Description

Technical Field

[0001] The present invention relates to the field of electric power construction equipment, in particular to a new type of cable pay-off device, which aims to solve the problems of cumbersome installation and disassembly of cable reels, potential safety hazards in the guiding method, high energy consumption, poor stability and limited mobility in the prior art. Through innovative design, the present invention aims to provide a cable pay-off device that simplifies the installation and disassembly process, improves load-bearing stability, enhances mobility and reduces energy consumption, so as to improve the efficiency, safety and practicality of electric power construction. Background Art

[0002] In power construction, cable laying is a key link that has a significant impact on construction efficiency and safety. However, traditional cable laying devices have a series of problems that not only affect the convenience of construction, but also have a negative impact on operation efficiency and safety.

[0003] First, the center shaft design of the traditional device requires cumbersome installation and removal. When installing the cable drum, the staff must precisely insert and fix the center shaft to the drum, which is a complex, time-consuming and labor-intensive process. The choice of bearing size that the center shaft relies on further limits the scope of application of the device, resulting in limited flexibility when dealing with different size drums and relatively high maintenance costs.

[0004] Secondly, for cable reels with larger diameters, the traditional center shaft design cannot provide sufficient load-bearing capacity and stability. Due to the limitation of bearing size, when the diameter of the cable reel increases, its load-bearing capacity may not meet the requirements, and stability is difficult to ensure, which increases safety risks and increases maintenance frequency and costs.

[0005] Finally, the traditional solution only relies on the central axis and base support during the wire drum pay-off process, lacking effective auxiliary support and guidance mechanisms. This causes the wire drum to easily move and shake when rotating to pay off the wire, thus affecting the stable rotation of the wire drum, limiting the efficiency of the pay-off operation and reducing the safety of the operation.

[0006] Therefore, in view of the shortcomings of the existing technology, there is an urgent need to develop an improved cable pay-off device that can simplify the installation and disassembly process of the cable reel, improve the applicability and stability of the device, reduce maintenance work, and improve the overall efficiency and safety of the pay-off operation through optimized design. Summary of the invention

[0007] In view of this, the present invention provides an auxiliary tooling for cable reel laying-out construction, which significantly improves the efficiency, stability and safety of the laying-out construction, while reducing the operating difficulty and labor intensity, through the design of an internal expansion centering chuck, a device frame, a support seat and an installation mechanism.

[0008] The technical solution of the embodiment of the present invention is implemented as follows: an auxiliary tool for cable reel laying construction, comprising:

[0009] The internal expansion centering chuck is used to replace the original reel installed in the center of the cable reel, and the internal expansion centering chuck includes:

[0010] An expansion mandrel with adjustable length and a conical head at one end for insertion and wedging into the center hole of the reel for fixation;

[0011] The receiving ring is a hollow ring structure with a rolling device on the outer circumference;

[0016] Preferably, the support base is equipped with a sensor and can automatically adjust the height through an electric or hydraulic system. The beneficial effect is that the support base equipped with a sensor can monitor the status of the cable drum in real time, such as weight, position, etc., so as to make timely adjustments. The function of automatically adjusting the height of the electric or hydraulic system allows the support base to adapt to cable drums of different sizes, thereby improving the compatibility of the tooling.

[0017] Preferably, a chuck installation mechanism is provided at the top of the column of the device frame, including a chuck bracket that can move up and down and a rotation drive device. The beneficial effect is that the design of the installation mechanism makes the installation and replacement of the internal expansion centering chuck simpler and more efficient, reduces the difficulty and labor intensity of manual operation, and improves work efficiency.

[0018] Preferably, the installation mechanism has a high-precision positioning function and can realize automatic operation. The beneficial effect is that the high-precision positioning function ensures the accuracy and stability of the installation of the internal expansion centering chuck, while the automatic operation further reduces manual intervention and improves the reliability and efficiency of the operation.

[0019] As a preferred embodiment, an ergonomic operation interface, an emergency stop button, an overload protection system, a warning sign, and a lighting safety and convenience facility are provided. The beneficial effect is that the setting of the ergonomic operation interface, the emergency stop button, the overload protection system, the warning sign, the lighting and other safety and convenience facilities provides a safer and more comfortable working environment for the operator and reduces the operation risk.

[0020] Preferably, the expansion mandrel of the internal expansion centering chuck is detachably connected to the receiving ring, so as to be easily replaced separately.

[0033] Refer to all attached Figure 1-3 .

[0034] Embodiment 1 describes an auxiliary tool for cable reel laying construction. The tool comprises an internal expansion centering chuck 1 installed at the center of the cable reel to replace the reel. The internal expansion centering chuck 1 comprises an expansion mandrel 11 located in the center and a receiving ring 12 on the outer ring.

[0035] The expansion mandrel 11 is designed to be retractable and adjustable in length, and a conical head is provided at the end of the shaft. During installation, the expansion mandrel 11 is first inserted into the center hole of the cable drum, and then the mandrel is extended by rotating the top, and the conical head will wedge into the wall of the center hole of the drum, thereby achieving a fixed centering effect on the drum.

[0036] The receiving ring 12 is a hollow ring structure, and a roller or a ball wheel is arranged on the periphery so as to roll and rotate on the supporting seat 5.

[0037] A device frame 2 of a frame structure is provided, and a wire-laying station 3 is provided in the lower area inside the device frame 2 for accommodating and positioning the cable reel for wire-laying operation.

[0038] In the area of ​​the wire-laying station 3, two support seats 5 are arranged in pairs. The support seats 5 are designed with a height-adjustable structure, which can adapt to cable reels of different diameters and adjust the wire-laying height as needed.

[0039] The support surface of the support seat 5 is provided with a V-shaped groove or other concave shape to cooperate with the rolling of the receiving ring 12 on the inner expansion centering chuck 1. The support seat 5 itself can also be provided with a moving mechanism such as a roller or a universal joint so that it can move freely to a suitable position.

[0040] During the wire laying operation, first install the inner expansion centering chuck 1 into the center holes at both ends of the cable reel to be laid. Then, lift the reel with the chuck 1 to a certain height, and then push the two support seats 5 forward respectively, so that the receiving ring 12 can be seated on the rolling guide rail of the support seat 5, so as to reliably lift the reel off the ground.

[0041] Through the design of the support seat 5, in combination with the receiving ring 12 of the inner expansion centering chuck 1, during the wire laying process, the cable reel can rotate around the ring smoothly to avoid shaking and displacement, thereby ensuring the stability and safety of the wire laying operation. At the same time, the height adjustment of the support seat 5 also enables the wire laying height to be optimized according to actual needs.

[0042] Since the internal expansion centering chuck 1 adopts the design of expansion mandrel 11 and receiving ring 12, its overall weight will be greater than the original simple winding shaft structure. The purpose of doing so is to increase the support area, so that the wire drum is more stable and reliable when the wire is released and rotated.

[0043] In order to facilitate the installation and replacement of the heavier internal expansion centering chuck 1, a chuck installation mechanism 4 is provided on the top of the column of the device frame 2.

[0044] The installation mechanism 4 includes a chuck bracket 41 that can move up and down and a rotation drive device 42. When a new cable drum needs to be replaced, the operator first moves the inner expansion centering chuck 1 on the old drum to the position of the chuck installation mechanism 4, and then controls the chuck bracket to descend so that the inner expansion centering chuck 1 is vertically clamped into the bracket.

[0045] Next, the chuck bracket rises to a certain height, and then the rotary drive device rotates the entire bracket together with the inner expansion centering chuck 1 by 180 degrees, so that the inner expansion centering chuck 1 is turned from a vertical state to a horizontal state. Finally, the operator can easily install the inner expansion centering chuck 1 in a horizontal state into the center hole of the new wire drum.

[0046] Through the design of up and down lifting and rotating actions, even if the internal expansion centering chuck 1 itself is heavy, the operator can easily and efficiently complete its installation and replacement, avoiding tedious and laborious manual operations and improving work efficiency.

[0047] The design of the chuck mounting mechanism 4, combined with the design of the support seat 5, greatly enhances the practicality and operability of this set of cable reel laying auxiliary tooling.

[0048] Other auxiliary facilities: In order to prevent the wire drum from moving horizontally during the wire release process, a block or limit device can be provided on the side of the device frame 2; in order to facilitate the operator to move around and check, an operating platform can be provided around the wire release station 3. In addition, auxiliary facilities such as lighting, power sockets, control buttons, etc. can be provided.

[0049] Through the above-mentioned extended design, the cable reel payout auxiliary tooling can not only bear and support the reel, but also the installation and replacement of the reel are more convenient and efficient, and the overall tooling structure is more reasonable and reliable.

[0050] Embodiment 2 expands and optimizes the technical solution of Embodiment 1, and specifically includes:

[0051] 1. Optimized design of the internal expansion centering chuck 1:

[0052] The expansion mandrel 11 is made of high-strength lightweight alloy material to ensure strength while reducing overall weight.

The integrated bearing structure reduces friction when contacting with the support seat 5 and improves rotation smoothness.

[0053] 2. Improvements of the device frame 2 and the wire-laying station 3:

[0054] The device frame 2 adopts modular design and can be assembled flexibly according to the size of the construction site. The wire laying station 3 is equipped with an automatic leveling system to ensure that the wire reel is placed horizontally. Anti-skid pads or rubber pads are added to increase friction and prevent sliding.

[0055] 3. Intelligent transformation of support seat 5:

[0056] The support base 5 is equipped with a sensor to monitor the status of the wire reel in real time. The height can be automatically adjusted through an electric or hydraulic system to adapt to wire reels of different sizes.

[0057] 4. Innovation of centering chuck installation mechanism 4:

[0058] The design has high-precision positioning function to ensure accurate installation. Automated design such as remote control or programming control can be used to reduce the difficulty of manual operation.

[0059] 5. Enhanced safety and convenience:

[0060] It is equipped with ergonomic operation interface, emergency stop button, overload protection system, warning signs and lighting, etc.

[0061] 6. Improved mobility and compatibility:

[0062] The bottom is equipped with wheels for easy on-site movement and redeployment. Compatible with different specifications of reels and chuck types to improve versatility.

[0063] Through the above comprehensive improvements and innovations, the efficiency, safety and ease of use of the cable reel payout auxiliary tooling can be significantly improved to meet the needs of various complex working conditions.

[0064] Example 3: Intelligent cable reel laying auxiliary tooling

[0065] On the basis of Example 1 and Example 2, Example 3 further introduces intelligent technology into the cable reel pay-out auxiliary tooling to achieve more efficient, safe and automated pay-out operations.

[0066] Intelligent control system:

[0067] The entire auxiliary tooling is equipped with an intelligent control system that can monitor the reel's pay-off status, speed, tension and other parameters in real time, and automatically adjust according to preset parameters or real-time operating requirements.

[0068] Adaptive pay-off tension control:

[0069] The tension sensor installed on the cable drum monitors the cable tension in real time and links with the control system. When the tension exceeds or falls below the set value, the control system can automatically adjust the pay-off speed or apply the brake to ensure stable cable tension during the pay-off process.

[0070] Automatic reel changing system:

[0071] An automatic reel replacement mechanism is added, which can automatically unload the old reel and load the new reel without manual intervention. The system includes an automatic lifting platform, a reel centering device, and a chuck automatic locking and unlocking mechanism. When the old reel is paid off, the system can automatically move the old reel aside, then move the new reel to the pay-off station, and automatically install and lock the chuck.

[0072] Intelligent identification and positioning system:

[0073] The image recognition technology is introduced to automatically identify the logo and parameter information (such as wire diameter, material, length, etc.) on the wire reel through the camera installed on the device frame. Based on this information, the control system can automatically adjust the wire laying parameters to ensure efficient and safe operation.

[0074] Remote monitoring and operation:

[0075] Combined with the Internet of Things technology, the operating status of auxiliary tooling, operation data and other information are uploaded to the cloud platform in real time. Operators can remotely monitor the wire laying operation through mobile phones or computers and perform remote operations when necessary. In addition, through big data analysis, wire laying operations can be optimized to improve operation efficiency and quality.

[0076] Through the intelligent transformation of Example 3, the cable reel laying auxiliary tooling can not only achieve more efficient and automated operations, but also improve the safety and reliability of the operations. At the same time, combined with the Internet of Things and big data technology, it can also achieve comprehensive monitoring and optimization of the laying operation, bringing greater economic benefits and competitiveness to the enterprise.
