[0002] The hanging frame for building construction projects refers to an important piece of equipment used on construction sites for hoisting and transporting building materials, equipment, tools, etc. It can help workers efficiently lift heavy objects and transfer them to designated positions, thereby simplifying the construction process and improving work efficiency. The construction hanging frame usually consists of a hook, a suspension rope, a suspension rod, etc., and according to actual construction needs, auxiliary equipment such as a hanging basket and a hanging basket motor can be equipped. In the prior art, during the use of traditional devices, affected by the weight distribution factor of the loaded items, if the loaded items are irregularly shaped, it is very difficult to ensure that the center of gravity is located at the center of the hanging frame, resulting in the inclination of the hanging frame. The inclination of the hanging frame greatly affects the stability of hoisting and reduces safety.

[0003] For example, a device for hoisting building materials used in building construction disclosed in the authorized patent document with the application number CN201910285446.6 includes a hanging frame and a hanging plate frame, and is characterized in that: the hanging frame includes a hanging plate, four suspension ropes, and a hook. The hanging plate is a circular steel plate, and a hook is provided at the center of the upper surface of the circular steel plate. Four suspension ropes are equidistantly arranged on the circumference of the lower surface of the circular steel plate. The hanging plate frame is a steel frame, which includes two rectangular fixing plates, two sliding plates, and four columns. Among them: the free ends of the four suspension ropes are respectively fixed to the two sliding plates on both sides of the two sliding plates after passing through the corresponding pulley mechanisms and through holes on the upper fixing plate, so that the two sliding plates perform opening and closing actions with the tightening and loosening of the suspension ropes to clamp or loosen the hoisted building materials.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a safe construction hanger for building construction projects, including: a hoist 40 and a hanging plate 9; Two U-shaped plates 1 are provided at the bottom of the hanging plate 9. Two support rods 43 with hole parts are integrally processed at the top of the two U-shaped plates 1, and a base 4 is fixedly installed at the bottom of the two U-shaped plates 1; A winding mechanism 11 is provided on the surface of the U-shaped plate 1. The winding mechanism 11 includes two mounting brackets 32 fixedly installed on the surface of the U-shaped plate 1. The hoist 40 is used to lift the base 4. Four suspension ropes 10 are fixedly installed at the bottom of the suspension plate 9. Motors 33 are fixedly installed on the surfaces of both mounting brackets 32. A winding roller 34 is installed at the output end of the motor 33. The lower ends of the suspension ropes 10 are fixedly installed on the surface of the winding roller 34. The four winding rollers 34 are respectively used to wind the four suspension ropes 10; Specifically, through the setting of the reduction gear mechanism 2, the rapid falling and stopping of the U-shaped plate 1 can be realized. Then, by the combined setting of the rotating rollers 3, the panel 5, the closing door mechanism 8 and the first locking mechanism 12, when unloading is required, the U-shaped plate 1 can tilt to the designated side, and at the same time, the closing door automatically opens, so that the loaded goods slide out of the device, completing the automatic unloading of the device; by the combined setting of the winding mechanism 11 and the leakage groove 7, the U-shaped plate 1 can shake up and down, and the rotating rollers 3 rotate for conveying, ensuring that the loaded goods are completely removed, and the impurities on the panel 5 will fall on the U-shaped plate 1 and finally flow out along the upper surface of the inner bottom wall of the U-shaped plate 1, completing the automatic removal of impurities.

[0021] The top of the base 4 is provided with a panel 5 through a plurality of return springs 38. A plurality of grooves 6 are opened at the top of the panel 5. Rotating rollers 3 are rotatably installed inside the plurality of grooves 6. are fixedly installed on the surfaces of the plurality of rotating rollers 3. Leakage grooves 7 are provided at the bottoms of the plurality of grooves 6. Rotating drive mechanisms 41 are installed on the surfaces of the plurality of rotating rollers 3. First chutes 42 are opened on both sides of the groove 6. A one-way rack 44 is clamped in the first chute 42 through an electric spring 45. A gear 39 meshing with the one-way rack 44 is fixedly installed on the surface of the rotating roller 3; In this embodiment, the U-shaped plate 1 is continuously shaken up and down. The lifting and lowering movement of the base 4 causes the panel 5 to shake up and down. The one-way rack 44 will drive the gear 39 to drive the rotating roller 3 to rotate intermittently, and convey the loaded goods towards the pre-unloading port, ensuring that the loaded goods are removed from the device.

[0022] Second chutes 46 are provided at the bottoms of the plurality of first chutes 42. A first electrode block 47 and a second electrode block 48 are arranged inside the second chutes 46; A piston chamber 14 is provided in each of the four convex portions at the bottom of the base 4. A piston body 15 is provided inside each of the four piston chambers 14. The surface of the piston body 15 is in close fit with the inner wall of the piston chamber 14. A support rod 17 is fixedly installed at the bottom of the piston body 15. A runner 18 is provided at the bottom of the support rod 17. And a solenoid valve 21 is provided at the top of the piston chamber 14. A guide groove 23 is provided on the surface of the U-shaped plate 1. A guide block 24 is provided inside the guide groove 23. And a cylinder block 22 is provided at the top of the guide block 24. The solenoid valve 21 is communicated with the cylinder block 22; Further, when the hoist 40 is about to stop transporting the U-shaped plate 1, the hoist 40 controls the U-shaped plate 1 to move along the transport direction and descend. When the runner 18 contacts the ground, it starts to rotate. At this time, the rotating shaft 16 and the runner 18 rotate relative to each other. Through the cooperative setting of the internal gear ring 19 and the elastic piece 20, the tooth grooves of the internal gear ring 19 continuously push the elastic piece 20, thereby realizing buffering, enabling the U-shaped plate 1 to be quickly stabilized, and realizing the quick stop of the U-shaped plate 1.

[0023] A speed reduction wheel mechanism 2 is provided at the bottom of the base 4. The speed reduction wheel mechanism 2 includes a rotating shaft 16 provided inside the runner 18. An internal gear ring 19 is fixedly installed inside the runner 18. An elastic piece 20 is fixedly installed on the surface of the rotating shaft 16. The elastic piece 20 is used in cooperation with the internal gear ring 19. The rotating shaft 16 and the runner 18 rotate relative to each other; It should be noted that during the process of the hoist 40 controlling the U-shaped plate 1 to move along the transport direction and descend, since the piston chamber 14 stores hydraulic oil and the piston 15 can slide inside the piston chamber 14, the runner 18 can be slightly retracted into the piston chamber 14. That is, when the U-shaped plate 1 drives the runner 18 to fall, the collision force between the runner 18 and the ground can be buffered.

[0024] Two second locking mechanisms 13 are provided on the surfaces of the two U-shaped plates 1. The second locking mechanism 13 includes a second one-way ratchet 35 fixedly installed at one end of a winding roller 34. A second positioning ring 37 is fixedly installed on the surface of the U-shaped plate 1. A second locking rod 36 is slidably installed inside the second positioning ring 37. One end of the second locking rod 36 is in an inclined shape. The end of the second locking rod 36 with a linear and planar shape is engaged with the surface of the second one-way ratchet 35. And a first locking rod 27 is fixedly installed at the bottom of the second locking rod 36; It is worth noting that after the closing door 25 rotates and opens, the closing door 25 will rotate to the end away from the first one-way ratchet 26 and fit with the ground. And at this time, the closing door 25 is in an inclined state, which is beneficial to the stable discharge of the loaded goods.

[0025] Such as Figure 7 and Figure 9As shown in the figure, it should be noted that during the hoisting process, the second locking rod 36 and the second one-way ratchet 35 are in an engaged state, which avoids the reverse rotation of the winding roller 34 under the influence of the pulling force of the hoisting rope 10 during the hoisting process, causing the hoisting rope 10 to unwind, thereby improving safety and preventing damage to the motor 33 due to the long-term application of a large torque on the output end of the motor 33 during the hoisting process; When the first locking rod 27 moves away from the first one-way ratchet 26, the second locking rod 36 follows the first locking rod 27 and moves away from the second one-way ratchet 35. The second locking rod 36 disengages from the second one-way ratchet 35. At this time, the motor 33 near the pre-unloading opening is started, and the motor 33 drives the winding roller 34 to rotate forward and backward slightly, causing the hoisting rope 10 to continuously unwind and wind slightly.

[0026] Both surfaces of the two U-shaped plates 1 are provided with two first locking mechanisms 12. The first locking mechanism 12 includes a first positioning ring 30 fixedly installed on the surface of the U-shaped plate 1. The inside of the first positioning ring 30 is slidably installed on the surface of the first locking rod 27. One end of the first locking rod 27 is beveled. A protrusion 29 is fixedly installed on the surface of the first locking rod 27. An inclined slide rail 28 is provided on the surface of the U-shaped plate 1. The inclined slide rail 28 is used in cooperation with the protrusion 29. The inclined slide rail 28 is arranged in the second chute 46.

[0027] It further includes a closing door mechanism 8. The closing door mechanism 8 includes a closing door body 25 rotatably installed on both sides of the base 4. The closing door body 25 is rotatably installed between the two U-shaped plates 1. First one-way ratchets 26 are fixedly installed on both sides of the closing door body 25. The axis of the first one-way ratchet 26 is coaxially arranged with the axis of the rotating shaft 16 of the closing door body 25; It should be noted that when unloading is required, first select one of the openings of the U-shaped plate 1 as the pre-unloading opening according to the unloading location, and open the two solenoid valves 21 adjacent to the pre-unloading opening. Affected by the gravity of the U-shaped plate 1 and the panel 5, etc., the two rotating wheels 18 corresponding to the pre-unloading opening are retracted into the piston chamber 14 (when the solenoid valve 21 is opened, the descending position of the steel wire rope on the hoist 40 must ensure that the hoisting rope 10 is in a slack state, so that the base 4 can descend and the rotating wheel 18 can be retracted into the piston chamber 14), causing a part of the U-shaped plate 1 near the pre-unloading opening to tilt downward; at the same time, the piston 15 squeezes the hydraulic oil in the piston chamber 14 and injects it into the cylinder body 22. The telescopic end of the cylinder body 22 extends and abuts against the guide block 24 to move downward along the guide groove 23, driving the panel 5 to move downward. The rotating roller 3 extends out of the groove 6. At this time, the panel 5 no longer supports the load, and only the rotating roller 3 supports the load; When the panel 5 descends, the inclined slide rail 28 follows and descends. Then, by the cooperative setting of the protrusion 29 and the first positioning ring 30, the first locking rod 27 moves away from the first one-way ratchet 26, and the first locking rod 27 disengages from the first one-way ratchet 26, thereby releasing the limit on the first one-way ratchet 26; as Figure 2 shown, since a part of the U-shaped plate 1 near one end of the pre-unloading opening is inclined downward at this time, affected by the gravity of the weight block 31, the closing door 25 near the pre-unloading opening automatically rotates to a position away from the center of the U-shaped plate 1, the closing door 25 opens, and affected by gravity, the loaded goods slide on the rotating roller 3 towards the pre-unloading opening and finally move out of the device, completing the automatic unloading of the device.

[0028] On one adjacent side of each of the two U-shaped plates 1, a convex block for restricting the rotation range of the closing door body 25 is fixedly installed.

[0029] On the top of the opposite sides of the two closing door bodies 25, weight blocks 31 are fixedly installed.

[0030] Influenced by the weight distribution factor of the loaded goods, when the U-shaped plate 1 tilts to one side, the corresponding motor 33 is controlled to start, the winding roller 34 rotates and the lifting rope 10 is retracted, thereby straightening the U-shaped plate 1 and ensuring the stability of the hoist 40 during the lifting of the U-shaped plate 1. When the transportation of the U-shaped plate 1 by the hoist 40 is about to stop, the hoist 40 controls the U-shaped plate 1 to descend while moving along the transportation direction. When the runner 18 contacts the ground and starts to rotate, at this time, the rotating shaft 16 and the runner 18 rotate relative to each other. Through the cooperative setting of the internal gear ring 19 and the elastic piece 20, the tooth grooves of the internal gear ring 19 continuously push the elastic piece 20, thereby realizing buffering and enabling the U-shaped plate 1 to stop quickly and stably, achieving the quick stop of the U-shaped plate 1; When unloading is required, first select one of the openings of the U-shaped plate 1 as the pre-unloading opening according to the unloading location, and open the two solenoid valves 21 adjacent to the pre-unloading opening. Affected by the gravity of the U-shaped plate 1, the panel 5, etc., the two runners 18 corresponding to the pre-unloading opening are retracted into the piston chamber 14 (when the solenoid valve 21 is opened, the descending position of the steel wire rope on the hoist 40 must ensure that the lifting rope 10 is in a slack state, so that the base 4 can descend and the runner 18 can be retracted into the piston chamber 14), making a part of the U-shaped plate 1 near the pre-unloading opening inclined downward; at the same time, the piston 15 squeezes the hydraulic oil in the piston chamber 14 and injects it into the cylinder block 22, and the telescopic end of the cylinder block 22 extends and abuts against the guide block 24 to move downward along the guide groove 23, driving the panel 5 to move downward, and the rotating roller 3 extends out of the groove 6. At this time, the panel 5 no longer supports the loaded goods, and only the rotating roller 3 supports the loaded goods.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
