Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a building construction hoisting auxiliary tool. Background Technology

[0002] During construction, some buildings require spheres to meet design requirements. These spheres are typically positioned at considerable heights, necessitating lifting equipment to raise them to the required location. Currently, there are no dedicated lifting tools for spheres. The common practice is to wrap the sphere in a flexible bundle, secure it at the top with ropes, and then lift it using a crane at the rope connection. While this method provides some assistance, it has significant drawbacks: 1. The bundle is made of a soft material with limited strength, while the sphere is heavy, posing a safety hazard of the bundle tearing and the sphere slipping during lifting; 2. The rope securing method is time-consuming and labor-intensive, hindering work efficiency and operational standardization. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a construction hoisting auxiliary tool. This tool uses a rigid structure to temporarily store the sphere, and the sphere is easy to load and unload. It effectively solves the problems of tearing and causing the sphere to slip during bundle-assisted hoisting, and the resulting inefficiency and lack of standardized operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a construction hoisting auxiliary tool, comprising a cylindrical tube with a side opening, wherein lifting lugs are fixedly provided on the upper surface of the cylindrical tube at intervals on the left and right, and an inclined guide surface is provided at the lower edge of the right opening of the cylindrical tube, and an arc-shaped groove is embedded in the inner bottom surface of the cylindrical tube inside the guide surface.

[0005] The upper side plate at the right end of the cylindrical tube is provided with a limiting member extending from top to bottom.

[0006] As a preferred technical solution, the guide surface is an inclined surface with a thickness that gradually decreases from the inside to the outside, and the outer end is connected to the outer surface of the bottom of the cylindrical tube.

[0007] As a preferred technical solution, the arc-shaped groove is located at the center of the inner bottom surface of the cylindrical tube.

[0008] As a preferred technical solution, the limiting component includes a pin that slides through the upper side plate of the cylindrical tube, and a pull ring is fixedly provided on the top of the pin.

[0009] As a preferred technical solution, limiting blocks are fixed on both the front and rear sides of the center position of the bottom outer surface of the cylindrical tube. Each limiting block has a wedge-shaped structure, and the bottom surface of the two limiting blocks is at the same horizontal plane as the lowest position of the outer bottom surface of the cylindrical tube located between the two limiting blocks.

[0010] As a preferred technical solution, the inner surface of the cylindrical tube is provided with a rubber layer.

[0011] As a preferred technical solution, a pusher that can extend and retract inwards is provided at the center of the left end of the cylindrical tube.

[0012] As a preferred technical solution, the pusher includes a push rod that slides left and right through the left side plate of the cylindrical tube. A cylindrical handle is fixedly provided at the left end of the push rod. A spring is sleeved on the push rod to the right of the cylindrical handle. The left end of the spring is fixedly connected to the right side of the cylindrical handle, and the right end of the spring is fixedly connected to the outer surface of the left side of the cylinder.

[0013] Compared with the prior art, this utility model provides a construction hoisting auxiliary tool with the following advantages:

[0014] 1. This utility model features lifting lugs fixedly arranged on the upper surface of a cylindrical tube at intervals on the left and right. The lower edge of the right opening of the cylindrical tube has an inclined guide surface, and the inner bottom surface of the cylindrical tube inside the guide surface is embedded with an arc-shaped groove. In use, the cylindrical tube is initially placed on the ground, and the lifting lugs can be easily hooked and engaged with the hook of a crane. The ball can be rolled into the cylindrical tube from the right opening. The inclined guide surface facilitates the rolling in of the ball, and the arc-shaped groove limits the movement of the rolling ball. Compared with wrapping the ball in a bag, the cylindrical tube can effectively prevent the ball from slipping due to tearing.

[0015] 2. This utility model features a limiting component extending from top to bottom through the upper side plate of the right end of a cylindrical tube. The limiting component includes a pin that slides through the upper side plate of the cylindrical tube, with a pull ring fixed to the top of the pin. In use, after the ball rolls into the cylindrical tube, the pin is inserted into the cylindrical tube from the top, which can limit the ball at the right end and prevent the ball from slipping during lifting. After lifting to the high work platform, the pin can be pulled out first, and then the hook on the right side of the crane can be separated from the right lifting lug. The crane can only hook the left lifting lug and then pull upward, raising the left side of the cylindrical tube so that the ball can roll out of the right end of the cylindrical tube under the action of gravity. The overall operation is simple and standardized, which helps to improve work efficiency.

[0016] 3. This utility model has limiting blocks fixed on both the front and rear sides of the center position of the outer surface of the bottom of the cylindrical tube. Each limiting block has a wedge-shaped structure. The bottom surface of the two limiting blocks is at the same level as the lowest position of the outer bottom surface of the cylindrical tube located between the two limiting blocks. In use, the limiting blocks can limit the movement of the cylindrical tube on the front and rear sides of the ground at the beginning of the lifting and on the work platform at the end of the lifting, so as to prevent the cylindrical tube from rolling back and forth and improve the safety of operation.

[0017] 4. This utility model includes a push rod that slides left and right through the left side plate of the cylindrical tube. A cylindrical handle is fixedly provided at the left end of the push rod. A spring is sleeved on the push rod to the right of the cylindrical handle. The left end of the spring is fixedly connected to the right side of the cylindrical handle, and the right end of the spring is fixedly connected to the outer surface of the left side of the cylindrical tube. In use, after reaching the work platform at the lifting end point, the ball can be pushed to the right out of the cylindrical tube by pushing the push rod to the right on the left side of the cylindrical tube. This facilitates the ball's exit without the need for a lifting device to hook the left side lug to lift the left end of the cylindrical tube, thereby raising and tilting the left side of the cylindrical tube to exit the ball. The spring facilitates the return of the push rod to its original position. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0027] like Figures 1 to 4As shown, a construction hoisting auxiliary tool includes a cylindrical tube 1 with an opening on the right side. Lifting lugs 11 are fixedly provided at intervals on the upper surface of the cylindrical tube 1. An inclined guide surface 12 is provided along the lower edge of the right opening of the cylindrical tube 1. An arc-shaped groove 13 is embedded in the inner bottom surface of the cylindrical tube 1 inside the guide surface 12. A limiting member 3 is provided through the upper side plate at the right end of the cylindrical tube 1 from top to bottom.

[0028] The guide surface 12 is an inclined surface with a thickness that gradually decreases from the inside to the outside, and the outer end of the inclined surface is connected to the outer surface of the bottom of the cylindrical tube 1.

[0029] The arc-shaped groove 13 is located at the center of the inner bottom surface of the cylindrical tube 1.

[0030] The limiting component 3 includes a pin 31 that slides through the upper side plate of the cylindrical tube 1, and a pull ring 32 is fixedly provided on the top of the pin 31.

[0031] Limiting blocks 2 are fixed on the front and rear sides of the center position of the bottom outer surface of the cylindrical tube 1. Each limiting block 2 has a wedge-shaped structure. The bottom surface of the two limiting blocks 2 is at the same level as the lowest position of the outer bottom surface of the cylindrical tube 1 located between the two limiting blocks 2.

[0032] The inner surface of the cylindrical tube 1 is provided with a rubber layer (not shown). This layer serves to protect the sphere.

[0033] In use, the cylindrical tube 1 is initially placed on the ground. The two lifting lugs 11 facilitate engagement with the crane hooks (two in total). The ball 4 can roll into the cylindrical tube 1 from the right opening. The inclined guide surface 12 facilitates the rolling in of the ball 4, and the arc-shaped groove 13 limits the movement of the ball 4. Compared to wrapping the ball 4 in a bundle, the cylindrical tube 1 effectively prevents the ball 4 from slipping due to tearing. After the ball 4 rolls into the cylindrical tube 1, the pin 31 is inserted into the cylindrical tube 1 from the top. This limits the movement of the ball 4 at the right end, preventing it from slipping during lifting. After lifting to the high work platform, the pin 31 can be pulled out first. Then, the hook on the right side of the crane is separated from the right lifting lug 11, and the crane only hooks the left lifting lug 11. Then, it is pulled upwards, raising the left side of the cylindrical tube 1, allowing the ball 4 to roll out of the right end of the cylindrical tube 1 under gravity. The overall operation is simple and standardized, which helps to improve work efficiency. At the initial ground level and on the work platform at the end of the lifting operation, the limiting block 2 can limit the movement of the cylindrical tube 1 on both the front and rear sides, preventing the cylindrical tube 1 from rolling back and forth and improving operational safety. Example 2

[0034] like Figure 5 , Figure 6 As shown, a pusher 5 that can extend and retract inwards is provided at the center of the left end of the cylindrical tube 1.

[0035] The pusher 5 includes a push rod 51 that slides left and right through the left side plate of the cylindrical tube 1. A cylindrical handle 52 is fixedly provided at the left end of the push rod 51. A spring 53 is sleeved on the push rod 51 to the right of the cylindrical handle 52. The left end of the spring 53 is fixedly connected to the right side of the cylindrical handle 52, and the right end of the spring 53 is fixedly connected to the outer surface of the left side of the cylindrical tube 1. When the right end of the push rod 51 extends into the cylindrical tube 1 and the ball 4 is stationary in the arc-shaped groove 13, the left side surface of the ball 4 is in contact with the right end face of the push rod 51 (at this time, the push rod 51 exerts no pushing force on the ball 4).

[0036] When in use, after reaching the workbench at the lifting end point, the push rod 51 can be pushed to the right on the left side of the cylindrical tube 1. The push rod 51 can push the ball 4 out of the cylindrical tube 1 to the right, which facilitates the ball 4 to be discharged. There is no need for the lifting equipment to hook the left lifting lug 11 to lift the left end of the cylindrical tube 1, so that the left side of the cylindrical tube 1 is raised and tilted to discharge the ball 4. The spring 53 facilitates the reset of the push rod 51.
