[0058] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0059] Embodiment 1

[0060] like Figure 1 As shown, it is a schematic diagram of the use state of the vertical tank translation introduction device of the present invention; the vertical tank translation introduction device comprises:

[0061] A towing trailer 50 adapted to carry at least one leg 11 of the tank 10;

[0062] A track 70, wherein the track 70 is suitable for guiding the weight transfer device 60 that carries the traction trailer 50 to move; and

[0063] The clamping support assembly 20 is suitable for clamping at least one leg 11 of the tank body 10 when the tank body 10 is moved into position, and by abutting against the lifting member 40, the tank body 10 is raised and lowered by the lifting force of the lifting member 40, so that the tank body 10 is installed in place.

[0064] The vertical tank translation introduction device provided by the present invention can translate and introduce the vertical tank. By turning the vertical tank over and standing it up outside the factory, and using the translation introduction method, the defect of the prior art that the vertical tank cannot be turned over and put into place inside the factory due to the limited installation space of the vertical tank in the factory can be overcome. Simple transfer tools can be used to solve complex installation problems, reduce the difficulty of installation, bring new installation ideas to construction operations, and can be widely used in a large number of similar construction needs. At the same time, it has the characteristics of simple operation, low safety risk, short construction period, and less investment of construction personnel; it avoids the need to drill holes in the roof, hang hand winches, and block holes, and does not require the reservation and slow construction of roof wall columns and other structures, creating favorable conditions for the continuity of civil construction.

[0065] Combination Figure 5 , Figure 6 As shown, Figure 5 is a top view of the traction trailer of the present invention, Figure 6 It is a front view of the towing trailer of the present invention. The towing trailer 50 includes: a support frame 52, and a towing point 51 arranged on the front side of the support frame 52. The support frame 52 is used to support the legs 11 of the tank body 10. The contact position between the support frame 52 and the legs 11 is made of cross-welded steel, and the legs 11 and the support frame 52 are fixed by bolts. By setting the towing trailer 50, on the one hand, it is convenient to support the tank body 10. On the other hand, the towing point 51 is arranged on the front side of the support frame 52, so that the force position is transferred to the towing trailer 50, so as to avoid the traction force directly acting on the legs 11 of the tank body 10, which causes uneven force and reduces the risk of overturning of the vertical tank body.

[0066] Preferably, the support frame 52 is made of I-beams that are cross-welded into a cubic structure.

[0067] Combination Figure 4As shown, it is a schematic diagram of the layout of the track of the present invention; the track 70 includes a guide rail 71 horizontally arranged along the length direction. Preferably, the track 70 includes two guide rails 71 arranged in parallel, and the two guide rails 71 are connected and fixed by a third reinforcement part 72. Preferably, the guide rail 71 is a groove structure. By placing the heavy object transporter 60 in the guide rail, it is convenient to guide the walking path of the heavy object transporter 60, avoid the uncertainty caused by the unplanned movement of the heavy object transporter 60, ensure that the vertical tank body is always subjected to the inertial force in the same direction during the movement, and reduce the risk of overturning.

[0068] At the same time, placing the weight transporter 60 in the guide rail 71 can prevent sand and gravel from entering the weight transporter 60 and causing structural wear when the weight transporter 60 is moved on a non-concrete floor. In addition, laying the track 70 on a concrete floor and placing the weight transporter 60 in the guide rail 71 can increase the force-bearing area and reduce the pressure, thereby preventing the weight transporter 60 from being damaged by excessive local pressure when the weight transporter 60 is loaded and moved.

[0069] Further integration Figure 4 As shown, a plurality of foundation embedded parts 83 are arranged between two rows of building bodies 81, and the foundation embedded parts 83 are used to install and fix the tank body 10. The tank body 10 is installed in the factory by welding or bolting the legs 11 of the tank body 10 to the foundation embedded parts 83. The track 70 is laid between the two rows of building bodies 81 and on the foundation embedded parts 83.

[0070] The present invention introduces the vertical tank body by translation, turns the vertical tank body over and stands it up outside the factory, and then transports it along the track 70 through the heavy object transfer device 60, to tow the vertical tank body placed on the traction trailer 50 to the foundation embedded part 83 in the factory, and finally uses the clamp support assembly to vertically install the vertical tank body in place on the foundation embedded part 83.

[0071] As a specific implementation form, the vertical tank translation introduction device involved in the present invention is described in detail below, taking the actual use situation as an example. Three vertical rubber-lined tanks are installed between two rows of buildings 81 on the 0m floor of the factory building. The tank diameter is 3300mm, the height is 5050mm, the tank top is 0.9m away from the upper concrete beam, the equipment net weight is 20t, the equipment foundation elevation is 0m, and the installation form is that the foundation embedded parts are welded and fixed with the equipment legs. By reserving the outer wall of two rows of buildings 81 in the factory building as the equipment introduction port, two tracks 70 made of [36 channel steel are laid on the ground between the two rows of buildings 81 on the 0m floor of the factory building. Preferably, the length of the guide rail 71 is 30m, the center distance between the two guide rails 71 is 1514mm, and one [8 channel steel is welded every 6m between the two guide rails 71 as the third reinforcement part 72 for connection and fixation. During the welding process of the guide rail 71, it is required to grind the weld meat at the joint connection to smoothen the rail joint misalignment ≤1mm and the rail span deviation ≤10mm. Place thin wooden boards at uneven locations on the ground, adjust the height deviation of the same section of the two guide rails 71 to ≤5mm, and adjust the track levelness to ≤1mm / m.

[0072] Preferably, the support frame 52 is made by cross-welding I22b I-beams into a cubic structure, and two traction points 51 with a tensile force greater than 2t are welded on the front side of the support frame 52. Four 60t heavy object movers are placed on the track 70, that is, two heavy object movers are placed on each guide rail 71, and a traction trailer 50 is placed on the heavy object mover, and the traction trailer 50 and the heavy object mover 60 are spot welded and fixed. Two 2t hanging points 82 are installed near the ends of the two guide rails 71 in the length direction, and the hanging points 82 are fixed to the ground by expansion bolts. The hanging point 82 is connected to the traction trailer 50 by a 2t shackle, a 2t hand winch and a wire rope. A 70t truck crane and a 25t truck crane are used outside the factory to lift the vertical tank body and turn it over to stand. The 70t truck crane hoists the vertical tank body onto the traction trailer 50 and places it steadily. The four legs 11 of the equipment are firmly connected to the traction trailer 50 by bolts, and the heavy object mover is firmly spot welded to the traction trailer 50. After the truck crane is unhooked, two 2t hand hoists are started at the same time to pull the vertical tank body to the top of the foundation embedded part 83. Then the translation of the vertical tank body is realized.

[0073] Embodiment 2

[0074] This embodiment provides a clamp support assembly, combined with Figure 2 , Figure 3 As shown, Figure 2 This is a front view of the clamp support assembly of the present invention. Figure 3 The top view of the clamp support assembly of the present invention; the clamp support assembly comprises:

[0075] A clamping portion 21 adapted to be detachably connected to at least one leg 11 of the tank body 10;

[0076] The support portion 25 has a first end fixedly connected to the first end of the clamping portion 21 , and a support surface abutting against the lifting member 40 is formed at the bottom of the support portion 25 .

[0077] The clamp support assembly used in the present invention is designed for a vertical tank body through a special lifting device, which facilitates the vertical tank body to be installed vertically in place by cooperating with the lifting member 40 after the vertical tank body is introduced into place by translation. At the same time, the clamp support assembly provided by the present invention cleverly utilizes the characteristics of the vertical tank body with the support legs 11, and sets the connection part on the support legs 11, which not only ensures that the working height is relatively low and is convenient for workers to operate; it can also be convenient for clamping, without clamping the side wall of the tank body, reducing the damage to the side wall of the tank body and reducing the difficulty of clamping.

[0078] Specifically, the clamping portion 21 is formed by splicing and enclosing at least two sheet units, the enclosed cross section matches the cross section of the leg 11, and the clamping portion 21 is arranged to penetrate along the length direction. By setting the clamping portion 21 as a multi-piece structure, it is convenient for workers to fix the clamping portion 21 on the leg 11 by assembling, avoiding the construction inconvenience caused by sleeve installation and other methods, and increasing the installation flexibility. The clamping portion 21 is suitable for clamping the leg 11. By setting the clamping portion 21 to a shape that matches the leg 11, it is convenient to bear force during the clamping process, avoiding shaking, dislocation and other loose clamping situations.

[0079] As a specific implementation of the above-mentioned clamping portion 21, the cross-sectional shape of the clamping portion 21 can be circular, square, triangular or other cross-sectional shapes, and its shape preferably matches the shape of the leg 11 to facilitate clamping of the leg 11.

[0080] Specifically, two adjacent edges of the sheet-like units are provided with locking portions 22 outwardly along the width direction; and the two adjacent locking portions 22 are fixedly connected by at least one locking member 24. By providing the locking portions 22 on the edges of the sheet-like units, and further fixing the two adjacent locking portions 22 by the locking members 24, the connection and fixation of the two adjacent sheet-like units are achieved, and the clamping portion 21 forms a stable clamping space, which facilitates the connection and fixation of the clamping portion 21 and the leg 11.

[0081] As another improved implementation, the clamping portion 21 includes two sheet-like units, wherein one side edge of the two sheet-like units is connected by a hinge, and the other side edge is connected by a bolt.

[0082] Preferably, when the cross-sectional shape of the clamping portion 21 is circular, the locking portions 22 are both provided radially outwardly at the edges of two adjacent sheet-like units.

[0083] Specifically, the clamp support assembly also includes a diagonal brace 28, the two ends of which are respectively fixedly connected to the second end of the clamp 21 and the second end of the support 25, so that the clamp 21, the support 25 and the diagonal brace 28 form a stable triangular structure, so that the clamp support assembly has higher structural strength, is not easily damaged under stress, and improves construction safety. Preferably, the angle between the diagonal brace 28 and the upper surface of the support 25 is α, where 0°<α<90°.

[0084] Specifically, the bottom of the support part 25 is further provided with an anti-tilt part 27, which is constructed as a cylindrical structure, which is suitable for being sleeved on the outside of the lifting member 40 and connected with the lifting member 40 by clearance fit or transition fit. Preferably, the anti-tilt part 27 is fixed to the bottom of the support part 25 by welding. When the lifting rod of the lifting member 40 abuts against the support surface formed at the bottom of the support part 25, the connection support can be more stable, the lifting member 40 can be prevented from tipping over, and the construction safety can be improved.

[0085] Specifically, at least one first reinforcement part 23 is provided between the sheet-like unit and the locking part 22 connected thereto. The first reinforcement part 23 acts as a reinforcing rib to ensure the firmness of the connection between the sheet-like unit and the locking part 22, thereby avoiding breakage and deformation, and ensuring that the clamping part 21 is always in a clamping state when connected to the leg 11, and is not easily damaged, thereby improving construction safety.

[0086] Specifically, at least one second reinforcement portion 26 is further provided on the support portion 25 . The second reinforcement portion 26 acts as a reinforcement rib to ensure the structural strength of the support portion 25 .

[0087] Specifically, a cushion layer is provided between the clamping portion 21 and the leg 11. The cushion layer can play an anti-slip role on one hand, reducing the relative sliding between the clamping portion 21 and the leg 11, and can protect the paint on the leg 11 on the other hand. Preferably, the cushion layer can be made of soft materials such as rubber pads, polyurethane pads, polytetrafluoroethylene pads, etc.

[0088] Specifically, the connection part between the diagonal brace part 28 and the support part 25 is arranged vertically corresponding to the connection part between the support part 25 and the anti-tilt part 27. The corresponding arrangement enables the clamp support assembly to be evenly stressed when it abuts against the lifting member 40, thereby ensuring the structural strength.

[0089] As a specific implementation form, the following further describes the clamp support assembly of the present invention in detail based on the example mentioned in the first embodiment and taking the actual usage as an example. The seamless steel pipe is cut and separated, and then heated and bent to make the inner diameter of the cut steel pipe reach 330mm to obtain two arc-shaped sheet units; further Four 500×120×15mm steel plates are welded on the seamless steel pipe, that is, a locking portion 22 is welded on each of the four edges of the two arc-shaped sheet units, the steel plate and the steel pipe are fully welded, and five holes are drilled on each steel plate. and four triangular steel plates are welded between each steel plate and the steel pipe to form a first reinforcement part 23; further An 800mm long H-shaped steel is welded on the seamless steel pipe, that is, the support part 25 is welded at the first end of the clamping part 21, and the steel specification is H200×200×8×12. Furthermore, a steel pipe with a diameter of 133mm and a length of 20mm is welded at the bottom of the steel, that is, the anti-tilt part 27 is welded at the bottom of the support part 25 to prevent the jack from tipping over; 6 vertical ribs are welded at the web of the H-shaped steel to enhance the structural strength of the H-shaped steel. One H-shaped steel is welded on the top Seamless steel pipe, The other end of the seamless steel pipe is welded and fixed to the second end of the clamping part 21.

[0108] As a specific implementation form, based on the examples mentioned in Embodiment 1 and Embodiment 2, the following further describes in detail the method of using the vertical tank translation introduction device involved in the present invention by taking actual usage as an example.

[0109] S1: Place 4 60t heavy object movers on the hauling track, place a traction trailer on the heavy object movers, and fix the trailer and heavy object movers by spot welding.

[0110] S2: Use a 70t truck crane and a 25t truck crane to lift the vertical tank outside the factory, turn it over and make it stand upright. The 70t truck crane lifts the vertical tank onto the traction trailer and places it steadily. The four legs of the vertical tank are firmly connected to the trailer with bolts, and the heavy object mover is firmly spot welded to the trailer.

[0111] S3: Two 2t lifting points are installed on the two tracks near the 5th axis. The lifting points are fixed to the ground with expansion bolts, and the lifting points are connected to the traction trailer with 2t shackles, 2t hand winches and wire ropes. After the truck crane is unhooked, two 2t hand winches are started at the same time to pull the vertical tank body to the top of the embedded foundation parts.

[0112] S4: Install the clamp support assembly on the four legs of the vertical tank body, and place rubber pads between the clamp support assembly and the legs for anti-slip and paint protection.

[0113] S5: Arrange temporary steel piers under the clamp support assembly, and arrange 50t screw jacks between the steel piers and the clamp support assembly. After the four jacks are lifted simultaneously to full stress, remove the hand winch used for traction.

[0114] S6: Grind off the welding points on the vertical tank legs, traction trailer, and heavy object mover, then lift the vertical tank by 10mm using 4 jacks at the same time.

[0115] S7: Manually drag out the heavy object transporter and the trailer, cut and remove the track above the embedded parts of the foundation, and place temporary steel piers and steel plates under the vertical tank legs for secondary protection.

[0116] S8: The four jacks are slowly lowered at the same time, and the secondary protective steel plates are gradually withdrawn as they are lowered. In this step, four people must be assigned to measure the lowering height with a steel tape measure, and the lifting commander coordinates the lowering speed of the jacks.

[0117] S9: When it falls back to 10mm from the minimum stroke of the jack, stop falling back, use temporary steel piers and steel plates to provide secondary protection for the vertical tank body, and the four jacks slowly fall back, using secondary protection to participate in the load-bearing.

[0118] S10: Three jacks remain stationary, the fourth jack falls back, the steel support pier under the fourth jack is removed, the jack is repositioned and lifted to the stress state. The steel support piers under the other three jacks are removed one by one using the same method.

[0119] S11: Four jacks are used to lift the steel piers by 10 mm at the same time, and the secondary protection steel piers are removed, and steel plates are used for secondary protection again.

[0120] S12: The four jacks are slowly lowered at the same time, and the secondary protective steel plates are gradually withdrawn as the lowering progresses, until the vertical tank is lowered back to the foundation, completing the work of hauling the vertical tank into place. In this step, four people must be assigned to measure the lowering height with a steel tape measure, and the lifting commander must coordinate the lowering speed of the jacks.

[0121] Preferably, the specific method of making the steel pier is: using Eight steel piers are made of seamless steel pipes, and a 300×300×20mm steel plate is welded above and below the steel piers. The final height of the steel piers after completion is 160mm.

[0122] The method for introducing a vertical tank provided by the present invention can introduce the vertical tank by translation. By turning the vertical tank over and standing it outside the factory, and introducing the vertical tank by translation, the defect in the prior art that the vertical tank cannot be turned over and put into place inside the factory due to the limited installation space of the vertical tank in the factory can be overcome. Simple transport tools can be used to solve complex installation problems, reduce the difficulty of installation, bring new installation ideas to construction operations, and can be widely used in a large number of similar construction needs. At the same time, it has the characteristics of simple operation, low safety risk, short construction period, and less investment of construction personnel; it avoids the need to drill holes on the roof to hang hand winches and block holes, and does not require the reservation and slow construction of roof wall columns and other structures, creating favorable conditions for the continuity of civil construction.

[0123] Embodiment 4

[0124] As the clamp support assembly described above, this embodiment continues to calculate the load conditions of the clamp support assembly based on the examples mentioned in Embodiment 1 and Embodiment 2.

[0125] First, the force of the connecting bolts used to connect the two adjacent locking parts 22 is calculated. The net weight of the vertical tank is 20t, that is, Q = 20 × 9.8 = 196kN. The bolts are subjected to shear force, and the force of a single leg is R = Q / 4 = 49kN. Each clamping part is installed with 5 bolts, and each bolt is subjected to shear force Fs = R / 5 = 9.8kN. Shear stress [τ] = δs / Ss, coefficient Ss = 2.5, and the yield strength of 8.8-grade bolts δs = 640Mpa (medium carbon steel) is obtained from the table. [τ] = 256Mpa is calculated from the above formula, then 4Fs / (πds2) ≤ 256Mpa, so ds ≥ 6.98mm, so bolts above M8 are selected to meet the needs. The above 8.8-grade bolts of M20 × 150 are selected to meet safety requirements.

[0126] Then the force of the clamp support assembly is calculated. The net weight of the vertical tank is 20t, and the weight is borne by the clamp support assembly of the four legs, that is, each clamp support assembly needs a lifting force of 5t to lift the vertical tank. The force diagram of a single clamp support assembly is as follows: Figure 7 shown.

[0127] From the equilibrium equation ∑F y =0, F1·sin28°-F=0, and we get From the equilibrium equation ∑F x =0, F1·csc28°-F2=0, the solution is F2=10.65×csc28°=9.32t.

[0128] The steel used in F1 is Seamless steel pipe, cross-sectional area A = 797.2mm2, radius of gyration ρ = 2.566cm, length 549mm, material Q235B, allowable stress [σ] = 160MPa. Its slenderness ratio is λ = L / ρ = 54.9 ÷ 2.566 = 21.4, and the reduction factor is obtained by looking up the table The compressive stress is Meet the needs of use.

[0129] The steel used at F2 is H200×200×8×12 steel, with a cross-sectional area of ​​A=6208mm2, a radius of gyration ρ=5.07cm, a length of 485mm, a material of Q235B, and an allowable stress of [σ]=160MPa. Its slenderness ratio is λ=L / ρ=48.5÷5.07=9.6, and the reduction factor is obtained by looking up the table The compressive stress is Meet the needs of use.

[0130] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
