Description

Technical Field

[0007]

[0001] The utility model belongs to the technical field of cargo hoisting, and specifically relates to an auxiliary device for cargo hoisting driven by a rope. Background Technique

[0002] In the modern cargo transportation and industrial production processes, the hoisting and transportation of goods is an extremely important link. In order to achieve efficient, safe and accurate cargo hoisting, various auxiliary devices have emerged. Among them, the auxiliary device for cargo hoisting and transportation driven by a rope is a key type of equipment. Such a device assists in the lifting, transportation and positioning of goods through the transmission of a rope, and is widely used in many industries such as construction, port logistics, manufacturing, etc.

[0003] In the existing auxiliary hoisting devices, as a common transmission component, the conveyor belt is very likely to loosen after long-term continuous use. The loosening of the conveyor belt not only affects the stability and accuracy of cargo hoisting, but may also cause safety hazards such as deviation and slipping of the cargo during transportation. Once such problems occur, it takes a lot of time and manpower to adjust, repair or even replace the conveyor belt, which undoubtedly increases the operating costs of enterprises and reduces production efficiency. At the same time, the loose conveyor belt may also cause equipment failures, further affecting the normal operation of the entire production process. Based on this drawback of the conveyor belt in the existing auxiliary hoisting devices, it is particularly urgent to develop an auxiliary device for cargo hoisting and transportation driven by a rope with better performance and stronger stability, which can effectively solve the problem of conveyor belt loosening, improve the safety and reliability of cargo hoisting and transportation, and provide strong support for the efficient development of related industries. Content of the Utility Model

[0004] In view of this, the utility model provides an auxiliary device for cargo hoisting driven by a rope, which can solve the problem that the conveyor belt will loosen after long-term use.

[0005] The utility model is realized as follows:

[0006] The utility model provides an auxiliary device for cargo hoisting driven by a rope, including a support frame, a rope transmission mechanism and a tension adjustment mechanism. The support frame is used to support the rope transmission mechanism and increase the height of the rope transmission mechanism. The tension adjustment mechanism is fixedly connected to the support frame. The rope transmission mechanism includes two transmission wheels and a conveyor belt. The two conveyor belts are respectively located at both ends of the support frame, and the two transmission wheels are respectively fixedly connected to the two tension adjustment mechanisms. The tension adjustment mechanism is used to adjust the height of the rope transmission mechanism and the tightness of the conveyor belt.

[0007] Based on the above technical solution, the following improvements can be made to an auxiliary device for cargo hoisting driven by a rope of the utility model:

[0008] The inner side of the conveyor belt is provided with a V-shaped groove, and correspondingly, the outer periphery of the drive wheel is provided with a corresponding V-shaped protrusion.

[0009] Furthermore, one side of the transmission wheel is rotatably connected to the tension adjustment mechanism via a motor.

[0010] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: By driving the transmission wheel with a motor, automated control of the transmission wheel can be achieved. This design allows the transmission wheel to automatically adjust its speed and direction as needed, thereby improving the convenience and efficiency of operation.

[0011] Furthermore, the transmission wheel is made of cast steel, and the V-shaped groove on the outer circumference of the transmission wheel has a depth of five percent of the wheel diameter, with a rounded corner radius of 2 mm at the bottom of the groove; the transmission wheel is rotatably connected to the tension adjustment mechanism via a self-aligning ball bearing.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: cast steel material has high strength and wear resistance, and can withstand large loads and long-term use. The V-groove design increases the contact area between the drive wheel and the conveyor belt, while the rounded corner design reduces stress concentration and extends the service life of the drive wheel.

[0013] Furthermore, the tension adjustment mechanism is an inverted L-shape, and its bottom is fixedly connected to the support frame via a telescopic mechanism.

[0014] The advantages of adopting the above-mentioned improved design are as follows: the inverted L-shaped structure allows the tension adjustment mechanism to flexibly adjust its height and position. This design not only improves the stability of the device but also facilitates installation and maintenance, while allowing for height adjustment according to actual needs.

[0015] Furthermore, the telescopic mechanism is a telescopic rod.

[0016] The beneficial effects of adopting the above-mentioned improved scheme are: the telescopic rod or lifting frame can achieve precise height adjustment. This allows the tension adjustment mechanism to quickly adjust the height as needed, thereby improving the flexibility and adaptability of the device.

[0017] Furthermore, the telescopic mechanism is a lifting frame.

[0018] Furthermore, the support frame includes a base frame and a hoisting bracket. The base frame is a rectangular plate located at the lowest point of the support frame. The hoisting bracket is an L-shaped support frame, with its horizontal portion fixedly connected to the base frame and its vertical portion used to support the tension adjustment mechanism. There are four hoisting brackets in a centrally symmetrical structure, with the two hoisting brackets at both ends fixedly connected to a tension adjustment mechanism.

[0019] The beneficial effects of adopting the above-mentioned improved scheme are as follows: this design makes the support frame more stable and able to withstand larger loads. The base frame is located at the lowest point, which can effectively distribute the weight, while the L-shaped hoisting bracket further enhances the rigidity and stability of the structure.

[0020] Furthermore, the vertical portion of the hoisting support is inclined toward the adjacent hoisting support.

[0021] The beneficial effects of adopting the above-mentioned improved scheme are as follows: the centrally symmetrical structural design ensures that the support frame is subjected to uniform stress, avoiding local stress concentration. This symmetry not only improves the overall strength of the device but also reduces deformation caused by asymmetrical stress.

[0022] Furthermore, the tilt angle of the hoisting support is 5 to 10°.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the inclined design of the hoisting support can optimize the force distribution, making the force more evenly transmitted to the support frame. This design not only improves the stability of the structure, but also reduces stress concentration caused by vertical force.

[0024] Compared with the prior art, the beneficial effects of the rope-driven cargo lifting auxiliary device provided by this utility model are:

[0025] The inner side of the conveyor belt has a V-shaped groove, and the outer side of the drive wheel has a corresponding V-shaped protrusion. This structure increases the friction and contact area between the conveyor belt and the drive wheel, effectively preventing the conveyor belt from loosening due to slippage or slippage during long-term operation;

[0026] By directly driving the transmission wheel with a motor, precise control over the wheel's speed and direction can be achieved. This design not only improves the stability of the conveyor belt operation but also facilitates timely adjustment of the conveyor belt tension, preventing the conveyor belt from loosening due to long-term use.

[0027] The drive wheel is made of high-strength cast steel, with a V-shaped groove on its outer circumference, the depth of which is 5% of the wheel diameter. This design increases the meshing strength between the drive wheel and the conveyor belt, while the rounded corners reduce stress concentration, extending the service life of the drive wheel and the conveyor belt, thereby reducing the problem of conveyor belt loosening caused by component wear.

[0028] The tension adjustment mechanism adopts an inverted L-shaped structure, with the bottom fixedly connected to the support frame via a telescopic mechanism. This design makes tension adjustment more flexible and precise, allowing for real-time adjustment of the conveyor belt tension as needed, preventing the conveyor belt from loosening due to long-term use.

[0029] The support frame includes a base frame and lifting brackets. The base frame is located at the lowest point, which can effectively distribute the weight, while the L-shaped lifting brackets enhance the rigidity and stability of the structure. The four centrally symmetrical lifting brackets distribute the force evenly, avoiding local stress concentration and further improving the overall strength of the device.

[0030] The vertical portion of the hoisting support is tilted 5–10° towards the adjacent support, optimizing the force distribution and allowing the force to be transmitted more evenly to the support frame. This design reduces stress concentration caused by vertical forces, further improving the stability of the structure.

[0031] Through the above improvements, the device effectively solves the problem of conveyor belts becoming loose after prolonged use, while also improving overall performance and adaptability. Attached Figure Description

[0056] The following is a specific application scenario of this utility model: This embodiment uses a cargo lifting auxiliary device for warehousing and logistics as an example for detailed description. The base frame is formed by bending 10 mm thick Q235 steel plate, with overall dimensions of 500 mm × 300 mm × 200 mm. A rectangular through hole with dimensions of 200 mm × 100 mm is opened in the center, and the rounded corner radius of the edges is 10 mm. Four 50 mm × 50 mm rubber shock-absorbing pads are welded to the bottom. The shock-absorbing pad material is nitrile rubber with a hardness of 60°. Two reinforcing ribs are symmetrically welded on the left and right sides. The thickness of the reinforcing ribs is 3 mm, and they are inclined at a 45-degree angle to the main body of the base frame.

[0057] The drive wheel is made of HT250 gray cast iron, with a diameter of 200 mm and a width of 50 mm. Six V-shaped grooves, each 10 mm deep, are evenly spaced on its outer circumference, with a 2 mm radius rounded corner at the bottom of each groove. The axle is 100 mm long and 25 mm in diameter at both ends, mounted on the base frame using self-aligning ball bearings (model 1205ETN9). The tension adjusting wheel, with a diameter of 160 mm, is parallel to the drive wheel and can be moved horizontally on the base frame using adjusting bolts. The lifting support is an L-shaped structure, formed from 50×50×5 angle steel, with a total height of 400 mm. It features a curved lifting ring at the top, with an inner diameter of 200 mm, an outer diameter of 220 mm, and a 5 mm outward-flaring edge at the end. The inner side has anti-slip textures. The safety locking mechanism's locking block is a 100 mm × 50 mm × 20 mm rectangular structure with a limiting groove on the side, connecting to the lifting support via a limiting pin. The entire device weighs approximately 45 kg and can carry a cargo weight of 500 kg, making it suitable for light to medium-sized warehousing and logistics operations.

[0058] The following is a detailed description of Example 2:

[0059] This embodiment uses a cargo lifting auxiliary device applied to engineering machinery hoisting operations as a specific example. The base frame is made of 12 mm thick Q345 high-strength steel plate, precisely formed by CNC bending equipment. The overall dimensions are 600 mm × 400 mm × 250 mm. A rectangular through hole with dimensions of 250 mm × 150 mm is opened at the geometric center, and the radius of the rounded corners is precisely controlled to 12 mm. Four 60 mm × 60 mm high-temperature resistant rubber shock-absorbing pads are strategically arranged at the bottom. The shock-absorbing pads are made of nitrile rubber composite material with a hardness of 70°, which can effectively absorb vibration and impact in ambient temperatures ranging from 60°C to -20°C. Two reinforcing ribs, 4 mm thick, are symmetrically welded on the left and right sides of the base frame. The reinforcing ribs are precisely inclined at a 45-degree angle to the main body of the base frame, and the structural integrity is ensured by high-strength welding process.

[0060] The drive wheel is made of high-strength gray cast iron HT300, with a diameter of 250 mm and a width of 60 mm. Eight trapezoidal V-shaped grooves, each 12 mm deep, are precision-machined on its outer circumference, with a 3 mm rounded corner radius at the bottom of each groove to ensure damage-free rope transmission. The axle is 120 mm long and 30 mm in diameter at both ends, precisely mounted using imported self-aligning ball bearings (model 2205ETN9). The bearing end seals are made of high-performance fluororubber, effectively preventing dust and moisture intrusion. The drive wheel surface undergoes plasma hard coating treatment, achieving a surface hardness of HRC58, significantly improving wear resistance.

[0061] The tension adjustment mechanism features a more precise design. The tension adjustment wheel has a diameter of 200 mm and is made of 42CrMo alloy steel with a carburized and quenched surface treatment, achieving a hardness of HRC45-50. The adjustment wheel is arranged parallel to the drive wheel, and a specially designed micro-adjustment bolt mechanism allows for precise horizontal displacement adjustment on the base frame, with an adjustment accuracy controllable within ±0.5 mm. Eight V-shaped grooves matching the drive wheel are formed on the outer circumference of the adjustment wheel. The groove depth and angle are consistent with the height of the drive wheel, ensuring ultimate stability of the rope transmission.

[0062] The hoisting support is made of 6061 high-strength aluminum alloy profile. The L-shaped structure is formed in one piece using a precision CNC machining center, with a total height of 500 mm and a crossarm length of 350 mm. The top features an innovative curved lifting ring with an inner diameter of 250 mm, an outer diameter of 280 mm, and a 6 mm outward flange at the end. The inner side uses an isostatic pressing process to create micron-level anti-slip textures. The lifting ring is 15 mm thick and undergoes a heat treatment strengthening process, achieving a tensile strength of up to 590 MPa, significantly improving hoisting safety.

[0063] The safety locking mechanism is more refined. The locking block is made of high-strength titanium alloy, measuring 120 mm × 60 mm × 25 mm, with precision-machined limit grooves on the side, the groove tolerance controlled within 0.01 mm. The limit pin is made of 316L stainless steel, with a polished surface, and the clearance between it and the limit groove is less than 0.02 mm, ensuring the absolute reliability of the locking mechanism. The locking block is connected to the hoisting bracket via miniature ball bearings, giving it a fine-tuning function and further improving safety.

[0064] The entire device weighs approximately 60 kg and can reliably support a load of 800 kg. It is suitable for lifting operations in harsh working environments such as medium-sized engineering machinery, metallurgy, and mining. The innovative design of the device significantly improves the stability, safety, and reliability of the cargo lifting process. Compared with traditional lifting auxiliary devices, it has significant improvements in key indicators such as vibration resistance, load-bearing capacity, and service life.

[0065] The specific method is as follows: First, install the device on the designated work platform, ensuring that the four rubber shock-absorbing pads at the bottom are in close contact with the ground. Check that the V-grooves of the drive wheel and tension adjusting wheel are clean, and ensure that the rope is correctly wound. Based on the weight and characteristics of the actual goods being lifted, precisely adjust the position of the tension adjusting wheel using the adjusting bolts to optimize the rope tension. Secure the goods to the lifting rings, ensuring the limit pins are in the safe locked position. Start the drive system and slowly pull the rope. During operation, closely observe the device's operating status and adjust the tension promptly to ensure the stability and safety of the lifting process.

[0066] Specifically, the principle of this utility model is as follows: the base frame is located at the lowest point, effectively distributing the weight. The L-shaped hoisting bracket enhances structural rigidity, and the four centrally symmetrical hoisting brackets ensure uniform force distribution; the motor drives the transmission wheel to rotate, driving the conveyor belt. The V-shaped groove and the protrusion on the transmission wheel increase friction, preventing the conveyor belt from slipping or loosening; the transmission wheel is made of high-strength cast steel, with a V-shaped groove design on its outer circumference, increasing the engagement strength with the conveyor belt, and reducing stress concentration through chamfering; the bottom of the inverted L-shaped tension adjustment mechanism is fixed to the support frame via a telescopic rod or lifting frame, adjusting the tension of the conveyor belt in real time to prevent slack.

[0067] Specifically, the operating steps of this device are as follows: Place the base frame in the designated position, ensuring its stability; install four L-shaped hoisting supports, with the horizontal parts fixedly connected to the base frame and the vertical parts used to support the tension adjustment mechanism; adjust the height and position of the inverted L-shaped tension adjustment mechanism using the telescopic rod or lifting frame, so that the two transmission gears are at different heights, and the conveyor belt is in an inclined setting; adjust the inclination angle of the conveyor belt to adjust its tension, ensuring that the conveyor belt is in an appropriate tension state; ensure that the goods are correctly fixed on the conveyor belt, start the motor, drive the transmission wheel to start rotating, and drive the conveyor belt to move, realizing the hoisting of the goods; during the hoisting process, closely observe the operating status of the device, check whether there is abnormal wear or loosening of the conveyor belt and transmission wheel, clean and lubricate the transmission components regularly, and ensure long-term stable operation of the equipment. If any problems are found, stop operation immediately and carry out maintenance.

[0068] Through the above steps, the device can efficiently and safely complete cargo lifting tasks, while effectively preventing the conveyor belt from loosening due to long-term use.
