Description

Technical Field

[0001] The utility model belongs to the technical field of overhead line conductors, and particularly relates to an overhead line conductor spreading device. Background Art

[0002] Overhead line conductor deployment refers to the process of unfolding the conductor from the wire drum and erecting it on the pole or tower during the construction of the overhead transmission line. In the existing overhead transmission lines, most of them use one or two conductors for deployment. The deployment method of one or two conductors requires multiple deployments and connections, a long construction period, and low project efficiency, which may lead to project delays and increased costs. Due to the increase in the number of conductor deployments, construction personnel need to frequently operate at high altitudes, increasing the risk of accidents. In overhead transmission lines, the deployment method of one or two conductors requires more construction personnel and equipment to participate, and the construction is more difficult. At the same time, due to the small number of conductors, the tension and sag control of the conductors are also more difficult. The deployment method of one or two conductors requires more materials and human resources, resulting in increased project costs. In the long run, the economic benefits of this method are relatively low. In summary, in the existing overhead transmission lines, the deployment method of one or two conductors has disadvantages such as large engineering volume. In order to solve this problem, we have developed an overhead line conductor deployment device. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide an overhead line conductor deployment device to solve the problems raised in the above-mentioned background technology.

[0004] The utility model is realized by the following technical scheme: an overhead line conductor laying device, comprising: a bottom plate, a pushing frame and a wire drum storage slot, the pushing frame is installed in front of the bottom plate, side vertical plates are respectively arranged on the left and right sides of the rear upper surface of the bottom plate, and a transmission guide wheel is arranged in the middle above the two side vertical plates;

[0005] A plurality of guide wheel grooves are provided in the middle of the transmission guide wheel, a driving motor is arranged on the upper left side of the left side vertical plate, an outer sleeve is connected to the right side of the output shaft of the driving motor, and an outer fixing plate is installed on the outer side of the right end of the driving motor;

[0006] A left connecting shaft is provided on the right side of the outer sleeve, a transmission inner rod is installed inside the outer sleeve, a plurality of groups of tooth grooves are provided around the left side surface of the left connecting shaft, a plurality of groups of teeth are provided around the right side surface of the transmission inner rod, a telescopic push rod is respectively installed above and below the right side surface of the outer fixed plate, and a bearing is respectively installed above the right side surfaces of the two side vertical plates.

[0007] As a preferred embodiment, the front side of the upper surface of the bottom plate is recessed downward to form a wire reel storage groove, and a fixed base is respectively installed under the two side vertical plates.

[0008] As a preferred embodiment, the two fixed bases are respectively fixed to the bottom plate, a right connecting shaft is installed in the middle of the right side surface of the transmission guide wheel, and the right side of the right connecting shaft is connected to the inner side of the right bearing.

[0009] As a preferred embodiment, the left connecting shaft passes through the inner side of the left bearing and is connected to the middle of the left side surface of the transmission guide wheel, and the inner side of the left bearing is fixed to the outer side of the left connecting shaft.

[0010] As a preferred embodiment, the right ends of the two telescopic push rods are respectively fixed to the left side surface of the left vertical plate, and the transmission inner rod is meshed with multiple groups of tooth grooves through multiple groups of teeth.

[0011] As a preferred embodiment, the right-view surfaces of the plurality of groups of teeth and the left-view surfaces of the plurality of groups of tooth grooves are all distributed in a ring shape, and the driving motor is a speed-regulating motor.

[0012] Before construction, multiple reels of conductors are set up, and multiple conductors of multiple conductor reels are respectively wound into multiple guide wheel grooves, and then the conductors are pulled by the conductor pulling device on the upper side of the pole tower, and the drive motor can be started at the same time. The output shaft of the drive motor can drive the left connecting shaft to rotate through the outer sleeve and the transmission inner rod, and the left connecting shaft drives the transmission guide wheel to rotate, so as to realize the simultaneous deployment of multiple conductors. The speed of the drive motor can be adjusted according to actual needs. When the left connecting shaft rotates, it can drive the inner side of the left bearing to rotate. When the transmission guide wheel rotates, it can drive the right bearing to rotate through the right connecting shaft. Through the above steps, the final effect is that multiple conductors can be deployed at the same time, which greatly improves the construction efficiency and reduces the construction time and labor cost. The conductors in multiple guide wheel grooves can be deployed at the same speed and tension, ensuring the consistency and stability of the conductor deployment. Since multiple conductors are deployed at the same time, the tension borne by each conductor is smaller, and the mutual friction and extrusion between the conductors can be prevented in the guide wheel grooves to prevent the conductors from being damaged. At the same time, the deployment speed and tension of the conductors can be accurately controlled by the drive motor, making the deployment process more stable and controllable.

[0013] As a preferred embodiment, a universal wheel is installed at each of the four corners of the lower surface of the base plate, the telescopic push rod is an electric push rod, the two telescopic push rods are a synchronization mechanism, and the diameter length of the outer sleeve is greater than the diameter length of the left connecting shaft.

[0014] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by arranging a transmission guide wheel, a guide wheel groove, a driving motor, a left connecting shaft, a right connecting shaft and a bearing, it is possible to drive the transmission guide wheel to rotate, so that multiple wires can be respectively laid out in multiple guide wheel grooves. Compared with the method of laying out one or two wires, multiple wires can be laid out at the same time, which can greatly improve the efficiency of wire laying, reduce construction time and labor costs, and multiple guide wheel grooves can make each wire bear more uniform tension, reduce stress concentration and fatigue damage of the wire, and increase the service life of the wire. The driving motor can accurately control the laying speed and tension of the wire, making the laying process more stable and controllable, reducing construction risks, and because each wire is laid out in an independent guide wheel groove, friction and mutual interference between the wires are reduced, and the risk of wire damage is reduced;

[0015] By providing an outer sleeve, an inner transmission rod, teeth, a left connecting shaft, a tooth groove, an outer fixed plate and a telescopic rod, the teeth can be driven to disconnect from the tooth groove through the telescopic push rod, thereby facilitating the adjustment of the transmission gear to become a driven wheel. In some cases, such as when the tension of the wire is small or a lower deployment speed is required, the transmission gear can be converted into a driven wheel, and the movement of the wire itself can be used to drive the transmission guide wheel to rotate, thereby reducing the energy consumption of the drive motor. According to different construction conditions and requirements, the working mode of the transmission guide wheel can be flexibly selected to adapt to different wire deployment needs.
