The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage are clearer, below in conjunction with drawings and Examples, the present invention are further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figures 1 to 3, be a preferred embodiment provided by the invention.
Referring to Fig. 1, Fig. 2, a kind of rocking arm lifting crane 1, comprise supporting base 11, clump weight 12, column 13, rocking arm 14 and hoisting device 15, column 13 is connected on supporting base 11; end of rocking arm 14 is connected with the top of column 13; clump weight 12 connects and rotates and be located at the relative both sides on column 13 respectively with rocking arm 14; rocking arm 14 and clump weight 12 centers of gravity are in the same plane position; hoisting device 15 is arranged on rocking arm 14; hoisting device 15 is arranged on the position that rocking arm 14 is connected with column 13, adjacent with column 13 tops and rocking arm 14.
The technical essential of this rocking arm lifting crane 1 embodies a concentrated reflection of in the design of the decorating position of hoisting device 15 and rotational structure, the hoisting device 15 of this rocking arm lifting crane 1 is erected at the junction of column 13 and rocking arm 14, can utilize better the length of rocking arm 14 crossbeams, increase arm of force length, improve lifting efficiency; This rocking arm 14 and clump weight 12 can rotate simultaneously in a circumferential direction, both guaranteed the balance that both go up at an arbitrary position, the use of castor in cooperation, can realize again turning to and moving, thereby easily weight is transported to the workshop anywhere, is adapted to the workshop condition hoisting operation narrow, narrow, that the cleanliness level requirement is high.
Particularly, hoisting device 15 is electric block, comprise reel 151, chain sling 152 and suspension hook 153, the initial end of chain sling 152 is looped around on reel 151, the middle-end of chain sling 152 is passed the crossbeam of rocking arm 14 and is arranged along the length direction extension of crossbeam, chain sling 152 is walked around the pulley of rocking arm 14 beam-ends to downward-extension, and chain sling 152 ends are connected with suspension hook 153.
Driven by motor reel 151 rotates, thus control loop around the convergent-divergent of the chain sling 152 on reel 151, thereby by suspension hook 153 hoisting heavies of chain sling 152 ends.For the weight of small volume, directly weight is fixed on to lifting on suspension hook by lifting rope and gets final product.Electric block carries operating handle, by by key control, easy to operate.
Preferably, column 13 vertically is fixedly connected on supporting base 11De center; rocking arm 14 is rotationally connected with the top of column 13 by bearing, and rocking arm 14 can be around column 13 rotation of 360 ° with clump weight 12, and the center of gravity of rocking arm 14 and clump weight 12 is in the same plane position.
Rotational structure be designed with two schemes: such scheme is that column 13 is fixed on supporting base 11, and rocking arm 14 and clump weight 12 rotate in a circumferential direction around column 13, thereby convenient weight is moved to the anywhere on circumferencial direction.Such rotational structure is more flexible, and shortcoming is that the bearing due to column 13 tops has born larger load, so larger to the wearing and tearing of bearing.The center of gravity of rocking arm 14 and clump weight 12 is remained on to same plane in design process, be also in order to improve the balance while rotating, further to reduce the pressure to bearing as far as possible.
Referring to Fig. 3, preferably, column 13 is connected to supporting base 11De center by rotating disk 131 vertical rotation of bottom; rocking arm 14 is fixedly connected on the top of column 13; column 13 can drive rocking arm 14 and be the rotation of 360 ° around supporting base 11 with clump weight 12, and the center of gravity of rocking arm 14 and clump weight 12 is in the same plane position.
Another scheme of rotation is rocking arm 14 to be fixed on to the top of column 13, then by the bottom at column 13, sets up a rotating disk 131, rotating disk 131 is connected on supporting base 11, thereby drives rocking arm 14 and clump weight 12 rotations.It is not easily that such rotational structure is rotated, but, due to the use that has reduced free bearing, structure is more firm.
Particularly, column 13 is Collapsible structure, comprises original segment 132 and extension 133, and extension 132 is connected in the upper end of original segment 133 by bearing.
The column 13 of rocking arm lifting crane adopts Collapsible structure, the higher weight of convenient extraction, and the overall dimensions of this rocking arm lifting crane 1 is little, generally adapts to short job space, as needs extract higher weight, can realize by setting up extension 132.
Particularly, the bottom of supporting base 11 is provided with castor 111, can support at rectangle, and 11 corner location is installed 4 castors 111, thereby makes rocking arm lifting crane 1 can move to anywhere.
Preferably, have two groups of wheel flutters in castor 111 at least, two groups of wheel flutters can be realized synchronously turning to, and facilitate rocking arm lifting crane 1 to turn to and move to assigned address at narrow, narrow workshop condition.
Further, roller 1111 is parallel combines by several for castor 111, and the castor 111 shown in Fig. 2 is comprised of 2 rollers 1111, also can be made as 3 or 4.
Each castor 111 adopts many wheel designs of a plurality of roller 1111 parallel combinations, and roller 1111 surfaces are elastomeric material, its advantage is to guarantee to turn to flexibly the balanced pressure with having reduced castor 111 and ground unit's area of contact simultaneously, even so just can guarantee that castor 111 can not damage coating floor or other floors that requirement of withstand voltage is arranged as cleaning shop by pressure yet under fully laden.
Particularly, clump weight 12 is located at the top of supporting base 11, and the center of gravity projection of clump weight 12 is in the rectangular area scope that each castor 111 centers of gravity surround.
The volume of clump weight 12 is little, thereby guarantees to make the center of gravity projection of clump weight 12 to be in all the time in the rectangular area of 4 castors, 111 compositions in rotary course.Supporting base 11 does not need support except castor 111 and fixing, and no matter, under unloaded and fully laden, rocking arm 14 can not toppled at 360 ° of direction rotation lifting cranes.
Further, rocking arm lifting crane 1 also is provided with suspender 16, and suspender 16 is connected with the suspension hook 153 of electric block, and suspender 16 is by fixedly weight lifting of lifting rope.
The wide cut coiled strip of installation printing class and the rubber roll of band-type product are generally longer, so the fixedly weight lifting of lifting rope that needs suspender 16 two ends to hang down.
The suitable cleaning shop little in space, that cleanliness level is had relatively high expectations of the rocking arm lifting crane 1 that this invention provides is used, the weight of cleaning shop generally can be too not heavy, only need middle-size and small-size electric block just can lift by crane, can be very not high to the scantling of structure requirement of complete machine yet.This invention has turns to flexibly, mobile hoisting function, is highly suitable for the production on-line operation of cleaning shop.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes of forming all drop on protection scope of the present invention.
