Technical Field

[0001] This application relates to auxiliary devices for steel structure installation, specifically to an auxiliary device for steel structure installation. Background Technology

[0002] Steel structure construction boasts numerous advantages, including short construction cycles, excellent seismic performance, good environmental performance, high space utilization, and aesthetically pleasing designs, leading to its rapid development. Besides the materials used, the construction process is paramount in determining the quality of a steel structure. Currently, when connecting multiple steel structures, especially horizontal beams to vertical steel columns, bolts or welding torches are commonly used. Regardless of the method, the beams must be hoisted and aligned with pre-defined points on the steel columns. In existing technology, this alignment involves lifting the beams to the columns using a crane, followed by manual alignment by workers or with appropriate tools. This process is difficult, time-consuming, and prone to rotation and instability while the beams are suspended, posing a safety hazard. Utility Model Content

[0003] In view of the above problems, this application provides an auxiliary device for steel structure installation, which can facilitate the alignment of steel structure beams and steel structure columns, reduce construction time, and avoid safety hazards.

[0004] According to one aspect of the embodiments of this application, an auxiliary device for steel structure installation is provided. The auxiliary device for steel structure installation includes a movable support platform. Rollers are provided at the bottom of the movable support platform, and a working platform is supported at the top of the movable support platform by a support frame. A locking and lifting component is provided at the top of the working platform. The locking and lifting component includes a fixed lifting mechanism and a flipping locking mechanism. The fixed lifting mechanism is detachably fixed to the top of the working platform. The flipping locking mechanism is rotatably connected to one side of the fixed lifting mechanism via a hinge. A locking component for restricting the rotation of the flipping locking mechanism is provided at the flipping locking mechanism. Opposite L-shaped reinforcing plates are respectively provided on the common side of the flipping locking mechanism and the fixed lifting mechanism. One end of the locking and lifting component is integrally clamp-shaped. Multiple jacks are provided on the top of the side of the fixed lifting mechanism opposite to the reinforcing plate, and the tops of the multiple jacks are connected to a common pressure plate.

[0005] In some embodiments, the locking component includes a through hole extending through the work platform, and a collar matching the through hole is fixedly connected to one side of the flip locking mechanism, with an L-shaped limiting rod inserted inside the collar.

[0006] In some embodiments, a vertical ladder for operators to climb is provided on one side of the support frame.

[0007] In some embodiments, the top of the vertical ladder is provided with a circular support beam, the bottom of the circular support beam is connected to the support frame by a plurality of auxiliary support rods, and the top of the circular support beam is provided with a plurality of guardrails, the top of the guardrails being provided with guardrails.

[0008] In some embodiments, the jacks are grouped in pairs, and the multiple groups of jacks are arranged in a linear array. The tops of the two jacks in each group are hinged to the pressure plate, and the top ends of the pressure plate are bent upwards so that the cross-section of the pressure plate is U-shaped.

[0009] In some embodiments, a receiving groove is provided on one side of the fixed lifting mechanism, a pry bar is provided in the receiving groove, and a fulcrum assembly for supporting the bottom end of the pry bar is provided on the top of the fixed lifting mechanism on one side of the jack.

[0010] The beneficial effects of this application are as follows: By setting a fixed lifting mechanism and a flipping locking mechanism, the device can be stably connected to the steel structure column, thereby giving the device high overall stability and preventing it from overturning and avoiding safety hazards.

[0020] For details, please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the overall installation structure of the device provided in an embodiment of this application. Figure 2 This is a schematic diagram of the overall structure of the device provided in an embodiment of this application. Figure 3 This is a partial structural diagram of the card-positioning lifting component provided in an embodiment of this application. Figure 4This is a schematic diagram of the installation structure of the lifting component provided in this application embodiment. The auxiliary device 100 for steel structure installation includes a movable support platform 110. The bottom of the movable support platform 110 is provided with rollers 111. The movable support platform 110 can be welded from steel. The rollers 111 at its bottom can be used to easily move the entire device to a suitable position for use. It should be noted that during the movement, the top of the device does not bear the load of the steel structure beam 300. After the device is moved to a suitable position and the flipping locking mechanism 142 is connected to the steel structure column 200, the steel structure beam 300 can be transferred to the top of the pressure plate 160 by a crane. The top of the mobile support platform 110 is supported by a support frame 120, which supports a working platform 130. The working platform 130 is opposite to the mobile support platform 110. The support frame 120 connects the working platform 130 and the mobile support platform 110 into one unit. It can be understood that the connection between the mobile support platform 110, the support frame 120, and the working platform 130 can be detachable or integrated. It should be noted that the support frame 120 of different heights can be selected according to different construction sites. Since steel structures are mainly used for factory construction, and factories are usually single-story, the installation height of the steel structure beams 300 is basically the same on the same construction site. Therefore, a suitable support frame 120 height can be selected for welding before construction begins to complete the fabrication of this equipment. Of course, to ensure that this equipment can meet the needs of various construction sites, the support frame 120 can also be set to a height-adjustable form. A locking and lifting component 140 is provided on the top of the work platform 130. The locking and lifting component 140 is used to clamp the steel structure support column and finely adjust the height of the top steel structure crossbeam 300. The locking and lifting component 140 includes a fixed lifting mechanism 141 and a flipping locking mechanism 142. The fixed lifting mechanism 141 is detachably fixed to the top of the work platform 130. The flipping locking mechanism 142 is rotatably connected to one side of the fixed lifting mechanism 141 via a hinge shaft 143. The position of the fixed lifting mechanism 141 is fixed relative to the work platform 130, while the flipping locking mechanism 142 can be flipped along its hinge. A locking component 144 is provided at the flipping locking mechanism 142 to restrict the rotation of the flipping locking mechanism 142. When the flipping locking mechanism 142 moves to a suitable position, the locking component 144 can restrict its flipping, thereby allowing the entire device to be stably connected to the steel structure column 200. The flip-locking mechanism 142 and the fixed lifting mechanism 141 are respectively provided with opposing L-shaped reinforcing plates 145 on the same side. One end of the locking lifting component 140 is generally clamp-shaped. The steel structure column is usually I-beam or T-beam, which both have wing plates. When the flip-locking mechanism 142 is rotated into place, the two L-shaped reinforcing plates 145 will respectively clamp around the wing plate from both sides.The top of the fixed lifting mechanism 141, on the side opposite to the reinforcing plate 145, is equipped with multiple jacks 150, and the tops of the multiple jacks 150 are connected to a pressure plate 160. By adjusting the height of the jacks 150, the pressure plate 160 can be slowly raised or lowered, thereby causing the steel structure beam 300 loaded on the top of the pressure plate 160 to slowly rise or fall.

[0021] In this embodiment, the specific working process is as follows: the device is moved to the side of the steel structure column 200 to be operated by the roller 111, and the L-shaped reinforcing plate 145 at the fixed lifting mechanism 141 is inserted into one side of the wing plate of the steel structure column 200. Then, the overall position of the device is adjusted to align with the central axis of the steel structure column 200. Then, the flipping locking mechanism 142 is pushed to flip around the pivot 143 between it and the fixed lifting mechanism 141. At this time, the L-shaped reinforcing plate 145 on the flipping locking mechanism 142 will surround the other wing plate of the steel structure column 200, and the locking component 144 is opened. At this time, one wing plate of the steel structure support column will be clamped by the two L-shaped reinforcing plates 145, thereby fixing the entire device to one side of the steel structure column 200, thus ensuring the safety and stability of the subsequent construction process. Subsequently, the steel structure cross column is hoisted above the pressure plate 160. After the crane is hoisted into place, the hinge rope is loosened by 10cm to 20cm to ensure that the steel structure beam 300 has a certain amount of free adjustment space. At this time, the operator slowly raises or lowers the steel structure beam 300 by adjusting the height of each jack 150 until the steel structure beam 300 is aligned with the preset point.

[0022] As can be seen from the above, in this embodiment, by setting the fixed lifting mechanism 141 and the flipping locking mechanism 142, the device can be stably connected to the steel structure column 200, thereby giving the device high overall stability and preventing it from overturning and avoiding safety hazards. In this embodiment, by setting the jack 150 and the pressure plate 160 and other components to work together, one end of the steel structure beam 300 can be finely adjusted, so that the steel structure beam 300 can be easily and quickly aligned to the preset point, thereby saving the construction period. In the process of fine-tuning the steel structure beam 300, the end of the beam is pressed against the pressure plate 160. The end of the beam is no longer in a free state but is restricted in displacement by the friction between the pressure plate 160 and the beam, thereby avoiding safety hazards such as pinching hands when the steel structure beam 300 is disturbed by wind.

[0023] In some embodiments, the locking component 144 includes a through hole 144a penetrating the working platform 130. A collar 144b matching the through hole 144a is fixedly connected to one side of the flip-locking mechanism 142, and an L-shaped limiting rod 144c is inserted into the collar 144b. In this embodiment, when the locking mechanism moves into position, the through hole 144a at the working platform 130 will be exposed. At this time, the L-shaped limiting rod 144c can be inserted through the collar 144b and the through hole 144a in sequence. The locking mechanism will then be unable to flip back to its original position. At this time, the entire device can be conveniently and stably connected to the steel structure column 200 by one of the wing plates of the steel structure column 200. The advantage of this embodiment is that the locking component 144 has a simple structure, is easy to manufacture, and is easy to operate.

[0024] In some embodiments, a vertical ladder 170 is provided on one side of the support frame 120 for operators to climb. In this embodiment, by providing the vertical ladder 170, operators can climb to the work platform 130 to perform corresponding operations.

[0025] In some embodiments, a circular support beam 171 is provided at the top of the vertical ladder 170. The bottom of the circular support beam 171 is connected to the support frame 120 via multiple auxiliary support rods 172. Multiple guardrails 173 are vertically provided at the top of the circular support beam 171, and a guardrail 174 is provided at the top of the guardrails 173. In this embodiment, when workers climb the vertical ladder 170, they can pass through the circular support beam 171, and then step onto the support frame 120 to work while relying on the guardrail 174, further enhancing the safety protection of the workers.

[0026] In some embodiments, multiple jacks 150 are grouped in pairs, and the multiple groups of jacks 150 are arranged linearly. The tops of the two jacks 150 in each group are hinged to a pressure plate 160. The top ends of the pressure plate 160 are bent upwards so that the cross section of the pressure plate 160 is U-shaped. In this embodiment, through the above arrangement, the U-shaped pressure plate 160 can effectively prevent the steel structure beam 300 from slipping along its sides. Moreover, since the jacks 150 are grouped in pairs, by adjusting the height of one of the jacks 150 in the same group, the steel structure beam 300 can be tilted in the first axis. By adjusting the height of two adjacent groups of jacks 150, the steel structure beam 300 can be tilted in the second axis. The first axis and the second axis are perpendicular, thereby realizing the adjustment of the steel structure beam 300 in multiple directions.

[0027] In some embodiments, a receiving groove is provided on one side of the fixed lifting mechanism 141, and a pry bar 180 is provided in the receiving groove. The top of the fixed lifting mechanism 141, located on the side of the jack 150, is provided with a fulcrum assembly 181 for supporting the bottom end of the pry bar. In this embodiment, with the above-mentioned arrangement, the operator can remove the pry bar and insert it into the fulcrum assembly 181 to pry the position of the steel structure beam 300 on the pressure plate 160 in sequence, so that it can be aligned with the preset point on the steel structure column 200. It should be noted that the fulcrum assembly 181 here can take various forms, such as grooves or protrusions, as long as it meets the usage requirements.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them.
