DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a railway overhead line system construction positioning pulley, including positioning pulley 1, the upper portion of positioning pulley 1 is provided with cable storage frame 3, still include: distance adjusting mechanism 4, distance adjusting mechanism 4 sets up in the upper portion of positioning pulley 1, and distance adjusting mechanism 4 includes first sliding arm 5 and second sliding arm 6, and first sliding arm 5 and second sliding arm 6 are all slidingly connected in the slide way of positioning pulley 1, and first sliding arm 5 and second sliding arm 6 are symmetrically arranged, and the upper surface of positioning pulley 1 is fixed with two rotating seats 9, and two rotating seats 9 are rotatably connected with two-way threaded rod 7, and one end of two-way threaded rod 7 is fixed with operating knob 8, and two-way threaded rod 7 is symmetrically provided with two-way helical thread on the surface, and first sliding arm 5 and second sliding arm 6 are all screw connected with two-way threaded rod 7, because two-way threaded rod 7 is symmetrically provided with two-way helical thread on the surface, so that first sliding arm 5 and second sliding arm 6 symmetrically arranged on two-way threaded rod 7 are close to each other or away from each other;

[0023] The wire guiding mechanism 11 is arranged on the distance adjusting mechanism 4, and the wire guiding mechanism 11 comprises a fixed shell 12, three wire outlet guide wheels 13 and a horizontal support 16. The fixed shell 12 is arranged on one side of the cable storage rack 3, the three wire outlet guide wheels 13 are rotationally connected to the inner region of the fixed shell 12, and the horizontal support 16 is slidably penetrated through the inner region of the fixed shell 12. The three wire outlet guide wheels 13 are arranged at three vertices of a triangle in the inner region of the fixed shell 12. A through hole 15 is formed in one side surface of the fixed shell 12 and is adapted to the sliding of the horizontal support 16. Two limiting knobs 14 are threadedly connected to the threaded portion of the horizontal support 16 and are arranged on the two sides of the fixed shell 12, respectively. The cable is drawn out through the three wire outlet guide wheels 13 in the fixed shell 12. Since the fixed shell 12 keeps the fixed position in front of the cable storage rack 3, the wire outlet of the cable storage rack 3 is always drawn out from the wire outlet guide wheels 13.

[0024] Further as Figure 4 illustred, it is worth noting that the opposite side surfaces of the first sliding arm 5 and the second sliding arm 6 are fixed with a bearing sleeve base 10, and one end of the horizontal support 16 is fixed to the side surface of the bearing sleeve base 10.

[0025] Further as Figure 1 illustrated, it is worth noting that the lower end surface of the positioning trolley 1 is provided with positioning rollers 2 for walking along the railway track, and the shaft neck of the cable storage rack 3 is rotationally connected in the bearing sleeve base 10.

[0026] The present scheme has the following working process: before use, the operating knob 8 is rotated to drive the bidirectional threaded rod 7 to rotate on the two rotating bases 9. Since the surface of the bidirectional threaded rod 7 is symmetrically provided with bidirectional helical threads, the first sliding arm 5 and the second sliding arm 6 symmetrically arranged on the bidirectional threaded rod 7 are close to or away from each other. The adjustable spacing between the first sliding arm 5 and the second sliding arm 6 can adapt to the rotational assembly application of the cable storage rack 3 of different width specifications. The synchronous adjustment of the first sliding arm 5 and the second sliding arm 6 can keep the center application of the cable storage rack 3 above the positioning trolley 1. In addition, the first sliding arm 5 and the second sliding arm 6 can limit the rotation of the cable storage rack 3 once the shaft neck of the cable storage rack 3 is clamped during the contraction process, so as to prevent the trouble of the cable outlet caused by the rotation of the cable storage rack 3 during the bumping transportation process;

[0027] When the cable is drawn out, the cable is drawn out through three outgoing cable guide wheels 13 in the fixed shell 12. Since the fixed shell 12 keeps the fixed position in front of the cable storage rack 3, the outgoing cable of the cable storage rack 3 is always drawn out from the outgoing cable guide wheels 13, so as to reduce the trouble of cable direction deviation caused by the change of outgoing cable position of the cable storage rack 3, and further ensure the stability of the cable storage rack 3 during the pay-off process. Moreover, the fixed shell 12 can slide left and right along the horizontal support 16 and lock the position by using two limiting knobs 14, so as to adjust the position of the outgoing cable guide wheels 13 left and right, so as to adapt to the catenary erection position.
