Detailed description of the invention
The embodiment of hoisting crane in the utility model: as shown in Figure 1 to Figure 3, this hoisting crane is a kind of overhead crane with electric hoists, be made up of the bridge type beam be arranged in plant floor and the double-beam trolley be arranged on bridge type beam, bridge type beam is provided with the twin beams track extended before and after twice, and double-beam trolley along the longitudinal direction guiding movement is assemblied on the guide pass of this twin beams track.Double-beam trolley is again be made up of traveling gear and lifting mechanism, and wherein lifting mechanism is formed primarily of suspension hook, rope, rope drum and lifting motor, and traveling gear is made up of trolley frame, front wheel spindle 1, hind axle 2, front vehicle wheel 3, rear wheel 4 and movable motor 5.Trolley frame comprises left support plate 61, right support plate 62, rear sleeve 63, anterior cannula 64, front wheel carrier 65, the left and right both ends of the surface that left support plate 61 and right support plate 62 are assemblied in rope drum are respectively parallel to each other, rear sleeve 63 is assemblied in the rear portion of left support plate and right support plate by the direct bracketing of mode be welded and fixed, anterior cannula 64 is assemblied in the front portion of left support plate and right support plate by the indirect bracketing of front wheel carrier 65, front wheel carrier 65 is fixed on two fixed beams 66 of the time interval between left support plate and right support plate by bridge joint, the hinge 67 that bridge joint is fixed on the extension of in the middle part of two fixed beams 66 and front and back and the axis extended around front and back rotate the portable beam 68 be assemblied on hinge 67 and form, portable beam 68 is fixed on the upside of the outer peripheral face of anterior cannula 64, and portable beam 68 is hinged between two fixed beams 66 by hinge 67 around the axis that front and back extend, be assemblied on fixed beam 66 by hinge 67 bracketing to make portable beam 68.
Anterior cannula 64 and rear sleeve 63 are the pipe that left and right extends.Front wheel spindle 1 is installed on axis that the bearing that assembles in anterior cannula 64 and by the port at anterior cannula about 64 two ends makes front wheel spindle 1 extend around left and right and rotates and be assemblied in anterior cannula 64, the two ends, left and right of front wheel spindle 1 are stretched out from the left and right two-port of anterior cannula 64, sponson is equipped with respectively by key connection is spin-ended the front vehicle wheel 3 coordinated with twin beams track, and because of front wheel spindle 1 be passive rotation under the promotion of trolley frame, so front vehicle wheel 3 is the driven wheel of whole double-beam trolley.Hind axle 2 is installed in rear sleeve 63, and be assemblied in rear sleeve 63 by the axis rotation that the bearing that the port at rear sleeve about 63 two ends is assembled makes hind axle 2 extend around left and right, the two ends, left and right of hind axle 2 are stretched out from the two ends, left and right of rear sleeve 63, sponson is equipped with respectively by key connection is spin-ended the rear wheel 4 coordinated with twin beams guide rail, and be connected on the movable motor 5 on the right-hand member being fixed on rear sleeve 63 by link span at hind axle 2 upper driving, output shaft and the hind axle 2 of movable motor 5 are coaxially arranged, can rotate under the driving of movable motor 5 to make hind axle 2, so rear wheel 4 is adhesion wheels of whole double-beam trolley.
In lifting mechanism, rope drum is assemblied in the position between left support plate 61 and right support plate 62, and lifting motor be assemblied in right support plate 62 right panel face on position before movable motor 5, thus whole lifting mechanism is integrated on traveling gear.
The phase dorsal part of anterior cannula 64 and rear sleeve 63 is fixed with the energy disperser 69 of opposing extension respectively, and the energy disperser 69 on same sleeve pipe has two and is arranged symmetrically on the periphery at two ends, left and right of sleeve pipe.
In the present embodiment, the lifting mechanism of double-beam trolley adopts fixed type steel-wire rope type electric block, the pivot flange at cucurbit frame two ends is thickeied, adds left support plate 61 and the right support plate 62 of the trolley frame of wonderful works double-beam trolley.The design concept of the current European hoisting crane of design reference of traveling gear, adopt larger axis to hold and comparatively trundle (as: double-beam trolley of rated load weight 10t adopts the wheel of φ 160mm, the bearing of 22310TN1/W33, bearing maximum outside diameter φ 110mm), the employing of this structure makes when bearing rated load increases, improve the speed of travel of double-beam trolley, and less wheel makes the height reduction of whole dolly.Movable motor 5 and the actuating device residing for lifting motor all adopt three-in-one reducing motor.Wheel shaft adopts hollow shaft structure, to increase its transmitting torque.
In the above-described embodiments, rear sleeve is assemblied in the rear portion of two stay bearing plates by the direct bracketing of mode be welded and fixed, in other embodiments, rear sleeve also can by rear wheel frame indirectly bracketing be assemblied in the rear portion of two stay bearing plates, now rear wheel frame also can adopt articulated structure, to ensure that double-beam trolley can pass through by pulsation-free when fluctuating place of twin beams track is more frequent.
In the above-described embodiments, forward and backward sleeve pipe is pipe, and in other embodiments, forward and backward sleeve pipe also can be square tube etc., and the corresponding mode by the two ends installation shaft bearing at forward and backward sleeve pipe realizes and bearing fit.
In the above-described embodiments, movable motor is fixed on rear sleeve by link span, and in other embodiments, movable motor also can be fixed on right support plate, and now the output shaft of movable motor namely can be parallel with hind axle, also can with hind axle spatial intersecting.
In the above-described embodiments, the movable motor that double-beam trolley is connected by hind axle upper driving drives, in other embodiments, double-beam trolley also can mode manually drive, now by assembling sprocket wheel spin-ended on wheel shaft, supply operating personal Non-follow control double-beam trolley advancing on twin beams track by the ring chain that sprocket wheel assembles.
The embodiment of double-beam trolley of the present utility model: in the present embodiment, the structure of double-beam trolley is identical with the structure of double-beam trolley in above-described embodiment, therefore repeats no more.
The embodiment of trolley frame of the present utility model: in the present embodiment, the structure of trolley frame is identical with the structure of trolley frame in above-described embodiment, therefore repeats no more.
