Description

Technical Field

[0001] The present invention belongs to the technical field of coal mine tunnel equipment, and in particular relates to an automatic storage device for cables without power source and a mobile telescopic belt transfer machine. Background Art

[0002] The mobile telescopic belt transfer machine is a common transportation equipment, which is particularly suitable for scenes such as tunnel opening, connecting tunnels, continuous mining and continuous rushing. Due to the telescopic characteristics of the mobile telescopic belt transfer machine, when it is used in conjunction with equipment such as tunneling machines, there is a lack of corresponding cable storage technology, resulting in the accumulation of cables on the tunnel floor or manual retraction and release on the equipment. This not only restricts the tunneling capacity of the tunneling equipment, but also poses a safety hazard, which is not conducive to safe production in coal mines. Summary of the invention

[0003] The purpose of the present disclosure is to provide a non-powered automatic cable storage device and a mobile telescopic belt transfer machine to solve at least some of the problems in the prior art.

[0004] A first aspect of an embodiment of the present disclosure provides an automatic storage device for cables without a power source, the automatic storage device comprising:

[0005] The front connecting frame is connected to the secondary telescopic frame of the mobile telescopic belt loader;

[0006] The rear connecting frame is connected to the primary telescopic frame of the mobile telescopic belt transfer machine;

[0007] The rear winding cable assembly is connected to the rear connecting frame and is connected to the primary telescopic frame body of the mobile telescopic belt transfer machine through the rear connecting frame;

[0008] The front cable reel assembly is connected to the front connecting frame and is connected to the front end of the secondary telescopic frame of the mobile telescopic belt transfer machine through the front connecting frame;

[0009] A guide wheel assembly is connected to the front end of the secondary telescopic frame of the mobile telescopic belt loader;

[0010] A support frame connected to the rear cable winding assembly and the front cable winding wheel assembly, and used for supporting the rear cable winding assembly and the front cable winding wheel assembly;

[0011] An outer circular tube, one end of which is connected to the rear connecting frame;

[0012] An inner round tube, one end of which is connected to the front connecting frame, and the other end of which is inserted into the outer round tube;

[0013] The cable loops pass through the inner and outer round tubes and are randomly distributed on the inner and outer round tubes to achieve dynamic storage of the cables.

[0014] The main technical effect achieved by the disclosed embodiment is that the device realizes automatic storage and release of cables through the coordinated work of the front connecting frame, the rear connecting frame, the rear cable winding assembly, the front cable winding wheel assembly and the guide wheel assembly. Since these components are connected to the telescopic frame of the mobile telescopic belt transfer machine, the retraction and release of the cable is synchronized with the movement of the transfer machine, and no additional operation is required. This synchronous operation reduces manual intervention, thereby improving the efficiency of cable management. The cable rings are randomly distributed on the inner and outer tubes. This design makes the cables evenly stressed during storage and release, avoiding damage caused by improper pulling or stacking. The structural design of the inner and outer tubes provides a protective channel for the cables, reduces the direct contact between the cables and the surrounding environment, and reduces the risk of wear and damage. The orderly management of cables also reduces the clutter of cables in the work area, reduces the risk of operators being tripped or entangled by cables, and improves the safety of the work site.

[0015] Optionally, the rear cable winding assembly includes a sliding beam, a first pulley and a fixed plate, the sliding beam is provided with a circular hole, the first pulley is connected to the sliding beam through the circular hole via a connecting piece, and is fixed on both sides with a fixed plate, and the first pulley is used for winding the cable.

[0016] The main technical effect achieved by the embodiment of the present disclosure is: the design of the first pulley and the sliding beam in the rear cable winding assembly enables the cable to be evenly and stably wound on the pulley, reducing the risk of damage and failure during the cable winding process.

[0017] Optionally, the support frame includes a side connecting plate, a roller and a side fixing frame, one end of the roller is rotatably mounted on the side fixing frame, and the other end is rotatably mounted on the side connecting plate, and the roller is used for winding the cable.

[0018] The main technical effect achieved by the embodiments of the present disclosure is that the roller design in the support frame allows the cable to rotate flexibly during transmission, reducing friction and wear and extending the service life of the cable.

[0019] Optionally, the front cable winding wheel assembly includes a cable winding fixing frame, a second pulley and a side fixing plate, the second pulley is connected to the cable winding fixing frame through a connecting piece passing through a circular hole, and the two sides are fixed by the side fixing plates.

[0020] The main technical effect achieved by the embodiment of the present disclosure is that the design of the second pulley and the cable winding fixing frame in the front cable winding wheel assembly allows the cable to be evenly wound on the front cable winding wheel assembly, avoiding cable accumulation and damage.

[0021] Optionally, the guide wheel assembly includes a guide wheel fixing frame, a roller fixing plate and a small roller, the small roller is fixed on the roller fixing plate, and the roller fixing plate is fixed on the guide wheel fixing frame.

[0022] The main technical effect achieved by the embodiments of the present disclosure is that the design of the guide wheel assembly ensures that the cable is correctly guided during the extension and retraction process of the transfer machine, reducing the risk of cable deviation or jamming.

[0023] Optionally, two ends of the cable ring are respectively fixed between the front cable winding wheel assembly and the rear cable winding assembly to achieve dynamic storage of the cable.

[0024] The main technical effect achieved by the embodiment of the present disclosure is that the two ends of the cable ring are fixed between the front and rear cable winding wheel assemblies, ensuring that the cable can be dynamically adjusted in length when the transfer machine is extended or retracted, thereby avoiding cable accumulation or excessive stretching.

[0025] Optionally, the number of first pulley layers in the rear cable winding assembly and the number of second pulley layers in the front cable winding wheel assembly are adjusted according to the number of turns of the cable.

[0026] The main technical effect achieved by the embodiments of the present disclosure is that by adjusting the number of pulley layers, the automatic cable storage device can adapt to the storage of cables with different numbers of turns, thereby improving the adaptability and flexibility of the device.

[0027] Optionally, the change in cable length between the rear cable winding assembly and the front cable winding wheel assembly corresponds to the extension and retraction of the telescopic frame of the mobile telescopic belt transfer machine, wherein:

[0028] When the telescopic frame of the mobile telescopic belt transfer machine is extended, the rear cable winding assembly moves forward relative to the front cable winding wheel assembly, reducing the cable length between the rear cable winding assembly and the front cable winding wheel assembly, thereby realizing cable storage;

[0029] When the telescopic frame of the mobile telescopic belt transfer machine is retracted, the rear cable winding assembly moves backward relative to the front cable winding wheel assembly, increasing the cable length between the rear cable winding assembly and the front cable winding wheel assembly, thereby achieving the release of the cable.

[0030] The main technical effect achieved by the embodiment of the present disclosure is that through the relative movement of the rear cable winding assembly and the front cable winding wheel assembly, the cable length changes synchronously with the extension and contraction of the transfer machine telescopic frame, ensuring that the cable will not be damaged due to excessive stretching or accumulation.

[0031] Optionally, the movement of the rear cable assembly is directly caused by the extension and retraction of the primary telescopic frame of the mobile telescopic belt transfer machine, wherein:

[0032] The rear cable assembly is connected to the first telescopic frame of the mobile telescopic belt transfer machine, so that when the first telescopic frame performs telescopic action, the rear cable assembly moves synchronously therewith;

[0033] The front cable reel assembly is fixed on the secondary telescopic frame of the mobile telescopic belt transfer machine to keep its position relatively stable;

[0034] The cable ring is retracted and released between the rear cable winding assembly and the front cable winding wheel assembly, which is achieved by the relative movement between the rear cable winding assembly and the front cable winding wheel assembly.

[0035] The main technical effect achieved by the embodiment of the present disclosure is that the movement of the rear cable assembly is directly caused by the primary telescopic frame of the transfer machine, without the need for an additional power source, thereby reducing energy consumption and maintenance costs, while improving the ease and safety of operation.

[0037] The main technical effect achieved by the embodiments of the present disclosure is: integrating the automatic storage device for non-powered cables into the mobile telescopic belt transfer machine, so that the transfer machine can effectively manage and protect the cables in various working environments, thereby improving the practicability and market competitiveness of the equipment.

[0047] like Figure 1-2As shown, the embodiment of the present disclosure provides a non-powered cable automatic storage device and a mobile telescopic belt transfer machine 10, wherein the non-powered cable automatic storage device is mounted on the mobile telescopic belt transfer machine 10.

[0048] The device realizes automatic storage and release of cables through the coordinated work of the front connecting frame, the rear connecting frame 9, the rear cable winding assembly 1, the front cable winding wheel assembly 3 and the guide wheel assembly. Since these components are connected to the telescopic frame of the mobile telescopic belt transfer machine 10, the retraction and release of the cables are synchronized with the movement of the transfer machine, and no additional operation is required. This synchronous operation reduces manual intervention, thereby improving the efficiency of cable management. The cable rings 6 are randomly distributed on the inner circular tube 7 and the outer circular tube 8. This design makes the cables evenly stressed during storage and release, avoiding damage caused by improper pulling or stacking. The structural design of the inner circular tube 7 and the outer circular tube 8 provides a protective channel for the cables, reduces the direct contact between the cables and the surrounding environment, and reduces the risk of wear and damage. The orderly management of cables also reduces the disorder of cables in the work area, reduces the risk of operators being tripped or entangled by cables, and improves the safety of the work site.

[0049] The rear cable assembly 1 is composed of a sliding beam 11, a first pulley 12, and a fixing plate 13. Figure 3 As shown, a pin is passed through the circular holes on the first pulley 12 and the sliding beam 11, and fixed on both sides with fixing plates 13, and then the pin and the fixing plates 13 are fastened with screws to ensure that the first pulley 12 can rotate flexibly.

[0050] The support frame 2 is composed of a side connecting plate 21, a roller 22 and a side fixing frame 23. Figure 4 As shown, one end of the roller 22 passes through the round hole on the side fixing frame 23, and the other end passes through the round hole on the side connecting plate 21, and the roller shaft is fixed with bolts to ensure that the roller can rotate flexibly.

[0051] The front cable reel assembly 3 is composed of a cable reel fixing frame 31, a second pulley 33 and a side fixing plate 32. Figure 5 As shown, a pin is passed through the round holes on the second pulley 33 and the cable fixing frame 31, and the two sides are fixed with side fixing plates 32, and then the pin and the side fixing plates 32 are fastened with screws to ensure that the second pulley 33 can rotate flexibly.

[0052] The guide wheel assembly 4 is composed of a guide wheel fixing frame 41, a roller fixing plate 42 and a small roller 43. Figure 6 As shown, the small roller 43 is fixed to the roller fixing plate 42 by bolts, and the roller fixing plate 42 is fixed to the guide wheel fixing frame 41 by bolts.

[0053] Workflow:

[0054] The cable is connected from the power line of the underground tunnel, passes through the cable ring 6 with a telescopic round tube of the mobile telescopic belt transfer machine 10, then passes through the lower side of the telescopic transfer machine, and then passes through the sliding beam 11 of the rear cable winding assembly 1, is wound around the pulley 12 between the rear cable winding assembly 1 and the front cable winding wheel assembly 3, and then passes through the guide wheel assembly to the front lap joint device. When the telescopic frame of the mobile telescopic belt transfer machine 10 is extended, the telescopic frame drives the rear cable winding assembly 1 forward. Since the front cable winding wheel assembly 3 is fixed, the length of the cable between the rear cable winding assembly 1 and the front cable winding wheel assembly 3 is reduced. At the same time, the front connecting frame on the other side is also extended with the frame, and the cable gradually changes from a U-shape to a horizontal state, and the length of the stored cable is reduced. The cable length reduced by the cable storage device on both sides of the mobile telescopic frame is equal to the extended length of the frame; conversely, when the telescopic frame is retracted, the cable length increased by the cable storage device on both sides of the mobile telescopic frame is equal to the contracted length of the frame, thereby realizing the storage of the cable.

[0055] It should be noted that when the number of telescopic frames of the mobile telescopic belt transfer machine is an even number, only the cable storage device composed of the rear cable winding assembly 1, the support frame 2, the front cable winding wheel assembly 3, and the guide wheel assembly 4 needs to be used. The number of cables wound between the rear cable winding assembly 1 and the front cable winding wheel assembly 3 is an even number, and the length of the mobile telescopic belt transfer machine extended (or contracted) is consistent with the number of cables reduced (or increased) between the front cable winding wheel assembly 3 and the rear cable winding assembly 1; when the number of telescopic frames of the mobile telescopic belt transfer machine is an odd number, the cables need to be wound according to the workflow, and the length of the cables stored between the cable rings 6 is equal to the telescopic distance of the first-level telescopic arm.

[0056] The above are only preferred embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure should be included in the scope of protection of the present disclosure.
