Abstract
The utility model discloses a liquid tank-type semitrailer tail bumper, solving a technical problem of providing a liquid tank-type semitrailer tail bumper with floating structure. To solve the technical problem, the utility model uses following technical solutions of a liquid tank-type semitrailer tail bumper, comprising a main tail bumper, a fixed support arranged under the main tail bumper, a swinging arm movably connected with the fixed support and a floating lower cross-bar arranged on the lower end of the swinging arm. Compared with the prior art, the floating lower cross-bar of the liquid tank-type semitrailer tail bumper can swing backwards, which not only satisfies safety regulations requirements in each country, but is also suitable for various uneven and specific road conditions.
Description
Technical field
The utility model relates to Bumper behind a kind of cylindrical liquid superimposed trailer.
Background technology
At present, the special vehicle manufacturing is when manufacturing the cylindrical liquid superimposed trailer both at home and abroad, and Bumper is stationary structure thereafter, and when road conditions were uneven, the easy and serious collision of road surface generation of back Bumper caused the damage of back Bumper.Simultaneously, many nation's security rules all require to be provided with the back Bumper, and this just causes existing cylindrical liquid superimposed trailer to be difficult to above-mentioned condition of simultaneous adaptation and requirement.
Summary of the invention
The technical problems to be solved in the utility model provides Bumper behind a kind of cylindrical liquid superimposed trailer of floating structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: Bumper behind a kind of cylindrical liquid superimposed trailer, comprise the main tail thick stick in back, and main tail thick stick below, described back is provided with fixed pedestal, described fixed pedestal is connected with swing arm, and described swing arm lower end is provided with the whippletree down that floats.
About fixed pedestal described in the utility model is arranged with two, described fixed pedestal is connected with the upper end of swing arm by the swing bearing pin.
Fixed pedestal described in the utility model inboard is welded with the reinforcement diagonal ligament and is connected with chassis side rail afterbody lower end.
Be provided with returning pull-spring between reinforcement diagonal ligament described in the utility model and the swing arm.
Fixed pedestal described in the utility model and swing arm are channel-section steel.
Whippletree is the shaped steel of long 100mm * wide 100mm, thickness 5mm under described in the utility model the floating.
The pulling force of returning pull-spring described in the utility model is 5kg, and the maximum of unsteady whippletree down pivot angle backward is 60 °, and the maximum lift limit is 137mm.
The utility model compared with prior art floats whippletree to swing backward, has both satisfied the requirement of security for all countries rules, can adapt to various up-and-down specific road conditions again.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a running condition scheme drawing of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, 2, Bumper behind the utility model cylindrical liquid superimposed trailer comprises the main tail thick stick 1 in back, two fixed pedestals 2 about being arranged with below the main tail thick stick 1 in back, and fixed pedestal 2 is connected with swing arm 3, and swing arm 3 lower ends are provided with the whippletree 7 down that floats.Wherein, fixed pedestal 2 is connected with the upper end of swing arm 3 by swing bearing pin 4, and fixed pedestal 2 inboards are welded with reinforcement diagonal ligament 5 and are connected with chassis side rail afterbody lower end, strengthen being provided with returning pull-spring 6 between diagonal ligament 5 and the swing arm 3.
When Bumper is produced behind the utility model cylindrical liquid superimposed trailer, be welded on the chassis side rail afterbody, about main tail thick stick lower end, back, respectively weld two fixed pedestal (10# by the main tail thick stick in back (is the carbon steel sheet bending and molding of the thick Q235 of 6mm by material)
The type channel-section steel), (material is 10# will to be welded on the swing arm that floats whippletree (material is the shaped steel of long 100mm * wide 100mm, the thickness 5mm) left and right sides, upper end again
The type channel-section steel) flexibly connects with fixed pedestal, promptly be drilled with the through hole that diameter is 18.5mm respectively in the upper end of fixed pedestal and swing arm, with diameter is that the swing bearing pin of 18mm is connected fixed pedestal with swing arm, and (material is 6# to strengthen diagonal ligaments in longeron afterbody lower end, the vehicle frame left and right sides and two of left and right sides fixed pedestal welding
The type channel-section steel), playing the effect of strengthening and fixing, between swing arm and reinforcement diagonal ligament, be that the returning pull-spring of 5kg is connected simultaneously with pulling force; Like this when running into scraggly road surface, the whippletree that floats down can maximum backward pivot angle β be 60 °, the maximum lift limit is 137mm, after rolling scraggly road surface away from, floating down, whippletree sets back under the effect of returning pull-spring automatically.
The utility model has creatively used floating structure, and when being applied to 40 cubes of pot type semi-mounteds and transporting oily special vehicle, the comprehensive manufacturing cost of back Bumper is about 550 yuan, materials used is 92kg, not only with low cost, and simple and practical, be particularly suitable for the semi-mounted special vehicle and use.
