[0007] Beneficial effects:

[0008] This steel structure assembly device achieves efficient and precise assembly of steel structures through the coordinated use of a working platform on the main body and multiple horizontal drive components. The protruding holes on the working platform allow pulleys in the horizontal drive components to easily extend into and contact the steel structure, thereby driving the steel structure to move horizontally and adjust its position. Furthermore, the retractable design of the pulleys not only facilitates operation but also allows them to quickly retract under the working platform after adjustment, avoiding interference with subsequent assembly work. At the same time, the device has a simple structure and is easy to operate, greatly improving the efficiency and accuracy of steel structure assembly while reducing labor and time costs.

[0009] In one alternative embodiment, the horizontal drive assembly further includes a drive structure connected to the pulley, the drive structure being adapted to drive the pulley to move to switch between a working state and a reset state.

[0010] Beneficial effects:

[0011] The drive structure can drive the pulley to complete the working state or the reset state. The design of the drive structure allows the operator to easily control the movement of the pulley, thereby achieving precise adjustment of the position of the steel structure.

[0012] In one optional embodiment, the drive structure includes a hydraulic cylinder, a hydraulic pipe, and a hydraulic pump. The hydraulic cylinder is disposed below the protruding hole, the pulley is disposed at the output end of the hydraulic cylinder, and the hydraulic cylinder is connected to the hydraulic pump through the hydraulic pipe.

[0013] Beneficial effects:

[0014] The hydraulic pump provides the power source for the entire drive structure, while the hydraulic pipes serve as conduits connecting the pump and cylinders, transmitting hydraulic oil and thus power. This design is simple in structure, easy to operate, and possesses high stability and reliability, meeting the requirements for precise position adjustment during steel structure assembly.

[0015] In one alternative embodiment, the pulley has a pulley base, which is fixedly disposed at the output end of the hydraulic cylinder.

[0016] Beneficial effects:

[0017] The pulley base is fixedly connected to the output end of the hydraulic cylinder, which prevents the pulley from shaking or shifting during movement, thus ensuring the positional accuracy of the steel structure during assembly.

[0018] In one optional embodiment, the pulley is rotatably mounted on the pulley base, and the pulley base is provided with a direction locking member, which is used to limit the rotation direction of the pulley.

[0019] Beneficial effects:

[0030] In one optional embodiment, the working platform is composed of double-I-beams with a cavity inside, and the horizontal drive assembly is disposed within the cavity.

[0031] Beneficial effects:

[0032] The work platform adopts a double-I-beam structure design, which not only has a high load-bearing capacity, but also provides space for the horizontal drive components to be installed within the double-I-beam structure, making the entire device more compact and reducing the footprint. The hydraulic cylinder is housed within the cavity. During operation, the pulley extends from its extension hole and contacts the steel structure, driving its movement. In the non-operating state, the pulley is completely contained within the cavity, preventing interference with the work platform and protecting it from environmental damage, thus extending its service life.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, a steel structure assembly device is provided, comprising: a main body 1 and multiple horizontal drive components 2.

[0047] Specifically, the main body 1 has a working platform 11, and the working platform 11 has multiple protrusion holes 12. Horizontal drive components 2 are arranged below the working platform 11, and each horizontal drive component 2 corresponds to one protrusion hole 12. The horizontal drive component 2 includes a pulley 21, which has a working state of extending into the protrusion hole 12 and abutting against the steel structure, and a reset state of moving away from the steel structure.

[0048] In this embodiment, the work platform 11 is used to support the steel structure to facilitate its assembly. The work platform 11 has multiple protruding holes 12, spaced apart along its guide direction. Each horizontal drive component 2 corresponds to one protruding hole 12. During operation, when the position of the steel structure needs adjustment, pulleys 21 extend into the protruding holes 12 and contact the steel structure on the work platform 11. The steel structure moves horizontally via the pulleys 21 to adjust its position. When adjusting the position of the steel structure, hoisting equipment, such as an electric hoist, is required to reduce friction between the steel structure and the work platform 11. Once the position of the steel structure is adjusted, the pulleys 21 retract below the work platform 11, and the steel structure is then placed on the work platform 11.

[0049] This steel structure assembly device achieves efficient and precise assembly of steel structures through the coordinated use of a working platform 11 on the main body 1 and multiple horizontal drive components 2. The protruding holes 12 on the working platform 11 allow the pulleys 21 in the horizontal drive components 2 to easily extend into and contact the steel structure, thereby driving the steel structure to move horizontally and adjust its position. Furthermore, the retractable design of the pulleys 21 not only facilitates operation but also allows them to quickly retract under the working platform 11 after adjustment, avoiding interference with subsequent assembly work. Simultaneously, the device has a simple structure and is easy to operate, greatly improving the efficiency and accuracy of steel structure assembly while reducing labor and time costs.

[0050] In one embodiment, the horizontal drive assembly 2 further includes a drive structure connected to the pulley 21, the drive structure being adapted to drive the pulley 21 to move to switch between a working state and a reset state.

[0051] Specifically, such as Figure 3As shown, the drive structure can drive pulley 21 to either the working state or the reset state. The design of the drive structure allows the operator to easily control the movement of pulley 21, thereby achieving precise adjustment of the steel structure's position. When the steel structure's position needs to be adjusted, the drive structure is activated, driving pulley 21 to extend into the protrusion hole 12 and contact the steel structure. The pulley 21 then drives the steel structure to move horizontally until it reaches the predetermined position. After adjustment, the drive structure is activated again, driving pulley 21 to retract below the work platform 11 for subsequent assembly work.

[0052] In one embodiment, the drive structure includes a hydraulic cylinder 22, a hydraulic pipe 23, and a hydraulic pump 24. The hydraulic cylinder 22 is located below the extension hole 12, and the pulley 21 is located at the output end of the hydraulic cylinder 22. The hydraulic cylinder 22 is connected to the hydraulic pump 24 through the hydraulic pipe 23.

[0053] Specifically, such as Figure 3 As shown, the hydraulic pump 24 supplies oil to drive the piston rod of the hydraulic cylinder 22 to extend or retract, thereby driving the pulley 21 to complete the working state or reset state. The hydraulic pump 24 provides the power source for the entire drive structure, and the hydraulic pipe 23 serves as the pipeline connecting the hydraulic pump 24 and the hydraulic cylinder 22, transmitting hydraulic oil and realizing the transmission of power. This design is simple in structure, easy to operate, and has high stability and reliability, which can meet the requirements for precise position adjustment during the assembly of steel structures.

[0054] In one embodiment, pulley 21 has pulley base 25, which is fixedly disposed at the output end of hydraulic cylinder 22.

[0055] Specifically, such as Figure 4 As shown, the design of the pulley base 25 allows the pulley 21 to be stably mounted on the output end of the hydraulic cylinder 22, ensuring the stability and reliability of the pulley 21 during operation. The pulley base 25 is fixedly connected to the output end of the hydraulic cylinder 22, preventing the pulley 21 from shaking or shifting during movement, thereby ensuring the positional accuracy of the steel structure during assembly.

[0056] In one embodiment, the pulley 21 is rotatably mounted on the pulley base 25, and the pulley base 25 is provided with a direction locking member, which is used to limit the rotation direction of the pulley 21.

[0057] Specifically, such as Figure 4As shown, pulley 21 is a universal wheel, allowing the steel structure to move in multiple directions. A directional locking element (not shown) is installed on the pulley base 25. This locking element can be adjusted to lock the pulley 21 in the desired direction, preventing it from rotating and allowing the steel structure to move only in one horizontal direction. By installing the directional locking element, it is ensured that when precise positioning of the steel structure is required, pulley 21 can move stably in a specific direction, avoiding unnecessary offset or swaying, thereby further improving the positional accuracy and stability of the steel structure assembly. The directional locking element is a known and publicly available technical means, and therefore will not be described in detail.

[0058] In one embodiment, the main body 1 further includes a limiting member 13, which is disposed on the extension side of the working platform 11.

[0059] Specifically, such as Figure 2 As shown, the left and right sides of the work platform 11 are the extension sides of the work platform 11. The limiting parts 13 are set on both sides of the work platform 11 to limit the steel structure on the work platform 11 and prevent the steel structure from slipping off the work platform 11 during the assembly process, thereby further ensuring the safety and stability of the steel structure assembly.

[0060] Preferably, the limiting member 13 is a channel steel, and the channel steel is perpendicular to the working platform 11.

[0061] In one embodiment, the main body 1 further includes an auxiliary support frame 14, which is disposed on one side of the working platform 11, and the top of the auxiliary support frame 14 has an inclined support portion 15.

[0062] Specifically, such as Figure 1 and Figure 5 As shown, the inclined support 15 abuts against the inclined surface of the steel structure. The auxiliary support frame 14 and the inclined support 15 cooperate with each other to support the inclined surface of the steel structure, further improving the stability and reliability of the steel structure during assembly. By setting the auxiliary support frame 14, not only is the load-bearing capacity of the entire device enhanced, but the steel structure is also easier to position and fix during assembly, thereby further improving assembly efficiency and accuracy.

[0063] In one embodiment, the auxiliary support frame 14 is interconnected with the work platform 11 via a connector 16.

[0064] Specifically, such as Figure 1 and Figure 2As shown, the connector 16 serves to connect the auxiliary support frame 14 and the working platform 11. The two ends of the connector 16 can be welded and fixed to the auxiliary support frame 14 and the working platform 11 respectively, or fixed with fasteners such as bolts. The connector 16 makes the auxiliary support frame 14 and the working platform 11 a whole structure, which effectively improves the stability of the main body 1.

[0065] In one embodiment, the working platform 11 is composed of double-I-beams with a cavity inside, and the horizontal drive assembly 2 is disposed inside the cavity.

[0066] Specifically, such as Figure 1 and Figure 2 As shown, the work platform 11 adopts a double-I-beam structure design, which not only has a high load-bearing capacity, but also provides space for the horizontal drive component 2 to be installed within the double-I-beam structure, making the entire device more compact and reducing the floor space occupied. The hydraulic cylinder 22 is located within the cavity. During operation, the pulley 21 extends from the extension hole 12 and abuts against the steel structure, driving the steel structure to move. In the non-operating state, the pulley 21 is completely contained within the cavity, preventing interference with the work platform 11 and protecting it from external environmental damage, thus extending its service life. The hydraulic pump 24 is located outside the cavity. One end of the hydraulic pipe 23 extends into the cavity and connects to the hydraulic cylinder 22, while the other end connects to the hydraulic pump 24 outside the cavity.

[0067] In one embodiment, the auxiliary support frame 14 has an inclined support rod 3 on the side away from the working platform 11. One end of the inclined support rod 3 is fixedly connected to the auxiliary support frame 14, and the other end of the inclined support rod 3 abuts against the ground.

[0068] Specifically, such as Figure 1 As shown, the design of the inclined support rod 3 further enhances the stability of the auxiliary support frame 14, preventing it from tipping over or swaying under load. One end of the inclined support rod 3 is fixedly connected to the auxiliary support frame 14, while the other end rests against the ground, forming a stable triangular support structure that makes the auxiliary support frame 14 more stable and reliable when bearing the weight of the steel structure.

[0069] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
