Abstract
The utility model relates to a push and press type clamping device, which belongs to the field of a clamping device used for connecting a fixed machine. The clamping device is assembled by clamping arms, a push seat, a push head and a connecting rod. The utility model has the advantages of simple structure, easy manufacture, safe, stable and reliable operation, labor saving, low labor intensity, short time for replacement and maintenance, and high work efficiency.
Description
The utility model relates to a kind of roof pressure and tightens up the formula anchor clamps, belongs to the anchor clamps field that is connected and fixed mechanical usefulness.The current chain type transportation device that is used to transport transmission, its sprocket wheel, sprocket shaft, axle sleeve, carrier bar are all easy to wear, need frequent repair and replacement.This chain equipment of past repair and replacement in the past is to carry out with artificial chain block, operates the chain block shakiness like this, and work difficulty is big, and labour intensity is big, and the repair and replacement time is long, and the accident that cucurbit chain or steel cable are broken also easily takes place.
The purpose of this utility model provides a kind of new anchor clamps, and promptly roof pressure tightens up the formula anchor clamps.This clamp structure is simple to be made easily, operate firmly safe and reliablely, flexible and convenient to use, reduces labor intensity, and the shortening repair and replacement time, increases work efficiency.
The utility model is realized by following technology contents for achieving the above object.These anchor clamps are to be assembled by jig arm, footstock, top, connecting rod, bearing pin.Described jig arm is two curved tongs (1) that collude shape of an arm end with holes, and the steel plate bar that is complementary in its afterbody two tong therebetween and they are weldingly fixed on together constitutes; Footstock is that its other end of end connecting rod with holes (2) is burn-on with plectane (3) formation of semi-convex ring; The top is that its other end of end connecting rod with holes (4) is burn-on with plectane (5) formation of semi-convex ring; Connecting rod (6) two ends are porose; With footstock and the connecting rod (2) of top and tong (1) centre of two jig arm that assemble of the corresponding respectively insertion of connecting rod (4) that assembles, use bearing pin (7) that cooresponding connecting rod and tong are fixed respectively, form footstock jig arm and top jig arm, again the two ends of connecting rod (6) are inserted the footstock jig arm respectively and with bearing pin (7) connecting rod (6) two ends are fixed together with corresponding tong respectively, so far constitute roof pressure and tighten up the formula anchor clamps with the tong (1) of top jig arm is middle.The working process of these anchor clamps is: the associated components of repair and replacement is placed between two jig arm, again jack is placed between footstock and the top, hand jack produces pressure and makes footstock and come directly towards outer moving, thereby corresponding two jig arm tail ends are expanded outwardly out, because the effect of connecting rod between two jig arm, two jig arm arcs collude the shape head and tighten up in same plane the repair and replacement part is clamped.
The utility model has the advantages that: the easy making simple in structure of this folder meal, operate firmly safe and reliablely, flexible and convenient to use, the saving manpower, save time, increase work efficiency.
Fig. 1 tightens up the front elevation of formula anchor clamps for roof pressure.
Accompanying drawings embodiment.The making that roof pressure tightens up the formula anchor clamps is: at first make four tongs (1) tongs (1) head with steel plate by designing requirement and make arc and collude shape and open arm hole and uropore at arm and afterbody appropriate location, the steel plate bar that is complementary in per two tongs (1) afterbody therebetween one is also made two jig arm with two tong solder togethers and is made connecting rod (2) with steel plate, plectane (3), connecting rod (4), plectane (5), the afterbody perforate of connecting rod (2) and connecting rod (4), the thin first steel of outer edge weldering half-turn of plectane (3) and plectane (5) is again with connecting rod (2) and plectane (3), connecting rod (4) and plectane (5) are welded together to form footstock and top; The afterbody of the connecting rod (2) of footstock and top and connecting rod (4) is inserted respectively in the middle of tong (1) afterbody of two jig arm, fixing tight with cooresponding tong with bearing pin (7) connecting rod (2) and connecting rod (4), form the footstock jig arm and come directly towards jig arm; Insert respectively in the middle of tong (1) arm of footstock jig arm and chuck jig arm make two porose connecting rod (6) two ends by steel plate at last, connecting rod (6) two ends and corresponding tong are fixed together, so far constitute roof pressure and tighten up the formula anchor clamps with bearing pin (7).
Claims (1)
1, a kind of roof pressure tightens up the formula anchor clamps, it is characterized in that: these anchor clamps are made of jig arm, footstock, top, connecting rod, bearing pin assembling, described jig arm is that two build portions are that arc colludes shape, arm, the porose tong (1) of afterbody, and folder steel plate bar solder together constitutes between its afterbody; Footstock is that its other end of tail end connecting rod with holes (2) is burn-on with plectane (3) formation of semi-convex ring; The top is that its other end of tail end connecting rod with holes (4) is burn-on with plectane (5) formation of semi-convex ring; Connecting rod (6) two ends are porose; Connecting rod of footstock and top (2) and connecting rod (4) insert respectively between cooresponding tong (1) afterbody, fixing tight by bearing pin (7), form footstock jig arm and top jig arm, insert respectively between tong (1) arm of footstock jig arm and top jig arm at the two ends of connecting rod at last that two ends are with holes (6), and with bearing pin (7) connecting rod (6) two ends are fixed together with corresponding tong, constitute roof pressure and tighten up the formula anchor clamps.
