Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, specifically a steel structure column hoisting device for building construction. Background Technology

[0002] During construction, steel structure columns, as crucial load-bearing components, directly impact the construction quality and progress of the entire project through the safety, stability, and efficiency of their hoisting operations. Currently, most existing steel structure column hoisting devices employ traditional methods of directly binding the columns with lifting tools. This method has numerous drawbacks and fails to meet the high standards required for modern construction.

[0003] First, the lifting ropes of traditional hoisting devices are mostly set vertically or at random angles. During the hoisting process, the ropes are prone to violent shaking due to factors such as the weight of the hoisting column, wind force, and the swaying of the hoisting equipment. This causes the steel structure hoisting column to deviate from the preset hoisting trajectory, which not only increases the difficulty of hoisting operations but also easily leads to safety accidents such as collisions and falls of the hoisting column, seriously threatening the personal safety of construction personnel and the integrity of construction equipment.

[0004] Secondly, the existing hoisting equipment has an unreasonable support and positioning structure design. Most devices cannot flexibly adapt to steel structure columns of different sizes. When hoisting columns of different specifications, it is necessary to change the corresponding lifting tools or adjust the support structure, which is cumbersome and significantly reduces the efficiency of hoisting operations. At the same time, some support structures have a small contact area with the column and are not firmly positioned. During the hoisting process, the column is prone to displacement and rotation, which leads to friction between the hoisting rope and the surface of the column, causing damage to the surface coating or structural wear, affecting the service life of the column and the subsequent installation accuracy.

[0005] Furthermore, the existing hoisting equipment's rope storage mechanism is flawed. During the preparation and completion phases of hoisting operations, the storage and deployment of the ropes are cumbersome and require manual handling. This not only increases the workload of construction workers but can also disrupt the hoisting operation due to rope tangling and knots. In summary, existing steel structure column hoisting equipment suffers from poor stability, low adaptability, inconvenient loading and unloading, insufficient safety, and low operational efficiency, making it difficult to meet the actual needs of steel structure column hoisting in building construction. Therefore, developing a steel structure column hoisting device for building construction that can solve the above-mentioned technical problems is of significant practical importance. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes a steel structure column hoisting device for building construction.

[0007] The technical solution to achieve the purpose of this invention is as follows: a steel structure column hoisting device for building construction, including a support, a sliding seat at the bottom of the support, a hoisting rope inside the sliding seat, and a support assembly connected to the bottom end of the hoisting rope. The support assembly includes a support base, a connecting pipe, a power supply, a wire, a coil, and a ring magnet. The sliding seat and hoisting rope are arranged in four sets. Four support bases are respectively fixedly connected to the bottom ends of four hoisting ropes. Four connecting pipes are slidably connected between the four support bases. The power supply is installed inside one of the connecting pipes. The wire is electrically connected to the power supply. Eight coils are electrically connected to the wire. Four ring magnets are respectively fixedly connected to the inside of the four support bases. An auxiliary assembly is installed inside the support and the sliding seat.

[0008] Furthermore, the support assembly also includes limiting rods, and the four limiting rods are respectively fixedly connected to the four support bases.

[0009] Furthermore, the auxiliary components include connecting blocks, screw holes, and bolts. Two brackets are provided, and connecting blocks are fixedly connected to both ends of the two brackets. Screw holes are opened on the four connecting blocks. The four connecting blocks are divided into two groups, and the two groups of connecting blocks are fixedly connected by two bolts and two screw holes.

[0010] Furthermore, the two supports are arc-shaped rods with identical shapes, and the two supports can be spliced ​​together. When the two supports are fixed together by connecting blocks and bolts, they will form a closed loop.

[0011] Furthermore, the auxiliary component also includes rotating tubes, four of which are rotatably connected to the interior of four sliding seats, and four suspension ropes are wound around the four rotating tubes.

[0012] Furthermore, the auxiliary assembly also includes fixed rods and springs. The four fixed rods are respectively fixedly connected to the inside of the four sliding seats and located inside the four rotating tubes. The four springs are respectively fixedly connected between the four fixed rods and the inner walls of the four rotating tubes.

[0013] Furthermore, the cross-sections of the four support seats are right-angled trapezoids, and the connecting pipes are "L"-shaped, with each end of the connecting pipe slidably connected to two support seats respectively.

[0014] Firstly, by setting up four sets of sliding seats and lifting ropes, and with the lifting ropes tilted inwards from top to bottom during hoisting, the present invention can effectively limit the swaying amplitude of the lifting ropes, preventing the steel structure column from shifting or swinging during hoisting, and greatly improving the stability of the hoisting operation. At the same time, the limiting rod in the support assembly can abut against the edge of the steel structure column, preventing the lifting rope from directly contacting the surface of the column and causing friction, thus preventing damage to the surface of the column. It also further improves the positioning stability of the column during hoisting and reduces the occurrence of safety accidents.

[0015] Secondly, the support assembly of this invention, through the cooperation of a power supply, wires, coils, and a ring magnet, can change the direction of the current in the coil by controlling the power supply, thereby changing the direction of the magnetic field at the end of the coil. This causes the coil to attract or repel the ring magnet, thereby controlling the connecting pipe to drive the support seat to contract inward or expand outward. This enables flexible clamping and release of steel structure columns of different sizes without the need to change the lifting tools or adjust the structure, greatly improving the adaptability and ease of operation of the device. Furthermore, the support seat is designed with a right-angled trapezoidal cross section. When the support seat expands outward to unload the column, the column can slide smoothly down the inclined surface of the support seat, avoiding collisions and protecting the integrity of the column structure.

[0016] Thirdly, when loading the lifting column, the hoisting device of the present invention only needs to place the column on the support base, and the support base can be closed inward to complete the fixation; during unloading, the support base is expanded outward by starting the power, and the column can automatically slide down the inclined surface of the support base, realizing the rapid separation of the device and the column without manual assistance, which not only improves the efficiency of loading and unloading operations, but also reduces the operational risks of construction personnel; at the same time, the automatic rope storage mechanism, when the bracket is placed on the ground, the spring drives the rotating tube to rotate, which can automatically wind and store the rope into the sliding seat, avoiding rope tangling and knotting, and simplifying the operation preparation and finishing process.

[0017] Fourthly, the bracket of this invention is configured as two arc-shaped rod structures, which can be spliced ​​or disassembled through the cooperation of connecting blocks, screw holes, and bolts. When the weight of the lifting column is small, the two brackets can be spliced ​​to form a closed loop and lifted by a single lifting device; when the weight of the lifting column is large and the requirements for lifting stability are high, the two brackets can be disassembled and lifted by two lifting devices in coordination, which improves the safety and stability of the lifting. At the same time, the disassembled bracket is easier to store and transport, adapting to different construction scenario requirements. Attached Figure Description

[0027] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides an improved steel structure column hoisting device for building construction. The technical solution of this invention is as follows:

[0029] like Figures 1-6As shown, a steel structure column hoisting device for building construction includes a support 1. A sliding seat 2 is provided at the bottom of the support 1, and a hoisting rope 3 is installed inside the sliding seat 2. The specific material of the hoisting rope 3 can be determined according to requirements, such as iron chain or nylon rope. When hoisting the steel structure column, all four hoisting ropes 3 are in an inclined state, tilting inwards from top to bottom. This minimizes the swaying of the hoisting ropes 3 during hoisting. A support assembly 4 is connected to the bottom end of the hoisting rope 3. The support assembly 4 includes a support base 41, a connecting pipe 42, a power supply 43, a wire 44, a coil 45, and a ring magnet 46. Four sets of sliding seats 2 and hoisting ropes 3 are provided. Four support bases 41 are respectively fixedly connected to the bottom ends of four hoisting ropes 3. Four connecting pipes 42 are slidably connected between the four support bases 41. One of the connecting pipes 42 houses the power supply 43 and the wire 44. The system is electrically connected to the power supply 43. Eight coils 45 are electrically connected to the wires 44. The coils 45 are made of metal. When current flows through them, they generate magnetism at the ends due to electromagnetic induction. The direction of the magnetic field is determined by the clockwise or counterclockwise direction of the current in the coils 45. By controlling the direction of the current in the coils 45 through the power supply 43, the direction of the magnetic field at the ends of the coils 45 can be changed, thereby causing the coils 45 and the ring magnets 46 to attract or repel each other. This controls the four connecting tubes 42 to contract inward or expand outward, thereby causing the four support seats 41 to move inward or outward. When the support seats 41 move inward, the steel structure hanging column can be placed. When the support seats 41 move outward, the steel structure hanging column can slide off the support seats 41. The four ring magnets 46 are fixedly connected to the inside of the four support seats 41. The bracket 1 and the sliding seat 2 are equipped with auxiliary components 5.

[0030] In this invention, the support assembly 4 also includes limiting rods 47. The four limiting rods 47 are respectively fixedly connected to the four support seats 41. The limiting rods 47 are used to abut the edge of the steel structure column to prevent the steel structure column and the suspension rope 3 from contacting and causing friction.

[0031] In this invention, the auxiliary component 5 includes a connecting block 51, a screw hole 52, and a bolt 53. There are two brackets 1, and both ends of the two brackets 1 are fixedly connected to the connecting block 51. Each of the four connecting blocks 51 has a screw hole 52. The four connecting blocks 51 are divided into two groups, and the two groups of connecting blocks 51 are fixedly connected by two bolts 53 and two screw holes 52.

[0032] In this invention, the two supports 1 are arc-shaped rods with the same shape. The two supports 1 can be spliced ​​together. When the two supports 1 are fixed together by the connecting block 51 and the bolt 53, they will form a closed loop.

[0033] In this invention, the auxiliary component 5 also includes a rotating tube 55. The four rotating tubes 55 are rotatably connected to the interior of the four sliding seats 2 respectively. The four hanging ropes 3 are respectively wound around the four rotating tubes 55. When the steel structure hanging column is placed on the support seat 41, the bracket 1 needs to be placed on the ground. At this time, the hanging ropes 3 can be stored in the sliding seat 2 and wound around the rotating tubes 55.

[0034] In this invention, the auxiliary component 5 also includes fixed rods 54 and springs 56. The four fixed rods 54 are respectively fixedly connected to the inside of the four sliding seats 2. The four fixed rods 54 are respectively located inside the four rotating tubes 55. The four springs 56 are respectively fixedly connected between the four fixed rods 54 and the inner walls of the four rotating tubes 55. Under the action of the springs 56, when the bracket 1 is placed on the ground, the springs 56 will cause the rotating tubes 55 to rotate, so that the suspension ropes 3 will automatically wind around the rotating tubes 55, so that the suspension ropes 3 will be stored in the sliding seats 2. When the bracket 1 is lifted by a crane or other equipment, the weight of the steel structure column will cause the four support seats 41 to move downward, so that the four suspension ropes 3 will be stretched downward to their longest state.

[0035] In this invention, the cross-sections of the four support seats 41 are right trapezoidal. Therefore, when the four support seats 41 expand outward, the steel structure hanging column located on the support seats 41 will gradually slide off the four support seats 41 without causing collision. The connecting pipe 42 is L-shaped, and both ends of each connecting pipe 42 are slidably connected to two support seats 41 respectively. Therefore, as long as the four connecting pipes 42 expand outward respectively, they can drive the four support seats 41 to expand outward.

[0036] The specific working method is as follows: First, place two brackets 1 and four support seats 41 on the ground. At this time, the four support seats 41 will be inside the brackets 1. The steel structure hanging column can be placed directly on the four support seats 41 from above. The four support seats 41 are brought together towards the middle until the four limit rods 47 abut against the edge of the steel structure hanging column, thus fixing the steel structure hanging column. At this time, simply lift the brackets 1 upwards to connect the brackets 1 with equipment such as cranes, thereby lifting the entire device so that the steel structure hanging column on it can be transported.

[0037] When the device, along with the steel structure column, is moved to the target position, the power supply 43 can be activated. Current is generated in the power supply 43 wires 44 and coils 45. When there is current in the coils 45, their ends will generate magnetism. Therefore, the ends of all eight coils 45 will generate magnetism. The magnetism generated by the coils 45 and the magnetism of the ring magnet 46 repel each other, causing the four connecting pipes 42 to slide and the four support seats 41 to expand outward together. The steel structure column located on the four support seats 41 will lose the support of the support seats 41. The bottom end of the steel structure column will then contact the inclined surface on the support seat 41. As the support seat 41 expands outward, the steel structure column will gradually slide down along the inclined surface on the support seat 41 until it is completely separated from the support seat 41. At this time, the device is completely separated from the steel structure column. Pulling the device upward directly will detach the device from the steel structure column, thus preventing the steel structure column from colliding during the unloading process. The device can also be moved directly upward, thus moving away from the steel structure column.

[0038] Both ends of the two supports 1 are fixed with connecting blocks 51. The four connecting blocks 51 are divided into two groups, and each of them has screw holes 52. Therefore, the two groups of connecting blocks 51 can be fixed together by two bolts 53. Thus, the two supports 1 can be spliced ​​together to form a whole, or they can be separated from each other. That is, the supports 1 can be lifted as a whole by hoisting equipment. When the weight of the steel structure column is large and the stability during the hoisting process is required to be higher, the supports 1 can be divided into two, and the two supports 1 can be connected and lifted by two hoisting equipment working together.

[0039] The technical means disclosed in this invention are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this invention are common knowledge to those skilled in the art.
