Abstract
The utility model discloses a three-section retractable bracket which comprises carrier rollers and a support beam. The support beam is used for carrying the carrier rollers, is mounted on a bottom support and comprises two lower transverse beams made of rectangular section bars, the lower transverse beams are bent to form two pieces of C-shaped steel in a mirror symmetry manner, and a slide rail is formed between the two pieces of C-shaped steel; the support beam further comprises upper transverse beams, and the upper transverse beams are made of angle steel and are slidably arranged on the slide rail formed between the two pieces of C-shaped steel of the lower transverse beams. The three-section retractable bracket has the advantages that technical means of the grooved retractable bracket are simple, convenient and feasible, the maintenance difficulty can be relieved, carrier roller replacement time can be shortened, conveyor belts do not need to be hoisted by a crane, maintenance staffs can easily replace the replaceable carrier rollers without entering a framework, and accordingly the work efficiency and the personal safety of the maintenance staffs can be greatly improved.
Description
Technical field
The utility model relates to belt material transfer equipment, relates in particular to a kind of grooved telescopic bracket.
Background technology
Traditional fixed belt conveyer, be all generally carry large part material, so volume greatly, parts weight.Structurally they also have varied, merits and demerits is also different, but they all exist a common shortcoming to be, such as the support beam for carrying idler, base plate, B-C post, quarter line pillaring, frame etc., all integrally welded, without dismounting and Telescopic.
This integrally welded, without the fixed belt conveyer of dismounting and Telescopic, cause obstacle to maintenance, maintenance in the future, as changed the carrying roller of corrupted, need to realize adopting loop wheel machine that load-transfer device is sling, maintainer's access mechanism inside, carrying roller can be taken out, the difficulty of changing is large, and work consuming is consuming time, and maintenance cost is high.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to maintenance, syllogic concertina type bracket is efficiently provided.And have locating dowel pin, and be located by connecting firmly, be not easy to become flexible.
The utility model is achieved through the following technical solutions:
A kind of syllogic concertina type bracket, comprise carrying roller 6 and the support beam 1 for carrying idler 6, it is upper that described support beam 1 is arranged on the bearing 1-2 of bottom, and described support beam 1 is the cross sill 1-1 that is mirror image symmetry and is bent into C shape steel by two rectangle section bars, between two C shape steel, forms slide rail;
Described support beam 1 also comprises the entablatrance 1-3 being made by angle steel, and entablatrance 1-3 is arranged on the slide rail forming between two C shape steel of cross sill 1-1 in the mode of sliding;
Described carrying roller 6 is arranged on entablatrance 1-3 by support.
Described entablatrance 1-3 is divided into three sections, and the structure of every section is identical;
Described support comprises two limit supports and a central support, is divided into limit support 2 and central support 3; Joint between described central support 3 and limit support 2 is provided with locating dowel pin 4.
Described carrying roller 6 is divided into side roller 6-1,6-3 and middle carrying roller 6-2, and corresponding limit support 2 and the central support 3 of passing through is arranged on each section of entablatrance 1-3.
Described limit support 2 and central support 3 are fixed by bolt 5 and two C shape steel of cross sill 1-1 respectively.
Described limit support 2 also comprises the side plate 2-1 that props up side roller 6-1,6-3.
Described side plate is fixed by bolt 5-1 and bearing 1-2.
With respect to prior art, the utlity model has following advantage and beneficial effect:
Brief description of the drawings
Fig. 1 is the utility model syllogic concertina type carrier structure schematic diagram;
Fig. 2 is Fig. 1 construction profile schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is more specifically described in detail.
As shown in Figure 1, 2.The utility model syllogic concertina type bracket, comprises carrying roller 6 and the support beam 1 for carrying idler 6, and described support beam 1 is arranged on the bearing 1-2 of bottom; Described support beam 1 is mirror image symmetry and is bent into the cross sill 1-1 of C shape steel by two rectangle section bars, between two C shaped steel, form slide rail;
Cross sill 1-1 can adopt common formed channel steel or adopt steel plate to form after bending, and two bending angles are approximately 90 °.
Described support beam 1 also comprises the entablatrance 1-3 by angle steel, and entablatrance 1-3 is arranged between two C shape steel of cross sill 1-1 and forms on slide rail in the mode of sliding; Described carrying roller 6 is arranged on entablatrance 1-3 by support.
Entablatrance 1-3 can adopt cross sectional shape to be the section bar (claim angle bar in industry, bending angle is approximately 90 °) of inverted "L" shaped.
Described entablatrance 1-3 is divided into three sections, and the structure of every section is identical; Described support is divided into limit support 2 and central support 3.
Described carrying roller 6 is divided into side roller 6-1,6-3 and middle carrying roller 6-2, and corresponding limit support 2 and the central support 3 of passing through is arranged on each section of entablatrance 1-3.
Joint between described central support 3 and limit support 2 is provided with locating dowel pin 4.
Described limit support 2 and central support 3 are fixed by bolt 5 and two C shaped steel of cross sill 1-1 respectively.
Described limit support 2 also comprises the side plate 2-1 that props up side roller 6-1,6-3.
Described side plate is fixed by bolt 5-1 and bearing 1-2.
In the time that carrying roller 6 damages need to be changed, after bolt of rear end plate 5 on support (comprising limit support 2 and central support 3) is unclamped, need to change respectively the limit support 2 (or central support 3) of carrying roller 6 along entablatrance 1-3 axial direction and haul out, be i.e. replaceable carrying roller 6.
After carrying roller 6 is changed, along entablatrance 1-3, limit support 2 (or central support 3) is pushed successively and is connected location with locating dowel pin 4, finally bolt 5-1 is tightened.
Grooved telescopic bracket of the present utility model, technological means is simple and easy to do, alleviate maintenance difficulty and reduced the time of changing carrying roller, without the load-transfer device of slinging with loop wheel machine, maintainer just can change replaceable carrying roller easily without entering in frame, has greatly improved work efficiency and maintainer's personal safety.
