Description

Technical Field

[0001] The present invention relates to the field of cable winding, and in particular to a cable winding device. Background Art

[0002] In the development of a multi-story parking garage, a carrier, the platform that provides a transfer platform for vehicles, requires mobility within a certain range. As the carrier moves, its power cables and control cables, which control its movement, also expand and contract. Therefore, cable reeling is crucial to ensure that the power and control cables remain connected to the carrier at all times and protect them from damage.

[0003] Currently, there are many cable winding devices, most of which are circular winding devices. Although this type of winding device can reel in the cable, it is unable to precisely control the length of the reeled cable. Moreover, as the circular reeling device is fully wound with cable, the diameter of the reel also changes, making it difficult to accurately control the release of the cable and calculate the length of the reeled cable.

[0004] At the same time, the diameter of the circular cable is constantly changing, and the force acting on the cable will also be constantly changing. Therefore, it is impossible to ensure that the force acting on the entire cable is consistent; after a long time, the life of the cable will be shortened.

[0005] The traditional cable winding method has a cylindrical structure. After the cable is wound, the winding position is actually random, which easily causes the cable to gather in a local position, which easily causes the cable to become "tangent" and thus reduces the cable life. Summary of the Invention

[0006] The present invention provides a cable winding device to solve the shortcomings of traditional cable winding devices, such as: 1. During the winding process of cables of different lengths, the cables are subjected to different forces; 2. Traditional cable winding cannot accurately control the winding length; 3. During the winding of traditional cables, the cables are easily gathered at a certain place to form an outline similar to a "peak" and a "valley". This winding easily causes the cables to slide from the "peak" to the "valley". After sliding, the cables with large diameters at the "peak" slide to the position with small diameters in the "valley", which causes the cables to be easily laminated by adjacent cables, and thus easily damage the cables; 4. After the traditional cable winding device is disconnected inside the cable, it directly affects the normal operation of the equipment. If redundant cables are added, the volume of the winding device will only become larger; 5. The traditional cable winding is a circular winding structure, and its overall volume is very large, and it cannot be made into a flat design. In order to solve the above problems, the present invention adopts the following technical solutions: A winding device includes a fixed seat, a guide rail being fixed to the fixed seat; a fixed shaft is provided on one side of the guide rail, and a fixed wheel group consisting of a plurality of independent pulleys is provided on the fixed shaft; a moving shaft is provided on the other side of the guide rail, which slides relative to the guide rail, and a plurality of moving wheel groups consisting of independent sliding wheels are provided on the moving shaft; The motion axis is fixedly connected via a connecting rod and the piston rod of the double-cylinder cylinder; A gas exchange port connected to the gas pipe is provided at the end of the cylinder in the direction of the moving wheel set. The gas exchange port is connected to the gas storage cylinder through the gas pipe in series with a proportional regulating valve. It also includes a cable, which is wound around the roller of the fixed wheel group and the roller of the moving wheel group, and the free end of the cable is connected to the carrier.

[0007] Furthermore, each pulley in the moving wheel set is connected to the moving shaft via an independent bearing; each pulley in the fixed wheel set is connected to the fixed shaft via an independent bearing.

[0008] Furthermore, the number of pulleys in the fixed wheel set and the movable wheel set are both even numbers.

[0009] Furthermore, there are two guide rails and they are arranged in parallel, and the ends of the two guide rails are respectively fixedly connected to the support plates to form a rectangular frame; the support plates are fixedly connected to the fixing seats. Furthermore, a wire-out guide wheel with a pulley structure is provided on the fixing seat; the free end of the cable passes through the pulley of the wire-out guide wheel.

[0010] Furthermore, the number of pulleys of the wire guide wheel is two.

[0011] Furthermore, an electronic pressure gauge is provided on the gas storage cylinder; a signal end of the electronic pressure gauge and a control end of the proportional regulating valve are electrically connected via a processor and a computer.

[0012] Furthermore, the end of the connecting rod is fixedly connected to the motion shaft in a "U"-shaped structure.

[0013] Furthermore, the number of the cables is two, and the two cables are wound around the fixed wheel set and the moving wheel set in a symmetrical manner.

[0014] Furthermore, the free ends of the two cables are led out from the central rollers of the fixed wheel group and the moving wheel group, and the free ends are connected to the carrier.

[0015] Compared with existing technologies, the present invention has the following advantages: It utilizes changes in air pressure to control cable reeling and the length and speed of cable recovery, enabling precise control. Furthermore, compared to purely mechanical reeling, the use of air pressure can resist instantaneous impacts on the cable, preventing internal cable breakage and damage. Furthermore, the present invention utilizes a sliding reel instead of a rolling reel, enabling a flatter design and preventing interlocking of cables. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but are not to be construed as limiting the present invention.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention discloses a winding wire device, which includes a fixed seat 10. The fixed seat 10 is a base for fixing, used for fixing the entire device, and the fixed seat 10 can also be fixedly connected to the three-dimensional parking garage. The guide rail 6 is fixedly installed on the fixed seat 10; specifically, the number of guide rails 6 is two and they are arranged in parallel, and the ends of the two guide rails are respectively fixedly connected to the support plate 4 to form a rectangular frame; the support plate 4 and the fixed seat 10 are fixedly connected. A fixed shaft 81 is provided on one side of the guide rail 6, and a fixed wheel group 8 composed of a plurality of independent pulleys is provided on the fixed shaft 81, such as Figure 1As shown, a fixed shaft 81 is fixed perpendicularly to the guide rail 6; on the other side of the guide rail 6 is a moving shaft 51 that slides relative to the guide rail 6. The moving shaft 51 is also perpendicular to the guide rail 6. A bearing is provided at the connection between the moving shaft 51 and the guide rail 6 to facilitate linear sliding of the moving shaft 51 on the guide rail 6. The moving shaft 51 is provided with a plurality of independently sliding moving wheel groups 5. Each pulley in the moving wheel group 5 is connected to the moving shaft 51 via an independent bearing; each pulley in the fixed wheel group 8 is connected to the fixed shaft 81 via an independent bearing. To ensure balanced forces between the fixed wheel group 8 and the moving wheel group 5, the number of pulleys in both the fixed wheel group 8 and the moving wheel group 5 is an even number.

[0020] like Figure 1 、 Figure 2 As shown, the motion shaft 51 is fixedly connected to the piston rod of the dual-cylinder cylinder 1 via a connecting rod 52. Specifically, the end of the connecting rod 52 is fixedly connected to the motion shaft 51 in a "U"-shaped structure. A gas exchange port connected to the air pipe is provided at the end of the cylinder 1 in the direction of the motion wheel group 5. The gas exchange port is connected to the air pipe in series with the proportional control valve 2 and then communicates with the air storage cylinder 3.

[0021] It also includes a cable 7, which is wound around the roller of the fixed wheel group 8 and the roller of the moving wheel group 5, and the free end of the cable is connected to the carrier. In order to facilitate the smooth connection of the cable 7 to the carrier, the fixed seat 10 is also provided with a pulley structure of the outlet guide wheel 9. The free end of the cable 7 passes through the pulley of the outlet guide wheel 9 and is connected to the carrier. The function of the outlet guide wheel 9 is to play a transition and connection role, so as to facilitate the smooth operation of the cable 7 and prevent it from being damaged by friction. Figure 2 and Figure 3 As shown, in the present invention, there are two outgoing wire guide wheels 9 and two cables 7, which are symmetrically wound around the fixed wheel group 8 and the moving wheel group 5. The free ends of the two cables 7 are both led out from the central rollers of the fixed wheel group 8 and the moving wheel group 5, and the free ends are connected to the carrier.

[0022] In the present invention, an electronic pressure gauge is provided on the gas storage cylinder 3; the signal terminal of the electronic pressure gauge and the control terminal of the proportional control valve are electrically connected via a processor and a computer. The signal of the electronic pressure gauge and the opening and control signal of the proportional control valve are connected via a communication protocol and computer software.

[0023] In order to solve the technical problems in the present invention, the technical principles of the main technical solutions are as follows: In the present invention, the moving shaft 51 slides linearly relative to the guide rail 6, while the fixed shaft 81 remains stationary relative to the guide rail. All pulleys on the moving shaft 51 and the fixed shaft 81 can rotate independently. When the transporter requires different cables 7 during movement, all pulleys are fully loaded with cables 7. The amount of cable 7 released depends on the distance between the moving shaft 51 and the fixed shaft 81, resulting in the same tension at every point on the cables 7.

[0024] When the carrier moves away from the fixed seat 10, the release length of the cable 7 is required to increase, the computer controls the proportional control valve 2 to open, and the carrier's own movement will drag the cable 7 to move the moving shaft 51 toward the fixed shaft 81. At this time, the piston will compress Figure 1 The compressed gas enters the air storage cylinder 3 in the space of the right cylinder 1. When the carrier approaches the fixed seat 10, the cable 7 will be full. The computer controls the opening of the proportional control valve 2 to replenish the high-pressure gas to the right cylinder 1, thereby moving the moving shaft 51 away from the fixed shaft 81, and finally completing the recovery of the cable 7. Before the device works, there will be a calibration step, which mainly includes: according to the different positions of the moving shaft 51 relative to the fixed shaft 81, the different positions of the piston in the cylinder 1 are corresponding, and then the different air pressure changes in the air storage cylinder 3 are simulated, and the air pressure change curve and the distance between the moving shaft 51 and the fixed shaft 81 are matched one by one. After the calibration is completed, precise control can be achieved by controlling the opening of the proportional control valve 2 by the computer to control the air pressure in the air storage cylinder 3. The cable length calculation, such as Figure 1 As shown, the distance between the moving axis 51 and the fixed axis 81 is L2, the stroke of the moving axis 51 is L1, and the moving range of the carrier is 2xNxL1.

[0025] It's important to emphasize that the instantaneous kinetic energy generated by the transporter's sudden movement is most likely to damage the metal core inside cable 7. Another benefit of using air pressure to control the length of cable 7 is that when the transporter's sudden and rapid movement creates a momentary impact on cable 7, air pressure control, due to its compressibility, provides significant elastic redundancy, enhancing the cable's ability to withstand the impact of that momentary tensile force.

[0026] The present invention uses the moving wheel group 5 and the fixed wheel group 8 to wind the cable 7. The cable 7 is always on the roller. Even when the cable 7 is recovered, only the distance between the moving axis 51 and the fixed axis 81 changes, thereby avoiding the phenomenon of the outgoing cable 7 gathering.

[0027] In order to ensure the tension balance of the cables 7, the present invention particularly sets the number of cables 7 to be two, and the arrangement of the two cables 7 is as follows: Figure 3 Arranging two cables 7 is not only for tension balance, but more importantly, it can ensure that the transporter will not stop working due to internal breakage of the cables 7.

[0028] The relative movement of the moving shaft 51 and the fixed shaft 81 completely changes the working principle of the traditional cable winding. The entire structure of the present invention can be made flat, which is very suitable for places with limited space such as multi-story parking garages.

[0029] The working steps of the present invention are as follows: According to the stroke range of the moving shaft 51, the change of the air pressure in the air storage cylinder 3 is recorded, and a corresponding diagram of the air pressure change curve and the stroke change is drawn.

[0030] When the carrier moves away from the mounting base 10, the computer opens proportional control valve 2. The carrier's own kinetic energy pulls on cable 7, forcing the gas in cylinder 1 on the right side of the piston into reservoir 3. When the carrier approaches the mounting base 10, the computer controls proportional control valve 2, adjusting the opening to control the speed and length of cable 7 retraction. Specifically, a smaller opening can be used for slower retraction, and the retraction cable 7 can be extended, allowing it to remain open for extended periods.

[0031] Through the above steps, the purpose of recycling the cables 7 in a limited space is achieved. The present invention is particularly suitable for cable recycling in a stereo garage.
