The front end of the bottom of 1 is connected, and the middle part of arc is protruded to the bottom of the direction of advance of advanced hydraulic support 4.
Guide plate 3 includes the first fixed plate 301 and is connected to the cutting part 302 bottom the first fixed plate 301, at fixing groove
The both sides of the length direction of 5 are respectively arranged with the second fixed plate 101, are provided with pin hole 102 in the second fixed plate 101,
Being provided with fixing hole 303 in first fixed plate 301, fixing hole 303 is with pin hole 102 by latch by the first fixed plate 301 admittedly
It is scheduled in the second fixed plate 101；Cutting part 302 is cutter, and the bottom of the knife back and the first fixed plate 301 is connected, the rear end of cutter
The front end of bottom and the knife back be connected to form the blade of arc, mainly for incipient stage guide plate 3 can be pressed onto roadway floor with
Under, play guide effect.
Roadway floor is hard base plate, allows that uniaxial compressive strength is more than 42.00MPa, and described fixing hole 303 is cut with described
Cut the distance between the lowermost end in portion 302 be H+100mm, H be advance timbering base thickness, unit is mm.Cut in view of base plate
The resistance that cuts and the demand relation between provided lateral pressure is provided, through many experiments, for backplane type be
In the case of hard base plate, the size of H+100mm is most suitable, and other sizes cannot meet demand.
A length of 360mm in horizontal direction before and after anti-drilling bottom baffle 2, the height in upper and lower vertical direction is 400mm.
It is below preferred version:
The upper and lower of the rear end of bearing block 1 is connected to upper mounted plate 6 and bottom plate 7, advanced hydraulic support 4
Base front end use fixing band 8 be fixed between upper mounted plate 6 and bottom plate 7, a length of 360mm of upper mounted plate 6,
Thickness is 7mm.
The cross section of described first fixed plate 301 on top 2/3rds be shaped as rectangle, the institute of bottom 1/3rd
State the first fixed plate 301 cross section be shaped as trapezoidal, the length of the front end of described first fixed plate 301 is less than the length of rear end
Degree.This is mainly designed to reduce resistance during passage at advanced hydraulic support 4.
A length of 430mm before and after bearing block 1, width is 450mm, the height of height and the base of advanced hydraulic support 4
Unanimously, a length of 300mm before and after fixing groove 5, width be the distance between 15mm, and the front end of bearing block 1 be 40mm, load-bearing

Plate 7 is welded and fixed；Fixing band 8 is the long iron block of steel wire sheet or molding.
A length of 290mm before and after guide plate 3, width the widest part is 13mm, and the narrowest place is 3～4mm, the thinnest the most disconnected
Splitting, the thickest resistance is too big, DeGrain；Ensure that guide plate 3 can be inserted in fixing groove 5 the most easily, and the gap of 2mm
Ensure that guide plate 3 will not be in loading process, because gap deviate from rectilinear movement state；It is highly 600mm；Fixing hole 303
The distance of front end of centre distance the first fixed plate 301 be 150mm, the distance of rear end is 140mm, the diameter of fixing hole 303
For 25mm；A diameter of 12mm of pin hole 102, a diameter of 10mm of latch, it is ensured that latch can be inserted into pin hole 102 He smoothly
In fixing hole 303, and the diameter of 10mm ensure that the strength demand of latch.
The Assurance of Size of present invention latch can pass hole, and during moving frame, guide plate 3 can be in the effect of resistance
Under side shifting backward, guide plate 3 can do a small size rotation counterclockwise with the contact point of right side and fixing groove 5 end as the center of circle
Turning, probably bring the rotation of hole 8mm, therefore, a diameter of 25mm of fixing hole 303 ensure that guide plate 3 bottom and fixing groove
During 303 right contact, latch and hole surrounding all have the space of at least 2mm, and latch will not be the most tangential by fixing hole 303
Power, and the diameter of 10mm also ensure that hole to latch shearing stress upwards to latch intensity considerable influence, it is ensured that the section of device
Learn reliable.
Anti-drilling bottom baffle 2 is exactly mainly a curved plane shuttering panels, and Main Function is to elapse at advanced hydraulic support 4
During, utilize the shaped form of self to design, it is ensured that whole device and advanced hydraulic support 4 base all receive one upwards point
Power, it is to avoid before much under weak base plate, bores the situation at the end and occurs, enter one simultaneously during advanced hydraulic support 4 passage
The generation of the dangerous situations such as step has been evaded because boring the sideslip of tail band, rollover, guide plate 3 itself more can guarantee that device is with advanced
Hydraulic support 4 is walked on one accurately programme path, safe and reliable, practical.
All sizes of the present invention are preferred version, and the effect brought is more preferable, but not necessarily.
The using method of the support directional movement structure improved based on support base plate of the present invention, comprises the steps:
(A) before needs move frame, it is directed to plate 3, bearing block 1 and anti-drilling bottom baffle 2 transport other to advanced hydraulic support 4
Limit, excavates slightly the ditch of a deep 20mm at advanced hydraulic support 4 pan frontward end, by the bottom plate 7 of bearing block 1 along in advance
It is gradually inserted below the base of hydraulic support 4, inserts at least 500mm, when resistance pushes away to enter more greatly, stop manual work,
Personnel, away from support, move frame by advanced hydraulic support 4, progressively make bearing block 1 arrive the front end of advanced hydraulic support 4 base；
Stop moving frame, all around beat bearing block 1 with iron hammer so that it is front and back align with about base so that it is parallel with base front and back
Adjacent；
(B) rotate to upper mounted plate 6, above bearing block 1, be connected with bottom plate 7 by upper mounted plate 6 by fixing band 8
And be tightened；
(C) putting into guide plate 3, the edge of a knife direction of the bottom of guide plate 3, in moving direction front, is directed to plate 3 with iron hammer
Pound the position of fixing hole 303 correspondence, insert latch, Fixed latches, connect with guide plate 3 with the left and right sides on rear side of fixing groove 5
The place touched, fills in a small amount of burlap or Corchorus olitorius L., reduces the hard contact between iron block, reduces the space of 2mm to leading as far as possible
The steering error caused to plate 3；
(D) turn to when needs or during adjustment direction, stop moving frame, manually beat pressure block 1 side with iron hammer, make pressure-bearing
Block 1 forms little crack with the pan frontward end of advanced hydraulic support 4, fills in an appropriate number of small size standard iron block 9, uses one piece
The anglec of rotation of small size standard iron block 9 is 2 °, lays particular number as required；When quantity is more than 3 pieces, use large size standard
Iron block 10, the angle of formation is 6 °.
As shown in Figure 4 and Figure 5, length and width and the height of small size standard iron block 9 is respectively 150mm, 15mm and 150mm, large size mark
Quasi-iron block 10 is trapezoidal, a length of 300mm, a width of 31mm of upper end, a width of 47mm of lower end, a height of 150mm.Large size standard ferrum
Block 10 has certain deformation, to meet the demand of wedge shape space.
Embodiment described above is only to be described the preferred embodiment of the present invention, the not model to the present invention
Enclose and be defined, on the premise of designing spirit without departing from the present invention, the those of ordinary skill in the art technical side to the present invention
Various deformation that case is made and improvement, all should fall in the protection domain that claims of the present invention determines.
