Description

Technical Field

[0001] This application relates to the field of steel crane beam support technology, and in particular to a multi-column support structure for heavy-duty steel crane beams. Background Technology

[0002] A steel crane beam, an architectural term, is a beam structure that supports the operation of a bridge crane. Crane rails run along the beam, allowing the crane to travel back and forth. In the design of heavy industrial plants, the steel crane beam is a core component bearing the crane load, and the stability of its supporting structure directly affects the safety of the plant.

[0003] Currently, traditional steel crane beam support structures typically employ a single-column support structure, with the support column further supporting the crane beam. However, traditional steel crane beam support structures cannot reinforce the support column, making it prone to fatigue deformation. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a multi-column support structure for heavy-duty steel crane beams, which overcomes the shortcomings of the prior art and aims to solve the problems in the background art.

[0005] To achieve the above objectives, this application adopts the following technical solution: a multi-column support structure for a heavy-duty steel crane beam, comprising a crane beam, an upper beam fixedly connected to the bottom of the crane beam, a lower beam installed at the bottom of the upper beam, a positioning block slidably connected to the surface of the lower beam, a positioning mechanism provided on one side of the positioning block, a support mechanism provided at the bottom of the positioning block, the support mechanism comprising a mounting plate one, the mounting plate one being fixedly connected to the positioning block, four steel pipe columns fixedly connected to the bottom of the mounting plate one, the four steel pipe columns being symmetrically distributed at the bottom of the mounting plate one, a mounting plate two fixedly connected to the bottom of the steel pipe columns, a support rod fixedly connected between two adjacent steel pipe columns, a reinforcement mechanism provided on one side of the steel pipe column, and a vibration isolation mechanism provided at the bottom of the mounting plate two.

[0006] In a preferred embodiment, the positioning mechanism includes a positioning frame, which is fixedly connected to a positioning block. A positioning rod is slidably connected inside the positioning frame. A spring is provided between the positioning rod and the positioning frame. The spring is sleeved on the surface of the positioning rod. A through hole is provided on the surface of the lower beam, and the through hole is adapted to the positioning rod.

[0007] By adopting the above technical solution, the positioning rod is limited by the positioning frame, supported by a pair of springs, and then the positioning rod is inserted into the through hole on the surface of the lower beam to position the lower beam, which can better position the lower beam.

[0008] In a preferred embodiment, the reinforcement mechanism includes a damper rotatably connected to the steel pipe column. A support plate is rotatably connected to the side of the damper away from the steel pipe column. The support plate is slidably connected to the lower beam, and bolts are threaded onto the surface of the lower beam.

[0009] By adopting the above technical solution, the bolts are rotated to pass through the lower beam and enter the interior of the support plate, fixing the support plate to the surface of the lower beam. When the crane beam shakes, it moves the lower beam, which in turn moves the support plate. The damper then supports the support plate, providing better support and buffering the impact force on the support plate.

[0010] In a preferred embodiment, the vibration isolation mechanism includes a first fixed frame, which is fixedly connected to a second mounting plate. A vibration isolator is fixedly connected to the bottom of the first fixed frame, and a second fixed frame is fixedly connected to the bottom of the vibration isolator. Four second springs are fixedly connected to the top of the second fixed frame, and the four second springs are symmetrically distributed on the top of the second fixed frame.

[0011] By adopting the above technical solution, the vibration isolator and spring 2 are installed through fixing frame 1 and fixing frame 2. The vibration isolator isolates the vibration to prevent the crane beam from swaying, and spring 2 resets the vibration isolator, which can better prevent the crane beam from swaying.

[0012] In a preferred embodiment, a plurality of support rods are provided, and the plurality of support rods are distributed intersectingly between the two steel pipe columns.

[0013] By adopting the above technical solution, and by having several support rods arranged in a crisscross pattern between the two steel pipe columns, the steel pipe columns can be better supported.

[0014] In a preferred embodiment, a wear-resistant layer is fixedly connected to the surface of the steel pipe column, and the wear-resistant layer is a ceramic component.

[0015] By adopting the above technical solution, a wear-resistant layer is fixedly connected to the surface of the steel pipe column, and the wear-resistant layer further enhances the wear resistance of the steel pipe column, thus improving its wear resistance.

[0016] In a preferred embodiment, the surface of the positioning block is provided with a sliding groove, which is adapted to the lower beam.

[0017] By adopting the above technical solution, a groove is opened on the surface of the positioning block, and the lower beam is limited by the groove, which can better limit the lower beam.

[0018] In a preferred embodiment, the lower beam is threaded with a fixing bolt on the side near the positioning block.

[0019] By adopting the above technical solution, a fixing bolt is threadedly connected to the side of the lower beam near the positioning block, and the lower beam and the positioning block are connected by rotating the fixing bolt, which can better connect the lower beam and the positioning block.

[0020] The beneficial effects of this application are: 1. This multi-column support structure for heavy-duty steel crane beams, by setting up an installation plate, steel pipe columns, and support rods, connects the installation plate to the lower beam through positioning blocks, then fixes the steel pipe columns with an installation plate and a pair of installation plates, and then supports the installation plate. Finally, the support rods are arranged crosswise to support adjacent steel pipe columns. This avoids the problem of traditional steel crane beam support structures being unable to reinforce the support columns, which leads to fatigue deformation of the support columns, thus improving practicality.

[0021] 2. This multi-column support structure for heavy-duty steel crane beams, by setting up a fixed frame one, a vibration isolator, a spring two, and a fixed frame two, the vibration isolator and spring two are installed through the fixed frame one and fixed frame two, the vibration isolator isolates vibration to prevent the crane beam from swaying, and the spring two resets the vibration isolator, thus avoiding the problem of traditional steel crane beam support structures that cannot isolate vibration and are prone to swaying, and improving practicality.
