3. The other ends of the front vertical lifting support device 2 and the rear vertical lifting support device 1 are respectively connected to the support frame body 3.
The working process of the utility model is as follows:
one, normal support (fig. 7)
(1) After the work of the heading machine is finished, the heading machine is stopped at a proper position according to the height and the width of different roadways, and therefore the utility model discloses preparation is made for the work of the shed-erecting type temporary supporting device.
(2) According to the tunnel sky needs, will strut the flexible roof beam in side (lower floor roof beam hydro-cylinder 39 drives lower floor beam inner tube 37) of support body 3 and stretch out, lay 29U shaped steel 6 (or other kinds of shaped steel) in the shaped steel draw-in groove 31 of support body 3, through adjusting vertical upset hydro-cylinder 5 and preceding vertical lift strutting arrangement 2, the vertical lift hydro-cylinder of back vertical lift strutting arrangement 1, will strut shaped steel 6 on the support body 3 and stop in waiting to strut regional about 100mm department apart from the roof, after slightly skew adjustment about, the operation multiple unit valve (lift hydro-cylinder 34) lifts shaped steel 6 on the roof, and after exerting certain fore bearing power (the fore bearing power size is according to the mining technology requirement, the utility model discloses the device is designed to 10 ~ 30kN), be connected to main bearing shaped steel through the card cable by the workman with the supporting leg to accomplish the work of tunnel. At the moment, the section steel positioned at the top and the two supporting legs positioned on the side surfaces are connected through the clamping cables respectively, the two clamping cables are located on the same horizontal line, and the section steel and the supporting legs are symmetrically positioned on two sides of a vertical central line.
(3) After the supporting work is finished, the supporting frame body 3, the front vertical lifting supporting device 2 and the rear vertical lifting supporting device 1 are retracted, and the tunneling machine can be immediately put into work, so that the tunneling and mining of the roadway can be continuously worked.
Secondly, roadway inclined state support (fig. 8 and 9)
In the process of mining, certain coal mine fully-mechanized excavation roadways supported by shed girders in China are influenced by roadway conditions, and the phenomenon that certain sections incline occurs, so that the phenomenon that the coal mine is commonly called as 'yin-yang legs' in a coal mine as shown in figure 8 or figure 9 often occurs after miners complete shed leg installation operation. In order to avoid the phenomenon, miners often adopt one side of the shed with high legs to dig downwards until reaching the horizontal depth of the other side, and then fall down the steel main frame body, so that the labor intensity of the workers is increased, a large amount of time is wasted, the miners need to stand below an empty roof area for operation, and the safety cannot be fully guaranteed.
To this problem, the utility model discloses four group's lifting hydro-cylinders 34 (jack) adopt left front + left back or right front + right back for same group oil circuit connected mode between the upper and lower floor's roof beam that canopy type machine carried temporary support device strutted the support body, when meeting the colliery and combining the tunnel production custom and call "negative and positive leg" situation of digging in the pit, through the switching control system of hydraulic pressure oil circuit, force the shaped steel body frame artificially to slope to one side in addition, until the main frame roof beam level, solve effectively the roof that produces from this and strut the emergence that produces the slope phenomenon. At the moment, the section steel positioned at the top and the two supporting legs positioned on the side surfaces are connected through the clamping cables respectively, two clamping cable points are not on the same horizontal line, and the section steel and the supporting legs are not symmetrically positioned on two sides of a vertical central line. Thereby, the angle of shaped steel is in time adjusted according to tunnel particular case, reaches the abundant effective connection of shaped steel and supporting leg.
The result shows that the utility model relates to a colliery frame canopy type tunnel roof supporting machinery specifically is a "frame canopy type machine carries formula temporary support device-shaped steel type (29U shaped steel, I-steel, beam channel-section steel or other)", and this equipment makes tunnel roof manual support work in the pit change into mechanized operation control, solves the waste in time that entry driving machine and temporary support device components of a whole that can function independently work caused, dangerous height to and workman's intensity of labour big scheduling problem. The utility model discloses frame canopy type machine carries formula temporary support device installs above entry driving machine cutting units through locating pin axle, form the integration with the entry driving machine and be connected, this "support device" has the shrink and extends, the vertical lift, roof support body secondary is exerted pressure, control the side deflection lift and look single roof beam or the double-frame roof beam operation selected mode of tunnel roof condition randomness, especially this "support device support body" adopts spring bow plate contact mode with the atress mode of tunnel roof, make "support device" the stress state obtain the radical change, thereby really realize the needs of internal colliery to adopting shaped steel to strut the operation production as frame canopy type.
