Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mobile tank, in particular to a liquid tank mobile lifting positioning tool. BACKGROUND

[0002] The storage tank is used to store acid, alkali, alcohol, gas, liquid and other refined chemical substances. The storage tank is generally made of polyethylene, polypropylene, glass fiber reinforced plastic, ceramic, rubber and stainless steel, etc. according to different materials.

[0003] The storage tank is mostly large in size and is used to store a large amount of storage material. In this case, the storage tank is heavy and difficult to move and transport. It is very inconvenient to use manual batch delivery, which greatly reduces the work efficiency. The current market storage tank has a single function and cannot move the tank body filled with liquid material. In addition, when the material is input and output, the tank body inlet and outlet are misaligned, which is not convenient for filling and discharging the material.

[0004] The prior art discloses (announces) a precise positioning assembly tool for large storage tank, which is mainly composed of a pin seat lifter, a V seat lifter and a supporting roller frame arranged on the base assembly. The V seat, the pin seat and the walking mechanism are reasonably combined to move on the base to realize the precise and rapid assembly of the tank body, the V seat and the pin seat. The assembly becomes a V seat lifter and a pin seat lifter, which realizes positioning by using hydraulic control lifting. The defect is that the bottom lifting adopts a scissors support type lifting mechanism. Although the lifting mechanism can realize the lifting of the storage tank, it actually adopts the principle of scissors lifting table. As can be understood, the supporting distance of the bottom will gradually decrease as the lifting table rises, so that the lifting mechanism of the upper part becomes narrow. This reduces the safety and stability. Secondly, the overall weight is supported by the oil cylinder. If the hydraulic oil leakage problem occurs, the storage tank will quickly fall, which has a large safety hazard.

Once the steel wire rope 4 is broken, the pull rod 12 is pulled back to the starting end of the stroke by the tension spring 13, then as shown in Figure 6 , the clamping block 14 is immediately controlled to rotate through the connecting rod 15 to make the ratchet block 19 clamped into the ratchet bar 18, so as to support the lifting frame 2; this structure well overcomes the risk of falling of the liquid tank, improves the safety performance of the equipment, and has simple structure, high efficiency and high safety performance.
