Description

TECHNICAL FIELD

[0001] The utility model relates to a stringing device technical field, concretely is a stringing device of electric power engineering construction. BACKGROUND

[0002] In electric power engineering construction, in order to transport electric power or temporary force, need to take out the cable from the cable reel, lay to the underground cable trench or cable conduit.

[0003] The prior art means of taking out the cable from the cable reel is usually to erect the cable reel on the frame, so that the cable reel can rotate, and the end of the cable pulled out outward can take out the cable to the required length. During the cable is pulled out from the cable reel, there is no effective support, so that the cable will be in a drooping state, and is pulled out outward with friction to the ground. This cable taking-out mode is easy to cause the abrasion of the cable. Although the pulled-out cable is placed on the support plate outside the frame to reduce the friction force generated by the contact of the cable with the ground, but the support plate is separated from the frame, and the position of the support plate also needs to be adjusted separately when adjusting the frame, which is inconvenient to use. And the support plate is placed on the ground, and the position is relatively low, and the erection height of the pulled-out cable cannot be adjusted according to the cable reel of different sizes or types, so that the cable separated from the support plate will also contact the ground and cause unnecessary abrasion.

DETAILED DESCRIPTION

[0026] Referring to Figure 1 ,Figure 3 and Figure 4 As shown, a power line erection device for power engineering construction includes a frame 1 and two arc-shaped grooves 11 for erecting cable reels 2. The two arc-shaped grooves 11 are coaxially arranged. A front crossbar 12 located below the arc-shaped grooves 11 is provided on one side of the frame 1. The length direction of the front crossbar 12 is parallel to the axis of the arc-shaped grooves 11. A first support rod 3 with adjustable length is rotatably mounted on the front crossbar 12. A second support rod 4 is rotatably mounted on the end of the first support rod 3 away from the front crossbar 12. The first support rod 3 includes a first sleeve 31 and a second sleeve 32 that are plugged into each other. The first sleeve 31 and the second sleeve 32 are fastened together by a fastening bolt 33 to realize the length adjustment of the first support rod 3.

[0027] Among them, see Figure 2 As shown, a guide seat 5 is provided on the upper part of the first support rod 3 away from the front crossbar 12. The guide seat 5 has the following structure: it includes two symmetrically arranged guide plates 51 and a base plate 52 located below the guide plates 51. The two guide plates 51 are vertically connected to both sides of the base plate 52. The inner surfaces of the two guide plates 51 and the upper surface of the base plate 52 form a guide groove 53. The length direction of the guide groove 53 is consistent with the unwinding direction of the cable reel 2. A rotating roller 6 is provided in the guide groove 53. The two ends of the rotating roller 6 are rotatably connected to the lower inner sides of the two guide plates 51. At least two sets of rotating rollers 6 are provided. The two sets of rotating rollers 6 are respectively arranged on both sides of the guide plate 51 along the length direction. The two sets of rotating rollers 6 can provide better support and guidance for the cable, increase the contact points and contact area with the cable, and reduce the friction between the guide seat 5 and the cable.

[0028] To increase the contact points between the rotating roller 6 and the cable being pulled out, the rotating roller 6 is parallel to the axis and the length direction of the front crossbar 12. The plane where the axis of the rotating roller 6 closest to the frame 1 is located is higher than the plane where the axis of the other rotating roller 6 is located. This arrangement is consistent with the trajectory of the cable moving from high to low, so that the cable can contact the two rotating rollers 6 at different heights at the same time.

[0029] In the above structure, the ends of the first support rod 3 and the second support rod 4 are hinged, and one end of the second support rod 4 is in contact with the ground. This makes the height of the guide seat 5 at the hinge of the first support rod 3 and the second support rod 4 adjustable. This allows the height of the guide seat 5 to be adjusted according to different sizes of cable reels 2, so that the pulled-out cable can be transported to the cable trench or cable pipe through the support and guidance of the guide seat 5, which can reduce the wear phenomenon caused by the cable surface contacting the ground. The first support rod 3 is rotatably connected to the front crossbar 12, so that the positions of the first support rod 3 and the second support rod 4 can be moved together when the frame 1 is moved, and the position of the guide seat 5 does not need to be adjusted repeatedly.

[0030] For larger cable reel 2, the guide seat 5 and cable reel 2 spacing should be adjusted to a larger spacing, in order to facilitate the cable through the guide seat 5 to the cable trench for delivery, for this, the longest length of the first support rod 3 is greater than the vertical spacing between the front cross bar 12 and the ground.

[0031] In order to facilitate the range of the first support rod 3 and the second support rod 4, improve the adjustable position range of the guide seat 5, suitable for a variety of different size or model of cable reel 2, the length of the second support rod 4 is greater than the longest length of the first support rod 3.

[0032] In order to avoid the second support rod 4 supported on the ground when the phenomenon of slip, reduce the cable in the guide seat 5 to move when the guide seat 5 height position change, set the second support rod 4 away from the first support rod 3 one end is provided with the bottom bar 7 with the ground, the bottom plate 52 with the second support rod 4 vertical, the lower end of the bottom bar 7 and the ground contact, because the bottom bar 7 and the second support rod 4 vertical, can make the second support rod 4 better support on the ground. The length direction of the bottom bar 7 and the width direction of the second support rod 4 are consistent, the width of the bottom bar 7 is 1-10㎝, in order to the bottom bar 7 can be inserted into the ground, play a fixed second support rod 4 position role.

[0033] In order to facilitate the second support rod 4 can be better supported on the ground, the first support rod 3 and the second support rod 4 angle range in 45°-150°, wherein the first support rod 3 and the second support rod 4 angle range in 90°-150°, need to insert the bottom bar 7 in the ground or brick joint, or through the fastener with the ground fastening connection, avoid the second support rod 4 lower end of the phenomenon of slip.
