The adjustable position limiting positioning support seat has the advantages that through the regulation of the position limiting block, the control on the lifting quantity of a positioning device is realized, and the technical problem that the distance between a contact line and a positioning pipe in the in-site construction cannot meet the design requirement, so that the lifting quantity of the positioning device is insufficient or the lifting altitude is too high can be solved.
Description
Technical field
The invention belongs to electrification railway contact net part technical field, be specifically related to a kind of adjustable spacing positioning support.
Background technology
In electrification railway contact net, registration device is divided into spacing positioning apparatus and non-spacing positioning apparatus, and in configuration, more than 90% is spacing positioning apparatus.Spacing in device refers to that the lifting of steady arm is spacing, and its effect mainly prevents while pantograph lifting needs to make bow and steady arm collides registration arm accident meeting in locomotive traveling process.
For integral cantilever structure, contact wire is definite value apart from the designed distance between registration arm, and being generally is 500 ± 20mm (see Fig. 1), and the Uplifting amount of steady arm is spacing is also definite value, is generally 180 ± 20mm (see Fig. 2).Stop gear is arranged on positioning support, is non-adjustable structure limiting stopper.
Because integral cantilever does not possess modulability substantially, often overlap bracket, the specification of registration arm is all calculated by the concrete installation parameter of correspondence, that one_to_one corresponding is installed and used with pillar, therefore a whole set of bracket system is difficult to after installing ensure that the distance between contact wire and registration arm meets 500 ± 20mm requirement, after usual installation, contact wire can reach 500 ± 50mm apart from the distance between registration arm, have even to exceed specified value more.And the design basis data of steady arm and positioning support is: when contact wire and registration arm spacing are 500mm ± 20, the Uplifting amount of steady arm is spacing is 180 ± 20mm.If scene occurs that contact wire is 420mm situation apart from the distance between registration arm, mean that the Uplifting amount of steady arm is occupied 80mm in advance, pantograph will limit by limited positioning support through out-of-date uplift of steady arm 100mm, if this Uplifting amount does not meet the actual Uplifting amount of contact wire when motor supply shop enters, just there will be hard spot to impact, adverse consequences is caused to pantograph, contact wire, steady arm, brings traffic safety hidden danger.Limited location positioning support stop gear is fixed, causes uplift of steady arm amount to be also fixing, cannot regulate, and certainly also cannot compensate or the Uplifting amount of compression set device.
Summary of the invention
The technical matters that the present invention solves: a kind of adjustable spacing positioning support of design, limiting stopper in former spacing positioning support is changed into adjustable, by the adjustment of limiting stopper, realize control to uplift of steady arm amount, the uplift of steady arm quantity not sufficient that the spacing solving contact wire and registration arm in site operation can not meet design requirement and cause or the too high technical matters of lifting.
Technical solution of the present invention: a kind of adjustable spacing positioning support, comprise body, the inverted "L" shaped plate that described body is be arranged in parallel by two panels is formed by connecting by connecting panel, and the upper end of two panels inverted "L" shaped plate is fixed with anchor ear, tie bolt is equipped with in lower end, described two panels inverted "L" shaped plate lower end is fixed with fixed block between bending place, and fixed block is positioned on described bending place; Described fixed block has inner bolt hole, in inner bolt hole, adjusting bolt is housed; Described adjusting bolt is set with jam nut, and jam nut is positioned on the upper surface of fixed block; The lower end of described adjusting bolt is fixedly connected with limiting stopper, and limiting stopper protrudes the upper arm lower surface of inverted "L" shaped plate.
Described limiting stopper is fastened on the lower end of adjusting bolt by set pin.
The advantage that the present invention compared with prior art has and effect: by regulating the position of limiting stopper, achieve compensation or the compression of uplift of steady arm amount, its lifting value is met design requirement, guarantees pantograph and contact wire good contact, avoid the generation contacting hard spot, ensure traffic safety.

Detailed description of the invention
1-6 describes the specific embodiment of the present invention in detail by reference to the accompanying drawings.
A kind of adjustable spacing positioning support, comprise body 1, the inverted "L" shaped plate 3 that described body 1 is be arranged in parallel by two panels is formed by connecting by connecting panel 4, and the upper end of two panels inverted "L" shaped plate 3 is fixed with anchor ear 2, and tie bolt 5 is equipped with in lower end.Described two panels inverted "L" shaped plate 3 lower end is welded with fixed block 6 between bending place, and fixed block 6 is positioned at described bending place; Described fixed block 6 has inner bolt hole 7, in inner bolt hole 7, adjusting bolt is housed, and adjusting bolt 8 is substantially vertical with the upper arm of inverted "L" shaped plate 3; Described adjusting bolt 8 is set with jam nut 9, and jam nut 9 is positioned on the upper surface of fixed block 6; The lower end of described adjusting bolt 8 is fixedly connected with limiting stopper 10 by set pin 11, and limiting stopper 10 protrudes the upper arm lower surface of inverted "L" shaped plate 3.
The limiting stopper that former spacing positioning support is welded and fixed is improved to adjustable limit block by the present invention.By rotating adjusting bolt 8, adjusting bolt 8 moves up and down in fixed block 6, and the limiting stopper 10 driving its lower end to be connected and fixed moves together, realizes the adjustment of limiting stopper 10 position, thus realizes the control to steady arm 13 Uplifting amount.By jam nut 9, adjusting bolt 8 is locked after adjusting, prevent the change of limiting stopper 10 position.
By anchor ear 2, body 1 is fixed on the registration arm 12 of electrification railway contact net cantilever structure during installation, then steady arm 13 is hinged on the lower end of body 1 by tie bolt 5.When contact wire 14 is less than design value apart from the distance between registration arm 12, illustrate that the Uplifting amount of steady arm is compared initial design values and decreased, now by rotating adjusting bolt 8, the limiting stopper 10 driving its lower end to be connected and fixed moves up, increase the Uplifting amount of steady arm 13, make it meet design requirement, avoid occurring contact hard spot.Otherwise, when contact wire 14 is greater than design value apart from the distance between registration arm 12, illustrate that the Uplifting amount of steady arm is compared initial design values and increased, now limiting stopper 10 is driven to move down the Uplifting amount of compression set device by rotating adjusting bolt 8, make it meet design requirement, avoid occurring beating bow or steady arm collision registration arm accident.In a word, ensure that uplift of steady arm amount meets the requirement of design value by adjustable limit block, pantograph is steadily contacted with contact wire, and then also ensure that traffic safety.
