The support leg device of the utility model embodiment can be applicable on the support leg device of engineering truck (as hoisting crane, fire fighting turnable ladder, high spray fire extinguishing tanker and Elevating platform fire truck etc.) with support foot plate.Fig. 1 is the structural representation of the support foot plate of the utility model embodiment.Please refer to Fig. 1, support foot plate comprises pedestal 10, attaching parts 20 and a plurality of connecting element 30, and by connecting element 30, pedestal 10 being captiveed joint with attaching parts 20 becomes a detouchable integral structure.
The material of attaching parts 20 is Steel material, is welded by certain thickness normal thin plate.Please refer to the drawing 4 and Fig. 5, attaching parts 20 comprise two blocks of side plates 220, two base plates 221, two top boards 222, and connecting panel 223, and each piece plate is welded to each other and forms, the zinc-plated processing of each plate surface.Two base plates 221 are connected to the bottom of two blocks of side plates 220, and mutually vertical with side plate 220; Base plate 221 is arc, the outer rim of its arc is identical with the external profile diameter of the annular top surface 121 of pedestal 10, have three through holes 244 on each piece base plate 221, these three through holes 244 are corresponding with three fixed orifices 144 of each group on the annular top surface 121 of pedestal 10 respectively, captive joint with the fixed orifice 144 on pedestal 10 after passing through hole 244 by connecting element 30, after connecting, the outer rim of base plate 221 is concordant with the outer rim of the annular top surface 121 of pedestal 10, as Fig. 1; Two top boards 222 are connected to the top of two blocks of side plates 220, connecting panel 223 connects the same end of two top boards 222, make between two top boards 222 and connecting panel 223 and connect into the U-shaped structure, this U-shaped structure other end relative with connecting panel 223 forms open end; Have two groups of respectively coaxial perforation 240 on side plate 220, after the bulb of Vertical Cylinders breaks away attaching parts 20 from the open end one of attaching parts 20, the bulb position of Vertical Cylinders is fixed by two set pin (not shown) by two groups of coaxial perforation 240.In addition, the sharp corner of attaching parts 20 is made chamfered.
In the present embodiment, connecting element 30 is bolt, and the quantity of the fixed orifice 144 on the annular top surface 121 of its quantity and pedestal 10 is identical, and fixed orifice 144 can be tapped bore.
During use, the bulb of the Vertical Cylinders of bracing or strutting arrangement slips into attaching parts 20 by the open end of attaching parts 20, then bulb enters in the groove 124 of end face 121 of pedestal 10, pass the through hole 244 of attaching parts 20 and captive joint with the fixed orifice 144 on the end face 121 of pedestal 10 by connecting element 30, pass two groups of perforation 240 on two blocks of side plates 220 of attaching parts 20 with two set pins at last, be stuck in the neck location of bulb by two top boards 222 and two set pins, thereby the position of bulb is fixed.
Removably be connected and fixed by connecting element 30 between the pedestal 10 of the support foot plate that the utility model embodiment provides and attaching parts 20, the forming composite structure support foot plate, the support foot plate of comparing conventional steel has the following advantages:
1, novel structure, technique are simple.The composite structure support foot plate is connected to become detouchable composite monolithic structure by bolt with attaching parts and pedestal, new in structure, and nylon monomer-cast nylon pedestal employing mould molding, and technique is simple; And traditional steel support foot plate is whole by welding fabrication, and technique is loaded down with trivial details, labour intensity is large.
2, reduced support foot plate weight.The density of material of nylon monomer-cast nylon is only 1/7 left and right of steel, adopts nylon monomer-cast nylon (MC nylon) to make the pedestal of support foot plate main body, can greatly reduce support foot plate weight, and carrying and installation aspect have reduced labour intensity.
3, composite monolithic structure, a certain component wear only need to be dismantled replacement and get final product, and need not integral body and scrap.And the support foot plate of conventional steel is welded as a whole, and the easy collision deformation of attaching parts causes damaging integral body and scraps.
4, the new in structure of composite structure support foot plate pedestal.The cylindrical sides of the optimum structure pedestal by force analysis, optimal design adds level and smooth circular cone inclined design, and pedestal is level and smooth plane and without thin spot (as protruding points such as reinforced ribs), make the whole stressed optimum of pedestal.
5, pedestal withstanding corrosion, good weatherability.Nylon monomer-cast nylon belongs to non-metallic material, is exposed in air can not get rusty, and has excellent ageing resistance; And the support foot plate of conventional steel surface paint and surface treatment are easily destroyed, and steel are corroded the generation corrosion, particularly are under the ocean operation environment.
6, pedestal is wear-resisting, antiskid capability is excellent.The molecular chain structure that the nylon monomer-cast nylon material is special makes material have high crystallinity, and the wear resisting property of material is excellent, adds suitable anti-wear agent, slip proofing agent and also can reach the purpose that improves antiskid capability in the moulding polymerization process; And the support foot plate of conventional steel is not wear-resisting, and is particularly not anti-skidding under freezing weather.
7, adopt the composite structure support foot plate, utilize new material to make support foot plate, except the shortcoming that can overcome the conventional steel support foot plate, can also introduce the engineering truck industry to new material, new ideas, for the products such as hoisting crane bring bright spot, increase the product attention rate.
the above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art, within not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be not break away from the technical solutions of the utility model content, any simple modification that foundation technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
