Description

Technical Field

[0002] The steel structure construction hanger of the highway toll station is usually used to support and suspend building materials and equipment for construction work. The highway toll station needs to use the construction hanger to hoist the steel structure during construction. The existing steel structure bracket is mainly used for beams and columns on the building. Most of them adopt the "I" structure, that is, two horizontal plates are used as the upper and lower main reinforcements, and the middle longitudinal vertical plate is used as the supporting web, so as to connect the steel structures to form a general frame. In the process of hoisting the I-beam, the I-beam clamp is often used to clamp the I-beam. The I-beam clamp can clamp the I-beam tightly to ensure its stability and safety during the construction process.

[0003] However, during the use of existing I-beam clamps, due to different specifications of I-beams, when clamping an I-beam with a larger width, the contact area between the clamp jaws and the I-beam is reduced, thereby reducing the stability of the I-beam clamp in clamping the I-beam, making it prone to shaking, and reducing the safety during the lifting construction process.

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.

[0028] Example 1: Please refer to Figure 1-Figure 7 The cam 2 is a kind of steel structure construction hanger for a high-speed toll station shown in the figure, and the number of each cam 2 is two, and each cam 2 is symmetrically distributed in the front and back, and the two cam plates 2 in the same group are fixedly assembled, and the cam plates 2 are provided with a clamping opening, and the clamping opening is used to clamp the I-beam, and the tops of the two cam plates 2 are hingedly provided with a rotating shaft 15, and a limiting column 1 is rotatably assembled between each cam plate 2, and the two limiting columns 1 are symmetrically distributed, and a threaded rod 3 is inserted into the inside of the two limiting columns 1, one of the limiting columns 1 is threadedly sleeved on the outside of the threaded rod 3, and the other limiting column 1 and the threaded rod 3 are rotatably assembled, and a handle 4 is fixedly provided on the end of the threaded rod 3 away from the limiting column 1. The clamping opening provided on the cam plate 2 plays a role in clamping and limiting the I-beam, and at the same time, the two cam plates 2 are fixed by using the limiting column 1 and the threaded rod 3.

[0029] It also includes: a fastening unit to prevent the clamping plate 2 from shaking when clamping the I-beam, and the fastening unit is located at the bottom of the clamp; a trigger unit for driving the fastening unit, and the trigger unit is located inside the two sets of clamping plates 2 and on the top of the rotating shaft 15.

[0030] The fastening unit includes two first piston sleeves 5 fixedly arranged inside each group of clamping plates 2. The first piston sleeves 5 are located at the bottom of the clamping mouth of the clamping plate 2, and the axis of the first piston sleeve 5 is inclined toward the rotating shaft 15. The position of the first piston sleeve 5 satisfies the stability of the fastening unit to the I-beam, and at the same time, the first piston sleeve 5 does not interfere with the components inside each group of clamping plates 2.

[0031] The first piston sleeve 5 is internally slidably equipped with a first piston block 7, and a first piston rod 8 is fixedly provided at one end of the first piston block 7 close to the rotating shaft 15, and the first piston rod 8 slides through the first piston sleeve 5. A spring 9 is fixedly equipped at one end of the first piston block 7 close to the first piston rod 8 and inside the first piston sleeve 5, and the spring 9 is distributed on the outside of the first piston rod 8. The first piston block 7 drives the first piston rod 8 to slide, and the use of the spring 9 plays a stabilizing role in the first piston rod 8 clamping the limiting I-beam.

[0032] The trigger unit includes a second piston sleeve 11 fixedly mounted on the outer surface of a rotating shaft 15, a second piston block 13 is slidably mounted inside the second piston sleeve 11, a second piston rod 12 is fixedly mounted on one end of the second piston block 13 away from the rotating shaft 15, and the second piston rod 12 slides through the second piston sleeve 11, a lifting ring is fixedly mounted on one end of the second piston rod 12 away from the second piston block 13, two circular holes are provided on the outer surface of the second piston sleeve 11 away from the bottom, and hydraulic pipes 6 are fixedly mounted on the two circular holes and the bottoms of the two first piston sleeves 5 respectively, the lifting ring facilitates the lifting of the clamp plate 2 and the I-beam by the lifting rope on the lifting machine, and the hydraulic pipe 6 causes the pressure liquid to flow from the second piston sleeve 11 into the first piston sleeve 5.

[0033] The axis line of the second piston sleeve 11 is the perpendicular bisector of the axis line of the rotating shaft 15, and the axis line of the second piston sleeve 11 is perpendicular to the horizontal plane. The position of the second piston sleeve 11 makes the I-beam evenly stressed during the lifting process. At the same time, the second piston sleeve 11 is located in the middle of the same group of clamping plates 2, which makes the lifting of the clamping plates 2 and the I-beam more stable.

[0034] The hydraulic pipe 6 is made of a flexible material and can be bent and folded, so that the hydraulic pipe 6 will not interfere with the components inside each set of clamp plates 2.

[0035] The interior of the hydraulic pipe 6 , the interior of the first piston sleeve 5 and the interior of the second piston sleeve 11 are filled with pressure liquid, and the flow of the pressure liquid causes the first piston block 7 and the first piston rod 8 to slide inside the first piston sleeve 5 .

[0036] The volume of the second piston sleeve 11 is twice that of the first piston sleeve 5 , so that the pressure fluid can completely push out the first piston block 7 .

[0037] Working principle:

[0038] The staff first adjusts the angle between the two sets of clamping plates 2 so that the clamping mouth of the clamping plates 2 is aligned with the I-beam. Secondly, the staff turns the handle 4 to rotate the threaded rod 3, and the two sets of clamping plates 2 are hinged and rotated until the I-beam is completely clamped. Then the lifting rope of the hoisting machine is installed on the lifting ring at the top of the second piston rod 12. The operator starts the hoisting machine to make the second piston rod 12 rise. Under the action of the gravity of the I-beam and the I-beam clamp itself, the second piston rod 12 slides inside the second piston sleeve 11. The interiors of the second piston sleeve 11, the hydraulic pipe 6 and the first piston sleeve 5 are interconnected and filled with pressure liquid, so that during the upward sliding of the second piston rod 12, the pressure liquid flows from the interior of the second piston sleeve 11 to the interior of the first piston sleeve 5. The sealing rings at both ends of the hydraulic pipe 6 prevent the leakage of the pressure liquid. Due to the entry of the pressure liquid into the interior of the first piston sleeve 5, the first piston block 7 and the first piston rod 8 slide obliquely upward as a whole. The first piston rod 8 is against the I-beam and plays a tightening role in the clamping of the clamping plate 2.

[0039] Example 2: Please refer to Figure 6 In the figure, the end of the first piston rod 8 away from the first piston block 7 is elastically rotated and equipped with a pressure foot block 10 through a coil spring and a latch, and the maximum rotation angle between the first piston rod 8 and the pressure foot block 10 is ninety degrees. The pressure foot block 10 increases the area of ​​the first piston rod 8 clamping the I-beam, thereby making the process of clamping and lifting the I-beam more stable.

[0040] A silicone rubber gasket is fixedly provided on the outer surface of the presser foot block 10 facing the I-beam, which increases the friction coefficient of the presser foot block 10 facing the outer surface of the I-beam and avoids wear between the presser foot block 10 and the I-beam.

[0041] In this embodiment: the presser foot block 10 elastically rotatably assembled with the first piston rod 8 by the coil spring and the latch slides obliquely upward together with the first piston rod 8. When the presser foot block 10 abuts against the I-beam, the angle between the plane of the presser foot block 10 facing the I-beam and the I-beam gradually decreases until the two are completely in contact. Due to the action of the coil spring and the latch, the rotation of the presser foot block 10 has a certain torque and angle, which avoids the situation where the presser foot block 10 rotates in a stationary state, and the situation where the presser foot block 10 rotates too much, resulting in incomplete or no contact between the presser foot block 10 and the I-beam. The silicone rubber gasket fixedly arranged on the plane where the presser foot block 10 contacts the I-beam makes the clamping of the presser foot block 10 to the I-beam more stable.

[0042] Example 3: Please refer to Figure 6 In the figure, at least one arc-shaped ridge 14 is fixedly provided on the outer surface of the first piston rod 8, and the arc-shaped ridge 14 slides through the first piston sleeve 5.

[0043] In this embodiment: the arc-shaped convex strip 14 fixedly arranged on the outer surface of the first piston rod 8 guides the first piston rod 8 to slide inside the first piston sleeve 5. At the same time, the arc-shaped convex strip 14 and the first piston rod 8 slide together through the first piston sleeve 5, which limits the sliding of the first piston rod 8 and prevents the first piston rod 8 from rotating itself during the sliding process.
