There are three ways to connect steel structures, namely: welding, riveting and bolting. The current usage methods are: welding is the most common application. High-strength bolt connection has developed rapidly in recent years and is used more and more. Rivet connection has been basically replaced by welding and high-strength bolt connection and is rarely used. The characteristics of rivet connection are reliable force transmission, good plasticity and toughness, easy quality inspection and assurance, and can be used for heavy structures that bear dynamic loads, but its structure is complex, steel and labor-intensive, working conditions are poor, and cost is high.

[0013] Technical effects and advantages of the present invention:

[0014] 1. The oil flows into the oil chamber of the hydraulic cylinder through the flow of the oil. When the oil fills the oil chamber of the hydraulic cylinder, the lever handle is pressed back and forth as a whole, so that the oil inside the oil tank is connected to the oil suction check valve. By pressing the lever handle back and forth, the second oil pipe, the third oil pipe and the fourth oil pipe are filled with oil. Affected by the flow of the oil, the oil is injected into the airbag clamping ring.

[0015] 2. When the lever handle is pressed, the oil in the oil tank and the oil cavity of the pump body flows into the second oil pipe, the third oil pipe and the fourth oil pipe. When the lever handle is continuously pulled upward, the oil is recovered into the oil tank due to the weight of the steel structure, and the airbag clamping ring as a whole returns to its initial state. Secondly, due to the squeezing of the heavy object, the heavy object slowly retracts into the oil cavity of the hydraulic cylinder, and the balance contact plate gradually rises and returns to its initial state, so that the equipment as a whole can be used reciprocatingly, reducing unnecessary tools.

[0016] 3. The overall expansion of the airbag clamping ring squeezes the steel component inside the steel component connection support, so that the airbag clamping ring as a whole supports the steel component. After the airbag clamping ring inside the steel component connection support completes the support, continue to reciprocate the lever handle as a whole, so that the weight inside the hydraulic cylinder oil chamber gradually falls, and the balance contact plate at the bottom of the weight supports the steel component connection support as a whole. Multiple groups of balance contact plates gradually maintain balance with the ground, and the steel component connection support as a whole reaches a horizontal state, which is convenient for the later processing and maintenance of the steel component.

By reciprocatingly pressing the lever handle 5, the interior of the second oil pipe 11, the third oil pipe 12 and the fourth oil pipe 13 are filled with oil. Under the influence of the flow of the oil, the oil is injected into the interior of the airbag clamping ring 3, and the airbag clamping ring 3 expands as a whole to squeeze the steel component inside the steel component connecting support 1, so that the airbag clamping ring 3 as a whole supports the steel component. After the airbag clamping ring 3 inside the steel component connecting support 1 completes the clamping, continue to reciprocately press the lever handle 5 as a whole, so that the weight 16 inside the hydraulic cylinder oil chamber 15 gradually falls, and the balance contact plate 17 at the bottom of the weight 16 supports the steel component connecting support 1 as a whole, reducing the gap between the steel components.

[0029] Working principle: When the equipment is in use, align the empty space at the top of the steel component connecting support 1 with one end of the steel component. After the steel component is inserted into the steel component connecting support 1, press the lever handle 5 as a whole to make the lever handle 5 move back and forth as a whole.

While the oil fills the hydraulic cylinder oil chamber 15, the lever handle 5 is continuously pressed back and forth as a whole, so that the oil in the oil tank 9 is filled with oil. The oil inside the box is connected to the oil suction check valve 8, so that the oil suction check valve 8 is connected to the oil chamber 6 of the pump body.

By reciprocatingly pressing the lever handle 5, the interior of the second oil pipe 11, the third oil pipe 12 and the fourth oil pipe 13 are filled with oil. Under the influence of the flow of the oil, the oil is injected into the interior of the airbag clamping ring 3. The airbag clamping ring 3 expands as a whole to squeeze the steel component inside the steel component connecting support 1, so that the airbag clamping ring 3 as a whole supports the steel component. After the airbag clamping ring 3 inside the steel component connecting support 1 completes the clamping, continue to reciprocate The lever handle 5 as a whole makes the hydraulic cylinder oil chamber 1 The weight 16 inside 5 gradually falls down, and the balance contact plate 17 at the bottom of the weight 16 props up the steel component connection support 1 as a whole, reducing the gap between the steel components.

At the same time, when the lever handle 5 is continuously pulled upward, the oil is recovered into the oil tank 9 under the influence of the weight of the steel structure, and the airbag clamping ring 3 is restored to its initial state as a whole. Secondly, under the influence of the squeezing of the weight, the weight 16 slowly retracts into the hydraulic cylinder oil chamber 15, and the balance contact plate 17 gradually performs a recovery movement to restore the initial state, so that the equipment as a whole can be used reciprocatingly, reducing unnecessary tools;

[0030] Secondly, when the steel components are assembled unevenly, the steel component connecting support 1 is tilted as a whole due to the weight of the steel components, and contacts the ground through multiple sets of balancing contact plates 17, so that the oil is injected into the interior of the airbag clamping ring 3. The airbag clamping ring 3 expands as a whole to squeeze the steel component inside the steel component connecting support 1, so that the airbag clamping ring 3 as a whole supports the steel component. After the airbag clamping ring 3 inside the steel component connecting support 1 completes the support, the lever handle 5 continues to be pressed back and forth as a whole, so that the weight 16 inside the hydraulic cylinder oil chamber 15 gradually falls, and the balancing contact plate 17 at the bottom of the weight 16 supports the steel component connecting support 1 as a whole. The multiple sets of balancing contact plates 17 gradually maintain balance with the ground, and the steel component connecting support 1 as a whole reaches a horizontal state, which is convenient for the later processing and maintenance of the steel component.
