Abstract
The invention discloses a height-adjustable transporting ladder, wherein the bottom part of the transporting ladder is fixed on the ground; the top part of the transporting ladder extends to an inlet of a furnace body; two sides of the transporting ladder are respectively provided with a trolley running rail; the lower part of the transporting ladder is fixed on the ground through a plurality of supporting brackets which are arranged at equal intervals; each of the supporting brackets comprises two supporting legs; the two supporting legs of each supporting bracket are composed of an inner supporting leg and an outer supporting leg; one end of each inner supporting leg is movably arranged in the corresponding outer supporting leg; the inner supporting legs and the outer supporting legs are fixed through fixing elements. The height-adjustable transporting ladder can be adapted to furnace bodies with different heights, and has the advantages of simple structure, low cost and wide application range; the transporting ladder needs not to be installed on the ground every time, so that the time and labor are saved.
Description
Technical field
The present invention relates to a kind of load transfer device, particularly a kind of adjustable for height transport ladder.
Background technology
At present, when ores lifting to desulfuring furnace is carried out desulfurization preheating, normally ore is put into transport trolley, be transported in the desulfuring furnace of certain altitude by transporting ladder, but existing transport ladder is fixed on after on ground, its support is fixing, height can not be carried out regulate, for the desulfuring furnace of differing heights, the transport ladder of differing heights need be selected, also need again transport ladder to be mounted on ground, not only trouble is installed, waste time and energy, go back cost of idleness, use very inconvenience.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art and provide a kind of time saving and energy saving, cost-saving adjustable for height transport is terraced.
Technical scheme of the present invention is: a kind of adjustable for height transport ladder, the bottom of described transport ladder is fixed on ground, top extends to the inflow point of body of heater, the both sides of transporting ladder are provided with trolley travelling track, the bracing frame that the below of transporting ladder is equidistantly arranged by several is fixed on ground, and support frame as described above comprises two supporting legs; Described supporting leg is made up of interior supporting leg and outer supporting leg, and one end of described interior supporting leg is located in outer supporting leg movably, is fixed between interior supporting leg and outer supporting leg by connecting element.
Further, described connecting element comprises at least two fixed orifices and the bolt assembly be fixed on described fixed orifice or supporting pin that at least one fixed orifice that outer supporting leg is axially arranged with, interior supporting leg are axially arranged with.
Further, 3 ~ 5cm is spaced apart between adjacent two of the fixed orifice described interior supporting leg is axially arranged with.
Further, the outside face of described interior supporting leg is provided with scale.
Further, the downside of described interior supporting leg is provided with outside thread, and the upside of outer supporting leg is provided with the matched negative thread with outside thread, and connecting element is setting nut, and the inner side of setting nut is provided with the matched negative thread with outside thread.
Further, reinforced rib is provided with between described two supporting legs.
Further, the angle between described transport ladder and ground is 30 ° ~ 75 °.
Further, the below of described transport ladder is provided with four bracing frames, and the distance often between adjacent two bracing frames is 70 ~ 120cm.
The present invention compared with prior art has following features: transport that design height is adjustable flexibly ladder, is applicable to the body of heater of differing heights, and structure is simple, and cost is low, applied widely, and need not all installation and transportation ladder is on ground at every turn, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention;
Fig. 2 is the structure enlarged diagram of bracing frame embodiment illustrated in fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed construction of the present invention is further described.
Embodiment 1
As depicted in figs. 1 and 2: a kind of adjustable for height transport ladder, the bottom of transport ladder 1 is fixed on ground, and top extends to the inflow point of body of heater, and the angle between transport ladder 1 and ground is 45 °; The both sides of transporting ladder 1 are provided with trolley travelling track 2, and the below of transporting ladder 1 is fixed on ground by four bracing frames 3, and the distance often between adjacent two bracing frames 3 is 100cm.Bracing frame 3 comprises two supporting legs, is provided with reinforced rib between two supporting legs; Supporting leg is made up of interior supporting leg 4 and outer supporting leg 5, and one end of interior supporting leg 4 is located in outer supporting leg 5 movably, is fixed between interior supporting leg 4 and outer supporting leg 5 by connecting element.
Particularly, the fixed orifice 51 that outer supporting leg 5 is axially arranged with, interior supporting leg 4 is axially arranged with six fixed orifices 51,5cm often between adjacent two fixed orifices 51, fixed orifice 51 on outer supporting leg 5 and being fixed by bolt assembly 52 between the fixed orifice 51 on interior supporting leg 4, bolt assembly 52 can coordinate with the arbitrary fixed orifice 51 on interior supporting leg 4 through the fixed orifice 51 on outer supporting leg 5, thus is fixed with interior supporting leg 4 by outer supporting leg 5.The outside face of interior supporting leg 4 is provided with scale 6, handled easily personal observations thus determine height, make regulate more flexible, facilitate.
During use, operating personal first loosers a bolt assembly 52, bolt assembly 52 is departed from the fixed orifice 51 on interior supporting leg 4, move up and down interior supporting leg 4, by observing scale 6, according to position and the height of body of heater, transport ladder 1 is adjusted to required height, bolt assembly 52 aims at the fixed orifice 51 in this height on supporting leg 4, is tightened.Because the fixed orifice 51 on interior supporting leg 4 is constant spacing, required height is not necessarily provided with fixed orifice 51, therefore, nearest fixed orifice 51 can only be got to reduce error.
Embodiment 2
As shown in Figure 2: be with the difference of embodiment 1, the downside of interior supporting leg 4 is provided with outside thread, and the upside of outer supporting leg 5 is provided with the matched negative thread with outside thread, and connecting element is setting nut, and the inner side of setting nut is provided with the matched negative thread with outside thread.
During use, in moving by supporting leg 5 is interior outside, supporting leg 4 is adjusted to required height, after having confirmed height, interior supporting leg 4 is rotatably connected in the inner side of outer supporting leg 5, and is tightened by setting nut.Wherein, interior supporting leg 4 is when differing heights screws, and the outside thread on interior supporting leg 4 is exposed one section all the time, screws for setting nut.
Because the leg structure in the present embodiment one of ordinary skill in the art will appreciate that, so do not represent with other accompanying drawing again.
