Abstract
The utility model relates to a hanging string adjustable device. An adjustable device is connected between a fixed hanging string and a movable hanging string, and the adjustable device is composed of an adjusting seat, an adjusting bolt and a fixed screw cap. The device has simple structure, convenient adjustment and higher adjustment accuracy; the contact system of the existing electrified railroad is not need to add any auxiliary equipment. On the premise without increasing the investment of the power system, the utility model can increase the running speed, lighten the labor intensity of the workers and improve the labor efficiency, and therefore, the utility model is the special technology for the contact system and is worth popularizing and applying.
Description
The utility model relates to a kind of Trolley lines adjusting device, is mainly used in electrification railway contact net.
Railway contact line is the facility of power supply power locomotive electric energy.Its contact wire is on the column that sets up in orbit, and the lead between column and the column is because deadweight must have sag.If the speed of a motor vehicle is lower, (speed of a motor vehicle is less than 70 kilometers/hour) can adopt the pulling force that suitably increases the lead two ends by tightening device to reduce the tramway type suspension equip ment of the band compensation of lead sag.The speed of a motor vehicle is high slightly, and tramway type suspension equip ment can not satisfy the needs that locomotive is got stream, must increase the full compensation stitched catenary equipment of equipment such as catenary, dropper on the basis of tramway type suspension equip ment.
Problem is just on dropper.The effect of dropper is to connect catenary and lead (just lead is suspended on the catenary), lead is kept as far as possible and the parallelism longitudinally of rail face.Get stream smoothly to guarantee operating electric locomotive.Because it is that root comes and go beformable body (as different expanding with heat and contract with cold in season that lead is subjected to a plurality of external force effects, the increase and decrease of top piece number etc. is weighed down in the compensation of tightening device), parallel between lead and rail level will random fluctuation so, and maintenance gang for catenary must establishment officer keep in repair and adjust.
The adjustment of dropper length, operating sequence is at present: the workman stands on the special-purpose tower wagon and carries out operation, earlier must be straight the exhibition of taking apart of the knot of the iron wire on wire clamp, by the spacing location of given data and mensuration, examination is transferred, and is unfixing.Like this, one one dropper is debugged one by one, treat check proofread and correct errorless after, just iron wire is wound the knotting location, even adjust location or inaccuracy like this, lead and the permission of rail level interval error are at ± 30 millimeters.
The purpose of this utility model is: design a kind of Trolley lines adjusting device, it is simple in structure, easy to adjust, and the accuracy rate of adjustment is higher.
Design philosophy of the present utility model:
Development along with China's electrified railway, the raising of the speed of a motor vehicle, the quality of asking for current wire is also corresponding will get well, that is to say each dropper point leave the right or normal track the interval error of face can not allow again ± 30 millimeters, but it is littler, so, be badly in need of a kind of simple in structure, higher adjustable dropper device meet requirements of adjustment accuracy rate of design.
The utility model design plan: a kind of Trolley lines adjusting device, comprise fixedly dropper (5) and movable dropper (3), fixedly dropper (5) and movable dropper (3) link together fixedly being provided with tunable arrangement (4) between dropper (5) and the movable dropper (3), tunable arrangement (4) is by adjustment seat (8), regulating bolt (9) and hold-doun nut (10) constitutes, adjustment seat (8) vertically is shaped on through hole (11), laterally be shaped on stepped appearance through hole (12), and two holes connect mutually, be shaped on through hole (13) on the bolt cap of adjusting bolt (9), the adjustment seat (8) that is arranged on adjusting bolt (9) goes up in the horizontal stepped appearance through hole (12), and screw rod stretches out outside the hole, be with ring washer on it, spring washer and hold-doun nut (10), and make the through hole (13) on its bolt cap corresponding with the longitudinal hole (11) on the adjustment seat (8), fixedly dropper (5) upper end is fixed on the lower end of adjustment seat (8), and movable dropper (3) lower end adjust bar (14) passes through hole (11) and (13) and is fixed by adjusting bolt (9) and hold-doun nut (10) and in position goes up.Adjustment seat (8) external wall of upper portion is the regular hexagon cylinder, and the bottom is shaped on boss and is used to weld fixedly dropper (5) upper end.
The utility model compared with prior art, the one, accuracy rate simple in structure, easy to adjust, that adjust is higher; The 2nd, easily manufactured, cost is low, and change over mutually around connecting mode, overall weight can not increase; The 3rd, its application can make existing contact system not increase any attendant equipment, under the prerequisite of the system that do not increase electric power investment, improve road speed, shorten time of run, increase railway operating income, simultaneously can alleviate working strength of workers, raise labour efficiency, be a contact system special technology that is worthy of popularization.

Fig. 2 is the utility model adjustment seat birds-eye view.
Fig. 3 is the A-A cutaway view of Fig. 2.
Fig. 4 is the utility model tunable arrangement structure cutaway view.
Fig. 1,2,3,4, and specification sheets the 5th part has been described a kind of embodiment of the present utility model, during use, movable dropper (3) upper end is linked to each other with catenary (1) by wire clamp (2), fixedly dropper (5) lower end links to each other and can use with contact wire (7) by wire clamp (6), the spacing location examination that connects given data and mensuration in the operation is earlier transferred, being about to hold-doun nut (10) unclamps, the adjust bar (14) that movable dropper (3) lower end is passed adjustment seat (8) puts in or withdraws from a small amount of part, again that hold-doun nut (10) is fixing gently, such one one dropper is debugged one by one, after treating that the check correction is errorless, again hold-doun nut (10) is tightened fixation one by one and get final product.Adjustment seat (8) external wall of upper portion is the regular hexagon cylinder, after being fixed with wrench, is convenient in adjustment hold-doun nut (10) be unclamped and tighten, and the bottom is shaped on boss and is used to weld fixedly dropper (5) upper end, makes it to be connected firmly and flat appearance.
