Abstract
The invention discloses a manual locking mechanism supported by a side door of a spreading machine, which belongs to the technical field of spreading machines. The manual locking mechanism comprises a casing pipe, a mandrel, a compression spring, a limit bolt and a rotary locking plate, wherein the casing pipe is fixed on the side door (provided with slide rails) of the spreading machine by nuts; the mandrel and the compression spring are in the sliding fit way arranged in a hole of the casing pipe; the outer end of the mandrel is fixedly connected with one end of the rotary locking plate by nuts, and the other end of the rotary locking plate is provided with a circular hole; and the circular hole is in the sliding fit way and plugged in a sliding pin connecting a support bar of the side door. The invention has the advantages of simple structure, convenient connection and adjustment, convenient use, high reliability, low cost, and convenient operation and maintenance.
Description
Technical field
The present invention relates to the manual locking mechanism that a kind of paver side door supports, belong 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 that door is used in the installation and maintenance of dynamical system, and under the normal condition, side door is in closed condition.When needs keep in repair power, must side door be opened, and side door supported, again with independent locking mechanism locking through 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 present invention provides a kind of paver 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 present invention realizes with following technical scheme: the manual locking mechanism that a kind of paver side door supports comprises sleeve pipe, axle, compression spring, caging bolt and spin locking plate; Sleeve pipe is fixed on the paver band slideway side door through nut; Axle is sleeved in the hole of sleeve pipe together with compression spring sliding fit; The axle outer end is fixedly connected with spin locking plate one end through screw nut; 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 invention has the beneficial effects as follows: mechanism is simple, connects easy to adjust, easy to use; Reliability is high, and is with low cost, and working service is convenient.
Description of drawings
Fig. 1 is a structural representation of the present invention.
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, axle, 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, axle 8, compression spring 9, caging bolt 4 and spin locking plate 3; Sleeve pipe 7 is fixed on the paver side door 6 through nut 7-1; Axle 8 is sleeved in the hole of sleeve pipe 7 together with compression spring 9 sliding fits; Axle 8 outer ends are fixedly connected with spin locking plate 3 one ends through screw nut 8-1; The other end of spin locking plate 3 is manufactured with circular hole 3-1, and 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 through 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 gets among the slideway lock slots 6-1, gets into first lock-out state this moment.Pull out spin locking plate 3, axle 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.Automatic resilience under the effect of compression spring force 9 is being pressed on the sliding pin 5 under the spring force effect.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, automatic resilience 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.
