Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, specifically an adjustable steel truss floor deck hoisting tool. Background Technology

[0002] Steel truss floor deck hoisting tools are specialized equipment used for hoisting steel truss floor decks. Their core function is to safely and efficiently transport the floor decks to the designated location and ensure that the floor decks remain stable during the hoisting process, avoiding deformation or damage.

[0003] However, when existing steel truss floor deck hoisting tools are put into use, hook ropes are needed to hoist the floor deck. One end of the hook rope is fixed to the hoisting machinery, and the other end of the hook rope is hooked to the surface of the floor deck. When there is oil, rust or other impurities on the surface of the floor deck, the friction between the two is insufficient, which can cause the floor deck to tilt and detach in one place.

[0004] Meanwhile, during the hoisting of the floor decking using the hook rope, there will be a certain distance between the lower and upper ends of the hook rope. Due to the vibration of the hoisting machinery during use, the vibration effect is like ripples, starting from the source of the hoisting machinery and gradually transmitted from top to bottom along the hook rope. As the vibration energy is continuously transmitted and accumulated, the vibration amplitude at the lower end of the hook rope gradually increases. This large-amplitude vibration makes it difficult for the floor decking to remain stable during the hoisting process. Utility Model Content

[0021] 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.

[0022] Please see Figure 1-5As shown, an adjustable steel truss floor deck hoisting tool includes a fixed shell 1. Sliding shells 2 are slidably connected to the surfaces of both ends of the fixed shell 1. A stepper motor 3 is bolted to the front of the fixed shell 1. An adjustment mechanism 4 is provided inside the fixed shell 1. With the cooperation of the stepper motor 3 and the adjustment mechanism 4, the sliding shells 2 on both sides can move simultaneously in opposite directions on the surface of the fixed shell 1, enabling the tool to hoist floor decks of different sizes. A servo motor 5 is bolted to the top of the sliding shell 2. The output shaft of the servo motor 5 is driven to a winding roller 6. A hook rope 7 is movably connected to the surface of the winding roller 6. The number of servo motors 5, winding rollers 6, and hook ropes 7 are designed to correspond to each other. When the floor deck at the lower end of the hook rope 7 experiences uneven force, causing tilting, the hook rope 7 can be wound up with the cooperation of the servo motor 5 and the winding roller 6, thereby adjusting the balance of the floor deck. A rotating rod 8 is driven to the front of the winding roller 6. The front end of the rotating rod 8 is connected to two... A rotating shaft 9 is connected to a synchronous disc and a synchronous belt drive. With the cooperation of a servo motor 5 and a take-up roller 6, the rotating rod 8 and the rotating shaft 9 can rotate simultaneously. A moving mechanism 10 is set in front of the rotating shaft 9. A mounting shell 11 is bolted to the front side of the sliding shell 2. Under the action of the rotating shaft 9, the moving mechanism 10 can work on one side of the mounting shell 11. An auxiliary block 13 is installed below the mounting shell 11. The inner cavity on the right side of the auxiliary block 13 is slidably connected to the surface on the right side of the hook rope 7. Under the action of the moving mechanism 10, the auxiliary block 13 can descend with the hook rope 7, effectively reducing the large swing amplitude of the hook rope 7 during operation, thereby improving the stability of the tool for hoisting floor decking. A guide roller 14 is bolted to the surface on the right side of the sliding shell 2. The surface on the left side of another sliding shell 2 is bolted to the right side of another guide roller 14. Under the action of the guide roller 14, the descent direction of the hook rope 7 can be guided.

[0023] The adjustment mechanism 4 includes a bevel gear set 41. The front side of the bevel gear set 41 is fixedly connected to the output shaft of the stepper motor 3. The other side of the bevel gear set 41 is fixedly connected to a double-acting lead screw 42. Both ends of the double-acting lead screw 42 are threadedly connected to connecting sleeves 43. The top of the connecting sleeve 43 is fixedly connected to the top of the inner cavity of the sliding shell 2, and the bottom of the connecting sleeve 43 is slidably connected to the bottom of the inner cavity of the fixed shell 1. Under the action of the stepper motor 3, the bevel gear set 41 can drive the double-acting lead screw 42 to rotate in the inner cavity of the fixed shell 1. This allows the connecting sleeves 43 on both sides to drive the sliding shell 2 to move in opposite directions in the inner cavity of the fixed shell 1 at the same time. This allows the hook ropes 7 on both sides to adjust their positions according to the size of the floor deck, thereby improving the effectiveness of the tool.

[0024] The moving mechanism 10 includes a spur gear 101, the back of which is fixedly connected to the front of the rotating shaft 9. A gear rack 102 meshes with the right side of the spur gear 101, and a guide block 103 is bolted to the back of the gear rack 102. The surface of the guide block 103 is slidably connected to the inner cavity of the mounting shell 11. With the cooperation of the rotating rod 8 and the rotating shaft 9, the spur gear 101 can drive the gear rack 102 to move up and down, and the auxiliary block 13 can adjust its position by following the rise and fall of the hook rope 7. This effectively reduces the large swing amplitude of the hook rope 7 during operation and improves the stability of the tool for hoisting the floor deck. A guide groove 12 is provided on the front of the mounting shell 11. The inner cavity of the guide groove 12 is slidably connected to the surface of the guide block 103. The cross-sectional shape of the guide block 103 is T-shaped and corresponds to the shape of the guide groove 12. Under the action of the guide groove 12, the stability of the guide block 103 when moving in the inner cavity of the mounting shell 11 is improved.

[0025] Working principle: First, when the worker adjusts the position of the hook ropes 7 on both sides according to the size of the floor deck, the worker uses the stepper motor 3 to drive the bevel gear set 41 to rotate the double-acting screw 42. The double-acting screw 42, through the connecting sleeve 43, causes the sliding shells 2 on both sides to move in opposite directions on the surface of the fixed shell 1. The sliding shells 2 adjust the position of the hook ropes 7 on both sides through the winding roller 6. When the worker needs to hoist the floor deck, with the cooperation of the servo motor 5 and the winding roller 6, the hook ropes 7 can be moved downward through the guide roller 14, and the rotating rod 8 can be rotated. The rotating shaft 9 is rotated by two synchronous discs and a synchronous belt. The rotating shaft 9 drives the rack 102 to move the auxiliary block 13 downward through the spur gear 101. The rack 102 also drives the guide block 103 to move within the cavity of the mounting shell 11. Then, the workers hoist the floor deck through one end of the bottom of the hook ropes 7 on both sides. When the force is uneven when the tool hoists the floor deck, the hook rope 7 on one side can be moved upward with the cooperation of the servo motor 5 and the take-up roller 6, so that the hook rope 7 can drive the floor deck to adjust and balance. After the floor deck is hoisted, the workers can disassemble the floor deck.
