Abstract

The utility model relates to a shaped steel cable bridge frame, which overcomes the problems existing in the prior art that the upright post and the supporting arm of the cable bridge frame are mainly made of standard steel and is large in the consumption of the steel, low in the structural strength and large in the distance of the layers. The utility model is characterized in that the upright post and the supporting arm are made of square shaped steel which is provided with an opening slide way with the single side, a tailor-made screw nut connected with a screw for fixing the supporting arm corresponds to the upright post and the slide way, and a screw nut is installed between the tailor-made screw nut and the bottom wall of the upright post. The utility model has the advantages of simple structure, discretional adjustment of the distance of the layers and the position of the bridge frame positioned on the supporting arm, high structural strength, small size and light weight. The utility model is suitable for each department such as the chemical industry, the petroleum, the electric power, the communication, the metallurgy, the mine, etc.

Description

Shaped steel cable bridge frame

The utility model relates to a kind of deformed steel cable testing bridge that is suitable for power cable, actuating cable, laying of communication cable and uses.

Cable testing bridge is widely used in each departments such as chemical industry, oil, electric power, communication, metallurgy, mine; But the column of cable testing bridge of the prior art and the structure of trailing arm mainly adopt the Standard Steel Section manufacturing, and its column includes I-steel, channel-section steel and angle steel column; Its trailing arm mostly is angle steel or iron plate is enclosed the trailing arm of system; The steel consumption amount of the column of this spline structure and trailing arm is very big; In addition,, on column, be processed with several holes that is fixedly connected,, on column, also be processed with several connecting hole for fixing ladder on trailing arm in order to regulate the upper and lower position of trailing arm on column; But connecting hole on the column and the connecting hole on the trailing arm can not be determined the position again in advance, so need in some holes of multi-processing on the column and on the trailing arm, so that adjust when installing, certainly will alleviate the intensity of shaped steel so again, and do not reach the purpose of stepless adjustment position in the as installed, install very inconvenient; In addition, trailing arm of the prior art is oblique support, limits and has controlled the cable testing bridge interfloor distance and must not bring certain difficulty more for narrow and small position, mounting point less than 250 millimeters.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of and can not use Standard Steel Section fully, thereby the saving steel, and and then reach the raising structural strength, again can stepless adjustment position in installation and can dwindle the deformed steel cable testing bridge of installing space.

The utility model is achieved in that

It includes column, by fixed plate and screw be fixedly connected on column trailing arm and be connected in the ladder of forming by terraced limit and step on the trailing arm by pressing plate and screw, said column or trailing arm or column and trailing arm are the square deformed steel that has monolateral open slideway, trailing arm then can stand its upper and lower position of stepless adjustment on the open slideway of leaning on, to determine interfloor distance according to actual needs, use screw fastening then, but ladder also its position of step-less adjustment on the open slideway of trailing arm is to be fit to the needs of as installed.

Advantage of the present utility model is:

1, the column of the utility model structure and trailing arm adopt the square profiled bar manufacturing that has monolateral open slideway, can not use Standard Steel Section fully, and the consumption of steel can be saved steel 30～50% than the Standard Steel Section cable testing bridge; And, many kinds (angle steel, channel-section steel, I-steel etc.) of also having got rid of existing cable testing bridge Standard Steel Section, many specifications (50,60,70,80,100,120 ...) complexity, realized the monotony of element, improved interchangeability, this has also brought very big convenience for the replacing of construction.

2, the utility model is simple in structure, the interfloor distance of crane span structure arbitrarily (stepless) adjust and modularity good, so that the job site is installed, adjusted is extremely convenient, positive meaning is also arranged to speeding up the work and shortening the construction period.

3, owing to adopt the square special-shaped column of monolateral open slideway, need on column, not reprocess connecting hole, neither need punching to fix, so deformed steel cable testing bridge intensity height can replace 10 ^#I-steel and 10 ^#Channel-section steel, and volume is little, and in light weight, beautiful shape.

5, in addition, the utility model has changed existing cable testing bridge because trailing arm is oblique support, restriction and actuating cable crane span structure interfloor distance must not be less than 250 millimeters problems, adopt cable testing bridge interfloor distance of the present utility model can dwindle at 150～60 millimeters, this is for narrow and small position, mounting point, played the effect of dwindling installing space, be existing cable testing bridge can not replace.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As Fig. 1, Fig. 2 and shown in Figure 6, the utility model has a column 1, by be fixedly connected trailing arm 2 on column 1 of fixed plate 3 and screw 4, by be fixedly connected the ladder of forming by terraced limit 5 and step 6 on trailing arm 2 of pressing plate and screw 7, said column 1 is for having the square deformed steel of monolateral open slideway, the outer rim of its cross section is square, it is of a size of 30 * 30～60 * 60(millimeter), inside is square empty stomach, there is an opening at middle part on an one limit, each inside curved straight flange of 90 ° that has of opening both sides forms a slideway naturally; Corresponding to the slideway of column 1 have one with the fixing screw 4 joining special nuts 9 of trailing arm 2, between special nut 9 and column 1 diapire nut spring 10 is installed; Said special nut 9 as shown in Figure 5, its side is processed with and is used for the spring seat 9b of mounting spring 10; Opposite side is processed with and is used for and the screw 4 joining diameters internal thread 9c more smaller than spring seat 9b, and in the both sides of symmetrical center line, is processed with a pair of groove 9a corresponding to the slideway of column 1; Said trailing arm 2 as shown in Figure 4, it and column 1 adopt identical shaped square deformed steel, end at square deformed steel is welded with trailing arm fixed plate 3, promptly be coupled to each other fixing between trailing arm 2 and the column 1 by special nut 9 interior on an empty stomach in these fixed plate 3 usefulness screws 4 and the column 1, in the as installed, unclamp screw 4, power by spring 10, special nut 9 can be withstood on the slideway of column 1, pressure spring 10, can make the special nut 9 and the slideway of column 1 that certain interval is arranged, can adjust special nut 9 on the slideway, upper/lower positions, fixed plate 3 with trailing arm 2 is connected and fixed with special nut 9 by screw 4 packing rings 8 again, has realized that promptly trailing arm 2 is on column 1, the adjustment of upper/lower positions.In the practice of construction engineering, the ladder of being made up of terraced limit 5 and step 6 can be forms such as curved logical, the horizontal threeway of straight-through type and level, horizontal four-way, between the trapezoidal crane span structure and trapezoidal crane span structure with curvedly lead to, connect being connected between the threeway, four-way with connecting sheet; If step 6 is replaced by base plate, promptly form the remittance wire casing, can form straight-through, curved logical, threeway, four-way too, structure of the present utility model adapts to above-mentioned various forms of ladder and converges wire casing, also can be single or multiple lift, if multilayer, its interfloor distance can be contracted to 200～100 millimeters for the remittance wire casing; Then can dwindle so far 150～60 millimeters for ladder.
