The E-house electricity distribution room module is typically customized by shipowner customers to match the electrical utilities on the ship.
In order to minimize the lead time of large transport vessels, E-house electrical distribution room modules are typically designed, manufactured, pre-installed and tested at the factory and finally delivered at the dock. When the wharf is delivered, a crane is used for loading the ship.
As known, the hoisting height limit of a crane is about 20m, and the size of a large E-house distribution room module is much larger than that of a conventional E-house distribution room module because the length of the large E-house distribution room module exceeds 25m and the width of the large E-house distribution room module is 8m to 15 m. According to the design structure characteristics of E-house electricity distribution room module, its bottom frame is welded frame construction, has higher structural stability and structural strength than the hutch, consequently, generally designs the hoisting point in the bottom frame both sides of E-house electricity distribution room module. In the prior art, in order to avoid deformation of the distribution room module due to lateral extrusion force during actual hoisting, and to ensure vertical stress of a hoisting point, the distribution room module is generally hoisted by using an upper and a lower layers of balance beams. Although the technical scheme basically meets the hoisting task requirement of the E-house distribution room module, the following problems exist: 1) in the early stage of hoisting, a large amount of manpower and material resources are required to be invested to configure the upper and lower balance beams, and the difficulty in connecting and selecting on-site hoisting riggings is high; 2) the height of a lifting point is strictly required (generally more than 18 m), and the conventional crane is difficult to meet the use requirement; 3) because the hoisting point height is great, the hoisting shaking amplitude is very large, the E-house distribution room module is easy to collide with surrounding obstacles carelessly in the hoisting and translation processes, and finally the hoisting risk is increased. Therefore, a skilled person is urgently needed to solve the above problems.

Detailed Description
In the description of the present invention, it is to be understood that the terms "front", "rear", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
This truss-like frame of lifting by crane and shackle, wire rope and the crane lifting hook suitable for electricity distribution room module are supporting uses to apply to lifting by crane power to electricity distribution room module, in order to hoist electricity distribution room module to the large-scale transport ship by the bank.
The present invention will be described in further detail with reference to specific embodiments, and fig. 1 shows a schematic structural diagram of a truss-type lifting frame applied to a distribution room module in the present invention, and it can be seen that the truss-type lifting frame is composed of several parts, such as a bearing frame 1, a lifting unit 2, and a pulling unit 3. Wherein, the bearing frame 1 is a truss structure and is formed by welding a plurality of pieces of section steel. The hoisting unit 2 is composed of 4 hoisting lifting lugs 21 welded on the top wall of the bearing frame 1 and used for the shackle to penetrate. The pulling unit 3 is composed of 4 pulling lifting lugs which are welded on the bottom wall of the bearing frame 1 and directly apply pulling force to the bottom frame of the power distribution room module. As shown in fig. 2, 3 and 4, the 4 pulling lugs are named as a first left pulling lug 31, a second left pulling lug 32, a first right pulling lug 33 and a second right pulling lug 34, respectively.
Before formal hoisting is performed in advance, 2 force bearing lifting lugs are respectively welded on the left side and the right side of the module underframe of the power distribution room. During formal hoisting, the first left-arranged pulling lug 31, the second left-arranged pulling lug 32, the first right-arranged pulling lug 33 and the second right-arranged pulling lug 34 are respectively connected with each bearing lug in a one-to-one correspondence manner by means of 4 independent steel wire ropes. 2 steel wire ropes are hung from the crane lifting hook, wherein two ends of one steel wire rope are respectively hooked with the first left-arranged pulling lifting lug 31 and the first right-arranged pulling lifting lug 33, and two ends of the other steel wire rope are respectively hooked with the second left-arranged pulling lifting lug 32 and the second right-arranged pulling lifting lug 34. In the formal hoisting state, the first left pulling lug 31, the second left pulling lug 32, the first right pulling lug 33, and the second right pulling lug 34 cooperate to lift the distribution room module (as shown in fig. 6, 7, 8, and 9).
The truss type lifting frame directly achieves the following beneficial effects when the lifting operation aiming at the distribution room module is actually executed:
1) on the premise of ensuring reliable and stable hoisting of the distribution room module, the application of the truss type hoisting frame can greatly reduce the difficulty of connection and selection of on-site hoisting rigging, namely the hoisting auxiliary working hours are reduced, thereby further improving the hoisting efficiency of the distribution room module and further reducing the hoisting cost;
2) the requirement on the height of a lifting point is effectively reduced, the requirements on the type and specification of a crane are further relaxed, and the hoisting operation for large-scale distribution room modules can be met by using the conventional crane;
3) in order to cater for the truss-like lifting frame, the distribution room module is provided with a plurality of lifting points. The distribution room module has extremely small shaking amplitude in the hoisting process under the influence of the height reduction factor of the hoisting point, so that the phenomenon that the E-house distribution room module is easy to collide with surrounding obstacles due to carelessness in the hoisting and translation processes is effectively avoided;
4) the application of the truss type lifting frame not only greatly reduces the application quantity of lifting riggings, simplifies the arrangement mode of the lifting riggings, but also inevitably reduces the waiting time of the crane.
It should be noted that, in order to avoid the phenomenon of inward concave deformation of the enclosure of the electrical distribution room module due to the lateral extrusion force, in the design of the truss-type lifting frame, the opening distance between the first left pulling lug 31 and the first right pulling lug 33 and between the second left pulling lug 32 and the second right pulling lug 34 should be strictly controlled to ensure that the steel wire rope is always far away from the enclosure in the lifting process. Specifically, as shown in fig. 7, 8 and 9, assuming that the opening distance between the first left pulling lug 31 and the first right pulling lug 33 is d1, the opening distance between the second left pulling lug 32 and the second right pulling lug 34 is d2, and the width of the enclosure of the cubicle module is w, then d1 and d2 should both be greater than w by at least 0.5 mm.
As is known, the bearing frame 1 can adopt various design structures to share and transmit the hoisting force, however, a construction scheme with a simple design structure, easy implementation and a low molding cost is proposed herein, which is specifically as follows: as shown in fig. 5, the force bearing frame 1 preferably comprises a main frame 11, a reinforcing component 12 and a shape stabilizing component 13. The main frame 11 is a rectangular frame structure and is formed by end-to-end tailor welding of a front longitudinal beam 111, a right transverse beam 112, a rear longitudinal beam 113 and a left transverse beam 114. The reinforcement assembly 12 is composed of a left reinforcing beam 121 and a right reinforcing beam 122 welded to the inside of the main body frame 11. The shape stabilizing component 13 is composed of a first inclined strut 131 and a second inclined strut 132 which are welded in the main body frame 11 and are mutually crossed. Two-by-two groups of 4 lifting lugs are respectively welded on the first inclined strut 131 and the second inclined strut 132, and 4 lifting lugs are uniformly distributed and welded around the main body frame 11. It should be noted that the bearing frame 1 formed by the above design scheme not only has better structural strength, but also has lighter overall weight, and is beneficial to the transfer operation.
It is known that the hoisting stability and safety of the distribution room module are affected not only by the strength of the overall structure of the truss-type hoisting frame, but also by the stability under stress. In view of this, as a further optimization of the structure of the force bearing frame 1, as shown in fig. 5, the left reinforcing beam 121 and the right reinforcing beam 122 arranged therein are parallel to each other and are both perpendicular to the front longitudinal beam 111 and the rear longitudinal beam 113. The front end of the first diagonal brace 131 is welded to the front longitudinal beam 111 and the left reinforcing cross beam 121 at the same time, and the rear end thereof is welded to the rear longitudinal beam 113 and the right reinforcing cross beam 122 at the same time. The front end of the second diagonal brace 132 is welded to the front side member 111 and the right reinforcing cross member 122 at the same time, and the rear end thereof is welded to the rear side member 113 and the left reinforcing cross member 121 at the same time. Therefore, on the premise of simplifying the design structure of the truss type lifting frame as much as possible, the bearing frame 1 becomes an organic stress body, and the higher structural stability is ensured when the lifting operation is actually executed.
In order to ensure that the left reinforcing beam 121, the right reinforcing beam 122, the first diagonal brace 131 and the second diagonal brace 132 have higher connection strength relative to the main frame 11 during welding and further improve the ultimate stress capacity, as a further optimization of the structure of the bearing frame 1, as shown in fig. 5, a toggle plate reinforcing assembly 14 is further added to the bearing frame 1. The toggle reinforcement assembly 14 includes a first left toggle 141, a second left toggle 142, a center toggle 143, a first right toggle 144, and a second right toggle 145. Wherein, the first left toggle plate 141 is simultaneously contacted and welded with the front longitudinal beam 111, the left reinforcing beam 121 and the first inclined strut 131; the second left toggle plate 142 is simultaneously contacted with the rear longitudinal beam 113, the left reinforcing cross beam 121 and the second inclined strut 132 in a sticking way and welded; the central toggle plate 143 is simultaneously contacted with the first diagonal brace 131 and the second diagonal brace 132 and welded; the first right toggle plate 144 is simultaneously contacted with the front longitudinal beam 111, the right reinforcing cross beam 122 and the second diagonal brace 132 and welded; the second right toggle 145 is simultaneously in contact with the rear longitudinal beam 113, the right reinforcing cross beam 122, and the first diagonal brace 131, and welded thereto.
As can be clearly seen from fig. 5, the force-bearing frame 1 is further provided with a first deformation preventing component 15, a second deformation preventing component 16 and a third deformation preventing component 17. The first deformation preventing member 15 is formed of 4 pieces of first reinforcing rib plates 151 welded to diagonal regions of the body frame 11. The second anti-deformation component 16 is used for enhancing the connection stability of the left reinforcing cross beam 121 and the main body frame 11, and is composed of 2 pieces of second reinforcing rib plates 161 which are respectively welded with the front longitudinal beam 111 and the left reinforcing cross beam 121 in a one-to-one correspondence manner and are simultaneously welded with the rear longitudinal beam 113 and the left reinforcing cross beam 121. The third deformation prevention component 17 is used for enhancing the connection stability of the right reinforcing cross beam 122 and the main body frame 11, and is composed of 2 third reinforcing rib plates 171 which are respectively welded with the front longitudinal beam 111 and the right reinforcing cross beam 122 in a one-to-one correspondence manner and are simultaneously welded with the rear longitudinal beam 113 and the right reinforcing cross beam 122. Therefore, the structural stability of the truss type lifting frame can be further improved, and the instability phenomenon caused by unbalanced force in the lifting process is avoided.
In order to verify the reasonability of the design structure of the truss type lifting frame, fig. 10 also shows a stress analysis diagram of the truss type lifting frame suitable for the power distribution room module in the utility model when the lifting operation is carried out.
Finally, it should be noted that the specific arrangement positions of the first left-disposed pulling lug 31, the second left-disposed pulling lug 32, the first right-disposed pulling lug 33, and the second right-disposed pulling lug 34 may be finely adjusted according to the width value of the pre-hoisted distribution room module. For example, when the hoisting operation of the small-width power distribution room module needs to be performed, the opening distance between the first left-placed pulling lug 31 and the first right-placed pulling lug 33 and between the second left-placed pulling lug 32 and the second right-placed pulling lug 34 needs to be adaptively reduced, and of course, the adjustment of the opening distance may also be implemented by increasing the number of the first left-placed pulling lug 31, the first right-placed pulling lug 33, the second left-placed pulling lug 32, and the second right-placed pulling lug 34 by multiple times, and selectively supporting the wire rope thereon in the later period, so as to ensure that the opening angle of the wire rope is controlled within a reasonable value range (as shown in fig. 11).
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
