TECHNICAL FIELD

[0001] The utility model relates to the field of pay -off trolley, concretely is a power transmission line guide rope branch device. BACKGROUND

[0002] In the stringing construction of power transmission line, communication line etc., pay -off trolley provides a guiding path for wire or cable. It can ensure that the wire is laid according to the predetermined direction, avoids unnecessary collision or friction of wire and tower, crossing object etc. For example, when the power transmission line construction in mountainous area, the line crosses the valley, forest etc. complex terrain, pay -off trolley can guide the wire to pass smoothly.

[0003] At present, the pay -off trolley for power transmission line has many types, such as single -wheel trolley of one -tow -one, double -wheel trolley of one -tow -two, multi -wheel trolley of one -tow -many etc., and it includes pulley, and each pulley provides independent guiding channel for a guide rope. In the laying process, the guide rope slides on the pulley, and the rotation of the pulley can reduce the friction of the guide rope, so that the guide rope can be laid smoothly.

[0004] A patent with publication number CN207254763U discloses a box medicine sorting device, and the trolley includes a connecting plate, a handle, an intermediate wheel, a rubber wheel, a main shaft, a support frame, a small pulley and a small pulley frame. The connecting plate is arranged above the support frame, and one side is connected with a support frame column shaft, and the other side is provided with a handle and is connected with the other support frame column. The rubber wheel includes six, and is arranged on both sides of the intermediate wheel, and the axis of the rubber wheel coincides with the axis of the intermediate wheel. The main shaft is arranged on the axis of the rubber wheel and the intermediate wheel, and the two ends are fixedly connected with the two columns of the support frame. The small pulley is fixedly arranged at the bottom of the support frame by the small pulley frame, and is engaged with the intermediate wheel. Compared with the prior art, the pay -off trolley provided by the above -mentioned patent has the advantages of simple structure, convenient operation and is very suitable for engineering implementation.

[0005] Whether it is the pay -off trolley provided by the above -mentioned patent or other types of pay -off trolley, it provides a guiding channel for the cable by the pulley, provides support for the wire, and reduces the friction of the wire movement. However, the pay -off trolley still has some defects. For example, the diameters of the wires used in different power transmission lines are different, which means that when laying different size wires, multiple types of pay -off trolleys need to be equipped, because the size of the pulley of each pay -off trolley is fixed, that is, it cannot be adjusted according to the demand, so only when the pay -off trolley including different size pulleys is equipped, the laying of different size wires can be facilitated, and the pulley can be adapted to the wire.

[0032] Embodiment 1

[0033] In order to be able to adjust the state of the wire laying trolley pulley according to the demand, so that it can adapt to different sizes of cables, avoid the need to be equipped with multiple wire laying trolleys including pulleys of different sizes, and reduce the cost of wire laying trolleys for laying power transmission lines. The present embodiment provides a new wire laying trolley, which can be adjusted by the staff according to the actual situation to adjust the state of the pulley, and provides support for cable unwinding. The specific technical scheme is as follows.

[0034] As Figure 1 , Figure 2 , Figure 3As shown, the pay-off trolley (also known as a guide rope distribution device) comprises a frame 1 and a plurality of wheel bodies 2. The frame 1 comprises a top frame 11, a support shaft 13 and a bottom plate 12. The top frame 11 is arranged in a U-shaped structure and provided with a through hole 113 at the top. Therefore, the pay-off trolley can be stably installed on a pole tower under the action of a hanging bracket or the like. The support shaft 13 is arranged at the opening of the top frame 11, and the plurality of wheel bodies 2 are simultaneously sleeved on the support shaft 13, so as to be stably placed under the action of the frame 1, which can stably place the cable and reduce the friction of the cable under the rotation of the wheel body 2. The bottom plate 12 is installed outside the top frame 11 and is sleeved on the end of the support shaft 13 protruding from the top frame 11, which can stably place the top frame 11 on the ground.

[0035] As shown in the Figure 3 In order to stably support the top frame 11 and detach the support shaft 13 according to the needs, the top frame 11 comprises a top plate 112 and two vertical plates 111, and the through hole 113 is arranged at the top of the top plate 112. The end of the lower side of the top plate 112 is provided with a plug-in slot 114, and the fourth fastening bolt is arranged through the plug-in slot 114. The top of the vertical plate 111 is inserted into the plug-in slot 114, and the fourth fastening bolt is arranged through the top of the vertical plate 111. Therefore, under the action of the fourth fastening bolt, the vertical plate 111 and the top plate 112 are stably connected, and the vertical plate 111 and the top plate 112 are conveniently detached according to the needs.

[0036] As shown in the Figure 2 , Figure 3 The bottom of the vertical plate 111 is provided with a through hole, and the first fastening bolt 115 is threadedly arranged through the side wall of the through hole of the vertical plate 111. The end of the first fastening bolt 115 is inserted into the slot 131 arranged at the end of the support shaft 13. Therefore, under the action of the first fastening bolt 115, the support shaft 13 is stably installed on the two vertical plates 111, and the restriction of the support shaft 13 can be released by reversely rotating the first fastening bolt 115. Therefore, the support shaft 13 can be extracted, and the wheel body 2 can be detached.

[0037] As shown in the Figure 5 , Figure 6As shown, in order to realize the adjustable setting of the wheel body 2, the wheel body 2 comprises a main body 21 and a limiting plate set 22. The main body 21 comprises an outer ring plate 211 and an inner ring plate 212, the inner ring plate 212 is fixedly arranged on the inner side of the outer ring plate 211, and a central pipe 213 is arranged through the middle part through a bearing. The end of the central pipe 213 protrudes from the inner ring plate 212. A plurality of insertion slots 131 are arranged on the support shaft 13, which are uniformly distributed along the length direction of the support shaft 13. A third fastening bolt is arranged through the end of the central pipe 213 protruding from the inner ring plate 212 in a threaded manner, and the end of the third fastening bolt is inserted into a certain insertion slot 131. Therefore, the central pipe 213 is stably installed on the support shaft 13, that is, it is stably installed relative to the support shaft 13. In addition, a plurality of insertion slots 131 are arranged, which can stably install the main body 21 at a certain position of the support shaft 13, which means that the position of the main body 21 relative to the support shaft 13 can be adjusted according to the needs to match the laying needs of the cable. It is recorded in the above that the central pipe 213 is arranged through the inner ring plate 212 through a bearing. Therefore, in the case that the central pipe 213 is stably installed on the support shaft 13, it does not affect the rotation of the inner ring plate 212 and the outer ring plate 211 around the shaft.

[0038] As shown in Figure 5 , Figure 7 The limiting plate set 22 is sleeved on the outer side of the main body 21 and comprises two limiting ring plates 221, which are symmetrically arranged and have a width greater than or equal to that of the outer ring plate 211. The side surfaces of the two limiting ring plates 221 close to each other are both arranged as slope surfaces 224, and the low points of the two slope surfaces 224 are arranged in close contact with the outer side surface of the outer ring plate 211. When the two limiting ring plates 221 are arranged in close contact, the cable is arranged through the space formed by the two slope surfaces 224. When the two limiting ring plates 221 are arranged separately, the cable is arranged through the space formed by the outer ring plate 211 and the two slope surfaces 224.

[0039] As shown in Figure 6 , Figure 7As shown, in order to stably install the limiting ring plate 221, a buckle column 222 and an inner threaded tube 223 are fixedly arranged on the inner side of the limiting ring plate 221, the length of the buckle column 222 and the inner threaded tube 223 is equal, and is less than half the width of the outer ring plate 211. A plurality of buckle grooves 214 are arranged on the outer side of the outer ring plate 211, every two buckle grooves 214 are arranged on the same straight line, and the ends thereof away from each other are both arranged as openings, the buckle column 222 and the inner threaded tube 223 are both arranged in the buckle groove 214, thus, under the cooperation of the buckle groove 214, the buckle column 222 and the inner threaded tube 223, the limiting ring plate 221 is stably and adjustably installed on the outer ring plate 211. The two inner threaded tubes 223 of the two limiting ring plates 221 are threadedly sleeved on the same bidirectional screw rod 225, the bidirectional screw rod 225 penetrates the end wall shared by the two buckle grooves 214, thus, the relative movement of the two limiting ring plates 221 can be controlled by rotating the bidirectional screw rod 225, which provides convenience for accommodating cables of different sizes.

[0040] Embodiment 2

[0041] As Figure 4 shown, on the basis of embodiment 1, if the pay-off trolley is moved by personnel, the labor intensity of the workers will be increased due to the large mass of the pay-off trolley, therefore, in order to reduce the labor intensity of the workers, the bottom plate 12 is arranged in an adjustable state in this embodiment, specifically, a threaded groove 116 is arranged on the bottom of each side of the two vertical plates 111 away from each other, and at least one threaded groove 116 is arranged. When one threaded groove 116 is arranged, the threaded groove 116 is located directly above the through hole. In addition, a second fastening bolt 122 is threadedly penetrated and arranged on the top of the bottom plate 12, when the end of the second fastening bolt 122 is threadedly inserted into the threaded groove 116, the bottom plate 12 and the vertical plate 111 are arranged on the same straight line, and are distributed on the two sides of the support shaft 13, at this time, under the action of the support plate 121 on the bottom of the bottom plate 12, the top frame 11 can be stably placed on the ground. When the second fastening bolt 122 is rotated to release the limitation of the bottom plate 12 and the vertical plate 111, the bottom plate 12 can be rotated under the action of an external force, because, it is convenient for the workers to tilt and pull the pay-off trolley, and the movement of the pay-off trolley is realized under the rotation of the wheel body 2, and the current situation of moving by personnel is changed. In order to avoid the influence of the bottom plate 12 on the movement of the pay-off trolley, a threaded groove 116 can also be arranged directly below the through hole, thus, when the bottom plate 12 is placed parallel to the vertical plate 111 after being rotated by 180°, it is stably placed on the side of the vertical plate 111.

[0042] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range.
