The integral dropper auxiliary adjusting device disclosed by the utility model has the advantages of simple structure, convenience for operation, simplicity and convenience for adjustment, capability of continuously adjusting data, small errors, high precision and high safety; and the personal safety of personnel in a working process is ensured, and the working efficiency is improved.
Description
Technical field
The utility model relates to a kind of special line for passenger trains contact net integrated dropper auxiliary conditioning unit.
Background technology
The technical standard that the Beijing-Tianjin inter-city railway contact system is led high aspect is: height of contact wire be the 5300mm(error be ± 20mm), the maximum height difference of two adjacent hitch poinies is 10mm, grade of contact wire≤0.05%.Traditional dropper method for prefabricating, 1. 2. measurement is removed 3. prefabricated 4. adjustment and is 5. measured 7. repetition measurement of 6. crimping, and this kind homework precision requires high, work capacity is large, cause work heavy, main time loss is regulated number of times in the control process of dropper more, has restricted the repair schedule in work area.The aloft work personnel without object of reference, can only regulate with subjective and experience in operating process, and error is larger.
The utility model content
The technical problems to be solved in the utility model provides a kind of special line for passenger trains contact net integrated dropper auxiliary conditioning unit, and it has adjusts to the right place dropper length is disposable, and shortening the time that the adjusting stage consumes is target.The fine tuning precision of having determined dropper is high, and the making error is little, guarantees that the applied to high-speed railway touching net gradient meets the characteristics of technical requirements.
For solving the problems of the technologies described above the technical solution adopted in the utility model be:
Special line for passenger trains contact net integrated dropper auxiliary conditioning unit, comprise the S hook (1), variable dropper line (2), fine setting instrument (3), quantitative dropper line (4) and the contact wire hanger ear (5) that connect in turn, described S hook (1) carries out crimping by dropper crimp, heart type ring, the connection that heart type ring set carries out at the S hook with the two ends that are connected to variable dropper line (2) of variable dropper line (2).
Described fine setting instrument (3) two ends arrange has the opening coupling end and the coupling end of remaining silent, and described variable dropper (2) is connected with the opening coupling end of fine setting instrument (3).
The coupling end and quantitatively be connected to direct crimping between the dropper (4) of remaining silent of described fine setting instrument (3), quantitatively dropper (4) other end is connected with contact wire hanger ear (5).
Described fine setting instrument (3) is the open auger buckle structure, the opening coupling end is split bolt, the coupling end of remaining silent is the bolt of remaining silent, trimming scale (31) is set on the fine setting instrument (3), the length of regulating monolithic controller in the advance and retreat of fine setting instrument (3) by bolt, and then the length of definite whole object dropper.
For preventing not planning a successor in the adjustment process, should there be certain coincidence therefore determine adjacent variable adjustment.With reference to following table:
Variable dropper setting range synopsis
Install for convenient, save time, raise the efficiency, guarantee safety, adopt the S hook to be connected with the catenary connecting bridge, conductor part continues to adopt contact wire hanger ear to connect.
The utility model has the advantages that: the utility model is simple in structure, easy to operate, adjustment is simple and convenient, can regulate continuously on the data, and error is little, and precision is high, and is safe.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 dropper auxiliary conditioning unit structural representation
Fig. 2 finely tunes the tool construction schematic diagram.
The specific embodiment
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
The special line for passenger trains contact net integrated dropper auxiliary conditioning unit of anticipating as shown in Figure 1 and Figure 2, comprise the S hook 1, variable dropper line 2, fine setting instrument 3, quantitative dropper line 4 and the contact wire hanger ear 5 that connect in turn, described S hook 1 carries out crimping by dropper crimp, heart type ring, the connection that heart type ring set carries out at the S hook with the two ends that are connected to variable dropper line 2 of variable dropper line 2.
Described fine setting instrument 3 two ends arrange has the opening coupling end and the coupling end of remaining silent, and described variable dropper 2 is connected with the opening coupling end of fine setting instrument 3.
The coupling end and quantitatively be connected to direct crimping between the dropper 4 of remaining silent of described fine setting instrument 3, quantitatively dropper 4 other ends are connected with contact wire hanger ear 5.
Described fine setting instrument 3 is the open auger buckle structure, the opening coupling end is split bolt, and the coupling end of remaining silent is the bolt of remaining silent, and trimming scale 31 is set on the fine setting instrument 3, regulate the length of monolithic controller in the advance and retreat of fine setting instrument 3 by bolt, and then the length of definite whole object dropper.
This practical dropper auxiliary conditioning unit is by adopting common dropper line to pass through the two ends crimping as main link, and be marked with the dropper length range that the variable dropper is applicable to regulate at the variable dropper, scale on the fine tuning instrument is used for showing its fine tuning variable quantity, and open auger is buckled and adopted the waste material of removing on the section insulator; Top connects the S hook of making by waste steel bar and connects, and the bottom adopts contact wire hanger ear to form.Whole minute five parts, five parts can be passed through the attaching parts assembly and disassembly.Make a dropper auxiliary conditioning unit by this scheme, try out at dimension eternally happy station, the pipeline section eternally happy work area of Beijing-Tianjin segmentation, Beijing.Draw conclusion on probation after one month trial period: this dropper auxiliary conditioning unit, simple in structure, easy to operate, adjust simple and conveniently, can regulate continuously on the data, error is little, and precision is high, and is safe.By using the dropper auxiliary conditioning unit, the error in length of precast monolithic dropper is reduced to 3.7mm by original 11.17mm, on average changes the time spent of every dropper by 22 minutes original/root, is reduced to 10 minutes/root.
