Description

Technical Field

[0001] This invention relates to the field of vehicle transfer platform technology, specifically to a vehicle transfer platform cable-dragging device and a method for improving the efficiency of a coke-turning tank using the device. Background Technology

[0002] In the coking and coke-turning processes at coking plants, the transfer platform is a critical mobile device responsible for transporting coke cans between different workstations. To ensure the normal operation of the motors and control systems on the transfer platform, a continuous power supply connection is usually required between the fixed support and the moving transfer platform. Currently, cable-stayed power supply is widely used.

[0003] However, the existing cable-driven power supply mode for relocation platforms has revealed several technical shortcomings in actual high-frequency operations. When the relocation platform moves back and forth over long distances, the cable needs to be dragged along the ground or supports. Due to the lack of an effective rigid guide trajectory or constraint mechanism, the cable in its free state is prone to tangling and knotting due to the accumulation of its own torsional stress during repeated stretching and stacking. This disorderly tangling not only causes severe friction between the cable sheath and the ground, accelerating the aging and damage of the insulation layer, but in severe cases, it can even cause the internal core of the cable to break, forcing the entire coking system to stop for manual cable management or cable replacement, significantly reducing production efficiency.

[0004] Furthermore, to mitigate cable wear, some equipment has attempted to introduce steel cable sidings as suspension carriers. However, existing steel cable fixing structures often employ simple bolt-based rigid anchoring, failing to fully consider the physical properties of the metallic material. Metallic steel cables are sensitive to environmental temperature changes, exhibiting a significant thermal expansion and contraction effect. During periods of large seasonal temperature differences, steel cables sag considerably in summer due to thermal expansion, causing friction or jamming of the suspended cable upon contact with the ground; conversely, in winter, excessive tension stress arises from contraction due to cold, increasing the risk of cable breakage. Simultaneously, during long-term operation bearing the weight of the cable, steel cables undergo irreversible physical creep elongation. Existing static fixing methods cannot provide real-time dynamic compensation for tension fluctuations or length changes during operation, making it difficult to maintain a stable, linear guiding state.

[0005] Furthermore, as heavy equipment, the transfer platform operates under conditions involving frequent rapid starts, braking, and reversing. When the transfer platform suddenly stops at high speed, the cables following behind will continue to surge forward due to inertia, resulting in violent swaying and stacking. Existing transfer platform front-end structures typically lack dedicated protective facilities for flexible cables, and the stacked cables often directly and rigidly impact the front metal components of the transfer platform. This repeated rigid impact can easily cause damage to the cable insulation sheath from metal sharp edges, or lead to loosening and detachment of electrical connection terminals, thereby causing short-circuit power outages and affecting the continuity and safety of the coking operation. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a cable-dragging device for a transfer platform and a method for improving the efficiency of a coke-turning tank using the device, thus solving the problem of cables easily getting tangled and damaged during the movement of the transfer platform in existing technologies.

[0007] To achieve the above objectives, the present invention provides a cable-dragging device for a vehicle transfer platform. This device is used between the retaining wall and the vehicle transfer platform to solve the problems of cable tangling, delayed tension adjustment, and damage from inertial impacts in existing technologies. The device mainly includes steel pipes, steel cables, rope buckles, tensioning components, adjusting heads, and buffer protection components.

[0008] The steel pipe is a hollow tube structure, running through both ends of the transfer platform to provide a passage for the steel cable. The steel cable is inserted into the inner wall of the steel pipe, and its front and rear ends are anchored to the inner wall of the retaining pier through tensioning components. The steel cable, as the main mechanical load-bearing component, is suspended in mid-air. The mobile electrical box at the front of the transfer platform is connected to the switch box on the inner wall of the retaining pier via a cable. To constrain the cable's movement trajectory, the device employs multiple sets of figure-eight shaped rope loops. One end of each loop is looped around the outer wall of the steel cable, and the other end is looped around the outer wall of the cable. During the movement of the transfer platform, the steel cable restricts the radial freedom of the rope loops, forcing the cable to slide along a straight trajectory defined by the steel cable, thus physically isolating the cable from stress and transmission functions, preventing the cable from tangling during reciprocating motion.

[0009] For tension control of steel cables, this invention employs a mechanical structure that combines coarse and fine adjustment.

[0010] For coarse adjustment, an adjustment pan is installed on the fixed frame on the front surface of the transfer platform. The adjustment pan has multiple sets of adjustment holes in different positions. When the steel cable passes through different adjustment holes, the length or angle of its path changes, thereby mechanically limiting the initial tension of the steel cable and compensating for the macroscopic thermal expansion and contraction deformation of the metal material caused by seasonal temperature differences.

[0011] For fine-tuning, the tensioning assembly features an adaptive adjustment mechanism based on linkage. This assembly includes a fixed base, a sliding sleeve, a slider, a fixed sleeve, a threaded transmission pair, and an adjusting motor. The fixed base is installed on the inner wall of the retaining pier, and the sliding sleeve is hollow and houses the slider. The fixed sleeve passes through the end of the sliding sleeve and is fixed to the end of the steel cable. The adjusting motor drives the adjusting screw to rotate, causing the threaded block to move axially. The threaded block, through a hinged rod, forms a linkage structure with the slider and the fixed sleeve. When the threaded block moves, the angle change of the hinged rod drives the fixed sleeve to produce axial displacement relative to the sliding sleeve, thereby directly pulling or extending the steel cable, achieving slight tension compensation during operation and maintaining the straightness of the guide trajectory.

[0012] To protect cables from inertial impact, the front surface of the transfer platform is equipped with an air spring, a support plate, and an insulating protective plate. The support plate is installed at the output end of the air spring and perpendicular to the ground. The insulating protective plate, made of insulating neoprene rubber, is installed on the outside of the support plate and has a smooth surface. When the transfer platform stops suddenly, causing the cables to stack and sway, the smooth surface of the insulating protective plate first contacts the cables, providing low-friction sliding contact to protect the cable insulation layer. As the impact force increases, the support plate compresses the air spring, using pneumatic damping to dissipate the impact kinetic energy and prevent rigid impacts from damaging the equipment structure.

[0013] The second aspect of this invention provides a method for improving the efficiency of coke pan transfer on a vehicle transfer platform. This method utilizes the aforementioned cable-stayed transfer platform to improve the continuity and safety of coke pan handling operations by constructing a controlled transmission environment and dynamic adjustment mechanism. The method mainly includes the following implementation process: First, a flexible guided transmission channel is constructed. The steel cable is threaded through the steel pipe and adjusting head of the transfer platform, and both ends are anchored to the tensioning assembly. A figure-eight rope clamp is used to suspend the cable below. This step establishes and locks the cable's movement trajectory, eliminating the risk of knotting caused by free dragging.

[0014] Secondly, seasonal coarse adjustment of the base tension is performed. Based on the ambient temperature conditions, the adjustment holes at specific positions on the adjustment head are selected for the steel cable to pass through. By changing the geometric parameters of the steel cable's path, the length change of the steel cable caused by the ambient temperature difference is pre-absorbed or released, and the base tension range of the steel cable is set to prevent the steel cable from breaking due to being too loose to the ground or too tight.

[0015] Secondly, adaptive tension fine-tuning is implemented during operation. During the relocation of the cable at the coking platform, the tensioning assembly is activated to intervene in the cable tension in real time. By controlling the adjustment motor to drive the screw rotation, the axial displacement of the threaded block drives the linkage mechanism, converting and amplifying the driving force to cause the fixed sleeve to expand and contract axially. This process dynamically compensates for the creep or slight deformation of the cable under operating load, ensuring the stability of the cable protection system.

[0016] Finally, graded buffering and insulation protection are triggered. When cables stack due to inertia and impact the moving platform, the smooth surface of the insulation protection plate bears the relative sliding friction of the cables, preventing scratches; at the same time, the air spring's air chamber compression characteristics absorb and dissipate the impact kinetic energy. This step transforms rigid collisions into flexible contact, reducing the probability of cable joint loosening or breakage, and ensuring the long-term stable operation of the power supply system.

[0017] This invention provides a cable-dragging device for a vehicle transfer platform and a method for improving the efficiency of a coke-turning tank using this device. It has the following beneficial effects: 1. This invention constructs a flexible guiding and transmission channel for cables by setting up a steel pipe running through the transfer platform, a suspended steel cable, and figure-eight rope buckles. The figure-eight rope buckles are used to hang the cable below the steel cable, strictly limiting the cable's freedom of movement within the straight trajectory defined by the steel cable. This structure separates the cable's mechanical load-bearing function from its electrical transmission function, effectively avoiding the tangling and knotting phenomena caused by free stacking of cables in traditional towing methods, reducing the probability of unplanned downtime due to cable management, and ensuring the continuity of coking operations at the transfer platform.

[0018] 2. This invention employs a two-stage tension adjustment mechanism combining an adjusting disc head and a linkage-type tensioning assembly, solving the problem of cable tension instability caused by thermal expansion and contraction of metal materials and operational creep. The adjusting disc head coarsely compensates for significant deformation caused by seasonal temperature differences by changing the length or angle of the cable's path; the tensioning assembly uses a motor-driven screw and linkage slider mechanism to finely adjust for minor slack during operation. This design ensures that the cable maintains appropriate straightness under different ambient temperatures and long-term loads, preventing the cable from wearing down due to excessive looseness or breaking due to excessive tightness.

[0019] 3. This invention utilizes an insulating protective plate and an air spring to form a graded buffer protection system, enhancing the system's impact resistance. When the cable swings due to inertial movement during a sudden stop or reversal of the transfer platform, the smooth protective plate made of insulating neoprene rubber first bears the sliding friction of the cable, protecting the cable sheath from scratches; subsequently, the air spring absorbs the impact kinetic energy through the air chamber compression damping characteristics. This mechanism, which transforms rigid collisions into flexible contact, blocks the transmission of impact force to the cable joints and equipment structure, effectively preventing electrical faults caused by cable insulation damage or loose joints.

Detailed Implementation

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0023] Please see the appendix Figure 1 - Appendix Figure 5 This invention provides a vehicle relocation platform cable-dragging device, applied to a retaining pier 1 and a vehicle relocation platform 2, comprising: Steel pipe 8, a hollow pipe, runs through both ends of the transfer platform 2 and is added later by the operator. Steel cable 5 is inserted into the inner wall of steel pipe 8. Both ends of steel cable 5 are fixedly connected to the inner wall of the retaining block 1 via tensioning components 7. A fixing frame 9 is fixedly connected to the front surface of the transfer platform 2, and an adjusting head 10 is fixedly connected to the front surface of the fixing frame 9. The adjusting head 10 has multiple sets of adjusting holes for the steel cable 5 to pass through. By adjusting the steel cable 5 through different adjusting holes, the tension of the steel cable 5 can be adjusted to adapt to different seasons. A mobile electrical box 4 is installed at the front end of the transfer platform 2. A switch box 3 is installed on the inner wall of pier 1. The switch box 3 and the mobile switch box 4 are connected to each other by a cable 6. The outer wall of the steel cable 5 is fitted with multiple sets of rope buckles 14. The rope buckles 14 are set in a figure-eight shape, with one end looped around the outer wall of the steel cable 5 and the other end looped around the outer wall of the cable 6. When the moving platform 2 moves on the inner wall of pier 1, it will pull the cable 6 to move. The cable 6 will pull the rope buckles 14 to move on the outer wall of the steel cable 5. The steel cable 5 and the rope buckles 14 can provide guidance and support for the movement of the cable 6, thus preventing the cable 6 from getting tangled during the movement.

[0024] An air spring 11 is installed on the front surface of the transfer platform 2 near the bottom of the fixed frame 9. A support plate 12 is installed at the front end of the output shaft of the air spring 11. The support plate 12 is set perpendicular to the ground. An insulating protective plate 13 is installed on the side of the support plate 12 near the switch box 3. The side of the insulating protective plate 13 near the switch box 3 is set as a smooth surface. The insulating protective plate 13 is made of insulating neoprene rubber. When the transfer platform 2 moves back and forth, the insulating protective plate 13 can block the cable 6 and prevent the stacked cable 6 from directly colliding with the transfer platform 2, thus reducing the probability of damage to the cable 6.

[0025] Tensioning assembly 7 includes a fixed base 71, which is directly fixedly installed on the inner wall of the retaining block 1, providing support for the installation of the entire tensioning assembly 7. A sliding sleeve 72 is fixedly connected to the end of the fixed base 71 near the transfer platform 2. The sliding sleeve 72 is hollow and can accommodate other components. A fixed sleeve 74 is slidably connected through the end of the sliding sleeve 72 near the transfer platform 2. The end of the steel cable 5 is directly fixedly installed on the inner wall of the fixed sleeve 74. When the fixed sleeve 74 moves back and forth, it pulls the steel cable 5 to tension it. A slider 73 is slidably connected to the inner wall of the sliding sleeve 72. A threaded block 76 is hinged to the outer wall of the slider 73 via a hinge rod. Simultaneously, the threaded block 76 is hinged to the fixed sleeve 74 via the hinge rod. Thus, when the threaded block 76 moves closer to the sliding sleeve 72, the slider 73 and the fixed sleeve... 74 will move outward, at which point the steel cable 5 will be loosened. When the threaded block 76 moves away from the sliding sleeve 72, the slider 73 and the fixed sleeve 74 will move inward, at which point the steel cable 5 will be tightened. An adjusting motor 77 is fixedly installed on the outer wall of the sliding sleeve 72. The adjusting motor 77 is set perpendicular to the sliding sleeve 72. A threaded seat 75 is fixedly connected to the inner wall of the sliding sleeve 72. An adjusting screw 78 is rotatably connected through the inner wall of the threaded seat 75. The threaded block 76 is threadedly connected to the outer wall of the adjusting screw 78. The end of the adjusting screw 78 near the adjusting motor 77 is fixedly connected to the output shaft of the adjusting motor 77. With this configuration, the adjusting screw 78 can be rotated by adjusting the operation of the adjusting motor 77, which in turn drives the threaded block 76 to move, thereby achieving the effect of controlling the tension of the steel cable 5.

[0026] Reference Figure 6 The present invention also provides a method for improving the efficiency of coke tank transfer at a vehicle transfer platform, comprising the following steps: Step S1: Construct a flexible guided transmission channel The core of this step is to construct a physically isolated force-bearing system, thereby separating the mechanical load-bearing function of cable 6 from its electrical transmission function.

[0027] During the implementation process, the operator needs to weld or bolt the hollow metal structure steel pipe 8 to the internal structure of the transfer platform 2 along the horizontal axis. During installation, the centerline of the steel pipe 8 needs to be aligned to keep it parallel to the moving trajectory of the transfer platform 2. Then, the steel cable 5 is inserted into the internal channel of the steel pipe 8. The reserved length of the steel cable 5 should be greater than the sum of the total stroke of the transfer platform 2 and the distance between the stop 1.

[0028] After the steel cable 5 passes through the steel pipe 8, its two ends are respectively introduced into the tensioning components 7 located on the inner walls of both sides of the retaining pier 1, and fixed to the inner wall of the fixing sleeve 74 inside the component, so that the steel cable 5 is suspended in the air. In this structure, the steel cable 5 serves as the main mechanical load-bearing component to bear the tensile force.

[0029] After the foundation is erected, multiple sets of rope buckles 14 are installed. The upper annular hole of the rope buckle 14 is fitted onto the outer wall of the steel cable 5, ensuring that it can slide freely along the axial direction of the steel cable 5; at the same time, the lower annular hole of the rope buckle 14 is securely fitted onto the outer wall of the cable 6. Utilizing the unique figure-eight rigid structure of the rope buckle 14, the vertical distance between the cable 6 and the steel cable 5 is forcibly maintained at a constant value. When the transfer platform 2 moves and drives the mobile electrical box 4 to pull the cable 6, the cable 6 will undergo a driven displacement on the steel cable 5 through the rope buckles 14. Since the inner wall of the steel pipe 8 only contacts the steel cable 5 and the rope buckles 14, the cable 6 is physically constrained within a predetermined trajectory below the steel cable 5. This constraint mechanism effectively avoids tangling or knotting caused by free stacking of the cable.

[0030] Step S2: Perform seasonal basic tension coarse adjustment This step utilizes the difference in geometric position on the adjusting pan head 10 to compensate for the macroscopic thermal expansion and contraction deformation of the metal material caused by seasonal temperature differences.

[0031] The implementation should be based on the ambient temperature and season. When the ambient temperature is high, such as in summer, the steel cable 5 will physically elongate due to heat. In this case, the operator needs to pass the steel cable 5 through the adjustment hole on the adjustment head 10 that is far from the fixed point or has a more tortuous path. This threading path forces the steel cable 5 to have a larger deflection angle or displacement when passing through the adjustment head 10, thereby effectively absorbing the excess length of the steel cable 5 caused by thermal expansion and preventing the steel cable 5 from drooping and touching the ground due to excessive slack.

[0032] Conversely, when the ambient temperature is low, such as in winter, the steel cable 5 will physically shrink due to the cold. In this case, the operator should switch the steel cable 5 to the adjustment hole on the adjustment head 10 that is closer to the fixed point or has a straighter path. This path can reduce the constraint distance of the steel cable 5, thereby releasing part of the cable length and preventing the steel cable 5 from generating tensile stress exceeding its yield strength due to excessive shrinkage at low temperatures, thus eliminating the risk of breakage.

[0033] Step S3: Implement adaptive tension fine-tuning during operation. This step uses the linkage transmission mechanism inside the tensioning assembly 7 to provide real-time dynamic compensation for tension fluctuations that occur during operation.

[0034] The specific operation process is as follows: When the system needs to increase the tension of the steel cable 5, the control adjustment motor 77 is started. The output shaft of the adjustment motor 77 rotates and drives the adjustment screw 78, which is rigidly connected to it, to rotate within the threaded seat 75. The threaded block 76 is driven by the thread of the adjustment screw 78 and moves linearly outward in a direction away from the sliding sleeve 72.

[0035] As the threaded block 76 moves outward, the angle of the hinge rod connecting the threaded block 76 and the fixed sleeve 74 changes. This mechanical linkage forces the slider 73 and the fixed sleeve 74 to contract inward, causing the fixed sleeve 74 to displace away from the transfer platform 2. This displacement of the fixed sleeve 74 directly pulls the end of the steel cable 5 fixed to its inner wall, thereby increasing the axial tension of the steel cable 5 to eliminate slack.

[0036] When it is necessary to reduce the tension of the steel cable 5 to prevent overload, the control adjusting motor 77 rotates in the reverse direction. The threaded block 76 then moves closer to the sliding sleeve 72. The hinge rod pushes the slider 73 and the fixed sleeve 74 to extend outward from the sliding sleeve, causing the fixed sleeve 74 to move closer to the transfer platform 2. The steel cable 5 is then delivered, and its axial tension is reduced. This process can be performed continuously or intermittently during the transfer platform movement operation to ensure that the steel cable 5 is always maintained within the set straightness range, thereby reducing the frictional resistance when the rope buckle 14 slides.

[0037] Step S4: Trigger graded buffering and insulation protection This step utilizes material properties and aerodynamic principles to solve the problem of inertial impact generated by the transfer platform 2 in a non-uniform motion state.

[0038] When the transfer platform 2 performs an emergency stop or rapid reversal operation at high speed, the trailing cable 6 will continue to move forward due to inertia and will stack and swing. At this time, the outer sheath of the cable 6 will first come into contact with the insulating protective plate 13. Since the insulating protective plate 13 is made of insulating neoprene rubber and has a smooth surface, the cable 6 will slide relative to each other on the contact surface. This design avoids the cutting or wear of the cable insulation layer by the rough metal surface.

[0039] If the inertial force is large, cable 6 will continue to compress the insulating protective plate 13. This pressure will be transmitted to the air spring 11 through the support plate 12. The air chamber inside the air spring 11 deforms under pressure, the gas is compressed and generates a reverse damping force. This process converts the kinetic energy of cable 6 into the internal energy of the gas and the potential energy of the spring, thereby flexibly absorbing the impact energy. After the inertial force disappears, the air spring 11 rebounds to its original position. This graded buffering mechanism blocks the transmission path of rigid impact to the cable joint and the front structure of the transfer platform, achieving effective protection for the equipment.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
