Description

Technical Field

[0001] The utility model relates to the technical field of construction machinery, in particular to a construction engineering hoisting structure. Background Art

[0002] The hoisting structure in construction projects refers to a temporary or permanent structural system used to lift, transport and install various building components (such as steel beams, steel columns, precast concrete components, etc.) during the construction process to form a construction method for the overall building structure. It is widely used in bridges, high-rise buildings, large factories and other projects to improve construction efficiency and safety.

[0003] At present, the existing construction project hoisting structure is unable to effectively restrict and stabilize the hoisted objects, resulting in insufficient safety and stability of the hoisted objects during the hoisting process. The objects are easily affected by external forces and fall, which increases the risk and uncertainty of the hoisting operation. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing technology that the hoisted objects cannot be effectively restricted, are easily affected by external forces and fall, and increase the risk and uncertainty of the hoisting operation, and to propose a construction engineering hoisting structure.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A construction engineering hoisting structure, comprising:

[0007] A movable base, wherein a rotating base is rotatably provided on the top of the movable base, a pedestal is fixedly provided on the top of the rotating base, a support arm is hingedly provided on the top of the pedestal, and an extension arm is embedded and slidably provided at the front end of the support arm;

[0008] A lifting assembly is provided on the pedestal and is used for lifting construction items;

[0009] The limiting mechanism is arranged on the hoisting assembly and is used to limit the hoisted items.

[0010] In one possible design, the lifting assembly includes two fixed frames symmetrically fixed on one side of the pedestal, a drum is rotatably provided on the side close to the two fixed frames, a cable is wound around the outside of the drum, a motor is fixedly provided on one side of the fixed frame, and one end of the motor output shaft is fixedly connected to the drum.

[0011] In one possible design, the limiting mechanism includes a hanging ring detachably provided at one end of the cable, a lifting hook detachably provided inside the hanging ring, a baffle rotatably provided at the opening of the lifting hook, a connecting frame fixedly provided on one side of the baffle and the lifting hook, the inner sides of the two connecting frames are hooked with the same tension spring, the cable is rotatably provided above the lifting hook, ropes are fixedly provided on both sides of the counterweight, and hooks are fixedly provided at one end of the two ropes, and the two hooks can be detached from the hooks and hung on both sides of the counterweight.

[0012] In one possible design, a hydraulic cylinder is hingedly provided on one side of the top of the pedestal, the output end of the hydraulic cylinder is hinged to the support arm, an electric push rod is hingedly provided on the bottom of the support arm, and the output end of the electric push rod is hinged to the extension arm.

[0013] In a possible design, support rods are symmetrically rotatably provided on both sides of the movable base, connecting rods are slidably provided at one end of the four support rods, threaded rods are threadedly connected to one end of the four connecting rods, hand wheels are fixedly provided at the top ends of the four threaded rods, and support pads are rotatably provided at the bottom ends of the four threaded rods.

[0014] In a possible design, a No. 1 pulley for setting up the cable is fixedly provided on the top of the pedestal and the support arm, and a No. 2 pulley for setting up the cable is rotatably provided on the front end of the extension arm.

[0015] In this application, when starting to use, first move the device to the position where it needs to be used through the movable base, then unfold the four support rods on both sides of the movable base, then pull out the connecting rod from one end of the support rod, and then turn the hand wheel. While the hand wheel rotates, it drives the threaded rod and the support pad closer to the ground until the support pad touches the ground, completing the overall support of the device;

[0016] Then install the object to be hoisted on the rope, and then hook the rope of the installed object on it through the opening of the hoisting hook. When the rope is hooked on the hoisting hook, the rope presses the baffle to expand. At this time, the tension spring is deformed under force. When the baffle expands, the rope falls into the hoisting hook. After the rope falls in, the tension spring pulls the baffle to return to its original position through its own elastic principle. After the baffle is reset, it presses against one side of the hoisting hook, so that the opening of the hoisting hook is blocked to prevent the hoisted object from falling. Then remove the two hooks from both sides of the counterweight block, and then hook the two hooks on both sides of the hoisted object to assist in fixing the object, which can prevent the object from tilting during the hoisting process, resulting in unbalanced weight and causing the object to fall.

[0017] Then start the motor, the motor output shaft rotates to drive the drum to rotate, and when the drum rotates, the cable is gradually tightened to lift the hoisted items off the ground, and the pulley group (pulley 1 and pulley 2) is used to guide and support the cable to ensure a smooth hoisting process. When the counterweight rises to a certain position, the output shaft of the servo motor rotates, and the servo motor output shaft rotates while driving the bidirectional screw to rotate. The bidirectional screw rotates while driving the two clamping frames to move to the side close to each other, so that the two clamping frames clamp the counterweight, thereby further fixing the hoisted items to prevent the items from shaking and falling. Then the output end of the hydraulic cylinder extends to push the support arm. The fan-shaped angle opens and extends upward. At the same time, the output end of the electric push rod can be synchronously extended to push the extension arm out of the support arm, thereby driving the hoisted objects to rise in height and adjusting the height of the hoisted objects. Then, by rotating the rotating base, the direction of the pedestal and the hoisted objects on it can be adjusted to achieve precise control of the position of the hoisted objects. Through the coordinated work of the rotating base, hydraulic cylinder and electric push rod, the construction objects can be transported to the designated position and their position can be precisely adjusted. When it reaches the designated position, start the motor again, relax the cable, put the objects down, and then press the baffle to remove the rope from the opening of the hoisting hook to complete the hoisting operation.

[0018] The utility model has the following beneficial effects:

[0019] The utility model adopts the arrangement of the hoisting assembly and the motor drives the drum to rotate to flexibly control the tightening and loosening of the cable, so that the hoisted objects can be lifted off the ground smoothly and placed accurately in the designated position, thus realizing the efficient and safe hoisting operation of the building objects.

[0020] The utility model effectively enhances the safety and stability of the hoisted objects during the hoisting process by setting the limiting mechanism, prevents the hoisted objects from falling due to external forces, and ensures the safe and smooth progress of the hoisting operation.

[0021] The utility model combines the limiting mechanism with the clamping frame and other components, which not only ensures the stability and safety of the hoisted objects during the lifting process and prevents accidental falling, but also realizes efficient and precise control of the hoisting operation, greatly improving the reliability and operational convenience of the hoisting operation.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Example 1

[0031] Reference Figure 1-5 , a hoisting structure, comprising:

[0032] The movable base 1 is designed with wheels or other moving mechanisms to facilitate flexible movement at the construction site. A towing frame is fixedly installed on the front side of the movable base 1 to facilitate the movement of the entire device. A driving motor is embedded in the top of the movable base 1. A rotating base 2 is rotatably arranged above the driving motor on the top of the movable base 1. The output shaft of the driving motor is fixedly connected to the rotating base 2, so that the rotating base 2 can rotate 360 degrees, thereby providing a full range of lifting operation angles. A pedestal 3 is fixedly installed on the top of the rotating base 2 as the installation base for the lifting assembly and the support arm 4.

[0033] A support arm 4 is hingedly provided at the top of the pedestal 3, and the support arm 4 can be fanned out with the pedestal 3 as the center to increase the height and range of the lifting. An extension arm 5 is embedded and slidably provided at the front end of the support arm 4, and the extension arm 5 can be extended from the inside of the support arm 4 to further expand the coverage of the lifting operation.

[0034] A frame 501 is installed at the bottom of the extension arm 5. Two clamping frames 502 that can clamp and fix the counterweight 901 are slidably installed inside the frame 501. A two-way screw rod 503 is also rotatably provided on the inner side of the frame 501. The two clamping frames 502 are respectively threadedly connected to the two ends of the two-way screw rod 503. A servo motor 504 is installed on the outer side of the frame 501, and its output shaft is connected to the two-way screw rod 503. An infrared sensor (model: HC-SR501) is embedded and installed on the side where the two clamping frames 502 are close to each other. When the counterweight 901 rises to a predetermined range, the infrared sensor receives a signal and transmits the signal to the controller, which controls the motor through the controller. 8 reduces the rotation speed and slows down the rising speed. After rising to the predetermined height, the infrared sensor receives the signal and transmits the signal to the controller respectively. The controller controls the servo motor 504 and the motor 8. At this time, the motor 8 stops driving the cable 9 to rotate and retract, and the output shaft of the servo motor 504 starts to rotate. The output shaft of the servo motor 504 drives the bidirectional screw rod 503 to rotate while the output shaft rotates. While the bidirectional screw rod 503 rotates, its two ends respectively drive the two clamping frames 502 to move toward the side close to each other, so that the two clamping frames 502 clamp the counterweight block 901, thereby further fixing the hoisted items, and can work together with the limiting mechanism to fix and limit the hoisted items.

[0035] The lifting assembly is arranged on one side of the base 3, and two fixing frames 6 are symmetrically fixed. The same reel 7 is rotatably installed between the two fixing frames 6. A cable 9 is wound around the outside of the reel 7 for lifting objects. A motor 8 is fixedly installed on one side of the fixing frame 6. The output shaft of the motor 8 is fixedly connected to the reel 7. By starting the motor 8, the reel 7 can be driven to rotate, thereby tightening or loosening the cable 9 to realize the lifting and unloading of objects.

[0036] The setting of the limiting mechanism ensures the safety of the hoisted objects, which includes a ring at one end of the cable 9 and a detachable hanging ring 1001 (the hanging ring 1001 includes a ring and a bolt such as Figure 4As shown, the ring is threadedly connected to the bolt. The ring can be removed by unscrewing the bolt from the ring, and then the ring is threaded with the circular ring on the cable 9 and the lifting hook 10, and then the bolt is screwed on the ring to complete the connection between the cable 9 and the lifting hook 10). For the installation of the lifting hook 10, a lifting hook 10 is detachably provided inside the hanging ring 1001 for hooking objects. The lifting hook 10 can be rotated on the hanging ring 1001. A baffle 11 is rotatably provided at the opening of the lifting hook 10. When the lifting hook 10 hooks an object, the baffle 11 will be rotated and opened by the pressure of the cable 9 or the object. At this time, the tension spring 13 connected to the baffle 11 and the connecting frame 12 on one side of the lifting hook 10 will be deformed. When the object falls completely into the lifting hook 10, the tension spring 13 uses its own elastic principle to pull the baffle 11 The detachable hanging ring 1001 is provided between the cable 9 and the lifting hook 10, so that the components required for the hooking can be replaced according to actual needs, thereby increasing its adaptability.

[0037] In order to adjust the lifting height, a hydraulic cylinder 14 is hingedly provided on one side of the top of the pedestal 3, and the output end of the hydraulic cylinder 14 is hinged to the support arm 4. By controlling the extension and contraction of the hydraulic cylinder 14, the support arm 4 can be pushed to expand at a fan-shaped angle and extend upward. At the same time, an electric push rod 15 is hingedly provided at the bottom of the support arm 4, and the output end of the electric push rod 15 is hinged to the extension arm 5. By controlling the extension and contraction of the electric push rod 15, the extension arm 5 can be pushed out from the support arm 4 to further adjust the lifting height.

[0038] The present application can be used in the technical field of hoisting structures in construction engineering, and can also be used in other fields applicable to the present application.

[0039] Example 2

[0040] On the basis of Example 1, Example 2 also includes: a construction engineering hoisting structure, which is applied to the technical field of construction engineering hoisting structures. In addition, in order to increase the stability of the device, four support rods 18 are symmetrically arranged on both sides of the movable base 1. One end of the four support rods 18 is slidably provided with a connecting rod 19, and one end of the connecting rod 19 is threadedly connected to a threaded rod 20. By rotating the hand wheel 21, the threaded rod 20 can be driven up and down, thereby driving the support pad 22 to contact the ground and firmly support the entire device.

[0041] The top of the pedestal 3 and the support arm 4 are fixedly provided with a No. 1 pulley 16 for laying the cable 9, and the front end of the extension arm 5 is rotatably provided with a No. 2 pulley 17 for laying the cable 9. The No. 1 pulley 16 and the No. 2 pulley 17 can guide and support the cable 9 to ensure a smooth lifting process.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 8, hydraulic cylinder 14 and electric push rod 15 are commonplace, and the operation of the controller controlling the components are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selection according to their needs or convenience.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
