Description

Technical Field

[0001] The invention relates to the technical field of hoisting equipment, and in particular to a building structure hoisting device. Background Art

[0002] During the construction process, it is often necessary to hoist building structures and prefabricated parts. Generally, a rope is connected through a winder on the crane frame, and one end of the rope is connected to a hook to hoist and transport the structural parts.

[0003] Referring to a Chinese patent with patent publication number CN117208754B, a lifting device for a special-shaped building structure is disclosed, including a lifting frame, a lifting bar, a lifting rope group, a counterweight block and an adjustment component. The lifting bar is connected to the lifting frame through two lifting ropes. One end of the two lifting ropes can be retracted and set on the lifting frame, and the other end is set on the lifting bar. A hook is set at the bottom of the lifting bar, and the hook is used to lift the special-shaped building structure.

[0004] In the prior art, after a large number of structural parts are transported to the construction site, they may be randomly stacked, and then they are lifted from one end of the structural parts and sent to a high place. Often, the structural parts are fixed with one side facing the delivery area, which is especially important for large plate structural parts. It is not convenient to directly turn or flip them before delivery or lifting. Generally, the crane needs to be moved to achieve the turning, but this method requires a large moving space, or the lifting device needs to be re-fixed after the mobile crane frame is deflected during the lifting process to change the direction of the structural parts, which is troublesome and affects work efficiency, or the structural parts need to be manually flipped in the lifting state during the delivery process, which is laborious and prone to safety hazards due to the torque of the rope. Therefore, the lifting equipment commonly used in the prior art cannot effectively and conveniently deflect or flip large structural parts. Summary of the invention

[0020] In the present invention, reference is made to Figure 1-Figure 2 , the frame 1 is tilted downward in a direction away from the driving motor 7, an electric push rod 9 corresponding to the horizontal position of the deflection member 8 is fixed in the frame 1, a limit plate 10 is fixed to one end of the electric push rod 9 facing the deflection member 8, the limit plate 10 is located on one side of the deflection member 8, both ends of the deflection member 8 are provided with movable notches 12, the top and bottom of the movable notches 12 are penetrated, the rope 6 moves in the movable notch 12, so that in a normal state, as Figure 2 As shown, the deflection member 8 is placed horizontally, so that the deflection member 8, the pulley 1 2, the pulley 2 3 and the pulley 3 4 are on the same vertical plane, and the rope 6 is naturally extended and moved. At this time, when the electric push rod 9 is in the process of extending and retracting the limit plate 10, the outer wall of the limit plate 10 is in sliding contact with the side wall of the deflection member 8, so that the rope 6 is limited by the movable notch 12 on the deflection member 8 to ensure the stability of the rope 6 during normal lifting; When the deflection member 8 is rotated by the driving motor 7 to adjust the deflection angle of the pulley 3 4 and the hook 5, the deflection member 8 is rotated toward the end of the electric push rod 9 toward the limit plate 10; Figure 3 As shown, Figure 3 The first use state shown is that when the deflection angle of the deflection member 8 is between 0 and 45 degrees, the bending amplitude of the rope 6 is small and its resilience is small. At this time, during the deflection process, the electric push rod 9 is used to retract the limit plate 10 without affecting the rotation of the deflection member 8, and after the deflection is completed, the limit plate 10 is squeezed with the end of the deflection member 8 to improve the positioning stability of the deflection member 8 and reduce the load on the output shaft of the drive motor 7. After the deflection amplitude is large, Figure 4 As shown, Figure 4 The second use state shown is when the deflection angle of the deflection member 8 is between 45° and 90°, and when the deflection angle exceeds 90°. Figure 5 As shown, Figure 5 The third use state shown refers to the process in which the deflection angle of the deflection member 8 is greater than 90°, and the resilience of the bending of the rope 6 gradually increases. At this time, during the deflection process, the electric push rod 9 can extend the limit plate 10 to make the side of the limit plate 10 slide and contact with the side wall of the deflection member 8, so as to use the limit plate 10 to assist the deflection of the deflection member 8 and assist in limiting to ensure the stability of the deflection member 8 during the deflection process, and to increase the load on the drive motor 7 after the deflection; after the deflection is 180 degrees, the extended electric push rod 9 and the limit plate 10 can be used to limit the contact with the deflection member 8; Thus, through the position distribution setting of pulley 1 2, pulley 2 3 and pulley 3 4, and the movement coordination of the deflection member 8 and the limit plate 10, the pulley 3 4 and the hook 5 can carry the deflection or flipping operation of the structural member, and effectively improve the stability during the deflection process and after the deflection, and avoid the safety hazard caused by swinging due to damage to the equipment, thereby effectively improving the work efficiency of the lifting operation.

[0021] In the present invention, reference is made to Figure 1-Figure 8 , both sides of the movable notch 12 are provided with a penetrating slide groove 13, and a slider 14 is limitedly slidable in the slide groove 13, and the top and bottom of the slider 14 are provided with a limit groove, and the top and bottom inner walls of the slide groove 13 are fixed with a limit strip 17, and the limit strip 17 is in sliding contact with the limit groove, and a through hole is provided at the end of the slider 14, and a limit rod 15 is rotatably connected between the two sliders 14, and a spring 16 is connected between the side wall of the slider 14 away from the drive motor 7 and the inner wall of the slide groove 13, and the rope 6 is arranged at a side position of the limit rod 15 away from the spring 16. Under normal conditions, the spring 16 is compressed by using the stretched rope 6. When the rope 6 bends as the deflection member 8 rotates, the ropes 6 on both sides of the deflection member 8 will move closer to the middle, and the slider 14 moves closer toward the center position of the deflection member 8, so as to use the pressure of the spring 16 to assist in offsetting the rebound force of the rope 6 to assist in stabilizing the rope 6 and further assist in reducing the load of the drive motor 7.

[0022] In the present invention, reference is made to Figure 1-Figure 7A cover cylinder 11 is fixed to the outer wall of the driving motor 7, and the outer wall of the cover cylinder 11 is set to a circumferential surface. A plurality of penetrating grooves are opened on the outer wall of the cover cylinder 11. In the process of ensuring normal heat dissipation of the driving motor 7, the ropes 6 on both sides of the deflection member 8 contact the outer wall of the cover cylinder 11 during bending. The circumferential surface of the outer wall of the cover cylinder 11 is used to avoid direct friction contact between the ropes 6 and the edges and corners of the outer wall of the driving motor 7, thereby ensuring the effectiveness and stability of the use of the ropes 6.

[0023] In the present invention, reference is made to Figure 1-Figure 8 A mounting frame 501 is fixed to the top of the hook 5, and the pulley three 4 is rotatably connected to the mounting frame 501 through a bearing. A baffle one is provided at the bottom end of the outer wall of the pulley three 4. While the pulley three 4 is used to limit the rope 6, the rotation setting of the pulley three 4 is utilized to reduce the wear of the rope 6 during the movement.

[0024] Embodiment 2: Embodiment 2 includes all structures and methods of Embodiment 1, with reference to Figure 1-Figure 9 , a building structure hoisting device also includes, pulley 1 2 is arranged on the side of the driving motor 7 close to the electric push rod 9, pulley 2 3 is arranged on the side of the driving motor 7 away from the electric push rod 9, a fixing rod 18 is installed at a position corresponding to the pulley 1 2 on the frame 1, the pulley 1 2 is fixedly connected to the fixing rod 18, a fixing rod 2 19 is installed at a position corresponding to the pulley 2 3 on the frame 1, the pulley 2 3 and the fixing rod 2 19 are limitedly slidable, an auxiliary groove is arranged on the outer wall of the fixing rod 2 19, and an auxiliary block is arranged on the inner wall of the pulley 2 3 at a position corresponding to the auxiliary groove, so that the pulley 2 3 can slide horizontally outside the fixing rod 2 19, and during the rotation and deflection process of the deflection member 8, the pulley 2 3 will move to the edge position along the fixing rod 2 19 due to the movement of the rope 6 to cooperate with the deflection of the rope 6, thereby avoiding excessive bending of the rope 6, reducing the wear of the rope 6 and improving the stability of the movement of the rope 6 after deflection.

[0025] In the present invention, reference is made to Figure 1-Figure 10 A telescopic rod fixed to the limit plate 10 is provided in the electric push rod 9, and a sliding sleeve 20 is slidably connected to the outer wall of the telescopic rod. Connecting rods 21 are fixed on both sides of the sliding sleeve 20, and a connecting plate 22 is fixed between the end of the connecting rod 21 and the frame 1. Therefore, when the electric push rod 9 controls the limit plate 10 to move horizontally, the telescopic rod of the electric push rod 9 moves horizontally in the sliding sleeve 20. When the limit plate 10 limits the deflection member 8, the deflection member 8 will be dispersed at the position of the limit plate 10 due to the rebound force of the rope 6, and part of the rebound force will be dispersed to the positions of the connecting rod 21 and the connecting plate 22, thereby further improving the stability of the deflection member 8 and the rope 6 after deflection, and reducing the load of the drive motor 7.
