Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a high-efficiency construction tool for power engineering. Background Technology

[0002] In power engineering construction, cable laying and retrieval are frequent and critical operations, especially in substation construction, distribution network renovation, temporary power supply, and emergency repairs, where it is necessary to frequently change cable rollers of different specifications for laying or retrieving. Traditional cable construction tools mostly use fixed drum structures or simple brackets to support the cable rollers, which have many technical defects: First, the long shaft rotating rod is usually a cantilever structure, driven by a motor only at one end, with no effective support at the other end. This makes it easy for the cable roller to bend, deform, vibrate, or wobble when bearing heavy cable rollers, seriously affecting the rotational stability and even causing equipment damage. Second, the installation and disassembly of cable rollers is cumbersome, usually relying on bolt fixing or key connections, requiring alignment and adjustment, which is time-consuming and labor-intensive, and cannot meet the needs of rapid roller changing on the construction site. In addition, cable rollers are prone to jumping or axial displacement during high-speed start-up and shutdown or sudden load changes, and the lack of effective clamping and limiting devices poses safety hazards. Existing equipment generally lacks dynamic clamping and auxiliary support functions for cable rollers during operation, resulting in low construction efficiency, high labor intensity, and poor safety. Therefore, we propose a high-efficiency construction tool for power engineering. Utility Model Content

[0003] The main purpose of this utility model is to provide an efficient construction tool for power engineering, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A high-efficiency construction tool for power engineering includes a base plate, a fixed frame fixedly installed on one side of the upper end of the base plate, a winding and unwinding mechanism rotatably connected to the fixed frame, a cable roller detachably installed on the winding and unwinding mechanism, a support body detachably installed on the upper end of the base plate away from the fixed frame, and the support body is slidably engaged with the winding and unwinding mechanism, and a pressing mechanism fixedly installed on the top of the fixed frame, and the pressing mechanism is located above the cable roller.

[0006] The winding and unwinding mechanism includes a winding discharge machine, which is fixedly installed on one side of the fixed frame. A rotating rod is fixedly connected to the output end of the winding discharge machine, and the rotating rod is movably installed to the fixed frame through a bearing. A positioning plate is fixedly connected to the rotating rod, and a spline is integrally formed on the outer surface of the rotating rod.

[0007] Preferably, the cable roller has an internal mounting keyway that is slidably connected to the spline, and the cable roller is slidably sleeved on the rotating rod through the mounting keyway.

[0008] By adopting the above technical solution, the circumferential fixing and axial sliding installation between the cable roller and the rotating rod are achieved through the sliding fit of the spline and the mounting keyway. This not only ensures the reliable transmission of torque but also facilitates the quick assembly and disassembly of the cable roller, thus improving construction efficiency.

[0009] Preferably, one end of the cable roller is fixedly connected to a plurality of positioning rods, and the plurality of positioning rods are arranged in a circular array. The positioning disk has a plurality of positioning holes that engage with the positioning rods. The positioning rods engage in the positioning holes to fix the cable roller to one side of the positioning disk.

[0010] By adopting the above technical solution, the positioning rod and the positioning hole are engaged to achieve rapid positioning and axial limiting between the cable roller and the positioning plate, thereby enhancing connection stability and preventing loosening or displacement during rotation.

[0011] Preferably, the upper end of the base plate has a mounting hole on the side away from the fixing frame; the support body includes a support frame, a positioning sleeve is rotatably connected to the upper part of the support frame, a connecting keyway that slides and engages with the spline is provided in the positioning sleeve, and a fixing screw that is threadedly connected to the mounting hole is inserted and connected to the support frame.

[0012] By adopting the above technical solution: the main support body is detachably fixed to the base plate by fixing screws, and its positioning sleeve is slidably engaged with the spline through the connecting keyway, so as to achieve auxiliary support for the far end of the rotating rod and improve the overall structural rigidity and rotational stability.

[0013] Preferably, the clamping mechanism includes a stand, which is fixedly installed on the top of the fixed frame. An electric telescopic rod is fixedly installed on the stand. The output end of the electric telescopic rod passes through the stand and is fixedly connected to a pressure plate. Two guide rods are fixedly installed on the upper end of the pressure plate, and both guide rods are slidably connected to the stand.

[0014] By adopting the above technical solution: the electric telescopic rod drives the pressure plate to move up and down, and the guide rod provides guidance to ensure that the pressure plate presses down smoothly and vertically, thereby realizing automatic pressing and releasing of the cable roller and improving operational safety and automation.

[0015] Preferably, the pressure plate has an arc-shaped structure and is located directly above the cable roller, and the inner surface of the pressure plate is integrally formed with anti-slip ridges.

[0016] By adopting the above technical solution: the arc-shaped pressure plate has a high degree of fit with the outer periphery of the cable roller, and the anti-slip ridges on the inner surface increase the friction, effectively preventing the cable roller from jumping or slipping during operation, thus enhancing the pressing effect and operational safety.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. By setting up a fixed frame and a detachable support body, and combining the sliding fit structure of splines, mounting keyways, and connecting keyways, double-end support for the rotating rod is achieved. This effectively solves the technical problems of excessively long cantilevered rotating rods and insufficient support in traditional equipment. Specifically, the cable roller slides onto the rotating rod through its internal mounting keyway along the spline. With the annular snap-fit ​​between the positioning rod and the positioning hole, the cable roller can be quickly installed axially and fixed circumferentially without the need for bolt tightening or complex alignment, greatly improving the efficiency of roller changing. At the same time, the positioning sleeve on the support body slides and snaps onto the spline on the outer surface of the rotating rod through the connecting keyway, providing mechanical support while maintaining synchronous rotation, avoiding slippage, and ensuring coaxiality and stability during the support process. This double-end support structure significantly enhances the overall rigidity and bending resistance of the rotating rod, effectively suppressing vibration and sway during heavy loads or high-speed operation, improving the stability and service life of the equipment. It is particularly suitable for construction sites with heavy cable rollers, improving the applicability and operational reliability of the equipment.

[0019] 2. A clamping mechanism is installed at the top of the fixed frame. This mechanism includes a pressure plate driven by an electric telescopic rod, which automatically presses down above the cable roller during equipment operation to achieve dynamic clamping of the cable roller. This effectively prevents it from jumping, axially slipping, or falling off during start-up, speed changes, or sudden load changes. The pressure plate adopts an arc-shaped structure that matches the outer circumference of the cable roller, and anti-slip ridges are integrally formed on its inner surface, increasing the contact area and friction, further enhancing the limiting effect, and avoiding slippage or displacement due to insufficient clamping force. The extension and retraction of the electric telescopic rod is automatically triggered by the control system. The clamping process is completed before startup and automatically lifted after operation, achieving automated control of the clamping process, reducing manual intervention and improving ease of operation. In addition, the guide rods connected to both ends of the clamping plate slide in cooperation with the upright frame, providing precise vertical guidance for the clamping plate, ensuring uniform distribution of clamping force, avoiding uneven load or local wear, and improving the motion accuracy and long-term stability of the clamping mechanism. This design not only significantly improves the safety of the equipment in high-load, high-frequency operating environments, but also effectively protects the cable insulation layer and cable roller structure from abnormal vibration damage, and has important practical value and promotion prospects.

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A high-efficiency construction tool for power engineering includes a base plate 1, a fixed frame 2 fixedly installed on one side of the upper end of the base plate 1, a winding and unwinding mechanism 3 rotatably connected to the fixed frame 2, a cable roller 4 detachably installed on the winding and unwinding mechanism 3, a support body 5 detachably installed on the upper end of the base plate 1 away from the fixed frame 2, and the support body 5 is slidably engaged with the winding and unwinding mechanism 3, and a pressing mechanism 6 is fixedly installed on the top of the fixed frame 2, and the pressing mechanism 6 is located above the cable roller 4.

[0030] In this embodiment, the winding and unwinding mechanism 3 includes a winding and unwinding machine 31, which is fixedly installed on one side of the fixed frame 2. A rotating rod 32 is fixedly connected to the output end of the winding and unwinding machine 31, and the rotating rod 32 is movably installed on the fixed frame 2 through a bearing. A positioning plate 33 is fixedly connected to the rotating rod 32, and a spline 34 is integrally formed on the outer surface of the rotating rod 32. The cable roller 4 has a mounting keyway 41 that is slidably connected to the spline 34 inside, and the cable roller 4 is slidably sleeved on the rotating rod 32 through the mounting keyway 41. A plurality of positioning rods 42 are fixedly connected to one end of the cable roller 4, and the plurality of positioning rods 42 are fixedly connected to the rotating rod 32. The insertion rods 42 are arranged in a circular array. The positioning plate 33 has multiple positioning holes 35 that engage with the positioning insertion rods 42. The positioning insertion rods 42 are engaged in the positioning holes 35 to fix the cable roller 4 to one side of the positioning plate 33. The upper end of the base plate 1 has a mounting hole 11 on the side away from the fixing frame 2. The support body 5 includes a support frame 51. The upper part of the support frame 51 is rotatably connected to a positioning sleeve 52. The positioning sleeve 52 has a connecting keyway 521 that engages with the spline 34. The support frame 51 is threaded with a fixing screw 53 that is threaded to the mounting hole 11.

[0031] Through the above solution: by setting up a fixed frame 2 and a detachable support body 5, and combining the sliding fit structure of spline 34 with mounting keyway 41 and connecting keyway 521, double-end support for the rotating rod 32 is achieved, effectively solving the technical problems of excessively long rotating rod cantilever and insufficient support in traditional equipment. Specifically, the cable roller 4 slides on the rotating rod 32 along the spline 34 through its internal mounting keyway 41, and with the annular snap-fit ​​between the positioning rod 42 and the positioning hole 35, the cable roller can be quickly installed axially and fixed circumferentially without the need for bolt tightening or complex alignment. This significantly improves roller changing efficiency. Meanwhile, the positioning sleeve 52 on the support body 5 is slidably engaged with the spline 34 on the outer surface of the rotating rod 32 via the connecting keyway 521, providing mechanical support while maintaining synchronous rotation to prevent slippage and ensure coaxiality and stability during the support process. This double-end support structure significantly enhances the overall rigidity and bending resistance of the rotating rod 32, effectively suppressing vibration and sway during heavy loads or high-speed operation, improving the stability and service life of the equipment. It is particularly suitable for construction sites with heavy-duty cable rollers, expanding the equipment's applicability and operational reliability.

[0032] In this embodiment, the pressing mechanism 6 includes a stand 61, which is fixedly installed on the top of the fixed frame 2. An electric telescopic rod 63 is fixedly installed on the stand 61. The output end of the electric telescopic rod 63 passes through the stand 61 and is fixedly connected to a pressure plate 62. Two guide rods 64 are fixedly installed on the upper end of the pressure plate 62, and both guide rods 64 are slidably connected to the stand 61. The pressure plate 62 has an arc-shaped structure and is located directly above the cable roller 4. The inner surface of the pressure plate 62 is integrally formed with anti-slip convex strips.

[0033] Through the above solution: By setting a clamping mechanism 6 on the top of the fixed frame 2, it can automatically press down above the cable roller 4 during equipment operation, realizing dynamic clamping of the cable roller, effectively preventing it from jumping, axially slipping or falling off during start-up, speed change or sudden load change. The pressure plate 62 adopts an arc-shaped structure that matches the outer periphery of the cable roller 4, and anti-slip ridges are integrally formed on its inner surface, increasing the contact area and friction, further enhancing the limiting effect, and avoiding slippage or displacement due to insufficient clamping force. The extension and retraction of the electric telescopic rod 63 is automatically triggered by the control system, which can be done before the motor starts. After the clamping is completed, the plate automatically lifts up, achieving automated control of the clamping process, reducing manual intervention and improving ease of operation. In addition, the guide rods 64 connected to both ends of the clamping plate 62 slide in cooperation with the upright frame 61, providing precise vertical guidance for the clamping plate, ensuring uniform distribution of clamping force, avoiding uneven load or local wear, and improving the motion accuracy and long-term stability of the clamping mechanism. This design not only significantly improves the safety of the equipment in high-load, high-frequency operating environments, but also effectively protects the cable insulation layer and cable roller structure from abnormal vibration damage, and has important practical value and promotion prospects.

[0034] It should be noted that this utility model is an efficient construction tool for power engineering. During use, the base plate 1 is first placed on a stable surface. The operator then installs the cable roller 4 to be wound or unwound. During installation, the multiple positioning pins 42 at one end of the cable roller 4 are aligned with the positioning holes 35 of the positioning disc 33 on the fixed frame 2. The cable roller 4 is then slidably fitted onto the rotating rod 32 along the spline 34 direction until the positioning pins 42 are fully inserted into the positioning holes 35, achieving circumferential fixation and axial limiting between the cable roller 4 and the rotating rod 32, ensuring reliable power transmission. Subsequently, the support frame 51 of the supporting body 5 is moved to the side of the base plate 1 away from the fixed frame 2, aligning the connecting keyway 521 inside the positioning sleeve 52 with the spline 34 on the outer surface of the rotating rod 32. The supporting body 5 is then slid axially, allowing the spline 34 to simultaneously insert into the connecting keyway 521, providing auxiliary support to the far end of the rotating rod 32. At this point, the fixing screws 53 are passed through the support frame 51 and screwed into the mounting holes 11 on the base plate 1 to complete the installation. The detachable fixing of the support body 5 enhances the overall rigidity and stability of the rotating rod 32 during high-speed or heavy-load operation, preventing deflection or vibration. After the cable roller 4 is installed, the clamping mechanism 6 is activated, and the electric telescopic rod 63 extends downward after being powered on, driving the pressure plate 62 to move vertically downward along the guide rod 64 until the inner surface of the arc-shaped pressure plate 62 is in contact with the outer circumferential surface of the cable roller 4. The integrally formed anti-slip convex strip on its inner surface contacts the cable roller 4, increasing friction and preventing the cable roller 4 from jumping, shifting, or even falling off during start-up, shutdown, or load changes, thus improving the safety and reliability of the equipment operation. During cable winding or unwinding operations, the winding and unwinding machine 31 is activated, driving the rotating rod 32 to rotate. Through the cooperation of the spline 34 and the mounting keyway 41, the torque is transmitted to the cable roller 4, realizing automatic winding or controllable unwinding of the cable. The positioning sleeve 52 of the support body 5 is slidably engaged with the spline 34, ensuring rotational synchronization and sharing the load on the cantilever end of the rotating rod 32, thus improving rotational stability.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
