Abstract
The utility model discloses a manual locking mechanism for supporting a side door, and belongs to the technical field of pavers. The manual locking mechanism comprises a sleeve pipe, a core shaft, a compression spring, a position limit bolt and a rotary locking plate, wherein the sleeve pipe is fixed on the side door of a paver through a nut; the side door is provided with a slide way; the core shaft together with the compression spring are sleeved and mounted in a hole of the sleeve pipe in a sliding fit manner; the outer end of the core shaft is fixedly connected with one end of the rotary locking plate through a thread nut; and a circular hole formed at the other end of the rotary locking plate is inserted and mounted on a sliding pin connected with a side door support rod in a sliding fit manner. The manual locking mechanism has the beneficial effects of simple structure, high reliability and low cost, and is convenient for connection, adjustment, use and maintenance.
Description
Technical field
The utility model relates to the manual locking mechanism that a kind of side door supports, and belongs to the road construction work field of mechanical technique.Mainly be applicable to the manual simplified locking mechanism that the unlatching of road construction work machinery side door is supported.
Background technology
Paver belongs to road construction work machinery, and its working environment is extremely abominable.The side door of paver is the installation and maintenance door of dynamical system, and under the normal condition, side door is in closed condition.When needs keep in repair power, side door must be opened, and side door be supported, again with independent locking mechanism locking by support bar; Open for a long time side door at work and can cause the inefficacy of the independent locking mechanism of side door support, and then the inconvenience in work the mischief personal safety and the use.
Summary of the invention
For solving the problems of the technologies described above, the manual locking mechanism that the utility model provides a kind of side door to support can realize the double locking that side door supports, and it is more safe and effective that side door is opened.
The utility model is realized with following technical scheme: the manual locking mechanism that a kind of paver side door supports comprises sleeve pipe, mandrel, compression spring, caging bolt and spin locking plate; Sleeve pipe is fixed on the paver band slideway side door by nut, mandrel is sleeved in the hole of sleeve pipe together with compression spring sliding fit, fixedly connected with spin locking plate one end by screw nut in the mandrel outer end, the other end of spin locking plate is manufactured with circular hole, and the circular hole sliding fit is inserted on the sliding pin that connects the side door support bar.
The beneficial effects of the utility model are: mechanism is simple, connects easy to adjust, easy to use; The reliability height, with low cost, working service is convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cutaway view Amplified image at the A-A place of Fig. 1.
Among the figure: 1, frame, 2, support bar, 3, the spin locking plate, 3-1, circular hole, 4, caging bolt, 5, sliding pin, 6, band slideway side door, 6-1, slideway lock slots, 7, sleeve pipe, 7-1, nut, 8, mandrel, 8-1, screw nut, 9, the compression spring.
The specific embodiment
As depicted in figs. 1 and 2, paver side door supporting mechanism comprises the side door 6 that is installed in band slideway on the frame 1, and the side door 6 of band slideway is provided with slideway lock slots 6-1, supports the support bar 2 of side door 6 in addition, and support bar 2 usefulness sliding pins 5 are connected with side door.The manual locking mechanism that side door supports is made up of sleeve pipe 7, mandrel 8, compression spring 9, caging bolt 4 and spin locking plate 3; Sleeve pipe 7 is fixed on the paver side door 6 by nut 7-1, mandrel 8 is sleeved in the hole of sleeve pipe 7 together with compression spring 9 sliding fits, fixedly connected with spin locking plate 3 one ends by screw nut 8-1 in mandrel 8 outer ends, the other end of spin locking plate 3 is manufactured with circular hole 3-1, circular hole 3-1 sliding fit is inserted on the sliding pin 5, and sliding pin 5 is connected with side door support bar 2 by screw thread and uses nut check.
Principle is:
When opening: outwards spur spin locking plate 3, and rotation is inserted on the sliding pin 5 circular hole 3-1, sliding pin 5 enters among the slideway lock slots 6-1, enters first lock-out state this moment.Pull out spin locking plate 3, mandrel 8 moves with lockplate, compression compression spring 9.The spin locking plate 3 that turns clockwise then when sliding pin 5 is aimed in the hole, is decontroled spin locking plate 3.Automatically resilience is being pressed on the sliding pin 5 under the spring force effect under the effect of compression spring force 9.Fixedly sliding pin 5 is realized double locking in lock slots.
When falling side door: at first pull out spin locking plate 3, overcome the pressure effect of compression spring 9, away from sliding pin 5.Be rotated counterclockwise spin locking plate 3, when circular hole 3-1 aims at caging bolt 4, decontrol spin locking plate 3, resilience automatically under the effect of compression spring 9 power is being pressed on the caging bolt 4 under the spring force effect.Promote sliding pin 5 then away from the lock slots state that unlocks, close side door.
