Ordinary transformer oil tank suspension shafts have problems such as difficult processing, complex welding and assembly, and poor reliability and stability. In addition, ordinary suspension shafts are directly welded to the tank wall. Since the gravity of large bell-shaped or barrel-shaped oil tanks is very large during lifting, excessive stress concentration points will be generated at the welding position between the tank wall and the suspension shaft, and the force will be transmitted to the tank wall, causing the risk of deformation of the tank wall. Therefore, it is necessary to design a suspension shaft structure to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figure 1-Figure 3 The utility model discloses an oil tank suspension shaft structure, comprising:

[0025] The reinforcing iron 7 is fixed to the outer surface of the tank wall 6; the first fixed plate 4 is fixed to one side of the reinforcing iron 7, and the largest area of ​​the first fixed plate 4 is in contact with the reinforcing iron 7; the pulling plate 1 is fixed to the side of the reinforcing iron 7 away from the first fixed plate 4, and the pulling plate 1 and the reinforcing iron 7 are vertically arranged; the hanging shaft 3 passes through the first fixed plate 4 and the reinforcing iron 7 and is fixed to the first fixed plate 4 and the reinforcing iron 7, the circumferential side surface of the hanging shaft 3 is also fixed to the pulling plate 1, and a clamping plate 2 is fixed to one end of the hanging shaft 3 close to the pulling plate 1, and a second fixing plate 5 is fixed to the other end of the hanging shaft 3.

[0026] Among them, multiple oil tank hanging shafts can be welded on the oil tank, and the number is determined according to actual needs. The oil tank hanging shaft as a whole is fixed to the oil tank reinforcement iron 7 through the first fixing plate 4 and the pulling plate 1, wherein the pulling plate 1 plays a role in enhancing the mechanical strength and makes the lifting and transportation of the oil tank more portable. The card plate is then fixed to the protruding side of the hanging shaft 3, and then the second fixing plate 5 is welded to the other end of the hanging shaft 3, and finally the reinforcement iron 7 is welded to the wall of the oil tank, so that the hanging shaft structure is not directly in contact with the wall 6, thereby reducing the risk of stress concentration on the wall and structural deformation; in addition, the structure has high mechanical strength and can better meet the needs of the oil tank during lifting and transportation.

[0027] In addition, the fixing connection method among the pull plate 1, the clamping plate 2, the hanging shaft 3, the first fixing plate 4 and the second fixing plate 5, the box wall 6 and the reinforcing iron 7 is preferably but not limited to welding.

[0028] The reinforcing iron 7 is C-shaped and has two fixed ends, which are fixed to the box wall 6; the hanging shaft 3 passes through the connecting plate between the two fixed ends of the reinforcing iron 7, the first fixed plate 4 is in contact with the connecting plate, and the pulling plate 1 is vertically fixed to the connecting plate; the first fixed plate 4 and the second fixed plate 5 are arranged in the space between the two fixed ends of the reinforcing iron 7.

[0029] Specifically, the suspension shaft 3 passes through the connecting plate between the two fixed ends of the reinforcing iron 7, and the first fixing plate 4 and the second fixing plate 5 are fixed in the space formed between the two fixed ends of the C-shaped reinforcing iron 7. The interval between the first fixing plate 4 and the second fixing plate 5 and the space formed between the two fixed ends of the C-shaped reinforcing iron 7 can better limit the deviation of the rope used for transportation or lifting, thereby fixing the suspension shaft 3 more firmly, thereby improving the stability of the oil tank during transportation or lifting.

[0030] The pull plate 1 is also provided with a through hole, through which a locking rope passes.

[0031] The diameter of the through hole needs to be set according to the actual area of ​​the pull plate 1 to ensure that the pull plate 1 will not be irreversibly damaged during a certain period of use. At the same time, the rated service life of the pull plate 1 and the through hole should be calibrated.

[0032] A gap is arranged between the first fixing plate 4 and the second fixing plate 5 , and a locking rope is wound around the hanging shaft 3 in the gap.

[0033] Reference Figure 1 and Figure 2 The diameter of the clamping plate 2 is larger than the cross-sectional diameter of the hanging shaft 3 , and a protrusion is provided on the clamping plate 2 in a direction away from the pulling plate 1 .

[0034] A gap is arranged between the protrusion of the clamping plate 2 and the first fixing plate 4, and a locking rope is clamped in the gap.

[0035] Among them, the protrusion and the gap between the protrusion and the first fixed plate 4 are used to clamp the locking rope. The distance between the end of the protrusion and the circumferential side closest to the suspension shaft 3 should be no less than 1 / 2 of the locking rope diameter to ensure that the protrusion can play the role of clamping the locking rope.

[0036] A gap is set between one end of the hanging shaft 3 to which the second fixing plate 5 is fixed and the box wall 6. The purpose is to isolate the hanging shaft 3 from the box wall 6 and prevent the deformation of the hanging shaft 3 and the reinforcing iron 7 from being transmitted to the box wall 6.

[0037] Connection process:

[0038] Placement holes are opened at corresponding positions of the first fixed plate 4 and the reinforcing iron 7, the first fixed plate 4 and the pulling plate 1 are welded to the reinforcing iron 7 of the oil tank, the hanging shaft 3 is welded to the first fixed plate 4 and the pulling plate 1, and then the clamping plate 2 is welded to one end of the hanging shaft 3 fixed to the pulling plate 1, and the second fixed plate 5 is welded to the other end of the hanging shaft 3; finally, the reinforcing iron 7 is welded to the box wall 6 of the oil tank.

[0039] Working process:

[0040] Embodiment 1: When the oil tank needs to be hoisted, the locking rope can be fixedly wound in the gap between the first fixed plate 4 and the second fixed plate 5 of the hanging shaft 3 in a suitable winding manner, and the other end of the locking rope is connected and wound with the hoist. After the connection, the oil tank can be hoisted; wherein, the reinforcing iron 7 is welded to the wall of the oil tank, and within the set service life, and different sizes of the hanging shaft 3 and the reinforcing iron 7 are selected according to the different qualities of the oil tanks, most of the stress is concentrated on the hanging shaft 3 and the reinforcing iron 7, and the impact on the wall 6 of the oil tank can be ignored.

[0041] Example 2: When the oil tank needs to be transported, the locking rope can be fixedly wound in the gap between the first fixed plate 4 and the second fixed plate 5 of the hanging shaft 3 in a suitable winding manner, and the locking rope can be passed through the through hole on the pull plate 1 and then tied and fixed to the carrier, so that the oil tank is firmly fixed on the carrier and can be transported.

[0042] Embodiment 3: When the fuel tank needs to be transported over a short distance and there is no need to tie a fixed knot, the fuel tank and the vehicle can be fixed, and the last rope buckle used for fixing can be placed in the protrusion of the pallet 2, and the operator can follow. After arriving at the destination, the operator can directly take out the last rope buckle from the protrusion of the pallet 2 to loosen the locking rope, and then immediately remove the locking rope wrapped around the fuel tank and the vehicle, which can reduce the knotting time of the locking rope.
