The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The application provides a hoisting equipment, wherein, the hoisting equipment includes revolving stage 10, mast 20, super lift 30 and strutting arrangement 40, super lift 30 include with revolving stage 10 articulated super lift mast 31, strutting arrangement 40 is the rigid structure, strutting arrangement 40 connect respectively in mast 20 and super lift mast 31 in order to form the triangle-shaped structure with mast 20 and super lift mast 31, strutting arrangement 40 one end set up can with revolving stage 10 and contact in order to transmit super lift 30's counter weight 32's load.
With the lifting apparatus of the present application, when not lifted or the lifting weight is light, the weight of the counterweight 32 of the superlift device 30 can be transferred to the turntable 10 through the support device 40, thereby keeping the counterweight 32 from falling to the ground. Therefore, by keeping the counterweight 32 from falling to the ground all the time, it is possible to adapt to more work places and improve efficiency.
Wherein, the supporting device 40, the mast 20 and the super lift mast 31 form a stable triangular structure, which can satisfy different states of the lifting device. For example, when the super lift mast is raised (the tip of the super lift mast 31 faces the front of the lifting equipment), the support device 40 provides a pulling force between the mast 20 and the super lift mast 31, and when the super lift is carried out (the tip of the super lift mast 31 faces the rear of the lifting equipment), the support device 40 bears between the mast 20 and the super lift mast 31.
In addition, the supporting device 40 forms a stable triangular structure with the mast 20 and the super mast 31, and can realize that:
the supporting device 40 does not interfere with relevant components such as the super lifting mast 31 and the like;
the movement track of the mast 20 is ensured to be fixed, so that the contact position of the supporting device 40 and the rotary table 10 is determined.
Wherein the supporting device 40 can be in various suitable forms as long as it is a rigid structure to be able to bear and pull as required. For example, the support device 40 may be a truss structure. Alternatively, the support device 40 may be a ladder frame structure.
In addition, the support device 40 may be selected to have different lengths according to the position where the support device 40 is connected to the super lift mast 31. To this end, the support means 40 may be provided to be capable of varying in length, for example the support means 40 may be in a telescopic form. Preferably, for convenience of arrangement, as shown in fig. 2 and 3, the supporting device 40 may include at least two segments 41 sequentially connected in a length direction of the supporting device 40. Wherein adjacent segments 41 may be secured to each other by any suitable means, such as by snapping or by a pin. In the embodiment shown in fig. 2 and 3, the ends of the segments 41 are provided with mounting seats 42 to connect with adjacent segments 41 by means of mounting seats 42 and pins 43.
In addition, the support device 40 may be attached to the superlift mast 31 at a suitable location, for example, one end of the support device 40 may be attached to the top of the superlift mast 31. Alternatively, one end of the support device 40 may be connected to the middle of the superlift mast 31.
In this case, one end of the supporting device 40 may be always in contact with the turntable 10, but when the hoisting weight is large, the counterweight 32 does not need to transmit the load to the turntable 10 through the supporting device 40. Therefore, it is preferable that the supporting device 40 is provided to be capable of switching between a pressurized state contacting the turntable 10 and an unpressurized state spaced apart from the turntable 10 according to a change in the lifting weight of the lifting apparatus. Specifically, when the hoist weight is large, the supporting device 40 may be spaced apart from the turntable 10; when the hoisting weight is small or not, the counterweight 32 needs to be suspended, and the support device 40 is in contact with the turntable 10. This can be achieved by adjusting the angle of the superlift mast 31.
The support device 40 can be attached to the mast 20 at a suitable location, such as at the end of the mast 20. As shown in fig. 4, one end of the mast 20 may be provided with a first connection seat 21 for connection with the superlift mast 31, and the other end of the mast 20 may be provided with a second connection seat 22 for connection with the support device 40. In order to provide support during rotation and avoid wear of parts in contact with one end of the support means 40 caused by rotation of the support means 40 as parts such as the mast 20 pivot about the turntable 10 during use, the turntable 10 is provided with a contact slot 11 in rotational contact with one end of the support means 40. Preferably, the contact groove 11 may be arc-shaped (for example, a contact seat 10a having an arc-shaped contact groove 11 may be provided on the turntable 10), one end of the supporting device 40 may be provided with a third connecting seat 44, and the third connecting seat 44 may be provided with a pin P, as shown in fig. 5, when the weight of the hoisting weight is small or in a non-hoisting state, a part of the weight of the counterweight 32 is used for balancing the hoisting weight, and at this time, the supporting device 40 bears and forms a semi-articulated contact with the turntable 10 through the contact groove 11 to transmit the pressure to the turntable 10, so that the counterweight 32 still does not fall to the ground (i.e., is suspended).
When the lifting weight is different, the distance between the counterweight 32 and the position of the main machine where the turntable 10 is located needs to be adjusted (for example, when the lifting weight is large, the counterweight 32 is farther from the turntable 10 as shown by a solid line in fig. 1, and when the lifting weight is small, the counterweight 32 is suspended, and the counterweight 32 is closer to the turntable 10 as shown by a dotted line in fig. 1). To this end, the hoisting device may include a super-lift weight luffing apparatus 60 to adjust the distance between the counterweight 32 and the turntable 10.
According to one embodiment of the present application, as shown in fig. 1, the super lift weight luffing apparatus 60 is hinged at one end to the turret 10 and at the other end to a pulling plate 33 that is connected to the weight 32 of the super lift apparatus 30. Specifically, the super-lift counterweight luffing device 60 may include a first folding arm 61 and a second folding arm 62 hinged to each other, and a first telescopic cylinder 64 having two ends hinged to the first folding arm 61 and the second folding arm 62, respectively, wherein the distal end of the first folding arm 61 is hinged to the rotary table 10, and the distal end of the second folding arm 62 is hinged to the pulling plate 33. The first folding arm 61 can be rotated relative to the second folding arm 62 and the second folding arm 62 can be rotated relative to the turntable 10 by the first telescopic cylinder 64 to adjust the position between the counterweight 32 and the turntable 10.
According to another embodiment of the present application, as shown in fig. 6, the super-lift counterweight amplitude variation device 60 may include an amplitude variation folding arm 63 and a second telescopic cylinder 65, wherein two ends of the amplitude variation folding arm 63 are respectively hinged to the mast 20 and the pulling plate 33, and two ends of the second telescopic cylinder 65 are respectively hinged to the amplitude variation folding arm 63 and the mast 20. The mast 20 can replace the second folding arm 62, so that the number of folding arms is reduced, and the cost is saved.
Similar to the prior art, the hoisting device of the present application further includes a front arm 70, a superlift mast anti-back-tilt rod 34, a wire rope connecting the front arm 70 and the superlift mast 31, and the like, which will not be described in detail herein.
