Specific embodiment
It is specific below in conjunction with the utility model to keep the purpose of this utility model, technical solution and advantage clearer
Technical solutions of the utility model are clearly and completely described in embodiment and corresponding attached drawing.Obviously, described embodiment
It is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without making creative work, belongs to the utility model
The range of protection.
Below in conjunction with attached drawing, technical solution provided by the embodiment of the utility model is described in detail.
When the construction of progress coal mining or underground installation, tunnel piercing is carried out in underground using development machine.Development machine
Front end (using development machine advance direction as front end, on the basis of attached direction shown in FIG. 1, left side is front end) be provided with cutting
Mechanism, cutting mechanism include main body X1 and the cutterhead X2 positioned at the front end main body X1.Cutterhead X2 plays the role of cutting and broken rock,
And cutterhead X2 is rotatably arranged in the front end of main body X1, when stopping driving, cutterhead X2 can slope down to landing shape
State.
As shown in the picture, the utility model embodiment provide a kind of tunnel piercing protective device include: fixed plate 1, it is sliding
Move part 2, frame body 3 and flip piece 4.Fixed plate 1 is fixed on the main body X1 of cutting mechanism for heading machine；Sliding component 2 can axially slide
Ground is arranged in fixed plate 1.The front end of frame body 3 is connect with the front end of sliding component 2 by shaft 5, and flip piece 4 is connected to frame body 3
Between sliding component 2, for driving frame body 3 to open or retraction, frame body 3 offsets when opening with driving face.
The working principle of tunnel piercing protective device provided by the embodiment of the utility model is illustrated below:
When development machine normally tunnels, frame body 3, which is attached on sliding component 2, keeps retracted state, and sliding component 2 is located in fixed plate 1,
Fixed plate 1 is located on the main body X1 of cutting mechanism, does not impact to the cutting broken rock of cutterhead X2, does not influence excavation operation
It carries out.
When excavation operation stops carrying out supporting operation, sliding component 2 slides onto forward the front end of sliding component 2 in fixed plate 1
The pre-determined distance of front end one beyond cutterhead X2 afterwards turns over the overturning of 4 action drives frame body 3 of part, is formed between sliding component 2
Angle, frame body 3 are opened and are offseted with driving face, carry out supporting to driving face.The support work for having excavated tunnel is complete
Cheng Hou, frame body 3 bounce back, and sliding component 2 is moved to the top of the main body X1 of cutting mechanism, at this point it is possible to carry out the pick of next stage
Into work.Wherein, pre-determined distance can be set according to the actual situation, such as can be 0.2m, 0.3m, 0.5m etc..
As it can be seen that tunnel piercing protective device provided by the embodiment of the utility model, through sliding component 2 in fixed plate 1
Translation, enables frame body 3 not interfere to headwork in the state of driving, can be moved to default position after driving stops
It sets and is opened under the action of flip piece 4 and supporting is carried out to driving face, avoid driving face from collapsing and fall rock, avoid
Manually-operated safety accident, is greatly improved safety.
Wherein, cutterhead X2 does not cause the movement of sliding component 2 when carrying out driving face support to open frame body 3
Interference first can downwardly turn over cutterhead X2 to landing state after driving stops, and the highest point of cutterhead X2 is located at this time
The bottom surface of sliding component 2 hereinafter, sliding component easy to remove 2 to supporting position.
In the utility model embodiment, sliding component 2 is driven by telescopic oil cylinder, so set, structure is simple, it can be more
Easily operate the movement of sliding component 2.
Wherein, the cylinder body of telescopic oil cylinder can be fixed in fixed plate 1, and piston rod is connect with the one side of sliding component 2.It stretches
When contracting cylinder action, the translation of piston rod drives sliding component 2 to translate.
In order to glance off sliding component 2 not in translation motion, the upper side of fixed plate 1 is provided with along axial cunning
Road, sliding component 2 slide in slideway.Sliding component 2 is limited by the way that slideway is arranged, improves the stability and safety of device
Property.
In the utility model embodiment, flip piece 4 is for driving frame body 3 to open or bounce back, as an example, flip piece
4 be the hydraulic cylinder being connected between frame body 3 and sliding component 2；The cylinder body of hydraulic cylinder is fixed on sliding component 2, hydraulic cylinder
Piston rod connect with frame body 3.
Since the front end of frame body 3 and the front end of sliding component 2 are connected by shaft 5, when hydraulic cylinder acts, piston rod elongation
Perhaps shorten and frame body 3 is driven to open or bounce back relative to sliding component 2.
It is understood that the length flexible by the piston rod of control hydraulic cylinder, the angle that can be opened to frame body 3
It is controlled.
Wherein, the quantity of hydraulic cylinder can be two, and the cylinder body of two hydraulic cylinders can be separately fixed at sliding component 2
Symmetrical two sidewalls on, the piston rod of two hydraulic cylinders is connected to the different location on the downside of frame body 3, two
Hydraulic cylinder is symmetrical, uniform force when frame body 3 being made to stretch, and acts more stable.
Further, axial position is provided with two reinforcements, the piston of two hydraulic cylinders on the downside of frame body 3
Bar is connected on two reinforcements, so set, when the intensity of frame body 3 can be made higher and acting hydraulic cylinder
The deformation of frame body 3 is smaller.
Illustratively, the maximum opening angle of frame body 3 is greater than or equal to 90 degree, and frame body 3 is enable to have biggish movable sky
Between, angle appropriate can be opened according to the structure and Adjusting Shape frame body 3 of driving face, to the heading driver under different operating conditions
Make face and carry out supporting, expands the scope of application.
Frame body 3 and driving face carry out support work when offseting, and avoid driving face from collapsing or fall rock, for frame body
3 structure, is illustrated below:
As an example, frame body 3 can be plate structure, when the frame body 3 of plate structure offsets with driving face from
To good support effect, supporting effect is preferable.
As another example, frame body 3 can be mesh-plate structure.Mesh-plate structure can play support effect to driving face
Fruit, and material can be saved, mitigate the weight of frame body 3.
It is understood that the mesh size of mesh-plate structure frame body 3 can be by geological state and the coal of driving face
The partial size of block, sillar etc. determines, as long as can reach support purpose.
Tunnel piercing protective device provided by the embodiment of the utility model further includes control module, control module and flexible oil
Cylinder is connected with hydraulic cylinder, for controlling telescopic oil cylinder and hydraulic cylinder movement.
Hydraulic cylinder and telescopic oil cylinder are controlled by control module, and then control the tunnel piercing protective device
Working condition is more convenient.And the operating side of control module can be located at by the operator seat of development machine, be convenient for operator
It is operated, improves safety and convenience.Further, hydraulic oil more easily can accurately be controlled by control module
The actuating length of cylinder controls the flip angle of frame body 3.
