Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, specifically to a steel beam lifting device for assembling steel structure workshops. Background Technology

[0002] The main load-bearing components of steel structure factory buildings are made of steel. This type of structure has advantages such as high strength, short construction period, reliable quality, and recyclable materials, making it widely used in single-story, large-span buildings such as factories, warehouses, and aircraft hangars. Its general structure includes load-bearing columns, ridge, roof frame, and purlins. The purlins are located on the roof and are generally made of C-shaped steel, Z-shaped steel, or I-beams. Among them, Z-shaped steel or I-beams have better load-bearing capacity as purlins, so most factory buildings use these two types of steel as purlins.

[0003] The accuracy and strength of purlin installation directly affect the overall strength and wind resistance of the roof. Therefore, purlin installation is one of the most important steps in constructing a steel structure factory building. However, due to their structural design, Z-shaped steel and I-beams are difficult to position precisely, and steel purlins are quite heavy. Therefore, the following problems may arise during their installation: 1. The purlins are located on high roofs, and there are many of them. In addition, steel purlins are heavy and long, making manual handling very laborious and time-consuming. While ordinary lifting equipment can lift the purlins onto the roof, workers still need to manually drag them to the installation position. During this dragging process, workers may lose balance. 1. There is a risk of damage to the purlins; and since the purlins need to be installed on the roof frame, the spacing between the roof frames is less than the length of the purlins. During transportation, the already installed roof frames may interfere with and obstruct the transport of the purlins; 2. Before workers can evenly install the purlins on the roof frame, they need to be temporarily fixed to their installation positions on the roof frame. However, the roof frames of steel factory buildings are generally sloping, making it difficult to temporarily fix the purlins on them, which is very inconvenient for installation; 3. Purlins are generally equipped with threaded holes for installing steel tiles. To ensure that the spacing of these threaded holes is equal, the ends of the front and rear purlins need to be connected without gaps to ensure the accuracy of the subsequent installation of steel tiles.

[0031] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0032] See Figure 1 A steel beam lifting device for assembling steel structure workshops includes a main frame 1, which includes several telescopic rods 11. A base plate 12 is connected to the lower side of each telescopic rod 11. Adjustable rail groups 2 are respectively provided on the front and rear sides of the base plate 12. The front and rear sides of the base plate 12 slide on the adjustable rail groups 2. A rail plate 13 is connected to the upper side of each telescopic rod 11. A lifting hydraulic cylinder 14 is provided on the upper side of the base plate 12 and at the center surrounded by multiple telescopic rods 11. The piston rod of the lifting hydraulic cylinder 14 is connected to the lower side of the rail plate 13. Two front-to-back sliding rails 131 are provided on the upper side of the rail plate 13. An adjustment component 3 is slidably connected to the upper side of the sliding rails 131.

[0033] The adjustment component 3 of this invention can effectively fix the steel purlins and support them on the roof. The adjustment component 3 can also adjust the front and rear positions of the steel purlins and rotate them by a certain angle to avoid interference with the roof frame during the lifting process. This invention can achieve the purpose of evenly spaced steel purlins by adjusting the positioning holes 121 and positioning nails 122 on the track assembly 2. Furthermore, this invention is equipped with multiple clamping components 35, which can lift and position multiple steel purlins at once. Workers on the ground only need to cooperate with workers on the roof to adjust the position of the base plate 12 to complete the vertical positioning of the steel purlins, saving time and effort and ensuring safety for workers on the roof.

[0034] The adjustment component 3 can tilt the purlins arranged in a row at a certain angle to adapt to the angle of the roof frame. Workers only need to adjust the purlins to the installation position to begin installation, and multiple purlins can be installed at once, which is convenient and quick. The lead screw 132 and the clamping assembly 35 of this invention cooperate to move the front and rear purlins along their length direction, so that there are no gaps at the ends, thus ensuring installation accuracy. In this process, workers only need to turn the crank handle 133 to adjust the position, ensuring that the spacing of the threaded holes is equal and that the workers above are always in a relatively safe position, saving effort and improving efficiency. The adjustment track group 2 of this invention can use the existing building's support columns as a reference to accurately position the entire system, and can make the entire system slide or be positioned on the main track, so that a row of purlins can be installed in one positioning, which is convenient, quick and efficient.

[0035] See Figures 1-3The adjusting track assembly 2 includes a main guide rail 21 slidably connected to the base plate 12. Branch guide rails 22 are inserted into both ends of the main guide rail 21. The two ends of the main guide rail 21 have complementary mortise and tenon structures. Multiple positioning holes 121 arranged along the length of the main guide rail 21 are provided on the side of the main guide rail 21 away from the base plate 12. Positioning holes 121 are also provided at corresponding positions on the front and rear sides of the base plate 12. Positioning pins 122 are provided in the positioning holes 121. The two sides of one end of the branch guide rail 22 have complementary mortise and tenon structures, and the other end is provided with a movable plate 221. The movable plate 221 is connected to the end face of the branch guide rail 22 by adjusting bolts.

[0036] This invention allows for the equal-spaced placement of steel purlins by adjusting the positioning holes 121 and positioning pins 122 on the track assembly 2. The track assembly 2 can utilize the existing building's support columns as a reference for precise positioning of the entire system, and the entire system can slide or be positioned on the main track, allowing for the installation of a row of purlins in a single positioning operation, which is convenient, fast, and efficient. Furthermore, both the main guide rail 21 and the branch guide rail 22 of this invention are equipped with mortise and tenon structures that cooperate with each other, allowing for flexible disassembly and installation, and making it suitable for support columns with different widths and spacings.

[0037] Specifically, before starting the jacking, the number of main guide rails 21 needs to be determined based on the distance between the two support columns. Then, the branch guide rails 22 on both sides are inserted into the mortise and tenon structures at both ends of the main guide rail 21. At the same time, the adjusting bolts on the movable plate 221 are loosened so that the support column is stuck between the movable plate 221 and the branch guide rail 22. Then, the adjusting bolts are tightened. After the adjustment of the rail group 2 is completed, the positioning pins 122 in the positioning holes 121 are unscrewed. At the same time, the base plate 12 is adjusted to the appropriate position. Then, the positioning pins 122 in the positioning holes 121 are tightened. Then, the next step can be started.

[0038] See Figure 1 , Figure 4 , Figure 6 The adjustment assembly 3 includes a sliding plate 31 slidably connected to the upper side of the slide rail 131. An angle hydraulic cylinder 32 is hinged to the left side of the sliding plate 31. The piston rod of the angle hydraulic cylinder 32 faces upward. A comprehensive mounting block 33 is hinged to the top of the piston rod of the angle hydraulic cylinder 32. The left end of the comprehensive mounting block 33 is hinged to the top of the piston rod of the angle hydraulic cylinder 32, and the right end is hinged to the sliding plate 31. A power hydraulic cylinder 34 is provided on the lower side of the comprehensive mounting block 33. A lead screw 132 in the front-back direction is provided on the upper side of the track plate 13. The lead screw 132 passes through the sliding plate 31, and a crank handle 133 is provided at the front end of the lead screw 132.

[0039] See Figures 5-6The integrated mounting block 33 has a hollow internal structure. A left-right oriented sliding groove 331 is provided at the bottom of the integrated mounting block 33 and in front of the piston rod of the power hydraulic cylinder 34. Multiple gears 332 are provided inside the integrated mounting block 33. A rack 333 meshes with one side of the gear 332. The rack 333 passes through the sliding groove 331 and connects to the power hydraulic cylinder 34. An opening is provided at the corresponding position of the rack 333 on the left side of the integrated mounting block 33 to facilitate the free movement of the rack 333. Multiple clamping components 35 are arranged side by side in the left-right direction on the upper side of the integrated mounting block 33. The number of clamping components 35 is the same as that of the gears 332. The upper end of the gear 332 passes through the upper side of the integrated mounting block 33 and connects to its corresponding clamping component 35 one by one.

[0040] See Figure 4 ,、 Figure 9 The front side of the integrated mounting block 33 is provided with multiple L-shaped storage slots 334. An L-shaped stop bar 335 is hinged in the storage slot 334. The right side of the L-shaped stop bar 335 is hinged in the storage slot 334. The end of the L-shaped stop bar 335 perpendicular to the upper side of the integrated mounting block 33 is a hollow structure, and a movable stop block 336 is provided inside. The movable stop block 336 and the L-shaped stop bar 335 are connected by a spring.

[0041] The adjustment component 3 of this invention can adjust the front and rear positions of the steel purlins, and can also rotate the steel purlins at a certain angle to avoid interference with the roof frame during the jacking process. It can also tilt the purlins arranged in a row at a certain angle to adapt to the angle of the roof frame. Workers only need to adjust the purlins to the installation position to start the installation, and multiple purlins can be installed at one time, which is convenient and quick. Specifically, after the base plate 12 is in the appropriate position, the purlins can be loaded. It should be noted that the end of this invention with the handle should be aligned with the direction of movement for laying the purlins.

[0042] Specifically, firstly, the purlin is mounted on the clamping assembly 35, which secures the purlin. Simultaneously, the lifting hydraulic cylinder 14 extends, lifting the purlin upwards. When it reaches the gap between the two roof trusses, the power hydraulic cylinder 34 extends a certain length, driving the rack 333 to move parallel to the slide groove 331. The rack 333 drives multiple gears 332 meshing with it to rotate. The gears 332 drive the clamping assembly 35 to rotate synchronously at a certain angle, causing the purlin to tilt at a certain angle to smoothly pass through the gap between the two roof trusses. After passing through the gap, the power hydraulic cylinder 34 retracts, driving the clamping assembly 35 back to its original angle. Hydraulic cylinder 32 begins to lift, tilting the entire integrated mounting block 33 at a certain angle so that its tilt angle matches the roof tilt angle. Then, the worker on the roof needs to unscrew the L-shaped stop bar 335 from the storage slot 334. As it is unscrewed, the movable stop block 336 pops out. The movable stop block 336 is placed against one end of the purlin. The crank handle 133 is rotated, and the purlin is finely adjusted along its length by moving the sliding plate 31 until it is close to the end of other purlins or has reached the installation position. At the same time, the clamping assembly 35 also provides an auxiliary force along its length to the purlin, making it firmly attached to other purlins, so that the worker can fix it.

[0043] See Figure 4 , Figures 7-8 The clamping assembly 35 includes a limiting block 351 with a U-shaped cross-section. A clamping hydraulic cylinder 352 is mirror-arranged on both the left and right outer sides of the limiting block 351. A through-flow groove 353 is provided on the left and right outer sides of the limiting block 351, located in front of the piston rod of the clamping hydraulic cylinder 352. A guide groove 356 is provided on the upper sides of both ends of the limiting block 351, corresponding to the positions of the stroke grooves 353. The guide groove 356 has the same length as the stroke groove 353, and the two guide grooves 356 combine to form a figure-eight shape with the flared opening facing forward. The piston rod of the clamping hydraulic cylinder 352 extends outward, and a 7-shaped sliding sleeve 354 is provided at the top of the piston rod.

[0044] See Figure 4 , Figures 7-8 A section of the vertical sliding sleeve 354 on the upper side of the integrated mounting block 33 is connected to the top of the piston rod. A section of the sliding sleeve 354 parallel to the upper side of the integrated mounting block 33 is a hollow structure. A top extension block 355 is slidably connected inside the hollow structure. The top extension block 355 passes through the stroke groove 353 and is connected to a pressure plate 357. An elastic rubber column 358 is provided on the side of the pressure plate 357 away from the top extension block 355. A guide column 359 is provided on the upper side of the part of the top extension block 355 that passes through the stroke groove 353. The guide column 359 is located in the guide groove 356. The guide column 359 and the guide groove 356 cooperate to achieve the purpose of clamping the hydraulic cylinder 352 while it extends, and clamping the pressure plates 357 on both sides inward.

[0045] The multiple clamping components 35 provided in this invention can lift and position multiple steel purlins at once. Workers on the ground only need to cooperate with workers on the roof to adjust the position of the base plate 12 to complete the vertical positioning of the steel purlins, which saves time and effort and is very safe for workers on the roof. In addition, the clamping components 35 provided in this invention can clamp the purlins and then push them out a distance along the length direction, so as to firmly attach the purlins to be installed to other purlins, making it easier to install them.

[0046] Specifically, when the worker places the purlin on the upper limit block 351, the left and right outer sides of the upper limit block 351, located in the clamping hydraulic cylinder 352, begin to push out, causing the extension blocks 355 in the sliding sleeve 354 to move backward along the stroke groove 353. Due to the action of the guide post 359 and the guide groove 356, the extension blocks 355 on the left and right sides of the upper limit block 351 move backward along the stroke groove 353 and begin to move closer to each other until the pressure plate 357 clamps the purlin in the middle and the clamping hydraulic cylinder 352 stops extending. When the worker rotates the crank handle 133, the clamping hydraulic cylinder 352 continues to push forward again, extending the clamped purlin along its length.

[0047] Since the pressure plate 357 will be squeezed inward during the ejection process, the present invention provides an elastic rubber column 358 on the side of the pressure plate 357 away from the ejector block 355. On the one hand, it can increase the friction force on the purlin. On the other hand, because the elastic rubber column 358 can deform when the pressure plate 357 is squeezed inward during the ejection process, it buffers the squeezing force, protects the purlin from being crushed, and also ensures the safety of the present invention.

[0048] After adjusting the position of the purlins, the workers can fix and install them. After installation, the clamping hydraulic cylinder 352 is released, and then the workers rotate the L-shaped stop bar 335 back into the storage groove 334. Then the lifting hydraulic cylinder 14 retracts, driving the entire system to descend. Then the workers readjust the position of the base plate 12 along the main guide rail 21 and proceed with the installation of the next set of purlins. After one row of purlins is installed, the workers need to remove the adjusting rail group 2 and reposition and construct the next row in the same way.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
