Technical Field

[0001] The present invention relates to the technical field of lifting equipment, and particularly relates to a lifting equipment for long-span steel structures. Background Technique

[0002] Steel structures are widely used in fields such as construction. They can enhance the stability of buildings. When handling steel structures, especially long-span steel structures such as flat steel plates, U-shaped steel plates, and I-shaped steel plates, lifting equipment is needed to move them.

[0003] Chinese Patent with the publication number of "CN118108100A" discloses "a lifting auxiliary device for a steel structure reticulated shell, including a lifting plate and a lifting ring. A lifting member is fixedly arranged below the lifting ring, and a rotating member is rotatably arranged in the lifting member. It also includes: a moving limiting mechanism, which is used to connect the lifting plate and the rotating member". Although it can achieve the effect of "quickly adjusting the balanced position point of the reticulated shell after being lifted through the moving limiting mechanism according to actual lifting requirements, and the use is more flexible", it is only suitable for lifting steel structure reticulated shells, and its use has limitations and cannot lift other steel structures such as U-shaped steel plates. In addition, other lifting equipment needs to avoid shaking during the lifting process. The auxiliary lifting equipment will throw out the lifted materials in the case of shaking, and the lifting safety is not high. Therefore, the present invention proposes a lifting equipment for long-span steel structures. Summary of the Invention

One end of the guide rod is fixedly connected to a baffle. An anti-slip pad is fixedly arranged on one side of the baffle. The U-shaped plate is fixedly connected to the sliding plate. A second spring is arranged between the guide rod and the U-shaped plate.

[0010] As a preferred technical solution of the present invention, several placement holes are opened at the top of the support plate, and two fixing rods penetrate and are rotatably connected to the support plate. Three pulleys are fixedly arranged on the outer part of the fixing rod, and the pulleys are adaptively matched with the placement holes.

[0011] As a preferred technical solution of the present invention, the storage rack is adaptively matched with the I-shaped plate. The bolt fastener is composed of a bolt and a nut.

[0012] As a preferred technical solution of the present invention, two groups of anti-shake structures are arranged at the bottom of the mounting plate. The anti-shake structure includes a base, two fixing plates, several movable rods, two second clamping blocks, and two connecting plates. The base is fixedly connected to the mounting plate. The fixing plate is fixedly connected to the base. The movable rod penetrates and is connected to the fixing plate. The second clamping block and the connecting plate are both fixedly connected to the movable rod. Several third springs are arranged between the second clamping block and the fixing plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting the grasping structure, it is beneficial to perform the limiting work according to the size of the U-shaped steel plate or other shaped steel structures. When the equipment shakes during the hoisting process, the first clamping block prevents the sliding plate from retreating, so that the U-shaped steel plate can be clamped more tightly during the hoisting process, greatly improving the safety of the equipment during the hoisting process;

[0019] 2. By setting the control component in cooperation with the grasping structure, it is beneficial to press several first clamping blocks together after the hoisting is completed, which is convenient for the limited sliding plate to return to the initial position, greatly reducing the cumbersome links of pressing one by one and improving the work efficiency;

[0020] 3. By setting the side limiting component in cooperation with the grasping structure, it is beneficial to limit the side of the U-shaped steel plate, so that the side of the U-shaped steel plate is restricted during the hoisting process. At the same time, the setting of the anti-slip pad greatly enhances the friction force, avoiding the situation of shaking caused by the lack of side limit of the U-shaped steel plate;

[0021] 4. By setting the rope, the anti-shaking structure in cooperation with the grasping structure, it is beneficial to limit the position of the I-shaped plate, avoid large-amplitude shaking of the I-shaped plate during the hoisting process, which affects the handling efficiency, and at the same time can further improve the safety of the hoisting;

[0022] 5. By setting the thrust component in cooperation with the anti-shaking structure, it is beneficial to move the second clamping block away when needed, so that the restriction on the I-shaped plate inside the base is released, and the I-shaped plate can move down for work;

[0023] 6. By setting a limit structure in conjunction with an anti-sway structure, it is helpful to guide and limit the I-beam during its upward movement, and can guide the I-beam to gradually fit into the base, preventing the I-beam from deviating and failing to fit into the predetermined position of the base due to shaking when moving upward.

Specific embodiments

[0038] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0039] As Figures 1-13 shown, a lifting device for large-span steel structures includes a mounting plate 1. Three vertical plates 2 are fixedly arranged at the top of the mounting plate 1. A linkage rod 3 is rotatably connected through the three vertical plates 2. One end of the linkage rod 3 penetrates through one of the vertical plates 2 and is fixedly connected to the output shaft of the motor 4. Two winding rollers 5 are fixedly arranged on the outer part of the linkage rod 3. A rope 6 is arranged on the outer part of the winding roller 5. A grasping structure 7 is arranged between one ends of the two ropes 6;

[0040] The grasping structure 7 includes an I-shaped plate 10 and several groups of grasping components. The I-shaped plate 10 is fixedly connected to one end of the rope 6. Several groups of grasping components are arranged on the outer part of the I-shaped plate 10. The grasping components include a storage rack 11 and a horizontal plate 12. The storage rack 11 is connected to the I-shaped plate 10 through a bolt fastener 14. Two sliding plates 13 are slidably arranged on the outer part of the horizontal plate 12. Two connecting arms 15 are rotatably connected to the bottom of the storage rack 11. One end of the connecting arm 15 is rotatably connected to a fixing bracket one 16. The fixing bracket one 16 is fixedly connected to the sliding plate 13. A supporting plate 17 is fixedly connected to the bottom of the sliding plate 13.

[0041] The grasping structure 7 can perform a limiting operation according to the size of the U-shaped steel plate or other shaped steel structures. When the equipment shakes during the hoisting process, the first clamping block 20 prevents the sliding plate 13 from retracting, enabling the U-shaped steel plate to be grasped more tightly during hoisting, thereby greatly improving the safety of the equipment during hoisting.

[0042] In this embodiment, a plurality of slots 18 are formed at the top of the cross plate 12, and the first clamping block 20 is slidably arranged inside the slot 18. Two first springs 21 are arranged between the bottom of the first clamping block 20 and the inner bottom surface of the slot 18. A storage groove 19 is formed inside the cross plate 12. The grasping assembly further includes a control assembly, which includes a second fixing frame 22. The second fixing frame 22 is fixedly connected to the cross plate 12. The second fixing frame 22 is threadedly connected with a threaded rod 23. One end of the threaded rod 23 is rotatably connected to a pressing plate 24. The pressing plate 24 is adaptively matched with the storage groove 19 and the first clamping block 20, and both the storage groove 19 and the pressing plate 24 are in an H shape.

[0043] The control assembly cooperates with the grasping structure 7 to press a plurality of first clamping blocks 20 together after hoisting, facilitating the sliding plate 13 that is limited to return to its initial position, greatly reducing the cumbersome steps of pressing one by one, and improving work efficiency.

[0044] In this embodiment, the grasping assembly further includes two sets of side limiting assemblies. The side limiting assembly includes a guide rod 25 and a U-shaped plate 28. The guide rod 25 is connected through the sliding plate 13. One end of the guide rod 25 is fixedly connected to a baffle 26. An anti-slip pad 27 is fixedly arranged on one side of the baffle 26. The U-shaped plate 28 is fixedly connected to the sliding plate 13. A second spring 29 is arranged between the guide rod 25 and the U-shaped plate 28.

[0045] The side limiting assembly cooperates with the grasping structure 7 to limit the side of the U-shaped steel plate, so that the side of the U-shaped steel plate is restricted during hoisting. At the same time, the setting of the anti-slip pad 27 greatly enhances the friction force, avoiding the situation of shaking caused by the lack of side restriction of the U-shaped steel plate.

[0046] In this embodiment, a plurality of storage holes 30 are formed at the top of the support plate 17, and two fixing rods 31 are rotatably connected through the support plate 17. Three pulleys 32 are fixedly arranged on the outside of the fixing rods 31, and the pulleys 32 are adaptively matched with the storage holes 30.

[0047] The setting of the pulleys 32 is beneficial to quickly moving the support plate 17 away from the bottom of the U-shaped steel plate.

[0048] In this embodiment, the storage rack 11 is adaptively matched with the I-shaped plate 10. The bolt fastener 14 is composed of a bolt and a nut.

[0049] The storage rack 11 can slide freely outside the I-shaped plate 10, and the bolt fastener 14 can fix the storage rack 11 on the I-shaped plate 10.

[0050] In this embodiment, two anti-shake structures 8 are provided at the bottom of the mounting plate 1. The anti-shake structure 8 includes a base 33, two fixing plates 34, a plurality of movable rods 35, two second clamping blocks 36 and two connecting plates 37. The base 33 is fixedly connected to the mounting plate 1, the fixing plate 34 is fixedly connected to the base 33, the movable rod 35 is connected through the fixing plate 34, the second clamping block 36 and the connecting plate 37 are both fixedly connected to the movable rod 35, and a plurality of third springs 38 are provided between the second clamping block 36 and the fixing plate 34.

[0051] The rope 6, the anti-shake structure 8 and the grasping structure 7 can limit the position of the I-shaped plate 10, prevent the I-shaped plate 10 from shaking greatly during hoisting, which affects the handling efficiency, and can further improve the safety of hoisting.

[0052] In this embodiment, the anti-shake structure 8 further includes two thrust assemblies. The thrust assembly includes two L-shaped plates 39, an electric push rod 40 and a push plate 41. The L-shaped plate 39 is fixedly connected to the connecting plate 37. The electric push rod 40 is arranged at the bottom of the mounting plate 1, and the push plate 41 is fixedly connected to one end of the electric push rod 40.

[0053] The thrust assembly and the anti-shake structure 8 can move the second clamping block 36 away when needed, so that the restriction on the I-shaped plate 10 inside the base 33 is released, and the I-shaped plate 10 can move down for work.

[0054] In this embodiment, the third spring 38 is located outside the corresponding movable rod 35, and the positions of the push plate 41 and the L-shaped plate 39 are adaptively matched.

[0055] The push plate 41 moves under the action of the electric push rod 40 and exerts a thrust on the L-shaped plate 39.

[0056] In this embodiment, a limiting structure 9 is provided at the bottom of the fixing plate 34. The limiting structure 9 includes a bottom plate 42, an arc plate 43 and two screws 44. The bottom plate 42 is fixedly connected to the fixing plate 34, and the arc plate 43 is connected to the bottom plate 42 through two screws 44.

[0057] The limiting structure 9 and the anti-shake structure 8 can guide and limit the I-shaped plate 10 during the upward movement of the I-shaped plate 10, can guide the I-shaped plate 10 to gradually engage into the inside of the base 33, and prevent the I-shaped plate 10 from shifting and not being able to engage with the predetermined position of the base 33 due to shaking during the upward movement.

[0058] In this embodiment, the I-shaped plate 10 and the base 33 are adaptively matched, and the two arc plates 43 on the same side form an "eight" shape.

[0059] The arc plate 43 guides the I-shaped plate 10 .

[0060] It should be noted that the present invention is a lifting device for large-span steel structures. Before use, the mounting plate 1 is connected to an existing lifting machine to achieve working conditions.

[0061] The U-shaped steel plate is placed on a shelf not high from the ground, and the equipment is moved to the corresponding position of the U-shaped steel plate by a crane and then stopped. At this time, the U-shaped steel plate is below the cross plate 12 and between the two support plates 17 of the grabbing assembly. The two slide plates 13 are moved toward the middle of the cross plate 12 until the top of the support plate 17 contacts the bottom of the U-shaped steel plate and then stops. During the process, the slide plate 13 moves to apply pressure to the block 20. Since the top of the block 20 is inclined, the block 20 moves downward toward the inner side of the slot 18 under the action of pressure, and the spring 21 is compressed at the same time. When the slide plate 13 moves away from the range of the corresponding block 20, the spring 21 acts on the block 20 to rebound to the initial position, restricting the slide plate 13 that has just slid over to prevent it from retreating. The motor 4 is started to make the winding roller 5 act on the rope 6 to wind up the rope. The U-shaped steel plate 12 is moved by the I-shaped plate 10, and the I-shaped plate 10 moves with the storage rack 11 synchronously. The storage rack 11 moves with one end of the connecting arm 15, so that the other end of the connecting arm 15 moves with the slide plate 13 toward the middle of the cross plate 12. At the same time, because the slide plate 13 keeps moving toward the cross plate 12, the anti-skid pad 27 will gradually move toward the side of the U-shaped steel plate under the action of the spring 29, and finally cling to the side of the U-shaped steel plate, which has a limiting effect on the side of the U-shaped steel plate. When the rope 6 is wound, the two slide plates 13 will always move toward the middle of the cross plate 12. At the same time, the block 1 20 has a back-slip blocking effect on the slide plate 13, so the U-shaped steel plate located on the top of the support plate 17 will not be separated from the control range of the grabbing assembly, thereby improving the safety of lifting, and there is no need to worry about the U-shaped steel plate falling due to shaking when it moves up.

[0062] The I-shaped plate 10 gradually approaches the range of the arc plate 43 under the action of the rope 6 and the motor 4. Since the two arc plates 43 on the same side form an "eight" shape, they can play a good role in limiting and guiding the I-shaped plate 10, so as to prevent the I-shaped plate 10 from being unable to get stuck on the inner side of the base 33 due to the shaking of the rope 6 and the deviation from the original track.

[0063] When the I-shaped plate 10 contacts the second clamping block 36, since one end of the second clamping block 36 is also inclined like the first clamping block 20, under the action of pressure, the second clamping block 36 slides towards the inside of the fixing plate 34 and compresses the third spring 38. When the top of the I-shaped plate 10 contacts the inner top surface of the base 33, the motor 4 stops working. The third spring 38 loses the pressure restriction and acts on the second clamping block 36 to rebound to the initial position. At this time, the bottom of the I-shaped plate 10 contacts the top of the second clamping block 36 and is supported by the second clamping block 36. The position of the I-shaped plate 10 is limited, avoiding the shaking of the I-shaped plate 10 during the lifting process. Just use a crane to move the equipment for handling;

[0064] When it is necessary to put down the U-shaped steel plate, start the electric push rod 40 to act on the push plate 41 to move. The push plate 41 pushes the L-shaped plate 39 to move. The L-shaped plate 39 drives the connecting plate 37, the movable rod 35 and the second clamping block 36 to move synchronously, so that the restriction on the bottom of the I-shaped plate 10 is released. Start the motor 4 to make the rope 6 pay out. The I-shaped plate 10 moves down until the U-shaped steel plate is placed on the predetermined shelf and then stops. At the same time, make the push plate 41 return to the initial position through the electric push rod 40. Under the action of the second spring 29, the second clamping block 36 also rebounds to the initial position. Then rotate the threaded rod 23 to make the pressing plate 24 press down the first clamping block 20 until the first clamping block 20 does not affect the sliding of the sliding plate 13 and then stop. At this time, pull the sliding plate 13 towards both ends of the cross plate 12. The setting of the pulley 32 can make the support plate 17 move away from the bottom of the U-shaped steel plate more quickly. Stop until the support plate 17 leaves the bottom of the U-shaped steel plate. Then move the pressing plate 24 back to the initial position through the threaded rod 23. The first spring 21 loses the pressure and acts on the first clamping block 20 to rebound to the initial position. At this time, the placement work of the U-shaped steel plate can be completed;

[0065] In addition, the lifting equipment can not only lift U-shaped steel plates, but also lift flat steel plates, I-shaped steel plates, etc. At the same time, the number of grasping components can be increased according to needs to grasp the steel structures to be lifted.
