Description

Portable electric wire pulling device {Portable pulling device}

The present invention relates to a portable electric wire pulling machine, and more particularly, to a portable electric wire pulling machine optimized for a pulling operation that requires a constant force in a portable manner because a plurality of rollers are connected in an 11-shape shape and can be simultaneously moved by a motor.

In general, in large buildings and workplaces, various cables are installed to supply power to each room and to various equipment and to transmit data.

To this end, conventionally, a method of pulling a thick and heavy cable using equipment such as a winch has been used, but there is a problem that the lifting speed is slow and the cable is damaged due to a strong tension applied to the cable.

In addition, the conventional cable pulling device as shown in FIG. 1 has a structure in which the upper and lower surfaces of the main cover having a box shape with an open lower surface are shielded by an upper plate and a lower plate, respectively, and are elastic on the outer circumferential surface of the wheel. A rotary tire molded from ash is inserted. In addition, a handle nut bracket that is mounted on one side of the motor that is interlocked with the operating force of the handle is provided, and a distance adjusting means that moves linearly in connection with the forward/reverse rotation operation of the handle is provided.

However, in the prior art, since the user must rotate the handle to adjust the spacing of the rotating part to correspond to the thickness of the cable to be installed according to the thickness of the cable, it is difficult to adjust the spacing of the rotating part unless the skilled worker damages the cable to be installed, There was a problem that the cable was not transferred smoothly.

In addition, even for skilled workers, when the function of the rotating part is deteriorated due to wear or the like due to frequent use, and mechanical clearance occurs, there is a problem that the cable cannot be transferred at a certain pressure.

In addition, when the pulling of the cable is stopped due to an unexpected situation, there is a problem in that a groove is generated as a certain position of the cable is worn due to the rotating tire that still rotates.

In addition, when a thick cable is inserted, a cable with a thickness thinner than that is not in close contact with the roller, so it is impossible to transfer it at the same time.

The conventional inventor Korean Patent No. 2035449 relates to a wear-resistant modular mobile cable pulling system in which a cable pulling module is installed on the upper part of the base to pull and install the cable, wherein the cable pulling modules are symmetrical to each other and two are installed between the two. A cable caught in the cable is towed by the operation of the cable pulling module, the cable pulling module is rotatably installed between two support plates, a plurality of pushing rollers for pushing the cable by rotating in the same direction; A driven gear installed at one end of the pushing roller; A direction change gear installed between the driven gears to transmit power so that the driven gears rotate in the same direction between the driven gears; A connecting gear coupled to any one of the gears to transmit power of the driving means to the gear; And a power transmission means for transmitting the power of the driving means to the connection gear, wherein a moving means mounting hole is formed in the base, a moving means is installed, and cables are provided at both ends of the cable pulling module to the cable pulling module. Further comprising a cable guide means for guiding, wherein the cable guide means is a support bar installed perpendicular to the base; Two guide rollers installed so that both ends are supported on the support bar by the lifting body raised and lowered along the support bar; And it relates to a modular mobile cable pulling system consisting of a fixing means for fixing the height-adjusted lifting body.

However, there is a problem in that the size is large and parts related to the operation of the guide roller are particularly complex, and replacement is not easy because a plurality of modules are organically connected.

Korean Patent Registration No. 1495490, which is a conventional inventor, is provided with an upper rotating sprocket and an upper idle sprocket spaced apart, and a chain loop in which a plurality of transfer plates into which a metal reinforcing part is inserted is spaced apart from each other and is fixedly coupled to the upper rotating sprocket and the upper idle sprocket. An upper conveying unit wound around the outside; The lower rotating sprocket and the lower idle sprocket are provided at a distance, and a chain loop in which a plurality of conveying plates into which a metal reinforcing part is inserted is spaced apart from each other and fixedly coupled is wound around the outer side of the lower rotating sprocket and the lower idle sprocket, and the upper conveying part A lower transfer unit provided at the lower side; A driving motor unit for rotating the upper and lower transfer parts; It is provided in each of the left and right sides of the lower conveying part and in the center, and the cable is inserted between the upper conveying part and the lower conveying part, so that the left and right and the front and rear of the lower conveying part can be separately raised and lowered. It can be transferred by pressing with pressure, the upper and lower sides are hinged to enable free rotation to facilitate lifting and lowering operation of a shock absorber unit; And a guide roller provided on the side of the lower conveying unit and in contact with the guide surface of the main body, and controlling an inclined range of the lower conveying unit during the lifting and lowering operation of the buffer shock absorber unit.

However, the size is large, the internal parts are expensive, and it is difficult to downsize.

In addition, the connection between detailed parts is complicated and modularization is impossible, resulting in a problem that requires a lot of repair costs.

In addition, the area occupied by one device is large due to its large planarity, and when these devices are disposed horizontally so as to be adjacent to each other, they occupy a large plane area, and thus a lot of time and transportation equipment are required for storage and transportation.
