Description

Technical Field

[0001] The utility model relates to the technical field of a hoisting device for installing an I-beam used for fish pond installation, in particular to a hoisting device for installing an I-beam used for fish pond installation. Background Art

[0002] I-beams, also known as steel beams, are long strips of steel with an I-shaped cross-section. I-beams are divided into ordinary I-beams and light I-beams. When I-beams are hoisted, they are bound in advance with straps or chains, and then lifted with a crane to raise the I-beam to the specified position.

[0003] Since the existing I-beam installation lifting devices used for fish pond installation mostly use two-point force lifting to position the I-beam, the contact area between the straps or chains and the surface of the I-beam is too small. If the force point is not centered, the I-beam may slide easily due to the shift of the center of gravity after lifting, which poses certain safety hazards and cannot be well installed. In addition, since it is difficult to control the length of the straps or chains on the upper end of the I-beam, the I-beam may tilt easily in the air, which has certain adverse effects on people's use. In order to solve the shortcomings of the prior art, we propose a lifting device for I-beam installation for fish pond installation. Utility Model Content

[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. In the utility model, by setting the first bidirectional screw and the movable frame and other structures, the distance between the two groups of second fixing frames can be adjusted according to the size of the I-beam, so that the two groups of second fixing frames can limit and fix the I-beams of different sizes. At the same time, the distance between the two groups of movable frames can be adjusted according to the length of the I-beam, so that the four groups of second fixing frames can be fixed at the port position of the I-beam, thereby increasing the stability of the I-beam during hoisting.

[0015] 2. In the utility model, the structure such as the cable rack and the transmission belt is provided to solve the problem that when the lifting assembly is in use, one end of a steel wire rope is usually connected to the lifting hook, and the other end is wrapped and fixed to the outer surface of the object to be moved. However, in order to ensure that the steel wire rope can be connected to the lifting hook, the length of the steel wire rope is usually relatively long, and there is a certain shaking after lifting. Moreover, when the steel wire rope is wrapped at two or more positions, there is usually a certain difference in the winding length of the steel wire rope, which leads to a certain tilt when the object is lifted. The tilted object may fall off due to an accident, posing a certain safety hazard. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4 As shown, a lifting device for installing an I-beam for fish pond installation, a first bidirectional screw 3 and a movable frame 5 are threadedly connected, a second bidirectional screw 8 and a second fixed frame 6 are threadedly connected, the shape of the second fixed frame 6 is adapted to the shape of the I-beam, a handle 7 and the second bidirectional screw 8 are welded, a rotation groove is provided between the first bidirectional screw 3 and the first fixed frame 1, and the first bidirectional screw 3 and the first fixed frame 1 are movably connected through the rotation groove.

[0023] like Figure 1-Figure 4 As shown, the transmission device 17 can be a gear, the transmission belt 15 can be a transmission chain meshed with the gear, the transmission device 17 and the steel cable rack 16 are welded, a rotating groove is provided between the steel cable rack 16 and the mounting frame 10, and the steel cable rack 16 and the mounting frame 10 are movably connected through the rotating groove.

[0024] It should be noted that the utility model is a lifting device for installing an I-beam for fish pond installation. When in use, the user inserts the I-beam between the four groups of second fixing frames 6. According to the length of the I-beam, the first motor 2 drives the first bidirectional screw 3 to rotate, and the first bidirectional screw 3 drives the two groups of movable frames 5 to move in opposite directions at the same time, so that the two groups of movable frames 5 are located at the port position of the I-beam. The user turns the handle 7 to rotate the second bidirectional screw 8, and the two groups of second fixing frames 6 on the outer wall of the second bidirectional screw 8 change position at the same time, so that the second fixing frame 6 is tightly attached to the lower end of the I-beam, thereby completing the fixation of the I-beam.

[0025] After the I-beam is fixed and before the lifting operation begins, the second motor 14 drives the transmission 17 to rotate, and the transmission 17 drives the transmission belt 15 to drive another set of transmissions 17 to rotate, so that the two sets of transmissions 17 drive the cable rack 16 to rotate in the same direction and at the same speed, avoiding differences in the winding lengths of the lifting cables 13, that is, the cable rack 16 can complete the winding of the lifting cables 13, and bring the first fixed frame 1 close to the lower end surface of the mounting frame 10, preventing large shaking and tilting in the first fixed frame 1 during the suspension process, which increases safety hazards.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
