Description

Technical Field

[0001] This utility model belongs to the field of cable winding and unwinding technology, specifically relating to a communication cable winding and unwinding device for railway communication engineering. Background Technology

[0002] In railway transportation production and construction, various communication methods are used for the transmission and processing of various information. Railway communication focuses on transportation production, and its main function is to realize the unified scheduling and command of train operation and locomotive and rolling stock operations. However, due to the dispersed nature of railway lines, numerous branch lines, and diverse business types, it is difficult to form a unified communication system. In order to command trains in operation, wired communication must be used. Therefore, railway communication must combine wired and wireless communication and adopt multiple communication methods. Currently, the existing wire laying usually requires the use of wire laying devices.

[0003] For example, Chinese Patent Publication No. CN222647342U discloses a communication cable winding and unwinding device for railway communication engineering, which includes a winding mechanism. The winding mechanism includes a winding motor, and the output end of the winding motor is fixedly connected to a rotating shaft. A solid connecting rod also drives the winding plate to rotate, winding up the cable at the top of the winding plate. When it is necessary to control the diameter of the wound cable, the device controls the operation of a telescopic cylinder. The telescopic cylinder drives a limiting ring to move on the rotating shaft, and a sliding column drives a hollow connecting rod to move. Under the action of the limiting connecting rod, the hollow connecting rod is limited to only moving the winding plate up and down, thereby controlling the diameter of the wound cable. By using the winding mechanism, the size of the wound cable can be adjusted according to the winding requirements.

[0004] As described in the prior art of the aforementioned patent, when the wire spool is placed on or unloaded from the winding device, it needs to be installed by hoisting. When laying the wire, cranes and other equipment are required. Sometimes the construction area is narrow, and too much equipment is difficult to deploy. Utility Model Content

[0005] The purpose of this invention is to provide a communication cable winding and unwinding device for railway communication engineering, which can place the cable roll into the winding equipment by means of a lifting method, making it convenient to install the cable roll during the unwinding process.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] A communication cable retraction device for railway communication engineering includes a car body and a movable plate. One end of the car body and one end of the movable plate are hinged together via a hinge point. A guide rod is installed on the movable plate, and a movable rod is slidably disposed on the guide rod. A receiving plate is fixedly installed on the movable rod, and an insert rod is installed on the receiving plate. A telescopic rod is installed at the lower end of the car body, and the telescopic end of the telescopic rod is hinged to the movable plate.

[0008] In a preferred embodiment, the vehicle body is provided with four casters at its lower corners, and the casters are omnidirectional wheels.

[0009] In a preferred embodiment, the two ends of the movable rod are slidably connected to the guide rod, and the middle section of the movable rod is connected to a lead screw via a threaded engagement, with a drive motor provided at one end of the lead screw.

[0010] In a preferred embodiment, the central axis of the receiving plate coincides with the central axis of the insertion rod.

[0011] In a preferred embodiment, the vehicle body has a mounting hole at the end away from the hinge point for mounting a counterweight mechanism.

[0012] In a preferred embodiment, the counterweight mechanism includes a counterweight block, one end of which is provided with a socket, and the other end of which is provided with a plug for insertion into a mounting hole or socket.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model is used when laying out coils. The movable plate is adjusted to a vertical position, and then the height of the insertion rod is adjusted so that the height of the insertion rod is the same as the height of the center hole of the coil. Then, the insertion rod is aligned with the center hole of the coil and the vehicle body is pushed to drive the insertion rod into the center hole of the coil. Then, the movable plate is adjusted from a vertical position to a horizontal position, so that the coil can be lifted onto the movable plate and placed on the directional device. This avoids the cumbersome process of manual handling or hoisting with a lifting device and also achieves the purpose of placing the coil on the placement rack.

[0015] The vehicle body of this utility model is also equipped with counterweights, and the counterweights can be flexibly disassembled and installed on the vehicle body. The number of counterweights can be increased or decreased according to the size of the coil to be installed, making the use of the device more flexible. Attached Figure Description

[0023] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Please see the appendix Figures 1 to 3 As shown, this utility model provides a communication cable winding and unwinding device for railway communication engineering, including a car body 1 and a movable plate 2. One end of the car body 1 and one end of the movable plate 2 are hinged together through a hinge point 22. A guide rod 3 is installed on the movable plate 2, a movable rod 4 is slidably arranged on the guide rod 3, a receiving plate 5 is fixedly installed on the movable rod 4, and an insert rod 6 is installed on the receiving plate 5. A telescopic rod 21 is installed at the lower end of the car body 1, and the telescopic end of the telescopic rod 21 is hinged to the movable plate 2.

[0027] In this device, when placing the cable, the coil needs to be laid flat so that the insert rod 6 can be inserted into the center hole of the coil, and the coil can be lifted and placed on the device for cable feeding. To adjust the cable feeding device, first unfold the movable plate 2 so that the movable plate 2 is in a vertical state, and then adjust the insert rod 6 up and down so that the height of the insert rod 6 is the same as the center hole of the coil. Then push the vehicle body 1 so that the insert rod 6 is aligned with the center hole of the coil and inserted. Then slowly adjust the movable plate 2 from a vertical state to a horizontal state. During the state change of the movable plate 2, the coil can be lifted onto the movable plate 2 for placement, so that cable feeding can be carried out.

[0028] In this embodiment, the vertical unfolding or horizontal lowering of the movable plate 2 and the vehicle body 1 is mainly achieved by rotating around the hinge point 22, and the extension and retraction of the telescopic rod 21 is used as the power to drive the movable plate 2 to rotate.

[0029] The lower four corners of the vehicle body 1 are respectively provided with movable wheels 11, and the movable wheels 11 are omnidirectional wheels;

[0030] The movable wheels 11 at the bottom of the vehicle body 1 facilitate the mobility of the device and enable positional adjustment between it and the coil.

[0031] The two ends of the movable rod 4 are slidably connected to the guide rod 3, and the middle section of the movable rod 4 is connected to the lead screw 41 by thread engagement. One end of the lead screw 41 is equipped with a drive motor 42, and the central axis of the receiving plate 5 is set to coincide with the central axis of the insertion rod 6.

[0032] Please participate Figure 1 and Figure 3 As shown, the up-and-down movement of the insertion rod 6 is achieved by the drive motor 42 driving the lead screw 41 to rotate. The screw 41 and the movable rod 4 are engaged by the thread, which drives the rod to move. Since the receiving plate 5 is fixed on the movable rod 4 and the insertion rod 6 is fixed on the receiving plate 5, the movement of the movable rod 4 drives the insertion rod 6 to move up and down, so that the insertion rod 6 can be aligned with the center hole of the coil.

[0033] Please see Figure 4 As shown, the vehicle body 1 has a mounting hole 12 for mounting a counterweight mechanism 7 at one end away from the hinge point 22. The counterweight mechanism 7 includes a counterweight block 71, one end of which is provided with an insertion port 73, and the other end of which is provided with an insertion block 72 for inserting into the mounting hole 12 or the insertion port 73.

[0034] In order to maintain the stability of the vehicle body 1 during the process of lifting the coil, a counterweight mechanism 7 is set at the other end of the vehicle body 1 to prevent the vehicle body 1 from tilting when lifting the coil. Moreover, the counterweight mechanism 7 can be disassembled from the vehicle body 1, and the counterweight mechanisms 7 can be connected to each other, so as to increase or decrease the number of counterweight mechanisms 7 according to the specific use, making the use of the equipment more flexible.

[0035] Specifically, in use, the insert block 72 of the counterweight mechanism 7 is aligned with the mounting hole 12 on the vehicle body 1 and inserted to complete the assembly between the counterweight mechanism 7 and the vehicle body 1. When more counterweight mechanisms 7 need to be added, the insert block 72 of the added counterweight mechanism 7 can be inserted into the insert 73 of the counterweight mechanism 7 already placed on the vehicle body 1 and inserted. In this way, the number of counterweight blocks 71 in the counterweight mechanism 7 is increased, thereby increasing the stability of the equipment during use.

[0036] In addition, in this application, the telescopic rod 21 is an electric telescopic rod, and the drive motor 42 is a servo motor. The telescopic rod 21 and the drive motor 42 are jointly controlled by a control device. The control device can be fixedly installed on the vehicle body 1 or handheld. Moreover, the control method of the control device for the drive motor 42 and the telescopic rod 21 is existing technology, which will not be described in detail here.

[0037] The working principle of this utility is as follows: When laying the cable, the coil needs to be laid flat so that the insert rod 6 can be inserted into the center hole of the coil, and the coil can be lifted and placed on the device for cable laying. To adjust the cable laying device, first unfold the movable plate 2 so that the movable plate 2 is in a vertical position, and then adjust the insert rod 6 up and down so that the height of the insert rod 6 is the same as the center hole of the coil. Then push the carriage 1 so that the insert rod 6 is aligned with the center hole of the coil and inserted. Then slowly adjust the movable plate 2 from a vertical position to a horizontal position. During the state change of the movable plate 2, the coil can be lifted onto the movable plate 2 for placement, thereby enabling cable laying.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
