Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail below with reference to the accompanying drawings by way of examples of preferred embodiments. It should be noted, however, that the numerous details set forth in the description are merely for the purpose of providing the reader with a thorough understanding of one or more aspects of the present invention, which may be practiced without these specific details.
Example 1
As shown in fig. 1, a railing convenient to dismouting, including fixing at railing bottom wedge fixed part 1 and setting up draw-in groove 2 on the installation position of installation railing, fixed part 1 and draw-in groove 2 adaptation chucking, the same position is equipped with perforation 3 and mounting 4 on this draw-in groove 2 and the fixed part 1, and this mounting 4 inserts the perforation and runs through fixed part 1 and draw-in groove 2 with the fixed part locking in draw-in groove 2, adopts the mode of voussoir fixation to be convenient for the dismouting, matches easily, easy and simple to handle.
Fixed part 1 and draw-in groove 2 all are hollow wedge, and fixed part 1 and draw-in groove 2's wedge is tangent fixed, fixed part 1 is the split pin, perhaps can be with fixed part 1 and the fixed buckle of draw-in groove 2 for other. The fixing part can be also provided with a transverse sleeve corresponding to the position of the through hole on the clamping groove, and the cotter pin can directly penetrate into the sleeve for fixing when penetrating.
And a bending plate 6 is arranged on the side wall of the mounting part, the bending plate 6 is fixed with the tower crane platform, and the bending plate is positioned on the back surface of the clamping groove on the fixing part of the railing.
The board 6 of bending is the right angle board, and the bottom welded fastening of this right angle board is on tower machine platform, and the board 6 of should bending is the steel sheet, and the board 6 of bending can balance the installation department on the opposition position railing insert behind draw-in groove 2 the power that produces the installation department.
Example 2
A wedge-shaped fixing part 1 is fixedly arranged at the bottom of a railing, a clamping groove 2 is fixedly arranged on an installation part for installing the railing, the fixing part is inserted into the clamping groove 2 to be matched and fixed, through holes are formed in the same positions on the fixing part 1 and the clamping groove 2, the fixing part 1 is inserted into and penetrates through the fixing part and the clamping groove to be fixed, meanwhile, a bending plate is welded on the back surface of the installation part, and a bending plate 6 is welded on a tower crane platform to balance the stress of the clamping groove.
The rail fixing method ensures that the rail is stable and reliable, meets the use requirement of a tower crane, the clamping groove 2 is a hollow wedge with an upper opening and a lower opening, the upper opening of the clamping groove 2 is larger than the lower opening, the upper volume of the fixing part is larger than the lower volume, and the fixing part 1 is an open-ended bolt or a buckle. The wedge block is connected to enlarge the fault-tolerant space of the manufacturing error of the handrail, the processing and manufacturing difficulty is reduced, and the installation convenience is improved.
When the railing is manufactured, the wedge blocks are additionally arranged at the bottom of the railing and are formed by bending steel plates or directly blanking thick plates and are welded to the railing support legs, namely fixing parts. The clamping groove is formed by bending a steel plate, a cotter pin mounting hole is drilled above the clamping groove, and then the clamping groove is welded to a bending plate at the edge of the platform
Wedge fixation is mainly fixed by filling gaps in the structure. As shown in the above figures, because the space in the structure is limited, the space for transverse displacement is gradually reduced along with the downward movement of the movable wedge block, and finally, the right side surface of the movable wedge block is tightly contacted with the left side surface of the fixed wedge block, so that the transverse displacement in the space is completely limited. The larger the contact area between the two is, the more firm the fixation is.
The principle is as above when the railing is installed, after the railing is inserted into the clamping groove, along with the deepening of the wedge block, the fixing part, the bending plate and the clamping groove are mutually extruded to fix the railing, and finally the split pin is inserted to prevent the landing leg from being separated from the clamping groove
For pipe and sheathed tube fixed mode, the voussoir mainly relies on fixed part, voussoir, draw-in groove of railing and the mutual extrusion of the board of bending to fix, and error tolerance when making is bigger. Because the draw-in groove all reserves sufficient fault-tolerant space in horizontal and vertical, even there are errors such as erection space, deformation and straightness that hangs down in draw-in groove and the railing preparation, the railing still can easily insert the draw-in groove and accomplish fixedly. Meanwhile, due to the fact that the installation gap between the original sleeve and the support leg does not exist, the handrail is more stable and firm after being installed and is not prone to shaking. For preventing the railing from deviating from, the opening pin is passed to the draw-in groove top, restricts the motion of railing vertical direction.
Example 3
A handrail connecting method convenient to disassemble and assemble comprises an upper rod body 7, a lower rod body 8 and a connecting block 9, wherein a connecting groove 10 is formed in the side face of a connecting part of the upper rod body 7, the connecting groove 10 is wedge-shaped, the structure of the lower rod body is consistent with that of the upper rod body, the upper end and the lower end of the connecting block 9 are respectively matched with the connecting grooves of the upper rod body and the lower rod body, and the upper rod body and the lower rod body are fixedly connected. The connecting block 9 comprises two same wedge blocks, the inclined planes of the small-volume ends of the two wedge blocks are tangentially fixed, so that the large-volume ends of the two wedge blocks are respectively exposed from top to bottom of the whole connecting block 9, and the large-volume ends of the wedge blocks are matched with the connecting grooves 10 and just inserted into the connecting grooves of the upper rod body and the lower rod body respectively to fixedly connect the upper rod body and the lower rod body. The two fixed wedge-shaped fixing blocks are inserted into the connecting grooves to fix the upper rod body and the lower rod body, and the upper rod body and the lower rod body are dismounted from the side faces, so that the operation is convenient, the fault tolerance rate is high, and the universality is high.
Except the railing in this application, the linking of other pipe fittings all can use this linking structure to connect, and convenient to use can not fall out from linking up the groove in order to guarantee to link up the piece, can also increase annular clamp at linking up the position and prevent the dislocation.
