Description

Technical Field

[0001] This invention relates to the field of power construction equipment and cable laying technology, specifically to a device and its operating method for lifting and guiding cable reels of different sizes into the cable laying position during cable laying in power engineering. Background Technology

[0002] Cable laying devices used in power construction support and guide cable reels during the laying process. Traditional cable laying frames typically employ the following design:

[0003] 1. Central shaft design: The cable reel needs to be mounted on a central shaft consisting of an inner core shaft and an outer ring shaft connected by bearings. This design has drawbacks such as cumbersome installation and disassembly, limitations in bearing size selection, and high maintenance frequency.

[0004] 2. Wire reel guiding method: The wire reel needs to be hoisted to the designated position on the wire feeding frame with the help of external mechanical equipment such as cranes. The operation is rough and there are safety hazards.

[0005] 3. Lifting Mechanism: A screw jack or hydraulic lifting system is typically used to lift the cable reel mounted on the shaft to a suitable working height. This design requires significant power, resulting in high energy consumption. Furthermore, stability may be compromised once the reel is completely off the ground.

[0006] 4. Limited mobility: Some designs include mobility mechanisms, but their range of motion is limited and their mobility is insufficient.

[0007] For example, Chinese utility model patent CN220223112U discloses a wire feeding frame that is easy to load and unload, which is equipped with a moving mechanism, a winding shaft lifting mechanism and a limiting mechanism to facilitate the loading and unloading of the wire spool and height adjustment.

[0008] The applicant's prior utility model patent CN213923485U uses a structure of studs, top pressure blocks, and lead screw pressure blocks to fix the coil.

[0009] Chinese invention patent application CN117446603A discloses a power construction wire winding and laying device, including a winding and laying assembly, a drive assembly, a guide assembly, and a winding and laying frame, etc., which can adjust the height of the winding and laying frame and realize actions such as rolling out.

[0010] In summary, existing cable laying devices have many shortcomings in their structural design, such as cumbersome installation and disassembly of the cable reel, potential risks in the guiding method, high energy consumption, poor stability, and limited flexibility, which restrict their practicality, safety, and efficiency.

[0011] Therefore, it is necessary to thoroughly innovate the design of traditional cable laying devices, simplify the installation and disassembly process of the cable reel, adopt safer and more efficient guiding methods, improve the load-bearing stability of the device, enhance its mobility, and reduce energy consumption, so as to comprehensively improve its practical performance and operational efficiency. Summary of the Invention

[0012] In view of this, the present invention provides an efficient, flexible, and safe cable laying device and its guiding method. Through innovative design, it achieves efficient introduction, stable stopping, and labor-saving lifting of cable reels of different specifications, significantly improving the efficiency and economy of power construction.

[0013] The technical solution of this invention is implemented as follows: A cable laying device for power construction, comprising:

[0014] A frame structure device is provided; a cable feeding station is located in the lower internal area of ​​the frame structure; two parallel cable reel guide rollers are used to guide the two reels of the cable to the cable feeding station; a slide rail is installed in the lower part of the frame structure and is used to install and guide the two cable reel guide rollers; a roller winding machine is located above the frame structure, the width of the traction belt of the roller winding machine is not greater than the width of the cable storage section of the cable reel, and the traction belt is arranged in a loop around the cable storage section. The advantages are: by using a frame structure device and two cable reel guide rollers, a simplified and efficient cable feeding device is provided, which can adapt to cable reels of different diameters and ensure their smooth feeding to the cable feeding station.

[0015] Preferably, the two cable reel guide rollers have a consistent downward-concave arc section at the cable feeding station. This concave arc section forms a stable support and stopping position for the cable reel. The beneficial effect is that the specially designed downward-concave arc section provides a stable support and stopping position in the cable reel guide rollers, enhancing the stability of the cable reel at the cable feeding station and preventing rolling or displacement.

[0016] Preferably, the smooth continuation of the concave arc segment is an inclined straight segment, which slopes gently relative to the device frame from far to near, guiding the cable reel to its stopping position smoothly. The beneficial effect is that the smooth continuation of the arc segment to the inclined straight segment creates a gently sloping guide path, facilitating the smooth rolling of the cable reel into the stopping position, reducing wear on the cable reel and the device, and extending its service life.

[0017] Preferably, the slide rails are a pair, including a first slide rail and a second slide rail. The first slide rail is located at the near end of the straight section and can be separated from the spool guide roller at any time. The second slide rail is located at the far end of the straight section and is hinged to the spool guide roller by a sleeve connection. The advantages are: the pair of slide rails located at the near and far ends of the straight section, combined with the separable and hinged design, facilitates convenient installation, adjustment, and disassembly of the spool guide roller, improving operational efficiency.

[0018] Preferably, the two slide rails are further provided with sliding support seats, which are arranged in pairs, each located on the side of its corresponding spool guide roller away from the center of the device frame. The advantages are: providing paired support seats on the slide rails to support the winding shaft, effectively distributing the load, reducing pressure on the spool guide roller, preventing deformation, and simultaneously improving the load-bearing capacity and stability of the entire device.

[0019] Preferably, the surrounding path includes the following arrangement:

[0020] One end of the traction belt is fixed on the upper part of the device frame, away from the straight section;

[0021] A first transition roller is provided at a position on one side of the concave arc segment of the guide roller track for the two reels and relatively close to the straight segment.

[0022] A second transition roller is provided at the lower part of the device frame near the junction of the straight section and the concave arc section.

[0023] On the upper part of the device frame, near the straight section, an active roller connected to the power source is installed. The beneficial effect is that the design of the surrounding path, including a fixed traction belt end, a transition roller, and an active roller connected to the power source, ensures that the traction belt can smoothly surround the cable storage section, forming a closed traction loop and optimizing power transmission efficiency.

[0024] Preferably, the traction belt forms a break between the drive roller and the second transition roller, and this break is temporarily joined by a detachable connector. The advantage is that the detachable connector at the break between the drive roller and the second transition roller allows the traction belt to be converted into a power drive belt for lifting the spool and guiding it onto the roller track when needed, increasing the equipment's versatility and reducing the need for additional components.

[0025] A method for guiding a cable reel into a work station includes the following steps:

[0026] S1 adjusts the spacing between the two cable reels entering the raceway to match the diameter of the cable reel used.

[0027] S2 fixes one end of the traction belt on the upper part of the device frame, away from the straight section of the wire reel;

[0028] S3 wraps the traction belt around the cable reel cable storage section and guides it to the drive roller for transmission connection;

[0029] S4 uses the first transition roller and the second transition roller to make the traction belt form a circular path.

[0030] S5 starts the roller winding machine, and the traction belt is pulled by the drive roller to move the cable reel along the reel guide roller to the starting position of the concave arc section.

[0031] S6 reverses the rotation of the roller winding machine, slowly releasing the traction belt, causing the cable reel to roll down to the center of the concave arc section and come to a stable stop position.

[0032] The beneficial effects are: it provides a systematic method for cable reel introduction, including steps such as adjusting the spacing of the introduction rollers, fixing the traction belt path, and using transition rollers to form a circumferential path, to ensure that the cable reel can safely and efficiently reach the predetermined work position.

[0033] Preferably, the traction belt forms a break between the drive roller and the second transition roller, and further includes:

[0034] The traction belt is temporarily connected at the point of disconnection;

[0035] The roller winding machine is started, and the traction belt drives the cable reel to rotate around a slide rail located at the far end of the straight section, thereby lifting the cable reel using the lever principle. The beneficial effects are: this method utilizes the leverage effect between the traction belt and the slide rail to lift the cable reel, innovatively applying the principle of mechanical advantages to simplify the operation process and reduce manual labor intensity and safety risks.

[0036] Preferably, before the traction belt forms a loop path using the first and second transition rollers, the position of the first and second transition rollers is adjusted according to the diameter of the cable reel used. The beneficial effect is that adjusting the position of the transition rollers according to the different diameters of the cable reels ensures the effective adaptability of the traction belt loop path, guarantees that the equipment can achieve optimal working conditions under different circumstances, and enhances the flexibility and accuracy of operation.

[0037] In summary, the cable laying device and its guiding method, overall, have significant beneficial effects:

[0038] 1. High Efficiency and Flexibility: The device is designed to allow users to quickly and easily adjust the spacing of the cable reel guide rollers to accommodate cable reels of different diameters. This enhances the versatility and adaptability of the equipment, enabling it to efficiently handle cable reels of various specifications.

[0039] 2. Stability and Safety: Through a special design with curved and straight sections, the cable reel is smoothly guided and positioned at the designated location. This not only reduces potential equipment malfunctions and damage during operation but also ensures the safety of personnel.

[0040] 3. Mechanical Advantages and Labor Saving: The device utilizes the lever principle, employing a clever combination of traction belts and slide rails to make lifting the cable reel simple and efficient. This not only reduces the workload of operators but also improves work efficiency.

[0041] 4. Precision and Reliability: Through precise layout and adjustment, the traction belt can form an effective loop path, ensuring that the cable reel is accurately guided to the predetermined position. This not only improves work efficiency but also guarantees the quality of construction.

[0042] 5. Economy and Sustainability: The design of this device and its method fully considers cost-effectiveness and sustainability. By using simple mechanical principles and fewer components, it achieves efficient and reliable functionality, reducing manufacturing and maintenance costs.

[0043] In summary, this cable laying device and its guiding method not only improve work efficiency and safety, but also reduce costs and maintenance requirements, providing a reliable and economical solution for power construction. Attached Figure Description

[0052] Specific technical solutions

[0053] Example 1

[0054] See attached document Figure 1-7 This cable laying device for power construction includes a frame structure, 1. The lower part of the frame 1 has a laying station 2. Within the laying station 2 are two cable reel guide rollers 3 extending in the same direction and beyond the frame for the two reels of cable spool 01 to be rolled in. The two cable reel guide rollers 3 are arranged in parallel, and the distance between them is adjustable to accommodate cable reels 01 of different diameters. To facilitate maintaining the parallelism of the cable reel guide rollers 3 and adjusting their spacing, a slide rail 4 is fixedly installed inside the lower frame of the frame 1, or the structure of the lower frame itself is used as the slide rail 4, for installing and guiding the two cable reel guide rollers 3.

[0055] When adjusting the spacing of the wire reel guide rollers 3, one or two rollers can slide along the slide rail 4 to change their relative distance, thus meeting the needs of wire reels of different specifications. The parallel arrangement of the rollers facilitates the smooth introduction of the wire reel, avoiding tilting and collisions. The rollers extend to the outside of the frame, making it convenient to roll the wire reel in from the outside.

[0056] Two cable reel guide tracks 3 form a consistent downward-curving arc section 31 at the cable feeding station 2. These two concave arc sections 31 are used to form a stable support and stopping position for the cable reel 01. The smooth continuation of the concave arc section 31 is an inclined straight section 32. These straight sections 32 slope gently from far to near relative to the device frame 1, guiding the cable reel 01 to smoothly roll to the stopping position of the concave arc section 31.

[0057] This design takes into account the needs of the cable reel in different states such as insertion and parking, providing reliable reel support and guidance for cable laying operations, and improving the safety and efficiency of the operation.

[0058] A roller reel 5 is installed above the frame 1. The width of the traction belt 51 of the roller reel 5 is no greater than the width of the cable storage section of the cable reel 01. During operation, the traction belt 51 forms a loop 52 around the cable storage section. Through the traction belt 51 of the roller reel 5, the cable reel 01 can be pulled to roll along the reel guide roller 3 until it enters the stopping position of the two concave arc sections 31. Thus, the process of guiding the cable reel 01 into the unloading station 2 is completed.

[0059] Compared to traditional methods of transporting and placing wire reels using external equipment such as cranes, this rolling guidance method requires significantly less power, making it more energy-efficient and environmentally friendly. The roller winding machine 5 applies appropriate traction force to the wire reel through the traction belt 51. Utilizing the rolling of the wire reel itself and the guiding effect of the wire reel guide track 3, the wire reel can be precisely guided to the designated position. The process is smooth and controllable, avoiding the safety hazards that may be caused by rough operations such as hoisting.

[0060] This design cleverly leverages the advantages of mechanical traction and the ease of rolling, making it an efficient and environmentally friendly method of guiding the coil.

[0061] Furthermore, two slide rails 4 are provided. The slide rail located near the straight section 32 is only in contact with the spool guide roller 3 due to its own weight, meaning that they can be separated at any time. The slide rail located at the far end of the straight section 32 is hinged to the spool guide roller 3 by a sleeve connection, meaning that the spool guide roller 3 can slide along this slide rail.

[0062] This design allows the two cable reel guide tracks 3 to rotate around the slide rail at the far end of the straight section 32 as a pivot. When an upward force is applied with the free end of the cable reel guide track 3 as the force application point, the cable reel guide track 3 forms a relatively long lever arm, thus constituting a lever mechanism. Through this lever action, the force required to lift the cable reel 01 can be greatly reduced.

[0063] This design cleverly utilizes the lever principle, guiding a portion of the coil into the raceway 3 as a lever arm, thereby amplifying the applied torque and reducing the required force. Simultaneously, due to the free contact design of the proximal guide rail, no additional resistance is generated during lifting, ensuring the efficient operation of the lever mechanism. This innovative design not only reduces the burden of manual operation but also improves the controllability and safety of the entire lifting process.

[0064] Furthermore, two slide rails 4 are equipped with sliding support seats 6, which are arranged in pairs. Each support seat 6 is located on the side of its corresponding cable reel guide roller 3 away from the center of the device frame 1. When the cable reel 01 is lifted, the two support seats 6 can be pushed under the exposed part of the winding shaft 011 installed in the cable reel 01 to provide support for the winding shaft 011.

[0065] This design allows the support base 6 to be precisely moved to the support position below the take-up spool 011 after the spool is raised to a certain height.

[0066] By supporting the take-up shaft 011 with the support base 6, the load on the wire reel guide roller 3 and concave arc section 31 can be effectively reduced, avoiding deformation or damage caused by applying excessive pressure for a long time. At the same time, the support base 6 can reliably fix the position of the raised wire reel, creating a stable working environment for subsequent wire feeding operations.

[0067] This design not only improves the load-bearing capacity and service life of the device, but also increases operational safety, making it an effective and innovative technical solution.

[0068] To guide the cable reel 01 more smoothly to the cable laying station 2, the loop path 52 of the traction belt 51 is set as follows:

[0069] 1. Fix one end of the traction belt 51 on the upper part of the device frame 1, away from the straight section 32;

[0070] 2. A first transition roller 521 is set at the position of the two concave arc segments 31 of the two wire reels entering the raceway 3 and relatively close to the straight segment 32;

[0071] 3. A second transition roller 522 is installed at the lower part of the device frame 1 near the connection between the straight section 32 and the concave arc section 31;

[0072] 4. An active roller 523 is installed on the upper part of the device frame 1 near the straight section 32. The active roller 523 is connected to the power source for transmission.

[0073] In practical applications, the positions of the first transition roller 521 and the second transition roller 522 need to be adjusted adaptively according to the different diameters of the cable reels 01.

[0074] The design of the surrounding path 52 allows the traction belt 51 to form a closed traction loop in the upper and lower parts of the device frame 1, thereby smoothly pulling the cable reel 01 into the cable feeding station 2. The arrangement of the first and second transition rollers 521 and 522 enables the traction belt 51 to smoothly turn and maintain appropriate tension, avoiding slippage or breakage.

[0075] The connection between the drive roller 523 and the power source provides power to the entire traction system, enabling the cable reel 01 to be effectively pulled and its rolling speed controlled. The arrangement of the surrounding path 52 also takes into account the adaptability requirements of different reel diameters, and the traction effect can be optimized by adjusting the position of the transition roller.

[0076] This innovative design makes the most of the space in the device frame 1, with a reasonable and compact layout, which not only achieves stable and efficient coil guidance, but also has a certain degree of adjustability.

[0077] The following describes the complete process of cable reel 01 being guided to cable laying station 2 via the traction belt 51 along a circular path:

[0078] 1. Initial state (refer to) Figure 1 The two reels of cable reel 01 are located at the starting point of the straight section 32, and the traction belt 51 is located below the cable reel storage section.

[0079] 2. Traction start (refer to) Figure 2 The traction belt 51 is connected to the drive roller 523 after it wraps around the cable reel storage section. The roller winding machine 5 starts and tightens the traction belt 51, causing the cable reel 01 to slowly advance along the reel guide roller 3.

[0080] 3. Transition roller guidance (refer to) Figure 3 When the cable reel 01 travels between the first and second transition rollers 521 / 522, the traction belt 51 is fully tightened, and at this time the reel has just completed the straight section 32.

[0081] 4. Roll-off line placement (refer to) Figure 3 The cable reel 01 stops at the starting position of the concave arc section 31, and has a tendency to roll towards the center of the concave arc. The roller winding machine 5 reverses and slowly releases the traction belt 51, causing the reel to slowly fall into the unwinding station 2.

[0082] 5. Unloading the traction belt: Finally, the traction belt 51 is unloaded from the drive roller 523, completing the entire process of the cable reel 01 entering the cable feeding station 2.

[0083] This design, through the carefully arranged traction belt 51 surrounding the path and the cooperation of multiple key components such as the drive roller 523 and transition rollers 521 / 522, achieves the goal of smoothly guiding and accurately positioning the cable reel 01. It has the advantages of simple operation and energy saving. The entire process is highly controllable and safe.

[0084] Example 2

[0085] Reference Figure 6Based on the design of Embodiment 1, the traction belt 51 is also fixedly connected to the other end of the drive roller 523, so that the traction belt 51 forms a break between the drive roller 523 and the second transition roller 522. This break can be temporarily joined by a detachable connector such as a hinge.

[0086] The advantage of this design is that when it is necessary to elevate the cable reel 01, a movable connector can be installed at the break point to temporarily connect the traction belt 51 to the free end of the straight section 32. Then, by winding the traction belt 51 with the drive roller 523, the cable reel can be lifted and guided into the roller track 3 using the lever principle, thereby completing the elevation operation of the cable reel 01.

[0087] This innovative design endows the traction belt 51 with dual functions: firstly, the guiding function as in Example 1; and secondly, by means of the movable connection at the disconnection point, it can be temporarily converted into a power transmission belt for lifting the reel and guiding it into the roller 3. This design is simple and ingenious, avoiding the need for a new lifting mechanism, making full use of the existing traction system, achieving integrated operation of multiple functions, and significantly reducing system complexity and cost.

[0088] Meanwhile, the detachable connector design makes it very convenient to assemble and disassemble the movable connection, simplifying the operation and avoiding the inconvenience that may be caused by fixed connections. This design not only gives full play to the primary function of the traction belt, but also endows it with additional lifting capacity.

[0089] Example 3

[0090] Based on the two embodiments above, the method for guiding the cable reel into the workstation is summarized as follows:

[0091] This method aims to guide the cable reel smoothly and efficiently to the laying position, ensuring a controllable, safe, and environmentally friendly process. It is suitable for various power construction sites and offers advantages such as energy saving, environmental friendliness, and ease of operation.

[0092] Step 1: Preparation

[0093] 1) Check whether the device frame, spool guide roller, slide rail and other components are intact;

[0094] 2) Adjust the spacing of the cable reel guide rollers to match the diameter of the cable reel used;

[0095] 3) Confirm that the roller winding machine is correctly connected to the power source;

[0096] 4) Move the two reels of the cable spool to the starting position at the far end of the straight section.

[0097] Step 2: Deployment of the traction belt

[0098] 1) Fix one end of the traction belt to the far end of the upper part of the device frame;

[0099] 2) The section for receiving the coil is surrounded and guided to the drive roller for transmission connection;

[0100] 3) The first and second transition rollers are used to turn the traction belt and form a circular path;

[0101] 4) Adjust the position of the transition rollers if necessary to ensure that the traction belt can properly wrap around the reel.

[0102] Step 3: Traction and Injection

[0103] 1) Start the roller winding machine, and the drive roller begins to pull the belt.

[0104] 2) The traction belt tightens, and the cable reel is slowly guided forward along the roller track;

[0105] 3) When the spool passes the second transition roller, the traction belt will be fully tightened;

[0106] 4) Continue pulling until the reel stops at the starting position of the concave arc segment.

[0107] Step 4: Positioning and layout station

[0108] 1) The roller winding machine reverses its direction and slowly releases the traction belt;

[0109] 2) The coil rolls down to the center of the concave arc segment, where it comes to a stable resting position;

[0110] 3) Remove the traction belt from the drive roller to complete the introduction process.

[0111] Step 5: Set up the cable reel (if needed)

[0112] 1) Temporarily connect the traction belt at the break between the drive roller and the second transition roller;

[0113] 2) The active roller winds up the traction belt and uses the lever principle to lift the reel and guide it into the roller track;

[0114] 3) Move the support base below the winding shaft to provide support for the coil.

[0115] This method eliminates the need for large hoisting equipment, automatically guiding the cable reel to the workstation via a simple traction action. The process is safe, controllable, environmentally friendly, energy-saving, and consumes little power. It also incorporates a lever lifting function for raising the cable reel. The entire solution is rationally designed, easy to operate, safe, and efficient.
