In addition, establish two round stationary magazine creels of symmetry before the bracket base and rotate gudgeon, wouldn't install when rotating gudgeon and prevent cash, establish two symmetrical earholes on the conveyer, this device of installation capable of reversing with door for installing; Rotate earhole relative dimensions on gudgeon, the conveyer before jack stroke, cross head length and the bracket base, must satisfy the requirement that coal-winning machine cuts dark, unit advance and adjacent two bases height 250mm, and suitably leave She's amount.The conveyer shoe is installed (drawing) power that pushes away of quantity and jack, decide according to the weight that uses seam inclination size and conveyer (joint), can 3～5 sets up one group, also can every all establishes, and guarantees the adjusting of conveyer and anti-skidding.
The utility model is mainly used in large tilt angle compound mining work plane conveyer adjusting and anti-skidding, and its advantage is:
1, this is a kind of hard connecting mode, by regulating the desired position of conveyer by (drawing) power that pushes away of jack, locking with jack pushes away (drawing) power and prevents that conveyer from gliding then, regulates and an anti-skidding difficult problem thereby fundamentally solved large tilt angle compound mining work plane conveyer.
2, the stroke of jack fully satisfies conveyer and moves the variation requirement, and suitably leave She ground (＞50mm), move at conveyer and to change under the operating mode, this device also can be guaranteed conveyer adjusting and antiskid function.
3, install (drawing) power that pushes away of quantity and jack, determine, can 3～5 set up one group, also can every all establish according to the weight that uses seam inclination size and conveyer: installation up, the very heavy pushing tow of locking chamber, thrust is big, works very well; Install down, then can only draw the chamber by the locking jack, pulling force is little, and effect is not good enough, preferably adopts less.
4, it is lower to install the position, has got rid of various interference, prevents from simultaneously to waft on the ramp plate before the conveyer and leaks bastard coal, and this is that conveyer is regulated and anti-skidding preferred plan; Analyze possible adjusting of other conveyer and anti-skidding mode, more because of interference and pros and cons factor, reliability is limited.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated:
By Fig. 1-shown in Figure 2, common fully-mechanized mining working is made up of some supports 1, conveyer 2 and coal-winning machine 3; This shoe 4 is suitable for the large tilt angle compound mining work planes, support 1 with on 2 of adjacent frame front conveyors add this shoe 4, be benchmark with support 1, solve the anti-skidding problem of conveyers 2 by shoe 4, coal-winning machine 3 rides over reciprocal cut coal on the conveyer.
By shown in Figure 3, this shoe 4 is made up of cross head 5, jack 6, rotation gudgeon 7 and bearing pin 8.Establish before the base of support 1 (this) and rotate gudgeon 7, by jack 6, cross head 5 and bearing pin 8 link to each other (being connected firmly) with otic placode on the last adjacent frame front conveyor 2, by jack 6 control conveyers 2 positions, the adjusting of realization conveyer 2 and anti-skidding.The preceding duct that rotation gudgeon 7 is installed of continuous hole of otic placode on the conveyer 2 and support 1 base all is symmetrical, a commutation installation when being convenient to the work plane tuning.The duct of rotating gudgeon 7 wouldn't be installed, with door 9 anti-bastard coals before support 1 base.L1 is a center to center distance between two of support 1, L2 installs the duct spacing of rotating gudgeon 7 before the bracket base, L7 is conveyer 2 upper ear plate pitch-rows, L3 is the distance of moving of conveyer 2, L4, L6 are oblique distance (length of jack 6 adds cross head 5 pitch-row L5) before and after conveyer shoe 4 is passed, jack 6 strokes must satisfy conveyer and move the variation requirement and suitably leave She ground (more than ± 50mm), be that L4=jack 6 longest dimensions+pitch-row L5 (cross head 5 pitch-rows) is necessary＞50mm, L6=jack 6 the shortest size+L5 (cross head 5 pitch-rows) are necessary＜50mm.
