Abstract
The invention discloses a kind of drawing and pulling type fire fighting truck ladder, it includes horizontal guide rail assembly, top layer step plate, upper limit bar, upper connecting rod, middle level step plate, bottom step plate, handle, lower connecting rod and lower limit bar.Described top layer step plate is flexibly connected with horizontal guide rail assembly, described upper connecting rod is parallel with lower connecting rod, it is connected with the many groups of articulating devices being made up of with middle level step plate upper limit bar between described upper connecting rod and lower connecting rod, described bottom step plate is provided with handle.The present invention can use easily and efficiently, and movable hydraulic cleans device and utilizes the feature of parallel-crank mechanism to realize the folding of ladder, utilizes guide rail and slip bocks system to realize the horizontal extension of ladder.
Description
Technical field
The invention belongs to mechanical field, particularly relate to a kind of drawing and pulling type fire fighting truck ladder.
Background technology
At present, in the design process of 25 meters of high-jetting vehicles, because the jib of high-jetting vehicle is heavier, water pot etc., other devices are arranged on the position, front end of vehicle rear axle, before do not tend to have position conventional ladder be installed.Because 25 meters of high-jetting vehicle back platform are told somebody what one's real intentions are, about at 1.5 meters of height, conventional ladder is installed without space.Conventional ladder is necessarily mounted at the outer surface of vehicle body, is difficult to be designed to built-in.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of convenient and swift, utilize guide rail and slip bocks system to realize the drawing and pulling type fire fighting truck ladder of horizontal extension of ladder.
The present invention takes techniques below scheme to realize: a kind of drawing and pulling type fire fighting truck ladder, it includes horizontal guide rail assembly, top layer step plate, upper limit bar, upper connecting rod, middle level step plate, bottom step plate, handle, lower connecting rod and lower limit bar, described top layer step plate is flexibly connected with horizontal guide rail assembly, described upper connecting rod is parallel with lower connecting rod, it is connected with the many groups of articulating devices being made up of with middle level step plate upper limit bar between described upper connecting rod and lower connecting rod, described bottom step plate is provided with handle.
The method have the advantages that the present invention can use easily and efficiently in sum, movable hydraulic cleans device and utilizes the feature of parallel-crank mechanism to realize the folding of ladder, utilizes guide rail and slip bocks system to realize the horizontal extension of ladder.
Accompanying drawing explanation
Fig. 1 is population structure schematic diagram of the present invention；
Wherein: 1, horizontal guide rail assembly；2, top layer step plate；3, upper limit bar；4, upper connecting rod；5, middle level step plate；6, bottom step plate；7, handle；8, lower connecting rod；9, lower limit bar.
Detailed description of the invention
As shown in Figure 1, a kind of drawing and pulling type fire fighting truck ladder, it includes horizontal guide rail assembly 1, top layer step plate 2, upper limit bar 3, upper connecting rod 4, middle level step plate 5, bottom step plate 6, handle 7, lower connecting rod 8 and lower limit bar 9, described top layer step plate 2 is flexibly connected with horizontal guide rail assembly 1, described upper connecting rod 4 is parallel with lower connecting rod 8, it is connected with the many groups of articulating devices being made up of with middle level step plate 5 upper limit bar 3 between described upper connecting rod 4 and lower connecting rod 8, described bottom step plate 6 is provided with handle 7.
Detailed description of the invention: drawing and pulling type fire fighting truck ladder, movable part is fixed on horizontal guide rail assembly 1, can horizontally slip on horizontal guide rail, when drawing and pulling type fire fighting truck ladder uses at retracted mode, handle 7 of can holding with a firm grip manually, move right, drawing and pulling type fire fighting truck ladder movable part, because of action of gravity, lets droop, during the longest position of supreme gag lever post 3 and lower limit bar 9, ladder completes to launch operation, and fireman can top bar to the position needed at station step by step.During contraction the most contrary with foregoing description action.
The above is embodiments of the invention, therefore all equivalence changes done according to structure, feature and the principle described in the present patent application scope or modification, in the range of being all included in present patent application.
