It is understood that the terms "a" and "an" should be interpreted as meaning that a number of one element or element is one in one embodiment, while a number of other elements is one in another embodiment, and the terms "a" and "an" should not be interpreted as limiting the number.
Referring to fig. 1 to 8, a combined lifting appliance for single-hook lifting four-point suspended offshore booster station according to a preferred embodiment of the present invention can be mounted on a single hook 40 and can be used for lifting a lifted object 900 with four lifting eyes 50 in a rectangular distribution.
The combined lifting appliance for the single-hook lifting four-point suspended offshore booster station comprises a horizontal frame 20, wherein the upper part of the horizontal frame 20 can be suspended from the single hook 40 through a lifting rope 10, and the lower part of the horizontal frame 20 can be provided with a lifting piece 30, such as a lifting hook, for lifting the lifted piece 900.
The horizontal frame 20 includes two cross bars 22, two longitudinal bars 23, and four connecting assemblies 24. The two ends of each cross bar 22 are connected to the lower part of one of the connecting members 24. Both end portions of each of the vertical bars 23 are connected to a lower portion of one of the connecting members 24, respectively, in such a manner that the two cross bars 22, the two vertical bars 23, and the four connecting members 24 connected to each other are substantially rectangular in plan view, as shown in fig. 5 and 6.
When a hoisted member such as a booster station is hoisted, the lower portion of each of the connecting members 24 faces one of the lifting lugs 50 of the hoisted member 900. In this way, the combination sling for single-hook four-point suspended offshore booster station can pass through the four lifting members 30 mounted at the bottom of the connecting assembly 24 for subsequent suspension of the four lifting lugs 50 on the lifted member 900.
Preferably, four lifting ropes 10 and four lifting elements 30 are connected to the horizontal shelf 20. The lower end of each hoist line 10 is mounted to the connection assembly 24, the upper end of each hoist line 10 is suspended from the single hook 40, and the upper ends of four hoist lines 10 are held on the central axis of the horizontal frame 20, so that when the single hook 40 lifts the lifted object 900 by the horizontal frame 20, the levelness of the lifted object 900 can be ensured, and the lifted object 900 is prevented from tilting.
It should be noted that, because both ends of each cross rod 22 are respectively connected to the lower portion of one of the connection assemblies 24, and both ends of each longitudinal rod 23 are respectively connected to the lower portion of one of the connection assemblies 24, the positions where the cross rods 22 and the longitudinal rods 23 are respectively connected to the connection assemblies 24 are at different heights, so that the whole combined lifting appliance for single-hook lifting four-point suspended load offshore booster station forms a two-stage self-balancing lever structure. Specifically, each side of the two parallel cross bars 22 constrains a longitudinal bar 23, two connecting assemblies 24 connected to two ends of the longitudinal bar 23, in a lever manner; likewise, two parallel longitudinal bars 23 constrain, on each side, one transverse bar 22, two connecting assemblies 24 connected to the two ends of the transverse bar 22, in a lever-like manner. Thus, the levelness of the horizontal frame 20 can be ensured, so that the lifted object 900 can be vertically stressed when the lifted object 900 is lifted subsequently.
Preferably, both ends of the cross bar 22 and the longitudinal bar 23 are hinged to the coupling assembly 24 so that the cross bar 22 and the longitudinal bar 23 can be rotated by a predetermined angle with respect to the coupling assembly 24, respectively. In this way, the horizontal shelf 20 can occupy a smaller space when stored.
Specifically, each of the connecting members 24 includes a main body 241, an upper pin 242 and a lower pin 243. An upper through hole is formed in the upper end of the body portion 241 in the width direction. Two ends of the vertical rod 23 are respectively provided with a vertical rod notch, and in addition, a vertical rod pin hole is arranged on the side wall forming the vertical rod notch.
The upper through hole of the main body portion 241 is aligned with a side wall of the side bar notch of the side bar 23. The upper pin 242 is inserted into the side rail pin hole and the upper through hole so that the side rail 23 and the connecting member 24 are hinged to each other. In one example, the upper end of the main body portion 241 is inserted into the side rail notch such that the upper through hole of the main body portion 241 is aligned with a side rail pin hole of a side wall of the side rail notch of the side rail 23.
Preferably, an upper notch is formed at an upper end portion of the body portion 241, wherein the upper through hole is disposed on a sidewall forming the upper notch. Thus, after the upper pin 242 is inserted into the vertical rod pin hole and the upper through hole, the upper pin 242 may form a first annular hanging space, so that the lower end of the lifting rope 10 may be hung on the upper pin 242. In a modified embodiment, the end of the side rail 23 is inserted into the upper notch such that the upper aperture of the body portion 241 is aligned with a side rail pin hole in a side wall of the side rail notch of the side rail 23.
Preferably, a rotatable member 244, such as a rolling pulley, is sleeved on the upper pin 242, so as to facilitate the lower end of the lifting rope 10 to be sleeved on the rotatable member 244. Thus, it is possible to effectively prevent the hanging rope 10 and the pin 243 from being severely worn due to long-term use.
A lower through hole is formed in the lower end of the body portion 241 in the width direction. The two ends of the cross bar 22 are respectively provided with a cross bar notch, and in addition, a cross bar pin hole is arranged on the side wall forming the cross bar notch.
The lower bore under the body portion 241 is aligned with the rail pin hole on the side wall of the rail notch of the rail 22. The lower pin 243 is inserted into the cross bar pin hole and the lower through hole to hinge the cross bar 23 and the connection assembly 24 to each other. In one embodiment, the lower end of the body portion 241 is inserted into the rail notch such that the lower bore under the body portion 241 is aligned with the rail pin hole on the sidewall of the rail notch of the rail 22.
Preferably, a lower portion of the main body portion 241 forms a lower notch, wherein the lower through hole is disposed below a sidewall forming the lower notch. In this way, after the lower pin 243 is inserted into the cross bar pin hole and the lower through hole, the lower pin 243 may form a second hooking space in a ring shape, so that the upper end of the lifting member 30 may be subsequently hooked to the lower pin 243. In a modified embodiment, the end of the crossbar 22 is inserted into the lower end of the main body 241 to form a lower notch, such that the lower through hole of the main body 241 is aligned with the crossbar pin hole on the sidewall of the crossbar notch of the crossbar 22.
It is worth mentioning that when the horizontal frame 20 is used to lift the to-be-lifted member 900, the extending direction of each connecting assembly 24 forms an angle with the plane formed by the cross bar 22 and the longitudinal bar 23, and the intersection point of the extending directions of the four connecting assemblies 24 is maintained at the center of the horizontal frame 20 which is substantially rectangular in top view.
In this way, it can be ensured that the pulling force of the lower end of the lifting rope 10 and the pulling force of the lifted object 900 (such as the four-point suspended load boosting station) received by the lifting object 30 can be maintained on a vertical plane during lifting. In this way, the two-stage self-balancing lever structure formed by the cross bar 22, the longitudinal bar 23 and the connecting assembly 24 effectively prevents the horizontal frame 20 from shaking as a whole, and the lifting direction of each lifting member 30 can be kept in the vertical direction all the time.
Preferably, the cross bar 22 and/or the longitudinal bar 23 are each configured as a length-adjustable bar, so that the size of the horizontal frame 20 can be adjusted according to the distance between the lifting lugs 50 on the lifted object 900, thereby enabling the horizontal frame 20 to be adapted to various sizes of the lifted object 900.
In one embodiment, the crossbar 22 includes two crossbar bodies 221, a replaceable crossbar 222, and two first connecting members 223 for connecting the crossbar bodies 221 and the replaceable crossbar 222. Both ends of the replaceable rail 222 are detachably fixed to one end of a rail body 221 through one of the coupling members 223, respectively. While the other end of each of the crossbar bodies 221 is always kept hinged to the body portion 241 of the connecting assembly 24.
In this way, it is possible to achieve an adjustable length of the transverse bar 22, i.e. to make the transverse bar 22 implemented as the length-adjustable bar.
Similarly, the side rail 23 includes two side rail bodies 231, an exchangeable side rail 232, and two second connecting members 233 for connecting the side rail bodies 231 and the exchangeable side rail 232. Both ends of the replaceable side rail 232 are detachably fixed to one end of a side rail body 231 through one of the connection members 233, respectively. While the other end of each of the side rail bodies 231 is always kept hinged to the body portion 241 of the connecting member 24.
In this way, it is possible to achieve an adjustable length of the side rail 23, i.e. to implement the side rail 23 as the adjustable length rail.
It is understood that the first connection member 223 and the second connection member 233 may be respectively implemented as a flange.
Preferably, the horizontal shelf 20 further comprises at least one auxiliary rod 21, wherein both ends of the auxiliary rod 21 are connected to the two cross rods 22. Preferably, the horizontal frame 20 comprises at least two auxiliary rods 21, wherein two ends of at least one auxiliary rod 21 are disposed between two cross rods 22, and two ends of the auxiliary rod 21 are respectively connected to one cross rod 22. Both ends of at least one of the auxiliary bars 21 are disposed between the two longitudinal bars 23, and both ends of the auxiliary bar 21 are connected to one of the longitudinal bars 23, respectively.
More preferably, when the cross bar 22 and/or the longitudinal bar 23 are respectively provided as a length-adjustable bar, the auxiliary bar 21 is also implemented as a length-adjustable bar.
In a preferred embodiment, the lower ends of the four lifting ropes 10 for the four-point suspended offshore booster station combination lifting appliance for single-hook lifting are each connected to the hitching space of one of the connection assemblies 24. The upper ends of the four lifting ropes 10 can be hung on the single hook 40 in an intersecting manner, so that the single hook lifting can be realized subsequently.
It should be noted that, during lifting, the extending direction of the lifting rope 10 is collinear with the extending direction of the main body 241 of the connecting assembly 24, so that the levelness of the horizontal frame 20 during lifting can be effectively ensured.
It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are given by way of example only and are not limiting of the invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and described in the examples, and any variations or modifications of the embodiments of the present invention may be made without departing from the principles.
