The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the application is described in further detail, but the application's embodiment is not limited to this.
The guard bar device of a kind of motor tank tuck tank deck of the application as shown in Figures 1 to 5, comprise and be installed on fence 1, the movable rail 2 of tank deck and support cylinder 9, movable rail 2 is installed in fence 1 and is positioned at two inner sides longitudinally, movable rail 2 comprises cross bar 21 and several montants 22, the upper end of montant 22 is connected with cross bar 21 by the first coupling assembling 3, the lower end of montant 22 is connected with montant permanent seat 5 by the second coupling assembling 4, and montant permanent seat 5 is welded in the inner side of fence 1, wherein:
The first coupling assembling 3 and the second coupling assembling 4 are aluminum casting, the first coupling assembling 3 comprises the first ears type Connection Block 31 that is welded in cross bar 21 and the first monaural type attaching parts 32 that is welded in montant 22 upper ends, the first ears type Connection Block 31 offers the first U-shaped groove, and the first monaural type attaching parts 32 is articulated in the first U-shaped groove by bolt 6;
The second coupling assembling 4 comprises the second ears type Connection Block 41 that is fixed on montant permanent seat 5 and the second monaural type attaching parts 42 that is welded in montant 22 lower ends, the second ears type Connection Block 41 offers the second U-shaped groove, and the second monaural type attaching parts 42 is articulated in the second U-shaped groove by bolt 6.
For large-scale motor tank tuck, longitudinal length very due to movable rail 2, need to manufacture and install a large amount of attaching partss, in prior art, be by machine up a large amount of U-shaped attaching parts, pivot pin and guard bar support saddle, and then montant is installed and is connected with cross bar with pivot pin by U-shaped attaching parts, montant is installed and is connected with the outside of fence by guard bar support saddle, and its manufacture and mounting process are very loaded down with trivial details; And the first coupling assembling 3 of the application and the second coupling assembling 4 adopt the manufacturing process of aluminum casting, only need get final product time processing moulding by mould, do not need machine up and a large amount of attaching partss is installed, thereby greatly having simplified manufacture and the mounting process of movable rail 2, having reduced productive costs.
Concrete, the first monaural type attaching parts 32 and the second monaural type attaching parts 42 all offer for wearing the screw of bolt 6, the aperture of screw is greater than the diameter of bolt 6, thereby having realized the first monaural type attaching parts 32 rotates with respect to the first ears type Connection Block 31, the second monaural type attaching parts 42 rotates with respect to the second ears type Connection Block 41, be convenient to the lifting and swinging of movable rail 2, make operation more flexible.
Concrete, in screw, be embedded with abrasionproof steel bushing, prevent that the first monaural type attaching parts 32 and the second monaural type attaching parts 42 from rotating the wearing and tearing that produce.
The application is installed in fence 1 by movable rail 2 and is positioned at two inner sides longitudinally, makes movable rail 2 can access the protection of fence 1, is not easy to be damaged, and has improved the service life of movable rail 2, reduces maintenance cost.
In the present embodiment, the direction bending that the bottom of montant 22 swings towards movable rail 2 forms bending angle, and bending angle is greater than 90 degree, and object is can be arranged in parallel with cross bar 21 in order to realize montant 22.
Concrete, bending angle is set to 135 degree.
During use, when the piston rod that supports cylinder 9 is by montant 22 jack-up, make movable rail 2 when guard mode, montant 22, by the rotation of the first monaural type attaching parts 32 and the second monaural type attaching parts 42, finally makes montant 22 setting vertical with cross bar 21;
When supporting the piston rod retraction of cylinder 9, montant 22 counterclockwise swings 90 degree, the direction bending swinging towards movable rail 2 due to the bottom of montant 22 forms the bending angles of 135 degree, just realizing montant 22 be arranged in parallel with cross bar 21, while now not needing to use movable rail 2, movable rail 2 was fallen completely and can not be affected the safe in operation of motor tank tuck.
Concrete, montant permanent seat 5 is set to inverted U-shaped aluminium sheet, and the top of inverted U-shaped aluminium sheet and the second ears type Connection Block 41 are bolted to connection, and because this structure of inverted U-shaped aluminium sheet is more easily processed, manufacturing process is simple.
Concrete, the bending part of montant 22 bottoms is provided with brace panel 7, thereby improves the mechanical strength of bending part.
The rod end that supports cylinder 9 is fixedly connected with brace panel 7, the cylinder body end that supports cylinder 9 is fixed on the inner side of fence 1, the bottom bending of montant 22 is 135 degree angles, has reserved extendable room to the piston rod that supports cylinder 9, can adopt the support cylinder of more flexible stroke.
In the present embodiment, cross bar 21 is made by circular aluminum pipe, and because circular aluminum pipe is not easy to rupture, safety performance is better.
In the present embodiment; the movable rail 2 that is positioned at 1 two inner sides of fence connects by rail horizontal rod 8; the two ends of rail horizontal rod 8 are connected with two montants 22 that are positioned at movable rail 2 extreme ends respectively; make the movable rail 2 of two inner sides connect while lifting in aggregates inclosure roof walkway, play better protective effect.
The middle part of montant 22 offers bolt hole, is provided with for the fixing bolt assembly of steel rope 10 in bolt hole, is fixedly connected with, to strengthen the fastness of montant 22 between adjacent montant by steel rope 10.
Finally should be noted that; above embodiment is only in order to illustrate the application's technical scheme; but not restriction to the application's protection domain; although the application has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the application's technical scheme, and not depart from essence and the scope of present techniques scheme.
