Description
Technical Field
[0001] This utility model relates to the field of power engineering technology, specifically to a cable traction device for power construction. Background Technology
[0002] With the continuous advancement of smart grid construction and the accelerated pace of urban and rural power distribution network upgrading and transformation, the demand for laying medium and low voltage power cables in power construction is increasing. Especially in scenarios such as urban road reconstruction, residential community power distribution, industrial park wiring and emergency repair, cable laying and pulling operations are frequent, and the construction environment is complex and changeable, which puts forward higher requirements for the mobility, adaptability and work efficiency of construction equipment.
[0003] In traditional cable laying operations, traction equipment is often used to lay cables. It mainly consists of a traction vehicle, a traction frame, and a cable reel. Its core function is to lay cables by mechanical traction. Compared with traditional manual cable laying, traction equipment can significantly improve work efficiency.
[0004] However, most existing tractor vehicles only have a single traction function and lack a coordinated control mechanism with the cable laying process, making it difficult to maintain a stable cable tension during installation. If the tension is too low, the cable is prone to slack and dragging on the ground, causing wear or contamination of the outer sheath; if the tension is too high, the cable is prone to being overstretched, causing insulation deformation, conductor damage, and even the risk of breakage, seriously affecting the laying quality and subsequent operational safety. Utility Model Content
[0005] This utility model provides a cable traction device for power construction. By setting up track wheels, cross plates and springs, it can maintain the stability of cable laying tension, improve the laying quality and safety of cables, and solve the problems mentioned in the background art, such as the lack of coordinated control of traditional traction vehicles, unstable tension, easy cable damage, and the impact on cable laying quality and safety.
[0006] This utility model provides the following technical solution: A cable traction device for power construction includes a traction vehicle and a traction frame rotatably mounted on the traction vehicle. A cable reel is rotatably mounted on the traction frame. The device also includes a track wheel on the traction frame. A cooperating frame is fixedly connected to the traction frame. A cross plate is connected to the cooperating frame via an elastic element. The track wheel is connected to the bottom of the cross plate via a movable element. An adjusting element is provided on the cooperating frame and is used to adjust the elastic coefficient of the elastic element. Scale lines for cooperating with the adjusting element are fixedly connected to both sides of the cooperating frame.
[0007] As a preferred embodiment of this utility model, the elastic element includes springs disposed on both sides of the coordinating frame, and buckles are fixedly connected to both the coordinating frame and the horizontal plate, with the springs snapped between the two buckles.
[0008] As a preferred technical solution of this utility model, the moving part includes a guide groove opened at the bottom of the horizontal plate, a guide block slidably connected in the guide groove, a wheel frame fixedly connected to the guide block, a track wheel rotatably connected to the wheel frame, and the cable on the reel passes through the wheel frame and rests in the groove of the track wheel.
[0009] As a preferred embodiment of this utility model, the adjusting component includes an electric push rod fixedly installed on the coordinating frame, the output end of the electric push rod is fixedly connected to a pressure plate, and the horizontal plate abuts against the bottom surface of the pressure plate by the elastic force of a spring.
[0010] As a preferred embodiment of this utility model, a support rod is fixedly connected to one side of the horizontal plate, and a guide ring is fixedly connected to the end of the support rod. A roller is rotatably installed inside the guide ring, and the cable on the reel is inserted into the guide ring.
[0011] As a preferred technical solution of this utility model, the collaborative frame has sliding grooves on both sides, and the horizontal plate has sliders fixedly connected to both sides, with the sliders slidably connected in the sliding grooves.
[0012] Compared with the prior art, this utility model provides a cable pulling device for power construction, which has the following advantages: 1.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0019] Reference Figures 1-4A cable traction device for power construction includes a tractor 1 and a traction frame 2 rotatably mounted on the tractor 1. The tractor 1 is a Hangzhou Lishi semi-trailer tractor 1 series. A cable reel 3 is rotatably mounted on the traction frame 2. The device also includes: a track wheel 4 mounted on the traction frame 2 for transmitting the cable on the cable reel 3; a cooperating frame 5 fixedly connected to the traction frame 2; a cross plate 6 connected to the cooperating frame 5 via an elastic element; grooves 51 are provided on both sides of the cooperating frame 5; sliders 52 are fixedly connected to both sides of the cross plate 6, and the sliders 52 are slidably connected within the grooves 51 to improve the stability of the cross plate 6; and the track wheel 4 is connected to the cross plate 6 via a moving part. The bottom of the horizontal plate 6 includes a guide groove 82 at the bottom of the horizontal plate 6, a guide block 8 slidably connected in the guide groove 82, a wheel frame 81 fixedly connected to the guide block 8, and a track wheel 4 rotatably connected to the wheel frame 81. The cable on the reel 3 passes through the wheel frame 81 and rests in the groove of the track wheel 4. During the cable feeding process, the guide block 8 can drive the track wheel 4 to slide along the guide groove 82, which can adapt to the cable feeding trajectory on the reel 3 and ensure that the cable is stably transmitted along the track wheel 4. An adjustment component is provided on the cooperating frame 5, and the adjustment component is used to adjust the elastic coefficient of the elastic component. Scale lines 7 for cooperating with the adjustment component are fixedly connected to both sides of the cooperating frame 5.
[0020] Of course, in other embodiments, the elastic element includes springs 62 located on both sides of the coordinating frame 5. Buckles 61 are fixedly connected to both the coordinating frame 5 and the cross plate 6. The springs 62 are snapped between the two buckles 61. This connection method facilitates the subsequent replacement of the springs 62.
[0021] Specifically, during use, when the tension on the cable increases, it compresses the track wheel 4 and the cross plate 6 to move, causing the spring 62 to stretch and absorb part of the tension. When the tension on the cable decreases, the restoring force of the spring 62 pulls the cross plate 6 and the track wheel 4 to move in the opposite direction and compensate for the tension. This enables the cable to adapt to its own tension, allowing the cable to maintain a stable laying tension during the laying process.
[0022] The adjusting component includes an electric actuator 71 fixedly mounted on the coordinating frame 5. The model can be Jiechang JC35FA2 or Thomson Electrak-XD. The output end of the electric actuator 71 is fixedly connected to a pressure plate 72. The horizontal plate 6 abuts against the bottom surface of the pressure plate 72 through the elastic force of the spring 62. Here, the horizontal plate 6 and the pressure plate 72 only contact each other through the elastic force, and the two are not fixedly connected.
[0023] Specifically, during use, by activating the electric actuator 71, the pressure plate 72 can be driven to extend and retract, and the horizontal plate 6 can be driven to move up and down according to the scale line 7. This changes the extension and retraction length of the spring 62, thereby facilitating the rapid adjustment of the spring force coefficient of the spring 62 to linearly adjust the tension it provides, so as to meet the laying requirements of cables of different specifications and improve the applicability of the equipment.
[0024] A support rod 9 is fixedly connected to one side of the horizontal plate 6. A guide ring 91 is fixedly connected to the end of the support rod 9. A roller 92 is rotatably installed inside the guide ring 91. The cable on the winding reel 3 is inserted into the guide ring 91.
[0025] Specifically, the support rod 9, guide ring 91 and roller 92 can support and guide the cable, which helps to improve the cable laying stability and tension stability.
[0026] Components not described in detail in this article are existing technologies and will not be elaborated upon here.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
