Description

Technical Field

[0001] The utility model relates to an industrial device, in particular to a chemical construction device, specifically an auxiliary device for assembling a spherical tank. Background Art

[0002] The assembly construction of steel spherical storage tanks takes a 3000m³ spherical tank as an example. The spherical tank is a hybrid structure of ten columns and three belts, with a total of 1128 assembly square caps. Assembly fixtures, square pins and round pins are used to assemble them. The traditional assembly method is to hang the fixture on the square cap before hoisting the spherical shell plate, fix it with round pins, and then use square pins to assemble and adjust the seams after the spherical shell plate is hoisted into place. During the hoisting process, it is very easy for the pins to fall off, which poses a great safety hazard. When assembling and adjusting the seams, the riveter needs to hit the square pins with a sledgehammer so that the assembly gap, misalignment and edge angle of the spherical shell plate meet the specification requirements. The whole process consumes a lot of physical energy for the workers, and it is easy to lose the hammer and the pins fall off.

[0003] Therefore, there is an urgent need for a device that is simple and fast, can provide its own power, has low operating risks, and has high labor efficiency, so as to better meet construction needs. Utility Model Content

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 and 2 shown.

[0019] The utility model discloses an auxiliary device for assembling a spherical tank, which comprises a clamping slot 1 and a plugging plate 4.

[0020] The slot 1 is a rectangular block, on which a longitudinal through seam 3 and a transverse first through hole 2 are provided. One side of the through seam 3 is through, so that the transverse end face of the slot 1 is a horizontal U-shape. The first through hole 2 is a rectangular long hole, which is centrally arranged and passes through the slot. Preferably, the slot 1 can be formed by welding two steel plates of 250mm×100mm×12mm at one end, and a through seam is formed between the two plates. The first through hole 2 is about 50mmx100mm.

[0021] The plug plate 4 is in the shape of a flat plate, and its shape is equivalent to the through slit 3. Its thickness is slightly smaller than the width of the through slit 3, so that it can be movably inserted into the through slit 3. The plug plate 4 is provided with a second through hole 5 that passes through its plate surface. The second through hole 5 is a rectangular long hole, arranged in the center, and its size is equivalent to the first through hole, so that when the plug plate 4 is placed in the through slit 3, the first through hole 2 and the second through hole 5 are connected to form a mounting hole. Preferably, the plug plate 4 can be made of a steel plate of 250mm×100mm×12mm.

[0022] The slot 1 and the plug plate 4 are respectively provided with a connection structure. The connection structure includes a support rod 6 and a connecting rod 7, both of which are in the shape of straight rods. One end of the support rod 6 and the connecting rod 7 are connected to form an L-shaped structure, and the distal end of the support rod 6 is connected to the end of the slot 1 or the end of the plug plate 4, and the distal end of the connecting rod 7 is a suspended end. The support rod 6 is perpendicular to the slot 1 or the plug plate 4, which is convenient for installation and use. The orientation of the connecting rod 4 is consistent, which is convenient for use. At the same time, the cross-section of the connecting rod 7 is rectangular or circular, which is smaller than the size of the hole of the square cap 10 on the spherical shell plate 9, so that the connecting rod can be easily inserted into the hole of the square cap and can move slightly in the square cap.

[0023] The position of the connection point between the support rod 6 and the slot 1 or the plug plate 4 is adapted to the distance between adjacent square caps when the spherical shell plate 9 is installed, so that when the plug plate and the slot are installed to the spherical shell plate, there is a slight lateral misalignment between the first through hole and the second through hole, creating conditions for the subsequent relative movement of the slot and the plug plate.

[0024] The method of using the utility model is:

[0025] Insert the plug plate into the slot to complete the assembly. Then, insert the connecting rod on the plug plate and the connecting rod on the slot into the square caps of the two adjacent spherical shell plates respectively. Subsequently, place a hydraulic jack 8 of suitable size in the mounting hole, and make the base and the push rod of the jack rest against the side of the second through hole and the side of the first through hole respectively. The jack is controlled by a control device, so that the slot and the plug plate move toward each other with the pushing action of the jack, driving the spherical shell plates to move, so that the gap between the spherical shell plates is adjusted. The jack can be a hydraulic jack, and it is controlled by a wire control device.

[0026] After the gap adjustment is completed, another jack is placed between the slot and the spherical shell plate, so that the base and the push rod of the jack are placed on the bottom surface of the spherical shell plate and the slot respectively. Since there is a certain gap between the connecting rod and the square cap, the slot can be moved vertically slightly under the pushing action of the jack, and the adjacent spherical shell plate can be moved vertically, thereby adjusting the misalignment and edge angle of the spherical shell plate. During the entire operation, the operator only needs to operate the control device to easily achieve the assembly of the spherical shell plate.

[0027] The utility model can complete the grinding work of the spherical shell plate through the hydraulic jack, so that the assembly gap, misalignment and edge angle of the spherical shell plate meet the requirements of the specification, greatly reducing the labor load of personnel and improving the construction efficiency. At the same time, it can also eliminate the risks of hammer falling off and pin falling off in the past, and fully meet the construction needs.

[0028] The parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art.
