Description

Technical Field

[0001] This utility model belongs to the field of transportation technology, and in particular relates to a multi-purpose saddle for ultra-large containers. Background Technology

[0002] With the continuous advancement of production processes and the improvement of technology in the petrochemical industry, the trend of increasing the size of pressure vessels in the chemical industry has become increasingly apparent; currently, some large pressure vessel equipment exceeds 100m in height and weighs over 1500t.

[0003] The sheer size of ultra-large containers directly increases the difficulty of equipment manufacturing and transportation. Pressure vessels of various diameters require saddles of varying sizes for support. Traditional saddles are only suitable for a single container size; for equipment with multiple diameters, a large number of saddles and tooling fixtures often need to be manufactured, leading to increased costs and extended production cycles. Ultra-large diameter and ultra-long equipment is not only heavy and bulky, but also requires hydrostatic testing after manufacturing. When filled with water, the total weight of a single piece of equipment can exceed 5,000 tons. A large number of saddles are needed for support before final assembly, but fewer are needed for shipment after pressure testing. Traditional saddles are difficult to disassemble, affecting container transportation. Ultra-large containers are typically manufactured in sections, assembled horizontally on saddles, and then lifted to the required height using hydraulic jacks to facilitate access for transport vehicles. Traditional saddles cannot meet the requirements for lifting and roll-on / roll-off transport.

[0004] Therefore, given the aforementioned characteristics of high cost, difficulty in disassembly, and inability to meet transportation requirements, there is a need to provide a multi-purpose saddle for ultra-large containers to solve the above technical problems. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1 to 3As shown, the multi-purpose saddle for ultra-large containers of this utility model includes a first outer saddle 1, a second outer saddle 2, two inner saddles 4, a connecting assembly 5, and a lifting mechanism 6. The first outer saddle 1 is connected to the second outer saddle 2, or the first outer saddle 1 and the second outer saddle 2 are respectively disposed on both sides of the two inner saddles 4. The two inner saddles 4 are connected and fixed together by the connecting assembly 5. The first outer saddle 1 and the second outer saddle 2, or the two sides of the two inner saddles 4 are respectively connected to the first outer saddle 1 and the second outer saddle 2 by the connecting assembly 5. The lifting mechanism 6 is respectively disposed at the bottom of the first outer saddle 1 and the second outer saddle 2 for lifting and supporting the first outer saddle 1 and the second outer saddle 2.

[0024] Furthermore, in the multi-purpose saddle for ultra-large containers of this utility model, the connecting assembly 5 includes a first mounting plate 51, a second mounting plate 52, a third mounting plate 53, a fourth mounting plate 54, a connecting bolt 55, and a nut 56. The first mounting plate 51 is welded to the inner side of the first outer saddle 1, the second mounting plate 52 is welded to the inner side of the second outer saddle 2, the third mounting plate 53 is welded to the outer side of the two inner saddles 4, and the fourth mounting plate 54 is welded to the inner side of the two inner saddles 4 respectively. The connecting bolt 55 passes through the first mounting plate 51 and the second mounting plate 52 in sequence and engages with the nut 56 threadedly, or the connecting bolt 55 passes through the first mounting plate 51 and the third mounting plate 53 in sequence and engages with the nut 56 threadedly, or the connecting bolt 55 passes through the second mounting plate 52 and the third mounting plate 53 in sequence and engages with the nut 56 threadedly, thereby facilitating quick assembly and disassembly between the first outer saddle 1, the second outer saddle 2, and the two inner saddles 4.

[0025] Furthermore, in the multi-purpose saddle for ultra-large containers of this utility model, the two inner saddles 4 are connected by connecting bolts 55 passing through the two fourth mounting plates 54 on the inner side of the two inner saddles 4 and engaging with nuts 56 by threads.

[0026] Furthermore, in the multi-purpose saddle for ultra-large containers of this utility model, lifting lugs 3 are symmetrically welded to the outer sides of the first outer saddle 1 and the second outer saddle 2, so that the first outer saddle 1 and the second outer saddle 2 can be moved easily when they are disassembled and assembled.

[0027] Furthermore, in the multi-purpose saddle for ultra-large containers of this utility model, the first outer saddle 1 and the second outer saddle 2 are connected and the middle part is set in a small arc groove shape, and the two inner saddles 4 are connected to the first outer saddle 1 and the second outer saddle 2 respectively and the middle part is set in a large arc groove shape, so as to be suitable for supporting containers of various diameters.

[0028] Furthermore, in the multi-purpose saddle for ultra-large containers of this utility model, arc pads 7 are provided on both the small arc groove and the large arc groove, which effectively avoids damage to the container surface during the support and transportation of the container.

[0030] Specifically, the first outer saddle 1, the second outer saddle 2, and the two inner saddles 4 are relatively independent connecting modules. When supporting and lifting a small-diameter large container, the first outer saddle 1 and the second outer saddle 2 are selected. The connecting bolts 55 pass through the first mounting plate 51 and the second mounting plate 52 in sequence and engage with the nuts 56, so that the first outer saddle 1 and the second outer saddle 2 form a saddle with a small arc groove in the middle to support the small-diameter large container. Alternatively, the connecting bolts 55 pass through the first mounting plate 51 and the third mounting plate 53 in sequence and engage with the nuts 56. The threaded engagement and connecting bolts 55 pass through the second mounting plate 52 and the third mounting plate 53 in sequence and engage with the nuts 56, so that the first outer saddle 1, the second outer saddle 2 and the two inner saddles 4 form a saddle with a large circular arc groove in the middle, which supports the large-diameter large container. During the pressure test, multiple sets of saddles can be quickly added according to the length of the container. After the pressure test is completed and before transfer, the connecting bolts 55 and nuts 56 are removed and the excess saddles are quickly removed by the lifting lugs 3. During the transfer, the lifting mechanism 6 lifts the container to the required height for easy transfer.

[0031] In summary, compared with the prior art, the multi-purpose saddle for ultra-large containers of this utility model has the following advantages and beneficial effects:

[0032] This utility model has a simple overall structure and is easy to assemble and disassemble. Through the cooperation between the first outer saddle, the second outer saddle, and the two inner saddles and the connecting components, the number of saddles can be increased or decreased according to the weight and length of the container equipment during use.
