Description
The utility model belongs to a kind of mining suspension device, is fit to the coal mining work plane and uses.
At present, the colliery high-grade common coal mining face adopts articulated roof beam and individual prop supporting more, propelling along with coal-face, need constantly back row's articulated roof beam and individual prop to be removed, move and be installed to the front row, move back timber and individual prop labour intensity is big, inefficiency, dangerous, easily lose post.
The purpose of this utility model is a kind of whole beam column passing formula top protecting support that need not tear beam open and tear post open of design, utilizes a kind of special-purpose support moving device to finish the displacement task of support by manually pushing away frame.
The whole beam column that the utility model proposes pass the formula top protecting support by about two back timbers and support the left and right sides support that monomer column is formed, support moving device and metal backing formation.Every back timber can be supported by many individual props, links together by the hanging column device between back timber and the single-column, and back timber is not held and is connected with a diagonal brace friction prop, is used to keep off cash.The hanging column device is welded on the back timber lower end, and the hanging column device is made up of column sleeve, cushion pad and two semicircle pins and handle thereof, and two semicircle pins and handle thereof are installed on the column sleeve, relies on minimum after two semicircle pins rotate or maximum spacing to block or unclamps individual prop.To protect top area in order enlarging, to avoid the breaking roof rock to drop, on back timber, set up metal backing, to replace plank lagging.The metal backing two ends have two rectangular notches, can ride on two back timbers by direct at a certain distance frame, metal backing plays connection frame and the effect of protecting the top simultaneously behind the individual prop stretching, and the central authorities of metal backing also have a pin-and-hole in addition, are used for fixing support moving device.Support moving device is made of longitudinal slide and idler pulley.Longitudinal slide is made up of slide rail and slide block.The slide block lower end has two pin-and-holes that tapering is opposite, so that from both direction idler pulley can both be installed.Idler pulley is made of axle center and rotatable roll sleeve, and an end of idler pulley has a circle plate washer, and the other end is a link, one pin-and-hole is arranged on the termination, the link of idler pulley inserts in the pin-and-hole of slide block lower end, is fixed on the slide block with pin, and idler pulley can move forward and backward along slide rail by slide block.The upper end of slide block is an articulated end, and support moving device is fixed on the metal backing by the articulated end on the slide block, pin-and-hole and pin on the metal backing.
On the support two support moving devices need be installed on two metal backings in front and back when moving frame, left and right sides support moves respectively.When moving left socle two idler pulleies on two support moving devices are installed in the Zuo Liang lower end, make right support prop up top board earlier, the release liquid of the individual prop on the left socle, left socle is slowly dropped on the idler pulley of support moving device, inner spring of individual prop is pulled away from base plate and is suspended on the back timber, by manually left socle integral body being passed forward, live the individual prop of back until the idler pulley shelves, this moment, left socle can continue to move forward along slide rail together with idler pulley by slide block, had guaranteed that support can move forward a complete post distance.Make left socle prop up top board when moving right support, two idler pulleies are installed to the You Liang lower end, get final product with quadrat method by above-mentioned.After support displacement in the left and right sides finished, back timber did not hold the metal backing of taking off can be placed to the back timber front end when be shifted next time.
The advantage that the whole beam column that the utility model proposes is passed the formula overhead guard is need not repeat to tear open, remove, and back timber and individual prop are installed, have been alleviated labour intensity greatly, improved operating efficiency, adopt frame striding type metal backing to protect the top simultaneously, reusability height, intensity are big, a large amount of timber have been saved, low, simple in structure, the suitable China's national situation of this support cost has broad prospect of application.

The utility model is described further with embodiment below in conjunction with accompanying drawing:
The whole beam column that the utility model proposes pass the formula top protecting support by about two back timbers 2 and support the left and right sides support that individual prop 1 is formed, support moving device and metal backing formation, shown in Figure 2 by Fig. 1.Every back timber is supported by three individual props, back timber tail end diagonal brace a shelves cash friction prop 23, link together by the hanging column device between back timber and the individual prop, hanging column device 3 is made up of column sleeve 19, cushion pad 20 and two semicircle pins 21 and handle 22 thereof, the hanging column device is welded on the back timber lower end, the column cap of individual prop, is utilized minimum after two semicircle pins rotate or maximum spacing to block or unclamps individual prop in column sleeve 19 by two semicircle pin 21 clips.As shown in Figure 7.Frame is being ridden 6 metal backings above the back timber of the left and right sides, and metal backing central authorities have a pin-and-hole, as shown in Figure 6, is used for fixing support moving device.Support moving device is made of longitudinal slide and idler pulley 9, as shown in Figure 3.Longitudinal slide is made up of slide rail 12 and slide block 13.The slide block lower end has two pin-and-holes that tapering is opposite, as Fig. 4, shown in Figure 5, can idler pulley be installed from both direction.Idler pulley is made of axle center and rotatable roll sleeve, and an end of idler pulley has a circle plate washer 16, and the other end is a link, one pin-and-hole 11 is arranged on the termination, the link of idler pulley inserts a pin-and-hole 15 of slide block lower end, is fixed on the slide block 13 with pin, and idler pulley can move forward and backward along slide rail by slide block.The upper end of slide block is an articulated end 14, and support moving device is by the articulated end on the slide block 14, and pin-and-hole 18 and pin 10 on the metal backing are fixed on the metal backing.
Need to install two support moving devices when moving frame on the support, left and right sides support moves respectively.Two idler pulleies with two support moving devices when moving left socle are installed in the Zuo Liang lower end, make right support prop up top board earlier, the release liquid of the individual prop on the left socle, left socle is slowly dropped on the idler pulley of support moving device, inner spring of individual prop is pulled away from base plate, or resets by hydraulic pressure and to be suspended on the back timber, by manually left socle integral body being passed forward, until the individual prop that the idler pulley shelves are lived the back, this moment, left socle can be by moving forward a complete post distance together with idler pulley.Make left socle prop up top board when moving right support, two idler pulleies are installed to the You Liang lower end, move frame and operate same as described above.After support displacement in the left and right sides finished, back timber did not hold the metal backing that takes off can be placed to the back timber front end when be shifted next time.
