Description
Technical field
The utility model relates to a kind of device that improves the curved stability of movable crane band idling.
Background technology
Large-scale mobile hoisting crane, especially caterpillar telescopic boom crane can't guarantee that when band idling is curved its stability is the greatest problem of restriction hoisting crane load capacity.Can produce the side direction force of inertia because hang when band idling is curved to carry, influence the lateral stability of complete machine, complete machine is turned on one's side easily.
The utility model content
Can not be with carrying or the problem of dead slow speed walking in little year for solving large-scale mobile device solution.
The utility model provides a kind of device that improves the curved stability of movable crane band idling, comprises stable stirrup, steel rope, hangs and carry, draw to hang and carry that a steel rope, jib, hoist rope, turning gear, running gear, vertical amplitude oil cylinder, side direction open oil cylinder, connect crossbeam, regulate oil cylinder, band ratchet elevator; Running gear carrying turning gear, turning gear carrying jib, jib support hoist rope and draw to hang and carry a steel rope, and hinged stable stirrup in the middle of the jib stablize stirrup other end mounting strap ratchet elevator, and band ratchet elevator year is connected with hanging by steel rope; Stablize the nearly jib end of stirrup and be provided with the connection crossbeam, stablize stirrup and be connected between crossbeam installation side and stablize between stirrup and jib amplitude oil cylinder is installed to opening oil cylinder.
Described stable stirrup is 2, and 2 stable stirrups are identical.
Described steel rope is connected or directly year is connected with hanging with hanging to carry by pulley.
Beneficial effect: the utility model provides a kind of device that improves the curved stability of movable crane band idling, increase the curved stability of movable crane band idling, solving some large-scale mobile hoisting crane can not be with carrying walking or problem that can only dead slow speed walking in little year.Be applicable to the operation field that rotating speed is not high, lifted load is bigger.

The specific embodiment
This device act as increases the curved stability of movable crane band idling, and solving some large-scale mobile hoisting crane can not be with carrying or the problem of dead slow speed walking in little year.Shown in Fig. 1 to 2:
Before using this device, should be according to the device installation site, detailed calculated stablize stirrup 1 tensioning angle and assurance and is hung years 3 positions in the vertical direction.
Stablize stirrup 1 and carry 3 and is connected with hanging, and guarantee to be with the folding and unfolding of ratchet elevator 13 to connect this device by stablizing stirrup 1 hanging to carry before 3 in advance.
Task of the present utility model is, allows hanging of movable crane to carry 3 and reinforces by steel rope 2, wherein guarantees to connect to hang to carry two steel ropes 2 of 3 and have identical length, thereby can bear the side force of the generation when complete machine is turned that produces equably.In the case, guaranteed that steel rope 2 reinforcing conditions are more reliable and at any time can both realize regulating again.
According to the utility model, a kind of stable stirrup 1 is provided, these stable stirrup 1 one ends have and are articulated and connected a little, and are hinged with jib 5, and the other end has band ratchet elevator 13, and that can realize stretching out from this elevator carries stretching of 3 steel ropes that are connected 2 with hanging.Steel rope 2 is stablized the interior hydraulic ram of stirrup 1 and is connected with being arranged in by being arranged in to hang to carry the pulley (or assembly pulley) on 3 and be arranged in the pulley (or assembly pulley) stablized on the stirrup.
The utility model provides a kind of device that improves the curved stability of movable crane band idling, comprises stablize stirrup 1, steel rope 2, hanging and carry 3, draw to hang and carry a steel rope 4, jib 5, hoist rope 6, turning gear 7, running gear 8, vertical amplitude oil cylinder 9, side direction and open oil cylinder 10, connect crossbeam 11, regulate oil cylinder 12, be with ratchet elevator 13; Running gear 8 carrying turning gears 7, turning gear 7 carrying jibs 5, jib 5 support hoist rope 6 and draw to hang and carry steel rope 3, hinged stable stirrup 1 in the middle of the jib 5, stablize stirrup 1 other end mounting strap ratchet elevator 13, band ratchet elevator 13 by steel rope 2 with hang years 3 and be connected; Stablize stirrup 1 nearly jib 5 ends and be provided with connection crossbeam 11, stablize stirrup 1 and be connected 11 installation sides of crossbeam to opening oil cylinder 10, stablize 5 of stirrup 1 and jibs vertical amplitude oil cylinder 8 are installed.
