Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting technology, and in particular to a square tube hoisting device. Background Technology
[0002] Square tubes are hollow metal tubes with a square or rectangular cross-section. Their core features are "hollow structure and regular quadrilateral cross-section". Through combinations of different materials, processes and specifications, they can be adapted to diverse scenarios from building support to industrial equipment. They are one of the basic metal profiles in modern industry and infrastructure.
[0003] In actual production, gantry cranes or hoisting vehicles are used to lift square tubes. When lifting bundles of square tubes of the same size, simply align the hook with the center of the tube; this is relatively easy. However, in actual processing, hoisting vehicles are used to transport bundles of raw square tubes of varying lengths to the processing workshop. The processing workshop then cuts the tubes to different lengths according to customer requirements. During lifting, the different lengths of square tubes have different centers of gravity, and in windy conditions, they can sway violently, easily causing the tubes to tilt. Shorter tubes are more likely to fall and injure workers. Utility Model Content

[0041] The following is combined with Figure 1-6 The square tube hoisting device involved in this utility model will be further explained and described.
[0042] A hoisting device for square tubes 5 includes a crossbeam 1, a hoisting and binding assembly 2, two telescopic assemblies 3, and two clamping assemblies 4. The crossbeam 1 has a first side 11 and a second side 12 facing each other. A hook 13 for connecting to a hoisting vehicle is fixedly connected to the first side 11. The hoisting and binding assembly 2 includes a hook 21 and a binding strap 22. The hook 21 is fixedly connected to the second side 12 and can hook the binding strap 22. The binding strap 22 is used to bind several square tubes 5. The two telescopic assemblies 3 are respectively fixedly connected to the hoisting and binding assemblies 4. At the two opposite ends of the crossbeam 1, the telescopic component 3 extends in a direction parallel to the extension direction of the crossbeam 1; two clamping components 4 are fixedly connected to the two telescopic components 3 in a one-to-one correspondence, and the two clamping components 4 are arranged perpendicular to the extension direction of the crossbeam 1 and are opposite to each other, and each clamping component 4 can move closer or further away from each other under the telescopic drive of each telescopic component 3; each clamping component 4 has a flexible layer 44 on the side opposite to the other, so as to flexibly clamp the square tube 5 and match the end shape of each square tube 5.
[0043] In this embodiment, multiple square tubes 5 can be lifted from the middle by the crossbeam 1 and the lifting assembly 2. Then, the telescopic movement of the two telescopic assemblies 3 causes the two clamping assemblies 4 to clamp the ends of each square tube 5 inward. The position of the square tube 5 can be adjusted to make the square tube 5 centered. Furthermore, the flexible layer 44 on the clamping assembly 4 can better match the end formation of the square tube 5, achieving a better lifting and fixing effect, thus solving the technical problem that square tubes of different lengths are prone to falling when being lifted.
[0044] Specifically, the flexible layer 44 in this embodiment can be a block or sheet made of materials such as sponge, rubber, or silicone. Rubber is preferred because it has good wear resistance and can prevent the square tube 5 from being punctured. Of course, it can also be other existing materials such as polytetrafluoroethylene, thermoplastic rubber, thermoplastic polyurethane, or polyurethane.
[0045] In addition, the telescopic component 3 can be a hydraulic cylinder or an electric push rod, etc.
[0046] In one embodiment of a square tube 5 hoisting device, the clamping assembly 4 includes an upper plate 41, a lower plate 42, a middle section 43, and a flexible layer 44. One end of the middle section 43 is fixedly connected to the upper plate 41, and the other end is fixedly connected to the lower plate 42. The two sides of the flexible layer 44 are fixedly connected to the upper plate 41 and the lower plate 42, respectively, and the two ends of the flexible layer 44 are fixedly connected to the middle section 43, so that a closed space 45 can be formed by the upper plate 41, the lower plate 42, the middle section 43, and the flexible layer 44. The hoisting device also includes two magnetic field generating devices and two magnetorheological fluids. Each magnetorheological fluid is contained in each of the closed spaces 45. Each magnetic field generating device is installed in each of the clamping assemblies 4. The magnetic field generating device is used to apply a magnetic field to the magnetorheological fluid after being energized.
[0047] In this embodiment, the upper plate 41, lower plate 42, middle plate 43, and flexible layer 44 enclose a sealed space 45, which is filled with magnetorheological fluid. Magnetorheological fluid is a solid-like substance that has fluid properties in the absence of a magnetic field and a certain strength in the presence of a magnetic field. By setting a magnetic field generating device to apply a magnetic field to the magnetorheological fluid after being energized, the magnetorheological fluid can undergo a state transformation. Thus, after multiple square tubes 5 are tied up and lifted by the hoisting assembly 2 and the telescopic assembly 3 is activated to clamp the two clamping assemblies 4 onto the square tubes 5, the operator can activate the magnetic field generating device to change the state of the magnetorheological fluid in the sealed space 45, thereby achieving a better clamping stability effect.
[0048] Specifically, the magnetic field generating device can be an existing one, including an excitation power supply and a magnetizing mechanism. By energizing the magnetizing mechanism with the excitation power supply, various types of magnetic fields such as DC magnetic field, alternating magnetic field, and pulsed magnetic field can be generated. The magnetizing mechanism includes coils such as solenoids and Helmholtz coils, weak magnetic fields, or electromagnets.
[0049] In one embodiment of a square tube 5 hoisting device, the clamping assembly 4 further includes a connecting box 46, which is fixedly installed on the side of the upper plate 41 away from the lower plate 42, and the connecting box 46 is connected to the sealed space 45 through a pipe passing through the upper plate 41.
[0050] In this embodiment, by setting up a connecting box 46, when the square tube 5 contacts the flexible layer 44 and presses against the sealed space 45, the magnetorheological fluid in the sealed space 45 can flow into the connecting box 46 after being subjected to pressure.
[0051] Preferably, a pump can be added after the connecting box 46 to circulate the magnetorheological fluid and prevent sedimentation.
[0052] In one embodiment of a square tube 5 hoisting device, the clamping assembly 4 further includes an elastic element 47 and a fixing plate 48. One end of the fixing plate 48 is fixedly connected to the upper plate 41, and the other end is fixedly connected to the lower plate 42. The fixing plate 48 is located on the side of the middle 43 away from the flexible layer 44. One end of the elastic element 47 is fixedly connected to the fixing plate 48, and the other end is fixedly connected to the middle 43.
[0053] In this embodiment, the elastic element 47 and the fixing plate 48 are used to set the middle 43 in the middle position. In this way, the elastic element 47 can give the middle 43 an elastic force, which can effectively prevent the middle 43 from deforming.
[0054] In one embodiment of a square tube 5 hoisting device, the number of elastic elements 47 in a clamping assembly 4 is multiple, and each elastic element 47 is evenly distributed.
[0055] In this embodiment, by setting multiple elastic elements 47, a better stabilizing effect can be achieved. Specifically, the arrangement can be a variety of uniform distribution methods such as linear, circular, or matrix.
[0056] In one embodiment of a specific pipe 5 hoisting device, the number of elastic elements 47 in one clamping assembly 4 is two.
[0057] In one embodiment of a square tube 5 hoisting device, the crossbeam 1 has a receiving space. The hoisting device also includes a slider 61, a slide rail 62, a hammer 63, two mounting plates 64, and two viscous dampers 65. The two mounting plates 64 are fixedly connected to the inner wall of the crossbeam 1 at a relative interval. The two viscous dampers 65 are correspondingly inserted through each mounting plate 64 and fixedly connected to each mounting plate 64. The two ends of the slide rail 62 are respectively fixedly connected to the telescopic ends of the viscous dampers 65. The slider 61 is slidably connected to the slide rail 62, and the hammer 63 is rotatably connected to the slider 61.
[0058] In this embodiment, when the crossbeam 1 shakes or swings, the hammer 63 in the receiving space will also shake or swing. The sliding or swinging of the hammer 63 consumes energy and will also drive the slider 61 to slide. The sliding of the slider 61 will then transmit the force to the viscous dampers 65 on both sides, and the viscous dampers 65 will consume this part of the energy, thereby improving the stability of the overall device.
[0059] In one embodiment of a square tube 5 hoisting device, the hoisting device further includes two guide posts 66, the two ends of which are fixedly connected to the mounting plate 64 and are arranged along the extension direction of the slide rail 62, and both guide posts 66 pass through the slider 61.
[0060] In this embodiment, by setting two guide posts 66, the movement of the slider 61 can be guided more smoothly, and the slider 61 can be prevented from slipping.
[0061] In one embodiment of a square tube 5 hoisting device, the initial position of the hammer 63 is on the same longitudinal line as the hoisting assembly 2.
[0062] In this embodiment, both the hammer 63 and the pendulum assembly are located in the middle of the crossbeam 1, which can balance the center of gravity of the crossbeam 1.
[0063] In one embodiment of a square tube 5 hoisting device, the hook 13 includes a hook unit 131 and multiple strands of hoisting rope 132, with one end of each strand of hoisting rope 132 fixedly connected to the hook unit 131 and the other end fixedly connected to the body of the crossbeam 1.
[0064] In the previous embodiment, the hook 13 could be a hook directly integrally formed on the crossbeam 1. However, in this embodiment, the hook 13 is composed of a hook unit 131 and a multi-strand suspension rope 132. By setting the multi-strand suspension rope 132, the entire crossbeam 1 can be lifted more effectively, thereby achieving a better stability effect.
[0065] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0066] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
