Background technology
Since reform and opening-up, national economy obtains rapid growth, and " scientific and technical innovation, autonomous innovation " become the main flow of current domestic industry development, and China's industry is just progressively to the future development of intensive style, energy-saving and emission-reduction, low-carbon (LC).When society is fast-developing, the people's living standard is also progressively improving, and automobile becomes the indispensable walking-replacing tool that people go out, and the increase of automobile demand amount has promoted the development of auto-industry.In auto assembly line, auto body need to complete a plurality of assembly technologies, and chassis assembling line is an important technique assembling link.In car chassis fitting line, need to adopt suspender to carry out the vehicle body of carrier.Traditional vehicle body lifting appliance generally adopts the L shaped suspender of opening type, and it is L shaped that the vehicle body of this suspender supports arm, arm expansible.Before general employing of vehicle body support of L shaped suspender, the rear pin formula of pin or front pin butt formula are two kinds.After front pin, sell in the suspender of formula, the locating dowel pin that L shaped arm lower end arranges, not only has positioning action but also work to support vehicle body.And front pin butt formula suspender adopts two locating dowel pins and two modes that support fast front and back combined support, locating dowel pin plays the role of positioning, and back-up block plays a supportive role.Because suspender is to be suspended on track crane to hang up, after car body is laid on suspender, when suspender runs to uphill/downhill and when bend is transplanted, can have certain moving between car body and suspender, easily cause the generation of potential safety hazard.When car body is laid on suspender, how allowing car body accurately be placed on smoothly the rational position of suspender and keeping the stationarity of suspender is a difficult problem for puzzlement automobile load transfer device producer always.In order to address the above problem, scientific research personnel of the same trade and technical personnel, by continuous research and discovery, although make some progress technically, still exist the technical barrier not yet overcoming in practice.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, and a kind of chassis line locking lifting appliance is provided.This suspender adopts locking positioning pin assemblies is set on arm supporting leg, this locking positioning pin assemblies can not only make suspender held stationary in carrying car body process, also there is automatic aligning, locking, positioning function, can guarantee production and transport safety, can increase work efficiency again; On suspender carrier bar, be provided with Si Ge balance wheel mechanism, balance wheel mechanism can suspender enter switching or make during process Installation vehicle body more steadily, safety, improve suspender switching and setting accuracy simultaneously, and then improve the shop characteristic of product.
The utility model solves the technical scheme that its technical matters adopts: contain rear arm, oil drain pan, balance wheel mechanism, carrier bar, front arm, rotating support shaft, locking positioning pin assemblies, arm supporting leg, arm adjustment seat, carrier bar is rectangular frame structure, intermediate position is provided with a crossbeam, on the longitudinal load-bearing beam at crossbeam end positions place, be respectively provided with a bearing pin vertically arranging, on four jiaos of carrier bar upper surface, be provided with Si Ge balance wheel mechanism, balance wheel mechanism is installed in the outside on two long limits, the below of carrier bar is provided with the oil drain pan that a concentricity line is placed, oil drain pan is oblong-shaped, its width is slightly shorter than carrier bar, Length Ratio carrier bar is slightly long, four jiaos of place's bolts of carrier bar lower surface are fixed with four arm adjustment seats, between the arm adjustment seat of every two horizontal positions, be provided with a rotating support shaft, rotating support shaft skin is arranged with rotating support shaft axle sleeve, arm and rear arm before the two ends of rotating support shaft axle sleeve are respectively equipped with, front arm and rear arm are also fixed on the axle sleeve of rotating support shaft with reinforcement gusset, the vertical arm supporting leg that is fixed with of end at front arm and rear arm, and arm supporting leg arranges to the inside, at each arm supporting leg front end, be provided with locking positioning pin assemblies, locking positioning pin assemblies is fixedly connected by two bolts and arm supporting leg, formed a kind of chassis line locking lifting appliance.
The utility model solves the know-why that its technical matters adopts: the locking positioning pin assemblies in this suspender is to adopt eccentric stiffener principle design to form.When elevator is delivered to car body on suspender, arm, under opening mechanism auxiliary, launches to both sides, and when elevator is lifted to car body after specified altitude assignment, arm is auxiliary lower closed opening mechanism.After elevator is placed into car body on the arm supporting leg of suspender, the locking positioning assembly on arm supporting leg is corresponding one by one with the knock hole on chassis of vehicle body, locking positioning pin assemblies auto lock, location, and car body pulsation-free is placed on suspender.But, when car body is placed on after hanger support leg, and the knock hole of chassis of vehicle body does not have the fix shaft corresponding matching accurately and on locking positioning pin assemblies, car body produces certain pressure to the fix shaft on locking positioning pin assemblies under own wt effect, when pressure surpasses the ultimate pressure of fix shaft setting, eccentric fix shaft rotates.If the pressure that eccentric fix shaft is subject to exists always, be that locking positioning pin assemblies is failed and chassis knock hole corresponding matching, fix shaft can rotate always, until just stop operating with the knock hole corresponding matching of chassis, complete self-aligning function, and auto lock location.Car body after locking positioning does not produce displacement in the time of can not transplanting because of uphill/downhill or bend in suspender course of conveying, has guaranteed transportation safety.Simultaneously, in order to make suspender make vehicle body operation more steady when entering switching or process Installation, this suspender adopts Si Ge balance wheel mechanism is set on four jiaos of carrier bar, the righting track that this balance wheel mechanism hangs up with track crane in suspender transportation contacts with rolling, can make suspender when entering switching or process Installation, make vehicle body move more steady, safety, can improve again suspender switching and setting accuracy, and then improve the shop characteristic of product simultaneously.
The beneficial effects of the utility model are: this suspender is compared with prior art located more accurate, there is automatic aligning, automatic fastening function simultaneously, and operate steadily, safety, when improving the transport efficiency of suspender, improve suspender switching and setting accuracy, and then improved the shop characteristic of product.
