[0002] Tower crane is a common lifting equipment used on construction sites for transporting and lifting various construction materials and equipment. Tower crane consists of tower body, lifting arm, hanging basket mechanism and other components. It has the characteristics of large vertical height, small footprint and wide working range. The tower body of tower crane is generally made of steel structure and fixed to the ground by a special foundation to ensure its stability.

[0003] Tower cranes are usually used with hanging baskets to lift goods, but existing hanging baskets are usually fixed structures. When the length of the items to be lifted exceeds the length of the hanging basket, it is necessary to replace the hanging basket with another size. Replacing the hanging basket not only wastes time and reduces the lifting efficiency, but also increases the economic, storage and management costs. If the hanging basket is not replaced and the items exceed the outside of the hanging basket, it may cause the hanging basket to become unstable, tilt or fall, increasing the safety risk during the lifting process.

[0016] like Figures 1 to 4 As shown, a tower crane basket mechanism includes a base plate 1, an inner cavity 2, an extension plate 3, a first fence 4, a second fence 5, a slot 6, a plug rod 7, a support leg 8, a rubber pad 9, a drive mechanism 10, a tooth plate 11, a gear 12, a motor 13, a limit slide 14, a limit slider 15, a clearance groove 16, a fixing block 17, a screw 18, a universal wheel 19 and a lifting ring 20.

[0017] 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 of the embodiments.

In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] like Figures 1 to 4 As shown, an inner cavity 2 is opened inside the bottom plate 1, and two extension plates 3 are symmetrically arranged inside the inner cavity 2, and the ends of the two extension plates 3 extend to the outside of the inner cavity 2, first fences 4 are installed on both sides of the upper surface of the bottom plate 1, and second fences 5 are installed on the upper surfaces of the ends of the two extension plates 3. A plurality of slots 6 are opened inside the first fence 4, and two insertion rods 7 are symmetrically arranged inside the slots 6, and the opposite surfaces of the two insertion rods 7 are respectively connected to the opposite surfaces of the two second fences 5. Through the first fence 4, the second fence 5 and the insertion rods 7, the interior of the hanging basket can be an enclosed space, and when the extension plate 3 moves inside the inner cavity 2, the insertion rod 7 is retracted inside the slot 6, so that the interior of the hanging basket can be an enclosed space when it is adjusted to any size, thereby ensuring the safety of hoisting and preventing goods from falling.

[0021] A driving mechanism 10 is provided inside the inner cavity 2, and the driving mechanism 10 can drive the two extension plates 3 to move in opposite directions at the same time. By driving the two extension plates 3 to move in opposite directions at the same time by the driving mechanism 10, the purpose of adjusting the internal space of the hanging basket can be achieved.

[0022] Support legs 8 are installed at the four corners of the bottom of the bottom plate 1, and rubber pads 9 are arranged at the bottom of the support legs 8. The support legs 8 support the bottom of the bottom plate 1, which not only makes the hanging basket more stable when placed, but also provides installation space for the motor 13. When the tower crane places the hanging basket on the ground, the rubber pads 9 can play a buffering role, reduce the impact force generated, and increase the service life of the hanging basket. Both sides of the upper surface of the first fence 4 and the middle of the upper surface of the second fence 5 are installed with lifting rings 20. Through the setting of six lifting rings 20, the stability of the lifting can be guaranteed when the hanging basket is adjusted to any size.

[0023] The driving mechanism 10 includes two tooth plates 11 respectively installed on the opposite surfaces of the two extension plates 3, and the two tooth plates 11 are arranged parallel to each other. A gear 12 is rotatably installed inside the inner cavity 2, and the gear 12 is meshed and connected with the two tooth plates 11 at the same time. A motor 13 is installed at the bottom of the bottom plate 1, and the output shaft of the motor 13 is connected with the gear 12. When it is necessary to adjust the accommodating space of the hanging basket, the motor 13 can be started, and the output shaft of the motor 13 drives the gear 12 to rotate. Since the two tooth plates 11 are meshed with the gear 12, the two tooth plates 11 can be driven to move inward or outward at the same time, and the extension plate 3 can be driven to move, thereby achieving the purpose of adjusting the accommodating space. The operation is simple and the use is flexible.

[0024] Limiting grooves 14 are provided on both sides of the inner wall of the inner cavity 2, and limiting sliders 15 are installed on both sides of the extension plate 3. The limiting sliders 15 are arranged in the limiting grooves 14. By setting the limiting grooves 14 and the limiting sliders 15, the adjustment range of the extension plate 3 can be limited to prevent it from falling off from the inner cavity 2, so that the tooth plate 11 always keeps the meshing state with the gear 12. The two extension plates 3 are provided with clearance grooves 16 inside, and the two clearance grooves 16 correspond to the two tooth plates 11 respectively. When the two extension plates 3 are retracted into the inner cavity 2, the two tooth plates 11 are respectively inserted into the opposite clearance grooves 16, so that the two extension plates 3 will not be blocked by the tooth plates 11 and cannot approach, thereby expanding the adjustment range of the hanging basket.

[0025] Two fixing blocks 17 are installed on the outer surfaces of both sides of the base plate 1, and a screw rod 18 is vertically penetrated and threadedly connected inside the fixing block 17. A universal wheel 19 is installed at the bottom of the screw rod 18. When the hanging basket needs to be transferred, the screw rod 18 can be rotated to drive the universal wheel 19 to move downward and support the ground, so that the hanging basket can be easily pushed to move without manual handling, thereby improving the flexibility of use.

[0026] The working principle of the utility model is as follows: the straps are connected to the six lifting rings 20 for lifting. When it is necessary to lift longer objects, the motor 13 can be started to drive the gear 12 to rotate, and the gear 12 drives the two toothed plates 11 to move in the opposite direction, so that the two extension plates 3 are moved outward, and the distance between the two second fences 5 is expanded. Then the longer objects are placed in the hanging basket, and then the motor 13 is started again to drive the gear 12 to rotate in the opposite direction, so that the two second fences 5 are driven to approach each other and press against the two ends of the longer objects in the length direction, thereby clamping and fixing them to ensure stability during the lifting process. When it is necessary to transfer the hanging basket, the screw 18 can be rotated to drive the universal wheel 19 to move downward and support the ground, so that the hanging basket can be easily pushed to move without manual handling, thereby improving the flexibility of use.

[0027] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
