Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] like Figure 1-7 As shown in , a pawl-type double-lock vehicle cab overturning device includes a support base 1, the support base 1 is sleeved with the large-end round rod 201 of the shaft rod 2 through a bearing 102, and the middle gear rod of the shaft rod 2 The tooth groove on 202 is fitted with the pawl 301 of the pawl mechanism 3, and the pawl mechanism 3 is symmetrically installed in the sleeve end hole 402 of the flip seat 4, and the small lug 302 of the pawl mechanism 3 is connected to the drag cable 6, and 6 After passing through the sleeve wall hole 405 of the turning seat 4 and the cable guide hole 5, the other end of the cable 6 passes through the drum 702 of the retracting mechanism 7, and the small end round rod 203 of the shaft rod 2 passes through the shaft sleeve It is symmetrically sleeved in the shaft hole 403 in the middle of the turning sea...

The invention discloses a pawl-type double-lock car cab overturning device which comprises a supporting seat. The supporting seat is connected with a big end round rod of a shaft rod in a sleeving mode through a bearing. Pawls of pawl mechanisms are matched with tooth grooves in a middle tooth rod of the shaft rod in a clamped mode. The pawl mechanisms are symmetrically mounted in barrel sleeve end holes of an overturning seat. Small supporting lugs of the pawl mechanisms are connected with an inhaul cable. After the inhaul cable penetrates through barrel sleeve wall holes of the overturning seat and inhaul cable guiding holes, the other end of the inhaul cable passes through a rotating barrel of a retracting and extending mechanism. Small end round rods of the shaft rod are symmetricallyarranged in shaft holes in the middle of the overturning seat in a sleeved mode through bearings. The pawl-type double-lock car cab overturning device is compact in structure, reasonable in design andnovel and unique in idea and is utilized to be connected with a chassis of a car, thus a cab can be overturned obliquely, cab inclination is facilitated, accordingly a power system of the car is conveniently overhauled, and meanwhile, the overturning angle of the cab is controllable; and meanwhile, the pawl-type double-lock car cab overturning device is a pure mechanical component and is reliablein connection, high in safety, long in life and convenient to maintain, and in addition, accidental inclining of the cab can be avoided through the pawl mechanisms.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a pawl-type double-lock automobile cab overturning device. Background technique [0002] The cab turning mechanism includes torsion bar turning mechanism and hydraulic turning mechanism; at present, almost 100% of flat-head cab heavy trucks support the turning function, and even light trucks that rarely have this function before are now more and more using turning technology . However, it is convenient to be reversible, but the complicated reversing mechanism will inevitably cause some problems. [0003] The light truck cab itself is heavy, and it is impossible to turn it over by manpower alone, so a power assist device is needed. The torsion bar type cab power-assisted turning mechanism has a simple structure and poor reliability, but with continuous use, the elastic force of the torsion bar will become lower and lower. If your cab uses this booster system, and the liftin...
