Description
Technical Field
[0001] The utility model belongs to the technical field of I-beams, and particularly relates to a lifting fixture for I-beams. Background Art
[0002] An I-beam is a long rolled profile with an I-shaped cross-section, consisting of upper and lower parallel flanges and a web connected vertically. It is named because its cross-sectional shape resembles the Chinese character "工". Its main classifications include: ordinary I-beams, light I-beams, and wide-flange I-beams. By taking advantage of the distribution of the cross-sectional moment of inertia, the I-beam has excellent bending and shear resistance in the plane of the web, but its stability perpendicular to the web is weak, so it is mainly applicable to unidirectional bending members. Its material is mostly carbon structural steel or low-alloy steel and is produced by hot rolling. With the characteristics of high strength, light weight, easy processing and installation, the I-beam is widely used in load-bearing scenarios such as building structure beams and columns, industrial factories, bridge supports, vehicle chassis, and machinery manufacturing.
[0003] During the use of the I-beam, it needs to be transported, and a fixture specific to the shape of the I-beam is required. For example, an I-beam lifting fixture with the publication number CN221587868U. This technical solution can be adjusted within a certain range, can adapt to different models of I-beams, save costs, and improve work efficiency. However, this technical solution alone cannot lift the I-beam. Multiple such technical solutions need to be used in cooperation to complete the lifting action. However, during the use of multiple such technical solutions, the problem of lateral movement occurs. If only one device is used to lift multiple such lifting fixtures, it will cause multiple such lifting fixtures to gather together, and finally still lift the I-beam at one point, unable to ensure the balance of the lifting, which is relatively dangerous.

The present invention provides a technical solution: a hoisting clamp for an I-beam, comprising: an I-beam body 1, the external of the I-beam body 1 being movably mounted on two mounting structures, the internal of the two mounting structures being movably mounted on two sets of mounting clamping structures, the upper walls of the two mounting structures being mounted on hoisting structures, and the inner walls of the two mounting structures being mounted on mutually abutting structures; the two mounting structures include: a mounting frame 2, six mounting shafts 3, and six mounting wheels 4; the six mounting shafts 3 are respectively mounted on the inner wall of the mounting frame 2, the six mounting wheels 4 are respectively movably mounted on the external of the mounting shafts 3, and the six mounting wheels 4 are respectively movably attached to the lower wall of the top of the I-beam body 1; the upper wall of the mounting frame 2 is provided with eight sliding holes, and the mounting wheels 4 are provided with flanges.
[0019] As a preferred embodiment, the four sets of mounting clamping structures further include: two slide rods 5, a clamping pulley frame 6, a clamping fixing wheel 7, a clamping top plate 8, and two clamping springs 9; the two slide rods 5 are respectively movably installed in the sliding holes of the mounting frame 2, the clamping pulley frame 6 is installed on the lower wall of the two slide rods 5, the clamping fixing wheel 7 is movably installed on the outside of the clamping pulley frame 6, the clamping top plate 8 is installed on the upper wall of the two slide rods 5, the two clamping springs 9 are installed between the clamping top plate 8 and the mounting frame 2, and the two clamping springs 9 are respectively located on the outside of the slide rods 5, and the clamping fixing wheel 7 is provided with a flange.
[0020] As a preferred option, the two sets of hoisting structures further include: a hoisting frame 10, a hoisting movable sleeve 11, and hoisting ropes 12; the hoisting frame 10 is installed on the upper wall of the hanging frame 2, the hoisting movable sleeve 11 is movably installed on the outside of the hoisting frame 10, one end of the hoisting rope 12 is fixedly installed on the upper wall of the hoisting movable sleeve 11, the upper ends of the two hoisting ropes 12 are fixed by rope connecting buckles, and the upper ends of the two hoisting ropes 12 are equipped with main ropes 15.
[0021] As a preferred embodiment, the two sets of abutment structures further include: abutment mother pipe 13 and abutment daughter pipe 14; the abutment mother pipe 13 is installed on the inner wall of the mounting frame 2, the abutment daughter pipe 14 is movably installed on the inner wall of the abutment mother pipe 13, the side walls of the abutment mother pipe 13 and the abutment daughter pipe 14 are provided with several holes, and the abutment mother pipe 13 and the abutment daughter pipe 14 are relatively fixed to each other by bolts and nuts, and abutment plates 16 are installed on the inner walls of the two abutment daughter pipes 14.
[0022] Working principle: When using this device, first connect the main rope 15 to existing hoisting equipment, such as a crane. Then, the operator needs to adjust the relative positions between the two sets of mutual abutment mother pipes 13 and mutual abutment daughter pipes 14 to determine the distance between the two mounting frames 2. The operator needs to measure the total length of the I-beam body 1. The distance between the two mounting frames 2 is one-quarter of the total length of the I-beam body 1. Half of the distance between the two mounting frames 2 is the total length of the mutual abutment mother pipe 13 and mutual abutment daughter pipe 14. After adjusting the relative distance between the mutual abutment mother pipe 13 and mutual abutment daughter pipe 14, bolts and nuts are inserted into the holes of the mutual abutment mother pipe 13 and mutual abutment daughter pipe 14 to complete the relative fixation of the mutual abutment mother pipe 13 and mutual abutment daughter pipe 14.
[0023] When hoisting the I-beam body 1, the operator needs to ensure that the six mounting wheels 4 are against the lower wall surface of the upper end of the I-beam body 1, and that the clamping and fixing wheels 7 are against the upper wall surface of the I-beam body 1. At this time, the two sliding rods 5 slide upward in the sliding holes of the mounting frame 2, and the two clamping springs 9 are in a stretched state. The two clamping springs 9 will also have a tendency to contract, forming a force that causes the clamping pulley frame 6 to drive the clamping and fixing wheels 7 to move towards the I-beam body 1, thus clamping the upper end of the I-beam body 1 with the clamping and fixing wheels 7 and the mounting wheels 4. Next, the operator makes the two sets of abutment plates 16 contact each other and moves the position of the abutment plates 16 so that the abutment plates 16 are as centrally located as possible. This completes the installation of the device.
[0024] Next, the operator pulls the main rope 15 upward using the hoisting equipment. The main rope 15 drives the two hoisting ropes 12 to pull upward, which in turn pulls the hoisting frame 10 upward through the two hoisting movable sleeves 11. The hoisting frame 10 drives the hanging frame 2 to move upward. By clamping the I-beam body 1, the I-beam body 1 is moved upward, thus completing the movement of the I-beam body 1.
