Furthermore, by employing four cable laying assemblies, the entire cable reel can be lifted, lowered, and rotated simultaneously. Moreover, because this embodiment utilizes a component-based collaborative working logic, a single integrated cable reel laying device is no longer required, greatly facilitating transportation.

Description

Technical Field

[0001] This application relates to the field of cable equipment, and in particular to a cable laying assembly. Background Technology

[0002] In cable laying projects in complex terrain and space-constrained areas, the limitations of traditional integrated cable laying machines are becoming increasingly apparent. Due to their large size, these machines rely entirely on specialized vehicles for transportation, require cranes to hoist the cable reels onto the equipment during operation, and have stringent requirements for ground flatness. These multiple factors combined not only significantly increase the cost of placing the equipment in complex terrain but also directly lead to a substantial decrease in construction efficiency. Utility Model Content

[0003] This application aims to provide a cable laying assembly that can reduce the requirements for terrain, space, and auxiliary equipment during the cable laying process.

[0004] A cable laying assembly according to an embodiment of this application includes: Base; The main lifting arm is rotatably mounted on the base, and the plane of rotation is perpendicular to the plane of the base. A roller mechanism is provided on the main lifting arm, and the rotation plane of the roller mechanism is parallel to the rotation plane of the main lifting arm; A telescopic device is provided on the base. The telescopic device is used to adjust the rotation angle of the main lifting arm in order to adjust the height of the roller mechanism.

[0005] The cable laying assembly of this application embodiment can realize the lifting and lowering control of the roller mechanism, thereby enabling unilateral lifting and lowering operation and rotational support of one side of the cable reel. Furthermore, by using four cable laying assemblies, the lifting and lowering control and rotational support of the entire cable reel can be achieved collectively. Moreover, because this application embodiment uses a component collaborative working logic, it eliminates the need for an integral cable reel laying device, greatly facilitating transportation. Simultaneously, because it can lift the cable reel from the ground, it also eliminates the reliance on cranes, better adapting to laying in complex terrain and space-constrained areas.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0012] In the description of this application, it should be noted that, unless otherwise explicitly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0013] The technical solution of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this application, not all embodiments.

[0014] See Figures 1 to 4 As shown, one embodiment of this application provides a cable laying assembly, which includes: Base 100; The main lifting arm 200 is rotatably mounted on the base 100, and the plane of rotation is perpendicular to the plane where the base 100 is located; A roller mechanism 300 is mounted on the main lifting arm 200, and the rotation plane of the roller mechanism 300 is parallel to the rotation plane of the main lifting arm 200. Telescopic device 400 is mounted on base 100. Telescopic device 400 is used to adjust the rotation angle of main lifting arm 200 in order to adjust the height of roller mechanism 300.

[0015] In this embodiment, the lifting and lowering control of the roller mechanism 300 can be realized, thereby enabling unilateral lifting and lowering operations and rotational support on one side of the cable reel 800. Furthermore, by employing four cable laying components, the lifting, lowering, and rotational support of the entire cable reel 800 can be achieved collaboratively. Moreover, because this embodiment uses a component-based collaborative working logic, an integrated cable reel laying device is no longer required, greatly facilitating transportation. Simultaneously, because the cable reel 800 can be lifted from the ground, reliance on cranes is eliminated, allowing for better adaptation to complex terrain and space-constrained areas.

[0016] The aforementioned base 100 can be placed horizontally on the ground. The base 100 can be equipped with components for transport by forklifts or other transport equipment, facilitating flexible transport. Specifically, it can be designed for direct lifting by forklifts, or for lifting using small lifting tools such as hoists, or a combination of multiple structures to improve applicability.

[0017] The aforementioned main lifting arm 200 rotates in the direction of approaching and moving away from the base 100, which is intended to allow the roller mechanism 300 to be height-adjusted to achieve lifting and rotational support for the cable reel 800.

[0018] The roller mechanism 300 described above may include rollers and bearings supporting the rollers, with the bearings mounted on the main lifting arm 200. It is understood that the rollers need to maintain sufficient width so that the rim of the cable reel 800 can be placed on the rollers.

[0019] The aforementioned telescopic device 400 is positioned between the base 100 and the main lifting arm 200, enabling it to extend and retract, thus allowing the main lifting arm 200 to rotate and adjust the height of the rollers. The telescopic device 400 can be implemented in various ways; for example, it can be an electric telescopic device 400 or a hydraulic telescopic device 400, etc. Many devices are available to achieve telescopic movement, allowing for flexible selection based on actual needs.

[0020] The aforementioned cable laying assembly needs to be used in combination. For example, four cable laying assemblies can be used to lift the flange of the cable reel 800 to complete the lifting and rotation support of the cable reel 800.

[0021] For details, please refer to Figure 4 When the cable laying assembly is needed, it can be transferred to the rim of the cable reel 800 and abut against the rim. The roller mechanism 300 is perpendicular to the rim. The four cable laying assemblies abut against the rims on both sides of the cable reel 800, and the two cable laying assemblies on the same side are arranged opposite each other. Then, the four telescopic devices 400 are controlled to lift synchronously, which can lift the cable reel 800. After that, the cable reel 800 is driven to rotate to realize the cable laying and winding operation.

[0022] It should be noted that the operation of driving the cable reel 800 to rotate can be achieved by an external cable reel rotation drive device. For example, the rotation drive can be completed by using an external friction drive wheel to abut against the rim of the cable reel 800. Alternatively, other drive transmission devices such as chain drive can be used to complete the drive. Alternatively, the roller mechanism 300 can be directly driven by pairing a drive device 700 with at least one roller mechanism 300 in the cable laying assembly, thereby directly using the roller mechanism 300 to complete the active drive of the cable reel 800.

[0023] Understandably, when it is necessary to use four cable laying assemblies to lift the cable reel 800 in a coordinated manner, the lifting operation of the cable reel 800 can be completed by manual adjustment one by one or by multiple people coordinating the adjustment. Alternatively, the four cable laying assemblies can be connected to an external control system 900, and electronic lifting control can be achieved by setting up sensors to detect the tilt and height of the cable reel 800. For example, a height sensor can be used to detect whether the cable reel 800 has reached a certain height to determine whether it can be rotated, and a tilt sensor can be used to detect the degree of tilt so that the four cable laying assemblies can be lifted synchronously to prevent the cable reel 800 from tilting.

[0024] It should also be noted that the reference Figure 4 To prevent movement when the four cable laying assemblies work together, a connecting rod 1000 can be installed between the four cable laying assemblies. The connecting rod 1000 can be installed after all four cable laying assemblies have abutted against their respective wheel flanges.

[0025] The base 100 is provided with a combination connection part, which is used to connect two adjacent cable laying assemblies through a connecting rod 1000.

[0026] The above-mentioned combined connection part can be configured with multiple connection holes, and the two ends of the connecting rod 1000 are provided with corresponding through holes so that the connection between the base and the connecting rod can be completed by using bolt fasteners.

[0027] The core controller of the aforementioned control system 900 can be a microcontroller, DSP, PLC, etc. The specific choice can be made according to actual needs. For example, a Siemens S7 series PLC or an STM32 series processor can be selected.

[0028] In some implementations, reference Figures 1 to 3 Telescopic device 400, including: The lifting cylinder 410 has one end rotatably mounted on the base 100 and the other end rotatably connected to the main lifting arm 200. The rotation plane of the lifting cylinder 410 is parallel to the rotation plane of the main lifting arm 200. The hydraulic drive system 420 is mounted on the base 100 and is used to drive the lifting cylinder 410 to extend and retract.

[0029] The aforementioned lifting cylinder 410 needs to be rotatably connected to the base 100 and the main lifting arm 200 in order to cooperate with the rotation operation of the main lifting arm 200.

[0030] Specifically, one side of the cylinder body of the lifting cylinder 410 can be rotatably connected to the base 100, and the piston rod can be rotatably connected to the main lifting arm 200, so as to complete the rotation operation of the main lifting arm 200 by extending and retracting the piston rod. Furthermore, by adopting the configuration of the cylinder body below and the piston rod above, the center of gravity of the entire cable laying assembly can be lowered to a certain extent. It is understandable that adjusting the lifting cylinder 410 could also achieve the rotation operation of the main lifting arm 200, but this arrangement would raise the center of gravity.

[0031] The aforementioned hydraulic drive system 420 primarily provides a hydraulic power source to drive the lifting cylinder 410 to extend and retract. Specifically, the hydraulic drive system 420 may include an electric hydraulic pump, electrically controlled valves, etc. The electric hydraulic pump can be started and stopped under the control of the control system 900 or manually operated. The electrically controlled valves can inject oil into the rod chamber and rodless chamber of the lifting cylinder 410 under the operation of the control system 900 or manually operated, thereby realizing the extension and retraction of the piston rod.

[0032] The aforementioned hydraulic drive system 420 can also be equipped with a matching pressure detection unit, allowing operators to monitor the drive system's operating status in real time. Furthermore, when the hydraulic gauge has data transmission capabilities, the control system 900 can better control the lifting and lowering of the cable reel 800 by acquiring the pressure data detected by the hydraulic gauge. This reduces the occurrence of excessive oil pressure in individual cable laying assemblies and helps to balance the oil pressure as much as possible.

[0033] In some implementations, reference Figures 1 to 3 The main lifting arm 200 is configured as a “7” shaped support arm. One end of the main lifting arm 200 is hinged to the base 100, and the lifting cylinder 410 is located inside the main lifting arm 200.

[0034] In this embodiment, the use of a "7"-shaped support arm allows the entire cable laying assembly to effectively reduce its overall size while providing heavy-duty support, thus achieving a lightweight design. Furthermore, the "7"-shaped support arm facilitates the telescopic operation of the telescopic device 400 and also better supports the main lifting arm 200.

[0035] In some implementations, reference Figures 1 to 3 The base 100 is provided with two parallel slot structures 110.

[0036] In this embodiment, by setting two parallel slot structures 110, a basis for forklift equipment to insert, pick up, and transfer is provided, making it easier for operators to quickly complete the transfer operation.

[0037] In some implementations, reference Figures 1 to 3 Two slot structures 110 are located on both sides of the base 100 and are arranged perpendicularly to the roller mechanism 300.

[0038] In this embodiment, the two slot structures 110 are arranged on both sides of the base 100 and perpendicular to the roller mechanism 300. This allows the operator to better keep the center of the entire cable laying assembly in a straight line when transferring the cable laying assembly, and thus better realize the contact operation between the roller mechanism 300 and the rim of the cable reel 800 in the cable laying assembly.

[0039] In some implementations, reference Figures 1 to 3 A limiting structure 520 is provided on the base 100, and a top rod structure 510 is provided on the main lifting arm 200. The top rod structure 510 is positioned toward the limiting structure 520, and the limiting structure 520 is used to restrict the movement of the top rod structure 510 after it comes into contact with the limiting structure 520.

[0040] The aforementioned top rod structure 510 is positioned towards the limiting structure 520 on the base 100, thereby enabling support for the main lifting arm 200 when the telescopic device 400 supporting the main lifting arm 200 malfunctions. In other words, due to the presence of the top rod structure 510 and the limiting structure 520, the main lifting arm 200 can be supported when it suddenly drops, preventing accidents such as the cable reel 800 tipping over.

[0041] The aforementioned top rod structure 510 is rotatably connected to the main lifting arm 200 and is equipped with a state limiting structure. That is, the state limiting structure can limit the top rod structure 510 to a certain rotation angle, or to whether it is facing the limiting structure 520 or away from the limiting structure 520, so as to better balance the lifting operation and the fall prevention operation.

[0042] The aforementioned state restriction structure can be configured with limiting components such as pins. By opening multiple through holes in the main lifting arm 200 and the top rod structure 510, pins can be used to restrict the top rod structure 510 at different angles. Alternatively, a rotation damper can be directly selected, and damped rotational support for the top rod structure 510 can be achieved by arranging a damper at the rotation center of the top rod structure 510. A torsion spring structure can also be directly used to restrict the top rod structure 510. For example, when the torsion spring is normally deployed, the top rod structure 510 can face the limiting structure 520, and when twisted, it can move away from the limiting structure 520.

[0043] The aforementioned limiting structure 520 can be configured as multiple consecutive limiting grooves to better limit the top rod structure 510.

[0044] In some implementations, reference Figures 1 to 3 The main lifting arm 200 is configured as a “7” shaped support arm, and the top rod structure 510 is located on the inner side of the main lifting arm 200.

[0045] In this embodiment, when the main lifting arm 200 is configured as a "7"-shaped support arm, placing the top rod structure 510 on the inner side of the main lifting arm 200 can better enable the top rod structure 500 to perform emergency support operations.

[0046] In some implementations, reference Figures 1 to 3The main lifting arm 200 is equipped with a cable reel protective frame 600.

[0047] In this embodiment, adding a cable reel protective frame 600 can improve the safety during the deployment process to a certain extent.

[0048] In some implementations, reference Figures 1 to 3 The cable reel protective frame 600 includes: The protective bracket 610 is installed on the main lifting arm 200; The protective wheel 620 is mounted on the protective bracket 610 and located above the main lifting arm 200.

[0049] The aforementioned protective bracket 610 is mainly used to support the protective wheel 620. After the protective bracket 610 is deployed, the protective wheel 620 will be located above the roller mechanism 300 and further away from the rim of the cable reel 800 than the roller mechanism 300, so as to achieve the purpose of protection.

[0050] In some implementations, reference Figures 1 to 3 The protective bracket 610 is rotatably mounted on the main lifting arm 200, and the plane of rotation is parallel to the plane of rotation of the main lifting arm 200. The main lifting arm 200 is provided with a rotation adjustment limit part 210, which is used to limit the protective bracket 610 to different rotation angles.

[0051] The aforementioned rotation adjustment limit part 210 can adjust the rotation angle of the protective bracket 610, thereby allowing the protective bracket 610 to better adapt to cable reels 800 of different specifications.

[0052] In some implementations, reference Figures 1 to 3 The rotation adjustment limit part 210 includes a plurality of first limit through holes provided on the main lifting arm 200, and the protective bracket 610 is provided with at least one second limit through hole that matches the first limit through hole.

[0053] The aforementioned plurality of first limiting through holes can be arranged in a fan shape, and the geometric center of the fan shape can coincide with the rotation center of the rotation adjustment limiting part 210. Then, the second limiting through hole and any one of the first limiting through holes can be fixed by a pin to complete the adjustment of the rotation angle of the rotation adjustment limiting part 210.

[0054] In some implementations, reference Figures 1 to 3 The cable laying assembly also includes: The drive unit 700 is mounted on the main lifting arm 200 and is used to drive the roller mechanism 300 to rotate.

[0055] In this embodiment, by providing a drive device 700, the cable laying assembly can be transformed from a passive rotation support structure to an actively driven rotation structure, eliminating the need for an external drive device to rotate the cable reel 800. It should be noted that the drive device 700 can be started manually or automatically controlled by the control system 900.

[0056] Understandably, the drive unit 700 can take many forms. For example, it can use a hydraulic drive system or an electric drive system. The specific drive form can be flexibly selected as long as it can drive the cable reel 800.

[0057] In some implementations, reference Figures 1 to 3 The drive unit 700 includes a drive motor.

[0058] In this embodiment, a drive motor is directly used as the power source, which makes the drive motor control method simpler and can provide more accurate control precision.

[0059] In some implementations, reference Figures 1 to 2 The cable laying assembly also includes a hoisting component 220 mounted on the main lifting arm 200.

[0060] In this embodiment, considering that some transport vehicles are too high to be directly transported using forklift equipment, the cable laying assembly can be hoisted to the ground first using the lifting component 220, and then transported by forklift equipment.

[0061] In some implementations, reference Figures 1 to 2 The lifting component 220 is set as a lifting ring.

[0062] In this embodiment, a lifting ring structure is directly used for hoisting. The lifting ring structure is simple and easy to attach to hoisting equipment, and can adapt to hoisting needs in more scenarios.

[0063] The above are merely specific embodiments of this application. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working processes of the systems, modules, and units described above can be referred to the corresponding processes in the foregoing method embodiments, and will not be repeated here. It should be understood that the protection scope of this application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the protection scope of this application.
