Description

Improved rapid loading and unloading hoist

The utility model relates to a kind of fast loading and unloading type high building hoisting crane, belongs to miniature hoisting crane field.

Existing high building hoisting crane generally is confined to be installed in the positive operation of house balcony, and need get the fixed position and install.Though install the fixed position of need not getting that has, but adorn, tear open very inconvenient; In addition, most types can not realize making the function of weight in being forwarded to by outward turning, bring sense of insecurity to the operator.

The purpose of this utility model provides the high building hoisting crane of a kind of Fast Installation and dismounting, a kind of laborsaving, convenient, safety is provided for the vast resident family on high building, and can realize the handling facility that many families are shared, simultaneously again for being engaged in the desirable facility that a kind of vertical transport is provided for the personnel of the industry of high building resident family carrying heavy goods service and office on no elevator high building, production or construction operation.

Be that I applied for and obtained that Patent Office of the People's Republic of China was on February 20th, 1991 on January 19th, 90 above, the utility model patent of authorizing---the preface of " fast loading and unloading type high building hoisting crane " (patent No. 90211059.4) specification sheets, it is applicable to the utility model " improved fast loading and unloading type high building hoisting crane " fully.

Below in conjunction with accompanying drawing this type is carried out detailed narration.

Fig. 1 is an embodiment of the present utility model---the structural representation of improved fast loading and unloading type high building hoisting crane.

Fig. 2 be among Fig. 1 A to view.

Fig. 3 is a B-B cutaway view among Fig. 1.

Shown in 1,2,3, the utility model is made up of three big parts such as support section, elevator rotating part and the parts that hoists with reference to the accompanying drawings.Support section is made of following (1) seat of honour (11), gasket ring (12), strut (8), nut (3), push rod (2).Strut (8) bottom dress push rod (2), and in the seat of honour (11) are supportted at two ends, in the middle of the following seat (1), elevator (5) and pulley bracket (10) kink are loaded on the strut, rising arm (16) one ends are loaded on the piece (7) that axle (6) is gone up and is supported on and elevator is connected as a single entity on the elevator, and steel cable (14) is drawn from elevator and walked around pulley (13) and with top the suspension hook (19) of facing upward arm platen (18) is housed with (17) and links to each other.When swivel nut (3), force push rod (2) that its outside thread cooperates with nut (3) stretch owing to its upper surface and the lower surface of strut (8) fit tightly along the guider screw of strut (8) below, thus the ball-and-socket that the bulb by spacer member (8) two ends holds out against (or unclamping) upper and lower again by canvas filler rubber gasket ring (12) and up and down basal plane fit tightly.

The elevator rotating part colludes (15) etc. by elevator (5), split plain bearing partial bearing lid (4), fixed pulley (13), support (10), shoulder (9) and steel cable (14), secondary rope and forms.Semicircle orifice on partial bearing lid (4) and elevator (5) left surface forms plain bearing, and its lower surface is supported on the shoulder of (8) below; Elevator is by a pair of gear reduction reinforcement, and guiding principle rope (14) is wrapped on the reel that connects firmly with passive big gear wheel.Miniature gears is connected with a ratchet in case unexpected accidental counter rotation.Be loaded on the axle of support (10) fixed pulley (13) cantilever.

Support is connected with strut (8) plain bearing and holds on shoulder (9), and the pair rope with anticreep pawl colludes (15) and hangs the jail on the lateral pin of support (10) by the guiding principle rope of fixed length.The part that hoists by rising arm (16), fixed pulley (17), face upward arm platen (18), drop hanger (19) etc. and form.The rising arm left end is the semicircle bearing of a V shape opening, it can be around axle (6) rotation of being fixed in elevator top, and moment (when weight gentlier and not adopts pair to collude) rising arm right-hand member fixed pulley axis (22) both sides fixed sides (20), (21) that the piece (7) on the elevator was limited and bore weight for the extreme lower position of rising arm, they become half-surrounded to pulley but stay an opening on the right, so that steel cable can pass in and out, and opening adorns one and has the anticreep of torsion spring to collude, and the bottom of biside plate constitutes a plane a.Face upward arm dish (18) and be hung on the end of elevator steel cable (14), hang drop hanger (19) on its below ring ear, its end face make a plane b in case weight rise to certain altitude after b contact with a, can safe area rising arm (16) and continue to raise, thus around rotating shaft (6) swing.

When operation is installed, at first base (1) is placed down the basal plane left side, then handstand bar (2) and nut (3) of the right hand.Left hand is taken strut (8) vertically the seat of honour (11) to be affixed on and is made the following ball-and-socket of push rod bulb aligning under the top base, set upright strut then and use right hand dextrorotation turn nut (3), so push rod stretches out stretching in the ball-and-socket of seat up and down, remove jack panel (3) with the subsidiary moving rod of this machine again, then strut and building one integrated mass are enough to bear the tilting complex torque of weight.Second step elevator that split bearing has been opened sticks in the strut and the lower surface is held on the lower shoulder of strut (8), closes up fastener rapidly, screws fly nut.The 3rd step, insert the prong of rising arm in the rotating shaft (6) and be pressed on and prop up on the piece (7), at this moment, just can collude pair (15) mouth and catch on horizontal bar in the rising arm up, then the drop hanger steel cable is pulled out, the interior continuation of groove that hangs over fixed pulley (13) earlier elongates the guiding principle rope and is hung in fixed pulley (17) groove, so far all installs.Anti-jiggle bar can put down drop hanger and get weight (this moment ratchet should at disengaged position) so that hang.When collude get weight after, ratchet is closed miniature gears and cw jiggle bar, then weight rise, when rising to the b face of facing upward arm platen (18) and contact with rising arm a face, continue to shake handle, weight is together steeved together with rising arm and is realized the luffing of arm, after rising arm is put certain angle, and can be rising arm together with weight, elevator pulley bracket steel cable etc. rotates to suitable position together, so the separation ratchet, anti-jiggle bar, weight descends together with rising arm.First round operation so far finishes.The rising arm of steeving makes it to forward to the outside, can prepare second and take turns operation.

The advantage of the utility model crane is as follows: one, the scope of application has been widened greatly. Because this machine can support and be fixed in uneven two basal planes, so can be loaded on the windowsill, also can be loaded on the outrigger below of balcony or the dead ahead in logical corridor. This has just got rid of a lot of limitations, and various selections are provided: the balcony front is the luggage side not, and balcony is the luggage windowsill not; This window is that window of luggage not; Its two, weight can rotate, and brings the sense of security and convenience to operation; Its three, maximum characteristics are to realize Fast Installation and dismounting. This machine is from installing support section, and to putting down drop hanger, omnidistance needs 2 minutes, and one man operation need not additional means, for frequent transfer tasks place provides convenience. In addition, complete machine is light and handy, rapid operation, and cost is low, and is space-saving.
