Description

Technical Field

[0001] The present invention relates to the technical field of box-type skid-mounted ceiling structures, and in particular to a ceiling structure capable of being hoisted with the aid of a box-type skid-mounted device. Background Art

[0002] Box-type skid-mounted filling equipment is currently the mainstream product for LNG filling. It has been widely used because of its small footprint, easy installation, complete functions, low investment cost and rapid site construction. The overall weight of a conventional box-type skid-mounted filling equipment is between 40t and 50t, and the end size is generally 3.9m×3.9m. When the box-type skid is lifted, if there is no auxiliary support on the top, it will cause extrusion damage to the box-type skid-mounted box, affecting product quality. At present, external struts, additional auxiliary support for storage tanks, additional auxiliary support inside the skid body and full welding of the ceiling are mostly used to solve the problem of extrusion damage caused by the box-type skid-mounted box.

[0003] When using external support poles, each time the poles are hoisted, they need to be manually sent to the top of the skid and placed manually, which is time-consuming and labor-intensive and has certain safety hazards. Moreover, if they are still placed on the top of the skid after hoisting, there are safety hazards. If they are stored separately, they take up more space.

[0004] Using the storage tank to add auxiliary support and adding reinforcement plates on both sides of the storage tank, although it increases the overall rigidity of the wall and minimizes the risk of deformation of the skid wall, the storage tank is a pressure vessel with a vacuum interlayer. If the tank body is subjected to a large external force, it will inevitably cause certain unknown damage to the tank, which poses a certain safety risk. If this risk is taken into account during the design, the manufacturing cost of the storage tank will inevitably increase. Since the storage tank and the wall are connected, if the connection part needs to be removed when the storage tank is replaced, the construction time will be increased;

[0005] Auxiliary supports are added inside the skid body, which need to be removed one by one during maintenance, increasing the construction time;

[0006] The full ceiling welding is adopted to make the skid body form a complete box structure, and the strength of the skid body itself is used to meet the lifting requirements, but the subsequent maintenance of the storage tank is basically not considered. If the storage tank needs to be replaced, it basically requires a lot of cutting of the skid body to complete it. Summary of the invention

[0007] The present invention aims to provide a ceiling structure that can be assisted by a box-type skid-mounted device for lifting, so as to solve the problems in the prior art that lifting of a box-type skid-mounted box body is prone to squeezing injuries, manual placement is time-consuming and labor-intensive, storage tanks are easily damaged, storage tanks are inconvenient to maintain, and the construction time for replacing storage tanks is long.

[0014] During hoisting, firstly put the steel wire rope on the hoisting point of the above-mentioned skid body. When the steel wire rope lifts the above-mentioned skid body, the steel wire rope is limited on the above-mentioned first hoisting rope slot, the above-mentioned second hoisting rope slot, the above-mentioned third hoisting rope slot, or the above-mentioned fourth hoisting rope slot. The extrusion force of the steel wire rope is applied to the above-mentioned first support rod and the above-mentioned second support rod to prevent the steel wire rope from squeezing and damaging the above-mentioned skid body and the above-mentioned ceiling cover. The above-mentioned ceiling sealing plate is sealed to the above-mentioned ceiling frame, which can not only strengthen the structure but also prevent rainwater from seeping into the interior of the above-mentioned skid body.

[0015] The present embodiment discloses a ceiling structure that can be assisted in lifting by a box-type skid-mounted device, because the first lifting rope slot, the second lifting rope slot, the third lifting rope slot and the fourth lifting rope slot are arranged on both sides of the above-mentioned ceiling frame, which can limit the position of the wire rope and prevent the wire rope from sliding back and forth. At the same time, the first support rod and the second support rod are arranged on the above-mentioned ceiling frame, so that the extrusion force of the wire rope is applied to the above-mentioned first support rod and the above-mentioned second support rod, so as to avoid squeezing and damaging the above-mentioned skid body and the above-mentioned ceiling cover, thereby making the ceiling structure that can be assisted in lifting by a box-type skid-mounted device have the beneficial effects of not easily causing squeezing and damaging the box body when lifting the box-type skid-mounted box, saving time and effort, not easily damaging the storage tank, and conveniently maintaining and replacing the storage tank, and short construction time of the storage tank.

[0018] In this way, the first outer longitudinal beam, the second outer longitudinal beam, the first outer cross beam and the second outer cross beam together form a rectangular frame, so that the roof frame has a preliminary structure. At the same time, it is beneficial to connect the skid body through the first outer longitudinal beam, the second outer longitudinal beam, the first outer cross beam and the second outer cross beam, thereby improving the structural strength of the sealed connection of the roof cover to the skid body.

[0024] In this way, by arranging a plurality of the above-mentioned arc beams in the longitudinal middle part of the above-mentioned ceiling frame, the diameter of the storage tank inside the above-mentioned skid body can be increased to the maximum extent under the condition of a certain height and a certain storage tank volume, shortening the overall length of the equipment, and at the same time, it is conducive to road transportation. When the above-mentioned ceiling sealing plate is welded to the above-mentioned ceiling frame, the top outer surface is convenient for drainage.

[0025] Optionally: a plurality of legs are provided on the inner sides of the first outer longitudinal beam and the second outer longitudinal beam, and the plurality of legs are evenly distributed on the inner side surfaces of the first outer longitudinal beam and the second outer longitudinal beam;

[0032] Optionally: a waterproof rubber strip is provided between the top of the wall and the joint surface of the ceiling frame, and the waterproof rubber strip is tightly attached between the top of the wall and the joint surface of the ceiling frame.

In this way, the safe lifting of the storage tank can be achieved without damaging the outer wall of the equipment, and the product quality can be avoided.

At the same time, the first clamp block 29 and the second clamp block 30 can ensure the gap between the first hanging rope slot 5 and the second hanging rope slot 6, while the third clamp block 32 and the fourth clamp block 33 can ensure the gap between the third hanging rope slot 7 and the fourth hanging rope slot 8.

[0081] A handle 34 is provided at the top end of the first inner longitudinal beam 15 , and the handle 34 is convenient for workers to lift the ceiling frame 4 .

[0082] See also Figures 1 to 11 In this embodiment, by cleverly combining the first support rod 9 and the second support rod 10 with the ceiling cover 2 and through fine structural design, the strength of the ceiling cover 2 is enhanced while meeting the equipment lifting support requirements, and there is no additional installation or welding work, thereby minimizing the manufacturing cost and construction cost. When replacing the storage tank, it is only necessary to lift the ceiling cover 2 to operate, and there is no need to cut the remaining parts.

[0083] See also Figures 1 to 11 In this embodiment, the main operation process of a ceiling structure that can be assisted by a box-type skid-mounted device is as follows:

[0084] First, open the ceiling cover 2. After the main equipment such as the storage tank is installed, close the ceiling cover 2. During the falling process of the ceiling cover 2, it first enters the positioning hole at the top of the wall 21 through the guidance of the pin 20 to ensure that the ceiling cover 2 is in the correct position. At this time, the fixing plate 22 on the ceiling cover 2 coincides with the internal threaded column 23 at the top of the wall 21. Then, it is fixed by tightening the bolts to complete the installation of the ceiling. After all the equipment is assembled, it can be hoisted. The hoisting rope is inserted into the bottom hoisting rod of the skid body 1, and embedded in the first hoisting rope slot 5, the second hoisting rope slot 6, the third hoisting rope slot 7 and the fourth hoisting rope slot 8 before the hoisting operation can be carried out.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
