Description

Technical Field

[0001] This utility model relates to the field of power facility technology, specifically to a cable-laying frame for power facilities. Background Technology

[0002] Cable laying frames are crucial equipment in power engineering construction, primarily used to support and release cables, ensuring smooth and stable cable laying and preventing cable damage or construction interruptions. With the continuous expansion of power engineering projects and increasingly stringent construction requirements, the performance and functional demands of cable laying frames are also constantly increasing. However, existing cable laying frame technologies still have many shortcomings and cannot fully meet the needs of modern power cable laying.

[0003] Existing wire-laying frames generally suffer from poor mobility. This is mainly due to their large size, making them inconvenient to move and transport. On construction sites, it usually requires several or even a dozen workers to work together to roll the winding wheel with the power cable wrapped around it to the wire-laying side and then place the winding wheel on the placement beam of the wire-laying frame. This makes it difficult for the wire-laying frame to adapt to complex construction environments. Utility Model Content

[0004] In view of the problems and shortcomings of the existing technology, this utility model provides a wire laying frame for power facilities.

[0005] The technical solution of this utility model is as follows:

[0006] A cable-laying frame for power facilities includes: a base frame, two columns connected to the base frame and spaced apart, a connecting crossbeam connecting the middle of the two columns laterally, a placement crossbeam parallel to the connecting crossbeam and slidingly engaging with the two columns, and a lifting mechanism fixed to the connecting crossbeam and driving the placement crossbeam to move up and down.

[0007] The base frame is connected to a fixing plate at the bottom and equipped with a level at the top.

[0008] The bottom of the fixed plate is connected to casters and feet. The casters are located in the middle of the fixed part, and at least two casters are arranged in an array along its width. The height of the feet is adjustable, and at least two feet are provided.

[0009] Preferably, the level is located in the middle of the top surface of the base frame.

[0010] Preferably, two feet are provided, which are arranged colinearly with the caster and are respectively located on the outside of the caster along the width direction of the base frame.

[0011] Furthermore, to improve the stability of the base frame, three feet can be installed, arranged in a triangle around the outer perimeter of the casters.

[0012] Preferably, the caster is threaded to the fixed plate in the middle, extends upwards out of the base frame at the top, and is connected to an adjustment handle at the end.

[0013] Preferably, the base frame is a frame structure welded from structural steel. The lifting mechanism uses a hydraulic push rod, with its bottom fixed end fixedly connected to the connecting crossbeam and its upper non-free end connected to the placement crossbeam. The top surface of the placement crossbeam has a circular arc groove in the middle for engaging with the rotating shafts at both ends of the winding reel.

[0014] The beneficial effects of this utility model are:

[0015] 1) Adaptability to complex construction environments. This solution significantly improves the mobility and stability of the cable-laying frame by installing casters and height-adjustable feet at the bottom of the base frame. The casters facilitate rapid movement of the equipment on the construction site, while the height-adjustable feet ensure horizontal fixation of the equipment under different terrain conditions, guaranteeing stable operation of the cable-laying frame in complex construction environments. Furthermore, the installation of a level further ensures the levelness of the base frame, avoiding problems such as equipment tilting or unsmooth cable laying caused by uneven ground.

[0016] 2) Convenient operation and reduced labor intensity. This solution uses a hydraulic push rod as the lifting mechanism to drive the placement frame to move up and down, easily lifting the winding wheel to a suitable height without manual handling or the use of other lifting equipment. This not only significantly reduces the labor intensity of workers but also improves construction efficiency, making it particularly suitable for the installation and disassembly of large cable winding wheels.

[0017] 3) Stable structure and strong load-bearing capacity. The base frame adopts a frame structure welded from structural steel, which has high strength and stability and can withstand the weight of large cable winding reels. The arc groove set in the middle of the top surface of the crossbeam cooperates with the rotating shafts at both ends of the winding reel, further enhancing the stability of the winding reel on the pay-off frame and preventing the winding reel from shaking or deviating during cable release.

[0018] 4) High versatility and wide applicability. This solution, through modular design, can adapt to cable winding reels of different specifications and weights. The number and arrangement of casters and feet can be flexibly adjusted according to actual needs. For example, two feet can be arranged coaxially with the casters, or three feet can be arranged in a triangle, further improving the stability and adaptability of the equipment. In addition, the lifting height of the hydraulic push rod is adjustable, meeting the cable laying requirements of different heights.

[0019] 5) Improved construction efficiency and reduced costs. This solution, through optimized structural and functional design, reduces reliance on manpower and auxiliary equipment during construction, significantly improving cable laying efficiency. Simultaneously, lower equipment manufacturing and maintenance costs effectively reduce overall construction costs, demonstrating high economic efficiency and practicality.

[0020] 6) High safety and reduced construction risks. This solution ensures the stability and safety of the equipment during construction through the coordinated action of a level, height-adjustable feet, and hydraulic push rods, avoiding construction accidents caused by equipment tilting or unstable winding wheels, and protecting the safety of construction personnel.

[0025] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0026] Example

[0027] See Figure 1 A cable-laying frame for power facilities includes: a base frame 1, two columns 2 connected to the base frame 1 and spaced apart, a connecting crossbeam connecting the middle of the two columns 2 laterally, a placement crossbeam 3 parallel to the connecting crossbeam and slidingly engaged with the two columns 2, and a lifting mechanism 4 fixed to the connecting crossbeam and driving the placement crossbeam to move up and down.

[0028] See Figure 2 The bottom of the base frame 1 is connected to the fixing plate 9, and the top is equipped with a level 8.

[0029] The bottom of the fixed plate 9 is connected to the casters 6 and the feet 7. The casters 6 are located in the middle of the fixed part, and at least two casters 6 are arranged in an array along its width direction. The height of the feet 7 is adjustable, and at least two feet are provided.

[0030] In use, the height of the feet 7 can be adjusted so that it is lower than the height of the casters 6. Then, the casters 6 drive the cable-laying frame to move onto the winding wheel 10, which is wrapped with power cables. The winding wheel 10 is then moved onto the cable-laying frame manually or by other means, so that its axle aligns with the arc groove of the horizontal support 3. Next, the height of the feet 7 is adjusted so that the remaining bottom surfaces are in contact, and this adjustment continues until the casters 6 are detached from the bottom surface and fixed. All feet 7 are adjusted to be at approximately the same height, and the level 8 is observed until the bubble in the level 8 is centered. Then, the lifting mechanism 4 is activated. The lifting mechanism 4 drives the horizontal support 3, causing the winding wheel 10 to move upwards, ensuring a gap between the winding wheel 10 and the ground for smooth rotation.

[0031] The level 8 is located in the middle of the top surface of the base frame 1. The level 8 measures the levelness of the cable laying frame, thereby avoiding problems such as equipment tilting or uneven cable laying caused by uneven ground.

[0032] According to a specific embodiment, two feet 7 are provided, which are arranged colinearly with the caster 6 and are respectively located on the outside of the caster 6 along the width direction of the base frame 1.

[0033] To improve the stability of the base frame 1, three feet 7 can be installed, arranged in a triangle around the outer perimeter of the casters 6.

[0034] The middle part of the caster 6 is threaded to the fixed plate 9, the top of which extends upward out of the base frame 1, and an adjustment handle is connected to the end.

[0035] See Figure 1 and Figure 2 In one specific embodiment, the base frame 1 is a frame structure welded from structural steel. Specifically, it can be welded from angle steel or channel steel. A reinforcing rod 5 connects the base frame to the uprights. The lifting mechanism 4 uses a hydraulic push rod, with its bottom fixed end fixedly connected to the connecting crossbeam and its upper non-free end connected to the placement crossbeam 3. The top surface of the placement crossbeam 3 has a circular arc groove in the middle for engaging with the rotating shafts at both ends of the winding wheel 10.
