Description

Technical Field

[0001] This utility model relates to the field of wind farm equipment transportation technology, and in particular to an auxiliary uphill device suitable for a wind farm equipment transportation vehicle in mountainous areas. Background Technology

[0002] In the construction of mountain wind farms, the transportation of large wind power equipment (such as wind turbine blades, hubs, and nacelles) is one of the key aspects. Due to the complex mountainous terrain, the transportation roads often have continuous curves and steep slopes, posing a great challenge to heavy-duty transport vehicles (usually semi-trailer models) during the journey.

[0003] In existing technologies, traditional solutions to the problem of heavy-duty transport vehicles struggling to climb hills often involve enhancing the power of the tractor unit or adding an extra towing vehicle. However, these methods have significant drawbacks: traditional traction methods only act on the tractor unit, and the traction force must be transferred to the trailer through the connection structure between the tractor unit and the trailer. During this transfer process, a significant amount of tensile force is lost due to mechanical wear and deformation of the connection structure, resulting in a substantial reduction in the effective traction force actually acting on the heavy-duty trailer.

[0004] Therefore, there is an urgent need for an auxiliary device that can directly act on heavy-duty trailers to solve the problem of large traction loss in existing technologies. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] The following is combined Figures 1-6 The present invention describes an auxiliary uphill device for a mountain wind farm equipment transport vehicle, comprising a fixed support column 1, a lifting device 2, a movable pulley 3, and a steel wire rope 4.

[0028] Fixed support pillars 1 are installed in pairs, serving as core support components, and are symmetrically distributed on both sides of the transport channel, forming a double-sided traction support system. Fixed support pillars 1 provide the installation foundation for the lifting equipment 2, ensuring vertical support stability. The lifting equipment 2 is installed in a one-to-one correspondence with the fixed support pillars 1, and is used to provide traction power. Movable pulleys 3 are detachably installed on the rear half of the semi-trailer 101 of the transport vehicle 100 (usually the front half of the semi-trailer is connected to the cab). Movable pulleys 3 are located on the side of the transport vehicle 100 facing away from the semi-trailer 101, and are positioned in the middle of the transport channel along its width to prevent interference between the wire rope and the cab. Of the two wire ropes 4, one end of the first wire rope 4 is connected to the lifting equipment 2 on the first side, and the other end is connected to one side of the movable pulley 3; one end of the second wire rope 4 is connected to the lifting equipment 2 on the second side, and the other end is connected to the other side of the movable pulley 3.

[0029] The embodiment provided by this utility model can directly apply traction force to the rear half of the semi-trailer 101, avoiding the loss of traction force transmitted to the trailer through the tractor in the traditional traction method, greatly improving the effective traction force applied to the semi-trailer, and solving the problem of insufficient power for heavy-duty transport vehicles going uphill. Moreover, the two steel wire ropes 4 and the movable pulley 3 form a double-sided traction, breaking through the traditional power source design, providing a basis for adjusting the direction of traction force, and avoiding directional deviation caused by unilateral traction.

[0030] In some feasible embodiments of this utility model, a guide structure is also included for providing guidance for the wire rope 4.

[0031] In some feasible embodiments of this utility model, the guide structure includes a sleeve 5 and a fixed pulley 6. The sleeve 5 is coaxially rotatably sleeved on the outside of the fixed support 1, with a small gap between them and a wear-resistant coating, allowing the sleeve 5 to rotate flexibly in the horizontal plane around the axis of the fixed support 1. A lifting device 2 is provided on the sleeve 5. The fixed pulley 6 is provided on the sleeve 5, and the fixed pulley 6 is for the wire rope 4 to pass over. That is, after one end of the first wire rope 4 is connected to the lifting device 2, it passes over the corresponding fixed pulley 6 and is connected to one side of the movable pulley 3. After one end of the other wire rope 4 is connected to the corresponding lifting device 2, it passes over the corresponding fixed pulley 6 and is connected to one side of the movable pulley 3, forming an angle adjustment mechanism for the fixed support 1, sleeve 5, and fixed pulley 6, ensuring that the fixed pulley 6 can adaptively adjust its orientation according to the change in the tension direction of the wire rope 4.

[0032] Among them, sleeve 5 is made of 20# seamless steel pipe with an inner diameter of 305mm and a length of 350mm, and the inner wall is coated with a 0.5mm thick polytetrafluoroethylene wear-resistant coating. The fixed pulley 6 is made of cast steel with a diameter of 300mm, and the bearing seat adopts a deep groove ball bearing to ensure that the fixed pulley 6 rotates flexibly.

[0033] In some feasible embodiments of this utility model, the lifting device 2 includes a motor 21 and a drum 22. The motor 21 is mounted on the fixed support 1; the drum 22 is mounted at the output end of the motor 21, and one end of the wire rope 4 is wound around the drum 22.

[0034] In other words, two electric motors 21 are installed on fixed pillars 1 on both sides of the road, and the output drum 22 winds the steel wire rope 4. The steel wire rope 4 passes around the fixed pulley 6 and is connected to both ends of the movable pulley 2 to form a double-sided traction transmission chain.

[0035] In addition, all motors 21 are variable frequency speed control motors with the same rated power. Each motor is equipped with an independent overload protection device, which includes a tension sensor and a thermal overload relay. The tension sensor is installed on the corresponding side of the wire rope 4 to detect the tension of the wire rope 4 in real time. When the tension of any wire rope 4 exceeds the set threshold, the controller 4 triggers the motor 21 to stop, and the motors 21 on both sides stop synchronously.

[0036] The drum 22 is a cast steel part with a diameter of 500mm and a length of 800mm, and its surface is provided with a spiral anti-slip rope groove. The steel wire ropes 4 are all high-strength galvanized steel wire ropes with a diameter of 20mm to ensure sufficient breaking tensile strength. Their lengths are determined according to the spacing of the fixed support columns 1, and they are wound around the drum 22 on both sides respectively.

[0037] In some feasible embodiments of this utility model, an angle detector 7 and a controller are also included. The angle detector 7 is mounted on the semi-trailer and is used to detect the angle signal of the semi-trailer 101's forward direction. The angle signal includes the slope angle and the lateral deflection angle. The controller is communicatively connected to the angle detector 7 and the lifting device 2; the controller is used to receive the angle signal and control the output power of the lifting device 2 so that the resultant force of the two steel wire ropes 4 is aligned with the forward direction of the semi-trailer.

[0038] The angle detector uses a high-precision dual-axis tilt sensor.

[0039] More specifically, the controller has a built-in power distribution and angle adjustment linkage algorithm. When the lateral deflection angle changes, the controller first adjusts the output power of the motors 21 on both sides, and then drives the sleeve 5 to rotate around the fixed support 4 through the tension of the wire rope 4, so that the fixed pulley 6 always matches the direction of the tension of the wire rope 4.

[0040] In the above embodiments, the controller determines the total traction force requirement based on the slope angle, and outputs the power of the lifting devices 2 on both sides according to the lateral deflection angle. At the same time, it adjusts the orientation of the fixed pulley 6 by rotating the cylindrical sleeve 5 horizontally, so that the fixed pulley is adjusted synchronously with the tension direction of the wire rope 4. Finally, the tension of the wire ropes on both sides forms a resultant force along the forward direction of the semi-trailer, and the direction of the resultant force is always consistent with the forward direction of the semi-trailer 101, so as to avoid the semi-trailer 101 from deviating and solve the problem of low directional control accuracy under curve conditions.

[0041] When the semi-trailer veers laterally, the controller first adjusts the power of the motors on both sides, changing the tension difference of the wire rope 4. Then, this tension difference drives the cylindrical sleeve 5 to rotate, aligning the fixed pulley 6 with the tension direction of the wire rope 4, thus preventing additional frictional losses between the fixed pulley 6 and the wire rope 4. In other words, the cooperation between the angle detector 7 and the variable frequency motor 21 allows for real-time adjustment of the traction force according to changes in slope, while also adapting to curves, preventing trailer deviance, and improving transportation safety.

[0042] More specifically, the two motors 21 are variable frequency speed control motors of the same specifications, which can achieve precise power adjustment. Each motor 21 is equipped with an overload protection device, which will stop synchronously when the tension of the wire rope 4 exceeds the standard, to prevent the semi-trailer 101 from becoming unbalanced due to a single-sided shutdown, and at the same time protect the motor 21 and the wire rope 4 from damage.

[0043] In some feasible embodiments of this utility model, a fixed base plate 8 and a counterweight device 9 are also included. The fixed base plate 8 is a prefabricated design, with the fixed base plate 8 positioned at the bottom of the fixed support column 1. The fixed support column 1 is made of high-strength solid round steel, and is combined with the circular fixed base plate 8 and reinforcing ribs to enhance vertical load-bearing capacity and bending resistance. The counterweight device 9 is detachably connected to the fixed base plate 8. The fixed support column 1 is securely mounted on the counterweight device 9 via the fixed base plate 8, ensuring the structural stability of the fixed support column 1, preventing misalignment during traction, and ensuring that the fixed support column 1 does not tilt under heavy load.

[0044] Specifically, the fixed support column 1 is made of solid round steel, specifically 45# solid round steel with a diameter of 300mm and a length of 2.8m. The fixed base plate is a Q235 round steel plate with a thickness of 25mm and a diameter of 450mm. The bottom of the fixed support column 1 is welded to the center of the fixed base plate 4, and four reinforcing ribs with a specification of 100mm×80mm×10mm are evenly distributed at the weld. The ribs are welded and fixed to both the fixed support column 1 and the fixed base plate 8. The fixed base plate 8 is a round steel plate with a thickness of 20-30cm and a diameter of 400-500mm. The bottom of the fixed support column 4 is rigidly connected to the center of the fixed base plate 8 by welding, and reinforcing ribs are provided at the weld.

[0045] More specifically, the counterweight device 9 includes a counterweight base and pre-embedded bolts. The counterweight base may have a pre-drilled hole 91 in the middle, and the pre-embedded bolts are installed in the pre-drilled hole 91. The counterweight base provides stability to the fixed support column 1 through its own weight. The pre-embedded bolts are detachably connected to the fixed base plate 8.

[0046] The counterweight base is made of cast iron or concrete counterweight blocks, weighing 500-800 kg, and is cylindrical or cubic in shape. The diameter of the pre-made hole 91 is 5-10 mm larger than the diameter of the fixed support 1 to ensure that the fixed support 1 can pass through smoothly. After the fixed support 1 passes through the pre-made hole 91, the bottom of the counterweight base is in contact with the upper surface of the fixed base plate 8. The counterweight base presses the fixed base plate 8 with its own weight, further enhancing the anti-tipping ability of the fixed support 1 and preventing the fixed support 1 from shifting during the traction process.

[0047] The counterweight foundations and fixed support columns 1 on both sides of the road are symmetrically distributed, and the fixed pulleys 6 are at the same height to ensure that the wire ropes on both sides are subjected to balanced force in the initial state, reduce the amount of debugging work after the device is assembled, and improve traction stability.

[0048] In some feasible embodiments of this utility model, a tripod 10 is also included. The inner diameter of the sleeve 5 is 2-5mm larger than the outer diameter of the fixed support 1. The inner wall of the sleeve 5 is provided with a wear-resistant coating made of polyvinyl fluoride, which reduces friction with the fixed support 1 and ensures rotational flexibility. The outer wall of the sleeve 5 is connected to the first end of the tripod 10, and the other end of the tripod 10 is connected to the fixed pulley 6 through a bearing seat, which ensures the installation stability of the fixed pulley without affecting its rotational function. The rod of the tripod 10 is made of seamless steel pipe with a diameter of 50-60mm. The tripod 10 adopts a triangular stability structure. Preferably, the rod of the tripod is a seamless steel pipe with a diameter of 55mm, arranged in an equilateral triangle. One end is welded to the outer wall of the cylindrical sleeve 5, and the other end is welded to a mounting plate with specifications of 150mm×100mm×15mm. The mounting plate is connected to the bearing seat of the fixed pulley 6 by bolts.

[0049] The cylindrical sleeve 5 has an inner wall with a diameter of 305mm and a length of 350mm, coated with a 0.5mm thick polytetrafluoroethylene (PTFE) wear-resistant coating. The tripod's pole is a seamless steel pipe with a diameter of 55mm, arranged in an equilateral triangle. One end is welded to the outer wall of the sleeve 5, and the other end is welded to a mounting plate with dimensions of 150mm×100mm×15mm. The mounting plate is connected to the bearing seat of the fixed pulley 6 by bolts. The fixed pulley 6 is made of cast steel with a diameter of 300mm, and the bearing seat uses a deep groove ball bearing to ensure the flexible rotation of the fixed pulley 6.

[0050] In some feasible embodiments of this utility model, the axle of the movable pulley 3 is provided with connecting lugs at both ends, and the ends of the two steel wire ropes 4 are detachably connected to the connecting lugs, which facilitates later maintenance and replacement while ensuring connection strength. A connecting hook 11 is also provided in the middle of the axle of the movable pulley 3, and a fixing ring 12 is welded onto the semi-trailer 101. The connecting hook 11 and the fixing ring 12 are detachably connected. More specifically, an elastic locking piece is provided at the opening of the connecting hook 11 to prevent it from falling off during transportation.

[0051] In some feasible embodiments of this utility model, the breaking tensile strength of the wire rope 4 is greater than or equal to 1.5 times the maximum load capacity of the transport vehicle 100. More specifically, the two wire ropes 4 are of the same specification, both using high-strength galvanized steel wire rope. The diameter of the wire rope 4 is determined according to the maximum load capacity of the transport vehicle, and the breaking tensile strength of the wire rope 4 is not less than 1.5 times the maximum load capacity of the transport vehicle, so as to ensure that the wire rope 4 has sufficient rigidity and strength.

[0052] The auxiliary uphill device for transporting equipment in mountain wind farms provided in this embodiment of the utility model involves pre-embedding pre-assembled counterweight devices on both sides of the gentle slope, steep slope, and sharp bend sections of the transport road in the mountain wind farm before transportation. The fixed support column 1 is fixed with the pre-embedded bolts, and the fixed pulley 1 and motor 21 are installed. The movable pulley 3 is connected to the fixing ring 12 of the semi-trailer 101, and then the two steel wire ropes 4 are respectively connected to the drums 22 on both sides, the fixed pulley 6 and the movable pulley 3 to complete the assembly.

[0053] Operating on a gentle slope: Start the transport vehicle and the auxiliary uphill device. The angle detector 7 detects the slope angle and lateral deflection angle and transmits the data to the controller. The controller calculates the total traction force requirement. Since the lateral deflection angle is 0°, the output power of the motors 21 on both sides is the same. The drum 22 synchronously winds up the wire rope 4. The resultant force direction is consistent with the forward direction of the semi-trailer 101, and the auxiliary transport vehicle 100 smoothly goes uphill.

[0054] Operating on sharp bends: When the transport vehicle 100 travels to a sharp bend, the angle detector 7 detects the lateral deflection angle and transmits the data to the controller; the controller adjusts the power distribution according to the algorithm, the output power of the motor 21 closer to the inside of the bend is reduced, and the output power of the motor 21 on the outside is increased, so that the resultant force of the pulling force on both sides is consistent with the forward direction of the semi-trailer, thus preventing the trailer from deviating to the inside.

[0055] The fixed support 1 is designed differently according to different working conditions such as gentle slope, steep slope, and sharp bend, which not only ensures the continuous action of traction force under various working conditions, but also avoids the cost waste caused by excessive density of the fixed support 1, thus improving the practicality of the device.

[0056] Overload protection: If the tension of the steel wire rope 4 increases to the set threshold due to road surface protrusion during transportation, the tension sensor will transmit the signal to the controller, and the controller will immediately trigger the overload protection device of the motor 21, and the motors 21 on both sides will stop synchronously; after the driver troubleshoots the fault, the auxiliary hill-climbing device will be restarted by resetting through the controller.
