Abstract
The utility model discloses an additional line homing balance supporting device. The additional line homing balance supporting device comprises a middle connection bolt and middle connection pieces which are connected with an additional line shoulder frame. Each middle connection piece is connected with one end of an aluminum alloy supporting tube, and the other end of the aluminum alloy supporting tube is provided with a single ear hook slide fixation point. Each single ear hook slide fixation point is provided with a hook. The lower end of each hook is provided with a pulley which is used for carrying an additional line. The connection pieces, the aluminum alloy supporting tubes, the ear hook slide fixation points, the hooks and the pulleys are respectively divided into two kinds and are symmetrically arranged around the additional line shoulder frame. A middle pulley which is used for lifting the additional line is arranged below additional line shoulder frame connection. The additional line homing balance supporting device provided by the utility model has the advantages that the quality of additional line homing is improved; material waste is avoided; a construction process is simplified; the construction efficiency is improved; and manpower is saved.
Description
Technical field
The utility model belongs to rail traction contact net for power supplying construction tool technical field, the additional wire playback balanced support device that uses when being specially the playback of passenger dedicated railway line positive feeder.
Background technology
In high-speed rail construction in recent years, because the special positive feeder of visitor adopts pre-twisted protective more, preformed armor rods is long, twines difficulty in the air at height, therefore mostly adopts and carries out mark in the air at height, twine in the bottom, and then the way of top playback.
1, traditional way, workload is large, and efficient, quality are all not high.
1. easily skew after the conventional approach playback; cause the additional wire suspension insulator can not be perpendicular to ground, often doing over again can solve several times, and pre-twisted protective can only utilize at most three times; and twine and remove all cumbersome, and remove and not in placely be easy to cause ceiling to scrap.
2. traditional way is difficult to take into account the degree of speeding of additional wire.In conventional approach, carry out mark in additional wire, just determined the position in the preformed armor rods, can't observe the sag in whole relevant the striding, the interior sag of each span is uneven later on to cause operation.
Therefore: the playback of additional wire is considered to be a loaded down with trivial details operation always in the contact network construction process.
2, compare labor intensive.In traditional way, need upper operating 1-2 people, bottom stay cord 1 people, on-the-spot monitoring 1 people.
The utility model content
The technical problem of this novel solution is to provide a kind of aid for carrying operating efficiency and security and stability in the above-mentioned operation process, i.e. additional wire playback balanced support device.
For solving the problems of the technologies described above the technical solution adopted in the utility model be:
Additional wire playback balanced support device, the middle part connector that bag is connected with additional wire shoulder frame by the middle part connecting bolt, an end of connecting aluminum alloy stay pipe on the connector of middle part, the aluminium alloy stay pipe other end arranges the sliding fixing point of monaural hook, on the sliding fixing point of monaural hook hook is set, the hook lower end is provided for carrying the pulley of additional wire.
Described connector, aluminium alloy stay pipe, the sliding fixing point of monaural hook, hook and pulley are respectively two kinds, are symmetrical arranged with additional wire shoulder frame.
The below that is positioned at the connection of additional wire shoulder frame is provided for promoting the middle part pulley of additional wire.
Good effect of the present utility model is:
1, improves additional wire playback quality.The use of additional wire playback eyelid retractor has changed the method that playback is twined in traditional bottom, adopts the playback of direct top, the skew of additional wire insulator and suspension clamp skew have been avoided, and the top personnel can be convenient for measuring the sag of additional wire after eyelid retractor sets, adjust.Greatly improve the accuracy of additional wire sag, guaranteed construction quality.
2, avoid waste of material.The use of additional wire playback eyelid retractor, the secondary of having avoided old method for homing to cause is torn open and is twined preformed armor rods, has effectively stopped waste of material.
3, simplified work progress, improved efficiency of construction, saved manpower.Because the use of additional wire playback eyelid retractor, install so that the operation of originally carrying out in the bottom all changes top into, saved additional wire is relay down two work progress with pull-up, improved efficiency of construction, make the construction operation group that originally needs 3-4 people, changing 2 people into can finish.Increase work efficiency more than 50%.
Description of drawings
Fig. 1: the additional wire playback supports front schematic view
Among the figure: 1, hook 2, middle part pulley 3, pulley 4, the sliding fixing point 5 of monaural hook, aluminium alloy stay pipe 6, middle part connector 7, middle part connecting bolt.
Embodiment
Additional wire playback balanced support device as schematically shown in Figure 1, the middle part connector 6 that bag is connected with additional wire shoulder frame by middle part connecting bolt 7, an end of connecting aluminum alloy stay pipe 5 on the connector 6 of middle part, aluminium alloy stay pipe 5 other ends arrange the sliding fixing point 4 of monaural hook, on the sliding fixing point 4 of monaural hook hook 1 is set, links up with the pulley 3 that 1 lower end is provided for carrying additional wire.Described connector 6, aluminium alloy stay pipe 5, the sliding fixing point 4 of monaural hook, hook 1 and pulley 3 are respectively two kinds, are symmetrical arranged with additional wire shoulder frame.The below that is positioned at the connection of additional wire shoulder frame is provided for promoting the middle part pulley 2 of additional wire.
During construction eyelid retractor is launched to be installed in additional wire and take on correct position on the frame, fastening good middle part connecting bolt.Then the hook bar that will make is hung on the sliding fixing point of two end hooks, hangs up properly pulley in the hook lower end.The additional wire that needs playback after setting up is placed in the pulley of two hook bar bottoms.Behind the stabilizer wire, begin to twine preformed armor rods.After the preformed armor rods winding is finished, in the pulley of additional wire as for middle part hook cunning, then lift the connection cord on pulley top, additional wire is lifted the porcelain vase place that hangs to the additional wire stringing, be connected the additional wire suspension clamp fastening with porcelain vase.After finishing, remove additional wire playback balanced support device.
The above is embodiment of the present utility model only, is not limited to utility model patent, and for a person skilled in the art, the utility model can have various modifications and variations.All within the spirit and principle of utility model, any modification of doing, be equal to replacement, improvement etc., all should be included within the claim scope of utility model.
