Description

Technical Field

[0001] The utility model belongs to the technical direction of hydraulic correction pliers, and specifically relates to a hydraulic correction pliers used for the connection of a steel cage sleeve. Background Art

[0002] In pile foundation engineering, when connecting the straight thread sleeve of the steel cage, the straight thread sleeve often cannot be turned because the steel cage is deformed during placement or transportation, resulting in the wrong angle of the steel bar. In the face of this situation, the traditional way is often to add three to four people to turn a hydraulic clamp or solve it by welding the steel bar. The first method will cause the internal steel bar head to slip even if it is turned. The second method is time-consuming and labor-intensive, and is not environmentally friendly. This phenomenon has become a problem that needs to be solved urgently by personnel in this field. Therefore, a hydraulic correction clamp for the connection of the steel cage sleeve is designed, which can smoothly connect the straight thread sleeve without damaging the thread, so as to achieve the purpose of correcting the steel bar docking angle, saving time and effort and being green and environmentally friendly.

[0016] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0017] See also Figure 1-3 The utility model provides a technical solution: a hydraulic correction pliers used for the connection of a steel cage sleeve, comprising a hydraulic driving cylinder 1, a fixed handle 2 fixedly connected to the right side of the hydraulic driving cylinder 1, a pressing handle 3 rotatably connected to the top of the hydraulic driving cylinder 1, and a handle sleeve 4 fixed on the right end of the fixed handle 2 and the pressing handle 3. By setting the handle sleeve 4, sliding can be avoided when using the hydraulic correction pliers, thereby improving the safety and comfort of use.

[0018] The left end of the hydraulic drive cylinder 1 is fixedly connected to a connecting block 5, the lower end of the connecting block 5 is fixedly connected to a fixed jaw 6, the upper end of the connecting block 5 is provided with a movable jaw 7, a slide groove 8 is opened on the connecting block 5, and a slider is fixedly connected to the bottom of the movable jaw 7. The slider is arranged in the slide groove 8 so that the movable jaw 7 is slidably connected to the connecting block 5. The slider inside the connecting block 5 and the bottom of the movable jaw 7 are connected with the oil circuit inside the hydraulic drive cylinder 1. An oil circuit switch is arranged on the hydraulic drive cylinder 1. Tighten the oil circuit switch and press the pressing handle 3 so that the oil in the connecting block 5 enters the hydraulic drive cylinder 1, driving the movable jaw 7 to slide down, so that the movable jaw 7 and the fixed jaw 6 clamp the steel bar. By arranging the movable jaw 7 and the fixed jaw 6 to be staggered up and down, the upper steel bar joint and the lower steel bar joint of the connection can be fixed at the same time, and then the hydraulic correction pliers are twisted manually, that is, the upper steel bar joint and the lower steel bar joint are simultaneously forced, so as to achieve a correction effect.

[0019] A tooth opening 9 is provided on one side opposite to the fixed jaw 6 and the movable jaw 7. The tooth opening 9 is semicircular and conforms to the diameter of the steel bar.

[0020] The fixed jaws 6 and the movable jaws 7 are high-strength, precision-cast jaws, and are chrome-plated on the surface, so they are firm and durable.

[0021] A protective pad 10 is fixedly connected to the tooth opening 9 of the fixed jaw 6 and the movable jaw 7. The shape of the protective pad 10 matches the shape of the tooth opening 9. The protective pad 10 is made of solution-polymerized styrene-butadiene rubber (SSBR), which has better rolling resistance and anti-slip performance than emulsion-polymerized styrene-butadiene rubber. The protective pad 10 made of solution-polymerized styrene-butadiene rubber is green and environmentally friendly, and can also protect the steel bar head thread from damage, thereby ensuring the integrity of the steel bar head thread.

[0022] Working principle: the fixed jaw 6 of the hydraulic correcting pliers corresponds to the lower steel bar joint at the connection, the movable jaw 7 corresponds to the upper steel bar joint, the oil circuit switch is tightened, and the pressing handle 3 is pressed to allow the oil in the connecting block 5 to enter the hydraulic drive cylinder 1, driving the movable jaw 7 to slide down, so that the movable jaw 7 and the fixed jaw 6 clamp the steel bar, and by arranging the movable jaw 7 and the fixed jaw 6 to be staggered up and down and fixing the connecting protective pad 10 at the tooth mouth 9, the upper and lower steel bar joints at the connection can be fixed at the same time and the steel bar head thread slippage at the fixed position can be prevented, and then the hydraulic correcting pliers are twisted manually, that is, force is applied to the upper and lower steel bar joints at the same time, so as to achieve a corrective effect.
