Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, specifically to a cable laying device for power engineering construction. Background Technology

[0002] Power engineering is a systematic project involving power generation, transmission, distribution, and consumption. Its aim is to achieve the safe, stable, and efficient transmission and distribution of electrical energy to meet the electricity needs of social production and daily life. Cable laying is a crucial construction step in power engineering. The main purposes of cable laying are: first, to ensure the reliability and safety of power transmission. By rationally planning cable routes and laying methods, interference and damage from external factors can be reduced, such as avoiding mechanical damage, chemical corrosion, and the influence of underground currents, thereby lowering the cable failure rate. Second, to facilitate operation, maintenance, and troubleshooting. Scientific cable laying allows for a clear cable layout, facilitating regular inspections of cable conditions by construction personnel, enabling timely detection and handling of problems, rapid fault location, and shorter power outage times.

[0003] CN220022122U discloses a power cable laying device, comprising a main body, a motor box fixedly connected inside the main body, a servo motor fixedly connected inside the motor box, a transmission rod splinedly connected to the output end of the servo motor, a connecting shaft fixedly connected to one end of the transmission rod, a telescopic column fixedly connected to the inner side wall of the main body, a spring sleeved on the surface of the telescopic column, a circular baffle fixedly connected to one end of the telescopic column, a laying plate fixedly connected to the bottom end of the main body, a transmission roller rotatably connected inside the laying plate, and a transmission slide plate fixedly connected to one end of the laying plate. This power cable laying device, through the arrangement of the servo motor and the connecting shaft, can effectively improve the laying speed when the device is operated by personnel, thereby improving the construction efficiency of cable laying and reducing working time.

[0004] The problem with the aforementioned power cable laying device is that when the diameter of the cable roll gradually decreases during laying, it can easily lead to inconsistent cable release speeds, resulting in unstable tension, which can easily damage the cable or cause it to pile up. At the same time, the connecting shaft and the circular baffle can easily cause the cable roll to shake when rotating rapidly, affecting the stability of the laying and even causing it to fall off. Utility Model Content

[0005] This utility model proposes a cable laying device for power engineering construction, which solves the problems in the prior art that cables cannot be laid in a stable and orderly manner, and that cables are prone to loosening and falling off under the influence of rapid rotation of the connecting shaft.

[0006] The technical solution of this utility model is as follows: A cable laying device for power engineering construction includes a transport component, the transport component includes a transport seat and a disassembly plate snapped onto the side of the transport seat, the transport component also includes a cable winding reel rotatably connected in the middle of the transport seat and the disassembly plate for storing the cable to be laid, a limiting component set on the upper and lower sides of the inner side of the transport seat to limit the cable to be laid on the outer side of the cable winding reel to prevent it from falling off, and a conveying component set on the top of the inner side of the transport seat to pull the cable and output it for laying.

[0007] Preferably, the limiting component includes a forward and reverse motor, which is fixedly installed on the top of the transport seat. A threaded rod is fixedly connected to the output end of the forward and reverse motor, and the threaded rod is rotatably connected to a slot in the side wall of the transport seat through the forward and reverse motor.

[0008] Preferably, the limiting component further includes a slide block, which is disposed inside the transport seat above the cable winding reel, and the slide block is threadedly connected to the outside of the threaded rod.

[0009] Preferably, the limiting assembly further includes a spring connecting plate, the top of which is fixedly connected to the slide block; the limiting assembly further includes a first support bracket, which is symmetrically fixedly connected to the bottom of the spring connecting plate; and the limiting assembly further includes a first roller, which is rotatably connected to the middle of the first support bracket.

[0010] Preferably, the limiting component further includes a second support frame, which is obliquely disposed at the bottom of the inner side of the transport seat. A spring ring is provided at the bottom of the second support frame. One end of the spring ring is fixedly connected to the second support frame, and the other end of the spring ring is fixedly connected to a slot at the bottom of the inner side of the transport seat. The limiting component further includes a second roller, which is rotatably connected to the top of the second support frame.

[0011] Preferably, the conveying assembly includes two sets of rotating shafts rotatably connected to the bottom of the inner side of the transport seat. The conveying assembly also includes a toothed disc fixedly connected to the top of each of the rotating shafts. The two sets of toothed discs are in contact and are meshed and rotatably connected. The conveying assembly also includes an anti-slip conical roller fixedly connected to the outer side of each of the rotating shafts.

[0012] Preferably, the conveying assembly further includes a stepper motor, which is fixedly installed inside the transport seat, and the output end of the stepper motor is fixedly connected to one of the sets of rotating shafts.

[0013] Preferably, the transport assembly further includes casters rotatably connected to the bottom of the transport seat, and the transport assembly also includes handles symmetrically fixed to the sides of the transport seat.

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

[0015] 1. Dynamic adaptive limit structure

[0016] Innovation points:

[0017] The design employs a bidirectional elastic limit system with a first roller and a second roller. The height of the slide is adjusted by a threaded rod driven by a forward and reverse motor. Combined with the elastic pressure of the spring connecting plate and the spring ring, it adapts to changes in the cable reel diameter in real time.

[0018] Disadvantages compared to others:

[0019] Compared to the patented method that relies on a fixed telescopic column and spring for passive limiting, which cannot dynamically adjust the pressure, the cable is prone to loosening when the diameter decreases.

[0020] 2. Anti-slip conical rollers and meshing transmission

[0021] Innovation points:

[0022] The conveying assembly adopts a design with anti-slip conical rollers and meshing toothed discs. Two sets of rollers rotating in opposite directions are driven by a stepper motor to form a stable clamping force and prevent the cable from slipping.

[0023] Disadvantages compared to others:

[0024] In contrast, the patented transmission roller has a planar structure, which results in insufficient friction and can easily cause the cable to slip off during high-speed laying.

[0025] 3. Multi-point elastic limiting to prevent slippage

[0026] Innovation points:

[0027] The limiting assembly forms a surrounding limit on the cable reel by means of the first roller arranged obliquely upwards and the second roller downwards, preventing the cable from shaking and falling off during rapid rotation or movement.

[0028] Disadvantages compared to others:

[0029] The comparison patent uses only two circular baffles for fixing, which makes the cable prone to coming off from the top and bottom due to centrifugal force or vibration.

[0030] 4. Tension self-balancing mechanism

[0031] Innovation points:

[0032] The dual elastic structure of the spring connecting plate and the spring coil automatically balances the upper and lower limit pressures when the cable diameter changes, maintaining constant tension and preventing damage to the cable.

[0033] Disadvantages compared to others:

[0034] In contrast, the spring in the patented design is only used to buffer the pressure of the baffle and cannot achieve dynamic tension adjustment, which can easily lead to the cable being too tight or too loose. Attached Figure Description

[0041] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0042] Please see Figure 1 and Figure 2 and Figure 3 and Figure 4 This utility model provides a technical solution: a power engineering construction cable laying device, including a transport component 1, the transport component 1 including a transport seat 11 and a disassembly plate 12 snapped onto the side of the transport seat 11, the transport component 1 also includes a cable winding reel 13 rotatably connected in the middle of the transport seat 11 and the disassembly plate 12 for storing the cable to be laid, a limiting component 2 set on the inner side of the transport seat 11 to limit the cable to be laid on the outer side of the cable winding reel 13 to prevent it from falling off, and a conveying component 3 set on the top of the inner side of the transport seat 11 to pull the cable and output the cable for laying.

[0043] This design solves the problems of existing technologies, such as the inability to achieve stable and orderly cable output and the ease with which cables can loosen and fall off due to the rapid rotation of the connecting shaft.

[0044] Please see Figure 2 and Figure 3 The limiting component 2 includes a forward and reverse motor 21, which is fixedly installed on the top of the transport seat 11. A threaded rod 211 is fixedly connected to the output end of the forward and reverse motor 21, and the threaded rod 211 is rotatably connected to the slot in the side wall of the transport seat 11 through the forward and reverse motor 21.

[0045] The limiting component 2 also includes a slide 22, which is located inside the transport seat 11 above the cable winding reel 13 and is threadedly connected to the outside of the threaded rod 211.

[0046] The limiting assembly 2 also includes a spring connecting plate 221, the top of which is fixedly connected to the slide 22. The limiting assembly 2 also includes a first support frame 23, which is symmetrically fixedly connected to the bottom of the spring connecting plate 221. The limiting assembly 2 also includes a first roller 231, which is rotatably connected to the middle of the first support frame 23.

[0047] The limiting component 2 also includes a second support frame 24, which is obliquely disposed at the bottom of the inner side of the transport seat 11. A spring ring 242 is provided at the bottom of the second support frame 24. One end of the spring ring 242 is fixedly connected to the second support frame 24, and the other end of the spring ring 242 is fixedly connected to the groove at the bottom of the inner side of the transport seat 11. The limiting component 2 also includes a second roller 241, which is rotatably connected to the top side of the second support frame 24.

[0048] This design allows the rotating first roller 231 and second roller 241 to limit the cable to be laid at the cable winding reel 13 from the upper and lower oblique sides of the cable winding reel 13, respectively. This design can prevent the cable from falling off or shaking at the cable winding reel 13 during the traction and laying process of the cable with the conveying component 3.

[0049] Please see Figure 2 and Figure 4 The conveying assembly 3 includes two sets of rotating shafts 32 that are rotatably connected to the bottom of the inner side of the conveying seat 11. The conveying assembly 3 also includes a toothed disc 321 that is fixedly connected to the top of each rotating shaft 32. The two sets of toothed discs 321 are in contact and are meshing and rotatably connected. The conveying assembly 3 also includes an anti-slip conical roller 33 that is fixedly connected to the outside of each rotating shaft 32.

[0050] The conveying assembly 3 also includes a stepper motor 31, which is fixedly installed inside the transport seat 11. The output end of the stepper motor 31 is fixedly connected to one of the sets of rotating shafts 32.

[0051] The transport assembly 1 also includes casters 111, which are rotatably connected to the bottom of the transport seat 11. The transport assembly 1 also includes handles 112, which are symmetrically fixed to the sides of the transport seat 11.

[0052] This design allows the cable, held between two sets of anti-slip conical rollers 33, to be laid stably by rotating synchronously in the opposite direction with the two sets of anti-slip conical rollers 33 under the action of the stepper motor 31 starting and the meshing rotation of the two sets of toothed discs 321.

[0053] The working principle and usage process of this utility model are as follows:

[0054] First, the cable reel 13 with the cable pre-wound is snapped onto the transport seat 11 by the disassembly plate 12. At this time, the second roller 241 located at the bottom of the transport seat 11 will abut against the cable outside the cable reel 13. Then, one end of the cable is led out from the cable reel 13 and passed between the two sets of anti-slip conical rollers 33. The cable head can be pre-clamped before laying through the gap between the two sets of anti-slip conical rollers 33.

[0055] Then, the forward and reverse motor 21 is started to drive the threaded rod 211 to rotate, which causes the slide 22 and spring connecting plate 221, which are threaded to the outside of the threaded rod 211, to move the first support 23 vertically downward until the first roller 231 abuts against the cable on the outside of the cable winding reel 13.

[0056] When the transport seat 11 is pushed and moved by the caster wheel 111 and the handle 112, the stepper motor 31 can be started and the two sets of gear discs 321 can be meshed and rotated to make the two sets of rotating shafts 32 and anti-slip conical rollers 33 rotate synchronously in opposite directions, thereby making the cable clamped between the two sets of anti-slip conical rollers 33 continuously output and be laid out.

[0057] In particular, as the diameter of the cable roll on the outside of the cable winding reel 13 gradually decreases during laying, the second roller 241 and the first roller 231, under the elastic compression of the spring ring 242 and the spring connecting plate 221, still maintain the function of limiting the cable roll on the outside of the cable winding reel 13.

[0058] The limiting component 2 can prevent the cable from falling off the outside of the cable winding reel 13;

[0059] The conveying component 3 can drive the cable to move with the transport seat 11 to carry out stable output laying work.

[0060] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
