Detailed description of the invention
Structure that Figure of description illustrates, ratio, size etc., all contents in order to coordinate specification sheets to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that the utility model can produce and the object that can reach, all should still drop in the scope that technology contents that the utility model discloses can contain.Simultaneously, in this specification sheets, quote as " on ", the term such as D score, 'fornt', 'back', " centre ", also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, changing under technology contents, when being also considered as the enforceable category of the utility model without essence.
Be a kind of mechanical ascending and descending bridge construction of the utility model as depicted in figs. 1 and 2, described lift bridge is arranged on the cross member of frame 1 at vehicle body middle part, described lift bridge comprises middle base 2, two overlap the outer sleeve 3 and the inner sleeve 4 that match, described outer sleeve 3 is slidably enclosed within on the outer wall of inner sleeve 4, described outer sleeve 3 is provided with upper cover 31, inner sleeve 4 is provided with lower cover 41, between described upper cover 31 and lower cover 41, be provided with spring 5, described middle base 2 is arranged on the midway location of cross member of frame 1 bottom surface, described outer sleeve 3 is vertically arranged on the two ends of cross member of frame 1 bottom surface, the bottom of described inner sleeve 4 is provided with Connection Block 42, described Connection Block 42 is hinged by pull bar 6 and middle base 2, the bottom of described inner sleeve 4 is connected with suspension 7, hanging 7 is connected with wheel 9.Described outer sleeve 3 and inner sleeve 4 can play the effect of support, damping in the time that transport trolley travels in the place of Uneven road, so outer sleeve 3 and inner sleeve 4 have relative motion, the effect of described pull bar 6 is to improve the stability of inner sleeve 4 and then ensures outer sleeve 3 and the stable cooperation of inner sleeve 4.Being connected fit system and can having multiple of described pull bar 6 and Connection Block 42 and middle base 2, for example one end of pull bar 6 and Connection Block 42 are hinged, the other end has elongated slot and is connected by locating dowel pin with middle base 2, in the time of outer sleeve 3 and inner sleeve 4 relative motion, locating dowel pin can slide in elongated slot, prevents that pull bar 6 from occurring stuck, although this method can ensure the stability of inner sleeve, but aspect intensity, not very desirable, so described pull bar 6 is divided into driving lever 61 and follower lever 62 in the present embodiment, described driving lever 61 is hinged with the Connection Block 42 of inner sleeve 4, described follower lever 62 is hinged with middle base 2, follower lever 62 is socketed in and on the outer wall of driving lever 61, realizes the flexible of pull bar 6 entirety, in the time of outer sleeve 3 and inner sleeve 4 relative motion, driving lever 61 can slide in follower lever 62, this embodiment has not only ensured stability that outer sleeve 3 and inner sleeve 4 coordinate but also also very desirable aspect intensity.
In the time of real work, can produce friction when outer sleeve 3 and inner sleeve 4 relative motion, in order to increase the service life of outer sleeve 3 and inner sleeve 4, in the present embodiment, the inwall of described outer sleeve 3 is provided with interior friction sleeve 32, the outer wall of described inner sleeve 4 is provided with external friction cover 43, and described interior friction sleeve 32 and external friction cover 43 match.
The number that need to select for the weight that will carry spring 5 according to real work, in the present embodiment, described spring 5 is provided with two.Outer sleeve 3 in this structure and the shape of inner sleeve 4 also can be as required or the number of spring 5 determine, such as cylindrical shape, rectangular shape etc.; In the time only having a spring, outer sleeve 3 and inner sleeve 4 are that cylindrical shape or cuboid can; In the time following spring have, outer sleeve 3 and inner sleeve 4 are that rectangular shape is more suitable more.
In order to increase overall stability, between described middle base 2 and the Connection Block 42 of two inner sleeves 4, be connected with respectively two pull bars 6, because each side is all provided with two pull bars 6, even also can continue so a certain pull bar 6 of a side goes wrong the support that provides stable, prevent dangerous unexpected generation, improved transport trolley safety, ensured the personal security on transport trolley.
In the present embodiment, be also connected with multiple reinforcement gussets 8 between described outer sleeve 3 and cross member of frame 1, object is in order further to improve overall security and stability.
Taking towed vehicle as example, before towed vehicle comprises, rear steering bridge, this structure is arranged on the midway location of vehicle body as center axle, spring 5 between outer sleeve 3 and inner sleeve 4 is in half compressive state under normal circumstances, illustrate that by following two kinds of situations this structure is action principle: the first situation is in the time that towed vehicle goes up a slope, wheel on front steering axle on domatic then the wheel on steeraxle on level land during this period of time in, because spring 5 is in half compressive state, so in the time that vehicle body middle part is unsettled spring 5 launch to make to hang 7 band motor car wheels 9 move downward support to domatic on, the effect of supporting has been played in vehicle body middle part, and because the effect of pull bar 6 makes spring 5 can not launch easily or compress, also just further improved the weight that this structure can support, the second situation is that wheel on current, rear steering bridge and this structural wheel are all on domatic and front steering axle during by descending, because the major part of vehicle body is also all upper domatic, so wheel meeting perk in the time that transport trolley moves on front steering axle, and now because spring 5 is half compressive states, so because tare can make spring 5 continue compression, so just make whole vehicle body decline, the wheel on front steering axle also just can continue to be supported on domatic going up and can be not unsettled so.Below either way can make forward and backward steeraxle and carrying bogie at grade, also just make the wheel on each bridge support on the ground always, stop the generation of safety hazard and vehicle body damage problem.
In sum, a kind of mechanical ascending and descending bridge construction of the utility model, can solve large span and organize more transport trolley center axle or the unsettled problem of front-rear axle in the time of uphill/downhill and road surface hollow of vehicle bridge.So, have very high value and use meaning thereby the utility model has effectively overcome practical problemss more of the prior art.
Above-mentioned embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.The utility model also has many aspects under the prerequisite without prejudice to overall thought, to improve, and all can, under spirit of the present utility model and category, can above-described embodiment be modified or be changed for person skilled in the art scholar.Therefore, have in technical field under such as and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
