Abstract
The utility model discloses a draw hook trolley based interchange control mechanism of a universal wheel and a directional wheel, which comprises a rear universal wheel that directs a rear spring pin; a location pin hole is arranged on a steering wheel of the rear universal wheel relative to the rear spring pin; a location pin hole is arranged on a steering shaft of the rear universal wheel relative to the rear spring pin; a draw hook is articulated with a trolley; the rear spring pin is connected with a pull rod which is articulated with the output end of a crank connection mechanism; and the input end of the crank connection mechanism is connected with a front spring pin of which the end surface is or is not in contact with the draw hook. The interchange control mechanism improves the control mechanism, thereby increasing the loading amount of the trolley in a vehicle carriage, reducing the amount of required transportation vehicles and saving the transportation cost.
Description
Technical field
The utility model belongs to the chassis technology of migrating in goods week, is specifically related to a kind of exchange control mechanism of controlling migrate in goods week directed rolling of chassis cardan wheel and universal rotation.
Background technology
Automobile manufacturing enterprise will use the turnover chassis during parts logistics turnover in process of production.What existing turnover chassis adopted is hauling hook side two orientations, traction tailstock side two universal mounting meanss, and promptly the hauling hook end of chassis adopts two cardan wheels, and the tail end of chassis adopts two directional wheels.Said structure can not use fork truck to go under the situation of car operation, makes chassis can only singlely put in logistics vehicles, has influenced load factor in the compartment greatly, causes the waste of logistics vehicles space, has increased logistics cost.Like this, trailing wheel is for directed when just needing a kind of can the traction on the road surface, and trailing wheel can change to universal caster wheel when packing the compartment into, makes things convenient for chassis laterally to enter the compartment, improves stow efficient.Existing orientation, universal conversion castor are independent hand pulling type operation, should not operate in limited space, compartment, and complicated operation.
Summary of the invention
The purpose of this utility model is to provide a kind of and exchanges control mechanism based on hauling hook chassis cardan wheel and directional wheel, to address the above problem.
The technical solution of the utility model is: exchange control mechanism based on hauling hook chassis cardan wheel and directional wheel, it comprises the back cardan wheel, the directed rear spring pin of back cardan wheel, offer dowel hole with respect to the rear spring pin on the steering handwheel of back cardan wheel, offer dowel hole with respect to the rear spring pin on the steering shaft of back cardan wheel, the hauling hook that is articulated and connected with chassis, the rear spring pin is connected with pull bar, the mouth of pull bar and crank connecting is articulated and connected, the input end of crank connecting connects the front spring pin, and the end face of front spring pin contacts with hauling hook or do not contact.
Described crank connecting comprises first fork that is articulated and connected with pull bar, and first fork is connected with rotating shaft, connects second fork in the rotating shaft, second fork pull bar that is articulated and connected, and pull bar connects the front spring pin.
It comprises at least two cardan wheels, connects relative first fork with the cardan wheel number in the rotating shaft, first fork pull bar that is articulated and connected respectively, and pull bar is connected with the rear spring pin.
This mechanism realizes directed the rolling and the exchange of universal rotation by the cardan wheel behind the hauling hook chassis of packing up and launch to control of the hauling hook on the chassis, does not need chassis is carried out operation bidirectional, realizes the fusion of normal drawing-in motion and control action.By the improvement of this control mechanism, improved chassis shipped quantity in the compartment, reduced required transport vehicle quantity, save traffic cost.
Description of drawings
Fig. 1 the utility model control mechanism master looks scheme drawing.
Fig. 2 the utility model control mechanism schematic top plan view.
Fig. 3 the utility model control mechanism schematic perspective view.
Fig. 4 the utility model control mechanism is located at the chassis scheme drawing.
The specific embodiment
This mechanism is the improvement on the existing chassis that has a hauling hook, as shown in Figure 4, hauling hook 1 is articulated and connected with chassis 2, two groups of cardan wheels before and after chassis connects for 2 times, near hauling hook 1 side be two cardan wheels of not changing 3, cardan wheel 4 is to realize directed the rolling and the cardan wheel of the exchange of universal rotation after two behind the chassis 2.
Realize two cardan wheels directed roll and the mechanism of the exchange of universal rotation under be described.
Exchange control mechanism shown in Fig. 1,4, have front spring pin 5 at the hauling hook 1 that is articulated and connected with chassis 2, when hauling hook 1 was packed up, hauling hook 1 can promote front spring pin 5.The end of front spring pin 5 is connected with crank connecting.
Crank connecting comprises the pull bar 6 that the end with front spring pin 5 is articulated and connected, pull bar 6 fork 7 that is articulated and connected, and fork 7 is connected with rotating shaft 8, and rotating shaft 8 connects forks 9, and fork 9 is articulated and connected with pull bar 10, and the other end of pull bar 10 connects rear spring pin 11.
On arrangement structure, shown in Fig. 2,3, the both sides of present embodiment shaft 8 connect two forks 9, and fork 7 is located at the middle part of rotating shaft 8, and two forks 9 are articulated and connected with two pull bars 10 respectively; The end of two pull bars 10 all is connected with rear spring pin 11, and is relative with the rotating disk of cardan wheel after two respectively.Pull bar 10 is connected with rear spring pin 11 by connecting rod 10.1 in the present embodiment.
Shown in Fig. 1,4, crank connecting is located at the underframe 2.1 times of chassis 2 in the layout of chassis, and rotating shaft 8 is supported on the underframe 2.1 by two bearing seats 8.1.The front end of front spring pin 5 stretches out the front end face 2.2 of chassis.
When hauling hook is packed up, hauling hook promotes front spring pin 5, front spring pin 5 promotes pull bar 6, pull bar 6 drives fork 7 and rotating shaft 8 rotations, fork 9 rotates pulling pull bar 10 simultaneously, break away from the dowel hole 4.4 of pull bar 10 pulling rear spring pins 11 from the rotating disk 4.2 of back cardan wheel, make the back cardan wheel become universal.Chassis can laterally push in the compartment;
When hauling hook launches, the bearing pin reduction of front spring pin 5, pulling pull bar 6 drives forks 7 and rotating shaft 8 commentaries on classics of circling round, and fork 9 rotates simultaneously, pushing drawing rod 10, the rear spring pin loosens, and during the traction chassis, the rotating disk 4.2 of back cardan wheel rotates, in the dowel hole 4.4 after the bearing pin of rear spring pin 11 inserts on the rotating disk 4.2 of cardan wheel, thereby reach directional effect under the effect of spring force.
