Description

Technical Field

[0001] The invention relates to the field of subway vehicle electrical technology, and in particular to a large-line cable inching winding device. Background Art

[0002] The electrical system of subway vehicles contains various types of cables, and various types of cables need to be prepared for offline according to offline technical documents. Large-line cables are commonly used in subways with cable diameters of 16 square meters or more, and the maximum diameter is 150 square meters. The offline preparation process of large-line cables first cuts different types of cables according to the required offline length according to the offline technical documents, and then coils the cut cables into a circle. The coiled cables are prepared for the wiring of the next process of subway vehicles.

[0003] The existing solutions for winding cables before going offline are divided into manual winding and winding cables with winding devices. The manual winding cable solution is flexible to operate, but the efficiency is difficult to guarantee. Patent CN 220811393 U manually operates the rotating rod, which is linked to the turntable. During the rotation of the turntable, the cable is coiled into a circle to achieve cable winding. However, the efficiency of winding cables by manually operating the rotating rod is low. For example, when winding cables with large diameters and long distances, the weight of the cable needs to be overcome when manually operating the rotating rod, and the cable winding speed is difficult to guarantee. The weight of the large-line cable affects the force on the winding mechanism of the horizontal structure. The weight of the cable is proportional to the diameter of the cable. After the large-line cable is coiled into a circle, the weight of the cable exerts a downward force on the winding mechanism, which easily causes the winding mechanism to be tilted. After the cable is coiled, the cable needs to be manually removed from the winding mechanism. The operation is inconvenient and consumes a lot of manpower, which affects the efficiency of offline preparation.

[0004] The cable winding scheme of the winding device is to coil the cable through a mechanical device, and the winding speed is fast. Patent No. CN117342358A drives the winding mechanism to rotate through a motor, and the cable is coiled when the winding mechanism rotates. Before coiling the cable, the winding mechanism is manually operated to expand. After coiling the cable, the winding mechanism is manually operated to shrink. After the winding mechanism shrinks, the wound cable is manually lifted from the winding mechanism to complete the cable winding. However, before and after the cable is coiled, the handle in the winding mechanism needs to be operated to be linked with the screw structure. The screw structure drives the connecting rod to expand and shrink. This screw structure requires manual rotation of the handle multiple times before the connecting rod can be expanded and retracted. Manual forward and reverse rotation of the handle controls the expansion and contraction of the connecting rod 14, which is inconvenient to operate and affects efficiency. The connecting rod structure in the winding mechanism has a shape similar to a "W". The cable fixing mold in the winding mechanism is installed on the connecting rod and tilted outward. When the cable is coiled, the cable is located between the cantilever structure and the fixed cable mold in the winding mechanism. The connecting rod structure tilted outwards makes it difficult to lift the cable upward from the winding mechanism after the cable is coiled. After the large cable is coiled, it needs to be manually lifted upward from the winding mechanism. The cable lifting process consumes a lot of manpower, affecting the efficiency of offline preparation. Summary of the invention

[0005] According to the above technical problem that the existing cable winding device needs to manually lift the cable after winding, a large-line cable inching winding device is provided. The present invention mainly controls the cable to be lifted upward by a cylinder during the process of lifting the cable from the winding mechanism. The problem of manually lifting the cable upward is solved, the workload is reduced, and the efficiency of offline preparation is improved.

[0008] Furthermore, the winding mechanism includes a connecting disk, the lower part of the connecting disk is connected to the reducer, a center column is fixed at the center of the upper surface of the connecting disk, an operating handle is sleeved on the upper part of the center column, a plurality of horizontal connecting rods are evenly connected to the side of the connecting disk, a plurality of sliders are slidably connected to the horizontal connecting rods, a cable winding column is connected to the front end of the slider, the upper part of the slider is rotatably connected to one end of the oblique connecting rod, and the other end of the oblique connecting rod is rotatably connected to the lower surface of the operating handle.

[0009] Furthermore, when the operating handle moves upward, the slider is driven to move inward on the horizontal connecting rod through the oblique connecting rod, thereby driving the cable winding column to move inward;

[0010] When the operating handle moves downward, the sliding block is driven to move outward on the horizontal connecting rod through the oblique connecting rod, thereby driving the cable winding column to move outward.

[0011] Furthermore, a positioning pin is provided on the operating handle, and the positioning pin can fix the operating handle on the center column.

[0012] Furthermore, a spring is sleeved on the outer side of the center column between the operating handle and the connecting plate.

[0013] Furthermore, it also includes a winding device control box, which is electrically connected to the motor and the lifting cylinder.

[0014] Furthermore, the winding device control box controls the variable frequency operation of the motor, and the winding device control box controls the rising and falling movements of the lifting cylinder.

[0015] Furthermore, the lifting cylinder is arranged below the horizontal connecting rod and the adjacent horizontal connecting rod.

[0016] Furthermore, the winding device control box is arranged on the side of the winding device frame.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The present invention controls the motor by a frequency converter to drive the winding mechanism to rotate synchronously, thereby solving the problem of manual rotation and winding cable efficiency. The motor operating frequency can be adjusted by the frequency converter, and the motor rotation can be controlled by jog, making the cable winding operation more flexible.

[0019] The winding device of the present invention is a vertical structure, and during the rotation of the winding mechanism, the winding mechanism is evenly stressed, thereby solving the problem that the horizontal winding device is prone to tilt downward due to stress.

[0020] The winding mechanism of the present invention does not have a screw structure, and the connecting rod in the winding mechanism can be more conveniently expanded and retracted, thereby solving the problem of inconvenience in manually repeatedly operating the winding mechanism and controlling the expansion and retraction of the connecting rod.

[0021] The connecting rod in the winding mechanism of the present invention is a vertical structure without a connecting rod inclined outward, so that the wound cable is easier to lift, thus solving the problem that the cable is inconvenient to lift upward from the winding mechanism.

[0022] By adopting the present invention, during the process of lifting the cable from the winding mechanism, the cable is lifted upward by the cylinder, thereby solving the problem of manual operation of lifting the cable upward, reducing the workload and improving the efficiency of offline preparation.

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0035] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0037] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0038] like Figure 1-7 As shown, the present invention provides a large-line cable inching winding device, including a winding mechanism 1, a reducer 2, a lifting cylinder 3 and a motor 4; the winding mechanism 1, the reducer 2 and the motor 4 are sequentially connected from top to bottom, and the lifting cylinder 3 is arranged below the horizontal connecting rod 13 and the adjacent horizontal connecting rod 13. The winding mechanism 1 is arranged on the winding device workbench 5, the upper part of the lifting cylinder 3 protrudes from the winding device workbench 5, and the lower part of the winding device workbench 5 is connected to the upper part of the winding device frame 8 through the workbench adapter plate 6, the reducer 2 and the motor 4 are arranged inside the winding device frame 8, the lifting cylinder 3 is arranged in the lifting cylinder fixing frame 9, and the lifting cylinder fixing frame 9 is arranged on the side of the winding device frame 8.

[0039] The winding mechanism 1 includes a connecting disk 12, the lower part of which is connected to the reducer 2, a central column is fixed at the center of the upper surface of the connecting disk 12, an operating handle 11 is sleeved on the upper part of the central column, a plurality of horizontal connecting rods 13 are connected to the side of the connecting disk 12 at equal intervals, a plurality of sliders 14 are slidably connected to the horizontal connecting rod 13, a cable winding column 15 is connected to the front end of the slider 14, the upper part of the slider 14 is rotatably connected to one end of the oblique connecting rod 16, and the other end of the oblique connecting rod 16 is rotatably connected to the lower surface of the operating handle 11. When the operating handle 11 moves upward, the slider 14 is driven to move inward on the horizontal connecting rod 13 through the oblique connecting rod 16, thereby driving the cable winding column 15 to move inward; when the operating handle 11 moves downward, the slider 14 is driven to move outward on the horizontal connecting rod 13 through the oblique connecting rod 16, thereby driving the cable winding column 15 to move outward. A spring 10 is sleeved on the outer side of the central column between the operating handle 11 and the connecting disk 12. The operating handle 11 is provided with a positioning pin, and the positioning pin can fix the operating handle 11 on the center column.

[0040] The winding device control box 7 is electrically connected to the motor 4 and the lifting cylinder 3. The winding device control box 7 controls the motor 4 to operate at a variable frequency, and the winding device control box 7 controls the lifting cylinder 3 to rise and fall. The winding device control box 7 is arranged on the side of the winding device frame 8.

[0041] The present invention can realize the inching operation of the motor through the control of the frequency converter. That is, the motor 4 runs when the switch is pressed, and stops when the switch is released. The operating frequency of the motor 4 can be adjusted by the frequency converter. This winding device with inching operation of the motor is more flexible in controlling the operation when the cable is coiled according to different cable down-line lengths. The winding device is an upright structure, the motor 2 is installed inside the winding device frame 8, and the winding mechanism 1 is installed on the top of the winding device frame 8. The motor 4 is connected to the winding mechanism 1 through the reducer 2, and the motor 4 can realize synchronous operation with the winding mechanism 1 when it runs. The connecting rod in the winding mechanism 1 can be controlled to expand and contract. That is, when the cable is coiled, the connecting rod in the winding mechanism 1 is in an expanded state; when the cable is coiled, the connecting rod in the winding mechanism 1 is in a contracted state. When the cable is coiled and the connecting rod in the winding mechanism 1 is in a contracted state, the coiled cable can be lifted up by the lifting cylinder 3 in the winding device. After the cable is taken out, the lifting cylinder 3 descends to the initial position. With the help of the lifting cylinder, the cable can be easily and quickly taken out from the winding mechanism, which improves the efficiency of offline preparation.

[0042] The winding mechanism 1 is installed on the reducer 2, and the connecting rod in the winding mechanism 1 can be expanded and retracted. When the cable is wound, the winding mechanism is expanded; after the cable winding is completed, the winding mechanism is retracted. The central column of the winding mechanism 1 is installed with a spring 10. In the initial state, the spring 10 vertically pushes up the operating handle 11. The operating handle 11 is linked with the connecting rod in the winding mechanism 1, and the connecting rod in the winding mechanism 1 is retracted when the operating handle 11 moves upward. When the operating handle 11 is pressed vertically downward, the spring 10 is compressed, and the connecting rod in the winding mechanism 1 is linked with the operating handle 11 to expand. The positioning pin 17 in the operating handle 11 can be fixed with the central column of the winding mechanism 1, and the connecting rod in the winding mechanism 1 is always in an expanded state. When the connecting rod needs to be retracted, just press the operating handle 11, and the positioning pin 17 in the operating handle pops out, and the positioning pin 17 and the central column of the winding mechanism are in a non-fixed state. Under the upward force of the spring 10, the operating handle 11 automatically moves upward, and the connecting rod is retracted when the operating handle 11 moves upward. The reducer 2 is connected to the motor 4. When the motor 4 is running, it drives the reducer 2 and the winding mechanism 1 to rotate synchronously, and the cable is wound during the rotation of the winding mechanism 1. The winding device control box 7 can control the motor 4 to operate at a variable frequency and control the lifting cylinder 3 to rise and fall. The lifting cylinder 3 is installed on the side of the winding device frame 8 through the lifting cylinder fixing frame 9.

[0043] After the cable is wound, the winding device control box 7 controls the lifting cylinder 3 to rise. When the lifting cylinder 3 rises, the cable is automatically lifted. After the cable is taken out, the winding device control box 7 controls the lifting cylinder 3 to descend to the initial position. The lifting cylinder 3 can replace manual operation to lift the cable from the winding device, reducing the operator's workload and improving efficiency.

[0044] The present invention can improve production efficiency and solve practical problems. The winding device is controlled by a frequency converter, and can be adjusted by the frequency converter to achieve 0-50Hz control of the motor operating frequency in the winding device, thereby improving the cable winding speed. In addition, the lifting cylinder in the winding device can lift up the wound cable, replacing manual operation to lift the cable. For example, when the length of the 120mm2 large-line cable of a subway vehicle is 35m, the cable weight is about 50kg. It is time-consuming and laborious to lift the cable from the winding device manually. Using a lifting cylinder to lift the cable can not only reduce the operator's work intensity, but also improve the efficiency of the large-line cable preparation.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
