment equipment technical field, specifically a kind of mine protection network throwing device.
Background technology
In mining, exposed overhanging cliff or slope are susceptible to avalanche or falling rocks after exploitation, the people to lower section
Member's property safety causes very big threat, in order to reduce or avoiding this threat, typically it is exposed it is domatic on protection network is set, prevent
Protecting wire net is generally metal material, is generally worked out using steel wire rope so that protection network has certain flexibility, is also easy to winding
And carrying, the situation that drawout is difficult under the stop of barrier can be run into when sprawling, in order to avoid such case, in paving
During exhibition protection network, generally using the gimmick jettisoninged, will protection network jettisoning and sprawl, to increase protection network accessible expansion in the air
Time, improve protection network and sprawl effect.
Common manual difficulty of jettisoninging is larger, because the protection network weight of metal material is big, it is difficult to hold, shedding effect has
Limit, can not make the abundant drawout of protection network, be subsequently to sprawl work to bring certain trouble.
The content of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of mine protection network throwing device.
The present invention solves its technical problem and employs the following technical solutions to realize：
A kind of mine protection network throwing device, including support plate, the support plate front end face is provided with front apron, the front

The support plate upper surface left and right sides is respectively provided with a spring end set, and the rear end face of the spring end set is open type
Structure, spring end set middle part is cavity structure, and the front end of spring end set is equipped with baffle ring, in the cavity of the spring end set one is equipped with
Stage clip, the front end face of the stage clip is pressed on baffle ring rear end face, and in stage clip a projectile lance is installed with, and the middle part of the projectile lance is equal
Back-up ring of the correspondence positioned at stage clip rearward end is provided with, the top of the spring end set is equipped with U-shaped support, the U-shaped support by hinge
The mode for connecing is longitudinally connected with lift pressure bar, and the top of the spring end set is equipped with the vertical post of a pair of supports, divides on the vertical post of the support
A pressure switch block is not cased with, the pressure switch block can be rotated in corresponding support on vertical post, and the pressure switch block on vertical post is supported per a pair
It is symmetrical with regard to covering the vertical section of axis along corresponding spring end, with the symmetry for ensureing to press switch block motion, press the interior of switch block
Side is radius of curvature and corresponding back-up ring outer end curvature radius identical cambered surface, so as to when pressing switch block and back-up ring to depart from,
Pressure switch block energy moment sloughs completely from back-up ring, it is to avoid back-up ring is only pressed on the area of switch block, causes to press switch block to gear
The stop of circle is unstable, or even damages the contact surface of back-up ring and pressure switch block, and the rear end of the vertical post of the support corresponds to respectively insertion drawing
In through hole on plate, support vertical post in through hole can slide anteroposterior, through hole to supporting vertical post to play position-limiting action, the pressure switch block
Bottom is kept off respectively in the dead astern of correspondence back-up ring respective side, and presses switch block to be respectively positioned on drawing plate front side, and pressure switch block plays limit to back-up ring
Position barrier effect, pressure switch block can forward promote back-up ring in the presence of drawing plate, so as to compress back-up ring front positioned at spring end set
Stage clip in cavity, is will to cast lance using stage clip to launch away basic there is provided preparing.
The rear end of the lift pressure bar extends the front side of spring end set, facilitates operated by personnel to lift pressure bar, it is to avoid operation lift pressure
Interfere with spring end set during rod, the front end for lifting pressure bar is extended directly over corresponding a pair of pressures switch block, when the front end of lift pressure bar is lifted
When, lift pressure bar rear end be pressed downward using leverage, by pressure switch block upper end be pressed downward, under pressure, pressure switch block around
Corresponding to support vertical post to rotate, from the dead astern of back-up ring, to the left and right both sides are opened for the lower end of pressure switch block, release the stop to back-up ring,
Back-up ring and projectile lance is set to project away in the presence of stage clip, so as to the protection network being connected with projectile lance be let go.
The lower weld for casting lance has the plate that draws in the net for being connected with protection network, and the lower end for drawing in the net plate is provided with drawing
Mesh, when using, protection network can bolt drawing in the net in hole, to be gone out by the related projection of projectile lance, draw in the net plate and the connection position for casting lance
Setting in the rear portion of back-up ring, it is to avoid cast lance and be cased with the part of stage clip and draw in the net plate and interfere, the plate that draws in the net is using rubber or aluminium
Alloy is made, and to reduce drawing in the net the weight of plate, prevents from casting lance when casting, and causes to cast lance due to drawing in the net the preponderance of plate
Curve of jettisoninging is moved down so that cast lance deflection, affects to cast effect, is drawn in the net the lower end of plate and is extended the front for casting lance, will be anti-
Protecting wire net is transferred to the front for casting lance to the traction force for casting lance, reduces the torque that protection network is produced to projectile lance, namely reduces
Interference effect of the weight of protection network to projectile lance projecting direction.
The internal diameter of the diameter for casting lance respectively less than correspondence baffle ring, when compressing so as to stage clip, casting lance can move forward,
The front end for casting lance is avoided to produce interference with baffle ring.
The invention has the beneficial effects as follows：The present invention is compressed on stage clip using drawing plate by lance is cast, and by pressing switch block
Stage clip is flexibly controlled to casting the position-limiting action of lance, casting lance flexibly can be compressed and be discharged, namely projectile lance can be pressed flexibly
Contracting discharges, and using shedding for lance control protection network is cast, alleviates hand labor intensity, and improve protection network sheds efficiency
With shed effect, reduce that protection network is easily interrupted during sprawling and the probability that stops.
