Abstract
The utility model belongs to a lifting appliance special for lifting a worm gear screw lifter of a vertical rolling mill during overhauling, and in particular relates to a balance rotatable lifting appliance. A main lifting lug and an auxiliary lifting lug are respectively arranged on the top surfaces of the middle and the tail of a square pipe-shaped beam; a rotatable hoop is arranged on the end face of the head of the beam; and a position-adjustable counterweight is arranged on the other side of the beam. By the lifting appliance, the worm gear screw lifter can be vertically lifted to a mounting position from the side directly, can be conveniently clamped and is automatically vertical downward in the ascending process, labor intensity is reduced, maintenance efficiency is improved, and the operation risk is reduced.
Description
Technical field
The utility model belongs to the special hanger of maintenance lifting vertical mill Screw of Worm Gear elevator, the rotatable suspender of particularly a kind of balance-type type.
Background technology
At present, because vertical direction has obstacle, can only get into from the side during the lifting of maintenance vertical mill Screw of Worm Gear elevator, driving can't directly winch to the installation site with it, needs to lean on manpower that it is pushed the installation site, and very effort and efficient are lower, and dangerous.
Summary of the invention
The purpose of the utility model is to provide a kind of balance-type type rotatable suspender; Not only can directly from the side the Screw of Worm Gear elevator vertically be winched to the installation site; And can tighten the Screw of Worm Gear elevator easily and in uphill process automatically vertically downward; Reduce labour intensity, improve maintenance efficiency, reduce operating risk.
The purpose of the utility model is achieved in that the rotatable suspender of a kind of balance-type type; In the middle part of the crossbeam of square tube type and on the end face of afterbody main hanger and secondary hanger are being set respectively; Rotatable clip is being set on the end face of crossbeam head, the counterweight of adjustable position is being set at the opposite side of crossbeam.
The crossbeam top of the utility model is main hanger by midway location, and one of arm is a movable balance weight, and one is clip, can get into the space that there is obstacle the top from the side; Can rotate freely at described rotatable clip, make the Screw of Worm Gear elevator automatically straight down in the lifting process; In described screw mechanism, shake optional position, centre that handle can mobile counterweight to crossbeam, and counterweight can do certain rotation, prevent that leading screw receives diametral load when crossbeam tilts, cause the leading screw bending to an end.
Beneficial effect is: can make Screw of Worm Gear elevator freedom in 1, the lifting process straight down; 2, can directly from the side the Screw of Worm Gear elevator be winched to the installation site; 3, shake handle adjusting balance position and can lift by crane the Screw of Worm Gear elevator of different model; 4, at crossbeam counterweight end secondary suspension hook is arranged, the unexpected rollover that causes in the time of can preventing crossbeam two ends overbalance.The utility model has been realized directly from the side the Screw of Worm Gear elevator vertically being winched to the installation site; And tighten the Screw of Worm Gear elevator easily and in uphill process automatically vertically downward; Reduce labour intensity, improved maintenance efficiency, reduced operating risk.
Description of drawings
To combine accompanying drawing that the utility model is done further to describe below,
Fig. 1 is the perspective view of the utility model;
Fig. 2 is A-A sectional structure scheme drawing of Fig. 1.
The specific embodiment
The rotatable suspender of a kind of balance-type type; Like Fig. 1, shown in Figure 2; Main hanger 3 and secondary hanger 4 are being set respectively on the end face of crossbeam 2 middle parts of square tube type and afterbody, rotatable clip is being set on the end face of crossbeam 2 heads, the counterweight 6 of adjustable position is being set at the opposite side of crossbeam 2.The structure of rotatable clip is fixed the main card hoop 11 of semicircular arc on clip arm 9; Two ends at main card hoop 11 semicircular arcs are being provided with hinged ear and Connection Block respectively; Hinged with an end of symmetrical secondary clip 1 its semicircular arc of main card hoop 11 through the hinged ear of bearing pin and main card hoop 11; The engaging lug of the other end of its semicircular arc is connected through the engaging lug of bolt with main card hoop 11; At crossbeam 2 heads the clip seat is being set, the axially extending bore running-fit of clip arm 9 and clip seat, the inhibiting device that clip arm 9 ends are provided with matches with the inner end surface of clip seat.The structure of inhibiting device is installed with bearing pin 10 in clip arm 9 ends radial direction through hole to be set on radial direction through hole, spring cotter is installed on pin shaft hole.Inhibiting device is for to be provided with shoulder block in clip arm 9 ends.The structure of the counterweight of adjusting position is for axially being provided with guide groove on the bottom surface of crossbeam 2 opposite side square tube types; The screw 12 that matches with leading screw 7 is installed in the square tube of crossbeam 2; Screw 12 is connecting roller 8 and is hanging the suspension rod of counterweight 6 through Connection Block; Suspension rod and guide groove running-fit, the lower end of suspension rod fixed counterweight 6, and on its extension arms of leading screw arm of crossbeam 2 afterbody end cap through hole running-fits handle 5 is being set.
Travelling crane hook is hung on the main hanger 3, when load, according to weight mass counterweight 6 is moved to correct position through shaking handle 5, makes suspender keep balance as balance; When zero load, counterweight is moved to the suspender midway location through shaking handle 5, make the crossbeam 2 of suspender remain level thus.When lifting, the Screw of Worm Gear elevator is fixed on the clip, because clip can rotate with crossbeam, therefore the Screw of Worm Gear elevator can be automatically vertically downward when lifting.With on another root steel rope auxiliary connection hanger 4, and make steel rope be in relaxed state, to avoid when unloading, causing tumbling of crossbeam.So can the Screw of Worm Gear elevator easily be sent into and hang out from the vertical mill side.And clip can axially freely rotate relative to crossbeam, therefore can directly the Screw of Worm Gear elevator be blocked in any position, and in the lifting process automatically vertically.
