Description

Technical Field

[0001] The utility model relates to the technical field of hoisting equipment, in particular to a construction hoisting equipment. Background Technique

[0002] During the process of engineering construction, it is often necessary to hoist building materials for easy installation, especially the hoisting of plates. Therefore, during the hoisting of plates, hoisting equipment is required.

[0003] Currently, in the prior art, the Chinese patent with the publication number of CN219652508U discloses a construction hoisting equipment. This device can effectively fix and clamp building materials through the mutual cooperation between structures such as a third motor, clamping plates, threaded sleeves, bidirectional threaded rods, and mounting plates. The clamping effect is relatively high, which improves work efficiency and is convenient for people to use. However, during the actual use of this device, although the clamping plates can clamp building materials, during the hoisting process, the pulling rope will shake after being affected by the wind, and then the clamping plates will shake. During this process, the building materials may fall off. In view of this, we propose a construction hoisting equipment. Summary of the Utility Model

[0027] Please refer to Figures 1 - 3 , the present utility model provides a construction hoisting device, which includes a base 1. An electric telescopic column 2 is fixedly connected to the upper side of the base 1. A reinforcing frame 3 is fixedly connected to the outer wall of the base 1. A winding roller 4 is rotatably connected to the inner surface of the reinforcing frame 3. A motor is fixedly connected to the outer wall of the reinforcing frame 3, and the output shaft of the motor is fixedly connected to the winding roller 4. By rotating the output shaft of the motor, the winding roller 4 can be driven to rotate, thereby realizing the unwinding and winding of the pulling rope 5. The pulling rope 5 is wound around the winding roller 4. One end of the pulling rope 5 away from the winding roller 4 is fixedly connected to a hoisting device 6. By using the hoisting device 6, the board can be hoisted and the dropping of the board can be prevented at the same time.

[0028] In an embodiment of the present utility model, in order to be able to hoist a plate, specifically, the hoisting device 6 includes a fixed seat 61. A stepping motor 62 is fixedly connected to the outer wall of the fixed seat 61. A bidirectional lead screw 63 is fixedly connected to the output shaft of the stepping motor 62. The bidirectional lead screw 63 is threadedly connected to a threaded block 64. A groove is formed in the lower side of the fixed seat 61, and the threaded block 64 is slidably connected in the groove. One end of the bidirectional lead screw 63 away from the stepping motor 62 is rotatably connected in the groove. A fixing plate 65 is fixedly connected to the lower side of the threaded block 64. An anti-detachment assembly 66 is arranged in the fixing plate 65. By rotating the output shaft of the stepping motor 62, the bidirectional lead screw 63 can be driven to rotate. Under the limiting action of the groove on the threaded block 64, the threaded block 64 moves stably, driving the fixing plate 65 to fix the plate, facilitating subsequent hoisting work.

[0029] Furthermore, in order to prevent the hoisted plate from detaching, specifically, a notch 651 is formed in the outer wall of the fixing plate 65. The anti-detachment assembly 66 includes a sliding block 661. The sliding block 661 is slidably connected in the inner wall of the fixing plate 65. The sliding block 661 and the inner wall of the fixing plate 65 are elastically connected by a return spring. A connecting rod 662 is fixedly connected to the side of the sliding block 661 away from the return spring. A pressing plate 663 is fixedly connected to the end of the connecting rod 662 away from the connecting rod 662. A fixed block 667 is fixedly connected to the inner wall of the fixing plate 65. The fixed block 667 is penetrated by a wedge-shaped rod 666 and is slidably connected to the wedge-shaped rod 666. A sliding plate 665 is fixedly connected to the wedge-shaped rod 666. The sliding plate 665 and the fixed block 667 are elastically connected by a connecting spring. An inclined rod 664 is hinged to the side of the sliding plate 665 away from the wedge-shaped rod 666. A straight groove is formed in the outer wall of the inclined rod 664, and a positioning rod is slidably connected in the straight groove. During the process of the fixing plate 65 fixing the plate, the plate presses the pressing plate 663. At this time, the pressing plate 663 moves towards the notch 651. The connecting rod 662 drives the sliding block 661 to compress the return spring, causing the sliding block 661 to press the inclined rod 664, driving the inclined rod 664 to rotate. Further, the sliding plate 665 compresses the connecting spring, causing the wedge-shaped rod 666 to extend, supporting the bottom of the plate, preventing the plate from detaching, and ensuring the safety of the use of the device.

[0030] During use, first start the motor. The output shaft of the motor rotates to drive the winding roller 4 to unwind the pulling rope 5, lowering the hoisting device 6. Then start the stepping motor 62. The output shaft of the stepping motor 62 rotates, which can drive the bidirectional lead screw 63 to rotate. Under the limiting effect of the groove on the threaded block 64, the threaded block 64 moves stably, driving the fixing plate 65 to fix the plate. During this process, the plate presses the pressing plate 663. At this time, the pressing plate 663 moves towards the notch 651. The connecting rod 662 drives the sliding block 661 to compress the return spring, causing the sliding block 661 to press the inclined rod 664, driving the inclined rod 664 to rotate. Furthermore, the sliding plate 665 compresses the connecting spring, making the wedge-shaped rod 666 extend to support the bottom of the plate. Then start the motor again. The output shaft of the motor rotates to drive the winding roller 4 to wind the pulling rope 5, raising the hoisting device 6 to hoist the plate.

[0031] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
