Technical Field

[0001] The utility model relates to the technical field of steel structure processing, in particular to a supporting device which is easy to disassemble. Background Art

[0002] As one of the main types of building structures, steel structures are composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. They have the advantages of high strength, light weight and fast construction speed. Therefore, they are widely used in the construction field. In the process of steel structure processing, welds, bolts or rivets are commonly used connection methods. These connection works often require support devices to support the steel structure to ensure the accuracy and stability of the connection.

[0003] However, traditional support devices have certain design deficiencies. For example, most traditional support devices are integral structures with bulky volumes that are not easy to disassemble and assemble. Especially when supporting and installing simple cross plates, beams, columns or steel pipes, once the installation is completed, the disassembly process becomes particularly complicated and cumbersome, which not only increases the labor intensity of the operators, but also seriously affects the work efficiency. For this reason, we propose a support device that is easy to disassemble. Utility Model Content

[0017] like Figures 1 to 3As shown, the utility model discloses a support device that is easy to disassemble. The technical solution adopted is that it includes a support column 1 and a base 2. The base 2 is fixedly installed at the bottom of the support column 1. The base 2 is a rectangular structure. The four corners of the base 2 are respectively provided with mounting holes 11. Through the arrangement of the mounting holes 11, it is convenient for the staff to respectively pass the external fixing bolts through the mounting holes 11 and connect them with the corresponding screw holes on the ground, thereby ensuring a firm connection between the base 2 and the ground. In addition, this connection method is also convenient for the staff to disassemble it. It also includes a reinforcing plate 10. The reinforcing plates 10 are provided with at least three. The reinforcing plates 10 are a right-angled triangle structure. The reinforcing plates 10 are respectively arranged in a circular array at equal distances at the outer bottom of the support column 1, and the right-angle ends of the reinforcing plates 10 are connected. The adjacent two sides are fixedly connected with the support column 1 and the base 2 respectively. The support column 1 is a hollow structure. A lifting support rod 9 is arranged inside the support column 1. The lifting support rod 9 is a threaded rod. Four sliders 7 arranged in a circular array at equal distances at the bottom of the lifting support rod 9 are respectively slidably connected with the slide groove 8 arranged on the inner side of the support column 1. A support assembly 3 is arranged at the top of the lifting support rod 9. The support assembly 3 consists of a top frame 31 and a support block 32. A second bearing 12 is arranged at the bottom center of the top frame 31. The top frame 31 is rotatably installed on the top of the lifting support rod 9 through the second bearing 12. After the top frame 31 is moved to a suitable height by the lifting support rod 9, since the top frame 31 is rotatably connected with the lifting support rod 9 through the second bearing 12, the top frame 31 can be adjusted in the horizontal direction The angle of the top frame 31 can be adjusted to meet more support requirements. Support blocks 32 are welded on the left and right ends of the top of the top frame 31, and the support block 32 is a "U"-shaped structure. The "arc-shaped" structure on the top of the support block 32 can support the steel pipe structure. A bearing seat 4 is provided on the top of the outer side of the support column 1. A driving unit 5 that can drive the lifting support rod 9 to move up and down is rotatably installed on the inner side of the bearing seat 4. The driving unit 5 consists of a sleeve 51, a first bearing 52, a connecting rod 53 and an annular connecting plate 54. The sleeve 51 is set on the outer side of the bearing seat 4. The screw hole set in the center of the top of the sleeve 51 is threadedly connected to the outer side of the lifting support rod 9. The first bearing 52 fixedly installed in the middle part of the inner side of the sleeve 51 is rotatably installed on the bearing seat 4. On the inner side, five connecting rods 53 are arranged in an equidistant circular array at the bottom of the sleeve 51, and an annular connecting plate 54 is fixedly installed at the bottom of the connecting rod 53. The annular connecting plate 54 is rotatably installed in a connecting seat 6 arranged in the middle of the outer side of the support column 1. Five push rods 55 are arranged in an equidistant circular array in the middle of the outer side of the annular connecting plate 54. By pushing the push rods 55 and pulling the connecting rods 53 in the same side direction, the annular connecting plate 54 rotates in the connecting seat 6. At the same time, the first bearing 52 in the sleeve 51 rotates inside the bearing seat 4. Since the screw hole on the sleeve 51 is threadedly connected to the lifting support rod 9, the slider 7 at the bottom of the lifting support rod 9 slides downward along the slide groove 8, and the lifting support rod 9 is retracted into the support column 1.The support assembly 3 can be separated from the external simple horizontal plate or beam column, thereby completing the disassembly.

[0018] The working principle of the utility model is as follows: when in use, the base 2 is first placed stably at the desired supporting position, and then the push rod 55 is pushed and the connecting rod 53 is pulled in the same side direction to rotate the annular connecting plate 54 in the connecting seat 6. At the same time, the first bearing 52 in the sleeve 51 rotates inside the bearing seat 4. Since the screw hole on the sleeve 51 is threadedly connected with the lifting support rod 9, the slider 7 at the bottom of the lifting support rod 9 slides upward along the slide groove 8 until the supporting assembly 3 at the top of the lifting support rod 9 supports the external simple horizontal plate or the bottom of the beam column. In addition, the staff can also connect the external fixing bolts through the installation holes 11 and the corresponding screw holes on the ground to ensure a firm connection between the base 2 and the ground; when disassembling the external simple cross plate and beam support after installation, by pushing the push rod 55 in the opposite direction and pulling the connecting rod 53 in the same direction, the lifting support rod 9 is retracted into the support column 1, and the support assembly 3 and the external simple cross plate or beam column can be separated. Then, the external fixing bolts fixed between the base 2 and the ground are removed to complete the disassembly operation of the device.
