1. a band alarm and for the mounting assembly of LED display (26), comprise the track girder (12) with upper and lower two rail slots (120) being fixed on the upper also cantilever of building (1201) and stretching out, the bottom roller (13) that can roll in described two rail slots (120) respectively and upper roller (14) and be connected to LED display installation connecting element (261) and the drive cassette (27) of both described bottom roller (13) and upper roller (14) both sides, described drive cassette (27) comprises supporting frame (9), be provided with in support frame as described above body (9) can in the vertical direction slide in opposition and from slide two roller compression skewbacks:

  • bottom roller compress skewback (4) and upper roller compression skewback (5), described bottom roller compresses skewback (4) and upper roller compresses in skewback (5) lower rotary shaft (6) and upper rotating shaft (7) that can be provided with substantially horizontal extension respectively rotationally, to be connected with described bottom roller (13) and upper roller (14) respectively, wherein, described LED display installation connecting element (261) comprise with gliding groove and upper hopper chute connection housing (262) and be slidably matched with described gliding groove and upper hopper chute respectively thus lower L-type link (66) and the upper L-type link (77) of described LED display (26) can be carried, wherein, the one that the vertical leg of the template in the two L-type structure of described lower L-type link (66) and upper L-type link (77) is corresponding with described gliding groove and upper hopper chute coordinates, the horizontal leg of the spindle-type in the L-type structure one corresponding with described bottom roller (13) and upper roller (14) in the circumferential rotatably and fixedly connect in the axial direction, wherein, lower elastic element (41) is fixedly connected with separately respectively and upper elastic element (51) separates for described bottom roller (13) and upper roller (14) top being pressed between described lower L-type link (66) and upper L-type link (77), described bottom roller compress side away from each other that skewback (4) and upper roller compress skewback (5) be respectively arranged with skewback inclined-plane to be engaged by the voussoir inclined-plane on the voussoir bump (81) at the upper-lower position place with sliding wedge parts (8) described sliding wedge portion (8) at the square upward sliding away from described track girder (12) time described bottom roller compressed skewback (4) and upper roller and compresses skewback (5) and push up and be pressed against closely, thus described bottom roller (13) and upper roller (14) are entered in described rail slot (120) and is close to described track girder (12), the upper rotating shaft (7) of described drive cassette (27) is connected with movable motor (11) power being positioned at described upper rotating shaft (7) upside by belt (71), thus, when described bottom roller (13) and upper roller (14) to enter in described rail slot (120) and are close to described track girder (12), described belt (71) is tensioned, the slip joint portion (83) that described sliding wedge portion (8) comprises described voussoir bump (81), be fixedly connected with described voussoir bump (81) to contact and to be fixedly installed on screw thread pushing part (82) between described slip joint portion (83) with the inner slide of support frame as described above body (9), the middle part of described screw thread pushing part (82) be provided with promote screw with lead-screw (15) screw-thread fit driven by clamping motor (141), the inner side of support frame as described above body (9) is positioned at described bottom roller and compresses and be provided with feeler (67) between skewback (4) and upper roller compression skewback (5) and be electrically connected with described clamping motor (141), described feeler (67) in order to compress when described bottom roller skewback (4) and upper roller compression skewback (5) in the vertical direction slide in opposition and contact with described feeler (67) time, then described feeler (67) transmission of signal control described clamping motor (141) and shut down, now described bottom roller (13) and upper roller (14) to enter in described rail slot (120) and are close to described track girder (12), the top of support frame as described above body (9) is also provided with alarm (68) and is electrically connected with described feeler (67) in order to control to control while described clamping motor (141) shuts down described alarm (68) to work alarm of sounding when described feeler (67) transmission of signal, point out described bottom roller (13) and upper roller (14) to enter in described rail slot (120) intuitively by alarm sound and be close to described track girder (12), thus prevent described clamping motor (141) from operating always and make described bottom roller compress skewback (4) to compress skewback (5) with upper roller and collide and damage, wherein, the end that described lower rotary shaft (6) and upper rotating shaft (7) are stretched out away from described track girder (12) is provided with lock shaft joining portion (70) in order to engage with the sticking department (701) be fixedly installed on support frame as described above body (9) when described lower rotary shaft (6) and upper rotating shaft (7) top are pressed against and closely put in place by described sliding wedge parts (8) thus to realize the rotational lock to described lower rotary shaft (6) and upper rotating shaft (7).
