An embodiment of the present invention provides a hoisting tool 10 for hoisting a tubular member 20, and referring to fig. 1 and 5, the hoisting tool 10 includes a plurality of lifting lugs 12 and a tool body 11.
The lifting eye 12 is provided with a lifting hole 12a for passing the first wire rope 30. The hoisting tool 10 is pulled by the first steel cable 30 to move.
The tool body 11 is provided with a mounting through hole 10a for passing through the tubular member 20, and a first bearing surface 11a is provided along one axial side of the mounting through hole 10a, the first bearing surface 11a being adapted to abut against each stopper 21 of the circumferential surface of the tubular member 20 to bear the tubular member 20. Due to the abutting connection of the first bearing surface 11a and the stop block 21, the tubular element 20 cannot pass through the installation through hole 10a, and the movement of the tubular element 20 is restrained, so that the tubular element 20 can move along with the hoisting tool 10. Since the first bearing surface 11a is located at one axial side of the mounting through-hole 10a such that the direction of the interaction force between the first bearing surface 11a and the stopper 21 of the tubular member 20 is along the axial direction of the tubular member 20, the force applied to the tubular member 20 in the radial direction is reduced.
The lifting lug 12 is arranged on the tool body 11. So that the hoisting operation of the tubular member 20 is realized by hoisting the hoisting tool 10.
According to the hoisting tool 10 disclosed by the embodiment of the invention, the first bearing surface 11a is abutted to the stop block 21 along the axial direction of the tubular element 20, so that the first bearing surface 11a can directly bear the gravity of the tubular element 20 in the hoisting process, and the radial acting force applied to the tubular element 20 by the hoisting tool 10 is reduced, thus the deformation of the tubular element 20 is reduced, and the influence on the subsequent construction of the tubular element 20 is reduced; the hoisting tool 10 is simple in structure, easy to manufacture and low in manufacturing, operating and maintaining cost.
It is understood that the specific structural form of the lifting lug 12 is not limited.
For example, the lifting eye 12 is a lifting hook, one end of the first wire 30 is provided with a wire sleeve, and the first wire 30 passes through the lifting hook to connect the first wire 30 with the lifting eye 12; for another example, the lifting eye 12 is a block structure, the lifting hole 12a is a through hole 12, and one end of the first wire rope 30 passes through the lifting hole 12a and then forms a wire rope sleeve, so that the first wire rope 30 is connected with the lifting eye 12.
It can be understood that the size of the mounting through hole 10a, on one hand, needs to satisfy the requirement that the stopper 21 cannot pass through the mounting through hole 10 a; on the other hand, it is necessary to reduce the force of the inner wall of the mounting through-hole 10a against the tubular member 22 of the tubular member 20.
For example, the radius of the mounting through-hole 10a is larger than that of the tube 22, and the radius of the mounting through-hole 10a is smaller than the distance from the outer surface of the stopper 21 in the radial direction to the axis of the tube 22. Namely, the installation through hole 10a is in clearance fit with the pipe body 22, so that the inner wall of the installation through hole 10a is separated from the surface of the pipe body 22, the inner wall of the installation through hole 10a is prevented from directly applying acting force to the pipe body 22, and deformation of the pipe-shaped member 20 caused by the force applied during the hoisting process is reduced.
As another example, the radius of the mounting through-hole 10a is equal to the radius of the pipe body 22. Namely, the installation through hole 10a and the tube body 22 are in transition fit, on one hand, the contact area between the first bearing surface 11a and the stopper 21 is increased, so that the probability of stress deformation of the first bearing surface 11a and the stopper 21 is reduced; on the other hand, the inner wall of the installation through hole 10a is reduced to directly apply a force to the pipe body 22, thereby reducing deformation of the pipe-shaped member 20 caused by the force applied thereto during the hoisting process. In this case, the roundness tolerance of the installation through-hole 10a should be adapted to the roundness tolerance of the tubular member 20.
It will be appreciated that the mounting position of the lifting lug 12 is advantageous in reducing interference between the tubular member 20 and the first wire rope 30, facilitating smooth hoisting operations.
In some embodiments, referring to fig. 1, the lifting lug 12 is disposed on a side of the tool body 11 along a radial direction of the tubular member 20 and away from the installation through hole 10 a. So that the lifting lugs 12 are located away from the tubular member 20, reducing the likelihood of deformation of the tubular body 22 caused by pinching between the first wire rope 30 and the tubular body 22 during lifting.
It will be appreciated that the construction of the lifting tool 10 is optimised to reduce the load on the lifting device during the lifting operation.
In some embodiments, referring to fig. 1 and 2, the tool body 11 is provided with a plurality of weight-reducing holes 111 a. The tool body 11 is convenient to carry and mount, and the load of the hoisting device in hoisting operation is reduced, so that the technical requirements on the hoisting device are reduced, and the operation cost is reduced.
In some embodiments, referring to fig. 1 and 2, lightening holes 111a extend through the tool body 11 in a radial direction of the tubular member 20 to minimize the weight of the tool body 11.
It will be appreciated that the particular configuration of the tool body 11 facilitates the penetration of the tubular element 20 into the mounting through hole 10 a.
In some embodiments, referring to fig. 1 and 3, the tool body 11 includes a plurality of sub-bodies 111, the sub-bodies 111 extend along the circumferential direction of the tubular member 20, and the plurality of sub-bodies 111 are connected end to end along the circumferential direction of the tubular member 20 to form the installation through hole 10 a. The tool body 11 is composed of a plurality of sub-assemblies 111, so that the size of raw materials required by manufacturing the tool body 11 as an integral component is reduced, the material cost is reduced, and the manufacturing process steps are reduced; the split charging body 111 has smaller volume and is convenient to install and transport; adopt a plurality of partial shipment bodies 111 end to end connection in order to form installation through-hole 10a to make tubular member 20 in the in-process that gets into installation through-hole 10a, need not frock body 11 and tubular member 20 to take place relative movement along the axial so that body 22 gets into installation through-hole 10a, and can make partial shipment body 111 install in proper order along circumference so that body 22 is located installation through-hole 10a, thereby reduce work load and activity duration, improved the efficiency of hoist and mount operation.
It can be understood that the specific connection manner between the sub-assemblies 111 is not limited, for example, welding, bolt and nut connection, etc. are adopted, and the connection manner is flexibly selected according to the specific material and structural form of the sub-assemblies 111, so as to reduce the manufacturing difficulty and the manufacturing cost.
It will be appreciated that the specific configuration of the sub-body 111 facilitates increased manufacturing speed and reduced manufacturing costs.
In some embodiments, referring to fig. 1 and 2, the sub-assembly body 111 comprises two bearing plates 1111 and a plurality of connecting plates 1112, the bearing plates 1111 are circular arc shaped extending along the circumference of the tubular member 20, the two bearing plates 1111 are spaced apart along the axial direction of the tubular member 20, the first bearing surface 11a is located on the side of the bearing plate 1111 facing away from the other bearing plate 1111, and the connecting plates 1112 are connected between the two bearing plates 1111 and spaced apart along the circumference of the tubular member 20. Bearing board 1111 and connecting plate 1112 adopt panel to make to reduce manufacturing cost, reduced the manufacturing difficulty, adopt the plate manufacturing to reduce the course of working, the panel connection structure that sets up at interval each other can satisfy bearing strength simultaneously, alleviates partial shipment body 111's structural weight. All set up first loading face 11a on two loading boards 1111, with arbitrary loading board 1111 and dog 21 butt when being convenient for hoist and mount, need not to distinguish the orientation of frock body 11 to improve the efficiency of hoist and mount operation. Through connecting plate 1112, can play the supporting role to bearing plate 1111, reduce the probability that bearing plate 1111 takes place to warp after first bearing surface 11a and dog 21 butt, improve the life of hoist and mount frock 10.
It can be understood that, referring to fig. 1, two adjacent connecting plates 1112 and the part of the carrier plate 1111 therebetween together enclose the lightening hole 111 a.
It will be appreciated that the thickness of the sheet material of carrier plates 1111 and attachment plates 1112 will be configured according to the weight of tubular members 20 to be hoisted, the number of attachment plates 1112, etc.
It can be understood that, during the hoisting process, if the bearing plate 1111 and the connecting plate 1112 deform, the size of the installation through hole 10a changes and the tubular member 20 is pressed, so that the tubular member 20 deforms accordingly, and even a serious person can cause the stopper 21 to be disengaged from the installation through hole 10a and the tubular member 20 falls off, thereby creating a safety hazard. Therefore, the material of the carrier 1111 and the connection plate 1112 needs a certain mechanical strength to reduce the deformation of the carrier 1111 and the connection plate 1112 after carrying the tubular member 20.
The material of bearing plate 1111 and connecting plate 1112 can be stainless steel.
It can be understood that, the specific connection manner between the bearing plate 1111 and the connection plate 1112 is not limited, for example, welding, bolt and nut connection, etc. are adopted, and the specific material and the spaced size of the sub-packaging body 111 are flexibly selected to reduce the manufacturing difficulty and the manufacturing cost.
It can be understood that the arrangement mode between the lifting lug 12 and the separate body 111 can better improve the connection strength between the first steel cable 30 and the hoisting tool 10, and improve safety redundancy.
Specifically, referring to fig. 1 to 3, the connecting plates 1112 include two first connecting plates 1112b and a plurality of second connecting plates 1112a, the two first connecting plates 1112b are located at both ends of the body 111 along the circumferential direction of the tubular member 20, the second connecting plates 1112a are arranged between the two first connecting plates 1112b at intervals along the circumferential direction of the tubular member 20, the lifting lugs 12 are arranged on the first connecting plates 1112b on the side of the tubular member 20 facing away from the mounting through hole 10a in the radial direction, the first connecting plates 1112b are attached to and connected to the first connecting plates 1112b of another adjacent body 111, and the first wire rope 30 passes through the lifting holes 12a of the two lifting lugs 12. The second connection plate 1112a serves to connect the carrier plate 1111 to reinforce the structural strength. The first connecting plate 1112b has the same function as the second connecting plate 1112a, and on the one hand, can be connected with the first connecting plate 1112b of the adjacent sub-assembly to achieve the purpose of connecting the sub-assembly end to end; on the other hand, the bearing plates 1111 of two adjacent sub-assemblies are prevented from being directly connected, and the bearing effect of the tubular member 20 is prevented from being influenced by the stress deformation caused by the connection of the two adjacent bearing plates 1111. The lifting lug 12 is positioned on the first connecting plate 1112b, so that the interference of the lifting lug 12 on the bearing plate 1111 and the stop block 21 is avoided, and the position of the lifting lug 12 on the first connecting plate 1112b is far away from the installation through hole 10a, so that the probability of the interference of the first steel cable 30 connected with the lifting lug 12 and the tubular member 20 can be reduced; in addition, because the two adjacent first connecting plates 1112b are provided with the lifting lugs 12, the acting force exerted by the first steel cable 30 can act on the two lifting lugs 12 at the same time, so that the probability of deformation of the lifting lugs 12 due to overlarge load is reduced, and the safety redundancy is improved.
It can be understood that, each lifting lug 12 is symmetrically arranged on the tool body 11 by taking the axis of the tubular element 20 as a reference, so that the stress of each lifting lug 12 is uniform in the hoisting process, and the risk that the tubular element 20 topples and falls due to deformation and fracture of the lifting lug 12 is reduced.
It will be appreciated that the number of ears 12 is not less than two so as to be symmetrically arranged.
The embodiment of the present invention further provides a hoisting assembly, referring to fig. 1 to 4, the hoisting assembly includes a tubular element 20 and the hoisting tool 10 described in the foregoing embodiment, the tubular element 20 is inserted into the installation through hole 10a, a plurality of stoppers 21 are circumferentially arranged on the surface of the tubular element 20 at intervals, and the first bearing surface 11a abuts against the stoppers 21, so that the hoisting tool 10 bears the tubular element 20 along the gravity direction. The weight of the tubular element 20 is transferred to the hoisting tool 10 through the stopper 21 in the gravity direction, so that the reaction force applied to the tube body 22 of the tubular element 20 is in the gravity direction rather than in the radial direction of the tubular element 20, thereby reducing the probability of deformation of the tubular element 20.
It is understood that the connection manner between the stopper 21 and the tube 22 is not limited, such as screw connection, welding, etc.
In some embodiments, the stopper 21 and the tube 22 are welded, and three-sided welding is adopted, that is, the contact surface between the stopper 21 and the first bearing surface 11a and the tube 22 are not welded, so as to prevent the weld from affecting the contact between the stopper 21 and the first bearing surface 11a and increase the contact area therebetween.
It will be appreciated that the particular shape of stop 21 facilitates the lifting operation of tubular member 20.
In some embodiments, the surface of stop 21 along the radial direction of tubular member 20 is rounded. When the tubular element 20 needs to be lifted and placed in the deep well, and the distance from the stop block 21 to the axis of the tubular element 20 is larger than the radial size of the lifting tool 10, the friction between the stop block 21 and the inner wall of the deep well can be reduced due to the arc-shaped surface of the stop block 21, the probability of blocking of the tubular element 20 in the lifting process is reduced, the lifting quality is ensured, and the construction difficulty is reduced.
It will be understood that in the operation of abutment of the stop 21 against the first bearing surface 11a, the tubular element 20 is in a flat condition, while the tubular element 20 is in a vertical condition during the lifting. Auxiliary structures are provided on tubular member 20 to allow smooth and safe transition of tubular member 20 from a flat position to an upright position.
In some embodiments, a stop 21 is provided at one end of the tubular member 20 and the surface of the other end of the tubular member 20 is provided with an auxiliary tab for a second cable connection required to turn the tubular member 20 over. By simultaneously winding and unwinding the first cable 30 and the second cable, the tubular member 20 is converted from the horizontal state to the vertical state, and the probability of deformation caused by contact with the ground during the conversion process of the end of the tubular member 20 away from the stopper 21 is reduced.
The embodiment of the invention also provides a hoisting method, which comprises the following steps of:
s1: a tubular member 20 is provided, wherein the surface of the tubular member 20 is provided with a plurality of stoppers 21 arranged at intervals in the circumferential direction. Which is tubular member 20 as described in any of the previous embodiments.
